Abstract

A system is described for cleaning fasteners which are used in the assembly of apparatus in which particulate contamination is detrimental, such as magnetic disk files, for example. The cleaning apparatus comprises a holding system in which fasteners, such as screws or bolts, are held for a cleaning operation and for a subsequent assembly operation. The holding system comprises a plurality of holders 1 made of two parallel spaced rods 2. The screws or bolts 3 are loaded into the holder, by a vibratory feeder, for example, so that the screws or bolts hang vertically. The bottom of the screw head supports the entire screw by resting upon the two horizontal rods 2, and the screws 3 hang vertically so that the bottom threaded section can slide freely between the two rods 2.

Cleaning Method and Apparatus

A system is described for cleaning fasteners which are used in the assembly of apparatus in which particulate contamination is detrimental, such as magnetic disk files, for example. The cleaning apparatus comprises a holding system in which fasteners, such as screws or bolts, are held for a cleaning operation and for a subsequent assembly operation. The holding system comprises a plurality of holders 1 made of two parallel spaced rods 2. The screws or bolts 3 are loaded into the holder, by a vibratory feeder, for example, so that the screws or bolts hang vertically. The bottom of the screw head supports the entire screw by resting upon the two horizontal rods 2, and the screws 3 hang vertically so that the bottom threaded section can slide freely between the two rods 2. The slot created by the two rods is small enough to prevent the head of the screws from slipping through, and a thin rod 4 is placed parallel to the holder above the screws to secure them so that the system can be placed in any orientation without losing parts. The screws are held in the holders during the cleaning process which involves a mechanical transport system which transports the screws in holders to a series of tanks for separate cleaning operations in which cleaning is accomplished by ultrasonic energy techniques. The screws are maintained in their clean condition in the holders and a plurality of the holders may be stacked for use in the assembly process wh...
