Abstract

To form a sheet plate which has a multi-layer structure, at least in zones, an intermediate adhesive layer is applied to the surface of the smaller sheet before they are brought together. The adhesive is applied as a powder coating, with the powder resin covering the whole surface area of the smaller sheet, using a preheated surface or electrostatic coating.. The two layers are pressed together with heat, to cross link the adhesive, followed by cooling before the layered sheet is shaped by deep drawing.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von bereichsweise mehrlagigen Blech-Platinen, bei denen eine kleinere Platine unter Einbringen einer Klebstoffzwischenschicht mit einer größeren Platine zusammengefügt wird. Zum technischen Umfeld wird beispielshalber auf die DE 43 07 563 C2 verwiesen.The invention relates to a method for producing areas multilayer sheet metal circuit boards, in which a smaller circuit board under insertion an adhesive intermediate layer joined together with a larger board becomes. For technical reasons, for example, DE 43 07 563 C2 referred.

Blechplatinen, die bereichsweise aus mehreren, zumindest zwei übereinan­ derliegenden Lagen bestehen, können auch als Patchwork-Platinen be­ zeichnet werden. Bekannt sind derartige lokal verstärkte Platinen, die quasi durch Aufdoppeln eines zweiten kleineren Bleches auf die größere Grund- Platine gebildet werden, sowohl mit als auch ohne zwischen den einzelnen Lagen vorgesehene Klebstoffzwischenschicht. Letztere verbessert nicht nur die Festigkeit des Platinen-Verbundes, der im übrigen auch alleine durch gemeinsames Umformen und eine daraus entstehende formschlüssige Ver­ bindung gebildet werden kann, sondern wirkt auch als Korrosionsschutz- Maßnahme. Sheet metal plates, which consist of several, at least two, one above the other the existing layers can also be used as patchwork boards be drawn. Such locally reinforced boards are known, the quasi by doubling a second smaller sheet onto the larger base Circuit board are formed, both with and without between each Layers of adhesive provided. The latter doesn't just improve the strength of the circuit board assembly, which, by the way, also by itself common reshaping and a resulting positive Ver bond can be formed, but also acts as a corrosion protection Measure.  

Es hat sich herausgestellt, daß dann, wenn für die Klebstoffzwischenschicht herkömmliche pastöse Stahlblech-Rohbauklebstoffe verwendet werden, die­ se bei einem nachfolgenden Umformprozeß, insbesondere bei nachfolgen­ dem Tiefziehen der zusammengefügten Patchworkplatine aus dem Überlap­ pungsbereich der beiden (oder mehreren) Platinen herausgequetscht wer­ den und das Umform-Werkzeug in nicht tolerierbarem Maße verschmutzen. Die Klebstoffschicht kann jedoch auch durch eine zwischengelegte Klebstoff- Folie gebildet werden, welche allerdings schwierig zu applizieren ist und wo­ bei unerwünschte Lufteinschlüsse kaum vermeidbar sind. Ferner ist durch den notwendigen (und aufwendigen) Folienzuschnitt Abfall nicht zu vermei­ den.It has been found that when for the intermediate adhesive layer conventional pasty steel sheet raw materials are used, the se in a subsequent forming process, in particular in the case of successors deep-drawing the assembled patchwork board from the overlap area of the two (or more) boards squeezed out to contaminate the and the forming tool to an intolerable degree. However, the adhesive layer can also be Foil are formed, which is difficult to apply and where in the case of undesirable air pockets are hardly avoidable. Furthermore is by not to avoid the necessary (and expensive) film cutting waste the.

Eine Abhilfemaßnahme für diese geschilderte Problematik aufzuzeigen, ist Aufgabe der vorliegenden Erfindung.A remedial measure for these problems is to be shown Object of the present invention.

Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß vor dem Zu­ sammenfügen der Platinen die Klebstoffzwischenschicht auf die kleinere Platine in einem Pulverbeschichtungsverfahren aufgebracht wird. Vorteil­ hafte Weiterbildungen sind Inhalt der Unteransprüche.The solution to this problem is characterized in that before closing assemble the boards, the intermediate adhesive layer on the smaller Circuit board is applied in a powder coating process. Advantage further training is the content of the subclaims.

