Description

Technical Field

[0001] The present invention relates to the technical field of thermal conductive gel preparation, and in particular to a thermal conductive gel with ultra-high thermal conductivity, a preparation device and a preparation method thereof. Background Art

[0002] Thermally conductive gel with ultra-high thermal conductivity effectively reduces the temperature of electronic components and ensures stable operation of the equipment. For example, in scenarios with extremely high heat dissipation requirements, such as the signal transmission module of 5G base stations and the battery management system of new energy vehicles, it can effectively avoid problems such as signal instability and battery performance degradation caused by overheating. The preparation device is a device specially designed for the production of ultra-high thermal conductivity thermal conductive gel. Taking the common stirring preparation device as an example, it is equipped with a specially designed stirring component, such as multiple sets of stirring blades with different angles and different speeds. The preparation method is a series of process steps followed in the production of ultra-high thermal conductivity thermal conductive gel. First, the raw materials are pretreated, such as surface modification of high thermal conductivity fillers, and treatment with special chemical reagents to make their surface have better affinity with the silicone matrix, so that they can be more evenly dispersed during subsequent stirring and mixing. However, some existing devices and methods for preparing ultra-high thermal conductivity gels typically utilize rigidly connected inner wall cleaning components, and the stirring blades only achieve radial mixing. This fails to account for the varying curvatures of the inner walls of mixing barrels of varying specifications, resulting in loose contact between the scraper and the barrel wall, causing residual material waste and inadequate localized stirring, impacting gel uniformity. Furthermore, these methods fail to account for the lack of upward stirring of material deposited at the bottom of the barrel, leading to low overall stirring efficiency and difficulty meeting the stringent requirements for preparing high thermal conductivity gels.

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 efforts are within the scope of protection of the present invention.

