Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039]It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0040] see figure 1 and figure 2 The first embodiment of the present invention provides a rolling surfac...

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...
