Paint robot system with precision hollow wrist
ABB Robotics' IRB 580 is a paint robot system that uses a high precision hollow wrist has a straight design that eliminates wear and tear on the paint- and air supply hoses, increasing the overall reliability. The wrist can rotate 140° in any direction and features an Integrated Process System (IPS) with closed loop regulation and high-speed control of paint and airflow adjustments. The paint process equipment is integrated in the robot arm to increase process response times and reduce paint and solvent waste. Synchronizing the paint flow triggering with the robot arm motion increases transfer efficiency and keeps overspray to a minimum.
The IPS will automatically compensate for physical changes in the environment or the equipment, always keeping the commanded flow rate within strict tolerances. This ensures a uniform film build with specified thickness. The result is high finish quality and optimum use of the paint material.
The IPS system monitors and warns the operator of equipment wear over time. It can also detect a broken cable or defective sensor and automatically enter open-loop production mode until it is convenient to enter the booth and perform the necessary maintenance.
