Description

Technical Field

[0001] The utility model relates to automation equipment, in particular to a pallet loading and unloading mechanism. Background Art

[0002] Pallets are used to hold parts. For example, in the production process of electric motors, pallets are needed to hold bearings, and then the pallets are transferred to the production process. In the existing technology, workers first manually transport the pallets containing bearings to the designated location of the production process. After the bearings in the pallets are taken out, the workers will transfer the pallets to a place where bearings can be loaded, and the cycle repeats. This transportation method has greatly reduced work efficiency, and workers may also cause the risk of pallets overturning or damaging the pallets or the bearings in the pallets during the transportation process. When a large number of bearings are required, the number of workers will inevitably increase, and multiple workers will shuttle back and forth in the production workshop, causing chaos in the production space.
