Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Ultraschallsensors, mit einem Gehäuse, einer Membrane und einem zwischen dem Gehäuse und der Membrane angeordneten Entkopplungsmedium. Derartige Ultraschallsensoren finden beispielsweise bei Nahbereichserkennungssystemen von Kraftfahrzeugen Verwendung. Bei bekannten Ultraschallsensoren werden die einzeln hergestellten Bauteile durch Ineinanderstecken miteinander gefügt. Aufgrund der Bauteiltoleranzen unterliegt die Positionierung der Membrane gegenüber dem Gehäuse unerwünschten Toleranzschwankungen. The invention relates to a method for producing a Ultrasonic sensor, with a housing, a membrane and one arranged between the housing and the membrane Decoupling medium. Find such ultrasonic sensors for example with short-range detection systems from Motor vehicles use. At acquaintances Ultrasonic sensors are the individually manufactured Components joined together by plugging them together. Due to the component tolerances, the Position the membrane against the housing undesirable tolerance fluctuations.
Um ein genaues und funktionssicheres Arbeiten der Ultraschallsensoren zu gewährleisten, ist jedoch die exakte Positionierung der Membranen gegenüber dem Gehäuse von besonderer Wichtigkeit.To ensure that the Ensuring ultrasonic sensors is, however, the exact one Position the membranes in relation to the housing of of particular importance.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Ultraschallsensors bereitzustellen, bei welchem die unerwünschten Toleranzen möglichst gering und optimalerweise vollständig ausgeschlossen werden können.The present invention is therefore based on the object based on a method for producing a Provide ultrasonic sensor, in which the undesirable tolerances as small as possible and can optimally be completely excluded.
Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, das Entkopplungsmedium in einem verformbaren Zustand zwischen die Membrane und das Gehäuse zu geben. Dies hat den Vorteil, dass bei der Herstellung des Ultraschallsensors die Membrane gegenüber dem Gehäuse exakt vorpositioniert werden kann und dass durch Auffüllen des Zwischenraumes zwischen der Membrane und dem Gehäuse mit dem Entkopplungsmedium die Positionierung der Membrane gegenüber dem Gehäuse eingefroren wird. Somit wird erfindungsgemäß erreicht, dass bei der Herstellung bzw. der Montage des Ultraschallsensors die exakte Positionierung der Membrane gegenüber dem Gehäuse gewährleistet ist. Vorteilhafterweise härtet das Entkopplungsmedium, nachdem es zwischen die Membrane und das Gehäuse gegeben wurde, aus und positioniert damit dauerhaft die Membrane in dem Gehäuse. Sich addierende Toleranzen, die zu einer unexakten Positionierung der Membrane innerhalb des Gehäuses führen, wie sie aus dem bekannten Stand der Technik bekannt sind, werden erfindungsgemäß ausgeschlossen.To solve the problem, the invention proposes the decoupling medium in a deformable state between the membrane and the housing. this has the advantage that in the manufacture of the Ultrasonic sensor the membrane opposite the housing exactly can be prepositioned and that by filling the Space between the membrane and the housing with the decoupling medium the positioning of the membrane is frozen relative to the housing. Thus achieved according to the invention that in the manufacture or Mounting the ultrasonic sensor for exact positioning the membrane opposite the housing is guaranteed. The decoupling medium advantageously hardens after between the membrane and the housing and thus permanently positions the membrane in the Casing. Adding tolerances that lead to an inexact Position the membrane within the housing, as they are known from the known prior art, are excluded according to the invention.
Vorteilhafterweise kann erfindungsgemäß vorgesehen sein, dass das Entkopplungsmedium zwischen die Membrane und das Gehäuse gegossen wird. Es hat sich gezeigt, dass insbesondere das Spritzgießen des Entkopplungsmediums zwischen die Membrane und das Gehäuse zu einer besonders guten, dauerhaften und positionsgenauen Anordnung der Membrane innerhalb des Gehäuses führen kann. Das Entkopplungsmedium, das vorzugsweise gummiartige Eigenschaften aufweist, kann problemlos durch Spritzgießen verarbeitet werden.According to the invention, it can advantageously be provided that that the decoupling medium between the membrane and the Housing is cast. It has been shown that especially the injection molding of the decoupling medium between the membrane and the housing to a particular good, permanent and positionally accurate arrangement of the Membrane can lead inside the housing. The Decoupling medium, which is preferably rubbery Features can be easily injection molded are processed.
Bei einer weiteren, besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Membrane in einem ersten Arbeitsschritt mit einem das Gehäuse bildenden Kunststoff und in einem zweiten Arbeitsschritt mit dem zwischen dem Gehäuse und der Membrane liegenden Entkopplungsmedium umspritzt wird. Vorteilhafterweise können diese beiden Arbeitsschritte innerhalb einer Spritzanlage durchgeführt werden. Da das Gehäuse vorzugsweise aus einem harten oder festen Kunststoff ist, der nach dem Spritzvorgang relativ schnell aushärtet, wird vorzugsweise zuerst das Gehäuse gespritzt. Zwischen die Membrane, die vorzugsweise aus einem metallischen Werkstoff, insbesondere aus Aluminium, ist, und das Gehäuse wird dann das vorzugsweise gummiartige Entkopplungsmedium eingespritzt.In a further, particularly preferred embodiment the invention provides that the membrane in one first step with a housing Plastic and in a second step with the between the housing and the membrane Decoupling medium is encapsulated. advantageously, can do these two steps within one Spraying system can be carried out. Because the housing is preferably made of a hard or solid plastic, which hardens relatively quickly after the spraying process preferably injection molded the housing first. Between the Membrane, preferably made of a metallic Material, in particular aluminum, and the housing then becomes the preferably rubber-like decoupling medium injected.
Erfindungsgemäß finden die beiden genannten Arbeitsschritte nacheinander innerhalb einer 2-Komponenten-Spritzanlage statt. Dies hat den Vorteil, dass mit sehr wenigen Arbeitsschritten die Herstellung bzw. Montage des Gehäuses, der Membrane und des Entkopplungsmediums erfolgt.According to the two steps mentioned one after the other within a 2-component spraying system instead of. This has the advantage that with very few Work steps the manufacture or assembly of the housing, the membrane and the decoupling medium.
Grundsätzlich erfolgt die Umspritzung derart, dass sie die mechanischen Schwingungen der Membrane gegenüber dem Gehäuse bzw. der Umgebung des Gehäuses über einen vorgegebenen Temperaturbereich definiert entkoppelt, dass sie eine genügend große mechanische Stabilität besitzt und dass sie das Einbringen von Medien aller Art in das Innere der Membrane verhindert.In principle, the extrusion coating is carried out in such a way that it mechanical vibrations of the membrane compared to the Housing or the environment of the housing over a predetermined temperature range defines decouples that it has a sufficiently high mechanical stability and that they are bringing all kinds of media inside prevents the membrane.
Die eingangs genannte Aufgabe wird auch durch einen Ultraschallsensor gelöst, der nach einem der vorhergehenden Ansprüche hergestellt ist.The task mentioned at the outset is also achieved by a Ultrasonic sensor solved, according to one of the preceding Claims is made.
