[0052] The working principle and use process of this utility model:
[0053] First, the operator holds the circuit board and places it on the top of the spot welding table 3, and at the same time aligns the welding point of the chip capacitor on the circuit board with the bottom end of the spot welding rod 12, and then starts the drive motor 501, so that the drive shaft 502 drives the push rod 503 to rotate, so that the inner wall of the push rod 503 generates a thrust on the outer surface of the connecting rod 504, pushing the connecting rod 504 to move along the inner surface of the slide groove 401 with the square frame 405 and the slider 402. At this time, the extension block 403 fixedly connected to the slider 402 will move with the roller brush 404, and then the operator starts the power motor 6, so that the rotating shaft 7 drives the roller brush 404 to rotate, thereby cleaning the dust at the welding point of the chip capacitor on the circuit board to prevent the accumulation of dust from affecting the welding effect of the chip capacitor pins, causing poor contact during subsequent use.
[0054] When the cleaning is completed, the operator starts the drive motor 501 again to reset the roller brush 404 and stop the power motor 6, then places the chip capacitor at the welding position on the circuit board and starts the pneumatic cylinder 9, so that the movable block 10 moves downward with the round block 11 and the spot welding rod 12. When the bottom end of the pressure ring 16 contacts the chip capacitor, the spot welding rod 12 continues to move downward. At this time, the pressure ring 16 will move the circular ring 14 up along the inner surface of the cylinder 13 and compress the spring 15. Under the restoring action of the spring 15, the circular ring 14 and the pressure ring 16 will be forced to reset, so that the chip capacitor can be compressed, thereby preventing the chip capacitor from shifting in position during spot welding.