[0011] Reference Figures 1 to 3 , the reference provided by the present invention Figures 1 to 4, an embodiment provided by the present invention: a device for preparing ultra-high thermal conductive thermal gel, comprising an operating box 1, the operating box 1 serving as the main supporting structure of the device, providing a sliding track for a load-bearing plate 30 internally, and integrating control components externally for operation by staff to realize the lifting and lowering of the load-bearing plate 30 and the start and stop of motor 1 4 and motor 2 13, which is the control and bearing core of the entire device, the right end bottom of the operating box 1 is fixedly connected to a limit cover 2, the limit cover 2 is fixed to the right end bottom of the operating box 1, and a closed space is formed inside to install components such as a fixed box 3 and a fixed plate 10, and the bottom end cooperates with the top of the mixing barrel to limit the position, ensuring that the mixing barrel is accurately aligned with the stirring component inside the device when it is lifted and lowered, thereby avoiding position deviation between the stirring component and the barrel wall, and the interior of the limit cover 2 is fixedly connected with a fixing box 3 , the fixed box 3 is installed inside the limit cover 2, and a groove is provided on the inner wall to mesh with the output gear 2 8, providing installation support for the drive component, limiting the movement trajectory of the output gear 2 8, ensuring its stable meshing with the output gear 1 6, and ensuring the accuracy and stability of power transmission when the stirring blade 9 rotates. The top of the fixed box 3 is fixedly connected to the drive component, and the drive component includes a motor 1 4. The motor 1 4 serves as the power source of the drive component. It drives the rotating rod 5 to rotate through the driving end, providing rotational power for the rotating rod 5, the output gear 1 6, the rotating column 7 and the stirring blade 9. The speed can be adjusted to meet the requirements of the stirring speed in the preparation process of different thermal conductive gels. The driving end of the motor 1 4 is fixedly connected to the rotating rod 5. One end of the rotating rod 5 is connected to the driving end of the motor 1 4, and the other end is fixed to the bottom At the top of the plate 20, an output gear 6 is fixed on the outside of the middle part, and a sliding channel is provided inside for the sliding rod 21 to slide up and down, which has the dual functions of transmitting the power of the motor 4 and guiding the axial movement of the sliding rod 21. The outside of the rotating rod 5 is fixedly connected with an output gear 6, which is fixed to the outside of the rotating rod 5 and meshes with the two output gears 28, and transmits the rotational power of the rotating rod 5 to the rotating columns 7 on both sides synchronously. The power distribution is achieved through gear transmission, so that the stirring blades 9 on both sides rotate synchronously, expanding the stirring range. The inside of the motor 4 is slidably connected to two rotating columns 7, which run through the inside of the motor 4 and are rotatably connected to the fixed box 3 at both ends. The output gear 28 and the stirring blade 9 are fixed on the outside, and the gear transmission is transmitted through the meshing of the output gear 28 and the output gear 6. The rotating power of the motor is converted into its own rotation, driving the stirring blade 9 to stir the material in the central area of the stirring barrel. The outside of the rotating column 7 is fixedly connected with the output gear 2 8, which is engaged with the output gear 1 6 and fixed to the top of the rotating column 7. It is limited by the groove on the inner wall of the fixed box 3 to ensure that there is no axial movement during the gear transmission process, and the power is stably transmitted to the rotating column 7 to ensure the smooth rotation of the stirring blade 9. The two output gears 2 8 are engaged with the output gear 1 6. The outside of the rotating column 7 is fixedly connected with multiple stirring blades 9. Multiple stirring blades 9 are evenly distributed on the outside of the rotating column 7. When the rotating column 7 rotates at high speed, shear force is generated on the material in the stirring barrel, breaking the material and promoting mixing. It is the core component for achieving preliminary stirring of materials in the preparation process of thermal conductive gel.The interior of the rotating rod 5 is slidably connected to the exterior of the sliding rod 21. The interior of the limit cover 2 is fixedly connected to a fixing plate 10. The fixing plate 10 is fixed inside the limit cover 2. The top end supports the transmission assembly, and the bottom end is connected to the inner wall of the limit cover 2, forming a protective structure for the transmission components such as the worm 14 and the turbine 12 to prevent external impurities from entering and affecting the transmission accuracy. At the same time, it provides a mounting base for the motor 2 13. Reference Figures 2 to 4The top of the fixed plate 10 is fixedly connected with a transmission assembly, which includes a rotating ring 11. The rotating ring 11 is sleeved on the outside of the rotating rod 5, and a turbine 12 is fixed on the top. A bevel gear 16 and a limit box 15 are set on the outside. The power of the motor 2 13 is converted into its own circumferential rotation through the engagement of the turbine 12 and the worm 14, driving the bevel gear 16, the limit box 15 and the rotating plate 23 to rotate synchronously. The top of the rotating ring 11 is fixedly connected with a turbine 12. The turbine 12 is fixed to the top of the rotating ring 11 and engages with the worm 14, converting the axial rotation of the worm 14 into the circumferential rotation of the rotating ring 11. The speed is reduced and the torque is increased through gear transmission, so that the rotating ring 11 rotates at a speed suitable for the scraper 27 to fit the barrel wall and the rotating blade 19 to stir the material. The top of the fixed plate 10 is fixedly connected with a motor 2 13, which is fixed to the top of the fixed plate 10. The driving end is connected to the worm 14, which provides independent power for the transmission component. Its speed is synchronized with the motor 1 4. Through the engagement of the worm 14 and the turbine 12, the rotating ring 11, the bevel gear 16 and other components are driven to rotate, thereby realizing the linkage operation of cleaning the inner wall of the mixing barrel and mixing the materials up and down. The driving end of the motor 2 13 is fixedly connected with the worm 14, which is connected to the driving end of the motor 2 13. The external helical teeth are engaged with the turbine 12, converting the high-speed rotation of the motor 2 13 into the low-speed and high-torque rotation of the turbine 12. The self-locking characteristics of the worm 14 transmission are used to prevent the rotating ring 11 from rotating inversely due to load inertia after shutdown, thereby ensuring the safety of the device. The outside of 14 is meshed with the outside of the turbine 12, and the external rotation connection of the rotating ring 11 is connected with multiple limit boxes 15. Multiple limit boxes 15 are evenly distributed on the outside of the rotating ring 11, and the interior contains connecting rods 17, bevel gears 18 and other components to limit the rotation trajectory of the connecting rod 17 to avoid interference between the rotating blades 19 and the inner wall of the mixing barrel or other components, thereby ensuring the stability of the rotating blades 19 when rotating. The external part of the rotating ring 11 is fixedly connected with multiple bevel gears 16. The bevel gear 16 is fixed on the outside of the rotating ring 11 and meshes with the bevel gear 2 18 to convert the circumferential rotation power of the rotating ring 11 into the axial rotation power of the connecting rod 17. By changing the direction of power transmission, the rotating blades 19 are driven to rotate horizontally at the bottom of the mixing barrel, thereby realizing the material from Stirring from bottom to top, the internal rotation of the limit box 15 is connected to multiple connecting rods 17, and the two ends of the connecting rod 17 are rotatably connected to the limit box 15. The middle part is fixed with a bevel gear 2 18 and a rotating blade 19, which receives the power of the rotating ring 11 through the bevel gear transmission, and drives the rotating blade 19 to rotate at high speed. Its length and angle design ensure that the rotating blade 19 is close to the bottom of the mixing barrel, and the sedimentation material is lifted upward to improve the mixing uniformity. The outside of the connecting rod 17 is fixedly connected with a bevel gear 2 