Abstract
Description
1.表面実装機の全体構成
表面実装機1は、図1に示すように、基台11と、プリント基板Pを搬送する搬送コンベア20と、ヘッドユニット60と、ヘッドユニット60を基台11上にて平面方向(XY方向)に移動させる駆動装置30とを備えている。尚、以下の説明において、基台11の長手方向(図1の左右方向)をX方向と呼ぶものとし、基台11の奥行方向(図1の上下方向)をY方向、図2の上下方向をZ方向とする。
部品供給テープ70は、図3に示すように、キャリアテープ71と、これに貼着されるカバーテープ75とから構成されている。キャリアテープ71の材質は、例えば、合成樹脂製であり、カバーテープ75の材質は、例えば、合成樹脂製である。キャリアテープ71は、上方に開口した空洞状の部品収納部72を一定間隔置きに有しており、各部品収納部72にはチップ抵抗等の小型電子部品Wが収納されている。
図10に示すように、切開刃161は刃先163を上流側に向けつつ上方を向いている。そして、キャリアテープ71とカバーテープ75の間に刃先163が挿入された状態で、切開刃161を通過するよう部品供給テープ70が送られることで、切開刃161がカバーテープ75を切開する。
(A)テープ未挿入時
図14はフィーダ上部の正面図である。図15は一部を断面で示したフィーダ上部の正面図であり、部品供給テープ70がフィーダ80に挿入される前の状態を示している。
部品供給テープ70が未装着である未装着フィーダ80に対して部品供給テープ70を装着するため、部品供給テープ70をフィーダ後部からテープ通路83に挿入して、自動ローデング装置100を作動させると、部品供給テープ70は第3スプロケット101の回転に伴い、テープ通路83の下流側へと搬送されてゆく。
本実施形態の表面実装機1によれば、ローデング動作時は、押さえ面155Cから刃先163を突出させることで、両テープ間に刃先が挿入され易くなる。また、通常使用時は、押さえ面174から刃先163を突出させないようにすることで、切開刃161の刃先163がキャリアテープ71の部品収納部72に収容された電子部品Wと接触することを抑制できる。
実施形態1では、切開刃161の突出量を回転部材171で調整する構成を示した。実施形態2は、切開刃161の突出量を調整する構造が実施形態1と相違している。
実施形態2では、刃カバー320を上下移動することで、切開刃310の突出量を調整する構成を例示した。
実施形態3では、切開刃410を上下移動させるのに、ピニオンギヤ430とラックギヤ440を利用した例を示した。
