Description

Technical Field

[0002] Carbon nanotubes are one-dimensional quantum materials composed of carbon atoms arranged in a hexagonal lattice. Due to their high mechanical strength, electrical conductivity and thermal conductivity, they have broad application prospects in many fields, such as the manufacture of transistors, sensors and other devices. With the growth of demand, chemical vapor deposition has become a common method for mass production because it can better control the growth conditions.

[0003] Depending on the growth conditions, carbon nanotubes can be divided into oriented and non-oriented arrangements. The non-oriented arrangement has a high specific surface area due to its intricate carbon network arrangement, and is suitable for the biomedical field, such as as a drug carrier to improve the sustained-release performance of drugs. Therefore, the more complex the carbon nanotube network, the more it can improve the sustained-release performance of drugs.

[0004] In the prior art, in order to prepare a more complex carbon nanotube network, a complex substrate is usually designed to provide more growth points to form a complex carbon nanotube network. However, this method is essentially a static control method, which can only control the arrangement of the bottom base points, but cannot control the direction of the carbon nanotube formation during its growth process. It is difficult to dynamically adjust the growth direction of the carbon nanotube. Once the carbon nanotube starts to grow, its direction may no longer completely follow the design of the substrate.

[0018] 3. Through the self-adjusting base mechanism configured on the disc partition, during the process of the first air duct adjustment module and the second air duct adjustment module performing air duct adjustment, it can also use the servo dial module to dial the second leak hole disc base to align it with the leak hole of the first leak hole disc base on the upper side, thereby increasing the diversion performance of the base end, so that the carbon-containing source gas can more easily contact the substrate surface at different blowing-in angles and different blowing-out angles, thereby improving the catalyst utilization rate and the growth efficiency of carbon nanotubes, and making the carbon nanotubes more stable.

[0019] 4. Through the first servo motor configured outside the self-adjusting substrate mechanism, under the servo drive of the first servo motor, the substrate end can also rotate 360 ​​degrees, so that the carbon source gas duct and the deposited catalyst substrate can rotate. On the one hand, it can ensure that the carbon source gas is more evenly distributed in the reaction chamber, reduce the situation of local concentration being too high or too low, thereby improving the uniformity of carbon nanotube growth. On the other hand, multi-angle catalyst deposition is achieved, thereby forming a more uniform catalyst layer at different positions of the substrate, which further helps to form a complex carbon nanotube network.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 9 The present invention further describes a carbon nanotube production device and a method for using the same.

[0025] A carbon nanotube production device, comprising a support base 1, a gantry 2, and a servo gas supply module 4, wherein the gantry 2 is fixedly mounted on the upper surface of the support base 1, a carbon nanotube preparation mechanism 3 is disposed at the inner upper end of the gantry 2, a catalyst coating mechanism 5 with an output end facing the carbon nanotube preparation mechanism 3 is disposed at the top of the gantry 2, and the servo gas supply module 4 is fixedly mounted on the bottom of the gantry 2 for providing carbon source gas to the carbon nanotube preparation mechanism 3; The carbon nanotube preparation mechanism 3 includes an expansion frame 31 fixedly connected to the inner side of the gantry 2, and a first air duct adjustment module 32, an external expansion cover mechanism 33 and a second air duct adjustment module 332 arranged on the side of the expansion frame 31; The first air duct adjustment module 32 includes a disc partition 322 and a gear ring 325 movably mounted on the outer surface of the disc partition 322, the outward expansion cover mechanism 33 includes a first electric telescopic rod 327 and a sealed external cover tube 331 arranged at both ends of the gear ring 325, and the second air duct adjustment module 332 includes an arc-shaped cover frame 3321 on the outer circular edge of the sealed external cover tube 331, and the inner side of the arc-shaped cover frame 3321 is movably provided with a first air guide interface 3327; By rotating the gear ring 325 and changing the sealed external cover tube 331 connected to the outside by the first electric telescopic rod 327, the position of the carbon source gas blowing end can be changed. In combination with the movable first air guide interface 3327, the position of the carbon source gas blowing end can be changed to achieve dynamic adjustment of the growth direction of carbon nanotubes.

