Abstract

A laminating apparatus for laminating an adhesive film on a bent or curved cover window includes a rotation shaft extending in a first direction, a first frame configured to support the cover window, and including a first plate and a second plate facing each other to define an angle therebetween, and a curved connection portion between the first plate and the second plate, and a roller portion above the first frame, extending in the first direction, and configured to move in a second direction that is perpendicular to the first direction, wherein the first frame is configured to rotate with respect to the rotation shaft according to movement of the roller portion to bond the adhesive film to the cover window.

First claim

What is claimed is:

1 . A laminating apparatus for laminating an adhesive film on a bent or curved cover window, the laminating apparatus comprising:
a rotation shaft extending in a first direction; a first frame configured to support the cover window, and comprising:
a first plate and a second plate facing each other to define an angle therebetween; and
a curved connection portion between the first plate and the second plate; and
a roller portion above the first frame, extending in the first direction, and configured to move in a second direction that is perpendicular to the first direction, wherein the first frame is configured to rotate with respect to the rotation shaft according to movement of the roller portion to bond the adhesive film to the cover window.

2 . The laminating apparatus of claim 1 , further comprising a second frame extending along the second direction, and comprising first and second guide portions spaced apart from each other,
wherein the first frame is between the first and second guide portions, and wherein the first and second guide portions are configured to guide a moving direction of the roller portion.

3 . The laminating apparatus of claim 1 , further comprising a driver for generating a driving force for rotating the first frame about the rotation shaft.

4 . The laminating apparatus of claim 3 , further comprising:
a displacement sensor configured to sense a moving displacement of the roller portion; and a controller configured to receive from the displacement sensor a displacement signal corresponding to the moving displacement, and configured to control driving of the driver.

5 . The laminating apparatus of claim 4 , wherein, when the roller portion faces the connection portion, the controller is configured to transmit a driving signal for rotating the first frame about the rotation shaft to the driver.

6 . The laminating apparatus of claim 1 , wherein the angle between the first plate and the second plate is equal to, or greater than, about 0 degrees, and less than about 180 degrees.

7 . The laminating apparatus of claim 1 , wherein the adhesive film comprises a pressure sensitive adhesive.

8 . The laminating apparatus of claim 1 , further comprising a plasma discharger attached to the roller portion.

9 . A method of laminating an adhesive film on a curved or bent cover window by using a laminating apparatus, the method comprising:
seating the cover window on a first plate of a first frame; seating a portion of the adhesive film above the first plate of the first frame; moving a roller portion along an upper portion of the first plate; rotating the first frame about a rotation shaft; and moving the roller portion along an upper portion of a second plate of the first frame.

10 . The method of claim 9 , further comprising:
sensing a moving displacement of the roller portion; generating a driving signal when the roller portion faces a connection portion of the first frame between the first plate and the second plate; and generating a driving force for rotating the first frame about the rotation shaft in response to the driving signal.

11 . The method of claim 9 , wherein an angle between the first plate and the second plate is equal to, or greater than, about 0 degrees, and less than about 180 degrees.

12 . The method of claim 9 , further comprising guiding a moving direction of the roller portion by first and second guide portions that are spaced from each other, and that extend along a second direction that is perpendicular to a first direction along which the rotation shaft extends.
