Technical Field

[0001] The utility model relates to a goods picking mechanism, in particular to a goods picking mechanism for a storage shelf. Background Art

[0002] Warehouse shelves are devices used for storage. With the continuous development of related industries, the functions of warehouse shelves have been continuously expanded to packaging, transportation, loading and unloading, sorting, information management, etc. In the traditional logistics warehousing model, in order to meet order requirements, workers are required to push material carts to different locations in the warehouse to pick up different goods, that is, "people arrive at the goods". This leads to high labor intensity and low efficiency in storing and retrieving goods.

[0003] However, in recent years, the intelligence and automation of warehousing and logistics have developed rapidly. In order to reduce the workload of workers and enable workers to quickly and efficiently classify and store various goods, and to reduce the time of goods in the storage and picking process to a certain extent, the Chinese patent document with application number CN201911275610.18 discloses an automatic picking device, which specifically discloses a clamping mechanism, which includes a support plate, two clamping claw assemblies, a clamping drive assembly, and two connecting rods. The clamping drive assembly can drive the two clamping claw assemblies to approach each other in a preset direction to clamp the goods and move away from each other to release the goods. Although the structure is simple. However, its shortcomings are as follows: it is radially arranged on the rack, which increases the space occupancy rate of the rack. Moreover, it can only clamp the goods to the rack, and manual operation is required to pick up the goods.
