Problems solved by technology

However, limited by the manufacturing technology of curved glass, for curved surfaces with a bending angle close to 90 degrees or a buckle-shaped curved surface, defects such as wrinkles, bubbles, and warping will appear between the decorative film and the curved glass at the corners of the four corners during lamination. phenomenon, it is difficult to achieve a good fit between the decorative film and the curved glass

Embodiment Construction

[0028] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0029] The invention provides a bonding process of a curved glass screen and a decorative film, which is characterized in that it comprises the following steps:

[0030] S1: Machine lamination, specifically including the following steps:

[0031] S11: Fix the curved glass in the copy mold

[0032] S12: Fix the decorative film on the heating plate of the lower chamber, place it in the airtight lower chamber,

[0033] S13: The upper chamber and the lower chamber are closed in alignment by the CCD, the heating platform is heated to release the pressure and temperature, and the flat area of ​​the decorative film and the glass is partially cured by pressing the pressure head.

[0034] S14: Vacuum the...

Abstract

The invention provides a curved glass screen and decorative film laminating process which is characterized by comprising the following steps of S1, machine table laminating and S2, water bath heating. The curved glass screen and decorative film laminating process and jig have the advantages that the yield is high, the product quality can be effectively improved, and the production cost is reduced; compared with OCA (optical clear adhesive), the hot melt adhesive is flat in surface, good in uniformity, high in hardness, high in viscosity and not prone to deformation and rebound during pressing, the problems of wrinkles, bubbles, upwarping and the like can be effectively avoided, and therefore the hot melt adhesive has great economic value and practical value.

Description

technical field [0001] The invention relates to the technical field of processing and design of curved glass screens, in particular to a bonding process and jig for curved glass screens and decorative films. Background technique [0002] With the ever-changing design of display terminals in the smart consumer electronics industry, the flat screen of mobile phones can no longer meet the diverse needs of consumers. Designing the front cover or back cover of mobile phones into a curved surface has gradually become a hot spot in the design of mobile terminals. The curved glass cover can better fit the user's hand, improving the comfort of grip and control. When the curved surface design is applied to the display, the displayed content is more three-dimensional, which improves the visual perception. At the same time, in order to increase the rich and varied appearance aesthetics and the anti-corrosion ability of curved glass, most products will attach a layer of decorative film ...
