図1から図6に本発明の一実施形態に係る電子部品取付装置100の全体又は一部を示す。電子部品取付装置100は、所定箇所に載置された複数の電子部品を異なる間隔で被着物に取り付ける電子部品取付装置である。電子部品取付装置100は、複数列かつ複数行に整列された状態で多数の電子部品Cが密接して配置された状態において、電子部品を取り出し、その電子部品(ここではICチップC)を被着物(本実施形態においてはRFIDタグA)に取り付ける装置である。ここで、「行」と「列」は、それぞれ図1におけるX方向への配列とY方向への配列を意味する。以下、電子部品の一例としてICチップを例にとり説明する。ICチップCは、例えば多数の回路パターンが形成された薄板円盤状の半導体ウエハWが格子状に切断されて形成されている。電子部品取付装置100は、隙間なく複数列かつ複数行に整列された多数のICチップCから複数のICチップCを列状で取り出し、それらのICチップCのそれぞれをRFIDタグAに取り付ける装置である。なお、各図は模式的図面であり、各部材のサイズ、個数等を模式的に示すものである。
当該電子部品取付装置100は、半導体ウエハWが載置される載置台1と、被着物であるRFIDタグAのシートを搬送するシート搬送機構2と、載置台1からシート搬送機構2まで電子部品であるICチップCを搬送する部品搬送機構3と、部品搬送機構3によって搬送されたICチップCをRFIDタグAに取り付け移送する取付移送機構80とを有している。また、電子部品取付装置100は、各部材の動作を制御する制御部100Aを有している。
載置台1は、上述のように半導体ウエハWがレーザー等で切断され、隙間なく複数列かつ複数行に整列されたICチップCに個片化された状態で載置される。また、載置台1は、載置されたICチップCの整列方向を調整する調整手段を有している。具体的には、載置台1は、載置された半導体ウエハWを撮像する撮像部(図示省略)と、電子部品Cの整列方向が正しくない場合(図1のXY方向に合致していない場合)に、載置台1の中心を通り図1の紙面に直交する方向に伸びる回転軸を中心として半導体ウエハWを回転する回転部(図示省略)とを有している。
部品搬送機構3は、複数のICチップCをピックアップして取り出す取り出し機構としての吸着保持装置33と、吸着保持装置33が取り出したICチップCを搬送し、RFIDタグAに到達する前に隣り合うICチップCの間隔が上記異なる間隔(複数のICチップCがRFIDタグAへ取り付けられる間隔)となるよう各ICチップCを移動させ、ICチップCをRFIDタグAまで搬送する部品搬送機構3とを備えている。具体的には、部品搬送機構3は、載置台1及びシート搬送機構2の間でICチップCが仮置きされる整列部としての載置テーブル10と、載置台1から載置テーブル10までICチップCを移送する第一移送機構30と、載置テーブル10からRFIDタグAまでICチップCを移送する第二移送機構50とを有する。部品搬送機構3は、載置台1上のICチップCを、まず載置テーブル10まで第一移送機構30によって移動させて載置テーブル10に仮置きし、この載置テーブル10上のICチップCを第二移送機構50によってRFIDタグAのアンテナまで搬送する。本実施形態においては、第一移送機構30は第一方向(図1のX方向)にICチップCを移送し、第二移送機構50は第一方向に直交する第二方向(図1のY方向)にICチップCを移送する。
載置テーブル10は、上述のように第一移送機構30からICチップCを受け取り、第二移送機構50によってICチップCが受け取られる。この載置テーブル10は、第二移送機構50に接近及び離反するようスライド移動する。つまり、載置テーブル10は、第二移送機構50から離反して第一移送機構30とICチップCを受け渡す第一受渡位置P1と、第二移送機構50に接近して第二移送機構50とICチップCを受け渡す第二受渡位置P2とを移動する。なお、載置テーブル10は、第一受渡位置P1と第二受渡位置P2との間に配された図示省略のレールにスライド可能に支持されている。
第一移送機構30は、1列に並んだ8個のICチップCを同時に載置台1から取り出し、載置テーブル10に移動する。第一移送機構30は、水平方向(図1及び図2のX方向及びY方向)並びに上下方向(図1の紙面に直交する方向)に移動可能な吸着保持装置33を有している(図2参照)。また、第一移送機構30は、図2に示すように、柱部30aと、走行体31と、上下動体32とを有している。柱部30aは、第一移送機構30の移送方向に沿ってレールが配される。走行体31は、柱部30aに沿って走行する。上下動体32は、走行体31に上下動可能に支持されると共に吸着保持装置33を第一移送機構30の搬送方向に対する垂直方向(図1及び図2のY方向)に移動可能に支持する。
