Portable laser carving machine

Abstract

The invention discloses a portable laser carving machine comprising a panel trolley and a display screen. The panel trolley is composed of a horizontal trolley plate, a laser emitter, a control unit and a travelling mechanism, wherein the laser emitter, the control unit and the travelling mechanism are fixed to the lower plate face of the horizontal trolley plate. The display screen is arranged onthe upper plate face of the horizontal trolley plate, and the travelling mechanism comprises an X-direction axle, a Y-direction axle, a first gear transmission mechanism, a second gear transmission mechanism, a first stepping motor, a second stepping motor and universal wheels, wherein the X-direction axle and the Y-direction axle are horizontally arranged, and the universal wheels are mounted atthe two ends of the X-direction axle and the two ends of the Y-direction axle correspondingly. The X-direction axle and the Y-direction axle are rotatably connected with the horizontal trolley platethrough bearing bodies, the X-direction axle is in transmission connection with the first synchronous motor through the first gear transmission mechanism, and the Y-direction axle is in transmission connection with the second synchronous motor through the second gear transmission mechanism. The portable laser carving machine has the advantages that an enormous frame structure of an existing carving machine is omitted, the portable laser carving machine is small and easy to carry, and the adaptability of the portable laser carving machine is improved. Meanwhile, the portable laser carving machine can conduct caving through an existing mature carving upper computer.

Description

technical field [0001] The invention relates to the field of laser engraving processing, in particular to a portable laser engraving machine. Background technique [0002] Laser engraving processing is based on numerical control technology, laser is the processing medium, and the processed material is instantly melted and gasified under the laser irradiation to achieve the processing purpose. The characteristic of laser processing is that it has no contact with the surface of the processed material and is not affected by mechanical movement, so the surface will not be deformed, and the processed material does not need to be fixed. At the same time, it is not affected by the elasticity and flexibility of the processed material, and has high processing precision, fast speed and wide application fields. [0003] When the common laser engraving machine on the market is performing processing operations, the motor drives the screw to rotate, thereby pushing the laser head or the ...

AI Technical Summary

Problems solved by technology

However, because the distance from the laser head to the active surface is constantly changing, if the focal length is not adjusted in real time, it will inevitably cause a lot of waste of energy and affect the engraving effect, and the constantly changing angle between the laser and the active surface will lead to uneven engraving effects in different places

In addition, the engraving machine does not use the commonly used Cartesian coordinate system, so it cannot be used in conjunction with the host computer
