Description

Die Erfindung betrifft eine Dosiereinrichtung zum Punkt weisen oder linienförmigen Aufbringen von Klebstoffen und anderen Flüssigkeiten, Pasten, Ölen.The invention relates to a metering device for pointwise or linear application of adhesives and other liquids, pastes, oils.

Die EP 1 208 945 A1 beschreibt ein Mikrodosiersystem, bei dem ein Klebstoff von einem Behälter in einen Dosierkopf befördert wird. Der Dosierkopf gibt den Klebstoff aus einer Austrittsdüse aus. Es wird beschreiben, dass im Dosierkopf ein piezoelektrischer Aktuator eingebaut ist, mit dem der Kleber tröpfchenweise ausgestoßen wird.The EP 1 208 945 A1 describes a microdosing system in which an adhesive is conveyed from a container into a dosing head. The dosing head releases the adhesive from an outlet nozzle. It will be described that a piezoelectric actuator is installed in the dosing head with which the adhesive is ejected in droplets.

Das Mikrodosiersystem PMDS 99 der Firma Reinhardt System- und Messelecronic GmbH Diessen-Obermühlhausen dosiert den Kleber mittels einer elektronisch gesteuerten Schlauchpumpe.The microdosage system PMDS 99 of the company Reinhardt System- and Messelecronic GmbH Diessen-Obermühlhausen doses the adhesive by means of an electronically controlled peristaltic pump.

Es ist weiterhin bekannt, dass bei Klebeprozessen die umgebende Luft mit ihren Inhaltsstoffen und Verunreinigungen (z. B. Sauerstoff, Wasser, Kohlendioxid, Staub) zu Störungen im Verarbeitungsprozess und Fehlern in den zu verarbeiteten Bauteilen führt. Daher werden hochwertige Klebeprozesse in mit Schutzgas gespülten Einhausungen durchgeführt. Nachteilig ist der hohe Aufwand. Die Einhausungen sind für die Arbeitskräfte schlecht zugänglich und die Effektivität des Klebeprozesses ist ungenügend.It is also known that during bonding processes, the surrounding air with its ingredients and impurities (eg oxygen, water, carbon dioxide, dust) leads to disruptions in the processing process and errors in the components to be processed. Therefore, high-quality adhesive processes are carried out in protective gas-purged enclosures. The disadvantage is the high cost. The enclosures are poorly accessible to the workforce and the effectiveness of the bonding process is insufficient.

Es ist daher eine Aufgabe der Erfindung die Verarbeitung von Klebstoffen und anderen Flüssigkeiten, Pasten oder Ölen einfacher und effektiver zu gestalten.It is therefore an object of the invention to make the processing of adhesives and other liquids, pastes or oils easier and more effective.

Es sollen die Eigenschaften, insbesondere die Qualität, von Klebeverbindungen zwischen zwei Bauteilen verbessert und reproduzierbarer werden.It should be the properties, in particular the quality of adhesive bonds between two components improved and reproducible.

Die Lösung der Aufgabe gelingt erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1.The object is achieved according to the invention with the characterizing features of claim 1.

Die Unteransprüche sind vorteilhafte Ausgestaltungen des Hauptanspruchs.The subclaims are advantageous embodiments of the main claim.

Die Dosiereinrichtung besteht aus einer elektronischen Steuerschaltung, welche mit einer Klebstoffdosiereinrichtung und einer Einrichtung zur Schutzgasversorgung verbunden ist. Sie besteht weiterhin aus einem Dosierkopf, welcher aus einem röhrenförmigen Aufnahmeteil und einer Dosiernadel aufgebaut ist. An dem röhrenförmigen Aufnahmeteil ist ein Anschluss an die Einrichtung zur Schutzgasversorgung vom Innendurchmesser her seitlich herausgeführt. Zum Gebrauch ist die Dosiernadel so in den trichterförmigen Bereich des Aufnahmeteils eingefügt, dass eine gasdichte Verbindung zwischen dem Aufnahmeteil und der Dosiernadel hergestellt ist. Die Dosiernadel weist einen Anschluss an die Klebstoffdosiereinrichtung auf.The metering device consists of an electronic control circuit, which is connected to an adhesive metering device and a device for protective gas supply. It also consists of a dosing head, which is constructed from a tubular receiving part and a dispensing needle. On the tubular receiving part, a connection to the device for protective gas supply is led out laterally from the inside diameter. For use, the dispensing needle is inserted into the funnel-shaped portion of the receiving part, that a gas-tight connection between the receiving part and the dispensing needle is made. The dispensing needle has a connection to the adhesive metering device.

Die gasdichte Verbindung zwischen dem Aufnahmeteil und der Dosiernadel ist durch eine Kegel-Konus-Passung hergestellt. Vorzugsweise ist die gasdichte Verbindung durch einen Dichtring hergestellt, welcher in eine Nut im trichterförmigen Bereich des Aufnahmeteils eingearbeitet ist.The gas-tight connection between the receiving part and the dispensing needle is made by a cone-cone fit. Preferably, the gas-tight connection is made by a sealing ring, which is incorporated in a groove in the funnel-shaped portion of the receiving part.

Die Verbindungen zu der Klebstoffdosiereinrichtung und zu der Einrichtung zur Schutzgasversorgung können starr ausgebildet sein.The connections to the adhesive metering device and to the device for protective gas supply can be rigid.

