Description

本発明は、セラミックス基板等の板状物を複数個に分割し、面取り加工するのに適した切削装置に関する。   The present invention relates to a cutting apparatus suitable for dividing a plate-like object such as a ceramic substrate into a plurality of parts and chamfering them.

IC、LSI、コンデンサ等のデバイスはセラミックス基板等の配線基板に実装され、各種の電気機器に利用される。内部にコンデンサやインダクタ等を集積した低温同時焼成セラミックス(LTCC)等の板状物は、切削装置によって分割予定ラインに沿って切断されて、複数個の小片基板に分割される。   Devices such as ICs, LSIs, capacitors, etc. are mounted on a wiring board such as a ceramic substrate, and are used in various electric devices. A plate-like object such as a low-temperature co-fired ceramic (LTCC) in which capacitors, inductors and the like are integrated is cut along a division line by a cutting device and divided into a plurality of small-piece substrates.

LTCCは900〜1000℃以下の低温で焼成することで、焼成後の収縮を押さえ受動部品のパターンを崩すことなくコンデンサやインダクタを内部回路として集積したものであり、無線回路において信号を前処理するモジュールに利用される。   LTCC is obtained by firing at a low temperature of 900 to 1000 ° C. or lowering the shrinkage after firing, and integrating capacitors and inductors as an internal circuit without destroying the pattern of passive components, and preprocesses signals in a radio circuit. Used for modules.

このような板状物から分割された小片基板は、その角は鋭く危険性が高いことから個々の小片基板の角を面取り加工する必要がある。従来は、分割装置により板状物を小片基板に分割し、その後面取り加工装置により角部を面取り加工するようにしていた。   Since the small substrate divided from such a plate-shaped substrate has a sharp corner and high risk, it is necessary to chamfer the corner of each small substrate. Conventionally, a plate-like object is divided into small pieces by a dividing device, and then a corner portion is chamfered by a chamfering processing device.

しかし、従来の加工方法では、板状物を小片基板に分割する分割装置と小片基板に面取り加工を施す面取り加工装置が必要であり、不経済であるという問題がある。   However, the conventional processing method requires a dividing device that divides a plate-like object into small piece substrates and a chamfering device that chamfers the small piece substrates, which is uneconomical.

また、一台の分割装置で板状物を小片基板に分割し、その後小片基板に角部の面取り加工を施そうとすると、分割工程の後にチャックテーブルを取り替える等の段取り替えをしなければならず、生産性が悪いという問題がある。   In addition, if a plate-like object is divided into small substrates with a single dividing device, and then the corner substrate is chamfered, it is necessary to change the setup such as changing the chuck table after the dividing step. There is a problem that productivity is poor.

本発明はこのような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、チャックテーブルを交換せずに板状物に対する分割加工及び角部面取り加工を施すことが可能な切削装置を提供することである。   The present invention has been made in view of the above points, and an object of the present invention is to provide a cutting apparatus capable of performing division processing and corner chamfering processing on a plate-like object without replacing the chuck table. Is to provide.

本発明によると、板状物を保持し回転可能なチャックテーブルと、該チャックテーブルに保持された板状物を小片に分割する切削ブレードが装着された切削手段を備えた切削装置であって、該チャックテーブルは、板状物の切削によって分割された複数の小片板状物を吸引保持する複数の小片吸着テーブルと、該各小片吸着テーブルに連結され、該各小片吸着テーブルを互いに接触する位置に集合させるとともに互いに離反させる集合離反手段と、を具備したことを特徴とする切削装置が提供される。   According to the present invention, there is provided a cutting apparatus comprising a chuck table that holds and rotates a plate-like object, and a cutting means that is equipped with a cutting blade that divides the plate-like object held on the chuck table into small pieces, The chuck table is connected to the plurality of small piece suction tables for sucking and holding the plurality of small piece plate-like objects divided by cutting the plate-like object, and the position where the small piece suction tables are in contact with each other. There is provided a cutting device characterized in that it comprises gathering and separating means for gathering together and separating them from each other.

本発明の切削装置は、分割された小片基板に対応した複数の小片吸着テーブルを備えるとともに、小片吸着テーブルを集合及び離反させる集合離反手段を有しているため、切削ブレードで板状物を小片基板に分割した後に小片基板を互いに離反させて、小片基板の角部を切削ブレードで切削して面取り加工を施すことができるので、経済的である。   The cutting apparatus according to the present invention includes a plurality of small piece suction tables corresponding to the divided small piece substrates and has a set separation means for collecting and separating the small piece suction tables. Since the small substrates are separated from each other after being divided into substrates and the corner portions of the small substrates are cut with a cutting blade, it is economical.

図2を参照すると、本発明実施形態のチャックテーブルユニット14の分解斜視図が示されている。チャックテーブルユニット14は支持基台18と、支持基台18上に搭載されるチャックテーブル20とを含んでいる。支持基台18には対角線方向に伸長する4個の長穴56が形成されており、各長穴56中には吸引パイプ58がスライド自在に挿入されている。   Referring to FIG. 2, an exploded perspective view of the chuck table unit 14 according to the embodiment of the present invention is shown. The chuck table unit 14 includes a support base 18 and a chuck table 20 mounted on the support base 18. Four long holes 56 extending diagonally are formed in the support base 18, and suction pipes 58 are slidably inserted into the long holes 56.

吸引パイプ58のスライド機構としては、特に図示しないが例えばエアシリンダ等を採用可能である。各吸引パイプ58はフレキシブルホースを介して真空ポンプ等の真空吸引源に接続されている。   As a slide mechanism of the suction pipe 58, for example, an air cylinder or the like can be adopted although not shown.

次に、図4及び図5を参照して、以上のように構成されたチャックテーブルユニット14を有する切削装置2により板状物を複数に分割し、分割された小片基板の角部を面取り加工する方法について説明する。   Next, referring to FIG. 4 and FIG. 5, the plate-like object is divided into a plurality of parts by the cutting apparatus 2 having the chuck table unit 14 configured as described above, and the corners of the divided small-sized substrates are chamfered. How to do will be described.

まず、図4(A)に示すように、LTCC等の板状物62をチャックテーブル20上に搭載し、チャックテーブル20により吸引保持する。そして、板状物62を切削ブレード32により切削して、図4(B)に示すように、板状物62に互いに直交する切削ライン63を形成して、板状物62を4個の小片基板64に分割する。   First, as shown in FIG. 4A, a plate-like object 62 such as LTCC is mounted on the chuck table 20 and sucked and held by the chuck table 20.

Divide into substrates 64.

次いで、上述した集合離反手段を駆動して分割された小片基板64を図4(C)に示すように互いに離反させる。次いで、チャックテーブルユニット14を適宜回転させながら各小片基板64の角部64aに図5(A)に示すように面取り加工を施す。   Next, the small substrate 64 divided by driving the collective separation means described above is separated from each other as shown in FIG. Next, as shown in FIG. 5A, chamfering is performed on the corner portion 64a of each small substrate 64 while the chuck table unit 14 is appropriately rotated.

小片基板64は互いに十分に離間されているため、各小片基板64の全ての角部64aに切削ブレード32により面取り加工を施すことができる。これにより、図5(B)に示すように、全ての角部に面取り部65を有する小片基板64を得ることができる。   Since the small piece substrates 64 are sufficiently separated from each other, all the corner portions 64a of the small piece substrates 64 can be chamfered by the cutting blade 32. As a result, as shown in FIG. 5 (B), a small substrate 64 having chamfered portions 65 at all corners can be obtained.
