Abstract
Description
Technical Field
[0001] This application relates to the field of thermal paste coating technology, and in particular to a thermal paste coating device. Background Technology
[0002] In the assembly and production of electronic equipment, the application of thermal paste to heat sinks is a crucial step in ensuring the heat dissipation performance of the equipment. In actual production, the thermal paste on heat sinks may expire due to prolonged storage, requiring reapplication to restore its heat dissipation performance.
[0003] Currently, replacing thermal paste on radiators is typically done manually. This involves manually scraping off expired thermal paste and then applying new paste using a screen printing jig and scraper. Manual operation requires processing each radiator individually, and the process is tedious, involving multiple steps such as scraping off the old paste, placing the screen printing jig, and digging and applying the new paste, resulting in low efficiency. During manual operation, workers frequently come into contact with the thermal paste, which can easily become sticky on their hands and contaminate the radiator itself. This contamination not only affects the radiator's heat dissipation performance but can also lead to customer complaints and increased after-sales costs. Utility Model Content

[0061] Radiator 200. Detailed Implementation
[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0063] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0064] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the thermal paste coating device and heat sink provided in the embodiments of this application.
[0065] In a first specific embodiment, the thermal paste coating device 100 provided in this application mainly includes a positioning component 1, a guiding component 2, and a paste storage component 3. The positioning component 1 has a plurality of linearly arranged mounting positions 101, which are used to position the heat sink 200. The guiding component 2 is disposed on the positioning component 1, and the extending direction of the guiding component 2 is the same as the arrangement direction of the plurality of mounting positions 101. The paste storage component 3 is slidably connected to the guiding component 2, and the sliding range of the paste storage component 3 covers all mounting positions 101. The paste storage component 3 is used to coat the heat sink 200 in the mounting positions 101 with thermal paste.
[0066] To address the issues of low efficiency and contamination risk associated with manual application of thermal paste, the thermal paste application device 100 provided in this application achieves efficient and precise application of thermal paste to multiple heat sinks 200 through the coordinated design of positioning component 1, guiding component 2, and paste storage component 3. This effectively improves the application efficiency and reduces the risk of thermal paste contaminating the heat sinks 200 during manual operation.
[0067] Specifically, the positioning component 1 has multiple linearly arranged mounting positions 101, which are used to precisely position the heat sinks 200, ensuring that each heat sink 200 is in the correct position during the coating process. This design allows the device to process multiple heat sinks 200 simultaneously, thereby significantly improving coating efficiency and solving the problem of low efficiency caused by manually processing each heat sink 200 one by one.
[0068] The guide component 2 is located on the positioning component 1, and its extension direction is consistent with the arrangement direction of the mounting positions 101, providing a stable movement path for the paste storage component 3. The paste storage component 3 is slidably connected to the guide component 2, and its sliding range covers all mounting positions 101. This means that the paste storage component 3 can move precisely along the arrangement direction of the mounting positions 101 under the guidance of the guide component 2, sequentially applying thermal paste to each heat sink 200. This sliding connection design not only improves the accuracy of the coating but also avoids the risk of thermal paste contamination of the heat sink 200 due to improper operation during manual processing.
[0069] By utilizing the multi-mounting position 101 design of the positioning component 1, the device can perform coating operations on multiple heat sinks 200 simultaneously, significantly improving work efficiency. Simultaneously, the precise guidance of the guiding component 2 and the sliding coating function of the paste storage component 3 ensure that the thermal paste is uniformly and accurately applied to the heat sink 200, reducing waste and contamination caused by manual operation. Therefore, the thermal paste coating device 100 of this application not only improves coating efficiency but also effectively reduces the risk of thermal paste contamination of the heat sink 200 during manual operation, addressing the main deficiencies in related technologies.
[0070] Based on the above structural and process descriptions, it can be seen that the thermal paste coating device 100 has at least the following beneficial effects: Through the coordinated design of the positioning component 1, the guiding component 2, and the paste storage component 3, the thermal paste coating device 100 achieves efficient and precise thermal paste coating on multiple heat sinks 200, effectively improving coating efficiency and reducing the risk of thermal paste contaminating the heat sinks 200 during manual operation.
[0071] Please refer to Figure 2 , Figure 2 This is a schematic diagram of a thermal paste coating device provided in an embodiment of this application.
[0072] In some embodiments, the positioning component 1 includes:
[0073] The base 11 is provided with a mounting position 101;
[0074] Support structure 12 is provided on base 11 and is movably connected to guide component 2.
