Abstract

A glass manufacturing apparatus includes a support configured to hold a glass including a first flat portion, a second flat portion, and a curved portion connecting one side of the first flat portion and one side of the second flat portion. The support includes a first flat surface supporting the first flat portion, a second flat surface facing the first flat surface and supporting the second flat portion, and a curved surface connecting the flat surface to the second flat surface and supporting the curved portion.

First claim

What is claimed is:

1. A glass manufacturing apparatus, comprising:
a support configured to hold a glass including a first flat portion, a second flat portion, and a curved portion connecting the first flat portion to the second flat portion; and
a polishing pad configured to move in at least one direction,
wherein the support includes a first flat surface supporting the first flat portion, a second flat surface facing the first flat surface and supporting the second flat portion, and a curved surface connecting the first flat surface to the second flat surface and supporting the curved portion, wherein the support includes a base and a plurality of protrusions protruding from the base, and a distance between the plurality of protrusions is greater than a thickness of the polishing pad.

2. The glass manufacturing apparatus of claim 1 , wherein each of a length from one side of the first flat surface to an end of the first flat surface and a length from one side of the second flat surface to an end of the second flat surface is 2 times or more a length between the first flat surface and the second flat surface.

3. The glass manufacturing apparatus of claim 1 , wherein the support includes a vacuum hole located in at least one of the first flat surface, the second flat surface, and the curved surface.

4. The glass manufacturing apparatus of claim 1 , wherein the polishing pad moves and rotates in accordance with a shape of the curved portion of the glass so as to polish one convex side surface of the curved portion.

5. The glass manufacturing apparatus of claim 1 , wherein the distance between the plurality of protrusions is greater than a radius of the polishing pad.

6. The glass manufacturing apparatus of claim 1 , wherein the glass includes an inner surface facing a space at least partially surrounded by the first flat portion, the second flat portion, and the curved portion, and wherein the first flat portion, the second flat portion, and the curved portion support the inner surface of the glass.

7. The glass manufacturing apparatus of claim 6 , wherein the inner surface of the glass is disposed at the curved portion of the glass and has a concave shape, and wherein the curved surface of the support has a convex shape.

8. A glass manufacturing apparatus, comprising:
a jig configured to be at least partially inserted into a glass including a first flat portion, a second flat portion, and a curved portion connecting the first flat portion to the second flat portion;
a polishing pad configured to move in at least one direction; and
a stage disposed under the polishing pad and including an upper surface facing the polishing pad and a receiving groove disposed on the upper surface,
wherein the jig includes a first flat surface supporting the first flat portion, a second flat surface facing the first flat surface and supporting the second flat portion, and a curved surface connecting the first flat surface to the second flat surface and supporting the curved portion.

9. The glass manufacturing apparatus of claim 8 , wherein the jig further includes an adsorption member disposed on the first flat surface, the second flat surface, and the curved surface.

10. The glass manufacturing apparatus of claim 8 , wherein the jig includes a vacuum hole provided in at least one of the first flat surface, the second flat surface, and the curved surface.

11. A glass manufacturing apparatus, comprising:
a jig configured to be at least partially inserted into a glass including a first flat portion, a second flat portion, and a curved portion connecting the first flat portion to the second flat portion,
wherein the jig includes a first flat surface supporting the first flat portion, a second flat surface facing the first flat surface and supporting the second flat portion, and a curved surface connecting the first flat surface to the second flat surface and supporting the curved portion, and
wherein the jig further includes at least one side surface disposed between the first flat surface and the second flat surface, and an air inlet disposed on the at least one side surface.

12. The glass manufacturing apparatus of claim 8 , wherein the jig further includes at least one side surface disposed between the first flat surface and the second flat surface, and a handle portion disposed on the at least one side surface.

13. The glass manufacturing apparatus of claim 12 , wherein a thickness of the handle portion is smaller than a thickness of the jig.

14. The glass manufacturing apparatus of claim 8 , wherein the receiving groove includes a first groove for receiving one side of the glass into which the jig is inserted, and a second groove connected to the first groove and having a smaller size than the first groove.

15. The glass manufacturing apparatus of claim 8 , wherein the glass includes an inner surface facing a space at least partially surrounded by the first flat portion, the second flat portion, and the curved portion, and wherein the first flat portion, the second flat portion, and the curved portion support the inner surface of the glass.

16. The glass manufacturing apparatus of claim 15 , wherein the inner surface of the glass is disposed at the curved portion of the glass, has a concave shape, and the curved surface has a convex shape.
