Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to PVD equipment, in particular to a novel substrate rack. Background Art
[0002] PVD physical vapor deposition technology refers to the technology of using physical methods under vacuum conditions to vaporize the surface of the material source (solid or liquid) into gaseous atoms or molecules, or partially ionize it into ions, and deposit a thin film with certain special functions on the surface of the substrate through a low-pressure gas (or plasma) process. Physical vapor deposition is one of the main surface treatment technologies.
[0003] After massive searches, it was found that the prior art publication number is CN210367893U, which discloses a substrate rack for physical vapor deposition coating equipment, and relates to the technical field of vacuum coating equipment. The substrate rack includes a substrate rack body and an ejector mechanism. The substrate rack body is a vertically arranged square frame structure. At least one clamp assembly is installed on both sides of the substrate rack body for fixing the glass plate. The clamp assembly is provided with a functional hole. The ejector mechanism is located on one side of the substrate rack body, and is arranged one-to-one with the clamp assembly. The output end of the ejector mechanism is arranged corresponding to the functional hole, and is used to control the clamp assembly to fix the glass plate. The substrate rack of the utility model inserts the ejector mechanism into the functional hole and realizes the fixing and loosening of the clamp assembly by moving it in the functional hole. It has high accuracy and low wear. It can accurately and stably control the clamp assembly to ensure the stability and accuracy of the upper and lower glass sheets of the substrate rack.
[0004] At present, in the vacuum sputtering coating production line, the existing continuous vacuum coating device generally includes a plurality of vacuum chambers connected in sequence, and a transmission device is arranged at the bottom of the vacuum chamber; usually the transmission device carries an upright substrate rack for fixing the substrate, and the substrate rack is provided with insulating components, and these insulating components are generally provided with protective covers; however, in actual application, since the protective covers mostly protrude from the surface of the substrate rack, in the process of conveying the substrate, it will affect the uniformity of the film layer due to being too protruding from the surface of the substrate rack, and it is easy to cause a short circuit between the substrate and the cavity.
[0005] On the other hand, the substrate rack is provided with locking components for fixing the substrate, and these locking components are tightly in contact with the edge of the substrate; however, in actual application, since most of the locking components protrude from the surface of the substrate rack, during the process of conveying the substrate, the substrate may be damaged due to protruding too much from the surface of the substrate rack.
[0006] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a new type of substrate rack to make it more valuable for industrial use. Utility Model Content
