Metal surface defect online detection device and method based on image processing

Abstract

The invention discloses a metal surface defect online detection device and method based on image processing, belongs to the field of metal defect detection equipment, and solves the problems that the metal surface defect detection efficiency is low, the instrument cost is high, and the detection precision and efficiency of the metal product quality are influenced in the traditional technology. The metal surface defect online detection device comprises a conveyor belt and detection devices connected with a computer, and is characterized in that the detection devices are arranged at the top and the side part of the conveyor belt, a plurality of pieces to be detected are arranged on the conveyor belt, and the detection devices are used for detecting whether surface defects and notches of the pieces to be detected are square or not, so that the detection cost is reduced, the overall structure is simple, and the workpiece defect detection efficiency and speed can be effectively improved.

Description

technical field [0001] The invention belongs to the field of metal defect detection equipment, and in particular relates to an image processing-based online detection device and method for highly reflective metal surface defects. Background technique [0002] A region of localized physical or chemical inhomogeneity on a metal surface. Including non-metallic inclusions and other second-phase particles, dislocations or grain boundary outcrops, adsorbed impurity atoms, surface vacancies or steps, etc. Surface defects are the parts with high atomic activity, which often become the origin of metal corrosion. [0003] Vulcanized rubber products sometimes have defects such as scars, blisters, cracks, spongy, inconsistent color, heavy skin and other defects on the surface. Under-sulfur and over-sulfur are caused by other reasons. In order to avoid these disadvantages, the operation requirements should be strictly controlled and the process conditions should be well controlled. ...
