Description

BESCHREIBUNG DESCRIPTION
Applikator zur Applikation einer Dichtmasse auf eine Bördelnaht und zugehöriges BetriebsverfahrenApplicator for applying a sealant to a flanged seam and associated operating method
Die Erfindung betrifft einen Applikator zur Applikation eines Beschichtungsmittels auf ein Bauteil, insbesondere zur Appli- kation einer Dichtmasse auf eine Bördelnaht an einer Rückseite eines Kraftfahrzeug-Karosseriebauteils, wobei der Applikator insbesondere durch einen Spalt zwischen zwei überlappenden Kraftfahrzeug-Karosseriebauteilen hindurch ragen kann.The invention relates to an applicator for applying a coating composition to a component, in particular for applying a sealing compound to a flanged seam on a rear side of a motor vehicle body component, wherein the applicator can protrude through a gap between two overlapping motor vehicle body components in particular.
Kraftfahrzeug-Karosseriebauteile (z.B. Türen oder Hauben) weisen oftmals sogenannte Bördelnähte auf, bei denen ein Blechteil um eine Kante eines anderen Blechteils herum gebördelt ist, wobei die beiden Blechteile dann miteinander verklebt sein können. Hierbei besteht die Gefahr, dass Feuchtig- keit in den Spalt zwischen den beiden Blechteilen eindringt und dort zu Korrosion führt. Es ist deshalb bekannt, eine Dichtmasse auf die Bördelnaht zwischen den beiden Blechteilen aufzubringen, um die Bördelnaht abzudichten und dadurch das Eindringen von Feuchtigkeit und damit verbundene Korrosion sicher zu verhindern.Automotive body parts (e.g., doors or hoods) often have so-called flared seams in which a sheet metal part is crimped around an edge of another sheet metal part, with the two sheet metal parts then being glued together. There is a risk that moisture will penetrate into the gap between the two sheet metal parts and lead to corrosion there. It is therefore known to apply a sealant to the hemming seam between the two sheet metal parts to seal the hemming seam and thereby reliably prevent the ingress of moisture and associated corrosion.
Die Applikation der Dichtmasse auf die Bördelnaht erfolgt bei der Beschichtung von Türen von Kraftfahrzeugkarosserien in der Praxis manuell durch Werker, die zunächst die jeweilige Tür öffnen und dann die Dichtmasse manuell auf die Bördelnaht auftragen. Sofern sich die Bleche nicht überlappen, ist auch eine manuelle Applikation bei geschlossener Tür möglich. Nachteilig an dieser manuellen Applikation der Dichtmasse auf die Bördelnaht sind jedoch der hohe personelle Aufwand und die damit verbundenen Kosten.The application of the sealant to the hemming seam is done in the coating of doors of motor vehicle bodies in practice manually by workers who first open the respective door and then manually apply the sealant to the hemming seam. If the sheets do not overlap, a manual application is also possible with the door closed. However, a disadvantage of this manual application of the sealant to the flanged seam are the high personnel costs and the associated costs.
Darüber hinaus wurden im Stand der Technik Versuche unternommen, um die Dichtmasse automatisch durch einen Beschichtungs- roboter auf die Bördelnaht aufzubringen. Diese Versuche zur Automatisierung der Applikation der Dichtmasse sind jedoch bisher in der Praxis aus verschiedenen Gründen mit erhebli- chen Problemen verbunden.In addition, attempts have been made in the prior art to apply the sealant automatically to the hemming seam by a coating robot. However, these attempts to automate the application of the sealant have hitherto been associated with considerable problems in practice for various reasons.
Zum Einen konnte die Dichtmasse bei Türen und Hauben von Kraftfahrzeugkarosserien nur dann auf die Bördelnaht aufgebracht werden, wenn die Türen bzw. Hauben zuvor geöffnet wer- den, was mit einem zusätzlichen Aufwand verbunden ist.On the one hand, the sealant in doors and hoods of motor vehicle bodies could only be applied to the hemming seam when the doors or hoods are opened beforehand, which involves an additional outlay.
Zum Anderen erfordert die Applikation der Dichtmasse auf die Bördelnaht eine extrem hohe Positionierungsgenauigkeit des verwendeten Beschichtungsroboters, die nur durch eine sensor- gestützte Positionsregelung mit einer Nachführung der Roboterposition entsprechend den ermittelten Positionsabweichungen möglich ist. Bei einer automatischen Applikation der Dichtmasse auf die Bördelnaht stellt der apparative Aufwand zur Erreichung der erforderlichen Positionierungsgenauigkeit die aufgrund der Personaleinsparung erzielbare Wirtschaftlichkeit in Frage.On the other hand, the application of the sealing compound to the hemming seam requires an extremely high positioning accuracy of the coating robot used, which is possible only by a sensor-based position control with a tracking of the robot position corresponding to the determined position deviations. In an automatic application of the sealant to the hemming seam of the equipment required to achieve the required positioning accuracy achievable due to the savings in manageable economy in question.
