The first label stores information such as the type, model, and whether it is an urgent item of the electrical product 20. Use the first scanning device to scan the first label and the second label on the tray 23 or the turnover box 15 to bind the electrical product 20, the packing box, and the tray 23 or the turnover box 15. When there is an urgent item, the operator enters the urgent item data when generating the first label, and the urgent item must be placed in the turnover box 15.

[0068] The tray 23 or the turnover box 15 containing the electrical product 20 to be inspected is placed on the first conveying component 16 for conveyance. The AGV cart is connected at the conveying end of the first conveying component 16. The fourth scanning device on the AGV cart scans the second label on the tray 23 or the turnover box 15. The control unit determines whether it is an urgent item. If it is an urgent item, the control unit determines the inspection line corresponding to the electrical product 20 according to the electrical product 20 information corresponding to the second label and sends an instruction to the AGV cart. The AGV cart conveys the turnover box 15 containing the electrical product 20 to be inspected to the urgent item area of the semi-automatic inspection line 4 or the manual inspection line 5 according to the instruction; if it is not an urgent item, the control unit sends an instruction to transport to the to-be-inspected buffer library 9 to the AGV cart, and the AGV cart conveys the tray 23 or the turnover box 15 containing the electrical product 20 to be inspected to the to-be-inspected buffer library 9.
