An online detection system and detection method for round steel surface defects

Abstract

An on-line detection system and detection method for round steel surface defects, belonging to the technical field of metal surface detection, in which two fixed boxes are arranged symmetrically on both sides of the round steel roller table The lower part of the frame is surrounded by a detection channel for the round steel to pass through. A fixed bracket is installed in the fixed box. Multiple industrial camera components are arranged at equal intervals on the two fixed brackets. The imaging ranges of two adjacent industrial camera components overlap or touch each other. , both sides of the detection channel are symmetrically installed with arc-shaped light source components along its circumference. The beneficial effect of the present invention is that the present invention realizes online real-time comprehensive and clear collection of images of the round steel surface, avoiding the situation of shaking in image collection. It effectively avoids the problem of image signal-to-noise ratio reduction, can accurately identify and judge the defects on the surface of the round steel, prevents the problem that the temperature of the round steel is too high and affects the normal collection work, and realizes the automatic online detection of the surface defects of the round steel.

Description

technical field [0001] The invention relates to the technical field of metal surface detection, in particular to an online detection system and detection method for round steel surface defects. Background technique [0002] With the continuous improvement of customers' requirements for the accuracy of round steel, the requirements for the inspection standard of round steel surface quality have also been continuously improved. The surface detection methods of round steel include optical imaging detection method, magnetic flux leakage detection method, infrared detection method, and ultrasonic flaw detection technology, etc. Among them, the most efficient mainstream is optical imaging detection. Its principle is to shine light on the surface of round steel In the above, a high-speed CCD camera is used to obtain the surface image of the round steel to detect the defect information on the surface of the round steel. [0003] In the production process, round steel often has defe...
