Method for bonding large modules (30, 31, 33), characterised by the following steps: - a large module (30, 31, 33) is fed to a bonder (1, 2, 3, 4, 5) from behind in a loading plane by means of a feed unit; - the large module (30, 31, 33) is handed over from the feed unit to a first transverse conveyor unit and transferred by said unit into a first buffer position provided in the bonder (1, 2, 3, 4, 5), the first buffer position being provided in a loading plane of the bonder (1, 2, 3, 4, 5); - the large module (30, 31, 33) is transferred from the first buffer position into a first handover position, where it is handed over to a vertical conveyor unit, in the loading plane by means of the first transverse conveyor unit; - by means of the vertical conveyor unit, the large module (30, 31, 33) is displaced vertically and transferred into a bonding plane, the large module (30, 31, 33), in the bonding plane, being located at least in portions in a working region of the bonder (1, 2, 3, 4, 5); - the large module (30, 31, 33) is processed by a first bonding head (15, 19) and optionally additionally by a second bonding head (15, 19), electrically conductive bonding connections being produced at the module (30, 31, 33); - the large module (30, 31, 33) is displaced vertically out of the bonding plane into a second handover position by the vertical conveyor unit, and in the second handover position handed over to a second transverse conveyor unit, the second handover position being provided in an unloading plane of the bonder (1, 2, 3, 4, 5); - the large module (30, 31, 33) in the unloading plane is transferred into a second buffer position by the second transverse conveyor unit; - the large module (30, 31, 33) is handed over to a removal unit from the second buffer position by means of the second transverse conveyor unit. - a large module (30, 31, 33) is fed to a bonder (1, 2, 3, 4, 5) from behind in a loading plane by means of a feed unit; - the large module (30, 31, 33) is handed over from the feed unit to a first transverse conveyor unit and transferred by said unit into a first buffer position provided in the bonder (1, 2, 3, 4, 5), the first buffer position being provided in a loading plane of the bonder (1, 2, 3, 4, 5); - the large module (30, 31, 33) is transferred from the first buffer position into a first handover position, where it is handed over to a vertical conveyor unit, in the loading plane by means of the first transverse conveyor unit; - by means of the vertical conveyor unit, the large module (30, 31, 33) is displaced vertically and transferred into a bonding plane, the large module (30, 31, 33), in the bonding plane, being located at least in portions in a working region of the bonder (1, 2, 3, 4, 5); - the large module (30, 31, 33) is processed by a first bonding head (15, 19) and optionally additionally by a second bonding head (15, 19), electrically conductive bonding connections being produced at the module (30, 31, 33); - the large module (30, 31, 33) is displaced vertically out of the bonding plane into a second handover position by the vertical conveyor unit, and in the second handover position handed over to a second transverse conveyor unit, the second handover position being provided in an unloading plane of the bonder (1, 2, 3, 4, 5); - the large module (30, 31, 33) in the unloading plane is transferred into a second buffer position by the second transverse conveyor unit; - the large module (30, 31, 33) is handed over to a removal unit from the second buffer position by means of the second transverse conveyor unit.
