Problems solved by technology

However, when the robot is welding, for the welding of a complex workpiece, there is more than one weld seam on the workpiece. Using the traditional offline programming method requires manual clicking on each weld seam, which is time-consuming and laborious.

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments.

[0023] A welding robot welding process control method of the present invention comprises the following steps:

[0024] Step 1. Use SolidWorks 3D software to open the 3D model of the workpiece to be welded and add the weld seam to be welded on the 3D model of the workpiece. Create a new assembly model in the SolidWorks 3D software and import the 3D model of the welding robot and the workpiece to be welded into the assembly model, and adjust the position of the robot relative to the workpiece in the assembly model according to the actual usage.

[0025] Step 2. Use C# programming language to carry out secondary development of SolidWorks. The specific process is as follows:

[0026] Traverse all the welds on the workpiece in the assembly model to get the weld curve of the weld. Read the data of all welds on the workpiece. The data of each weld includes the coordinates of t...

Abstract

The invention discloses a welding process control method for a welding robot. The method is characterized in that through a SolidWorks three-dimensional software secondary-development technology, allwelding seams required to be welded on a workpiece are traversed; a position and posture of a tail end are determined according to traversed weld seam data when the robot welds each point on the weldseams, then robot inverse solution operation is performed to obtain corner data of each joint when the robot welds each point on the weld seams, and a welding program for controlling the robot to workis generated by taking the corner data of the joints as parameters of a robot control instruction. When the method is used for off-line programming of the welding robot, the robot welds the workpiecewith the plurality of weld seams, all welding procedures are automatically generated, the weld seams do not need to be operated one by one, and high efficiency and convenience are achieved.

Description

technical field [0001] The invention relates to a welding robot off-line programming method, in particular to a welding robot welding process control method. Background technique [0002] The method of off-line programming of the welding robot is to make the preparation of the robot welding program, the acquisition of the coordinate position of the welding seam trajectory, and the debugging of the program all be completed independently on a computer without the participation of the robot itself. Off-line programming software is mainly in the form of text. Programmers need to be familiar with all the command systems and syntax of the robot, and also know how to determine the spatial position coordinates of the weld trajectory. Therefore, programming is not easy and time-saving. With the development of computer three-dimensional graphics technology, most of today's robot off-line programming systems can run in a three-dimensional graphics environment, and the coordinate positi...
