Description

【０００１】
【発明の属する技術分野】
本発明は、電子部品を基板に実装する電子部品実装システムおよび電子部品実装方法に関するものである。
【０００２】
【従来の技術】
電子部品実装ラインでは、一般に複数の電子部品実装装置を連結して電子部品実装システムを構成することが行われる。このような電子部品実装システムでは、基板はこれらの電子部品実装装置を順次通過し、各電子部品実装装置においては予め当該装置に割付けられた所定量の電子部品のみが実装される。この方法によれば、１つの電子部品実装装置での実装時間を短縮して、タクトタイムを大幅に短縮することができるという利点がある（例えば特許文献１参照）。
【０００３】
上述のような電子部品実装システムでは、各装置間の実装作業の割付は必ずしも固定・不変ではなく、実装作業を実行する過程において割付の変更が必要となる場合がある。例えば１つの基板品種に対して生産開始前のデータ準備作業時に予め設定された初期割付が不適切であった場合には、作業実行過程において各装置間の実装タクトタイムのばらつきが発生するため、このばらつきを極力小さくすることを目的として実装作業の割付を修正する作業が行われる。
【０００４】
この作業においては、作業範囲の変更に伴って変更の対象となる電子部品を収容したパーツフィーダを電子部品実装装置間で移動させる作業とともに、これらの実装作業に対応したデータ類、すなわち各パーツフィーダの配列情報を示すフィーダデータや、基板における実装点の位置を示す実装データなど、部品実装動作に必要なデータを入れ替えるデータ移動作業が必要となる。

【０００６】
【発明が解決しようとする課題】
フィーダデータや実装データなど、電子部品実装システムにおいて使用されるデータは、一般に共通のデータベースに記憶されており、上述のデータ移動作業に際しては、従来はその都度データベースからデータを読み取って必要な編集処理を行った後、各電子部品実装装置に作業実行用のデータとして取り込ませる方法が用いられていた。
【０００７】
しかしながらこのような従来の方法では、移動対象となるデータを各電子部品実装装置に適合させるデータ編集作業が複雑になり、データ移動作業に手間と時間を要するとともに、これらの処理を行うためのデータ処理端末などの専用設備が必要とされていた。このため実装作業の実行過程において作業割付を修正する必要が生じた場合に、迅速にデータ移動処理を行うことが難しく、この作業を簡便な構成で操作性よく実行することが可能な電子部品実装システムが要望されていた。
【０００８】
そこで本発明は、実装作業割付の際のデータ移動処理の操作性を向上させることができる電子部品実装システムおよび電子部品実装方法を提供することを目的とする。
【０００９】
【課題を解決するための手段】
請求項１記載の電子部品実装システムは、複数の電子部品実装装置を連結しそれぞれの電子部品実装装置の制御部をネットワークで相互に接続して構成された電子部品実装システムであって、前記電子部品実装装置が、電子部品を供給するパーツフィーダが複数配列された部品供給部と、前記制御部によって制御され前記部品供給部から電子部品を取り出して基板に移送搭載する機構部と、前記複数の電子部品実装装置の接続構成情報を記憶する接続構成情報記憶部と、前記接続構成情報に基づいて前記電子部品実装システムを構成する他の電子部品実装装置と通信する通信部と、前記部品供給部における電子部品のパーツフィーダの配列を示す部品供給情報と前記基板における電子部品の実装位置を示す実装情報とを関連づけた生産情報のうち、自装置で実行される実装作業範囲についての生産情報である自己生産情報を記憶する自己生産情報記憶部と、前記他の電子部品実装装置に対し当該電子部品実装装置で実行される実装作業についての生産情報である他装置生産情報を要求する指令を生成する他装置生産情報要求指令生成手段と、前記通信部を介して受信した前記他装置生産情報を記憶する他装置生産情報記憶部と、特定された複数の電子部品実装装置の生産情報のうちの特定部分の装置間シフトおよび当該装置間シフト後の前記生産情報の更新を実行することにより、当該複数の電子部品実装装置への実装作業の割付を設定・更新する装置別実装作業割付手段とを備えた。

【００１４】
【発明の実施の形態】
次に本発明の実施の形態を図面を参照して説明する。図１は本発明の一実施の形態の電子部品実装システムの構成図、図２は本発明の一実施の形態の電子部品実装システムの制御系の構成を示すブロック図、図３は本発明の一実施の形態の電子部品実装システムにおけるフィーダ移動処理のフロー図、図４は本発明の一実施の形態の電子部品実装システムの表示画面を示す図、図５は本発明の一実施の形態の電子部品実装システムにおけるフィーダ移動処理時のデータ編集処理を示す説明図である。
【００１５】
まず、図１を参照して電子部品実装システムの構成を説明する。図１において、電子部品実装システム１は、３台の電子部品実装装置２Ａ，２Ｂ，２Ｃ（以下、単に装置Ａ，装置Ｂ、装置Ｃと略記する。）を直列に接続して構成されており、装置Ａ，装置Ｂ、装置Ｃの制御部（図２参照）は、ＬＡＮシステム９によって相互に接続されている。
【００１６】
