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. The invention relates to a device for gas and liquid-tight sealing the Housing of galvanic elements, which have the shape of a thin flat cell, by Ultrasonic welding of plastic layers of the housing components.

Galvanische Elemente in Form von dünnen und flachen Zellen sind bekannt und beispielweise 1 der 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. Galvanic elements in the form of thin and flat cells are known and, for example, 1 EP 862 227 A1. In such cells there are positive and negative electrodes with the interposition of separators, for example between two as housing components Serving plastic films, arranged, the gas and liquid tight connected together become. The foils forming the housing components can also be metallized plastic foils be or metal foils, for example copper foils, facing the inside of the cell Edge areas are coated with a plastic material, which after Assembly is welded.

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. A welding process in which the components are used is often used to connect these housing components are fixed on an anvil aligned to a sonotrode and then by means of Ultrasonically welded together.

Aufgabe der Erfindung ist es, diese Ultraschallverschweißung auch bei sehr dünnen galvanischen Elementen zuverlässig zu gewährleisten. The object of the invention is this ultrasonic welding even with very thin to ensure galvanic elements reliably.

Diese Aufgabe wird erfindungsgemäß bei der eingangs genannten Vorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. In den Unteransprüchen sind vorteilhafte Ausgestaltungen der Vorrichtung angegeben. This object is achieved by the device mentioned at the outset by characterizing features of claim 1 solved. In the subclaims are advantageous Refinements of the device specified.

Im Folgenden ist der Gegenstand der Erfindung anhand der Figuren näher dargestellt. The subject matter of the invention is illustrated in more detail below with the aid of the figures.

Fig. 1 zeigt einen Querschnitt durch eine erfindungsgemäße Vorrichtung. Fig. 2 zeigt eine Draufsicht auf die Vorrichtung und Fig. 3 einen Teilschnitt durch die Vorrichtung. Fig. 1 shows a cross section through a device according to the invention. FIG. 2 shows a top view of the device and FIG. 3 shows a partial section through the device.

Die erfindungsgemäße Vorrichtung besteht im wesentlichen aus einer Trägerplatte 1, auf der eine Ambossplatte 2 zentrisch zu einer oberhalb der Ambossplatte 2 angeordneten Sonotrode 4 gelagert ist. Als Lagerung dient vorzugsweise eine Kugel 3. Die Ambossplatte 2 ist durch in ihren Randbereichen angeordnete Führungsmittel 6, beispielsweise Bundschrauben, gelagert und durch Druckfedern 5 stabilisiert. An der Ambossplatte ist ein Zentrierrahmen 7 über Senkschrauben 12, Abstandshalter 13 und Zentrierstifte 8 befestigt. Auf der Ambossplatte 2 ist eine weitere Platte 10 aus isolierendem Material, beispielsweise aus Glas oder aus keramischem Material oder auch eine Stahlplatte, angebracht. Zwischen dieser Platte 10 und der Ambossplatte 2 ist eine dünne Klebeschicht vorgesehen. Diese Klebeschicht wirkt als Entkopplung, sodass der Sitz der zentrischen Lagerung bzw. der Kugel 3 nicht durch die Ultraschalleinwirkung zerstört wird. The device according to the invention essentially consists of a carrier plate 1 on which an anvil plate 2 is mounted centrally to a sonotrode 4 arranged above the anvil plate 2 . A ball 3 preferably serves as storage. The anvil plate 2 is supported by guide means 6 , for example collar screws, arranged in its edge regions and stabilized by compression springs 5 . Of the anvil plate a centering frame 7 via countersunk screws 12, spacers 13 and centering pins 8 is fixed. A further plate 10 made of insulating material, for example made of glass or ceramic material or also a steel plate, is attached to the anvil plate 2 . A thin adhesive layer is provided between this plate 10 and the anvil plate 2 . This adhesive layer acts as a decoupling, so that the seat of the central bearing or the ball 3 is not destroyed by the action of ultrasound.

In den Zentrierrahmen 7 wird der nicht näher dargestellte Folienverbund, der das galvanische Element bildet, eingelegt und entlang der Kontur 14 verschweißt. Die Sonotrode 4 ist zentrisch gegenüber der Kugel 3 angeordnet. In the centering frame 7 , the film composite, not shown, which forms the galvanic element, is inserted and welded along the contour 14 . The sonotrode 4 is arranged centrally with respect to the ball 3 .

Die obere Ambossplatte ist in Ruhestellung durch die Druckfedern 5 frei vom Kugelsitz am Anschlag der Bundschrauben 6 gelagert. Diese Bundschrauben 6 sind so abgestimmt, dass bereits eine Grobausrichtung zur Sonotrode 4 gegeben ist. Zum Verschweißen fährt die Sonotrode 4 auf den in die Ausnahme des Zentrierrahmens 7 eingelegten Folienverbund, der die Zelle bildet und drückt die Ambossplatte 2 in den Sitz der Kugel 3. Da die Kugel 3 zentrisch zur Sonotrode 4 angeordnet ist, richtet sich die Ambossplatte 2 exakt zur Sonotrode 4 hin aus. Die Ambossplatte 2 gleicht somit Unparallelitäten im Bereich von beispielsweise 1/100 mm aus. Die mit den Führungsmitteln bzw. Bundschrauben 6 erzielte grobe Ausrichtung verhindert ein zu großes Wippen der Ambossplatte 2, sodass auf die Zellenbestandteile keine Kräfte einwirken, die diese gegeneinander verschieben könnten. The upper anvil plate is in the rest position by the compression springs 5 free from the ball seat on the stop of the collar screws 6 . These collar screws 6 are coordinated such that a rough alignment with the sonotrode 4 is already provided. For welding, the sonotrode 4 moves onto the film composite inserted in the exception of the centering frame 7 , which forms the cell, and presses the anvil plate 2 into the seat of the ball 3 . Since the ball 3 is arranged centrally to the sonotrode 4 , the anvil plate 2 aligns exactly with the sonotrode 4 . The anvil plate 2 thus compensates for non-parallelism in the range of, for example, 1/100 mm. The rough alignment achieved with the guide means or collar screws 6 prevents the anvil plate 2 from rocking too much, so that no forces act on the cell components which could move them against one another.

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. The device according to the invention enables precise welding of very thin ones Parts, such as sealing lithium flat cells, used for electronic Chip cards are provided and for example only have a thickness of 0.4 mm.
