Definitions
- the present invention relates to a device for curing the Leitklebertitle ist of metal strips on photovoltaic thin-film solar cells using thermal energy according to the preamble of claim 1.

- the curing of the adhesive is carried out in an oven, but this has various disadvantages, including the disadvantage that an over the entire length of intensive contact can not be guaranteed. Due to the substantially uniform temperature acting on all areas a controlled curing of the adhesive is not possible.
- Object of the present invention is therefore to provide a device for curing the Leitklebertitle ist of metal strips on photovoltaic thin-film solar cells of the type mentioned, which ensures a controlled curing of the adhesive and thus leads to a uniform over the entire length and surface contact.
- each photovoltaic thin-film solar cell is exposed in a controlled manner to a defined temperature and thus the conductive adhesive contact is cured.
- the defined temperature is thereby selectively supplied to that region of the solar cell at which the Leitkleberutton ist is located.
- the device is adjustable to that region of the solar cell, which is provided with the Leitkleberutton réelle.
- the features are provided according to claim 3, so that the device can be applied to different conductive adhesives, ie on the one hand in those which are cured by pure radiant heat and on the other hand in such conductive adhesives, which should be additionally cured under load.
- the heater is placed directly on the metal strip in question under slight pressure.
- the features according to claim 5 are provided, which means that heat can be supplied from both sides of the solar cells, so that the residence time for the curing process is reduced.
- the transport devices arranged therebetween are able to supply the solar cells for the curing process and then to continue to a further station.
- a structural design with regard to the adjustability and movability of the heating device results from the features according to claim 8.
- the features according to claim 9 are provided, so that over the length of the metal bands constant pressure is exerted on the conductive adhesive. It is expedient to provide the features of claim 10.

- a front cross member 38 and a rear cross member 39 is held movable up and down via hydraulic or pneumatic units 36, 37, which cross members 38 and 39 at their free ends in the associated corner pillars 27 and 28 and 29, respectively and 30 are vertically guided.
- the two cross members 38 and 39 are connected to each other by longitudinal members 41 and 42, on the underside of a heat radiation assembly 43 in the form of evenly spaced longitudinally disposed transverse infrared bodies 44 is arranged.
- Hydraulic or pneumatic units 46 to 49 are provided near the two cross members 38 and 39 near the two ends connected to the corner pillars, which are of identical design and whose cylinder body 51 are held transversely movable on the cross members 38, 39.
