Description
Technical field
The present invention relates to a kind of production methods of liquid metal waterproof cover.
Background technique
Sapphire is used for cam lens, electronic equipment key, screen, cover board and rear cover glass in electronic product
Piece etc..Sapphire is the second largest stiff materials for being inferior to diamond in the world, is used as product screen, translucency, wearability are good, resistance to height
Temperature, screen do not have to pasting protective film.Bonding between sapphire and electronic product casing is typically all to be bonded with glue.Due to being two
A part is bonded together after being separately formed with glue, and the caking property between each section is bad, there is gap, leads to electronic product
Waterproof and dustproof, shockproof function is not achieved.For example, smart phone screen generallys use embedded embedding technique on mobile phone market
Liquid crystal display is embedded in metal center, other than above-mentioned drawback, there is also the disadvantages of the roomy thick thickness of mobile phone frame.
Summary of the invention
It is a primary object of the present invention in view of the deficiencies of the prior art, provide a kind of production side of liquid metal waterproof cover
Sapphire material and liquid metal are integrally formed, make product gapless, reach waterproof and dustproof, shockproof high-performance by method,
Be conducive to screen and realize narrow frame.
To achieve the above object, the invention adopts the following technical scheme:
A kind of production method of liquid metal waterproof cover, comprising the following steps:

Shape；
B. the type for the sapphire sheet material being put into mold is intracavitary, to the intracavitary injection liquid metal of type of mold, makes to fill
In the intracavitary liquid metal of the type around the side of the sapphire sheet material, and the filling shape of the liquid metal be to
The shape of the peripheral part of molding waterproof cover；
C. so that the liquid metal is shunk solidification sizing at a predetermined rate, be incorporated in the side of the sapphire sheet material
Together.
Further:
In step a, the ladder-type structure with gradient is processed into the side of the sapphire sheet material, it is preferable that described
The outermost step of ladder-type structure forms the inclined plane shape of one side clipped corner.
In step a, the technique for forming the sapphire sheet material includes the process of grinding, polishing and cleaning.
In polishing process, polish pressure is in 0.05Mpa~0.21Mpa.
Process of lapping carries out at a constant temperature.
It further include coating binder in the side of the sapphire sheet material before step b.
It further include the upper and lower surface coated in the sapphire sheet material to form protective film before step b.
The liquid metal is zirconium base liquid metal, magnesium-based liquid metal, copper-based liquid metal, aluminium base liquid metal, iron
Any one of base liquid metal, Ni-based liquid metal, titanium-based liquid metal.
In step a, the thickness of the sapphire sheet material is processed into 0.6mm~1.5mm.
Beneficial effects of the present invention:
The present invention using liquid metal have by the particularity of its own structure can injection molding the characteristics of, by side
Sapphire sheet material by processing is put into mold, according to predetermined filling shape inject liquid metal, make liquid metal around
Solidification sizing is shunk in the side of sapphire sheet material at a predetermined rate, so that the side with sapphire sheet material is integrally combined closely
Form electronic product casing together.Specifically, advantages of the present invention is embodied in:
1, screen of the sapphire sheet material as electronic product itself has many advantages, such as hardness height, scratch-resistant；
2, liquid metal has unique light and handy molecular structure, makes electronic product casing part, weight using liquid metal
It measures very light；
3, due to liquid metal molding before feature be can Free Transform, be consequently adapted to neatly be molded into various required
Shape；
4, the electronic product casing being made of liquid metal has excellent electromagnetic performance, corrosion resistance, wearability, high-strength
Degree, high rigidity and high tenacity；
5, the incrustation link of post-processing, liquid metal are more richer than the optional technique of general magnesium alloy,
More preferably visual effect can be obtained；
6, due to liquid metal without magnetism, manufactured electronic product casing on influences such as the antenna of mobile phone and gyroscopes very
It is small；
7, ultra-thin, complicated structure is advantageously implemented by mold one-pass molding by sapphire sheet material and liquid metal,
The processing work that the glue bonding in later period can be saved, greatly reduces process and cost；
8, the mode of integrated injection molding is advantageously implemented the narrow frame of product, to substantially reduce the weight of electronic product
Amount.
9, when liquid metal is cooling, sapphire sheet material is compatible with liquid metal and forms the product of an entirety, and product is public
Poor small, gapless, effectively reaches waterproof and dustproof, shockproof performance；
10, integrally formed structure is conducive to that product is made to obtain bigger visible area, and screen utilization rate is bigger.
Sapphire working process mode and its structure setting employed in preferred embodiment, can promote integrated molding
The quality and reliability of product, improve the yields of product.

Specific embodiment
It elaborates below to embodiments of the present invention.It is emphasized that following the description is only exemplary,
The range and its application being not intended to be limiting of the invention.
Refering to fig. 1 to Fig. 4, in one embodiment, a kind of production method of liquid metal waterproof cover, including following step
It is rapid:
Step a. provides sapphire sheet material 1, and the side of the sapphire sheet material 1 is processed to be suitable for and note in the production process
The shape that moulding material combines；
The type that sapphire sheet material 1 is put into mold by step b. is intracavitary, to the intracavitary injection liquid metal of type of mold, makes to fill
In the intracavitary liquid metal of type around the side of sapphire sheet material 1, and the filling shape of liquid metal is waterproof to be formed
The shape of the peripheral part of shell；
Step c. makes liquid metal shrink solidification sizing, molding liquid metal 2 and sapphire sheet material 1 at a predetermined rate
Side be combined together.
In step a, the technique for forming sapphire sheet material 1 may include the process of blanking, grinding, polishing and cleaning.
Referring to figs. 2 and 3, in a preferred embodiment, in step a, the side of sapphire sheet material 1, which is processed into, has ladder
The ladder-type structure 101 of degree, this design will be advantageous to sapphire sheet material 1 and liquid metal intermeshing and form, at
Type it, very high bond strength can be obtained between rear liquid metal 2 and sapphire sheet material 1.Preferably, above-mentioned ladder-type structure
101 outermost step forms the inclined plane shape 102 of one side clipped corner, to be more advantageous to being intimately associated for the two.
In a preferred embodiment, sapphire sheet material 1 is processed into the thickness of 0.6mm~1.5mm.
