Description

Technical Field

[0001] The utility model relates to the technical field related to pallets, in particular to a pallet with a rotating structure. Background Art

[0002] Power battery packs are generally assembled in an assembly line manner. Specifically, after a plurality of individual power batteries are arranged and bound and placed on a pallet, the power batteries are positioned by means of positioning blocks arranged in the front, back, left and right directions of the pallet, and then the pallet is placed on a conveyor belt of a conveyor. The pallet is transported to various workstations by means of the conveyor belt for wiring, welding of wires and assembly of other components. Although existing pallets can meet the use requirements, they are only suitable for positioning power battery packs of a certain length and width, and are relatively not very practical. In addition, when wiring or welding is completed on one side of the power battery pack on the pallet, it needs to be rotated 90° or 180° before wiring or welding is performed on the other side. In the existing method, the pallet is lifted by a lifting device, rotated 90° or 180° and then placed on the conveyor belt. This rotation adjustment method is relatively cumbersome and not easy to operate. Utility Model Content
