Description
Technical field
The present invention relates to a kind of tracing wheel, especially relate to the tracing wheel that gripping properties between a kind of blade tip and brittle base is good, the end face strength of rule brittle base can be made to promote.
Background technology
In the past, at display panels or organic electroluminescent (EL, electro luminescence) panel display board, the solar cell etc. such as panel manufacturing step in, be provided with the cut-out step of the brittle substrates such as female glass (mother glass) substrate.In above-mentioned cut-out step, one applies the load that conforms to all conditions such as the material of brittle base or thickness in the face of tracing wheel, one side makes tracing wheel rotate on the surface of brittle base and forms line, cut off brittle base by applying specific power to brittle base along line, thus manufacture single panel or glass substrate.
As these tracing wheels, generally use the tracing wheel (with reference to following patent documentation 1) being formed with V-shaped sword along discoid circumferential part of taking turns.When using the tracing wheel of this first precedent to form line on the glass substrate, the blade tip of tracing wheel is acted on and the surface of glass substrate that blade tip is abutted produces recoverable deformation by load, secondly, along with the increase of blade tip load, viscous deformation is produced in the abutting portion of tracing wheel, if blade tip load increases further, then can exceed the stone wall limit of viscous deformation and produce brittle rupture, thus on the thickness direction of glass substrate growth of vertical slight crack.
Now, make blade tip deeply become large to the degree of depth of glass baseplate surface by increasing blade tip load, large in order to the energy quantitative change producing vertical slight crack, therefore, the length of vertical slight crack is also elongated.But, if blade tip load exceedes a certain size, then can form longer vertical slight crack, but become state of saturation along the internal strain of the plastic deformation area of the line on the surface of glass substrate, thus the horizontal slight crack of generation and cause producing undesirable chip (cullet).
Therefore, as the tracing wheel that the generation of horizontal slight crack while forming longer vertical slight crack is less, known following tracing wheel, namely form V-shaped sword along discoid circumferential part of taking turns, and form the projection of level altitude or the groove (with reference to following patent documentation 2) of constant depth at the blade tip of V-shaped sword with fixed spacing.According to this tracing wheel, can apply when jut is connected to glass substrate to get impact ready, therefore, centered by the point cantact realized by projection is become, the stress produced in the surface direction of glass substrate during line is few compared with situation in the past, therefore, one side can produce the vertical slight crack of the extremely length running through the degree of thickness of slab at glass substrate and do not produce useless horizontal slight crack, one side is rule to glass substrate continuously.
The tracing wheel of following structure is also well known, namely formed in the mode becoming continuous print blade tip along the crestal line portion of discoid circumferential part V-shaped sword of taking turns in the same manner, and when forming line to glass substrate, the scarp forming surface of the sword immediately below blade tip, to the notch recesses of the depth direction of line, alternately forms thinner wall section and heavy section (with reference to following patent documentation 3) at the fore-end of V-shaped sword thus.
Herein, Fig. 5 and Fig. 6 is utilized to be described the tracing wheel that following patent documentation 3 discloses.In addition, Fig. 5 A is the side-view of the tracing wheel that following patent documentation 3 discloses, and Fig. 5 B is sectional view, and Fig. 5 C is frontview, and Fig. 5 D is to amplification view during glass substrate formation line.In addition, the figure of Fig. 6 A to be the figure of the effect of the thinner wall section of the tracing wheel shown in explanatory view 5, Fig. 6 B be effect that heavy section is described.
This tracing wheel 50 is formed with by the scarp 51 of the sword of V-shape the blade tip 51a becoming crestal line portion along the edge, periphery of discoid tracing wheel 50 without interruption continuously.In addition, be formed with through hole 52 at the central part of tracing wheel 50, the wheel pin (wheel pin) (omit diagram) becoming turning axle is inserted in this through hole 52, and tracing wheel 50 is taken turns bearing pin support rotation by this.
The scarp 51 of the sword immediately below blade tip 51a, is formed with the multiple notch recesses 53 when tracing wheel 50 pairs of glass substrates 54 (with reference to Fig. 5 D) form line towards the depth direction of this line S by proper methods such as electrodischarge machining(E.D.M.).In addition, in this tracing wheel 50, the blade tip side part 53a forming the face of notch recesses 53 is formed in the mode becoming the state parallel with forming the blade tip 51a in crestal line portion.
