Abstract

The invention provides a manufacture method of mobile phone glass and belongs to the glass processing technical field. According to the technical scheme of the invention, the manufacture method comprises the following steps that: glass is cut so that the glass can be in a certain size and is required to be processed, and the size of the cut glass is larger than the size of an actual frame by 0.15 to 0.20mm; the glass is processed and slotted, and the edge of the glass is chamfered; the glass is put into a cleaning tank filled with pure water, and ultra sonic vibration is performed, and therefore, the surface of the glass can be cleaned; and the glass is heated to 600 DEG C, and then, the glass is cooled rapidly through utilizing air or a salt solution; ink printing is performed on the surface of the glass; and the printed glass is put into a baking oven so as to be baked, after the glass is cooled, and film coating and packaging are performed on the glass. The glass manufactured by the manufacture method has beautification, decoration and protection functions. The manufacture method can be mainly used for manufacturing small-sized products such as mobile phone lenses and MP3 lenses.

Description

The manufacture method of mobile phone glass

?

Technical field

The invention belongs to glass working arts field, particularly relate to a kind of manufacture method of mobile phone glass.

Background technology

Benefit from maintaining sustained and rapid growth of global communication market, the whole industry of mobile phone also achieves unprecedented development achievements, and people are also just more and more higher to mobile phone quality requirements, thus initiation internationally renowned brand is also increasingly strict to the dimensional requirement of mobile phone.

Mobile phone glass is category of glass product, is mainly ultra-thin glass (0.4-1.0mm is thick), hacks through glass, product that a series of special processing process such as imitative type edging, polishing, sclerosis, ultrasonic cleaning, vacuum coating, silk-screen is made.

Summary of the invention

The invention provides a kind of manufacture method of mobile phone glass, the technical solution used in the present invention comprises the steps:

(1) by the processing dimension required for glass-cutting one-tenth, the 0.15-0.20mm larger than actual housing size of the size after cutting;

(2) glass processing fluting, glass edge chamfering;

(3) glass is put into the rinse bath that pure water is housed, vibration of ultrasonic wave cleans glass surface in addition;

(4) by glass heats to 600 DEG C, then with air or salting liquid, it is cooled rapidly;

(5) ink printing is carried out to glass surface;

(6) glass printed is put into oven to toast, after cooling, carry out overlay film, packaging.

The mobile phone glass that the manufacture method of mobile phone glass of the present invention is obtained, it has the function of beautifying and decorating and protection, and current product object is mainly the small-size products such as mobile phone (LENS) eyeglass, MP3 eyeglass.

Embodiment

Below in conjunction with embodiment the present invention made and further illustrating.

Operation one: (section)

Section (also known as blanking).Blanking is by monolithic glass, cuts into required processing dimension according to engineering drawing, glass must be split into facilitate than the large 0.15-0.20mm of outline pattern on drawing follow-uply to prepare for edging and chamfering.

Use equipment is slicing machine.

Processing procedure use raw material is: blue or green thickness of glass is generally 0.9mm, 1.1mm

Quality standard is: glass can not have the scuffing of severe, collapses limit, slight crack and size depart from.

Operation two: (CNC fluting and bevelling)

CNC processing goes out groove in the glass processing that blanking is good and glass edge is poured out angle, makes glass have the ability of good anti-scratch.

Use equipment is CNC carving machine (there are Christian Dior numerical control, permanent numerical control far away in general device supply producer), and equipment software is: 6 interlock configurations.AB glue is used to be adhered on board by silica gel base during work, size required when using milling cutter base to be processed into work, adopt vacuum suction to be fixed by the glass of required processing, then adopt break bar to slot to glass and the processing of edging chamfering and process.

Equipment use tool and cutter: milling cutter, break bar, pressing plate base.

Equipment consumptive material service condition: equipment use cutting fluid, the proportioning of cutting fluid is (1:20)

The effect of cutting fluid: 1, clean 2, antirust, 3, cooling, 4, lubrication

The general 7-8 of production capacity hundred (production capacity because of the difficulty difference of product processing technique depart to some extent)

Quality standard is: glass is processed into required size according to drawing, and overall dimension can have the error (± 0.03mm) of probably ± 3 silks, and the Quadratic Finite Element of use carries out dimensional measurement (sampling observation).

Operation three: (Ultrasonic Cleaning)

So-called hyperacoustic cleaning is that pure water is put into rinse bath, in addition the operation that cleans glass surface of vibration of ultrasonic wave.

White tiles initial survey can be carried out to it, if checked whether that glass collapses limit and surface tear glass surface needs glass directly to send into tempering operation without scratching and collapsing limit after glass cleaning.Remedy if glass surface has scuffing feeding ground section to carry out grinding.

Equipment regular maintenance uses soda bath to clean.

Operation four: grinding (glass plain grinding)

If there is surface abrasion and scuffing in operation three, need glass to put into that plain grinding is carried out in grinder inside, by the proportioning of polishing powder and interpolation, the principle of being closed by water mill is by the flaw of glass surface, and cut is eliminated.

Milling apparatus (plant equipment Co., Ltd is found in Central China by Shenzhen) flat-grinding machine

Tool is used to use consumptive material for dental lamina: polishing powder (cerium oxide, iron oxide)

Clean again after grinding, carrying out white tiles detection (can scrap if plain grinding cannot be revised for twice), if cut is remedied successfully can enter tempering operation.

Operation five tempering: glass tempering

So-called glass tempering, is by glass heats to 600 DEG C close softening temperature, it is cooled rapidly, thus reach the mechanical strength and thermal stability that promote glass with air or salting liquid.The item that quenching should be noted that wants Homogeneous cooling, thus eliminate the internal stress of glass.The time that processing needs is generally at about 4h.

Use equipment: annealing furnace use consumptive material is: nitrous acid

Detection method and standard: tempering bead 110g, height 30cm, falls, nine grids position measurement.

Operation six silk-screen: ink printing is carried out to toughened glass glass surface.

Use equipment: Dongguan Shuan He silk-screen machinery, star gather the star of lean.

Use consumptive material ink: add in ink and appropriate open profit, stir, add two defrothers, stir.

Quadratic Finite Element detects, positive and negative two silk error ranges.

Operation seven is toasted: the glass screen that silk-screen is good is put into oven and toasts, and the ink of glass surface is toasted.

Baking machine (unit of Shenzhen wound electroheat equipment)

Operation eight overlay film: the glass processed is packed.

1. equipment laminating machine is used.2. consumptive material overlay film is used.

3. the technological standards of overlay film: need before overlay film to carry out visual inspection work, glass vision panel surface is without scratching and polluting (jack), silk-screen edge without burr, crackle and other abnormal conditions.After overlay film: should not bubble be there is with the laminating of glass surface after overlay film, wait other abnormal conditions.

Claims

1. a manufacture method for mobile phone glass, is characterized in that comprising the following steps:

(2) glass processing fluting, glass edge chamfering;

(5) ink printing is carried out to glass surface;

2. the manufacture method of mobile phone glass according to claim 1, it is characterized in that: in step (3), find that glass surface has wearing and tearing and scratches, glass need be put into grinder inside and carry out plain grinding, by the proportioning of polishing powder and interpolation, the flaw of glass surface and cut are eliminated.
