[0001] The invention belongs to the technical field of graphene preparation equipment, and in particular relates to a graphene material stripping device and a method for stripping graphene. Background Art

[0002] As a new type of two-dimensional material, graphene has extremely high electrical conductivity, thermal conductivity, mechanical strength and chemical stability, and is widely used in electronics, optoelectronics, energy storage and other fields. However, since graphene exists in graphite in its natural state, how to efficiently and stably peel off single-layer or few-layer graphene has become a key technical problem.

[0003] At present, the graphene exfoliation methods mainly include mechanical exfoliation, chemical vapor deposition (CVD), liquid phase exfoliation and electrochemical exfoliation. The mechanical exfoliation method, also known as the tape method, can obtain high-quality single-layer graphene. When preparing graphene in the laboratory, the tape method is the best method for obtaining single-layer graphene, and can obtain the required single-layer graphene in the fastest and easiest way.

[0004] When using the tape method to produce single-layer graphene, a specific tape needs to be tightly attached to a graphite block. When the tape is torn off, a portion of the graphite on the surface of the graphite block will adhere to the tape. A new tape is then used to repeatedly tear off the graphite on the original tape, and finally a single-layer graphene is obtained.

[0016] The above technical solution includes the following steps:

[0017] S1. Adhere the initial graphite sheet to the base tape;

[0018] S2. The top ends of the two brackets are brought close to each other so that the rubber roller and the pressure roller face each other and the rubber roller and the pressure roller are in close contact with the peeling tape;

[0019] S3. The lifting mechanism and the first motor are started, and the lifting mechanism drives the peeling tape to descend while the rubber roller drives the base tape to rotate, and the peeling tape peels off the graphite sheet on the base tape;

[0020] S4. The tops of the two brackets are separated again, and the translation mechanism is used to drive several lifting mechanisms to translate to the right, so that the adjacent lifting mechanisms correspond to the rubber rollers, and then steps S2 and S3 are repeated in sequence to continue the peeling of the graphite sheet;

[0027] S2a. After the second motor is turned on, the turntable is driven to rotate, and the slide follows the turntable to rotate;

[0028] S2b. The ball slides from the base slide via the transition slide to the protruding slide, during which the brake plate slides in contact with the brake groove, the movable seat does not move, and the push rod pushes the bottom end of the bracket away from the turntable during this process;

[0030] Step S3 includes the following steps:

[0031] S3a turn on the second motor mounted on the top plate, driving the drive turntable to rotate;

[0032] S3b. The contact point between the driving turntable and the driving frame moves from the proximal end to the distal end, the driving frame moves downward, and the first spring is compressed at the same time. The lifting frame is driven by the rotating plate to move downward in the descending chamber. In this process, the limit of the outer wall of the lifting frame is used to retract the limit pin into the inner cavity of the mounting block and compress the second spring. When the moving distance of the lifting frame is the spacing between two adjacent slots, the distal end of the driving turntable is separated from the outer wall of the driving frame, and the elastic force of the first spring is used to reset the rotating plate. In this process, the rotating plate rotates away from the inner cavity of the slot, and when it corresponds to the position of the adjacent slot, it is clamped into the slot by the elastic force of the torsion spring. At the same time, the limit pin is synchronously clamped into the adjacent slot by the elastic force of the second spring, and the lifting frame is limited.

[0042] S5a. During the process of the lifting frame moving to the bottom end of the stopper, the top block slides in the inner cavity of the blind groove. When the top block corresponds to the push block, the push block can be moved and the third spring can be compressed under the action of the top block. The lifting frame is pushed horizontally into the rising chamber by the push block and the third spring, so that the rotating plate and the limit pin on the other driving frame are respectively inserted into the inner cavity of the card slot;

[0043] S5b. When the lifting mechanism corresponding to the peeling tape covered with graphite sheets moves to the second motor located in the inner cavity of the base, the second motor located in the inner cavity of the base can be turned on to drive the drive turntable connected thereto to rotate, so that the lifting frame of the lifting mechanism rises;

[0044] S5c. When the lifting frame rises to the top of the ascending chamber and is located above the stopper, the lifting frame can be pushed into the descending chamber again by the push block, thereby resetting the peeling tape.

