Abstract

System comprising a metal sheet bound to another component by a layer or aggregate of heat-activatable adhesive comprises an IR source which irradiates the adhesive and/or edges of the materials being joined with a short, intensive dose of IR of wavelength 0.8 - 1.5 microns. Irradiation is carried out for at least long enough to harden the adhesive so that the joined composite can be handled

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer geklebten Verbundstruktur nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for producing a glued composite structure according to the preamble of the claim 1.

Das Kleben hat sich als einfache, kostengünstige und zuver­ lässige Verbindungstechnik unzählige Anwendungsgebiete auf verschiedensten Gebieten der Technik erschlossen. Seit eini­ gen Jahren werden im großen Maßstab auch Metallteile mitein­ ander oder mit Teilen aus anderen Materialien verklebt, bei­ spielsweise in der Automobil- und Flugzeugproduktion.Gluing has proven to be simple, inexpensive and reliable casual connection technology on countless areas of application different areas of technology opened up. Since some time Years ago, metal parts were also on a large scale other or glued to parts made of other materials, at for example in automobile and aircraft production.

Zu diesem Zweck kommen üblicherweise thermisch aktivierbare Klebstoffe, sogenannte Heiß- oder Schmelzkleber ("Hotmelts") zum Einsatz. Es handelt sich hierbei um Ein- oder Zweikompo­ nentensysteme, mit denen sich hohe Endfestigkeiten von mehr als 5 MPa zu günstigen Kosten und mit einfachen und leicht automatisierbaren technologischen Abläufen erzielen lassen.Thermally activatable devices are usually used for this purpose Adhesives, so-called hot or hot melt adhesives for use. It is a one or two compo systems with which high final strengths of more than 5 MPa at low cost and with simple and easy technological processes that can be automated.

Ein Problem dieser Klebstoffe besteht allerdings darin, daß sie bei Temperaturen oberhalb von 140 bis 180°C aktiviert werden müssen, um mindestens die sogenannte Handling-Festig­ keit (die im Automobilbau bei 1 MPa liegt) bzw. die soge­ nannte Auswaschfestigkeit, d. h. die Beständigkeit gegenüber Einwirkung von Wasser oder Lösungsmitteln, zu erreichen. Um diese Festigkeiten zu erzielen, werden die gefügten Teile mindestens kurzzeitig in geeigneten Öfen erhitzt. Für vo­ luminöse Teile, wie etwa vollständige Autokarosserien, han­ delt es sich dabei um einen höchst aufwendigen Schritt - sowohl was die Bereitstellung der entsprechenden Öfen als auch die Prozeßdauer und den logistischen Aufwand angeht.A problem with these adhesives, however, is that it is activated at temperatures above 140 to 180 ° C have to be at least the so-called Handling-Festig speed (which is 1 MPa in automotive engineering) or the so-called called washout resistance, d. H. the resistance to Exposure to water or solvents. Around To achieve this strength, the joined parts  heated at least briefly in suitable ovens. For vo luminous parts, such as complete car bodies, han it is a very complex step - both what the provision of the appropriate stoves as also the process duration and logistical effort.

Der Erfindung liegt daher die Aufgabe zugrunde, ein unaufwen­ diges, leicht an verschiedene Anwendungssituationen anpaßba­ res und vorteilhaft in vorgeprägte technologische Abläufe einfügbares Verfahren der gattungsgemäßen Art anzugeben.The invention is therefore based on the object, an unaufwen diges, easily adaptable to different application situations res and advantageous in pre-defined technological processes to specify an insertable method of the generic type.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst.This task is accomplished by a process with the characteristics of Claim 1 solved.

