Abstract

A nozzle for dispensing adhesive between a first part and a second part comprises a nozzle body. The nozzle body comprises a first-part engagement surface. The nozzle body also comprises a second-part engagement surface, contiguous with the first-part engagement surface and defining an engagement-surface angle, greater than 0° and less than 180°, with a virtual plane, coincident with the first-part engagement surface. The nozzle body further comprises a nozzle-body outlet port, formed in the second-part engagement surface. The nozzle body additionally comprises a nozzle-body inlet port, formed in the first-part engagement surface. The nozzle also comprises a separator plate, coupled with and extending from the nozzle body.

First claim

What is claimed is:

1. A nozzle for dispensing adhesive between a first part and a second part, the nozzle comprising:
a nozzle body, comprising:
a first-part engagement surface;
a second-part engagement surface, contiguous with the first-part engagement surface and defining an engagement-surface angle, greater than 0° and less than 180°, with a virtual plane, coincident with the first-part engagement surface;
a nozzle-body outlet port, formed in the second-part engagement surface; and
a nozzle-body inlet port, formed in the first-part engagement surface; and

a separator plate, coupled with and extending from the nozzle body.

2. The nozzle according to claim 1 , wherein the nozzle-body outlet port and the nozzle-body inlet port lie in different planes.

3. The nozzle according to claim 2 , wherein the separator plate extends from the nozzle body along another virtual plane, parallel to or containing the first-part engagement surface.

4. The nozzle according to claim 3 , further comprising a wiper, coupled to the nozzle body and extending away from the first-part engagement surface in a direction, perpendicular to the first-part engagement surface, wherein the wiper is more flexible than the nozzle body.

5. The nozzle according to claim 4 , wherein the wiper further extends away from the second-part engagement surface in a direction, perpendicular to the second-part engagement surface.

6. The nozzle according to claim 4 , further comprising an overflow pocket, defined by the wiper and the first-part engagement surface of the nozzle body, wherein the nozzle-body inlet port is in fluidic communication with the overflow pocket.

7. The nozzle according to claim 6 , further comprising a secondary overflow pocket, defined by the wiper and the second-part engagement surface of the nozzle body, wherein:
the nozzle body further comprises a second nozzle-body inlet port, formed in the second-part engagement surface; and
the second nozzle-body inlet port is in fluidic communication with the secondary overflow pocket.

8. The nozzle according to claim 1 , wherein the engagement-surface angle between the second-part engagement surface and the virtual plane, coincident with the first-part engagement surface, is less than 90°.

9. A system for dispensing adhesive between a first part and a second part, the system comprising:
a nozzle, comprising:
a nozzle body, comprising:
a first-part engagement surface;
a second-part engagement surface, contiguous with the first-part engagement surface and defining an engagement-surface angle, greater than 0° and less than 180°, with a virtual plane, coincident with the first-part engagement surface;
a nozzle-body outlet port, formed in the second-part engagement surface; and
a nozzle-body inlet port, formed in the first-part engagement surface; and

a separator plate, coupled with and extending from the nozzle body;

a reservoir, fluidically coupled with the nozzle-body outlet port;
a vacuum source, fluidically coupled with the nozzle-body inlet port; and
a vehicle, supporting the nozzle.

10. The system according to claim 9 , wherein:
the vehicle comprises a crawler that is selectively movable relative to the reservoir and the vacuum source; and
the nozzle is coupled to the crawler such that movement of the crawler, relative to the reservoir and the vacuum source, correspondingly moves the nozzle relative to the reservoir and the vacuum source.

11. The system according to claim 10 , wherein the crawler comprises:
wheels; and
a motor, coupled to at least one of the wheels and selectively operable to rotate at least the one of the wheels.

12. The system according to claim 9 , wherein:
the vehicle comprises a robotic arm;
the nozzle is coupled to the robotic arm; and
the robotic arm is configured to move the nozzle relative to the reservoir and the vacuum source.

13. The system according to claim 9 , wherein:
the vehicle comprises a handle that is manually movable relative to the reservoir and the vacuum source; and
the nozzle is coupled to the handle.

14. The system according to claim 9 , wherein:
the vehicle comprises an articulated structure, comprising segments;
adjacent ones of the segments are coupled to each other, such that the adjacent ones of the segments are pivotable, relative to each other, about a first axis and a second axis; and
the first axis is perpendicular to the second axis.

15. The system according to claim 9 , further comprising a sensor, coupled to the vehicle and movable relative to the nozzle.

16. The system according to claim 9 , further comprising:
a magnetic coupling assembly, coupled to the vehicle and comprising:
a first magnetic coupler, attached to the vehicle; and
a second magnetic coupler, magnetically coupleable to the first magnetic coupler; and

a sensor, attached to the second magnetic coupler.

17. The system according to claim 9 , further comprising:
a magnetic coupling assembly, coupled to the vehicle and comprising:
a first magnetic coupler, attached to the vehicle; and
a second magnetic coupler, magnetically coupleable to the first magnetic coupler;
a heat source, attached to the second magnetic coupler; and
an infrared camera, attached to the second magnetic coupler, such that the infrared camera is stationary relative to the heat source.

18. The system according to claim 9 , wherein the vehicle comprises a roller, rotatable relative to the nozzle.

19. The system according to claim 18 , wherein the vehicle further comprises a roller-biasing spring, coupled to the roller and configured to bias the roller away from the vehicle.

20. The system according to claim 9 , further comprising a biasing member, coupled to the nozzle and configured to bias the separator plate away from the vehicle.
