[0018] Step 1, place the mobile phone cover on the limit bracket in the placement base, then the small air pump works to inject gas into the limit airbag through the air pipe to squeeze and limit the edge of the mobile phone cover, and then the cylinder extends to push the upper module down. As the upper module descends, the card rack is stuck in the card slot, and the high-temperature resistant sealing pad layer is pressed down on the mobile phone cover. The exposed area of ​​the mobile phone cover is divided into four by the detection chamber, wherein the size of the detection rack is not specified in this application, and four mobile phone covers of equal size can also be placed in the same lower module, and different types of detection can be performed on the four covers at the same time;

The fill light 64 provides light to facilitate shooting the surface of the mobile phone cover;

[0049] Step 4. As the conveyor belt 4 moves, the mobile phone cover is inspected during the movement, and each inspection unit transmits the inspection data to the background. After the inspection is completed, the mobile phone cover may be damaged and has no use value.
