Abstract

The present disclosure provides a box for loading a film and a method for loading a film. The box includes: a base provided with a level adjuster and a lower buffer member supported by the level adjuster. The method includes: adjusting the level adjuster such that a levelness of the lower buffer member is within an allowable range; and loading the film on the lower buffer member after adjusting the level adjuster.

First claim

What is claimed is:

1. A box for loading a protective film used in a process of manufacturing a flexible organic light emitting diode display panel, comprising:
a base provided with a level adjuster;
a lower buffer member supported by the level adjuster;
a protective cover for use with the base, the protective cover comprising a top part; and
an upper buffer member between the protective cover and the lower buffer member, the upper buffer member comprising a first buffer member close to the top part, a second buffer member far from the top part, and a third buffer member between the first buffer member and the second buffer member,
wherein the level adjuster comprises a plurality of adjusting members, which pass through the base and support the lower buffer member, and the plurality of adjusting members are connected to the lower buffer member and not connected to the upper buffer member.

2. The box for loading a film according to claim 1 , wherein
at least part of the plurality of adjusting members are connected to the lower buffer member.

3. The box for loading a film according to claim 1 , wherein
at least one of the plurality of adjusting members comprises a screw member.

4. The box for loading a film according to claim 1 , wherein
the third buffer member comprises at least one elastic member, which is connected to the first buffer member and the second buffer member.

5. The box for loading a film according to claim 4 , wherein
the at least one elastic member comprises a plurality of elastic members, which are uniformly distributed between the first buffer member and the second buffer member.

6. The box for loading a film according to claim 1 , further comprising:
an operating member through the top part of the protective cover, wherein one end of the operating member is in contact with the upper buffer member.

7. The box for loading a film according to claim 6 , wherein
the operating member is at a central position of the top part.

8. The box for loading a film according to claim 6 , wherein
the operating member comprises a rotary knob.

9. The box for loading a film according to claim 1 , further comprising:
at least one fixed stopper and at least one movable stopper which are on the base and around the lower buffer member.

10. The box for loading a film according to claim 9 , wherein
the at least one fixed stopper comprises a plurality of fixed stoppers, wherein a part of the plurality of fixed stoppers are on a first side of an edge of the lower buffer member, and another part of the plurality of fixed stoppers are on a second side of the edge of the lower buffer member, the first side being adjacent to the second side;
the at least one movable stopper comprises a plurality of movable stoppers, wherein a part of the plurality of movable stoppers are on a third side of the edge of the lower buffer member, the third side being opposite to the first side, and another part of the plurality of movable stoppers are on a fourth side of the edge of the lower buffer member, the fourth side being opposite to the second side.

11. A method for loading a film using a box for loading a protective film used in a process of manufacturing a flexible organic light emitting diode display panel, which comprises a base provided with a level adjuster, and a lower buffer member supported by the level adjuster, a protective cover for use with the base, the protective cover comprising a top part, and an upper buffer member between the protective cover and the lower buffer member, the upper buffer member comprising a first buffer member close to the top part, a second buffer member far from the top part, and a third buffer member between the first buffer member and the second buffer member, wherein the level adjuster comprises a plurality of adjusting members, which pass through the base and support the lower buffer member, and the plurality of adjusting members are connected to the lower buffer member and not connected to the upper buffer member, comprising:
adjusting the level adjuster such that a levelness of the lower buffer member is within an allowable range, the allowable range is [−5°, 5°]; and
loading the film on the lower buffer member after adjusting the level adjuster.

12. The method according to claim 11 , wherein
the box further comprises an operating member through a top part of the protective cover, wherein one end of the operating member is in contact with the upper buffer member;
the method further comprising:
butt jointing the protective cover with the base after loading the film on the lower buffer member; and
adjusting the operating member to adjust a positional relationship between the upper buffer member and the film, such that the upper buffer member is in contact with the film.

13. The method according to claim 11 , wherein
the box further comprises at least one fixed stopper and at least one movable stopper which are on the base, wherein the at least one fixed stopper and the at least one movable stopper are around the lower buffer member;
wherein loading the film on the lower buffer member comprises:
adjusting a position of the at least one movable stopper to a maximum gap position, wherein the maximum gap position is a position of the at least one movable stopper in a case where a gap distance between the at least one movable stopper and a fixed stopper opposite to the at least one movable stopper is maximum;
loading the film with a position of the at least one fixed stopper as a reference position, such that an edge of the film is in contact with the at least one fixed stopper; and
adjusting a position of the at least one movable stopper such that the at least one movable stopper is in contact with the edge of the film, after the edge of the film being in contact with the at least one fixed stopper.
