Embodiment
For the ease of understanding the present invention, the below is described more fully the present invention with reference to relevant drawings.Provided preferred embodiment of the present invention in the accompanying drawing.But the present invention can realize with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present invention more comprehensively thorough.
Need to prove that when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have simultaneously centering elements.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to the common understanding of those skilled in the art of the present invention with scientific terminology.Employed term is not intended to be restriction the present invention just in order to describe the purpose of specific embodiment in instructions of the present invention herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
As shown in Figure 1, the touch-screen of an embodiment comprises side 110 and relative first surface 120 and second surface (not shown) with tempered glass 100.Wherein, side 110 is provided with the groove 112 that is intervally arranged, and groove 112 is used for increasing the area of side 112.
The inwall of groove 112 can be curve form, and in the present embodiment, it is planar that the inwall of groove 112 is circular arc.And when constancy of volume, inwall is the area that the planar groove of circular arc 112 can farthest increase side 110.On the whole, side 110 is the circular arc zigzag.
Touch-screen is usually relatively thin with tempered glass 100, and for the ease of 110 groove 112 being set in the side, in the present embodiment, groove 112 runs through first surface 120 and second surface, and groove 112 and first surface 120 and second surface approximate vertical.And to be circular arc planar the part side 110 between adjacent two grooves 112, thereby so that side 110 presents circular-arc along one party to fluctuation, further increase the area of side 110.Groove 112 is more conducive to processing with first surface 120 and second surface approximate vertical.Be appreciated that in other embodiments groove 112 also can become with first surface 120 and second surface 30 degree angles, miter angle, 60 degree angles etc., groove 112 can increase touch-screen and use side 110 areas of tempered glass 100 to get final product.Part side 110 between adjacent two grooves 112 also can be plane.
In the present embodiment, the groove depth of groove 112 is 0.2～0.25 millimeter, and the A/F of groove 112 on side 110 is 0.15～0.2 millimeter.Groove 112 occupies the volume less that touch-screen is used tempered glass 100, thereby so that groove 112 does not affect touch-screen tempered glass 100 overall configurations.
As shown in Figure 2, in other embodiments, groove 212 also can be around touch-screen tempered glass 200, and namely groove 212 with 200 1 weeks of tempered glass, is processed more convenient around touch-screen.Because touch-screen is usually relatively thin with tempered glass 200, the groove depth of groove 212 is preferably 0.05～0.1 millimeter, the A/F of groove 212 on side 210 is 0.05～0.1 millimeter, simultaneously the number of the groove 112 of the number of the groove 212 among Fig. 2 in Fig. 1.
Above-mentioned touch-screen is provided with for the groove 112 that increases lateralarea with the side 110 of tempered glass 100, thereby so that touch-screen can form enough stress in its side 110 with tempered glass 100, and then so that touch-screen has higher intensity with tempered glass 100 integral body, thereby above-mentioned touch-screen has higher quality with tempered glass 100.
As shown in Figure 3, present embodiment also provides the method for making of a kind of touch-screen with tempered glass, comprises the steps:
Step 310 is fixed on glass baseplate to be processed on the deck of muller.
In the present embodiment, glass baseplate to be processed conforms to the size of the touch-screen of need producing with tempered glass, directly is fixed on the deck of muller to get final product.In other embodiments, when glass baseplate to be processed is large plate substrate, need first large plate substrate to be processed into touch-screen with the small pieces glass baseplate that the size of tempered glass conforms to, again the small pieces base material is fixed on the deck of muller as glass baseplate to be processed.
Step 320 imports grinding track in the muller, and loads onto the grinding rod that is complementary with grinding track at muller.
Grinding rod and grinding track determine the arranging and size on the side of glass baseplate of groove.
Adopt the cylindrical grinding rod, grind according to grinding track shown in Figure 4 400, obtain touch-screen tempered glass 100 as shown in Figure 1.
Adopt grinding rod 500 as shown in Figure 5, grinding rod 500 is provided with a plurality of abrasive wheels that are intervally arranged 510, the thickness of abrasive wheel 510 increases to pars intermedia gradually from edge part, grinds according to grinding track shown in Figure 6 600, obtains touch-screen tempered glass 200 as shown in Figure 2.
Step 330 starts muller, and grinding rod grinds the side of glass baseplate according to grinding track, obtains the glass intermediate that the side is provided with the groove that is intervally arranged.
Step 340 is carried out intensive treatment to the glass intermediate, namely obtains the touch-screen tempered glass.
In the present embodiment, before the glass intermediate is carried out intensive treatment, also comprise the step that the glass intermediate is cleaned.
The detailed process of intensive treatment is, the glass intermediate put into potassium nitrate solution carry out ion-exchange, with the sodion on the potassium ion instead of glass intermediate outside surface, realizes the reinforcement to the glass intermediate.
Above-mentioned touch-screen is simple with operation and the equipment of the method for making of tempered glass, is fit to industrialization production, and can obtain by changing grinding rod the groove of various shapes, to meet the different needs.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
