In step s 201, line of cut 20 is defined on glass substrate 100, and defined by line of cut 20 Go out multiple pieces of glass cover plate 10.
Glass substrate 100 is the monoblock large-area glass substrate via Sensor processing procedures, i.e. glass substrate 100 On be formed with sensor circuit.Touch-screen glass cover-plate of the glass substrate 100 for electronic installation, it is in particular a kind of OGS substrates, its stress layer depth are more than 35um.It is appreciated that glass substrate 100 can also be electricity CF (color filter) substrates of sub- communication device or TFT (Thin Film Transistor) substrate.
In the present embodiment, the concrete size according to multiple pieces of glass cover plate 10, enterprising in glass substrate 100 Row mixed composition, forms line of cut 20 between adjacent two pieces of glass cover-plates 10.
Specifically, silk-screen indigo plant film is covered in glass substrate 100, to protect the surface of the glass substrate 100; Trace line is formed on the silk-screen indigo plant film of glass substrate 100, glass substrate 100 is exposed, using the trace Trace defines line of cut 20;Multiple pieces of glass cover plate 10 is defined using line of cut 20.
Wherein, line of cut 20 includes the first interlaced line of cut 21 of bearing of trend and the second line of cut 23, Wherein the first line of cut 21 is interrupted in staggered place, to be divided into two-section line of cut 211, two-section line of cut 211 End points and the second line of cut 23 interval predeterminable range.In the present embodiment, the end of two-section line of cut 211 Point is 0.6-0.8 millimeters with the distance of the second line of cut 23.First line of cut 21 and the second line of cut 23 Crisscross to be mutually perpendicular to, the first line of cut 21 is transverse cut, and the second line of cut 23 is cut for longitudinal direction Secant.
In the present embodiment, the size of glass cover-plate 10 is 550 millimeters * 650 millimeters, glass substrate 100 A lateral edges on laid out in parallel have the glass cover-plate 10 of three pieces of longitudinal directions, it is relative another on glass substrate 100 On edge, left and right is placed with two pieces of horizontal glass cover-plates 10, shape between the glass cover-plate 10 of adjacent two pieces of longitudinal directions Into there is line of cut 20.Line of cut 20 is also formed between adjacent two pieces horizontal glass cover-plates 10.Arrange longitudinal direction The short side edge of three pieces of glass cover-plates 10 of cloth defines the 3rd line of cut 24, the glass cover-plate of laterally arrangement 10 long side edge defines the 4th line of cut 25, and the 3rd line of cut 24 is parallel with the 4th line of cut 25 and two The distance between person is more than 4 millimeters.It is appreciated that the quantity of the glass cover-plate 10 of longitudinal direction can be 3 pieces More than, the quantity of horizontal glass cover-plate 10 can also be more than two pieces.
In step S202, along 20 glass-cutting substrate 100 of line of cut, so as to glass substrate 100 is split Form multiple pieces of glass cover plate 10.
It is pre- when distance second line of cut 23 sides are cut to towards the second line of cut 23 along the first line of cut 21 If apart from when, stop cutting, then from the opposite side predeterminable range of the second line of cut of distance 23 along first Line of cut 21 continues cutting towards the direction away from the second line of cut 23.
Specifically, in the present embodiment, using break bar (not shown) along 20 glass-cutting substrate 100 of line of cut, When the end points that wherein cuts off secant 211 is cut to along the first line of cut 21, break bar leaves glass substrate 100 and cross the second line of cut 23, from another end points for cutting off secant 211 along the first line of cut continue into Row cuts, and the time that wherein break bar leaves glass substrate 100 is the 2-3 seconds.
Due to cutting when the first interlaced line of cut 21 of extension line and the second line of cut 23, the first cutting On line 21, staggeredly part is not cut with the second line of cut 23, carries out in staggered place so as to avoid Brought destruction is cut in the repetition of both direction, improves the cutting yield of glass cover-plate.The cutting method Laser cutting device need not be adopted, cutting cost is reduced.
It is appreciated that two crisscross lines of cut 20 can also be not interrupted, break bar is along the first cutting When line 21 is cut to 23 about 0.6-0.8 millimeters of the second line of cut of distance, break bar leaves glass substrate 100 and gets over The second line of cut 23 is crossed, from the second line of cut of distance 23 opposite sides about 0.6-0.8 millimeters along the first cutting Another secant 211 that cuts off of line 21 proceeds cutting.
It is appreciated that the first line of cut 21 can also be longitudinally cutting line, the second line of cut 23 is laterally to cut Secant.In addition, when glass cover-plate 20 is not rectangle, the first interlaced line of cut 21 is cut with second Secant 23 to intersect in length and breadth, and can not also be oblique at an angle.
It is appreciated that line of cut 20 can be formed on glass substrate 100 by etching mode, or It is virtual, not physical presence, and it is control that the operating path that line of cut 20 is converted into break bar is stored in In program.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more concrete and detailed, But therefore can not be construed as limiting the scope of the patent.It should be pointed out that for this area For those of ordinary skill, without departing from the inventive concept of the premise, some deformations can also be made and is changed Enter, these belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended power Profit requires to be defined.
