Development of Robot Control Method for Curved Seal Extrusion 982366

The glass-integrated Curved Seal Extrusion (hereafter called “CSE”) is a new technology for manufacturing automobile-window mole. This technology is to extrude and stick mole directly on 3-D shaped window-glass by using the combination of a multi-axes robot and an extruding machine. This process could not be realized through the previous robot technology whose primary purpose was transporting goods, which did not necessitate real-time speed control. This time, we adopted a robot for the purpose of processing plasticity molding. For the purpose of improving formability, productivity, and appearance quality, we optimized the robot's movements and devised a method to vary the molding speed of the extruding machine. Furthermore, we have established a mass production technology by developing the optimum robot control method. This method includes: 1)servo float function, 2)simultaneous control of the robot movement and the extruding machine's rotation, 3)locus and speed control of extruding point.
