Description
Verfahren zur Herstellung von SolargeneratorenProcess for the production of solar generators
Die Erfindung befasst sich mit einem Verfahren gemäß dem Oberbegriff des Anspruchs 1.The invention is concerned with a method according to the preamble of claim 1.
Es sind sogenannte Verbundgläser bekannt, z.B. als Windschutzscheiben für Kraftfahrzeuge, bei denen zwei Glasscheiben und eine zwischen ihnen eingebrachte Klebefolie durch Anwendung von Druck und Temperatur zu einem einheitlichen, glasklaren Verbund verschmolzen werden.So-called laminated glasses are known, e.g. as windshields for motor vehicles with two panes of glass and one inserted between them Adhesive film by applying pressure and temperature to a uniform, crystal clear Composite to be merged.
Es ist weiterhin bei der Herstellung von Solargeneratoren bekannt, diese in einer Vakuum-Kammer zu positionieren, wobei der technische Aufbau des Generators aus den Solarzellen, ober- und unterseitig davon angeordneten Schmelzkleberfolien und zwei äußeren Glasscheiben bestehen kann.It is also known in the manufacture of solar generators, to position these in a vacuum chamber, with the technical structure of the generator from the solar cells, top and bottom of them arranged hot melt adhesive films and can consist of two outer panes of glass.
Nach dem Evakuieren wird über eingebaute Heizungen der Verbund aufgeheizt und dann mechanisch solange belastet, bis die Schmelzkleberfolie alle Fugen ausgefüllt hat. Der notwendige äußere Andruck ist temperatur- und zeitabhängig, bedingt durch die Zähigkeit des Klebers. Auch hier sind verschiedene Andruckverfahren in Anwendung, die beispiels- weise über federbelastete Platten wirken oder auch über gespannte Folien, die den Differenzandruck nutzen.After evacuation, the assembly is heated up via built-in heaters and then mechanically loaded until the hotmelt adhesive film fills all the joints Has. The necessary external pressure is temperature and time dependent, due to the tenacity of the glue. Here, too, various pressure methods are used, the example act wisely via spring-loaded plates or also via stretched foils that use differential pressure.
Wenn die Ferttgungskapazität erhöht werden soll, so ist hier insbesondere ihre Abhängigkeit von der vorhandenen Heizfläche zu nennen, da diese für einen Herstellungsvorgang jeweils nur einmal belegt werden kann. Dieser diskontinuierliche Betrieb wird noch erschwert durch die Bereitstellung und Beschickung mit dem lose zusammengelegten Aufbau des Generators. Hierfür sind besondere Hilfsvorrichtungen notwendig, abgesehen von der Formatabhängigkeit bei der Auslegung der Heizflächen.If the production capacity is to be increased, this is particularly important their dependence on the existing heating surface should be mentioned, as this is necessary for a manufacturing process can only be used once at a time. This discontinuous operation is still going on made difficult by the provision and loading with the loosely folded Structure of the generator. Special auxiliary devices are necessary for this, apart from on the format dependency in the design of the heating surfaces.
