Description
Vorrichtung zum kontinuierlichen Umspritzen von aufDevice for continuous overmolding of on
Endlosstreifen angeordneten elektrischen oder mechanischen Elementen Die Erfindung bezieht sich auf eine Vorrichtung zum kontinuierlichen Umspritzen von auf Endlosstreifen angeordneten elektrischen oder mechanischen Elementen mit Kunststoffmasse aus Duro- oder Thermoplasten.Electrical or mechanical elements arranged in endless strips The invention relates to a device for continuous overmolding of electrical or mechanical elements arranged on endless strips Plastic compound made from thermosets or thermoplastics.
Elektrische Bauelemente z.B. Dioden, Transistoren, integrierte Schaltkreise, Kondensatoren, Widerstände usw.Electrical components e.g. diodes, transistors, integrated circuits, Capacitors, resistors, etc.
oder mechanische Bauelemente, wie Trägerstreifen für elektrische Kontaktstücke, werden umhüllt, um sie zu schützen oder ihnen ihre endgültigen geometrischen Abmessungen zu geben. Um die Montage zu vereinfachen, durchlaufen solche Bauelemente häufig auf einem Endlosstreifen gegurtet die Fertigung. Sie werden teilweise erst beim Abnehmer von dieser Verbindung gelöst.or mechanical components, such as carrier strips for electrical contact pieces, are enveloped to protect them or to give them their final geometrical dimensions admit. To simplify assembly, such components often go through the production taped on an endless strip. They are partly only when Customers released from this connection.
Das Umpressen und Umspritzen von Bauelementen oder Kleinteilen in der Elektrotechnik oder in der Mechanik ist an sich bekannt. Es werden dazu Werkzeuge#verwendet, die öffnen und schließen. In das geöffnete Werkzeug werden ein oder mehrere Teile eingelegt (DE-AS 25 14 488).The overmolding and overmolding of components or small parts in electrical engineering or mechanics is known per se. Tools # are used for this, which open and close. One or more parts are placed in the opened tool inserted (DE-AS 25 14 488).
Nach dem Schließen des Werkzeugs werden die Teile mit Kunststoff umhüllt durch Pressen oder Spritzen. Sie können erst nach dem öffnen des Werkzeugs entnommen werden.After the mold is closed, the parts are encased in plastic by pressing or spraying. They can only be removed after opening the mold will.
Die bekannten Verfahren und Vorrichtungen sind wegen der hohen nicht beeinflussbaren Fertigungszeiten wie z.B.The known methods and devices are not because of the high influenceable manufacturing times such as
Werkzeug schließen, Werkzeug öffnen, Teile entnehmen, Werkzeug reinigen, Teile einlegen und durch die Aushärtezeiten häufig sehr kostenungünstig. Im Gegensatz dazu stehen in zunehmendem Maße die Forderungen nach umspritzten oder umpressten Bauelementen mit exakten automatengerechten Außenabmessungen.Close tool, open tool, remove parts, clean tool, Insert parts and often very inexpensive due to the curing times. In contrast in addition, there are increasing demands for overmolded or overmolded Components with precise external dimensions that are suitable for machines.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, die es ermöglicht, kostengünstig elektrische oder mechanische Elemente mit einer Kunststoffhülle derart zu versehen, daß sie automatengerechte Außenabmessungen aufweisen.The invention is therefore based on the object of providing a device of to create mentioned type, which makes it possible to inexpensively electrical or mechanical To provide elements with a plastic cover in such a way that they are suitable for machines Have external dimensions.
