APPARATUS FOR INSPECTING VISION USING MULTIPLE LATTICE PATTERNS HAVING DIFFERENT COLORS

摘要

An apparatus for inspecting vision using multiple lattice patterns having difference colors, according to the present invention, is for photographing with a camera an inspection object, which is assembled or mounted in a parts assembly process, and then comparing the photographed image with an object image that is inputted in advance to determine whether the inspection object is satisfactory or defective, and comprises: a stage portion for fixing or transferring the inspection object to an inspection position; a lighting portion, which is positioned on the upper portion of the stage portion, for providing light on the inspection object; a central camera portion, which is positioned at the center of the lighting portion, for obtaining a two-dimensional shape of the inspection object; side camera portions which are arranged in a plurality on the side portion of the central camera portion; a plurality of lattice pattern irradiation portions, which are arranged on the side portion of the central camera portion, between the cameras in the side camera portion; a vision processing portion for reading the image that is photographed by the central camera portion to determine whether the inspection object is satisfactory or defective; and a control portion for controlling the stage portion, the lattice pattern irradiation portion, and the camera portion, wherein one lattice pattern irradiation portion from the plurality of lattice pattern irradiation portions irradiates a lattice pattern having one predetermined color and a large period, and the other lattice pattern irradiation portion irradiates a lattice pattern having another predetermined color and a small period.
