- 一定の間隔に送り穴と部品収納用キャビティを設けた第1キャリアテープと第2キャリアテープを互いに接近する方向に送ってスプライシング位置に位置決めし、該スプライシング位置において前記第1および第2キャリアテープをスプライシングテープにより接続するスプライシング装置におけるスプライシングテープ送り装置であって、
前記スプライシング位置に、前記第1および第2キャリアテープの送り方向と直交する方向に送られる連続した保護テープに間隔を有して貼付され、前記第1および第2キャリアテープを接続する複数のスプライシングテープと、
前記保護テープを送る保護テープ送り装置と、
前記スプライシング位置の直前の位置に送られた前記スプライシングテープを検知するテープ検知センサと、
前記保護テープ送り装置を制御して、前記テープ検知センサが前記スプライシングテープを検知した位置から、後続するスプライシングテープが前記テープ検知センサによって検知されるまで前記保護テープを単位距離ずつN回送るとともに、前記後続するスプライシングテープが前記テープ検知センサによって検知された位置から前記保護テープを一定距離送って、前記スプライシングテープを前記スプライシング位置に位置決めする制御装置と、
を備えたことを特徴とするスプライシングテープ送り装置。 - 前記保護テープ送り装置は、前記保護テープの幅方向の両端に形成された送り穴に係合する係合歯を有するスプロケットと、該スプロケットを回転するサーボモータを含み、該サーボモータが前記保護テープの送り開始時に原位置に復帰される請求項1に記載のスプライシングテープ送り装置。
- 前記スプロケットの前記係合歯は、前記保護テープの送り穴に隙間なく係合する歯元部を有し、該歯元部に前記保護テープの送り穴が隙間なく係合するように、前記保護テープを押さえる押さえ部材を備えた請求項2に記載のスプライシングテープ送り装置。
- 前記単位距離および一定距離は、前記保護テープに形成された前記送り穴のピッチの整数倍である請求項1ないし請求項3のいずれか1項に記載のスプライシングテープ送り装置。
- 前記スプライシングテープには、前記スプライシング位置に設けられた位置決めピンに係合する位置決め穴が、前記保護テープを貫いて形成されている請求項1ないし請求項4のいずれか1項に記載のスプライシングテープ送り装置。
- 一定の間隔に送り穴と部品収納用キャビティを設けた第1キャリアテープと第2キャリアテープを互いに接近する方向に送ってスプライシング位置に位置決めし、該スプライシング位置において前記第1および第2キャリアテープをスプライシングテープにより接続するスプライシング装置におけるスプライシングテープ送り方法であって、
前記スプライシング位置に位置決めされた前記第1および第2キャリアテープに跨って接着されるスプライシングテープを貼付した保護テープを送って、前記スプライシングテープをテープ検知センサによって検知される前記スプライシング位置の直前の位置まで送り、
この直前の位置から後続するスプライシングテープが前記テープ検知センサによって検知されるまで前記保護テープを単位距離ずつN回送り、
しかる後、前記保護テープを一定距離送って、前記スプライシングテープを前記スプライシング位置に位置決めする、
スプライシングテープ送り方法。
