TUBING MATERIAL INNER SURFACE INSPECTION DEVICE AND INSPECTION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive tubing material inner surface inspection device having a simple configuration and capable of performing highly accurate image processing, and inspection method using the tubing material inner surface inspection device.SOLUTION: The tubing material inner surface inspection device includes: a diffusion light source disposed at one opening end of a tubing material; a camera disposed at the other opening end of the tubing material via a focus movable type zoom lens; optical axis adjusting means for matching the optical axis of the camera with a central axis of the tubing material; and light-shielding means for inputting information only on the tubing material inner surface in the camera.SELECTED DRAWING: Figure 1
