基于图像模式识别与PLC控制的印刷套准自适应系统

摘要

针对印刷过程的不稳定性,通过对套印标记的图像采集和处理,适时调整纸张张力大小,构建了一种印刷套准无模型自适应系统.该系统通过图像、PLC和组态软件的联合控制,实现了套准标记的自动检测、图像识别和自动校准.利用该系统中的PLC和组态软件还可实现印刷过程的实时监控,便于观察印刷过程的动态特性.该系统用于各类多色印刷设备上,可提高印刷设备的自动化程度.%For the unstable working environment, adjusted the paper' s tension by overprint image acquisition and processing. This paper constructed a set of quasi-model-free adaptive printing system. Automatic detection of registration marks, realized image recognition and automatic calibration by joint control of image, PLC and configuration software in the system. By using PLC and configuration software real-time monitoring could also be achieved, made it easy to observe the dynamic characteris tics of the printing process. The system was used on various types of multi-color printing equipment to increase the degree of automation.
