[0023] In order to facilitate the lifting seat 44 to accurately lift the jig, the material blocking mechanism 3 includes a material blocking cylinder 30 vertically arranged on the frame 1, a material blocking seat 31 arranged on the cylinder rod of the material blocking cylinder 30, a swing arm 32 hingedly arranged on the material blocking seat 31, and a roller 33 arranged on the swing arm 32 toward the upstream of the conveying component 4. The roller 33 can reduce the wear of the swing arm 32 and the jig. The material blocking cylinder 30 moves quickly and has high execution efficiency. One end of the swing arm 32 toward the upstream of the conveying component 4 is higher than the other end.

[0024] In order to reduce the impact on the swing arm 32 when it is blocking the fixture, an elastic member 36 is provided on the material blocking seat 31, and the elastic member 36 resists the end of the swing arm 32 where the roller 33 is not provided. A vertical positioning column 34 is provided on the material blocking cylinder 30 to support the material blocking seat 31 and further reduce the damage to the material blocking cylinder 30 caused by the impact. The material blocking seat 31 is provided with an avoidance opening 35 for avoiding the positioning column 34, and the positioning column 34 is arranged upstream of the conveyor belt assembly 42.

[0025] In order to facilitate the support of the jig by the lifting seat 44, the conveyor belt assembly 42 includes a first conveyor belt body 420 and a second conveyor belt body 423 arranged on the conveying frame 41 in front and behind, a first pulley group 421 arranged on the conveying frame 41, and a second pulley group 424 arranged on the conveying frame.

The barcode scanner 2 is used to scan the products on the fixture entering the lifting area of ​​the lifting seat 44.

[0029] During random inspection, the jig carries the product and moves downstream along the conveying assembly 4. The barcode scanner 2 scans the products on the passing jig in turn. When the product needs to be inspected, the jig moves to the top of the lifting seat 44. The material blocking mechanism 3 at the rear blocks the jig from moving further downstream. The lifting seat 44 rises to the upper limit under the lifting of the lifting cylinder 435. The sampling personnel or the manipulator takes the product out of the jig for random inspection. After the random inspection is completed, the product is placed in the jig. The lifting seat 44 descends to the bottom of the second conveyor belt body 423, and the jig returns to the conveying assembly 4. This reciprocating process is used to implement random inspection of the products that need to be inspected.
