Description

【0001】
【発明の属する技術分野】
本発明は、一端または両端に高精度な打抜き対象部を有する製品を複数個形成したフレキシブルプリント配線板からその製品を切断する切断方法に関するものである。
【0002】
【従来技術】
フレキシブルプリント配線板には、一端または両端にコネクタに嵌合される被嵌合部を有する製品が複数個形成され、打抜きで1製品ずつ分離される。
従来、製品個々の打抜きは、特許第2662477号公報に開示するようにマルチパンチで高精度を要するその被嵌合部を打抜いた後、被嵌合部分を除く製品の外周を、トムソン型を利用して打抜いている。
【0003】
このように、パンチを使用すると、先端に打抜きカスが付着するパンチで被嵌合部分の打ち抜きが継続されて、歩留まりを悪くする。
しかも、パンチの場合、被嵌合部分に相応する大きさのパンチとダイとを備えた多種の金型を製作用意し、在庫管理してその都度交換作業する必要もあった。その上、トムソン抜きは、専用の加工機までフレキシブルプリント配線板を搬送して行われるため、専用の加工機使用による設備費高騰で生産コストがアップする問題もある。
【0004】
【発明が解決しようとする課題】
本発明は上記従来事情に鑑みてなされたもので、その目的とする処は、打抜きカスによる歩留まりの低下を防止するフレキシブルプリント配線板の切断方法を提供することにある。
他の目的とする処は、端部に相応する大きさのパンチとダイとを備えた多種の金型を敢えて製作用意せずとも、様々な大きさの製品端部に適応してその製品端部を精度良く打抜き加工するフレキシブルプリント配線板の切断方法を提供することにある。
そして、更に他の目的とする処は、トムソン抜きを使用せずに製品の外周全体を打抜き加工するフレキシブルプリント配線板の切断方法を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を解決するために講じた技術的手段は、一対の平行刃と、少なくとも一対の平行刃間の長さを有する中間刃とを備え、一対の平行刃でフレキシブルプリント配線板に形成された製品端部の平行する両端縁を打抜き、中間刃で前記両端縁間の縁を打抜くことを特徴とするフレキシブルプリント配線板の切断方法である(請求項1)。
即ち、一対の平行刃と、中間刃とを併用して打抜きカスを発生させずに製品端部を打抜き加工する。
打抜き加工に際しては、フレキシブルプリント配線板に付されたターゲットマークを撮像してその中心を画像処理しで中心を検出したり、パターンマッチング法を使用して行う。
【0006】
そして、一対の平行刃が間隔を調整可能に形成されていると、様々な大きさの製品端部に適応させる上で最適なものである(請求項2)。この請求項2にあっては、少なくとも最大限に調整された一対の平行刃間隔の長さを有する中間刃を使用する(請求項2)。また、長さを異にする数種の中間刃の中から交換可能に選択使用するようにしても良いものである。
【0007】
その上、中間刃を有効利用してフレキシブルプリント配線板に形成された製品端部以外の外周部分を打抜くようにすると、トムソン抜きを不用にすることができる(請求項3)。
【0008】
前記平行刃における同一側の端部各々を、外向きに折曲形成された刃部で構成していると、図10に示すように製品A端部以外の外周側にその刃部S1aを向けた状態で製品Aの平行する両端縁a1、a1を平行刃S1、S1で打抜くことによって、中間刃S2を利用して製品A端部以外の外周部分を打抜く時に、その刃部S1aで打ち抜かれた箇所に交差する中間刃S2の打抜き角度の自由度を拡大させ、それによって全長に亘って直線状を呈する変化の少ない製品Aであっても、その端部以外の外周の打抜きを中間刃S2で連続して行えるようにする(請求項4)。
【0009】
そして、前記刃部とは逆側の平行刃端部各々を、その刃部とは逆向きに折曲形成された逆向き傾斜刃部で構成していると、同図10に示すように平行刃S1による製品A端部の平行な両端縁a1、a1の打抜き後に、前記逆向き傾斜刃部S1bによる打抜き部中途を交差するように中間刃S2で打抜くことによって、製品Aにおける両端縁a1、a1先端両縁部分に幅寸法を縮小する方向に傾斜する平面視ハの字状の傾斜案内部a3、a3を形成し、これがコネクタへの接続時のガイドとなる(請求項5)。
【0010】
【発明の実施の形態】
次に、本発明フレキシブルプリント配線板の切断方法の実施の形態を図面に基づいて説明すると、図1は切断方法の工程を示している。
【0011】
図1に示す製品Aを複数形成したフレキシブルプリント配線板における製品端部である被嵌合部aには、コネクタに嵌合させるために高精度な打抜きが要求され、一対の平行刃S1、S1で図1(b)に示すように被嵌合部aの平行する両端縁a1、a1を同時に打抜き、そして少なくともその平行刃S1、S1間の長さを有する中間刃S2で図1(c)に示すように被嵌合部aにおける両端縁a1、a1間の縁a2を打ち抜き、しかる後、図1(d)に示すように被嵌合部aを除く製品Aの外周を、同中間刃S2を数度下降させて打抜いている。
