Reliability of large sized FPD panel handling robot
For large sized glass handling robot, reliability improving activity increases the importance. The activity is divided into two phases of design phase and line usage phase. At the design phase, accurate simulation for keeping the limitation of material or gear strength and accurate torque control are the key. At the line usage phase, supporting tool for preventive maintenance activity is the key. As the maintenance work itself is a hard work for large sized robot, a preventive maintenance is useful.
