摘要
本次畢業(yè)設(shè)計的題目是設(shè)計一種基于單片機(jī)控制的玻璃橫切機(jī)。主要設(shè)計內(nèi)容為：設(shè)計玻璃橫切機(jī)的機(jī)械結(jié)構(gòu)及人機(jī)界面系統(tǒng)。機(jī)械結(jié)構(gòu)部分的設(shè)計確定為步進(jìn)電動機(jī)帶動的同步帶傳動系統(tǒng)?？刂葡到y(tǒng)采用AT89C51為CPU。由矩陣鍵盤和RT12864M漢字圖形點(diǎn)陣液晶顯示模塊組成人機(jī)界面系統(tǒng)。
首先，分析了玻璃橫切機(jī)的市場前景及其在玻璃生產(chǎn)中的重要作用。然后，確定機(jī)械結(jié)構(gòu)。根據(jù)現(xiàn)有的玻璃橫切機(jī)的結(jié)構(gòu)將其分類，并歸納出每一類玻璃橫切機(jī)的機(jī)械機(jī)構(gòu)特征、運(yùn)行特征、切割原理等。本設(shè)計最終選用了其中的斜置、速度控制式的機(jī)械結(jié)構(gòu)。基于這種機(jī)械結(jié)構(gòu)，對步進(jìn)電動機(jī)、同步帶進(jìn)行了選型和計算。繪制了機(jī)械結(jié)構(gòu)裝配圖及部分零件圖。
對于玻璃橫切機(jī)的人機(jī)界面系統(tǒng)，本設(shè)計主要大致完成其程序的編寫。即液晶顯示四組控制參數(shù)，并可以通過鍵盤修改這些參數(shù)。本文中包括了各級程序流程圖及其對應(yīng)的說明。大致包括LCD驅(qū)動、鍵盤監(jiān)控、液晶顯示三個程序塊。詳見正文。

Abstract
This graduation project's topic is the design of one kind of the auto glass-cutter which controls based on the Microcontroller. The main content of the design is: the machine mechanism and man-machine contact surface system of the glass-cutter’s design .The mechanism part's design I determined it as that Pulse motor gives the power and the Transmission system transfer the power to the Ambulacrum.The control system uses AT89C51 as CPU. Forms the man-machine contact surface department of the matrix keyboard and the RT12864M Chinese character graph lattice liquid crystal display module.
First, has analyzed the glass-cutter’s market prospect and its influential role in the glass production. Then, determination of the machine mechanism. According to the existing glass-cutter’s structure I staple then to same types, and then concluded the mechanism character, sport character, cutting principle of each of the types. And so on.
This design finally has selected the tilts, speed control-like mechanism. Based on this kind of mechanism, I did the choice of the Pulse motor, ambulacrum’s and the count, checkout of them. I had drawn up the drawing of mechanism assembly and some part drawings.
Regarding the glass-cutter’s man-machine contact surface system, this design mainly completes its program’s compilation. Namely the liquid crystal display shows the four groups of controlled variables, and may revise these parameters through the keyboard. This article has included all levels of program flow diagram and the corresponding explanation. Includes the LCD actuation, the keyboard monitoring, and the liquid crystal display three blocks approximately. For details sees the main text.
