In the traditional production mode, the stamping production of automobile body panels is carried out on the closed production line, and the stamping receiving line cannot be monitored in real time during the production process. Therefore, a monitoring system for the stamping receiving line was built by the visual non-contact detection technology combined with image AI algorithm, and the six high-speed lenses arranged inside the production line were triggered by the signal of production line press to take pictures and automatically perform template matching with the reference image, which could realize the real-time monitoring of receiving line in different areas of drawing parts in the environment of strong vibration and high beat, output the deviation values of receiving lines in eighteen monitoring areas, and give early warning to the parts exceeding the set threshold. Then, the production and maintenance personnel could adjust the pressure values in the corresponding area according to the curve deviation without stopping the machine, and the waste and return rates of parts for production line and the loss of shutdown efficiency were greatly reduced. The result shows that after the system is put into operation, it is expected to save 260000 yuan in annual waste and return parts and 90000 yuan in shutdown efficiency.
