Description
ここで紹介する発明品は、プラスチック部品溶接用の超音波溶接装置です。本装置は、溶接作業を実施するために溶接部分まで本装置を動かすハンドラー、アクチュエーターまたはロボットアームへの取り付けに適したソノトロード、ブースターおよびコンバーターで構成されており、これには固定ヘッドおよび冷却ヘッドが取り付けられています。
〔本発明品の用途分野〕
本発明品は、超音波によるプラスチックの溶接に適しています。
〔最新式〕
自動車産業などのいくつかの分野では、プラスチックを溶接するために、超音波が一般的に使用されています。接合部にはボアが一式あり、スタッドがボアを通る2つ目の部品に使用されます。両部品を重ね合わせてから、溶接します。溶接作業中は、中が空洞のプラスチックスタッドに対してソノトロードが軸方向に動き、これによりプラスチックが溶けて、圧縮され、スタッドヘッドが形成されたり、どちらかの部品が外れないように、1つ目の部品に固定されます。
これは、特に溶接される部品間に例えばライニングなどの材料がある場合、溶接部で2つの部品が十分に固定されていなかった場合、部品が不安定となり、不必要な隙間や溝ができる原因となります。またこのような溶接は、メーカー側で受け付けられない場合もあります。
〔発明品の説明〕
発明品つまり、超音波溶接装置は、ハンドラーあるいはロボットアームへの取り付けに適したソノトロード、超音波コンバーターおよびブースターで構成されており、これには固定ヘッドおよび冷却ヘッドも取り付けられています。本装置の特徴として、特に、溶接部分に近接する辺縁部で溶接する部品への正面からの加圧、部品間の不要な隙間の除去、装置の外面によるソノトロードの効率的な冷却、溶接作業中に溶接部に注入する圧搾空気の回路確保などの、既知の問題を解決できることが挙げられます。
〔図の説明〕
上記の説明の補足および、発明品の特徴の理解を促すため、本仕様書に図面を添付しています。これには以下の実例および制限のない性質が記載されています。