Aus dem älteren, nachveröffentlichten Patent DE 10 2007 037 865 B3 ist ferner ein Applikator bekannt, der eine automati- sehe, robotergestützte Applikation von Dichtmasse auf eine Bördelnaht ermöglicht. Hierzu weist der bekannte Applikator ein nachgiebiges Gelenk auf, wodurch die Anforderungen an die Positionierungsgenauigkeit des verwendeten Roboters auf ein vertretbares Maß reduziert werden. Problematisch bei der Abdichtung von Bördelnähten im Bereich von Kraftfahrzeugtüren ist die Tatsache, dass sich die Kraftfahrzeugtüren im geschlossenen Zustand aufgrund des crash- freundlichen Aufbaus der Kraftfahrzeugtüren hinter den jeweiligen Kotflügel schieben. Dies hat zur Folge, dass der patentgemäße Applikator gemäß DE 10 2007 037 865 B3 nicht durch den Spalt zwischen der Kraftfahrzeugtür und dem Kotflügel hindurchgeschoben werden kann, da diese Bauteile einander ü- berlappen. Bei der Abdichtung von Bördelnähten im Bereich von Kraftfahrzeugtüren müssen die Kraftfahrzeugtüren deshalb bisher geöffnet werden, um die Bördelnähte für die Applikation der Dichtmasse zugänglich zu machen.From the older, postpublished patent DE 10 2007 037 865 B3 also an applicator is known, which allows an automatic see robot-based application of sealant on a hemming seam. For this purpose, the known applicator on a resilient joint, whereby the requirements for the positioning accuracy of the robot used are reduced to an acceptable level. The problem with the sealing of flanged seams in the area of motor vehicle doors is the fact that the motor vehicle doors in the closed state slide behind the respective fender due to the crash-friendly construction of the motor vehicle doors. This has the consequence that the patent applicator according to DE 10 2007 037 865 B3 can not be pushed through the gap between the motor vehicle door and the fender, as these components Ü overlap each other. In the sealing of flanged seams in the range of motor vehicle doors, therefore, the motor vehicle doors have to be opened so far in order to make the flanged seams accessible for the application of the sealing compound.
Das öffnen der Kraftfahrzeugtüren für die Applikation der Dichtmasse auf die jeweilige Bördelnaht erfordert jedoch Taktzeit, die für die eigentliche Applikation der Dichtmasse verloren geht. Dies kann unter Umständen dazu führen, dass für die Applikation der Dichtmasse auf die verschiedenen Bör- delnähte der Kraftfahrzeugkarosserie mehrere Arbeitstakte erforderlich sind.However, the opening of the motor vehicle doors for the application of the sealant to the respective flanged seam requires cycle time, which is lost for the actual application of the sealant. Under certain circumstances, this can mean that several work cycles are required for the application of the sealant to the various stock seams of the motor vehicle body.
Darüber hinaus erfordert das Öffnen der Kraftfahrzeugtüren für die Applikation der Dichtmasse auf die Bördelnähte einen zusätzlichen Handhabungsroboter, was mit erhöhten Investitionskosten und einem größeren Platzbedarf in der Lackieranlage verbunden ist.In addition, the opening of the vehicle doors for the application of the sealant to the flanged seams requires an additional handling robot, which is associated with increased investment costs and a larger footprint in the paint shop.
Ferner ist zum Stand der Technik noch hinzuweisen auf US 2 968 441.Further, the prior art should be noted on US 2,968,441.
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Applikator zu schaffen, der es ohne Öffnen einer Kraftfahrzeug- tür ermöglicht, eine auf der Rückseite der Kraftfahrzeugtür befindliche Bördelnaht mit Dichtmasse abzudichten.The invention is therefore based on the object to provide an applicator, which it without opening a motor vehicle door makes it possible to seal a flanged seam located on the rear side of the motor vehicle door with sealing compound.
Allgemein liegt der Erfindung die Aufgabe zugrunde, einen Ap- plikator zu schaffen, der durch einen Spalt zwischen überlappenden Bauteilen hindurch ragen kann, um auf der Rückseite der Bauteile ein Beschichtungsmittel (z.B. Dichtmasse) zu applizieren.The general object of the invention is to provide an applicator which can project through a gap between overlapping components in order to apply a coating agent (for example sealing compound) to the back of the components.
