摘要

本文主要對家用型自動牙膏機主體進行詳細的設(shè)計、計算、校核、選型。分
析了家用型自動牙膏機要求實現(xiàn)的功能要求，了解了同類型家用型機構(gòu)的工作原
理，基本結(jié)構(gòu)，系統(tǒng)組成及功能；研究了家用型自動牙膏機的系統(tǒng)構(gòu)成及功能，
各元器件的選型方法，以及系統(tǒng)的實現(xiàn)方式等。
自動牙膏機是一個簡單的機電一體化產(chǎn)品，融合了紅外技術(shù)，單片機，繼電
器，電機等相關(guān)技術(shù)。其主要技術(shù)路線是通過紅外感應(yīng)控制，觸發(fā)電機工作，通
過控制電機的行程來控制牙膏的擠出量。
設(shè)計主要包括了家用型自動牙膏機的結(jié)構(gòu)，裝配，選材，控制系統(tǒng)設(shè)計，電
機選擇，以及標準件的選擇。本文對設(shè)計中，家用型自動牙膏機的結(jié)構(gòu)圖，裝配
圖，零件圖，以及控制系統(tǒng)的電路圖，單片機程序，都有詳細的說明。

Abstract

In this paper,its mainly about the detailed design, calculation, checking&selection
of the Automatic toothpaste machine.It analyzes the Functional requirements of the
Automatic toothpaste mf small household appliances.It researched the System
Structure and Function of the Automatic toothpaste machine,the way to select

comachine.Understanding the working principle,Basic
structure,System

components&Function of the same type oponents&the Realization of the systerm.
Automatic toothpaste machine is a simple product of mechatronics,it includes
infrared technology,SCM technology,relay,motor technology and so on.Through the
control of infrared sensors,trigger the motor’s working,then control the etrusion
volume of the toothpaste through the trip of the motor.And this is the main technical
route of the Domestic-automatic toothpaste machine.
The design mainly about structure desgin, assembly, material selection,control
system design,selection of motor&the standard parts.In this paper,there have detailed
explanations about the structure, assembly, parts map, and the control system circuit
diagram& SCM procedures of the Automatic toothpaste machine.
Keywords：infrared sensors；Delay Control；Virtual assembly；SCM89C2051
