Description

Technical Field

[0001] The utility model relates to the technical field of graphics card assembly production, in particular to a thermal paste application jig. Background Art

[0002] GPU, or graphics processing unit, is a processor specially designed to efficiently process large amounts of data in parallel. It is the core component of a graphics card and is responsible for performing complex mathematical and geometric calculations. It is particularly suitable for rendering images and performing complex computing tasks.

[0003] Modern GPUs need to perform a large number of operations per second, which will generate a lot of heat. In order to make the GPU run at the highest efficiency, a heat sink needs to be installed on the GPU for heat dissipation. Thermal paste is the heat-conducting medium between the heat sink and the GPU. Its function is to fill the gap between the heat sink and the GPU, increase the heat conduction efficiency, and thus make the heat dissipation effect of the graphics card better. Nowadays, thermal paste is usually applied to the GPU by pure manual method. The thermal paste needs to be squeezed onto the surface of the GPU first, and then the heat sink is used to squeeze the surface of the GPU to flatten the thermal paste and cover the GPU surface. However, the requirements for the amount of thermal paste squeezed onto the GPU surface are relatively strict. If the amount of thermal paste squeezed onto the GPU surface is too little, it is often the case that most areas of the GPU surface are not coated with thermal paste. If the amount of thermal paste squeezed onto the GPU surface is too much, not only will the thermal paste on the GPU surface be thicker and the thermal conductivity effect will be poor, but some of the thermal paste will also overflow onto the graphics card, and the product quality cannot be guaranteed. Nowadays, there are also tools such as scrapers to evenly spread the thermal paste on the surface of the GPU before installing the radiator. However, using a scraper to apply thermal paste not only requires a high level of operator skills, but also takes a long time to apply. Utility Model Content

[0028] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 1Schematic diagram of the structure of the thermal paste coating jig in the embodiment, the thermal paste coating jig in this embodiment includes a bearing component 1 and an coating component 2. The bearing component 1 includes a bearing plate 11 and a slot member 12, the bearing plate 11 has a coating working area, the slot member 12 is arranged on the bearing plate 11, and the notch of the slot member 12 faces the coating working area. The graphics card 100 extends into the notch of the slot member 12 for positioning and fixing, and the area to be coated of the graphics card 100 is located in the coating working area. The coating component 2 includes a cover member 21, a positioning member 22 and an coating member, the positioning member 22 is movably arranged on the bearing plate 11, one end of the cover member 21 is rotatably arranged on the positioning member 22, the movable end of the cover member 21 can be covered on the graphics card 100, the cover member 21 is provided with a coating hole 2111, and the coating member is movably arranged on the cover member 21. Adjust the positioning member 22 to the preset position of the carrier plate 11, cover the graphics card 100 with the cover member 21, the smearing hole 2111 corresponds to the area to be smeared of the graphics card 100, and the smearing member smears the thermal paste on the cover member 21 to the area to be smeared through the smearing hole 2111.