Die für eine Kapezitätserhöhung notwendigen Investitions-und Herstellungskosten sind erheblich. Die technischen Mängel derart hergestellter Solargeneratoren sind u. U. nicht planparallele Glasplatten im Randbereich (Spannungen können zu Delaminationen führen), von denen die Zellen üblicherweise einen Abstand von etwa 2 cm haben, sowie ein Verschwimmen der in den Randbereichen angeordneten Solarzellen zum Rand durch das Fließen des Schmelzklebers.The investment and manufacturing costs necessary for an increase in capacity are substantial. The technical shortcomings of solar generators produced in this way are Possibly not plane-parallel glass plates in the edge area (tension can lead to delamination lead), from which the cells are usually about 2 cm apart, as well as a blurring of the solar cells arranged in the edge areas towards the edge the flow of the hot melt adhesive.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, mit dem ohne wesentlichen technischen Mehraufwand eine Steigerung der Produktionskapazität erzielbar ist.The invention is therefore based on the object of providing a method of To create the type mentioned at the beginning, with the without significant additional technical effort an increase in production capacity can be achieved.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 genannten Merkmale gelöst. Die besonderen Vorteile des Verfahrens nach der Erfindung sind darin zu sehen, daß sich Solargeneratoren auf der Basis industrieller Prozesse rationeller herstellen lassen, wobei ein optisch klarer und dauerhafter Verbund entsteht, der frei von Lunkern oder Blasen ist. Weiterhin ist der relativ geringe apparative Mehraufwand und die kostengünstigen Betriebsmittel zur Erzielung hoher Fertigungskapazitäten zu nennen. Auch ist ein kontinuierlicher Herstellungsprozeß durch die Beschickung eines Transportbandes gewährleistet, an dessen Ende das fertige Produkt anfällt. Ein weiterer Vorteil liegt in dem formatunabhängigen Betrieb eines derartigen Bandes. Lediglich die elastischen Ringe um die Kanten des Verbundes sind in ihrer Gr-öAe anzupassen. Schließlich ist als Vorteil herauszustellen, daß die so erzeugten Generatoren absolut planparallele Glasplatten aufweisen. Darüber hinaus ist auch die Anwendung sogenannter strukturierter Abdeckscheiben, die wegen ihres günstigeren optischen Verhaltens in zunehmendem Maße eingesetzt werden, problemlos möglich.This object is achieved according to the invention by the features in the characterizing part of the claim 1 mentioned features solved. The particular advantages of the method according to the invention can be seen in the fact that solar generators are based on industrial processes Can be produced more efficiently, with a visually clear and permanent bond arises that is free of voids or bubbles. Furthermore, the is relatively low additional equipment and the cost-effective resources to achieve high To name manufacturing capacities. Also is a continuous manufacturing process guaranteed by the loading of a conveyor belt, at the end of which the finished Product accrues. Another advantage is the format-independent operation of a such a band. Only the elastic rings around the edges of the composite are to adapt in their size. Finally, it should be pointed out as an advantage that the Generators produced in this way have absolutely plane-parallel glass plates. Furthermore is also the use of so-called structured cover disks, which because of their more favorable optical behavior are used to an increasing extent, problem-free possible.
Weiterbildungen der Erfindung sind in den Merkmalen der Unteransprüche dargestellt.Developments of the invention are in the features of the subclaims shown.
In der Zeichnung sind Ausftihrungsbeisplele für nach dem Verfahren nach der Erfindung hergestellte Solargeneratoren dargestellt. Es zeigen Fig. 1 einen Solargenerator mit umlaufendem Dichtring Fig. 2 den vergrößert gezeichneten Randbereich vor und nach Anwendung des Verfahrens Fig. 3 einen zusammengelegten Generator Fig. 4 eine Prinzip-Darstellung eines Herstellungsverfahrens und Fig. 5 eine Variante des Verfahrens.In the drawing there are examples of the execution of the procedure Solar generators manufactured according to the invention are shown. 1 shows a Solar generator with circumferential sealing ring Fig. 2 shows the enlarged edge area before and after application of the method Fig. 3 shows a combined generator Fig. 4 shows a basic illustration of a production method and FIG. 5 shows a variant of the procedure.
Gemäß Fig. 1 sind zwischen einer oberen und einer unteren Glasscheibe 1 und 2 sowie einer oberen und einer unteren Schmeizkleberfolie 3 und 4, die z. 8. aus Polyvenyl-Uutyral oder Ethyl-Vinyl-Azetat bestehen können, die Solarzellen 6 eingefügt. Zusätzlich wird im Randbereich um den Generator herum in der Ebene der Solarzellen 6 eine Folie 5 eingelegt, die die gleiche Dicke wie die -Solarzellen selbst au-fweist.According to Fig. 1 are between an upper and a lower pane of glass 1 and 2 and an upper and a lower hot melt adhesive film 3 and 4, the z. 8. The solar cells can consist of polyvinyl utyral or ethyl vinyl acetate 6 inserted. In addition, in the edge area around the generator in the plane of the solar cells 6, a film 5 is inserted which has the same thickness as the solar cells himself.
