Abstract

This article describes an apparatus and method suitable for use in the fabrication of multinozzle array wafers. Such wafers are generally used in the fabrication of multinozzle drop generators. The apparatus includes a nozzle holder 12. The nozzle holder 12 is fabricated from a pair of planar members 14 and 16. Each of the planar members is fitted with an L-shaped slot. The glass nozzles 18 are fitted within the L-shaped slot. One of the planar members is fixedly coupled to a movable support 20. The support is hingedly coupled to a horizontal table 22. Table 22 is coupled to a vibratory source (not shown). A weight is fixedly coupled to the top of planar member 14.

Apparatus and Method for Manufacturing Multiple Glass Nozzle Arrays

This article describes an apparatus and method suitable for use in the fabrication of multinozzle array wafers. Such wafers are generally used in the fabrication of multinozzle drop generators.

The apparatus includes a nozzle holder 12. The nozzle holder 12 is fabricated from a pair of planar members 14 and 16. Each of the planar members is fitted with an L-shaped slot. The glass nozzles 18 are fitted within the L-shaped slot. One of the planar members is fixedly coupled to a movable support 20. The support is hingedly coupled to a horizontal table 22. Table 22 is coupled to a vibratory source (not shown). A weight is fixedly coupled to the top of planar member 14.

In operation, the glass tubes 18 are fitted in the L-shaped slots, and the tube holder is attached to support 20. The support 20 is raised up and down in the direction shown by two-headed arrow 21. Simultaneously with raising and lowering the fixture, the vibratory means vibrates the fixture and, as a result, the glass tubes are aligned in proper side by side relationship. Preferably, ultrasonic means is used to impart the vibratory motion to the assembly.
