Description

Technical Field

[0001] This utility model relates to the field of printed thermal adhesive technology, specifically a tooling for rapid printing of thermal adhesive. Background Technology

[0002] Printed thermal adhesive is an advanced manufacturing technology that precisely coats thermally conductive materials onto the contact surfaces between electronic components and heat dissipation structures using a printing process. This technology uses silicone, acrylate, or phase change materials as a matrix, mixed with fillers such as high thermal conductivity ceramic powder and metal oxides, to form a composite colloid that combines thermal conductivity, insulation, and adhesion. Its core advantage lies in achieving micron-level thickness control and complex shape adaptation through processes such as screen printing, spraying, or dispensing. This effectively fills the microscopic gaps between heat-generating components and heat sinks, reducing contact thermal resistance. Compared to traditional thermal grease, printed thermal adhesive has high-temperature resistance and anti-volatile properties, and does not produce silicone oil migration over long-term use, avoiding contamination of sensitive components. Compared to mechanical fixing methods, its adhesive strength increases with temperature, and it eliminates the need for screws or other auxiliary structures, simplifying the assembly process.

[0003] However, existing rapid printing thermal adhesive fixtures suffer from problems such as low coating efficiency, high labor costs, difficulty in uniformly controlling coating thickness, and unstable coating quality. Therefore, we need a rapid printing thermal adhesive fixture. Utility Model Content

[0004] The purpose of this invention is to provide a rapid printing fixture for thermal adhesive, in order to solve the existing problems of low coating efficiency, high labor costs, difficulty in uniformly controlling coating thickness, and unstable coating quality of the rapid printing fixture for thermal adhesive mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-printing heat dissipation adhesive fixture, including a scraper, a printing component mounted on one side of the scraper, a positioning frame on the top of the printing component, a steel sheet installed inside the positioning frame, a quick-release component inside the positioning frame, a positioning groove inside the positioning frame, a fixing frame including a fixing frame disposed on one side of the scraper, a connecting frame fixedly connected to one side of the fixing frame, a carrier plate fixedly connected to the top of the fixing frame, a groove on the top of the fixing frame, and a protrusion on the top of the fixing frame.

[0007] Preferably, the connecting frame forms a fixed structure with the carrier plate through the fixing frame, and one side of the fixing frame is fixed to one side of the connecting frame, and the top of the fixing frame is fixed to the bottom of the carrier plate.

[0008] Preferably, the quick-release assembly includes bolts, and the bolts are disposed inside the positioning frame. A fixing plate is fixedly connected inside the positioning frame. A support frame is fixedly connected to the bottom of the fixing plate. A slider is fixedly connected to the inner wall of the support frame. A spring is fixedly connected to the bottom of the fixing plate. A positioning plate is fixedly connected to one end of the spring. A locking block is fixedly connected to one side of the positioning plate. A sliding groove is provided on one side of the positioning plate.

[0009] Preferably, the positioning frame is a detachable structure formed by bolts and steel plates, and the bolts pass through the interior of the steel plates and the positioning frame for fixation.

[0010] Preferably, the support frame forms a sliding structure with a slider and a positioning plate, and the inner diameter of the groove matches the outer diameter of the slider, and the inner wall of the groove fits against the outer wall of the slider.