Um die sandwichartig lose z-usammengelegten Komponenten wird jetzt ein geschlossener elastischer Ring 7 gelegt, der inseitig einen umlaufenden, zum Glas offenen Hohiring 8 aufweist und dessen Lippen 9 und 10 an der oberen und unteren Scheibe 1 und 2 anliegt. Über einen nicht dargestellten Ansaugstutzen wird der Hohlring 8 und damit auch die Zellen-und Folienzwischenräume evakuiert. Gleichzeitig wird durch den Andruck des äußeren Luftdruckes dieser lose Aufbau fixiert, was für jede weitere Handhabung wichtig ist.To the sandwich-like loosely put together components is now a closed elastic ring 7 placed, the inside a circumferential, for Glass has open hollow ring 8 and its lips 9 and 10 on the upper and lower disc 1 and 2 are present. The hollow ring is via an intake port, not shown 8 and thus also the cell and foil spaces are evacuated. At the same time will This loose structure is fixed by the pressure of the external air pressure, something for everyone further handling is important.
In Fig. 2a ist der Randbereich des lose zusammengelegten Verbundes mit der oberen und unteren Glasabdeckung 1, 2, der oberen und unteren Schmelzkleberfolie 3, 4 sowie der Randfolie 5 gezeigt, die etwa die Stärke der Solarzelle 6 besitzt und die zusammengeschalteten Zellen allseitig umschließt. Nach Durchführung des Herstellungsverfahrens wird aus dem lose zusammengefügten Bauteilen ein fester Verbund, wie in Fig. 2b dargestellt ist.In Fig. 2a is the edge area of the loosely folded composite with the upper and lower glass cover 1, 2, the upper and lower hot melt adhesive film 3, 4 and the edge film 5, which has approximately the thickness of the solar cell 6 and encloses the interconnected cells on all sides. After performing the Manufacturing process turns the loosely assembled components into a solid bond, as shown in Fig. 2b.
Aus Fig. 3, die einen sandwichartig lose zusammengefügten Verbund zeigt, geht hervor, daß allseitig ein von Solarzellen 6 freier Rand gelassen wird, in den eine Randfolie 5 eingelegt wird, die die Stärke der Solarzellen 6 aufweist.From Fig. 3, a sandwich-like loosely assembled composite shows, it can be seen that an edge free of solar cells 6 is left on all sides, into which an edge film 5 is inserted, which has the thickness of the solar cells 6.
Der so vorbereitete und fixierte Verbund durchläuft gemäß Fig. 4 dann das nachfolgend beschriebene Verfahren.The composite prepared and fixed in this way then passes through according to FIG. 4 the procedure described below.
Der Verbund 11 im linken Teil der Figur ist mit dem D#ichtungsring 7 mit Anschlußstutzen 12 versehen, der an ein Ring-Vakuum-System eines umlaufenden Transportbandes 13 angeschlossen ist. Die auf dem Band befindlichen vorgefertigten Solargeneratoren 11 durchlaufen einen Infrarot-Tunnel 14 oder eine konventionell aufgebaute Heizkammer mit einer vorbestimmten Geschwindigkeit. Hierbei wird der Verbund 11, je nach installierter elektrischer Leistung der Strahler, aufgeheizt. Der klebrig und zäh gewordene Schmelzkleber verbindet sich infolge des äußeren Luftandrucks sowohl mit den Scheiben als auch mit den Solarzellen zu einem sogenannten Vorverbund. Im Randbereich kommt es ebenfalls zu einer Verschmelzung der Randstreifenfolien und somit insbesondere zu einem Abdichten der evakuierten Spalte zwischen den Solarzellen. Nach Entfernen des elastischen Dichtringes 7 am Ende des Durchlaufs ist das Teil ohne weiteres hantierbar, da es in sich voll fixiert und außerdem als Generator voll betriebsfähig ist.The composite 11 in the left part of the figure is with the sealing ring 7 provided with connection piece 12, which is attached to a ring vacuum system of a rotating Conveyor belt 13 is connected. The prefabricated ones on the belt Solar generators 11 pass through an infrared tunnel 14 or a conventional one built-up heating chamber at a predetermined speed. Here the Compound 11, depending on the installed electrical power of the radiators, heated. The hot melt adhesive, which has become sticky and tough, bonds together as a result of the external air pressure both with the panes and with the solar cells to form a so-called pre-assembly. The edge strip films also fuse in the edge area and thus in particular to a sealing the evacuated column between the solar cells. After removing the elastic sealing ring 7 at the end of the The part can be handled without further ado as it is fully fixed in itself and is also fully operational as a generator.
