Pallet, battery production line, and control method

A pallet, configured to place a battery cell, the pallet comprising:

• a pallet body, comprising a placement region configured to place the battery cell;
• at least two first position-limiting assemblies, disposed in the pallet body, wherein one part of the first position-limiting assemblies is disposed on one side of the placement region along a first direction, and the other part of the first position-limiting assemblies is disposed on the other side, the first position-limiting assemblies each comprise a first elastic assembly and a first position-limiting block that is movable along the first direction, the first position-limiting block is provided with a first position-limiting surface configured to abut against the battery cell along the first direction and a second position-limiting surface configured to abut against the battery cell along a second direction, the first elastic assembly is disposed in the pallet body, the first elastic assembly comprises a first driving end that is elastically telescopic along the first direction, and the first driving end is in driving connection with the first position-limiting block;
• and
• a second position-limiting assembly, disposed in the pallet body, wherein the second position-limiting assembly is disposed on a side of the placement region along the second direction, the second position-limiting assembly comprises a second position-limiting block that is movable along the second direction, and the second position-limiting block is provided with a third position-limiting surface configured to abut against the battery cell along the second direction;
• wherein the second position-limiting surface and the third position-limiting surface are respectively located on opposite sides of the placement region along the second direction, and the first direction intersects with the second direction.
