Description

本発明は、１台又は複数台の実装機からなる実装機ラインに回路基板を搬送して該回路基板に複数の部品を実装して部品実装基板を生産する部品実装基板生産方法及び部品実装基板生産システムに関する発明である。   The present invention relates to a component mounting board production method and a component mounting board for producing a component mounting board by transporting a circuit board to a mounting machine line composed of one or a plurality of mounting machines and mounting a plurality of components on the circuit board. It is an invention related to a production system.

例えば、特許文献１（特開２００８−２７０３３７号公報）に示すように、回路基板の搬送経路に沿って複数台の実装機を配列して各実装機に回路基板を順次搬送して該回路基板に複数の部品を実装するようにしたものがある。このような実装機ラインの構成で、実装機ラインのフィーダ搭載数が回路基板に実装する部品の種類数よりも少ない場合は、回路基板に全ての部品を実装することができないため、実装機ラインに実装機を増設してフィーダ搭載数を増加させる必要がある。   For example, as shown in Patent Document 1 (Japanese Patent Laid-Open No. 2008-270337), a plurality of mounting machines are arranged along a circuit board transport path, and the circuit boards are sequentially transported to the mounting machines. In some cases, a plurality of parts are mounted. In such a mounting machine line configuration, if the number of feeders mounted on the mounting machine line is smaller than the number of types of parts mounted on the circuit board, it is impossible to mount all the parts on the circuit board. It is necessary to increase the number of feeders by adding more mounting machines.

しかし、実装機ラインの設置スペースの制約から実装機を増設できない場合があり、この場合には、回路基板に実装する部品の種類数が実装機ラインのフィーダ搭載数よりも多い生産には対応できない。   However, there may be cases where the number of mounting machines cannot be increased due to restrictions on the mounting space of the mounting machine line. In this case, it is not possible to handle production in which the number of types of components mounted on the circuit board is greater than the number of feeders mounted on the mounting machine line. .

また、実装機を増設して実装機ラインの編成を変更する作業はかなり手間がかかるため、生産数が少ない多品種少量生産では、実装機を増設して実装機ラインの編成を変更すると、基板１枚当たりの生産コストが大幅に増加することは避けられない。   In addition, since it takes a lot of work to change the assembly of the mounting machine line by adding mounting machines, in the case of low-volume, high-mix low-volume production, changing the mounting machine line and changing the mounting machine line organization It is inevitable that the production cost per sheet will greatly increase.

尚、特許文献２（特開２００４−１２８２４５号公報）には、実装機ラインに２本の搬送路を設けて、一方の搬送路で回路基板を順方向に搬送して該回路基板に部品を実装した後、搬送方向を反転させて、他方の搬送路で回路基板を逆方向に搬送して該回路基板に部品を実装して、基板搬入側と同一側から回路基板を回収する構成が記載されている。しかし、この構成でも、回路基板に実装する部品の種類数が実装機ラインのフィーダ搭載数よりも多い生産には対応できない。   In Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-128245), two transport paths are provided on the mounting machine line, and the circuit board is transported in the forward direction on one transport path, and components are mounted on the circuit board. After mounting, the configuration is described in which the transport direction is reversed, the circuit board is transported in the opposite direction on the other transport path, the components are mounted on the circuit board, and the circuit board is collected from the same side as the board carry-in side. Has been. However, even this configuration cannot cope with production in which the number of types of components mounted on the circuit board is larger than the number of feeders mounted on the mounting machine line.

本発明はこのような事情を考慮してなされたものであり、従ってその目的は、回路基板に実装する部品の種類数が実装機ラインのフィーダ搭載数よりも多い場合でも、実装機を増設することなく、生産が可能となり、多様な生産を低コスト・省スペースで実現できる部品実装基板生産方法及び部品実装基板生産システムを提供することにある。   The present invention has been made in view of such circumstances. Therefore, the object of the present invention is to increase the number of mounting machines even when the number of types of components mounted on the circuit board is larger than the number of feeders mounted on the mounting machine line. Accordingly, it is an object of the present invention to provide a component mounting board production method and a component mounting board production system that enable production and realize various production at low cost and space saving.