Zur Erzielung eines lunker- und blasenfreien Verbundes, auch in den Zellenspalten, werden die Generatoren dann einem Autoklav-Prozeß unterworfen. Hierbei können typische Parameter für die Temperatur und den Druck gewählt werden, wobei das Temperatur-Druckprofil über etwa eine bis zwei Stunden gefahren werden kann. Bei dieser Temperatur wird der Kleber so niederviskos, daß der umgebende Druck ausreicht, um ihn in die Zellenspalte fließen zu lassen.To achieve a void-free and bubble-free bond, also in the Cell gaps, the generators are then subjected to an autoclave process. Here typical parameters for temperature and pressure can be selected, whereby the temperature-pressure profile can be run for about one to two hours. At this temperature the adhesive becomes so viscous that the surrounding pressure is sufficient to let it flow into the column of cells.
In Abwandlung des vorgeschriebenen Prozesses kann der Verbund auch einen Infrarottunnel durchlaufen, in dem eine höhere Klebertemperatur erreicht wird. Diese kann durch eine geringere Geschwindigkeit des Transportbandes, eine höhere installierte Leistung oder einen längeren Tunnel bei gleicher Geschwindigkeit erzi~elt werden. Hierbei verklebt der Verbund, wie in Figur 4 beschrieben, wobei der Kleber auch schon in die Zellenspalte fließt, so daß im Ergebnis ein klarer, blasenfreier Verbund erhalten wird.In a modification of the prescribed process, the network can also Pass through an infrared tunnel in which a higher adhesive temperature is reached. This can be increased by a lower speed of the conveyor belt installed power or a longer tunnel at the same speed will. Here, the composite adheres, as described in FIG. 4, with the adhesive already flows into the cell gap, so that the result is a clearer, bubble-free Composite is obtained.
Eine andere Möglichkeit besteht darin, die mit den elastischen Ringen versehenen und evakuierten Sandwiches in einen Autoklav einzubringen, und hier an ein internes Vakuumsystem anzuschliessen. Ist der Autoklav gefüllt, wird er aufgeheizt. Bei einem vorgegebenen Temperatur-Druckprofil schließen sich die Zellenspalten mit dem Kleber, wie bereits ausgeführt wurde.Another possibility is the one with the elastic rings placed and evacuated sandwiches in an autoclave, and here on to connect an internal vacuum system. When the autoclave is full, it is heated up. With a given temperature-pressure profile, the cell gaps also close the glue, as already stated.
Schließlich ist in Fig. 5 eine weitere Variante dargestellt, bei der der Solargenerator 11 ohne Gummiring auf dem Transportband 13 einen Infrarottunnel 14 durchläuft, in dem der Schmelzkleber aufgeheizt wird. Unmittelbar im Anschluß daran wird das Teil zwischen zwei Gummiwalzen 15 leicht gepresst derart, daß insbesondere der Randstreifen der Scfimelzkleberfolie mit dem Glas und den dazwischen befindlichen Folien tinuierlichen Verfahrens können die mit Dichtringen versehenen Sandwiches stationär in einen Wärmeofen eingelegt werden.Finally, in Fig. 5, a further variant is shown in which the solar generator 11 without a rubber ring on the conveyor belt 13 an infrared tunnel 14 runs through, in which the hot melt adhesive is heated. Immediately afterwards thereon the part is lightly pressed between two rubber rollers 15 in such a way that in particular the edge strip of the adhesive film with the glass and those in between Foils continuous process can be provided with sealing rings Sandwiches are placed stationary in a heating oven.
