[0002] In the prior art, battery cells are transported on logistics lines via pallets. During transportation, the battery cells and pallets will be offset, and the welding positions of the welding plates on which the battery cells are placed will also be offset.

In addition, the pallets and welding plates carrying the battery cells need to be replaced frequently, which invisibly increases the operating costs and also consumes a lot of manpower and material resources.