上記課題を解決するために、本発明は、１台又は複数台の実装機からなる実装機ラインに回路基板を搬送して該回路基板に所定数の部品を実装して部品実装基板を生産する部品実装基板生産方法及び部品実装基板生産システムであって、前記実装機ラインのフィーダ搭載数が前記回路基板に実装する前記所定数の部品の種類数よりも少ない場合に、１台又は複数台の実装機からなる実装機ラインに順方向に回路基板を搬送して該回路基板に前記所定数の部品のうちの一部の部品を実装する順方向の実装作業と、前記実装機ラインに逆方向に前記回路基板を搬送して該回路基板に前記所定数の部品のうちの他の部品を実装する逆方向の実装作業と、前記回路基板の搬送方向を反転させる前に前記実装機にセットされているフィーダを搬送方向反転後の実装作業で実装する部品を供給するフィーダに取り替えるフィーダ取替作業とを前記回路基板に前記所定数の部品を実装するまで繰り返すようにしたものである。
In order to solve the above problems, the present invention produces a component mounting board by transporting a circuit board to a mounting machine line composed of one or more mounting machines and mounting a predetermined number of components on the circuit board. In the component mounting board production method and the component mounting board production system, when the number of feeders mounted on the mounting machine line is smaller than the number of types of the predetermined number of components to be mounted on the circuit board, A forward mounting operation in which a circuit board is transported in a forward direction to a mounting machine line composed of mounting machines and a part of the predetermined number of parts is mounted on the circuit board, and a reverse direction is applied to the mounting machine line. In the reverse mounting operation of transporting the circuit board and mounting the other parts of the predetermined number of parts on the circuit board, and before reversing the transport direction of the circuit board, set in the mounting machine Feeding direction of feeder It is obtained so as to repeat the feeder replacement work to replace a feeder for supplying a component to be mounted in mounting work after rolling until mounting the predetermined number of components on the circuit board.

本発明のように、順方向の実装作業→フィーダ取替作業→逆方向の実装作業→フィーダ取替作業→順方向の実装作業→……の順序で各方向の実装作業とフィーダ取替作業とを交互に行うようにすれば、回路基板に実装する部品の種類数が実装機ラインのフィーダ搭載数よりも多い場合でも、実装機を増設することなく、生産が可能となり、多様な生産を低コスト・省スペースで実現することができる。   Like the present invention, the forward mounting work → feeder replacement work → reverse mounting work → feeder replacement work → forward mounting work → ... If the number of parts to be mounted on the circuit board is larger than the number of feeders mounted on the mounting machine line, production can be performed without adding mounting machines, thus reducing diverse production. It can be realized at low cost and space.

この場合、実装機ラインの搬入側と搬出側に、搬送されてきた生産途中の回路基板を一時的にストック又は待機させて搬送方向反転後に該生産途中の回路基板を１枚ずつ実装機ラインに搬送するバッファ又はコンベアを設けるようにすると良い。このようにすれば、いずれかの方向の実装作業が終わって作業者がフィーダ取替作業を行った後に、直ちにバッファ又はコンベアから生産途中の回路基板を１枚ずつ自動的に実装機ラインに搬送して次の実装作業を行うことができる。   In this case, the circuit boards in the middle of production that have been transported are temporarily stocked or waited on the carry-in side and the carry-out side of the mounting machine line, and the circuit boards in the middle of production are turned into the mounting machine line one by one after reversing the transport direction. It is advisable to provide a buffer or conveyor for conveyance. In this way, after the mounting work in either direction is finished and the operator performs the feeder replacement work, the circuit boards in production are automatically transferred one by one from the buffer or conveyor to the mounting machine line immediately. Then, the following mounting work can be performed.

更に、順方向又は逆方向の実装作業を終了して回路基板の搬送方向を反転させる前に、フィーダ取替作業を行うように作業者に表示及び／又は音声で指示するようにすると良い。これにより、各方向の実装作業が終了する毎に、表示及び／又は音声による指示に従って作業者に直ちにフィーダ取替作業を行わせることができる。   Furthermore, it is preferable to display and / or instruct the worker to perform the feeder replacement work before the forward or reverse mounting work is finished and the conveyance direction of the circuit board is reversed. Thereby, every time the mounting operation in each direction is completed, the operator can immediately perform the feeder replacement operation in accordance with the display and / or voice instructions.

以下、本発明を実施するための形態を具体化した２つの実施例１，２を説明する。   Hereinafter, two Examples 1 and 2 which embody the form for implementing this invention are demonstrated.

本発明の実施例１を図１及び図２に基づいて説明する。
実装機ライン１１は、１台又は複数台の実装機１２からなり、各実装機１２に、複数のフィーダ１３が着脱可能にセットされたフィーダパレット１４が交換可能に取り付けられている。実装機ライン１１は、回路基板１５の搬送方向を順方向と逆方向に切り替え可能に構成されていると共に、該実装機ライン１１の搬入側と搬出側に、それぞれバッファ１６，１７が設置され、実装機ライン１１を通過した生産途中の回路基板１５を一時的にバッファ１６，１７にストックして搬送方向反転後に該生産途中の回路基板１５をバッファ１６，１７から１枚ずつ実装機ライン１１に搬送するようにしている。各バッファ１６，１７は、搬入した生産途中の回路基板１５を上下動させて立体的にストックする機能と、該回路基板１５を１枚ずつ搬入・搬出する機能を備えている。 A first embodiment of the present invention will be described with reference to FIGS.
The mounting machine line 11 includes one or a plurality of mounting machines 12, and a feeder pallet 14 in which a plurality of feeders 13 are detachably set is attached to each mounting machine 12 in a replaceable manner. The mounting machine line 11 is configured so that the transport direction of the circuit board 15 can be switched between the forward direction and the reverse direction, and buffers 16 and 17 are installed on the loading side and the unloading side of the mounting machine line 11, respectively. The circuit boards 15 in the middle of production that have passed through the mounting machine line 11 are temporarily stocked in the buffers 16 and 17, and after the direction of conveyance is reversed, the circuit boards 15 in the middle of production are transferred from the buffers 16 and 17 to the mounting machine line 11 one by one. I am trying to carry it. Each of the buffers 16 and 17 has a function of moving up and down the circuit board 15 in the middle of production and stocking it three-dimensionally, and a function of loading and unloading the circuit boards 15 one by one.

回路基板１５とフィーダパレット１４には、それぞれ識別情報（ＩＤ）を表示する識別部が設けられ、実装機１２のカメラ１８（例えば回路基板１５の基準位置マークを撮像するマークカメラ）で回路基板１５のＩＤを撮像して読み取ることで生産を管理するようになっている。また、実装機１２のマークカメラ等のカメラ１８でフィーダパレット１４のＩＤを撮像して読み取ることで、現在の生産工程（ジョブ）に対応したフィーダパレット１４（フィーダ１３）が実装機１２に取り付けられているか否かを判定する。   The circuit board 15 and the feeder pallet 14 are each provided with an identification unit for displaying identification information (ID), and the circuit board 15 is mounted by a camera 18 of the mounting machine 12 (for example, a mark camera for imaging a reference position mark of the circuit board 15). Production is managed by capturing and reading the ID of the image. Also, the feeder pallet 14 (feeder 13) corresponding to the current production process (job) is attached to the mounting machine 12 by imaging and reading the ID of the feeder pallet 14 with a camera 18 such as a mark camera of the mounting machine 12. It is determined whether or not.

回路基板１５に実装する部品の種類数が実装機ライン１１のフィーダ１３の搭載数よりも多い場合（つまり回路基板１５を実装機ライン１１に順方向に流しただけでは回路基板１５に全ての部品を実装できない場合）には、部品実装基板を生産するジョブを複数に分割し、実装機ライン１１に順方向に回路基板１５を搬送して該回路基板１５に一部の部品を実装する順方向の実装作業と、実装機ライン１１に逆方向に回路基板１５を搬送して該回路基板１５に他の部品を実装する逆方向の実装作業と、回路基板１５の搬送方向を反転させる前に実装機１２に取り付けられているフィーダパレット１４を搬送方向反転後の実装作業で実装する部品を供給するフィーダ１３をセットしたフィーダパレット１４に取り替えるフィーダ取替作業とを回路基板１５に所定数の部品を実装するまで繰り返すようにしている。   When the number of types of components to be mounted on the circuit board 15 is greater than the number of feeders 13 mounted on the mounting machine line 11 (that is, all the components on the circuit board 15 just by flowing the circuit board 15 forward in the mounting machine line 11) If the circuit board 15 is not mounted, the job for producing the component mounting board is divided into a plurality of parts, the circuit board 15 is transported to the mounting machine line 11 in the forward direction, and a part of the circuit board 15 is mounted in the forward direction. Mounting work, reverse mounting work for transporting the circuit board 15 to the mounting machine line 11 in the reverse direction and mounting other components on the circuit board 15, and mounting before reversing the transport direction of the circuit board 15 The feeder pallet 14 attached to the machine 12 is replaced with a feeder pallet 14 in which the feeder pallet 14 for supplying components to be mounted in the mounting operation after the reversal of the conveyance direction is set. So that repeated until implementing a predetermined number of components on a substrate 15.

例えば、部品実装基板を生産するジョブを３つに分割する場合は、順方向の実装作業（ジョブ１）→フィーダ取替作業→逆方向の実装作業（ジョブ２）→フィーダ取替作業→順方向の実装作業（ジョブ３）の順序で各方向の実装作業とフィーダ取替作業とを交互に行う。実装機ライン１１の制御装置は、図２の生産管理プログラムを実行して部品実装基板を次のようにして生産する。まず、ステップ１０１で、回路基板１５を実装機ライン１１に順方向に搬送して、次のステップ１０２で、該回路基板１５に一部の部品を実装する順方向の実装作業（ジョブ１）を行い、部品を実装した生産途中の回路基板１５を搬出側のバッファ１７にストックする。次のステップ１０３で、順方向の実装作業（ジョブ１）を終了した基板枚数が予め設定された所定枚数に達したか否かを判定し、順方向の実装作業（ジョブ１）を終了した基板枚数が所定枚数に達するまで、順方向の搬送と実装作業（ジョブ１）を繰り返す（ステップ１０１、１０２）。   For example, when dividing a job for producing a component mounting board into three, forward mounting work (job 1) → feeder replacement work → reverse mounting work (job 2) → feeder replacement work → forward direction The mounting work in each direction and the feeder replacement work are alternately performed in the order of the mounting work (job 3). The control device of the mounting machine line 11 executes the production management program of FIG. 2 to produce a component mounting board as follows. First, in step 101, the circuit board 15 is transferred to the mounting machine line 11 in the forward direction, and in the next step 102, a forward mounting operation (job 1) for mounting some components on the circuit board 15 is performed. Then, the circuit board 15 in the middle of production on which components are mounted is stocked in the buffer 17 on the carry-out side. In the next step 103, it is determined whether or not the number of substrates that have completed the forward mounting operation (job 1) has reached a predetermined number, and the substrate that has completed the forward mounting operation (job 1). The forward conveyance and the mounting operation (job 1) are repeated until the number reaches the predetermined number (steps 101 and 102).

そして、順方向の実装作業（ジョブ１）を終了した基板枚数が所定枚数に達した時点で、ステップ１０４に進み、実装機１２に取り付けられているフィーダパレット１４を、次のジョブ２で実装する部品を供給するフィーダ１３をセットしたフィーダパレット１４に交換するように作業者に表示及び／又は音声で指示し、作業者がフィーダパレット１４の交換作業を行うまで待機する（ステップ１０５）。   When the number of substrates that have completed the forward mounting operation (job 1) reaches a predetermined number, the process proceeds to step 104, and the feeder pallet 14 attached to the mounting machine 12 is mounted in the next job 2. The operator is instructed by display and / or voice to replace the feeder 13 for supplying the parts with the feeder pallet 14 set, and waits until the worker performs the replacement operation of the feeder pallet 14 (step 105).