[0026] In view of the problem that the prior art cannot control the direction of carbon nanotube formation during its growth process and it is difficult to dynamically adjust the growth direction of carbon nanotubes, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution mainly consists of a support base 1, a gantry 2, a carbon nanotube preparation mechanism 3, a servo gas supply module 4 and a catalyst coating mechanism 5. The support base 1 and the gantry 2 serve as the overall lifting structure of the device, and their supporting function, and corresponding universal wheels can be configured at the bottom of the support base 1 according to needs to improve the overall mobility, and the servo gas supply module 4 is a gas mixing device used in the prior art to provide carbon source gas. In the working process, an inert carrier gas, such as argon and nitrogen, can be used to carry the carbon source gas into The reaction chamber is used to uniformly transport the carbon source gas to the reaction zone and provide a stable gas flow rate, while the carbon nanotube preparation mechanism 3 is composed of a first air duct adjustment module 32 and a second air duct adjustment module 332 at both ends controlled by an external expansion cover mechanism 33. The second air duct adjustment module 332 can be pushed outward by the external expansion cover mechanism 33 to expose the internal catalyst substrate end, and cooperate with the catalyst coating mechanism 5 to perform multi-layer catalyst coating, and then introduce a mixed gas containing carbon source gas through the two air duct modules to dynamically adjust the gas flow direction to control the growth direction, thereby solving the problem that the prior art cannot control the direction of carbon nanotube formation during its growth process and is difficult to dynamically adjust the growth direction of carbon nanotubes.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the first air duct adjustment module 32 also includes a first servo motor 321 fixedly connected to the surface of the expansion frame 31, the disc partition 322 is fixedly installed on the surface of the first servo motor 321, and the output end of the first servo motor 321 passes through the axis of the disc partition 322; and a self-adjusting base mechanism 34 is fixedly installed on the output end that passes through; with the side configured with the self-adjusting base mechanism 34 as the front side of the disc partition 322, a gear ring 325 is movably installed at the outer edge position of the rear side of the disc partition 322, and the rear side of the disc partition 322 is located at the position of the inner circle of the gear ring 325. A second servo motor 323 is fixedly installed through a bracket at the position of the inner circle of the gear ring 325, and a gear sleeve head 324 is fixedly installed at the output end of the second servo motor 323, and the side teeth of the gear sleeve head 324 are meshed with the inner ring teeth of the gear sleeve 325 to drive the gear sleeve 325 to perform 360-degree servo rotation.

[0028] Among them, the configured first servo motor 321 is fixedly installed as a whole at the surface axial position of the disc partition 322, and its output end penetrates into the other side of the disc partition 322, and a corresponding sealing structure is provided at its penetration end position to ensure that the self-adjusting base mechanism 34 at the axial position on the other side is driven to rotate.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, two groups of L-shaped extending side plates 326 extending toward the rear side of the disc partition 322 are fixedly installed on the surface of the gear ring 325 at an interval of 180; and each side of the L-shaped extending side plate 326 is fixedly installed with a flush corresponding first electric telescopic rod 327, and the output end of the first electric telescopic rod 327 faces the front side of the disc partition 322; and a sealed external cover cylinder 331 is fixedly installed on its output end, and the circular mouth diameter of the sealed external cover cylinder 331 is the same as the diameter of the disc partition 322; and a sealing sleeve 328 is fixedly installed at the position where the front side edge of the disc partition 322 and the contact end of the sealed external cover cylinder 331 are located.

