Structural Design of Multi-purpose Pneumatic Robot

Abstract

At first, the paper introduces the conception of the industrial robot and the Eller. Dairy  information of the development briefly. What’s more, the paper accounts for the background and the primary mission of the topic. The paper introduces the function, composing and classification of the manipulator, tells out the free-degree and the form of coordinate. At the same time, the paper gives out the primary specification parameter of this manipulator,The paper designs the structure of the hand and the equipment of the drive of the manipulator. This paper designs the structure of the wrist, computes the needed moment of the drive when the wrist wheels and the moment of the drive of the pump.The paper designs the structure of the arm.The paper designs the system of air pressure drive and draws the work principle chart, the manipulator uses PLC to control. The paper institutes two control schemes of PLC according to the work flow of the manipulator. The paper draws out the work time sequence chart and the trapezium chart. What’s more, the paper workout the control program of the PLC.

KEY WORDS:  industrial robot manipulator pump air pressure drive   PLC
