NOVELTY - The method involves welding a device shell (1) with a servo motor. An output end of the servo motor is connected with a one-way threaded rod (3). The one-way threaded rod is movably connected with a placing plate (4). The placing plate is slidingly connected on the device shell. The placing plate is connected with a fixing pipe. The fixing pipe is internally limited and slidingly connected with a rubber piston. The rubber piston is connected with a bracket (5) by a bolt. The bracket is glidingly connected in a sealing ring that is connected with a top end of the fixing pipe, where the device shell is provided with a hydraulic cylinder (18). USE - Graphene plate processing method. ADVANTAGE - The method enables glidingly connecting the bracket in the sealing ring that is connected with the top end of the fixing pipe and extracting air in a rubber sucker of a top unit connecting pipe for stably absorbing and fixing a graphene plate so as to effectively prevent a graphene plate position deviation in a grinding process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene plate processing system. Device shell (1) One-way threaded rod (3) Placing plate (4) Bracket (5) Hydraulic cylinder (18)