Darüber hinaus liegt der Erfindung die Aufgabe zugrunde, ein Betriebsverfahren für einen derartigen Applikator anzugeben.In addition, the invention has for its object to provide an operating method for such an applicator.
Diese Aufgabe wird durch einen erfindungsgemäßen Applikator bzw. ein entsprechendes Betriebsverfahren gemäß den nebenge- ordneten Ansprüchen gelöst.This object is achieved by an applicator according to the invention or a corresponding operating method according to the subordinate claims.
Die Erfindung umfasst die allgemeine technische Lehre, den Applikator so zu gestalten, dass der Applikator auch durch einen Spalt zwischen überlappenden Bauteilen hindurch von der Vorderseite auf die Rückseite der Bauteile ragen kann, um auf der Rückseite der Bauteile Beschichtungsmittel zu applizieren. Beispielsweise kann der Applikator hierbei in Längsrichtung der Bördelnaht in den Spaltbereich eingeführt werden, was beispielsweise am stirnseitigen Ende eines Spaltbereichs möglich ist.The invention encompasses the general technical teaching of configuring the applicator so that the applicator can also protrude from the front side to the back side of the components through a gap between overlapping components in order to apply coating agent to the back side of the components. For example, the applicator can be introduced in the longitudinal direction of the hemming seam in the gap region, which is possible, for example, at the front end of a gap region.
Die Erfindung sieht deshalb einen Düsenträger (z.B. ein Rohr) vor, der mehrfach gekrümmt ist und es dadurch ermöglicht, die von dem Düsenträger geführte Düse durch den Spalt zwischen den überlappenden Bauteilen hindurch auf der Rückseite derThe invention therefore provides a nozzle carrier (e.g., a tube) that is multi-curved, thereby allowing the nozzle guided by the nozzle carrier to pass through the gap between the overlapping components on the back side of the nozzle
Bauteile zu positionieren, um dort Beschichtungsmittel zu applizieren. Vorzugsweise ist der Düsenträger im Wesentlichen doppel-L- förmig, d.h. der Düsenträger besteht im Wesentlichen aus zwei aneinander angrenzenden, jeweils L-förmigen Abschnitten. Es ist jedoch alternativ auch möglich, dass der Düsenträger im Wesentlichen S-förmig ist. Entscheidend ist lediglich, dass der Düsenträger so geformt ist, dass der Düsenträger die Düse durch den Spalt zwischen den benachbarten überlappenden Bauteilen hindurch auf der Rückseite der Bauteile in der für den Beschichtungsprozess erforderlichen Weise positionieren kann.Position components to apply there coating agent. Preferably, the nozzle carrier is substantially double L-shaped, ie the nozzle carrier consists essentially of two adjacent, each L-shaped sections. However, it is alternatively also possible that the nozzle carrier is substantially S-shaped. What is decisive is that the nozzle carrier is shaped so that the nozzle carrier can position the nozzle through the gap between the adjacent overlapping components on the back of the components in the manner required for the coating process.
In einem bevorzugten Ausführungsbeispiel weist der Düsenträger an seinem distalen Ende einen im Wesentlichen U-förmigen Abschnitt mit einem distalen Schenkel, einem proximalen Schenkel und einem Verbindungsschenkel auf, wobei der Verbin- dungsschenkel den proximalen Schenkel mit dem distalen Schenkel verbindet. Im Betrieb umgreift der U-förmige Abschnitt des Düsenträgers dann eine Seitenkante des zu beschichtenden Bauteils durch einen Spalt hindurch, so dass sich der distale Schenkel mit der Düse hinter dem zu beschichtenden Bauteil und der proximale Schenkel vor dem zu beschichtenden Bauteil befindet, während der Verbindungsschenkel des U-förmigen Abschnitts durch den Spalt hindurchragt. Hierbei ist die Düse an dem distalen Schenkel des U-förmigen Abschnitts angeordnet bzw. direkt in diesen integriert und gibt das Beschichtungs- mittel von hinten nach vorne auf die Rückseite des zu beschichtenden Bauteils ab. Der proximale Schenkel und/oder der distale Schenkel des U-förmigen Abschnitts des Düsenträgers haben vorzugsweise eine Schenkellänge von mehr als 2cm, 4cm, 6cm oder mehr als 10cm, wobei die vorteilhafte Schenkellänge von der Bauteilgeometrie abhängt.In a preferred embodiment, the nozzle carrier has at its distal end a substantially U-shaped section with a distal leg, a proximal leg and a connecting leg, wherein the connecting leg connects the proximal leg to the distal leg. In operation, the U-shaped portion of the nozzle carrier then surrounds a side edge of the component to be coated through a gap, so that the distal leg with the nozzle behind the component to be coated and the proximal leg in front of the component to be coated, while the connecting leg of the U-shaped section protrudes through the gap. In this case, the nozzle is arranged on the distal leg of the U-shaped section or integrated directly into it, and dispenses the coating agent from the back to the front onto the rear side of the component to be coated. The proximal leg and / or the distal leg of the U-shaped portion of the nozzle carrier preferably have a leg length of more than 2cm, 4cm, 6cm or more than 10cm, the advantageous leg length depending on the component geometry.
