Eine erfindungsgemäße galvanische Flachzelle umfasst einen zwischen zwei einander im Wesentlichen parallel gegenüber liegenden Hüllblechen angeordneten, umlaufenden Rahmen mit einer verschließbaren Elektrolyteinfüllöffnung. Der Rahmen ist aus einem Rahmenmaterial gebildet. Die Elektrolyteinfüllöffnung ist mittels thermischen Schweißens zumindest unter Beteiligung des Rahmenmaterials im Bereich der Elektrolyteinfüllöffnung verschließbar. Unter Schweißen wird das unlösbare Verbinden von Bauteilen unter Anwendung von Wärme und/oder Druck – mit oder ohne Schweißzusatzwerkstoffe verstanden. Dabei werden die beteiligten Bauteile, in diesem Fall zumindest das Rahmenmaterial im Bereich der Elektrolyteinfüllöffnung zumindest teilweise aufgeschmolzen und aneinander grenzende, aufgeschmolzene Bereiche der beteiligten Bauteile beim Erstarren miteinander verschweißt, insbesondere ohne Schweißzusatzwerkstoffe. Das Verschweißen der Elektrolyteinfüllöffnung ist im Gegensatz zum Einsatz von Nieten auch in dem nur begrenzt mechanisch belastbaren Rahmen möglich. Im Vergleich mit Klebeverfahren verkürzt sich eine Durchlaufzeit der galvanischen Flachzelle, da keine Aushärtezeit benötigt wird sondern die Fügestelle sofort nach dem Erkalten dicht ist. Durch die genannten Vorteile ist zudem ein Abdichten der galvanischen Flachzelle mit geringeren Kosten erreichbar.A Galvanic flat cell according to the invention comprises one between two substantially parallel to each other arranged lying cladding, surrounding frame with a lockable electrolyte filling opening. The frame is formed of a frame material. The electrolyte filling opening is at least under participation by means of thermal welding of the frame material in the region of the electrolyte filling opening closable. This becomes insoluble under welding Connecting components using heat and / or pressure - with or understood without welding consumables. It will be the components involved, in this case at least the frame material in the region of the electrolyte filling opening at least partially melted and juxtaposed, molten Areas of the components involved welded together during solidification, in particular without welding consumables. Welding the Electrolyte filling opening is in contrast to the use of rivets even in the limited mechanical loadable frame possible. Compared with bonding process, a turnaround time is reduced the galvanic flat cell, since no curing time is required but the joint is tight immediately after cooling is. Due to the advantages mentioned is also a sealing of the galvanic Flat cell achievable with lower costs.
In einer Ausführungsform der Erfindung wird ein Stopfen in die Elektrolyteinfüllöffnung eingesetzt und mit dem Rahmenmaterial im Bereich der Elektrolyteinfüllöffnung verschweißt. Insbesondere ist der Stopfen aus dem Rahmenmaterial gebildet, da ein Verschweißen gleichartiger Stoffe besonders einfach ist. Vorzugsweise ist das Rahmenmaterial dabei ein Thermoplastmaterial, beispielsweise Polypropylen, da sich dieses besonders leicht thermisch verformen lässt und gute Isolatoreigenschaften aufweist. Der Stopfen wird insbesondere mittels eines beheizten Nietwerkzeugs in die Elektrolyteinfüllöffnung eingesetzt und mit dem Rahmenmaterial im Bereich der Elektrolyteinfüllöffnung verschweißt. Das Nietwerkzeug dient dabei sowohl dem Eintrag von Wärme als auch der mechanischen Verpressung des Stopfens mit dem Rahmenmaterial des Rahmens im Bereich der Elektrolyteinfüllöffnung.In an embodiment of the invention is a plug in the electrolyte filling opening inserted and with the frame material in the area of the electrolyte filling opening welded. In particular, the plug is made of the frame material formed, since a welding of similar materials especially easy. Preferably, the frame material is a thermoplastic material, For example, polypropylene, since this is particularly easy thermal deform and has good insulator properties. The plug is in particular by means of a heated riveting tool inserted into the electrolyte filling opening and with the frame material in the area of the electrolyte filling opening welded. The riveting tool serves both the entry of heat as well as the mechanical pressing of the plug with the frame material of the frame in the area of the electrolyte filling opening.
