Abstract
The invention discloses a method for preparing blue glass for high-pixel smart phones. The method comprises the following steps: (1) dividing a large piece of blue glass into small pieces of glass; (2) machining the boundary dimension; (3) performing chamfering; (4) cutting the blue glass into sheet shapes through multi-line cutting; (5) beveling the sheet-shaped blue glass; (6) using a high-accuracy thickness gauge and a millstone device for grinding; (7) performing polishing; and (8) using an ultrasonic cleaner containing a blue glass cleaning agent for cleaning. The granularity of a resin abrasive wheel is 700 meshes; the pressure of the millstone device is smaller than 1.0MPa, the rotation speed is smaller than 20 Rpm, and the parallelism degree among millstone abrasive surfaces of the millstone device is smaller than 0.005mm; the PH of the blue glass cleaning agent is about 7.0; the error precision of the high-accuracy thickness gauge is smaller than or equal to 0.005mm; and the power of the ultrasonic cleaner is smaller than 40 kHz. By means of the method, not only the quality of the blue glass can be improved, but also the first pass yield is not lower than 80%.
Description
Technical field
The present invention relates to photoelectric field, be specifically related to the preparation method that a kind of high pixel smart mobile phone is used smalt.
Background technology
At present, 8,000,000 and the smart mobile phone of above pixel to adopt ultra-thin smalt to absorb infrared as main flow, the demand of smalt increases day by day.Existing high pixel smart mobile phone comprises the steps: with the preparation method of smalt
(1) the bulk smalt is divided into the fritter smalt;
(2) adopt resin emery wheel processing appearance and size;
(3) chamfering;
(4) with multi-thread cutting smalt is cut into sheet;
(5) sheet smalt bevelling;
(6) adopt high accuracy thickness measuring instrument and mill device to grind;
(7) polishing;
(8) adopt the supersonic wave cleaning machine that the smalt cleaning agent is housed to clean.
Smalt thickness commonly used is 0.21mm, and smalt is phosphate glass.Smalt hardness has only Mohs about 4.20, and soft nearlyer 2/3 than general glass, itself is highly brittle.So in adopting above-mentioned process, there is following difficult point:
(1) no blue tinted glass can't clean up, and the problem that its surface is corroded usually takes place.
(2) can't accurately calculate and be ground to the needed number of turns of finished product thickness and time, need repeated multiple times to rise and grind again after mill is measured thickness.
These difficult points cause in the process smalt to be easy to produce frightened splitting, scratch, and problem such as surface clean is unclean, its first-pass yield has only about 40%.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of high pixel smart mobile phone with the preparation method of smalt, its can solve in the process smalt produce frightenedly split, scratch and the clean problem of cleaning, and first-pass yield is not less than 80%.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of high pixel smart mobile phone preparation method of smalt, it comprises the steps:

(5) sheet smalt bevelling;
(6) adopt high accuracy thickness measuring instrument and mill device to grind;
(7) polishing;
(8) adopt the supersonic wave cleaning machine that the smalt cleaning agent is housed to clean;
The granularity of described resin emery wheel is 700 orders; Described mill device pressure is less than 1.0Mpa, and rotating speed is less than 20Rpm, and the depth of parallelism between the mill abradant surface of described mill device is less than 0.005mm; The pH value of described smalt cleaning agent is about 7.0; The error precision of described high accuracy thickness measuring instrument is smaller or equal to 0.005mm.
Preferably, the power of described supersonic wave cleaning machine is less than 40KHZ.
Preferably, the error precision of described high accuracy thickness measuring instrument is less than 0.005mm.
Pass through technique scheme, a kind of high pixel smart mobile phone provided by the invention preparation method of smalt, solved and ground, needing repeatedly, repeatedly to rise mill in the polishing smalt process and measure thickness and cause frightened splitting, clean clean in scratch and the cleaning process and problem such as corrosion smalt surface, thereby improved the quality of smalt, and made first-pass yield be not less than 80%.
The specific embodiment
