摘要
本文主要设计了一种以AT89S51单片机为核心的产品自动装箱控制系统，能够对自动化生产流水线上的产品进行精确的计数和装箱。主体部分采用两条传送带，一条是包装箱传送带，另一条是产品传送带。对产品计数采用光电传感器，并与单片机AT89S51接口，再通过单片机对交流电机的控制，实现产品的自动装箱。本设计的内容分为两部分：物品传动皮带机构设计，单片机控制电路设计。其中物品传动皮带机构与带式输送机的结构相似，该带式输送装置由输送带，托辊，驱动装置，拉紧装置等组成。而单片机控制部分主要分析了单片机与光电传感器协同工作和数据处理等方面。通过单片机对电动机等各机械部分的控制来实现系统要求，从而达到自动化生产的水平。

Abstract

This paper has mainly designed an automatic packing control system for products. The core is monolithic computer of AT89S51. It carries on the precise counting and packing for the products on the automation process line. The main part uses two conveyor belts. One is package conveyor belt, and the other is product conveyor belt. The photoelectric sensor is used for the product counting and connects with the monolithic computer of AT89S51. The monolithic computer controls the motor. At last it realizes the automatic packing. This design divides into two parts. One is the design of goods transmission belt, and the other is the design of circuit control of monolithic computer. The goods transmission belt is similar to the belt conveyor's structure, this conveyor belt is installed by the conveyor belt, the supporting roller, the drive, the tightening device and so on. The joint operation between monolithic computer and photoelectric sensor has been analyzed in the section of circuit control. The data processing also has been analyzed. We can achieve the requirements of system through the control on mechanical part, the motor and so on, thus reach the level of producing in automation.
