Description

本発明は、脆性材料基板をスクライブするためのスクライビングホイールを保持するチップホルダユニットに関する。   The present invention relates to a chip holder unit that holds a scribing wheel for scribing a brittle material substrate.

脆性材料基板を所望の寸法にスクライブし、分断するためスクライブ装置が用いられる。スクライブ装置は、脆性材料基板と対向するスクライブヘッドにチップホルダユニットを備えている。図１は、従来のチップホルダユニットの側面図である。チップホルダユニット１００は、チップホルダ１１０、スクライビングホイール１２０、及びピン１３０を有し、チップホルダにスクライビングホイールを取り付けたものである。   A scribing device is used for scribing and dividing the brittle material substrate to a desired dimension. The scribing device includes a chip holder unit on a scribing head facing the brittle material substrate. FIG. 1 is a side view of a conventional chip holder unit. The chip holder unit 100 includes a chip holder 110, a scribing wheel 120, and a pin 130, and the scribing wheel is attached to the chip holder.

図１に示すようにチップホルダ１１０の下部には、ホルダ溝１１１及びピン孔１１２が形成されている。スクライビングホイール１２０は円板状の部材であり、２つの円形の側面の中心を貫通する貫通孔を有し、スクライビングホイール１２０の外周部に沿ったＶ字形の刃を有する。Ｖ字形の刃先は、スクライビングホイール１２０の外周に沿った稜線を形成している。稜線の両側の傾斜面（外周辺部）は、通常、９０〜１６０°の角度（収束角）で相互に交差し稜線を形成する。ピン１３０は円柱形の部材であり、スクライビングホイール１２０の貫通孔及びホルダ１１０のピン孔１１２に挿入されて、スクライビングホイール１２０を回転自在に保持するものである。   As shown in FIG. 1, a holder groove 111 and a pin hole 112 are formed in the lower part of the chip holder 110. The scribing wheel 120 is a disk-shaped member, has a through-hole penetrating the center of two circular side surfaces, and has a V-shaped blade along the outer periphery of the scribing wheel 120. The V-shaped cutting edge forms a ridge line along the outer periphery of the scribing wheel 120. The inclined surfaces (outer peripheral portions) on both sides of the ridge line usually intersect with each other at an angle (convergence angle) of 90 to 160 ° to form a ridge line. The pin 130 is a cylindrical member, and is inserted into the through hole of the scribing wheel 120 and the pin hole 112 of the holder 110 to hold the scribing wheel 120 rotatably.

チップホルダ１００は、ピン１３０を用いてスクライビングホイール１２０をホルダ溝１１１内で保持し、図示しない軸押さえカバーにより保持している。このようなチップホルダユニットを備えるスクライブ装置として、特許文献１に示すものがある。   The chip holder 100 holds the scribing wheel 120 in the holder groove 111 using pins 130 and holds it by a shaft pressing cover (not shown). There exists a thing shown in patent document 1 as a scribe apparatus provided with such a chip holder unit.

国際特許公開 ＷＯ２００７／０６３９７９号公報International Patent Publication No. WO2007 / 063979

スクライビングホイールの厚さｄは例えば０．６５ｍｍ程度であり、公差は例えば−５〜１５μｍである。一方ホルダ溝の幅ｗはスクライビングホイールの厚さｄに対応して例えば０．６５ｍｍであり、公差は０〜＋２０μｍである。この公差によりスクライビングホイールとホルダ溝との間にはわずかのクリアランスが確保されている。このクリアランスにより、スクライビングホイールはホルダ溝内でピンの軸方向に公差の差に相当する分、例えば５〜３５μｍ程度軸方向に移動することができる。しかしクリアランスが設けられているため、基板をスクライブしたときにスクライブラインの直線性が悪くなる場合があり、最大で約３５μｍのふらつきが生じる原因となっていた。   The thickness d of the scribing wheel is, for example, about 0.65 mm, and the tolerance is, for example, −5 to 15 μm. On the other hand, the width w of the holder groove is, for example, 0.65 mm corresponding to the thickness d of the scribing wheel, and the tolerance is 0 to +20 μm. This tolerance ensures a slight clearance between the scribing wheel and the holder groove. By this clearance, the scribing wheel can move in the axial direction by about 5 to 35 μm, for example, corresponding to the difference in tolerance in the axial direction of the pin in the holder groove. However, since the clearance is provided, the linearity of the scribe line may be deteriorated when the substrate is scribed, which causes the maximum wobbling of about 35 μm.

