In the embodiment of the present application, the clamping portion 2323 is lowered by the combined action of the elastic member 2321b and the descending section of the rail 222. The movable roller 2322 and the clamping portion 2323 are both mounted on the slider. The movable roller 2322 moves along the track 222, and when the movable roller 2322 ascends or descends along the track 222, the slider is driven to ascend or descend, so as to drive the clamping part 2323 to ascend or descend. When the movable roller 2322 ascends along the rail 222, the slider compresses the elastic member 2321b, so that the elastic member 2321b is in a compressed state. When the movable roller 2322 descends along the track 222, the compression action of the slider on the elastic member 2321b is continuously reduced, and the elastic member 2321b gradually recovers elastic deformation. The application of the elastic member 2321b makes the structure of the second clamp 232 simple, and the change of the elastic deformation of the elastic member 2321b easily realizes the function of the clamping part 2323. Specifically, the elastic member 2321b may be a spring in an embodiment of the present application.

Referring to fig. 3, the first sliding portion 2321d slides up and down along the sliding rail 2321c, and the second sliding portion 2321e is connected to the first sliding portion 2321d, so that the first sliding portion 2321d drives the second sliding portion 2321e to slide up and down along the sliding rail 2321 c. Since the movable roller 2322 and the clamping portion 2323 are respectively located at two opposite sides of the slider, the second sliding portion 2321e is configured to be sleeved on the mounting plate 2321a, one side of the second sliding portion 2321e is provided with the movable pulley, and the other side of the second sliding portion 2321e is connected with the first sliding portion 2321d provided with the clamping portion 2323. More specifically, according to the design of the rail 222, the movable roller 2322 is located higher than the position of the clamping portion 2323, so that when the movable roller 2322 ascends along the rail 222, the clamping portion 2323 and the first clamp 231 are gradually opened from the closed state. In this case, the second sliding portion 2321e is disposed above the first sliding portion 2321d, and thus the elastic member 2321b is disposed between the second sliding portion 2321e and the mounting plate 2321 a.

When the tab clamp 230 is rotated to the spot welding mechanism 300, the upper pin welds the positive tab and the lower pin welds the negative tab, and both pins complete the weld by cylinder action. Finally, the discharging mechanism 400 is used for discharging the product after spot welding. The spot welding apparatus of the present application can be commonly used for various types of lug welding by replacing the lug fixture 230.
