Abstract

The invention discloses a method for controlling a mechanical arm to perform automatic welding. The method includes the following steps that positions of a plurality of rotary joints connected with the mechanical arm are determined; the position of an end effector of the mechanical arm is determined; the end effector of the mechanical arm is controlled to plan an welding angle and a welding track of a workpiece to be welded according to the positions of the rotary joints and the position of the end effector; the end effector of the mechanical arm is controlled to weld the workpiece. According to the method for controlling the mechanical arm to perform automatic welding, welding operation can be automatically controlled through operation of the mechanical arm, so the labor intensity of workers is relieved, the overall welding quality of the workpiece is superior to manual welding, and dimension stability of each workpiece is high.

Description

technical field [0001] The invention relates to a welding robot, in particular to a method for controlling automatic welding of a manipulator. Background technique [0002] The current welding generally uses manual welding. Manual welding technology requires welders to have a proficient level of operation, sufficient practical experience, and can only operate after obtaining a welding qualification certificate. The working environment of welding is also poor, with large dust particles. And more, light and heat radiation irritate people's skin and eyes, the risk is higher than other industries, harmful to human health, manual welding production efficiency is not very high, and the overall welding quality of manual welding workpieces is relatively low, for a single Workpiece dimensional stability is low. Contents of the invention [0003] The purpose of the present invention is to provide a method for controlling the automatic welding of manipulators to solve the problems i...
