Abstract
Description
Dosiervorrichtungen werden verwendet, um ein flüssiges Medium, beispielsweise Klebstoff, Öl oder Schmiermittel, punktgenau und exakt dosiert auf ein Substrat aufzutragen. Solche Dosiervorrichtungen finden Anwendung in den unterschiedlichsten technischen Bereichen wie der Medizintechnik, der Mikroelektronik, der Optik und Optoelektronik. Durch die verschiedenen möglichen Anwendungen ergeben sich dementsprechend unterschiedlich gelagerte Anforderungen an die Dosiervorrichtung. Insbesondere besteht die Notwendigkeit, eine Dosiervorrichtung bereitzustellen, die effizient und universell einsetzbar ist.Dosing devices are used to be a liquid Medium, for example adhesive, oil or lubricant, precisely and apply precisely dosed to a substrate. Such dosing devices are used in a wide variety of technical areas such as medical technology, microelectronics, optics and optoelectronics. Through the different possible Applications therefore have different requirements to the dosing device. In particular, there is a need to provide a metering device that is efficient and universal can be used.
Bei den bekannten Dosiervorrichtungen befindet sich das Medium in einer Kammer, aus welcher es über eine Düse oder Kanüle austreten kann. Hierbei kann durch ein Ventil die Düse geöffnet und geschlossen werden, so daß die Menge des austretenden Mediums reguliert werden kann. Zum Auftragen des Mediums auf ein Substrat wird die Düse zunächst in Kontakt mit dem Substrat gebracht, so daß das flüssige Medium, welches bei geöffnetem Ventil aus der Düse ausläuft, auf das Substrat aufgebracht werden kann. Um nach Schließen des Ventils ein Ablösen des Mediums von der Düse zu gewährleisten, wird die Dosiervorrichtung von dem Substrat wieder entfernt.In the known metering devices the medium is in a chamber, from which it passes through a Nozzle or cannula can leak. The nozzle can be opened and closed by a valve be closed so that the Amount of the escaping medium can be regulated. To apply the Medium on a substrate, the nozzle is first in contact with the substrate brought so that the liquid Medium that is open when Valve out of the nozzle expires can be applied to the substrate. To close the Valve a peeling of the medium from the nozzle to ensure the dosing device removed from the substrate.
Nachteilig bei dieser Vorgehensweise ist der Zeitverlust, welcher dadurch auftritt, daß die Dosiervorrichtung zu Beginn des Auftragens des Mediums auf das Substrat zunächst in Kontakt mit dem Substrat gebracht und anschließend wieder von diesem wegbewegt werden muß. Hierdurch sind einer Verringerung der Taktzeit erhebliche Grenzen gesetzt.A disadvantage of this procedure is the loss of time caused by the metering device at the beginning of the application of the medium to the substrate first in Brought into contact with the substrate and then moved away from it again must become. This reduces the cycle time considerably set.
Ein weiterer Nachteil besteht darin, daß in schwer zugänglichen Bereichen oder Bauteilen, d.h. in Bereichen, wo die Dosiervorrichtung nicht in Kontakt mit dem Substrat gebracht werden kann, ein Aufbringen des Mediums nicht möglich ist.Another disadvantage is that in difficult accessible Areas or components, i.e. in areas where the metering device cannot be brought into contact with the substrate of the medium is not possible is.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Dosiervorrichtung bereitzustellen, durch welche die Taktzeit verkürzt und damit die Effizienz gesteigert werden kann.It is therefore the object of the present invention to provide a metering device by means of which the cycle time shortened and thus the efficiency can be increased.
Des weiteren ist es Aufgabe der vorliegenden Erfindung, eine Dosiervorrichtung bereitzustellen, mit welcher das Medium auch auf schwer zugängliche Bereiche aufgebracht werden kann.Furthermore, it is the task of the present Invention to provide a metering device with which Medium even on hard to reach Areas can be applied.
Die Aufgabe wird erfindungsgemäß durch die in Patentanspruch 1 gekennzeichnete Vorrichtung gelöst. Die Erfindung wird in ihren Unteransprüchen weitergebildet.The object is achieved by the characterized in claim 1 device solved. The Invention is developed in its subclaims.
Gemäß der vorliegenden Erfindung wird eine Dosiervorrichtung beschrieben mit einer Kammer zur Aufbewahrung eines Mediums, einer Austrittsöffnung durch welche das Medium aus der Kammer austreten kann und einem Ventil an der Austrittsöffnung zum Verschließen und Öffnen der Austrittsöffnung. Hierbei steht das Medium innerhalb der Kammer unter Druck steht und eine Nadel ist in Verlängerung der Austrittsöffnung angebracht.According to the present invention describes a dosing device with a chamber for storage of a medium, an outlet opening which the medium can escape from the chamber and a valve at the outlet to lock and opening the outlet opening. The medium inside the chamber is under pressure and a needle is in extension the outlet opening appropriate.
Indem das Medium in der Kammer durch Druckluft unter Druck steht, ist es möglich, durch schnelles Öffnen und Schließen des Ventils eine bestimmte Menge des Mediums austreten zu lassen, das sich durch den hohen Druck automatisch von der Dosiervorrichtung ablöst. Somit ist es nicht mehr nötig, die Dosiervorrichtung in Kontakt mit dem Substrat zu bringen, da das Medium auf das Substrat gejettet werden kann. Dies ermöglichst eine Verringerung der Taktzeit und damit einen effizienteren Ablauf.By the medium in the chamber by compressed air is under pressure, it is possible by quick opening and closing of the valve to let out a certain amount of the medium that automatically from the dosing device due to the high pressure replaces. So it is no longer necessary to bring the dosing device into contact with the substrate since the medium can be jetted onto the substrate. This enables a reduction in the cycle time and thus a more efficient process.
Des weiteren, indem eine Nadel an die Austrittsöffnung angebracht ist, kann das durch die Nadel austretende Medium auch auf Substrate in schwer zugänglichen Bereichen aufgebracht werden.Furthermore, by putting a needle on the exit opening attached, the medium escaping through the needle can also on substrates in hard to reach Areas are applied.
Vorzugsweise ist das Ventil ein Piezoventil.The valve is preferably a piezo valve.

Des weiteren handelt es sich bei dem Medium vorzugsweise um Klebstoff.Furthermore, it is about the medium preferably around glue.
Gemäß einer vorteilhaften Ausführungsform wird die Größe der Tropfen durch die Ventilöffnungszeit und/oder den Kammerdruck reguliert.According to an advantageous embodiment the size of the drops through the valve opening time and / or regulates the chamber pressure.
