Vibration damping system for robot used e.g. for installing electric parts

摘要

The head piece travels on the Y axis support table in a X axis direction. The vibration insulation system includes vibration damping unit (10), which is arranged at the Y axis support table (1), and which damps the vibration produced by the stopping of the ball bearing worm shaft (3) and a X axis support table (6). With the assistance of a fluid resistance. The damping unit (10) has a connecting shaft (14) and a number of resistance blades (16) and is driven together with the worm shaft (3). A housing element (20) is filled with a viscous fluid (22). A pair of electrode plates (24a, 24b) is used for applying voltage to the viscous fluid, to achieve a charging of the viscous fluid.
