Description

Technical Field

[0001] This invention belongs to the field of laser-induced graphene technology, specifically a laser-induced biomass-based graphene device. Background Technology

[0002] Graphene, as an emerging two-dimensional nanomaterial, has been widely used in various fields due to its unique physical structure and chemical properties. Laser-induced graphene technology can prepare graphene materials from carbon-containing biomass materials that are widely available in nature in a low-cost, environmentally friendly, and faster manner.

[0003] Laser-induced biomass-based graphene devices are used to convert biomass materials into graphene. Utilizing the high energy density of a laser, it is focused onto the surface of the biomass material, inducing the breakdown of chemical bonds between carbon and other elements (such as oxygen, nitrogen, and hydrogen). During this process, carbon atoms rearrange to form graphene with a tightly packed honeycomb structure, while the other element atoms evaporate under high-temperature conditions.

[0004] In the production of graphene, the carbon source is brought under the laser to generate the graphene layer through laser thermal effect. However, due to the limited travel of the laser, its scanning range is limited, which is not convenient for mass production of graphene. Furthermore, when the carbon source is scanned by the laser, some of the carbon source may detach from the scanning stage under the action of the high energy of the laser, which is not convenient for the carbon source to be sorted later. Therefore, a laser-induced biomass-based graphene device is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-5This utility model provides a laser-induced biomass-based graphene device, including a processing box 1. The processing box 1 is made of high-quality steel and is sealed. A sealed door 2 is hinged to the front of the processing box 1 to improve its sealing performance. An electric slide 3 is installed at the top inside the processing box 1. An electric slide 4 is slidably connected to the electric slide 3. A laser body 5 is slidably connected to the electric slide 4 to control the lateral movement of the laser body 5. The laser body 5 is a pulsed laser, which can precisely control the degree of graphitization and reduce thermal damage. A batch conveying mechanism is installed inside the processing box 1 to batch laser-induce carbon sources. The batch conveying mechanism includes a motor 6 installed at the bottom inside the processing box 1. The output end of the motor 6... The system includes a detachable support plate 7 with multiple side arms 8 evenly distributed on it. A scanning stage 9 is detachably mounted at the end of each side arm 8. The scanning stage 9 is compatible with the laser body 5. A carbon source processing mechanism is installed on the scanning stage 9. This mechanism prevents some carbon sources from detaching from the scanning support plate 11 under the high energy of the laser during laser scanning, facilitating subsequent carbon source preparation. An auxiliary mechanism is located on the upper inner side of the processing box 1. This mechanism smooths the carbon source on the scanning support plate 11, improving the laser-induced graphene effect. A gas supply mechanism is located on the side of the processing box 1. This mechanism allows gas to be introduced to suppress oxidation or regulate the product structure, ensuring the normal operation of laser-induced graphene.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, the carbon source processing mechanism includes a trough 10 opened on the scanning stage 9. A scanning support plate 11 is detachably installed in the middle of the inner side of the trough 10. A discharge trough 12 is opened at the bottom of the scanning stage 9. A trough plate 13 is detachably installed in the discharge trough 12 to prevent some carbon source from detaching from the scanning support plate 11 under the action of high laser energy, thereby facilitating the subsequent processing of carbon source.

[0030] Furthermore, such as Figure 4 As shown, multiple insertion holes 14 are evenly provided at the bottom of the scanning stage 9, and multiple insertion posts 15 are fixedly provided below the scanning support plate 11. The corresponding insertion holes 14 and insertion posts 15 are adapted to each other, so that the scanning support plate 11 can be quickly installed on the scanning stage 9.

[0031] Furthermore, such as Figure 2 and Figure 5 As shown, the auxiliary mechanism includes an electric push rod 16 located on the upper inner side of the processing box 1. A bracket 17 is fixedly installed below the electric push rod 16. A flat scraper 18 is installed below the bracket 17. The flat scraper 18 is positioned corresponding to the scanning support plate 11 and smooths the carbon source on the scanning support plate 11 to improve the laser-induced graphene effect.

[0032] Furthermore, such asFigure 1 As shown, the gas supply mechanism includes a vacuum pump 19 fixedly installed on the side of the processing chamber 1, a high-pressure nitrogen tank 20 detachably installed on the side of the processing chamber 1, a gas pipe 21 installed on the high-pressure nitrogen tank 20, a gas pressure control valve 22 installed on the gas pipe 21, and the other end of the gas pipe 21 connected to the processing chamber 1. Through the structure of the gas supply mechanism, gas can be introduced to suppress oxidation or regulate the product structure, ensuring the normal progress of laser-induced graphene. The gas pressure control valve 22 controls the flow rate of nitrogen in the high-pressure nitrogen tank 20 and inputs nitrogen into the processing chamber 1 as a protective gas to suppress oxidation or regulate the product structure, ensuring the normal progress of laser-induced graphene.

[0033] Furthermore, such as Figure 1 As shown, a barometer 23 is installed on the side of the processing box 1 to facilitate monitoring of the air pressure in the processing box 1.

[0034] Working principle: Through the structure of the batch conveying mechanism, carbon sources can be laser-induced in batches. The carbon source to be processed is placed on the scanning support plate 11. By driving the motor 6, the support plate 7 is rotated. The side arm 8 of the support plate 7 sequentially sends the scanning stage 9 to the bottom of the laser body 5. With the help of the electric slide 4, it moves on the electric slide 3. The laser body 5 uses laser thermal effect to generate graphene layer from the carbon source, which facilitates the batch scanning and production of graphene.

[0035] Through the structural design of the gas supply mechanism, gas can be introduced to suppress oxidation or regulate the product structure, ensuring the normal progress of laser-induced graphene. By controlling and adjusting the operation of the vacuum pump 19 and the pumping rate of the vacuum pump 19, the carbon source placement on the scanning support plate 11 is avoided. The processing box 1 is evacuated to a vacuum. Then, the flow rate of nitrogen in the high-pressure nitrogen tank 20 is controlled by the pressure control valve 22 to avoid affecting the carbon source placement on the scanning support plate 11. Nitrogen is then introduced into the processing box 1 as a protective gas to suppress oxidation or regulate the product structure, ensuring the normal progress of laser-induced graphene. Furthermore, a pressure gauge 23 is installed on the side of the processing box 1 for easy monitoring of the gas pressure in the processing box 1.

[0036] By using the structure of the auxiliary mechanism, the carbon source on the scanning support plate 11 is smoothed to improve the laser-induced graphene effect. By controlling the operation of the electric push rod 16, the support 17 is pushed so that the flat scraper 18 below the support 17 moves down to a suitable position. The flat scraper 18 smooths the carbon source that passes through the scanning support plate 11 in turn, so that it can fall into the gap groove between the scanning support plate 11 and the scanning stage 9.

[0037] By designing the carbon source processing mechanism, some carbon sources can be prevented from detaching from the scanning support plate 11 under the high energy of the laser during laser scanning. This facilitates subsequent cleaning of the carbon sources. The scanning support plate 11 is quickly installed on the scanning table 9 by inserting the pin 15 below the scanning support plate 11 into the insertion hole 14. When the carbon source on the scanning support plate 11 is laser-processed, some carbon sources will slide into the gap groove between the scanning support plate 11 and the scanning table 9 under the high energy of the laser. After the carbon source laser processing is completed, the scanning support plate 11 is removed from the scanning table 9, and then the trough plate 13 on the discharge trough 12 is removed to collect and clean the carbon sources that have fallen into the trough 10.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
