Problems solved by technology

Since the movement of the welding head on the existing laser welding robot is synthesized by a series of rotary rotations, it is very difficult to perform small straight-line welding on some sheet metals, especially for crisscross straight line seams. Doing a series of synthetic movements consumes a lot of energy and has low movement precision

Abstract

The invention belongs to the field of welding robots, and specifically discloses a multi-direction welding head for a laser welding robot. The multi-direction welding head comprises a laser nozzle and a rectangular swinging drum; the laser nozzle is located within the rectangular swinging drum; mounting bases are arranged on two opposite sides of an inner wall of the rectangular swinging drum; a first main electromagnet and two auxiliary electromagnets are arranged on each mounting base, and the two auxiliary electromagnets are symmetrical relative to the first main electromagnet; second main electromagnets are mounted on the other two side surfaces of the inner wall of the rectangular swinging drum; an annular magnet is mounted on a tail of the laser nozzle and located within a magnetic field cavity formed by the first main electromagnets and the second main electromagnets; an elastic piece is arranged on each first main electromagnet; anti-collision columns are arranged on the first main electromagnets and the second main electromagnets. A welding robot provided with the multi-direction welding head for the laser welding robot is relatively low in energy consumption relative to a welding robot provided with a traditional welding head when crisscross tiny straight joints are welded.

Description

technical field [0001] The invention relates to the field of welding robots, in particular to a multi-directional welding head for a laser welding robot. Background technique [0002] Welding is a necessary process in modern machinery manufacturing and is widely used in automobile manufacturing. With the advancement of science and technology, the welding of coated steel plates and light metal materials poses new challenges to automobile welding. Robotic and automated laser welding technology in the automotive welding process has greatly changed the face of automotive welding. With the rapid development of the automobile industry, laser welding technology has opened a new era of automobile welding. [0003] Different from the current traditional spot welding process, laser welding can achieve molecular bonding between two steel plates. Generally speaking, the hardness of the welded steel plate is equivalent to that of a whole steel plate, thereby increasing the strength of ...