In dem vorstehend beschriebenen bevorzugten Ausführungsbeispiel mit einem U-förmigen Abschnitt an dem distalen Ende des Düsenträgers weist der Düsenträger vorzugsweise drei Krümmun- gen auf, nämlich - von der Düse ausgehend - zunächst zwei Krümmungen mit derselben Krümmungsrichtung und dann eine Krümmung mit einer entgegengesetzten Krümmungsrichtung. Die Erfindung ist jedoch hinsichtlich des Düsenträgers nicht auf eine bestimmte Anzahl von Krümmungen beschränkt. Vielmehr um- fasst die Erfindung auch Applikatoren mit einem Düsenträger mit zwei oder mehr als drei Krümmungen. Entscheidend ist lediglich, dass der Düsenträger so geformt ist, dass er durch einen Spalt zwischen zwei benachbarten, seitlich überlappen- den Bauteilen hindurch auf die Rückseite der Bauteile ragen kann.In the preferred embodiment described above with a U-shaped section at the distal end of the nozzle carrier, the nozzle carrier preferably has three curvatures. on, namely - starting from the nozzle - first two curvatures with the same direction of curvature and then a curvature with an opposite direction of curvature. However, the invention is not limited to a certain number of curvatures with respect to the nozzle carrier. Rather, the invention also encompasses applicators with a nozzle carrier having two or more than three curvatures. All that matters is that the nozzle carrier is shaped in such a way that it can protrude through a gap between two adjacent, laterally overlapping components onto the rear side of the components.
Zwischen den einzelnen Krümmungen weist der Düsenträger vorzugsweise im Wesentlichen gerade Abschnitte auf, jedoch kann im Rahmen der Erfindung in Abhängigkeit von der Bauteilgeometrie im Bereich des Spalts auch ein kontinuierlich gekrümmter Düsenträger zum Einsatz kommen.The nozzle carrier preferably has essentially straight sections between the individual curvatures, however, a continuously curved nozzle carrier can also be used within the scope of the invention, depending on the component geometry in the region of the gap.
Weiterhin sind die einzelnen Krümmungen des Düsenträgers vor- zugsweise im Wesentlichen rechtwinklig. Es ist jedoch alternativ auch möglich, dass die einzelnen Krümmungen des Düsenträgers jeweils einen Krümmungswinkel von mindestens 70° oder mindestens 80° aufweisen. Darüber hinaus ist es möglich, dass die einzelnen Krümmungen des Düsenträgers jeweils einen Krüm- mungswinkel von höchstens 110° oder höchstens 100° aufweisen.Furthermore, the individual curvatures of the nozzle carrier are preferably substantially rectangular. However, it is alternatively also possible that the individual curvatures of the nozzle carrier each have a curvature angle of at least 70 ° or at least 80 °. In addition, it is possible that the individual curvatures of the nozzle carrier each have a Krüm- angle of at most 110 ° or at most 100 °.
Weiterhin ist zu erwähnen, dass der Düsenträger vorzugsweise in einer Ebene verläuft. Es ist jedoch in Abhängigkeit von der Bauteilgeometrie im Bereich des Spalts theoretisch auch möglich, dass die einzelnen Schenkel des Düsenträgers nicht in einer Ebene verlaufen.It should also be mentioned that the nozzle carrier preferably extends in one plane. However, depending on the component geometry in the region of the gap, it is theoretically also possible that the individual legs of the nozzle carrier do not run in one plane.
In einem bevorzugten Ausführungsbeispiel der Erfindung weist der Düsenträger vier Schenkel auf, die jeweils rechtwinklig zueinander angewinkelt sind und eine Doppel-L-Form bilden. Der distale Schenkel des Düsenträgers verläuft hierbei im Wesentlichen parallel zur Bauteilrückseite und appliziert das Beschichtungsmittel (z.B. Dichtmasse) vorzugsweise im Wesent- liehen rechtwinklig zu der Bauteilrückseite. An diesen distalen Schenkel grenzen zwei weitere Schenkel an, die durch den Spalt hindurch ragen und rechtwinklig zueinander angewinkelt sind. Schließlich ist ein proximaler Schenkel vorgesehen, der beispielsweise von einem Beschichtungsroboter positioniert wird.In a preferred embodiment of the invention, the nozzle carrier has four legs, each perpendicular are angled to each other and form a double-L shape. The distal leg of the nozzle carrier in this case runs essentially parallel to the component rear side and preferably applies the coating agent (for example, sealing compound) at a right angle to the component rear side. Adjacent to this distal limb are two further limbs which project through the gap and are bent at right angles to one another. Finally, a proximal limb is provided which is positioned, for example, by a coating robot.
