[0036] Embodiment 1

[0037] Compared with the common detection mechanism, the key point of the application is to detect a limited number of non-standard parts, and the conventional detection quantity is within 100 pieces / time. The application is mainly aimed at miniature metal bellows, and the classification is realized by analyzing and detecting the mature internal endoscopic detection mechanism.

[0038] In the application, the control system 7 is an existing scheme, and there are many optional schemes. The working principle is that the detection result is obtained, and the signal is output to the blanking cylinder 52 and the holding cylinder 32.
