图书馆AGV小车起升机构设计(含CAD图,CAXA图)(课题申报表,任务书,开题报告,中期检查表,论文说明书14300字,CAD图纸12张,CAXA图纸12张)
摘 要
本次设计主要是针对图书馆AGV小车起升机构进行设计。其中包括齿形带、竖直上下带轮、电机座、机架等总成的结构设计及个总成中主要零件的结构设计，以及驱动电机、皮带、带轮、轴承等主要零部件的选型和有关零件的强度计算。
在计算部分，首先，进行有关参数的选取确定，包括带速、载重、安全系数的确定，带的单位质量的计算，输送带张力的计算以及驱动电机的功率计算。然后进行各个主要零部件的选型和设计计算。
在设计过程中，参考了多部文献以及工程实践人员的经验心得，对各部分机构进行了认真比对，选取通用结构，以便于输送机的修理与维护。波状挡边带式输送机的应用已经日趋成熟，通过对各个部件的优化及选择更合理的结构，将更大的提高其应用效率。
本文介绍了AGV在国内外的发展现状和应用情况，在此基础上，结合毕业设计的课题要求，设计了图书馆AGV小车起升机构。其研究内容主要包括以下几个方面:
论述了图书馆AGV小车起升机构的组成及原理，结合课题要求，选择电动机起升机构作为该机构的运作方式。
介绍了图书馆AGV小车起升机构机械结构的设计，并根据小车起升机构的驱动方式和工作要求，对皮带、电机、带轮、轴等进行了设计和选型。
根据图书馆AGV小车起升机构的结构和工艺要求，确定了总体框架结构。硬件方面，选择合适的皮带、电机、带轮，对轴进行了设计。
在总结全文的基础上，对AGV小车的设计和研究提出了展望。

Abstract
With the growing of Factory Automation, Computer Integrated Manufacture System and extensive application of Flexible Manufacture System、Automatic Warehouse, the application field and technical level of AGV which contact and adjust the discrete logistics system, make the mission continuous, has greatly enlarged and improved.
AGV is the unmanned driver automatic guided vehicle which has its untouched guided equipment, its control center is the microcontroller and storage battery is driving power, its basic function of automatic action is guided driving, recognizing the address to stop precisely and remove the load. As the valid measure of contemporary logistics processing automation and the key equipment of flexible manufacture system, the AGV has already got more and more extensive application, so that the research on AGV has very important theory meaning and realistic meaning.
The main work in this dissertation was arranged as follows:
The constitution of AGV system, the path guided means and their principles were discussed. According to the requests of the topic, infrared rays guided method was used in the AGV system.
According to the control and the craftwork requests of the AGVS, the total frame structure of control system was designed. About hardware, the right sensor, MCU and motor controller had been chosen, the sensing circuits and MCU controlling hard circuits was designed, about software, to achieve many system functions, and to realize serial communication between the MCU and motor controller, blocking programming method was employed.
On the base of summarizing the dissertation, the development prospect of AGV research was put forward.