18, which is engaged with the bevel gear 1 16 and fixed to the top of the connecting rod 17. The horizontal rotation power of the rotating ring 11 is converted into the vertical rotation power of the connecting rod 17 through gear transmission, so that the rotation direction of the rotating blade 19 forms convection with the stirring blade 9, thereby enhancing the material mixing effect.The outside of the connecting rod 17 is fixedly connected to a rotating blade 19. The rotating blade 19 is fixed to the outside of the connecting rod 17 and is distributed in a spiral shape. When the connecting rod 17 rotates, it generates an upward thrust on the material at the bottom of the mixing barrel, forming a bottom-up material flow. Combined with the radial stirring of the stirring blade 9, it eliminates the stirring dead angle and improves the stirring efficiency during the preparation of the thermal conductive gel. Among them, the two bevel gears 18 are meshed with one of the bevel gears 16. The internal sliding connection of the drive assembly is a sliding rod 21; Reference Figure 5 and Figure 7The outside of the sliding rod 21 is fixedly connected to two limit plates 22. The sliding rod 21 passes through the inside of the rotating rod 5, and the bottom end extends to the bottom end of the inner wall of the mixing barrel. The external fixed limit plate 22 and the fixed block 24 can slide axially along the rotating rod 5, and contact the bottom of the barrel through the bottom end to sense the position of the mixing barrel and transmit the displacement signal, triggering the action of the limit plate 22, the rotating plate 23 and other components to achieve automatic fitting and resetting of the scraper 27. The limit plate 22 is fixed to the outside of the sliding rod 21, and the edge is embedded in the groove of the rotating rod 5 and the inner wall of the rotating ring 11. When the sliding rod 21 slides up and down, it rolls in the groove to limit the radial displacement of the sliding rod 21, ensuring that it only moves in the axial direction, and at the same time converting the linear motion of the sliding rod 21 into the rotational motion of the rotating plate 23. There are two rotating plates 23 connected to the internal rotation. The two ends of the rotating plate 23 are rotatably connected to the limit plate 22 and the connecting box 26 respectively. The middle part is connected to the sliding rod 21 through a bearing. When the limit plate 22 slides with the sliding rod 21, it rotates due to the restriction of the groove track, driving the connecting box 26 to make a circular motion along the edge of the bottom plate 20, so that the scraper 27 always fits the inner wall of the mixing barrel. The outside of the sliding rod 21 is fixedly connected with two fixed blocks 24. The fixed block 24 is fixed in the middle of the sliding rod 21 and is used to block the spring 1 25. When the sliding rod 21 slides downward, the spring 1 25 is compressed to store energy. After the mixing is completed, the spring 1 25 resets to provide a reverse thrust to ensure that the sliding rod 21 accurately returns to its initial position to avoid position deviation due to gravity or vibration. Two springs 25 are provided, which are sleeved on the outside of the sliding rod 21, and the two ends respectively abut against the fixed block 24 and the inner wall of the rotating rod 5. When the mixing barrel rises and pushes the sliding rod 21 to slide up, the stored energy is compressed. After the mixing is completed, the elastic force is released to push the sliding rod 21 to quickly reset, ensuring that the scraper 27 is separated from the barrel wall in time, which is convenient for disassembly of the mixing barrel. The far ends of the multiple rotating plates 23 are respectively fixedly connected with the connecting boxes 26. The connecting boxes 26 are rotatably connected to the end of the rotating plate 23, and the bottom is slidably connected to the bottom plate 20. The scraper 27, the telescopic rod 28 and other components are accommodated inside. When the rotating plate 23 rotates, it makes a circular motion along the edge of the bottom plate 20, driving the scraper 27 to rotate against the barrel wall to remove the material adhering to the barrel wall. The near ends of the two connecting boxes 26 are slidably connected There is a bottom plate 20, which is fixed to the bottom end of the rotating rod 5, and the diameter matches the inner diameter of the mixing barrel. When the rotating rod 5 rotates, the edge contacts the bottom of the mixing barrel, scraping the deposited material at the bottom of the barrel to prevent the material from accumulating at the bottom of the barrel. At the same time, a sliding track is provided for the connecting box 26 to ensure that the scraper 27 moves smoothly along the barrel wall. The outer part of the rotating rod 5 is rotatably connected to the inside of the fixed box 3, and the bottom end of the rotating rod 5 is fixedly connected to the top of the bottom plate 20. The inside of the connecting box 26 is slidably connected to the scraper 27. The scraper 27 is slidably connected to the inside of the connecting box 26, and the cutting edge is consistent with the curvature of the inner wall of the mixing barrel. When the connecting box 26 rotates, it scrapes close to the barrel wall to scrape the adhered material into the barrel to prevent material residue from affecting the preparation accuracy of the thermal conductive gel. Its material is wear-resistant and can withstand long-term friction.The scraper 27 is internally fixedly connected to a plurality of telescopic rods 28, which are evenly distributed between the scraper 27 and the connecting box 26. The internal piston is retractable, and the external spring 29 is mounted. When the scraper 27 contacts the barrel wall, the telescopic rod 28 is compressed and shortened. The elastic force of the spring 29 ensures that the scraper 27 always fits the barrel wall, adapting to the curvature changes of the inner wall of mixing barrels of different sizes. The external sleeve of the telescopic rod 28 is provided with a spring 29, which is mounted on the outside of the telescopic rod 28. The two ends of the spring 29 are respectively connected to the scraper 27 and the connecting box 26. The gap between the scraper 27 and the barrel wall is compensated by elastic deformation, ensuring uniform contact force, preventing damage to the scraper 27 or the barrel wall due to rigid contact, and at the same time cushioning the impact of materials during the mixing process. Reference Figure 1 and Figure 8 The inner sliding connection of the operation box 1 is connected with a load-bearing plate 30, which is slidably connected to the inner part of the operation box 1, carrying the mixing barrel at the top and connected to the lifting mechanism at the bottom. It can be moved up and down by the staff operation, and the mixing barrel can be accurately positioned to the bottom end of the limit cover 2 to ensure that the material in the barrel is aligned with the mixing assembly. At the same time, a stable support plane is provided. The inner rotation of the load-bearing plate 30 is connected with a two-way threaded rod 31. The two-way threaded rod 31 passes through the middle of the load-bearing plate 30, and the threads at both ends rotate in opposite directions. When rotating, it drives the clamping plates 33 on both sides to move synchronously toward the center or outside, and converts the rotational motion into linear motion of the clamping plates 33 through thread transmission, so as to realize rapid clamping and loosening of mixing barrels of different diameters. The inner fixed connection of the load-bearing plate 30 is limited. The limit rod 32 is fixed inside the load-bearing plate 30, parallel to the two-way threaded rod 31, and passes through the internal through hole of the clamping plate 33 to limit the rotation of the clamping plate 33. The cam 33 is fixed on the outside of the two-way threaded rod 31 and the rubber block 34 is fixed on the inside. When the two-way threaded rod 31 rotates and moves toward the center, the rubber block 34 contacts the outer wall of the mixing barrel and clamps the barrel body with friction to prevent the barrel body from shifting due to vibration or centrifugal force during the mixing process. It is suitable for mixing barrels of different specifications. The inside of the clamping plate 33 is fixedly connected to the rubber block 34. The rubber block 34 is fixed on the inside of the clamping plate 33. The surface is rough and elastic. When clamping the mixing barrel, the contact friction is increased and the clamping force is buffered to avoid deformation of the barrel body caused by rigid clamping, thereby improving the reliability of the mixing barrel fixation and the compatibility of the equipment. The inside of the clamping plate 33 is slidably connected to the outside of the limit rod 32.