[0045] Compared with the prior art, the graphene material stripping device and the graphene stripping method of the present invention have the following beneficial effects:

[0046] (1) In view of the problems in the prior art that the manual operation efficiency is slow and the intermediate state tape is messy and it is difficult to accurately obtain one of them for observation and detection, the present invention uses the equidistant intermittent movement and lowering of the lifting frame in the lifting mechanism to enable the stripping tape to be lowered at an equal distance. At the same time, the cooperation of the rubber roller and the pressure roller can make the graphite on the base tape adhere to the surface of the stripping tape. The graphite flakes obtained by this scheme are neatly arranged, and any graphite flake can be accurately found for observation, which is convenient for finding single-layer graphene;

[0047] (2) By rotating the turntable, the slideway moves in a circle, and the two brackets can be opened and closed synchronously by using the cooperation of the sliding ball and the push rod, so as to ensure that the rubber roller and the pressure roller are stably attached to each other or away from each other. This scheme can ensure that the base tape and the peeling tape are closely attached when the graphite sheet is attached, so as to ensure stable and accurate attachment of the graphite sheet;

[0048] (3) Through the action of the translation mechanism, the moving seat can drive several lifting mechanisms to move equidistantly. When the top ends of the two brackets are opened and closed, the adjacent new peeling tape can correspond to the rubber roller, so as to continue to stick the graphite sheet. This scheme can make more new peeling tapes stick to the base tape as much as possible, ensuring that the graphite sheet stuck on the peeling tape becomes thinner and thinner, and finally a single layer of graphene is obtained;

[0049] (4) Through the action of the lifting mechanism and another driving turntable, the peeling tape covered with graphite sheets can be reset, making it easy for workers to take the peeling tape, which is convenient for operation and use in actual use;

[0050] In summary, this application can not only arrange the obtained graphite flakes neatly, but also accurately find any graphite flake for observation, making it easier to find single-layer graphene, but also automatically transfer the peeling tape that is full of graphite flakes, and align the new peeling tape with the rubber roller, so that more new peeling tapes can be attached to the base tape, so as to finally get what you want. At the same time, it is simple to operate and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0065] The following is a combination of specific implementation cases and attached Figure 1-Figure 13 The present invention is further described below, but the present invention is not limited to these embodiments.

[0066] refer to Figures 1 to 4In order to solve the problem that most of the current situations are to use manual operation to carry out the tape method to prepare single-layer graphene, which is not only inefficient, but also the graphene tapes obtained after manual operation are arranged in a messy manner, and it is impossible to accurately obtain the middle part of the graphene tape for observation and detection, a graphene material stripping device is proposed, including a base 1, a top plate 2, a lifting mechanism 3, a stripping tape 4, a bracket 5, a rubber roller 6, a base tape 7 and a pressing roller 8. The top plate 2 is installed on the top of the base 1, and the stripping tape 4 is installed on the lifting mechanism 3. The lifting mechanism 3 can make the stripping tape 4 move up and down intermittently and equidistantly. There are two brackets 5, which are rotatably installed in the inner cavity of the base 1, and the two brackets 5 are respectively arranged on both sides of the stripping tape 4, and are symmetrically arranged relative to the stripping tape 4. The upper and lower ends of the bracket 5 are both facing the stripping tape. The adhesive tape 4, the rubber roller 6 and the pressure roller 8 are rotatably installed on the top of the two brackets 5 respectively, and the base adhesive tape 7 is arranged on the outer wall of the rubber roller 6. Initially, the two brackets 5 rotate relatively on the base adhesive tape 7, so that the pressure roller 8 and the rubber roller 6 are close to the peeling adhesive tape 4. When the rubber roller 6 rotates, the peeling adhesive tape 4 moves, and the base adhesive tape 7 and the peeling adhesive tape 4 are closely attached and then peeled off from each other, and the peeling adhesive tape 4 will stick to the graphene. After repeated many times, a single layer of graphene can be obtained, wherein the base adhesive tape 7 covers an area of ​​one third to one half of the circumference of the rubber roller 6, ensuring that there is a uniform gap between the graphenes stuck by the peeling adhesive tape 4. A first motor 9 is installed on the bracket 5 connected to the rubber roller 6, and the output end of the first motor 9 passes through the bracket 5 and is connected to the rubber roller 6. Turning on the first motor 9 can drive the rubber roller 6 to rotate, wherein the first motor 9 can select HF-KP Series, MSK Series and other models are suitable for occasions requiring high precision and high response, and have excellent forward and reverse performance. The inner cavity of the base 1 is installed with a driving mechanism 10, which can drive the two brackets 5 to open and close synchronously.

[0067] Among them, the stripping tape 4 and the base tape 7 are both made of graphene tape, which is a common device on the market. It is a tape with a polyethylene terephthalate (PET) substrate. This tape has good adhesion properties and suitable mechanical strength, and can effectively peel off the graphite layer.

[0068] In this scheme, the rubber roller 6 is driven to rotate by the first motor 9, and at the same time, the lifting mechanism 3 makes the stripping tape drop at intervals and equidistantly, ensuring the close adhesion and effective stripping of the base tape 7 and the stripping tape 4, greatly improving the stripping efficiency of graphene, and facilitating the rapid preparation of single-layer graphene in laboratory research. At the same time, the design of the base tape 7 covering the circumference of the rubber roller 6 ensures that the graphene stuck on the stripping tape 4 is evenly distributed, effectively avoiding overlap and waste between graphene sheets, not only can high-quality single-layer graphene be prepared in the end, but also each graphene sheet is neatly arranged, and any graphene sheet after stripping can be accurately selected for observation and research.

