Laminating process for curved surface cover plate and flexible film

Abstract

The embodiment of the invention provides a laminating process for a curved surface cover plate and a flexible film. The process comprises the steps that the curved surface cover plate is fixed, the flexible film is arranged on a bearing film, and the two ends of the bearing film is fixed, so that the flexible film is opposite to the inner surface of the curved surface cover plate; a first roller is adopted to abut against an initial position of the middle of the bearing film, so that the middle of the flexible film and the middle of the curved surface cover plate are subjected to laminating atfirst, and then the first roller is moved towards an arc edge area of one side of the curved surface cover plate by a preset distance; a second roller is adopted to move from the initial position tothe arc edge area of the other side of the curved surface cover plate; the first roller is continued to move towards the arc edge area of one side of the curved surface cover plate, so that the flexible film and the curved surface cover plate are subjected to laminating completely; and in the whole laminating process, the two opposite ends of the bearing film are controlled to do matched movementin the direction of reducing the tensile force of the bearing film. The laminating process is suitable for laminating of flexible films on curved surface cover plates in various shapes, and the high laminating quality and high laminating efficiency are achieved even for cover plates with large curved radian.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of flexible screen lamination, and in particular to a lamination process of a curved cover plate and a flexible film. Background technique [0002] With the continuous mass production of flexible screens, the application of flexible screens will experience explosive growth in the future. Among them, how to bond the flexible screen to the protective cover glass with high efficiency and high quality, especially the curved 3D cover glass, has become the core technology and core competitiveness in the display field. [0003] At present, the existing bonding method for bonding the flexible screen to the curved cover glass is as follows: a bonding part is arranged under the flexible screen, and a deformation control part is used to push the bonding part to move upward. After the inner surface of the curved cover glass is in contact, the bonding part deforms and gradually fills the bending ar...

Problems solved by technology

In this bonding method, the shape of the bonding part has a great influence on the bonding result. When the bending arc of the cover glass becomes larger, it is difficult to ensure that the deformation of the bonding part can fill the bending area, thereby affecting the bonding quality; Moreover, this method usually needs to verify the design of multiple fitting parts, and the cost of fitting trial and error is high and the time is long
