Description
Technical field
The present invention relates to glass working arts field more particularly to a kind of plate glass processing methods with functional circuit.
Background technique
Glass plate with functional circuit, for example, touch screen circuitry (OGS), is widely used in the electronics such as mobile phone, tablet computer
Product.Damage of the glass when falling in order to prevent, common process are using chemical products, such as potassium nitrate
(KNO3) solution, does chemical intensification treatment, and hand-set lid glass is similarly handled using this kind of chemical strengthening method.Currently
Representational OGS glass processing process mainly has two ways, such as following:
1. not strengthening big glass sheet → production surface protection film → cutting off processing (being cut into single sheet) → outer peripheral grinding
→ cleaning → surface polishing → cleaning → chemical strengthening → cleaning → functional circuit production → decoration → cleaning → completion.
In the method, the production of functional circuit is in the last one process, does not need to set protective film on functional circuit, work
The damaged condition of functional circuit can be less in the process, and yield is high.Although this method is a good mode, because being
Monolithic produces one by one, it is necessary to the equipment of a large amount of same types be arranged, production efficiency is low, batch production is difficult, and there are costs
High disadvantage.
2. the big glass sheet → cleaning → functional circuit production → decoration → production surface protection film of reinforcing after grinding (makes
With hydrofluoric acid) → cutting off processing (being cut into single sheet) → outer peripheral grinding → protective film peeling → cleaning → production is hydrogen resistant
Fluoric acid protective film → glass product contoured peripheries processing (etching glass product contoured peripheries by high frequency) → hydrofluoric acid resistant is protected
Film peeling → cleaning → finished product.
In second method, the big glass sheet after grinding, chemical strengthening is cleaned first, makes functional circuit, dress
Decorations (as needed, sometimes without), then make protective film, make surface protection to functional circuit and decoration whole face.Again on reverse side
Cutting makes big glass plate become the small glass plate of monolithic.Then the glass sheet after cutting is ground using grinding machine one by one, is made into
Then the periphery of the conical surface and polishing removes protective film using solvent.After washing, protected in the two-face printing hydrofluoric acid resistant of glass
Then film etches and removes microcrack the periphery of glass sheet with hydrofluoric acid.The glass that finishes is etched, then is cleaned with solvent resistance to
Fluorinated, acid protective film, is and then cleaned with cleaning solution, completes processing.
In second method, since functional circuit is starting just to have made, need in subsequent process to function
Energy circuit surface is protected, and adding protective film layer prevents scratch.In addition, in order to which hydrofluoric acid to be used (HF) is removed after grinding
The microcrack that glass end face occurs needs to stamp the protective film of resistance to fluoric acid.Therefore protective film needs to print twice, and every time
It needs using solvent protection film stripping, and cleaning process is also necessary.This method cost is also very high.
In addition, remove acid etching carved glass using hydrofluoric acid, the range of acid etching be within the shape to 0.2mm of glass in
Side is 0.05-0.06mm with the length that the microcrack that hydrofluoric acid removes includes chipping, and depth is 0.015-0.02mm, glass
Plate periphery will be directed at position with protective film, this requirement is very high.The general required precision for requiring alignment position is on the left side 0.05mm
The right side is easy residual microcrack if not reaching requirement.After if rejected product is mixed into, it is possible in subsequent screen printing
The problems such as ink exudation occurs when brush.Therefore, although this method can realize volume production, the physical strength of product is highly unstable
's.
In conclusion how to avoid using in process of production is harmful hydrofluoric acid (HF) to human body and environment, simultaneously
The high-intensitive and stable physical strength for guaranteeing production glass substrate, reduces disqualification rate, it is urgently to be resolved in the industry for reducing cost
The technical issues of.

Detailed description of the invention
Fig. 1 is the process flow chart of the method for the present invention.
Specific embodiment
In order to keep the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with drawings and examples to this hair
It is bright to be described in detail.It should be appreciated that following specific embodiments only to explain the present invention, do not constitute limit to the present invention
System.
Cover-plate glass for electronic product is initially to belong to simple glass, after grinding and polishing processing has been completed on surface
Reach optical mirror plane requirement, but surface is very fragile.Since touch screen face glass is than relatively thin, surface smoothness requires height again,
Forming difficulty, manufacturing process are more much more complex than general plate glass, in the manufacturing process of touch screen, from sliver, imitative type, CNC
(finishing impression processing) all easily causes a degree of scrape to glass substrate in board or other operations until processes such as polishings
Wound, scratch rate increase the manufacturing cost of enterprise and constrain the production capacity of enterprise generally 42% or more.So processing
Pasting all kinds of protective materials on face glass surface when touch screen is necessary.Protective layer is required in subsequent cutter
Can also remain unchanged after sequence and CNC finishing impression manufacturing procedure and hairbrush attrition process process can reach good protection to glass surface
Property.
