Abstract

A laminating device and a laminating method are disclosed. The laminating device is used for laminating a flexible panel together with a curved cover plate. The curved cover plate is provided with a central area and an edge bending area located in a first direction in the central area. The laminating device comprises a movable mechanism, which is arranged opposite the curved cover plate in a second direction and comprises: a first movable base table and a second movable base table, which are arranged opposite each other in the first direction; and an elastic supporting member, which is provided with an elastic supporting portion, the elastic supporting portion covering parts of the first movable base table station and the second movable base table station that are close to the curved cover plate, and being used for fixing the flexible panel.

First claim

What is claimed is:

1. A laminating device for laminating a flexible panel and a curved cover plate, wherein the curved cover plate has a central area and an edge bending area located in a first direction of the central area, comprising:
a movable mechanism, wherein the movable mechanism is arranged opposite the curved cover plate in a second direction and comprises:
a first movable base table;
a second movable base table arranged opposite the first movable base table in the first direction; and
an elastic supporting member having an elastic supporting portion, wherein the elastic supporting portion covers on parts of the first movable base table and the second movable base table that are close to the curved cover plate, and is used for fixing the flexible panel, wherein:
the movable mechanism is adapted to move in a direction close to the curved cover plate, such that the flexible panel is laminated to the central area; and
the first movable base table and the second movable base table are adapted to move in the first direction in directions away from each other, such that the flexible panel is laminated to the edge bending area;

a carrier film comprising a laminating portion for laminating with the flexible panel and connecting portions located at opposite two sides of the laminating portion in the first direction, the laminating portion being supported on the elastic supporting portion; and
a clamping adjustment mechanism connected with the connecting portion and adapted to apply a clamping force to the connecting portion, such that the laminating portion is laminated to the elastic supporting portion;
wherein, when the first movable base table and the second movable base table move in the first direction in directions away from each other, the clamping adjustment mechanism is adapted to reduce the clamping force applied to the connecting portion,
wherein an adhesive layer for adhering to the flexible panel is provided on the laminating portion, and
wherein the first movable base table and the second movable base table comprise a supporting table covered with the elastic supporting portion and a fixing table located on the supporting table away from the elastic supporting portion, surfaces of the supporting table of the first movable base table and the supporting table of the second movable base table facing each other are provided with a sawtooth structure and engage with each other.

2. The laminating device according to claim 1 , wherein the movable mechanism further comprises:
a first fixing slide rail, wherein the first movable base table is slidably mounted on the first fixing slide rail, and the first movable base table slides relative to the first fixing slide rail in the first direction;
a second fixing slide rail, wherein the second movable base table is slidably mounted on the second fixing slide rail, and the second movable base table slides relative to the second fixing slide rail in the first direction;
a movable base, having a first pushing inclined surface cooperated with the first movable base table and a second pushing inclined surface cooperated with the second movable base table;
a first driving member, connected with the movable base, and configured to drive the movable base to move in a direction close to or away from the central area of the curved cover plate;
wherein, when the first driving member drives the movable base to move in a direction close to the central area of the curved cover plate, the first pushing inclined surface and the second pushing inclined surface respectively push the first movable base table and the second movable base table to move in the first direction in directions away from each other.

3. The laminating device according to claim 2 , wherein a reset elastic member is further provided in the first movable base table and the second movable base table, wherein,
when the first driving member drives the movable base to move in a direction close to the central area of the curved cover plate, the first movable base table and the second movable base table move in the first direction in directions away from each other, and the reset elastic member is elastically deformed;
when the first driving member drives the movable base to move in a direction away from the central area of the curved cover plate, the reset elastic member restores elastic deformation, to drive the first movable base table and the second movable base table to move in the first direction in directions close to each other.

4. The laminating device according to claim 3 , wherein:
the elastic supporting member further comprises a fixing portion extending from two ends of the elastic supporting portion to a direction close to the fixing table, the fixing portion is connected with the fixing table, such that the elastic supporting member is fixed on the first movable base table and the second movable base table.

5. The laminating device according to claim 3 , wherein the elastic supporting member is a silicone member.

6. The laminating device according to claim 2 , wherein:
the elastic supporting member further comprises a fixing portion extending from two ends of the elastic supporting portion to a direction close to the fixing table, the fixing portion is connected with the fixing table, such that the elastic supporting member is fixed on the first movable base table and the second movable base table.

7. The laminating device according to claim 2 , wherein the elastic supporting member is a silicone member.

8. The laminating device of claim 1 , wherein the movable mechanism further comprises:
a second driving member connected to the first movable base table, and configured to drive the first movable base table to move in the first direction in directions close to or away from the second movable base table; and
a third driving member connected to the second movable base table, and configured to drive the second movable base table to move in the first direction in directions close to or away from the first movable base table.

9. The laminating device according to claim 8 , wherein:
the elastic supporting member further comprises a fixing portion extending from two ends of the elastic supporting portion to a direction close to the fixing table, the fixing portion is connected with the fixing table, such that the elastic supporting member is fixed on the first movable base table and the second movable base table.

10. The laminating device according to claim 8 , wherein the elastic supporting member is a silicone member.

11. The laminating device according to claim 1 , wherein:
the elastic supporting member further comprises a fixing portion extending from two ends of the elastic supporting portion to a direction close to the fixing table, the fixing portion is connected with the fixing table, such that the elastic supporting member is fixed on the first movable base table and the second movable base table.

12. The laminating device according to claim 11 , wherein the sawtooth structure is formed by splicing a plurality of tooth parts in sequence, and shapes of the plurality of tooth parts are at least one of a rectangle and a circular arc.
