Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Verfahren zum Verbinden zweiter Bauteile, insbesondere zweier aus unterschiedlichen Materialien bestehenden Bauteile, wobei an einem der Bauteile eine Oberflächenstruktur vorgesehen ist, die von dem verflüssigten Material des anderen Bauteils beim Fügeprozess ausgefüllt wird, um die Verbindung zwischen den beiden Bauteilen herzustellen. Ferner betrifft die Erfindung einen Bauteileverbund, der nach einem erfindungsgemäßen Verfahren hergestellt ist.The invention relates to a method for connecting two components, in particular two components made of different materials, a surface structure being provided on one of the components which is filled by the liquefied material of the other component during the joining process in order to establish the connection between the two components. The invention also relates to a component assembly which is produced by a method according to the invention.
Stand der TechnikState of the art
Ein Verfahren zum Verbinden zweier Bauteile mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus der
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren zum Verbinden zweier Bauteile mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass es fertigungstechnisch insofern besonders vorteilhaft ist, da die Erzeugung der Oberflächenstruktur an dem ersten Bauteil und das Verbinden der beiden Bauteile während ein und demselben Arbeitsschritt in zeitlich aufeinanderfolgenden bzw. quasi simultanen Zeitabschnitten erfolgt. Mit anderen Worten gesagt bedeutet dies, dass es erfindungsgemäß nicht erforderlich ist, vor dem Fügen der beiden Bauteile in einem separaten Arbeitsgang an dem ersten Bauteil die Oberflächenstruktur, typischerweise an einem anderen Ort, auszubilden. Vielmehr wird diese während des Fügeprozesses bzw. während der Anordnung der beiden Bauteile zum Verbinden der Bauteile in einem zeitlich ersten Schritt an dem ersten Bauteil erzeugt, wonach anschließend nahezu zeitgleich ein Aufschmelzen des Materials des zweiten Bauteils und Ausfüllen bzw. Vermischen des Materials des zweiten Bauteils mit dem Material des ersten Bauteils bzw. das Eindringen des Kunststoffs in die Oberflächenstruktur erfolgt. Vorzugsweise erfolgt das bereichsweise Aufschmelzen des zweiten Bauteils und die Ausbildung der Oberflächenstruktur des ersten Bauteils zeitgleich mittels eines das zweite Bauteil durchstrahlendes Strahls der Strahlungsquelle. Insbesondere sind das erste und das zweite Bauteil derart angeordnet, dass der Laserstrahl zuerst das Kunststoffbauteil durchstrahlt, bevor der Laserstrahl auf den metallischen Partner in Form des ersten Bauteils trifft. Dabei durchstrahlt der Laserstrahl der Laserstrahlung zunächst den lasertransparenten Kunststoff des zweiten Bauteils und trifft anschließend auf die Oberfläche des metallischen Partners des ersten Bauteils. Im Bereich der Auftrittstelle findet aufgrund der eingebrachten Energie ein Umschmelz- und/oder Abtragsprozess im Metall derart statt, dass eine raue und zerklüftete Oberflächenstruktur an der Oberfläche des ersten Bauteils entsteht. In einer Variante wird durch die Laserstrahlung eine geordnete, geometrisch definierte Struktur ausgebildet. Insbesondere wird der Strahl der Strahlungsquelle mit einer vorbestimmten Trajektorie über den Fügebereich geführt.The method according to the invention for connecting two components with the features of claim 1 has the advantage that it is particularly advantageous in terms of production technology, since the creation of the surface structure on the first component and the connection of the two components during one and the same work step in chronologically successive or quasi simultaneous periods of time takes place. In other words, this means that, according to the invention, it is not necessary, before joining the two components, to form the surface structure on the first component in a separate operation, typically at a different location. Rather, it is generated on the first component during the joining process or during the arrangement of the two components to connect the components in a first step, after which the material of the second component is subsequently melted and the material of the second component is filled or mixed almost simultaneously takes place with the material of the first component or the penetration of the plastic into the surface structure. The melting of the second component in regions and the formation of the surface structure of the first component preferably take place simultaneously by means of a beam from the radiation source radiating through the second component. In particular, the first and the second component are arranged in such a way that the laser beam first shines through the plastic component before the laser beam strikes the metallic partner in the form of the first component. The laser beam of the laser radiation first shines through the laser-transparent plastic of the second component and then hits the surface of the metallic partner of the first component. In the area of the point of impact, due to the energy introduced, a remelting and / or removal process takes place in the metal in such a way that a rough and fissured surface structure is created on the surface of the first component. In one variant, the laser radiation forms an ordered, geometrically defined structure. In particular, the beam from the radiation source is guided over the joining area with a predetermined trajectory.
Somit schlägt es das erfindungsgemäße Verfahren zum Verbinden zweier Bauteile gemäß der Lehre des Anspruchs 1 vor, dass die Ausbildung der Oberflächenstruktur an dem ersten Bauteil in einem Zustand erfolgt, bei dem das zweite Bauteil sich in Anlagekontakt mit dem ersten Bauteil befindet.The method according to the invention for connecting two components according to the teaching of claim 1 thus proposes that the surface structure be formed on the first component in a state in which the second component is in abutment contact with the first component.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens zum Verbinden zweier Bauteile sind in den Unteransprüchen aufgeführt.Advantageous developments of the method according to the invention for connecting two components are listed in the subclaims.
