Problems solved by technology

[0003] At present, the automation of the tortuous and irregular welding of the weld cannot be realized on the coordinate welding robot, and the welding can only be performed by manually observing the weld.
For many and complex welds, manual labor may forget a certain weld

Embodiment Construction

[0043] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0044] attached figure 1 It can be seen that a CAD drawing technology guides the robot automatic welding method,

[0045] On the 3D CAD weld seam drawing, the simulation teaching is carried out through the 3D drawing, and the movement trajectory and posture of the 6-axis robot of the 3D simulation are directly marked;

[0046] Convert the above trajectory and posture into a robot program or a language that the robot can understand through coordinate transformation;

[0047] The robot receives control instructions, uses the vision system camera to identify the feature points of the workpiece, and guides the robot to complete welding.

[0048] Generate 3D CAD drawings of processed products and import 3D CAD drawings into the control system;

[0049] The control system performs simulation drive; generates a six-axis robot walking welding trajectory;

[0050] Disp...

Abstract

The invention relates to a method for guiding a robot to conduct automatic welding through the CAD drawing technology. The method comprises the steps of conducting simulating demonstration on a 3D CADwelding joint drawing through a 3D diagram and directly marking 3D simulation six-axis robot moving tracks and postures; converting the above tracks and postures into a robot program or a language which the robot can read through coordinate transformation; recognizing feature points of a workpiece through a visual camera after the robot receives a control command and guiding the robot to completewelding. Through the method for guiding the robot to conduct automatic welding through the CAD drawing technology, the stability and the welding quality are improved, and the welding uniformly is ensured; the labor conditions are improved; the labor productivity is improved; the product model changing and updating cycle is shortened, and the corresponding equipment investment is reduced.

Description

technical field [0001] The invention relates to a welding method, in particular to a robot automatic welding method guided by CAD drawing technology. Background technique [0002] Usually, the robot welding will go through the whole process by teaching in advance, and observe with the naked eye whether the trajectory of the robot welding torch is consistent with the welding seam line, which is actually equivalent to one more welding. With or without a computer, you can give the robot a quick drill in 3D simulation through the weld parameters. [0003] At present, the automation of the tortuous and irregular welding of the weld cannot be realized on the coordinate welding robot, and the welding can only be performed by manually observing the weld. For many and complicated weld seams, a certain weld seam may be forgotten manually. Contents of the invention [0004] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a CAD drawing tec...
