Problems solved by technology

The existing laser engraving module uses the airflow generated by the axial flow fan to exchange heat with the open cooling teeth on the surface of the radiator to achieve heat dissipation, but the airflow decays quickly in the open space, the heat dissipation effect is not good, and the smoke and dust generated by engraving cannot be removed in time. Blowing away, the lens and engraving workpiece at the light outlet of the module are easily polluted, and the engraving effect is not good; in addition, the existing laser engraving module lacks light-shielding protection when engraving, which is easy to cause harm to the human body

Abstract

The invention discloses a laser engraving module with good heat dissipation and protection effects. The laser engraving module comprises an air collection cover, and a first heat dissipation device, a second heat dissipation device and a laser module which are sequentially arranged from front to back. The first heat dissipation device is connected to the front end of the second heat dissipation device, a plurality of air outlets are formed in the rear end of the first heat dissipation device, and ventilation ducts used in cooperation with the air outlets are arranged on the second heat dissipation device. The laser module is arranged in the second heat dissipation device. The air collecting cover is detachably connected to the rear end of the second heat dissipation device in a magnetic connection mode, an air outlet is formed in the left side wall of the air collecting cover, the upper side wall, the lower side wall and the right side wall of the air collecting cover are light blocking walls, and an air collecting nozzle is arranged at the position, corresponding to the laser module, of the air collecting cover. According to the laser engraving module, the energy loss of airflow is effectively reduced, and the heat dissipation effect is better; and the air collecting cover and the second heat dissipation device are fixed through magnetic connection, so that rapid disassembly and assembly are achieved, the laser module and a workpiece can be effectively prevented from being polluted by smoke dust, and the engraving effect is better.

Description

technical field [0001] The invention relates to the technical field of laser processing applications, in particular to a laser engraving module with good heat dissipation and protection effects. Background technique [0002] Laser engraving technology is a physical processing technology based on numerical control technology and using laser as the processing medium to melt or vaporize processing materials under laser irradiation. At present, a variety of laser engraving modules have been launched on the market, and laser engraving modules The heat dissipation effect of the laser and the removal efficiency of the smoke and dust generated during the processing directly affect the effect of laser engraving. The existing laser engraving module uses the airflow generated by the axial flow fan to exchange heat with the open cooling teeth on the surface of the radiator to achieve heat dissipation. However, the speed of the airflow decays quickly in the open space, the heat dissipati...
