With the improvement of automotive fabrication technology and the trend of modularization, today’s cars have more complex procedures, more diverse appearances, and more powerful performance. The specification requirements for auto parts in the automobile manufacturing industry are becoming more and more accurate. The quality of auto parts directly affects the stability and safety of the car, so the testing requirements for auto parts are also getting higher and higher.
The traditional auto parts inspection method adopts manual method, but due to the very complex structure of auto parts, there are usually dozens of inspection points on a product, which takes a lot of time, and this inspection mode is automated. Low level, low measurement efficiency, low sampling frequency, low precision, lack of data support for product quality and other issues. At the same time, this kind of measurement is not suitable for modern management, and can no longer meet the requirements of high-efficiency and high-speed production. Therefore, the inspection of auto parts gradually uses machine vision instead of manual inspection to improve work efficiency, accuracy, and reduce labor costs.
Applying the machine vision system to the inner diameter measurement, outer diameter measurement, appearance defect detection, etc. of auto parts molding products, the high precision, high stability and high versatility brought by the perfect cooperation of industrial cameras and industrial lenses greatly Improve work efficiency, help users shorten product testing time, and improve the accuracy of testing results.
An optical automatic inspection machine for auto parts is composed of automatic feeding and conveying mechanism, machine vision inspection system, and automatic sorting mechanism. It uses industrial cameras to collect image signals of auto parts, and optimizes the design of optical imaging and lighting systems to improve image quality. quality, and improve edge detection accuracy through image prefabrication. Realize precise dimensional measurement of auto parts and identification and classification of defects such as collapse, dislocation, end face damage, cracks, etc., so as to effectively control product quality and conduct more accurate statistical analysis of quality management data.
This optical automatic inspection machine has a high detection speed, which is equivalent to 2-4 skilled workers working at the same time. The equipment can not only automatically feed materials, but also quickly complete the turning of the workpiece and realize the rapid detection of the front and back of the workpiece; it can also be used in different models. The fast switching between workpiece inspections meets the detection and measurement of various types and sizes of auto parts, which is of great significance to the assembly, management, maintenance, tracking of parts and the quality assurance of automobile manufacturing.
