Abstract
Um bei einer Vorrichtung eines Die Bonder zur Dosierung und Aufbringung einer vorbestimmten Menge eines viskosen Klebemittels, mit einer Dispensdüse, welche einen von einer Wandfläche umgebenen Zuführkanal aufweist, durch den das Klebemittel zu einer Düsenplatte leitbar ist, in der mindestens eine Austrittsöffnung vorhanden ist, wobei der Zuführkanal in die mindestens eine Austrittsöffnung mündet und im Mündungsbereich eine Querschnittsfläche des Zuführkanals grösser ist als eine Querschnittsfläche der zumindest einen Austrittsöffnung, eine bessere Entlüftung zu ermöglichen wird vorgeschlagen im Zuführkanal (7) eine Zwangsführung vorzusehen, durch welche eine Front (12) des Klebemittels beim Befüllen der Dispensdüse (2) eine vorbestimmte Strömungsrichtung erhält, so dass das Klebemittel im wesentlichen das gesamte im Zuführkanal (3) befindliche Gas in Richtung auf zumindest eine Austrittsöffnung (10, 10a) zuführt. In a device for dispensing and applying a predetermined amount of a viscous adhesive, comprising a dispensing nozzle having a feed channel surrounded by a wall through which the adhesive is passed to a nozzle plate having at least one exit aperture therein the feed channel opens into the at least one outlet opening and in the mouth region a cross-sectional area of the feed channel is greater than a cross-sectional area of the at least one outlet opening to allow better ventilation is proposed in the feed channel (7) to provide a positive guide through which a front (12) of the adhesive when filling the dispensing nozzle (2) receives a predetermined flow direction, so that the adhesive substantially all the gas in the feed channel (3) located in the direction of at least one outlet opening (10, 10a) supplies.
