production efficienc,yand guarantee the product quali.tAy s an important part of the
automation production line, industrial robots are gradually approved and adopted by
enterprises. The technique level and the application degree of industrialrobots reflect the
national level of the industrialautomationto some extent, currently, industrialrobots mainly
undertake the jops of welding, spraying, transporting and stowing etc. , which are usually done
repeatedly and take high work strength, and most of these robots work in playback. way
In this paper I will design an industrial robot with four DOFs, which is used to
carry material for a punch. First I will design the structure of the base, the big arm, the small arm
and the end manipulator of the robot, then choose proper drive method and transmission method,
building the mechanicalstructure of the robot. On this foundation,I will design the control
system of the robot, includingchoosing DAQ card, servo control, feedback method and
designing electric circuit of the terminal card and control software. Great attentwioinll be paid
on the reliability of the control software and the robot safety during running. The aims to realize
finally include: servocontrol and brake of the joint, monitoringthe movementof each joint in
realtime, playback programming and modifying the program online, setting reference point and
returning to reference point.
