Similarly, the second positioning groove 850 is used for contacting and limiting the full welding head of the full welding machine 63, so that the full welding machine 63 can be accurately positioned, the full welding machine 63 cannot shift in the welding process, the stability of the full welding machine 63 is ensured, the full welding machine 63 can accurately fully weld the explosion-proof sheet on the corresponding positioning piece 90 on the turntable and the battery cover plate, and the full welding quality of the full welding machine is ensured.
The number of the first positioning grooves 830 in each spot welding positioning portion 83 and the number of the second positioning grooves 850 in each full welding positioning portion 85 may be one or more. The number of the first and second positioning grooves 830 and 850 may be determined according to the number of the battery end caps on each positioning member 90. In the present embodiment, the number of the first positioning grooves 830 in the spot welding positioning portion 83 and the second positioning grooves 850 in the full welding positioning portion 85 is two.
In addition, spot welding holes 832 on spot welding positioning portion 83 are distributed along the circumferential direction and are matched with the shape of the explosion-proof sheet, and spot welding holes 832 are arranged along the circumferential direction of the outer contour of the explosion-proof sheet.

In particular, in order to ensure that the position of the rotary disc is relatively fixed in the welding process, the battery cover and the explosion-proof sheet are not easy to displace due to the shaking of the rotary disc. In view of this, the spot welder 53 may further include an auxiliary positioning device for positioning the turntable. The auxiliary positioning device includes a first positioning plug-in (not shown) and a second positioning plug-in (not shown), the first positioning plug-in is disposed on the spot welding machine 53, and a first positioning hole 84 for the first positioning plug-in is disposed at the spot welding positioning portion 83 on the positioning plate 80.
