In particular, since the lifting plate 23 can move relative to the mounting plate 21, when the clamping mechanism 1 is driven to approach the battery core and the battery core is offset from the predetermined position, if the clamping mechanism 1 contacts the battery core, the battery core will apply a reaction force to the clamping mechanism 1, so that the clamping mechanism 1 moves towards the side away from the battery core, that is, the lifting plate 23 moves towards the mounting plate 21, thereby realizing that the first sensing element 25 is sensed by the first sensor 24. The first sensor 24 is in communication connection with the moving mechanism, and the first sensor 24 can transmit signals to the moving mechanism so that the moving mechanism returns to an initial position, namely, the clamping mechanism 1 is actively driven to keep away from the battery cell, so that the battery cell transferring device is ensured not to damage the battery cell.

To enhance the carrying capacity of the cell transfer device, the clamping mechanism 1 comprises a plurality of groups of clamping plate assemblies, each group of clamping plate assemblies comprises two clamping plates 11 which are oppositely arranged, so that one group of clamping plate assemblies can clamp one cell.

Referring to fig. 3, each clamping plate 11 includes a plurality of sub-clamping plates, one sub-clamping plate is detachably connected in one sliding slot 121, and the plurality of sub-clamping plates are spaced apart along the extending direction of the sliding slot 121. In this embodiment, one clamping plate 11 includes two sub clamping plates, so that stable clamping of the soft package battery cells with longer length can be realized, and the soft package battery cells with different sizes can be adapted by adjusting the relative positions of the sub clamping plates on the adapter plate 12.

In addition, whether the battery cell is clamped according to a predetermined gesture is also an important factor for ensuring the stable clamping of the battery cell and no damage, so the clamping plate 11 is also provided with a position sensor 26. When the battery cell is clamped at the preset position, the position sensor 26 is flush with the upper surface of the battery cell, and whether the battery cell is clamped at the preset gesture can be obtained by observing whether the upper surface of the battery cell is at the preset position.
