Description

Stand der TechnikState of the art

Laminatoren verschiedener Bauart werden für die Herstellung einer unlösbaren Verbindung der einzelnen Elemente von Photovoltaik(PV)-Modulen, bestehend aus einer Deckschicht – meistens Glasscheibe –, einer Klebefolie meistens EVA-Folie, eines Systems von Photovoltaik-Zellen meistens Siliziumzellen (Si-Zelle), einer weiteren Klebefolie, EVA-Folie sowie einem Trägerelement, meistens TEDLAR-Folie insgesamt SANDWICHE's genannt, verwendet. Laminatoren sind Vorrichtungen in welchen unter Temperatur und einem bestimmten Druck/Unterdruck mindestens zwei Fügelemente miteinander verbunden werden wovon mindestens ein Element mit Klebematerial versehen bzw. selbstklebend, ist. Während der Laminierung werden die EVA-Folien, zwischen welchen die Photovoltaik-Zellen eingelegt sind, verschmolzen, umschliessen diese und verbinden sich (unlösbar) mit der Deck- und Trägerschicht zum sog. MODUL. Die zum Laminieren vorbereiteten SANDWICHES befinden sich auf einem Tisch welcher in den Laminator eingeschoben wird. Nachdem der Tisch seine Endposition im Laminator erreicht hat wird die Laminierkammer nach dichtem Abschluss entsprechend den verfahrenstechnischem Vorgaben evakuiert. Die Heizplatte (1) erwärmt die Kammer und den sich in der Laminierkammer befindlichen Tisch mit dem sich darauf befindlichen SANDWICH. Hierbei ist es von Bedeutung, dass die Folie an jeder Stelle des SANDWICHE's gleichzeitig und gleichmässig schmilzt, und die beim Schmelzen entstehenden Gase entweichen können, damit sich im Laminat keine Einschlüsse bilden. Hierzu ist es erforderlich, dass an jeder Stelle des SANWICHES gleiche Temperatur herrscht – Temperaturabweichungen zwischen Innenbereich und Randzonen von mehr als 3 bis 5°C können zu einer verminderten Laminierqualität führen.Laminators of various types are used for the production of a non-detachable connection of the individual elements of photovoltaic (PV) modules, consisting of a cover layer - usually glass - an adhesive film mostly EVA film, a system of photovoltaic cells mostly silicon cells (Si cell) , a further adhesive film, EVA film and a carrier element, mostly called TEDLAR film SANDWICHE's total used. Laminators are devices in which under temperature and a certain pressure / vacuum at least two Fügelemente be connected to each other, at least one element provided with adhesive material or self-adhesive, is. During lamination, the EVA films, between which the photovoltaic cells are inserted, fused, enclose and (inextricably) connect with the cover and carrier layer to the so-called. MODULE. The SANDWICHES prepared for lamination are on a table which is inserted into the laminator. After the table has reached its final position in the laminator, the laminating chamber is evacuated after tight sealing in accordance with the procedural specifications. The heating plate ( 1 ) heats the chamber and the table located in the laminating chamber with the SANDWICH located thereon. It is important that the film melts simultaneously and uniformly at each point of the SANDWICHE, and that the gases formed during melting can escape, so that no inclusions form in the laminate. For this, it is necessary that the same temperature prevails at each point of the SANWICH - temperature deviations between interior area and edge zones of more than 3 to 5 ° C can lead to reduced lamination quality.

Laminatoren üblicher Bauart wie sie zum Beispiel aus der DE 10 2007 034 135 A1 bekannt wurden, weisen unter anderem Heizplatten mit verschiedenen Heizungssystemen auf. Die Heizungssysteme werden unterschieden je nach Art in Elektro-, Dampf- und Thermoölheizung. Die bekannte Bauart der Heizplattensysteme erfüllt meistens nicht die Anforderungen einer einwandfreien gleichmässigen Schmelzung der Klebefolie in möglichst kurzer Zeit, da die Randbereiche naturgemäß kühler sind und daher mehr Wärmemenge benötigen.Laminators of conventional design such as those from the DE 10 2007 034 135 A1 have been known, among other heating plates with different heating systems. The heating systems are differentiated depending on the type in electric, steam and thermal oil heating. The known type of Heizplattensysteme usually does not meet the requirements of a perfect uniform melting of the adhesive film in the shortest possible time, since the edge regions are naturally cooler and therefore require more heat.

Mit der Erfindung nach Anspruch 1 werden die Nachteile der bisherigen Systeme gelöst. 1 zeigt ein Beispiel zur gleichmäßigen Ausbildung eines Temperaturprofils über die gesamte Laminierfläche. Dazu werden die Heizplatten (1) mit verschiedenen Kreislaufsystemen (3) und (4) mit unterschiedlichen Heizkanalquerschnitten (5) und (6) versehen, die von voneinander getrennten Heizkreislaufsystemen (3) und (4) versorgt werden. Die Steuerung der Heizkreislaufsysteme (3) und (4) erfolgt über die Steuerung der Regelventile (8) und damit der zugeführten Wärmemenge in Abhängigkeit der Temperatur an den Messstellen (2) an verschiedenen Punkten in der Heizplatte (1) sowie einer Steuerung (7) der zugeführten Oeltemperatur und Oelmenge.With the invention according to claim 1, the disadvantages of the previous systems are achieved. 1 shows an example for the uniform formation of a temperature profile over the entire lamination. For this purpose, the heating plates ( 1 ) with different circulatory systems ( 3 ) and ( 4 ) with different Heizkanalquerschnitten ( 5 ) and ( 6 ) provided by separate heating circuit systems ( 3 ) and ( 4 ) are supplied. The control of the heating circuit systems ( 3 ) and ( 4 ) via the control of the control valves ( 8th ) and thus the amount of heat supplied as a function of the temperature at the measuring points ( 2 ) at various points in the heating plate ( 1 ) and a controller ( 7 ) of the supplied oil temperature and oil quantity.
