In this paper, the design of PLC based control of three degrees of freedom manipulator control spray system to spray paint a simple manipulator kinematics analysis, the establishment of a system model, the completion of the sensor, stepper motor, controller selection; the use of programmable robot controller to control the PLC to select the right model, I conducted the distribution of IO, the preparation of the single-cycle operation for automatic operation, manual, back to the origin and control procedures, such as an online simulation, to observe the operation procedures and analyze the problems, a process optimization; to state software industrial MCGS group as a platform to monitor the development of a host computer interface and control procedures for the preparation of the part. In the system design, has adopted a self-locking, interlocking, such as the reliability of the corresponding measures to reduce the impact of interference, and ensure the normal operation of the system.
Completed the preliminary design of the painting robot design, designed to meet the graduation requirements, but because of time constraints, all aspects of robot performance yet to be improved.
