Abstract: The device for securing electrical, prefabricated connecting parts such as solder points, solder contacts or plug connectors on uniform or curved panes (1), comprises a position recognition mechanism (3), a pane reception table with mountings, means for moving the panes in x and y-direction of a coordinate system lying in the pane plane, means (9) for the reception of the connecting parts to be fastened, a roll-up closure (8) for the protection of laser light, a mechanism for reception and turning the pane, and an adjustable laser soldering head (4) arranged on the reception means. The device for securing electrical, prefabricated connecting parts such as solder points, solder contacts or plug connectors on uniform or curved panes (1), comprises a position recognition mechanism (3), a pane reception table with mountings, means for moving the panes in x and y-direction of a coordinate system lying in the pane plane, means (9) for the reception of the connecting parts to be fastened, a roll-up closure (8) for the protection of laser light, a mechanism for reception and turning the pane, and an adjustable laser soldering head (4) arranged on the reception means. The uniform or curved panes have contact area formed by screen-printing in a thick film technique. The reception means are freely fixable in the x-y plane on or over the pane reception area. The reception means allow the entrance of the laser light into the area of the solder joint. Suction devices adjustable in z-direction are intended at the reception table for holding the panes during the soldering procedure. The position of the contact areas or suitable marking points scans in contact-less manner. The suction devices adjustable in Z-direction are arranged on a co-ordinate table (2) adjustable in XY direction. The pane supports itself opposite to the reception table on a height-adjustable ball reception. The closure is adjustable in X or Y-direction to ensure a fine positioning of the pane. The pane is pressed over a conveyor against two x-closures and over an adjustment cylinder against the y-closure. The adjustment for the fine positioning takes place with the help of an optical measurement of markings and/or the contact areas on the pane. A mechanism is present laterally to the conveyor for receiving and placing the respective connecting parts in the reception means or directly on the pane and in the contact surface. The laser soldering heads are arranged above the pane. The turning mechanism has a camera as the position recognition mechanism, which detects both the position of the pane and the arrangement of the contact areas or markings. An independent claim is included for a procedure for securing electrical, prefabricated connecting parts such as solder points, solder contacts, or plug connectors on uniform or curved panes e.g. vehicle panes.