この問題は、スクライビングホイールの厚さやホルダ溝の幅の公差をより小さくすれば解決されるが、実際にはこれらの公差を更に小さくすることは難しく、製造価格が上昇してしまうという問題点がある。また公差が小さすぎればスクライビングホイールをホルダ溝に挿入し難くなるという問題点も生じる。   This problem can be solved by making the tolerance of the scribing wheel thickness and the width of the holder groove smaller, but in reality, it is difficult to make these tolerances even smaller, and the manufacturing price increases. is there. Further, if the tolerance is too small, there is a problem that it becomes difficult to insert the scribing wheel into the holder groove.

本発明は、このような従来のスクライブ装置において、スクライブラインの直線性を向上させるためになされたものであって、スクライビングホイールの保持位置を安定させ、直線性を向上させることを目的とする。   The present invention has been made to improve the linearity of the scribe line in such a conventional scribing device, and aims to stabilize the holding position of the scribing wheel and improve the linearity.

この課題を解決するために、本発明のチップホルダユニットは、円板状であって中心に貫通孔を有し、円板外周部に沿ってＶ字形の稜線をなす刃先を形成する２つの曲面を有するスクライビングホイールと、互いに平行な対向する面を有する一対の支持部の間に前記スクライビングホイールを挿入するための一定の幅を持つホルダ溝、前記一対の支持部を同軸に貫通するピン孔、及び前記ピン孔及び前記スクライビングホイールの貫通孔に挿入され、前記ホルダ溝内で前記スクライビングホイールを回転自在に保持するピンを有するホルダと、を具備するチップホルダユニットにおいて、前記ホルダの一対の支持部に同軸に形成され、支持部の一方に貫通孔、他方にねじ溝を有する間隔調整孔と、前記間隔調整孔の貫通孔より挿入され、前記ホルダ溝と前記スクライビングホイールとの間隔を調整する調整ねじと、を有するものである。   In order to solve this problem, the chip holder unit of the present invention has a disk shape, a through hole in the center, and two curved surfaces that form a cutting edge that forms a V-shaped ridge line along the outer periphery of the disk. A holder groove having a certain width for inserting the scribing wheel between a pair of support portions having opposing surfaces parallel to each other, a pin hole coaxially penetrating the pair of support portions, And a holder having a pin that is inserted into the pin hole and the through hole of the scribing wheel and rotatably holds the scribing wheel in the holder groove, and a pair of support portions of the holder Are formed coaxially with each other, inserted through a through hole of the gap adjusting hole, a gap adjusting hole having a through hole on one side of the support portion and a thread groove on the other side, An adjusting screw for adjusting the distance between the holder groove and the scribing wheel, and has a.

ここで前記ホルダの一方の支持部に形成された第２のねじ溝と、前記第２のねじ溝に挿入され、前記一対の支持部のうち他方の支持部の内壁に接してホルダ溝の間隔を所定値以上に保つ締付防止ねじと、を有するようにしてもよい。   Here, a second screw groove formed in one support part of the holder and an interval between the holder grooves in contact with the inner wall of the other support part of the pair of support parts, inserted into the second screw groove. And a tightening prevention screw that keeps the value above a predetermined value.

このような特徴を有する本発明によれば、スクライビングホイールを保持する位置を安定させることができ、脆性材料基板上に形成するスクライブラインの直線性を向上させることができる。   According to the present invention having such characteristics, the position where the scribing wheel is held can be stabilized, and the linearity of the scribe line formed on the brittle material substrate can be improved.

