Embodiment Construction

[0019] Below in conjunction with accompanying drawing, use novel technical scheme to be described in further detail.

[0020] First, place the workpiece to be welded on the fixture, move three non-collinear points on the original shooting plane through the 6 laser ranging sensors installed on the end of the 3 robot arm, and measure three points to the welding plane The acquired current signal is converted into a digital signal through the 2AD module and transmitted to the 1 industrial control computer; the computer software part analyzes the parallelism of the upper and lower planes according to the obtained information, and transmits the data that needs to be corrected on the camera plane to the 4 robot control cabinet , Adjust the end of the robot arm through the control cabinet so that the shooting plane of the 7 industrial camera is parallel to the welding plane. The plane of the workpiece is photographed by 7 industrial cameras, and the images are sent to 1 industrial con...

Abstract

The invention discloses a visual system of a welding robot capable of automatically correcting position deviation of a welding gun. Before the first work piece is welded, a welding plane and a visual plane are subjected to parallel measurement by a laser ranging sensor, thus the position of the visual plane is adjusted to be parallel with the welding plane. Then, the placing position of the work piece is obtained by an industrial camera and precise demonstration operation is performed on the first work piece. Subsequent work pieces are welded in an identical way and the position of the welding gun is adjusted based on the deviation information obtained through images taken by the industrial camera. Therefore, a problem that an original demonstration program cannot work due to position deviation of the work pieces is solved, repeated demonstration operation is avoided, and working efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of welding robots, which automatically adjusts the position of a welding torch through visual deviation correction technology. Background technique [0002] Existing welding robots generally do not have the function of adjusting the original welding program according to the position deviation of the weldment. The welding path program cannot be used, seriously affecting work efficiency. [0003] When the position of the workpiece changes, the traditional welding robot does not have the function of automatically correcting the welding position. When the position of the workpiece is found to be changed, it is generally adjusted in two ways. The first method is to obtain the correct teaching point of the robot through re-teaching , the second method is to manually adjust the position of the weldment. The above two methods of adjusting the welding position deviation by manpower have great disadvantages, which not only wa...