[0030] Refer to Figure 2 , Figure 2Schematic diagram of the structure of the carrier component in the embodiment. The thermal paste application jig in this embodiment is used to apply thermal paste on the GPU chip of the graphics card 100. In specific application, the card slot part 12 is provided with a slot that matches the gold finger of the graphics card 100. The operator first places the graphics card 100 on the carrier board 11, and then pushes the graphics card 100 to insert its gold finger into the slot of the card slot part 12, so that the graphics card 100 is positioned and fixed by the card slot part 12, ensuring that the graphics card 100 does not shake during the application of the thermal paste. At this time, the area to be applied on the graphics card 100 is located in the application work area. The area to be applied in this embodiment is the GPU surface on the graphics card 100. After the cover plate 21 is covered on the graphics card 100, the smearing hole 2111 on the cover plate 21 is directly opposite to the GPU on the graphics card 100. Specifically, since the positioning member 22 is movably arranged on the carrier plate 11, the position of the positioning member 22 is adjusted to drive the position of the cover plate 21 to change, so that after the cover plate 21 is covered on the graphics card 100, the smearing hole 2111 on the cover plate 21 can be directly opposite to the GPU on the graphics card 100. At this time, the thermal paste is squeezed on the surface of the cover plate 21, and the smearing member can push and scrape the thermal paste on the cover plate 21, and the thermal paste can be smeared on the GPU surface through the smearing hole 2111 when passing through the smearing hole 2111, which greatly improves the smearing efficiency. At the same time, the thickness of the cover plate 21 is the smearing thickness of the thermal paste, and the size of the smearing hole 2111 is the size of the smearing area of ​​the thermal paste, so as to ensure that the smearing amount of the thermal paste is constant, and improve the stability of production and product quality. Then, the cover plate 21 is lifted to remove the graphics card 100 after coating, and a new graphics card 100 is inserted to repeat the operation. This embodiment not only has a simple structure and low manufacturing cost, but also can realize continuous and rapid coating operation, improve coating efficiency, and ensure that the thermal conductive paste can be evenly coated on the GPU, thereby improving product quality. In this embodiment, the coating member is a coating scraper.

[0031] Refer to Figure 3-Figure 4 , Figure 3 It is a structural schematic diagram of the smearing component in the embodiment, Figure 4It is a structural schematic diagram of the coating cover in the embodiment. Preferably, the cover member 21 is also provided with a receiving groove 2121, which can accommodate thermal paste. The coating hole 2111 is provided at the bottom of the receiving groove 2121, and the coating member is movably arranged in the receiving groove 2121. In specific applications, a sufficient amount of thermal paste can be squeezed into the receiving groove 2121 in advance. When the cover plate 21 is covered on the graphics card 100, the thermal paste reserved in the receiving groove 2121 can be pushed and scraped through the smearing hole 2111 using the smearing piece, wherein part of the thermal paste is smeared onto the GPU through the smearing hole 2111, and the excess thermal paste is pushed and scraped to the other side of the receiving groove 2121 for next use. At the same time, the smearing piece also flattens the thermal paste in the smearing hole 2111, so that the thermal paste on the surface of the GPU is flush with the bottom of the receiving groove 2121, thereby ensuring that the amount of thermal paste applied each time is fixed. That is to say, when performing the smearing operation, there is no need to repeat the step of squeezing the thermal paste into the cover plate 21 many times. It is only necessary to squeeze a sufficient amount of thermal paste into the receiving groove 2121 in advance to maintain the continuous smearing operation for a longer period of time, thereby saving the time of squeezing the thermal paste and improving the efficiency.

[0032] Refer to Figure 5 , Figure 5 It is a structural schematic diagram of the groove portion in the embodiment. Preferably, the cover member 21 includes a smear cover 211 and a groove portion 212. The groove portion 212 is detachably installed in the middle of the smear cover 211. One end of the smear cover 211 is rotatably disposed on the positioning member 22. The accommodating groove 2121 is opened in the groove portion 212. In specific applications, the smear cover 211 is a transparent acrylic plate, and the groove portion 212 is an independent component, which is provided with a groove for accommodating the thermal paste, and the smearing hole 2111 is opened in the middle position of the bottom of the groove. It can be understood that the thermal paste is accommodated in the rest of the bottom of the groove and on the groove wall. When smearing, the smearing member can scrape an appropriate amount of thermal paste from the groove wall, and smear the thermal paste through the smearing hole 2111 and be pressed into the smearing hole 2111 by the smearing member and smeared on the GPU. The thermal paste smeared on the GPU is flush with the bottom of the groove. In this way, the thermal paste can be evenly applied to the GPU, and the excess thermal paste will also be scraped onto the groove wall by the smearing member for next use to avoid waste.