（第１の実施の形態）
本発明の実施の形態によるチップホルダユニットについて図面を用いて説明する。図２はチップホルダユニットの正面図である。チップホルダユニット１はチップホルダ１０とスクライビングホイール３０を有しており、チップホルダ１０の下端にスクライビングホイール３０を回転自在に保持するものである。チップホルダ１０は図３，図４，図５に示すように、下方が三角形状に形成された直方体状の部材であり、上部にチップホルダ１０を固定するための貫通孔１１を有している。チップホルダ１０の下方には三角形状のホルダ溝１２が下方を開放するように形成され、ホルダ溝１２を挟むこの三角形状の部分を支持部１３，１４とする。チップホルダ１０の支持部１３，１４の相対向する面はほぼ平行に形成され、ホルダ溝１２の間隔ｗはスクライビングホイール３０の幅よりわずかに大きくなるようにしておく。ホルダ溝１２の幅は例えば約０．６７ｍｍとする。 (First embodiment)
A chip holder unit according to an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a front view of the chip holder unit. The chip holder unit 1 has a chip holder 10 and a scribing wheel 30. The scribing wheel 30 is rotatably held at the lower end of the chip holder 10. As shown in FIGS. 3, 4, and 5, the chip holder 10 is a rectangular parallelepiped member formed in a triangular shape on the lower side, and has a through hole 11 for fixing the chip holder 10 on the upper part. . A triangular holder groove 12 is formed below the chip holder 10 so as to open downward, and the triangular portions sandwiching the holder groove 12 are referred to as support portions 13 and 14. The opposing surfaces of the support portions 13 and 14 of the chip holder 10 are formed substantially in parallel, and the interval w between the holder grooves 12 is set to be slightly larger than the width of the scribing wheel 30. The width of the holder groove 12 is about 0.67 mm, for example.

左右の支持部１３，１４の最下端には支持部１３，１４を夫々貫通するピン孔１５，１６が同軸に形成される。ピン孔１５，１６はホルダ溝１２と垂直に交差しており、スクライビングホイール３０のピンを保持する円形の貫通孔である。これらのピン孔の上部には支持部１３側で内径がホルダ溝１２側で小さく、外側で大きい貫通孔１７が形成され、支持部１４にはこれと同軸のねじ溝１８が形成されており、これらを間隔調整孔とする。間隔調整孔はホルダ溝１２の間隔ｗを微調整するものである。   Pin holes 15 and 16 penetrating the support portions 13 and 14 are formed coaxially at the lowermost ends of the left and right support portions 13 and 14, respectively. The pin holes 15 and 16 intersect the holder groove 12 perpendicularly and are circular through holes that hold the pins of the scribing wheel 30. At the upper part of these pin holes, a through hole 17 having a small inner diameter at the support groove 13 side and a large outer diameter at the holder groove 12 side is formed, and a screw groove 18 coaxial with this is formed in the support section 14. These are referred to as interval adjusting holes. The interval adjusting hole is used to finely adjust the interval w of the holder groove 12.

又図３に示すようにこのねじ溝の左側方には支持部１４にねじ溝１９が設けられる。支持部１３にも同様のねじ溝（図示せず）が設けられている。これらのねじ溝は軸押さえカバー２１，２２を取付けてピンを脱落しないように保持するものである。軸押さえカバー２１，２２は図２に示すように一端が突出したワッシャ形状を有している。   As shown in FIG. 3, a screw groove 19 is provided in the support portion 14 on the left side of the screw groove. A similar thread groove (not shown) is also provided in the support portion 13. These screw grooves are for holding the shaft pressing covers 21 and 22 so as not to drop the pins. As shown in FIG. 2, the shaft pressing covers 21 and 22 have a washer shape with one end protruding.

