DESC:FIELD OF INVENTION:
The present invention relates to the field of mechanical clamping devices, more specifically to a device designed for clamping blade moulds during a bonding process . Further the device is configured to apply precise and uniform compressive force to blade moulds, ensuring their secure alignment and bonding under controlled conditions.

BACKGROUND OF INVENTION:
Most wind turbines have three blades which are made mostly of fiberglass. Turbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.

Wind turbine rotor blades are the most highly stressed and vital component of any wind turbine. They are designed to absorb the kinetic power of the wind and convert the said energy into a rotary motion around a central hub. While the central hub of the blades rotating at a gently speed relative to the wind, the tips of the blades are rotating at a much higher velocity and the longer the blade is, the faster the tip rotates especially for propeller type blade designs.

Conventionally wind turbine blades are attached to a steel hub using a detachable mechanical joint. These root joints are highly loaded and experience a very high number of load cycles. Because of the existing experience in this ?eld and the similarities with the joints for segmented blades these joint types are candidates for blade segmentation.

The present invention relates to an assembly of moulds. The said assembly of mould is particularly meant for the manufacturing of the blades for wind turbines. A single blade consists of two halves, which are first made individually in the mould parts and then moved in the mould parts by means of the mouldings, moved toward each other in a joining direction perpendicular to the longitudinal direction of the mouldings and thereby finally brought into a joining position and in the joining position be joined together.

Moulding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mould or matrix. The said mould itself have been made using a pattern or model of the final object. A mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mould, adopting its shape. A mould is a counterpart to a cast. The very common bi-valve moulding process uses two moulds, one for each half of the object.

Typically, in the industry, blades of wind turbine are manufactured by the bi-valve moulding process. In the said process, the blade is manufactured in two parts, i.e., the two halves, and then the said halves of the blade are joined at their complementary edges to form an entire wind turbine blade.

Each of the two halves of the wind turbine blade are formed using a mould or matrix having the shape and structure of one half of the root joint. The mould or matrix for manufacturing one half of the root mould primarily comprises of a positive mould and a negative mould. The shape of a root joint is roughly cylindrical, therefore, one half of the said root joint is semi-cylindrical. The curvature of the outer or convex surface of the positive mould is such that it is congruent to the curvature of the inner concave surface of one half of the root joint. Similarly, the negative mould is also a curved concave surface wherein the inner or the concave surface of the negative mould is congruent to the outer convex surface of the said half of the root joint.

In one embodiment of the present invention, the wind turbine blade is made of glass fibres. To form one half of the wind turbine blade, a plurality of sheets of glass fibre are placed on top of the convex surface of the positive mould. And then the said plurality of sheets of glass fibre are compressed over the positive mould by placing and pressing the negative mould over the sheets of glass fibre placed over the positive mould. The compressive force produced between the convex surface of the positive mould and the concave surface of the negative mould press the various layers of the glass fibre together and due to the malleable structure of the glass fibre, the said sheets of glass fibre get bonded to each other.

Typically, at one instance a specific number of fibre glass sheets are compressed between the positive mould and the negative mould. Once the said numbers of the glass fibre sheets are compressed between the positive mould and the negative mould, the negative mould is lifted and another set of the specific number of glass fibre sheets is placed on top of the previously compressed glass fibre sheets and the compressing process is repeated. The said process is repeated until the desired number of glass fibre sheets is reached.

Similarly, the wind turbine blade is formed in two halves. Once, the said two halves are ready, they are assembled together to form an entire wind turbine blade. The assembly of the said two halves of the wind turbine blade is done by placing the one half of the moulded wind turbine blade onto another half of the while ensuring the edges are perfectly matched with each other.

The said edges of the two halves of the wind turbine blade are bonded together with an adhesive. A compressive force is required for the bonding of the edges of the two halves of the wind turbine. Since, the mere weight of one half of the moulded wind turbine blade, along with the mould apparatus, is not enough to generate the required compressive force necessary for the bonding, a separate means is needed for creating the compressive force for the bonding.

The present invention provides a means for the compressing of the edges of the two halves of a wind turbine blade formed by the process of moulding in order to bond of the said edges together with an adhesive.

Considering the significant lengths of the wind turbine blades, the said process of the manufacturing demands a lot of precision for the manufacturing of blades having no faults as the tiniest of faults lead to operational failure.

