1、 I 图书分类号： 密 级： 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

2、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。 关键词关键词 自动装箱；单片机；光电检测；输送装置 II 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. Th

3、e 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 pac
