Abstract: A device for loading a first and second head gimbal assemblies (HGAs) onto an actuator pivot flex assembly (APFA) of a hard disk drive may comprise a gripper configured to grip the HGAs and to move them between the first and second actuator arms of the APFA. A swage key may be moved to a first position such that first and second distal portions thereof are respectively disposed between the first and second HGAs, and to a second position such that the HGAs are supported, respectively, by first and second localized humps defined on the swage key and aligned with boss holes of the APFA. The swage key may be moved to a third position such that the HGAs face first and second proximal portions of the swage key and become seated onto the boss holes.

Abstract: A device may comprise a machine vision system in a first zone of the device. The machine vision system may be configured to provide measurements of gaps between selected portions of a head gimbal assembly (HGA) and selected portions of arms of a head stack assembly (HSA) of a data storage device. A first adhesive tacking system may be provided in a second zone of the device, and configured to sequentially apply adhesive to the gaps based upon the measurements of the gaps provided by the machine vision system. A transport mechanism may be configured to sequentially carry the HSA of the data storage device to the first zone to enable the machine vision system to measure the gaps and from the first zone to the second zone of the device to enable the first adhesive tacking system to apply the adhesive to the gaps.
