High-precision automatic robot welding device and working method thereof

Abstract

The invention discloses a high-precision automatic robot welding device for grid plate welding. The high-precision automatic robot welding device comprises a base, a mechanical arm, a wrist joint, a touch screen and a control device, wherein a laser detector and a welding gun are arranged on the wrist joint; the mechanical arm is arranged on the base; the wrist joint is arranged at the end part of the mechanical arm; the touch screen is arranged on a supporting frame of the base; the mechanical arm, the wrist joint, the touch screen and the laser detector are all connected with the control device; an electric control box is arranged in the control device; and the detection range of the laser detector is greater than or equal to the width of a welding edge required by a grid plate. According to the high-precision automatic robot welding device, the mounting base is arranged on the wrist joint; the mounting base is inversely L-shaped; a first mounting hole for mounting the laser detector and a second mounting hole for mounting the welding gun are formed in the mounting base; the first mounting hole is higher than the second mounting hole, so that damage to the laser detector during welding of the welding gun is avoided; and meanwhile, the high-precision automatic robot welding device can effectively guarantee detection of the laser detector in the whole process.

Description

technical field [0001] The invention belongs to the field of grid plates, and in particular relates to a high-precision robot automatic welding device and a working method thereof. Background technique [0002] Steel grating carbon dioxide gas is mainly used for edge sealing of steel grating. Most welding companies still use manual welding for welding. The workload is very heavy. At the same time, due to the large number of people in the welding process Most of them are welded with the naked eye, and the quality of the welding is not stable enough. Due to the poor controllability of people, it is difficult to keep the quality of the welding consistent. Because the welding points are relatively dense, the technical requirements for welding workers are high. The matching of position and parameters is not easy to maintain the best. During the welding process, problems of false welding and missing welding often occur, and the gas generated during the welding process will cause c...

AI Technical Summary

Problems solved by technology

At present, many enterprises use robots for welding, and the cost is relatively high. Because the welding operation of steel grid plates is too cumbersome, and it is not a special customization of welding products, some processes are difficult or impossible to complete. The existing There will be a lot of metal dust in the production environment of steel grating, and the detection devices such as sensors will cause inaccurate detection due to the influence of smoke and dust during the processing, which will seriously affect the detection effect of the detection device, thus affecting its welding quality. Quality, which will put higher requirements on the automatic welding device, so the welding technology of the existing steel grating needs to be improved