[0069] The following is an introduction to the driving mechanism 10. Figures 3 to 7 The driving mechanism 10 includes a turntable 1001, a slide 1002, a limit frame 1003, a push rod 1004, a sliding ball 1005, a limit slot 1006 and a limit rod 1007. There are two turntables 1001, the two turntables 1001 are connected and coaxially arranged, and the two turntables 1001 can rotate synchronously. The inner cavity of the base 1 is installed with a third motor 21, and the output end of the third motor 21 is connected to one of the turntables 1001. When the third motor 21 is turned on, 1 can make the two turntables 1001 rotate synchronously, the slideway 1002 is installed on the side of the two turntables 1001 away from each other, the slideway 1002 includes a basic slideway 10021, a transition slideway 10022 and a protruding slideway 10023 that are interconnected, and there is a horizontal distance difference between the basic slideway 10021 and the protruding slideway 10023, the limit frame 1003 is installed in the inner cavity of the base 1, and the push rod 1004 slides through the limit frame 1003 The top of the turntable 1001 is provided with a sliding ball 1005 installed at one end of the push rod 1004, and the sliding ball 1005 is slidably embedded in the inner cavity of the slideway 1002. When the turntable 1001 rotates one circle, the sliding ball 1005 slides from the basic slideway 10021 into the transition slideway 10022, then enters the protruding slideway 10023 and returns to the basic slideway, so that the push rod 1004 moves horizontally back and forth once. The limiting groove 1006 is provided at the bottom end of the bracket 5, and the limiting rod 1007 is slidably installed at the bottom end of the bracket 5. In the limiting groove 1006, the push rod 1004 moves horizontally back and forth once, which can push the bracket 5 to rotate and reset, so that the top ends of the two brackets 5 are opened and closed once. At the same time, the cooperation of the limiting groove 1006 and the limiting rod 1007 is used to provide displacement compensation in the up and down directions to avoid interference. When the top ends of the two brackets 5 move away from each other and open, the rubber roller 6 and the pressure roller 8 move away from the stripping tape 4. Conversely, when the top ends of the two brackets 5 move close to each other and close, the rubber roller 6 and the pressure roller 8 are close to the stripping tape.

[0070] The above scheme realizes the horizontal reciprocating motion of the push rod through the coordinated work of the turntable 1001, the slide 1002 and the slide ball 1005, thereby effectively controlling the opening and closing of the bracket. The arc design of the transition slide 10022 makes the transition between the basic slide 10021 and the protruding slide 10023 smoother, so that the push rod 1004 can remain stable and smooth during the reciprocating motion, avoiding mechanical jamming. This design ensures that the stripping tape 4 can obtain stable sticking and stripping operations during the stripping process, improves the accuracy and efficiency of graphene material stripping, and at the same time, when the stripping is completed, the stripping tape can be separated from the base tape 7, thereby improving the reliability and operational stability of the equipment.

[0071] The specific working method of the driving mechanism 10 is: turn on the third motor 21 to drive the turntable 1001 to rotate, use the sliding ball 1005 to slide in the slide 1002, and make the push rod 1004 push the bracket 5 to rotate. When the sliding ball 1005 moves to the position of the protruding slide 10023, the distance between the top ends of the two brackets 5 is the smallest, and the rubber roller 6 and the pressure roller 8 are in contact with the peeling tape 4. When the sliding ball 1005 moves to the basic slide 10021, the top ends of the two brackets 5 are separated to the farthest.

