Mechanical Structure Design of Vacuum Holder Disk Head Cleaning Machine


Article Preview

In the production process of disk head on the computer hard disk, although the strict control have been progressing on the environment and the working procedure by production factory, it’s still difficult to make cleanliness of the products reach the requirement of hard drive assembly. Because the working procedure is complex, the pollution source is broader, and the cleanliness standard has been raised to the " without any particle under the 200 times magnifying glass ", which is to meet the increase of the hard disk capacity. This paper designed the mechanical structure of a new machine for cleaning disk head. It uses vacuum to hold disk head instead of grid, and combines spray cleaning, scrub, scouring, ultrasonic cleaning, drying, with electromagnetic valve to control vacuum degree in the vacuum tubes and fixture. Thus this machine cleans disk head to improve its cleanliness.
