AUTO OPTICAL INSPECTION SYSTEM

摘要

The present invention discloses an automatic optical inspection device having improved testing power and securing inspection capabilities by emitting different lights to overlapping image frames during an inspection. The automatic optical inspection device according to the present invention comprises: a stage on which an inspection target is mounted; a photographing unit for photographing the inspection target on the stage; a lighting unit for emitting lights to the inspection target; and a moving unit for linearly moving the stage or the photographing unit to change the relative position of the inspection target to the photographing unit. The moving speed of the moving unit is determined to partially overlap an n^th image and an (n+1)^th image photographed in the photographing unit.
