High-precision automatic robot welding device and working method thereof

Abstract

The invention discloses a high-precision automatic robot welding device, which comprises a fixing seat, a horizontal shaft, a first joint shaft, a second joint shaft, a first position sensor, a second position sensor, a welding gun and a control device, wherein the control device comprises a welding device, a sensor control module, an execution device, an alarming system and an automatic control system; the first position sensor and the second position sensor are arranged on the second joint shaft and are connected with the sensor control module; and the horizontal shaft, the first joint shaft and the second joint shaft form an arm of the robot. According to the high-precision automatic robot welding device, the first position sensor and the second position sensor are arranged on the arm of the robot, the position of a welding point is calculated via detection values of the two sensors, automatic calibration of the welding position is realized, accuracy of the welding gun position and the welding port position can be effectively ensured, accuracy of the welding position is greatly improved, and stability of the welding quality is ensured.

Description

technical field [0001] The invention relates to a welding device, in particular to a high-precision robot automatic welding device for welding 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 certain h...

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, most of the existing general-purpose robots are configured in 4-axis to 7 weeks, which will not only increase the welding cost. The action in the process leads to lower welding efficiency. Because it is not customized for welding products, some processes are difficult or impossible to complete. At the same time, because its structure is too complicated, more parts used will increase its production cost. , so the existing steel grating welding technology still needs to be improved. At the same time, the existing robot welding must be taught before use. Because the teaching process is too long, some teaching processes Even several times of the whole welding process, in the small batch production process, often appear in workpieces with a large number of welding points, so the existing robot welding technology still needs to be improved
