Abstract

The invention discloses a brake disc air duct defect automatic detection device and method based on machine vision, and relates to the field of image recognition. The device comprises at least one light source assembly, at least one image collection assembly, a rotation driving assembly, and a defect automatic detection assembly. The light source assembly is used in cooperation with the image collection assembly and used for collecting images in a brake disc air duct; the rotation driving assembly is used for driving the brake disc to rotate or driving the image collection assembly to rotate around the brake disc; and the defect automatic detection assembly judges whether the air duct of each brake disc has defects or not. According to the device, clear images in the brake disc air duct are collected through the image collection assembly, whether defects exist in the brake disc air duct or not is judged through a defect detection algorithm model trained by a control mechanism, the detection efficiency of the brake disc air duct is improved, meanwhile, the accuracy of the detection result of the brake disc air duct is improved, and the labor cost of brake disc air duct detection isreduced.

Description

Technical field [0001] The invention relates to the technical field of image recognition, in particular to a device and method for automatically detecting defects in the air duct of a brake disc based on machine vision. Background technique [0002] Automobile brake discs are mainly produced by casting. Due to the casting process, the brake discs are prone to defects such as blisters, gas scars, sticky sand, and lack of meat during the casting process. Brake disc air duct defects refer to defects distributed inside the hollow brake disc air duct, and most of the defects are stitched and punctured. [0003] At present, most brake disc manufacturers still use traditional artificial visual observation and listening methods to judge whether there are defects in the brake disc duct. This method has high labor costs, inaccurate detection results, and low detection efficiency. Summary of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the pr...
