Description
Technical field
The present invention relates to bend glass hot bending technical fields, more particularly to a kind of bend glass hot bending imprint process.
Background technique
In the 5G epoch, the main trend of smart phone development, as the progress of touch screen technology and production technology are innovated,
OLED screen will more be applied because of its performance advantage on mobile phone.The following flexible curved surface screen mobile phone popularity rate will be higher and higher,
To pull the demand to glass curve screen.Meanwhile non-touch screen mobile phone still occupies a tiny space in market, a portion is high
Terminal type is to meet the requirement of its high-quality will also use bend glass protecting screen.To sum up, following to use glass curve screen mobile phone
Permeability in mobile phone industry will be higher and higher, and the form scale of glass curve screen will gradually expand.Mobile phone Curved screen demand
Scale will keep simultaneously and rapidly increasing with mobile phone market, while requirement of the market to Curved screen can be higher and higher.
Summary of the invention
To solve the above problems, the present invention provide it is a kind of using mold design mating mold processing and hot bending shape technique join
Glass surface is imprinted out the bend glass hot bending imprint process of the pattern wanted and text or shape by number adjustment.
The technical scheme adopted by the invention is that: a kind of bend glass hot bending imprint process includes the following steps,
Step 1, by glass successively sawing sheet, processing, primary cleaning；
Step 2, the glass after cleaning is put into hot bending in mold and forms curved surface；
Step 3, glass heat is extruded into pattern LOGO；
Step 4, glass curve is polished；
Step 5, to glass secondary cleaning after polishing, chemical tempering is carried out after cleaning again；
Step 6, white tiles inspection is cleaned again three times after completing chemical tempering；
Step 7, LOGO printing, four cleanings are carried out afterwards；
Step 8, it is printed, smear, test package after five cleanings.
Further improvement of these options is, in the step 1, to big sheet glass sawing sheet at specified size, after pass through
CNC finishing, carries out passing through ultrasonic cleaning after completing finishing.
Further improvement of these options is, in the step 2, glass is put into hot bending in mold and forms curved surface, hot bending
Time is 80s-100s, and hot bending temperature is 760 degrees Celsius, and hot bending pressure is 0.4Mpa.
Further improvement of these options is that the mold is an integral structure setting.
Further improvement of these options is that the mold is separate structure setting.
Further improvement of these options is, in the step 4, curved surface polishing is to be polished using 3D polishing machine,
Polishing time is 10-120min；Revolving speed is 10-100rpm.
Further improvement of these options is, in the step 5, uses ultrasonic cleaning to glass secondary cleaning, changes
It learns tempering and uses potassium nitrate.
Further improvement of these options is, in the step 6, cleaning is ultrasonic cleaning three times, and white tiles verifies as
Desk checking.
The beneficial effects of the present invention are:
Hot bending graphite jig and mold processing are designed by product drawing, utilizes hot-bending machine adjustment molding, preheating, cooling stations
Temperature and pressure control hot bending after product appearance and size, be mainly adjusted by 700 degrees centigrade of forming temperature and molding
Pressure 0.6Mpa or so, makes product surface mold pattern effect
Mold unitary design: by product drawing directly by design to mold upper and lower mould forming surface, such mode mould
Product size is stablized when having hot bending, needs to polish after the hot bending of imprinted pattern region.
Mold separation formula design: by product drawing that pattern is individually designed for single mold insert, corresponding mold upper and lower mould progress
Grooving cooperates pattern mold insert to process production product, and the processing is simple for such mode mold, and product size and appearance are easy control when hot bending
System, mold insert surface roughness are easy to control, and polishing can not be had to after the hot bending of imprinted pattern region.
In the present invention, glass surface is imprinted using the processing of mold design mating mold and hot bending shape technical arrangement plan
The pattern and text or shape wanted out.
Specific embodiment
