Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ...

Abstract

The invention relates to a laser welding device which comprises a laser emission main body, a laser emission device, a heat dissipation part, a cooling channel and a support seat, wherein an emission cavity is formed in the laser emission main body; the emission cavity is provided with an opening; the laser emission device is arranged at the end, far away from the opening, in the emission cavity and faces the opening; the heat dissipation part is connected with the laser emission main body; the cooling channel penetrates through the interior of the laser emission main body and is provided with a cooling valve; and the support seat is fixedly arranged in the emission cavity and fixedly connected with the laser emission device. Since the cooling channel and the heat dissipation part simultaneously dissipate heat of the laser emission main body, heat generated by the laser emission device is efficiently dispersed and the service life of the laser welding device is prolonged effectively.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser welding device. Background technique [0002] Laser has the characteristics of strong directionality, high brightness, and high focusing temperature. It is often used in laser welding devices for welding between metals. Laser welding has the characteristics of high efficiency, but due to the high focusing temperature of lasers, often Laser emitters generate a lot of heat, for example, high-power laser welding equipment, the energy of the laser is extremely high during operation, if the heat is not evacuated in time, the service life of the laser welding equipment will be greatly reduced. Contents of the invention [0003] Based on this, it is necessary to provide a laser welding device with better heat dissipation effect for the large amount of heat emitted by the existing high-power laser welding device when it is working. It is beneficial to extend the life of the lase...
