Inspection method and inspection system for pillar-shaped honeycomb structure made of ceramic

An inspection system for carrying out an inspection method for a pillar-shaped honeycomb structure, the inspection system comprising:

• a robot arm with a robot hand at a tip of the robot arm, the robot hand comprising a pair of flat gripping surfaces directly opposed from each other capable of gripping the pillar-shaped honeycomb structure from a first end surface and a second end surface, the pair of flat gripping surfaces being configured to be able to rotate the pillar-shaped honeycomb structure around a rotation axis perpendicular to the pair of flat gripping surfaces at a predetermined rotational speed while gripping the pillar-shaped honeycomb structure from the first end surface and the second end surface;
• an area camera for a side surface;
• a screen that can display strip-shaped images;
• and
• a controller that can at least set a rotation speed of the pair of flat gripping surfaces and a shutter speed of the area camera for the side surface.
