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：0604103125 专 业：机械设计制造及其自动化 班 级：机械06-1班 指导教师： PCB(印刷电路板)自动剪脚机 摘 要关键词： Printed circuit board (PCB) automatically cut the feet Abstract Automatic cutting machine is a kind of feet of printed circuit board will cut off the foot long,in the production lines and occupies an important position.Its working principle for printed circuit boards on the transmission device,spread below tool,the tool will have long pin to cut off.In the production process of printed circuit board is indispensable. This machine is suitable for cutting feet of small scale of production machines, automatic feet, but in small scale of production in general use manual mode of feet with foot two small cut machine, so it can solve this problem. My topic is designedThe printed circuit board (PCB) automatically cut the feet of the machine design. By a single motor drive, with big load, smooth operation and reliable, simple structure, easy maintenance, management, maintenance convenience features such as long cycle. In this design, I finished the job: The selection of design scheme and determination, relevant design calculation, complete specifications, drawings, graduation design etc. Keywords: Printed circuit boards；Cutting machine feet；Transportation device 目录 摘 要····································································································Ⅰ Abstract·····································································································Ⅱ 目 录······································································································ 1 第一章 绪 论····························································································3 1.1本课题研究的目的意义········································································3 1.2开题意义·························································································3 1.2.1调查·······························································
