Abstract

A bonding device includes a first panel support, a second panel support disposed below the first panel support, a diaphragm disposed on and extending along the first panel support, the diaphragm being disposed between the first panel support and the second panel support, and a window fixing chuck disposed on the diaphragm, the window fixing chuck including a groove facing the diaphragm. A through-hole extends from the second panel support to the first panel support, and the diaphragm is disposed on the through-hole.

First claim

What is claimed is:

1. A bonding device comprising:
a first panel support;
a second panel support disposed below the first panel support;
a diaphragm disposed on and extending along the first panel support, the diaphragm being disposed between the first panel support and the second panel support; and
a window fixing chuck disposed on the diaphragm, the window fixing chuck including a groove facing the diaphragm, wherein
a through-hole extends from the second panel support to the first panel support, and
the diaphragm is disposed on the through-hole,
the through-hole is defined in a direction perpendicular to an upper end of the first panel support from a lower end of the second panel support,
wherein a thickness of the diaphragm gradually decreases from an upper end of the first panel support to a portion between the first panel support and the second panel support, and
the thickness of the diaphragm is defined as dimension between a front surface of the diaphragm facing the window fixing chuck and a back surface of the diaphragm facing the first panel support.

2. The bonding device of claim 1 , wherein
the second panel support has a plate shape and extends in a third direction intersecting a plane defined by a first direction and a second direction intersecting the first direction, the plate shape being defined by the first direction and the third direction, and
the first panel support and the groove extend in the first direction.

3. The bonding device of claim 2 , wherein the diaphragm is not disposed on side surfaces of the second panel support, the side surfaces of the second panel support are opposite to each other in the first direction and the second direction.

4. The bonding device of claim 2 , wherein the first panel support or the second panel support and the diaphragm are disposed in the groove of the window fixing chuck upon the window fixing chuck or the first panel support or the second panel support being moved in the third direction.

5. The bonding device of claim 2 , wherein
the diaphragm overlaps the first panel support, and the first panel support includes a curved surface convex in an upward direction corresponding to the third direction, and
the window fixing chuck includes a concave curved surface at an inner end of the groove of the window fixing chuck facing the curved surface of the first panel support.

6. The bonding device of claim 5 , wherein the first panel support has a maximum width greater than a width of the second panel support based on the second direction.

7. The bonding device of claim 5 , wherein the diaphragm comprises:
a first portion disposed on the curved surface of the first panel support; and
a second portion disposed between the first panel support and the second panel support.

8. The bonding device of claim 7 , wherein
the first portion of the diaphragm is disposed on the through-hole extending from the second panel support to the first panel support and expanded by air injected through the through-hole, and
the second portion of the diaphragm does not overlap the through-hole.

9. The bonding device of claim 7 , further comprising:
a fastening unit that fastens the second panel support to the first panel support and that does not overlap the through-hole.

10. The bonding device of claim 9 , wherein the fastening unit passes through the second panel support and the second portion of the diaphragm and is inserted into the first panel support.

11. The bonding device of claim 9 , wherein the fastening unit passes through the second panel support, is inserted into the first panel support, and does not pass through the second portion of the diaphragm.

12. The bonding device of claim 2 , wherein the through-hole extends from an upper end of the first panel support in the first direction.

13. The bonding device of claim 2 , wherein the first panel support has a maximum width equal to a width of the second panel support based on the second direction.
