Abstract

An apparatus for manufacturing a glass article includes a plurality of side portions spaced apart from each other; and a plurality of heat supply portions disposed on each of the side portions; where the side portions adjacent to each other are disposed to face each other, and a glass is allowed to be disposed between the adjacent side portions.

First claim

What is claimed is:

1. An apparatus for manufacturing a glass article, the apparatus comprising:
a plurality of side portions spaced apart from each other;
a support portion which supports the side portions; and
a plurality of heat supply portions disposed on each of the side portions,
wherein the side portions include a side portion disposed between outermost side portions,
the plurality of heat supply portions are disposed directly on both of opposing surfaces of the side portion disposed between the outermost side portions,
adjacent side portions adjacent to each other are disposed to face each other,
each of the side portions includes a thermally conductive material,
the thermally conductive material of each of the side portions overlaps the heat supply portions in a thickness direction of the side portions,
a groove is defined by a depressed portion of the support portion from a surface of the support portion between the adjacent side portions, and
a glass is allowed to be inserted into the groove between the adjacent side portions.

2. The apparatus of claim 1 , wherein a heating rate thereof is about 40 K/min or greater.

3. The apparatus of claim 2 , wherein the heating rate is variable.

4. The apparatus of claim 2 , wherein each of the heat supply portions has a size of about 2 cm 2 or greater and includes a halogen lamp.

5. The apparatus of claim 1 , wherein
the heat supply portions on one of the side portions are arranged in a matrix form in a first direction and a second direction intersecting the first direction.

6. The apparatus of claim 5 , wherein
the thermally conductive material has a thermal conductivity of about 200 W/mk or greater, and
the thermally conductive material includes aluminum or a graphene.

7. The apparatus of claim 6 , wherein each of the side portions includes a first side portion, and a second side portion disposed between the first side portion and the heat supply portions thereon.

8. The apparatus of claim 7 , wherein in a plan view, the first side portion and the second side portion have a same size as each other.

9. The apparatus of claim 7 , wherein the second side portion includes the thermally conductive material.

10. The apparatus of claim 9 , wherein
the second side portion includes a plurality of side patterns, each having a linear shape extending in the first direction,
adjacent side patterns adjacent to each other are spaced apart from each other in the second direction, and
the side patterns are disposed to overlap the heat supply portions.

11. The apparatus of claim 10 , wherein the heat supply portions disposed on one of the side patterns and the heat supply portions disposed on another one of the side patterns operate independently of each other.

12. The apparatus of claim 10 , wherein the second side portion further includes a connection portion connecting the adjacent side patterns spaced apart from each other in the second direction to each other.

13. The apparatus of claim 5 , wherein
the side portions are regularly arranged with a same separation distance therebetween, and
a separation distance between the adjacent side portions is in a range of about 1 cm to about 2 cm.

14. The apparatus of claim 5 , wherein a separation distance between the groove and one of the adjacent side portions is equal to a separation distance between the groove and the other of the adjacent side portions.

15. The apparatus of claim 14 , further comprising:
a fixing portion which fixes the glass disposed between the adjacent side portions.