スクライビングホイール３０は、例えば焼結ダイヤモンドで形成された、例えば厚さｄが約０．６５ｍｍの円板状の部材であって、中心に貫通孔を有している。またスクライビングホイール３０は、外周部に沿って稜線を形成するＶ字形の刃を有している。稜線の両側の傾斜面（外周辺部）は、通常、９０〜１６０°の角度（収束角）で相互に交差し稜線を形成する。ピン３１は、例えば、超硬合金等の金属、焼結ダイヤモンドで形成された円柱形の部材であって、一端が尖頭形状を有している。   The scribing wheel 30 is a disk-shaped member made of, for example, sintered diamond and having a thickness d of about 0.65 mm, for example, and has a through hole at the center. The scribing wheel 30 has a V-shaped blade that forms a ridge line along the outer periphery. The inclined surfaces (outer peripheral portions) on both sides of the ridge line usually intersect with each other at an angle (convergence angle) of 90 to 160 ° to form a ridge line. The pin 31 is, for example, a cylindrical member formed of a metal such as cemented carbide or sintered diamond, and one end has a pointed shape.

次にこの実施の形態によるチップホルダユニットの組立てについて説明する。まず図６に示すように貫通孔１７より調整ねじ２３を挿入し、ねじ溝１８と噛合させる。この時点では調整ねじ２３は締め込まないでおく。次に支持部１３側より軸押さえカバー２１をねじ２４によって取付け、ピン孔１５の一端を閉じる。次いでスクライビングホイール３０をホルダ溝１２内に挿入して保持し、ピン３１を尖頭形状の部分からピン孔１６、及びスクライビングホイール３０の貫通孔、ピン孔１５に挿入する。ピン３１の尖頭形状の部分が、ピン孔１５の一方の開口付近にある軸押さえカバー２１と接するところまでピン３１を挿入し、図７に示すように軸押さえカバー２２をねじ２５でねじ止めしてピン孔１６の左端を閉じる。これによってピン３１はピン孔から脱落することはなく、スクライビングホイール３０はピン３１に回転自在に保持される。   Next, the assembly of the chip holder unit according to this embodiment will be described. First, as shown in FIG. 6, the adjusting screw 23 is inserted from the through hole 17 and engaged with the screw groove 18. At this time, the adjusting screw 23 is not tightened. Next, the shaft pressing cover 21 is attached by screws 24 from the support portion 13 side, and one end of the pin hole 15 is closed. Next, the scribing wheel 30 is inserted and held in the holder groove 12, and the pin 31 is inserted into the pin hole 16, the through hole of the scribing wheel 30, and the pin hole 15 from the pointed portion. The pin 31 is inserted until the pointed portion of the pin 31 is in contact with the shaft pressing cover 21 in the vicinity of one opening of the pin hole 15, and the shaft pressing cover 22 is screwed with the screw 25 as shown in FIG. Then, the left end of the pin hole 16 is closed. As a result, the pin 31 does not fall out of the pin hole, and the scribing wheel 30 is rotatably held by the pin 31.

このときチップホルダのホルダ溝１２とスクライビングホイール３０とは、前述したようにクリアランスにばらつきが生じている。このため間隔調整孔に挿入する調整ねじ２３によってその間隔を調整する。調整ねじ２３の調整については、スクライブしつつ調整ねじを徐々に締め付けていき、回転抵抗が増加し始める直前に設定することが考えられる。又あらかじめ製品状態のホルダ溝の幅ｗ及びスクライビングホイール３０の厚さｄを測定しておき、所望の幅となるように平面にホルダ１０をおいて上部よりねじで締め付け、所定寸法となるように設定してもよい。又スクライビングホイールを取付けた状態で調整ねじ２３を締め付けが最大限可能な位置まで締め付け、所定角度又は所定回転数戻すことによって所望のクリアランスを設定するようにしてもよい。   At this time, the clearance between the holder groove 12 of the chip holder and the scribing wheel 30 varies as described above. Therefore, the interval is adjusted by the adjusting screw 23 inserted into the interval adjusting hole. Regarding the adjustment of the adjusting screw 23, it is conceivable that the adjusting screw is gradually tightened while scribing and set immediately before the rotation resistance starts to increase. In addition, the width w of the holder groove in the product state and the thickness d of the scribing wheel 30 are measured in advance, and the holder 10 is placed on a flat surface so as to have a desired width, and is tightened with screws from the top so that a predetermined dimension is obtained. It may be set. Alternatively, a desired clearance may be set by tightening the adjusting screw 23 to a position where the tightening can be maximized with the scribing wheel attached, and returning the angle by a predetermined angle or a predetermined number of rotations.