この際、フィーダパレット１４を取り替えることで、実装機１２に部品を供給する多数のフィーダ１３を一括して取り替えることができるため、フィーダ取替作業を能率良く行うことができる。尚、取り替え対象となるフィーダ１３の数が少ない場合は、フィーダパレット１４を取り替えずに、取り替え対象となるフィーダ１３を個々に取り替えるようにしても良い。   At this time, by replacing the feeder pallet 14, a large number of feeders 13 that supply components to the mounting machine 12 can be replaced at a time, so that the feeder replacement operation can be performed efficiently. When the number of feeders 13 to be replaced is small, the feeders 13 to be replaced may be replaced individually without replacing the feeder pallet 14.

その後、作業者がフィーダパレット１４の交換作業（フィーダ取替作業）を行った時点で、ステップ１０６に進み、搬出側のバッファ１７にストックされた生産途中の回路基板１５を１枚ずつ実装機ライン１１に逆方向に搬送して、次のステップ１０７で、該回路基板１５に他の部品を実装する逆方向の実装作業（ジョブ２）を行い、部品を実装した生産途中の回路基板１５を搬入側のバッファ１６にストックする。次のステップ１０８で、逆方向の実装作業（ジョブ２）を終了した基板枚数が予め設定された所定枚数に達したか否かを判定し、逆方向の実装作業（ジョブ２）を終了した基板枚数が所定枚数に達するまで、逆方向の搬送と実装作業（ジョブ２）を繰り返す（ステップ１０６、１０７）。   After that, when the worker performs the replacement work of the feeder pallet 14 (feeder replacement work), the process proceeds to step 106, and the circuit boards 15 in the production process stocked in the buffer 17 on the carry-out side are mounted one by one. 11 in the reverse direction, and in the next step 107, a reverse mounting operation (job 2) for mounting other components on the circuit board 15 is performed, and the circuit board 15 in the middle of production in which the components are mounted is carried in Stock in side buffer 16. In the next step 108, it is determined whether or not the number of substrates that have completed the reverse mounting operation (job 2) has reached a predetermined number, and the substrate that has completed the reverse mounting operation (job 2). The reverse conveyance and mounting operation (job 2) are repeated until the number reaches the predetermined number (steps 106 and 107).

そして、逆方向の実装作業（ジョブ２）を終了した基板枚数が所定枚数に達した時点で、ステップ１０９に進み、次のジョブ３に対応したフィーダパレット１４に交換するように作業者に表示及び／又は音声で指示し、作業者がフィーダパレット１４の交換作業を行うまで待機する（ステップ１１０）。   Then, when the number of substrates for which the reverse mounting operation (job 2) has been completed reaches a predetermined number, the process proceeds to step 109 to display to the operator to replace the feeder pallet 14 corresponding to the next job 3. Instruct by voice and wait until the operator performs replacement work of the feeder pallet 14 (step 110).

その後、作業者がフィーダパレット１４の交換作業を行った時点で、ステップ１１１に進み、搬入側のバッファ１６にストックされた生産途中の回路基板１５を１枚ずつ実装機ライン１１に順方向に搬送して、次のステップ１１２で、該回路基板１５に残りの部品を実装する順方向の実装作業（ジョブ３）を行う。これにより、所定数の部品が実装された回路基板１５を実装機ライン１１から搬出して後工程に流す（ステップ１１３）。   Thereafter, when the operator performs the replacement work of the feeder pallet 14, the process proceeds to Step 111, and the circuit boards 15 in the process of being stocked stored in the buffer 16 on the carry-in side are transferred to the mounting machine line 11 one by one in the forward direction. Then, in the next step 112, a forward mounting operation (job 3) for mounting the remaining components on the circuit board 15 is performed. As a result, the circuit board 15 on which a predetermined number of components are mounted is unloaded from the mounting machine line 11 and passed to the subsequent process (step 113).

