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.
Claims6
A method for depositing a fluid over an interface, the method comprising:
- moving, by a dispensing device, the fluid within a chamber in a housing towards an exit of the chamber such that the fluid is dispensed through the exit of the chamber, wherein the chamber is configured to increase a tendency of the fluid to flow within the chamber;
- receiving the fluid from the exit of the chamber at an input of a nozzle located at a first end of a body of the nozzle;
- moving the fluid from the input through an arrangement of a plurality of channels located within the body such that the fluid exits the plurality of channels at an output of the nozzle located at a second end of the body, including:
- moving the fluid through a center channel located along a center axis that extends through the first end and the second end of the body of the nozzle, wherein the cross-sectional diameter of the center channel varies along a length that extends along the center axis;
- and
- moving the fluid through outer channels located away from the center axis around the center channel, wherein the cross-sectional diameter of each of the outer channels remains substantially constant along the center axis;
- controlling a flow of the fluid through the plurality of channels by a configuration of the plurality of channels, wherein the configuration comprises a diameter profile that includes the cross-sectional diameter for each of the plurality of channels;
- and
- depositing the fluid that exits the output of the nozzle over the interface to form a deposition having a desired shape.

A method for depositing a fluid over an interface using a nozzle, the method comprising:
- positioning the nozzle relative to the interface in which the nozzle comprises a body having a first end and a second end in which the second end of the body has a selected shape that allows the second end to be positioned within a desired distance from the interface;
- moving, by a dispensing device, the fluid within a chamber in a housing of a fluid dispensing system towards an exit of the chamber such that the fluid is dispensed through the exit of the chamber, wherein the chamber is configured to increase a tendency of the fluid to flow within the chamber;
- receiving the fluid within a cavity in a first section of the body from the exit of the chamber through an input of the nozzle;
- moving the fluid from the cavity in the first section through an arrangement of a plurality of channels in a second section of the body such that the fluid exits the plurality of channels at an output of the nozzle located at the second end of the body, including:
- moving the fluid through a center channel located along a center axis that extends through the first end and the second end of the body of the nozzle, wherein the cross-sectional diameter of the center channel varies along a length that extends along the center axis;
- and
- moving the fluid through outer channels located away from the center axis around the center channel, wherein the cross-sectional diameter of each of the outer channels remains substantially constant along the center axis;
- controlling a flow of the fluid through the plurality of channels by a configuration of the plurality of channels, wherein the configuration comprises a diameter profile that includes the cross-sectional diameter for each of the plurality of channels;
- and
- depositing the fluid that exits the output of the nozzle over the interface to form a deposition 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.
