Abstract:
A device for producing a substrate composite consisting of two substrates bonded together with an intermediate bond layer; said device comprising:(a) first and second input stations (2â€³, 2â€², respectively) arranged on a circular arc (8), said input stations being spaced apart by an angular distance &agr; and each respectively supplying a respective one of a first and a second substrate (15â€³, 15â€²) for a first and a second substrate composite half, (b) at least first and second processing stations (5â€³, 5â€²) arranged on the circular arc (8), said processing stations being spaced apart by the angular distance &agr;, (c) first and second output stations (6â€³, 6â€², respectively) arranged on the circular arc (8), said output stations being spaced apart by the angular distance &agr;, for receiving the first and the second substrates, respectively, after processing, wherein the first output station (6â€³) comprises a device for turning the first substrate and placing it onto the second substrate, (d) a first transporting means (4) for transporting the first and second substrates on the circular arc (8) and comprising at least two grippers (11 and 12) which can be rotated on the circular arc through an angle &bgr;, wherein each of the grippers (11 and 12) transports a respective one of the first and second substrates from a respective input station (2â€³ and 2â€²) to a respective processing station (5â€³ and 5â€²) and to a respective output station (6â€³ and 6â€²), (e) a bonding station for bonding the first and second substrates with a bond layer disposed intermediate the first and second substrates to form a substrate composite, (f) a drying station (19) for curing the bond layer, (g) a turning station (22) for turning the substrate composite, (h) a test station (23) for testing the substrate composite, (i) an output station (24) for the substrate composite, and (j) a second transporting means (18) for transporting the substrate composite between the stations defined in clauses (e) to (i).