In einer weiteren Ausführungsform ist an der Elektrolyteinfüllöffnung eine Vorform aus dem Rahmenmaterial ausgebildet, die mittels Wärme und Druck zum Verschluss der Elektrolyteinfüllöffnung verformbar und verschweißbar ist. Die Vorform kann beispielsweise in der Art einer aus der Elektrolyteinfüllöffnung herausragenden Tülle gebildet sein, durch die das Elektrolyt eingefüllt wird. Zum Verschließen der Elektrolyteinfüllöffnung wird die tüllenförmige Vorform mittels des Nietwerkzeugs aufgeschmolzen und unter leichtem mechanischen Druck in die Elektrolyteinfüllöffnung gepresst, wo die Innenwandungen der Vorform schließlich miteinander verschmelzen, d. h. verschweißt werden. Vorteilhaft ist hierbei, dass die Vorform bereits am Rahmen ausgebildet ist, beispielsweise mittels Spritzguss, so dass keine zusätzlichen Bauteile erforderlich sind und im Nietwerkzeug gehalten werden müssen.In Another embodiment is at the Elektrolytinfüllöffnung a preform of the frame material formed by means of heat and pressure to close the Elektrolyteinfüllöffnung deformable and is weldable. The preform can be, for example in the manner of one out of the electrolyte fill port outstanding spout formed by the electrolyte is filled. For closing the electrolyte filling opening becomes the tulle-shaped preform by means of the riveting tool melted and under slight mechanical pressure in the Elektrolyteinfüllöffnung pressed, where the inner walls of the preform finally merge together, d. H. be welded. Advantageous here is that the preform is already formed on the frame, For example, by injection molding, so no additional Components are required and must be kept in the riveting tool.
In einer weiteren Ausführungsform weist eines der Hüllbleche im Bereich der Elektrolyteinfüllöffnung eine überstehende Lasche auf, die zum Verschließen mittels eines beheizten Biegestempels über die Elektrolyteinfüllöffnung gebogen und durch Wärmeeintrag aus dem Biegestempel mit dem Rahmenmaterial im Bereich der Elektrolyteinfüllöffnung verschweißt wird. Dabei wird das Rahmenmaterial im Bereich der Elektrolyteinfüllöffnung teilweise aufgeschmolzen und beim Erstarren mit der darin eingebetteten Lasche verschweißt. Diese Ausführungsform kommt ebenfalls ohne zusätzliche Bauteile aus.In Another embodiment has one of the cladding sheets in the area of the electrolyte filling opening a protruding Lug on, which can be closed by means of a heated Bend punch over the electrolyte filling opening bent and by heat input from the punch with welded to the frame material in the field of Elektrolyteinfüllöffnung becomes. The frame material is in the area of the electrolyte filling opening partially melted and solidified with the embedded therein Lash welded. This embodiment comes also without additional components.
Die überstehende Lasche ist vorzugsweise chemisch und/oder mechanisch vorbehandelt, um das Anhaften des Rahmenmaterials zu verbessern. Mit einer chemischen Vorbehandlung werden beispielsweise Fremdstoffe aus der Oberfläche der metallischen Lasche entfernt. Bei einer mechanischen Vorbehandlung wird die Oberfläche der Lasche beispielsweise aufgeraut. Beide Maßnahmen ermöglichen eine verbesserte Durchdringung der Oberfläche der Lasche mit dem Rahmenmaterial und so eine haltbarere Verbindung.The supernumerary Tab is preferably chemically and / or mechanically pretreated, to improve the adhesion of the frame material. With a chemical Pre-treatment, for example, foreign substances from the surface the metallic tab removed. In a mechanical pretreatment For example, the surface of the tab is roughened. Both measures allow for improved penetration the surface of the flap with the frame material and so on a more durable connection.
