Abstract
Methods and devices include performing a flush routine along a fluid line connectable from a fluid reservoir to a fluid dispensing location of a substrate material, drawing a predetermined fluid from the reservoir through the fluid line, positioning a foot component of a fluid dispensing component on a predetermined dispensing surface relative to the fluid dispensing location, dispensing a predetermined volume of a fluid from the fluid reservoir at the fluid dispensing location on the substrate material, and removing the positioned foot component from the predetermined dispensing surface.
Claims18
A method, comprising:
- performing a flush routine along a fluid line connectable from a fluid reservoir to a fluid dispensing location of a substrate material;
- drawing a predetermined fluid from the reservoir through the fluid line;
- positioning a foot component of a fluid dispensing component on a predetermined dispensing surface relative to the fluid dispensing location;
- dispensing a predetermined volume of a fluid from the fluid reservoir at the fluid dispensing location on the substrate material;
- and
- removing the positioned foot component from the predetermined dispensing surface.
A fluid dispensing system, comprising:
- a reservoir for retaining a predetermined type of fluid;
- a pumping mechanism in fluid contact with the reservoir to selectively dispense a predetermined volume of fluid from the reservoir;
- and
- a dispensing component in fluid communication with the pumping mechanism for dispensing a plurality of the predetermined volume of fluid from the reservoir, each predetermined volume dispensed at a corresponding position on a surface of a substrate material;
- wherein the dispensing component includes a foot component and a needle component in a fixed position relative to the dispensing component, the foot component configured to contact the surface of the substrate material prior to each predetermined volume dispensed at the corresponding position on the surface of the substrate material, and further
- wherein the needle component is configured to dispense each predetermined volume of fluid on the substrate material.
