【0001】
【発明の属する技術分野】
本発明は、電子部品の実装などに使用する基板の分割、特に短冊状になった基板を最終的な小基板に分割する、基板分割方法および基板分割装置に関する。
【0002】
【従来の技術】
プリント基板やセラミック基板などでは、矩形状の1枚の基板に、分割溝で分けられて、多数の小基板が縦・横連続して設けられ、個々の小基板上に回路パターンが構成され、その上にICやトランジスタ等の部品が搭載される。その後、矩形状の基板を、まずスクライブ溝を用いて小基板が一列に連なった短冊状の基板に分割し、さらに短冊状の基板から小基板へと最終的に分割する。この短冊状の基板から小基板へと分割する方法として、従来から以下のような方法が用いられてきた。
【0003】
図3に従来の基板分割装置の一例を示す。図3は基板分割装置を横方向から見た図である。図3において基板分割装置は、ベルトコンベア7、送りローラー8、加圧ローラー9で構成される。送りローラー8と加圧ローラー9は同じ直径で、その回転軸は基板の進行方向に直交して水平に配置され、加圧ローラー9の回転軸は送りローラー8の回転軸よりわずかに低く配置されている。また、10は短冊状の基板、11は基板10に搭載された搭載部品、12は基板10に設けられた分割溝を示している。基板10は、複数の小基板が互いに分割溝12を介して一列に連なっている。
【0004】
次に基板10の分割方法について説明する。基板10はベルトコンベア7で運ばれて送りローラー8の方に送られる。送りローラー8は送られてきた基板10を、ベルトコンベア7との間で押さえて上下に動かないように固定すると共に、加圧ローラー9の方に送り出す。加圧ローラー9の回転軸は送りローラー8の回転軸より低く配置されているため、加圧ローラー9によって基板10の先頭の小基板、あるいはそこに搭載された搭載部品11の上から下向きに圧力が加えられる。このとき、基板10の2番目の小基板はベルトコンベア7と送りローラー8で固定されている。この結果、基板10の先頭の小基板は、2番目の小基板との間の分割溝12で分割される。
【0005】
【発明が解決しようとする課題】
上記の基板分割方法では、送りローラー及び加圧ローラーが基板の部品搭載面に対して圧力を加えるため、部品搭載の条件によっては基板面に搭載された部品に対して上から圧力を加える可能性がある。そのため、この方法では搭載部品にダメージを与える可能性が強く、特にベアチップ搭載されているような部品の場合には致命的になる。
【0006】
また搭載部品は品種によってその形状が異なる。加圧ローラーの位置を固定化してあると、特に搭載部品の高さが異なる場合には、基板の種類によって加圧ローラーによる圧力が変化する。そして、圧力条件が安定しないため、基板が分割溝以外で割れたり分割部分にバリ等が発生したりする可能性がある。
【0007】
そこで本発明では、搭載部品に圧力を加えることなく、また搭載部品の形状によらずに一定の力で基板を分割できる基板分割方法と基板分割装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
上記問題を解決するために、本発明の基板分割方法は、複数の小基板を一列に配列してなる短冊状の基板を用意し、
回転軸が垂直で、互いに対向して逆方向に回転する一対の送りローラーを用いて、前記基板を側面からクランプして前方に送り出す工程と、
回転軸が垂直方向に対して前記基板の進行方向に傾斜し、互いに対向して逆方向に回転する一対の傾斜ローラーを用いて、前記基板の先端を側面からクランプして前方下方に送り出すことにより先頭の小基板を前記基板から分離・分割する工程を有することを特徴とする。
【0009】
また、本発明の基板分割装置は、複数の小基板を一列に配列してなる短冊状の基板を、小基板ごとに分割する基板分割装置であって、
回転軸が垂直で、互いに対向して逆方向に回転する一対の送りローラーと、
前記送りローラーに対して前記基板の進行方向に位置し、回転軸が垂直方向に対して前記基板の進行方向に傾斜し、互いに対向して逆方向に回転する一対の傾斜ローラーを有することを特徴とする。
【0010】
【発明の実施の形態】
本発明の基板分割装置の一実施例を図1に示す。図1(a)は基板分割装置の上面図、図1(b)は側面図である。図1において、基板分割装置は、分割ガイド1、送りローラー2、傾斜ローラー3で構成される。また、4は短冊状の基板、5は基板4上に搭載された搭載部品、6は基板4の分割溝を示している。基板4は、複数の小基板が互いに分割溝6を介して一列に連なっている。
【0011】
送りローラー2は、2本のローラー2a、2bで構成され、その回転軸は垂直に対向して配置され、互いに逆方向に同期して回転する。分割ガイド1は送りローラー2の2本のローラーの間に水平に配置される。一方、傾斜ローラー3は、2本のローラー3a、3bで構成され、その回転軸は垂直に対して基板4の進行方向に一定角度傾斜して対向して配置され、互いに逆方向に同期して回転する。
【0012】
次に基板4の分割方法について説明する。図2に、動作の流れを4つの部分に分けて斜視図で示す。
【0013】
図2において、基板4は、分割ガイド1にセットされた状態で送りローラー2の方に送り出される(図2(a))。送りローラー2は基板4をその長手方向側面からクランプし、上下や斜めに動かないように分割ガイド1とともに固定したまま、2a、2bが互いに逆方向に回転することで傾斜ローラー3の方に送り出す(図2(b))。
【0014】
傾斜ローラー3は送りローラー2から送り出された基板4の先端をその長手方向側面からクランプし、3a、3bが互いに逆方向に回転することでさらに先へ送り出そうとする。この時、傾斜ローラー3の回転軸は、送りローラー2の回転軸に対して基板4の進行方向に対して一定角度傾斜しているため、傾斜ローラー3でクランプされた基板4の先頭の小基板には進行方向下向きの力が加わる(図2(c))。この時、基板4の2番目の小基板は送りローラー2と分割ガイド1の間で固定されたままであるため、基板4の先頭の小基板は分割溝6に従って分割される(図2(d))。
【0015】
このとき、送りローラー2と傾斜ローラー3は共に、基板4に側面から圧力を加えるため、基板4上の搭載部品5には圧力は加わらない。
【0016】
【発明の効果】
本発明の基板分割方法によれば、短冊状の基板の側面をクランプした状態で、傾斜ローラーによる斜め方向の力で基板を分割するもので、基板表面に搭載された部品に圧力を与えることなく、また搭載部品の高さのバラツキ等によらず安定した条件で基板を分割することができ、基板の不必要な部分での割れや、分割部分のバリ等を最小限におさえることができる。また、本発明の基板分割装置によれば、比較的簡単な構成で基板分割ができ、また、基板上の搭載部品に圧力が加わることはないため部品に損傷を与えることがなく、信頼性の高い、高品質の基板分割が可能になる。

The feed roller 8 and the pressure roller 9 have the same diameter, and the rotation axis thereof is horizontally disposed perpendicular to the traveling direction of the substrate, and the rotation axis of the pressure roller 9 is slightly lower than the rotation axis of the feed roller 8. ing. Reference numeral 10 denotes a strip-shaped substrate, 11 denotes a mounting component mounted on the substrate 10, and 12 denotes a dividing groove provided on the substrate 10. In the substrate 10, a plurality of small substrates are connected in a row with the dividing grooves 12.

Next, a method for dividing the substrate 10 will be described. The substrate 10 is conveyed by the belt conveyor 7 and is sent toward the feed roller 8. The feeding roller 8 presses the substrate 10 that has been fed between the belt conveyor 7 and fixes it so as not to move up and down, and feeds it toward the pressure roller 9. Since the rotation axis of the pressure roller 9 is arranged lower than the rotation axis of the feed roller 8, the pressure roller 9 applies pressure downward from the top small substrate of the substrate 10 or the mounted component 11 mounted thereon. Is added. At this time, the second small substrate of the substrate 10 is fixed by the belt conveyor 7 and the feed roller 8. As a result, the first small substrate of the substrate 10 is divided by the dividing groove 12 between the second small substrate.

Therefore, this method has a strong possibility of damaging the mounted components, and is particularly fatal in the case of components that are mounted on a bare chip.
[0006]
In addition, the shape of mounted parts varies depending on the type. When the position of the pressure roller is fixed, particularly when the height of the mounted component is different, the pressure by the pressure roller changes depending on the type of the substrate. Since the pressure condition is not stable, there is a possibility that the substrate is cracked at other than the dividing groove or a burr is generated at the divided portion.
[0007]
Therefore, an object of the present invention is to provide a substrate dividing method and a substrate dividing apparatus that can divide a substrate with a constant force without applying pressure to the mounted component and without depending on the shape of the mounted component.

DETAILED DESCRIPTION OF THE INVENTION
One embodiment of the substrate dividing apparatus of the present invention is shown in FIG. FIG. 1A is a top view of the substrate dividing apparatus, and FIG. 1B is a side view. In FIG. 1, the substrate dividing apparatus includes a dividing guide 1, a feed roller 2, and an inclined roller 3. Reference numeral 4 denotes a strip-shaped substrate, 5 denotes a mounting component mounted on the substrate 4, and 6 denotes a dividing groove of the substrate 4. In the substrate 4, a plurality of small substrates are connected in a row with the dividing grooves 6.
[0011]
The feed roller 2 is composed of two rollers 2a and 2b, and their rotation axes are arranged vertically opposite to each other and rotate in synchronization with each other in opposite directions. The division guide 1 is horizontally disposed between the two rollers of the feed roller 2. On the other hand, the inclined roller 3 is composed of two rollers 3a and 3b, and their rotation axes are arranged to be opposed to each other at a predetermined angle with respect to the vertical direction in the traveling direction of the substrate 4, and are synchronized with each other in opposite directions.

In FIG. 2, the board | substrate 4 is sent out toward the feed roller 2 in the state set to the division | segmentation guide 1 (FIG. 2 (a)). The feed roller 2 clamps the substrate 4 from the side surface in the longitudinal direction and feeds it toward the tilt roller 3 by rotating 2a and 2b in opposite directions while being fixed together with the division guide 1 so as not to move up and down or obliquely. (FIG. 2 (b)).
[0014]
The tilting roller 3 clamps the front end of the substrate 4 fed from the feed roller 2 from the side surface in the longitudinal direction, and tries to feed further by rotating 3a and 3b in opposite directions. At this time, the rotation axis of the inclined roller 3 is inclined at a certain angle with respect to the rotation direction of the substrate 4 with respect to the rotation axis of the feed roller 2, so that the top small substrate of the substrate 4 clamped by the inclined roller 3 is used. A downward force in the traveling direction is applied to (Fig. 2 (c)). At this time, since the second small substrate of the substrate 4 remains fixed between the feed roller 2 and the dividing guide 1, the leading small substrate of the substrate 4 is divided according to the dividing groove 6 (FIG. 2D). ).
[0015]
At this time, since both the feed roller 2 and the inclined roller 3 apply pressure to the substrate 4 from the side, no pressure is applied to the mounting component 5 on the substrate 4.
[0016]
【The invention's effect】
According to the substrate dividing method of the present invention, the substrate is divided by the force in the oblique direction by the inclined roller in a state where the side surface of the strip-shaped substrate is clamped, and without applying pressure to the components mounted on the substrate surface. In addition, the substrate can be divided under stable conditions regardless of variations in the height of mounted components, and cracks at unnecessary portions of the substrate and burrs at the divided portions can be minimized. Further, according to the substrate dividing apparatus of the present invention, the substrate can be divided with a relatively simple configuration, and since no pressure is applied to the mounted components on the substrate, the components are not damaged, and the reliability is improved. High-quality and high-quality substrate division is possible.
