PLC在电镀生产线上的应用VIP免费

PLC在电镀中的应用摘要电镀生产线自动化的程度在德国、意大利、美国等国家的发展水平已经比较高，而在我国尚处于发展阶段。本课题以行业现状为出发点，结合其他行业自动化控制技术、可编程控制器（PLC）等多项专门技术开发的自动生产系统。本文首先分析和制定了该生产的整体设计思想和方案，确保了该生产系统具备真正的自动化生产能力且结构简单。在该生产系统中，采用了高可靠性，高稳定行，编程简单，易于使用而且广泛应用于现代工业企业生产线过程中的控制器PLC。分成次的从功能图，梯形图入手，最后在起-保-停程序输入模拟量，进行模拟现场，从而得到比较清晰的结果，具有非常强的实用性。关键词：电镀自动化；可编程控制器（PLC）；吊钩；梯形图AbstractDegreeofautomationofelectroplatingproductionlineinGermany,Italy,theUnitedStatesandothercountrieshavearelativelyhighlevelofdevelopment,whileinChinaisstillindevelopmentstage.Thetopicstotheindustrystatusquoasastartingpoint,incombinationwithotherindustryautomationandcontroltechnology,programmablelogiccontroller(PLC)andmanyotherspecializedtechnicaldevelopmentofautomatedproductionsystems.Inthispaper,analysisanddevelopmentoftheoveralldesignoftheproductionofideasandprogramstoensurethattheautomationofproductionsystemswitharealproductiveandsimplestructure.Intheproductionsystem,usingahigh-reliability,highstabilityline,programmingsimpleandeasytouseandarewidelyusedinmodernindustrialproductionlineprocesscontrollerinthePLC.Fromthefunctionisdividedintosub-diagrams,Ladderstart,intheendfrom-Paul-stopprograminputanalog,simulatedon-sitetoobtainmoreclearresult,withverystrongpracticability.Keywords:electroplatingautomation;ProgrammableLogicController(PLC);hook;Ladder1目录2摘要.................................................................................1第一章前言..............................................................................31.1、PLC的发展情况及前景.............................................................31.2、可编程序控制的应用...............................................................41.3、可编程控制器的性能指标...........................................................51.4、电镀生产线的系统简介............................................................61.5、该系统设计主要内容...............................................................61.6、设计原理介绍.....................................................................7第二章设计工艺要求......................................................................72.1、工艺制作背景要求.................................................................72.2、工艺流程图及控制流程.............................................................82.3、工作状态流程图及I/O点数统计....................................................102.4、PLC选型及I/O点的分配..........................................................11第三章程序设计及运行...................................................................133.1、梯形图程序......................................................................133.2、STL梯形图及指令表..............................................................173.3、起保停梯形图及指令表............................................................203.4、故障输出程序....................................................................223.5、调试运行........................................................................24设计小结...............................................................................25谢辞...........
