1、 I 机械手 PLC 控制系统设计 摘 要 随着微处理器、计算机对数字通信技术的飞速发展，计算机控制已扩展到了 几乎所有的工业领域。现代社会要求制造业对市场需求作出迅速的反应，生产出 小批量、多品种、多规格、低成本和高质量的产品。为了满足这一要求，生产设 备和自动生产线的控制系统必须具有极高的可靠性和灵活性。可编程序控制器正 是顺应这一要求出现的，它是以微处理器为基础的通用工业控制装置。本文介绍 了 FX2n系列可编程控制器对机械手的控制，包括 PLC 和 I/0 的分配图和接线图， 运用限位开关与 PLC 程序配合，以驱动机械手按其工艺流程完成工作。由于 PLC 所具有的灵活性、模块化、易于

2、扩展、及其可靠性等特点，可以根据现场要求， 实现机械手的不同工作要求。 关键词：PLC ，限位开关，可靠性，自动化 II Manipulator PLC control system design ABSTRACT As a microprocessor, a computer to the rapid development of digital communication technology, the computer control system has been extended to almost all of the industrial field. Modern societ

3、y demands of market demand manufacturing respond immediately to produce small batch, many varieties and specifications, low cost and high quality products. In order to meet these requirements, the production equipment and automatic production line of control system must have high reliability and fle

4、xibility. Programmable controller is catering to this request, it appears on the microprocessor-based general industrial control device. This paper introduces fx2n series programmable controller for the control of the manipulator, including PLC and I/O assignment graph and the wiring diagram, using limit switches and PLC program, in cooperation according to its process flow driven manipulators finish work. Because with the flexibility, PLC modularization and easy to expand, and its reliability
