Context
Surface-defect inspection relied on operator judgement at the end of a three-shift line. Defects escaping to assembly were expensive and inconsistently recorded.
Constraints
Works council and IT security ruled out sending line imagery off-site. Cycle time allowed under 100 ms per part, with no room for a workstation at the station.
What we built
A vision model distilled from 60,000 labelled frames, quantised onto a Xelec-designed board at the station, with store-and-forward telemetry and OTA updates across eleven lines.
Outcome
Inference settled at 38 ms median, escaped defects fell sharply against the prior quarter, and no imagery leaves the plant network.
