Abstract
A bonding device for attaching a curved cover plate with an irregular shape to a flexible screen includes: a first attaching half having a first abutting wall, a second half, and a driving component. The first abutting wall includes a first curved wall and a first flat wall. The first curved wall matches with an inner surface of the arc hook area, and the first flat wall is smoothly connected to the first curved wall. The second attaching half has a second abutting wall. The second abutting wall includes a second curved wall and a second flat wall. The second curved wall matches with an inner surface of the arc hook area. The second flat wall is smoothly connected to the second curved wall. The driving component drives the first attaching half and the second attaching half to move relative to each other.
