Description
以下に示す実施形態は、技術的思想を具体化するための構成や方法を例示するものであり、各構成部品の材質、形状、構造、配置、寸法等を下記のものに限定するものではない。なお、説明を簡単かつ明確にするために、図面に示される構成要素は必ずしも一定の縮尺で描かれていない。添付の図面は、本開示の実施形態を例示するに過ぎず、本開示を制限するものとみなされるべきではない。本開示における「第1」、「第2」、「第3」等の用語は、単に対象物を区別するために用いられており、対象物を順位づけするものではない。
図1に示すように、レーザ加工装置10は、コントローラユニット11と、光源ユニット12と、ヘッドユニット13とを有している。光源ユニット12は、第1電気ケーブル81と光ファイバケーブルFLとによりヘッドユニット13に接続されている。また、光源ユニット12は、第2電気ケーブル82によりコントローラユニット11に接続されている。第1電気ケーブル81は、第1電源ケーブルSP1と第1信号ケーブルSL1とから構成されている。第2電気ケーブル82は、第2電源ケーブルSP2と第2信号ケーブルSL2とから構成されている。コントローラユニット11は、電源ケーブル15によりAC電源が供給される。
図1、図3に示すように、光源ユニット12は、略直方体状の筐体12aを有している。
光源駆動回路43は、レーザ光源44を駆動するための回路である。
図1、図3に示すように、ヘッドユニット13は、略直方体状の筐体13aを有している。
ヘッド機構部64は、レーザ操作部を含む。レーザ走査部は、レーザ光を走査するものである。レーザ走査部は、例えば一対のガルバノミラーと、一対のガルバノミラーを駆動させるアクチュエータを有している。ヘッド駆動回路63は、レーザ走査部を駆動するための回路である。ヘッド制御部61は、アクチュエータを制御する。ヘッド制御部61により、レーザ走査部のアクチュエータを介して一対のガルバノミラーの駆動が制御され、加工対象物Wの加工面上において2方向(2次元方向)にレーザ光を走査する。
図1、図3に示すように、コントローラユニット11は、略直方体状の筐体11aを有している。
システム電源回路24は、メイン制御部21にシステム駆動電圧PSを供給するものである。システム電源回路24は、キースイッチ27のオンオフにより、システム駆動電圧PSの供給と停止を行う。システム駆動電圧PSは、メイン制御部21に供給される。また、システム駆動電圧PSは、第2電源ケーブルSP2により光源ユニット12の光源制御部41に供給される。さらに、システム駆動電圧PSは、第1電源ケーブルSP1により、光源ユニット12からヘッドユニット13のヘッド制御部61に供給される。したがって、各ユニット11,12,13の制御部21,41,61は、キースイッチ27のオン操作により供給されるシステム駆動電圧PSにより動作する。
光源ユニット12は、複数種類の光源ユニット12の中から選択されたものである。光源ユニット12は、加工対象物Wの多様性、等に対応するように、複数種類用意される。複数種類の光源ユニット12は、例えば出射するレーザ光の出力レベルが互いに異なる。そして、複数種類の光源ユニット12は、出力レベルに応じて、駆動電圧、駆動電力が互いに異なる。つまり、複数種類の光源ユニット12は、搭載されるレーザ光源44および光源駆動回路43の組み合わせが異なる。
図4には、光源ユニット12A、12B,12Cに対応する光源電源回路25A、25B,25Cを搭載したコントローラユニット11A、11B,11Cを示す。各コントローラユニット11A、11B,11Cの記憶部22(図2参照)には、それぞれに搭載した光源電源回路25A、25B,25Cが対応する光源ユニット12A、12B,12Cの識別情報と、光源電源回路25A、25B,25Cの出力情報とが関連づけられて記憶される。一例では、コントローラユニット11の記憶部22には、該コントローラユニット11に搭載された光源電源回路25が対応する1つ又は複数の光源ユニット12の識別情報と、光源電源回路25の出力情報とが関連づけられて記憶され得る。光源電源回路25A、25B,25Cの出力情報は、光源電源回路25A、25B,25Cが出力する光源駆動電圧PLの駆動電圧情報(電圧、電力)である。
図4に示すコントローラユニット11A,11B,11Cは、ヘッドユニット13Aに対応する光源駆動回路43Aを搭載した状態を示している。コントローラユニット11A,11B,11Cの記憶部22(図2参照)には、それぞれに搭載したヘッド電源回路26Aが対応するヘッドユニット13Aの識別情報と、ヘッド電源回路26Aの出力情報とが関連づけられて記憶される。一例では、コントローラユニット11の記憶部22には、該コントローラユニット11に搭載されたヘッド電源回路26が対応する1つ又は複数のヘッドユニット13の識別情報と、ヘッド電源回路26の出力情報とが関連づけられて記憶され得る。
システム駆動電圧PSが供給されたメイン制御部21は、電源投入による初期処理を実行した後、メイン処理を実行する。
