Embodiment Construction

[0021] The invention provides a welding robot system with simple structure, low cost, simple control mode and high reliability:

[0022] A welding robot, including a mechanical arm, a cage fixed at the end of the mechanical arm 1, a welding torch 2 installed on the end of the mechanical arm 1, an error correction system and a line inspection system installed on the cage, according to the instructions of the control system , the mechanical arm drives the welding torch 2 to be located above the seam and move along a predetermined path to complete the welding of 3 / 4 of the two plates;

[0023] The line inspection detection system includes at least three sensors 7 located on the plane formed by the axis of the welding torch and the seam; figure 2 , taking five sensors 7 as an example, the five sensors 7 are equidistantly arranged in the width direction of the seam, preferably the total length of the five sensors is greater than the width of the seam; the sensors are connected to t...

Abstract

The invention relates to a welding robot which comprises an error correction system and a line patrol detection system. A welding gun welds two parallel plates along a pre-defined path under the control of a mechanical arm. Moreover, the position and posture of the welding gun are detected and adjusted in real time, and therefore the welding gun is always positioned over a welding seam. The welding robot ensures the welding quality and the welding effect and has the advantages of simple structure, low cost, simple control mode and high reliability.

Description

technical field [0001] A welding robot, especially a welding robot system with an error control system. Background technique [0002] A welding robot is a mechanical device that completes welding operations under the control of an automatic controller. The welding robot has reliable welding quality, high precision, and good environmental adaptability. Therefore, the application of robot welding is becoming more and more extensive and common. [0003] In order for the robot to complete the welding work along the predetermined welding path, the predetermined program must be set in advance. However, due to various errors such as control errors and mechanical errors, there is a certain gap between the actual welding path of the robot and the predetermined welding path. Welding errors; in high-precision welding occasions, through various sensors or control algorithms to minimize welding errors as much as possible. Based on this, aiming at the high cost and complicated control of...
