【摘要】：针对在空气环境下金属表面激光标记时,会出现热影响区较大,飞溅物易沉积影响加工质量,同时产生废气和悬浮颗粒,对环境有污染等问题提出了水辅助条件下进行激光标记二维条码的方法。首先,从条码质量评定指标的角度,研究了水层深度对条码图像质量的影响,然后,对比分析了在两种环境下的条码图像质量情况。结合微观分析,证明了水辅助激光标记二维条码的可行性,并且能够解决空气环境下产生的问题。最后,通过设计正交试验和方差分析对水辅助条件下激光加工参数与条码评定指标的关系进行了分析,并进行了参数优化。
[Abstract]:When the metal surface is labeled by laser in the air environment, the heat affected area will be larger, the spatter will easily affect the processing quality, at the same time, the waste gas and suspended particles will be produced. The method of laser marking 2-D barcode under water-assisted condition is put forward. Firstly, the influence of depth of water layer on the quality of barcode image is studied from the point of view of bar code quality evaluation index. The image quality of bar code in two environments is compared and analyzed. Combining with microscopic analysis, the feasibility of water assisted laser marking two-dimensional bar code is proved, and the problems in air environment can be solved. Finally. The relationship between laser processing parameters and bar code evaluation index under water-assisted condition was analyzed by designing orthogonal test and variance analysis, and the parameters were optimized.
