Abstract：

With the development and application of industrial robot and machine vision technologies, the robot automatic feeding system guided by machine vision suitable for forging conditions was developed by combining the two technologies, which was composed of industrial robot, electromagnet mechanism, visual camera, control system and lighting system. Through the processes of working condition setting, photographing, data processing and positioning, the robot automatically grabbed the cold-state bar from material box and transported it to the heating unit of forging line. Then, how to deal with the problem of photo identification caused by the influence of light, the calibration and conversion of coordinate system for robot and vision system, the visual processing process, the positioning and fault tolerance processing of clamping system, and the analysis and processing of empty grip problem, etc. were described in detail. Furthermore, the system continuously adjusted and optimized during the half-year application process, and the success rate of reclaiming was more than 99%. The application results show that the system has reliable stability and safety.
