摘要:
In an apparatus for the transfer of substrates (9) from an initial station (3) through several process stations (4 to 8) and back to this initial station (3), manipulators (10 to 14) having pivoting gripper arms (15 to 19) and carousel transfer systems (20,21) for the transfer of the substrates (9) are provided. One of the carousels (20) provided with substrate holders (22) cooperates both with a two-armed first manipulator (11) and with a two-armed second manipulator (10). The second manipulator (10) lifts several substrates (9) simultaneously from the first carousel (20) in one period of time and feeds them to the corresponding second process station (5) which is configured for the simultaneous processing of several substrates. The second manipulator (11), in the same period of time, lifts one substrate (9) at a time from the first carousel (20) in several swings of its two gripper arms (16,16') and feeds them to the first process station (4) for the processing of one substrate at a time and carries them back from this process station (4) onto the first carousel (20). Two injection molding machines can be associated with the first carousel (20) and can feed the substrates directly through an additional manipulator.
摘要:
The invention describes a method and a device for introducing and removing substrates. Substrates (5) are transported into a lock (2) by a transport means (4). A collection container (3) is located in said lock below the substrates (5) for collecting possible substrate fragments (19). The substrates (5) are removed together with the collection container (3) and the lock cover (18) once the lock (2) has been flooded. The lock cover (18) and the collection container (3) form an almost closed box around the substrates (5). After the substrates (5) have been replaced and the collection container (3) has been emptied, the new substrates (5) are introduced together with the collection container. All the steps are carried out in the machine cycle to ensure an effective production process.

A first turntable (4) has a plurality of posts (6) equidistantly distributed and arranged in a circle on the turntable (4), wherein a plurality of substrates (7) can be stacked on each post (6). Stationary loading (9) and unloading stations (10 11) are provided and the distance between each pair of adjacent stations (9, 10, 11) corresponds to the distance between each pair of adjacent posts (6), the first turntable being rotated stepwise so that each post can be stopped successively at adjacent stations. A second turntable (12) is rotated stepwise through a loading station (15), a transfer station (16) and an unloading station (17). A loading arm transfers substrates from the loading station of the first turntable to the loading station of the second turntable, a transfer arm transfers the substrates from the transfer station to a coating station, and an unloading arm transfers coated substrates from the unloading station of the second turntable to either of the two unloading stations of the first turntable. A control system (33) includes a sensor (29), a counting device (30) and a servo motor (31), the servo motor (31) driving the unloading arm (21), the unloading station which receives a substrate being selected by the control system (33).

摘要:
The invention describes a device for transporting a substrate (5) into a working area (2, 3, 22) which can be temporarily separated in a vacuum-tight manner, and a corresponding method. A transport means (4) transports a substrate (5) in the plane (XY) to a defined working area (2, 3, 22) of a chamber (1). The transport means (4) has a deflectable sealing frame (6) which can be moved in a Z-direction perpendicular with respect to the XY-plane. The sealing frame (6) has two opposing sealing surfaces (10, 11) in the Z-direction. By pressing a closure means (16, 21, 24) against a first sealing surface (10, 11) and thus pressing the second sealing surface (11, 10) against a chamber wall (32, 31), the space of the working area (2, 3, 22) of the chamber (1) can be sealed.

Apparatus for transporting substrates to and from at least one device (1) for holding substrates (2), the at least one device having a substrate support (5) disposed in a vacuum chamber (4, 4', 4"). The apparatus includes at least one displaceably disposed gripper (75), which can be displaced by a mechanical and/or electro-magnetically or magnetically operating positioning device (130) between a substrate gripping position and a substrate release position, and a centering device (157, 157', 161) for centering a substrate relative to the substrate support in conjunction with transport of the substrate by the apparatus to the substrate support.
摘要:
A rotatable substrate holder (6) which has a plurality of substrate pickups in a circular arrangement at equal distances apart is disposed in a vacuum chamber (1). A corresponding number of substrates are driven stepwise on a circular path from an air lock station (8, 9) through at least one coating station (10, 11) to the air lock station. To increase the throughput of substrates, the vacuum chamber (1) has two air lock stations (8, 9) and two coating stations (10, 11) one following the other. The step size of the drive (36) on the one hand, and the angular position of each coating station (10 and 11, respectively) with respect to the air lock station associated with it (8 and 9, respectively) with reference to the axis of rotation of the substrate holder (6) on the other hand, are selected such that one and the same coating station (10 and 11, respectively), through the step-wise movement of a particular substrate pickup (63), is associated in each case with one and the same air lock station (8 and 9, respectively).
