PLC流水线毕业论文

河南机电高等专科学校毕业设计（论文）自动化流水线控制系统之机械手系部:自动控制专业:电气自动化班级:112班姓名:张璐燕学号:111415232指导老师:宋守云二零一四年四月编号2352482摘要I摘要现代化的自动生产设备，即自动化流水线控制系统的最大特点是它的综合性和系统性。机械手是自动化流水线控制系统中传统的任务执行机构，是机器人的关键部件之一。本文中机械手涉及到8个动作过程，我们将通过各种编程软件操作简单方便，而且可通过和计算机的通信实时的对工作程序进行模拟调试和修改，械手是自动化流水线控制系统的一部分，是机电一体化的结合，为了使工业机械手的操作自动化程度提高，机械手可人机界面控制，通过触摸屏的来对机械手的运功过程进行操作，人机界面能更加直观方便的对机械手的运动过程进行控制和实时监控，使用PLC编程控制器和人机界面一起对工业机械手的运动过程进行控制。本文介绍的机械手是主要由PLC控制，通过交流电机的正反转来控制机械手手爪的张合，从而实现机械手精确运动的功能。本课题机械手可在空间抓、放、搬运物体，动作灵活多样，适用于可变换生产品种的中、小批量自动化流水线生产，广泛应用于柔性自动线，动作灵活多样。机械手一般由耐高温，抗腐蚀的材料制成，以适应现场恶劣的环境，可代替人工在高温和危险的作业区进行作业，并可根据工件的变化及运动流程的要求，随时更改相关参数。大大降低了工人的劳动强度，提高了工作效率。关键词：机械手；PLC；人机界面；触摸屏；自动化流水线控制系统AbstractIIABSTRACTModernautomaticproductionequipment,automatedassemblylinecontrolsystemisthebiggestcharacteristicofitscomprehensiveandsystemic.Manipulatorisautomatedassemblylinecontrolsysteminthetraditionaltaskexecutingagency,isoneofthekeycomponentsoftherobot.Thisarticlemanipulatorinvolvingeightactionprocess,wewillthroughavarietyofprogrammingsoftware,simpleandconvenientoperation,andcanthroughthecommunicationandcomputerreal-timesimulateddebuggingandmodificationtotheworkprogram,bothhandsispartoftheautomaticproductionlinecontrolsystem,isthecombinationofmechanicalandelectricalintegration,inordertomaketheoperationoftheindustrialmanipulatortoimprovedegreeofautomation,manipulatorcanman-machineinterfacecontrol,throughthetouchscreentoworkprogressofthemanipulator,man-machineinterfacecanbemoreintuitiveandconvenientfortheprocessofmovementofmanipulatorcontrolandreal-timemonitoring,usingPLCprogrammingcontrollerwithman-machineinterfacetocontrolthemotionprocessofindustrialmanipulator.ManipulatorisintroducedinthispaperismainlycontrolledbyPLC,throughtheacmotorisFanZhuanLaicontrolmanipulatorgripperzhang,soastorealizethefunctionofmanipulatoraccuratelymovement.Thistopicmanipulatorcangraspinthespace,place,movingobjects,flexible,suitableforcantransformtheproductionofvarietiesofmediumandsmallbatchautomationproductionline,widelyusedinflexibleautomaticline,flexibleandvaried.Manipulatorgenerallybythehightemperatureresistant,corrosionresistantmaterials,toadapttotheharshenvironment,canreplaceartificialtooperateathightemperaturesanddangerousareas,andcanaccordingtotherequirementsofthechangeoftheworkpieceandthemovementprocessatanytimechangetherelevantparameters.Greatlyreducesthelaborintensityofworkers,improvetheworkingefficiency.Keywords:Manipulator;PLC;man-machineinterface;touchscreen;automatedassemblylinecontrolsystem目录ii目录第1章绪论..................................................................................................1第2章设计思路或方案的选择..................................................................32.1设计内容........................................................32.2系统的整体设计...........................................................32.3PLC的选择......................................................4第3章硬件电路设计..................................................................................63.1电气原理图......................................................63.1.1输入接口电路.........................................................63.1.2输出接口电路.........................................................73.1.3PLC的组成...........................................................73.2电I/O分配表.............................................................83.2.1表的内容............................................................83.2.2输出输入点分配及I/O分配接线.........................................9第4章软件设计........................................................................................114.1工作流程图.....................................................124.2程序梯形图见附录...............................................12第5章触摸屏............................................................................................135.1TPC7062KS人机界面............................................135.2初步认识人机界面...............................................135.3初步认识组态软件...............................................135.4了解触摸屏的接口及组态.........................................155.5TPC7062KS人机界面的硬件连接..................................16第6章自动流水线控制系统监控画面的制作........................................18目录ii6.1规划联机所需要的辅助继电器清单.................................186.2建立仿真画面...................................................196.2.1创建新的工程................................................196.2.2建立新的画面................................................196.2.3定义变量及命令语言..........................................216.3了解触摸屏的接口及组态.........................................246.4程序调试.......................................................256.4.1使用设备....................................................256.4.2调试过程....................................................25第7章结论与展望....................................................................................267.1结论...........................................................267.2不足之处及未来展望.............................................26参考文献......................................................................................................27致谢.....................................
