Abstract: A comb gripper is disclosed for use in the assembly of a disk drive. The comb gripper may be used to push a comb tower of a shipping comb such that a head stack assembly (HSA) of the disk drive is rotated and a head gimbal assembly (HGA) of the disk drive is coupled to a ramp of the disk drive. The comb gripper may comprise: a first gripper finger that includes a protruding portion; a second gripper finger; and an actuator. The actuator may be configured to move the first and second gripper fingers, wherein the actuator is configured to move the protruding portion of the first gripper finger to contact the comb tower and to push the comb tower and the shipping comb such that the HSA is rotated and the HGA is coupled to the ramp.

Abstract: A device may comprise a gripper defining a plurality of openings, each being configured to selectively receive, retain and release an item using a vacuum. One or more sensors may be associated with the plurality of openings, and may be configured to detect a faulty item received in the opening associated therewith. An item receiving structure may be configured to receive items released by the gripper when one or more of the sensors detects that one or more of the received items is faulty. An item receptacle may be configured to receive a plurality of items, and a vacuum chute may be configured to convey items received in the item receiving structure away from the gripper and into the item receptacle under a vacuum force.

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.

Abstract: Disclosed is a cleaning device for cleaning a driver used in a disk drive manufacturing process. The cleaning device includes: a body; a replaceable cleaning pad mounted in the body; and a cover mounted to the body over the cleaning pad, in which, the cover includes an opening to receive the driver and to expose a portion of the cleaning pad to receive and clean the driver. The cleaning device further includes a cleaning pad rotation mechanism mounted in the body that connects to the cleaning pad and rotates the cleaning pad. The cleaning pad rotation mechanism is configured to rotate the cleaning pad such that an unused portion of the cleaning pad is exposed to the opening for receipt of the driver and the cleaning pad rotation mechanism may be activated to rotate the cleaning pad.

Abstract: A liquid dispense system for dispensing a 2-part epoxy resin compound to form bond beads having weights on the order of 1-20 mg. The dispensing system includes an epoxy resin compound pre-mixing and loading station, an epoxy dispense time and dispense force calibration station, and a plurality of epoxy dispensing third stations. Throughout the process, critical dispense related data is recorded on, and retrieved from, an on-board semiconductor memory device mounted on, and maintained with, the portable dispense syringe structure. Since the viscosity of the mixed epoxy compound is changing over time, any dispensing of constant amounts of the epoxy compound requires adjustments to dispense time and dispense force. These adjustments are made at a dispense station and are based on a calibration sample taken at the calibration station.
