Abstract

Die Erfindung betrifft ein Fügeverfahren zur Herstellung einer Bauteilverbindung, bei dem die Fügepartner (1, 3) an ihren einander zugewandten Fügeflächen (8) mittels eines langsamhärtenden Klebstoffes (2) zusammengefügt werden, welcher Klebstoff (2) in einem Aushärte-Zeitintervall unter Aufbau einer Verbindungsfestigkeit zumindest teilweise aushärtet, wobei zumindest ein Fügehilfselement (7) bereitgestellt wird, das während des Aushärte-Zeitintervalls die Fügepartner (1, 3) zueinander lagepositioniert. Erfindungsgemäß ist das Fügehilfselement ein von den Fügepartnern (1, 3) separates, insbesondere thermoplastisches Kunststoffbauteil (7), das bei thermischer oder chemischer Aktivierung unter Bildung einer schnellhärtenden Klebverbindung (K) zwischen den beiden Fügepartner (1, 3) plastifiziert und in einem Aushärte-Zeitintervall aushärtet, das kleiner als das Aushärte-Zeitintervall des langsamhärtenden Klebstoffes (2) ist.The invention relates to a joining method for producing a component connection, in which the joining partners (1, 3) are joined at their mutually facing joining surfaces (8) by means of a slow-curing adhesive (2), which adhesive (2) in a curing time interval under construction of a Bonding strength at least partially hardens, wherein at least one Joining auxiliary member (7) is provided, which positions the joining partners (1, 3) to each other during the curing time interval. According to the invention, the joining auxiliary element is a plastic component (7) which is separate from the joining partners (1, 3) and which plasticizes with thermal or chemical activation to form a fast-curing adhesive bond (K) between the two joining partners (1, 3) and in a hardening process Curing time interval that is smaller than the curing time interval of the slow-curing adhesive (2).

Description

Die Erfindung betrifft ein Fügeverfahren zur Herstellung einer Bauteilverbindung nach dem Oberbegriff des Patentanspruches 1 sowie eine solche Bauteilverbindung nach dem Patentanspruch 10.The invention relates to a joining method for producing a component connection according to the preamble of claim 1 and such a component connection according to claim 10.

Im Fahrzeug-Karosseriebau werden bei der Herstellung von Leichtbaustrukturen unter anderem faserverstärkte Kunststoffbauteile verwendet. Diese werden in gängiger Praxis durch langsamhärtende Zwei- oder Mehrkomponenten-Klebsysteme zusammengefügt, die unter Aufbau einer Verbindungsfestigkeit über mehrere Stunden hinweg auszuhärten sind.In vehicle body construction, fiber-reinforced plastic components are used in the manufacture of lightweight structures, among other things. These are put together in common practice by slow-curing two-component or multi-component adhesive systems which are to be cured for several hours while building up a bond strength.

In einer gattungsgemäßen Fügeprozess-Abfolge werden zunächst zwei faserverstärkte Kunststoffbauteile in eine Vorrichtung eingelegt. Anschließend wird zumindest eine der einander zugewandten Fügeflächen der Fügepartner mit dem Klebsystem appliziert und werden die beiden Fügepartner zusammengefügt und mittels Spanneinrichtungen gegeneinander lagerichtig verspannt. An die noch nicht ausgehärtete Bauteilverbindung werden Fügehilfselemente, zum Beispiel Klammern, montiert. Dann wird die Bauteilverbindung aus der Vorrichtung entnommen und zum Beispiel einem Durchlaufofen zugeführt, in dem eine Endaushärtung erfolgt.In a generic joining process sequence, first two fiber-reinforced plastic components are inserted into a device. Subsequently, at least one of the mutually facing joining surfaces of the joining partners is applied with the adhesive system and the two joining partners are assembled and clamped together by means of clamping devices against each other in the correct position. Fügehilfselemente, for example brackets mounted on the not yet cured component connection. Then the component connection is removed from the device and fed for example to a continuous furnace in which a final curing takes place.

