Discharge Regulator of Painting Robot and Establishment of CAD Teaching System 881747
The current spray painting system is hardly considered that the thickness is controlled enough, because the temperature greatly influence on the viscosity of paint. We noticed the problem and detected the temperature at a nozzle of a spray unit. We tried that the paint flow is controlled to get stable thickness more accurately by the temperature feedback system. We also tried to develop the new programming method of robots. This new offline programming system provided us an ideal positions and orientations of the spray gun mounted on a robot wrist, after several simulation in the CAD system. We checked and debugged the office taught date with a trial robot in a trial area, and then loaded down with the date to a target robot. We eventually provided a better production technology with the paintflow control system together with the new CAD based offline programming system. It shortened the programming time to 1/3 and working time to 1/10 at the production line, which disturb the car production.
