1.电气自动化的论文 PLC的
基于PLC控制系统的材料的机械臂 摘要 本设计所用机械部件有滚珠丝杠、滑轨、气控机械抓手等。
电气方面有可编程控制器(PLC)、编程器、步进电机、步进电机驱动器、直流电机、光电传感器、开关电源、电磁阀、旋转码盘、操作台等部件。可编程控制器发出两路脉冲到步进电机驱动器,分别驱动横轴、竖轴的步进电机运转;直流电机拖动底座和手爪的旋转;接近开关、微动开关、旋转码盘将位置信号反馈给主机,由主机发出指令来实现对手臂的伸缩、上下、转动位置的控制;主机发信号到气动电磁阀,以控制手爪的张合来抓放物体。
本设计可根据工件的变化及运动流程的要求随时更改相关参数,具有很大的灵活性和可操作性。 关键词:可编程控制器;机械手;步进电机;步进驱动器;脉冲;传感器;直流电机 Materials based on PLC control system for manipulator Abstract There are such mechanical components as ball footbridge, slides, an air control mechanical hand and so on in the design. A programmable controller, a programming device, stepping motors, stepping motors drives, direct current motors, sensor, switch power supply, an electromagnetism valve and control desk are used in electrical connection. The programmable controller output two lines pulses to stepping motors drives to drive the two stepping motors drives on beam and vertical axis; direct current motors drive the rotation of the base and the hand; sensors send signals of location to the mainframe, and the mainframe sends directive to control the extension and contraction, up and down, moves location; the mainframe send signals to control the opening and closing of the hand to carry objects. Related parameters can be changed according to request of the changes of the objects and movement flow at any time change the relevant parameters in the design, so it has great flexibility and operability.

It is the programmable controller of FX2N series of Mitsubishi Company that was originally designed and adopted, the programming respect of the software adopts and walks into the order and state programming law, pass the operation control of the machine of programming realization of PLC correctly. This design includes brick go back origin , skip form step and full-automatic working way according to task demand to design originally, involve crafts too. Design and peripheral wiring of PLC of control panel make panel control PLC control to the hardware and then, it is integral to control the course entirely.Keyword: PLC electric control system punching machine目 录摘 要…………………………………………………………………………………………ⅠAbstract ………………………………………………………………………………………Ⅱ第1章 概述 ……………………………………………………………………………1 1.1压砖机的现状与发展前景…………………………………………………………1 1.2主要构造和技术参数………………………………………………………………2 1.2.1压砖机的结构构造……………………………………………………………2 1.2.2主要技术参数…………………………………………………………………2 1.3主要控制内容………………………………………………………………………3 1.3.1主要控制内容…………………………………………………………………3 1.3.2液压控制系统…………………………………………………………………3 1.3.3电气控制系统…………………………………………………………………4 1.3.4PLC控制原理…………………………………………………………………5 1.4 设计要求和内容……………………………………………………………………6第2章 控制原理……………………………………………………………………………7 2.1电气控制原理………………………………………………………………………7 2.2各电机的运行………………………………………………………………………8 2.2.1主泵电机的运行………………………………………………………………8 2.2.2循环电机的运行………………………………………………………………9 2.2.3料箱布料电机的运行…………………………………………………………9第3章 硬件的设计…………………………………………………………………………10 3.1元件的选型………………………………………………………………………10 3.1.1电动机的选型………………………………………………………………10 3.1.2断路器的选型………………………………………………………………12 3.1.3电流、电压表的选型………………………………………………………14 3.1.4交流接触器的选型…………………………………………………………14 3.1.5熔断器的选型………………………………………………………………15 3.1.6中间继电器的选型…………………………………………………………17 3.1.7按钮的选型…………………………………………………………………18 3.1.8信号灯的选型………………………………………………………………19 3.1.9电流互感器的选型…………………………………………………………20 3.1.10电阻器的选型 ……………………………………………………………21 3.1.11可编程控制器的选型 ……………………………………………………22第4章 软件的设计………………………………………………………………………28 4.1压砖机的工作流程 ……………………………………………………………28 4.2软件的总体结构 ………………………………………………………………28 4.3各工作方式的子程序 …………………………………………………。