[0075] In this embodiment, the positioning component 1, as an important part of the thermal paste coating device 100, mainly consists of a base 11 and a support structure 12. The base 11 has multiple mounting positions 101, which are used to precisely position the heat sink 200, ensuring that the heat sink remains stable and in the correct position during the coating process. The support structure 12 is disposed on the base 11 and forms a movable connection with the guide component 2. This movable connection design gives the guide component 2 the ability to adjust relative to the support structure 12, thereby allowing the guide component 2 to be flexibly positioned on the positioning component 1.
[0076] Through its movable connection design, the guide assembly 2 can be moved or rotated relative to the support structure 12, thereby achieving multiple functions. For example, when it is necessary to place or remove the radiator 200 into or from the mounting position 101 of the base 11, the guide assembly 2 can be moved or rotated to a position that does not affect the placement or removal of the radiator. This design not only improves the ease of operation of the device but also ensures that the radiator 200 can be smoothly prepared for coating and removed after coating. In addition, the movable connection also facilitates the maintenance and cleaning of the device, allowing the guide assembly 2 to be quickly disassembled or adjusted as needed, further enhancing the practicality and flexibility of the device.
[0077] In some cases, the mounting position 101 adopts a recessed groove to facilitate the positioning of the heat sink 200. After the heat sink 200 is positioned, the heat transfer paste is applied to the heat sink 200 by the movement of the paste storage component 3 on the guide component 2 and the release of thermal paste by the paste storage component 3.
[0078] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the positioning component provided in an embodiment of this application.
[0079] In some embodiments, the support structure 12 includes:
[0080] Support 121 is located on base 11;
[0081] The connector 122 has a connecting end 1221 and an adjusting end 1222 connected together. The connecting end 1221 is movably connected to the guide component 2, and the adjusting end 1222 is connected to the support column 121. The connection position between the adjusting end 1222 and the support column 121 is adjustable.
[0082] In this embodiment, the design of the support structure 12 provides the thermal paste coating device 100 with flexible adjustment capabilities to accommodate heat sinks 200 of different specifications and sizes. The support structure 12 mainly includes a support column 121 and a connector 122. The support column 121 is fixedly mounted on the base 11, providing a stable support foundation for the entire support structure 12. The connector 122 is movably connected to the guide component 2 through its connecting end 1221. This movable connection allows the guide component 2 to be adjusted in position or orientation as needed, thereby better adapting to the coating requirements of the heat sink 200.
[0083] The adjusting end 1222 of the connector 122 is connected to the support column 121, and its connection position is adjustable. This design feature allows the adjusting end 1222 to be moved and adjusted on the support column 121, thereby achieving flexible adjustment of the position of the guide component 2. This adjustability provides the device with a high degree of adaptability, enabling precise adjustments according to the specific size and installation position of the heat sink 200, ensuring the stability and accuracy of the thermal paste application process. For example, when the height of the heat sink 200 changes, by adjusting the position of the adjusting end 1222 on the support column 121, the relative positional relationship between the guide component 2 and the heat sink 200 can be optimized, thereby ensuring the smooth progress of the coating operation.
[0084] Furthermore, this embodiment does not limit the movable connection method between the guide component 2 and the connecting end 1221, which provides greater flexibility in the design and use of the device. The guide component 2 can move relative to the connecting end 1221 through a sliding connection, or it can adjust its angle through a rotational connection. This diverse connection method further enhances the adaptability and ease of operation of the device, enabling it to better meet the usage needs in different scenarios.
[0085] In some cases, the connecting end 1221 is provided with a pair of clamping arms, and a clamping hole is formed between the pair of clamping arms that can be fitted onto the support column 121. The pair of clamping arms are locked by fasteners, thereby locking the support column 121 in the clamping hole, so as to realize the locking and fixing of the connecting end 1221 of the connector 122 on the support column 121.
[0086] In some embodiments, the guide component 2 is located above the positioning component 1;
[0087] The guide assembly 2 is rotatably connected to the positioning assembly 1, and the guide assembly 2 can rotate in a direction away from the mounting position 101.
[0088] In this embodiment, the design of the guide component 2 significantly facilitates the operation of the thermal paste coating device 100. The guide component 2 is located above the positioning component 1 and is connected to the positioning component 1 by a rotatable connection. This structural design allows the guide component 2 to rotate away from the mounting position 101, thereby enabling flexible operation and adjustment during the coating process.
