Description
Die vorliegende Erfindung betrifft ein Verfahren zum Anordnen einer Membran an einem Fügewerkzeug einer Werkzeugvorrichtung und eine Werkzeugvorrichtung, insbesondere ein Verfahren zum Anordnen einer Membran an einem Ultraschallschweißwerkzeug, das dazu ausgebildet ist, die Membran an einem Gehäuse dauerhaft anzubringen.The present invention relates to a method for arranging a membrane on a joining tool of a tool device and a tool device, in particular a method for arranging a membrane on an ultrasonic welding tool, which is adapted to permanently attach the membrane to a housing.
Membranen, die vorzugsweise semipermeabel sind, können beispielsweise an Gehäusen angebracht werden, um einen Druckausgleich zwischen dem Gehäuseinneren und dem Gehäuseäußeren. Beispielsweise werden solche semipermeablen Membranen an Kunststoffgehäusen von Sensoren, wie z. B. Luftmassenmesser, angebracht, um einen Druckausgleich zwischen dem Gehäuseinneren, in dem die Elektronik des Luftmassensensors angeordnet ist, und dem Gehäuseäußeren bereitzustellen und gleichzeitig in der Luft befindlichen Schmutz davon abzuhalten, in das Gehäuseinnere zu gelangen. Ferner können solche Membranen dazu verwendet werden, eine Öffnung in einem Gehäuse wasserdicht zu verschließen.Membranes, which are preferably semipermeable, may be attached to housings, for example, to provide pressure equalization between the interior of the housing and the exterior of the housing. For example, such semipermeable membranes on plastic housings of sensors such. As air mass meter, mounted to provide a pressure equalization between the housing interior, in which the electronics of the air mass sensor is arranged, and the housing exterior and at the same time to prevent airborne dirt from entering the housing interior. Furthermore, such membranes can be used to seal an opening in a housing watertight.
Das Anbringen solcher Membranen an dem Gehäuse erfolgt durch bekannte Fügeverfahren, wie beispielsweise Schweißen, Löten oder Kleben. Dazu wird eine bereits vorgefertigte Membran an einem entsprechenden Fügewerkzeug angeordnet und daraufhin an der gewünschten Position an dem Gehäuse dauerhaft angebracht. Das Herstellen der Membran erfolgt dabei bevorzugt aus einem plattenförmigen Körper. Beispielsweise kann auf dem plattenförmigen Körper eine Membran mittels eines Trennverfahrens herausgetrennt werde, beispielsweise mittels Ausschneiden, Ausstanzen oder Ausreißen.The attachment of such membranes to the housing is carried out by known joining methods, such as welding, soldering or gluing. For this purpose, an already prefabricated membrane is arranged on a corresponding joining tool and then permanently attached to the housing at the desired position. The membrane is preferably produced from a plate-shaped body. For example, on the plate-shaped body, a membrane can be cut out by means of a separation process, for example by means of cutting, punching or tearing.
Hierzu ist es beispielsweise bekannt, eine sogenannte Sonotrode, die ein bekanntes Ultraschallschweißwerkzeug ist, gleichzeitig als Stanzwerkzeug zu verwenden, mittels dem aus dem plattenförmigen Körper zumindest eine Membran durch einen Stanzprozess ausgestanzt werden kann. Nach dem Ausstanzen der Membran wird die Membran an der Sonotrode gehalten, um im direkten Anschluss die Membran an dem Gehäuse dauerhaft mittels Ultraschallschweißen anzubringen.For this purpose, it is known, for example, to use a so-called sonotrode, which is a known ultrasonic welding tool, simultaneously as a punching tool, by means of which at least one membrane can be punched out of the plate-shaped body by a stamping process. After punching out the membrane, the membrane is held on the sonotrode to permanently attach the membrane to the housing by means of ultrasonic welding in the direct connection.
Das aus dem Stand der Technik bekannten Verfahren, bei dem die Sonotrode die Doppelfunktion des Heraustrennens und Fügens umfasst, kann jedoch im Hinblick auf Verschleiß der Sonotrode während des Trennprozesses und daraus resultierend auf die Genauigkeit des Fügens verbesserungsbedürftig sein.However, the method known from the prior art in which the sonotrode has the double function of separating out and joining can be in need of improvement with regard to wear of the sonotrode during the cutting process and, as a result, to the accuracy of the joining.
Der vorliegenden Erfindung liegt folglich die Aufgabe zugrunde, ein Verfahren zum Anordnen einer Membran an einem Fügewerkzeug einer Werkzeugvorrichtung und eine Werkzeugvorrichtung bereitzustellen, das gegenüber dem bekannten Verfahren und den Werkzeugvorrichtungen zumindest teilweise verbessert ist.The present invention is therefore based on the object to provide a method for arranging a membrane on a joining tool of a tool device and a tool device, which is at least partially improved compared to the known method and the tool devices.
