Testing requirements:
(1) Check if the rubber plug is intact
(2) Check if the two small holes inside the rubber plug are formed and both are through holes
(3) Inspect the surface of the rubber plug for defects such as incompleteness, dents, missing corners, scratches, cracks, etc.

Summary: Based on the use of artificial intelligence deep learning algorithms combined with traditional visual algorithms to ensure detection effectiveness, our visual inspection system can locate rubber plugs and detect various defects, avoiding the problem of misjudgment that traditional algorithms are prone to, and can achieve the required rhythm.
