Design Of Nano Coating Machine

In today’s society, intelligent control technology has become more and more important, and has been widely used in people’s production and life. With the constant progress of the society and speeding up of life, people’s demand for products is becoming higher and higher. Intelligent products designed for actual has attracted more and more attention.This topic carry on the design according to the actual demand of chemical engineering institute of Inner Mongolia University. The overall system is divided into three parts, mechanical layer, configuration layer and circuit layer. Mechanical layer is composed of industrial aluminum material frame structures. The power source of the mechanical layer is provided by the stepper motor. Finish coating operation by the control of the stepping motor, using MCGS configuration touch screen as the upper machine in configuration layer. It communicates with circuit layer through RS232 interface circuit. And we protect the normal operation of communication by using standard Modbus protocol. The microcontroller of circuit layer is ATmega32. We control the whole system by using single chip microcomputer.This paper first carries on overall planning, design and component selection of the nano coating machine system according to the design requirements. Then it introduces the mechanical design of system, design of the configuration layer, design of circuit schematic, PCB production and the test of software program. The nano coating machine eventually meets the design requirements in all aspects through continuous testing and modification, and has certain stability.
