Background

In production, many products are transported and transported on pallets. For example, in a lithium battery module assembly process, the end plates of the battery module are loaded into a tray and conveyed to a setting station by a conveying assembly.

In order to improve the transfer efficiency of the trays, a plurality of trays (which may be provided with parts such as the end plates of the battery modules described above) are generally conveyed after being vertically stacked to form a tray group.

Currently, the automatic folder opening mechanism includes: the tray conveying mechanism, the lifting assembly in the vertical direction of the tray conveying mechanism and the tray cutting mechanism positioned above the lifting assembly, wherein the tray cutting mechanism comprises a clamping mechanism which can horizontally and oppositely stretch. The lifting assembly tray set is lifted upwards, when a second tray which starts counting from the lifting assembly is aligned to the clamping mechanism of the tray cutting mechanism, the lifting assembly stops, the clamping mechanism stretches out oppositely and clamps the aligned second tray, the first tray which starts counting from the lifting assembly is lifted by the lifting assembly to move downwards, and the first tray falls onto the tray transmission mechanism to finish the primary splitting action.

The clamping mechanism clamps the trays from two sides of the tray set, so that the trays are easy to damage.
