Project Details
Problem Statement: The customer required an automated machine that could inspect plastic injection molded parts for critical dimensions and physical defects prior to assembly. The required cycle rate was two seconds per part. Rejects were quarantined into a locked bin with verification. Vision inspection was performed using two Keyence LJV-7200 lasers mounted to capture the entire top and bottom of the part.
Vision performance criteria included the following:
- Broken terminal walls
- Chipped surfaces
- Broken or missing plastic protrusion
- Feature height
- Blocked holes from flashing