[0089] Specifically, the guide assembly 2 is rotatably connected to the connecting end 1221 of the connector 122 in the positioning assembly 1 via a pin. This connection method not only ensures the stability of the guide assembly 2 on the positioning assembly 1, but also gives it flexible rotation capability. Before the coating operation, the operator can rotate the guide assembly 2 to one side, thereby fully exposing the mounting position 101 on the base 11. At this time, the heat sink 200 can be easily placed into the mounting position 101 without complicated operations in a narrow space, greatly improving the convenience and efficiency of the operation.
[0090] After the heat sink 200 is placed, the operator rotates the guide component 2 back to its initial position, allowing it to work in conjunction with the positioning component 1 to prepare for the subsequent application of thermal paste. This rotating design of the guide component 2 not only facilitates the placement of the heat sink 200 but also provides stable support and precise guidance for the coating process, ensuring that the thermal paste can be applied evenly and accurately to the heat sink 200.
[0091] After coating, the guide assembly 2 is rotated to one side again, exposing the mounting position 101, allowing the heat sink 200 to be easily removed. This process not only simplifies the operation but also reduces potential risks caused by frequent movement of the heat sink 200, such as accidental contamination of the thermal paste or damage to the heat sink 200. Through this ingenious design, the rotation function of the guide assembly 2 significantly improves the operational efficiency and practicality of the entire thermal paste coating device 100, enabling it to better adapt to the actual needs of the production environment.
[0092] Please continue to refer to this. Figure 2 In some embodiments, the guide component 2 includes:
[0093] Guide seat 21 is provided on positioning component 1;
[0094] A screen printing plate 22 is provided on a guide seat 21. The screen printing plate 22 has a plurality of screen printing holes 221, which are correspondingly provided with mounting positions 101.
[0095] The limiting structure 23 is located on the guide seat 21 and is slidably connected to the paste storage component 3.
[0096] In this embodiment, the design of the guide assembly 2 achieves efficient and precise control of the thermal paste coating process through the synergistic effect of its various components. The guide assembly 2 mainly includes a guide seat 21, a screen printing plate 22, and a limiting structure 23, which together constitute a fully functional coating guide system.
[0097] The guide seat 21, as the basic structure of the guide assembly 2, is fixedly installed on the positioning assembly 1, providing stable support and accurate positioning for the entire guide assembly 2. It not only supports the screen printing plate 22 and the limiting structure 23, but also ensures that the relative position of the entire guide assembly 2 with the positioning assembly 1 remains stable during the coating process, thus providing a basic guarantee for the uniform coating of thermal paste.
[0098] The screen printing plate 22, mounted on the guide seat 21, is a key component for achieving precise application of thermal paste. The screen printing plate 22 has multiple printing holes 221, each corresponding to a mounting position 101 on the positioning assembly 1. This correspondence ensures that during the coating process, when the paste storage assembly 3 slides on the screen printing plate 22 and reaches the position of the printing hole 221, the thermal paste can accurately pass through the printing hole 221 and be evenly applied to the heat sink 200 below the printing hole 221. Because the printing holes 221 correspond one-to-one with the mounting positions 101, the paste storage assembly 3 can sequentially complete the thermal paste application to all heat sinks 200 during its sliding process, greatly improving coating efficiency and accuracy.
[0099] The limiting structure 23 is also mounted on the guide seat 21 and forms a sliding connection with the paste storage assembly 3. The function of the limiting structure 23 is to provide precise guidance and limiting for the sliding of the paste storage assembly 3. During the movement of the paste storage assembly 3, the limiting structure 23 ensures that it slides smoothly along a predetermined trajectory, avoiding problems such as uneven or failed coating of thermal paste due to deviation or jitter during the sliding process. With the support of the limiting structure 23, the paste storage assembly 3 can slide stably on the screen printing plate 22 and accurately release thermal paste when it reaches each screen printing hole 221, thereby achieving continuous and uniform coating of multiple heat sinks 200.
[0100] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the guide assembly and slider provided in an embodiment of this application.
[0101] In some embodiments, the limiting structure 23 includes a pair of sliding shafts 231, which are located on the same side of the screen printing plate 22 and are spaced apart with the screen printing holes 221 as the center.
[0102] The ointment storage component 3 includes a slider 31, which is slidably connected to a pair of sliding shafts 231.
