Fig. 2 is the structural representation of the manufacturing installation of the face glass that provides of the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In an embodiment of the present invention, earlier to softening through the glass material of opening material, cleaning, and by adopting hot press forming technology to make the remollescent glass material become the face glass of desired shape, and face glass is carried out anneal, thus the manufacturing process of face glass simplified.
Fig. 1 shows the flow process of the manufacture method of the face glass that the embodiment of the invention provides, and details are as follows:
In step S101, glass material is opened material, cleaning.
In step S102, the glass material that this process is opened material, clean softening processing of heating up.As embodiments of the invention, can adopt heating unit to heat up and soften processing, and set different temperature, and can control heat-processed by the design temperature curve according to the material of glass raw material, make glass material reach the remollescent purpose.
In step S103, this glass material that is in soft state is carried out mold pressing thermal treatment, make this remollescent glass material become the face glass of desired shape.As embodiments of the invention, when glass material is in soft state, but adopt the heating and mould pressing mechanism to carry out the heat treated course of processing of mold pressing.But the type of heating that is somebody's turn to do the heating and mould pressing mechanism can be for heating or indirect heating certainly.In the heat treated process of mold pressing, at face glass shape demand, but the different mould structures of this heating and mould pressing mechanism are set, for example curved surface, step etc.
In step S104, to carrying out anneal through the heat treated face glass of mold pressing.
After the annealed processing, just obtained the face glass of moulding,, after anneal, still can carry out repeatedly conventional glass cold working or adopt the technology of the embodiment of the invention to carry out repeatedly heat treatment process as embodiments of the invention.In addition, can also carry out other art breading, for example tempering, silk-screen, plated film etc.
The manufacture method that the embodiment of the invention provides can be used to make the face glass of the display screen of electronics.This electronics comprises mobile telephone, MP3, MP4 etc.
The manufacture method that the embodiment of the invention provides can make polymorphic structure once-formings such as the various step of face glass, various curved surface, hole, nest, groove, bevelling, thereby simplification moulding process,, die forming softening, annealed flow process through glass material, can continuous production, greatly improved the shaping automation degree of face glass, thermoforming simultaneously can also improve the stress characteristics of glass greatly, and simultaneously heat-treating profiled have better surface smoothness than traditional cold machine-shaping.
Fig. 2 shows the structure of the producing apparatus of the face glass that the embodiment of the invention provides, and with reference to figure 2, this producing apparatus comprises three technical modules: softening process device 21, mold pressing thermal formation apparatus 22 and annealing process device 23.
Softening process device 21, the mode that adopts heating makes glass material be in the setting technological temperature to softening through the glass material of opening material, clean.Wherein, this setting technological temperature can artificially be set according to the concrete material of glass material, and the temperature curve of heating also can be set according to the temperature of material and needs.Mold pressing thermal formation apparatus 22 carries out mold pressing thermal treatment to this glass material that is in soft state, makes this remollescent glass material become the face glass of desired shape.As embodiments of the invention, but mold pressing thermal formation apparatus 22 can be the heating and mould pressing mechanism, but and with the supporting hot pressing dies that have one or more and product to be complementary of this heating and mould pressing mechanism.Annealing process device 23 carries out anneal according to the annealing parameter of setting to the face glass of compression molding, thereby the face glass of acquisition is had and the corresponding physical and chemical performance of this annealing parameter.
In order to produce the face glass of desired shape, can be according to the needed shape of face glass, but the hot pressing die that matches with the heating and mould pressing mechanism is adjusted or disposed.As embodiments of the invention, hot pressing die can comprise structures such as various step, various curved surface, hole, nest, groove, bevelling.
In sum, soften by the glass material of process being opened material, cleaning, and adopt hot press forming technology to make the remollescent glass material become the face glass of desired shape.The manufacture method that the embodiment of the invention provides can make polymorphic structure once-formings such as the various step of face glass, various curved surface, hole, nest, groove, bevelling, thereby simplifies moulding process.And thermoforming can also improve the stress characteristics of glass greatly, and heat-treating profiled shaping than traditional cold has better surface smoothness simultaneously.After the thermoforming, the face glass of moulding also can carry out mechanical cold working, and consumptive material is comparatively saved in its course of processing, especially the required rare earth material polishing powder of prior art polishing, diamond etc.Like this, embodiments of the invention have been simplified the manufacturing process of face glass and have been avoided repeatedly cold machining process, thereby have not only shortened the manufacturing cycle of face glass, have reduced the consumption of consumptive material and manpower, and the mirror-quality of face glass is improved.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
