A machine vision inspection system for industrial parts such as plastic
molded caps or the like can reliably detect defects at very high
inspection rates on the order of 1600 per minute of a variety of cap
colors and liners including previously difficult to inspect combinations.
Advantageously, the system includes an inclined inspection ramp which
provides separation between the caps which are processed through an
inspection station to provide accurate imaging of each individual cap
without interference from adjacent caps. Further, the inspection station
includes a reflective device which provides accurate and reliable imaging
of numerous views of caps with a single color to detect and identify
defects.
