Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zum Herstellen einer Lötverbindung zwischen zwei Elementen, insbesondere zwischen einer Solarzelle und einem Leiterband, nach dem Oberbegriff des Anspruchs 1 beziehungsweise dem des Anspruchs 7.The The present invention relates to a method and a device for making a solder joint between two elements, in particular between a solar cell and a conductor strip, according to the preamble of claim 1 and that of claim 7.
Beispielsweise bei der Herstellung von sogenannten Solarzellenstrings werden die Solarzellen mit Leiterbeziehungsweise Lötbändern versehen und über diese mit benachbarten Solarzellen lötend verbunden. Dabei erfolgt das lötende Anbringen der Leiter- beziehungsweise Lötbänder an den Solarzellen abwechselnd auf deren Ober- und Unterseite.For example in the production of so-called solar cell strings, the Provided solar cells with Leiterbeziehungsweise soldering and over these soldering with neighboring solar cells connected. The soldering takes place Attaching the conductor or soldering tapes to the solar cells alternately on the top and bottom.
Bei derartigen Lötvorgängen, bei denen eines der beiden miteinander zu verlötenden Elemente, hier das Leiterbeziehungsweise Lötband ein Flussmittelbad durchläuft und verzinnt wird, besteht ein Problem darin, dass der Lötstempel verschmutzt und nach einiger Zeit einen derartigen Verschmutzungsgrad erreicht, der zu einer reduzierten Wärmeübertragung vom Lötstempel auf die zu verbindenden Elemente führt. Dies wiederum resultiert in einer mangelhaften Lötverbindung. Um dies zu vermeiden, muss der Lötstempel von Zeit zu Zeit gereinigt werden, was zu einer Unterbrechung des Arbeitsvorganges führt und darüber hinaus aufwändig ist.at such soldering, in which one of the two elements to be soldered together, here the Leiterbeziehungsweise solder ribbon goes through a flux bath and tinned, there is a problem in that the soldering punch contaminated and after some time such a degree of pollution achieved, which leads to a reduced heat transfer from the soldering punch leads to the elements to be connected. This in turn results in a defective solder joint. To avoid this, the soldering punch needs to 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 einer Lötverbindung der eingangs genannten Art zu schaffen, bei dem beziehungsweise bei der ein Verschmutzen des Lötstempels und dessen Folgen im Wesentlichen vermieden sind.task The present invention is therefore a method and a Device for producing a solder joint of the aforementioned To create kind, in which or at the one fouling of the soldering stamp and its consequences are substantially avoided.
Zur Lösung dieser Aufgabe sind bei einem Verfahren und einer Einrichtung zum Herstellen einer Lötverbindung der eingangs genannten Art die im Anspruch 1 beziehungsweise die im Anspruch 7 angegebenen Merkmale vorgesehen.to solution This object is achieved in a method and a device for Making a solder joint of the type mentioned in the claim 1 and the Provided in claim 7 specified features.
Durch die erfindungsgemäßen Maßnahmen ist erreicht, dass der Lötstempel nicht mehr unmittelbar mit dem flussmittelbehafteten und verzinnten Element in Berührung kommt, so dass der Lötstempel als solcher so gut wie keiner Verschmutzung mehr unterliegt. Dies verhindert die zwischengefügte Schutzschicht, die auch während der Arbeitsvorgänge ganz oder bereichsweise ausgetauscht werden kann. Ein Anhalten der Produktion zur Lötstempelreinigung ist deshalb nicht mehr notwendig.By the measures according to the invention achieved that the soldering stamp no longer directly with the fluxed and tinned Element in contact comes, so the soldering stamp as such as virtually no pollution is more subject. This prevents the interposed protective layer, that too during of the work processes can be exchanged completely or partially. A stop of the Production for soldering stamp cleaning is therefore no longer necessary.
Vorteilhafte Ausgestaltungen hinsichtlich der Anordnung und Ausgestaltung der Schutzschicht ergeben sich aus den Merkmalen jeweils eines der Ansprüche 2 und 3 beziehungsweise 8 und 9.advantageous Embodiments with regard to the arrangement and design of the Protective layer resulting from the features of each of claims 2 and 3 or 8 and 9.
Vorteilhafte Ausgestaltungen hinsichtlich der Auswechselbarkeit der Schutzschicht ergeben sich aus den Merkmalen eines der Ansprüche 4 und 5 beziehungsweise 9 bis 11. Dabei wird das Auswechseln der Schutzschicht beziehungsweise das Weitertakten einer Endlosschutzfolie beispielsweise dann vorgenommen, wenn nach einer entsprechenden Anzahl von Lötvorgängen sich bei der Schutzschicht auf Grund ihrer Verschmutzung die Wärmeübertragungseigenschaften verschlechtern oder die Schutzschicht porös geworden ist, so dass die Schutzqualitätsvorgabe für den Lötstempel nicht mehr ausreichend ist.advantageous Embodiments regarding the interchangeability of the protective layer emerge from the features of one of claims 4 and 5 respectively 9 to 11. Here, the replacement of the protective layer or the indexing of an endless protective film is carried out, for example, then if, after a corresponding number of soldering operations, the protective layer due to their pollution deteriorate the heat transfer properties or the protective layer porous has become, so that the protection quality specification for the soldering punch is no longer sufficient is.
Herstellungstechnische Vereinfachungen ergeben sich aus den Merkmalen des Anspruchs 6 beziehungsweise 12.Technical production Simplifications emerge from the features of claim 6 or 12th