[0103] In this embodiment, the specific design of the limiting structure 23 further optimizes the coating accuracy and stability of the thermal paste coating device 100. The limiting structure 23 includes a pair of sliding shafts 231, which are located on the same side of the screen printing plate 22 and spaced apart with the screen printing holes 221 as the center. This layout allows the sliding shafts 231 to provide precise guidance and stable support for the sliding of the paste storage assembly 3.
[0104] The slider 31 in the thermal paste application assembly 3 is slidably connected to the pair of sliding shafts 231. Specifically, the slider 31 has holes that match the sliding shafts 231, and the pair of sliding shafts 231 pass through the corresponding holes on the slider 31. This design not only ensures the stability of the slider 31 during sliding, but also prevents the slider 31 from shifting or wobbling during movement through the limiting effect of the sliding shafts 231, thereby ensuring that the thermal paste can be accurately applied to the heat sink 200 through the screen printing holes 221.
[0105] With this structural design, the slider 31 can move smoothly along the trajectory of the sliding shaft 231 during sliding, ensuring that the movement trajectory of the paste storage assembly 3 precisely corresponds to the position of the screen printing hole 221. When the slider 31 moves to the position of the screen printing hole 221, the thermal paste can accurately pass through the screen printing hole 221 and be evenly applied to the heat sink 200. This precise sliding connection method not only improves the coating accuracy but also enhances the reliability and repeatability of the device, making the thermal paste coating process more stable and efficient.
[0106] Furthermore, the spacing of the sliding shafts 231 and the hole design of the slider 31 provide sufficient freedom for the movement of the paste storage assembly 3, while the constraint of the limiting structure 23 ensures the accuracy and consistency of the movement. This design not only guarantees coating accuracy but also improves the adaptability and flexibility of the device, enabling it to better meet the coating needs of heat sinks 200 of different specifications.
[0107] Please refer to Figure 5 , Figure 5 This is a schematic diagram of a screen printing plate provided in an embodiment of this application.
[0108] In some embodiments, the screen printing plate 22 is provided with a groove 222, which surrounds the screen printing hole 221.
[0109] In this embodiment, the design of the screen printing plate 22 incorporates a recessed groove 222 to further optimize the uniformity of the thermal paste coating and the structural stability of the screen printing plate 22. The recessed groove 222 is disposed on the screen printing plate 22 and surrounds the screen printing holes 221. The main purpose of this design is to enhance the overall rigidity of the screen printing plate 22 by increasing its thickness, thereby preventing deformation due to uneven stress or external forces during the coating process.
[0110] The groove 222 can be located on the side of the screen printing plate 22 facing the heat sink 200, and its function is to provide a space constraint for the thermal paste during the coating process. When the paste storage assembly 3 squeezes the thermal paste onto the heat sink 200 through the screen printing holes 221, the groove 222 ensures that the thermal paste is evenly distributed within the defined space. This space constraint allows the thermal paste to cover the surface of the heat sink 200 more evenly, avoiding a decrease in heat dissipation performance due to thermal paste accumulation or uneven distribution.
[0111] In summary, the introduction of the sink 222 not only enhances the structural rigidity of the screen printing plate 22 and avoids the impact of deformation on the coating accuracy, but also ensures the uniform coating of thermal paste on the heat sink 200 through space restriction, thereby improving the performance and stability of the entire thermal paste coating device.
[0112] In some embodiments, the paste storage component 3 includes:
[0113] Slider 31 is slidably connected to guide component 2;
[0114] Handle 32 is located on slider 31;
[0115] The paste storage structure 33 is located on the slider 31. The paste storage structure 33 has a communicating paste storage cavity 3311 and paste outlet 3312.
[0116] In this embodiment, the design of the paste storage component 3 provides the thermal paste coating device 100 with efficient coating function and convenient operation experience. The paste storage component 3 mainly includes a slider 31, a handle 32, and a paste storage structure 33.
[0117] The slider 31 is the core component of the paste storage assembly 3, and it is slidably connected to the sliding shaft 231 in the guide assembly 2. This connection method not only ensures that the paste storage assembly 3 can move smoothly under the guidance of the guide assembly 2, but also allows the paste storage assembly 3 and the guide assembly 2 to be flipped as a whole. This design provides great convenience for the placement and removal of the heat sink 200, allowing the operator to easily put or take out the heat sink 200 into or out of the mounting position 101 before and after coating.
