Inspection Method and Inspection System for Pillar-shaped Honeycomb Structure
30 Sep 21
A method for inspecting a pillar-shaped honeycomb structure includes steps of: capturing a pattern of reflected light from an end face with a camera and generating an image data of the pattern of the reflected light; distinguishing positional information of each of cells adjacent to an outer peripheral side wall and cells that are not adjacent to the outer peripheral side wall based on the image data of the pattern of the reflected light, and storing the distinguished positional information in a memory; capturing a pattern of transmitted light from the end face with the camera and generating an image data of the pattern of the transmitted light; measuring intensity of each transmitted light from the cells adjacent to the outer peripheral side wall to detect the cells having defective plugged portions that are adjacent to the outer peripheral side wall based on the generated image data of the pattern of the transmitted light and the positional information; and measuring intensity of each transmitted light from the cells that are not adjacent to the outer peripheral side wall to detect the cells having defective plugged portions that are not adjacent to the outer peripheral side wall based on the generated image data of the pattern of the transmitted light and the positional information.