As shown in Figure 5 D, be formed in glass substrate 54 line S the common degree of depth, namely from the degree of depth of surface to blade tip 51a of glass substrate 54 be d1 (less than about 10 μm, be generally less than 5 μm) when, this notch recesses 53 is the scarp 51 at sword, the position d3 from the position d2 to the surface of recessing glass substrate 54 that recess blade tip 51a is defined as the scope of depression and is formed.In addition, the blade tip side part 53a forming the face of notch recesses 53 becomes in fact vertical configuration relation with the surface of glass substrate 54.As mentioned above, notch recesses 53 is formed by the blade tip 51a side on the scarp 51 at sword, thus the part being formed with notch recesses 53 becomes thinner wall section 51b, the part not being formed with notch recesses 53 becomes heavy section 51c, becomes and is alternately formed with thinner wall section 51b and heavy section 51c and the state being formed with blade tip 51a continuously.
When utilizing this tracing wheel 50 pairs of glass substrates 54 to form line, alternately repeat to rule by being formed in the thinner wall section 51b of the front of sword and heavy section 51c, one side makes the degree of depth of going deep into of blade tip 51a become large one side gradually and carry out ruling process till the blade tip 51a of tracing wheel 50 arrives the lower-most point of the thickness direction of glass substrate 54.
Under the state that the thinner wall section 51b of the front being formed in sword carries out line process, as shown in Figure 6A, dodge recess because notch recesses 53 becomes and do not contact with the scarp Sa of groove of line S, so become the state that all loads only concentrate on the leading section of blade tip 51a, thus effectively rule by thinner wall section 51b.In the line process undertaken by this thinner wall section 51b, because blade tip 51a is not contacted with the plastic deformation area along line S, so can suppress lower by the generation of internal strain, the generation of horizontal slight crack can be prevented, form more shallow vertical slight crack Sb in the bottom of line S.Now, heavy section 51c becomes the state being about to enter in line S.
If after the thinner wall section 51b being formed in the front of sword passes through, heavy section 51c enters in this line S, then the both sides of the front end of this heavy section 51c are contacted with the scarp Sa of the groove of line S, and blade tip load is all applied to the scarp Sa of this groove.Along with heavy section 51c enters further, as shown in Figure 6B, the scarp Sa of groove is squeezed and viscous deformation planarization.Now, because line S becomes the state expanded to the left and right, so vertical slight crack Sb is formed larger.In addition, heavy section 51c enter to the front by being formed in sword thinner wall section 51b and in the line S formed time, be connected to the form of the scarp Sa of the groove of line S owing to becoming this heavy section 51c, therefore become the state applying to get impact ready, thus promote the formation of vertical slight crack Sb.
Thus, because alternately repeating to rule by the thinner wall section 51b and heavy section 51c being formed in the front of sword, deeply deepening gradually thus to glass substrate 54, so can to form darker vertical slight crack Sb with the equal or blade tip load be less than in the past in the past.Its result, due to the load to glass substrate 54 applies can be made to reduce when ruling, so produce residual stress at glass substrate 54 hardly, thus plays the effect that can suppress the generation of horizontal slight crack.

Embodiment
Below, utilize and graphic embodiments of the present invention to be described.But embodiment shown below represents an example of the tracing wheel making technological thought of the present invention specialize, be not intended to by the present invention specifically for this tracing wheel, also similarly can be applicable to the tracing wheel of other embodiments comprised in the scope of claim.In addition, shown below graphic in, in order to identify each formation easy understand, suitably make scale different for each component part, may not illustrate according to the size of reality or angle.
First, be described with reference to the tracing wheel of Fig. 1 ~ Fig. 3 to embodiment.In addition, Fig. 1 is the side-view of the tracing wheel of embodiment.Fig. 2 is the frontview of the tracing wheel of Fig. 1.Fig. 3 is the amplification view of the III-III line along Fig. 1.
As shown in FIG. 1 to 3, the tracing wheel 10 of embodiment has the shape throughout being formed with V-shaped sword along the all-round of discoid circumferential part of taking turns.In more detail, there is the shape configured in the mode of the bottom surface of the area of bottom surface 2 frustums of a cone large compared with upper bottom surface subtend each other, there is abacus bead shape, and comprise main part 11, the scarp 12 of sword and the blade tip 12a as crestal line portion that formed by the scarp of sword.
In addition, this tracing wheel 10 suitably can be coated with the component of single-crystal diamond, polycrystalline diamond, CBN etc. by choice for use by physical vaporous deposition or chemical Vapor deposition process on the surface of cemented carbide, sintered diamond system or steel or superhard alloy.
