Specifically, the loading jaws include a second jaw cylinder 22 and a second clamping plate 23. The two movable ends of the second jaw cylinder 22 are connected to the second clamping plate 23. The first jaw cylinder 1221 drives the first clamping plate to clamp the battery cell 3 for easy transportation to the pallet 121.

[0037] In some embodiments, a material level sensor 24 is disposed on the second clamping jaw cylinder 22 . After the material level sensor 24 detects the battery cell 3 , the second clamping jaw cylinder 22 drives the second clamping plate 23 to stably clamp the battery cell 3 .
