Abstract

A protective film peeling apparatus includes a peeling tape, a tape support portion disposed under one side of the peeling tape, a first pressing portion which is disposed on the one side of the peeling and fixes the one side of the peeling tape to the tape support portion, a second pressing portion which is disposed on another side of the peeling tape and presses and attaches the another side of the peeling tape to one side of a dummy portion of a protective film on a panel, and a grip portion disposed on the dummy portion. The tape support portion and the first pressing portion peel the one side of the dummy portion and a predetermined portion of the dummy portion, and the grip portion peel a remaining portion of the dummy portion.

First claim

What is claimed is:

1. A protective film peeling apparatus comprising:
a peeling tape extending in a first direction;
a tape support portion disposed under one side of the peeling tape;
a first pressing portion which is disposed on the one side of the peeling tape, moves in a downward direction and presses and fixes the one side of the peeling tape to the tape support portion;
a second pressing portion which is disposed on another side of the peeling tape, presses the another side of the peeling tape to one side of a dummy portion of a protective film on a panel and attaches the another side of the peeling tape to the one side of the dummy portion; and
a grip portion disposed on the dummy portion,
wherein the tape support portion and the first pressing portion move in an upward direction and peel the one side of the dummy portion and a predetermined portion of the dummy portion, and
wherein the grip portion grips the peeled predetermined portion of the dummy portion and peels a remaining portion of the dummy portion.

2. The protective film peeling apparatus of claim 1 , wherein the second pressing portion moves in the upward direction after moving in the downward direction and presses and attaches the another side of the peeling tape to the one side of the dummy portion.

3. The protective film peeling apparatus of claim 2 , wherein the grip portion moves in the downward direction, thereby is disposed below the tape support portion, and grips the peeled predetermined portion of the dummy portion after the predetermined portion of the dummy portion is peeled.

4. The protective film peeling apparatus of claim 3 , wherein the first pressing portion moves in the upward direction, thereby is spaced apart from the one side of the dummy portion when the grip portion grips the peeled predetermined portion of the dummy portion.

5. The protective film peeling apparatus of claim 1 , further comprising:
a stage on which the panel is placed;
a first driving portion which moves the first pressing portion in the upward and downward directions;
a second driving portion which moves the second pressing portion in the upward and downward directions;
a third driving portion which moves the grip portion in the upward and downward directions;
a first main driving portion which moves the tape support portion, the first and second pressing portions and the grip portion in the upward and downward directions; and
a second main driving portion which reciprocates the tape support portion and the first and second pressing portions in the first direction.

6. The protective film peeling apparatus of claim 5 , wherein the first main driving portion moves the tape support portion, the first and second pressing portions and the grip portion in the upward direction when the predetermined portion of the dummy portion is peeled.

7. The protective film peeling apparatus of claim 5 , wherein the second main driving portion moves the tape support portion and the first and second pressing portions in the first direction such that the tape support portion and the first and second pressing portions move away from the grip portion, when the grip portion grips the peeled predetermined portion of the dummy portion.

8. The protective film peeling apparatus of claim 5 , wherein the stage moves in the first direction and moves away from the grip portion and the remaining portion of the dummy portion is peeled, after the grip portion grips the peeled predetermined portion of the dummy portion.

9. The protective film peeling apparatus of claim 5 , further comprising:
a fixing portion which is disposed on one side of the stage adjacent to the one side of the dummy portion and presses the protective film adjacent to the one side of the dummy portion.

10. The protective film peeling apparatus of claim 1 , wherein the dummy portion comprises:
a first dummy portion defined as the one side of the dummy portion; and
a second dummy portion extending from the first dummy portion in the first direction,
wherein the panel comprises:
a plurality of unit panels arranged in the first direction,
wherein each of the plurality of unit panels comprises:
a bending portion extending in the first direction, and
wherein the second dummy portion overlaps with the bending portion in each of the plurality of unit panels.

11. The protective film peeling apparatus of claim 10 , further comprising:
an adhesive member which is disposed between the panel and the protective film and attaches the protective film to the panel.

12. The protective film peeling apparatus of claim 11 , wherein the peeling tape comprises: a peeling adhesive which is provided on the another side of the peeling tape and attaches the another side of the peeling tape to the first dummy portion, and
wherein an adhesive strength of the peeling adhesive is stronger than an adhesive strength of the adhesive member.

13. The protective film peeling apparatus of claim 11 , further comprising:
a suction portion disposed between the first pressing portion and the second pressing portion,
wherein the suction portion is driven in the peeling of the first dummy portion and sucks carbonized particles of the adhesive member overlapping with the first dummy portion.

14. The protective film peeling apparatus of claim 10 , wherein a width of the first dummy portion in a second direction intersecting the first direction is greater than a width of the second dummy portion in the second direction, and
wherein a width of the peeling tape in the second direction is equal to or less than the width of the first dummy portion.

15. The protective film peeling apparatus of claim 1 , wherein the grip portion has an L-shape when viewed in a second direction intersecting the first direction.

16. The protective film peeling apparatus of claim 1 , wherein the grip portion comprises:
a first grip portion; and
a second grip portion spaced apart from the first grip portion,
wherein the second pressing portion moves in the downward direction and the upward direction between the first grip portion and the second grip portion, and
wherein the first and second grip portions move in the downward direction, thereby are disposed below the tape support portion, and move close closer to each other to grip the peeled predetermined portion of the dummy portion, after the predetermined portion of the dummy portion is peeled.

17. The protective film peeling apparatus of claim 16 , wherein the first grip portion comprises:
a first sub-grip portion; and
a second sub-grip portion connected to a bottom of the first sub-grip portion and having an L-shape when viewed in a second direction intersecting the first direction,
wherein the second grip portion comprises:
a third sub-grip portion; and
a fourth sub-grip portion connected to a bottom of the third sub-grip portion and having an L-shape when viewed in the second direction,
wherein the second and fourth sub-grip portions move close closer to each other and grip the peeled predetermined portion of the dummy portion.

18. The protective film peeling apparatus of claim 17 , further comprising:
anti-adhesion coating layers respectively provided on one side surface of the second sub-grip portion and one side surface of the fourth sub-grip portion which face each other.

19. The protective film peeling apparatus of claim 18 , wherein the one side surface of the second sub-grip portion and the one side surface of the fourth sub-grip portion have uneven structures.
