Technical Field

[0001] This utility model relates to the field of thermal grease application, specifically a high-efficiency thermal grease application instrument. Background Technology

[0002] Thermal grease is applied between chips or other electronic devices and heat sinks to fill the microscopic gaps caused by the flatness or roughness of the devices, thereby establishing a good heat transfer path and quickly transferring the heat generated during the operation of the electronic devices to the heat sink, ensuring the normal operation of the electronic devices. It has a very common application in electronic devices. Common processes for applying thermal grease include automated dispensing, automated brushing, manual application with stencils / silk screens, and purely manual application.

[0003] In the production of electronic devices, heat dissipation management is crucial, and silicone grease, as a thermally conductive material, is widely used. However, existing coating technologies have significant shortcomings: automated equipment is costly, posing an economic challenge for large-scale production of ultra-large-sized or small-batch products; stencil / wire mesh technology requires customized fixtures, resulting in poor versatility and significant resource waste; while manual application is simple to operate, consistency is difficult to guarantee, and applying too much or too little grease will affect performance. In summary, existing silicone grease coating technologies cannot meet the needs of different sizes and thicknesses and have obvious limitations.

[0004] Therefore, a highly efficient thermal grease application instrument is proposed to solve the problem of not being able to meet the requirements of different sizes and thicknesses. Utility Model Content

[0024] 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.

[0025] Example 1:

[0026] Please see Figure 1-6This embodiment of a high-efficiency thermal grease application instrument includes a top plate 1 and two side plates 5, with the top plate 1 positioned between the two side plates 5. An adjustment unit 21 is provided on the top plate 1, connected to a scraper 2, which adjusts the position of the scraper 2 between the two side plates 5. The scraper 2 has a slope 23 near its bottom. A laterally movable sealing plate 4 is provided between the two side plates 5 corresponding to the slope 23, with a notch formed between the sealing plate 4 and the slope 23. A rubber tube 3 is inclinedly positioned on the top plate 1, with its outlet end 31 near the slope 23 and inclined accordingly. The rubber tube 3 is filled with material, and the movement of the side plates 5 causes the material to be discharged through the notch.

[0027] In application, the instrument is placed on the coating area of ​​the electronic device, and then the external feeding system is connected to the tube 3. With the continuous pressure provided by compressed air, the thermal grease in the tube 3 can be guided from the discharge end 31 to the inclined surface 23 on the scraper 2. When the thermal grease fills the connection between the inclined surface 23 and the sealing plate 4, the sealing plate 4 is pulled to separate the sealing plate 4 from the inclined surface 23 on the scraper 2. At this time, the thermal grease can fall onto the coating area of ​​the electronic device through the gap formed after the sealing plate 4 separates from the scraper 2. Then, the instrument can be pulled to move. As the instrument moves, the thermal grease can be applied to the coating area of ​​the electronic device with a fixed width and thickness through the scraper 2. Then, the pulling length is determined according to the specific size of the electronic device. The operation can be repeated multiple times to cover a larger area. At the same time, when applying the grease, the height of the scraper 2 between the two side plates 5 can be adjusted to apply thermal grease of different thicknesses.

[0028] Specifically, the inner side of the side plate 5 has a vertical groove 22 corresponding to the scraper 2, and the scraper 2 is slidably connected in the groove 22. The side plate 5 has a graduated groove corresponding to the groove 22. The bottom end of the adjusting unit 21 is connected to the top surface of the scraper 2, and drives the scraper 2 to move within the groove 22. The top plate 1 has a through hole through which the adjusting unit 21 passes, and a rubber ring is placed inside the through hole. The adjusting unit 21 is inserted into the rubber ring, and the bottom end of the adjusting unit 21 is connected to the top end of the scraper 2. When the coating thickness needs to be adjusted, the scraper 2 can be moved within the groove 22 by moving the adjustment unit 21. After the scraper 2 moves, the coating thickness can be determined based on the distance between the bottom surface of the scraper 2 and the coating area. After the scraper 2 is adjusted to the appropriate position, the scraper 2 can be positioned by the friction between the rubber ring and the adjustment unit 21 to prevent the scraper 2 from shifting during the coating process. At the same time, the position of the scraper 2 can be precisely controlled by the scale groove when the scraper 2 moves, thereby achieving precise control of the coating thickness.

[0029] Specifically, the external feeding system is an air compressor. Using an air compressor as an external feeding system is something that those skilled in the art can do, so it will not be described in detail. In application, the air compressor provides continuous air pressure into the hose 3 to deliver the thermal grease in the hose 3 to the coating area of ​​the electronic device.