Die Klammern übernehmen die Funktion der obigen Spanneinrichtungen in der Vorrichtung, nämlich eine lagerichtige Positionierung der beiden Fügepartner. Nach der Endaushärtung werden die Klammern von der Bauteilverbindung gelöst, von Klebstoff-Rückständen befreit und für den nächsten Klebevorgang bereitgestellt. Die Handhabung der Klammern, das heißt die Montage, Demontage sowie Reinigung ist mit fertigungstechnisch hohem Aufwand verbunden.The brackets assume the function of the above clamping devices in the device, namely a correct position positioning of the two joining partners. After final curing, the clamps are released from the component connection, removed from adhesive residue and provided for the next gluing process. The handling of the brackets, that is the assembly, disassembly and cleaning is associated with manufacturing technology high effort.

Aus der DE 10 2014 101 324 A1 ist ein Fügeverfahren bekannt, bei dem zwei thermoplastische Bauteile miteinander über einen Klebstoff verbunden sind. Zudem sind die beiden thermoplastischen Bauteile über eine Nietverbindung zusammengefügt. Die Nietverbindung ist durch einen im ersten Fügepartner ausgebildeten zylindrischen Vorsprung und durch eine dazu korrespondierende hohlzylindrische Aufnahmetasche im zweiten Fügepartner aufgebaut, in die der zylindrische Vorsprung des ersten Fügepartners eingesetzt ist. Anschließend erfolgt ein Heißnietverfahren, bei dem der Vorsprung des ersten Fügepartners mit der hohlzylindrischen Aufnahmetasche des zweiten Fügepartners verschmolzen wird. Aus der DE 11 2012 001 291 T5 ist ein weiteres Fügeverfahren bekannt, bei dem zwei Fügepartner über eine Klebstruktur miteinander verbunden sind. Die Klebstruktur weist einen schnellaushärtenden Klebstoff und einen langsam aushärtenden Klebstoff auf. Nach Aushärtung des schnellaushärtenden Klebstoffes wirkt dieser als ein Fügehilfselement, das eine lagerichtige Positionierung der beiden Fügepartner gewährleistet.From the DE 10 2014 101 324 A1 a joining method is known in which two thermoplastic components are connected to each other via an adhesive. In addition, the two thermoplastic components are joined together via a riveted joint. The rivet connection is constructed by a cylindrical projection formed in the first joining partner and by a correspondingly hollow cylindrical receiving pocket in the second joining partner into which the cylindrical projection of the first joining partner is inserted. Subsequently, a Heißnietverfahren takes place, in which the projection of the first joining partner is fused with the hollow cylindrical receiving pocket of the second joining partner. From the DE 11 2012 001 291 T5 Another joining method is known in which two joining partners are connected to one another via an adhesive structure. The adhesive structure has a fast curing adhesive and a slow curing adhesive. After curing of the fast-curing adhesive acts as a joining auxiliary element, which ensures a correct position positioning of the two joining partners.

Die Aufgabe der Erfindung besteht darin, ein Fügeverfahren sowie eine Bauteilverbindung bereitzustellen, bei der im Vergleich zum Stand der Technik in fertigungstechnisch einfacher Weise eine lagerichtige Bauteilverbindung ermöglicht ist.The object of the invention is to provide a joining method and a component connection, in which a positionally correct component connection is made possible in comparison to the prior art in a simple manufacturing technology.

Die Aufgabe ist durch die Merkmale des Patentanspruches 1 oder des Patentanspruches 10 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of claim 1 or claim 10. Preferred embodiments of the invention are disclosed in the subclaims.

Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist das Fügehilfselement ein von den beiden Fügepartnern separates insbesondere thermoplastisches Kunststoffbauteil, das bei normaler Prozessumgebungstemperatur formstabil bzw. fest ist. Das Kunststoffbauteil wird vor dem Zusammenfügen zwischen die beiden Fügepartner positioniert und anschließend thermisch oder chemisch aktiviert. Dadurch bildet sich eine schnellhärtende Klebverbindung, die in einem Aushärte-Zeitintervall aushärtet, das kleiner ist das Aushärte-Zeitintervall des langsamhärtenden Klebstoffes. Auf diese Weise wird das Kunststoffbauteil stoffschlüssig in die Bauteilverbindung integriert, so dass es nicht mehr davon demontierbar ist. Wie oben erwähnt, ist das Kunststoffbauteil bevorzugt aus einem Thermoplast gefertigt. Ein Thermoplast ist ein Polymer, das oberhalb einer spezifischen Temperatur biegbar und/oder formbar wird und beim Abkühlung in einen festen Zustand zurückkehrt.According to the characterizing part of claim 1, the joining auxiliary element is a separate from the two joining partners in particular thermoplastic plastic component which is dimensionally stable or solid at normal process ambient temperature. The plastic component is positioned before joining between the two joining partners and then activated thermally or chemically. As a result, a fast-curing adhesive bond is formed, which cures in a curing time interval which is smaller than the curing time interval of the slow-curing adhesive. In this way, the plastic component is integrally integrated into the component connection, so that it is no longer removable from it. As mentioned above, the plastic component is preferably made of a thermoplastic. A thermoplastic is a polymer that flexes and / or molds above a specific temperature and returns to a solid state upon cooling.

In einer technischen Umsetzung wird das Kunststoffbauteil vor dem Zusammenfügen der beiden Fügepartner an einer ihrer einander zugewandten Fügeflächen form- und/oder kraftschlüssig daran befestigt. Dies kann bei normaler Prozessumgebungstemperatur erfolgen, bei der das Kunststoffbauteil keine Kleb- oder Hafteigenschaften aufweist. Im Hinblick auf eine einfache Halterung des Kunststoffbauteil kann einer der Fügepartner in seiner Fügefläche eine Ausnehmung aufweisen, in die das Kunststoffbauteil vor dem Zusammenfügen der beiden Fügepartner einsteckbar ist.In a technical implementation, the plastic component is attached before the joining of the two joining partners on one of their mutually facing joining surfaces form and / or non-positively thereto. This can be done at normal process ambient temperature where the plastic component has no adhesive or adhesive properties. With regard to a simple mounting of the plastic component, one of the joining partners may have in its joining surface a recess into which the plastic component can be inserted before joining the two joining partners.

Bevorzugt ist das Kunststoffbauteil als ein Klebepin ausgeführt, der einen zum Beispiel zylindrischen Bauteilschaft aufweist, der in einen ausgeweiteten Bauteilkopf übergeht. Der Bauteilschaft des Klebepins kann in die oben erwähnte Ausnehmung im ersten Fügepartner eingesteckt werden, während der ausgeweitete Bauteilkopf die Ausnehmung an der Fügefläche überragt und ein Materialreservoir für die Klebeverbindung bildet.Preferably, the plastic component is designed as an adhesive pin, which has a cylindrical component shaft, for example, which merges into an expanded component head. The component shaft of the Klebepins can be inserted into the above-mentioned recess in the first joining partner, while the expanded component head projects beyond the recess on the joining surface and forms a material reservoir for the adhesive bond.

Bevorzugt ist das Kunststoffbauteil thermisch aktivierbar, das heißt durch einen Wärmeeintrag plastifizierbar sowie anschließend in einem kurzen Aushärte-Zeitintervall (zum Beispiel 40 Sekunden) bis Erreichen einer Tragfestigkeit aushärtbar. Aufgrund der Zwischenlage des Kunststoffbauteils zwischen den beiden Fügepartnern, die lediglich über die Klebstoffschicht geringer Materialdicke voneinander beabstandet sind, ist ein solcher Wärmeeintrag von außen in ausreichend kurzer Prozessdauer nur schwierig durchzuführen. Preferably, the plastic component is thermally activated, that is plasticizable by a heat input and then curable in a short curing time interval (for example, 40 seconds) until reaching a supporting strength. Due to the interposition of the plastic component between the two joining partners, which are spaced apart only via the adhesive layer of small material thickness, such heat input from the outside in a sufficiently short process time is difficult to perform.

Um einen prozesssicheren Wärmeeintrag in ausreichend kurzer Prozessdauer zu erzielen, kann die obige Ausnehmung im ersten Fügepartner, in die das Kunststoffbauteil einsetzbar ist, ein Vorloch sein, das sich durchgängig bis zu einer, von der Fügefläche abgewandten Fügepartner-Außenseite erstreckt. Das im ersten Fügepartner eingearbeitete Vorloch bildet somit eine Zugangsöffnung, über die das Kunststoffbauteil, insbesondere dessen Bauteilschaft, nach außen freigelegt ist. Auf diese Weise kann ein unmittelbarer Wärmeeintrag von außen in das Kunststoffbauteil erfolgen.In order to achieve a process-reliable heat input in a sufficiently short process time, the above recess in the first joint partner, in which the plastic component is used, be a pre-hole that extends continuously to a, facing away from the joining surface joining partner outside. The pre-hole incorporated in the first joining partner thus forms an access opening, via which the plastic component, in particular its component shaft, is exposed to the outside. In this way, an immediate heat input from outside into the plastic component can take place.

Der obige Wärmeeintrag in das Kunststoffbauteil kann in einer Prozessvariante durch ein Heißluftverfahren erfolgen, bei dem der Bauteilschaft des Kunststoffbauteils über die Zugangsöffnung im ersten Fügepartner mit Heißluft angeströmt wird. Alternativ dazu kann der Wärmeeintrag in das Kunststoffbauteil mit einer Infrarotbestrahlung erfolgen, bei der der Bauteilschaft mit Infrarotstrahlen beaufschlagt wird.The above heat input into the plastic component can take place in a process variant by a hot air method, in which the component shaft of the plastic component is flown through the access opening in the first joining partner with hot air. Alternatively, the heat input into the plastic component can take place with an infrared radiation, in which the component shaft is exposed to infrared rays.

Das langsamhärtende Klebstoffsystem zwischen den beiden Fügepartner und das bevorzugt thermoplastische Kunststoffbauteil können materialverschieden aufgebaut sein. Um die Funktionsfähigkeit des Klebstoffsystems sowie des Kunststoffbauteils nicht zu beeinträchtigen, ist es bevorzugt, wenn sich das Klebstoffsystem und das aufgeschmolzene Kunststoffbauteil nicht miteinander vermischen. Vor diesem Hintergrund kann beim Applizieren des langsamhärtenden Klebstoffsystems auf einen der beiden Fügepartner eine Freifläche freigehalten werden, auf die mit Abstand zum Klebstoffsystem die vom Kunststoffbauteil bereitgestellte Klebeverbindung realisiert wird.The slow-curing adhesive system between the two joining partners and the preferred thermoplastic plastic component may be constructed differently material. In order not to impair the functionality of the adhesive system and the plastic component, it is preferred if the adhesive system and the molten plastic component do not mix with each other. Against this background, when the slow-curing adhesive system is applied to one of the two joining partners, an open space can be kept free, to which the adhesive connection provided by the plastic component is realized at a distance from the adhesive system.

Wie oben erwähnt, wird nach erfolgtem Wärmeeintrag zumindest der zwischen den beiden Fügeflächen positionierte Bauteilkopf des Kunststoffbauteils verflüssigt oder plastifiziert, wodurch sich eine Klebeverbindung zwischen den beiden Fügepartnern ergibt. Bei der obigen Vorloch-Variante ist der Bauteilschaft des Kunststoffbauteils nach außen freigelegt. In diesem Fall ist es bevorzugt, wenn der Bauteilschaft im Wesentlichen flächenbündig mit dem Vorloch-Randbereich an der Fügepartner-Außenseite abschließt oder gegebenenfalls davon zurückgesetzt innerhalb des Vorlochs angeordnet ist. Auf diese Weise ergibt sich an der Fügepartner-Außenseite keine gegebenenfalls im weiteren Fertigungsverlauf nachteilige Störkontur.As mentioned above, after the heat has been introduced, at least the component head of the plastic component positioned between the two joining surfaces is liquefied or plasticized, resulting in an adhesive bond between the two joining partners. In the above pre-hole variant of the component shaft of the plastic component is exposed to the outside. In this case, it is preferable if the component shaft terminates essentially flush with the pre-hole edge region on the outside of the joining partner or, if appropriate, it is arranged inside the pre-hole. In this way, no disturbing contour, which may be disadvantageous in the further production process, results at the joining partner outside.

Das obige Fügeverfahren ist insbesondere beim Zusammenbau von faserverstärkten Kunststoffbauteilen oder generell von Kunststoffbauteilen von Vorteil, jedoch nicht alleine darauf beschränkt. Alternativ dazu kann das Fügeverfahren auch in einer Mischbauweise verwendet werden, bei der Fügepartner unterschiedlicher Materialpaarungen miteinander verbunden werden.The above joining method is particularly advantageous in the assembly of fiber-reinforced plastic components or in general of plastic components, but not limited thereto alone. Alternatively, the joining method can also be used in a mixed construction in which joining partners of different material pairings are connected to one another.

Die vorstehend erläuterten und/oder in den Unteransprüchen wiedergegebenen vorteilhaften Aus- und/oder Weiterbildungen der Erfindung können – außer zum Beispiel in den Fällen eindeutiger Abhängigkeiten oder unvereinbarer Alternativen – einzeln oder aber auch in beliebiger Kombination miteinander zur Anwendung kommen.The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the dependent claims can be used individually or else in any desired combination with one another, for example in the case of clear dependencies or incompatible alternatives.

Die Erfindung und ihre vorteilhaften Aus- und Weiterbildungen sowie deren Vorteile werden nachfolgend anhand von Zeichnungen näher erläutert.The invention and its advantageous embodiments and further developments and advantages thereof are explained in more detail below with reference to drawings.

1 in einer Seitenschnittdarstellung eine fertiggestellte Bauteilverbindung; und 1 in a side sectional view of a completed component connection; and

2 bis 4 jeweils Ansichten, die eine Prozessabfolge zur Herstellung der Bauteilverbindung veranschaulichen. 2 to 4 each views illustrating a process sequence for making the component connection.

In der 1 ist in Schnittdarstellung eine fertiggestellte Bauteilverbindung gezeigt, bei der ein erster Fügepartner 1, zum Beispiel eine Platine aus faserverstärktem Kunststoff, mit einem zweiten Fügepartner 3, zum Beispiel ebenfalls aus einem faserverstärkten Kunststoffbauteil, an einer Klebnaht 2 miteinander verklebt sind. Die Klebnaht 2 weist eine geringe Materialstärke m auf, so dass die beiden Fügepartner 1, 3 mit ihren einander zugewandten Fügeflächen 8 lediglich geringfügig voneinander beabstandet sind.In the 1 is a sectional view of a completed component connection shown in which a first joining partner 1 , For example, a board made of fiber-reinforced plastic, with a second joint partner 3 , for example also made of a fiber-reinforced plastic component, on an adhesive seam 2 glued together. The glue seam 2 has a low material thickness m, so that the two joining partners 1 . 3 with their mutually facing joining surfaces 8th only slightly spaced from each other.

Bei der Klebstoffnaht 2 kann beispielhaft ein Zwei- oder Mehrkomponenten-System eingesetzt werden, das langsamhärtend ist, das heißt in einem Aushärte-Zeitintervall von zum Beispiel mehreren Stunden aushärtbar ist. In dem Verlauf der Klebnaht 2 ist in der 1 ein Freiraum 9 freigehalten, in dem mittels eines Klebepins 7 eine im Vergleich zur Klebnaht 2 schnellhärtenden Klebverbindung K zwischen den beiden Fügepartner 1, 3 hergestellt ist. Der Klebepin 7 ist aus einem thermoplastischen Material hergestellt, das bei normaler Prozessumgebungstemperatur formstabil ist und erst bei einer thermischen Aktivierung, das heißt bei einem Wärmeeintrag H oberhalb einer Schmelztemperatur, plastifizierbar ist. Der Klebepin 7 ist daher in einem Aushärte-Zeitintervall aushärtbar, das wesentlich kleiner als das Aushärte-Zeitintervall des langsamhärtenden Klebstoffsystems 2 ist und in etwa bei zirka 40 Sekunden liegen kann.At the adhesive seam 2 For example, a two- or multi-component system can be used which is slow-curing, that is to say curable in a curing time interval of, for example, several hours. In the course of the glue seam 2 is in the 1 a free space 9 kept free, in which by means of a Klebepins 7 one compared to the glue seam 2 fast-curing adhesive bond K between the two joining partners 1 . 3 is made. The Klebepin 7 is made of a thermoplastic material which is dimensionally stable at normal process ambient temperature and only at a thermal activation, ie at a heat input H above a melting temperature, is plasticizable. The Klebepin 7 is therefore curable in a cure time interval that is substantially less than the cure time interval of the slow cure adhesive system 2 is about and can be about 40 seconds.

In der 1 weist der Klebepin 7 einen Bauteilschaft 11 sowie einen Bauteilkopf 13 auf. Der Bauteilschaft 11 ist durch ein Vorloch 15 im ersten Fügepartner 1 bis zu dessen Fügepartner-Außenseite 17 geführt. Der Fuß 19 des Bauteilschaftes 11 des Klebepins 7 ist in der 1 somit nach außen freigelegt und in etwa flächenbündig mit dem Vorloch-Randbereich an der Fügepartner-Außenseite 17 ausgerichtet.In the 1 has the Klebepin 7 a component shaft 11 as well as a component head 13 on. The component shaft 11 is through a pre-hole 15 in the first joining partner 1 up to its joining partner outside 17 guided. The foot 19 of the component shaft 11 the Klebepins 7 is in the 1 thus exposed to the outside and approximately flush with the pre-hole edge area at the joining partner outside 17 aligned.

Nachfolgend wird anhand der 2 bis 4 eine Prozesskette zur Herstellung der in der 1 gezeigten Bauteilverbindung beschrieben: So wird zunächst in der 2 der noch unverformte Klebepin 7 mit seinem Bauteilschaft 11 in das Vorloch 15 des ersten Fügepartners 1 eingesetzt, so dass der Bauteilkopf 13 des Klebepins 7 von der Fügefläche 8 des ersten Fügepartners 1 abragt (siehe 3). Anschließend wird auf der Fügefläche 8 des zweiten Fügepartners 3 eine, die Klebstoffnaht 2 bildende Kleberaupe appliziert, die aus dem langsamhärtenden Zwei- oder Mehrkomponenten-System aufgebaut ist.The following is based on the 2 to 4 a process chain for the production of in the 1 described component connection: Thus, first in the 2 the still undeformed Klebepin 7 with his component shaft 11 in the pre-hole 15 of the first joining partner 1 used, so that the component head 13 the Klebepins 7 from the joining surface 8th of the first joining partner 1 protrudes (see 3 ). Subsequently, on the joining surface 8th of the second joining partner 3 one, the glue seam 2 forming adhesive bead, which is composed of the slow-curing two- or multi-component system.

Im darauffolgenden Prozessschritt werden die beiden Fügepartner 1, 3 in einer nicht gezeigten Vorrichtung lagerichtig zusammengefügt, und zwar so, dass der Bauteilkopf 13 des Klebepins 7 in Kontakt mit einer im Kleberaupen-Verlauf ausgebildeten Freifläche 21 kommt. Gleichzeitig wird der Klebepin 7 in einem Heißluftverfahren bis auf eine Schmelztemperatur erwärmt. Hierzu wird Heißluft H unmittelbar auf den freigelegten Schaftfuß 19 des Klebepins 7 beaufschlagt. Beim Zusammenfügen der beiden Fügepartner 1, 3 ergibt sich im Bereich der Freifläche 21 die schnellhärtende Klebeverbindung K, die im Vergleich zur langsamhärtenden Kleberaupe 2 in einem sehr kurzen Aushärte-Zeitintervall aushärtet. Nach erfolgter Aushärtung wirkt die schnellhärtende Klebverbindung K bzw. das Kunststoffbauteil 7 als ein Fügehilfselement, das eine lagerichtige Positionierung der beiden Fügepartner 1, 3 so lange gewährleistet, bis die Klebstoffraupe 2 unter Aufbau einer Verbindungsfestigkeit zumindest teilweise ausgehärtet ist.In the following process step, the two join partners 1 . 3 assembled in the correct position in a device, not shown, in such a way that the component head 13 the Klebepins 7 in contact with a trained in Kleberaupen course open space 21 comes. At the same time the Klebepin 7 heated in a hot air process to a melting temperature. For this purpose, hot air H is directly on the exposed shaft foot 19 the Klebepins 7 applied. When assembling the two joining partners 1 . 3 results in the area of the open space 21 the fast-curing adhesive joint K, in comparison to the slow-curing adhesive bead 2 Cures in a very short curing time interval. After curing, the fast-curing adhesive bond K or the plastic component acts 7 as a joining auxiliary element, which is a positionally correct positioning of the two joining partners 1 . 3 ensured until the adhesive bead 2 at least partially cured under construction of a bond strength.
