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 1

[0046] like figure 1 As shown, a multi-layer graphene stain photographing detection device of the present invention comprises: a frame 1 and a scanning mechanism 5 arranged on the frame 1, a controller, an operating mechanism, a photographing mechanism 3, an image processor, a sealing cover 7. Blowers and vacuum cleaners;

[0047] The scanning mechanism 5 includes a scanning frame, a laser and a lifter fixed on the scanning frame. The laser includes a flat laser generator, a round-head laser generator and a concave laser receiving slot, and a number of laser sensors are arranged inside the laser receiving slot; The sensor, the two laser generators and the lifter are respectively electrically connected with the controller;

[0048] The operating mechanism includes a mobile platform 2 and a fixture, a reflector and a light screen 6 arranged on the mobile platform 2. The mobile platform 2 is provided with a lateral shifter and a vertical shifter, and the mobile platform 2 and th...

specific Embodiment 2

[0061] According to the control system of the multi-layer graphene stain photographing detection device of embodiment 1, comprising:

[0062] control units, including controllers;

[0063] The scanning unit includes a scanning mechanism 5, the scanning mechanism 5 includes a laser, a lifter, and the laser includes a flat laser generator, a round-head laser generator, a concave laser receiving slot, and several laser sensors arranged inside the laser receiving slot ; After the laser is lifted to the designated position, the flat laser generator generates a strip-shaped laser with a width of 1 mm and a thickness of 10 μm. The laser is reflected by the graphene and received by the laser sensor in the designated area of ​​the laser receiving slot; the laser in the non-designated area is received. When the sensor receives laser light or the laser intensity change in the designated area exceeds the set value, the round head laser generator is turned on to generate a cylindrical lase...

specific Embodiment 3

[0070] The photographing method of the control system according to the specific embodiment 2:

[0071] (1), after the control unit marks the stain position, turn on the light screen 6 and the camera; adjust the light screen 6 and the camera position, so that the camera is aligned with the stain position of the graphene, and the light screen 6 reflected by the mirror is used as the background;

[0072] (2) Adjust the telescopic device and control the movement of the magnifying glass, so that the camera can focus on the stain position;

[0073] (3) Adjust the light screen 6 to a white screen, and the camera continuously takes pictures of the stain position at an interval of 0.1ms; obtain 20-30 photos;

[0074] (4) The photographing unit transfers the acquired photos to the control unit, and the control unit performs judgment processing;

[0075] (5) Adjust the color of the light screen 6 more than three times, take pictures of the stain position continuously each time and obtai...

Abstract

The invention relates to a multilayer graphene stain photographing detection device. The multilayer graphene stain photographing detection device comprises a stander, and a scanning mechanism, a controller, an operation mechanism, a photographing mechanism, an image processor, a seal cover, an air blower and a vacuumizing device, which are arranged on the stander; a camera is a high-definition camera and can photograph an object which is magnified for 500 times to 100 times, the camera has a continuous capture mode and can instantaneously take a plurality of pictures. Due to the photographing method, a position detected by a scanning unit and having a stain can be photographed, the high-definition camera is used for magnifying and focusing, the pertinence is higher, the position shape of the stain can be displayed in a more intuitive way, errors are reduced by virtue of multiple pictures way, and are gradually eliminated, different colors are used as a background, so that the situation of the single background that the stain is unlikely to discover can be reduced, and the precision is improved.

Description

technical field [0001] The invention relates to a multi-layer graphene stain photographing detection device. Background technique [0002] Graphene is a two-dimensional crystal that is only one atomic thick and consists of carbon atoms exfoliated from a graphite material. Graphene is both the thinnest material and the toughest, with a breaking strength 200 times higher than the best steel. At the same time, it has good elasticity and can stretch up to 20% of its own size. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it can withstand a cat of 1 kilogram with its own weight of less than 1 milligram. Graphene is almost completely transparent, absorbing only 2.3 percent of light. On the other hand, it is so dense that even the smallest gas atoms cannot penetrate it. These characteristics make it ideal as a raw material for transparent electronics, such as transparent touch displays, light-emitting panels, and solar panels. [0003] Due ...
