Technical field
The present invention relates to Sensor preparation technical fields, more particularly to a kind of ultra-thin glass sensor and its preparation side
Method.
Background technique
Touch screen is a kind of input equipment for significantly improving man machine operation interface, is had the advantages that intuitive, simple, quick.
Touch screen has been obtained for being widely applied in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system
System etc..
The touch screen of GG structure is bonded by glass cover-plate and glass Sensor, and the touch screen of GG structure is due to tool
There are the performance advantages such as hard wear resistant, corrosion-resistant, high transparency, the manipulation smooth, high reliability of feel to be obtained extensive utilization.At present
The production technology of glass sensor is as follows: make sensor on large stretch of glass substrate, then by large stretch of sensor glass-cutting at
Small sheet glass sensor.For traditional glass sensor thickness in 0.3mm-1.8mm, the thickness of glass sensor is thicker, does not allow more
It is flexible, that is, inadequate bending is enabled, finally as bounce is too high, is finally separated with glass cover-plate, bubble production occurs
Life is bad.
Summary of the invention
In order to make up the defect of prior art, the present invention provides a kind of ultra-thin glass sensor and preparation method thereof.
The technical problems to be solved by the invention are achieved by the following technical programs:
A kind of preparation method of ultra-thin glass sensor, includes the following steps:

S4. large stretch of underlay substrate is bonded by glue-line with the blue film surface of large stretch of glass substrate, obtains functional sheet；
S5. reduction processing is carried out to the second surface of large stretch of glass substrate；
S6. the functional sheet is cut, obtains several small pieces functional sheets；
S7. the small pieces functional sheet is heated, underlay substrate is isolated, obtains ultra-thin glass sensor.
Further, the concrete operations of step S4 are as follows: (1) large stretch of underlay substrate is provided；(2) in large stretch of underlay substrate
Silk-screen epoxy glue on surface；(3) the epoxy glue surface of large stretch of underlay substrate is bonded with the blue film surface of large stretch of glass substrate, is obtained
To functional sheet.
Further, the temperature heated in step S7 is 60-150 DEG C.
Further, in step S1, the thickness of the sheet glass substrate is greater than 0.4mm.
Further, the ultra-thin glass sensor with a thickness of 25-300 μm.
Further, the underlay substrate is glass substrate.
Further, in step S5, or chemical reduction thinned to the second surface progress physics of large stretch of glass substrate.
Further, after the second surface to large stretch of glass substrate carries out chemical reduction, to the second surface
It is processed by shot blasting.
In order to prepare ultra-thin glass sensor, this field is usually to big after the surface of large stretch of glass substrate makes sensor
Sheet glass substrate carries out reduction processing, but inventor is in practice, it has been found that using existing technique, due to large stretch of glass substrate
Support force is small, in thinning process because large stretch of glass substrate be bent due to have an impact to thinned uniformity, while Sensor breakage rate compared with
It is high.Based on the above issues, large stretch of glass substrate is first bonded together by the present inventor with underlay substrate, wherein large stretch of glass substrate
On sensor towards the underlay substrate, to enhance the support force of large stretch of glass substrate, reduce in thinning process because of sheet
Glass substrate is bent and the influence to thinned uniformity, while also reducing Sensor breakage rate.It, can be with using technique of the invention
Glass substrate, while the yield rate with higher in thinning process is largely thinned.But will be thinned after large stretch of glass
After glass substrate cut is at small pieces, the separation of ultra-thin glass sensor and underlay substrate is difficult, is in ultra-thin glass sensor and lining
Glue-line between substrate remains in ultra-thin glass sensor during the separation process, has in separation process to ultra-thin glass sensor
Biggish damage.To solve the above-mentioned problems, inventor has found by numerous studies, first in sensor silk-screen indigo plant film, then will be big
Piece underlay substrate is bonded by epoxy glue with the blue film surface of large stretch of glass substrate, is then carried out to large stretch of glass substrate thinned
Processing after large stretch of glass substrate after being thinned is cut into small pieces, by heat treatment, makes blue film not have viscosity, so as to
Ultra-thin glass sensor to be separated with underlay substrate easily, can prevent in ultra-thin glass sensor and underlay substrate it
Between glue-line remain on ultra-thin glass sensor during the separation process, be effectively reduced during the separation process to ultra-thin glass
The damage of sensor.
The present invention also provides a kind of ultra-thin glass sensor, are prepared by the above method.
The invention has the following beneficial effects:
The ultra-thin glass sensor thickness obtained using preparation method of the invention is small, and good bending property is fitted in glass cover-plate
Afterwards, it can be bent according to the shape of glass cover-plate, be not in bubble with the closely connected conjunction of glass cover-plate, improve the good of product
Rate.
