Abstract:
1. A robotic end-effector for high-speed precision alignment and assembly of a spacer ring onto a motor-hub assembly comprising: a vacuum holding device operable for temporarily holding said spacer ring, whereby said spacer ring is to be aligned and assembled to said motor-hub assembly, said holding device comprising a datum feature for abutting said spacer ring to said holding device; a course alignment device operable for locating said holding device with respect to a locating feature coupled with said motor-hub assembly; a refractor operable for disengaging said course alignment device from said locating feature; and a moveable base whereby lateral compliance is provided for said holding device, enabling motion of said spacer ring with respect to said motor-hub assembly, thereby enabling fine alignment of said spacer ring with said motor-hub assembly when said motor-hub assembly touches said spacer ring, wherein said movable base is disposed above said vacuum holding device and configured to move orthogonal to said vacuum holding device.