キースイッチ27がオンされる(ステップ101)と、システム電源回路24がオン(ON)する(ステップ102)。オンしたシステム電源回路24は、システム駆動電圧PSを出力する。図2に示すように、システム駆動電圧PSは、コントローラユニット11のメイン制御部21に供給される。メイン制御部21は、システム駆動電圧PSの供給により起動する(ステップ103)。
起動したメイン制御部21は、機種情報要求を行う(ステップ104)。メイン制御部21は、要求信号を出力する。その要求信号は、図2に示す第2信号ケーブルSL2により光源制御部41に伝達される。
メイン制御部21は、電源種別情報を取得する(ステップ106)。詳しくは、メイン制御部21は、光源制御部41からの要求信号を受信し、要求信号に含まれる識別情報を取り出す。メイン制御部21は、識別情報に含まれる光源ユニット12の機種情報と、記憶部22に記憶された識別情報(機種情報)とを比較する。一例では、メイン制御部21は、要求信号の識別情報に含まれる光源ユニット12の機種情報と、記憶部22に記憶された1つ又は複数の光源ユニット12の識別情報(機種情報)とを比較し得る。そして、メイン制御部21は、要求情報の機種情報と一致する記憶部22の機種情報に関連づけられた駆動電圧情報を取得する。
図7に示すフローチャートに対して、光源ユニット12について判定する処理について説明した。ヘッドユニット13について判定する処理は、上記の光源ユニット12について判定する処理と同じである。メイン制御部21は、光源ユニット12に対する処理と同様に、ヘッドユニット13に対して処理を行うことにより、ヘッドユニット13を駆動可能か否かを判定することができる。
次に、上記のレーザ加工装置10の作用を説明する。
メイン制御部21は、加工開始操作が行われると、例えば設定用端末90において設定された加工データを制御データに変換し出力する。光源制御部41が制御データに基づいて光源駆動回路43を制御することにより、光源駆動回路43により駆動されるレーザ光源44がレーザ光を出射する。ヘッド制御部61が制御データに基づいてヘッド駆動回路63を制御することにより、ヘッド駆動回路63により駆動されるヘッド機構部64によって走査されたレーザ光が加工対象物Wに照射される。これにより、レーザ加工装置10は、照射するレーザ光により加工対象物Wを加工する。
以上説明したように、レーザ加工装置10は、以下の効果を奏する。
(1)レーザ加工装置10は、コントローラユニット11と光源ユニット12とヘッドユニット13とを第1電気ケーブル81、第2電気ケーブル82、光ファイバケーブルFLにて接続して構成される。光源ユニット12は、レーザ光を出射するレーザ光源44と、レーザ光源44を駆動する光源駆動回路43と、光源制御部41とを含む。光源制御部41は、要求信号に応答して応答信号を送信するように構成されている。コントローラユニット11は、光源駆動回路43に光源駆動電圧PLを供給する光源電源回路25を含む。コントローラユニット11のメイン制御部21は、要求信号を送信し、受信した応答信号に基づいて、光源ユニット12を駆動可能か否かを判定し、光源ユニット12が駆動可能であると判定した場合には光源電源回路25から光源駆動回路43に光源駆動電圧PLを供給する。一方、メイン制御部21は、光源ユニット12が駆動可能ではないと判定した場合には光源電源回路25から光源駆動回路43へ光源駆動電圧PLを供給しない。
実施の形態に関する説明は、本開示に関するレーザ加工装置が取り得る形態の例示であり、その形態を制限することを意図していない。本開示は実施の形態以外に例えば以下に示される実施の形態の変更例、および、相互に矛盾しない少なくとも2つの変更例が組み合わせられた形態を取り得る。
・上記実施形態では、コントローラユニット11の接続部33に対して有線接続にて設定用端末90が接続される構成であったが、これに限らない。設定用端末90をWi-Fi、Bluetooth(登録商標)、NFC(Near Field Communication)、赤外線通信などの無線通信方式により、外部装置と通信可能に構成してもよい。そして、光源ユニット12、ヘッドユニット13、コントローラユニット11のいずれかのユニットにおいても設定用端末90と同じ無線通信方式に対応した通信が可能に構成されるものであってもよい。これにより、設定自体はケーブル91による接続が不要となるため、ケーブル91の配索や着脱作業が不要となり、ユーザの利便性向上に寄与できる。さらに、ヘッドユニット13を無線通信方式による通信可能な構成とすることができる。これにより、設定後の再設定作業を含む設定作業やメンテナンス等において、ヘッドユニット13が設置される加工場所において設定の確認や変更を行うことができるため、作業性向上に寄与できる。
・上記実施形態では、電源部23を冷却するためのファン28と、レーザ光源44を冷却するためのファン45とを備える構成としたが、ファン以外の冷却手段によって冷却する構成を採用してもよい。また、ファン28,45を含めた冷却手段を省略した構成を採用してもよい。
