[0030] like Figures 1 to 4 As shown, a battery cell bar pressing tool according to an embodiment of the utility model comprises a placement module and a pressing module.

[0031] Specifically, Figure 1~2As shown in Figure 4, the placement module is used to place the bar sheet 4 and the cell cover plate 5 to be pressed. The placement module includes: a column 11, a mounting plate 12 and a placement platform 13. The mounting plate 12 is arranged on the top of the column 11; the placement platform 13 is arranged on the top of the mounting plate 12, and the placement platform 13 is provided with a cell cover plate placement area 131 and two bar sheet placement areas 132, and the cell cover plate placement area 131 and the two bar sheet placement areas 132 are used to place the cell cover plate 5 and the two bar sheets 4 respectively.

[0032] Specifically, Figures 1 to 3 As shown, the clamping module is located on the placement module, and the bar sheet 4 and the cell cover plate 5 on the placement module are clamped. Two welding copper nozzles 3 are provided on the clamping module. The clamping module includes: two positioning columns 21, two clamps 22, a clamping platform 23 and two locking buckles 24. The two positioning columns 21 are arranged on both sides of the placement platform 13; the two clamps 22 are respectively arranged on the outside of the two positioning columns 21; the clamping platform 23 is arranged on the top of the placement platform 13, and two welding ports 231 are provided on the clamping platform 23. Two welding copper nozzles 3 are arranged on both sides of the bottom of the clamping platform 23, and are respectively opposite to the positions of the two welding ports 231; two locking buckles 24 are arranged on both sides of the clamping platform 23.