Diese Aufgabe wird mit einem Verfahren gemäß unabhängigem Anspruch 1 und einer Werkzeugvorrichtung gemäß unabhängigem Anspruch 8 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.This object is achieved by a method according to
Der vorliegenden Erfindung liegt im Wesentlichen der Gedanke zugrunde, ein separates Trennwerkzeug, wie beispielsweise ein Stanzwerkzeug, zu verwenden, das dazu ausgebildet ist, aus einem plattenförmigen Körper zumindest eine Membran herauszutrennen und gleichzeitig nach dem Trennvorgang die herausgetrennte Membran direkt an ein Fügewerkzeug, wie beispielsweise ein Ultraschallwerkzeug, zu transferieren. Das Transferieren umfasst dabei ein Transportieren der herausgetrennten Membran entlang einer geradlinigen Bewegungsbahn mittels des Trennwerkzeugs sowie ein Übergeben der herausgetrennten Membran vom Trennwerkzeug an das Fügewerkzeug.The present invention is based essentially on the idea to use a separate cutting tool, such as a punch, which is adapted to separate from a plate-shaped body at least one membrane and at the same time after the separation process, the separated membrane directly to a joining tool, such as an ultrasonic tool to transfer. In this case, the transfer comprises transporting the separated-out membrane along a rectilinear trajectory by means of the severing tool, and also transferring the severed membrane from the severing tool to the joining tool.
Bei dem erfindungsgemäßen Verfahren ist folglich keine Transfervorrichtung, wie beispielsweise Transferwerkzeuge und Transferroboter, vorgesehen, da das Transferieren der herausgetrennten Membran vom Trennwerkzeug nach dem Heraustrennen der Membran ausgeführt wird. Somit kann ein im Hinblick auf die Verfahrensdauer optimiertes Verfahren bereitgestellt werden, das zusätzlich kostengünstig ist.In the method according to the invention, therefore, no transfer device, such as transfer tools and transfer robots, is provided, since the transfer of the separated-out membrane from the cutting tool is carried out after the separation of the membrane. Thus, a method optimized in terms of process duration can be provided, which is additionally inexpensive.
Gemäß eines ersten Aspekts der vorliegenden Erfindung ist ein Verfahren zum Anordnen einer Membran an einem Fügewerkzeug einer Werkzeugvorrichtung vorgesehen. Das Fügewerkzeug ist dazu ausgebildet, die Membran an einem Gehäuse dauerhaft anzubringen. Das erfindungsgemäße Verfahren umfasst ein Bereitstellen eines plattenförmigen Körpers, aus dem zumindest eine Membran heraustrennbar ist, ein Zuführen des plattenförmigen Körpers in die Werkzeugvorrichtung, die das Fügewerkzeug und ein davon beabstandet angeordnetes Trennwerkzeug aufweist, das dazu ausgebildet ist, während eines Trennprozesses zumindest eine Membran aus dem plattenförmigen Körper herauszutrennen, ein Heraustrennen von zumindest einer Membran aus dem plattenförmigen Körper mittels des Trennwerkzeugs, ein Halten der zumindest einen herausgetrennten Membran durch das Trennwerkzeug und ein Transferieren der zumindest einen Membran an das Fügewerkzeug mittels des Trennwerkzeugs.According to a first aspect of the present invention, a method for arranging a membrane on a joining tool of a tool device is provided. The joining tool is designed to permanently attach the membrane to a housing. The method according to the invention comprises providing a plate-shaped body, from which at least one membrane is detachable, feeding the plate-shaped body into the tool device, which has the joining tool and a separating tool arranged spaced therefrom, which is designed to expose at least one membrane during a separation process separating out the plate-shaped body, separating out at least one membrane from the plate-shaped body by means of the separating tool, holding the at least one separated-out membrane by the separating tool and transferring the at least one membrane to the joining tool by means of the separating tool.
Dadurch, dass das Trennwerkzeug sowohl zum Heraustrennen der zumindest einen Membran als auch zum Transferieren der zumindest einen Membran an das Fügewerkzeug ausgebildet ist, kann auf eine separate Transfervorrichtung, wie beispielsweise einen Transferroboter, verzichtet werden. Dadurch können Zeit und Kosten des Herstellungsprozesses optimiert werden. Because the separating tool is designed both for separating out the at least one membrane and for transferring the at least one membrane to the joining tool, it is possible to dispense with a separate transfer device, such as a transfer robot. This can optimize the time and cost of the manufacturing process.
Das Transferieren umfasst dabei bevorzugt ein Transportieren der zumindest einen Membran zum Fügewerkzeug hin und ein Übergeben der zumindest einen Membran vom Trennwerkzeug an das Fügewerkzeug. Somit weist das Trennwerkzeug die Doppelfunktion des Heraustrennens der Membran sowie des Transferierens der Membran zum Fügewerkzeug auf.The transfer preferably comprises transporting the at least one membrane towards the joining tool and transferring the at least one membrane from the separating tool to the joining tool. Thus, the separating tool has the dual function of separating out the membrane and of transferring the membrane to the joining tool.