装置Ａ，装置Ｂ、装置Ｃは、いずれも中央部に水平方向に配列された搬送コンベア３を備えており、これらの装置を直列に接続することにより、各装置の搬送コンベア３は連通した一連の搬送路を形成する。電子部品実装作業時には、上流側から搬入された基板４は装置Ａ，装置Ｂ、装置Ｃの順にこの搬送路を搬送され、各装置において基板４への実装作業が行われる。
【００１７】
各装置は、いずれも搬送コンベア３の両側に複数のパーツフィーダ６を並列状態で装着した部品供給部５が設けられている。部品供給部５には、部品（電子部品）を供給するフィーダであるパーツフィーダ６が装着される位置を特定するアドレス１，２，３・・が設定されている。実装作業においては、後述するフィーダデータに基づいてアドレスが指定され、このアドレスによって特定されるパーツフィーダ６から、機構部７の搭載ヘッド８によって電子部品を取り出し、搬送コンベア３に位置決めされた基板４に移送搭載する。機構部７は、後述する制御部によって制御される。
【００１８】
次に図２を参照して、電子部品実装システムの制御系の構成を説明する。電子部品実装システムを構成する装置Ａ，装置Ｂ、装置Ｃは、いずれも独立した制御機能を備えており、図２に示すように、各装置ごとに、制御部１０、記憶部１１、操作・入力部１３、表示部１４を備えている。これらの各部は通信部１５を介してＬＡＮシステム９に接続されており、後述するように各装置相互間で指令信号の授受ができるようになっている。なお、図２においては、装置Ａ、装置Ｂについてのみ図示している
【００１９】
まず記憶部１１の構成および記憶されるデータの内容について説明する。記憶部１１は、接続構成情報記憶部１１ａ、自己生産情報記憶部１１ｂ、他装置生産情報記憶部１１ｃより構成される。接続構成情報記憶部１１ａは、電子部品実装システム１を構成する複数の電子部品実装装置、すなわちここでは装置Ａ，装置Ｂ、装置Ｃの接続構成情報を記憶する。この接続構成情報により、各装置は電子部品実装システムにおける自装置の位置付けおよび他装置の存在を認識することができ、他装置との通信が可能となる。
【００２０】
自己生産情報記憶部１１ｂは、部品供給情報１２ａ（部品供給部５におけるパーツフィーダ６の配列を示すフィーダデータ）と、実装情報１２ｂ（基板４における電子部品の実装位置を示す実装データ）とを関連づけた生産データ（生産情報）のうち、自装置で実行される実装作業範囲についての生産データである自己生産情報を記憶する。
【００２１】
フィーダデータは、図４に示すように、各装置の部品供給部に設定されたアドレス、すなわちテープフィーダなどのパーツフィーダの装着位置と、各アドレスに割り付けられる部品の種類を示すパーツ名および当該部品の供給に用いられるフィーダタイプを示すデータである。他装置生産情報記憶部１１ｃは、他の電子部品実装装置で実行される実装作業についての生産情報である他装置生産情報を記憶する。他装置生産情報も同様に、部品供給情報１２ａと実装情報１２ｂを組み合わせて構成される。
【００２２】
次に制御部１０の構成について説明する。制御部１０は、排他制御手段１０ａ、他装置生産情報要求指令生成手段１０ｂ、他装置生産情報編集手段１０ｃ、他装置生産情報更新指令生成手段１０ｄ、自己生産情報更新手段１０ｅを含んだ構成となっている。排他制御手段１０ａは電子部品実装システムを構成する他の電子部品実装装置に対し、排他要求指令信号を出力する。これにより、特定処理操作については他の電子部品実装装置による処理実行が禁止され、排他要求指令信号を出力した装置のみが特定処理操作を実行することができる。
【００２３】
他装置生産情報要求指令生成手段１０ｂは、他の電子部品実装装置に対し当該電子部品実装装置で実行される実装作業についての生産情報である他装置生産情報を自装置に送信するよう要求する指令を生成する。この指令を受信した電子部品実装装置は、自装置の自己生産情報記憶部１１ｂに記憶された生産データを、この指令を発信した電子部品実装装置に送る。そして受信した生産データは、当該装置の他装置生産情報記憶部１１ｃに記憶される（図２に示す矢印ａ参照）。
【００２４】
他装置生産情報編集手段１０ｃは他装置生産情報に対して必要な編集処理を行う。すなわち、編集処理の対象となる他装置において生産情報の追加・削除を行う編集処理を、自装置の操作・入力部１３からの入力指令に従って自動的に行う。他装置生産情報更新指令生成手段１０ｄは、編集後の他装置生産情報に基づき、他の電子部品実装装置における自己生産情報を更新すべき旨の指令である他装置生産情報更新指令を生成する。自己生産情報更新手段１０ｅは、自己生産情報に対して必要な編集処理、すなわち編集処理の対象となる自装置において生産情報の追加・削除を行う編集処理を、自装置の操作・入力部１３からの入力指令に従って行う。
【００２５】
このような処理機能を備えた制御部１０は、後述するように、特定された複数の電子部品実装装置の生産情報のうちの特定部分の装置間シフト処理、当該装置間シフト後の生産情報の更新処理をそれぞれを実行することにより、当該複数の電子部品実装装置への実装作業の割付を設定・更新する装置別実装作業割付手段として機能する。
【００２６】