Die Erfindung schließt den grundlegenden Gedanken ein, die zu einer mindestens teilweisen thermischen Aktivierung des Kleb­ stoffs erforderlichen Temperaturen zumindest primär im Inne­ ren der Klebstoffschicht bzw. des Klebstoffaggregates zu er­ zeugen. Hierdurch wird dem Problem der sehr niedrigen Wärme­ leitfähigkeit der erwähnten Klebstoffe, die eine Durchwärmung des Klebstoffvolumens von den Umgebungsflächen her sehr er­ schwert, auf unkonventionelle Weise begegnet. Weiter schließt die Erfindung den Gedanken ein, hierzu energiereiche elektro­ magnetische Strahlung zu verwenden, für die die verwendeten Klebstoffe vergleichsweise transparent sind, so daß die Strahlung gut in das Innere des Klebstoffs eindringen kann. Nach den Untersuchungen der Erfinder gilt dies insbesondere für Strahlung im Bereich des nahen Infrarots (NIR), also mit einer Wellenlänge zwischen 0,8 und 1,5 µm.The invention includes the basic ideas involved in an at least partial thermal activation of the adhesive temperatures required at least primarily indoors Ren the adhesive layer or the adhesive aggregate testify. This eliminates the problem of very low heat Conductivity of the mentioned adhesives, which is a warmth of the adhesive volume from the surrounding areas very much sword, encountered in an unconventional way. Closes further the invention the idea of this, high-energy electro to use magnetic radiation for which the used Adhesives are comparatively transparent, so that the Radiation can penetrate well into the interior of the adhesive. According to the inventors' investigations, this applies in particular for radiation in the near infrared (NIR) range, i.e. with a wavelength between 0.8 and 1.5 µm.

Im Rahmen der Erfindung liegt es aber auch, unmittelbar an­ grenzende Bereiche der zu fügenden Teile mit dieser Strahlung (NIR-Strahlung) und über diese Teile schließlich den Kleb­ stoff selbst zu erwärmen. Für viele Anwendungen besonders bevorzugt ist eine Kombination aus der zuerst erwähnten direkten ("internen") und der zuletzt erwähnten indirekten ("externen") Erwärmung.In the context of the invention, however, it is also directly bordering areas of the parts to be joined with this radiation (NIR radiation) and finally the glue over these parts heat the fabric yourself. Especially for many applications a combination of the first-mentioned direct is preferred  ("internal") and the last mentioned indirect ("external") warming.

Bei direkter Bestrahlung der Klebstoffschichten bzw. -aggre­ gate wird bevorzugt mit einer Leistungsdichte im Bereich zwischen 50 und 500 kW/m2, insbesondere zwischen 100 und 200 kW/m2, gearbeitet. Handelt es sich bei den angrenzenden Bereichen der zu fügenden Teile um Metallflächen, so ist der Einsatz einer höheren Leistungsdichte im Bereich zwischen 500 kW/m2 und 2 MW/m2, insbesondere zwischen 750 kW/m2 und 1,5 MW/m2, zu bevorzugen.When the adhesive layers or aggregates are irradiated directly, a power density in the range between 50 and 500 kW / m 2 , in particular between 100 and 200 kW / m 2 , is preferably used. If the adjacent areas of the parts to be joined are metal surfaces, the use of a higher power density is in the range between 500 kW / m 2 and 2 MW / m 2 , in particular between 750 kW / m 2 and 1.5 MW / m 2 , to prefer.

Die Dauer der Bestrahlung liegt in Abhängigkeit von den Di­ mensionen, insbesondere der Dicke der Klebstoffschicht bzw. des Klebstoffaggregats im Bereich zwischen 0,5 und 30 s, ins­ besondere zwischen 2 und 10 s. Diese Werte gelten für Kleb­ stoff-Schichtdicken im Bereich zwischen 2 und 10 mm bzw. lo­ kalisierte Klebstoffaggregate bis zu ca. 10 mm Durchmesser bzw. Kantenlänge.The duration of the irradiation depends on the Di dimensions, in particular the thickness of the adhesive layer or of the adhesive aggregate in the range between 0.5 and 30 s, ins special between 2 and 10 s. These values apply to adhesive fabric layer thicknesses in the range between 2 and 10 mm or lo calibrated adhesive aggregates up to approx. 10 mm in diameter or edge length.

