[1.貼替え装置]
[1-1.構成]
本実施形態の貼替え装置1の処理の概要を説明する。なお、図1は、本実施形態の貼替え装置1の全体構成を示す平面模式図(a)と、側面模式図(b)であり、図3は、貼替え装置1におけるトレイ反転機構5の構成要素の部分拡大図である。
貼替え装置1は、供給トレイを供給するための構成として、供給トレイKを多段に収納するマガジン2と、マガジン2を上下移動させるエレベータ3と、マガジン2からデバイスの搭載された供給トレイKを排出し、空の供給トレイKを戻すプッシャー機構4と、マガジン2から排出された供給トレイKを受け取るトレイ反転機構5と、を備える。また、トレイ反転機構5により反転し後述する第2のシートにデバイスを貼り付けた後の第1のシートS1の表面をクリーニングするクリーニング機構6を備える。
貼替え装置1は、供給トレイKを反転させ貼り替えるための構成として、マガジン2から供給トレイKを受け取って180度反転させるトレイ反転機構5と、供給トレイKの第1のシートS1に貼付されたデバイスを貼り替えるための第2のシートS2を供給するシートロール71と、このシートロールに巻回された第2のシートS2を送り出す送りローラ72と、第2のシートS2をシートロール71から送り出す際にこの第2のシートの粘着面に貼付された保護シートを巻き取る保護シートローラ8と、を備える。
貼替え装置1は、シートを切り離し収納するための構成として、デバイスの再貼付された第2のシートS2を、所定の間隔、すなわち、ここでは収納棚13の奥行き方向の長さである20cmでカットするシートカッター11と、このシートカッター11により、切り出されたシートを保持し、上下方向に移動させるシート分類エレベータ12と、シート分類エレベータ12の下流側に設けられ、切り出された第2のシートS2を収納するトレイを多段に備えた収納棚13とを備える。
次に、上記のような構成からなる本実施形態の貼替え装置1の作用について、図1~図5を参照して、(1)トレイを供給するための処理、(2)トレイを反転させ貼り替えるための処理、(3)シートを切り離し収納するための処理の3つの局面に分けて説明する。
貼替え装置1は、トレイを供給するため、まず、マガジン2が、エレベータ3により垂直方向に移動し、所望の供給トレイKが、マガジン2からの排出位置である、プッシャー機構4又はトレイ反転機構5の吸着ハンド51の搭載面511と同一平面上に位置して停止する。
貼替え装置1は、トレイを反転させ貼り替えるための処理として、まず、供給トレイKを吸着ハンド51により吸着したトレイ反転機構5において、反転処理を行なう前に、トレイ反転機構5の供給トレイKの受け取り位置の直上に設けられた表面検査カメラ141により、供給トレイKに搭載された第1のシートS1上に貼付したデバイス表面の外観検査を行う。
上記のような送りローラ72の回転駆動により、第2のシートS2に貼付されたデバイスが下流側に搬送され、シート分類エレベータ12の保持ローラ121と122との間まで搬送されてくる。このとき、下流側の収納棚13に近接する保持ローラ122において、第2のシートS2の到達が、センサやカメラ等の検知手段によって確認されると、送りローラ72は搬送を停止する。
以上のような本実施形態の貼替え装置1によれば、分類分けされたデバイスが貼付された第1のシートを備えたトレイを多段に収納するマガジンから、後工程で利用可能なサイズの第2のシートへデバイスの貼替えを順次実行することで、オートメーションによるデバイスのシート間での貼替えを実現し、処理の高速化と利便性の向上を図ることができる。また、人手によるデバイスの貼替え等に比較し、ロッド混入などのミスを防ぐことができる。
本発明の分類貼替え方法を実行に当たっては、上記貼替え装置における貼替え処理の前提として、分類装置100によるデバイスの分類処理が行なわれ、この分類処理により、上述のマガジン2に対して、分類ごとにデバイスが分けてトレイに搭載される必要がある。そこで、以下では、本発明の分類貼替え方法を実施するための一処理を担う装置として、分類装置100について説明する。
本実施形態の分類装置100は、前工程において行なわれるデバイスの特性検査とそれに基づく分類処理の一部を担うものであって、本装置の構成を説明する前提として、まず特性検査並びに分類処理の概要を説明する。
