[0030] The product storage and retrieval mechanism is cleverly designed with a high degree of automation. When the pallet loaded with products moves to the waiting position to prepare for feeding, the first transport module drives the pallet from the waiting position to the picking position, and then uses the camera module to take photos of all the products on the pallet for identification, and sends the product location information to the control host, so that the background can understand the specific information of all the products on the pallet, and then according to the user's input of the target product storage or retrieval instructions in the background, the control host controls the second transport module and the Z-axis moving module to cooperate with each other to drive the picking component to move above the target product to pick up the material, and then put the target product into the drop port to complete the storage or retrieval, which not only has high precision and accuracy in retrieval, but also improves work efficiency.
