Description

Technical Field

[0002] The automobile industry has developed into one of my country's pillar industries. In the process of automobile manufacturing, most metal parts are obtained by stamping processing and forming. Stamping technology is an important process method for automobile production. Stamping processing has the characteristics of high production efficiency, low cost, and high material utilization rate. Various types of covering parts on the car body, a large number of automobile parts such as supporting parts inside the car are manufactured by stamping technology, and stamping parts account for a large proportion of automobile parts. Therefore, the level and ability of stamping processing methods largely determine the cost and quality of automobile manufacturing in my country, and also affect the technological progress of other industries involving stamping processing production. In the stamping process, due to mold matching and vibration and other reasons, surface wrinkling, surface distortion, local depression and convexity often occur, resulting in large shape errors on the surface of automobile stamping parts, and even becoming scrap. The existence of various stamping defects will have different degrees of impact on the use of stamping parts. For example, the surface quality of the outer covering parts of the automobile body directly affects the local visual effect after painting, and ultimately affects the appearance and sales of the product; The original machine vision system used closed-circuit television imaging to achieve image acquisition of the workpiece to be inspected, and the only way to obtain the image was the video signal. Although this method has many disadvantages, the transmission of video signals through electronic circuits can basically complete the inspection. The research on machine vision inspection technology developed earlier abroad. The first to appear was the hand-eye system in industrial inspection; then, the automobile manufacturing industry began to use machine vision inspection; in the 1990s, benefiting from the rapid development of integrated circuit technology and other technologies4, visual inspection technology has made great progress.
