基于机器视觉的药用铝箔印刷品质检测系统

摘要

In order to adapt to strict requirements of the pharmaceutical industry for quality of medicinal aluminum foil when printed, a print quality detection system for medicinal aluminum foil based on machine vision was developed after analyzing the detection requirements for ti-ny pinhole defects, words defects on the front side and small foreign body on the back side. A high real-time, high-definition image acquisition environment is built by the linear array CCD camera, bar-shaped LED light source and other necessary hardware. The architecture of the detec-tion system is based on WinSock network communication; the processing results of the multiple industrial computers are transmitted to the central control system through the network communication. The test shows that the detection system can run stably and efficiently in the field and it can improve the automation degree of the print quality detection of medical aluminum foil.%为适应制药行业对药用铝箔印刷品质的严格要求，在分析了印刷过程中对微小针孔、正面文字缺陷以及反面细小异物的检测需求后，开发了一套基于机器视觉的药用铝箔印刷品质检测系统。系统选配了线阵 CCD相机、条形 LED 光源等硬件，搭建了高实时性、高清晰度的图像采集环境；采用基于 WinSock 网络通信的系统架构作为检测软件，将多台工控机的处理结果通过网络通信传输给中控系统。经测试表明：此检测系统在现场能够稳定、高效运行，提高了药用铝箔印刷品质检测的自动化程度。
