Abstract

The invention discloses a lamination device for a mobile phone screen and a pasting method. The lamination device comprises a holding platform, a curved surface protection cover plate, a flexible film, a carrying belt and a lifting pressurizing part, wherein the holding platform is used for holding the curved surface protection cover plate; the flexible film is placed on the carrying belt; the carrying belt is of an elastic and soft tabulate structure; the carrying belt is placed on the lifting pressurizing part; the flexible film and the curved surface protection cover plate are correspondingly arranged up and down; a pair of clamping claw devices are further arranged on a lower cavity; the clamping claw devices are arranged on both sides of the lifting pressurizing part; a limiting device is arranged on an upper cavity; and the limiting device is used for limiting positions of both ends of the carrying belt. By adopting the lamination device, the flexible film is pasted to the curvedsurface protection cover plate with an included angle bent edge, and bubbles, wrinkles and other defects can be prevented in the pasting process of the flexible film; under the action of the limitingdevice, prior contact between an end part of the flexible film with a curved surface edge position of the curved surface protection cover plate is avoided, and defective products can be reduced.

Description

technical field [0001] The invention relates to the technical field of mobile phone screen production, in particular to a lamination device and a bonding method for mobile phone screens. Background technique [0002] The liquid crystal display technology industry has entered a mature stage. Flexible OLED (Organic Light-Emitting Diode, organic light-emitting diode) display is a new growth point for the future display industry. The flexible characteristics of flexible OLED displays are constantly being developed and utilized. Attached to a curved glass cover for front and side display of the product. [0003] For the existing production equipment of liquid crystal display screens on mobile phones, when the flexible film and the curved surface protection cover are laminated, it is generally a flat pressing operation, which is prone to defects such as bubbles and wrinkles, thereby affecting the production of curved display screens. [0004] In view of the above defects, the inv...
