in the detection, the plug 22 and the push plate 24 are mainly used for plug and pull detection. As shown in fig. 12, a common seat belt lock S is shown, which has a jack 100 and a push switch 200, and after the seat belt lock S is positioned by the clamp 3, a plug 22 is driven by a first detection cylinder 21 to be inserted into the jack 100 of the seat belt lock S, and a detection sensor for determining that the plug 22 is inserted into place is provided in the seat belt lock S, so that electrical detection of the seat belt lock S can be achieved. After the electric detection is finished, the plug 22 is required to be pulled out, at the moment, the second detection cylinder 23 drives the push plate 24 to push the push switch 200 of the safety belt lock head S, the locking of the safety belt lock head S to the plug 22 is released, the first detection cylinder 21 can drive the plug 22 to reset, and then the second detection cylinder 23 drives the push plate 24 to reset, so that the plugging detection of the safety belt lock head S is completed;

in order to facilitate the assembly and disassembly of the seat belt lock S on the clamp 3, the clamp 3 has a structure, as shown in fig. 5, in which the clamp 3 includes a base 31, a profile seat 32, a connection block 33, a pressing plate 34, a pin 35, and a spring 36.

Under the condition that the upper shell and the lower shell of the safety belt lock head S are not firmly connected, the upper shell and the lower shell can be broken away, so that the safety belt lock head S can be judged to be unqualified. The detection process is performed before the electrical detection and the plug detection, and when the shell of the safety belt lock head S is unqualified, the detection is stopped, and the electrical detection and the plug detection are not performed any more, so that the detection efficiency and the production cost are prevented from being influenced due to scrapping caused by the quality problem of the shell after the electrical detection and the plug detection are qualified.

Wherein, as shown in fig. 1, the visual inspection mechanism 9 is disposed on the frame 1, and the visual inspection mechanism 9 faces the press inspection mechanism 4. With the above structure, the visual detection mechanism 9 is used for assisting the press detection operation of the press detection mechanism 4, and after the press detection by the press detection mechanism 4, the safety belt lock S is detected by the visual detection mechanism 9 to judge that the safety belt lock S is qualified.