[0118] The handle 32 is mounted on the slider 31, providing a convenient operating interface for the operator. Through the handle 32, the operator can easily control the movement of the paste storage component 3, as well as the overall flipping guide component 2 and the paste storage component 3. This design not only improves operational convenience but also reduces the potential risk of damage to the radiator 200 during operation, further enhancing the practicality and reliability of the device.
[0119] The thermal paste storage structure 33 is also mounted on the slider 31, and its interior has a communicating storage cavity 3311 and a discharge port 3312. Thermal paste is first loaded into the storage cavity 3311 of the storage structure 33. During the coating process, the storage assembly 3 moves along the sliding shaft 231 driven by the slider 31 to each screen printing hole 221 of the screen printing plate 22. At this time, the thermal paste flows out through the discharge port 3312 and is evenly coated onto the heat sink 200 below through the screen printing holes 221. This design ensures that the thermal paste can accurately reach the designated position on the heat sink 200, while avoiding waste and contamination of the thermal paste.
[0120] It is important to note that the connection between slider 31 and slide shaft 231 not only supports the sliding function of paste storage component 3, but also allows paste storage component 3 and guide component 2 to be rotated as a whole. The ingenuity of this design lies in the fact that while ensuring coating accuracy, it also provides great convenience for the placement and removal of heat sink 200, making the entire coating process more efficient and smooth.
[0121] Please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the paste storage structure provided in the embodiments of this application. Figure 7 This is a schematic diagram of a paste storage component provided in an embodiment of this application.
[0122] In some embodiments, the paste-holding structure 33 includes:
[0123] The ointment storage component 331 is hollow inside to form an ointment storage cavity 3311. The bottom of the ointment storage component 331 is provided with an ointment outlet 3312, and the top of the ointment storage component 331 is provided with an installation port 3313, which communicates with the ointment storage cavity 3311.
[0124] The pressing mechanism 332 is detachably connected to the mounting port 3313. The pressing mechanism 332 can apply pressure to the thermal conductive paste in the paste storage chamber 3311, driving the thermal conductive paste to flow to the paste outlet 3312.
[0125] In this embodiment, the design of the paste storage structure 33 further optimizes the storage and application efficiency of the thermal paste, while improving the flexibility and ease of operation of the device. The paste storage structure 33 mainly includes a paste storage component 331 and a paste pressing mechanism 332.
[0126] The paste storage component 331 is the core component of the paste storage structure 33. Its interior is hollow, forming a paste storage cavity 3311 for containing the thermal paste. The bottom of the paste storage component 331 has a paste outlet 3312 for guiding the thermal paste to the application position; the top has an installation port 3313, which communicates with the paste storage cavity 3311 and is used to connect to the paste pressing mechanism 332. It also serves as a filling port for the thermal paste. This design not only ensures smooth flow of the thermal paste but also facilitates the maintenance and refilling of the device.
[0127] The pressing mechanism 332 is detachably connected to the mounting port 3313 of the paste storage component 331. Its main function is to apply pressure to the thermally conductive paste in the paste storage cavity 3311, thereby driving the thermally conductive paste to flow towards the paste outlet 3312. This pressure application not only accelerates the flow rate of the thermally conductive paste but also ensures the continuity and uniformity of the coating process. The pressing mechanism 332 can apply pressure mechanically, such as through a spring or lever mechanism, or pneumatically, such as using a cylinder or air pump. This embodiment does not limit the specific pressure application method to adapt to different application scenarios and operational requirements.
[0128] The design of the mounting port 3313 facilitates the connection of the grease applicator 332 and also provides a channel for filling the thermal paste. When it is necessary to replace or replenish the thermal paste, the grease applicator 332 can be easily removed, and the thermal paste can be loaded into the paste storage chamber 3311 through the mounting port 3313. This design not only improves the flexibility of the device but also reduces the potential risk of failure caused by frequent disassembly and reassembly. The connection between the mounting port 3313 and the grease applicator 332 can be a snap-fit, threaded, or other detachable connection method. This embodiment does not limit the specific connection method to adapt to different design requirements and operating habits.
[0129] In some embodiments, the bottom of the paste storage component 331 is provided with a boss 3314, which cooperates with the slider 31 and surrounds the paste outlet 3312.
[0130] In this embodiment, the design of the paste storage component 331 further optimizes the structural stability and functional integration of the paste storage assembly 3. The bottom of the paste storage component 331 is provided with a boss 3314. This structural feature fits tightly with the slider 31, making the installation of the paste storage component 331 on the slider 31 more stable, and also providing more precise guidance for the flow of thermal paste.
