激光直接标刻二维条码技术在香蕉表面上的应用研究
Study of Laser Marking Two Dimensional Barcodes on Banana Surfaces
摘要
随着全球对食品安全性重视的提高, 对水果实现产品追溯成为必然要求。目前, 对于水果追溯大都是通过在水果表面粘贴纸质标签实现, 然而, 由于纸质标签粘贴强度稳定性差, 有些容易脱落, 造成信息丢失; 有些又难以去除, 给广大消费者带来麻烦。针对此问题, 利用激光技术在水果表面直接标刻二维条码成为新的研究热点。为此, 本文以香蕉为研究对象, 利用CO2-S100XP激光器在香蕉表面标刻Data Matrix(DM)二维条码, 研究了直接标刻二维条码在香蕉表面应用的可行性, 分析了激光参数对二维条码颜色和对比度的影响, 同时, 分析了影响条码识读的各个因素。实验表明: 激光功率和标刻速度是影响条码质量主要因素; 香蕉划痕、黑斑和标刻位置会影响条码的质量和条码的识读。
Abstract
With the increasing attention to food safety, it is necessary for us to trace the fruit. At present, the most widely used method is to stick paper label to the surface of apple. But the paper label has bad paste strength stability. Sometimes they are easy to fall off, causing the loss of information. Sometimes they bring trouble to consumers because of the difficulty of removal. To address this problem, laser marking of two dimensional symbols on the surface of fruits becomes a new research focus. In this paper, experiments of laser marking Data Matrix symbols on surfaces of bananas were carried out by using CO2-S100XP laser and the feasibility of laser marking two dimensional barcodes on banana surfaces was further studied. Influence of processing parameters on qualities(color and contrast)of Data Matrix symbols was analyzed and the key factors that affect the barcode decode rate were defined. The experiment results show that laser power and scanning speed are the main factors that influence the barcode quality, the scratches and black spots of banana and the marking location also make a difference.
