Publication number: 20180085772Abstract: A fluid dispense tip includes a bevel at an opening to reduce the amount of surface tension, or “land”, at the opening. The bevel is formed by grinding in a longitudinal direction such that any tooling scars resulting from the grinding operation are likewise longitudinally oriented, further reducing the amount of surface tension in the tip, thereby leading to heightened dispensing accuracy. The tip may be machined from stock as a unitary piece, to increase its lifetime, and may be formed with a bore of a relatively large diameter that is tapered down to a smaller diameter near the tip opening, to allow for delivery of fluid through the tip body at a decreased pressure. A cleaning tool may be provided for removing residual material from the inner surfaces of the tip. A removable liner sleeve may be provided within the bore to reduce the effective inner diameter of the dispense tip.Type: ApplicationFiled: November 29, 2017Publication date: March 29, 2018Inventor: Jeffrey Fugere

Patent number: 7448857Abstract: In a fluid pump and cartridge assembly, a cartridge includes a material inlet port, a material outlet port, and a feed screw. The feed screw delivers fluid to be dispensed from the fluid inlet to the outlet port. The fluid inlet is preferably elongated in a direction along a longitudinal axis of the feed screw to enhance consistency in material flow through the cartridge. The feed screw is preferably driven by a closed-loop servo motor to achieve high-performance dispensing resolution. The assembly is preferably compatible with fixed-z and floating-z cartridges.Type: GrantFiled: January 18, 2005Date of Patent: November 11, 2008Assignee: DL Technology, LLCInventor: Jeffrey Fugere

The feed screw is preferably driven by a closed-loop servo motor to achieve high-performance dispensing resolution. The assembly is preferably compatible with fixed-z and floating-z cartridges. A optional vented dispense tip, in combination with the fluid pump, allows for repeatable deposit of fillet patterns while maintaining optimal consistency. A dispense controller allows for reverse-compatibility such that the fluid pump of the present invention can be mounted to, and controlled by, conventional pump position controllers.Type: ApplicationFiled: November 15, 2004Publication date: May 12, 2005Inventor: Jeffrey Fugere

Patent number: 6299078Abstract: In a dispense tip adapter system, an adapter unit provides for compatibility between high-performance dispensing needles and conventional dispensing pump systems. The dispensing pump includes an outlet through which dispensed material is delivered, and includes an output body with alignment pins extending therefrom and first threads about the body. The dispensing needle includes a longitudinally-disposed body and neck, the body and neck including a longitudinal port providing a path for delivery of the dispensed material through the dispensing needle. The body of the dispensing needle includes an outer surface that is keyed for angular positioning of the needle with respect to the pump. The adapter includes an alignment plate, and index plate and an adapter nut. The alignment plate comprises a plurality of alignment holes for mating with the alignment pins, a material aperture aligned with the pump outlet, and a plurality of index pins extending from the body of the alignment plate.Type: GrantFiled: May 17, 2000Date of Patent: October 9, 2001Assignee: Bradford Labs LLCInventor: Jeffrey Fugere
