Abstract

According to a robot capable of adjusting welding height through an arc voltage heightening system and a welding method, the length of a collected arc is converted into data information to be fed backto a robot control module, the robot control module adjusts the posture of the robot according to the fed-back data information, and arc voltage is kept stable and consistent during automatic weldingoperation of the robot. The robot comprises a robot body provided with a welding machine, a workpiece to be welded, a robot locating module, a high-voltage contactor module, wherein the robot locating module is used for locating the robot; the high-voltage contactor module is used for controlling on-off of a main loop of the welding machine. The robot further comprises a welding arc voltage heightening system and a robot control module which are used for accurately sampling the arc voltage of the welding machine and conducting digital algorithm processing, and after proper arc voltage data are obtained, the arc voltage data are uploaded to the robot control module to act.

Description

technical field [0001] The invention relates to the technical field of robot welding, in particular to a robot and a welding method for adjusting the welding height through a welding arc voltage adjustment system. Background technique [0002] At present, the existing arc voltage adjustment devices are all aimed at cutting and traditional argon arc welding. The arc voltage acquisition is processed by a simple analog circuit, the sampling accuracy is low, and there is no dedicated interface for robot communication. In the robot welding process, the accuracy of arc voltage control is high, especially to meet the requirements of stable and consistent arc length, good dynamic performance, and rapid communication response. In the case of cutting and welding with low requirements, the control can still meet the process requirements, but when accurate and stable welding is required, due to the limited sampling and control, the arc length is difficult to stabilize, and the arc will ...