こうしてクリアランスを最適値、例えば２μｍの間隔とすることができる。この状態でスクライブすれば、スクライビングホイール３０はホルダ溝１２内での位置が安定するので、スクライビングホイール３０の進行方向に対する左右のぶれがほとんどなくなる。これによりスクライブしたときのスクライブラインの直線性を向上させることができる。   Thus, the clearance can be set to an optimum value, for example, an interval of 2 μm. If the scribing is performed in this state, the position of the scribing wheel 30 in the holder groove 12 is stabilized, so that there is almost no left-right shaking with respect to the traveling direction of the scribing wheel 30. Thereby, the linearity of the scribe line when scribed can be improved.

尚この実施の形態ではピン孔１５，１６の両側より押さえカバー２１，２２を用いてピンを保持するようにしているが、一方のピン孔の径を支持部外周側で狭くしてピンを保持するようにしてもよい。   In this embodiment, the pins are held from both sides of the pin holes 15 and 16 by using the pressing covers 21 and 22, but the pin is held by reducing the diameter of one pin hole on the outer peripheral side of the support portion. You may make it do.

（第２の実施の形態）
次に本発明の第２の実施の形態について説明する。この実施の形態では図７に正面図、図８に断面図を示すように、ホルダの支持部１４側の上部に更に第２のねじ溝２６を形成すると共に、ホルダ溝をやや深くしたものであり、その他の構成は前述した第１の実施の形態と同様である。この実施の形態ではあらかじめねじ溝２６より締付防止ねじ２７を埋め込んでいき、支持部１３の内壁に接触させ、支持部間のホルダ溝１２の間隔が所定値以上に狭くなるように調整できないようにしている。こうすれば調整ねじ２３での調整時に締め付けすぎることを防止することができる。 (Second Embodiment)
Next, a second embodiment of the present invention will be described. In this embodiment, as shown in a front view in FIG. 7 and a cross-sectional view in FIG. 8, a second screw groove 26 is further formed in the upper part on the support portion 14 side of the holder, and the holder groove is slightly deepened. There are other configurations similar to those of the first embodiment. In this embodiment, the tightening prevention screw 27 is embedded in advance from the screw groove 26 and brought into contact with the inner wall of the support portion 13 so that the distance between the holder grooves 12 between the support portions cannot be adjusted to be narrower than a predetermined value. I have to. In this way, it is possible to prevent excessive tightening during adjustment with the adjusting screw 23.

尚この実施の形態ではねじ溝２６及び締付防止ねじ２７は夫々１つとしたが、複数であってもよい。   In this embodiment, one screw groove 26 and one fastening prevention screw 27 are provided, but a plurality of screw grooves 26 and fastening prevention screws 27 may be provided.

本実施の形態によるチップホルダユニットは、自動的に脆性材料基板をスクライブする自動スクライブ装置に限らず、脆性材料基板を手切りする脆性材料切断用カッターに取り付けて用いることもできる。   The chip holder unit according to the present embodiment is not limited to an automatic scribing device that automatically scribes a brittle material substrate, but can also be used by being attached to a brittle material cutting cutter that manually cuts a brittle material substrate.

本発明は、スクライブ中のスクライビングホイールの位置を安定させることができるので、スクライブを自動で行うスクライブ装置や、脆性材料基板を手切りする脆性材料切断用カッターに用いることができる。   Since the position of the scribing wheel during scribing can be stabilized, the present invention can be used for a scribing device that automatically performs scribing and a brittle material cutting cutter that manually cuts a brittle material substrate.