[0030] Among them, the configured first electric telescopic rod 327 is a device used for servo telescopic in the prior art, which controls the sealed external cover tube 331 at its output end to move forward and backward to expand or retract, and after retraction, it forms a preparation bin with the fitted disc partition 322.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the arc-shaped sleeve frame 3321 is fixedly connected to the circular edge of the sealed external cover tube 331, and winding sleeves 3322 are fixedly installed at the two side ends of the arc-shaped sleeve frame 3321; and a sealing cloth strip 3323 that can be pulled out is wound in each side winding sleeve 3322; and an arc clamping block 3325 is fixedly connected to the pulled-out end of the two sealing cloth strips 3323, and the surface of the arc clamping block 3325 is fixedly installed with a corresponding first air guide interface 3327, and the second edge sealing notch sleeves 3326 are fixedly installed on both sides of the arc clamping block 3325, and the first edge sealing notch sleeves 3324 are fixedly installed on both sides of the sealing cloth strip 3323, and arc-shaped track notches for the first edge sealing notch sleeve 3324 and the second edge sealing notch sleeve 3326 to be sealed and fitted are opened on the two side edges inside the frame of the arc-shaped sleeve frame 3321.

[0032] Among them, the configured arc-shaped sleeve frame 3321 is an integral structure with the sealed external cover cylinder 331, which is located on the outer circular ring edge of the sealed external cover cylinder 331, and is an arc-shaped opening frame structure as a whole. Corresponding arc-shaped track grooves are opened on both sides of the inner wall of the opening frame to engage the first edge sealing groove sleeve 3324 and the second edge sealing groove sleeve 3326, so that when the arc block 3325 moves, its sealing cloth strip 3323 can stably follow the movement, and the corresponding sealing cloth strip 3323 is an airtight sealing cloth strip with certain toughness in the prior art, which is used to seal one end of the opening frame of the arc-shaped sleeve frame 3321, and the winding sleeves 3322 at the symmetrical positions on both sides are winding devices that can be reset and rotated in the prior art, similar to the automatic retracting tape measure in the prior art, so as to convey the sealing cloth strip 3323 that can be retracted in real time.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, the sealed external cover cylinder 331 is a cylindrical structure as a whole; and the side facing the disc partition 322 is in an open state, an electric louver air outlet hood 334 is fixedly installed at the bottom of the circular edge of the sealed external cover cylinder 331, and the bottom of the electric louver air outlet hood 334 is fixedly connected with a second air guide interface 333 for communicating with the output end of the servo air supply module 4, and a third servo motor 3329 is fixedly installed at the outer center position of the sealed external cover cylinder 331, and an L-shaped rotating plate 33210 is fixedly installed on the output end of the third servo motor 3329, and a cylindrical sleeve 3328 is fixedly installed on the side of the first air guide interface 3327, and the end of the L-shaped rotating plate 33210 away from the third servo motor 3329 is movably inserted into the cylindrical sleeve 3328.