Gemäß der Erfindung wird aie Aufgabe dadurch gelöst, daß ein auf einer Achse drehbares Rad vorgesehen ist, daß die Lauffläche des Rades mit achsparallel verlaufenden Vertiefungen (Formnester) versehen ist, daß ferner die Vertiefungen über einen vorbestimmten Bereich des Radumfanges von einer feststehenden dem Krümmungsradius der Lauffläche angepaßten Platte tangierend umfaßt und abgedichtet sind und daß am Anfang der Platte eine Einlaßöffnung für den Kunststoff vorgesehen ist.According to the invention, aie object is achieved in that a on one Axis rotatable wheel is provided that the running surface of the wheel with axially parallel extending depressions (mold cavities) is provided that also the depressions over a predetermined range of the wheel circumference from a fixed radius of curvature the tread adapted plate includes tangent and sealed and that an inlet opening for the plastic is provided at the beginning of the plate.
Die tangierend umfassende und abdichtende Platte kann z.B. aus Bronze bestehen. Die abdichtende Platte kann z.B. den halben Radumfang umfassen.The tangentially encompassing and sealing plate can be made of bronze, for example exist. The sealing plate can, for example, encompass half the circumference of the wheel.
Die Zeichnung zeigt schematisch und in Perspektive ein bevorzugtes Ausführungsbeispiel einer Vorrichtung der Erfindung. Es zeigt FIG 1 eine perspektivische Gesamtansicht der Vorrichtung, FIG 2 einen perspektivischen Ausschnitt.The drawing shows schematically and in perspective a preferred one Embodiment of an apparatus of the invention. It shows FIG 1 a perspective Overall view of the device, FIG. 2 shows a perspective detail.
In FIG 1 und 2 sind gleiche Teile mit den gleichen Bezugsziffern bezeichnet.In Figures 1 and 2, the same parts are denoted by the same reference numerals.
Die Vorrichtung gemäß der Erfindung arbeitet wie folgt.The device according to the invention works as follows.
In der Lauffläche 13 des sich drehenden Rades 14 befinden sich parallel zur Drehachse 15 die Vertiefungen 12 bzw. Formnester, in denen die gegurteten Bauelemente 11 umspritzt werden. Die Formnester 12 werden über den halben Radumfang von einer feststehenden, dem Krümmungsradius der Lauffläche 13 angepaßten Platte 16 tangierend umschlossen. Durch diese Platte 16 werden die Formnester 12 nach oben über den halben Durchmesser abgedichtet. Die gegurteten Bauelemente 11 werden eingeführt und durchlaufen in Richtung des Richtungspfeiles 20 in den Formnestern 12 liegend, von der Platte 16 abgedichtet, einen halben Radumfang, um am Ende der Platte 16 das Rad 14 wieder zu verlassen. Am Anfang der Platte 16 ist eine öffnung 17 vorgesehen, durch die der Kunststoff aus einer Spritzmaschine 18 eingespritzt wird. Das Rad 14 wird durch den Antrieb 19 in Bewegung gesetzt. Die kontinuierlich an der Einspritzstelle 17 vorbeilaufenden, in den Formnestern 12 des Rades 14 liegenden Bauelemente 11 werden dadurch umhüllt. Die zum Aushärten nötige Verweilzeit der umspritzten Teile im geschlossenen Werkzeug kann sowohl bei der Festlegung des Raddurchmessers als auch durch eine Regelung der Raddrehzahl variiert werden.In the running surface 13 of the rotating wheel 14 are parallel to the axis of rotation 15, the recesses 12 or cavities in which the taped components 11 are overmolded. The mold cavities 12 are over half the wheel circumference of a fixed plate 16 adapted to the radius of curvature of the running surface 13 enclosed. Through this plate 16, the mold cavities 12 are up over the half Diameter sealed. The taped components 11 are inserted and passed through lying in the direction of the arrow 20 in the mold cavities 12, from the plate 16 sealed, half a wheel circumference, to the end of the plate 16 the wheel 14 again to leave. At the beginning of the plate 16 an opening 17 is provided through which the plastic is injected from an injection molding machine 18. The wheel 14 is through the drive 19 is set in motion. The continuous at the injection point 17 Passing components 11 lying in the mold cavities 12 of the wheel 14 are enveloped thereby. The dwell time of the encapsulated parts required for curing in the closed Tool can be used both when defining the wheel diameter and through a Regulation of the wheel speed can be varied.
