Finally, the suction nozzle can firmly adsorb the screen so that the screen is stably positioned. When the next screen positioning detection is performed, the suction pump can be stopped to make the internal air pressure of the cavity normal, and the screen can be taken out to replace the next one.

The two cylinders can control the lifting and lowering of the sliding frame inside the operating table, so that after the two support plates are set up on the screen, the sliding frame is lifted up by the cylinders, and the negative pressure of the suction nozzle adsorbs the screen, and finally the inspection is carried out.

[0012] As a further solution of the utility model, a positioning plate is fixedly connected to the top of the operating table, and a second rubber pad is fixedly connected to the top of the positioning plate. The second rubber pad can increase friction and prevent slipping, and the positioning plate can facilitate horizontal alignment of the screen.

[0013] In summary, the present invention includes at least the following beneficial technical effects:
