Description
本発明は、板状の被加工物を切削加工する際に用いられるブレードを収容するためのブレードケースに関する。 The present invention relates to a blade case for housing a blade used when cutting a plate-like workpiece.
携帯電話機やパーソナルコンピュータに代表される電子機器では、電子回路等のデバイスを備えるデバイスチップが必須の構成要素になっている。デバイスチップは、例えば、シリコン等の半導体材料でなるウェーハの表面を複数の分割予定ライン(ストリート)で区画し、各領域にデバイスを形成した後、この分割予定ラインに沿ってウェーハを分割することで得られる。 In an electronic device typified by a mobile phone or a personal computer, a device chip including a device such as an electronic circuit is an essential component. The device chip is, for example, a method in which the surface of a wafer made of a semiconductor material such as silicon is partitioned by a plurality of planned division lines (streets), a device is formed in each region, and then the wafer is divided along the planned division lines. It is obtained by.
ウェーハを複数のデバイスチップへと分割する際には、例えば、回転軸(スピンドル)に環状のブレード(切削ブレード)が装着された切削装置を使用する。ブレードを高速に回転させた上で被加工物の分割予定ラインに沿って深く切り込ませることで、この被加工物を切断して複数のデバイスチップへと分割できる。 When dividing a wafer into a plurality of device chips, for example, a cutting apparatus in which an annular blade (cutting blade) is mounted on a rotating shaft (spindle) is used. The workpiece can be cut and divided into a plurality of device chips by rotating the blade at a high speed and then making a deep cut along the planned dividing line of the workpiece.
ブレードの一態様として、砥粒が結合材で固定された切刃のみでなるワッシャータイプが知られている。このワッシャータイプのブレードには、厚みが100μm以下の薄い物も多い。そこで、搬送等の際には、ブレードをブレードケースに収容してその破損を防いでいる(例えば、特許文献1参照)。 As an embodiment of the blade, a washer type is known which consists only of a cutting blade in which abrasive grains are fixed with a binder. Many of these washer-type blades have a thickness of 100 μm or less. Therefore, during conveyance or the like, the blade is accommodated in a blade case to prevent its breakage (see, for example, Patent Document 1).
ところで、上述のブレードケースは、例えば、ブレードを収容するための収容領域(凹部)のある収容部と、収容領域を閉じるための蓋部と、で構成されており、ブレードを収容領域に収容した状態で、蓋部によって収容領域が閉じられる。なお、このブレードケースでは、テープ等によって蓋部が収容部に留められることになる。 By the way, the above-mentioned blade case is composed of, for example, a storage part having a storage area (recessed part) for storing the blade and a lid part for closing the storage area, and the blade is stored in the storage area. In the state, the storage area is closed by the lid. In this blade case, the lid portion is fastened to the housing portion by tape or the like.
ブレードケースからブレードを取り出す際には、通常、収容部を下にした状態で蓋部側が開かれる。ブレードは、収容部の収容領域に収容されているので、仮に、蓋部側が開かれた状態でブレードケースを傾けたとしても、ブレードがブレードケースから脱落して破損することはない。 When taking out the blade from the blade case, the lid portion side is normally opened with the housing portion down. Since the blade is accommodated in the accommodating area of the accommodating portion, even if the blade case is tilted with the lid side open, the blade will not fall off the blade case and be damaged.
ところが、誤って、蓋部を下にした状態で収容部側を開いてしまうことがある。この場合には、収容部の収容領域によってブレードが保持されないので、例えば、ブレードケースを傾けてしまうと、ブレードがブレードケースから脱落して破損する恐れがある。 However, there is a case where the storage unit side is opened with the lid portion being lowered. In this case, since the blade is not held by the storage area of the storage unit, for example, if the blade case is tilted, the blade may fall off the blade case and be damaged.
本発明はかかる問題点に鑑みてなされたものであり、その目的とするところは、蓋部を下にした状態で収容部側を開いた場合でも、蓋部によりブレードを保持できるブレードケースを提供することである。 The present invention has been made in view of such problems, and an object of the present invention is to provide a blade case that can hold the blade by the lid even when the housing portion is opened with the lid facing down. It is to be.
本発明の一態様によれば、ワッシャータイプのブレードを収容するブレードケースであって、底板を有する収容部と、天板を有する蓋部と、該収容部と該蓋部とを開閉できるように連結するヒンジ部と、を備え、該底板には、該ブレードの外周よりも直径が大きく該ブレードを収容できる円形の凹部が設けられ、該天板には、該収容部に対して該蓋部が閉じられた状態において該凹部より外側で該底板に接する凸部が設けられているブレードケースが提供される。 According to one aspect of the present invention, there is provided a blade case for storing a washer-type blade, so that a storage portion having a bottom plate, a lid portion having a top plate, and the storage portion and the lid portion can be opened and closed. The bottom plate is provided with a circular recess having a diameter larger than the outer periphery of the blade and capable of accommodating the blade, and the top plate has the lid portion with respect to the accommodation portion. There is provided a blade case provided with a convex portion that is in contact with the bottom plate outside the concave portion in a closed state.
本発明の一態様において、該底板に設けられた該凹部の底、又は該天板の該凸部より内側の領域には、該収容部に対して該蓋部が開かれるとき、又は該蓋部に対して該収容部が開かれるときに、該ブレードと該底板、又は該ブレードと該天板との間に作用する静電気の力を抑制するための逃げ穴が設けられていることが好ましい。 In one embodiment of the present invention, when the lid is opened with respect to the housing portion, or on the bottom of the concave portion provided on the bottom plate, or on a region inside the convex portion of the top plate, or the lid It is preferable that a clearance hole is provided for suppressing the electrostatic force acting between the blade and the bottom plate or between the blade and the top plate when the accommodating portion is opened with respect to the portion. .
本発明の一態様に係るブレードケースは、収容部を構成する底板に、ブレードの外周よりも直径が大きくブレードを収容できる円形の凹部が設けられているとともに、蓋部を構成する天板に、収容部に対して蓋部が閉じられた状態において凹部より外側で底板に接する凸部が設けられている。そのため、蓋部を下にした状態で収容部側を開いた場合でも、凸部によってブレードが保持される。 The blade case according to one aspect of the present invention is provided with a circular recess having a diameter larger than the outer periphery of the blade and capable of accommodating the blade on the bottom plate constituting the accommodating portion, and on the top plate constituting the lid portion, A convex portion that contacts the bottom plate outside the concave portion in a state where the lid portion is closed with respect to the accommodating portion is provided. For this reason, even when the housing portion side is opened with the lid portion facing down, the blade is held by the convex portion.
添付図面を参照して、本発明の一態様に係る実施形態について説明する。図1は、本実施形態に係るブレードケース2の構成例を模式的に示す斜視図である。ブレードケース2は、切刃のみでなるいわゆるワッシャータイプのブレード(ワッシャーブレード)11を収容できるように構成されており、収容部4と蓋部6とを含む。 Embodiments according to one aspect of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view schematically showing a configuration example of a blade case 2 according to the present embodiment. The blade case 2 is configured to accommodate a so-called washer-type blade (washer blade) 11 including only cutting edges, and includes a storage portion 4 and a lid portion 6.
このブレードケース2に収容されるブレード11は、例えば、ダイヤモンド等の砥粒を金属や樹脂等の結合材で固めて、中央に開口部11aを有する環状に形成される。ブレード11の厚みは、代表的には、0.1mm〜0.3mm程度であり、ブレード11の外径(外周の直径)は、代表的には、54mm〜58mm程度である。ただし、ブレード11の材質、大きさ(径、厚み)、製法等に特段の制限はない。 The blade 11 accommodated in the blade case 2 is formed in an annular shape having an opening 11a in the center, for example, by solidifying abrasive grains such as diamond with a binder such as metal or resin. The thickness of the blade 11 is typically about 0.1 mm to 0.3 mm, and the outer diameter (outer diameter) of the blade 11 is typically about 54 mm to 58 mm. However, there are no particular restrictions on the material, size (diameter, thickness), manufacturing method, and the like of the blade 11.
収容部4及び蓋部6は、ヒンジ部8によって互いに連結されている。収容部4、蓋部6及びヒンジ部8の材質等に特段の制限はないが、本実施形態では、これらをポリプロピレン等の樹脂で一体に形成している。収容部4は、底板10を有しており、その一方の面10a側には、平面視で概ね円形の凹部12が設けられている。この凹部12が、ブレード11を収容する収容領域となる。よって、凹部12の直径は、ブレード11の外径よりも大きくなっている。 The accommodating portion 4 and the lid portion 6 are connected to each other by a hinge portion 8. Although there is no special restriction | limiting in the material etc. of the accommodating part 4, the cover part 6, and the hinge part 8, in this embodiment, these are integrally formed with resin, such as a polypropylene. The accommodating portion 4 has a bottom plate 10, and a substantially circular concave portion 12 is provided on the one surface 10 a side in a plan view. The recess 12 serves as a storage area for storing the blade 11. Therefore, the diameter of the recess 12 is larger than the outer diameter of the blade 11.
凹部12の中央には、凹部12の底面から突出する円柱状の凸部14が設けられている。凸部14の外周14aの直径は、ブレード11の内径(開口部11aの直径)よりも小さくなっている。また、凹部12の底面には、複数の穴(逃げ穴)16が凸部14を囲むように形成されている。 At the center of the recess 12, a columnar protrusion 14 that protrudes from the bottom surface of the recess 12 is provided. The diameter of the outer periphery 14a of the convex portion 14 is smaller than the inner diameter of the blade 11 (the diameter of the opening 11a). In addition, a plurality of holes (escape holes) 16 are formed on the bottom surface of the recess 12 so as to surround the protrusion 14.
このように、凹部12の底面に穴16を設けることで、底板10とブレード11との間に作用する静電気の力を弱められる。つまり、ブレードケース2に収容されたブレード11を取り扱い易くなる。また、ブレードケース2に収容されたブレード11を目視し易くなる。なお、本実施形態では、底板10を貫通しない平面視で概ね円形の穴16を設けているが、穴16の形状、配置、大きさ、数量等に特段の制限はない。また、底板10のヒンジ部8と反対側の位置には、外向きの爪部18が設けられている。 Thus, by providing the hole 16 on the bottom surface of the recess 12, the electrostatic force acting between the bottom plate 10 and the blade 11 can be weakened. That is, it becomes easy to handle the blade 11 accommodated in the blade case 2. Further, the blade 11 housed in the blade case 2 can be easily seen. In the present embodiment, the substantially circular hole 16 is provided in a plan view that does not penetrate the bottom plate 10. However, the shape, arrangement, size, quantity, and the like of the hole 16 are not particularly limited. An outward claw portion 18 is provided at a position opposite to the hinge portion 8 of the bottom plate 10.
蓋部6は、天板20を有している。天板20の一方の面20a側の外周部には、側壁22が設けられている。また、天板20の面20a側、且つ側壁22より内側の領域には、平面視で概ね環状の凸部24が設けられている。凸部24の内径は、凹部12の直径よりも大きくなっている。 The lid 6 has a top plate 20. A side wall 22 is provided on the outer peripheral portion on the one surface 20 a side of the top plate 20. Further, a substantially annular convex portion 24 is provided in a region on the surface 20 a side of the top plate 20 and on the inner side of the side wall 22 in a plan view. The inner diameter of the convex portion 24 is larger than the diameter of the concave portion 12.
面20aの凸部24で囲まれる領域の中央には、平面視で円形の凹部26が設けられている。凹部26の直径は、凸部14の外周14aの直径よりも僅かに大きくなっている。よって、この凹部26に凸部14を挿入できる。また、面20aの凸部24で囲まれた領域には、複数の穴(逃げ穴)28が凹部26を囲むように形成されている。 In the center of the region surrounded by the convex portion 24 of the surface 20a, a circular concave portion 26 is provided in plan view. The diameter of the concave portion 26 is slightly larger than the diameter of the outer periphery 14 a of the convex portion 14. Therefore, the convex portion 14 can be inserted into the concave portion 26. A plurality of holes (relief holes) 28 are formed so as to surround the recess 26 in the region surrounded by the protrusion 24 of the surface 20a.
このように、面20aの凸部24で囲まれた領域に穴28を設けることで、天板20とブレード11との間に作用する静電気の力を弱められる。つまり、ブレードケース2に収容されたブレード11を取り扱い易くなる。また、ブレードケース2に収容されたブレード11を目視し易くなる。 Thus, by providing the hole 28 in the region surrounded by the convex portion 24 of the surface 20a, the electrostatic force acting between the top plate 20 and the blade 11 can be weakened. That is, it becomes easy to handle the blade 11 accommodated in the blade case 2. Further, the blade 11 housed in the blade case 2 can be easily seen.
なお、本実施形態では、天板20を貫通しない平面視で概ね円形の穴28を設けているが、穴28の形状、配置、大きさ、数量等に特段の制限はない。また、ヒンジ部8の反対側に位置する側壁22の内側には、内向きの爪部30が設けられている。 In the present embodiment, the substantially circular hole 28 is provided in a plan view that does not penetrate the top plate 20, but the shape, arrangement, size, quantity, and the like of the hole 28 are not particularly limited. An inward claw portion 30 is provided on the inner side of the side wall 22 located on the opposite side of the hinge portion 8.
このように構成されたブレードケース2では、ヒンジ部8を支点に蓋部6を回転させて閉じることで、ブレード11を収容する凹部12を閉塞させられる。この状態で、爪部18と爪部30とを係合させれば、蓋部6の閉じた閉状態が維持される。一方で、蓋部6を開いた開状態では、凹部12も開放される。なお、収容部4に対して蓋部6が閉じられた閉状態では、上述した凸部24が凹部12より外側で底板10の面10aに接する。 In the blade case 2 configured as described above, the concave portion 12 that houses the blade 11 can be closed by rotating and closing the lid portion 6 with the hinge portion 8 as a fulcrum. If the claw part 18 and the claw part 30 are engaged in this state, the closed state where the lid part 6 is closed is maintained. On the other hand, in the open state where the lid 6 is opened, the recess 12 is also opened. In the closed state in which the lid portion 6 is closed with respect to the accommodating portion 4, the above-described convex portion 24 contacts the surface 10 a of the bottom plate 10 outside the concave portion 12.
次に、本実施形態に係るブレードケース2の使用例を説明する。図2(A)は、ブレード11が収容部4側に載せられた状態を模式的に示す断面図であり、図2(B)は、ブレード11がブレードケース2に収容された状態を模式的に示す断面図であり、図2(C)は、ブレード11が蓋部6側に載った状態を模式的に示す断面図である。 Next, a usage example of the blade case 2 according to the present embodiment will be described. 2A is a cross-sectional view schematically showing a state in which the blade 11 is placed on the accommodating portion 4 side, and FIG. 2B schematically shows a state in which the blade 11 is accommodated in the blade case 2. FIG. 2C is a cross-sectional view schematically showing a state in which the blade 11 is placed on the lid 6 side.
ブレードケース2にブレード11を収容する際には、例えば、図2(A)に示すように、収容部4の凹部12内にブレード11を配置する。すなわち、凹部12の底面にブレード11を載せる。なお、この凹部12内には、予め緩衝材等を配置しておくと良い。これにより、ブレード11の破損をより確実に防止できるようになる。 When the blade 11 is accommodated in the blade case 2, for example, the blade 11 is disposed in the concave portion 12 of the accommodating portion 4 as shown in FIG. That is, the blade 11 is placed on the bottom surface of the recess 12. It should be noted that a buffer material or the like is preferably placed in advance in the recess 12. Thereby, the breakage of the blade 11 can be prevented more reliably.
ブレード11を収容部4側に載せた後には、図2(B)に示すように、蓋部6を閉じて爪部18と爪部30とを係合させる。これにより、ブレード11は、ブレードケース2に収容される。なお、収容部4の凹部12内にブレード11を配置した状態で蓋部6を閉じると、蓋部6の凸部24で囲まれる領域とブレード11との間に空間が生まれる。 After the blade 11 is placed on the accommodating portion 4 side, as shown in FIG. 2B, the lid portion 6 is closed and the claw portion 18 and the claw portion 30 are engaged. Thereby, the blade 11 is accommodated in the blade case 2. Note that when the lid 6 is closed in a state where the blade 11 is disposed in the concave portion 12 of the housing portion 4, a space is created between the blade 11 and the region surrounded by the convex portion 24 of the lid portion 6.
この空間により、外部からの力がブレード11に伝わり難くなるので、ブレード11の破損を防止できる。更に、この空間を埋めるように、蓋部6の凸部24で囲まれる領域に予め緩衝材等を配置しておいても良い。これにより、ブレード11の破損をより確実に防止できるようになる。 This space makes it difficult for external force to be transmitted to the blade 11, thereby preventing the blade 11 from being damaged. Further, a buffer material or the like may be disposed in advance in a region surrounded by the convex portion 24 of the lid portion 6 so as to fill this space. Thereby, the breakage of the blade 11 can be prevented more reliably.