操作・入力部１３はキーボードやマウスなどの入力手段であり、制御部１０に対して各種操作指令やデータの入力を行う。表示部１４は表示パネルなどの表示手段であり、操作・入力部１３による操作入力時の案内画面や、データ表示を行う。通信部１５は通信手段であり、接続構成情報記憶部１１ａに記憶された接続構成情報に基づいて、各装置間の信号やデータの授受を行う。
【００２７】
次に図３を参照して、この電子部品実装システム稼働中におけるフィーダ移動処理について説明する。このフィーダ移動処理は、作業開始前に予め作成され各装置の記憶部に記憶されている生産データに含まれるフィーダデータを変更する操作を行うものであり、作業実行途中において各装置毎のタクトタイムがバランスしていないと判定された場合のラインバランス作業や、突発的な部品切れなどによって実装作業の割付を変更する際などに、必要に応じて随時実行される処理である。
【００２８】
本実施の形態に示す電子部品実装システムにおいては、このフィーダ移動処理を電子部品実装システムを構成するいずれの装置によっても実行することが可能となっており、図３に示すフローでは、フィーダの装置間シフトの対象となっている装置Ａによってこの処理を実行する例を示している。すなわち、この例では装置Ａがデータのシフト元であり、装置Ｂがデータがシフトされるシフト先となっている。
【００２９】
まず図３において、装置Ａにおいて、操作者が操作・入力部１３を操作してフィーダ移動画面を開く（ＳＴ１）（図４参照）。そして、排他制御手段１０ａにより他の全装置に対して排他要求指令を送信する（ＳＴ２）。これにより、装置Ａ以外の他の装置による生産データの改変処理が禁止される。次いで、他装置生産情報要求指令生成手段１０ｂにより指令を生成し、通信部１５を介して、装置Ａから装置Ｂに対して他装置生産情報を要求する指令であるフィーダデータ要求指令を送信する（ＳＴ３）。このフィーダデータ要求指令を受けて、装置Ｂは自己生産情報記憶部１１ｂに記憶されているフィーダデータを、通信部１５を介して装置Ａへ送信する（ＳＴ４）。受信した装置Ａでは、受信したフィーダデータを他装置生産情報記憶部１１ｃに記憶する（ＳＴ５）。
【００３０】
次にデータ編集処理が実行される。まず装置Ａにおいて、自己生産情報記憶部１１ｂおよび他装置生産情報記憶部１１ｃから読み取った装置Ａと装置Ｂのフィーダデータを、表示部１４の１画面に表示する（ＳＴ６）。すなわち、図４に示すように、フィーダ移動画面を表す表示画面２０には、それぞれ装置Ａ、装置Ｂのフィーダデータを示すデータウインドウ２１Ａ，２１Ｂが開かれる。ここでは表示部１４は、特定された複数の電子部品実装装置の生産情報を同一表示画面に表示する表示手段として機能している。
【００３１】
そしてこの表示画面上において、操作者がフィーダデータ（部品供給情報）の一部を装置Ａから装置Ｂへマウス操作によって画面上で移動させ、確認ボタンをクリックする（ＳＴ７）。すなわち、ウインドウ２１Ａ上で装置Ａにおいて移動対象となる特定部分のフィーダデータを指定し、次いでこのフィーダデータをウインドウ２１Ｂまでドラッグして装置Ｂの特定アドレスに貼付ける操作を行う。ここでは、当初装置Ａに割り付けられていた部品名ｂの部品を装置Ｂのアドレス１０に移動させる例を示している。
【００３２】
そして装置Ａは、装置Ｂへ移動されたフィーダに関する情報およびこれに関する実装位置のデータ（実装情報１２ｂ）を、自己生産情報記憶部１１ｂから読み取り送信する（ＳＴ８）。この実装位置についてのデータの送信は、操作者の画面操作を要することなく他装置生産情報編集手段１０ｃによって自動的に行われる。すなわち図５に例示するように、装置Ａから装置Ｂに部品ｂをシフトする操作を行うことにより、予め部品ｂに対応して装置Ａに記憶されていた実装情報（実装位置のＸ，Ｙ、θ座標やノズル種類を示す実装データ）が、部品ｂの移動にリンクして装置Ｂに移動する。
【００３３】
したがって装置別実装作業割付手段としての制御部１０は、装置間シフトの対象となる特定部分の部品供給情報を表示手段の表示に基づいて指定する入力手段と、指定されたフィーダデータの移動に伴って、このフィーダデータと対応関係にある実装位置のデータを追従移動させる移動リンク手段とを有するものとなっている。
【００３４】
すなわち、電子部品実装システムによる電子部品実装方法においては、装置別実装作業割付処理の実行に際し、複数の電子部品実装装置の生産情報を表示手段によって同一表示画面に表示させ、装置間シフトの対象となる特定部分の部品供給情報を表示手段の表示に基づいて指定し、指定された部品供給情報の移動に伴ってこの部品供給情報と対応関係にある実装情報を移動リンク手段によって追従移動させる形態となっている。
【００３５】
データを受信した装置Ｂは、受信した移動対象のフィーダに関するデータを、自己生産情報更新手段１０ｅによって新たな自己生産情報として自己生産情報記憶部１１ｂに記憶する（ＳＴ９）。これにより、装置Ｂの自己生産情報が更新される。そして装置Ｂは、他装置生産情報更新指令生成手段１０ｄによって指令を生成し、通信部１５を介して装置Ａへ他装置生産情報更新指令であるフィーダデータ更新指令を送信する（ＳＴ１０）。このフィーダデータ更新指令を受信すると、装置Ａは移動したフィーダに関するフィーダデータを、自己生産情報更新手段１０ｅによって自己生産データから削除する（ＳＴ１１）。これにより、装置Ａの自己生産情報が更新される。
【００３６】
すなわち上記処理により、フィーダの移動元の装置Ａ、移動先の装置Ｂのいずれにおいても、フィーダの移動に伴うデータの装置間シフトおよび対応する生産データの更新が完了する。ここでは、データのシフト先の装置から先に更新処理が行われるようになっている。そして、装置Ａにおいて操作者がフィーダ移動画面を閉じ（ＳＴ１２）、さらに装置Ａから他の全装置に排他解除指令を送信して（ＳＴ１３）、フィーダ移動処理を終了する。
【００３７】
なお図３では、フィーダの移動元の装置Ａにおいてフィーダ移動処理のデータ操作を行う例を示しているが、このデータ操作はフィーダの移動先である装置Ｂで行ってもよいし、またはフィーダの移動に直接関係しない装置Ｃによってこのデータ操作を行ってもよい。すなわち、本電子部品実装システムによる電子部品実装方法は、特定された複数の電子部品実装装置への実装作業の割付を設定・更新する装置別実装作業割付処理の実行に際し、これらの複数の電子部品実装装置の生産情報のうちの特定部分の装置間シフトおよび当該装置間シフト後の生産情報の更新を、電子部品実装システムを構成する複数の電子部品実装装置のうちのいずれか１つによって実行する形態となっている。
【００３８】
上記説明したように、本実施の形態に示す電子部品実装システムは、特定された複数の電子部品実装装置への実装作業の割付を設定・更新する装置別実装作業割付処理の実行に際し、これらの複数の電子部品実装装置の生産情報のうちの特定部分の装置間シフトおよび当該装置間シフト後の生産情報の更新を、電子部品実装システムを構成する複数の電子部品実装装置のうちのいずれか１つで実行可能な構成としたものである。
【００３９】
これにより、作業実行過程において各装置間の実装タクトタイムのばらつきを修正する目的や、部品切れなど突発的な事態に対応する目的で行われる実装作業の割付変更作業において、必要とされるデータ移動作業を操作性よく実行することができる。
【００４０】
【発明の効果】
本発明によれば、特定された複数の電子部品実装装置への実装作業の割付を設定・更新する装置別実装作業割付処理の実行に際し、これらの複数の電子部品実装装置の生産情報のうちの特定部分の装置間シフトおよび当該装置間シフト後の前記生産情報の更新を、電子部品実装システムを構成する複数の電子部品実装装置のうちのいずれか１つで実行可能な構成としたので、実装作業割付の際のデータ移動処理の操作性を向上させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic component mounting system and an electronic component mounting method for mounting an electronic component on a substrate.
[0002]
[Prior art]
In an electronic component mounting line, generally, a plurality of electronic component mounting apparatuses are connected to form an electronic component mounting system. In such an electronic component mounting system, the board sequentially passes through these electronic component mounting devices, and in each electronic component mounting device, only a predetermined amount of electronic components previously allocated to the device are mounted. According to this method, there is an advantage that the mounting time in one electronic component mounting apparatus can be reduced, and the tact time can be significantly reduced (for example, see Patent Document 1).
[0003]
In the electronic component mounting system as described above, the allocation of the mounting operation between the devices is not necessarily fixed or invariable, and the allocation may need to be changed in the process of performing the mounting operation. For example, if the initial assignment set in advance during the data preparation work before the start of production for one board type is inappropriate, a variation in the mounting tact time between devices occurs in the work execution process. An operation of correcting the assignment of the mounting operation is performed for the purpose of minimizing the variation.
[0004]
In this work, a part feeder accommodating an electronic component to be changed in accordance with a change in the work range is moved between electronic component mounting apparatuses, and data corresponding to the mounting work, that is, each part feeder is moved. It is necessary to perform a data transfer operation for exchanging data necessary for the component mounting operation, such as feeder data indicating the array information and mounting data indicating the position of the mounting point on the board.
[0005]
[Patent Document 1]
JP 2000-49498 A
[Problems to be solved by the invention]
Data used in the electronic component mounting system, such as feeder data and mounting data, is generally stored in a common database. When performing the above-described data movement work, conventionally, data is read from the database each time and necessary editing processing is performed. After that, a method has been used in which each electronic component mounting apparatus takes in the data as work execution data.
[0007]
However, in such a conventional method, the data editing work for adapting the data to be moved to each electronic component mounting apparatus becomes complicated, and the data moving work requires time and effort, and data for performing these processes is required. Special equipment such as a processing terminal was required. For this reason, when it becomes necessary to correct the work assignment in the course of performing the mounting work, it is difficult to quickly perform the data movement processing, and the electronic component mounting can perform this work with a simple configuration and good operability. A system was desired.
[0008]
Therefore, an object of the present invention is to provide an electronic component mounting system and an electronic component mounting method that can improve the operability of data movement processing at the time of mounting work allocation.

