Description

A platform type laser engraving machine

technical field

The utility model relates to a platform type laser engraving machine, in particular to a platform type laser engraving machine utilizing a Quantum Cascade Laser (Quantum Cascade Laser) output device arranged on a working platform or a pen carriage to replace Carbon dioxide laser tubes reduce or even eliminate the use of reflectors, and effectively reduce the distance of the optical path to avoid loss of laser wattage.

Background technique

Usually, the basic principle of the laser engraving machine is to guide and focus the beam output by the laser onto the surface of the object to be engraved. After the focused beam is absorbed by the material, the temperature suddenly rises and gasifies, making the surface of the object concave. To achieve the purpose of engraving and cutting, the process of using laser engraving is very simple, just like using a computer and printer to print on paper. Under the Win95/98 environment, a variety of graphics processing software, such as CorelDraw, can be used to design. Scanned graphics, vectorized graphics and various CAD files can be easily "printed" to the engraving machine. The only difference is that general printing is to apply toner to paper, while laser light engraving is to output laser light onto almost all materials such as wood, acrylic, plastic sheet, metal sheet, stone, etc.

The carbon dioxide laser tube used in today's laser engraving machines must be installed inside the machine due to the large volume of the tube, and then through the setting of several reflectors, the laser light path can be transmitted to the platform through the reflectors. On the pen car, the entire transmission distance is too long, which often leads to the loss of laser wattage, and the laser spot size is different due to different optical path distances. Overall, the efficiency of use is not ideal. At the same time, the reflective The adjustment, installation and dust-proof treatment of the mirror must consume manpower and material resources, and the cost must be borne by the user.