There are mainly three types of modes for existing glass protection: first is that patch peelable glue, second is that patch protection film, third is that printing protection
Ink.Wherein: the mode for pasting peelable glue is not suitable for large stretch of production and the edge side Hui Qi during CNC numerical control finishing impression, needs
It is removed per a piece of tear-off, inefficiency.It is cheap that the mode of patch protection film makes simple consumptive material, but equally faces inefficiency
Problem.The mode of printing protection ink is protected mode optimal so far, is suitable for scale of mass production, protecting effect is good.
Then, protection ink performance currently on the market is immature, is not easy to move back film, and cleaning is difficult, can be big in high volume production process
The amount consumption production time, and increase human and material resources cost.
Above-mentioned three kinds of protected modes after processing is completed, need each layer protective glue cleaning removal.In actual production, generally
It can not disposably wash, staff is needed to tear protective layer off by hand, not only working efficiency is lower, but also easily causes work people
Member's hand is corroded.In addition, it is usually necessary to use UV solidifications for above-mentioned three kinds of protected modes, and the disadvantage is that: it is removed after UV solidification
Trouble, will be removed using hot water；It cannot be with the rear completely compatible cooperation of procedure technology equipment；It can not achieve band film to cut.
In plate glass processing method proposed by the present invention with functional circuit, hydrofluoric acid is replaced to protect using resin protection film
Cuticula, and be coated on glass using silk-screen printing technique.
Resin protective layer has the advantage that
(1) resin is neutral material, environmentally friendly, safety, environmental protection.
(2) hot water is removed after solidifying, and neutral hot water does not injure and corrosion products, avoid the removing of traditional lye to glass and
The corrosion of route, removing rapidly, conveniently, it is safe and environment-friendly.Suitable for producing in enormous quantities, human and material resources are saved.
It (3) can be with the rear completely compatible cooperation of procedure technology equipment, comprising: a, which adapts to break bar cutting technique, (has cutter
There are the break bar equipment or the not no break bar equipment of slotting function of slotting function in head front);B adapts to laser cutting parameter；C is adapted to
Fixed abrasive cuts and (includes: the processing of CNC finishing impression grinding stone and DICING blades machining etc.)；D floating abrasive material is cut
Cutting off processing, preceding mixing water jet cutting processing, rear mixing water jet cutting processing) etc..
(4) it can be realized band film to cut.Resin protective layer can adapt to each process equipment and realize that band film is cut, and reduce guarantor
The difficulty of resin printing and the simplification of cooperation are protected, large-scale production demand is suitable for.
(5) it can be realized the printed dimensions requirement of different-thickness.It needs in lamination process and attrition process for difference
Product attrition process condition set different stacking gaps.The print thickness range of resin is 0.01-0.2mm.
(6) it can be realized self-positioning fastening after protecting laminated resin.The stacking contraposition of glass is very simple, but is being added
It will appear unbalance stress or the overweight phenomenon of stress during work, the case where product for causing stacking to align deviates, cause
The yields of product processing fluctuates.Common practice is all that there is the double-sided adhesive film of caking property to carry out adhered layer for replacement
It is folded, original glass protection material must be removed in this way, cause complex operation, the raising of cost and the drop of production efficiency
It is low.And resin is protected to can be realized the performance in gas producing formation poststack self-positioning fastening, same two panels protects resin meeting after compression
Self-adhesive phenomenon is formed, the degree of adhesion between product can greatly be promoted, prevents occurring product offset in process
Situation guarantees product processing quality, saves production and processing cost.
(7) it can adapt to process not conflict phenomenon during attrition process.The mode of product attrition process mainly uses hair
Brush grinding and polishing.Hairbrush grinding and polishing is that hairbrush brush filament is made to carry out attrition process and end to laminated product end face by rotary motion
The chamfer machining in face.The chamfer machining of end face is carried out to the glass being laminated, it is necessary to hairbrush brush filament be made to be able to enter stacking
Within the gap of glass plate, and the protection resin material for forming glass laminated gap has certain water solubility, can grind
There is solvent nature in edge in process, and hairbrush brush filament will not be prevented to enter in stacking gap and added to product progress edge chamfer
Work.
