Vision systems (also called Optical Inspection systems) use cameras and controls to orient parts that could not otherwise be oriented using conventional techniques in vibratory feeder bowls and centrifugal feeders. Vision systems analyze each part that passes the camera and based on the desired orientation, the part can be allowed to pass or the controls can actuate an air jet or mechanical cam to either properly orient the part, or send it back into the feeder for recirculation.
Applications where vision systems are useful include:
- Parts that must be oriented or sorted based on internal features.
- Parts with different colors.
- Sorting for quality issues such as missing or malformed threads.
- High-speed sorting.
