VISION INSPECTION SYSTEM THAT USE DIVIDED ILLUMINATION

摘要

A vision inspection system using divided lighting is provided to detect mounting state of an object by dividing a lighting unit into a plurality of areas and lighting the areas independently. A vision inspection system using divided lighting comprises a main body(10), a lighting unit(20), a camera module(30) and a vision processing unit(40). The vision inspection system inspects a state of a component mounted on a printed circuit board(PCB). The lighting unit is divided into a plurality of areas to discriminate mounting state of the component using shadow phenomenon. The areas of the lighting unit are selectively turned on/off by a lighting control program embedded in the vision processing unit.
