自动摆料机毕业论文

我给你好了。论文是一项“系统工程”，在正式动笔之前，要对文章进行通盘思考，检查一下各项准备工作是否已完全就绪。首先，要明确主题。主题是文章的统帅，动笔之前必须想得到十分清楚。清人刘熙载说：“凡作一篇文，其用意俱可以一言蔽之。扩之则为千万言，约之则为一言，所谓主脑者是也。”(《艺概》)作者要想一想，自己文章的主题能否用一句话来概括。主题不明，是绝对不能动手写文的。其次，是理清思路。思路是人订]思想前进的脉络、轨道，是结构的内在依据。动笔之前，对怎样提出问题，怎样分析问题，怎样解决问题，以及使用哪些材料等，都要想清楚。第三，立定格局。所谓“格局”，就是全文的间架、大纲、轮廓。在动笔之前先把它想好“立定”，如全文分几部分，各有哪些层次，先说什么，后说什么，哪里该详，哪里该略，从头至尾都应有个大致的设想。第四，把需要的材料准备好，将各种事实、数据、引文等找来放在手头，以免到用时再去寻找，打断思路。第五，安排好写作时间、地点。写作要有相对集中的时间，比较安静的环境，才能集中精力专心致志地完成毕业论文写作任务。

我帮你找了些资料,不知道是不是你要的。自动上料机构 auto loader system of the automatic loader system for plastic package of integrated circuitYA0 Xing-tian, QIU Zi-xue, ZH0U Yi-dan, ZHU Wei-nan, LIU Jian-feng （ of Mechanical Engineering, Nantong University, Nantong 226007, China; 2. Nantong Fujitsu Microelectronics Co., Ltd, Nantong 226001, China）Abstract:In order to realize automation for plastic package of integrated circuit, an automatic loader system was designed. Lead-frame transport, lead-frame placement and lead-frame preheating were controlled by the synchronization control technique of multi-movement. Fast precise positioning of the manipulator was performed by the large-pitch ball screws and the high-resolution servo systems. The flexible runner structure was designed to fit different dimension lead-frames. The special industrial control software was also developed based on windows 2000. The system can be applied to the plastic package for DIP, QFP, SOP and TO series integrated circuits. The production efficiency and the product quality would be improved greatlyKey words:integrated circuit; plastic package; load; automation摘要本文简要地介绍了机器手的概念、发展状况及其组成，气动技术的应用，PLC控制的特点及国内外的发展状况。本文对气门自动上料装置进行了总体方案设计，针对一台可用于磨削气门的数控机床，设计其自动上料系统机械手。对其进行了详细的机械设计、传动系统设计以及控制系统设计。设计部分包括：上料机构设计；摆料机构设计；机构运动学分析；误差分析；动力计算；控制系统；驱动系统；执行系统等。确定了上料机械手的上料机构、摆料机构等的具体尺寸，并对传感器和控制部分进行了选择，整个动作的完成是通过气缸驱动的，并利用PLC进行了编程控制。关键词 机械手， 气动技术，PLC控制程序AbstractThis article introduced machinist's concept, the development condition and the composition briefly, air operated technical application, PLC control characteristic and domestic and foreign development condition. This article has carried on the overall concept design to the tire valve automatic high-quality goods installment, in view of one available in grinding tire valve numerical control engine bed, designs its automatic high-quality goods system manipulator. Has carried on the detailed machine design, the transmission system design as well as the control system design to it. The design part includes: High-quality goods organization design; Suspends the material organization design; Organization kinematic analysis; Error analysis; Power computation; Control system; Actuation system; Execution system and so on. Had determined high-quality goods manipulator's high-quality goods organization, pendulum material organization and so on concrete size, and has carried on the choice to the sensor and the control section, entire movement completion is actuates through the air cylinder, and has carried on the programming control using PLC.
