……本科毕业设计说明书（论文）I摘要随着电子产业的发展，电子产品在人们的日常生活中起到越来越重要的主要。人们对电子产品的薄、轻、小型化的需求，使得电子产品朝着薄、轻、小型化不断发展。电子元件是电子产品的重要组成部分，其性能直接影响着电子产品的质量，因此对电子元件的检测就显得尤为重要。传统的目检测是用放大镜等直接人工识别，耗费的时间和劳力多而且精度低，为了减轻以往作业量，且让出货作业更准确，并降低检测成本，所以设计这样一套电子元件目检测设备。本设备是通过放料机构将电子原件放在料带中，然后通过传动机构输送到摄像头下，并通过显示屏放大，便于人工识别，以达到将不同型号的电子元件分拣开的目的，同时还可以控制电子元件放料和收料的速度，实现电子元件在料带上的间歇性运动。该设备可以改变传统目检测的不足，大大提高工人工作效率，减轻劳动强度并提高工作的准确度。课题基于机械设计理论，确定了电子元件目检设备的方案，根据设备运动形式和运动参数的要求确定原动机的类型和参数，设计出各组成机构的零、部件的材料、外形及基本尺寸，绘制相应的装配图以及主要零部件图。关键词：电子元件；目检设备；料带。……本科毕业设计说明书（论文）IIAbstractAstheelectronicsindustry,electronicproductsplayinpeople'sdailylivesmoreandmoreimportantmajor.Electronicproducts,peoplethin,light,smalldemandmakeselectronicproductstowardthethin,light,smallgrowing.Electroniccomponentsisanimportantpartofelectronicproducts,itsperformancedirectlyaffectsthequalityofelectronicproducts,sothedetectionofelectroniccomponentsisparticularlyimportant.Thetraditionalobjectivetestareidentifiedwithamagnifyingglassandotherdirectlabor,timeandlaborconsumingmoreandlowprecision,inordertoreducetheamountofpastwork,andmakemoreaccurateshippingoperations,andreducetestingcosts,designsuchatestheadofelectroniccomponentsequipment.Thedeviceisexpectedtotakeplaceelectroniccomponents,throughtransmissiontransportedtothenextcameraandzoomthroughthescreen,easytomanualidentification,thesortingofdifferenttypesofelectroniccomponentsopenatthesametimecontrolthedischargeofelectroniccomponentsandmaterialsreceivedspeed.Thedevicecangreatlyimprovetheefficiencyofworkersandreducelaborintensityandimproveaccuracy.Subject-basedmechanicaldesigntheory,determinethepurposeofelectroniccomponenttestingmachine,theprogram,accordingtotheformandmotionparametersforMotion'srequirementstodeterminethetypeandparametersoftheoriginalDongjitodesignthecompositionofbodypartsandcomponentsofthebasicshapeandsize,drawthecorrespondingassemblydrawingandthemainpartsdiagram.Keywords：surfacemounteddevices;ManualVisionSystem；carriertape.……本科毕业设计说明书（论文）III目录摘要................................................................................................................IAbstract................................................................................................................II1绪论...........................................................................................................11.1本课题的研究背景....................................................................................................11.2本课题的研究意义....................................................................................................11.3国内外发展现状........................................................................................................12总体方案的确定...............................................................................................33原动机的选定...................................................................................................43.1原动机的分类............................................................................................................43.2步进电动机的优点....................................................................................................43.3步进电动机的选型.....................................................................................................54减速器的确定...................................................................................................64.1减速器的分类.............................................................................................................64.2减速器齿轮的计算....................................................................................................64.3轴的设计...................................................................................................................114.4润滑与密封及箱体尺寸..........................................................................................135带传动的设计..................................................................................................145.1带传动.......................................................................................................................145.2带传动的计算...........................................................................................................145.3放料机构和导料带轮的设计...................................................................................175.4轴的设计..................................................................................................................196控制部分的设计..............................................................................................226.1PLC的分类...............................................................................................................226.2S7-200的选择..........................................................................................................226.3PLC的自动化控制...................................................................................................237机架和导轨的设计..........................................................................................247.1料带轨道组件........................................................................................................
