In terms of industrial production and other fields, as a result of the working need，people often accept the factor damage such as the high temperature , corrosion and toxic gas, even life-threatening. The industry manipulator like this was born; the manipulator which is one of robot key components is in the industry robot assembly system the duty implementing agency. There are electrical machinery, switching power supply, electromagnetic valve, electronic device composition and so on. This equipment which is the integration of machinery model represents one of instruments has covered the programmable control technology, the positions control technology, the air operated technology and so on. This article introduced the manipulator, it outputs four groups by PLC to actuate the abscissa axis, the z-axis, the chassis rotation, hand-rotating motor separately, and controls the manipulator abscissa axis and the z-axis pint pointing, the micro switch bequeaths the position signal to the PLC main engine; The electrical machinery drives the hand fingernail and the chassis revolve; The solenoid valve controls air valve the switch to control the manipulator hand fingernail to gather, then realizes the manipulator proper motion function. This topic plans to develop the industry manipulator model, and it is to be possible to grasp and puts the object nimbly in the space, whose movement is diverse, it may replace human work in high temperature and the dangerous operation area, and may change there lasted parameters when it is necessary according to the work pieces changing and the movement flowing request.
Key words manipulator Programmable controller PLC position control step-electric motor.