(8) protection resin can be fabricated to different colours and transparency.Different subsequent machining technologies have it is respective not
Same demand, protection resin can cooperate cutting technique demand freely to arrange in pairs or groups and arbitrarily convert, be suitble to the requirement of each technique.
As shown in Figure 1, the plate glass processing method detailed process proposed by the present invention with functional circuit is as follows:
Big glass sheet is ground and strengthen → make functional circuit → using resin production protective film → cutting off processing (cutting
At single sheet) → individual plates glass laminated → periphery is ground → are laminated glass sheet and → hairbrush grinding → protective film warm water are laminated again
Removing → finished product.
Core of the invention is to replace hydrofluoric acid protective film using resin protection film, and be coated in using silk-screen printing technique
On glass.The preferred polyethylene glycol of protective film resin material (POLYETHYLENE GLYCOL) used in the present invention, which exists
30 degree or less are poorly soluble, easy to dissolve at 50 degree or more.The range of thickness after the resin of printing is dry in 0.01-0.2mm
It is interior.
Polyethyleneglycol resins protective layer can dissolve in the hot water, when monolithic or plurality of plates glass plate are laminated, resin protection
Film can be realized the bonding between glass product and glass product while product is printed in protection.Protective film is in addition to can be used as
Outside solid, stacking intermediate gap when hairbrush grinding can also be made, realize that gap is shared.Pass through secondary stacking, a grinding
Quantity out is 10-50 times of single process, this is very favorable to the processing of sheet glass.In addition, polyethylene glycol is protected
Cuticula resin dissolves in the hot water forms organic compound, and to human body and environmentally friendly, and material can recycle reuse.
The small glass plate of monolithic be once laminated after the width with a thickness of 10-20mm, depending on grinding stone.Small glass plate stacking
Block be laminated again after with a thickness of 100-500mm, be specifically dependent upon the width of hairbrush.
Peripheral grinding is usually band cone angle grinding, and right angle grinding can be used without cone angle in the present invention.
Hairbrush grinding and polishing is the glass by forming marginal belt angle to glass end surface grinding.Pass through hairbrush grinding and polishing
With the size of glass gap size and brush filament, the contact angle and contact pressure of glass and brush filament can be controlled.Hairbrush is ground
The size of mill amount is directly proportional to the hardness of the abrasive grain of the rebound degree grinding agent of brush filament and size.
The purpose of hairbrush grinding and polishing is the microcrack that can be removed around glass product.The present invention does not have to use hydrogen fluorine
Acid only need to use hairbrush grinding that can remove microcrack, can realize the stability and high quality and height of product physical strength
The batch production requirements of output, and because not having to hydrofluoric acid to human body and environment without any injury.
Protection resin is able to use hot water and warm water is removed, and is grasped without any cleaning agent or remover
Make.More easily realize the stability of product physical strength and the batch production requirements of high quality and high-throughput.
In one embodiment, plate glass processing method proposed by the present invention includes following process:
Step 1. carries out grinding and intensive treatment to big glass sheet plate.
Step 2. makes functional circuit on a glass.
Since functional circuit is for acid, alkali, wound, dirt is all very weak, so protective film must be used.
Step 3. uses silk-screen printing technique printing resin material protective film on big glass.
Protection resin is printed on to the surface that functional circuit is had on glass by screen printing mode.The resin of printing is dry
Thickness can keep same thickness in same a batch processing in the range of 0.01~0.2mm after dry.
In the reverse side of the glass plate with functional circuit subsequent needs can also can be left on protective film with printing protective film
The part of cutting processing.The purpose of the two-face printing protective film of glass plate is that the surface of glass is protected to prevent from scratching.
When printed on both sides it is glass laminated when, certain gap, the tree that screen printing brushes are formed between glass and glass
Rouge layer also can be used as grinding interval and use.
Step 4. cutting off processing.
It in cut off operation, is cut in protective film printing surface with cutting machine, big glass plate is cut into single small glass plate.
The small glass plate stacking of step 5. monolithic.
In the small glass plate lamination process of monolithic, the small glass plate of the monolithic cut is carried out to stacking and the fixation of monomer.
Glass sheet arranges stacking on the basis of end face, and in 10-20mm range, specific choice cooperates in next process the thickness of stacking
The width of grinding stone used in shape grinding.