Es wurde bereits vorstehend erwähnt, dass der Düsenträger vorzugsweise ein hohles Zuleitungsrohr ist, durch welches das Beschichtungsmittel zu der Düse geleitet wird. Die Erfindung beansprucht jedoch auch Schutz für eine alternative Ausführungsform, bei welcher der Düsenträger lediglich eine mechanische Funktion hat und nicht zur Durchleitung des Beschich- tungsmittels dient, wobei das Beschichtungsmittel dann beispielsweise durch eine in den Düsenträger eingelassene Schlauchleitung zu der Düse fließen kann.It has already been mentioned above that the nozzle carrier is preferably a hollow feed tube through which the coating agent is conducted to the nozzle. However, the invention also claims protection for an alternative embodiment, in which the nozzle carrier has only a mechanical function and does not serve for the passage of the coating agent, wherein the coating agent can then flow to the nozzle, for example, by a hose inserted into the nozzle carrier.
Weiterhin ist zu erwähnen, dass der Düsenträger vorzugsweise aus einem Material besteht, das elastisch ist und/oder ein Formgedächtnis aufweist. Dies bietet den Vorteil, dass der Düsenträger nach einer Kollision mit den zu beschichtendenIt should also be mentioned that the nozzle carrier preferably consists of a material which is elastic and / or has a shape memory. This offers the advantage that the nozzle carrier after a collision with the to be coated
Bauteilen wieder seine ursprüngliche und konstruktiv vorgegebene Form einnimmt, was für eine hochpräzise Positionierung der Düse erforderlich ist. Beispielsweise kann es sich bei dem Material mit einem Formgedächtnis um eine Nickel-Titan- Legierung handeln, wie beispielsweise TitanFlex®.Components again assumes its original and constructive predetermined form, which is required for a high-precision positioning of the nozzle. For example, it may be the material having a shape memory is a nickel-titanium alloy, such as titanium Flex ®.
Ferner besteht im Rahmen der Erfindung die Möglichkeit, dass der Applikator mindestens eine zusätzliche weitere Düse aufweist, wie beispielsweise eine Flatstream-Düse, eine Rund- strahl-Düse, eine Airless-Düse oder eine weitere Düse zur Bördelnahtabdichtung. Dies ermöglicht einen Kombinationsbetrieb, bei dem mit demselben Applikator abwechselnd Bördelnähte abgedichtet werden und sonstige Beschichtungen vorge- nommen werden bzw. sonstiges Beschichtungsmittel appliziert wird.Furthermore, within the scope of the invention, the possibility exists that the applicator has at least one additional additional nozzle, such as, for example, a flat-stream nozzle, a round nozzle. jet nozzle, an airless nozzle or another flare seam sealing nozzle. This makes possible a combination operation in which flanging seams are alternately sealed with the same applicator and other coatings are carried out or other coating agent is applied.
Darüber hinaus umfasst die Erfindung nicht nur den vorstehend beschriebenen erfindungsgemäßen Applikator als einzelnes Bau- teil, sondern auch eine Beschichtungsanlage zur Bördelnahtabdichtung an Kraftfahrzeug-Karosseriebauteilen mit einem solchen Applikator.In addition, the invention comprises not only the applicator according to the invention described above as a single component, but also a coating system for flanged seam sealing on motor vehicle body components with such an applicator.
Bei einer derartigen Beschichtungsanlage ist vorzugsweise ei- ne Vermessungseinrichtung vorgesehen, welche die Geometrie des Applikators und insbesondere des Düsenträgers vermisst, um zu überprüfen, ob der Düsenträger noch die konstruktionsbedingt vorgegebene Form hat oder aufgrund einer Kollision mit den zu beschichtenden Bauteilen zwischenzeitlich verformt wurde. Eine derartige Vermessungseinrichtung kann beispielsweise eine Lichtschranke aufweisen, welche die Außenkontur des Applikators und insbesondere des Düsenträgers erfasst.In such a coating system, a measuring device is preferably provided which measures the geometry of the applicator and in particular of the nozzle carrier in order to check whether the nozzle carrier still has the design-dictated shape or has been deformed due to a collision with the components to be coated. Such a measuring device may for example have a light barrier, which detects the outer contour of the applicator and in particular of the nozzle carrier.