ブレード11をブレードケース2から取り出す際に、例えば、蓋部6を下にした状態で収容部4側を開いてしまった状況を想定する。この場合には、図2(C)に示すように、ブレード11が蓋部6側に載ることになる。本実施形態では、蓋部6に凸部24が設けられているので、仮に、ブレードケース2が傾いたとしても、ブレード11は凸部24によって保持される。よって、ブレード11がブレードケース2から脱落してしまうことはない。 When the blade 11 is taken out from the blade case 2, for example, a situation is assumed in which the accommodating portion 4 side is opened with the lid portion 6 facing down. In this case, the blade 11 is placed on the lid 6 side as shown in FIG. In the present embodiment, since the convex portion 24 is provided on the lid portion 6, even if the blade case 2 is inclined, the blade 11 is held by the convex portion 24. Therefore, the blade 11 does not fall off from the blade case 2.
なお、本実施形態では、ブレード11の載る面20aに穴28を設けているので、ブレードケース2の開閉等によって発生し、天板20とブレード11との間に作用する静電気の力(引力)は弱められる。よって、蓋部6からブレード11を容易に取り出せる。同様に、収容部4側にも穴16を設けているので、収容部4を下にした状態で蓋部6を開いた場合にも、底板10とブレード11との間に作用する静電気の力(引力)が弱められ、収容部4からブレード11を容易に取り出せる。 In the present embodiment, since the hole 28 is provided in the surface 20a on which the blade 11 is placed, electrostatic force (attraction) generated between the top plate 20 and the blade 11 is generated by opening and closing the blade case 2 or the like. Is weakened. Therefore, the blade 11 can be easily taken out from the lid 6. Similarly, since the hole 16 is provided also on the housing part 4 side, the electrostatic force acting between the bottom plate 10 and the blade 11 even when the lid part 6 is opened with the housing part 4 down. (Attraction) is weakened, and the blade 11 can be easily taken out from the accommodating portion 4.
以上のように、本実施形態に係るブレードケース2は、収容部4を構成する底板10に、ブレード11の外周よりも直径が大きくブレード11を収容できる円形の凹部12が設けられているとともに、蓋部6を構成する天板20に、収容部4に対して蓋部6が閉じられた状態において凹部12より外側で底板10に接する凸部24が設けられている。そのため、蓋部6を下にした状態で収容部4側を開いた場合でも、凸部24によってブレード11が保持される。 As described above, the blade case 2 according to the present embodiment is provided with the circular recess 12 having a diameter larger than the outer periphery of the blade 11 and accommodating the blade 11 on the bottom plate 10 constituting the accommodating portion 4. The top plate 20 constituting the lid portion 6 is provided with a convex portion 24 that is in contact with the bottom plate 10 outside the concave portion 12 when the lid portion 6 is closed with respect to the accommodating portion 4. Therefore, even when the accommodating portion 4 side is opened with the lid portion 6 down, the blade 11 is held by the convex portion 24.
なお、本発明は、上記実施形態等の記載に制限されず種々変更して実施可能である。例えば、上記実施形態では、蓋部6に環状の凸部24を設けているが、この凸部の形状、配置、数量等に特段の制限はない。例えば、複数の凸部を環状に配置することで、ブレード11を保持できるようにしても良い。 In addition, this invention is not restrict | limited to description of the said embodiment etc., A various change can be implemented. For example, in the said embodiment, although the cyclic | annular convex part 24 is provided in the cover part 6, there is no special restriction | limiting in the shape, arrangement | positioning, quantity, etc. of this convex part. For example, the blade 11 may be held by arranging a plurality of convex portions in an annular shape.
また、上記実施形態では、収容部4及び蓋部6の双方に複数の穴(逃げ穴)16,28を設けているが、例えば、収容部4及び蓋部6の一方にのみ1又は複数の穴を設けることもできる。もちろん、このような穴を設けなくても良い。 Moreover, in the said embodiment, although the some hole (relief hole) 16 and 28 is provided in both the accommodating part 4 and the cover part 6, for example, it is one or several in only one of the accommodating part 4 and the cover part 6. Holes can also be provided. Of course, such holes need not be provided.
その他、上記実施形態及び変形例に係る構造、方法等は、本発明の目的の範囲を逸脱しない限りにおいて適宜変更できる。 In addition, the structures, methods, and the like according to the above-described embodiments and modifications can be changed as appropriate without departing from the scope of the object of the present invention.
