Embodiment Construction

[0029]FIG. 1 shows in a sloping or oblique view a reception device 11 which is constructed in the manner of a tray. Outside external frame pieces 12 and intermediate inside frame pieces 14 form a type of grid or lattice with recesses between them, so as to constitute reception zones 20. It can be seen that all the reception zones 20 between frame pieces 12 and 14 are of the same size, although this need not be the case.

[0030]On the rightwards-directed side is provided an angular section 16. Here the outside frame piece 12 is firstly bent upwards and then with a marginal strip 17 to the side again. The reception device 11 can be made from metal, particularly a sheet metal plate. It can be coated in insulating manner with a covering or a paint, which is resistant to the treatment media generally used during galvanizing. The marginal strip 17 is free on at least one side or has an electrically conductive surface, advantageously this is on both sides.

[0031]Particularly the larger scale ...

Abstract

In order to treat solar cells in an electroplating device, they can be inserted into a grid-like or tray-like picking-up device. They are thus mechanically held and electrical contact is made with them via contacts. Instead of individual solar cells, the picking-up devices are moved with a large number of inserted solar cells through the electroplating device for treatment. Electrical contact with the solar cells is in this case made via the contacts and the frame limbs on a projecting angle section together with edge strips of the pick-up. Contact rollers rest on the edge strips and are connected to an electrical power source.

Description

FIELD OF APPLICATION AND PRIOR ART[0001]The invention relates to a device for receiving or holding several flat substrates in one plane, as well as a galvanizing or electroplating device with a passage path for the substrates through a treatment chamber, the substrates being held in an aforementioned device.[0002]Hitherto substrates have been conveyed on conveying rollers lying in the manner of a roller conveyor in galvanizing devices for substrates, such as for example printed circuit boards or more especially solar cells or wafers. However, this can give rise to problems in the case of very sensitive substrates, such as for example thin solar cells. Here the substrates can be formed from very thin silicon, which is correspondingly sensitive or fragile. In addition, sensitive substrates have to be handled with extreme care, for example on introduction into a galvanizing device. In many cases this means either increased mechanical expenditure for the gripping devices or a decelerate...
