VISION SYSTEM FOR INDUSTRIAL PARTS

摘要

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 light source which is provided on the back side of the cap in the form of an infrared LED strobe light which provides accurate and reliable lighting for appropriate imaging of caps of any color to detect and identify defects therein.