[0011] Preferably, the fixing plate and the positioning plate form an elastic structure through a spring, and the spring is disposed between the fixing plate and the positioning plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problems of low coating efficiency, high labor costs, difficulty in uniformly controlling coating thickness, and unstable coating quality in existing rapid printing thermal adhesive fixtures, this application constructs a highly efficient and precise printing system by setting up components such as a carrier plate, a fixing frame, a positioning frame, a steel sheet, and a scraper. After the product is moved to the carrier plate, the positioning frame drives the steel sheet to move, so that the protrusion of the steel sheet engages with the groove of the fixing frame, ensuring that the hollow part of the steel sheet is precisely aligned with the printing area of ​​the product. Then, thermal adhesive is squeezed in and quickly scraped with a scraper, thereby improving coating efficiency, reducing labor costs, effectively controlling the uniformity of coating thickness, and significantly improving coating quality. 2. To address the problems of unstable fixing, complex operation, and difficulty in adapting to different specifications of steel sheets in existing rapid printing heat dissipation adhesive fixtures, this application achieves rapid installation and reliable fixing of steel sheets by setting up an elastic fixing mechanism including a locking block, a positioning plate, a spring, and a sliding groove. During installation, the steel sheet is pushed into the positioning frame through the positioning groove, and the locking block compresses the spring of the positioning plate, causing it to slide along the sliding groove. After the steel sheet is in place, the spring resets and drives the locking block to press down and lock, and then bolts are used for secondary reinforcement. During disassembly, simply loosen the bolts and lift the locking block to allow the steel sheet to slide out smoothly, thus efficiently completing the replacement and installation of steel sheets of different thicknesses or styles.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model embodiment provides a tooling for rapid printing of thermal adhesive, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the device includes a squeegee 1, a printing assembly 2 mounted on one side of the squeegee 1, a positioning frame 3 on the top of the printing assembly 2, a steel plate 4 installed inside the positioning frame 3, a quick-release assembly 5 inside the positioning frame 3, and a positioning groove 6 inside the positioning frame 3. The printing assembly 2 includes a fixing frame 201, which is located on one side of the squeegee 1. A connecting frame 202 is fixedly connected to one side of the fixing frame 201, and a carrier plate 203 is fixedly connected to the top of the fixing frame 201. A groove 204 is formed on the top of the fixing frame 201. A protrusion 205 is provided on the top. By moving the product, the product is placed on the carrier plate 203. Then, the positioning frame 3 is moved, which causes the steel plate 4 and the protrusion 205 to move, so that the protrusion 205 engages with the groove 204 on the fixing frame 201, so that the hollow part on the steel plate 4 is aligned with the part on the product that needs to be printed. Then, heat dissipation adhesive is squeezed into the steel plate 4. The scraper 1 is picked up from the connecting frame 202 and the heat dissipation adhesive is quickly scraped onto the surface of the product with the scraper 1, so that the thickness of the adhesive is uniform and the adhesive is applied quickly, thereby completing the heat dissipation adhesive printing on the product.

[0017] Further such as Figure 2 and Figure 3 As shown, the positioning frame 3 forms a locking structure with the fixing frame 201 through the protrusion 205, and the inner diameter of the groove 204 matches the outer diameter of the protrusion 205. The inner wall of the groove 204 fits against the outer wall of the protrusion 205. With the protrusion 205 fixed by the positioning frame 3, the outer wall of the protrusion 205 can engage with the inner wall of the groove 204, which effectively enhances the connection stability between components, prevents loosening and displacement, ensures tight fit of the overall structure, ensures stable and reliable operation of the equipment or device, and is beneficial for printing products.

[0018] Further such as Figure 2 As shown, the connecting frame 202 forms a fixed structure with the carrier plate 203 through the fixing frame 201. One side of the fixing frame 201 is fixed to one side of the connecting frame 202, and the top of the fixing frame 201 is fixed to the bottom of the carrier plate 203. With the fixing frame 201, the carrier plate 203 can be fixed by the fixing of the connecting frame 202, which can ensure that the carrier plate 203 is in a precise and stable position, avoid its shaking or displacement, ensure the orderly and accurate operation of the overall structure, and facilitate the printing of products.

[0019] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the quick-release assembly 5 includes a bolt 501, which is located inside the positioning frame 3. A fixing plate 502 is fixedly connected inside the positioning frame 3. A support frame 503 is fixedly connected to the bottom of the fixing plate 502. A slider 504 is fixedly connected to the inner wall of the support frame 503. A spring 505 is fixedly connected to the bottom of the fixing plate 502. A positioning plate 507 is fixedly connected to one end of the spring 505. A locking block 506 is fixedly connected to one side of the positioning plate 507. A groove 508 is provided on one side of the positioning plate 507. By moving the steel plate 4, the steel plate 4 is inserted into the positioning frame 3 through the positioning groove 6. During the insertion process, the steel plate 4 presses the locking block 506, causing the locking block 506 to move the positioning plate 507 upward. The positioning plate 507 compresses the spring 505, causing elastic deformation. This allows the sliding groove 508 on the positioning plate 507 to slide on the slider 504 on the support frame 503. This allows the steel sheet 4 to pass through the locking block 506 and enter the positioning frame 3. The spring 505 then returns to its original position, causing the positioning plate 507 to move the locking block 506 downwards. The bottom of the locking block 506 then presses and fixes the steel sheet 4 in place. The locking block 506 then secures the steel sheet 4 to the positioning frame 3 using two bolts 501. To remove the steel sheet 4, first remove the two bolts 501, then pull the upward locking block 506 to allow the steel sheet 4 to slide out of the positioning groove 6, thus completing the removal of the steel sheet 4. This process allows for the installation of steel sheets 4 of different thicknesses or styles.

