Abstract

Eine Vorrichtung zum gas- und flüssigkeitsdichten Versiegeln der Gehäuse von galvanischen Elementen, die die Form einer dünnen Flachzelle besitzen, durch Ultraschallverschweißung von Kunststoffschichten der Gehäusebauteile, enthält einen Amboss (1), der als Auflage der zu verbindenden Teile dient, dem eine zur Ultraschallverschweißung dienende Sonotrode (2) gegenübersteht, wobei die Oberfläche von Sonotrode (2) oder Amboss (1) im Siegelungsbereich mit einer Erhöhung (7) umgeben von einer ebenen Fläche (8) versehen ist.

Description

  • Gegenstand der Erfindung ist eine Vorrichtung zum gas- und flüssigkeitsdichten Versiegeln der Gehäuse von galvanischen Elementen, die die Form einer dünnen Flachzelle besitzen, durch Ultraschallverschweißung von Kunststoffschichten der Gehäusebauteile.
  • Galvanische Elemente in Form von dünnen und flachen Zellen sind bekannt und beispielweise dem Dokument EP 862 227 A1 zu entnehmen. Bei derartigen Zellen sind positive und negative Elektrode unter Zwischenlage von Separatoren, beispielsweise zwischen zwei als Gehäusebauteile dienenden Kunststofffolien, angeordnet, die gas- und flüssigkeitsdicht miteinander verbunden werden. Die die Gehäusebauteile bildenden Folien können auch metallisierte Kunststofffolien sein oder Metallfolien, beispielsweise Kupferfolien, die an den zum Inneren der Zelle weisenden Randbereichen mit einem Kunststoffmaterial beschichtet sind, welches nach dem Zusammenbau verschweißt wird.
  • Zur Verbindung dieser Gehäusebauteile dient oft ein Schweißverfahren, bei dem die Bauteile auf einem zu einer Sonotrode ausgerichteten Amboss fixiert werden und dann mittels Ultraschall miteinander verschweißt werden.
  • Aufgabe der Erfindung ist es, diese Ultraschallverschweißung auch bei sehr dünnen galvanischen Elementen zuverlässig zu gewährleisten.
  • Diese Aufgabe wird erfindungsgemäß bei der eingangs genannten Vorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.
  • Im Folgenden ist der Gegenstand der Erfindung anhand der Figuren näher dargestellt.
  • Fig. 1 zeigt einen Querschnitt durch eine Vorrichtung mit einer herkömmlichen Sonotrode. Fig. 2 zeigt eine Vorrichtung mit der erfindungsgemäßen Sonotrode.
  • Die zur Verschweißung von Kunststofffolien verwendeten herkömmlichen Vorrichtungen bestehen aus einem Amboss 1, und einer gegenüberliegenden Sonotrode 2. Das zu verschweißende Objekt besteht aus einer unteren Siegelfolie 3 und einer oberen Siegelfolie 4. Während des Schweißprozesses wird die gerundete Sonotrode 2 auf die obere Folie 4 gedrückt, die unter gleichzeitigem Einwirken von Ultraschall mit der unteren Folie 3 verschweißt wird. Der Energieherd, der die Folienmaterialien schmilzt ist mit 9 bezeichnet. Dabei entsteht ein Fluss von geschmolzenem Material 5 von der Sonotrode weg. Dieser Fluss wirft durch Staubildung eine Wulst 6 auf. Diese Wulst verändert die äußere Kontur der Folie, indem sich eine Erhöhung ausbildet. Für manche Anwendungen ist diese Wulst unerwünscht.
  • Erfindungsgemäß ist die in Fig. 2 dargestellte Sonotrode 2 mit einer zentrischen erhabenen Kontur 7 versehen, die umgeben von einer ebenen Kontur 8 ist. Diese Erhöhung wirkt als Energieweiser, so dass die Energie des Ultraschalls gezielt nur an der umlaufenden Linie wirkt. Der dadurch entstehende Energieherd 9 schmilzt die Folienmaterialien 3, 4 tief auf und bewirkt ein Verdrängen der Schmelze 5. Mit der Verdrängung der Schmelze wird gleichzeitig auf der Oberfläche der Siegelfolien befindlicher Schmutz bzw. Elektrolyt verdrängt. Die verdrängte Schmelze 5 bildet beidseitig neben dem Energieherd 9 Dichtkeile aus, so dass keine verschmutzte Oberfläche als Trennschicht bestehen bleibt, da der Schmutz mit der Schmelze durchgemischt wird. Die ebenen Seitenflächen 8 neben der runden Erhöhung 7 der Sonotrode 2 ebnen den Dichtkeil ein damit kein überstehender Wulst entsteht. Es ist auch möglich, die aus Erhöhung 7 und ebener Fläche 8 bestehende Kontur auf dem Amboss 1 anzubringen und eine ebene Sonotrode 2 vorzusehen.
  • Da die Siegelung am Energieherd sehr tief und fest ist, wird ein maximales Siegelresultat gewährleistet, wobei keine erhöhte Wulst entsteht.
  • Die erfindungsgemäße Vorrichtung ermöglicht das präzise Verschweißen von sehr dünnen Teilen, wie zum Beispiel das Versiegeln von Lithium-Flachzellen, die für elektronische Chipkarten vorgesehen sind und beispielsweise nur eine Dicke von 0,4 mm besitzen.
