Abstract

The invention provides a robot initial welding position recognition system based on monocular vision sensing, including a welding robot; The main control computer receives the shooting permission signal sent by the welding robot, and then controls the monocular vision sensing system to take pictures of the welding seam scene, and processes the pictures taken, and guides the welding according to the processing results. The robot reaches the starting point of the weld seam. The invention can more flexibly and conveniently take and process images of workpieces to be welded through the monocular vision sensing system. The complex steps of binocular vision sensor installation and calibration are omitted, and the limitation that contact sensing can only be used for workpieces with regular shapes is avoided.

Description

technical field [0001] The invention relates to a guidance control system and method for an arc welding robot, in particular to an initial welding position recognition system and method for an arc welding robot. Background technique [0002] In the welding process, the traditional teaching reproduction welding robot has very strict requirements on the stability of the welding operation conditions, lacks flexibility during welding, has low programming efficiency for welds with complex shapes, and cannot realize real-time detection and control of the dynamic process of welding , unable to meet the high-quality and high-precision welding requirements for complex weldments. In order to overcome the influence of various uncertain factors on the welding quality, the welding robot system is required to have the function of real-time detection and adjustment control. By assembling various sensing devices on the welding robot, it has a certain perception ability to the external envir...