【0012】
この切断方法の実施の形態では、フレキシブルプリント配線板FPにおける各製品近傍やフレキシブルプリント配線板FPの所望箇所にマークを付し、このフレキシブルプリント配線板FPをワークホルダWHに着脱可能に取着し、そのワークホルダWHの一縁を移動機構KでクランプしてX・Y軸線方向に制御動させて、前記マークを加工機Mに設けられている撮像手段(カメラ)Cで撮像してその中心を検出し、しかる後、マークの中心座標に対して固定的な距離をもって離間している製品端部aを、加工機Mに設けられている一対の平行刃S1、S1と、中間刃S2とを使用して打抜き、製品端部aを除く製品Aの外周を中間刃S2で打抜くようになっている(図2、図3参考)。
この一対の平行刃S1、S1、中間刃S2を有するカッターホルダKH各々は、図4、図5に示すように一対の平行刃S1、S1間の中間部分、中間刃S2の中間部分に相当する上面部分各々から連絡用差込軸1を突設し、加工機Mに駆動源で上下動可能とする動力受軸Dにその連絡差込軸1を周方向に回動可能に差し込み且つ止めネジ100でその任意な回動角度状態を固定できるようになっており、その周方向への回動角度調整可能な構成によって製品端部aを打抜く際の一対の平行刃S1、S1の向き設定、製品端部aを打抜く際の中間刃S2の向き設定、製品端部aを除く製品Aの外周を打抜く際の中間刃S2の向き設定が各々行えるようになっている。
尚、符号101は止めネジ100の差込孔である。
【0013】
加工機Mの詳細を図2、図3をもとに説明すると、この図2、図3は前記平行刃S1、S1、中間刃S2の昇降機構2、回動機構3の具体例を示している。
符号Uは、ベースEに設置される略コ字状のユニットであり、このユニットUに前記動力受軸Dを垂直状態で支持して、その動力受軸D下端に前記する連絡用差込軸1を軸方向に回動可能に差込み、止めネジ100で着脱可能に取付られている。
前記動力受軸Dは、その中間部から下端部にかけての部分にスプラインd1を形成すると共に、軸外周部上端に送りネジ部d2を螺刻してなり、該スプラインd1を有する軸部と送りネジ部d2を有する軸部とは、軸方向に互いに回動可能に係合されており、前記動力受軸Dには、そのスプラインd1外周にスプライン筒4を摺動可能に嵌合しており、この動力受軸Dは前記スプライン筒4を介してタイミングプーリー5の内部に嵌装されている。
【0014】
また、動力受軸D上部の送りネジ部d2にはナット部材6が螺嵌されると共に、このナット部材6を前記ユニットU一端の上面に固定される上部ケース7の支持孔17内に対してベアリングBLを介して内嵌し、このナット部材6の下部には、タイミングプーリー8が固定されている。
【0015】
回動機構3は、ユニットU内の収容空間に電気的に制御可能なモータ(ステッピングモータやサーボモータ等)M1を設置し、その出力軸M1’に設けたモータープーリー13と、前記タイミングプーリー5とに亘ってタイミングベルトTBを架け渡して構成されている。
【0016】
また、昇降機構2は、上部ケース7に取付固定される電気的に制御可能なモータM2(ステッピングモータやサーボモータ等)の出力軸M2’にモータープーリー12を取付け、該モータープーリー12と前記タイミングプーリー8との間にタイミングベルトTBを架け渡して構成されている。
平行刃S1、S1を有するカッターホルダKH、中間刃S2を有するカッターホルダKHは、図示するようにこの実施の形態では並設するユニットU各々に個別に設けられている。
【0017】
以上のように、モータM1’の回転量によって前記するように動力受軸Dと同軸な連絡差込軸1を周方向に回動させて、平行刃S1、S1、中間刃S2をその任意な回動状態で固定することができ、またモータM2を正転、逆転させてタイミングプーリー8とナット部材6とを回動させると、スプライン筒4にて回動が規制された状態で支持される動力受軸Dがナット部材6と送りネジ部d2との螺合によってカッターホルダKHを上下に制御させることができる。
従って、前記移動機構Kを制御動してフレキシブルプリント配線板FPの各製品Aの端部を平行刃S1、S1、中間刃S2の直下に制御動させる度にモータM1’、M1’を制御してその平行刃S1、S1、中間刃S2を所望する回動角度に調整しつつ、モータM2’、M2’を制御することによって、前記図1(b)(c)(d)に示す工程をもって製品Aを打抜くことができる。
【0018】
次に、図6〜図9について説明すると、この実施の形態は、間隔を調整可能とする一対の平行刃S1、S1と、長さを異にする数種の中から選択された中間刃S2とを交換可能に選択使用して製品Aの端部と共に製品Aの外周を打抜き加工するものである。
【0019】
図6、図7は、一対の平行刃S1、S1のカッターホルダKHへの支持構造(下記では平行刃支持構造と称する)9を、図8、図9は、中間刃S2のカッターホルダへの支持構造(下記では中間刃支持構造と称する)10を各々示している。
【0020】
平行刃支持構造9は、図7に示すように下面を開放する箱状に形成されたカッターホルダKHのその両短手側面中央部に亘って周方向に回動可能で且つ軸方向移動可能に支持された回動軸19と、その回動軸19の中央部を境に各々一半部に螺設した逆螺子部29、29と、その回動軸19の中途部分に同軸上をもって固定された第1傘歯車39と、長手側面の一面に回転操作可能に貫通状に設けられ内端に前記第1傘歯車39に噛合する第2傘歯車59を備えた操作軸49とを備えた構成になっている。
【0021】
前記平行刃支持構造9のカッターホルダKHは、その内部スペースの短手側奥行きを平行刃S1の長さよりもほんの僅か広くしてある。
前記操作軸49にはその外端に、ドライバー等の工具の差し入れ凹部49aが凹設してあり、この操作軸49を正転、逆転することによって、平行刃S1、S1間隔が調整できるようになっている。
【0022】
また、カッターホルダKHの一長手側面には、平行刃S1、S1の一側端面に螺合する固定ネジ69の軸部を挿通するガイド長孔79、79を開孔し、その固定ネジ69の緊締によって間隔調整された平行刃S1、S1を固定できるようになっている。
【0023】
中間刃支持構造10は、図9に示すように中間刃S2の基部を抜き差し可能とする抜き差し溝10aを開溝したカッターホルダKHの前面に止めネジ100の差込孔101を開孔した構成であり、止めネジ100を弛緩ことによって、長さを異にする中間刃S2と交換可能に保持できるようになっている。
【0024】
尚、符号1は、前記実施の形態と同様の連絡用差込軸、Dはその連絡用差込軸1が抜き差し可能に同軸上に接続される動力受軸、100は連絡用差込軸1をその周方向に所望に回動させた状態で固定する止めネジである。
【0025】
以上のように、操作軸49を回転操作して平行刃S1、S1の間隔を製品Aの端部の平行する両端縁a1、a1間隔に一致させ、前記移動機構Kを制御動してフレキシブルプリント配線板FPの各製品端部を平行刃S1、S1、中間刃S2の直下に制御動させる度にモータM1’、M1’を制御して平行刃S1、S1、中間刃S2を所望な回動角度に調整しつつ、モータM2’、M2’を制御することによって、様々な大きさの製品Aの端部に適応して、前記図1(b)(c)(d)に示す工程をもって製品Aを打抜くことができる。
尚、請求項2の実施の形態については詳述しないが、中間刃S2の長さが不変である点を除いて差異はなく、カッターホルダKHへの支持構成については、図5や図8に示す構造を採用する。
【0026】
次に図10に基づいて説明すると、この実施の形態は、フレキシブルプリント配線板の切断方法の他の実施の形態を示している。
この実施の形態は、平行刃S1、S1における同一側の端部各々を、外向きに折曲形成された刃部S1a、S1aで構成すると共に、前記刃部S1a、S1aとは逆側の平行刃S1、S1端部各々を、その刃部S1a、S1aとは逆向きに折曲形成された逆向き傾斜刃部S1b、S1bで構成している。
この実施の形態では、図10(a)や(b)に示すように、一対の平行刃S1、S1で被嵌合部aの平行する両端縁a1、a1を同時に打抜き、そして逆向き傾斜刃部S1b、S1bで打抜かれた箇所に交差するように中間刃S2で被嵌合部aにおける両端縁a1、a1間の縁a2を打ち抜き、しかる後、被嵌合部aを除く製品Aの外周を、前記刃部S1a、S1aで打抜かれた箇所に交差するように打ち込まれる中間刃S2の下降を始まりとしてその中間刃S2を必要数下降させて全長に亘って直線状を呈する変化の少ない製品Aを打抜いている。
短寸な製品Aは、図10(a)に示すように、製品Aの外周を打抜く時に、刃部S1aで打抜かれた箇所に必ず交差するようにして中間刃S2で打抜くことができる。
また、長尺な製品Aは、図10(b)に示すように、刃部S1aで打抜かれた箇所への交差範囲の拡大で中間刃S2の打抜き角度の自由度を大きくして、中間刃S2で打抜かれる箇所を確実に連続させることができるようになっている。
そして、図10(a)(b)共に平行刃S1、S1による製品A端部の平行な両端縁a1、a1の打抜き後に、刃部S1a、S1aによる打抜き部中途を交差するように中間刃S2で製品端部の平行する両端縁間の縁a2を打抜くことによって、打抜かれた製品には、その端部先端両縁部分に幅寸法を縮小する平面視ハの字状の傾斜案内部a3が形成され、これがコネクタへのガイド部を構成している。
【0027】
【発明の効果】
本発明は以上のように一対の平行刃と、その平行刃間の長さを有する中間刃とを備えており、平行刃と、中間刃とを使用して製品端部を打抜き加工するようにしており、打抜きカスが打抜き手段に付着したままでの打抜き加工を継続すれ虞れがなく歩留まりの低下を防止することができる。
しかも、その一対の平行刃が間隔を調整可能とし、中間刃の長さを少なくとも最大限に調整された一対の平行刃間の長さにしていると、平行刃と、その中間刃とで様々な大きさの製品端部を打抜き加工することができる。
従って、製品端部に相応する大きさのパンチとダイとを備えた多種の金型を敢えて製作用意する必要がなく、設備コストが高コストにならず、製品端部の大きさ毎に金型を交換する作業が一切不用である。
その上、中間刃で製品端部以外の外周部分を打抜くようにしている請求項3にあっては、製品端部を打抜き加工する手段を有効利用してトムソン抜きしていた部分が打抜ける。
また、平行刃における同一側の端部各々を、外向きに折曲形成された刃部で構成していると、全長に亘って直線状を呈する変化の少ない製品を打抜くに際して、実施の形態で示すようにその刃部で打抜かれた箇所に必ず交差するようにして中間刃を打抜くことができたり(短寸な製品)、その刃部で打抜かれた箇所への交差範囲の拡大で中間刃の打抜き角度の自由度を大きくして、中間刃で打抜かれる箇所を確実に連続させることができ(長尺な製品)、便利である。
そして、前記刃部とは逆側の平行刃端部各々を、その刃部とは逆向きに折曲形成された逆向き傾斜刃部で構成している場合には、平行刃による製品端部の平行な両端縁の打抜き後に、逆向き傾斜刃部による打抜き部中途を交差するように中間刃で打抜くことによって、打抜かれた製品における端部先端両縁部分に平面視ハの字状の傾斜案内部を形成するから、その傾斜案内部がコネクタへの接続時のガイドになり、コネクタへの嵌合を簡単に行う上で好都合である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cutting method for cutting a product from a flexible printed wiring board on which a plurality of products having high-precision punching target portions at one or both ends are formed.
[0002]
[Prior art]
On the flexible printed wiring board, a plurality of products having fitting portions fitted to the connector at one or both ends are formed, and the products are separated one by one by punching.
Conventionally, as for the punching of individual products, as disclosed in Japanese Patent No. 2662477, after punching out the fitting portion requiring high precision with a multi-punch, the outer periphery of the product excluding the fitting portion is formed by a Thomson type. I'm using and punching.
[0003]
As described above, when the punch is used, the punching of the fitted portion is continued with the punch to which the punch residue adheres to the tip, and the yield is deteriorated.
In addition, in the case of punches, it is necessary to prepare and prepare various types of dies having punches and dies of a size corresponding to the parts to be fitted, manage the stock, and perform a replacement operation each time. In addition, since Thomson punching is performed by transporting a flexible printed wiring board to a dedicated processing machine, there is also a problem that production costs increase due to a rise in equipment costs due to the use of the dedicated processing machine.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a method for cutting a flexible printed wiring board, which prevents a reduction in yield due to punched waste.
