摘要
在工业领域中,具有可追溯性的直接零件标识技术受到越来越多的关注。但是很多产品零部件对于直接零件标识有尺寸要求,限制了信息存储容量。为了提高直接零件标识的数据存储密度,在直接零件标识技术中引入彩色二维条码的概念,设计了一种彩色Data Matrix二维条码直接零件标识。利用纳秒激光标刻设备在钛合金材料上进行标刻实验,成功实现彩色二维条码的激光标刻,并进行质量评估。为了进一步验证条码的可靠性,采集激光标刻二维条码的图像,依照评估结果选择是否在信息提取前进行条码重构,从而校验条码信息。校验结果证明了所加工彩色Data Matrix二维条码是可靠的,彩色直接零件标识技术具有可行性,可以在工业直接零件标识领域进行推广应用。
Abstract
In the field of industry, the technology of direct part marking with traceability has been paid more and more attention. However, many product components have requirements of size restriction for direct part marking, thus the information storage capacity has been restricted. In order to improve the data storage density of direct part marking, the concept of color two-dimensional barcode is introduced into the technology of direct part marking, and the color Data Matrix two-dimensional barcodes are designed by direct part marking. The laser marking experiment of color two-dimensional barcodes on titanium alloy materials are carried out with nanosecond laser marking equipment, and the laser marking of color two-dimensional barcodes are successfully implemented, and barcodes’ qualities are evaluated. In order to further verify the reliability of barcodes, the images of two-dimensional barcodes marked by laser are collected for choosing whether to carry out barcode reconstruction before information extraction according to the evaluation results to verify barcodes information. The verification results prove that the processed color Data Matrix two-dimensional barcodes are reliable, and the color direct part marking technology is feasible, which can be promoted and applied in the field of industrial direct part marking.
