A laser engraving machine for non-metallic materials

Abstract

The invention relates to the technical field of laser cutting, and discloses a non-metallic material laser engraving machine, which includes a negative electrode sheet electrically connected to a negative electrode terminal of a battery case, and a positive electrode sheet electrically connected to a positive electrode terminal of the battery case. Negative charge on the negative electrode and positive charge on the positive electrode. Because the free electrons in the air are attached to the dust, the dust can float in the air. When the dust is close to the negative electrode with negative charge, the principle of same-sex repulsion Repel the dust in the air and prevent it from entering the interior of the first casing and the surface of the focusing lens. On the other hand, the positive charge of the positive electrode can absorb the nearby dust in advance, and because there is no near the positive electrode, it can enter the second casing. In this way, the dust attached to the surface of the positive plate cannot affect the interior of the second casing, which avoids the problems of low laser focusing efficiency caused by dust entering the interior of the laser generator and unqualified products caused by cutting edges.

Description

Technical field [0001] The present invention relates to the technical field of laser cutting, in particular to a non-metallic material laser engraving machine. Background technique [0002] In the field of cutting, laser cutting gradually replace the traditional mechanical cutting, using a high power density beam is irradiated with a laser cutting the material, the material is quickly heated to vaporization temperature and evaporated to form a hole, as the material of the light beam is moved continuously forming holes narrow kerf width, complete the cutting of the material, the cut surface of the laser material is often very flat, no burrs left after mechanical cutting, laser cutting and fast speed, can be moved in a short time a high frequency, with speed, low noise, and low power consumption. [0003] Laser cutting machine laser generator is the most critical parts, must be kept clean and the laser generator and the laser focusing lens, once attached will cause the scattering o...
