Problems solved by technology

[0005] In addition, laser welding torches are generally used for welding operations by hand. The heat dissipated by the laser backlight and the heat generated by the laser when the welding torch is in use will be transferred to the handle on the welding torch shell under the action of heat conduction, affecting the laser welding torch. reliable control of
[0006] Most of the cooling of existing laser welding torches is carried out by water cooling, which cannot effectively cool the galvanometer motor. Although there are air-cooled laser welding torches, the air-cooled laser welding torch is only simple internal ventilation and cannot achieve good heat dissipation. effect, and it is difficult to guarantee the long-term use of the laser welding torch

Abstract

The invention relates to a laser welding gun which comprises a welding gun body and a galvanometer motor installed on the welding gun body, and the welding gun body is connected with a protective cover of the galvanometer motor. An air cooling assembly used for directly blowing and cooling the protective cover is installed on the protective cover, and heat dissipation assemblies are arranged on the welding gun body and the protective cover. The protective cover connected to the welding gun body can play a good role in protecting the galvanometer motor, return light heat received by the welding gun body is prevented from being transmitted to the galvanometer motor, the air cooling assembly is installed on the protective cover of the galvanometer motor, and the heat dissipation assembly is arranged on the welding gun body and the protective cover. And the overall heat dissipation effect of the laser welding gun can be enhanced.

Description

technical field [0001] The present application relates to the technical field of laser welding, in particular, to a laser welding torch. Background technique [0002] In the field of laser welding, laser welding torch, as a hand-held laser welding equipment with simple structure and convenient operation, has attracted more and more attention. [0003] Laser welding torches generally carry out welding by emitting laser light, including the vibrating mirror motor and the laser vibrating mirror connected to the vibrating mirror motor. By inputting a position signal to the vibrating mirror motor, the vibrating mirror motor will convert according to a certain voltage and angle. The ratio swings at a certain angle, thereby driving the laser galvanometer to change the route of the laser light so that the laser light is emitted. [0004] The stability of the galvanometer motor during operation is very important. During the use of the laser welding torch, the heat of the returned li...
