BACKGROUND OF THE INVENTION

[0002] Rust removal is essential for maintaining the integrity, functionality, and appearance of metal surfaces. Accumulated rust weakens structural components, reduces efficiency, and compromises the overall durability of metal objects, leading to potential failures or costly replacements. Effective rust removal preserves the strength of metal surfaces while enhancing their longevity and performance. Ensuring accurate detection of rust and maintaining an optimal removal distance is crucial for achieving thorough and efficient rust elimination. Inconsistent rust removal results in uneven surface treatment, residual corrosion, and increased effort for rework, diminishing the effectiveness of the process. Adapting to varying surface conditions while maintaining precision enhances the efficiency of rust removal, reducing material deterioration and extending the lifespan of metal components. Reliable rust removal methods contribute to improved safety, structural stability, and reduced maintenance costs, ensuring that metal surfaces remain in optimal condition for extended use.

[0003] Traditional rust removal methods often rely on manual tools and techniques that require significant physical effort and user estimation. These approaches present several drawbacks. For example, conventional methods lack the precision needed to accurately detect rust on varying surface textures, leading to incomplete removal and residual corrosion. Furthermore, manual techniques do not provide continuous monitoring of the removal process, resulting in inconsistent treatment and the need for repeated applications. The absence of advanced features, such as real-time distance monitoring or automated rust detection, increases the likelihood of uneven surface restoration and excessive material removal. Additionally, traditional methods fail to ensure optimal efficiency, particularly in scenarios where accuracy and thorough rust elimination are essential. To achieve effective and consistent results, adopting solutions that enhance detection accuracy and provide continuous monitoring is crucial for improving the quality and efficiency of rust removal.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0018] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0019] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to a rust removal assistive device that assists in the removal of rust from surfaces, by providing an adjustable means that automatically adapts to a user’s hand size, effectively positions rust-removing elements, and collects airborne debris, ensuring efficient and safe rust removal.

[0021] Referring to Figure 1, an isometric view of a rust removal assistive device is illustrated, comprises of an L-shaped hollow cylindrical body 101 configured with a handle 102, an artificial intelligence-based imaging unit 103 installed on the body 101, a motorized expandable pulley mechanism 104 installed within the handle 102, a DC (Direct Current) motor 105 installed within the body 101 and attached to a circular plate 106, plurality of pneumatic pins 107 installed on the plate 106, a motorized suction unit 108 installed within the body 101, and a dual axis slider 109 installed over the plate 106, a waste container 110 integrated with said suction unit 108.

[0022] The proposed device herein includes an L-shaped hollow cylindrical body 101 configured with a handle 102 that is gripped by a user. The user grips and positions the body 101 over a rusted surface for rust removal. To initiate the process of rust removal, a push button associated with the device is pressed by the user for the activation of the device. The button is typically connected to the device's internal circuitry, allowing the user to activate or deactivate the device through a simple press.

[0023] When the button is pressed, leads to completing a circuit, and sending an electrical signal to an inbuilt microcontroller linked with the device. The microcontroller receives the signal from button and executes instructions to initiate the working of the device. The microcontroller is pre-fed with a defined set of instructions to further actuate the other components to remove the rust from the surface.

[0024] The microcontroller activates an artificial intelligence-based imaging unit 103 installed on the body 101 work in sync with an ultrasonic sensor integrated within the handle 102 to determine dimension of the user’s hand. The imaging unit 103 includes a camera that captures images of the user’s hand to gather comprehensive visual information. The ultrasonic sensor emits sound waves measure distances and detect variations in the user’s hand. The microcontroller processes the visual data from the imaging unit 103 and combines with the distance measurements from the ultrasonic sensor, to determine dimension of the user’s hand.

[0025] Based on the determined dimensions, the microcontroller actuates a motorized expandable pulley mechanism 104 installed within the handle 102 to expand/contract to change dimension of the handle 102 for enabling the user to comfortable grip over the handle 102. The expandable pulley arrangement works through pulley and tensioning mechanism 104 controlled by the microcontroller. The pulley consists of a pulley wheel configured with extendable linear actuators on the outer portion of the wheel.

[0026] The linear actuators expand through the hydraulic unit that includes an oil compressor, hydraulic cylinder, solenoid valves and piston which works in collaboration to aid in extension and retraction of handle 102. When the actuator is activated, causing to either extend or retract the wheel leading to change the pulley’s position. As the pulley moves, adjusts the diameter of the connected disc by either increasing or decreasing the spacing between the actuators, hence adjusting the handle 102 to position the device in proximity to the rusted surface.

[0027] The body 101 is installed with an IR (Infra-red) sensor to detect distance of the rust surface relative to the body 101. The IR (Infra-red) sensor works by emitting infrared light from a transmitter, which travels toward the rusted surface. When the emitted light hits the rusted surface, the light reflects back to a receiver integrated into the sensor. The sensor then measures the time taken for the light to return. Based on this time, the sensor calculates the distance between the sensor and the rust surface. This information is then sent to the microcontroller to detect distance of the rust surface relative to the body 101.

