Abstract

The arc welding robot control platform with automatic visual weld seam tracing function includes a controller to control the robot, a robot to weld with the movable welding torch, a computer to calculate the parameters of the robot and control the robot via the controller, a laser to send planar laser beam to the welded workpiece, a CCD camera fixed to end of the robot to obtain the image formed by the planar laser beam to light the welded workpiece and to feed the picked image via video wire to the computer for processing. The present invention has opened structure system and can control various industrial robots, servo controller and video device for different functions.

Description

technical field [0001] The invention relates to a general industrial robot control system, in particular to an arc welding robot control platform with the function of visual welding seam automatic tracking. Background technique [0002] The basic structure of the traditional industrial arc welding robot system is as follows: figure 1 As shown, A1 is the controller, R1 is the industrial robot, H1 is the welding torch, and G1 is the workpiece to be welded. The main working method of this system is teaching and reproduction, that is, before welding, the end welding torch of the robot is manually controlled to move along the weld seam, and the position of each motor track point is recorded during the movement, so as to calculate the weld seam position and Complete welding tasks. One of the disadvantages of this method of operation is that the teaching work is cumbersome and takes up more man-hours. This defect is particularly prominent when the weld seam is relatively irregula...