The present invention is to provide the device for clamping blade moulds during the bonding process, comprising a bottom part (100), a top part (200), a connector part (300), and an actuator (400) assembly. The bottom part (100) includes a rigid bottom attachment member designed for secure affixation to a stationary bottom mould, a set of bottom main members (102) that provide structural support and facilitate the vertical movement of the top part (200) via engagement with a pin, and an actuator housing (103) that protects and houses the actuator assembly (400). The actuator cylinder (401), housed within the actuator housing (103), generates a vertical compressive force necessary for the bonding process. The top part (200) consists of a top main member (201) and top attachment members (202) that secure the top part (200) to a rotating top mould, with adjustable features to accommodate varying mould sizes. The actuator assembly (400) is designed to provide uniform compressive force during the bonding process, with a hydraulic or pneumatic actuator cylinder and optional pressure-regulating valves to ensure consistency and safety during operation. The connector part (300) engages with the bottom main members (102) through a pin-slot mechanism to restrict movement to the vertical direction, ensuring precise alignment and vertical translation during compression.

In the present invention is to provide the device for clamping blade moulds during the bonding process () comprises a bottom part (100) and a top part (200), working together to provide a secure and controlled clamping mechanism during the bonding operation. An embodiment of the present invention is to provide the bottom part (100), which includes a bottom attachment member (101). The bottom attachment member is a rigid, flat structure designed to securely attach the device to a stationary bottom mould. It is equipped with multiple holes for fasteners, ensuring the bottom part is firmly affixed to the mould. Additionally, the attachment member features reinforcement ribs, which enhance its rigidity and provide increased support during the compression process.
An embodiment of the present invention is the bottom main members (102), which are elongated plate structures that provide support and stability to the bottom part. Another embodiment of the present invention is to provide Bottom Main Member is equipped with a slot (104) at its upper end, which is purposefully configured to accommodate a pin (303) from the actuator assembly (400). The slot (104) facilitates the vertical displacement of the pin within a predetermined range, ensuring that proper alignment is maintained between the top and bottom parts during the clamping process. The bottom attachment member (101) is equipped with a series of reinforcement ribs integrated along its surface, enhancing the overall structural integrity. The ribs are designed to increase the member's rigidity, particularly during compressive loading, by redistributing applied forces and reducing deformation. The added ribs improve the component’s resistance to bending or warping, thereby maintaining stability and performance under mechanical stress.

Another embodiment of the present invention, the actuator housing (103) is a compartment integrated into the bottom part, designed to enclose and protect the actuator assembly (400). The housing serves as a secure housing for the actuator components, ensuring their proper positioning and functionality during the clamping operation. To enhance the operational efficiency and longevity of the system, the Actuator Housing (103) is equipped with an integrated thermal management system. The system is designed to regulate the temperature of the actuator assembly during operation, preventing excessive heat buildup that could otherwise lead to overheating or premature wear of the actuator components. By maintaining the actuator within its optimal thermal operating range, the thermal management system ensures consistent performance, reduces the risk of thermal damage, and extends the service life of the actuator assembly, thereby improving the overall reliability and efficiency of the clamping device.

In one embodiment of the present invention, the top main member (201) serves as the primary structural support for the top part of the clamping device. The member is fabricated from high-strength materials, such as steel, aluminum, or composite materials, which provide exceptional resistance to deformation under the significant stresses experienced during the bonding process. These materials ensure that the Top Main Member (201) maintains its rigidity throughout the operation, preserving the precise alignment of the top part (200) relative to the bottom part (100), which is critical for achieving an accurate and effective bonding process.

In another embodiment of the present invention, the top attachment members (202) are mounted perpendicularly to the top main member (201) and are responsible for securing the top part (200) to the rotating top mould. These attachment members (202) are designed with versatile fastening features, including bolts, screws, or quick-release mechanisms ,which enable convenient attachment and detachment during setup, maintenance, or mould changes. The inclusion of quick-release mechanisms allows for efficient disassembly and reassembly, minimizing downtime and optimizing operational flexibility. Additionally, the Top Attachment Members (202) are designed to be adjustable in length providing the adaptability required to accommodate moulds of varying dimensions. In some configurations, the top attachment members (202) are further equipped with vibration-damping elements. These elements help reduce the transmission of vibrations from the rotating top mould to the top main member (201), minimizing the potential for vibrational interference that could negatively impact the bonding process, ensuring a more stable and precise clamping operation.

