Abstract

A device for forming a glass includes a housing member, a support member, and an intake member. The housing member includes a first part, at least one suction hole, and a plurality of sidewalls. The first part is substantially parallel to a surface defined by first and second directions. The suction hole is defined in the first part. The sidewalls extend from the first part. The support member is disposed on the first part. The support member includes a first surface configured to support the glass, a second surface overlapping and facing the first surface in a thickness direction, and a plurality of side surfaces configured to connect the first surface to the second surface. Each of first and second side surfaces of the side surfaces face each other and have a curved shape. The intake member is configured to perform an intake operation through the suction hole.

First claim

What is claimed is:

1. A device for forming glass, comprising:
a housing member comprising a first part that is substantially parallel to a surface defined by a first direction and a second direction that crosses the first direction, the housing member further comprising at least one suction hole defined in the first part, and a plurality of sidewalls extending from the first part;
a support member disposed on the first part and comprising a first surface configured to support the glass, a second surface overlapping and facing the first surface in a thickness direction, and a plurality of side surfaces each configured to connect the first surface to the second surface, wherein first and second side surfaces of the side surfaces have an entirely curved shape extending from the first surface to the second surface of the support member; and
an intake member configured to apply vacuum pressure through the suction hole.

2. The device of claim 1 , wherein a plurality of grooves are defined in the first part, and
the support member further comprises a plurality of protrusions, each protruding from the second surface and each coupled to the grooves.

3. The device of claim 2 , wherein a thickness of each of the protrusions is greater than a depth of each of the grooves in the thickness direction.

4. The device of claim 3 , wherein the second surface is spaced apart from the first part by the protrusions, and
the glass has a thickness equal to or greater than a distance between the second surface and the first part.

5. The device of claim 1 , wherein the sidewalls comprise first and second sidewalls facing each other in the first direction and respectively extending from first and second edges of the first part, and wherein
the sidewalls further comprise third and fourth sidewalls facing each other in the second direction and respectively extending from third and fourth edges of the first part.

6. The device of claim 5 , wherein at least one sidewall of the first to fourth sidewalls is attached to the other sidewalls.

7. The device of claim 5 , wherein at least a portion of each of inner surfaces of the first and second sidewalls has a curved shape.

8. The device of claim 5 , wherein the first side surface is spaced a predetermined distance from the first sidewall in the first direction, and
the second side surface is spaced by the predetermined distance from the second sidewall in the first direction.

9. The device of claim 8 , wherein a distance between the glass and the first sidewall is less than the predetermined distance in the first direction.

10. The device of claim 9 , wherein a distance between the glass and the second sidewall is less than the predetermined distance in the first direction.

11. The device of claim 1 , wherein the sidewalls comprise first and second sidewalls facing each other in the first direction and respectively extending from first and second edges of the first part, and third and fourth sidewalls facing each other in the second direction and respectively extending from third and fourth edges of the first part, and
the first part comprises at least one groove of which at least an area overlaps the suction hole, the at least one groove recessed from the first sidewall to the second sidewall in the thickness direction.

12. The device of claim 11 , wherein the second surface contacts the first part.

13. The device of claim 11 , wherein at least a portion of each of inner surfaces of the first and second sidewalls has a curved shape.

14. The device of claim 11 , wherein the first side surface is spaced a predetermined distance from the first sidewall in the first direction, and the second side surface is spaced a predetermined distance from the second sidewall in the first direction.

15. The device of claim 14 , wherein the groove has a first end closer to the first sidewall than the first side surface in the first direction, and a second end closer to the second sidewall than the second side surface in the first direction.

16. The device of claim 1 , wherein the intake member comprises:
a suction pad connected to the first part and overlapping the suction hole;
a connection tube connected to the suction pad; and
a suction unit connected to the connection tube.

17. The device of claim 1 , wherein a side surface of the glass is configured to move along a first sidewall of the plurality of sidewalls when the vacuum pressure is applied, and the side surface of the glass bends around the first side surface of the support member to the second surface of the support member.

18. The device of claim 1 , wherein the first and second side surfaces of the side surfaces have a semicircular shape.
