Abstract

An applicator assembly for treating a surface includes a material applicator configured to dispense a treatment material on a surface and an applicator clamp configured to support and position a dispensing end of the material applicator. An applicator tip is inserted into a dispensing aperture formed in the applicator clamp, and the applicator tip is configured to receive the treatment material from the dispensing end of the material applicator. The applicator assembly further includes an applicator bracket configured to slidably attach the material applicator and applicator clamp to an assembly support frame. Additionally, an automated applicator actuator operatively attached to the assembly support frame and applicator bracket manipulates the applicator bracket between a first position and a second position.

First claim

What is claimed is:

1. An applicator assembly comprising:
an assembly support frame;
a material applicator configured to selectively dispense a treatment material on a surface;
an applicator clamp forming an interior space and having a dispensing aperture, the applicator clamp configured to support and position a dispensing end of the material applicator within the interior space;
an applicator tip being formed from an absorbent material and inserted into the dispensing aperture of the applicator clamp, the applicator tip including an interior portion and an exterior portion, the interior portion extending into the interior space and aligned with the material applicator such that the interior portion of the applicator tip absorbs the treatment material dispensed by the material applicator, the exterior portion extends from the dispensing aperture to an exterior position and the exterior portion applies the treatment material along a surface to be treated;
an applicator bracket attached to the material applicator and the applicator clamp, the applicator bracket configured to slidably attach the material applicator and the applicator clamp to the assembly support frame; and
an automated applicator actuator operatively attached to the assembly support frame and the applicator bracket, the automated applicator actuator configured to manipulate the applicator bracket between a first position and a second position.

2. The applicator assembly of claim 1 , further comprising:
a controller; and
at least one sensor operatively attached to the applicator clamp and the controller, wherein the controller is communicably coupled to the automated applicator actuator and the at least one sensor, wherein the at least one sensor is configured to sense and scan the surface and produce a surface data set that includes a distance measured between the applicator clamp and the surface, and the controller is programmed to operate the automated applicator actuator to manipulate the applicator bracket based on the surface data set.

3. The applicator assembly of claim 1 , further comprising one or more surface engaging members attached to the applicator clamp, wherein when the applicator bracket is in the second position, the one or more surface engaging members are configured to engage the surface such that the applicator tip maintains a constant contact point at a fixed height relative to an application point of the application tip.

4. The applicator assembly of claim 1 , wherein the dispensing end of the material applicator is aligned with the dispensing aperture of the applicator clamp, and the dispensing end is positioned a fixed distance away from the applicator tip.

5. The applicator assembly of claim 1 , wherein the applicator clamp includes a raised lip formed within the interior space, the raised lip configured to surround a perimeter of the dispensing aperture to isolate the applicator tip from an excess of the treatment material delivered by the material applicator.

6. The applicator assembly of claim 1 wherein the dispensing aperture includes at least one applicator tip holder arranged around a lateral surface of the dispensing aperture, and wherein the at least one applicator tip holder is configured to securely hold the applicator tip within the dispensing aperture.

7. The applicator assembly of claim 1 , wherein a pivot joint is formed between the applicator bracket and the assembly support frame, and the applicator clamp rotates about an axis of the pivot joint such that the applicator assembly maintains a predetermined orientation relative to the surface.

8. An applicator assembly comprising:
an assembly support frame;
a material applicator configured to selectively dispense a treatment material on a surface;
an applicator clamp forming an interior space and having a dispensing aperture, the applicator clamp configured to support and position a dispensing end of the material applicator within the interior space;
an applicator tip inserted into the dispensing aperture formed in the applicator clamp, the applicator tip extending from the interior space to a location exterior of the applicator clamp, the applicator tip configured to receive the treatment material from the dispensing end of the material applicator;
an applicator bracket attached to the material applicator and the applicator clamp, the applicator bracket configured to slidably attach the material applicator and the applicator clamp to the assembly support frame;
an automated applicator actuator operatively attached to the assembly support frame and the applicator bracket, the automated applicator actuator configured to manipulate the applicator bracket between a first position and a second position;
an excess material aperture formed in the applicator clamp; and
a material chamber attached to an exterior surface of the applicator clamp,
wherein a pivot joint is formed between the applicator bracket and the assembly support frame, and the applicator clamp rotates about an axis of the pivot joint such that the applicator assembly maintains a predetermined orientation relative to the surface, and
wherein the pivot joint is further configured to rotate the applicator clamp between a pivot joint first position and a pivot joint second position, wherein the material chamber is aligned with the excess material aperture such that when the applicator clamp rotates from the pivot joint first position to the pivot joint second position the treatment material is emptied into the material chamber through the excess material aperture.

9. A surface treatment system for applying a treatment material to a surface, the surface treatment system comprising:
an applicator assembly configured to treat the surface with the treatment material, the applicator assembly including:
an assembly support frame;
a material applicator configured to dispense the treatment material on the surface;
an applicator clamp forming an interior space and having a dispensing aperture, the applicator clamp configured to support and position a dispensing end of the material applicator within the interior space;

an applicator tip being formed from an absorbent material and inserted into the dispensing aperture of the applicator clamp, the applicator tip including an interior portion and an exterior portion, the interior portion extending into the interior space and aligned with the material applicator such that the interior portion of the applicator tip absorbs the treatment material dispensed by the material applicator, the exterior portion extends from the dispensing aperture to an exterior position and the exterior portion applies the treatment material along a surface to be treated;
an applicator bracket attached to the material applicator and the applicator clamp, the applicator bracket configured to slidably attach the material applicator and the applicator bracket to the assembly support frame; and
an automated applicator actuator operatively attached to the assembly support frame and the applicator bracket, the automated applicator actuator configured to manipulate the applicator bracket, the material applicator and the applicator clamp between a first position and a second position;

a pressure vessel configured to hold the treatment material;
a material supply line extending from the pressure vessel to the material applicator, the material supply line configured to supply the treatment material to the material applicator, wherein, the pressure vessel is coupled to the material supply line;
a robot arm operably attached to the assembly support frame and configured to move and position the applicator assembly during treatment of the surface;
at least one sensor operatively attached to the applica