[0033] Re-reference Figure 3-Figure 5Preferably, a mounting opening 2112 is provided in the middle of the smear cover plate 211, and a plurality of disassembly holes 2113 are provided around the edge of the mounting opening 2112. A plurality of mounting holes 2122 are provided at positions of the groove portion 212 corresponding to the plurality of disassembly holes 2113. The groove portion 212 can be detachably mounted on the smear cover plate 211 through the cooperation of the disassembly holes 2113 and the mounting holes 2122. In specific applications, the mounting opening 2112 is a rounded square, and the groove portion 212 is adapted to the mounting opening 2112. The number of disassembly holes 2113 and the number of mounting holes 2122 are both eight, and two disassembly holes 2113 are provided on each side of the mounting opening 2112. Both the disassembly holes 2113 and the mounting holes 2122 are threaded holes. The fixing screws are passed through the mounting holes 2122 and fixed in the disassembly holes 2113 to realize the installation of the groove portion 212 on the smear cover plate 211. Similarly, the removal of the fixing screws can realize the removal of the groove portion 212. Since the size of the smear hole 2111 is adapted to the GPU, when different batches of graphics cards 100 need to be replaced for smearing, if the size and shape of the GPU change, the groove part 212 can be disassembled, and the smear hole 2111 can be replaced with the groove part 212 adapted thereto according to the size and shape of the GPU, so as to adapt to different types of graphics cards 100 and expand the scope of application. In addition, since the thermal paste is contained in the groove part 212 for a long time, the thermal paste is easy to solidify over time, and at this time, the old groove part 212 can be disassembled and replaced with a new groove part 212 for use. It should be particularly noted that the size of the smearing hole 2111 is slightly smaller than the size of the GPU, and the smearing hole 2111 has a certain thickness, that is, the groove portion 212 has a certain thickness. That is to say, when the smearing cover 211 is covered on the graphics card 100, the bottom of the groove portion 212 is in close contact with the graphics card 100, and the smearing piece is used to push and scrape the thermal paste in the groove portion 212 into the smearing hole 2111, that is, smear it on the surface of the GPU. At this time, the thickness of the thermal paste on the surface of the GPU is the thickness of the smearing hole 2111. In this way, it can be ensured that the amount of thermal paste applied each time is equal. The specific amount can be set according to the model and performance of the GPU, and the amount of thermal paste applied can be changed by changing the size and thickness of the smearing hole 2111. Furthermore, the smear hole 2111 includes a plurality of evenly arranged small holes, that is, the smear hole 2111 in the present embodiment is composed of 6x6 evenly arranged 36 small holes in total, and of course, it can also be set to other numbers in other embodiments. In this way, the thermal paste originally applied to the GPU is a whole piece, and through the setting of the small holes, the thermal paste is evenly divided into multiple small pieces. When squeezed by the radiator in the later stage, the thermal paste will spread more evenly.

[0034] Re-reference Figure 1-2Preferably, the cover plate 21 further comprises a rotating rod 213, one end of which is rotatably connected to the positioning assembly 2, and the other end of which is connected to the coating cover plate 211. In specific applications, the coating cover plate 211 and the rotating rod 213 are detachably connected. A plurality of threaded holes are provided on the other end of the rotating rod 213, and threaded holes are also provided at positions corresponding to the threaded holes of the coating cover plate 211. The detachment and connection of the coating cover plate 211 and the rotating rod 213 can be achieved by the cooperation between the fixing screws and the threaded holes. Since the thermal conductive paste is easy to stick to the coating cover plate 211 during work, it is not only easy to solidify on the coating cover plate 211 over time, but also the thermal conductive paste stuck on the coating cover plate 211 is extremely difficult to clean. During work, the thermal conductive paste on the coating cover plate 211 is easy to be contaminated on the graphics card 100, affecting the product quality. At this time, the coating cover plate 211 can be disassembled and replaced with a new coating cover plate 211 for use.