[0020] Further such as Figure 1 and Figure 4 As shown, the positioning frame 3 is detachable from the steel plate 4 by bolts 501, and the bolts 501 pass through the interior of the steel plate 4 and the positioning frame 3 for fixation. By setting the bolts 501, the positioning frame 3 and the steel plate 4 can be fixed, effectively preventing relative displacement between the positioning frame 3 and the steel plate 4, ensuring the stable connection between the two, and thus ensuring the integrity of the entire device structure and the smoothness of operation, which is conducive to fixing the steel plate 4.

[0021] Further such as Figure 5 and Figure 6 As shown, the support frame 503 forms a sliding structure with the positioning plate 507 via the slider 504, and the inner diameter of the groove 508 matches the outer diameter of the slider 504. The inner wall of the groove 508 is fitted to the outer wall of the slider 504. With the support of the support frame 503, the inner wall of the groove 508 on the positioning plate 507 slides on the outer wall of the slider 504, realizing the flexible linear movement of the positioning plate 507. This facilitates precise adjustment of its position, meets the needs of different working conditions, improves the flexibility and positioning accuracy of equipment operation, and is beneficial for the movement of the auxiliary block 506.

[0022] Further such as Figure 5 and Figure 6 As shown, the fixed plate 502 forms an elastic structure with the positioning plate 507 via the spring 505, and the spring 505 is disposed between the fixed plate 502 and the positioning plate 507. With the support of the fixed plate 502, the spring 505 can undergo elastic deformation under the action of the positioning plate 507, providing the positioning plate 507 with the reset power, ensuring the stable operation of the equipment, and facilitating the fixing of the steel sheet 4.

[0023] Working principle: When installing steel sheets 4 of different thicknesses or styles, the steel sheet 4 can be moved to enter the positioning frame 3 through the positioning groove 6. During the insertion process, the steel sheet 4 presses against the locking block 506, causing the locking block 506 to move the positioning plate 507 upward. This causes the positioning plate 507 to compress the spring 505, resulting in elastic deformation. The sliding groove 508 on the positioning plate 507 slides on the slider 504 on the support frame 503, allowing the steel sheet 4 to enter the positioning frame 3 through the locking block 506. The spring 505 then returns to its original position, causing the positioning plate 507 to move the locking block 506 downward. This causes the bottom of the locking block 506 to press and fix the steel sheet 4, thus securing it. Finally, two bolts 501 are used to fix the steel sheet 4 to the positioning frame 3. Disassembly is required. When installing steel sheet 4, first remove the two bolts 501, then pull the upward locking block 506 to allow steel sheet 4 to slide out of the positioning groove 6, thus completing the disassembly of steel sheet 4. This allows for the installation of steel sheets 4 of different thicknesses or styles. When it is necessary to print thermal adhesive on the product, the product can be moved and placed on the carrier plate 203. Then, the positioning frame 3 can be moved, causing the positioning frame 3 to move the steel sheet 4 and the protrusion 205. This allows the protrusion 205 to engage with the groove 204 on the fixing frame 201, aligning the hollow part on the steel sheet 4 with the part on the product that needs to be printed. Then, thermal adhesive is squeezed into the steel sheet 4. The scraper 1 is picked up from the connecting frame 202 and used to quickly scrape the thermal adhesive onto the product surface, resulting in a uniform and fast coating thickness, thus completing the thermal adhesive printing on the product.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
