Abstract

The present disclosure provides a vacuum ring for removing bubbles of a laminated assembly and a method for bonding the laminated assembly using the same. The vacuum ring includes an indented portion receiving a laminated assembly to be sealed, and an inner space of the indented portion is in communication with a vacuum source to remove the bubbles. The vacuum ring also includes projection members that are projected inside on the bottom of the indented portion at positions where the projection members are spaced upward from a lower end of the indented portion to receive the laminated assembly, and the projections members are spaced downward from the upper end of the indented portion. Further, the laminated assembly is produced by using the vacuum ring to achieve effective exhaustion by using an aperture formed between side ends of the projection members and the bonding cover.

First claim

What is claimed is:

1. A vacuum ring comprising an indented portion formed inside the vacuum ring, a laminated assembly inserted into an inner space formed by upper and lower ends of the indented portion, and the inner space of the indented portion being in communication with a vacuum source to remove bubbles which are present between the indented portion and the laminated assembly,
wherein the vacuum ring further comprises:
a plurality of projection members that are positioned inside the indented portion along a bottom of the indented portion with intervals,
wherein the projection members are spaced upward from the lower end of the indented portion by a predetermined distance corresponding to the thickness of the laminated assembly, and the projection members are spaced apart downward from the upper end of the indented portion by a predetermined distance.

2. The vacuum ring according to claim 1 , wherein the predetermined distance between the projection members and the upper end corresponds to a thickness of a bonding cover arranged on the laminated assembly.

3. The vacuum ring according to claim 1 , wherein sides of the respective projection members have a size to form an empty aperture which is in communication with an empty space between the bottom of the indented portion and an end of the laminated assembly, and between bonding covers and the projection members.

4. The vacuum ring according to claim 3 , wherein the projection members are integrated with the bottom of the indented portion of the vacuum ring.

5. The vacuum ring according to claim 3 , wherein the projection members are selected from a quadrangular pole or a rectangular plate member.

6. The vacuum ring according to claim 5 , wherein an upper side of each projection member is larger than a lower side of the projection member so that the aperture is enlarged between the side of the projection member and the bonding covers deployed on the projection members.

7. The vacuum ring according to claim 3 , wherein the projection members are assembled to grooves formed on the bottom of the indented portion of the vacuum ring.