[0028] Based on the detected distance, the body 101 is installed with a circular plate 106 having a DC (Direct Current) motor 105 attached. The DC (Direct Current) motor 105 works by using electrical energy to produce rotational motion. When the microcontroller sends an electrical signal to the motor 105, current passes through the motor's armature (rotating part) and magnetic field. This causes the armature to rotate due to the interaction between the magnetic field and the electric current, creating torque. The rotation of the armature is transferred to the circular plate 106 attached to the motor 105, causing it to rotate. The motor's speed and direction of rotation is controlled by adjusting the amount of electrical current supplied to the motor 105, which is managed by the microcontroller.

[0029] Plurality of pneumatic pins 107 are installed on the plate 106 to extend and rotate for removing the rust from the rusted surface effectively. Pneumatic pins 107 operate by using compressed air to extend and retract for removing the rust from the rusted surface effectively. When air pressure is introduced into the pneumatic cylinder connected to the pins 107 to push the pin outward for effectively extending the pins 107 to form exert force and remove rust. To retract the pins 107, the air pressure is released to allow a spring mechanism 104 to pull the pin back into its housing, hence, changing the structure of the pins 107 as per requirement.

[0030] The pins 107 are mounted over a dual axis slider 109 installed over the plate 106, is activated by the microcontroller to enable controlled movement of the pins 107 along horizontal and vertical directions. The helps to precisely position the pins 107 over the rusted surface for effective rust removal. The dual-axis slider 109 consists of two linear rails or tracks that are oriented at right angles to each other (horizontal and vertical). The pins 107 are mounted on a carriage that moves along these rails. The movement is driven by motor 105 that control the position of the carriage both along the horizontal axis (side to side) and the vertical axis (up and down). The microcontroller sends the signals to the motors 105, instructing them to move the carriage along the horizontal and vertical tracks for removing rust.

[0031] In case the microcontroller via the imaging unit 103 detects small rusted areas, the microcontroller actuates the particular pin to extend over the area to perform rust removal operation.

[0032] The body 101 is installed with a force sensor, linked to the microcontroller to monitor an amount of pressure applied by the pins 107 on the rust surface. The force sensor consists of components such as strain gauges to measure force through changes in electrical resistance when deformed due to applied pressure. As the pins 107 apply the pressure, the force sensor captures the pressure applied and converts it into an electrical signal. This signal is then transmitted to the microcontroller, which interprets the force exerted.

[0033] In accordance to the detected pressure, the microcontroller adjusts rotation speed of the DC motor 105 to prevent excessive force application and ensure uniform rust removal.

[0034] During the process of rust removing, a dust particle sensor is installed on the body 101 to detect a concentration of airborne rust and debris. Dust particle sensor use an optical method for detecting particles. The sensor consists of a light source that illuminates the air stream. When dust particles are present in the surroundings, the light is scattered. The photodetector in the sensor measures the amount of scattered light. The amount of scattered light correlates with the number of particles and their sizes. The sensor processes this signal to determine the concentration of dust particles in the air.

[0035] Based on the detection, the microcontroller activates a motorized suction unit 108 installed within the body 101 to create vacuum pressure to collect and dispose the airborne rust and debris within a waste container 110 integrated with the suction unit 108. The suction unit 108 works by creating a vacuum pressure to draw in and collect airborne rust and debris created during the rust removal process.

[0036] When activated by the microcontroller, an electric motor 105 powers a fan or impeller inside the suction unit 108. As the fan spins, air is pulled into the suction unit 108 through an intake, causing a reduction in air pressure inside. This creates a vacuum effect, drawing airborne particles, such as rust and debris, from the surrounding environment. These particles are then directed into a waste container 110 integrated within the suction unit 108. The vacuum pressure ensures that debris is efficiently collected and contained for disposal, preventing dispersion back into the air during the rust removal process.

[0037] Furthermore, a battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the device.

[0038] The present invention works best in the following manner, where the L-shaped hollow cylindrical body 101 with the handle 102, which is gripped by the user to position the device over the rusted surface. Upon pressing the activation button, the microcontroller receives the signal and activates the artificial intelligence-based imaging unit 103 and the ultrasonic sensor to determine the user’s hand dimensions. This data is used to control the motorized expandable pulley mechanism 104 within the handle 102, allowing the user to achieve a comfortable grip. The IR sensor installed on the body 101 detects the distance from the rusted surface, sending the information to the microcontroller. The microcontroller then activates the DC motor 105 to rotate the circular plate 106, powering pneumatic pins 107 mounted on the dual-axis slider 109. The slider 109 enables precise movement of the pins 107 along both horizontal and vertical axes, ensuring effective rust removal. The microcontroller further monitors the force applied by the pins 107 on the rusted surface via the force sensor and adjusts the motor 105 speed to prevent damage. Simultaneously, the dust particle sensor detects airborne rust and debris. Based on the data, the microcontroller activates the motorized suction unit 108, which creates a vacuum to collect the debris into the integrated waste container 110, ensuring a clean work environment. The combination of these components allows for efficient, precise, and comfortable rust removal while minimizing any risk of damage to the rusted surface or excessive airborne particles.
