摘要
设计了一种基于AT89C51单片机中断的封帽机人手保护系统。通过在下电极放置微动开关触发中断,根据中断实时响应和高低中断嵌套的特性,控制电磁阀开合,从而对操作者的双手进行保护。详细介绍了该方法的原理、电气连接和机械设计部分,并给出主要程序流程图和关键程序代码。为封帽机的智能化和安全性提供了解决方案。同时,该系统采用模块化的设计思想,具有良好的可移植性,可用于类似的汽缸驱动的点焊机。
A protection system of cap-sealing machine base on AT89C51 MCU interruption was designed.Interruption is activated by the micro-switch under the bottom electrode.With the real-time response and the nesting characteristics of interruption,Solenoid valve was controlled to open and close,so that the hands of the operators were protected.This paper describes the principles,electrical connection diagram and the mechanical design section of this method,and gives out the main program flow chart and key code.For the sealing cap machine to provide a solution.Provided a solution for the intelligization and security of the cap-sealing machine.At the same time,the system uses a modular design concept,which has a good portability,which can be used for the similar cylinder-driven spot welders.