Vorzugsweise sind die Verbindungen jedoch flexibel ausgelegt, so dass eine manuelle Handhabung des Dosierkopfes ermöglicht ist.Preferably, however, the connections are designed to be flexible so that manual handling of the dosing head is made possible.

Die Erfindung findet insbesondere in der optischen und mechanischen Industrie Anwendung. Im Vordergrund steht das Fügen von komplexen mechanischen und optischen Komponenten mittels Kleber. Jedoch können mit Hilfe der erfindungsgemäßen Lösung auch andere flüssige Medien und pastöse Stoffe verarbeitet werden.The invention finds particular application in the optical and mechanical industries. In the foreground is the joining of complex mechanical and optical components by means of adhesive. However, with the aid of the solution according to the invention, other liquid media and pasty substances can also be processed.

Die Erfindung wird nachfolgend an Hand von Ausführungsbeispielen beschrieben.The invention will be described below with reference to exemplary embodiments.

2: Komponenten der Dosiereinrichtung 2 : Components of the dosing device

1 zeigt den Dosierkopf 1 der Dosiereinrichtung. Der Dosierkopf 1 besteht im Wesentlichen aus zwei Teilen, einem Aufnahmeteil 10, welches einen Kanal 11 zur Schutzgaseinleitung aufweist, sowie einer Dosiernadel 12. Die Dosiernadel 12 ist hohlförmig und weist in Achsrichtung gesehen einen Bereich als Anschluss 13 an eine Klebstoffdosiereinrichtung, einen Konusbereich 14 und dann einen nadelförmigen Bereich 15 auf. Das Aufnahmeteil 10 ist röhrenförmig und weist in Achsrichtung gesehen einen trichterförmigen Bereich 16 auf, in den der Konusbereich 14 der Dosiernadel 12 paßgenau eingefügt werden kann. An dem trichterförmigen Bereich 16 schließt sich der Kanal 11 zur Schutzgaszuführung an, welcher sich von einem Anschluss 17 zur Schutzgasversorgung bis hin zum Innendurchmesser des Aufnahmeteils 10 erstreckt. Die Kegelformen der beiden Teile können so genau aufeinander abgestimmt werden, dass eine Gasdichtheit hergestellt werden kann. Im Beispiel ist jedoch in den trichterförmigen Bereich 16 des Aufnahmeteils 10 eine Nut 18 eingearbeitet, in welche ein Rundring 19 eingelegt ist. Dieser dient zur Abdichtung gegenüber dem Konusbereich 14 der in das Aufnahmeteil 10 eingefügten Dosiernadel 12. 1 shows the dosing head 1 the metering device. The dosing head 1 consists essentially of two parts, a receiving part 10 which is a canal 11 for inert gas introduction, as well as a dispensing needle 12 , The dispensing needle 12 is hollow and has an area in the axial direction as a connection 13 to an adhesive metering device, a cone area 14 and then a needle-shaped area 15 on. The recording part 10 is tubular and has seen in the axial direction a funnel-shaped area 16 in which the cone area 14 the dispensing needle 12 can be inserted in an exact fit. At the funnel-shaped area 16 closes the channel 11 for inert gas supply, which is from a connection 17 for protective gas supply up to the inner diameter of the receiving part 10 extends. The conical shapes of the two parts can be coordinated so precisely that a gas tightness can be produced. In the example, however, is in the funnel-shaped area 16 of the receiving part 10 a groove 18 incorporated into which a round ring 19 is inserted. This serves to seal against the cone region 14 the in the receiving part 10 inserted dispensing needle 12 ,

Im Weiteren ist der Innendurchmesser des Aufnahmeteils 10 wesentlich größer als der Außendurchmesser der Dosiernadel 12. Eine an der Dosiernadel 12 vorhandene Austrittsöffnung für den Kleber 20 steht etwas vor einer Austrittsöffnung für das Schutzgas 21 hervor, so dass das Schutzgas einen auf ein Werkstück 22 aufgebrachten Klebstofftropfen 23 vollständig umspülen kann.In addition, the inner diameter of the receiving part 10 much larger than the outer diameter of the dispensing needle 12 , One at the dispensing needle 12 existing outlet for the glue 20 is something in front of an outlet for the inert gas 21 out, so that the inert gas on a workpiece 22 applied glue drops 23 can completely wash around.

2 zeigt schematisch den Aufbau der kompletten Dosiereinrichtung. Der Dosierkopf 1 besteht aus dem Aufnahmeteil 10 und der Dosiernadel 12. Der Anschluss 17 des Aufnahmeteils ist über eine flexible Schlauchverbindung mit einer Einrichtung zur Schutzgasversorgung 2 verbunden. Der Anschluss 13 der Dosiernadel 12 ist über eine weitere flexible Schlauchverbindung mit einer Klebstoffdosiereinrichtung 3 verbunden. Die Arbeit und das Zusammenwirken der Klebstoffdosiereinrichtung 3 und der Einrichtung zur Schutzgasversorgung 2 werden über eine elektronische Steuerschaltung 4 ausgelöst und aufeinander abgestimmt. 2 shows schematically the structure of the complete metering device. The dosing head 1 consists of the receiving part 10 and the dispensing needle 12 , The connection 17 The receiving part is via a flexible hose connection with a device for inert gas supply 2 connected. The connection 13 the dispensing needle 12 is via another flexible hose connection with an adhesive metering device 3 connected. The work and interaction of the adhesive metering device 3 and the device for protective gas supply 2 be via an electronic control circuit 4 triggered and coordinated.
