▎ 摘　　要

NOVELTY - Graphene comprises a table body (1), where the table body is fixedly connected with an operation platform (2). The table body and the bottom plate (12) are hinged with two pull rods (16) and two annular blocks (14) and a bidirectional screw rod (15). Each of the pull rods is hinged to the corresponding annular block. The ring-shaped block is connected with the bidirectionally threaded screw rod. USE - Semiconductor preparation graphene used in modern electronic industry, transistor, integrated circuit and core material of various electronic elements, along with development of semiconductor technology, traditional silicon, performance lifting space of germanium and other element semiconductor. ADVANTAGE - The graphene is convenient and fast to clean on the particulate matter platform and impurity cleaning, and saves time and labor, so as to improve the cleaning efficiency. The first inner rod and the locating rod are matched with each other, under the condition of not needing manual cleaning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the device for preparing the graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a front structure schematic graphene of a semiconductor preparation device. 1Stage 2Operation platform 3Adjusting plate 4Air inlet pipe 5Connecting pipe 6Dust collecting chamber 7Mounting block 8Dust filtering net 9Limiting block 10Second handle 11Storage box 12Bottom plate 13Supporting base 14Annular block 15Bidirectional screw rod 16Pull rod 17First handle 18Second outer tube 19Limiting rod 20Second inner rod 21First inner rod 22Locating rod 23Connecting block 24First servo motor 25Dust board
