Description
Die Erfindung bezieht sich auf ein Verfahren zum Aufkle ben eines Bauteiles auf eine Fläche, insbesondere eines Regensensors auf eine Windschutzscheibe. Weiterhin be trifft die Erfindung einen nach diesem Verfahren aufzu klebenden Sensor.The invention relates to a method for sticking ben of a component on a surface, in particular one Rain sensor on a windshield. Continue to be the invention applies to one according to this method adhesive sensor.
Zum Aufkleben eines Bauteiles auf eine Fläche kann man das Bauteil und/oder die Fläche mittels eines Pinsels mit Klebstoff versehen und dann das Bauteil gegen die Fläche drücken. Diese Verfahrensweise ist relativ zeit aufwendig und führt häufig dazu, daß nach dem Aufdrücken des Bauteiles Klebstoff an seinen Seiten hervorquillt, was häßlich aussieht. You can glue a component to a surface the component and / or the surface by means of a brush provided with adhesive and then the component against the Press surface. This procedure is relatively time-consuming expensive and often leads to the fact that after pressing the component's adhesive swells out on its sides, what looks ugly.
Bekannt ist es auch, aufzuklebende Bauteile mit einer beidseitig klebenden Klebefolie zu versehen. Dadurch wird das Aufkleben erleichtert und das Hervorquellen von Klebstoff vermieden. Nachteilig bei dieser Verfahrens weise ist oftmals jedoch, daß sich Luftblaseneinschlüsse praktisch nicht vermeiden lassen. Solche Lufteinschlüsse können beispielsweise bei einem innenseitig gegen die Windschutzscheibe zu klebenden Regensensor das Sensor signal verfälschen. Weiterhin erscheinen Luftblasen auf insbesondere schwarzem Hintergrund optisch störend.It is also known to glue components with a to provide double-sided adhesive film. Thereby the sticking is made easier and the swelling of Avoided glue. A disadvantage of this method It is often wise, however, that there are bubbles practically cannot be avoided. Such air pockets can for example with an inside against the Windshield-to-stick rain sensor the sensor distort signal. Air bubbles continue to appear especially black background optically disturbing.
Der Erfindung liegt das Problem zugrunde, ein Verfahren zum Aufkleben eines Bauteiles auf eine Fläche, insbeson dere eines Regensensors auf eine Windschutzscheibe, zu entwickeln, welches sehr rasch und einfach ausführbar ist, Lufteinschlüsse in der Klebefläche jedoch aus schließt. Weiterhin soll ein nach diesem Verfahren auf zuklebender Sensor geschaffen werden.The problem underlying the invention is a method for gluing a component onto a surface, in particular of a rain sensor on a windshield develop which can be carried out very quickly and easily air pockets in the adhesive surface closes. Furthermore, one should follow this procedure adhesive sensor can be created.
Das erstgenannte Problem wird erfindungsgemäß dadurch gelöst, daß zwischen dem Bauteil und der Fläche ein mit einem flüssigen Klebstoff gefüllter, bei Druckbeanspru chung zerplatzender Hohlkörper eingefügt wird.According to the invention, the first-mentioned problem is thereby solved solved that between the component and the surface with a filled with a liquid adhesive, under pressure bursting hollow body is inserted.
Durch diese Verfahrensweise läßt sich eine gleich gute und Lufteinschlüsse ausschließende Klebverbindung er zielen, wie wenn man die Klebefläche mit einem Pinsel mit Klebstoff bestreichen würde. Das erfindungsgemäße Verfahren ist jedoch wesentlich rascher durchzuführen. Da der Hohlkörper mit dem flüssigen Klebstoff der Größe der Klebefläche entsprechend bemessen sein kann, ist es leicht möglich, durch die richtige Festlegung der Kleb stoffmenge ein Hervorquellen von Klebstoff zu vermeiden. Denkbar wäre es natürlich auch, statt eines Hohlkörpers mehrere davon zu verwenden, um für eine größere Klebe fläche die richtige Klebstoffmenge zu erhalten. Vorteil haft ist bei dem erfindungsgemäßen Verfahren auch, daß der Klebstoff in den Hohlkörpern problemlos gasdicht ge lagert werden kann. Für den Klebevorgang wird immer nur die gerade benötigte Klebstoffmenge der Einwirkung von Luft ausgesetzt. Ein Eintrocknen von Klebstoffspendern ist dadurch ausgeschlossen. Weiterhin brauchen keine Ge räte zum Verteilen des Klebstoffes benutzt und nach Ge brauch gereinigt zu werden.This procedure allows an equally good one and adhesive connection to exclude air pockets aim like looking at the adhesive surface with a brush would spread with glue. The invention However, the procedure can be carried out much more quickly. Because the hollow body with the liquid adhesive of the size the adhesive surface can be dimensioned accordingly, it is easily possible by correctly setting the glue to prevent the adhesive from swelling. It would of course also be conceivable instead of a hollow body use several of them for a larger glue to get the right amount of adhesive. Advantage is also in the inventive method that the adhesive in the hollow bodies is easily gastight can be stored. For the gluing process is always only the amount of adhesive just required to be affected by Exposed to air. A drying of adhesive dispensers is excluded. Furthermore, no ge used to distribute the adhesive and according to Ge need to be cleaned.
Das zweitgenannte Problem wird erfindungsgemäß dadurch gelöst, daß der Klebstoff als Flüssigkeit in einem bei Druckbeanspruchung zerplatzenden Hohlkörper angeordnet ist.The second-mentioned problem is thereby inventively solved that the adhesive as a liquid in one Compressed hollow body bursting arranged is.
