Abstract

An apparatus for manufacturing a display apparatus includes: a polisher at which a polishing material is supplied to a base member of the display apparatus and the base member is polished with the polishing material to provide a polished base member having a polished surface; a conveyer to which the polished base member is provided from the polisher and from which the polished base member is transferred to outside the apparatus; and a suction unit corresponding to the conveyer and by which a pressure around the conveyer is provided to be lower than a pressure at remaining portions of the apparatus.

First claim

What is claimed is:

1. An apparatus for manufacturing a display apparatus, the apparatus comprising:
a polisher at which a polishing material comprising a liquid is supplied to a base member of the display apparatus and the base member is polished with the polishing material to provide a polished base member having a polished surface;
a conveyer to which the polished base member is provided from the polisher and from which the polished base member is transferred to outside the apparatus; and
a suction unit which faces the conveyer,
wherein
the polished base member provided to the conveyer comprises:
the polished surface facing the suction unit, and
a portion of the polishing material which remains on the polished surface of the polished base member to define a remaining polishing material on the polished base member, and

operation of the suction unit relative to the polished surface facing the suction unit provides a pressure between the polished surface and the suction unit, the pressure maintaining a level of the liquid in the remaining polishing material of the polished base member relative to a total weight of the remaining polishing material on the polished base member.

2. The apparatus of claim 1 , further comprising a feeder with which the base member is transferred to the polisher,
wherein at least one of the feeder and the conveyer comprises a roller with which the base member is movable along the apparatus.

3. The apparatus of claim 1 , wherein the operation of the suction unit further provides the pressure between the suction unit and a portion of the polisher which directly precedes the conveyor.

4. The apparatus of claim 1 , wherein the pressure between the polished surface and the suction unit maintains the level of the liquid in the remaining polishing material which is equal to or greater than about 90% of the total weight of the remaining polishing material on the polished base member.

5. The apparatus of claim 1 , further comprising a polishing head corresponding to the polisher and with which the base member is polished at the polisher to provide the polished base member having the polished surface;
wherein
the polisher comprises a belt with which the base member is movable along the apparatus to be disposed corresponding to the polishing head, and
the operation of the suction unit further provides the pressure between the suction unit and a portion of the belt which directly precedes the conveyor.

6. The apparatus of claim 1 , wherein the suction unit comprises:
a suction pipe spaced apart from and facing the conveyer and into which a gas at the conveyer is drawn,
the suction pipe comprising an inlet portion through which the gas at the conveyer is drawn into to the suction pipe, the inlet portion spaced apart from and facing the conveyer to define a space which is between the polished surface and the suction unit and extends along the conveyor from the polished base member in a direction towards the polisher; and
a guide pipe connected to the suction pipe.

7. The apparatus of claim 6 , wherein a cross-sectional area defined by the inlet portion of the suction pipe is greater than a cross-sectional area of the guide pipe.

8. The apparatus of claim 6 , wherein
the inlet portion of the suction pipe corresponds to the conveyer and a portion of the polisher which directly precedes the conveyor, and
the operation of the suction unit provides the pressure between the inlet portion of the suction unit and the polished surface and between the inlet portion of the suction unit and the portion of the polisher which directly precedes the conveyor.

9. The apparatus of claim 6 , wherein a wall of the suction pipe at the inlet portion thereof is inclined.