[0072] The following is an introduction to the lifting mechanism 3, mainly referring to Figures 8 to 12, the lifting mechanism 3 includes a frame 301, stoppers 302, driving frames 303, lifting frames 304, card slots 305, rotating plates 306, limiting blocks 307, torsion springs 308, first springs 309, mounting blocks 3010, limiting pins 3011, second springs 3012, third springs 3013, pushing blocks 3014, blind slots 3015 and top blocks 3016. The number of stoppers 302 is two, which are symmetrically installed in the inner cavity of the frame 301. The stoppers 302 divide the inner cavity of the frame 301 into a descending chamber 3001 and an ascending chamber 3002. The number of driving frames 303 is two, which are respectively installed in the descending chamber 3001 and the ascending chamber 3002. The two driving frames 303 are axially symmetrically arranged, and the two driving frames 303 respectively extend out of the outer wall of the frame 301. The driving frame 303 is arranged in a "U" shape. The lifting frame 304 is installed inside one of the driving frames 303. The lifting frame 304 is a rectangular frame with an open middle design. The peeling tape 4 is fixedly installed on the lifting frame 304, ensuring that the upper and lower ends of the peeling tape 4 are fixed to the upper and lower side frames of the lifting frame 304. The main body of the peeling tape 4 is designed to be suspended. The number of card slots 305 is several, and several card slots 305 are equidistantly opened on the lifting frame 304. The number of rotating plates 306 is two, which are respectively installed on one side of the driving frame 303 located in the inner cavity of the frame 301, and the two rotating plates 306 are symmetrically arranged. The shape of the limiting block 307 is triangular. The limiting block 307 is installed on the driving frame 303, and the limiting block 307 contacts the rotating plate 306, ensuring that the rotating plate can only rotate and reset in one direction and is limited from rotating in the reverse direction. The two ends of the torsion spring 308 are respectively connected to the driving frame 303 and the rotating plate 306, ensuring that the rotating plate 306 has the ability to reset after rotation. The limiting block 307 is inserted into the inner cavity of the card slot 305, and the relative side of the rotating plate 306 and the limiting block 307 is arc-shaped. The two ends of the first spring 309 are respectively connected to one side of the driving frame 303 extending out of the frame 301 and the outer wall of the frame 301. Pressing the driving frame 303 can make it move into the inner cavity of the frame 301, and after removing the external force, the driving frame 303 can automatically reset. The mounting block 3010 is installed on the inner wall of the frame 301. One end of the limiting pin 3011 is slidably inserted into the inner cavity of the frame 301, and the other end of the limiting pin 3011 is inserted into the card slot 305. The two ends of the second spring 3012 are respectively connected to the inner wall of the mounting block 3010 and the limiting pin 3011. The limiting pin 3011 is inserted into the inner cavity of the card slot 305, and the relative side of the limiting pin 3011 and the driving frame 303 is arc-shaped. When the limiting pin 3011 is stressed, it moves into the inner cavity of the mounting block 3010 and compresses the second spring 3012. After removing the external force, the elastic force of the second spring 3012 can make the limiting pin 3011 reset. The distance between the limiting pin 3011 and the rotating plate 306 is an integer multiple of the distance between adjacent two card slots 305. The blind slot 3015 is opened on the inner wall of the frame 301. The top block 3016 is installed on the lifting frame 304. One end of the third spring 3013 is installed on the inner wall of the blind slot 3015,The other end of the third spring 3013 is connected to the push block 3014.

[0073] The setting of this mechanism realizes the stable up and down movement of the peeling tape. The design of the rotating plate 306 and the limit block 307 ensures that the rotating plate can only rotate and reset in one direction, ensuring the stability and accuracy of the lifting frame during movement. Through the setting of the descending chamber 3001 and the ascending chamber 3002 and the cooperation of the third spring 3013, the push block 3014, the blind groove 3015 and the top block 3016, the position lifting cycle of the lifting frame 304 can be realized, ensuring that after the peeling tape 4 is lowered and used, it can return to the initial position for easy removal.

[0074] The specific working principle of the lifting mechanism 3 is as follows: the driving frame 303 is pressed to move it downward and compress the first spring 309, and the lifting frame 304 is moved downward in the descending chamber 3001 by driving the rotating plate 306, and at the same time, the limiting of the outer wall of the lifting frame 304 is used to retract the limiting pin 3011 into the inner cavity of the mounting block 3010 and compress the second spring 3012. When the moving distance of the lifting frame 304 is the spacing between two adjacent slots 305, the external force applied to the driving frame 303 is removed to reset it under the action of the first spring 309. In this process, the rotating plate 306 rotates out of the inner cavity of the slot 305, and when it corresponds to the position of the adjacent slot 305, the rotating plate 306 is snapped in, and at the same time, the limiting pin 3011 is synchronously snapped in after corresponding to the adjacent slot 305, so that the lifting frame 304 is positioned after moving, and the lifting frame 304 can be intermittently equidistant by repeatedly pressing the driving frame 303. When the lifting frame 304 moves to the bottom position of the stopper 302 in the descending chamber 3001, the push block 3014 can be moved and the third spring 3013 can be compressed under the action of the top block 3016. When the lifting frame 304 is completely located at the bottom end of the stopper 302, the lifting frame 304 is pushed by the push block 3014 and the third spring 3013 to move horizontally into the ascending chamber 3002, so that the rotating plate 306 and the limit pin 3011 on the other driving frame 303 are respectively inserted into the inner cavity of the card slot 305. Pressing the driving frame 303 at this position can make the lifting frame 304 rise in the ascending chamber 3002. When the lifting frame 304 rises to the top of the ascending chamber 3002 and is located above the stopper 302, the push block 3014 can be used to push the lifting frame 304 into the descending chamber 3001 again, thereby resetting the stripping tape 4 for easy removal.

[0075] In order to facilitate the equally spaced pressing and driving of the driving frame 303 and ensure the uniform movement of the stripping tape 4, the following scheme is proposed: the second motor 11 is respectively installed on the bottom surface of the top plate 2 and the inner cavity of the base 1, and the output end of the second motor 11 is installed with a driving turntable 12, and the driving turntable 12 corresponds to the position of the driving frame 303, the driving turntable 12 and the second motor 11 are eccentrically arranged, and the edge distance of the driving turntable 12 and the connection with the second motor 11 includes a proximal end and a distal end, and the distance difference between the proximal and distal ends of the driving turntable 12 corresponds to the distance between two adjacent slots 305. The second motor 11 is turned on to drive the driving turntable 12 to rotate, and when the contact position of the turntable with the driving frame 303 changes from the proximal end to the distal end, the driving frame 303 will be pressed. After passing the distal end, the driving frame 303 loses the external force and can be reset.