[0034] The electric shutter air outlet cover 334 is a shutter cover structure capable of controlling the air outlet to swing left and right in the prior art, and is controlled by a built-in electric motor to control the left and right blowing angle of the wind blown in by the second air guide interface 333; The specific adjustment process of the configured first air duct adjustment module 32 and the second air duct adjustment module 332 is as follows: First, the first electric telescopic rod 327 on the L-shaped extended side plate 326 is extended outward, and the sealed external cover tube 331 on the outside is expanded outward to expose the self-adjusting base mechanism 34 on the inner side of the disc partition 322, and the catalyst is applied on its surface by the catalyst coating mechanism 5. After the coating is completed and the deposition is carried out, the sealed external cover tube 331 is closed again; Then, through the output end of the servo air supply module 4, the carbon source gas is injected into the inside of the sealed external cover tube 331 on the side of the second air guide interface 333 in coordination with the conduit. The carbon source gas is combined with the catalyst and grows under the set temperature and gas conditions to become carbon nanotubes. The growth of the carbon nanotubes can be observed by rotating the gear sleeve 324 at the output end of the second servo motor 323 to drive the outer meshing gear ring 325 to rotate. The sealed external cover tube 331 is connected to the gear ring 325 through the first electric telescopic rod 327. Therefore, during the rotation of the gear ring 325, the sealed external cover tube 331 will also rotate. The end for injecting gas, that is, the second air guide interface 333, is fixedly installed on the sealed external cover tube 331. Therefore, during the rotation of the sealed external cover tube 331, the end for injecting gas will also rotate, so that the carbon source gas can be blown to one end of the base from different directions, so that the growth base points of the carbon nanotubes can be arranged in a staggered manner. Then, in order to prepare carbon nanotubes with more complex growth shapes, the L-shaped rotating plate 33210 at the output end of the third servo motor 3329 can be rotated, such as controlling the L-shaped rotating plate 33210 to rotate clockwise. Since the L-shaped rotating plate 33210 and the first air guide interface 3327 are movably fitted through the cylindrical sleeve 3328, the circular arc block 3325 in the circular arc sleeve 3321 can be synchronously driven to rotate clockwise along the inner side during the clockwise rotation of the L-shaped rotating plate 33210, so that the first air guide interface 3327, that is, the air outlet side is offset clockwise, which is different from the direct blowing from bottom to top, and the air duct of the carbon source gas can be synchronously offset. By reciprocating and offsetting the air outlet, carbon nanotubes with different directions and arrangements can be blown out, so that the carbon network arrangement is more intricately arranged, so as to prepare a carbon nanotube carrier with better sustained release performance; Finally, after the deposited multi-layer catalyst reacts completely with the carbon source gas to prepare the corresponding carbon nanotube carrier, annealing heat treatment is performed to optimize the structure of the carbon nanotube, and the sealed external cover tube 331 is unfolded outward again by the first electric telescopic rod 327 to expose the internal structure, which is convenient for taking the carbon nanotubes and daily maintenance. In addition, since the electric louver air outlet hood 334 is arranged at the air inlet position of the second air guide interface 333, the air outlet direction can also be adjusted left and right during the process of blowing in the carbon source gas, which is similar to the blowing method of the air conditioner in the prior art, so that the air duct formed by the carbon source gas can be further controlled. In order to detect the growth situation in real time, a corresponding visible transparent component can be set at the outer end of the sealed external cover tube 331 to facilitate operation and control.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the self-adjusting base mechanism 34 includes a platform partition 341, and the platform partition 341 extends equidistantly to both sides with the output end of the first servo motor 321 as the axis; and the overall length of the side is the same as the diameter of the circular mouth of the sealed external cover tube 331, and a first leak hole disk base 342 is fixedly installed at the middle position of the upper surface of the platform partition 341, and a second leak hole disk base 344 that is in contact and coaxial is movably installed at the bottom of the first leak hole disk base 342.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a tooth opening is provided on the outer edge of the second leakage hole disk base 344, and a servo toggle module 343 corresponding to the side tooth opening of the second leakage hole disk base 344 is fixedly installed on the lower surface of the platform partition 341 through a bracket, and hot air supply modules 345 with the output end facing the first leakage hole disk base 342 are fixedly installed at both side ends of the upper surface of the platform partition 341, and a temperature monitoring module 35 is fixedly installed on the outer surface of the sealed external cover tube 331.

[0037] Among them, the configured temperature monitoring module 35 is a temperature monitoring device in the prior art, which is installed on the outer surface of the sealed external cover tube 331, and uses its sensor end extending into the interior to monitor the internal temperature in real time, so as to better control the growth environment. The hot air supply module 345 is also a device used for heating in the prior art, including the use of microwave heating technology, which directly heats the gas and substrate in the reaction chamber through microwave radiation, or uses a resistive heating element, such as a heating wire, which surrounds the reaction chamber and increases the temperature inside the reaction chamber through electric current heating, etc. On the one hand, it is used to heat the applied catalyst to make it deposited, and on the other hand, it is used to heat the reaction chamber to catalyze it into carbon nanotubes.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the catalyst coating mechanism 5 includes a linear motor 51 fixedly installed at both sides of the upper end of the inner wall of the gantry 2, an automatic pumping module 52 is fixedly installed on the output end of the linear motor 51, and two groups of communicating and corresponding storage tanks 53 are fixedly installed on the extraction end of the automatic pumping module 52.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a multi-axis manipulator 54 is fixedly installed at the bottom of the automatic pump module 52, a spray head 55 is fixedly installed on the output end of the multi-axis manipulator 54, and an infusion hose is connected between the spray head 55 and the output end of the automatic pump module 52.