Erfindungsgemäß wird das die Klebstoffzwischenschicht bildende Material in Pulverform nach einem an sich herkömmlichen Pulverbeschichtungsverfah­ ren aufgebracht, und zwar wegen der einfacheren Handhabung bevorzugt auf die kleinere Platine. Besonders einfach und höchst wirkungsvoll ist es, wenn diese vollflächig mit einem geeigneten Pulverharz beschichtet wird, wobei dieser Pulverauftrag elektrostatisch oder auf die geeignet vorge­ wärmte Platine gezielt erfolgen kann.According to the invention, the material forming the intermediate adhesive layer in Powder form according to a conventional powder coating process ren applied, preferred because of the easier handling on the smaller board. It is particularly simple and highly effective if the entire surface is coated with a suitable powder resin, this powder application pre-electrostatically or on the suitable warmed circuit board can be targeted.

Anschließend hieran können die beiden miteinander zu verbindenden Plati­ nen maßgerecht zusammengefügt, d. h. aufeinander gelegt werden, wonach der so gebildete Verbund unter Temperatur gepreßt bzw. verpreßt werden sollte, so daß eine innige Klebverbindung, gebildet durch die Klebstoffzwi­ schenschicht, entsteht. Vor einem anschließenden gemeinsamen Tiefziehen sollte dieser Verbund jedoch abgekühlt werden. Die so angefertigte, noch ebene Patchwork-Platine kann danach umgeformt, d. h. zusammen tiefgezo­ gen werden, so wie dies in der eingangs genannten Schrift beschrieben ist.Subsequently, the two plati to be connected to one another Neatly assembled, d. H. on top of each other  the composite thus formed can be pressed or pressed under temperature should, so that an intimate adhesive bond, formed by the adhesive zwi layer, arises. Before a subsequent deep drawing together however, this composite should be cooled. The so made, yet flat patchwork board can then be reshaped, d. H. together deep-drawn be, as described in the document mentioned.

Wird das so gebildete Bauteil oder ein größerer Bauteilverbund, von wel­ chem dieses so gebildete Bauteil ein Bestandteil ist, später noch lackiert und einem darauffolgenden Lacktrocknungsprozess unter Wärmeeinwirkung un­ terzogen, so kann hierbei gleichzeitig die endgültige Aushärtung der Kleb­ stoffzwischenschicht bzw. des Pulverharzklebstoffes erfolgen. Dabei sollte grundsätzlich das die Klebstoffzwischenschicht bildende Pulver thermisch nachvernetzbar sein.If the component formed in this way or a larger component composite, by which chem this component thus formed is a component, later painted and a subsequent paint drying process under the influence of heat trained, so the final curing of the adhesive can simultaneously intermediate layer or powder resin adhesive. It should basically the powder forming the intermediate adhesive layer is thermal be crosslinkable.

Mit dem erfindungsgemäßen Verfahren können beliebige Patchworkplati­ nenformen und -abmessungen kostengünstig hergestellt werden, wobei es sich vorteilhafterweise um einen abfallfreien Prozeß handelt, da das im Pul­ verbeschichtungsprozeß überschüssige Pulver aufgefangen und rezykliert werden kann. Der vollflächige Klebstoff-Auftrag gewährleistet gleichzeitig optimalen Korrosionsschutz, wobei aufgrund der Pulverform keine Ver­ schmutzungsgefahr wie bei den eingangs genannten pastösen Klebstoffen besteht. Im übrigen läßt sich ein derartiges Pulverharz auch optimal dosieren und besitzt gegenüber den eingangs genannten Klebstoff-Folien den Vorteil, daß keine Luftblasen eingeschlossen werden können, so daß die Haftung der aufeinander liegenden Platinen als optimal bezeichnet werden kann.Any patchworkplati NEN shapes and dimensions are inexpensive to produce, it it is advantageously a waste-free process, since that in the pul Excess powder is collected and recycled can be. The full-surface adhesive application guarantees at the same time optimal corrosion protection, due to the powder form no Ver Danger of soiling as with the pasty adhesives mentioned at the beginning consists. In addition, such a powder resin can also be optimally metered and has the advantage over the adhesive films mentioned at the outset, that no air bubbles can be trapped, so that liability of the superimposed boards can be described as optimal.