Zur Erzeugung der NIR-Strahlung werden in besonders einfacher und kostengünstiger Weise weitgehend konventionelle Halogen­ lampen eingesetzt, die zur Einstellung des gewünschten Strah­ lungsspektrums insbesondere mit erhöhter Betriebstemperatur betrieben werden. In Abstimmung auf die Geometrie der zu be­ handelnden Klebstoffschicht werden Flächen- oder Linien- oder Punktstrahler oder eine Kombination aus solchen eingesetzt. Eine Fokussierung der Strahlung wird hier durch geeignet ge­ krümmte Reflektoren erreicht. Zweckmäßigerweise wird jeweils für eine bestimmte Anwendung eine der Geometrie der zu fügen­ den Teile und der Klebstoffschichten- bzw. aggregate ange­ paßte Gesamt-Bestrahlungsgeometrie entworfen und ausgeführt.To generate the NIR radiation are particularly easy and inexpensive way largely conventional halogen lamps used to set the desired beam tion spectrum especially with increased operating temperature operate. In line with the geometry of the be acting adhesive layer are surface or line or Spotlights or a combination of such. A focus of the radiation is here by suitable ge curved reflectors reached. It is expedient in each case for one specific application to add one of the geometry of the the parts and the adhesive layers or aggregates The overall radiation geometry was designed and implemented.

Die spektrale Zusammensetzung der Strahlung entspricht (wie oben bereits erwähnt) grundsätzlich in vorteilhafter Weise dem Anwendungszweck, sie ist aber insbesondere durch Änderung der Betriebstemperatur der Halogenlampe(n) oder auch durch Einsatz von Filtern auf die spezifischen Absorptionseigen­ schaften des eingesetzten Klebstoffs - und wahlweise zusätz­ lich auf die Absorptionseigenschaften eines gegebenenfalls von der Strahlung teilweise durchdrungenen angrenzenden Tei­ les - einstellbar. Das Ziel besteht hierbei darin, eine im wesentlichen gleichmäßige Durchwärmung der Klebstoffschicht bzw. des Klebstoffaggregates in kürzester Zeit zu erreichen.The spectral composition of the radiation corresponds (as already mentioned above) in principle in an advantageous manner  the application purpose, but it is particularly due to change the operating temperature of the halogen lamp (s) or by Use of filters on the specific absorption properties properties of the adhesive used - and optionally additional Lich on the absorption properties of a possibly adjacent part partially penetrated by the radiation les - adjustable. The goal here is to create a substantially uniform heating of the adhesive layer or the adhesive aggregate can be reached in the shortest possible time.

Für viele Anwendungen ist eine solche NIR-Strahlungsbehand­ lung des Klebstoffs ausreichend, daß lediglich die benötigte Handling-Festigkeit bzw. die Auswaschfestigkeit, nicht aber die geforderte Endfestigkeit der Verbindung durch diese Be­ handlung erreicht wird. Beispielsweise bei der Herstellung von Kraftfahrzeugkarosserien kann die Endfestigkeit in güns­ tiger Weise im Rahmen der thermischen Behandlung des gesamten Fahrzeugs zur Trocknung des Lacks erzeugt werden. Das vor­ geschlagene Verfahren kann daher mit sehr kurzen Prozeßdauern auskommen.Such an NIR radiation treatment is for many applications sufficient of the adhesive that only the required Handling strength or washout resistance, but not the required final strength of the connection through this loading action is achieved. For example in the manufacture The final strength of car bodies can be specified in güns tiger as part of the thermal treatment of the whole Vehicle for drying the paint are generated. That before Proposed procedures can therefore have very short process times get along.

Dies ermöglicht insbesondere auch eine abtastende Behandlung von langgestreckten Klebstoffspuren, wie sie beispielsweise längs größerer Karosserieteile vorkommen. Dabei wird die Be­ strahlungseinrichtung insbesondere koordinatengesteuert dem Verlauf der Klebstoffspur nachgeführt oder umgekehrt der vor­ gefügte Verbund aus dem ersten und zweiten Teil gesteuert an der Bestrahlungseinrichtung entlanggeführt.In particular, this also enables a scanning treatment of elongated traces of adhesive, such as, for example occur along larger body parts. The Be radiation device in particular controlled by coordinates Follow the course of the adhesive track or vice versa joined composite from the first and second part controlled guided along the irradiation device.

Die thermische Effizienz des Verfahrens kann erhöht und die Behandlungsdauer damit nochmals verkürzt werden, indem min­ destens eines der zu fügenden Teile in dem den Klebstoffauf­ trag benachbarten Bereich vorgewärmt und somit der Wärmeab­ fluß während der NIR-Bestrahlung verringert wird. The thermal efficiency of the process can be increased and the Treatment time can be shortened again by min at least one of the parts to be joined in which the adhesive preheated adjacent area and thus the heat flow is reduced during the NIR irradiation.  

