A modular-construction vacuum-coating system includes a plurality of functional chambers arranged one behind the other along a longitudinal extent in which substrates are moved through the chambers in a substrate-transporting region. To lower the production-related and installation-related outlay involved in supplying media, a functional chamber, as a first sub-module, is arranged in a first module and provided with an outer interface which is the same for at least a second module.
摘要:
In a transport device, which comprises at least one endless conveyor guided around at least two guide rollers, a monitoring appliance for monitoring motion of a guide roller is positioned on at least one of the guide rollers. The monitoring appliance comprises a first contact element disposed on and electrically connected with the guide roller, and a second contact element disposed near the guide roller. The first and second contact elements are arranged relative to one another in such a way that an electrical contact between them occurs with every revolution of the guide roller, such that the electric potential of the guide roller is transmitted to the second contact element. Additionally, a substrate treatment apparatus comprising such transport device is disclosed.
摘要:
A vacuum coating unit having a pair of side by side transport devices for transporting substrates in a transport direction. Each transport device includes at least one first endless conveyor running in the transport direction and having a conveying element guided around at least two guide rollers or pulleys. The conveying element is located at a distance from a guide device extending in the transport direction parallel to the conveying element in such a way that the ends of the substrates can be introduced into the gap between the conveying element and the guide device of the transport devices and can be moved in the transport direction by the displacement of the conveying elements.
摘要:
A transport device for transporting elongated substrates through a vacuum coating system comprises an essentially rectangular frame and two groups of holding elements, which are rotatably mounted on opposite sides of the frame in such a manner that any pair of opposite holding elements can be connected to both ends of a substrate. Furthermore, at least one retainer bar is provided that is operatively connected to a group of holding elements in such a manner that the holding elements of this group are moveable in order to increase or decrease by choice their distance from the holding elements of the other group. Also provided are a loading and unloading device for loading and unloading the transport device, and a method for loading and unloading the transport device.

摘要:
In a vacuum coating installation to coat planar substrates, comprising a vacuum chamber and a transport device arranged in the vacuum chamber for transporting the substrates along a transportation path through the vacuum chamber, with the transport device comprising a multitude of transport rollers arranged successively along the transportation path, each transport roller is adapted to be mounted at least at two different positions, vertically distanced from each other. A carrier frame has a substrate accepting structure and a guiding rod arranged at the bottom of the carrier frame in the direction of transportation to create a friction connection with the transportation device, connected to the carrier frame at the connection points, with the guiding rod being connected at least at one connection point to the carrier frame such that a relative displacement is possible of the guiding rod relative to the carrier frame in the direction of transportation.
