[0002] In the post-packaging processes of industries such as food, beverage, and daily chemical products, it is often necessary to stack various box pallets arranged alternately. Generally, during processing, packaging, or transportation, materials, packaged or unpackaged items need to be arranged and stacked on pallets according to a certain pattern, and after stacking is completed, they are pushed out to facilitate further packaging or transportation. In the processing of electronic devices, a large number of parts formed by stamping, die-cutting, etc. are involved. After these parts are produced, they need to be placed in corresponding trays for palletizing, packaging, and transportation.

[0003] Currently, traditional electronic spare parts are adsorbed and transported by a manipulator after the production inspection process and placed in trays for palletizing, packaging, and transportation for shipment. However, when the manipulator directly grabs parts at the previous inspection station, it may grab parts of different specifications and models, and parts of different models need to be palletized into corresponding trays respectively. Usually, the manipulator directly grabs and transports them uniformly into the trays, and then manual sorting is carried out to pick out parts of different specifications to ensure that the parts in the same tray are of the same specification. However, this operation is slow, inefficient, prone to errors, wastes manpower, and is difficult to achieve the goal of automated intelligent manufacturing production. Summary of the Utility Model