[0076] This operation mode can ensure that the driving frame 303 is pressed equally, and the accuracy of the movement of the lifting frame 304 is ensured.

[0077] According to the scheme, further, a translation mechanism 13 is installed in the inner cavity of the base 1, and a plurality of lifting mechanisms 3 are arranged at equal intervals on the translation mechanism 13. The translation mechanism 13 can be used to make the lifting mechanism 3 move horizontally at equal intervals. In addition, a slide groove 101 is opened at the top of the base 1, and a plurality of lifting mechanisms 3 slide through the slide groove 101. The width of the slide groove 101 is adapted to the thickness of the lifting mechanism 3. The lifting mechanism 3 can slide along the inner cavity of the slide groove 101, and further adjust the translation mechanism 13. The structure 13 includes a positioning rod 1301, a moving seat 1302, a brake groove 1303, a toggle groove 1304, a brake plate 1305 and a toggle rod 1306. The positioning rod 1301 is fixedly installed in the inner cavity of the base 1, and the moving seat 1302 is slidably sleeved on the positioning rod 1301. The moving seat 1302 is located between the two rotating disks 1001. The moving seat 1302 can stably move in the horizontal direction. The top of the moving seat 1302 is connected to the frame 301, and at the same time avoids The driving frame 303 extending out of the bottom of the frame 301, the number of the brake grooves 1303 and the toggle grooves 1304 is several, and the several brake grooves 1303 and the toggle grooves 1304 are staggered and arranged at the bottom of the moving seat 1302, the several brake grooves 1303 are equidistant, and the several toggle grooves 1304 are equidistant, wherein the brake groove 1303 is arranged in an arc shape, and the brake plate 1305 is fixedly installed on one side of one of the turntables 1001 facing the moving seat 1302, The brake plate 1305 is set in an arc shape, and the brake plate 1305 is adapted to the brake groove 1303. The lever 1306 is installed on the side of one of the turntables 1001 facing the moving seat 1302, and the lever 1306 corresponds to the opening position of the brake plate 1305. The lever 1306 is inserted into the inner cavity of the lever groove 1304 to drive the moving seat 1302 to move. When the lever 1306 is disengaged, the brake plate 1305 cooperates with the brake groove 1303 to prevent the moving seat from moving the rod.

[0078] In the above scheme, the positioning rod 1301 ensures the stable movement of the moving seat 1302 in the horizontal direction. The design of the brake groove 1303 and the brake plate 1305 realizes the stable braking of the moving seat through the adaptation of the two arc-shaped grooves, and effectively prevents its accidental movement in the non-working state. The combination of the lever 1306 and the toggle groove 1304 enables the moving seat 1302 to be accurately force-bearing and horizontally moved when it needs to move, and when it does not need to move, the cooperation of the brake plate and the brake groove can quickly brake, ensuring the safety and stability of the equipment.

[0079] The specific working principle of the translation mechanism 13 is as follows: the turntable 1001 rotates, and when the lever 1306 is inserted into the inner cavity of the toggle slot 1304, the moving seat 1302 can be driven to move. When the lever 1306 is separated from the inner cavity of the toggle slot 1304, the brake plate 1305 cooperates with the brake slot 1303 to brake the moving seat 1302. The spacing between two adjacent lifting mechanisms 3 is the same as the distance that the moving seat 1302 moves each time, thereby ensuring that the lifting mechanism 3 can accurately perform equidistant displacement.

[0080] Among them, the protruding slide 10023 in the slide 1002 corresponds to the position of the lever 1306. When the sliding ball 1005 enters the basic slide 10021, the lever 1306 starts to push the pushing groove 1304, thereby moving the movable seat 1302. The lever 1306 disengages from the pushing groove 1304, and the sliding ball 1005 returns to the protruding slide 10023 again, ensuring that when the movable seat 1302 moves, the top ends of the two brackets 5 are in a separated state to avoid interference.

[0081] To ensure the stability of the lifting mechanism 3, the inner cavity of the base 1 is symmetrically provided with two beams 19, and the beams 19 are provided with a plurality of guide rollers 20 for relative rotation. The guide rollers 20 roll and fit the lifting mechanism 3 to ensure the stable movement of the lifting mechanism 3.

