Laser engraving method

Abstract

The invention provides a laser engraving method, and relates to the field of laser engraving. The laser engraving method comprises the following steps that a, a water pump and an air pump are turned on; b, a host power supply and a fan power supply are turned on; c, a laser power supply is turned on; d, the control software is started to detect whether upper, lower, left and right light heads moveor not; e, workpiece preparation is conducted; f, various properties of laser engraving are adjusted; g, a computer is operated to transmit files, a camera is in signal connection with the computer,and images generated in the engraving process are transmitted back to the computer in time; and i, pictures transmitted back to the computer are compared and analyzed with the original files, and it is detected that whether the laser engraving has an error or not. According to the laser engraving method, through arrangement of the camera, the computer is linked with the working internal conditionof a laser engraving machine, it is guaranteed that the engraving result completely meets the requirements of people, engraving errors do not occur, the whole laser engraving method is clear in thought, a to-be-machined material can be rapidly and accurately machined, it is guaranteed that deviation does not occur in the engraving process, the production cost is saved, and the practicability is high.

Description

technical field [0001] The invention relates to the field of laser engraving, in particular to a laser engraving method. Background technique [0002] With the development of carving art, various carving techniques continue to emerge. At present, there are four main engraving techniques: manual engraving, mechanical engraving, chemical engraving and laser engraving. Manual carving is too inefficient. The scope of application of chemical engraving is more limited and it is easy to cause environmental pollution. Most mechanical engraving devices are limited to the engraving plane, and furthermore, the strength limits of mechanical knives define the minimum knife diameter and thus the stroke width. The laser engraving unit is effective as a universal engraving knife, and its fine stroke width is especially suitable for intricate engraving and engraving on properly formed surfaces. Since laser engraving is a non-contact process, there will be no problems similar to mechanica...

AI Technical Summary

Problems solved by technology

Improper selection of strength and speed often leads to poor engraving effect: either the definition is not enough, or the engraving material is melted and the pattern is distorted

In addition, traditional laser engraving methods are difficult to engrave patterns with grayscale and color gradients and layered effects
