Abstract
The invention provides a processing technique of a glass light guide plate. The processing technique includes the following steps that: a glass light guide plate is provided, wherein the glass light guide plate is provided with a first surface and a second surface opposite to the first surface; lattice points are marked on the first surface of the glass light guide plate through adopting a laser point marking mode; the first surface is washed through hydrofluoric acid; and the glass light guide plate is washed through water. The glass light guide plate with lattice points which is prepared through the processing technique has the advantages of no chromatic aberration, excellent lattice point effects, no crack, high glass strength, little possibility of being fractured and high light guide performance, and can be produced in a batch manner. With the processing technique adopted, lattice points of which the sizes are smaller than 0.1mm can be produced on the glass light guide plate. According to the glass light guide plate prepared through the processing technique of the invention, ink has little possibility of falling off from the glass light guide plate.
Description
[technical field]
The present invention relates to light guide plate technical field, particularly the manufacturing procedure of glass light guide plate.
[background technology]
Side-edge type backlight can use light guide plate to convert pointolite to area source, the material of current making light guide plate has polymethylmethacrylate (PMMA), copolymer of methyl methacrylatestyrene (MS) etc., and then makes site in the mode such as underrun printing, laser dotting of light guide plate.Recently be proposed a kind of light guide plate using glass substrate to make, the comparable macromolecule material of its hardness goes up by force tens times, and TV fuselage can also be made thinner.The light guide plate of glass material generally has two kinds of site production methods: a kind of for adopting the method for printing net-point, and its advantage is can mass production, and its shortcoming is: 1, because of ink and glass chemistry character variant, therefore easily produce aberration; 2: because the adhesion of ink is poor, therefore easily come off or part stripping; 3: for extra small site, as the site of below 0.1mm, cannot use the method for printing net-point, its production is poor.Another kind of for make site with laser dotting, but if glass light guide plate adopts the mode of laser dotting, around its site, have blind crack, due to glass easily embrittlement itself, so the intensity of glass can be affected, be unfavorable for the quality of product.Therefore need to look for a kind of glass light guide plate processing technology of above-mentioned defect problem of can avoiding to carry out alternative existing glass light guide plate process technology.
[summary of the invention]
The object of the present invention is to provide a kind of processing technology of glass light guide plate, solving glass light guide plate has crackle, easily embrittlement, poor product quality, is difficult to make below 0.1mm site, easily occur the problems such as aberration.
In order to solve the problem, the invention provides a kind of processing technology of glass light guide plate, it comprises:
There is provided glass light guide plate, described glass light guide plate has first surface and the second surface corresponding with described first surface;
Knit a net on the first surface of described glass light guide plate a little by the mode of laser dotting;
With first surface described in hydrofluoric acid clean;
Described glass light guide plate is rinsed with water.
As a preferred embodiment of the present invention, the mass percent of described hydrofluorite is 5-20%.
As a preferred embodiment of the present invention, the mass percent of described hydrofluorite is 10%.
Compared with prior art, glass light guide plate of the present invention the glass light guide plate no color differnece with site obtained by processing technology, without below the 0.1mm that comes off, can make site, site effect is good, flawless, strength of glass are good, not easily broken, light conductivity is better, can be mass.
[accompanying drawing explanation]
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein:
Fig. 1 is the processing technology process flow diagram in one embodiment of a kind of glass light guide plate of the application.
[embodiment]
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Refer to Fig. 1, Fig. 1 is the processing technology process flow diagram in one embodiment of a kind of glass light guide plate of the application.As shown in Figure 1, described method 100 comprises the steps.
Step 110, provides glass light guide plate, and described glass light guide plate has first surface and the second surface corresponding with described first surface.
Concrete, select glass light guide plate, described glass light guide plate has first surface and the second surface corresponding with described first surface, and namely described glass light guide plate has certain thickness glass plate.
Step 120, knits a net a little on the first surface of described glass light guide plate by the mode of laser dotting.
Concrete, adopt laser dotting machine to knit a net a little on the first surface of described glass light guide plate.Because laser dotting machine and using method thereof are known content, therefore do not repeat them here.By this step, the length of the blind crack of described screen dot peripheral is generally at about 10-20um, and the degree of depth of site generally can reach about 50um, and the described degree of depth can carry out regulable control according to need of production when laser dotting.
Step 130, with first surface described in hydrofluoric acid clean.
Concrete, preparation hydrofluorite, the mass concentration of described hydrofluorite is 10%, has the first surface of described site by hydrofluoric acid clean after step 120 technique, and in this step, the reaction equation of described hydrofluorite and glass light guide plate is as follows: 4HF+SiO
2=SiF
4+ 2H
2o, the object of this step is adopted to be remove the periphery blind crack of site, because the degree of depth of site generally can reach about 50um and can regulate, after therefore adopting hydrofluorite corrosion to remove crackle, even if the described site degree of depth removes 10-20um, effect of described site still exists; Separately crackle can also be controlled at less scope, such as 5-10um by selecting different laser dotting machines, to make the impact of process on site of removing crackle less.
Step 140, rinses described glass light guide plate with water.
Concrete, rinse out the hydrofluorite on described glass light guide plate surface with water, avoid continuing to produce chemical reaction.
What the those of ordinary skill in affiliated field should be understood that is, one of feature of the present invention or object are: this technology is by using hydrofluorite, remove the blind crack produced on glass light guide plate because of laser dotting and obtain glass light guide plate, described glass light guide plate have no color differnece, without below the 0.1mm that comes off, can make site, site effect is good, flawless, strength of glass are good, not easily broken, light conductivity better, the feature that can be mass.
It is pointed out that the scope be familiar with person skilled in art and any change that the specific embodiment of the present invention is done all do not departed to claims of the present invention.Correspondingly, the scope of claim of the present invention is also not limited only to previous embodiment.
