Cap defect detection

The inspection point

A faulty cap is the most common cause of leakage after filling and of the complaint that follows. The defects are small, varied, and you rarely have a photograph of each one in advance: a hairline crack in the hinge, a locking lug that never engaged, a chip on the rim. Line speed rules out human inspection, so the decision has to be made in milliseconds.

How it runs on the line

The unit is mounted over the conveyor where the caps pass in a single lane. Anomaly and defect detection trains on good caps only and flags anything that deviates from the appearance it learned, which is what catches failure modes nobody photographed first. The decision goes to the PLC as pass/fail for every part, and the reject signal drives the ejection actuator.