In einer bevorzugten Ausgestaltung des erfindungsgemäßen Verfahrens erfolgt das Transportieren der zumindest einen Membran entlang einer geradlinigen Bewegungsbahn, die im Wesentlichen parallel zur Schwerkraftrichtung verläuft. Besonders bevorzugt ist es dabei, dass das Transportieren der zumindest einen Membran entlang der geradlinigen Bewegungsbahn in Schwerkraftrichtung erfolgt. In einer solchen Ausgestaltungen ist es bevorzugt, dass das Fügewerkzeug oberhalb des Trennwerkzeugs angeordnet ist, so dass das Trennwerkzeug zum Ausführen des Trennprozesses in eine Richtung von unten nach oben verfährt und dabei aus dem plattenförmigen Körper die zumindest eine Membran heraustrennt. Daraufhin kann die herausgetrennte Membran vom Trennwerkzeug gehalten und entlang der geradlinigen Bewegungsbahn zum Fügewerkzeug transportiert und dort an das Fügewerkzeug übergeben werden.In a preferred embodiment of the method according to the invention, the transport of the at least one membrane takes place along a rectilinear trajectory which runs essentially parallel to the direction of gravity. It is particularly preferred that the transporting of the at least one membrane along the rectilinear trajectory in the direction of gravity takes place. In such a configuration, it is preferred that the joining tool is arranged above the separating tool, so that the separating tool moves in a direction from bottom to top for carrying out the separating process, thereby separating the at least one membrane from the plate-shaped body. Then the separated membrane can be held by the cutting tool and transported along the linear trajectory to the joining tool and there passed to the joining tool.
Alternativ kann das Transportieren der zumindest einen Membran entlang der geradlinigen Bewegungsbahn entgegengesetzt zur Schwerkraftrichtung erfolgen. In einer solchen Ausgestaltungen ist es bevorzugt, dass das Fügewerkzeug unterhalb des Trennwerkzeugs angeordnet ist, so dass das Trennwerkzeug zum Ausführen des Trennprozesses in eine Richtung von oben nach unten verfährt und dabei aus dem plattenförmigen Körper die zumindest eine Membran heraustrennt. Daraufhin kann die herausgetrennte Membran vom Trennwerkzeug gehalten und entlang der geradlinigen Bewegungsbahn zum Fügewerkzeug transportiert und dort an das Fügewerkzeug übergeben werden.Alternatively, the transport of the at least one membrane along the rectilinear trajectory opposite to the direction of gravity can take place. In such a configuration, it is preferable for the joining tool to be arranged below the separating tool, so that the separating tool moves in a direction from top to bottom in order to carry out the separating process and thereby separates the at least one membrane from the plate-shaped body. Then the separated membrane can be held by the cutting tool and transported along the linear trajectory to the joining tool and there passed to the joining tool.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens wird der plattenförmige Körper in einen Trennbereich, in dem das Trennwerkzeug die zumindest eine Membran aus dem plattenförmigen Körper heraustrennt, innerhalb der Werkzeugvorrichtung zugeführt. Bevorzugt ist der Trennbereich zwischen dem Trennwerkzeug und dem Fügewerkzeug angeordnet.In a further advantageous embodiment of the method according to the invention, the plate-shaped body is fed into a separating region, in which the separating tool separates the at least one membrane from the plate-shaped body, within the tool device. Preferably, the separation region between the cutting tool and the joining tool is arranged.
Bevorzugt ist es, wenn der plattenförmige Körper ein bandförmiger Körper aus Kunststoff, vorzugsweise PTFE, ist.It is preferred if the plate-shaped body is a band-shaped body made of plastic, preferably PTFE.
In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens ist das Trennwerkzeug ein Stanzwerkzeug, das dazu ausgebildet ist, die zumindest eine Membran aus dem plattenförmigen Körper mittels eines Stanzvorgangs auszustanzen. Zusätzlich oder alternativ ist es bevorzugt, dass das Fügewerkzeug ein Ultraschallwerkzeug, vorzugsweise eine Sonotrode, ist.In a further advantageous embodiment of the method according to the invention, the separating tool is a punching tool, which is designed to punch out the at least one membrane from the plate-shaped body by means of a punching operation. Additionally or alternatively, it is preferred that the joining tool is an ultrasonic tool, preferably a sonotrode.
Gemäß eines weiteren Aspekts der vorliegenden Erfindung ist eine Werkzeugvorrichtung vorgesehen, die ein Trennwerkzeug, das dazu ausgebildet ist, aus einem in die Werkzeugvorrichtung eingebrachten plattenförmigen Körper zumindest eine Membran herauszutrennen, und ein Fügewerkzeug aufweist, das dazu ausgebildet ist, die zumindest eine vom Trennwerkzeug herausgetrennte Membran aufzunehmen und an einem Gehäuse dauerhaft anzubringen. Dabei transferiert das Trennwerkzeug die zumindest eine herausgetrennte Membran an das Fügewerkzeug.According to a further aspect of the present invention, there is provided a tool device comprising a separating tool adapted to separate at least one diaphragm from a plate-shaped body inserted into the tool device, and a joining tool adapted to separate the at least one of the separating tool Membrane record and permanently attached to a housing. The separating tool transfers the at least one separated-out membrane to the joining tool.