Another purpose is to adapt to various sizes of product ends without intentionally producing and preparing various types of dies having punches and dies of the size corresponding to the ends. It is an object of the present invention to provide a method for cutting a flexible printed wiring board in which a portion is punched with high precision.
Another object of the present invention is to provide a method for cutting a flexible printed wiring board, which punches the entire outer periphery of a product without using Thomson punching.
[0005]
[Means for Solving the Problems]
The technical measures taken to solve the above object include a pair of parallel blades, an intermediate blade having a length between at least the pair of parallel blades, and formed on the flexible printed wiring board with the pair of parallel blades. A method for cutting a flexible printed wiring board, comprising punching both parallel edges of a product end and punching an edge between the both edges with an intermediate blade (claim 1).
That is, a pair of parallel blades and an intermediate blade are used in combination, and the end of the product is punched without generating punching waste.
At the time of punching, the target mark attached to the flexible printed wiring board is imaged, and its center is subjected to image processing to detect the center, or is performed using a pattern matching method.
[0006]
When the pair of parallel blades is formed so that the interval can be adjusted, it is optimal for adapting to various sizes of product end portions (claim 2). According to the second aspect, an intermediate blade having a length of a pair of parallel blades adjusted at least to the maximum is used (claim 2). In addition, it is also possible to select and use a plurality of intermediate blades having different lengths in a replaceable manner.
[0007]
In addition, if the outer peripheral portion other than the product end portion formed on the flexible printed wiring board is punched by effectively utilizing the intermediate blade, the Thomson punching can be made unnecessary (claim 3).
[0008]
When each end on the same side of the parallel blade is constituted by a blade bent outward, the blade S1a is directed to the outer peripheral side other than the end of the product A as shown in FIG. By punching the parallel both edges a1 and a1 of the product A with the parallel blades S1 and S1 in the state in which the product A is cut, when the outer peripheral portion other than the end of the product A is punched using the intermediate blade S2, the blade portion S1a is used. The degree of freedom of the punching angle of the intermediate blade S2 intersecting the punched portion is increased, so that even the product A that exhibits a straight line over the entire length and has little change can be used for punching the outer periphery other than the end. This can be performed continuously by the blade S2 (claim 4).
[0009]
When each of the parallel blade ends opposite to the blade portion is constituted by a reversely inclined blade portion formed to be bent in a direction opposite to the blade portion, the parallel blade ends are parallel as shown in FIG. After punching both ends a1 and a1 of the parallel end of the product A by the blade S1, by punching with the intermediate blade S2 so as to cross the middle of the punched portion by the reverse inclined blade S1b, both ends a1 in the product A are obtained. , A1 are formed at both ends of the leading end with inclined guide portions a3, a3, which are inclined in the direction of reducing the width dimension and have a C-shape in plan view, and serve as guides when connecting to the connector (claim 5).
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a method for cutting a flexible printed wiring board according to the present invention will be described with reference to the drawings. FIG. 1 shows steps of the cutting method.
[0011]
In the flexible printed wiring board in which a plurality of products A shown in FIG. 1 are formed, the fitting end a, which is the product end, is required to be punched with high precision in order to fit the connector, and a pair of parallel blades S1, S1 As shown in FIG. 1 (b), both end edges a1, a1 of the fitted portion a are parallel punched out at the same time, and at least an intermediate blade S2 having a length between the parallel blades S1, S1 is used as shown in FIG. 1 (c).

The parallel blade and the intermediate blade are used to punch a product end. Therefore, there is no fear that the punching process is continued while the punching waste remains attached to the punching means, and a decrease in yield can be prevented.
In addition, if the pair of parallel blades is capable of adjusting the interval and the length of the intermediate blade is at least the length between the pair of parallel blades adjusted to the maximum, the parallel blade and the intermediate blade have various characteristics. The end of a product having a large size can be punched.
Therefore, there is no need to prepare and prepare various kinds of dies having punches and dies of a size corresponding to the end of the product. There is no need to replace the work.
In addition, in the third aspect, the outer peripheral portion other than the product end is punched by the intermediate blade, and the part from which Thomson has been punched out can be punched out by effectively utilizing the means for punching the product end. .
Further, when each end on the same side of the parallel blade is constituted by a blade portion bent outward, when punching a product that exhibits a linear shape and has little change over the entire length, the embodiment is used. As shown in the above, the intermediate blade can be punched so as to always cross the part punched by the blade (short product), or by expanding the range of intersection to the part punched by the blade Since the degree of freedom of the punching angle of the intermediate blade is increased, the portion to be punched by the intermediate blade can be reliably continued (a long product), which is convenient.
