Abstract

A dauber assembly may comprise a manifold body comprising a first end configured to receive a nozzle, and a collar extending at least partially around the manifold body. The collar may comprise an inlet port. The manifold body may have one or more holes providing fluid communication between the inlet port of the collar and an outlet of a nozzle received by the first end of the manifold body.

First claim

The invention claimed is:

1 . A dauber assembly comprising:
a manifold body comprising a first end configured to receive a nozzle; and a collar extending at least partially around the manifold body, the collar comprising an inlet port; wherein the manifold body comprises a wall having one or more holes formed in a circumferential portion of the wall, the one or more holes providing fluid communication between the inlet port of the collar and an outlet of the nozzle when the nozzle is received by the first end of the manifold body; and wherein the manifold body comprises a projection extending from a second end of the manifold body, the projection is configured to be received in a tool holder, and the projection is nondetachably integral with the manifold body.

2 . The dauber assembly of claim 1 , wherein the collar is disposed rotatably about the manifold body.

3 . The dauber assembly of claim 2 , wherein the collar is configured to rotate at least 360 degrees about the manifold body.

4 . The dauber assembly of claim 1 , wherein the manifold body comprises a hollow cylinder configured to receive the nozzle at an interior of the first end of the manifold body, wherein an exterior of the hollow cylinder has a circumferential groove, and wherein the one or more holes are disposed in the circumferential groove.

5 . The dauber assembly of claim 4 , wherein the hollow cylinder is configured to threadedly receive the nozzle.

6 . The dauber assembly of claim 1 , wherein the one or more holes include at least three holes.

7 . The dauber assembly of claim 1 , wherein the first end of the manifold body is configured to receive the nozzle such that the nozzle is coaxial with a longitudinal axis defined by the projection, and the inlet port is oriented transverse to the longitudinal axis.

8 . The dauber assembly of claim 1 , wherein the manifold body further comprises a flange extending radially from the manifold body between the collar and the projection, such that the flange is configured to inhibit motion of the collar toward the projection.

9 . An adapter for a dauber nozzle, the adapter comprising:
a body comprising a wall defining a hollow interior, the body having an outlet configured to receive an inlet portion of the dauber nozzle; a protrusion extending from the body and configured to be received in a holder, wherein the protrusion is formed as a single piece with the body; and a collar extending around at least a portion of a circumference of the body, the collar including an inlet stem; wherein the wall of the body has a plurality of openings formed in a circumferential portion of the wall of the body, and the inlet stem of the collar is in fluid communication with the outlet of the body via the plurality of openings and the hollow interior of the body.

10 . The adapter of claim 9 , wherein the collar and the body are configured to rotate relative to each other.

11 . The adapter of claim 9 , wherein the wall of the body comprises a cylinder having a circumferential groove and the plurality of openings are disposed in the circumferential groove.

12 . The adapter of claim 11 , wherein the circumferential groove has a rounded cross-sectional profile.

13 . The adapter of claim 9 , wherein the inlet stem comprises a barbed nipple.

14 . The adapter of claim 9 , further comprising a flange extending radially from the body between the collar and the protrusion, such that the flange is configured to inhibit motion of the collar toward the protrusion.

15 . A method for applying sealant, the method comprising:
coupling a mounting protrusion of a manifold body to a holder, wherein the mounting protrusion is formed as a single integral piece with the manifold body; receiving a sealant at a hollow interior of the manifold body via a tubular stem, wherein the hollow interior of the manifold body is defined by at least one wall of the manifold body and the at least one wall has an opening formed in a circumferential portion of the wall and configured to provide fluid communication between the hollow interior and the tubular stem, wherein the tubular stem extends from a collar disposed around the manifold body and configured to rotate around the manifold body, and the tubular stem has an inlet coupled to a sealant source; and dispensing the sealant from a dauber nozzle received in the hollow interior of the manifold body.

16 . The method of claim 15 , wherein the collar is disposed around an entirety of a circumference of the manifold body.

17 . The method of claim 15 , further comprising spreading the dispensed sealant on a surface of a workpiece by rotating the manifold body at least a quarter turn relative to the tubular stem.

18 . The method of claim 15 , wherein the holder is a holder of an end effector of a robotic arm.

19 . The method of claim 15 , wherein the holder is a tool holder.
