[0039] The technical solution in the embodiment of the present application has the following overall idea: after the PLC controls the robot to move to the material placement area and positions the lower box, the robotic arm grabs the lower box and moves it to the scanning area of ​​the barcode scanner to scan the barcode on the lower box to obtain the box number. Then the PLC controls the robot to move the lower box to the loading area, and generates and stores the loading log based on the box number, thereby realizing automatic loading of the lower box, thereby improving the loading efficiency and safety of the lower box and reducing the loading cost.

[0051] The PLC controls the robot to move the lower box to the loading area, stack the lower box based on the preset stacking rules, and generate and store the loading log based on the box number and the current time to complete the automatic loading of the lower box. The PLC encrypts the loading log with the preset key and stores it in a distributed manner on the cloud server for backup.