[0131] The design of the boss 3314 not only enhances the connection strength between the paste storage component 331 and the slider 31, but also ensures that the thermal paste is accurately guided to the coating position when it flows out of the paste storage cavity 3311 through its surrounding structure of the paste outlet 3312. This design avoids uneven coating caused by positional deviation or diffusion of the thermal paste during the outflow process, thereby improving the accuracy and quality of coating.
[0132] Furthermore, the cooperation between the boss 3314 and the slider 31 provides more stable support for the overall movement of the thermal paste storage assembly 3. When the thermal paste storage assembly 3 slides along the sliding shaft 231 or undergoes an overall flipping operation, the boss 3314 can effectively reduce thermal paste leakage or positional displacement caused by vibration or impact, further enhancing the reliability and durability of the device.
[0133] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the paste-pressing mechanism provided in an embodiment of this application.
[0134] In some embodiments, the paste-applying mechanism 332 includes:
[0135] Mounting component 3321 is detachably connected to mounting port 3313. The interior of mounting component 3321 is hollow. Mounting component 3321 is provided with a sliding groove 33211 that communicates with its interior. Mounting component 3321 is also provided with a notch 33212 that communicates with the sliding groove 33211.
[0136] Piston rod 3322 is slidably disposed inside mounting part 3321. Piston rod 3322 is provided with piston 33221, and pressure is applied to heat-conducting grease through piston 33221.
[0137] The elastic element 3323 is located inside the mounting member 3321. The elastic element 3323 is connected to the piston rod 3322. The elastic element 3323 is used to drive the piston rod 3322 to move toward the paste storage member 331.
[0138] A pull rod 3324 is connected to a piston rod 3322. The pull rod 3324 is located in a slide groove 33211. The pull rod 3324 can be engaged with a notch 33212 to lock the position of the piston rod 3322.
[0139] In this embodiment, the design of the paste-pressing mechanism 332 provides the paste storage structure 33 with an efficient thermal paste pressurization function, while also taking into account operational flexibility and reliability. The paste-pressing mechanism 332 mainly includes a mounting component 3321, a piston rod 3322, an elastic component 3323, and a pull rod 3324.
[0140] The mounting component 3321 is detachably connected to the mounting port 3313 of the paste storage component 331. Its interior is hollow, providing space for the movement of the piston rod 3322. The mounting component 3321 has a sliding groove 33211 inside to guide the movement of the pull rod 3324. The mounting component 3321 also has a notch 33212 communicating with the sliding groove 33211 to lock the position of the pull rod 3324.
[0141] The piston rod 3322 is slidably disposed inside the mounting component 3321, and a piston 33221 is provided at its end. When the piston rod 3322 moves downward, the piston 33221 enters the paste storage chamber 3311 of the paste storage component 331, and the thermal paste is squeezed out from the paste outlet 3312 by applying downward pressure, thereby realizing the coating of thermal paste.
[0142] The elastic element 3323 is disposed inside the mounting member 3321 and connected to the piston rod 3322. In this embodiment, the elastic element 3323 is a spring, which provides a downward elastic force to the piston rod 3322. When the elastic element 3323 is in its natural state, the piston rod 3322 maintains a downward tendency under the action of the spring, so that the piston 33221 can continuously apply pressure to the thermal paste in the paste storage cavity 3311, ensuring that the thermal paste can flow smoothly to the paste outlet 3312.
[0143] The pull rod 3324 is connected to the piston rod 3322 and is located in the groove 33211. The position of the piston rod 3322 can be controlled by operating the pull rod 3324. When it is necessary to release the pressure on the thermal paste, the operator can pull the pull rod 3324 upwards, causing the piston rod 3322 to move upwards against the elastic force of the elastic element 3323, further pushing the pull rod 3324 into the notch 33212. The pull rod 3324 will then be locked within the notch 33212, thus locking the position of the piston rod 3322. At this time, the piston 33221 no longer applies pressure to the thermal paste, and the flow of the thermal paste is suspended.
[0144] This design not only enables precise control of the pressure applied to the thermal paste, but also improves the operational flexibility and maintenance convenience of the paste application mechanism 332 through a detachable connection and locking mechanism. Operators can quickly switch the coating state of the thermal paste according to actual needs, and can easily disassemble the mounting part 3321 to perform the corresponding operations when it is necessary to replenish or replace the thermal paste.
