Abstract

A film peeling device for peeling a film from a substrate including a transfer module configured to transfer the substrate that is arranged in a vertical direction with respect to a bottom surface of the substrate, and a peeling module configured to peel the film from the substrate transferred by the transfer module.

First claim

What is claimed is:

1. A film peeling device for peeling a film from a substrate, the film peeling device comprising:
a transfer module configured to transfer a substrate that is arranged in a vertical direction from a front side of the transfer module to a rear side of the transfer module in a substrate transfer direction;
a peeling module configured to peel a film from the substrate transferred by the transfer module; and
a first roller comprising a porous peeling roller configured to provide an absorption force for peeling the film from the substrate,
wherein the peeling module comprises:
a film gripper fixable to an end of the film; and
a film gripper guide configured to guide the film gripper having the film fixed thereto away from the first roller film along the film gripper guide.

2. The film peeling device of claim 1 , wherein the transfer module comprises:
a front substrate transfer unit at a front side of the peeling module and configured to shift the substrate from the front side of the transfer module to the peeling module; and
a rear substrate transfer unit at a rear side of the peeling module and configured to shift the substrate peeled by the peeling module from the peeling module to the rear side of the transfer module.

3. The film peeling device of claim 2 , wherein each of the front substrate transfer unit and the rear substrate transfer unit comprises;
an extending guide extended in a substrate transfer direction;
a substrate gripper installed on the extending guide, shiftable along the extending guide, and fixable to a side of the substrate; and
a first, drive motor configured to shift the substrate gripper along the extending guide.

4. The film peeling device of claim 3 , wherein the extending guide, the substrate gripper, and the first drive motor of each of the front substrate transfer unit and the rear substrate transfer unit are arranged at an upper region of the transfer module, and wherein each of the front substrate transfer unit and the rear substrate transfer unit further comprises another extending guide, another substrate gripper, and another first driver motor arranged at a lower region of the transfer module.

5. The film peeling device of claim 3 , wherein the extending guides of the front substrate transfer unit and the rear substrate transfer unit are separated from each other.

6. The film peeling device of claim 3 , wherein the extending guides of the front substrate transfer unit are integrally formed with the extending guides of the rear substrate transfer unit.

7. The that peeling device of claim 3 , further comprising a vacuum chuck module for maintaining the substrate to stand in the vertical direction, wherein the vacuum chuck module comprises,
a frame;
a substrate support including, an absorbing hole for providing an air absorbing pressure to the substrate, the substrate support being installed on the frame along the extending guide; and
a second drive motor configured to generate power for providing the air absorbing pressure through the absorbing hole.

8. The film peeling device of claim 2 , wherein the peeling module comprises a first peeler and a second peeler at respective sides of the transfer module,
wherein the first peeler is configured to peel the film from the substrate and comprises:
the film gripper fixable to the end of the film;
the film gripper guide installed to allow the film gripper to shift along the film gripper guide;
a guide support supporting the film gripper guide; and
a peeling module drive motor configured to generate power for shifting the film gripper along the film gripper guide, and

wherein the second peeler is configured to peel another film from the substrate and comprises:
another film gripper fixable to an end of the another film;
another film gripper guide installed to allow the another film gripper to shift along the another film gripper guide;
another guide support supporting the another film gripper guide; and
another peeling module drive motor configured to generate power for shifting the another film gripper along the another film gripper guide.

9. The film peeling device of claim 8 , wherein the film gripper and the guide support are extended in a direction that is perpendicular to the substrate transfer direction.

10. The film peeling device of claim 8 , wherein the peeling module is arranged between the front substrate transfer unit and the rear substrate transfer unit.

11. The film peeling device of claim 10 , wherein, the first roller is between the front substrate transfer unit and the rear substrate transfer unit and arranged between the first peeler and the second peeler, and
wherein the film peeling device further comprises a side roller at a side of the first roller toward the rear side of the transfer module,

12. The film peeling device of claim 11 , wherein the first roller is configured to absorb one side of the film, and the side roller is configured to pressurize both ends of another side of the film.

13. The film peeling device of claim 12 , wherein, while the substrate shifts to the rear substrate transfer unit from the from substrate transfer unit, the film is peeled from the substrate.

14. The film peeling device of claim 12 , further comprising:
a second roller arranged between the first roller and the second peeler; and
a nip roller at a side of the second roller toward the rear side of the transfer modulo, and pressurized in a direction toward the second roller.

15. The film peeling device of claim 12 , wherein the side roller is configured to not contact a center portion of the another side of the film between the ends when pressurizing both ends.

16. The film peeling device of claim 1 ,
wherein the film peeling device is configured to peel:
a top film attached to one side of the substrate; and
a bottom film attached to another side of the substrate, and

wherein an organic material layer is between the top film and the substrate.
