基于PLC的机械手设计.doc

浙江万里学院本科毕业设计（论文）（2013届）论文题目基于ＰＬＣ的机械手控制系统设计（英文)ThedesignofmachinehandcontrolsystembasedonPLC所在学院电子信息学院专业班级电气工程及其自动化学生姓名xxx学号2009017141指导老师xxx完成日期xxxx年x月x日基于PLC的机械手控制系统设计xxx（浙江万里学院电子信息学院电气工程及其自动化094班）xxx年x月摘要随着自动化技术的不断发展，实现了绝大部分的机械设备的自动控制，工业中的机械手就是其中之一。由于机械手的出现,它代替了一些在恶劣环境下、工作强度大，甚至有生命危险的工人工作；又因其能按照一定的程序、时间和位置来完成货物产品的传送和装卸大大节约了劳动力，在现代工业中的使用率越来越频繁。而机械手的自动化实现有很多方式，PLC控制就是其中的一种。PLC是一种以微处理器为核心的工控装置它采用可以编程的存储器，用来在其内部存储执行逻辑、顺序、计时、计数和算数运算等操作的指令，并能通过数字、模拟的输入输出控制各类设备的运行。本设计的机械手所涉及到的运动过程，将通过对PLC软件编程驱动机械手上的步进电机运动，经过不断地编程调试使其能完成上升、下降，左右移动，加紧和放松物件的运动。关键词：机械手；PLC；步进电机AbstractWiththecontinuousdevelopmentofautomationtechnology,realizestheautomaticcontrolofmostofmachineryandequipment,machineryindustryistheonehandappeared,itreplacessomeworkinharshenvironment,highintensity,andevenlife-threateningworkers;andbecausethecaninaccordancewithcertainprocedures,timeandlocationtocompletethetransferandloadingandunloadingofgoodsproductgreatlysaveslaborinthemodernindustryintheuseofmoreandmorefrequently.Automaticmechanicalhandhasmanyways,aPLCcontrolisoneofthe.PLCisakindofindustrialcontroldevicewithmicroprocessorasthecoreofthememorycanbeprogrammed,usedtoimplementlogic,sequence,timing,countingandarithmeticoperationinitsinternalstorageinstructions,andthroughdigital,analoginputandoutputofthecontrolofvarioustypesofequipmentoperation.Thedesignoftherobotmotionprocessinvolved,willbethroughthePLCsoftwareprogrammingtodrivethemanipulatoronthesteppermotor,throughcontinuousprogramminganddebugging,sothatitcancompletetherise,decline,andmovearound,steppingupandrelaxtheobjectmotion.KeyWords:Machinehand;PLC;Steppermotor目录1引言·····························································11.1课题研究的目的与意义··········································11.1.1机械手的概况················································11.1.2机械手在国内外的发展状况····································22控制方案2.2可编程逻辑控制器（PLC）的概述·································32.2.1PLC的结构··················································32.2.2PLC的特点······································