In one embodiment of the present invention, the actuating cylinder (401) is a critical component of the actuator assembly (400), responsible for generating the vertical movement necessary to apply compressive forces between the top and bottom parts (200 &100) of the clamping device. The actuating cylinder (401) is connected to the actuator arm (402), and through its retracting and extending motion, it adjusts the separation between the top and bottom moulds. The movement creates or relieves compressive force, which is essential for achieving the required clamping pressure during the bonding process. The actuator cylinder’s (401) precise control over the vertical displacement is vital for maintaining accurate alignment and optimal pressure during mould compression.

In another embodiment of the present invention, the actuator arm (402) serves as the mechanical link between the actuating cylinder and the connector part (300). One end of the actuator arm (402) is connected to the actuating cylinder (401), while the other end is attached to the connector part (300). As the actuating cylinder (401) retracts or extends, the actuator arm (402) moves accordingly, translating the cylinder’s motion into compressive or relieving force on the top and bottom parts (200 &100). The movement is crucial for fine-tuning the alignment and pressure between the mould halves during the bonding process, ensuring that the proper clamping force is applied uniformly across the mould perimeter.

In yet another embodiment, the Intermediate Connecting Structure (304) is employed to provide a rigid and stable connection between the actuator arm (402) and the connector part (300). The structure ensures that the motion of the actuator arm (402) is efficiently transferred to the connector part (300), allowing for the precise and consistent application of clamping force during the bonding process. By maintaining a rigid connection, the intermediate structure (304) helps preserve the integrity of the actuator assembly (400), preventing any misalignment or loss of force transmission during operation.

Furthermore, in another embodiment of the present invention, the actuator cylinder (401) is fluidly coupled to a Hydraulic or Pneumatic Source. The fluid coupling allows for precise control over the vertical movement and compressive force applied by the actuator cylinder (401). The hydraulic or pneumatic system enables accurate regulation of both force and displacement, ensuring that the applied clamping pressure remains consistent and uniform throughout the bonding process. The capability is essential for achieving high-quality bonding results, as it guarantees that the compressive force is evenly distributed across the mould halves, preventing any localized pressure variations that could compromise the bonding process.

In one embodiment of the present invention, the connector part (300) is a component in ensuring the proper alignment and operation of the clamping device. The top Face (301) of the connector part is equipped with a series of mounting holes, which facilitate the adjustable attachment of the connector part (300) to the top part (200) of the system. The mounting holes provide flexibility in positioning, allowing for precise alignment between the top (200) and bottom (100) parts during the clamping process. By enabling adjustments in the connector part's (300) attachment, the system ensures that the necessary forces are applied uniformly, maintaining the accuracy and effectiveness of the clamping operation.

In another embodiment, the bottom face (302) of the connector part (300) plays a crucial role in the vertical displacement mechanism of the clamping device. The bottom face is equipped with a pin (303), which engages with the slot located in the bottom main members of the bottom part. The pin (303) is integral to the clamping process, facilitating vertical movement and ensuring the secure engagement of the connector part with the bottom main members. This pin allows for the controlled movement of the top part relative to the bottom part (100) during the clamping operation, enabling the application and relief of compressive forces.

The bottom face also feature a tapered section adjacent to the pin, which aids in the alignment and insertion of the pin into the corresponding slot in the bottom main members. The tapered design simplifies the engagement process by guiding the pin into position, reducing the potential for misalignment and ensuring smooth operation. Additionally, the bottom face equipped with a cushioning material surrounding the pin (303). The cushioning serves to reduce the impact and friction between the pin and the slot during vertical translation, thereby minimizing wear on both components. The cushioning material ensures that the pin slides smoothly within the slot, enhancing the efficiency and longevity of the clamping device by reducing the potential for friction-induced damage.

In one embodiment of the present invention, the clamping mechanism is designed to precisely control the compressive forces applied during the bonding process. The actuator assembly (400) is responsible for retracting the actuator cylinder (401), which causes a reduction in the separation between the top and bottom parts of the device. The retraction generates a compressive force at the mating edges of the top and bottom moulds, effectively securing the mould halves in place for bonding. The actuator cylinder’s ability to retract and extend allows for dynamic control of the mould separation, which is essential for achieving the desired clamping pressure.

Once the bonding process is completed, the actuator cylinder (401) extends, restoring the separation between the top and bottom parts. This extension relieves the compressive force, allowing for the safe removal of the clamping pressure and the disengagement of the mould halves. The retracting and extending actions of the actuator cylinder are fundamental to the operational sequence, ensuring that the moulds are securely clamped during bonding and adequately separated post-bonding.

