Welding robot control method

Abstract

The invention discloses a welding robot control method, and relates to a welding robot control device. According to the welding robot control method, a laser vision sensing system, a laser barcode scanning system, a main industrial personal computer, a driving device and a wireless demonstration device are utilized. A weldment is scanned through the laser bar code scanning system to form a three-dimensional model, the three-dimensional model is led into the main industrial personal computer, and welding information is directly designated on the three-dimensional model through the wireless demonstration device. The welding information comprises positions and lengths of weld joints, and the swing mode of a welding gun. When welding workpieces needs to be produced in a batch mode, a bar code identification system can be used for reading the welding information of welding bar codes on the welding workpieces, then the welding information is sent to the main industrial personal computer, and the main industrial personal computer converts the information of the bar codes into welding signals. The welding robot control method has the advantages that closed-loop control is realized, demonstration efficiency is improved, control of a welding robot is convenient, the electromagnetic field disturbance resistance ability is high, the demonstration efficiency and the quality of the weld joints of the workpieces are improved, the adaptive ability of a control system is enhanced, and the reliability is high.

Description

technical field [0001] The invention relates to a welding robot control device, in particular to a welding robot control method, a welding robot control method based on wireless intelligent teaching and three-dimensional laser scanning of visual tracking technology. Background technique [0002] Welding robots are industrial robots that replace welders in welding tasks in the field of welding production. They are mainly divided into two categories: spot welding and arc welding. The welding parameters of the existing teaching reproducible welding robots are preset according to the working conditions, lack of external information sensing and real-time adjustment functions in the welding process, have strict requirements on the consistency of working conditions, and cannot adapt to the welding environment and process. Variety. Secondly, the teaching process of the teaching reproduction welding robot is cumbersome, the empty travel time is too long, and the work efficiency is ...
