Glass breakage and scratch
Glass process quality inspection
D Company glass breakage and scratch detection
Short sound signals capture cracks and scratches in glass cutting and transfer processes to reduce defect spread
Target sound
Glass breakage and scratch
Project overview
A case proving that sound can detect breakage and scratches even in glass processes beyond motors and connectors
Field challenge
- Scratch signals were extremely short and small, making them easy to miss with existing methods
- Late defect discovery could increase downstream process loss
- The project could expand horizontally to multiple production tables after validation
Outcome summary
99%+Glass breakage detection accuracy
98.6%+Glass scratch detection accuracy
