Paper Abstract

The industry welding robot can't real-time adjust its movement path according to the change in the position of the workpiece in a welding procedure, which affects the quality of welding a lot. The Real-time Visual Measuring and Tracking system acquires the three coordinates of the workpiece by visual measurement method, and navigates the robot to the correct position, consequently the welding quality improves. The system mainly includes micro structured-light visual sensors, a high-speed data processing unit, a display and setting unit, and protection equipments. From the experiment, it's shown that the system can measure the workpiece six times per second, and the precision of the measurement is better than 0.3mm. In a word, the system can effectively improve the robot welding quality.
