There are some large and medium-sized workpieces in automobile parts and engine parts, the diameter of which is between 50 mm and 200 mm. Due to the low accuracy of manual detection, once the error occurs, it will have a very serious impact on the quality of the car, and even damage the company's corporate image. More and more automobile manufacturers begin to use visual inspection system to control the integrity of auto parts.
With the development of the industrial age, visual inspection equipment has gradually entered everyone's life, and machine vision is also gradually familiar to more people. In fact, machine vision is carried out through screening machines. The industries involved include: hardware and electronics, mobile phone parts, fasteners, automotive fasteners, aviation fasteners, mobile phone precision parts, rubber and plastic products, magnetic materials products, etc.
In the automotive fastener accessories, the screening machine usually involves the aspects that can be detected: dimensional defects, center, leakage, welding, sorting and other visual inspection.
Automobile parts detection system can identify the image features and analyze the image signal to determine whether the product meets the requirements. The detection process is fully automatic. When there is an abnormality in the product detection, it will send out the abnormal signal and send the product to the OK or ng blanking box.
How does the visual inspection system work?
Measure the product size and judge according to the product contour.
Detect defects, such as obvious scratches, scratches and missing on the products. According to the photos, whether the product is defective can be determined. With the application of camera technology, the higher the pixel, the more obvious the judgment of product defects.
Surface contamination detection, if the product surface is contaminated, it can be identified.
Test the integrity of the product, regardless of whether the product has cracks or leakage treatment.
Visual inspection of auto parts is one of the earliest applications in machine vision industry. The production and assembly requirements of automobile parts are very high. Only by using advanced automatic detection technology can we meet the high standard requirements of automobile manufacturing industry, ensure the qualified rate of automobile parts production and guarantee the quality of automobile.
