Aiming at the neutral problem of manual electromagnetic riveting, a three-coordinate electromagnetic riveting bracket system based on industrial intelligent camera is designed. The riveting holes are photographed by using industrial intelligent camera, and the center coordinates of the holes are rapidly calculated by image processing, finally the result is converted into the assembly coordinate system according to the coordinate transformation. In this paper, the composition, working principle, hardware and software design of the threecoordinate riveting bracket system are described in detail. Siemens Smart PLC motion control function can achieve three coordinate positioning control, and human-computer interaction interface is established by WinCC touch screen. With the actual implementation process, experimental results verify the effectiveness of the positioning function and alignment accuracy of the system.