[2-2-1.分類装置の全体構成]
分類装置100は、図6に示すように回転軸Oを中心としてθ回転するドラム101を備える。このドラム101は、モータM1(図6(c)参照)により回転力を付与され回転軸Oを中心として回転するとともに、回転軸O上を図中ドラム101の下部に設けられた移送機構により、ドラムの軸方向(図中Y軸方向)と、このドラムの軸方向と垂直方向(図中X軸方向)に向かってスライド移動するためのドラム移動機構104を備える。
デバイスの受渡し装置110は、図6(b)に示すように、デバイスを吸着保持するとともに、上下動して(図中、Z軸方向)、間欠的に真空吸着・真空破壊を繰り返すことで、デバイスの受け取りと受渡しを行なうピックアップノズル111と、このピックアップノズル111を支持板112により固定されたモータM2により180度回転させて、ターンテーブル側の受け取り位置と、ドラム101側の受渡し貼付け位置とを移動させる回転アーム113とを備える。
本実施形態の分類装置100において、トレイ102の交換は、図6に示すように、上述したデバイスの貼付け位置からドラム101が90度回転した位置に設けたトレイ交換装置120により行なう。なお、図8においては、便宜上、トレイ交換装置120の構成要素のうち、トレイ交換用アーム121のみを示しているが、実際には、このトレイ交換用アーム121のY軸方向で挟むように、図8に示すような収納マガジン126b及び供給マガジン126a、トレイ仮置きステージ127、プッシャー機構128並びにエレベータ129a,129bが設けられている。
[2-3-1.ターンテーブル上の移送処理]
前工程において、デバイスの組み立てを終え、ウエハリングに張られたウエハシートに貼付されたデバイスは、ダイシングにより個片化され、これをターンテーブルTに設けた吸着ノズルによりピックアップされる。
デバイスが、ピックアップノズル111の受け取り位置まで移動すると、ピックアップノズル111は、Z軸移動機構114の作用により、ターンテーブルT上の載置台Pである受け取り位置まで下降し、真空吸着により、載置台Pからデバイスをピックアップする。
続いてピックアップノズル111は、支持板112により固定されたモータM2の駆動により、回転アーム113が180度回転するのに伴って、ターンテーブルT上の載置台P上の受け取り位置から、ドラム101側に向かい、トレイ102への受渡し貼付け位置へ移動する。
上記のような処理を繰り返し、一つの分類のトレイ102上にデバイスが満杯になると、それが画像により認識され、当該トレイ102の位置情報ないしはID情報が、ドラム移動機構104及びトレイ交換装置120に入力される。
以上のような本実施形態の分類装置100によれば、ドラム101に保持された分類ごと各トレイ102はそれぞれ独立しているので、分類ごとに個別に貼付及び交換ができ、例えば、一つの分類が満杯になることで他の分類へも影響を及ぼすような無駄がなくなり、生産性の向上を図ることができる。
[1.貼替え装置]
本発明は、上記実施形態に示した構成に限られるものではなく、例えば次のような実施態様も包含するものである。すなわち、上記実施形態におけるマガジン2と、エレベータ3及びプッシャー機構4の配置は、装置構成上の一例を示すものに過ぎず、マガジン2からの供給トレイKの排出及び吸着ハンド51への受渡しと、供給トレイKの吸着ハンド51からマガジン2への返却を、プッシャー機構4が行なうことができるような構成であれば良い。具体的には、上記実施形態では、吸着ハンド51、マガジン2及びプッシャー機構4の2片のプッシャーを、第2のシートS2の幅方向(図中Y軸方向)に並べたが、本発明では、これに限らず、第2のシートS2の送り方向(図中X軸方向)に並べて構成することも可能である。
上記実施形態では、ドラム101の回転軸Oを、水平方向の配置としたが、本発明では、このような態様に限られず、図9に示すように、回転軸Oを垂直方向にして設置することも可能である。この場合には、上記実施形態におけるピックアップノズル111は、ターンテーブルTからデバイスをピックアップした後、90度回転して、ドラム101への受渡し貼付け処理を行なうこととなる。なお、その他の各装置の詳細な構成並びに作用は、上記実施形態と同様に構成することで、上記実施形態と同様の効果を得ることが可能である。
