Linear array CCD-based ABS gear ring defect online detection device and method

Abstract

The invention discloses a linear array CCD-based ABS gear ring defect online detection device and method. A linear array CCD camera is used for performing linear scanning on an ABS gear ring to be detected, and based on the splitting of an image processing technology of the linear array CCD, the gray level image recurrence and defect detecting processing are realized. A complete gray level image can be acquired by only one circle of rotation of the ABS gear ring, thus realizing defect complete scanning detection. The linear array CCD camera has the characteristics of high flexibility, large dynamic range and high frequency response, and the linear array CCD camera is used for performing defect detection of the ABS gear ring, and can realize the detection more accurately and faster compared with the prior art. The linear array CCD image processing technology-based ABS gear ring online defect detection device is suitable for ABS gear rings of different types and more accords with actual needs.

Description

technical field [0001] The invention relates to a defect detection method of an ABS ring gear, in particular to an on-line defect detection device and method for an ABS ring gear based on a linear array CCD image processing technology. Background technique [0002] With the wide application of automobiles in our daily life, people pay more and more attention to the safety performance of automobiles, and the reliability of automobile ABS system has become the content that people pay more and more attention to. The reliability of automobile ABS system directly affects the life and property safety of automobile users and social public order. In the ABS system, the ABS ring gear is the key to the input signal of the system, so the detection of the defect of the ABS ring gear is particularly important. [0003] The ABS ring gear is mostly made of ferromagnetic materials, such as No. 35 steel and No. 45 steel, and its surface is mostly galvanized or chrome-plated. The production...

Problems solved by technology

At present, the detection methods commonly used in the industry, such as mechanical method, projection method, tooth induction detection method, etc., are mostly used to detect the pitch error of the ring gear. The above detection methods can detect defects such as missing teeth, scratches, indentations, etc., but cannot detect Rust spots, effusion and other defect types cannot effectively detect ABS ring gear defects

In addition to the above detection methods, there is also a method on the market that simulates the working environment of the automotive ABS system for ABS ring gear detection, which can effectively detect ABS ring gear defects, but the cost of testing equipment is high and the loss is large, and it can be judged whether the ABS ring gear is defective. , but the defect type cannot be determined
