The second shaping device 40 includes a telescopic component 32 and a second shaping component 42 connected to the telescopic component 32. This realizes the shaping of battery tabs of different thicknesses during the battery production process, which is convenient to operate and reduces production costs.

[0045] To facilitate understanding, the working principle of this application is further described as follows: For the shaping device for battery tabs, firstly, the thickness of the tab is determined, and according to the thickness of the tab, the corresponding adjustment groove 331F is selected and the adjustment plate 332 is inserted, thereby adjusting the depth of the tab shaping hole 331H to meet the shaping requirements of the tab of the current thickness. In addition, the protrusion distance of the adjusting shaping mechanism 421 can be adjusted by increasing or decreasing the number of adjusting shaping blocks 4211 to further meet the shaping requirements of tabs of different thicknesses.

[0046] Subsequently, during operation, the first shaping device 30 and the second shaping device 40 cooperate, the adapter slot 331G corresponds to the battery cup 50, and the tab is located between the tab shaping hole 331H and the adjusting shaping mechanism 421. The adjusting shaping mechanism 421 cooperates with the tab shaping hole 331H, and under the action of the telescopic component 32, the tab is shaped, which effectively improves the convenience of using the battery tab shaping device and avoids the need to use multiple shaping devices of different specifications to meet the shaping of tabs of different thicknesses, thus effectively reducing production costs.
