Abstract
A method and apparatus for depositing a fluid over an interface. A nozzle may comprise a body having a first end and a second end, an input located at the first end of the body, an output located at the second end of the body, and a plurality of channels located within the body. The input may be configured to receive a fluid. The plurality of channels may have a configuration that causes the fluid received through the input to flow through the plurality of channels and exit the output to form a deposition having a desired shape over an interface.
Claims14
An apparatus comprising:
- a housing having a chamber configured to receive a fluid in which the chamber is configured to increase a tendency of the fluid to flow within the chamber;
- a dispensing device configured to move the fluid in the chamber towards an exit of the chamber such that the fluid is dispensed through the exit of the chamber;
- and
- a nozzle comprising:
- a body having a first end and a second end;
- an input located at the first end of the body and configured to receive the fluid from the exit of the chamber;
- an output located at the second end of the body;
- and
- a plurality of channels located within the body in which the plurality of channels has a configuration that causes the fluid received through the input to flow through the plurality of channels and exit the output to form a deposition having a desired shape over an interface, wherein the configuration of the plurality of channels comprises:
- a diameter profile that includes a cross-sectional diameter for each of the plurality of channels;
- and
- an arrangement of the plurality of channels relative to each other and relative to the second end of the body, wherein the arrangement is selected such that the plurality of channels includes a center channel located along a center axis that extends through the first end and the second end of the body of the nozzle and outer channels located away from the center axis around the center channel, wherein the diameter profile is selected such that the cross-sectional diameter of the center channel varies along a length that extends along the center axis and the cross-sectional diameter of each of the outer channels remains substantially constant along the center axis.

- a dispensing device configured to move the fluid in the chamber towards an exit of the chamber such that the fluid is dispensed through the exit of the chamber;
- and
- a nozzle comprising:
- a body having a first end and a second end in which the body includes a first section that extends from the first end to a plane through the body and a second section that extends from the plane to the second end of the body;
- a plurality of channels located within the body and having a plurality of openings in which the plurality of channels has a configuration that includes a diameter profile and an arrangement, wherein the diameter profile includes a cross-sectional diameter of a center channel located along a center axis that extends through the first end and the second end of the body, and a cross-sectional diameter of outer channels, and wherein the cross-sectional diameter of the center channel varies along a length that extends along the center axis and the cross-sectional diameter of each of the outer channels remains substantially constant along the center axis;
- an input located at the first end of the body and configured to receive the fluid from the exit of the chamber;
- a cavity configured to receive the fluid from the input;
- and
- an output located at the second end of the body and formed by the plurality of openings of the plurality of channels in which the configuration of the plurality of channels causes the fluid flowing through the plurality of channels to exit the output with a desired velocity profile and a desired pressure profile to form a deposition having a desired shape over an interface in which the interface is selected from one of a seam interface, a cross-seam interface, a fastener interface, a corner interface, and a step interface.
