Abstract

A mist generating apparatus is provided for suppressing foreign material from becoming airborne prior to an application of a surface coat or treatment to a substrate. The assembly includes a frame assembly that may include a base mount and an intermediate mount movably coupled to the base mount. The apparatus includes an extension assembly movably coupled to the frame assembly and selectively positioned between a retracted position and an extended position. A manifold is coupled to the extension assembly, and the manifold is in fluid communication with a volatile liquid. The apparatus includes a spray nozzle in fluid communication with the manifold. The spray nozzle is configured for directing a mist of the volatile liquid to a portion of the substrate for at least temporarily suppressing foreign material.

First claim

What is claimed is:

1. A mist generating apparatus for suppressing foreign material from becoming airborne prior to an application of a surface coating or treatment to a substrate, the apparatus comprising:
a frame assembly;
an extension assembly comprising at least one guide rod, the extension assembly being movably coupled to the frame assembly and selectively positioned between a retracted position and an extended position;
a manifold coupled to the guide rod of the extension assembly, the manifold being in fluid communication with a volatile liquid;
a spray nozzle in fluid communication with the manifold, the spray nozzle being configured for directing a mist of the volatile liquid to a portion of the substrate for suppressing foreign material.

2. The mist generating apparatus according to claim 1 , wherein the frame assembly comprises a base mount and an intermediate mount, the intermediate mount being substantially parallel with and movably coupled to the base mount.

3. The mist generating apparatus according to claim 2 , wherein the extension assembly is movably coupled to the intermediate mount.

4. The mist generating apparatus according to claim 3 , wherein the extension assembly further comprises a first pneumatic cylinder.

5. The mist generating apparatus according to claim 4 , further comprising a second pneumatic cylinder configured to selectively move the intermediate mount with respect to the base mount.

6. The mist generating apparatus according to claim 2 , further comprising at least one linear guide rail assembly slidably coupling the intermediate mount to the base mount.

7. The mist generating apparatus according to claim 2 , wherein the base mount comprises an aluminum plate.

8. The mist generating apparatus according to claim 1 , further comprising a programmable logic controller configured to control an amount of volatile liquid expelled from the spray nozzle based on a geometry and dimensions of the substrate.

9. The mist generating apparatus according to claim 8 , wherein the amount of volatile liquid expelled from the spray nozzle is based on a spray time duration determined by the programmable logic controller.

10. The mist generating apparatus according to claim 1 , further comprising a combination of stainless steel and flexible supply lines coupled to the manifold.

11. A system for suppressing foreign material from becoming airborne prior to an application of a surface coating or treatment to a vehicle, the system comprising:
a first mist generating apparatus and a second mist generating apparatus, each mist generating apparatus comprising:
a frame assembly comprising a base mount and an intermediate mount movably coupled to the base mount;
an extension assembly comprising at least one guide rod, the extension assembly being movably coupled to the intermediate mount of the frame assembly and selectively positioned between a retracted position and an extended position;
a manifold coupled to the guide rod of the extension assembly, the manifold being in fluid communication with a volatile liquid; and
a spray nozzle in fluid communication with the manifold, the spray nozzle being configured for directing a mist of the volatile liquid;

a controller configured to:
direct the respective extension assemblies of the first and second mist generating apparatuses into the extended position and, in turn, position the respective spray nozzles into first and second interior portions of the vehicle when the vehicle is positioned adjacent the mist generating apparatuses; and
control an amount of volatile liquid expelled from each spray nozzle during a mist generating procedure.

12. The system according to claim 11 , wherein:
each spray nozzle remains in a stationary position with respect to the manifold during the mist generating procedure; and
the amount of volatile liquid expelled from each spray nozzle is based on a spray time duration predetermined by a programmable logic controller, and based on respective dimensions of the first and second interior portions of the vehicle.

13. The system according to claim 11 , wherein the base mount and the intermediate mount are substantially parallel.

14. The system according to claim 13 , wherein the extension assembly comprises a first pneumatic cylinder.

15. The system according to claim 14 , further comprising a second pneumatic cylinder configured to selectively move the intermediate mount with respect to the base mount.

16. The system according to claim 11 , further comprising a linear guide rail assembly slidably coupling the intermediate mount to the base mount of each mist generating apparatus.

17. The system according to claim 11 , further comprising a combination of stainless steel and flexible supply lines coupled to each manifold.

18. A mist generating apparatus for suppressing foreign material from becoming airborne prior to an application of a surface coating or treatment to a substrate, the apparatus comprising:
a frame assembly comprising a base mount and an intermediate mount, the intermediate mount being substantially parallel with and movably coupled to the base mount;
an extension assembly comprising at least one guide rod, the extension assembly being movably coupled to the intermediate mount of the frame assembly and selectively positioned between a retracted position and an extended position;
a manifold coupled to the guide rod of the extension assembly, the manifold being in fluid communication with a volatile liquid;
a spray nozzle in fluid communication with the manifold, the spray nozzle being configured for directing a mist of the volatile liquid to a portion of the substrate for suppressing foreign material.