[0027]
Next, the feeder moving process during the operation of the electronic component mounting system will be described with reference to FIG. This feeder moving process is an operation for changing feeder data included in production data created in advance and stored in the storage unit of each device before the start of work, and the tact time of each device during execution of the work. This is a process that is executed as needed, for example, when it is determined that the balance is not balanced, when the allocation of the mounting operation is changed due to sudden component shortage, or the like.
[0028]
In the electronic component mounting system shown in the present embodiment, the feeder moving process can be executed by any device constituting the electronic component mounting system. In the flow shown in FIG. An example is shown in which this processing is executed by the device A to be shifted. That is, in this example, the device A is a data shift source, and the device B is a shift destination to which data is shifted.
[0029]
First, in FIG. 3, in the device A, the operator operates the operation / input unit 13 to open the feeder moving screen (ST1) (see FIG. 4). Then, the exclusion control unit 10a transmits an exclusion request command to all other devices (ST2). As a result, a process of modifying the production data by a device other than the device A is prohibited. Next, a command is generated by the other device production information request command generation means 10b, and a feeder data request command, which is a command for requesting other device production information, is transmitted from the device A to the device B via the communication unit 15 ( ST3). In response to the feeder data request command, the device B transmits the feeder data stored in the self-production information storage unit 11b to the device A via the communication unit 15 (ST4). The receiving apparatus A stores the received feeder data in the other apparatus production information storage unit 11c (ST5).

That is, as shown in FIG. 4, data windows 21A and 21B showing feeder data of the apparatuses A and B are opened on the display screen 20 representing the feeder moving screen. Here, the display unit 14 functions as a display unit that displays the production information of the specified electronic component mounting apparatuses on the same display screen.
[0031]
Then, on this display screen, the operator moves a part of the feeder data (component supply information) from the apparatus A to the apparatus B on the screen by operating the mouse, and clicks a confirmation button (ST7). That is, the user specifies the feeder data of the specific portion to be moved in the device A on the window 21A, and then drags the feeder data to the window 21B and pastes the data to the specific address of the device B. Here, an example is shown in which a component having a component name b initially assigned to the device A is moved to the address 10 of the device B.
[0032]
Then, the apparatus A reads information on the feeder moved to the apparatus B and data on the mounting position (mounting information 12b) relating to the information from the self-production information storage unit 11b and transmits it (ST8). The transmission of the data on the mounting position is automatically performed by the other apparatus production information editing means 10c without requiring the operator to operate the screen. That is, as illustrated in FIG. 5, by performing an operation of shifting the component b from the device A to the device B, the mounting information (X, Y, The θ coordinate and the mounting data indicating the nozzle type move to the device B in link with the movement of the component b.
[0033]
Therefore, the control unit 10 as a device-specific mounting work allocating unit includes an input unit that specifies, based on the display on the display unit, component supply information of a specific portion to be shifted between the devices, and a movement of the specified feeder data.

Has become.
[0035]
The device B that has received the data stores the received data regarding the feeder to be moved as new self-production information in the self-production information storage unit 11b by the self-production information updating unit 10e (ST9). Thereby, the self-production information of the device B is updated. Then, the device B generates a command by the other device production information update command generation means 10d, and transmits a feeder data update command, which is another device production information update command, to the device A via the communication unit 15 (ST10). Upon receiving this feeder data update command, the apparatus A deletes the feeder data relating to the moved feeder from the self-production data by the self-production information updating means 10e (ST11). Thereby, the self-production information of the device A is updated.
[0036]
That is, by the above-described processing, in each of the source device A and the destination device B of the feeder, the shift of the data between the devices due to the movement of the feeder and the update of the corresponding production data are completed. Here, the updating process is performed first from the device to which the data is shifted. Then, in the apparatus A, the operator closes the feeder movement screen (ST12), transmits an exclusion release command from the apparatus A to all other apparatuses (ST13), and ends the feeder movement processing.
[0037]
Note that FIG. 3 shows an example in which the data operation of the feeder moving process is performed in the device A that is the source of the feeder. However, this data operation may be performed in the device B that is the destination of the feeder, or This data manipulation may be performed by the device C not directly related to the movement.
