Problems solved by technology

[0003] For the existing production equipment of curved surface display screen, when the flexible film and the curved surface protection cover are bonded, the flexible film needs to be supported by a flexible carrier tape, and the flexible carrier tape needs to be adjusted multiple times by the extrusion device Make it in a tensioned state, so as to improve the flatness of the flexible film during lamination and improve the quality of the product; however, multiple adjustments make the operation complicated. Due to its own flexible material, the carrier tape may still have wrinkles after adjustment.

Abstract

The invention discloses a film pressing device for a mobile phone screen and a pasting method. The film pressing 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 extrusion claw devices are further arranged on a lower cavity; the extrusion claw devices are arranged on both sides of the lifting pressurizing part; a limiting device is arranged on an upper cavity; the limiting device is used for limiting positions of both ends of the carrying belt. By adopting the film pressing device, the flexible film is pasted to thecurved surface 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 limiting device, 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 manufacturing, in particular to a film pressing device and a bonding method for mobile phone screens. Background technique [0002] At present, curved screens have been gradually applied to smart phones. For large-screen mobile phones, curved screens are easier to operate and have better visual effects. For the increasingly popular wearable devices, curved screens are the trend and inevitable trend of development. [0003] For the existing curved display production equipment, when the flexible film is attached to the curved protective cover, the flexible film needs to be supported by a flexible carrier tape, and the flexible carrier tape needs to be adjusted multiple times by the extrusion device. Make it in a tensioned state, thereby improving the flat state of the flexible film during bonding and improving the quality of the product; however, multiple adjustments make the operation compli...
