Embodiments herein is described below in detail, those skilled in the art is it will be appreciated that following example is intended for solving
The application is released, and is not construed as the limitation to the application.Unless stated otherwise, it is not expressly recited in embodiment below specific
Technology or conditions, those skilled in the art can be according to common technology or conditions in the art or according to product description
It carries out.
In the one aspect of the embodiment of the present application, a kind of applying method of overlay film bend glass is proposed.
According to an embodiment of the present application, with reference to Fig. 1, applying method includes:
S100: diaphragm is fitted in the planar section of bend glass in advance.
In this step, diaphragm 200 is fitted in the planar section 110 of bend glass 100 in advance, in this way, in advance by diaphragm
200 a part is bonded completely with planar section 110, can be driven bubble from centre out of, to make the plane of overlay film bend glass
Part 110 is smooth and bubble-free or fold.
In some embodiments of the present application, with reference to Fig. 2, it is bonded the pressure for using plane jig 400, and being bonded in advance in advance
Power can be able to be 0.5~2min for 10~50N, time.In this way, it is flat that (20~30 degrees Celsius), which pass through lower surface, at normal temperature
A part of diaphragm 200 is first bonded by the jig 400 in face with planar section 110, and can using the condition of above-mentioned pre- fitting
It fully ensures that and is bonded bubble-free or fold between diaphragm 200 and planar section 110.
According to an embodiment of the present application, the material for forming diaphragm may include thermoplastic polyurethane (TPU), in this way, using tool
There is the soft diaphragm of the TPU of good tensile property, diaphragm 200 can be bonded in the complicated inner surface of three-dimensional (3D) bend glass.
S200: deformable profiling jig is put into surface of the diaphragm far from bend glass, and carried out to profiling jig etc.
Static pressure fitting, so that diaphragm is fitted in the curvature portion of bend glass.
In this step, with reference to (a) of Fig. 3, deformable profiling jig 300 is put into diaphragm 200 far from bend glass
100 surface, and with reference to (b) of Fig. 3, equal static pressure are carried out to profiling jig 300 and are bonded, so that diaphragm 200 is fitted in curved surface glass
The curvature portion 120 of glass 100, and obtain overlay film bend glass.According to an embodiment of the present application, the specific shape of bend glass 100
Shape those skilled in the art can correspondingly be designed according to the face shaping that overlay film bend glass needs.In some of the application
In embodiment, the bending angle of bend glass 100 can be not less than 70 °.In other embodiments of the application, bend glass
The 100 corresponding central angle of curvature portion 120 can be greater than 90 °.
Present inventor has found that general hydraulic way is applied on 300 surface of profiling jig in the course of the research
Pressure be it is non-uniform, be also easy for making generating bubble between diaphragm 200 and bend glass 100.So inventor selects pressure
Product, i.e., be placed into closed container and applied by liquid to product each to same by the equal static pressure mode of power more evenly
Pressure can apply power more evenly, so that diaphragm 200 be made more uniformly to be fitted in curvature portion to 300 surface of profiling jig
120, also, fold will not be played between diaphragm 200 and bend glass 100 or generate bubble, and then it is big to produce side wall central angle
In 90 ° of overlay film bend glass.Moreover, multiple products can be disposably put into the closed container of static pressure mode and carry out simultaneously by waiting
Pressurization, has the potentiality of volume production in this way.
According to an embodiment of the present application, formed profiling jig 300 specific material, as long as this material can deformation,
Specific such as silica gel, rubber elastomeric material, those skilled in the art can be according to the actual pressure for waiting static pressure to be bonded and finally real
Border fitting effect is correspondingly selected.In some embodiments of the present application, the material for forming profiling jig 300 can be silicon
Glue, in this way, the profiling silica gel jig moderate using above-mentioned tensile strength, can bear the pressure within 100MPa, and can make diaphragm
200 uniformly fit to curvature portion 120.
According to an embodiment of the present application, the shape of profiling jig 300 can be pair with the inner surface configuration of bend glass 100
It answers, in this way, liquid can equably be transmitted to film to the uniform pressure of profiling jig 300 again during equal static pressure fitting
Surface of the piece 200 far from bend glass 100, so as to make diaphragm 200 more uniformly be fitted in curvature portion 120.In the application
Some embodiments in, after deformable profiling jig 300 is put into surface of the diaphragm 200 far from bend glass 100, profiling
Gap between jig 300 and the inner surface of bend glass 100 can be 2~3mm, imitate before static pressure fitting in this way, facilitating and waiting
Being put into for shape jig 300 and taking out later.
According to an embodiment of the present application, profiling jig 300 can be solid, in this way, can to avoid profiling jig 300 because
For therein deformation to diaphragm 200 lead to the problem of pressure it is non-uniform, so that diaphragm 200 be enable more uniformly to be fitted in song
Face part 120.
It, can be to the curved surface glass for being placed with profiling jig 300 before step S200 in some embodiments of the present application
Glass 100 first carries out Vacuum Package, takes out very after the bend glass 100 for being placed with profiling jig 300 is for example specifically put into plasticity bag
Sky, in this way, can prevent the liquid such as water from penetrating into during equal static pressure fitting, to make the good of the overlay film bend glass produced
Product rate is higher.
According to an embodiment of the present application, the technological parameter of static pressure fitting is waited, specifically such as class of liquids, pressure and time
It can be carried out correspondingly according to the practical curved surface radian of bend glass 100, the actual (real) thickness of diaphragm 200 Deng, those skilled in the art
Adjustment.In some embodiments of the present application, with reference to Fig. 4, wait static pressure fitting that segmented pressuring method can be used, first 20~
5~10min of precharge (i.e. Δ t1=t2-t1) is carried out under the pressure P1 of 40N, then rises under the pressure P2 of 20~40N and is added
It presses 10~20min (i.e. Δ t2=t4-t3), in this way, can will be between diaphragm 200 and curvature portion 120 when precharge step
Bubble is driven out of, then boosts to laminate pressure again, and diaphragm 200 of the thickness no more than 0.5mm and curvature portion 120 can be made complete
Fitting.
In some embodiments of the present application, the temperature for waiting static pressure to be bonded may be 40~60 degrees Celsius, in this way, can be with
Soften the diaphragm 200 of polymer material, to be easier to fit to curvature portion 120 under the pressure of profiling jig 300
Surface, also, it is avoided that the problem of profiling jig 300 will cause internal stress or even micro-crack to the stretching of diaphragm 200, and then make
Diaphragm 200 and being bonded for 100 inner surface of bend glass are stronger.
In some embodiments of the present application, after step S200, Vacuum Package is opened, original-shape can will be restored
Profiling jig 300 take out, in this way, can get overlay film bend glass, also, the specific structure of overlay film bend glass can refer to figure
5。
In conclusion according to an embodiment of the present application, proposing a kind of applying method, profiling jig and equal static pressure can be passed through
Diaphragm is uniformly fitted to wide-angle glass inner wall, is not limited by glass shape by laminating type, also, diaphragm and curved surface glass