[0082] The graphene material stripping equipment also includes the following scheme: a vertical plate 14 is installed on the top of the base 1, and a rotating frame 15 is rotatably installed on the top of the vertical plate 14. The bottom end of the rotating frame 15 corresponds to the bracket 5, and the upper and lower ends of the rotating frame 15 are both facing the position of the rubber roller 6. A raw material roller 16 is rotatably installed on the top of the rotating frame 15. The diameter of the raw material roller 16 is the same as the diameter of the rubber roller 6, and a graphite block is fixedly placed on the outer wall, and the area for placing the graphite block is adapted to the area of ​​the base tape 7. An incomplete gear 17 is installed on the top of the bracket 5, and the incomplete gear 17 is connected to the rubber roller 6. The part of the incomplete gear 17 where the teeth are set corresponds to the position of the base tape 7. A gear 18 is rotatably installed on the top of the rotating frame 15, and the gear 18 is connected to the raw material roller 16, and the incomplete gear 17 corresponds to the gear 18.

[0083] When the top end of the bracket 5 separates outward, the bottom end of the rotating frame 15 fits against the outer wall of the bracket 5. By utilizing the limit of the bracket 5, the top end of the rotating frame 15 tends to move toward the rubber roller, ensuring that the top end of the rotating frame 15 does not move away from the rubber roller 6. At this time, the position of the incomplete gear 17 corresponds to the gear 18, and the rotation of the rubber roller 6 drives the incomplete gear 17 to rotate. When the teeth begin to mesh, the rubber roller 6 and the raw material roller 16 rotate relative to each other, and the base tape 7 fits against the graphite block, so that the graphite layer can be adhered.

[0084] This solution ensures that the base tape 7 is in precise and close contact with the graphite block by setting the gear 18 and the incomplete gear 17, and ensures that the base tape 7 can adhere to enough graphite sheets.

[0085] The present invention also provides a method for exfoliating graphene using the device, comprising the following steps:

[0086] S1. The base tape 7 is bonded to the initial graphite sheet;

[0087] S2. The top ends of the two brackets 5 are brought close to each other, so that the rubber roller 6 and the pressure roller 8 are opposite to each other, and the rubber roller 6 and the pressure roller 8 are close to the peeling tape 4;

[0088] S3. The lifting mechanism 3 and the first motor 9 are started, and the lifting mechanism 3 drives the stripping tape 4 to descend, while the rubber roller 6 drives the base tape 7 to rotate, and the stripping tape 4 strips off the graphite sheet on the base tape 7;

[0089] S4. The tops of the two brackets 5 are separated again, and the translation mechanism 13 is used to drive the plurality of lifting mechanisms 3 to translate to the right, so that the adjacent lifting mechanisms 3 correspond to the rubber roller 6, and then the steps S2 and S3 are repeated in sequence to continue the peeling of the graphite sheet;

[0090] S5. After the graphite sheet is attached, the peeling tape 4 in the lifting mechanism 3 is reset.

[0091] S1 includes the following steps:

[0092] S1a. Turn on the first motor 9 to drive the rubber roller 6 and the incomplete gear 17 to rotate;

[0093] S1b. The teeth of the incomplete gear 17 mesh with the gear 18, so that the gear 18 and the incomplete gear 17 rotate relative to each other, the raw material roller 16 and the rubber roller 6 rotate relative to each other, the base tape 7 contacts the graphite block on the raw material roller 16, and then the first motor 9 is reversely started to make the rubber roller 6 and the base tape 7 leave the raw material roller 16, and the graphite block is adhered by the base tape 7 to remove the next layer of graphite sheets;

[0094] S1c. The first motor 9 stops after the surface of the base tape 7 is completely adhered to the graphite sheet.

[0095] S2 includes the following steps:

[0096] S2a. After the second motor 11 is turned on, the drive turntable 1001 rotates, and the slide 1002 rotates with the turntable 1001;

[0097] S2b. The sliding ball 1005 moves from the base slide 10021 to the protruding slide 10023 via the transition slide 10022. During this process, the brake plate 1305 is in sliding contact with the brake groove 1303, and the movable seat 1302 does not move. At the same time, the push rod 1004 pushes the bottom end of the bracket 5 away from the turntable 1001 during this process.

[0098] S2c. As the two brackets 5 rotate, the top ends of the two brackets 5 approach each other, and the rubber roller 6 and the pressure roller 8 are closely attached to the peeling tape 4.

