High-precision robot automatic welding device special for grid plate and working method thereof

Abstract

The invention discloses a high-precision robot automatic welding device special for a grid plate. The high-precision robot automatic welding device special for the grid plate comprises a fixed base, a rotating shaft, a lower arm, an upper arm, a wrist joint and an electric control box, wherein the rotating shaft is arranged on the fixed base; the lower arm is connected with the rotating shaft through a positioning pin; the upper arm is connected with the lower arm through a positioning pin; the wrist joint is connected with the upper arm through a positioning pin, and a welding gun and a camera device are arranged at one end of the wrist joint; cameras are arranged in the camera device; the rotating shaft, the lower arm, the upper arm, the wrist joint and the camera device are all electrically connected with an electric control box. According to the high-precision robot automatic welding device special for the grid plate, the camera device is arranged in the automatic welding device; the grid plate which is required to be welded is shot through three groups of cameras; the images shot by the cameras are subjected to data processing and analyzing through a control system in a control device; the type of the grid plate which is required to be welded, a position which is required to be welded and the welding quality are known precisely, so that the welding precision of the automatic welding device is greatly improved.

Description

technical field

[0001] The invention belongs to the field of production and manufacturing, and in particular relates to a high-precision robot automatic welding device for grid plates 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...