Ferner weist die erfindungsgemäße Beschichtungsanlage vor- zugsweise eine Reinigungsvorrichtung auf, um den Applikator bzw. die Düse abzublasen und von eventuell anhaftendem Be- schichtungsmaterial zu reinigen und/oder mit einem Spülmittel zu spülen, wobei derartige Reinigungsvorrichtungen aus dem Stand der Technik bekannt sind und deshalb nicht näher be- schrieben werden müssen.Furthermore, the coating installation according to the invention preferably has a cleaning device in order to blow off the applicator or the nozzle and to clean it of any adhering coating material and / or to rinse it with a rinsing agent, such cleaning devices being known from the prior art and therefore need not be described in detail.
Hierbei ist es vorteilhaft, wenn die Vermessungseinrichtung zur Vermessung der Geometrie des Applikators in die Reinigungsvorrichtung baulich integriert wird. Zum Einen wird da- durch Bauraum gespart. Zum Anderen kann die Geometrie des Applikators auf diese Weise während des Reinigens vermessen werden, wodurch Taktzeit gespart wird.It is advantageous if the measuring device for measuring the geometry of the applicator is structurally integrated into the cleaning device. On the one hand, Saved by space. On the other hand, the geometry of the applicator can be measured in this way during cleaning, whereby cycle time is saved.
Ferner kann auch der erfindungsgemäße Applikator zwischen dem Düsenträger und dem zur Befestigung an dem Roboter dienenden Anschlussflansch ein Gelenk aufweisen, das eine Ausweichbewegung des Düsenträgers relativ zu dem Anschlussflansch ermöglicht. Dies bietet den Vorteil, dass eine Kollision zwischen dem Applikator und den zu beschichtenden Bauteilen nicht sofort zu einer Beschädigung des Applikators führt, da der Düsenträger aufgrund des Gelenks nachgeben kann. Ein derartiges Gelenk ist in dem bereits eingangs erwähnten Patent DE 10 2007 037 865 B3 beschrieben, so dass der Inhalt dieses Pa- tents der vorliegenden Beschreibung in vollem Umfang zuzurechnen ist.Furthermore, the applicator according to the invention can also have a joint between the nozzle carrier and the connecting flange serving for attachment to the robot, which allows a deflection movement of the nozzle carrier relative to the connecting flange. This offers the advantage that a collision between the applicator and the components to be coated does not immediately lead to damage to the applicator, since the nozzle carrier can give way due to the joint. Such a joint is described in the already mentioned patent DE 10 2007 037 865 B3, so that the content of this patent is to be fully attributed to the present description.
Schließlich umfasst die Erfindung auch ein Betriebsverfahren für einen Applikator, wobei sich das Betriebsverfahren da- durch auszeichnet, dass der Applikator durch einen Spalt zwischen zwei benachbarten, einander überlappenden Bauteilen hindurch von der Vorderseite auf die Rückseite der benachbarten Bauteile ragt, um auf der Rückseite der Bauteile Be- schichtungsmittel zu applizieren.Finally, the invention also includes an operating method for an applicator, wherein the operating method is characterized in that the applicator protrudes through a gap between two adjacent overlapping components from the front side to the rear side of the adjacent components in order to secure the back side of the adjacent components Apply components to coating agents.
Hierbei wird der Applikator vorzugsweise entlang dem Spalt bewegt, um eine langgestreckte Bahn der Dichtmasse auf die Bördelnaht zu applizieren.In this case, the applicator is preferably moved along the gap in order to apply an elongate path of the sealant to the hemming seam.
Wichtig ist hierbei, dass das Einführen des Applikators durch den Spalt und die Applikation des Beschichtungsmittels möglich ist, während die Kraftfahrzeugtür geschlossen ist. Andere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet oder werden nachstehend zusammen mit der Beschreibung der bevorzugten Ausführungsbeispiele der Erfindung anhand der Figuren näher erläutert. Es zeigen:It is important here that the insertion of the applicator through the gap and the application of the coating agent is possible while the vehicle door is closed. Other advantageous developments of the invention are characterized in the subclaims or are explained in more detail below together with the description of the preferred embodiments of the invention with reference to FIGS.

