Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zum Herstellen von gegenüberliegenden Lötverbindungen an einer Sandwichanordnung, insbesondere einer solchen aus einer Solarzelle und auf gegenüberliegenden Oberflächenbereichen der Solarzelle angeordneten Lötbändern nach dem Oberbegriff des Anspruchs 1 bzw. dem des Anspruchs 6.The The present invention relates to a method and a device for making opposite solder connections at a sandwich arrangement, in particular such from a Solar cell and on opposite surface areas the solar cell arranged after solder strips the preamble of claim 1 or that of claim 6.
Bei der Herstellung derartiger Sandwichanordnungen wird der Lötkopf auf das ihm zugewandte Lötband kontaktierend gebracht und soweit erwärmt, dass sowohl das oben auf der Solarzelle liegende als auch das unterhalb der Solarzelle liegende Lötband derart erwärmt wird, dass das verwendete Lot, bspw. Zinn, schmilzt. Bei derartigen Lötvorgängen, bei denen die beiden Lötbänder ein Flussmittelbad durchlaufen und bspw. verzinnt werden, besteht ein Problem darin, dass der Lötkopf verschmutzt und nach einiger Zeit einen derartigen Verschmutzungsgrad erreicht hat, der zu einer reduzierten Wärmeübertragung vom Lötkopf auf die zu verbindenden Elemente führt. Dies wiederum resultiert in einer mangelhaften Lötverbindung. Um dies zu vermeiden, muss der Lötkopf von Zeit zu Zeit gereinigt werden, was zu einer Unterbrechung des Arbeitsvorganges führt und darüber hinaus aufwändig ist.at The production of such sandwich arrangements, the soldering head the soldering tape facing him brought in contact and heated as far as that both on top the solar cell lying as well as lying below the solar cell Solder tape like this heated is that the solder used, for example, tin, melts. In such Soldering, at which the two soldering tapes Pass through flux bath and, for example, tinned, there is a Problem is that the soldering head contaminated and reached after some time such a degree of contamination that has a reduced heat transfer from the soldering head leads to the elements to be connected. This in turn results in a defective solder joint. To avoid this, the soldering head must be be cleaned from time to time, resulting in an interruption of the Operating procedure leads and above elaborate is.
Aufgabe der vorliegenden Erfindung ist es deshalb, ein Verfahren und eine Einrichtung zum Herstellen von einander gegenüberliegenden Lötverbindungen an einer Sandwichanordnung der eingangs genannten Art zu schaffen, bei dem bzw. bei der ein Verschmutzen des Lötkopfes und dessen negative Folgen im Wesentlichen vermieden sind.task The present invention is therefore a method and a Device for producing opposite solder joints to create a sandwich arrangement of the type mentioned, in which or at the fouling of the soldering head and its negative Consequences are essentially avoided.
Zur Lösung dieser Aufgabe sind bei einem Verfahren und einer Einrichtung zum Herstellen von gegenüberliegenden Lötverbindungen einer Sandwichanordnung der eingangs genannten Art die im Anspruch 1 bzw. im Anspruch 6 angegebenen Merkmale vorgesehen.to solution This object is achieved in a method and a device for Making opposite solder connections a sandwich arrangement of the type mentioned in the claim 1 or specified in claim 6 features provided.
Durch die erfindungsgemäßen Maßnahmen ist erreicht, dass der Lötkopf nicht mehr mit dem mit Flussmittel behafteten und verzinnten Lötband in Berührung kommt, so dass das Löten kontaktlos erfolgt und der Lötkopf als solcher praktisch keiner Verschmutzung mehr unterliegt. Dies wird durch das Wärmeübertragungsmedium erreicht, das seine Wärme auf die beiderseits der Solarzelle angeordneten mit dem betreffenden Lot, wie Lötzinn, versehenen Lötbänder abgibt. Ein Anhalten der Produktion wegen einer Lötkopfreinigung ist deshalb nicht mehr notwendig.By the measures according to the invention achieved that the soldering head no longer with the fluxed and tinned soldering tape in contact comes, so the soldering contactless and the soldering head as such practically no more pollution is subject. This is through the heat transfer medium that achieves its warmth on the both sides of the solar cell arranged with the relevant Solder, like solder, provided soldering tapes. Stopping the production because of a Lötkopfreinigung is therefore not necessary anymore.
Gemäß den Merkmalen nach Anspruch 2 bzw. 7 ist es auch möglich, zur Verhinderung von Oxidationen das Wärmeübertragungsmedium in Form eines Schutzgases zuzuführen.According to the characteristics according to claim 2 or 7, it is also possible to prevent Oxidations the heat transfer medium in the form of a protective gas.
Vorteilhafte Ausgestaltungen bezüglich des Erwärmens des Wärmeübertragungsmediums und dessen Zuführen auf den Bereich der zu schaffenden Lötverbindung ergibt sich aus den Merkmalen des Anspruchs 8 und/oder 9.advantageous Embodiments regarding of heating the heat transfer medium and its feeding to the area of the solder joint to be created results from the features of claim 8 and / or 9.
Zweckmäßigerweise ist der Lötkopf gemäß den Merkmalen des Anspruchs 10 in axialer Richtung bewegbar, um einerseits eine entsprechende Wärmeübertragungsdistanz einstellen zu können, und um andererseits gemäß den Merkmalen nach Anspruch 4 bzw. 11 einen Niederhalter betätigen bzw. einstellen zu können. Dabei kann es zweckmäßig sein, die Merkmale nach Anspruch 12 und/oder 13 vorzusehen. Dies ist eine wenig aufwändige Maßnahme für einen Niederhalter, ohne dass der Strom des Wärmeübertragungsmediums nachteilig beeinflusst wird.Conveniently, is the soldering head according to the characteristics of claim 10 in the axial direction movable, on the one hand a corresponding heat transfer distance to be able to adjust and on the other hand according to the features according to claim 4 or 11 actuate a hold-down or can set. there it may be appropriate to provide the features of claim 12 and / or 13. this is a little expensive measure for one Hold down without the flow of heat transfer medium adversely being affected.
Vorteilhafte Ausgestaltungen hinsichtlich der Beeinflussung der Prozessparameter ergeben sich aus den Merkmalen nach Anspruch 5 bzw. eines oder mehrerer der Ansprüche 14 bis 16.advantageous Embodiments with regard to influencing the process parameters arise from the features of claim 5 or one or more the claims 14 to 16.
Bei Lötverbindungen zwischen einer Vielzahl von aneinandergereihten Solarzellen und längs der Solarzellenreihe angeordneten Lötbändern ist es zweckmäßig, die Merkmale nach Anspruch 17 und/oder 18 vorzusehen.at solder connections between a plurality of juxtaposed solar cells and along the solar cell array arranged soldering tapes is it is expedient, the To provide features according to claim 17 and / or 18.
