[0121] Working principle: When the present invention is in use, first, it is necessary to pre-adjust the device according to the sizes of the circuit board and the transmitting end:

[0122] First, rotate the first adjusting screw 205 and the second adjusting screw 502 with tools to adjust the distances between the end block 202 and the circular plate 501 and the support base 201 and the cross slide rail 402, so as to change the positions of the circular plate 501 and several rollers 204;

[0123] Rotate the two first fixing screws 110 to enable the sleeve rod 109 to slide inside the sleeve 108, so as to adjust the positions of the shafts at the ends of the first fixing column 306 connected to the ends of the two sleeve rods 109 and the second connecting arm 405. Subsequently, rotate the first fixing screws 110 again to fix the sleeve rod 109 and the sleeve 108 together;

[0124] Rotate the two second fixing screws 606 to enable the moving column 605 to slide inside the moving slide rail 604, so as to adjust the position of the connective bracket 607 connected to the moving column 605, so that the clamps 608 on the connective bracket 607 can clamp welding wires with various diameters, and in cooperation with the opposite movement of the two moving slide rails 604, the clamps 608 can be adjusted according to the distance between the two welding wires for use;

[0125] Rotate the third fixing screws 610 to enable the arc-shaped moving cylinder 609 to slide on the connective bracket 607, and further adjust the distance between the arc-shaped moving cylinder 609 and the connective bracket 607, so as to facilitate the limitation of welding wires with various lengths;

[0126] The telescopic movement of an electric cylinder 106 drives the movement of the first fixed column 306 connected to its end. The movement of the first fixed column 306 drives the movement of the moving block 305 connected to it. The movement of the moving block 305 drives the movement of the rectangular block 309 on the sliding rod 307 connected to it. When the moving block 305 moves, it drives the deflection of the first connecting arm 304 connected to it. The deflection of the first connecting arm 304 drives the rotating arm 303 connected to it to deflect around the first central axis 302, and then drives the deflection of the first connecting arm 304 connected to its other end. The moving block 305 on the first fixed column 306 connected to the first connecting arm 304 moves accordingly, thereby adjusting the positions of the two moving blocks 305 so that when the rectangular block 309 moves, the arc-shaped arm 311 thereon can contact the outside of the circuit board;

[0127] The rotation of the one-way screw rod 103 is driven by the first motor 104, and the movement of the one-way screw rod 103 drives the movement of the moving seat 105, thereby adjusting the distance between the moving seat 105 and the base 102 so that the welding wire at the transmitting end can move to the welding point.

[0128] Subsequently, the transmitting end and the circuit board are correctly placed on the top of the circular plate 501 and a plurality of rollers 204 respectively, and the two welding wires of the transmitting end can be located between two groups of jigs 608 distributed in a staggered manner;

[0129] The movement of the moving end of another electric cylinder 106 drives the movement of the L-shaped folding plate 107. The movement of the L-shaped folding plate 107 drives the movement of the two sleeves 108 rotatably connected thereto. The movement of the sleeves 108 drives the movement of the sleeve rods 109. The movement of the two sleeve rods 109 drives the movement and deflection of the first connecting arm 304 and the second connecting arm 405 connected to them respectively;

[0130] The movement and deflection of the first connecting arm 304 drive the rotating arm 303 connected to it to deflect around the first central axis 302, and then drive the deflection of the first connecting arm 304 connected to its other end. The moving block 305 on the first fixed column 306 connected to the first connecting arm 304 moves accordingly, so that the two moving blocks 305 can approach each other. The movement of the moving block 305 drives the sliding rod 307 and the first limiting wheel 308 at its end to slide inside the rectangular slide rail 301, thereby making the rectangular blocks 309 sliding on the sliding rods 307 of the two moving blocks 305 approach each other;

[0131] The arc-shaped arm 311 rotatably arranged on the rectangular block 309 moves accordingly. The movement of the arc-shaped arm 311 drives the movement of the first roller 313 thereon. The first roller 313 close to the limiting column 315 contacts the outside of the circuit board. As the first roller 313 continues to move, one side of the arc-shaped arm 311 contacts the limiting column 315. During this process, the arc-shaped arm 311 deflects and stretches the connecting spring 314. The deflection of the arc-shaped arm 311 drives the deflection of the first roller 313 at its other end to contact the other side of the circuit board for clamping and limiting;

[0132] The movement and deflection of the second connecting arm 405 drive the deflection of the cross arm 404 connected thereto. The second connecting arm 405 connected to the remaining end of the cross arm 404 deflects and moves accordingly, causing the second fixing posts 406 at the other ends of the four second connecting arms 405 to slide along the cross slide rail 402. The second rollers 408 on the second fixing posts 406 move accordingly, enabling the four second rollers 408 to clamp and fix the transmitting end.

[0133] The second motor 603 is used to drive the rotation of the bidirectional screw 602. The rotation of the bidirectional screw 602 drives the two moving slide rails 604 thereon to move towards each other. The movement of the moving slide rails 604 drives the connection bracket 607 thereon to move, enabling the clamp 608 and the arc-shaped moving cylinder 609 on the connection bracket 607 to clamp and limit the welding wire.

[0134] Finally, the welding equipment 7 is used to weld the welding wire of the transmitting end and the welding point on the circuit board, thereby realizing the automatic welding operation of the wireless charging circuit board. Subsequently, through reverse operation, the clamping of the wireless charging circuit board can be released, and the welded wireless charging circuit board can be removed. Then, the transmitting end and the circuit board to be welded are placed again for the next welding operation.

[0135] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
