Problems solved by technology
However, graphene is only composed of one layer of carbon atoms, and it can only exist stably under the condition of being closely attached to the substrate. At the same time, severe external conditions can easily destroy the graphene lattice and introduce defects, which seriously affect the performance of graphene.

[0032]The specific implementation method is: the controller 11 controls the first electromagnet 457 to drive the linkage sleeve 452 to rise, so that the graphene film is placed on the top of the storage plate 44, and then controls the first electromagnet 457 to drive the linkage sleeve 452 to descend, so that the graphite The alkene film is initially fixed, and then the lifting table 3 is started to raise the entire transmission assembly 4, and then the controller 11 controls the second electromagnet 68 to lose its magnetism. At this time, the elastic force of the pulling spring 65 and the compression spring 69 is used to pull the spool 66 instantly. Entering the first set of plates 61, at this time, the reaction potion acts on the top of the one-way valve 7, and the one-way valve 7 is opened in one direction. At this time, the copper foil outside the graphene film reacts with the potion, and the gas in the reaction process causes the one-way valve to The pressure inside 8 incr...

The invention discloses a graphene film transfer device, and particularly relates to the field of graphene film transfer, the graphene film transfer device comprises a bottom shell and a top shell, the side surfaces of the bottom shell and the top shell are clamped with each other, a one-way valve is formed between the bottom shell and the top shell, a separation plate is fixedly mounted at the top of an inner cavity of the top shell, and the separation plate is fixedly mounted at the top of the inner cavity of the top shell. An electromagnetic valve assembly and a one-way valve are sequentially and fixedly installed on the side face of the isolation plate from top to bottom, the side face of the electromagnetic valve assembly and the side face of the one-way valve are fixedly connected with the inner wall of the top shell, and a lifting table is fixedly installed on the bottom face of an inner cavity of the bottom shell. According to the device, graphene falling onto a silicon substrate is moved to the position above a transmission assembly by driving a conveying belt, and finally, a controller is matched with a micro hydraulic lifting rod and a distance sensor to guide a graphene film out of a bottom shell and a top shell through a balance plate according to the thickness of the graphene film; the whole driving outward moving process is accurately controlled by the controller, the fluctuation is low, and the stability is high.
Description
technical field [0001] The invention relates to the technical field of graphene film transfer, more specifically, the present invention relates to a graphene film transfer device. Background technique [0002] As we all know, graphene is a two-dimensional carbon nanomaterial composed of carbon atoms with sp2 hybrid orbitals in a hexagonal honeycomb lattice. Graphene has excellent optical, electrical, thermal and mechanical properties. Graphene has important application prospects in energy, biomedicine and drug delivery, and is considered to be a revolutionary material in the future. Due to its good thermal properties, graphene is now widely used in the field of electrothermal films. [0003] At present, the most mainstream preparation method of graphene is the chemical vapor deposition method, and people can directly grow graphene on Cu (copper), Ni (nickel) and other metal substrates. Although graphene can be grown on a metal substrate on a large scale by CVD, graphene oft...
