Research On Automatic Cleaning And Sterilization Equipment Of Mahjong Brand Based On STM32 Control

According to the actual needs of the market,this paper designs a mahjong brand cleaning and sterilization equipment.According to the practical requirements of mahjong cleaning,the mechanical structure and functional modules of the equipment are determined.According to the actual control needs,the control system is designed,and the working effect of the equipment is verified by a prototype.This equipment started from the tilting mahjong brand cleaning sterilization equipment,after three times of mechanical structure changes and upgrades,the final modular mahjong brand cleaning sterilization equipment structure plan.In this paper,the working mode of the spray system and sterilization system included in the modular mahjong cleaning and sterilization equipment is studied.According to the requirements of product design,the prototype production of rotating box mahjong cleaning equipment was carried out,and the experiment of prototype cleaning was carried out.Hardware circuit design and software driver writing is one of the important guarantee to realize automatic control equipment,according to the actual control of modular mahjong tiles cleaning sterilization equipment,equipment selection to ARM as the core of the STM32 microprocessor as the core.According to the control requirements of the equipment,the construction of related peripheral circuits and the preparation of control procedures.The frame of the equipment is equipped with a proximity switch.Through the coordinated action with the stepping motor,the rotating state of the equipment is induced.Equipment internal integration module and ultraviolet disinfection lamp of anion generator and by liquid storage tank,water pump,and spray cleaning module of drainage tube,high equipment integration,convenient maintenance and management.The equipment carries out the transmission of power and information through the conductive slip-ring for the relevant devices inside the rotating box.Modular mahjong card cleaning sterilization equipment,through the drawer can be convenient to achieve card loading,card picking.The cleaning of mahjong tiles can be completed through the process of spraying,transferring,sterilizing and space purification of cleaning agents.After analyzing the actual working effect of the cleaning experiment of mahjong brand cleaning equipment sample machine,the cleaning effect of mahjong brand meets the design requirement.Compared with the previous mahjong brand cleaning equipment,it has the advantages of rich functional modules,small size,high cleaning efficiency,simple operation and low production cost,and has high market promotion value.