以上説明した本実施例１では、順方向の実装作業（ジョブ１）→フィーダ取替作業→逆方向の実装作業（ジョブ２）→フィーダ取替作業→順方向の実装作業（ジョブ３）の順序で各方向の実装作業とフィーダ取替作業とを交互に行うようにしたので、回路基板１５に実装する部品の種類数が実装機ライン１１のフィーダ１３の搭載数よりも多い場合でも、実装機１２を増設することなく、生産が可能となり、多様な生産を低コスト・省スペースで実現することができる。   In the first embodiment described above, the order of forward mounting work (job 1) → feeder replacement work → reverse mounting work (job 2) → feeder replacement work → forward mounting work (job 3). Thus, the mounting operation in each direction and the feeder replacement operation are alternately performed. Therefore, even if the number of types of components mounted on the circuit board 15 is larger than the number of feeders 13 mounted on the mounting machine line 11, the mounting machine Production is possible without adding 12 and various production can be realized at low cost and space saving.

尚、実装機ライン１１を複数台の実装機で構成している場合は、実装機ライン１１の搬入側と搬出側に加え、実装機ライン１１中の適宜の実装機間（１か所又は複数箇所）にそれぞれバッファを設け、それらのバッファ間にて前記生産工程を行っても同様の効果を得ることができる。   When the mounting machine line 11 is composed of a plurality of mounting machines, in addition to the loading side and the unloading side of the mounting machine line 11, between the appropriate mounting machines in the mounting machine line 11 (one or a plurality of mounting machines). The same effect can be obtained even if buffers are provided in the respective locations) and the production process is performed between the buffers.

上記実施例１では、実装機ライン１１の搬入側と搬出側に、各方向の実装作業で部品を実装した生産途中の回路基板１５を一時的にストックするバッファ１６，１７を設置したが、図３に示す本発明の実施例２では、実装機ライン２０の搬入側と搬出側に設けたコンベア２１，２２若しくは実装機１、実装機３を使用して、各方向の実装作業で部品を実装した生産途中の回路基板１５を実装機ライン２０の搬入側と搬出側のコンベア２１，２２若しくは実装機１、実装機３内のコンベア上にて一時的に待機させ、いずれかの方向の実装作業が終わって作業者がフィーダ取替作業を行った後に、直ちに実装機ライン２０の搬入側と搬出側のコンベア２１，２２若しくは実装機１、実装機３内のコンベアから生産途中の回路基板１５を１枚ずつ自動的に実装機ライン２０に搬送して次の実装作業を行うようにしている。   In the first embodiment, the buffers 16 and 17 for temporarily stocking the circuit board 15 in the middle of production in which components are mounted by mounting work in each direction are installed on the carry-in side and the carry-out side of the mounter line 11. In the second embodiment of the present invention shown in FIG. 3, the components are mounted by mounting work in each direction using the conveyors 21 and 22 or the mounting machine 1 and the mounting machine 3 provided on the loading side and the unloading side of the mounting machine line 20. The circuit board 15 in the middle of production is temporarily put on the conveyors 21 and 22 on the carry-in side and the carry-out side of the mounting machine line 20 or on the conveyors in the mounting machine 1 and the mounting machine 3, and mounting work in either direction After the operator completes the feeder replacement operation, the circuit board 15 in the middle of production is immediately transferred from the conveyors 21 and 22 on the loading side and the unloading side of the mounting machine line 20 or the conveyors in the mounting machine 1 and the mounting machine 3. One by one To be transported to the mounting machine line 20 and to perform the following mounting operation.

以上のように構成した本実施例２でも、前述した実施例１と同様の効果を得ることができる。   In the second embodiment configured as described above, the same effect as that of the first embodiment can be obtained.
