Apparatus of cleaning rubbing-cloth

1. An apparatus for removing particles from a rubbing-cloth for rubbing an alignment film, the apparatus comprising:

a rubbing-cloth fixing unit fixed to a base body and fixing the rubbing-cloth;

a pile removing head disposed substantially above the rubbing-cloth fixing unit, the pile removing head sucking particles disposed on the rubbing-cloth to remove the particles from the rubbing-cloth; and

a transferring unit installed with the base body, the transferring unit transferring the pile removing head along an upper surface of the rubbing-cloth,

wherein the pile removing head includes a pile floating unit,

wherein the pile floating unit includes:

an air-spraying unit spraying air to the rubbing-cloth to float the piles from the rubbing-cloth; and

an air providing unit providing air to the air spraying unit.

2. The apparatus of claim 1 , wherein the rubbing-cloth fixing unit includes:

an adsorption table having a plurality of through holes for adsorbing the rubbing-cloth;

a vacuum tube connected to the through holes; and

a vacuum generator connected to the vacuum tube and generating a substantially lower pressure than atmospheric pressure within the through holes.

3. The apparatus of claim 1 , wherein the air spraying unit has a substantially slit shape.

4. The apparatus of claim 1 , wherein the transferring unit includes:

a screw bar installed at the rubbing-cloth fixing unit and screw-coupled to a part of the pile removing head; and

a rotator rotating the screw bar to drive the pile removing head.

5. The apparatus of claim 4 , wherein the rotator is a forward/backward motor that rotates the screw bar forward/backward.

6. The apparatus of claim 1 , wherein the rubbing-cloth fixing unit comprises at least one sensor disposed on a portion corresponding to an end of the rubbing-cloth to set an operating position of the pile removing head depending on a size of the rubbing-cloth.

7. The apparatus of claim 6 , wherein the sensor is a proximity sensor that is operated when the pile removing head approaches within a predetermined range.

8. The apparatus of claim 1 , further comprising a lighting unit emitting light to the rubbing-cloth to help locate piles remaining on the rubbing-cloth.

9. The apparatus of claim 8 , wherein the lighting unit is a sodium lamp.

10. The apparatus according to claim 1 , wherein the pile removing head comprises a height adjusting unit adjusting an interval between the pile removing head and the rubbing-cloth.

11. An apparatus for removing particles from a rubbing-cloth for rubbing an alignment film, the apparatus comprising:

a rubbing-cloth fixing unit fixed to a base body and fixing the rubbing-cloth;

a pile removing head disposed substantially above the rubbing-cloth fixing unit, the pile removing head sucking particles disposed on the rubbing-cloth to remove the particles from the rubbing-cloth; and

a transferring unit installed with the base body, the transferring unit transferring the pile removing head along an upper surface of the rubbing-cloth,

wherein the pile removing head includes:

an air spraying unit spraying the air to the rubbing-cloth to float the piles from the rubbing-cloth, and an air providing unit providing air to the air spraying unit; and

a pile removing unit including a body having an opening that faces the rubbing-cloth, a suction unit mounted within the body to suck the floated piles through the opening, and a vacuum pressure generator connected to the suction unit.

12. The apparatus of claim 11 , wherein the pile removing head comprises a suction-force enhancing member that reduces an area of the opening.