[0040] Among them, the linear motor 51 and the automatic pump module 52 are conventional configurations in the prior art. The pump end is controlled to be linearly driven up and down to fit the spray head 55 on the substrate, and the multi-axis manipulator 54 is also a device for multi-axis movement in the prior art to control the spray head 55 to move to any position of the substrate. The two sets of storage tanks 53 are set and combined with the automatic pump module 52 to configure a catalyst solution with higher stability in real time. Taking the formation of carbon nanotubes by catalytic gas containing carbon source through chemical vapor deposition as an example, the catalyst can be deposited by the sol-gel method. The reagent is deposited on the substrate. At this time, the material of the first leak disk substrate 342 as the substrate can be a transition metal salt, such as ferric chloride, ferric sulfate, nickel chloride, nickel nitrate, cobalt chloride, etc. These salts can be used to provide catalyst metal ions, and the two groups of storage tanks 53 at the reagent end can be configured with alcohol solvents, such as ethanol, isopropanol, etc. These solvents can dissolve metal salts or organic metal compounds and help form sol. The sol is coated on the substrate and dried at a certain temperature with the hot air supply module 345 to remove the solvent, solidify the coating, and activate the catalyst. The adjustment process of the self-adjusting base mechanism 34 is as follows: First, through the servo drive action of the output end of the first servo motor 321, the platform partition 341 at its output end is controlled to be in a horizontal state to facilitate the catalyst coating of the catalyst coating mechanism 5. During the coating, the automatic pump module 52 is controlled by the linear motor 51 to move downward to cooperate with the multi-axis manipulator 54 to move the spray head 55 to the surface of the first leak hole disk base 342, and multiple layers of reagents are coated on the non-leakage area of ​​the first leak hole disk base 342; Then, the sealed external cover tube 331 is retracted by the first electric telescopic rod 327, and the applied reagent is solidified and the catalyst is activated under the action of the hot air supply modules 345 on both sides of the platform partition 341; Finally, the motor in the servo toggle module 343 and the gear at its output end are used to drive the second leakage hole disc base 344 meshing on the outside to rotate, so that the leakage holes of the second leakage hole disc base 344 are aligned with the leakage holes of the first leakage hole disc base 342 to facilitate air guidance.

[0041] The method for preparing carbon nanotubes comprises the following steps: S1: First, the outer sealed external cover tube 331 is unfolded by the external unfolding cover mechanism 33 to expose the self-adjusting base mechanism 34 to be coated with the reagent, and the second leak hole disc base 344 is rotated by the servo toggle module 343 to block the leak hole of the first leak hole disc base 342; S2: Then, the linear motor 51 controls the multi-axis manipulator 54 to squeeze the reagent in the storage tank 53 and apply it to the non-leak hole area of ​​the first leak hole disc base 342, and then the external cover tube 331 is tightly sealed by the external cover mechanism 33; S3: Then, the surface of the first leak hole disk substrate 342 is heated by the hot air supply module 345, and the servo air supply module 4 is used to pass the gas containing the carbon source into the sealed external cover tube 331 to prepare carbon nanotubes; S4: Finally, during the preparation of carbon nanotubes, the position of the carbon source gas blowing end can be changed by the first air duct adjustment module 32, and the position of the carbon source gas blowing end can be changed in cooperation with the second air duct adjustment module 332 to dynamically adjust the growth of carbon nanotubes.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
