用于办公室的全自动化印章机的设计与开发—电路与控制系统设计

The design and development of the fully automatic seal machineused in the office circuit and control system designAbstractWith the continuous development of modern technology and industry,and thegradual deepening of industrial products and technology,from industry 1.0 to industry3.0,people have higher and higher requirements for portable office equipment.Nowadays,human life has become more and more inseparable from theautomation equipment.No matter what age and occasion,automation equipment canbe seen everywhere.However,there are not many automation equipment to liberateworkers'physical strength and relevant data record usage in the aspect of not strikingpeople's seals.There are certain hidden dangers in the safety problems.Through fouryears of study and life in the University,I feel that many places still use manual sealsFor example,the Academic Affairs Office of the university needs to help students togo to school,graduate and career guidance with seals,which not only consumesphysical strength but also wastes time.This design mainly analyzes the types anddevelopment trend of the automatic seal machine at home and abroad.Aiming at theimprovement of the existing automatic seal machine,it focuses on the office crowd.Itcan not only solve the problem of manual seal of the teachers in the enrollment andEmployment Department of the school,release the hands and time of the office staff,but also solve the safety problem of the office supplies,which can be viewed Usepermission can also be set for used records to improve the security level of officepersonnel's operations.This group will combine the mechanical principle,mechanical design basis,C#,air pressure and hydraulic transmission and other professional knowledge learned inthe University for four years,and design an automatic seal machine with authorityidentification after research.The whole control system consists of air pump,pressureregulating valve,solenoid valve,air cylinder,IO module,etc.The IO module isdebugged to enable the upper computer to communicate with the seal machinethrough serial port,and the form execution program is compiled by C#,so that theprogram designed by the software in C#,can communicate with the IO module.The
