摘 要
本次設(shè)計(jì)主要是針對(duì)圖書館AGV小車起升機(jī)構(gòu)進(jìn)行設(shè)計(jì)。其中包括齒形帶、豎直上下帶輪、電機(jī)座、機(jī)架等總成的結(jié)構(gòu)設(shè)計(jì)及個(gè)總成中主要零件的結(jié)構(gòu)設(shè)計(jì)，以及驅(qū)動(dòng)電機(jī)、皮帶、帶輪、軸承等主要零部件的選型和有關(guān)零件的強(qiáng)度計(jì)算。
在計(jì)算部分，首先，進(jìn)行有關(guān)參數(shù)的選取確定，包括帶速、載重、安全系數(shù)的確定，帶的單位質(zhì)量的計(jì)算，輸送帶張力的計(jì)算以及驅(qū)動(dòng)電機(jī)的功率計(jì)算。然后進(jìn)行各個(gè)主要零部件的選型和設(shè)計(jì)計(jì)算。
在設(shè)計(jì)過程中，參考了多部文獻(xiàn)以及工程實(shí)踐人員的經(jīng)驗(yàn)心得，對(duì)各部分機(jī)構(gòu)進(jìn)行了認(rèn)真比對(duì)，選取通用結(jié)構(gòu)，以便于輸送機(jī)的修理與維護(hù)。波狀擋邊帶式輸送機(jī)的應(yīng)用已經(jīng)日趨成熟，通過對(duì)各個(gè)部件的優(yōu)化及選擇更合理的結(jié)構(gòu)，將更大的提高其應(yīng)用效率。
本文介紹了AGV在國內(nèi)外的發(fā)展現(xiàn)狀和應(yīng)用情況，在此基礎(chǔ)上，結(jié)合畢業(yè)設(shè)計(jì)的課題要求，設(shè)計(jì)了圖書館AGV小車起升機(jī)構(gòu)。其研究?jī)?nèi)容主要包括以下幾個(gè)方面:
論述了圖書館AGV小車起升機(jī)構(gòu)的組成及原理，結(jié)合課題要求，選擇電動(dòng)機(jī)起升機(jī)構(gòu)作為該機(jī)構(gòu)的運(yùn)作方式。
介紹了圖書館AGV小車起升機(jī)構(gòu)機(jī)械結(jié)構(gòu)的設(shè)計(jì)，并根據(jù)小車起升機(jī)構(gòu)的驅(qū)動(dòng)方式和工作要求，對(duì)皮帶、電機(jī)、帶輪、軸等進(jìn)行了設(shè)計(jì)和選型。
根據(jù)圖書館AGV小車起升機(jī)構(gòu)的結(jié)構(gòu)和工藝要求，確定了總體框架結(jié)構(gòu)。硬件方面，選擇合適的皮帶、電機(jī)、帶輪，對(duì)軸進(jìn)行了設(shè)計(jì)。
在總結(jié)全文的基礎(chǔ)上，對(duì)AGV小車的設(shè)計(jì)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.