Ein solcher Sensor kann einfach gegen die Fläche ge drückt werden, auf die er geklebt werden soll. Dabei zerplatzt der den flüssigen Klebstoff enthaltende Hohl körper, so daß der Klebstoff sich durch Kapillarwirkung ausbreiten und die Klebung erfolgen kann. Deshalb ist die Klebeverbindung äußerst einfach und unter Ausschluß von Lufteinschlüssen zuverlässig zu bewerkstelligen.Such a sensor can simply be against the surface be pressed onto which it is to be glued. Here the hollow containing the liquid adhesive bursts body, so that the adhesive is separated by capillary action spread out and the gluing can take place. Therefore the adhesive connection extremely simple and to the exclusion of air inclusions to be reliably accomplished.
Die Handhabung des aufzuklebenden Sensors mit dem den flüssigen Klebstoff enthaltenden Hohlkörper ist beson ders einfach, wenn der Sensor eine Vertiefung zur teil weisen Aufnahme des Hohlkörpers hat und der in diese Vertiefung eingelegte Hohlkörper geringfügig über die Kontur der die Vertiefung aufweisende Klebefläche ragt. Diese Vertiefung stellt sicher, daß der Hohlkörper sich zwangsläufig an der richtigen Stelle befindet und des halb nach seinem Zerplatzen eine gleichmäßige Klebstoff verteilung erfolgt.The handling of the sensor to be glued with the hollow body containing liquid adhesive is special it’s easy if the sensor partially deepens have recording of the hollow body and in this Hollow body inserted slightly above the Contour that protrudes the adhesive surface having the recess. This depression ensures that the hollow body itself inevitably in the right place and the half after it bursts an even glue distribution takes place.
Das Zerplatzen des Hohlkörpers kann ohne unerwünscht große Druckkräfte durch einen Kerbvorgang eingeleitet werden, wenn gemäß einer anderen Ausgestaltung der Er findung im Sensor ein bei Druckbeanspruchung gegen den Hohlkörper beweglicher Dorn angeordnet ist. The bursting of the hollow body can be undesirable large pressure forces initiated by a notching process be, if according to another embodiment of the Er in the sensor when there is pressure against the Hollow body movable mandrel is arranged.
Besonders vorteilhaft ist es, wenn die Klebefläche kreis förmig und der Hohlkörper kugelförmig sind. Falls die Klebefläche länglich ist, könnte man natürlich auch für den Klebstoff einen zylindrischen Hohlkörper vorsehen. Denkbar ist es auch, bei einer unregelmäßigen Klebeflä che den Hohlkörper entsprechend zu formen.It is particularly advantageous if the adhesive surface is circular shaped and the hollow body are spherical. if the Adhesive surface is elongated, one could of course also for provide the adhesive with a cylindrical hollow body. It is also conceivable for an irregular adhesive surface che shape the hollow body accordingly.
Wichtig ist, daß der Hohlkörper beim Andrückvorgang leicht zerplatzt. Sein Werkstoff muß deshalb spröde sein. Er könnte beispielsweise aus Kunststoff bestehen. Besonders vorteilhaft ist es jedoch, wenn der Hohlkörper aus Glas besteht.It is important that the hollow body during the pressing process easily burst. Its material must therefore be brittle be. For example, it could be made of plastic. However, it is particularly advantageous if the hollow body is made of glass.
Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist in der Zeichnung schematisch ein Sensor mit Abstand zu einer Windschutzscheibe dargestellt und wird nachfolgend be schrieben.The invention permits numerous embodiments. To further clarification of their basic principle is in the Drawing schematically a sensor at a distance from one Windshield shown and will be below wrote.
Die Zeichnung zeigt eine Windschutzscheibe 1, welche eine fahrzeuginnenseitige Fläche 2 hat, auf die ein als Regensensor ausgebildeter Sensor 3 mit einer kreisförmi gen Klebefläche 4 aufgeklebt werden soll. In der Klebe fläche 4 ist eine kugelkalottenförmige Vertiefung 5 vor gesehen, in welche ein kugelförmiger Hohlkörper 6 aus beispielsweise Glas eingesetzt ist, der flüssigen Kleb stoff 7 enthält. Oberhalb der Vertiefung 5 kann im Sen sor 3 ein Dorn 8 vorgesehen sein, der bei Druck auf den Sensor 3 in Richtung des Pfeiles 9 gegen den Hohlkörper 6 gelangt und ihn kerbt.The drawing shows a windshield 1 , which has a vehicle-side surface 2 to which a sensor 3 designed as a rain sensor is to be glued with a circular adhesive surface 4 . In the adhesive surface 4 , a spherical cap-shaped recess 5 is seen before, in which a spherical hollow body 6 made of, for example, glass is used, which contains liquid adhesive material 7 . Above the recess 5 may be provided in the sen sor 3, a mandrel 8 which comes in pressure on the sensor 3 in the direction of the arrow 9 against the hollow body 6 and it slots.
Zum Aufkleben des Sensors 3 auf die Fläche 2 braucht man den Sensor 3 mit dem in seine Vertiefung 5 eingesetzten Hohlkörper 6 lediglich gegen die Fläche 2 zu drücken. Der Hohlkörper 6 zerplatzt dann, so daß sich der in ihm enthaltene, für die Klebstofffläche 4 bemessene Kleb stoff auf die Klebstofffläche verteilt, ohne seitlich hervorzuquellen.To glue the sensor 3 onto the surface 2 , one only needs to press the sensor 3 with the hollow body 6 inserted into its recess 5 against the surface 2 . The hollow body 6 then bursts, so that the adhesive contained in it, dimensioned for the adhesive surface 4, adhesive is distributed over the adhesive surface without swelling laterally.