To further enhance the control over the clamping process, the device is equipped with pressure-regulating valves. These valves are integrated into the actuator assembly to ensure that the applied compressive force remains within a predefined range. By regulating the pressure, the system prevents over-pressurization, which could otherwise lead to excessive strain on the moulds or damage to the components. The inclusion of pressure-regulating valves ensures that the clamping mechanism operates within safe and optimal parameters, thereby maintaining the integrity of the moulds and promoting consistent, high-quality bonding results.

In an embodiment of the present invention, the fasteners and mounting features are designed to enhance the ease of assembly, disassembly, and durability of the clamping device. The fasteners used to secure the bottom attachment member (101) to the stationary bottom mould are equipped with quick-release mechanisms. These quick-release fasteners allow for rapid attachment and detachment, streamlining the process of mould changes or maintenance activities. The quick-release design ensures minimal downtime during operational transitions and maintenance procedures, improving overall system efficiency.

Additionally, the bottom attachment member (101) is treated with a corrosion-resistant coating. The coating is crucial for protecting the fasteners and the bottom attachment member itself from the detrimental effects of environmental exposure, such as moisture, chemicals, or abrasive materials commonly encountered in industrial settings. The corrosion-resistant coating significantly extends the service life of the bottom attachment member, ensuring the continued performance and reliability of the device even in harsh operational environments. By preventing corrosion, this feature contributes to the long-term durability and maintenance of the clamping system, thereby reducing the frequency and cost of replacement or repair.

In an embodiment of the present invention, the method of use is a systematic process for ensuring proper alignment and clamping of the upper and lower moulds during the bonding process. The procedure begins with the rotation and alignment of the upper mould relative to the lower mould, ensuring precise positioning for optimal bonding. This alignment ensures that the moulds are correctly oriented, facilitating uniform pressure distribution across the mating surfaces during bonding. Once the moulds are properly aligned, the clamping pin (303), integrated within the assembly, is engaged to secure the relative position of the upper and lower moulds. This engagement effectively locks the moulds in place, preventing any undesired movement or misalignment during the subsequent clamping operation.

The hydraulic cylinder is then actuated to apply a controlled clamping force. The application of this force ensures that the moulds remain firmly secured in their aligned position throughout the bonding process. The hydraulic system allows for fine-tuned control of the clamping pressure, ensuring consistent force distribution and avoiding excessive pressure that could lead to mould deformation or failure.

To further ensure uniform compressive force distribution, multiple clamps are employed, spaced at intervals of approximately 2 meters (or as necessary based on the mould size and application). The clamps work in tandem to distribute the compressive force evenly around the periphery of the mould, preventing localized misalignment or pressure variations. The use of multiple clamps guarantees that the bonding process is carried out with uniform pressure, enhancing the quality and consistency of the bond and reducing the likelihood of defects during the moulding process.

In an embodiment of the present invention provides several advantageous features through optional enhancements, each designed to optimize the performance, efficiency, and longevity of the device for clamping blade moulds during the bonding process:
The device incorporates a thermal management system within the actuator housing. The system is specifically designed to regulate the temperature of the actuator assembly during operation, effectively preventing overheating and ensuring consistent performance throughout the clamping and bonding processes. By maintaining an optimal operating temperature, the thermal management system helps preserve the functionality of the actuator, thereby enhancing overall operational efficiency. The temperature regulation ensures that the actuator operates within its designed parameters, minimizing the risk of malfunction and maximizing the device's reliability during extended use. The device further includes a pressure-regulating Valve integrated into the actuator cylinder. The valve is designed to maintain the compressive force within a specified range, preventing over-pressurization. By ensuring that the applied force remains within optimal limits, the pressure-regulating valve protects the blade moulds from excessive stress and potential damage. The precise control of the compressive force enhances the accuracy and effectiveness of the bonding process, ensuring that the moulds are properly secured without compromising their integrity.

