[0051] Detection principle: For normal AF cover products, since AF is on the glass surface, the sprayed water vapor is attached to the AF surface. Due to the hydrophobic nature of AF, the water vapor will condense into many small water droplets, and a layer of misty water vapor will be seen on the surface of the cover. If the AF is partially or completely missing from the glass surface, the water vapor will directly attach to the glass surface, and the glass has a strong hydrophilic property, so the water vapor will be dispersed and spread out on the glass surface, and there will be no misty appearance.

[0052] A person can stand on one side of the cabinet 4 close to the first cylinder 212 to manually pick up and place the product, and place the glass cover plate to be tested in the inclined carrier box 210. At this time, one end of the cover plate extends out of the carrier box 210 to facilitate taking and placing. After the placement is completed, the first cylinder 212 drives the guide wheel 213 to descend. At this time, the carrier box 210 rotates to a horizontal level, and the turntable 205 rotates to make the carrier box 210 with the cover plate rotate to the bottom of the protective cover 303. The second cylinder 302 pushes the protective cover 303 to descend and cover the cover plate. The steam generator and the steam spray The steam nozzle 213 is connected to the cover plate 214 and water vapor is sprayed onto the cover plate through the steam nozzle 214 to realize a comprehensive inspection of the AF film on the cover plate surface. Then the protective cover 303 rises driven by the second cylinder 302, and the turntable 205 rotates so that the cover plate sprayed with water vapor moves to the bottom of the visual inspection camera 504 and is inspected by the visual inspection camera 504. The inspected product arrives under the guide wheel 213, and the first cylinder 212 pushes the guide wheel 213 to rise and lift the corresponding carrier box 210, and then the inspected cover plate is removed and the cover plate to be inspected is placed.