Um zu gewährleisten, dass einerseits das aufgeschmolzene Material des zweiten Bauteils in die Oberflächenstruktur des ersten Bauteils eindringt, und andererseits die Soll-Position der beiden Bauteile während des Fügeprozesses eingehalten wird, ist es vorgesehen, dass zumindest während der Ausbildung der Oberflächenstruktur an dem ersten Bauteil und dem Aufschmelzen des Materials des zweiten Bauteils das zweite Bauteil mit einer Anlagekraft im Bereich der auszubildenden Oberflächenstruktur gegen das erste Bauteil kraftbeaufschlagt wird.In order to ensure that, on the one hand, the melted material of the second component penetrates into the surface structure of the first component, and on the other hand, the target position of the two components is maintained during the joining process, it is provided that at least during the formation of the surface structure on the first component and when the material of the second component is melted, a force is applied to the second component with a contact force in the area of the surface structure to be formed against the first component.
Um zu gewährleisten, dass bei in Anlagekontakt miteinander angeordneten Bauteilen die Oberflächenstruktur an dem ersten Bauteil ausgebildet werden kann, obwohl zwischen einer Strahlungsquelle (typischerweise einem Laserstrahl) und dem ersten Bauteil sich das das zweite Bauteil befindet, ist es vorgesehen, dass als Kunststoff für das zweite Bauteil ein für die Strahlungsquelle transparenter Kunststoff verwendet wird.In order to ensure that when components are in contact with one another, the surface structure can be formed on the first component, although the second component is located between a radiation source (typically a laser beam) and the first component provided that a plastic transparent to the radiation source is used as the plastic for the second component.
In Weiterbildung des zuletzt gemachten Vorschlags ist es vorgesehen, dass als Strahlungsquelle eine Laserstrahlquelle verwendet wird, und dass der Kunststoff zumindest im Wesentlichen ein faserloser oder faserverstärkter Thermoplast ist.In a further development of the proposal made last, it is provided that a laser beam source is used as the radiation source, and that the plastic is at least essentially a fiber-free or fiber-reinforced thermoplastic.
Hinsichtlich der genauen Geometrie der Oberflächenstruktur an dem ersten Bauteil gibt es unterschiedliche Möglichkeiten. In einer ersten Ausgestaltung des Verfahrens ist es vorgesehen, dass eine chaotische , d.h. eine unregelmäßig geformte Oberflächenstruktur erzeugt wird. Alternativ hierzu kann es jedoch auch vorgesehen sein, dass eine regelmäßig geometrische Strukturen aufweisende Oberflächenstruktur erzeugt wird. Bei der Oberflächenstruktur handelt es sich zum Beispiel um eine von einer Nanostruktur überlagerte Mikrostruktur. Es sind jedoch auch andere Strukturen denkbar, die zum Beispiel eine Makrostruktur umfassen.There are different possibilities with regard to the exact geometry of the surface structure on the first component. In a first embodiment of the method it is provided that a chaotic, i.e. an irregularly shaped surface structure is generated. As an alternative to this, however, it can also be provided that a surface structure having regular geometric structures is generated. The surface structure is, for example, a microstructure overlaid by a nanostructure. However, other structures are also conceivable which include a macrostructure, for example.
Um die Einwirkung der Strahlungsquelle, insbesondere des Laserstrahls, in der Fügezone zwischen den beiden Bauteilen sicherzustellen, sieht es ein weiteres bevorzugtes Verfahren vor, dass das Aufbringen der Anlagekraft in einem Bereich außerhalb der direkten Einwirkung der Strahlungsquelle auf das erste Bauteil erfolgt. Dadurch wird ein ungestörter Strahlengang ermöglicht. Alternativ kann ein für die Strahlungsquell transparentes Werkzeug eingesetzt werden, sodass dieses auch im Strahlengang der Strahlungsquelle angeordnet werden kann.In order to ensure the action of the radiation source, in particular the laser beam, in the joining zone between the two components, a further preferred method provides that the application force is applied in an area outside the direct action of the radiation source on the first component. This enables an undisturbed beam path. Alternatively, a tool that is transparent to the radiation source can be used so that it can also be arranged in the beam path of the radiation source.
Beispielsweise zur Verbesserung der Haftung zwischen den beiden Bauteilen oder zur Erzeugung bestimmter Oberflächeneigenschaften kann es darüber hinaus vorgesehen sein, dass die Oberfläche des ersten und/oder zweiten Bauteils vor dem Verbinden mit einer Oberflächenmodifikation versehen werden/wird. Eine derartige Oberflächenmodifikation kann beispielsweise durch eine chemische Behandlung des ersten und/oder zweiten Bauteils erfolgen.For example, in order to improve the adhesion between the two components or to produce certain surface properties, provision can also be made for the surface of the first and / or second component to be provided with a surface modification before the connection. Such a surface modification can take place, for example, by a chemical treatment of the first and / or second component.
Weiterhin umfasst die Erfindung einen Bauteileverbund, der nach einem soweit beschriebenen erfindungsgemäßen Verfahren hergestellt wurde.The invention further comprises a component assembly which has been produced according to a method according to the invention as described so far.
