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