In an embodiment of the present invention, Figures 1 and 1A illustrate the device for the clamping of blade moulds during the bonding process . Figure 1 presents a side view of the actuator assembly (400) in operation during the rotation procedure. The actuator assembly (400) consists of the actuator cylinder (401), actuator arm (402), and their rotary actuator (403). This configuration facilitates the rotation and alignment of the mould halves during the bonding process. Figure 1A provides a 3D view of the device, demonstrating the function of the pneumatic cylinder (600) as it passes through the system after the actuator assembly has completed its rotation. This sequential action allows for the efficient clamping and alignment of the mould components. Both Figures 1 and 1A also show the cover mechanism (), which encloses and protects the various components of the clamping and rotating systems. The device features an integrated clamping assembly designed to securely hold the upper (301) and lower (302) halves of the mould in precise alignment during the manufacturing process. The actuator assembly (400) is positioned on the bottom face (302) of the mould, while the connector part (300), integral to the clamping mechanism (), is mounted on the top face (301) of the mould. This configuration ensures stable alignment and secure fastening between the mould halves.

The second embodiment of the actuator assembly (400), as illustrated in Figure 1, incorporates a support arm (403) that plays a critical role in the precise and continuous rotation of the actuator arm (402) throughout the entire clamping and bonding process (). The support arm (403) is operatively connected to the first end of the actuator arm (402), providing controlled rotational motion that enables the actuator arm to facilitate precise alignment, retraction, and extension of the actuator arm (402) in response to the operation of the actuating cylinder (401) and the overall clamping mechanism. The continuous rotation allows for fine control over the positioning of the top part (200) and bottom part (100) of the moulds, ensuring that the upper and lower moulds are aligned with high precision during the bonding process (). Furthermore the actuator assembly (400) incorporates that ensures coordination between the support arm (403) and the hydraulic system of the clamping pin (303). The support arm (403) is configured with one end fixed to the top main member (201) and the opposite end secured to the actuator assembly (400), functioning as a stabilizing component to restrict rotational movement. The arrangement effectively limits over-rotation, thereby protecting the actuator arm (402) and its associated mechanical components from damage resulting from excessive rotational forces encountered during operational cycles. The integration allows the rotation of the actuator arm (402) to be timed precisely with the extension or retraction of the actuator cylinder (401). As a result, the rotational movement is effectively integrated with the application of compressive forces, ensuring optimal distribution of force and perfect alignment of the mould halves during the bonding process.

The interaction between the actuator assembly (400) on the bottom face (302) and the connector part (300) on the top face (301) enables the efficient closure of the mould under hydraulic actuation. The device further includes a rotating mechanism to align the upper mould relative to the lower mould, a clamping pin (303) mechanism to lock the mould halves in place, and a hydraulic system that actuates the clamping pin (303)s, applying controlled compressive forces to ensure optimal bonding conditions.

In another embodiment of the present invention, as illustrated in Figure 2, 2A, and 2B the actuator assembly (400) remains in an open condition while the top face (301) of the mold rotates (700) and moves into position over the bottom face (302). The design allows for the independent rotation of the top face (301), ensuring that the clamping mechanism () does not interfere with the movement of the mold halves during alignment. The actuator assembly (400) is configured to remain disengaged or in an open state until the top face (301) is properly positioned, at which point the clamping action can be engaged to secure the mold halves together. Clamping mechanism ensures smooth operation and precise alignment throughout the molding process. Furthermore the bottom main member (101) is securely attached to the actuator housing (103) using bolts, ensuring a stable and rigid connection. This bolted attachment (500) provides structural integrity and facilitates the proper functioning of the actuator assembly (400).

In another embodiment of the present invention, as illustrated in Figure 3, and 3B when the top part (200) of the mold is placed over the bottom part (100), the connector part (300) aligns precisely with the slots (104) of the actuator assembly (400). This alignment ensures that the connector part (300) fits securely into the slots (104) of the actuator assembly (400), facilitating accurate engagement and stable positioning of the mold halves. The clamping mechanism () is designed to guide the connector part (300) into the slots (104) with high precision, allowing for seamless integration and ensuring the molds are securely clamped together for the molding process.

In another embodiment of the present invention, as illustrated in Figure 4A, 4B, and 4C the top main member (201) is positioned over the bottom main member (102), the clamping operation is initiated through actuator cylinder (401) actuation. The hydraulic cylinder lever (600) applies pressure to the connector part (300), which in turn exerts force on the top main member (201), securely holding it against the bottom main member (102), This hydraulic-driven (600) clamping mechanism () ensures a strong and consistent clamping force, effectively maintaining the alignment and integrity of the mold halves during the manufacturing process. The hydraulic system provides precise control over the clamping pressure, ensuring optimal performance and mold stability.