Bei der Verbindung von zwei Metallteilen miteinander (bei­ spielsweise zweier Karosserieteile oder eines Karosserie- und eines Fahrgestellteiles eines Kraftfahrzeuges) ergibt sich eine besonders vorteilhafte Verfahrensführung, wenn die bei­ den Teile einander längs einer vorgesehenen Verbindungslinie nicht vollständig überlappen und angrenzend an den freiblei­ benden Bereich eine Klebstoffspur oder Klebstoffaggregate oder Abschnitte einer ausgedehnteren Klebstoffschicht vorge­ sehen sind, die vom freibleibenden Bereich aus sichtbar bzw. zugänglich sind. Auf diese Klebezonen wird die Strahlung nach dem Zusammenfügen der Teile ausgerichtet, um dort eine Akti­ vierung und die Bildung von die Handling- bzw. Auswaschfes­ tigkeit begründenden Verbindungsabschnitten zu bewirken.When connecting two metal parts together (at for example, two body parts or a body and of a chassis part of a motor vehicle) results a particularly advantageous procedure when the at the parts together along an intended connecting line not completely overlap and adjacent to the lead a glue trail or glue aggregates or portions of a more extensive layer of adhesive are visible that are visible or visible from the are accessible. The radiation is reflected on these adhesive zones the assembly of the parts aligned to an act there vation and the formation of the handling or washout to effect connecting sections.

Sowohl hierbei als auch in Ausführungen, bei denen nur eines der zu fügenden Teile aus Metall besteht, ist weiterhin eine Verfahrensführung von Vorteil, bei der eine Reflexion eines Teils der NIR-Strahlung durch eine an die Klebstoffschicht angrenzende metallische Oberfläche bewirkt und zur Vergrö­ ßerung der Strahlungsdichte innerhalb des Klebstoffs ausge­ nutzt wird. Hierdurch kann beispielsweise bei der erwähnten Konfiguration zweier nicht vollständig überlappender Metall­ teile seitlich eingestrahlte NIR-Strahlung bei geeignetem Einstrahlungswinkel durch Mehrfachreflexionen relativ weit in den Zwischenraum zwischen beiden Teilen und die dort befind­ liche Klebstoffschicht hinein transportiert werden, so daß eine Aktivierung (und Trocknung bzw. Vernetzung) keineswegs nur im äußersten Kantenbereich, sondern auch noch in be­ trächtlichem Abstand von diesem erreicht werden kann.Both here and in versions in which only one the parts to be joined are made of metal, is still one Procedure management is advantageous, in which a reflection of a Part of the NIR radiation through an on the adhesive layer adjacent metallic surface causes and to enlarge Radiation density within the adhesive is used. In this way, for example, in the aforementioned Configuration of two not completely overlapping metal parts laterally irradiated NIR radiation with suitable Irradiation angle due to multiple reflections relatively far in the space between the two parts and the one located there Liche adhesive layer are transported into it, so that activation (and drying or crosslinking) in no way only in the outermost edge area, but also in be distance from this can be achieved.

Bei Anwendungen, wo ein metallisches erstes Teil mit einem aus Kunststoff bestehenden, insbesondere großflächigen, zwei­ ten Teil verbunden werden muß, kann eine solche Positionie­ rung der Teile - und damit des Klebstoffauftrages - relativ zur Bestrahlungseinrichtung zweckmäßig sein, daß das zweite Teil mindestens teilweise von der Strahlung durchsetzt wird, bevor diese auf den Klebstoff trifft. Hierbei kann der Um­ stand ausgenutzt werden, daß die Absorptionseigenschaften des Kunststoffteils sich von denjenigen des Klebstoffs erheblich unterscheiden können, so daß die NIR-Strahlung das Kunst­ stoffteil ohne nennenswerte Absorption und somit ohne nach­ teilige Erwärmung desselben durchdringen kann.In applications where a metallic first part with a made of plastic, especially large, two such a position can be connected parts - and thus the adhesive application - relatively to the irradiation device that the second  Part is at least partially penetrated by the radiation, before it hits the glue. Here, the order stood to be exploited that the absorption properties of the Plastic part differs significantly from that of the adhesive can distinguish so that the NIR radiation art fabric part without significant absorption and therefore without after partial heating of the same can penetrate.

