Dot matrix engraving effect evaluation method of laser engraving machine

Abstract

The invention discloses a dot matrix engraving effect evaluation method of a laser engraving machine. The method comprises the steps: determining the approximate minimum identifiable width d; determining a laser engraving standard atlas; performing laser engraving; scoring a laser engraving effect; and determining factors causing poor laser engraving. The method is simple and effective, compared with an existing experiential method, according to the invention, the minimum stripe identification width and the minimum gap identification width are respectively quantified by using the numbers of stripes and gaps in the X-axis direction and the Y-axis direction; therefore, laser engraving quality control, process capability control and product abnormity troubleshooting capability are greatly improved, and daily production and maintenance operation of a laser engraving machine user can be effectively guided.

Description

technical field [0001] The invention relates to the technical field of engraving, in particular to a dot matrix engraving effect evaluation method of a laser engraving machine. Background technique [0002] At present, the dot matrix engraving of laser engraving machine means that the laser head scans back and forth along the positive and negative directions of the X axis. To form a pattern or text, dot matrix engraving is widely used in the printing of graphics and text on some specific plates. [0003] But so far, there are few methods for evaluating the effect of dot matrix engraving and related literature records, or the existing methods are only qualitative and empirical judgments through visual inspection. This judgment method is aimed at laser engraving. Trial printing of graphics or text, and then visual inspection of the trial printed samples. The standard of visual inspection is to judge whether it is clear based on experience, and there is no unified quantitative...

AI Technical Summary

Problems solved by technology

Operators are required to have a certain amount of experience accumulation, otherwise there will be large judgment errors, so the high requirements of empirical judgment on the professionalism of personnel will lead to a waste of human resources

[0006] 2) The consistency of product quality is low, and the probability of misjudgment is high

Due to the lack of unified quantitative indicators, the judgment standards of different operators are quite different, which will lead to low consistency of laser engraving quality, and even misjudgment.

Therefore, empirical judgment will lead to uneven overall quality of laser engraving and low consistency

[0007] 3) It cannot effectively guide the troubleshooting of abnormal laser engraving quality

There are many process variables that affect the quality of laser engraving. When the quality of the laser engraving sample is abnormal, the empirical judgment method is not easy to quickly find the root cause of the abnormality due to the lack of effective analysis objects, and it is not easy to effectively guide the operators to quickly troubleshoot. exclude

[0008] 4) For some products with high requirements for laser engraving quality, it is difficult to achieve the best effect during trial production and debugging

The lack of unified quantifiable indicators and effective analyzable objects makes it difficult to achieve the best laser engraving effect due to the lack of a reliable basis for setting relevant parameters.