The small glass plies poststack of monolithic, glass plate and glass plate form certain gap, and are able to maintain flatness.Example
Such as, 40 μ of thickness of protective film, together, the gap of glass plate and glass plate becomes 80 μ to two opening and closing of glass sheet.Due to tree
There is adhesion characteristic between rouge, be soaked in water before being laminated when bonding force is weak, or then bubble is laminated in warm water.Monolithic is small
Glass plies poststack pressurizes on the two sides of glass plate, forms the stacking block of square.
The grinding of step 6. periphery.
The stacking block to form quadrangle is laminated in small glass plate, is ground using hairbrush to stacking block end face.The process is not
With carrying out chamfer machining, but right angle grinding is carried out to glass plate.
Hairbrush grinding purpose be glass edge make cone angle, the process it is important that control glass and glass gap,
Guarantee correct thickness, and there is no error between thickness.The fibre diameter of brush when hairbrush is ground is in glass plate and glass
The shape of the gap control edge angle of plate.
The small glass plate stacking block of step 7. is laminated again.
After the grinding of block shape is laminated, lamination process again, the thickness 100-500mm of stacking are carried out on the basis of end face.If
If the quantity that stacking block is laminated again is too many, for example, glass plate must be fixed just in the situation of stacking thickness 100mm or more
High-precision processing can be reached.
The grinding of step 8. hairbrush.
Hairbrush milling apparatus has the hairbrush milling apparatus of longitudinal-transverse type, though there are two class grinding method, substantially using any
Class is ok, and compatible linking can be carried out in technique.
Longitudinal type hairbrush grinding can a hairbrush complete cycle, the quantity once ground is seldom, needs to grind for a long time.Generally
Working ability be 200~250, glass of 0.55mm, process time is that (the reinforcing depth of chemical strengthening was about in 120 minutes or so
The glass sheet of 10 μ).
The glass being laminated is placed on to controlling of longitudinally rotating when with longitudinal type hairbrush grinding device, in second of lamination process
On tool, apply pressure up and down, by the fixed pillared state of the glass of stacking, then makees hairbrush grinding from left and right.
Horizontal type hairbrush grinding is each side, and each angle is individually ground.On the fixation price fixing of horizontal type hairbrush grinder, put
Glass after setting second of stacking fixes the glass being laminated in the left and right on stacking side, and hairbrush is ground since top.Processing
Ability is the glass of a 0.55mm, and with 450~1000, the process time on one side is 15~20 minutes, due to fixed price fixing
Glass be vertical fixation, so can also be with uniformly applied big pressure to the pressure of glass, abrasive power be also stable, high-precision
It can obtain high abrasive power.
By the contact method of glass and hairbrush after stacking, the shape from end face to chamfering be it is variable, according to different
The direction of motion at the edge and hairbrush of machined parameters and condition adjustment glass.Direction can be relatively parallel lapping mode, or
Person is into the lapping mode of squareness.
The control of end face edge angle is the diameter control with the fiber in the gap and hairbrush of glass and glass.The fibre of hairbrush
The diameter of dimension must be greater than the gap between glass and glass.For example, the gap of opposite 0.08mm glass, sets hairbrush fiber
Diameter be 0.4mm, hairbrush grind 30 minutes after, produced at the edge 0.15mm of glass surface, 45 degree of circular edge
Angle；Or the gap of opposite 0.08mm glass, it is set as printing the diameter 0.3mm of the fiber of hairbrush, hairbrush is ground 30 minutes
Afterwards, about 60 degree of circular edge angle is produced at the edge 0.15mm of glass surface.
Abradant hairbrush, generally using materials such as pig hair, nylon or staple fibres.As the condition of grinding hairbrush, instead
Elasticity is big, and in order to keep full of moisture content state on hairbrush, wherein hygroscopicity is big, because of contact of the hairbrush with glass in water
Point can become high temperature, so hairbrush needs to be heat-resist material.In the present invention, big using rebound rate, although hygroscopicity
Less, the PET (Polyster) with good heat resistance and the 66nylon nylon fiber close to pig hair property have obtained good
As a result.It is soft although pig hair performance is fine, there is good elasticity, there is also hair diameter is uneven, very carefully, it is difficult to which what is used asks
Topic.
It is the comparison of several fibers below:
Fiber name hygroscopicity (%) uses temperature rebound rate (kg/mm2)
6nylon 10.7% 100 200-400
66nylon 8.5% 120 400-600
PP 0% 80 800-1000
PET 0.4-0.5% 140 1,100-2000
Grounds travel generally uses cerium oxide (CeO2), and the present invention uses aloxite (AI2O3) (Al2O3), the carbon of granularity #8000 or more
