DEVICE FOR DETECTING AND CLASSIFYING RESIDUAL OXIDE IN METAL SHEET PRODUCTION LINES

摘要

The invention is especially designed for totally automatic detection of residual oxide stains (residual scale) and classification thereof in sheet metal production lines without need to stop the line; the invention consists in a framework or box (4), equipped with means for movement (8) on the surface of the metal sheet (2) to be examined, and containing a high-resolution CCD camera (1), a high-power lighting unit (6-7) and a diffuse light generator; the video signal of the camera is sent to a PC (3) equipped with software for processing the images obtained, so that the residual oxide stains may be detected and classified. The movement of the said box or framework (4) is controlled by a programmable automaton (14), also connected to said PC (3).
