Abstract

At present, the cleaning of disk packs (9 disks) in manufacturing assembly is done by contact cleaning with a wiping cloth. A set of 10 arms is mounted on a fixture' Each arm is manually wrapped with cleaning cloth. The cleaning takes place by wiping and moving the arms toward the center of the rotating disk pack. The re-wrapping with new cleaning cloth for every disk pack is very time consuming (10 minutes for every disk pack).

Non-contact Cleaning Device for Magnetic Disk Packs

At present, the cleaning of disk packs (9 disks) in manufacturing assembly is done by contact cleaning with a wiping cloth. A set of 10 arms is mounted on a fixture' Each arm is manually wrapped with cleaning cloth. The cleaning takes place by wiping and moving the arms toward the center of the rotating disk pack. The re-wrapping with new cleaning cloth for every disk pack is very time consuming (10 minutes for every disk pack).

Proposed here is a non-contact cleaning device consisting of 10 arms (structured as one component with 9 slots). Each arm carries an air pressure and vacuum channels, and supports the air cleaning head.

A single arm with a double-sided air cleaning head was built and tested successfully. As illustrated in the figures, it was structured with air nozzle slots and vacuum nozzles. Excellent surface cleaning was obtained by moving the cleaning heads toward the center of the disk pack in and out as the disks rotated.
