Description

Intelligent laser engraving control system

Technical Field

The invention relates to the technical field of laser engraving, in particular to an intelligent laser engraving control system.

Background

The laser engraving is based on the numerical control technology, and laser is a processing medium. The physical denaturation of the processing material due to instant melting and gasification under the irradiation of laser engraving can enable the laser engraving to achieve the purpose of processing. The laser engraving is to use laser technology to engrave characters on the object, and the characters engraved by the technology have no nick, the surface of the object is still smooth, and the handwriting is not worn.

Laser engraving has the following advantages:

1. the range is wide: the carbon dioxide laser can be used for carving and cutting almost any non-metallic material;

2. safe and reliable: by adopting non-contact processing, the material can not be subjected to mechanical extrusion or mechanical stress, no 'tool mark' exists, and the surface of a machined part is not damaged; the material is not deformed;

3. and (3) precise and meticulous: the processing precision can reach 0.02 mm;

4. saving and protecting the environment: the diameters of light beams and light spots are small, and are generally less than 0.5 mm; the cutting process saves materials, and is safe and sanitary;

5. the effect is consistent: ensuring that the processing effects of the same batch are completely consistent;

6. high-speed and quick: the high-speed carving and cutting can be immediately carried out according to the pattern output by the computer;

7. the cost is low: without the limit of the number of processing, laser processing is cheaper for small-lot processing services.

But in the course of working, the laser head can produce a large amount of heats, if the life that can influence the laser head is not dispelled the heat in time, and the processing material in engraving process, can produce the smoke and dust, these smoke and dust have toxicity mostly, bring injury to a certain extent to the operating personnel health, and have a small amount of smoke and dust can with laser head direct contact to influence sculpture effect.