[0099] S3 includes the following steps:

[0100] S3a. Turn on the second motor 11 mounted on the top plate 2 to drive the drive turntable 12 to rotate;

[0101] S3b. The contact point between the driving turntable 12 and the driving frame 303 moves from the proximal end to the distal end, the driving frame 303 moves downward, and at the same time compresses the first spring 309, and the lifting frame 304 moves downward in the descending chamber 3001 by driving the rotating plate 306. In this process, the outer wall of the lifting frame 304 is limited, so that the limit pin 3011 is retracted into the inner cavity of the mounting block 3010 and the second spring 3012 is compressed. The lifting frame 304 moves a distance of two adjacent When the distance between the card slots 305 is within the range, the distal end of the driving turntable 12 is separated from the outer wall of the driving frame 303, and the elastic force of the first spring 309 is used to reset the rotating plate 306. In this process, the rotating plate 306 rotates away from the inner cavity of the card slots 305, and when it corresponds to the position of the adjacent card slots 305, it is clamped into the card slot 305 by the elastic force of the torsion spring 308. At the same time, the limiting pin 3011 is synchronously clamped into the adjacent card slots 305 by the elastic force of the second spring 3012, and the lifting frame 304 is limited;

[0102] S3c while performing step S3b, the first motor 9 drives the roller 6 to rotate, so that the base tape 7 and the peeling tape 4 are equal to the descending speed, the peeling tape 4 can be the graphite on the base tape 7 to be removed;

[0103] S3d. The drive turntable 12 is continuously rotated, and the lifting frame 304 drives the peeling tape 4 to intermittently and equidistantly descend, while cooperating with the continuous rotation of the first motor 9 to ensure that the graphite sheets after each adhesion are arranged equidistantly.

[0104] Step S4 includes the following steps:

[0105] S4a. When the initial position of the peeling tape 4 is full of graphite sheets, the first motor 9 is turned off to stop the rubber roller 6, and the second motor 11 is turned off;

[0106] S4b. Turn on the third motor 21 to drive the turntable 1001 to rotate, and the sliding ball 1005 slides from the protruding slide 10023 through the transition slide 10022 into the base slide 10021. During this process, the bottom end of the bracket 5 is pulled by the push rod 1004 and approaches the turntable 1001. The top ends of the two brackets 5 move away from each other, and the rubber roller 6 and the pressure roller 8 leave the peeling tape 4;

[0107] S4c. The brake plate 1305 leaves the brake groove 1303, and the lever 1306 is inserted into the inner cavity of the toggle groove 1304, so that the movable seat 1302 can be moved. When the lever 1306 is separated from the inner cavity of the toggle groove 1304, the brake plate 1305 re-cooperates with the brake groove 1303 to achieve braking of the movable seat 1302. At this time, the peeling tape 4 on the adjacent lifting mechanism 3 corresponds to the rubber roller 6;

[0108] S4d. Then the sliding ball 1005 passes through the transition slide 10022 again, and steps S2b and S2c are repeated;

[0109] S4e. Repeat S3 to continue peeling off the graphite sheets.

[0110] Step S5 includes the following steps:

[0111] S5a. When the lifting frame 304 moves to the bottom of the stopper 302, the top block 3016 slides in the inner cavity of the blind groove 3015. When the top block 3016 corresponds to the push block 3014, the push block 3014 can be moved and the third spring 3013 can be compressed under the action of the top block 3016. The lifting frame 304 is pushed horizontally into the rising chamber 3002 by the push of the push block 3014 and the third spring 3013, so that the rotating plate 306 and the limit pin 3011 on the other driving frame 303 are respectively inserted into the inner cavity of the card slot 305;

[0112] S5b. When the lifting mechanism 3 corresponding to the peeling tape 4 covered with graphite sheets moves to the second motor 11 located in the inner cavity of the base 1, the second motor 11 located in the inner cavity of the base 1 can be turned on to drive the drive turntable 12 connected thereto to rotate, so that the lifting frame 304 of the lifting mechanism 3 rises;

[0113] S5c. When the lifting frame 304 rises to the top of the ascending chamber 3002 and is located above the stopper 302, the lifting frame 304 can be pushed into the descending chamber 3001 again by the push block 3014, so that the peeling tape 4 is reset.

[0114] The above method can realize continuous and efficient graphite sheet peeling during mechanical movement, improve peeling efficiency, realize automatic operation of the peeling process, reduce human intervention, reduce labor intensity and human errors, and make the graphite sheets evenly arranged after each peeling, so that it is convenient to accurately select any graphite sheet for observation, and it is convenient to find single-layer graphene. At the same time, the peeling tape 4 that has been attached can be automatically reset for easy removal.

