 摘  要
 
 21世纪是电子信息的时代，VFD（真空荧光显示屏）产品越来越多的出现在工业现场和我们的生活中。而在VFD生产中，印制电路板如何进行精确定位打孔成为一大难题。本课题主要是设计一个用于VFD生产中精确定位打孔的数控打孔机控制系统。
 本文首先对我国数控技术的发展现状和VFD生产领域中数控打孔机的产生、发展前景及所面临的主要问题进行了详细的分析；其次根据定位打孔的工艺要求和性能指标，给出了系统的总体设计。本系统以松下PLC的FPX C30T为控制器，松下触摸屏GT32作为人机界面，采用伺服驱动技术、变频器无级调速技术对伺服系统与变频器进行控制。同时介绍了松下电工的FPX C30T PLC的组成及其主控模块和I/O模块的规格。然后在此基础上详细阐述了系统的硬件设计，包括控制器和人机界面的设计；最后介绍了系统的软计设计，并详细解说了控制系统和人机界面的软件设计方法,进行了系统实验调试。
实验运行结果符合生产实际要求，系统满足精度和工艺的要求，对产品的质量和稳定性有一定的提高。

The 21st century is the era of electronic information, more and more VFD (Vacuum Fluorescent Display) appeared in the industrial field and our lives. But in the VFD production, how to precisely locate drilling becomes a major problem .this issue is to design a precise positioning system which is controlled by NC Technology for drilling VFD  production .
First, this thesis gave a detailed analysis about the current situation of NC technology in China and the background and the prospects of development and the main problems facing of NC Drilling Machines in VFD production; Second, this paper introduced the total design of the system based on technologic requirements and functional target. The system controller for the PLC to Matsushita Panasonic touch screen GT32 as a human-computer interface, a servo-driven technology, drives stepless speed regulation technology, Drives stepless speed regulation technology to servo control system and inverter. This paper introduced the composition and the main control module and I / O module specifications of  FPX C30T  PLC. Then elaborated the hardware design of the system under the top of foundation, include the design of the controller and human machine interface. Finally, this paper introduced the design of system software , and explained the designing method of control system and human machine interface in detail ,and Carried out experiments to debug the system.
Experimental results in line with the practical requirements of production, systems and processes to meet the accuracy requirements of product quality and stability have improved.
