Abstract
Disclosed is a gripper for use with a disk clamp end effecter in a disk drive manufacturing process used for mounting a disk clamp to a disk in the manufacturing of a disk drive. The gripper comprises: a disk gripper housing, a lip seal gripper mounted to the disk gripper housing, and a vacuum channel. The lip seal gripper includes an upper portion that fits into the disk gripper housing and a lower portion that has a surface. The surface is configured to extend around the disk clamp to press against the disk clamp. The vacuum channel extends from the upper portion of the lip seal gripper to the lower portion of the lip seal gripper to provide a vacuum to the lip seal gripper such that the surface of the lip seal gripper is gripped by the vacuum to the surface of the disk clamp around the disk clamp.