[0115] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

8. A method for exfoliating graphene using a graphene material exfoliation device according to claim 7, characterized in that: S1 includes the following steps: S1a. Turning on the first motor (9) to drive the rubber roller (6) and the incomplete gear (17) to rotate; S1b. The teeth of the incomplete gear (17) mesh with the gear (18), thereby causing the gear (18) and the incomplete gear (17) to rotate relative to each other, causing the raw material roller (16) and the rubber roller (6) to rotate relative to each other, causing the base tape (7) to contact the graphite block on the raw material roller (16), and then starting the first motor (9) in the reverse direction to cause the rubber roller (6) and the base tape (7) to leave the raw material roller (16), and causing the graphite block to be adhered to the base tape (7) to remove a layer of graphite flakes; S1c. After the surface of the base tape (7) is completely adhered to the graphite sheet, the first motor (9) stops; S2 includes the following steps: S2a. After the second motor (11) is turned on, the turntable (1001) is driven to rotate, and the slideway (1002) rotates following the turntable (1001); S2b. The sliding ball (1005) moves from the base slide (10021) to the protruding slide (10023) via the transition slide (10022). During this process, the brake plate (1305) is in sliding contact with the brake groove (1303), and the movable seat (1302) does not move. At the same time, during this process, the push rod (1004) pushes the bottom end of the bracket (5) away from the turntable (1001); S2c. As the two brackets (5) rotate, the top ends of the two brackets (5) approach each other, and the rubber roller (6) and the pressure roller (8) are closely attached to the peeling tape (4); S3 includes the following steps: S3a. Turn on the second motor (11) mounted on the top plate (2) to drive the drive turntable (12) to rotate; S3b. The contact point between the driving turntable (12) and the driving frame (303) moves from the proximal end to the distal end, the driving frame (303) moves downward, and the first spring (309) is compressed at the same time. The lifting frame (304) is driven by the rotating plate (306) to move downward in the descending chamber (3001). During this process, the outer wall of the lifting frame (304) is limited, so that the limit pin (3011) is retracted into the inner cavity of the mounting block (3010) and the second spring (3012) is compressed. The lifting frame (304) moves a distance equal to the distance between two adjacent slots. When the distance between the drive plate (305) and the drive frame (303) is less than the distance between the drive plate (305), the distal end of the drive plate (12) is separated from the outer wall of the drive frame (303), and the elastic force of the first spring (309) is used to reset the rotating plate (306). During this process, the rotating plate (306) rotates to leave the inner cavity of the slot (305), and when it corresponds to the position of the adjacent slot (305), it is clamped into the slot (305) by the elastic force of the torsion spring (308). At the same time, the limiting pin (3011) is synchronously clamped into the adjacent slot (305) by the elastic force of the second spring (3012), and the lifting frame (304) is limited. S3c. While performing step S3b, the first motor (9) drives the rubber roller (6) to rotate so that the speed of the base tape (7) is equal to the descending speed of the stripping tape (4), and the stripping tape (4) can remove the graphite on the base tape (7); S3d. The driving turntable (12) is continuously rotated, and the lifting frame (304) drives the peeling tape (4) to intermittently and equidistantly descend, while cooperating with the continuous rotation of the first motor (9) to ensure that the graphite sheets after each adhesion are arranged equidistantly.

9. A method for exfoliating graphene using a graphene material exfoliation device according to claim 8, characterized in that: Step S4 includes the following steps: S4a. When the peeling tape (4) at the initial position is fully adhered to the graphite sheet, the first motor (9) is turned off to stop the rubber roller (6), and the second motor (11) is turned off at the same time; S4b. Turning on the third motor (21) drives the turntable (1001) to rotate, and the sliding ball (1005) slides from the protruding slideway (10023) through the transition slideway (10022) and then into the base slideway (10021). During this process, the bottom end of the bracket (5) is pulled by the push rod (1004) and approaches the turntable (1001), and the top ends of the two brackets (5) move away from each other, and at the same time, the rubber roller (6) and the pressure roller (8) leave the peeling tape (4); S4c. The brake plate (1305) leaves the brake groove (1303), and the lever (1306) is inserted into the inner cavity of the toggle groove (1304), so that the movable seat (1302) can be toggled to move. When the lever (1306) is separated from the inner cavity of the toggle groove (1304), the brake plate (1305) re-matches with the brake groove (1303) to achieve braking of the movable seat (1302). At this time, the peeling tape (4) on the adjacent lifting mechanism (3) corresponds to the rubber roller (6); S4d. The sliding ball (1005) then passes through the transition slide (10022) again, and steps S2b and S2c are repeated; S4e. Repeat S3 to continue peeling the graphite sheet; Step S5 includes the following steps: S5a. When the lifting frame (304) moves to the bottom end of the stopper (302), the top block (3016) slides in the inner cavity of the blind groove (3015). When the top block (3016) corresponds to the push block (3014), the push block (3014) can be moved and the third spring (3013) can be compressed under the action of the top block (3016). The lifting frame (304) is pushed horizontally into the ascending chamber (3002) by the push block (3014) and the third spring (3013), so that the rotating plate (306) and the limit pin (3011) on the other driving frame (303) are respectively inserted into the inner cavity of the slot (305); S5b. When the lifting mechanism (3) corresponding to the peeling tape (4) covered with graphite sheets moves to the position opposite to the second motor (11) located in the inner cavity of the base (1), the second motor (11) located in the inner cavity of the base (1) can be turned on to drive the driving turntable (12) connected thereto to rotate, so that the lifting frame (304) of the lifting mechanism (3) rises; S5c. When the lifting frame (304) rises to the top of the ascending chamber (3002) and is located above the stopper (302), the lifting frame (304) can be pushed into the descending chamber (3001) again by using the push block (3014), thereby resetting the peeling tape (4).
