Description
(測定装置1の構成)
測定装置1は、例えばフィーダ保守装置に組み込まれ、フィーダ50の移送動作の精度を測定する。本実施形態において、フィーダ50の測定装置1は、図1に示すように、基台2に設けられたフィーダ保持部3により被測定体であるフィーダ50を保持する。測定装置1に保持されたフィーダ50は、電力を供給されるとともに、後述する制御装置20と通信可能な状態となる。
フィーダ50は、図示しない部品実装機における部品供給装置のスロットにセットされる。フィーダ50は、リールに巻回された部品テープ(本発明の「移動体」に相当する)をピッチ送りして、取出し部Ntにおいて電子部品を取り出し可能に供給する。
測定装置1は、フィーダ50のピッチ送りの動作精度の測定に用いられる測定治具を備える。本実施形態において、測定治具は、図3に示すように、部品テープを模した専用の測定用テープ80である。測定用テープ80は、フィーダ50により移送された場合に変形が生じにくい金属などの材料により形成される。測定用テープ80は、テープ本体81と、複数の送り穴82と、複数の測定マーク83とを有する。
測定装置1の制御装置20は、図1に示すように、移動制御部21と、撮像制御部22と、画像処理部23と、誤差測定部24とを備える。移動制御部21は、フィーダ制御部70を介して駆動装置60に指令値を送出して、測定カメラ10に対して測定用テープ80を移送方向の指令位置に位置決めする。移動制御部21は、フィーダ制御部70に対して、例えば現在の駆動装置60の状態から規定量だけ測定用テープを移送するように指令値を送出する。
上記の測定装置1によるフィーダ50の動作精度の測定処理について説明する。なお、ここでは、フィーダ50に適正な補正量を設定するために、測定装置1が位置決め誤差を測定する態様を例示する。また、測定処理に際して、測定用テープ80が装填されたフィーダ50が測定装置1のフィーダ保持部3にセットされる。
測定装置1は、移動体(部品テープ)を規定の移送方向に移動させる駆動装置60を備える被測定体(フィーダ50)を対象として、駆動装置60の動作精度を測定する。測定装置1は、所定のカメラ視野11を有する測定カメラ10と、カメラ視野11における移送方向の幅Wfより狭い規定間隔Pで且つ移送方向に沿って配列された複数の測定マーク83を有する測定治具(測定用テープ80)と、駆動装置60に指令値を送出して、測定治具(測定用テープ80)を移送方向の指令位置に位置決めする移動制御部21と、位置決めされた測定治具(測定用テープ80)を測定カメラ10により撮像して画像データを取得する撮像制御部22と、画像データに含まれる複数の測定マーク83に基づいて、測定治具(測定用テープ80)の実位置を算出する画像処理部23と、指令位置および実位置に基づいて、駆動装置60による移送方向の位置決め誤差ΔSを測定する誤差測定部24と、を備える。
