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 machine vision-based automatic detection device and method for brake disc air duct defects. Background technique

[0002] Automobile brake discs are mainly produced by casting. Due to the casting process, brake discs are prone to defects such as trachoma, air scars, sticky sand, and lack of meat during the casting process. Brake disc air channel defects refer to defects distributed inside the hollow brake disc air channel, and most of the defect types are seams and punctures.

[0003] At present, most brake disc manufacturers still use the traditional manual visual inspection and listening method to judge whether there are defects inside the brake disc air duct. This method has high labor costs, inaccurate detection results, and low detection efficiency. Contents of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the ...