[0030] Example 2:

[0031] The basic content is from Example 1, the difference being:

[0032] Please see Figure 2-5 In this embodiment, the discharge end 31 of the hose 3 is provided with a flat discharge nozzle 32 corresponding to the inclined surface 23. The inner side of the side plate 5 is provided with a sliding groove 33 corresponding to the flat discharge nozzle 32. The flat discharge nozzle 32 is slidably connected in the sliding groove 33. The top plate 1 is detachably connected to the hose 3 with an abutment plate 11. The top plate 1 and the abutment plate 11 form a groove 12 corresponding to the hose 3. The hose 3 abuts in the space enclosed by the two grooves 12 and moves linearly in the space. The scraper 2, the sealing plate 4 and the flat discharge nozzle 32 are of the same width.

[0033] During application, the external feeding system discharges the thermally conductive silicone grease from the tube 3 through the discharge end 31. The flat discharge nozzle 32 then delivers the thermally conductive silicone grease to the inclined surface 23 of the scraper 2. The flat discharge nozzle 32, which is the same width as the scraper 2 and the sealing plate 4, can evenly fill the inclined surface 23 of the scraper 2 with thermally conductive silicone grease, so as to avoid the coating gaps in the subsequent coating process and improve the coating quality.

[0034] Specifically, the top plate 1 and the abutment plate 11 are connected by bolts. The distance between the top plate 1 and the abutment plate 11 can be adjusted by rotating the bolts. After the distance between the top plate 1 and the abutment plate 11 is adjusted, the space enclosed by the two grooves 12 also changes. After the space becomes larger, the tube 3 can move within the space. In actual use, the position of the flat discharge nozzle 32 in the sliding groove 33 can be adjusted to ensure that there is enough thermally conductive silicone grease on the sealing plate 4 to support the coating work. At the same time, rotating the bolts can also separate the abutment plate 11 from the top plate 1 so that the tube 3 can be removed from the top plate 1.

[0035] Example 3:

[0036] The basic content is from Example 1, the difference being:

[0037] Please see Figure 3-6In this embodiment, a mounting groove 44 is vertically formed on the top surface of the side plate 5 near its inner side. A connecting block 43 is slidably connected in the mounting groove 44, and a connecting rod 45 is slidably inserted in the connecting block 43. The end of the connecting rod 45 is connected to the sealing plate 4. The sealing plate 4 abuts against the inclined surface 23. A baffle 46 is vertically formed on the top surface of the sealing plate 4. The end of the connecting rod 45 is connected to the baffle 46. The scraper 2, the sealing plate 4, and the baffle 46 form a storage space 47 on the inner side of the two side plates 5. The flat discharge nozzle 32 is located in the storage space 47. The sealing plate 4 is slidably connected between the two side plates 5, and the lower end of the sealing plate 4 faces the inclined surface 23. A guide groove 42 is horizontally formed on the inner side of the side plate 5. A protrusion 41 is provided on the sealing plate 4 corresponding to the guide groove 42. The protrusion 41 is slidably connected in the guide groove 42.

[0038] During application, before the coating process begins, the connecting rod 45 moves the baffle 46 and the sealing plate 4. At this time, the connecting rod 45 moves within the connecting block 43, and the sealing plate 4 separates from the inclined surface 23 on the scraper 2. The thermally conductive grease that is subsequently discharged can be applied to the coating area through the notch formed after the sealing plate 4 separates from the inclined surface 23 on the scraper 2. During the movement of the sealing plate 4, the protrusion 41 will also move within the guide groove 42. Through the cooperation of the protrusion 41 and the guide groove 42, the sealing plate 4 can be made more stable during movement. During the coating process, the thermally conductive grease will be stored in the storage space 47 after being introduced. Since the grease has a high viscosity, a sufficient amount needs to be accumulated to ensure continuous coating. The storage space 47 ensures that the instrument can perform continuous coating. After the coating process is completed, the connecting rod 45 is moved to make the sealing plate 4 abut against the inclined surface 23 on the scraper 2, which can also prevent excessive thermally conductive grease residue on the sealing plate 4.

[0039] Specifically, a stabilizing groove is laterally formed on the inner side of the side plate 5, and a stabilizing block is fixed on the baffle 46 corresponding to the stabilizing groove. The stabilizing block is slidably connected in the stabilizing groove. During the movement of the baffle 46, the stabilizing block will also move in the stabilizing groove. With the cooperation of the stabilizing block and the stabilizing groove, the baffle 46 can be made more stable when moving. The stabilizing block and the stabilizing groove, together with the protrusion 41 and the guide groove 42, further stabilize the movement of the baffle 46 and the sealing plate 4. The sealing plate 4, the protrusion 41, the baffle 46 and the stabilizing block are integrally formed. The connecting rod 45 is detachably connected to the baffle 46. The detachable connection method makes the instrument more functional.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
