Abstract

The invention relates to a welding seam positioning method and system based on a visual guidance robot. The method comprises the following steps: acquiring image information of a to-be-welded workpiece; according to the image information, determining the initial position of a welding seam of the to-be-welded workpiece; and according to the determined initial position of the welding seam, guiding a welding seam robot to weld. According to the technical scheme, the image information of the to-be-welded workpiece is obtained by the visual method, the initial position of the welding seam of the to-be-welded workpiece is determined through image processing, and the welding seam robot is guided to move to the initial position of the welding seam for welding. In the whole welding operation process, manual intervention is not needed, the welding efficiency is high, and the user experience degree is good.

Description

technical field [0001] The invention relates to the technical field of intelligent welding, in particular to a method and system for positioning a welding seam of a robot based on vision guidance. Background technique [0002] Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization (ISO) that industrial robots belong to standard welding robots, an industrial robot is a multi-purpose, reprogrammable automatic control manipulator (Manipulator) with three or more programmable axes for field of industrial automation. In order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is equipped with a welding tongs or a welding (cutting) torch on the flange of the final axis of the industrial robot, so that it can perform weld...