As shown in Figures 1 and 2, main part 11 is formed as discoid, at the immediate vicinity of main part 11, is provided with the through hole 10a running through main part 11 along turning axle 10b.In addition, the scarp 12 of sword is annularly provided with at the periphery of main part 11 circle.
As shown in Figure 1, the scarp 12 of sword is the circular body formed by the inner circumferential of the concentric circles centered by turning axle 10b and periphery.In addition, as shown in Figure 2, the scarp 12 of sword is V shape under forward sight.Thickness along the scarp 12 of the sword of turning axle 10b reduces towards blade tip 12a gradually along with from turning axle 10b side.Blade tip 12a is arranged along the outermost perimembranous on the scarp 12 of sword.In addition, in the same manner as first precedent, the scarp 12 of sword is formed by gradient polishing (using the face of grinding stone to carry out grinding and to form the method on scarp).
And the tracing wheel 10 of present embodiment is the notch recesses 13 of multiple same shape is equally spaced formed in sword scarp 12 in concentric circles.In addition, in Fig. 1 and Fig. 2, for ease of drawing, only illustrate several notch recesses 13 respectively.This notch recesses 13 is less due to size, so in order to process accurately, is formed by laser processing method.In addition, it not is same shape entirely that notch recesses 13 may also be, and also can not be at equal intervals, in addition, also can lay respectively at different positions on the two sides on the scarp of sword.
In addition, because notch recesses 13 also comprises the situation that the face 13a (reference Fig. 3) forming notch recesses 13 is curved surface, therefore, the angle between the tangent plane on the scarp 12 of tangent plane L that form the position that face 13a that the angle θ 2 between the blade tip side part of face 13a of notch recesses and the scarp 12 of sword is defined as being formed notch recesses intersects with the scarp 12 of sword in the part of blade tip side, that be formed in the face forming notch recesses and sword.
The mode that each notch recesses 13 becomes b/a < 1 with the length a of the bearing of trend on the scarp 12 along sword and the ratio b/a of the length b along the direction orthogonal with the scarp 12 of sword is formed as elliptical shape, in Fig. 1 and Fig. 2, illustrate the example of the oblong shape being set to b/a < less than 0.5.In the same manner as the content shown in above-mentioned patent documentation 3, the plurality of notch recesses 13 when be formed in glass substrate 14 (with reference to Fig. 4) line S the common degree of depth, be namely d1 (less than about 5 μm) from the degree of depth of surface to blade tip 12a of glass substrate 14, the position d3 from the position d2 to the surface of recessing glass substrate 14 that recess blade tip 12a is defined as the scope of depression by the scarp 12 of sword and is formed.
In addition, notch recesses 13 is formed from the be separated by position of specific range of blade tip 12a on the scarp 12 of V-shaped sword, notch recesses 13 is formed by the blade tip 12a side on the scarp 12 at sword, and make the part being formed with notch recesses 13 become thinner wall section 12b, the part not being formed with notch recesses 13 becomes heavy section 12c, thus becomes and be alternately formed with thinner wall section 12b and heavy section 12c at the fore-end of V-shaped sword and be formed with the state of blade tip 12a continuously.
And, the tracing wheel of present embodiment is different from the tracing wheel shown in above-mentioned patent documentation 3, as shown in Figure 3, the angle of blade tip 12a is being set to θ 1 by notch recesses 13, and when the angle formed between the blade tip side part in the face of notch recesses 13 and the scarp 12 of sword is set to θ 2, formed in the mode of 180 ° of > θ 2 > 180 °-(θ 1)/2.
This θ 2 is stipulators as follows.That is, when θ 2=180 ° for not being formed with the state of notch recesses, and with as above-mentioned patent documentation 1 the tracing wheel being formed with V-shaped sword along discoid circumferential part of taking turns that discloses be same shape.In this case, by increasing blade tip load, and make the degree of depth change of blade tip 12a deeply to the surface of glass substrate 14 large, and it is large in order to the energy quantitative change producing vertical slight crack, therefore, the degree of depth of vertical slight crack also becomes large, if but blade tip load exceedes a certain size, then and can produce horizontal slight crack thus produce more undesirable cullet.
On the other hand, when θ 2=180 °-(θ 1)/2, with as above-mentioned patent documentation 3 the blade tip side part in the face of formation notch recesses 13 that the discloses state parallel with the blade tip 12a forming crestal line portion be same shape.That is, the blade tip side part forming the face of notch recesses 13 becomes in fact vertical configuration relation with the surface of glass substrate 14.In this case, the state of impact is applied to get ready when heavy section 12c enters in the line of the thinner wall section 12b formation of the front by being formed in sword owing to becoming, so promote the formation of vertical slight crack.