Eine Einstellung der Strahlungsleistung der Bestrahlungsein­ richtung erfolgt zweckmäßigerweise durch Variation des Ab­ standes zwischen der Strahlungsquelle und der Klebstoff­ schicht bzw. dem Klebstoffaggregat. Grundsätzlich ist eine Einstellung auch über die Änderung der Betriebsspannung und -temperatur der vorzugsweise eingesetzten Halogenlampen mög­ lich. Hiermit wird aber zugleich das Emissionspektrum verän­ dert - was im Hinblick auf die vorteilhafte Abstimmung auf die Absorptionseigenschaften des Klebstoffs unerwünscht sein kann.A setting of the radiation power of the irradiation unit direction is expediently done by varying the Ab between the radiation source and the adhesive layer or the adhesive aggregate. Basically is one Setting also by changing the operating voltage and temperature of the preferably used halogen lamps possible Lich. This also changes the emission spectrum changes - what with regard to the advantageous coordination the absorption properties of the adhesive may be undesirable can.

Eine spezielle Anwendung des vorgeschlagenen Verfahrens sieht vor, daß in entsprechende Ausnehmungen des ersten und/oder zweiten Teils eng lokalisierte Klebstoffaggregate als provi­ sorische Verbinder (sogenannte "strukturelle Pins") eingefügt und diese anschließend einer entsprechend lokalisierten Strahlung ausgesetzt werden. Durch diese Bestrahlung werden sie mindestens in einem zum "Zusammenheften" der Teile mit der erforderlichen Handling-Festigkeit ausreichenden Maße ak­ tiviert und vernetzt.A specific application of the proposed method provides before that in corresponding recesses of the first and / or second part closely localized adhesive aggregates as provi sorean connectors (so-called "structural pins") inserted and then locate them accordingly Exposed to radiation. Be through this radiation them in at least one for "stitching" the parts together the required handling strength sufficient dimensions ak activated and networked.

Eine weitere interessante Anwendung des vorgeschlagenen Ver­ fahrens besteht in der Aushärtung von Vergußmassenklebern, wie sie zum Schließen kleinerer Hohlräume oder zum Vergießen von Konstruktionsteilen eingesetzt werden. Another interesting application of the proposed ver driving consists in the curing of casting compound adhesives, like they are used to close smaller cavities or for potting of construction parts.  

In den oben erwähnten Anwendungen erfolgt die aktivierende NIR-Bestrahlung bevorzugt nach dem Zusammenfügen der zu ver­ bindenden Teile, für spezielle Anwendungen ist aber auch eine Aktivierung des nur auf ein Teil aufgetragenen Klebstoffs un­ mittelbar vor dem Anfügen des anderen Teils möglich und sinn­ voll.In the applications mentioned above, the activating is done NIR radiation preferred after joining the ver binding parts, but also for special applications Activation of the adhesive applied to only one part indirectly possible and sensible before adding the other part full.

Bei den mit den vorgeschlagenen Verfahren behandel- und ak­ tivierbaren Klebstoffsystemen handelt es sich um bekannte und handelsübliche Systeme vom thermisch vernetzenden Typ, insbe­ sondere auf PU- oder Epoxidbasis. Gleichwohl kann die Ent­ wicklung von speziell auf die Emissionsspektren der bevorzugt als Strahlungsquellen eingesetzten Halogenlampen abgestimmten Systemen sinnvoll sein.For those treated with the proposed procedures and ak tivable adhesive systems are known and commercially available systems of the thermal crosslinking type, esp especially based on PU or epoxy. Nevertheless, the Ent development of special on the emission spectra of the preferred halogen lamps used as radiation sources Systems make sense.

Die Ausführung der Erfindung ist nicht auf die oben beschrie­ benen Anwendungsbeispiele und Aspekte beschränkt, sondern ebenso in einer Vielzahl von Abwandlungen derselben sowie weiteren Anwendungen möglich.The implementation of the invention is not described above limited application examples and aspects, but likewise in a multitude of modifications of the same as well other applications possible.
