[0023] Specifically, refer to Figure 1 The clamping component 330 includes a clamp 380, each of which includes a first clamp 381 and a second clamp 382. The first clamp 381 and the second clamp 382 are respectively provided with a positioning groove for accommodating a half slot of a battery cell.

The clamping component 330 also includes a clamping driving component for driving the first clamp 381 to rotate toward the second clamp 382 at a set angle so that the packaging shell 920 forms a pre-crease. The pre-crease is the center line of the packaging shell 920. By forming the pre-crease first, it is convenient to clamp the packaging shell 920 in the subsequent process. In specific applications, during pre-folding, a movable pressing plate can also be set to press the packaging shell 920 on the second clamp 382, ​​so that the pre-folding effect is better.
