【摘要】：随着信息自动化技术的发展,科学技术对传统产业的技术改革不断深化,各种自动化先进装备相继面世,技术密集型产业终将取代资本密集型和劳动密集型产业。作为典型的劳动密集型电热器生产制造业,面临着严峻的考验。人工检测电热管存在多种弊端,难以满足日产量的需要。为提高生产效率,改进生产技术,利用现代自动化技术研发一种检测设备对电热管电参数、尺寸参数智能检测及其分选。针对这一需求,研发电热管自动检测线,设计检测线上料系统、检测系统、分选系统,以实现电热管参数的自动检测与分选。在剖析检测线分选工艺流程的基础上,设计一套以可编程控制器(Programable Logic Controler简称PLC)为主控单元,引入触摸屏技术的控制系统。结合检测线的机械结构,分析输入、输出信号,搭建控制系统结构,利用三菱编程软件GX Developer和GT Designer编写顺序功能图(Sequential Function Chart简称SFC)控制程序和设计人机界面,实现电热管的自动检测和分选控制。最后,完成电热管自动检测线的安装调试以及测试工作,并对检测误差进行分析修正。研究综合运用了PLC、触摸屏、步进驱动器、步进电机、气缸、电磁阀等现代控制元器件,实现了以PLC为核心的电热管自动检测和分选。对机电气一体化技术的综合应用进行了有益的探索。应用实践表明,电热管自动检测线运行稳定、可靠、工作效率高。
[Abstract]:With the development of information automation technology, the technological reform of traditional industries has been deepened continuously, and various kinds of advanced automation equipment have emerged one after another, and technology-intensive industries will eventually replace capital-intensive and labor-intensive industries. As a typical labor-intensive electric heater manufacturing industry, it faces a severe test. There are many disadvantages in manual detection of electric heating tube, which is difficult to meet the demand of daily output. In order to improve the production efficiency and improve the production technology, a kind of intelligent detection and sorting of electric parameters and dimension parameters of electric heating tube is developed by using modern automation technology. In order to realize the automatic detection and sorting of the parameters of the electric heating tube, a feeding system, a testing system and a sorting system are designed to meet this demand. On the basis of analyzing the separation process of testing line, a set of control system with (Programable Logic Controler (Programmable Logic Controller) as main control unit and touch screen technology is designed. Combined with the mechanical structure of the inspection line, the input and output signals are analyzed, and the control system structure is built. The control program and the man-machine interface are designed by using the Mitsubishi programming software GX Developer and GT Designer to compile the sequence function diagram (Sequential Function Chart for short. The automatic detection and sorting control of the electric heating tube are realized. Finally, the installation and debugging of the automatic test line of the electric heating tube and the test work are completed, and the error of the test is analyzed and corrected. Modern control components such as PLC, touch screen, step driver, step motor, cylinder, solenoid valve and so on are used to realize the automatic detection and sorting of electric heating tube based on PLC. The comprehensive application of mechanical and electrical integration technology is explored. The application practice shows that the automatic test line of electric heating pipe runs stably, reliably and with high working efficiency.
