Under the action of the adsorption component 3, the lid is adsorbed on the surface of the conveyor belt 102 in the first conveying mechanism 1, and then transported to the first detection component 4 for detection of the integrity of the lid lower surface. If the lid is detected to be unqualified, the first rejection component 5 will reject the unqualified lid, and the qualified lid will continue to be transported to the second conveying mechanism 2 through the first conveying mechanism 1, and then the lid will come to the second detection component 6 on the second conveying mechanism 2 for detection of the integrity of the lid upper surface. If the lid is detected to be unqualified, the second rejection component 7 will reject the unqualified lid, and the qualified lid will continue to be transported to the next processing step through the second conveying mechanism 2. The present invention can conveniently perform complete detection of the upper and lower surfaces of the lid without causing damage to the surface of the lid, and can improve work efficiency.

Among them, the negative pressure cavity 301 is a cavity structure, and two mirror-symmetrically arranged pipeline ports are arranged on it, and the pipeline ports are connected to the negative pressure pump 302 through a delivery pipe. Since the negative pressure cavity 301 has the adsorption port 10 and the conveyor belt 102 is distributed with through holes 9, the negative pressure pump 302 works, and under the action of negative pressure, the lid is adsorbed on the surface of the conveyor belt 102.
