Rolling surface defect detection system and method

Abstract

The invention relates to the field of rolling surface defect detection, in particular to a rolling surface defect detection system and method. The rolling surface defect detection system comprises a control device, a light source generation device, a galvanometer and an identification device, wherein the galvanometer is arranged on a light path between the light source generation device and a rolling surface to be detected; the light source generating device, the galvanometer and the recognition device are all in communication connection with the control device; light beams emitted by the light source generating device are projected to the rolling surface to be measured through scanning of the galvanometer to form stripes; the control device adjusts driving signals of the galvanometer to adjust the positions of the stripes projected to the rolling surface to be measured; and the identification device shoots the rolling surface to be detected to obtain multiple target images and detectsthe defects of the rolling surface to be detected according to the multiple target images. The detection accuracy rate of the defects of the rolling surface to be detected can be effectively improvedby detecting and processing the target images shot multiple times, meanwhile, the system is high in detection precision, the detection process is simple and easy to operate, and high market value isrealized.

Description

【Technical field】 [0001] The invention relates to the field of rolling surface defect detection, in particular to a rolling surface defect detection system and method. 【Background technique】 [0002] Parts with rolling surfaces are one of the most commonly used key parts in the equipment manufacturing industry, such as bearings, whose quality directly determines the performance and quality of the product, so it is particularly important to perform quality inspections on the roller surfaces in the bearings . [0003] At present, the commonly used detection method is to irradiate the surface of the roller to be tested with a direct light source, then take a picture of the surface of the roller to be tested with a camera, and send the image of the surface of the roller to be tested to the host computer, and the host computer analyzes the brightness of the surface image The change curve detects the defects on the surface of the roller to be tested, but the above-mentioned detec...
