Embodiment Construction

[0034] The present invention provides a 3D curved glass hot-pressing method. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 As shown, the present invention provides a kind of 3D curved surface glass hot pressing method, and it comprises steps as follows:

[0036] S100. The feeding device delivers the mold containing the single flat glass blank to the forming chamber after the single flat glass blank is placed in the mould.

[0037] S200. The preheating device installed vertically through the forming chamber is used in the forming chamber to preheat the mold with a built-in single piece of flat glass blank conveyed by t...

Abstract

The invention discloses a hot pressing method of 3D (three-dimensional) curved glass. The hot pressing method sequentially comprises the following steps of using a material feeding device to feed the material into a forming chamber, using a preheating device to perform multi-stage gradual temperature-rising preheating on a single plane glass blank in a die, using a hot pressing device to press the preheated single plane glass blank, and using a cooling device to perform multi-stage gradual temperature-reduction cooling on the hot-pressing formed 3D curved glass product of a smart phone. The hot pressing method has the advantages that the operation is simple, and the size of processed arc fillet can be automatically adjusted by the die; the problem of limitation to the size of processed arc fillet of the 3D curved glass by the cold pressing type in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of hot pressing methods, in particular to a hot pressing method for 3D curved glass. Background technique [0002] With the development of smartphones, in addition to Samsung and LG launching smartphones with curved screens, smartphones like Apple’s use more non-planar glass with rounded edges, that is, the middle area of ​​the glass is flat and the edges are flat. A curved surface is used for the transition, and the above-mentioned non-planar glasses all belong to the scope and application scope of the smart phone 3D curved glass of the present invention. [0003] Because the processing of 3D curved glass is difficult and the process route is relatively complicated, the existing non-flat glass generally adopts cold processing, that is, the edge of flat glass is ground and polished to obtain the required curved edge; however, The size of the arc fillet that can be processed by cold working is also limited. ...