吸着保持装置33は、上述のように載置台1から1列に並んだ複数個のICチップCを吸着保持することができる。吸着保持装置33は、吸着するICチップCの個数を変更可能である。この吸着保持装置33は、図3~図6に示すように、脱気口36(図4参照)が形成された吸引具34と、この吸引具34に対して相対的に変位(回転)する変位体42とを備えている。脱気口36に連通することで吸着口38(図4及び図5参照)は吸引力を発揮する。変位体42は、吸引具34との相対位置によって複数の吸着口38と脱気口36との連通状態を選択的に変更可能に設けられている。
第二移送機構50は、図2に示すように、取出機構60と、仮置部70とを有する。図1及び図2を参照して、取付機構60は、整列部10から同一行6個のICチップCを同時に吸着して取り出す。仮置部70は、同一行6個のICチップCが受け渡される。つまり、第二移送機構50は、整列部10上から同一行6個のICチップCを取出手段60によって取り出して、この取り出されたICチップCを一度仮置部70に仮置きし、そして、この仮置部70上のICチップCを、アンテナシートSまで搬送するものである。
取付移送機構80は、RFIDタグA上を上下動可能な保有部81と、この保有部81を上下動可能に支持する移動部材82とを有している。取付移送機構80は、部品搬送機構3によってRFIDタグAが形成されたアンテナシートSまで搬送されたICチップCをRFIDタグAの所定位置に取り付ける。この移動部材82は、レール51に沿って水平方向(図1及び図2のY方向)に移動可能に支持されている。取付移送機構80は、実装位置P4においてICチップCをRFIDタグAに取り付ける。
図1を参照して、シート搬送機構2は、上述のようにICチップCを取り付けるRFIDタグAが形成されたアンテナシートSを搬送する機構である。本実施形態においては、シート搬送機構2は、多数のRFIDタグAが形成されたアンテナシートSを搬送している。シート搬送機構2は、取付移送機構80が吸着保持する複数のICチップCの整列方向(整列部10における行形成方向(図1のX方向))に沿ってアンテナシートSを搬送する。
電子部品取付装置100は、ICチップCを取り付けられる前においてアンテナシートS(複数のRFIDタグA)の位置を確認する被着物位置確認部材100Bを備える。被着物位置確認部材100Bは、カメラから構成されている。被着物位置確認部材100Bは、シート搬送機構2によって搬送されるアンテナシートSを実装位置P4よりも上流側で撮像する。被着物位置確認部材100Bは、制御部100Aに接続され、電子部品取付装置100は、被着物位置確認部材100Bにより確認されたRFIDタグAの位置に基づいてRFIDタグA同士の間隔を算出し、この算出した間隔に基づいてICチップCを取り付けることができる。
次に、本発明の一実施形態に係る電子装置の製造方法について説明する。この電子装置の製造方法は、上記構成からなる電子部品取付装置100を用い、ICチップCを取り付ける。
第一搬送工程では、載置台1から8個のICチップCが同時に吸着され、吸着されたICチップCが載置テーブル10に移送され、載置テーブル10に受け渡される。この第一搬送工程が繰り返し行われることで、載置テーブル10には列間が上記異なる間隔D1,D2を有する状態で複数のICチップCの列が並べられる。
第二搬送工程は、整列部10から1行複数個(本実施形態では6個)のICチップCを取出機構60が取出す工程と、この取出機構60が取り出したICチップCを反転機構90が反転する工程と、反転機構90が反転したICチップCを仮置部70に載置する工程と、仮置部70に載置された1行8個のICチップCを受取搬送機構75及び取付移送機構80がRFIDタグAまで移送しRFIDタグAに載置する工程とを有する。
電子部品取付装置100にあっては、第一移送機構30は、載置台1から複数個(本実施形態では8個)のICチップCを同時に吸着することで取り出し、第二移送機構50は、載置テーブル10から、列間に間隔を有する状態の同一行複数個(本実施形態では6個)のICチップCを同時に吸着することで取り出し、この同一行6個のICチップCをRFIDタグAに同時に載置する。このように電子部品取付装置100は、複数のICチップCを同時にRFIDタグAに載置することができるため、ICチップCの取付を効率的に行うことができる。
本発明は上記実施形態の構成に限定されるものではなく、本発明の意図する範囲内において適宜設計変更可能である。
