Abstract

The present invention is applicable to the field of welding robots, and provides a method for optimizing a welding path of a robot. The method includes: obtaining an initial welding path program of a welding robot, and extracting welding point coordinates and welding torch angle information from the initial welding path program. The welding torch angle The information records the rotation angle of the welding torch when it moves along the coordinates of the welding spot, optimizes the welding path of the welding torch according to the information of the welding torch angle, and takes the shortest welding path of the welding torch selected based on the information of the welding torch angle as the optimal welding path. According to the optimal welding path obtained by this method, the actual welding sequence of the robot can be re-planned, which can improve the welding efficiency of the welding robot, and at the same time avoid frequent large-angle changes in the posture of the welding torch and the cables connected to the welding torch during the welding process, extending the welding torch. and cable life.

Description

technical field [0001] The invention belongs to the field of welding robots, and in particular relates to an optimization method for a robot welding path. Background technique [0002] Robot welding has the advantages of high welding efficiency, stable welding quality, and low work intensity, and has been widely used in the field of industrial automation. But at present, robot automatic welding is not perfect in terms of welding path planning. Technicians often use experience to plan path, but this easily leads to unreasonable robot welding operation sequence, which reduces welding efficiency. Moreover, as the number of welding points increases, It is difficult to find the optimal welding path through experience alone, which increases the tact time of the entire welding process and prolongs the production cycle of the production line. In addition, for welding operations with complex working conditions, when the welding path planning is unreasonable, the posture of the weldi...
