Abstract
Description
部品供給装置の供給ヘッドと干渉(衝突)することを避ける必要がある。このため、実装ヘッドと供給ヘッドとを同時に動作させるとヘッド同士が干渉する場合は、一方のヘッドの動作を、他方のヘッドの動作が完了するまで停止させてヘッド同士の干渉を防ぐように制御する必要があり、その結果、生産能率が低下する。
図1及び図2に示すように、部品実装機11には、ウエハ部品供給装置12が着脱可能にセットされる。部品実装機11には、ウエハ部品供給装置12のセット位置に隣接してフィーダセット台13が設けられ、このフィーダセット台13上にテープフィーダ等のフィーダ(図示せず)が着脱可能にセットされる。フィーダセット台13上にセットするフィーダは、テープフィーダに限定されず、バルクフィーダ、スティックフィーダ等であっても良く、これらのフィーダの中から複数種のフィーダをフィーダセット台13上にセットしても良い。
実装動作の完了までにウエハ部品22の画像処理・吸着・反転動作が完了していなければ、ウエハ部品22の画像処理・吸着・反転動作の完了後に直ちにウエハ部品22の実装動作を開始することができる。これにより、ウエハ部品22の実装動作開始待ち時間を減らすことができて、生産能率を向上できる。
ダ部品の吸着・実装動作とオーバーラップして行われるように部品実装順序を設定するようにしても良い。