The mixing barrel is positioned and fixed by the movement of the clamping plates 33, and the friction force is increased by the rubber block 34. The staff operates the operating box 1 to raise and lower the bearing plate 30, and raise and lower the top of the mixing barrel to coincide with the bottom end of the limit cover 2. The bottom end of the sliding rod 21 contacts The bottom end of the inner wall of the mixing barrel is caused to slide inside the rotating rod 5, and the sliding of the sliding rod 21 drives the outer side of the limiting plate 22 to slide in the groove inside the rotating rod 5 and the rotating ring 11, and the sliding of the limiting plate 22 drives the rotation of the rotating plate 23, and the rotation of the rotating plate 23 drives the movement of the connecting box 26.

[0031] By simultaneously starting motor 1 4 and motor 2 13 so that their rotation speed and direction are the same, starting motor 1 4 drives the rotation of rotating rod 5, and the rotation of rotating rod 5 drives the rotation of bottom plate 20, and the rotation of rotating rod 5 drives the rotation of output gear 1 6, and the rotation of output gear 1 6 drives output gear 2 8 to rotate inside fixed box 3. The interior of fixed box 3 is provided with a groove to mesh with output gear 2 8, and the rotation of output gear 2 8 drives the rotation of rotating column 7 and stirring blade 9. The rotation of stirring blade 9 stirs the internal material of the mixing barrel, and the rotation of motor 2 13 drives the rotation of worm 14, and the rotation of worm 14 drives the rotation of turbine 12, and the rotation of turbine 12 drives the rotation of rotating ring 11. The rotation of the rotating ring 11 drives the rotation of the bevel gear 16, the fixed plate 10 and the limit plate 22. The function of the fixed plate 10 is to protect and limit multiple internal structures. The rotation of the bevel gear 16 drives the rotation of the rotating plate 23. The rotation of the bottom plate 20 and the rotating plate 23 drives the rotation of the connecting box 26 and the scraper 27 to alternate the materials on the inner wall of the mixing barrel.