Its result, owing to can make to reduce the load that glass substrate 14 applies during line, so produce residual stress hardly at glass substrate 14, and the generation of horizontal slight crack can be suppressed, therefore, can obtain at the glass substrate carrying out to produce at end face when cutting off process concavo-convex height shaping quality.Otherwise, time in the line that the thinner wall section 12b entering to the front by being formed in sword due to heavy section 12c is formed to get impact ready comparatively large, so end face strength can reduce.
Therefore, in the present embodiment, in order to become the state being formed with notch recesses 13 and the condition adopting 180 ° of > θ 2, in addition, getting ready time in the line formed in order to the thinner wall section 12b not making heavy section 12c enter to the front by being formed in sword is impacted excessive and adopts the condition of θ 2 > 180 °-(θ 1)/2.
Fig. 4 is utilized to be described the effect using tracing wheel 10 pairs of glass substrates 14 of present embodiment to be formed when ruling S.In addition, the figure of Fig. 4 A to be the figure of the effect of the thinner wall section of the tracing wheel that embodiment is described, Fig. 4 B be effect that heavy section is described.
In the same manner as the situation of the tracing wheel disclosed with the above-mentioned patent documentation 3 shown in Fig. 6, alternately repeatedly rule by the thinner wall section 12b and heavy section 12c that are formed in the front of sword, until the tracing wheel 10 of embodiment blade tip 12a arrive be set in the thickness direction of glass substrate 14 go deep into the degree of depth till.
And, under the state that the thinner wall section 12b of the front being formed in sword carries out line process, as shown in Figure 4 A, although notch recesses 13 contacts with the scarp Sa of the groove of line S, but become the state that all loads only concentrate on the leading section of blade tip 12a, thus effectively rule by thinner wall section 12b.In the line process undertaken by this thinner wall section 12b, even if blade tip 12a touches the plastic deformation area along line S, also can the generation of internal strain be suppressed lower, and the generation of horizontal slight crack can be prevented, form more shallow vertical slight crack Sc in the bottom of line S.Now, heavy section 12c becomes the state being about to enter in line S.
If after the thinner wall section 12b being formed in the front of sword passes through, heavy section 12c enters in this line S, then the both sides of the front end of this heavy section 12c contact with the scarp Sa of the groove of line S, and blade tip load is all applied to the scarp Sa of this groove.Along with heavy section 12c enters further, as shown in Figure 4 B, the scarp Sa of groove is squeezed and viscous deformation planarization.Now, because line S becomes the state expanded to the left and right, so vertical slight crack Sc is formed larger, and, owing to becoming the form that this heavy section 12c abuts with the scarp Sa of the groove of line S, therefore promote the formation of vertical slight crack Sc.
Thus, alternately repeatedly rule by the thinner wall section 12b and heavy section 12c being formed in the front of sword, can to form vertical slight crack Sc with the equal or blade tip load be less than in the past in the past.Its result, due to the load being applied to glass substrate 14 can be made to reduce when ruling, so produce residual stress at glass substrate 14 hardly, thus can suppress the generation of horizontal slight crack.
In addition, in the tracing wheel 10 of present embodiment, owing to meeting the condition of θ 2 > 180 °-(θ 1)/2 between blade tip angle θ 1 and the angle θ 2 being formed between the blade tip side part in face of notch recesses 13 and the scarp 12 of sword, so little compared with the situation of impacting the tracing wheel disclosed with the above-mentioned patent documentation 3 being set to θ 2=180 °-(θ 1)/2 by getting ready of carrying out of the heavy section 12c of the front being formed in sword.
Therefore, tracing wheel 10 according to the present embodiment, the not easily horizontal slight crack of generation compared with the tracing wheel disclosed with above-mentioned patent documentation 1, compared with the tracing wheel disclosed with above-mentioned patent documentation 3, vertical slight crack is more shallow, and in the same manner as the tracing wheel that above-mentioned patent documentation 3 discloses, the gripping properties between the brittle base such as blade tip and glass substrate is good.And, because vertical slight crack is more shallow, so the end face strength of rule brittle base can be made to promote, even and if just like with other situations as intersecting of ruling, also not easily cross part produce breach.