Auch hierbei verschmilzt der Kleber zu einem blasenfreien Verbund. Dieser stationäre Prozeß ist für kleinere S-tUckzahlen einfacher und kostengünstiger. In ähnlicher Weise lassen sich auch die Verf-ahrensvarianten, wie sie in Verbindung mit den Ausführungsbeispielen nach den Figuren 4 und 5 beschrieben wurden, zur Erzeugung kleinerer Stückzahlen abändern.Here, too, the adhesive fuses to form a bubble-free bond. This stationary process is simpler and cheaper for smaller numbers of pieces. In a similar way, the procedural variants, as they are in connection with the exemplary embodiments according to FIGS. 4 and 5 have been described for generation change smaller quantities.
dicht verschmilzt.fuses tightly.
Diese Teile werd-en wiederum einem Autoklavprozeß unterworfen.These parts are in turn subjected to an autoclave process.
Hierbei wird durch Druckanwendung der Schmelzkleber in die Zellenzwischenräume fließen, wobei die Luft aus den allseitig geschlossenen Zwischenräumen der Solarzelle in den Kleber diffundiert. Auch hier entsteht ein klarer, blasenfreier Verbund.The hotmelt adhesive is pushed into the spaces between the cells by applying pressure flow, with the air coming out of the interstices of the solar cell, which are closed on all sides diffused into the adhesive. Here, too, a clear, bubble-free bond is created.
Mit dem Autoklav-Verfahren lassen sich Solargeneratoren mit Flächen von 500 bis 5.000 m in einem ein- bis zweistündigen Prozeß erreichen. Die direkte Beschickung eines Autoklaven ergibt zwar einen Chargenbetrieb, der jedoch infolge der genannten Flächen aufgrund der dichteren Beschickung zu sehr viel groberen Stückzahlen führt als bekannte Verfahren zur Generatorherstellung. Die Herstellungskapazität für Generatoren läßt sich verfahrensabhängig einmal aus der vorgegebenen Breite des Durchlaufofens und der Durchlaufgeschwindigkeit bestimmen, zum anderen aber aus dem Kammervolumen des Autoklaven ableiten. Dabei ist nur die Auslegung von entscheidender Bedeutung.With the autoclave process, solar generators with surfaces Reach from 500 to 5,000 m in a one to two hour process. The direct one Charging an autoclave results in batch operation, but it does so as a result of the areas mentioned to much larger quantities due to the denser loading leads as a well-known process for generator production. The manufacturing capacity for generators, depending on the process, one can choose once from the specified width of the conveyor oven and the throughput speed, on the other hand derive from the chamber volume of the autoclave. The only thing that matters is the design Meaning.
Außer dem bisher beschriebenen sogenannten symmetrischen Verbund, d. h. zu beiden Seiten der Solarzellen befinden sich gleiche Bauelemente, läßt sich auch mit dem Verfahren nach der Erfindung ein sogenannter asymmetrischer Verbund herstellen. Hierunter ist ein Aufbau zu verstehen, bei dem eine der beiden Glasscheiben, zumeist die der# Sonne abgewandte, durch eine hochwertige, sehr witterungabestandige Folie ersetzt wird. Ein solcher Aufbau kann aus Gewichts- und Kostengründen zweckmässig sein. Bei einem derartigen Aufbau kann wegen der einen flexiblen Seite der die Dicke einer Solarzelle aufweisende Schmelzkleber-Randstreifen in Fortfall kommen.In addition to the so-called symmetrical composite described so far, d. H. The same components are located on both sides of the solar cells also with the method according to the invention a so-called asymmetrical composite produce. This is to be understood as a structure in which one of the two glass panes mostly the one facing away from the sun, due to a high-quality, very weather-resistant Foil is replaced. Such a structure can be expedient for reasons of weight and cost be. With such a structure, because of the one flexible side of the thickness a solar cell having hot-melt adhesive edge strips are no longer available.
