The embodiment of the invention discloses a method for calibrating the path of a welding robot. The method includes installing an image acquisition device at a predetermined position of the welding robot, the image acquisition device transmits and displays the shape image of the collected workpiece to the display screen, and is used to obtain the real-time trajectory of the welding point. The real-time trajectory and the shape image of the workpiece are used to calculate and acquire calibration values of each welding point, and to calibrate the welding path of the welding robot based on the calibration values. The method provided by the embodiment of the present invention visually compares the reference path and the real-time welding trajectory through the display screen, thereby effectively improving the efficiency and accuracy of path calibration, and avoiding the hidden dangers of the existing calibration methods. The present invention also provides a device for calibrating the path of a welding robot corresponding to the above method.
Description
technical field [0001] The present invention relates to the technical field of welding robots, in particular to a display-based method for calibrating the path of a welding robot, and a display-based device for calibrating the path of a welding robot. Background technique [0002] At present, before the welding robot is officially put into production and operation, the welding path of the welding robot is programmed by the software engineer in the controller of the welding robot according to the required workpiece shape. Therefore, if a welding robot does not change the software planning path, it can only complete the welding task of one type of workpiece, thus causing the limitation of on-site welding operations. Furthermore, the welding path calibration of the existing welding robot is performed by the operator through the teaching box and the jog operation of the welding head with eyes. This calibration method is not only time-consuming and laborious, but also has low cal...
