Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Vorrichtung zum Laminieren mehrerer Komponenten zu einem Bauteil anzugeben.The invention has for its object to provide a comparison with the prior art improved device for laminating a plurality of components to a component.
Die Aufgabe wird erfindungsgemäß mit einer Vorrichtung gelöst, welche die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved with a device having the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Vorrichtung zum Laminieren mehrerer Komponenten zu einem Bauteil umfasst zumindest eine Heizfläche, mittels welcher die Komponenten erhitzbar sind. Erfindungsgemäß sind mittels der Heizfläche die Komponenten durch Einbringen einer Laminierkraft schichtenweise flächig übereinander laminierbar, wobei die Heizfläche flexibel ausgebildet und konvex gekrümmt ist und wobei sich die gekrümmte Heizfläche bei Erzeugung der Laminierkraft und Annäherung an die Komponenten ausgehend von einem mittleren Bereich zu ihren Randbereichen hin kontinuierlich an die Komponenten anlegt und begradigt.The device for laminating a plurality of components to a component comprises at least one heating surface, by means of which the components can be heated. According to the invention, by means of the heating surface, the components can be laminarly laminated in layers by introducing a laminating force, the heating surface being flexible and convexly curved, and the curved heating surface being continuous when generating the laminating force and approaching the components starting from a middle region towards its edge regions attached to the components and straightened.
Durch die Ausbildung der Heizfläche und der während der Laminierung erfolgenden Ebenpressung der Heizfläche können eventuell zwischen den Komponenten befindliche Gaseinschlüsse, insbesondere Lufteinschlüsse, entweichen, bevor die Komponenten dauerhaft miteinander laminiert sind. Insbesondere bei der Herstellung einer Membran-Elektroden-Anordnung für eine Brennstoffzelle, bei welcher die Komponenten flächig laminiert werden, kann durch Vermeidung des Einschlusses von Gaseinschlüssen die Zerstörung von Kapselungen in der Membran-Elektroden-Anordnung vermieden werden, so dass die Zuverlässigkeit und Lebensdauer der Membran-Elektroden-Anordnung und somit der Brennstoffzelle erhöht werden.As a result of the formation of the heating surface and the eflection of the heating surface during the lamination, gas inclusions, in particular air inclusions, which may be present between the components, can escape before the components are permanently laminated together. In particular, in the production of a membrane-electrode assembly for a fuel cell in which the components are laminated surface, the destruction of encapsulants in the membrane-electrode assembly can be avoided by avoiding the inclusion of gas inclusions, so that the reliability and life of the Membrane electrode assembly and thus the fuel cell can be increased.
Weiterhin sind durch den Einsatz der erfindungsgemäßen Vorrichtung kontinuierliche Produktionsschritte realisierbar, unterschiedliche Applikationstechniken und/oder Applikationspositionen miteinander kombinierbar, die Handhabung der Komponenten und des Bauteils während der Herstellung und somit die Herstellbarkeit des Bauteils vereinfacht. Weiterhin ist eine konstant hohe Produktqualität erzielbar.Furthermore, continuous production steps can be realized by the use of the device according to the invention, different application techniques and / or application positions can be combined with each other, the handling of the components and of the component during manufacture and thus the manufacturability of the component simplified. Furthermore, a consistently high product quality can be achieved.

Während des Laminierens werden die Materialien mittels Druck und Wärme flächig miteinander verbunden, wobei nach dem Stand der Technik hergestellte Membran-Elektroden-Anordnungen bei großflächiger Laminierung mittels parallel schließenden und unflexiblen Heizplatten Lufteinschlüsse L1 bis L4 aufweisen können, da im laminierten Bereich A1 eingeschlossene Luft während des Laminierens nicht entweichen kann. Die im laminierten Bereich A1 vorhandenen Lufteinschlüsse L1 bis L4 können bei mechanischer Belastung der Membran-Elektroden-Anordnung ihre Form und Position verändern, woraus die Gefahr resultiert, dass eine durch die Laminierung entstandene Kapselung eines von dem laminierten Bereich A1 rahmenförmig umgebenden mittleren Bereichs A2 beschädigt und somit undicht wird. Der mittlere Bereich A2 bildet den aktiven Bereich der Membran-Elektroden-Anordnung, wobei eine Beschädigung der Kapselung dieses Bereichs A2 zur Zerstörung der Membran-Elektroden-Anordnung führt.During lamination, the materials are bonded together by pressure and heat, and prior art membrane-electrode assemblies may have air pockets L1 to L4 in large area lamination by means of parallel and inflexible heating plates, since air trapped in the laminated area A1 during lamination can not escape. The air pockets L1 to L4 present in the laminated area A1 can change their shape and position when the membrane-electrode arrangement is subjected to mechanical stress, which results in the risk of damage to an encapsulation caused by the lamination of a central area A2 surrounding the laminated area A1 in the manner of a frame and thus leaking. The middle region A2 forms the active region of the membrane-electrode arrangement, wherein damage to the encapsulation of this region A2 leads to the destruction of the membrane-electrode arrangement.
