A programming-free welding robot and its control method

Abstract

The invention discloses a programming-free welding robot and a control method. The welding robot comprises a welding torch, an illuminator, servo motors, encoders, a wrist, a forearm, an upper arm, an engine base, a turntable, a pillar, a base, a grating ruler, a computer and drivers, wherein the servo motor V is arranged inside the pillar, and a gear is connected onto the shaft of the servo motor V and meshed with the rack of the base provided with the grating ruler; the turntable at the upper end of the pillar is connected with the servo motor IV; the engine base and the upper arm, the upper arm and the forearm, as well as the forearm and the wrist are connected through the servo motors respectively; the welding torch, the illuminator and an optical switch are arranged at the front end of the wrist; each encoder is mounted on the corresponding servo motor; the drivers and the encoders are connected with the computer. According to the invention, the welding robot is manually moved to perform the whole set of operations such as moving, welding and returning, and the computer studies and saves all the motion tracks of the welding robot and then copies and inherits the motion tracks, so that the whole process including starting, moving, aligning, welding and returning can be completed; the difficulty that a robot is needed to be programmed is solved, the automatic welding can be implemented, and the operating efficiency and the welding quality are improved.

Description

technical field [0001] The invention belongs to the field of mechanical control, in particular to a welding robot capable of realizing automatic welding without programming and a control method thereof. Background technique [0002] At present, robots have been widely used in various operations and operations in various fields, and have played an irreplaceable role in improving operating efficiency and reducing production costs.
