Description:FIELD OF THE INVENTION
[001] The present disclosure relates to a fixing-gun system and method for fixing workpiece on an assembling workstation. Particularly, the present disclosure relates to a fixing-gun system that provides a fixing-gun with multiple degree-of-freedom.

BACKGROUND OF THE INVENTION
[002] In continuous production or batch production, an assembling workstation is used that provides ergonomic working posture and hence increases production output. In some assembling workstations, conventional torque-arms are used for holding a fixing gun like a screwing gun. Conventional torque-arm supports a fixing-gun and provides fixing-gun with vertical and horizontal movements. Conventional torque-arms may not provide rotational movement (has zero degree of rotational freedom) to the fixing gun. Thus, the conventional torque-arm can only screw perpendicularly (i.e. screw only at 90 degree) of workpiece, which may result tiresome for user for continuously manually adjusting the vertical and horizontal movements. Alternatively encoders are provided for horizontal and vertical adjustments of the fixing-gun. Known torque-arms are used only for vertical-type of screw-guns. More further, conventional screw-guns do not have holders for holding screw-guns in different angles.

DETAILED DESCRIPTION OF THE INVENTION

[008] Referring now to the drawings, Figures 1 to 8, where the present invention is generally referred to with numeral (100), it can be observed that a fixing-gun-system (100) for fixing workpiece (01) on an assembling workstation (02), in accordance with an embodiment, is provided which includes a workstation-platform (10), a control-unit (20), a torque-arm (30), and a gun-holder (40).

[009] The present invention relates to a fixing-gun system (100) designed for ergonomically screwing workpieces (01) on an assembling workstation (02). The fixing-gun system (100) is particularly suitable owing flexibility in movement and adjustment of the fixing gun (50).

[010] The fixing-gun system (100) includes a workstation-platform (10), which serves as the base for mounting the various components of the fixing-gun system (100). The fixing-gun system (100) includes the control-unit (20), which manages the operation and movement of the fixing-gun system (100), ensuring precision and ease of use during the assembly process.

[011] The torque-arm (30) is a key component of the system, that allows multiple (horizontal, vertical and angular) degrees of freedom for adjusting the fixing-gun (50). The torque-arm (30) is composed of a vertical-stand (31) that is connected to the surface (10a) of the workstation platform (10). The vertical-stand (31) is angularly adjustable, allowing the fixing-gun system (100) to accommodate different angles of operation. A transverse-arm (32) is transversely connected to the vertical-stand (31), enabling the horizontal movement of the fixing gun (50). This transverse-arm (32) is vertically adjustable on the vertical-stand (31), allowing for both vertical and angular adjustments to be made with ease. To enhance precision, a horizontal-distance-sensor (33) is disposed on the transverse-arm (32) and a vertical-distance-sensor (34) is located on the vertical-stand (31). The horizontal-distance-sensor (33) and the vertical-distance-sensor (34) sensor work in conjunction to provide accurate measurements and feedback regarding the positioning of the fixing-gun (50) during operation.

[012] In one embodiment, the vertical-stand (31) is further defined by a base (31a), which is securely affixed to the surface (10a) of the workstation platform (10). A mounting-plate (31b) is provided with a bush (31bi) which is inserted into the base (31a) to provide smooth angular adjustments. The mounting-plate (31b) also includes a left-hand-stopper (31c) and a right-hand-stopper (31d), which limit the angular movement of the vertical-stand (31) and provide precise control over the angle at which the fixing gun operates. In one embodiment, the angular movement of the vertical-stand (31) is performed manually. A pair of vertical-rods (31e) is connected to the left-hand-stopper (31c) and the right-hand-stopper (31d). The linear-bearing (31f) is fitted with the vertical-rods (31e) to enable smooth angular adjustments. An enclosing-unit (31g) encloses the linear-bearing (31f) and vertical-rods (31e), providing protection and ensuring stability during operation.

[013] The transverse-arm (32) is also defined by a horizontal-extendable-arm (35), which is adjustable and fitted with adjustment-holes (35a) to allow for extension and retraction as needed. The horizontal-extendable-arm (35) is connected to the vertical-stand (31) to provide horizontal adjustability. Additionally, a pair of horizontal-rods (36) is connected to the horizontal-extendable-arm (35), further enhancing the stability and precision of the fixing-gun system (100).

[014] The gun-holder (40) is mounted on the transverse-arm (32) and is responsible for securely holding the fixing gun (50) while allowing it to pivot and adjust its position. The gun-holder (40) consists of a pivot-block (41), which connects it to the transverse-arm (32) and provides pivotal adjustment. A sensing-bracket (42) is connected to the pivot-block (41), allowing the horizontal-distance-sensor (33) and vertical-distance-sensor (34) to reference and measure distances accurately. The gun-holder (40) further includes a first-holder (43) and a second-holder (44), which are connected by a spacer-rod (45). The spacer-rod (45) is secured by fasteners (46), ensuring stability and precise positioning of the fixing gun (50) between the first-holder (43) and second-holder (44).

[015] The fixing gun (50) itself is positioned between the holders (43, 44) and is capable of various movements, including pivotal adjustment via the pivot-block (41), horizontal adjustment by the horizontal-distance-sensor (33), vertical adjustment via the vertical-distance-sensor (34), and angular adjustment through the vertical-stand (31). These features provide comprehensive adjustability, allowing the system to efficiently fix workpieces at various angles and positions on the workstation.

[016] Thus, the fixing-gun system (100) offers full adjustability for fixing workpieces (01) on an assembling workstation (02), with precise control over horizontal, vertical, angular, and pivotal movements, ensuring an ergonomic and efficient assembly process.

[017] The present disclosure also discloses a method, for fixing workpiece (01) on an assembling workstation (02), in accordance with one embodiment. The best-method initiates with providing the fixing-gun-system (100) which is defined with the workstation-platform (10), the control-unit (20), the torque-arm (30) and the gun-holder (40). The torque-arm (30) is defined with the vertical-stand (31) in connection with the surface (10a) of the assembling workstation (10), the transverse-arm (32) which is transversely connected to the vertical-stand (31), the horizontal-distance-sensor (33) is disposed on the transverse-arm (32) and the vertical-distance-sensor (34) is disposed on the vertical-stand (31). The fixing-gun-system (100) as discussed in details in above paragraphs are not repeated for undesired repetition.

e. fastening the fasteners (46) to the spacer-rod (45) with the first holder (43) and the spacer-rod (45) with the second-holder (44).

[019] In the next step, the vertical-stand (31) is adjusting angularly. In one embodiment, the vertical-stand (31) is manually adjusted by angularly rotating the vertical-stand.

[020] In the next step, the control-unit (20) controls movement of the transverse-arm (30) on the vertical-stand (31). The control-unit (20) compares prefed fixing point with position of the vertical-distance sensor (34).

[021] In the next step, the control-unit (20) controls movement of the gun-holder (40) on the traverse-arm (32). The control-unit (20) compares prefed fixing point with position of the horizontal-distance sensor (34).

[022] The control-unit (20) continuously determines the real-time position of the gun-holder (40) with respect to the workpiece (01) and in event if the gun-holder (40) is at the defined location then the control-unit (20) initiates instructions to start the operation of the fixing-gun (50) and in event if the gun-holder (40) is not at the defined location then the control-unit (20) initiates instructions to not-to-start the operation of the fixing-gun (50).
