Bonding devices and bonding methods for curved cover plates with irregular shape and flexible screen

A bonding device for attaching a curved cover plate with an irregular shape to a flexible screen, the curved cover plate comprising a flat area and a pair of arc hook areas extending from the flat area and located on opposite sides of the flat area, the device comprising:

• a first attaching half having a first abutting wall formed on a periphery thereof, the first abutting wall comprises a first curved wall and a first flat wall, the first curved wall matching with a shape of an inner surface of the arc hook area on one side of the curved cover plate, and the first flat wall being smoothly connected to the first curved wall;
• a second attaching half having a second abutting wall formed on a periphery thereof, the second abutting wall comprising a second curved wall and a second flat wall, the second curved wall matching with a shape of an inner surface of the arc hook area on another side of the curved cover plate, and the second flat wall being smoothly connected to the second curved wall,
• wherein the first attaching half and the second attaching half have a closed position where the first flat wall abuts against the second flat wall on a same plane, and an open position where the first flat wall and the second flat wall are separated from each other, in the closed position, the first flat wall and the second flat wall abut a middle portion of the flexible screen onto an inner surface of the flat area of the curved cover plate, in the open position, the first curved wall and the second curved wall abut edges of the flexible screen onto the inner surfaces of the arc hook areas of the curved cover plate;
• and
• a driving component driving the first attaching half and the second attaching half to move relative to each other, to switch the first attaching half and the second attaching half between the closed position and the open position.
