[0002] Rectangular pallets are a common material carrying tool, widely used for the transportation and storage of materials in automated production lines. During the production, transportation and warehousing process, the rectangular pallets at the bottom of the materials need to be replaced on time to meet the requirements of different usage scenarios and problems such as pallet aging. However, since the rectangular pallet is located at the bottom of the material, if the material is too heavy, the entire replacement process will become relatively complicated and cumbersome. The current common method is to use a forklift to transfer materials from the old pallet to the new pallet, or to use a pallet changer. Using a forklift to replace the pallet is not only time-consuming and labor-intensive, but also requires a large space, and the working process is not continuous enough, resulting in low overall work efficiency. Existing pallet switches basically use the method of flipping materials to complete pallet replacement.
