【摘要】：丝网印刷技术,承印物形状、承印物大小对它的限定有限,并且适应多种不同特性的油墨、耐旋光性能强、印刷方式灵活多样、印刷中可以选用多种不同厚度的油墨层来印刷,因此,很有必要研究出高端的丝网印刷设备。本文更是结合了企业的生产情况以及市场上丝网印刷机的发展趋势和需求状况,利用了成熟的可编程逻辑控制器控制和终端控制技术,在已有的设备的基础上对设备进行性能的批量优化。本文在对汕头超声公司定制的550新型丝网印刷机控制系统进行分析的基础上,对其硬件部分做了大量的改进和详细的设计。包括PLC装置、人机交互界面、功能模块等以及电路原理图的设计。对测厚装置、触摸屏以及视觉对位系统和PLC通信接口进行了详细的设计。对跑台位置的控制方面,利用交流伺服驱动系统来实现跑台对玻璃的准确传送。在软件设计层面,本程序分为以下四个部分:主程序、视觉程序、手动程序和参数程序。按照模块化的编程思想,对各个主要模块进行了较为详细的描述。在人机交互界面,利用GP-Pro EX 4.0开发出触摸屏中的各种功能界面,可操作性得到提高。本文所论述的控制系统,经过了实验与现场调试之后,满足了控制系统的各项要求,运行稳定且能达到预期目标。
[Abstract]:Screen printing technology, substrate shape, substrate size limited to it, and adapt to a variety of different characteristics of ink, strong optical resistance, flexible and diverse printing methods, printing can be used in the printing of a variety of different thickness of ink layer to print, Therefore, it is necessary to develop high-end screen printing equipment. This paper combines the production situation of the enterprise, the development trend and demand of the screen printing machine in the market, and makes use of the mature programmable logic controller control and terminal control technology. On the basis of the existing equipment to optimize the performance of the equipment batch. Based on the analysis of the control system of the 550 new screen printing machine customized by Shantou Ultrasonic Company, this paper makes a lot of improvement and detailed design on its hardware part. Including PLC device, man-machine interface, functional modules and circuit schematic design. The thickness measuring device, touch screen, visual alignment system and PLC communication interface are designed in detail. The AC servo drive system is used to realize the accurate transmission of the running table to the glass. In the software design level, the program is divided into the following four parts: main program, visual program, manual program and parameter program. According to the modular programming idea, the main modules are described in detail. In the man-machine interface, various functional interfaces in touch screen are developed by using GP-Pro ex 4.0, and the maneuverability is improved. The control system described in this paper has met the requirements of the control system after experiment and field debugging, and it can run stably and achieve the expected goal.