Figur 1 zeigt den Bereich eines Spalts 1 zwischen einer Kraftfahrzeugtür 2 und einem Kotflügel 3, wobei die Kraftfahrzeugtür 2 in dem in der Zeichnung dargestellten geschlossenen Zustand mit dem Kotflügel 3 überlappt, um die Crash- Sicherheit zu verbessern. Die Kraftfahrzeugtür 2 weist ein Innenblech 4 und eine Blechbeplankung 5, wobei die Blechbeplankung 5 um eine angewinkelte Kante des Innenblechs 4 herumgebördelt ist. Im Bereich der angewinkelten Kante ist das Innenblech 4 durch eine Klebe- Schicht 6 mit der Blechbeplankung 5 verbunden. Bei diesem Aufbau besteht die Gefahr, dass im Bereich der Bördelnaht Feuchtigkeit in den Spalt zwischen der angewinkelten Kante des Innenblechs 4 und der herumgebördelten Kante der Blechbeplankung 5 eintritt und Korrosion verursacht. Die Bördelnaht zwischen dem Innenblech 4 und der Blechbeplankung 5 ist deshalb mit einer Dichtmasse 7 versiegelt, um das Eindringen von Feuchtigkeit in die Bördelnaht zu verhindern, wobei sich die Dichtmasse 7 rechtwinklig zur Zeichenebene über die gesamte Länge der Bördelnaht erstreckt. Die Applikation der Dichtmas- se 7 erfolgt hierbei durch einen erfindungsgemäßen Applikator 8, der durch den Spalt 1 zwischen der Kraftfahrzeugtür 2 und dem Kotflügel 3 hindurch ragt, wie noch detailliert erläutert wird.Figure 1 shows the region of a gap 1 between a motor vehicle door 2 and a fender 3, wherein the motor vehicle door 2 overlaps with the fender 3 in the closed state shown in the drawing in order to improve the crash safety. The motor vehicle door 2 has an inner panel 4 and a sheet metal panel 5, wherein the sheet metal panel 5 is herumgebördelt around an angled edge of the inner panel 4. In the region of the angled edge, the inner panel 4 is connected by an adhesive layer 6 with the Blechbeplankung 5. In this structure, there is a risk that in the region of the flanged seam moisture enters the gap between the angled edge of the inner panel 4 and the flanged edge of the sheet metal panel 5 and causes corrosion. The flanged seam between the inner panel 4 and the Blechbeplankung 5 is therefore sealed with a sealant 7 to prevent the ingress of moisture into the flanged seam, wherein the sealant 7 extends at right angles to the plane over the entire length of the flanged seam. The application of the sealing compound 7 takes place here by an applicator 8 according to the invention, which protrudes through the gap 1 between the motor vehicle door 2 and the mudguard 3, as will be explained in detail.
Der erfindungsgemäße Applikator wird von einem mehrachsigenThe applicator according to the invention is of a multi-axis
Roboter positioniert und weist zur Montage an dem Roboter einen Anschlussflansch 9 auf, wobei der Roboter zur Vereinfachung nicht dargestellt ist.Robot positioned and has for mounting to the robot on a connecting flange 9, wherein the robot is not shown for simplicity.
An dem Anschlussflansch 9 des Applikators 8 ist ein rohrför- miger Düsenträger 10 montiert. Zum einen dient der Düsenträger 10 zur mechanischen Führung einer Düse 11, die an dem distalen Ende des Düsenträgers 10 angeordnet ist. Zum anderen dient der Düsenträger 10 zur Durchleitung der Dichtmasse von dem Anschlussflansch 9 zu der Düse 11, wozu der Düsenträger 10 hohl ausgeführt ist.At the connecting flange 9 of the applicator 8 a rohrför- miger nozzle carrier 10 is mounted. On the one hand, the nozzle carrier 10 serves for the mechanical guidance of a nozzle 11, which is arranged at the distal end of the nozzle carrier 10. On the other hand, the nozzle carrier 10 serves to pass the sealing compound from the connection flange 9 to the nozzle 11, for which purpose the nozzle carrier 10 is made hollow.
Der Düsenträger 10 weist vier Schenkel 12, 13, 14, 15 auf, die jeweils rechtwinklig zueinander angeordnet sind, wobei die distalen Schenkel 12, 13, 14 des Düsenträgers 10 einen U- förmigen Abschnitt bilden, der die angewinkelte Kante des Innenblechs 5 mit der Bördelnaht umgreifen. Die dargestellte Geometrie des Applikators 8 ermöglicht es, dass die Düse 11 durch den Spalt 1 zwischen der Kraftfahrzeugtür 2 und demThe nozzle carrier 10 has four legs 12, 13, 14, 15, which are each arranged at right angles to each other, wherein the distal legs 12, 13, 14 of the nozzle carrier 10 form a U-shaped section, which surround the angled edge of the inner panel 5 with the flanged seam. The illustrated geometry of the applicator 8 allows the nozzle 11 through the gap 1 between the motor vehicle door 2 and the
Kotflügel 3 hindurch auf die Rückseite der Kraftfahrzeugtür 2 und des Kotflügels 3 ragt, um die Dichtmasse 7 auf die dort befindliche Bördelnaht zu applizieren. Hierbei ist es nicht erforderlich, dass die Kraftfahrzeugtür 2 zuvor geöffnet wird, so dass auf einen Handhabungsroboter zum Öffnen der Kraftfahrzeugtür 2 verzichtet werden kann.Mudguard 3 passes through on the back of the vehicle door 2 and the fender 3 projects to apply the sealant 7 to the flaring seam located there. In this case, it is not necessary for the motor vehicle door 2 to be opened beforehand, so that a handling robot for opening the motor vehicle door 2 can be dispensed with.
