1、内蒙古科技大学本科生毕业设计说明书（毕业论文）题目：PCB(印刷电路板)自动剪脚机的设计学生姓名：学号：专业：机械设计制造及其自动化班级：机械06-1班指导教师：37内蒙古科技大学毕业设计说明书（毕业论文）PCB(印刷电路板)自动剪脚机摘要自动剪脚机是一种将印刷电路板的过长的引脚剪掉的设备，在生产流线中越来越占据重要的位置。其工作原理为印刷电路板放在传动装置上输送，传到刀具下方，刀具将其过长的引脚剪掉。它在整个生产印刷电路板的工艺过程中是必不可少的。这种剪脚机是适用于中小型生产规模的自动剪脚机，而在中小规模的生产线中一般使用的剪脚方式有手动与使用
2、小型剪脚机两种，所以这样就能够解决这个问题。我的设计题目是“PCB（印刷电路板）自动剪脚机的设计”，采用单电动机传动方式，具有承载量大、运转平稳可靠、结构简单、容易维修、管理方便、检修周期长等特点。在这次设计中，我完成了以下工作：设计方案的选择与确定，相关设计计算，完成毕业设计说明书，相关图纸等。关键词：印刷电路板；剪脚机；运输装置37内蒙古科技大学毕业设计说明书（毕业论文）Printedcircuitboard(PCB)automaticallycutthefeetAbstractAutomaticcuttingmachineisakindof
