Description
Verfahren zur Beschichtung der Stirnseiten von elektrischen Bauelementen, insbesondere von elektrischen Wickelkondensatoren, mittels Flammspritzverfahrens.Process for coating the end faces of electrical components, in particular of electrical wound capacitors, using the flame spraying process.
Die Erfindung betrifft ein Verfahren zur Beschichtung der Stirnseiten von elektrischen Bauelementen, insbesondere von elektrischen Wickelkondensatoren, mittels Blammspritzverfahrens, bei dem mehrere Bauelemente gemeinsam einem Schoopstrahl ausgesetzt werden.The invention relates to a method for coating the end faces of electrical components, in particular of electrical wound capacitors, by means of flame spraying, in which several components together form a Schoop jet get abandoned.
Ein derartiges Verfahren ist bereits bekannt. Es läßt sich jedoch nicht ohne weiteres für Bauelemente aus wärmeempfindlichen Materialien anwenden; insbesondere Wickelkondensatoren aus Polypropylenfolien, Polystyrolfolien oder ähnlichen wärmeempfindlichen Stoffen werden durch die Erwärmung beim Beschoopen teilweise beschädigt, was zu Ausfällen führt. Dies tritt in der ersten Eontaktierphase, der sogenannten Bekeimung, besonders stark auf. In dieser Phase werden nämlich relativ heiße Metallteilchen auf die Stirnflächen gespritzt, um eine gute Verankerung der Schoopschichten zu erreichen.Such a method is already known. However, it can do not readily apply to components made of heat-sensitive materials; in particular wound capacitors made of polypropylene films, polystyrene films or the like Heat-sensitive materials are partially affected by the warming up during Beschoopen damaged, which leads to failures. This occurs in the first contact phase, the so-called germination, particularly strong. In this phase are namely relative hot metal particles are sprayed onto the end faces to ensure a good anchorage of the To achieve Schoopschichten.
Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht darin, eine einwandfreie Stirnkontaktierung von wärmeempfindlichen Bauelementen mittels Schoopverfahrens in einem Verfahren der eingangs beschriebenen Art zu erreichen und dabei eine Beschädigung der Bauelemente zu vermeiden.The object on which the present invention is based is to a perfect frontal contact of heat-sensitive components by means of To achieve Schoop method in a method of the type described above and avoid damaging the components.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß vor dem Flammspritzen zwischen die Bauelemente ein gegen die thermische und mechanische Beanspruchung durch den Schoopstrahl beständiger Kühl schlauch eingelegt und dieser mit Kühlmittel gefüllt und beidseitig verschlossen wird.This object is achieved in that before to the Flame spray between the components against the thermal and mechanical Stress from the Schoopstrahl resistant cooling hose inserted and this filled with coolant and sealed on both sides.
Das Volumen, die Form und die Größe des Kühlschlauches sind dabei so dimensioniert, daß eine einmalige Eühlmittel-Büllung zur Kühlung beim Flammspritzen (Beschoopen) ausreicht und daß die Mantelflächen der Bauelemente möglichst weitgehend durch den Kühl schlauch abgedeckt werden. Dieses Verfahren hat den Vorteil, daß durch den Kühlschlauch einerseits eine Kühlung erfolgt, andererseits die Bauelemente in ihrer Lage gehalten und die Mantelflächen der Bauelemente zumindest teilweise vor Schoopmetall geschützt werden, also leichter gereinigt werden können, eventuell sogar überhaupt nicht gereinigt werden müssen.The volume, shape and size of the cooling hose are included Dimensioned so that a one-time Eühlmittel-Büllung for cooling during flame spraying (Beschoopen) is sufficient and that the outer surfaces of the components as far as possible covered by the cooling hose. This method has the advantage that cooling takes place on the one hand through the cooling hose, on the other hand the components held in their position and the outer surfaces of the components at least partially be protected from Schoopmetall, so can be cleaned more easily, possibly not even need to be cleaned at all.
Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, daß als Kühlschlauch ein klebstoffbeschichteter, thermisch gut leitfähiger Profilschlauch außen zu liegen kommt, so daß er sowohl als Halt für die Bauelemente als auch als Abdeckung der Mantelflächen dient. Diese Ausgestaltung wird besonders vorteilhaft zum Beschoopen einer sehr großen Zahl von Bauelementen verwendet.An advantageous embodiment of the invention is that as Cooling hose an adhesive-coated profile hose with good thermal conductivity comes to lie on the outside, so that it serves as both a support for the components as well as Covering the lateral surfaces is used. This configuration is particularly advantageous used for Beschoopen a very large number of components.