In addition, in the tracing wheel 10 of present embodiment, between blade tip angle θ 1 and the angle θ 2 being formed between the blade tip side part in face of notch recesses 13 and the scarp 12 of sword, preferably 175 ° >=θ 2 >=180 °-(θ 1)/2+5 °, more preferably 175 ° >=θ 2 >=180 °-(θ 1)/2+45 °.
When θ 2 is the condition of 180 ° of > θ 2 > 175 °, form the effect of notch recesses 13 less, and the difference do not told between the tracing wheel disclosed at tracing wheel and the above-mentioned patent documentation 1 of present embodiment in fact.In addition, when θ 2 is the condition of 180 °-(θ 1)/2+5 ° of > θ, 2 >=180 °-(θ 1)/2, the difference do not told between the tracing wheel disclosed at tracing wheel and the above-mentioned patent documentation 3 of present embodiment in fact.When θ 2 is the condition of 175 ° >=θ 2 >=180 °-(θ 1)/2+45 °, because vertical slight crack can not become deeply, so the end face strength of rule brittle base can be promoted further.
In addition, the scope of the preferred 1 ~ 5mm of the outer diameter D (with reference to Fig. 2) of tracing wheel 10.When the outer diameter D of tracing wheel 10 is less than 1mm, the operability of tracing wheel 10 and weather resistance reduce, and industrial production also becomes difficulty.On the other hand, when the outer diameter D of tracing wheel 10 is greater than 5mm, there is the tendency not easily forming line with lower load in suitable load range deflection high load side during line.
In addition, the scope of the preferred 0.5 ~ 1.2mm of the thickness T of tracing wheel 10.When the thickness T of tracing wheel 10 is less than 0.5mm, there is the situation of processibility and operability reduction.On the other hand, when the thickness T of tracing wheel 10 is greater than 1.2mm, the cost needed for the manufacture of tracing wheel 10 uprises.
In addition, the blade tip angle θ 1 of blade tip 12a is generally obtuse angle, preferably the scope of 165 ° >=θ > 90 °.In addition, the concrete angle of blade tip angle θ 1 is material or thickness etc. according to the brittle substrate that will cut off and suitably sets.In addition, as long as the best forming position of this notch recesses 13 considers the material of brittle substrate and thickness, the blade tip angle θ 1 of tracing wheel and thickness, and suitably set being less than experimentally in the scope of the degree of depth of surface to blade tip 12a from brittle base during line, the scope of about 1 ~ 5 μm.In addition, there is not critically limit in the spacing between adjacent notch recesses 13, suitably selects in the scope of 20 ~ 200 μm.In addition, if sum up the tracing wheel of above-mentioned embodiment, the difference of the characteristic of tracing wheel (first precedent 2) that tracing wheel (first precedent 1) that above-mentioned patent documentation 1 discloses, above-mentioned patent documentation 3 disclose, then described in following table 1.
[table 1]
| Tracing wheel | Longer vertical slight crack | End face strength | Gripping properties |
| Example | × | ○ | ○ |
| First precedent 1 | × | ◎ | × |
| First precedent 2 | ○ | × | ○ |
In addition, in the tracing wheel 10 of above-mentioned embodiment, the notch recesses 13 illustrating same shape is circumferentially equally spaced formed with multiple examples same, but in the present invention, even if the different notch recesses 13 of shape is formed with single or multiple at same circumferentially non-uniform distantance or stagger, also corresponding effect can be played.But, if the notch recesses 13 of same shape same be circumferentially equally spaced formed multiple, the line of homogeneous then can be formed throughout total length, and because the contact condition of the tracing wheel abutted with brittle bases such as glass substrates on end is homogeneous in fact, so the end face strength of rule brittle base can be promoted further, even and if just like with other situations as intersecting of ruling, also more not easily cross part produce breach.
In the tracing wheel 10 of above-mentioned embodiment, the length a illustrating the bearing of trend on the scarp 12 along sword as notch recesses 13 and the ratio b/a of the length b along the direction orthogonal with the scarp 12 of sword are the elliptoid example of length of b/a < 0.5.But, in the present invention, as notch recesses 13, even if be the condition of b/a >=1, also corresponding effect can be played, if but at least meet the condition of b/a < 1, then the shape of notch recesses 13 becomes ellipticity, and becomes the state along the direction proper alignment orthogonal with the scarp 12 of sword, therefore, can form multiple notch recesses 13 on the scarp 12 of sword, the end surface shape of the brittle base of ruling becomes more homogeneous, and end face strength can be made to promote further.