[0145] In some cases, an end cap is provided on the top of the mounting component 3321. The end cap is connected to the body of the mounting component 3321 by threads. When the end cap is removed, parts such as the piston rod 3322 and the elastic element 3323 can be inserted from the top of the mounting component 3321.
[0146] Please refer to Figure 9 , Figure 9 This is a schematic diagram of a sealing plate provided in an embodiment of this application.
[0147] In some embodiments, the paste-holding structure 33 further includes:
[0148] A sealing plate 333 is movably mounted on the paste storage component 331. The sealing plate 333 is located on the side of the paste outlet 3312 facing the inside of the paste storage component 331. The sealing plate 333 is provided with a limiting hole 3331 and a through hole 3332. The through hole 3332 is used to allow the thermal conductive paste to flow out of the paste outlet 3312 through the sealing plate 333 when it is aligned with the paste outlet 3312.
[0149] A limiting member 334 is provided on the paste storage member 331. The limiting member 334 cooperates with the limiting hole 3331 to limit the movement range of the sealing plate 333.
[0150] In this embodiment, the design of the paste storage structure 33 further incorporates a sealing plate 333 and a limiting member 334 to achieve precise control and flexible adjustment of the thermal paste flow. This design not only enhances the functionality of the paste storage structure 33 but also improves the reliability and ease of operation of the entire thermal paste coating device.
[0151] The sealing plate 333 is movably disposed inside the paste storage component 331, located on the side of the paste outlet 3312 facing inwards from the paste storage component 331, essentially above the paste outlet 3312. The sealing plate 333 has a limiting hole 3331 and a through hole 3332. The through hole 3332 is aligned with the paste outlet 3312, allowing the thermal paste to flow out of the paste outlet 3312 through the sealing plate 333 when needed. This design provides a controllable channel for the outflow of the thermal paste, ensuring the accuracy and stability of the coating process.
[0152] A limiting member 334 is disposed on the paste storage member 331 and engages with the limiting hole 3331 on the sealing plate 333. The main function of the limiting member 334 is to restrict the movement range of the sealing plate 333, thereby achieving precise control over the flow of thermal paste. Within the movement range of the sealing plate 333, there is a specific position. When the limiting member 334 is pushed to this position, the through hole 3332 aligns with the paste outlet 3312. At this time, the sealing plate 333 does not obstruct the flow of thermal paste, and the thermal paste can flow out smoothly through the paste outlet 3312. Under other circumstances, the sealing plate 333 will cover the paste outlet 3312, which is equivalent to closing the flow channel of the thermal paste, thereby preventing the thermal paste from flowing out.
[0153] This design achieves a simple mechanical structure that switches the flow of thermal paste, preventing waste or contamination caused by accidental spillage. Simultaneously, the combined use of the sealing plate 333 and the limiting component 334 provides operators with an intuitive and reliable operating method, making the thermal paste coating process more controllable. By pushing the limiting component 334, operators can easily switch the flow state of the thermal paste, achieving precise flow control during coating. This design not only improves coating efficiency but also enhances the reliability and adaptability of the device, enabling it to better meet coating needs in different scenarios.
[0154] In one specific embodiment, the process of using the thermal paste coating device is described below.
[0155] When using the thermal paste coating apparatus 100 of this application for coating operations, the apparatus first needs to be prepared. Specifically, the sealing plate 333 is pushed to the right to close the thermal paste outflow channel, ensuring no leakage occurs during filling. Next, the paste storage assembly 3 is slid along the sliding shaft 231 to the leftmost position. At this time, the pull rod 3324 is pulled upwards and engaged in the notch 33212, causing the piston rod 3322 to rise to its initial position. Then, the paste pressing mechanism 332 is removed, and thermal paste is poured into the paste storage chamber 3311, ensuring sufficient filling. After filling, the paste pressing mechanism 332 is reinstalled, and the pull rod 3324 is released. At this time, the piston rod 3322, under the action of the elastic element 3323, presses down on the thermal paste, preparing for subsequent coating operations. Finally, the sealing plate 333 is pushed to the left to open the thermal paste outflow channel, and the apparatus enters the coating state.
[0156] After the device is prepared, the coating operation on the heat sink 200 begins. First, lift and flip the guide assembly 2 upwards, away from the mounting position 101 on the base 11, and place the heat sinks 200 to be coated with thermal paste one by one into the mounting positions 101 on the base 11, ensuring that the heat sinks 200 are stably and accurately positioned in the mounting positions 101. After placement, flip the guide assembly 2 downwards, returning it to its initial position. At this time, the guide assembly 2 and the positioning assembly 1 work together to provide stable support and precise guidance for the coating process.