Sollen relativ schwere Bauelemente beschoopt werden, so empfiehlt es sich, daß die Bauelemente in einem tontaktierrahmen in Lagen geschichtet werden und daß der Kühlschlauch mäanderförmig zwischen die einzelnen Lagen der Bauelemente und zwischen den Rahmen und die oberste bzw. unterste Lage der Bauelemente eingeführt und kurz vor dem Beschoopen der Bauelemente mit Kühlmittel gefüllt wird.If relatively heavy components are to be shooped, it is recommended it is that the components are layered in a contact frame and that the cooling hose meanders between the individual layers of the components and inserted between the frame and the top or bottom layer of the components and is filled with coolant shortly before the components are Beschoopen.
Als Kühlmittel eignet sich z.B. ein beliebiges 1, dessen Siedepunkt so hoch ist, daß er durch die Erwärmung beim Beschoopen nicht erreicht wird. Das Kühlmittel wird vor dem Einfüllen zweckmäßigerweise in einem Kühlaggregat entsprechend abgekühlt. Nach dem Flammspritzen wird das Kühlmittel abgelassen, die Bauelemente werden vom Eühlschlauch getrennt und von Schoopmetallresten an den Mantelflächen gereinigt.Any 1, its boiling point, is suitable as a coolant is so high that it is not reached by the warming up during Beschoopening. That Coolant is expediently appropriately in a cooling unit before filling cooled down. After the flame spraying, the coolant is drained off, the components are separated from the Eühlschlauch and from Schoopmetallreste on the jacket surfaces cleaned.
Die Reinigung des Eühlschlauches von Schoopmetall bereitet keine Schwierigkeiten, da Metallschichten von Elastomeren wesentlich leichter abfallen als von anderen Stoffen.The cleaning of the cooling hose from Schoopmetall does not cause any difficulties, because metal layers from elastomers fall off much more easily than from others Fabrics.
Die Erfindung wird nun an Hand von zwei Figuren näher erläutert; sie ist nicht auf die in den Figuren gezeigten Beispiele beschränkt.The invention will now be explained in more detail with reference to two figures; she is not limited to the examples shown in the figures.
Fig. 1 zeigt ein Schooprad mit erfindungsgemäß angeordneten Bauelementen in teilweise gebrochener Ansicht, Fig. 2 zeigt einen Schooprahmen mit erfindungsgemäß angeordneten Bauelementen.Fig. 1 shows a Schooprad with components arranged according to the invention in a partially broken view, Fig. 2 shows a Schooprahmen according to the invention arranged components.
In Fig. 1 sind auf einem Schooprad 1 mehrere Lagen elektrischer Bauelemente 3 befestigt. Diese sind durch einen Profilschlauch 2, der mit Klebstoff (durch Punkte dargestellt) an seiner Oberfläche beschichtet ist, gegurtet. Der Profilschlauch 2 liegt jeweils außen, bildet also während des Beschoopens einen Schutz auch der äußersten Lage der Bauelemente 3. Er ist mit Kühlmittel gefüllt. Er schmiegt sich daher an die Mantelflächen der Bauelemente 3 an.In Fig. 1, several layers of electrical components are on a Schooprad 1 3 attached. These are connected by a profile hose 2, which is secured with glue (by dots shown) is coated on its surface, strapped. The profile hose 2 is on the outside, so also forms a protection during the boooping outermost position of the components 3. It is filled with coolant. He hugs therefore to the outer surfaces of the components 3.
In Fig. 2 sind Bauelemente 5 und ein Profilschlauch 6 in einem Schooprahmen 4 angeordnet. Der Profilschlauch 6 verläuft mäanderförmig zwischen den einzelnen Lagen der Bauelemente 5 und zwischen der untersten bzw. obersten Lage der Bauelemente 5 und dem Schooprahmen 4. Der Profilschlauch 6 ist mit Kühlmittel gefüllt. Er schmiegt sich daher an die Mantelflächen der Bauelemente an.In Fig. 2 components 5 and a profile hose 6 are in a Schooprahmen 4 arranged. The profile hose 6 runs in a meandering shape between the individual Layers of the components 5 and between the lowest and topmost layer of the components 5 and the Schooprahmen 4. The profile hose 6 is filled with coolant. He hugs therefore adhere to the outer surfaces of the components.
