In order to solve the problem of poor manual inspection and assembly accuracy of traditional pump body mouth ring,a pump body mouth ring assembly system platform based on machine vision was constructed.The key issues such as light source lighting,industrial camera and lens selection,and image acquisition during the assembly process of the pump body mouth ring based on machine vision were studied.The visual detection algorithm of the pose and dimension parameters of the pump body mouth ring was designed,and the hardware and software of the pump body mouth ring assembly system platform and the assembly process were discussed.The experimental results show that the proposed visual detection algorithm for the assembly process of the pump body mouth ring can accurately identify and detect the pump body mouth ring in the image,and has practical significance for improving the accuracy and flexibility of the pump body mouth ring assembly process.