[0157] Next, operate the paste storage assembly 3 using handle 32, slowly sliding it along the slide shaft 231 to the rightmost end. During this process, the paste outlet 3312 of the paste storage assembly 3 aligns sequentially with the screen printing holes 221 on the screen printing plate 22, and evenly applies the thermal paste onto the heat sink 200 through the screen printing holes 221. After application, lift and flip the guide assembly 2 again to expose the mounting position 101, and remove the heat sink 200 with the applied thermal paste. At this point, one thermal paste application operation is complete. To perform the next application, simply place the new heat sink 200 to be coated into the mounting position 101 and repeat the above steps. The entire process is simple to operate and can efficiently and accurately complete the thermal paste application task.
[0158] To further optimize the functionality and automation of the thermal paste coating device 100, this application proposes the following extended technical solutions, aiming to improve the accuracy and efficiency of the coating process through detection and control technologies.
[0159] A detector is installed on the positioning component 1 to detect the movement position of the paste storage component 3. Specifically, a first detector 102 and a second detector 103 are respectively installed at the first mounting position 101 and the last mounting position 101. The controller is signal-connected to these two detectors and achieves precise control of the coating process through signal feedback from the detectors.
[0160] When the paste storage assembly 3 moves to the first mounting position 101, the first detector 102 detects a signal and sends it to the controller. Upon receiving the signal, the controller determines that the paste storage assembly 3 has reached the starting position and then initiates the coating process, allowing the thermal paste to be applied to the heat sink 200 through the paste outlet 3312 and the screen printing hole 221. After completing the coating of the first heat sink 200, the paste storage assembly 3 continues to move along the sliding shaft 231. If the controller detects a signal from the second detector 103 before completing the coating of the first heat sink 200, it determines that the paste storage assembly 3 has started the coating operation before resetting, potentially indicating an incomplete coating task. In this case, the controller will issue an alarm or pause subsequent operations to avoid product quality problems caused by incomplete coating.
[0161] A detector is installed at each mounting position 101 of the positioning component 1, and the controller is connected to all detector signals. This design enables precise positioning and coating control of the paste storage component 3 at each mounting position 101.
[0162] Specifically, when the paste storage assembly 3 moves to any mounting position 101, the corresponding detector detects a signal and notifies the controller. The controller determines the position of the paste storage assembly 3 based on the detector signal and initiates the coating process. After completing the coating at the current mounting position 101, the controller records the coating status at that position and directs the paste storage assembly 3 to continue moving to the next mounting position 101. In this way, the controller can monitor the movement process of the paste storage assembly 3 in real time and ensure that each heat sink 200 undergoes a precise coating operation. In addition, the controller can also optimize the moving speed of the paste storage assembly 3 based on the detector signal to adapt to the coating requirements of different heat sinks 200, further improving coating efficiency and quality.
[0163] Based on Scheme 1 or Scheme 2, a timer function is further introduced to precisely control the coating operation time of each heat sink 200. The specific implementation method is as follows.
[0164] After the detector provides a signal, the controller starts a timer. The timer's duration is preset according to the coating requirements of the heat sink 200, ensuring that the coating time for each heat sink 200 is sufficient and uniform. For example, when the paste storage assembly 3 reaches the first mounting position 101, the first detector 102 detects a signal, the controller starts the timer, and begins the coating operation. Once the timer reaches the preset time, the controller immediately stops the coating action and directs the paste storage assembly 3 to move to the next mounting position 101. In this way, the coating time for each heat sink 200 is strictly controlled, avoiding quality problems caused by insufficient or excessive coating time.
[0165] Furthermore, the timer can be combined with a detector to achieve dual monitoring of the coating process. For example, if the paste storage component 3 moves to the next installation position 101 before the preset coating time has been reached, the controller will detect the anomaly and issue an alarm, prompting the operator to check the equipment status. This design not only improves the automation level of the coating process but also enhances the reliability and stability of the system, ensuring that each heat sink 200 achieves a high-quality coating effect.
[0166] In some cases, the thermal paste application device is a semi-automated device. Regarding the extended technical solutions for controllers, detectors, and timers, staff can be alerted to assess the situation through audible and visual alarms.