Figur 2 zeigt eine Seitenansicht einer Kraftfahrzeugkarosserie 16 mit mehreren Bördelnähten 17, 18, 19, 20, 21, die mit dem in Figur 1 dargestellten Applikator 8 mit der Dichtmasse 7 abgedichtet werden können.FIG. 2 shows a side view of a motor vehicle body 16 with a plurality of flanged seams 17, 18, 19, 20, 21 which can be sealed with the sealing compound 7 with the applicator 8 shown in FIG.
Figur 3 zeigt ein bevorzugtes Ausführungsbeispiel des erfindungsgemäßen Applikators 8, das sich von dem Ausführungsbei- spiel gemäß Figur 1 geringfügig unterscheidet.FIG. 3 shows a preferred exemplary embodiment of the applicator 8 according to the invention, which differs slightly from the exemplary embodiment according to FIG.
So weist der Schenkel 14 des Düsenträgers 10 gegenüber dem Schenkel 15 des Düsenträgers 10 einen Krümmungswinkel α«80° auf .Thus, the leg 14 of the nozzle carrier 10 with respect to the leg 15 of the nozzle carrier 10 has a curvature angle α «80 °.
Der Schenkel 13 weist dagegen gegenüber dem Schenkel 14 des Düsenträgers 10 einen Krümmungswinkel ß«80° auf.By contrast, the leg 13 has a curvature angle .beta. <80.degree. Relative to the leg 14 of the nozzle carrier 10.
Schließlich weist der Schenkel 12 des Düsenträgers 10 gegen- über dem Schenkel 13 einen Krümmungswinkel χ=90° auf, wie es auch bei dem Ausführungsbeispiel gemäß Figur 1 der Fall ist. Figur 4 zeigt ein abgewandeltes Ausführungsbeispiel, das weitgehend mit dem Ausführungsbeispiel gemäß Figur 1 übereinstimmt, wobei die Krümmungswinkel α=ß=χ=90° betragen.Finally, the leg 12 of the nozzle carrier 10 has a curvature angle χ = 90 ° relative to the leg 13, as is also the case in the exemplary embodiment according to FIG. FIG. 4 shows a modified exemplary embodiment, which largely corresponds to the exemplary embodiment according to FIG. 1, wherein the angles of curvature α = β = χ = 90 °.
Schließlich zeigt Figur 5 eine Vermessungseinrichtung 17 zur Vermessung der Geometrie des Applikators 8. Hierzu weist die Vermessungseinrichtung 17 eine Lichtschranke 18 auf, welche die Außenkontur des Applikators 8 und insbesondere des Düsenträgers 10 abtastet. Die Vermessung der Geometrie des Appli- kators 8 ermöglicht vorteilhaft die Erkennung von Deformationen des Applikators 8, die beispielsweise von Kollisionen zwischen dem Applikator 8 und der Kraftfahrzeugtür 2 bzw. dem Kotflügel 3 herrühren können.Finally, FIG. 5 shows a measuring device 17 for measuring the geometry of the applicator 8. For this purpose, the measuring device 17 has a light barrier 18 which scans the outer contour of the applicator 8 and in particular of the nozzle carrier 10. The measurement of the geometry of the applicator 8 advantageously makes it possible to detect deformations of the applicator 8, which can result, for example, from collisions between the applicator 8 and the motor vehicle door 2 or the fender 3.
Hierbei ist zu erwähnen, dass die Vermessungseinrichtung 17 vorzugsweise in eine Reinigungsvorrichtung integriert werden kann, die dazu dient, den Applikator 8 durch Abblasen bzw. durch Spülen mit einem Spülmittel zu reinigen. Die Integration der Vermessungseinrichtung 17 in die Reinigungseinrichtung bietet den Vorteil, dass Bauraum und Taktzeit eingespart wird, da die Vermessung des Applikators 8 während der ohnehin erforderlichen Reinigung des Applikators 8 erfolgen kann.It should be mentioned here that the measuring device 17 can preferably be integrated into a cleaning device which serves to clean the applicator 8 by blowing off or by rinsing with a rinsing agent. The integration of the measuring device 17 in the cleaning device has the advantage that space and cycle time is saved, since the measurement of the applicator 8 during the already required cleaning of the applicator 8 can be done.
