Problems solved by technology

[0003] Due to the excellent performance of graphene, graphene has become a key point to break through the bottleneck of today's scientific and technological development. Although my country ranks among the top in the world in the research of graphene papers, there are still many deficiencies in the application and detection of graphene. In the application of graphene, whether multi-layer graphene meets the requirements of use during the overlapping process requires good detection methods and detection equipment

specific Embodiment 2

[0073] According to the control system of the multilayer graphene stain location detection device of embodiment 1, comprising:

[0074] control units, including controllers;

[0075] Scanning unit, comprises scanning mechanism 5, and scanning mechanism 5 comprises laser device, lifter, and laser device comprises a flat laser generator, a round head laser generator and concave laser receiving groove, and is located at some laser sensors inside the laser receiving groove ; After the laser lifts to the specified position, the ribbon laser produces a flat laser with a width of 1mm and a thickness of 10um. The laser is reflected by the graphene and is received by the laser sensor in the specified area in the laser receiving slot; When the laser intensity change received by the laser or the laser sensor in the designated area exceeds the set value, the round head laser generator is turned on to generate a cylindrical laser with a radius of 10um. The cylindrical laser scans along the...

Abstract

The invention relates to a multilayered graphene stain positioning detection device. The multilayered graphene stain positioning detection device comprises a rack, and a scanning mechanism, a controller, an operation mechanism, a photographing mechanism, an image processor, a sealing cover, an air blower and a vacuumizing device which are arranged on the rack; stains on graphene are detected by using the laser refraction principle, and positions which possibly have the stains can be detected by the scanning device and are photographed; a high-definition camera is used for zooming in and focusing, so that the pertinence is relatively strong and errors are reduced; meanwhile, different colors are used as backgrounds so that a situation that the stains are not easy to find when the single background is used is reduced, and the working amount can be reduced in a determined region; then, regions which possibly have the stains are observed overall because the stains with a continuous relation are easy to observe by naked eyes and do not need to be judged by adopting the method; collected photos have relatively high accuracy; different light sources are adopted so that the influences of the light sources on results are reduced.

Description

Technical field [0001] The present invention involves a multi -layer graphne staining positioning detection device. Background technique [0002] Graphene is a two -dimensional crystal that is peeled from graphite materials and consisting of carbon atoms with only one layer of atomic thickness.Graphene is both the thinnest material and the strongest material. It is 200 times higher than the best steel.At the same time, it has good elasticity, and the stretching range can reach 20%of its size.If a piece of graphene with an area of 1 square meter is made into a suspension, it can withstand a cat of one thousand grams of cats less than 1 mg.Graphene is almost completely transparent and only absorbs 2.3%of the light.On the other hand, it is very dense, and even the smallest gas atom cannot penetrate.These features make it very suitable as raw materials for transparent electronic products, such as transparent touch display, luminous boards and solar panels. [0003] Due to the excelle...
