PROFILING CONTROL DEVICE, WELDING ROBOT SYSTEM, AND PROFILING CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a device desired by a user to execute welding torch profiling control without using any laser sensor, because the welding torch profiling control can be executed by using a laser sensor but the laser sensor is very expensive.SOLUTION: The profiling control device includes an image processing device, and a robot control device. The image processing device derives the shifting amount of a beveling part with respect to a welding torch based on the position coordinates of the reflected image of a welding electrode obtained from a captured image. The robot control device corrects the position coordinates of the welding torch based on the shifting amount to execute welding torch profiling control. Thus, profiling welding can be executed without using any laser sensor.SELECTED DRAWING: Figure 1
