基于PLC的机械手分拣控制系统设计

Automatic sorting line PLC control system designAbstract:In today's life,science and technology,the development of the new moon,themanipulator in the advanced manufacturing field plays an extremely important role,it can carrygoods,sorting goods,can realize the mechanization and automation of production,can be used toprotect the safety of human body,the application will be more and more widely.The application ofmechanical arm is also more and more extensive.The machine is a kind of high-tech automaticproduction equipment which has been developed in recent decades.It is widely used in machinerymanufacturing,metallurgy,electronics,light industry and atomic energy.In this paper,based on the development of mechanical hand in recent years,combined withthe design of the manipulator,the mechanical hand technology is analyzed,and the design schemeof pneumatic drive and PLC control is proposed.Using the holistic design idea,considering thecharacteristics of the software and the hardware,the software and the hardware arecomplementary and optimized.The whole structure,drive system,the structure and control systemof the material sorting manipulator are analyzed and designed.In its drive system,the controlsystem of the PLC control unit is used to complete the initialization of the system function,themovement of the manipulator,the fault alarm,the sorting and other functions.At last,a simple,easy to implement,and the theoretical significance of the control strategy is proposed.Through the work above,it is concluded that the economic,practical,high reliable materialsorting manipulator design scheme,the design of PLC control system in other economic type alsocertain reference value.Keywords:manipulator touch screen (HMI);programmable logic controller (PLC);automaticcontrol;sorting materials
