基于单片机的PCB雕刻机系统设计

摘要

This paper designs a system of PCB engraving machine using SCM,and focuses on design in detail mechanical structure and the system scheme of the engraving machine.Besides,it makes out software which can transform the file of PCB drawing software output to program for SCM and exchange data between PC and SCM,chooses the right step motor,and designs driven circuit of step motor.%设计了一套利用单片机实现的PCB雕刻机系统. 重点设计了雕刻机的机械结构和整个系统的方案. 编写了将PCB制图软件输出格式文件转换为单片机程序和能够与单片机进行数据交互的转换程序软件. 选择合适的步进电机并设计了驱动电路.
