Abstract:
1. A mounting device for disk-shaped substrates with at least one comb-like holder ( 1 ) having an elongated web ( 3 ), on which along the longitudinal extension (X-axis) thereof arranged at equal distances from each other are provided, which relative to the longitudinal extension of the web ( 3 ) protrude perpendicularly (Z-axis) over a uniform height and exhibit an identical total depth t ges corresponding to the width of the elongated web perpendicular (Y-axis) to the plane formed by the X and Z axis, wherein between the surfaces of neighboring comb elements ( 4 ) facing each other at least one recess ( 5 or 6 ) for the solar wafer ( 2 ) to be mounted is formed with an outer contour (u A ), the middle axis (A) of which runs in the direction of the Z-axis, and which exhibits a contact surface ( 7 ) and a guiding surface ( 8 ), which are arranged relative to each other and parallel to the middle axis (A) of the recess ( 5 or 6 ), for the solar wafer ( 2 ) to be mounted in the recess ( 5 or 6 ), characterized in that, a mounting gap ( 9 ) is provided between the respective neighboring comb elements ( 4 ) of the elongated web ( 3 ) of the at least one comb-like holder ( 1 ), the outer contour (u S ) of which comprises the contact surface ( 7 ) and guiding surface ( 8 ) for the solar wafer ( 2 ) to be accommodated in the mounting gap ( 9 ), formed in the direction of the X-axis with an arbitrary width (b H ) by two recesses ( 5 and 6 ) offset relative to each other in the direction of the X-axis, which have an outer contour (u A1 or u A2 ), and a respective depth (t 1 ) or (t 2 ) smaller than the total depth (t ges ) of each comb element ( 4 ), wherein the depth (t 1 ) and the depth (t 2 ) form the respective total depth (t ges ) of each comb element ( 4 ), and the outer contour (u A1 or u A2 ) has a groove ( 10 ) on the web side with a slanted surface section ( 11 ) on the web side that is located in a plane ( 12 ) running in an inclined manner at an acute angle (α) relative to the plane ( 13 ) of the contact surface ( 7 ) of the outer contour (u S ) of the mounting gap ( 9 ) such that the solar wafer ( 2 ) to be introduced into the mounting gap ( 9 ), when its lower edge ( 21 ) engages with the slanted surface section ( 11 ) of the groove ( 10 ) of the outer contour (u A1 or u A2 ), is to be glidingly shifted thereon into a predetermined position under the force of gravity while overcoming static friction, in which the solar wafer ( 2 ), upon rotating the comb-like holder ( 1 ) around a predetermined acute angle (φ) relative to the vertical line on the contact surface ( 7 ) of the outer contour (u S ) of the mounting gap ( 9 ), is brought with its surface ( 13 ) facing the latter in planar contact on the contact surface ( 7 ), and in which there is simultaneously provided a tolerance ( 14 ) between the surface ( 22 ) of the solar wafer ( 2 ) facing away from the contact surface ( 7 ) and the guiding surface ( 8 ) of the outer contour (u S ) of the mounting gap ( 9 ) running parallel to the contact surface ( 7 ).