[0035] Refer to Figure 6 , Figure 6 2 is a schematic diagram of the structure of the positioning member in the embodiment. Preferably, the positioning member 22 includes a transverse positioning portion 221 and a longitudinal positioning portion 2222. The transverse positioning portion 221 is movably arranged on the carrier plate 11 along the transverse direction of the carrier plate 11, and the longitudinal positioning portion 2222 is movably arranged on the transverse positioning portion 221 along the longitudinal direction of the carrier plate 11. One end of the cover plate member 21 is rotatably arranged on the longitudinal positioning portion 2222. Since the graphics card 100 is placed on the carrier plate 11, the graphics card 100 is positioned by inserting the gold finger into the card slot member 12, and the cover plate member 21 is installed on the positioning member 22. In order to make the smearing hole 2111 on the cover plate member 21 accurately correspond to the position of the GPU, it is necessary to adjust the position of the positioning member 22, thereby adjusting the position of the cover plate member 21. It can be understood that the transverse positioning portion 221 is used to position the transverse position of the cover plate member 21, and the longitudinal positioning portion 222 is used to position the longitudinal position of the cover plate member 21. The transverse direction is the length direction of the carrier plate 11, and the longitudinal direction is the width direction of the carrier plate 11. By adjusting and positioning the cover member 21 through the transverse positioning portion 221 and the longitudinal positioning portion 222, when the cover member 21 is covered on the graphics card 100, the smearing hole 2111 can correspond to the position of the GPU. That is to say, before the smearing operation begins, it is only necessary to adjust the positions of the transverse positioning portion 221 and the longitudinal positioning portion 222 according to the specifications of the graphics card 100 to be smeared. During the operation, the graphics card 100 is inserted into the card slot 12, and the cover member 21 is covered to make the smearing hole 2111 face the GPU, so as to quickly complete the smearing position positioning, thereby realizing continuous smearing operations on the same batch of graphics cards 100 and improving production efficiency.

[0036] Re-reference Figure 6Preferably, the transverse positioning portion 221 is provided with a transverse first strip hole 2211, and the position of the supporting plate 11 corresponding to the first strip hole 2211 is provided with a first fixing hole 111. The transverse positioning portion 221 is movably arranged on the supporting plate 11 along the transverse direction of the supporting plate 11 through the cooperation of the first strip hole 2211 and the first fixing hole 111. In specific applications, the transverse positioning portion 221 is in the shape of a long strip and is installed on the carrier plate 11 along the length direction of the carrier plate 11. The first strip hole 2211 is also arranged along the length direction of the carrier plate 11. The fixing bolt passes through the first strip hole 2211 and is fixed in the first fixing hole 111. By adjusting the position of the fixing bolt passing through the first strip hole 2211, the transverse position of the transverse positioning portion 221 is adjusted, thereby adjusting the transverse position of the cover plate 21 to ensure that the position of the GPU is opposite to the smearing hole 2111. At the same time, when it is necessary to perform smearing operations on another batch of graphics cards 100, the position of the transverse positioning portion 221 can be adjusted according to the position of the GPU to adapt to different graphics cards 100, so as to broaden the adaptation range of this embodiment.

[0037] Re-reference Figure 6 Preferably, the longitudinal positioning part 222 is provided with a longitudinal second strip hole 2221, and the transverse positioning part 221 is provided with a second fixing hole at a position corresponding to the second strip hole 2221. The longitudinal positioning part 222 is movably arranged on the transverse positioning part 221 along the longitudinal direction of the carrier plate 11 through the cooperation of the second strip hole 2221 and the second fixing hole. In specific application, the longitudinal positioning part 222 includes two longitudinal positioning blocks arranged along the longitudinal direction of the carrier plate 11, and the longitudinal positioning blocks are provided with a longitudinal second strip hole 2221. The fixing bolt is fixed in the second fixing hole after passing through the second strip hole 2221. By adjusting the position of the fixing bolt passing through the second strip hole 2221, the longitudinal position of the longitudinal positioning part 222 is adjusted, thereby adjusting the longitudinal position of the cover plate 21, ensuring that the position of the GPU is directly opposite to the smearing hole 2111. At the same time, when another batch of graphics cards 100 need to be smeared, the position of the longitudinal positioning part 222 can be adjusted according to the position of the GPU to adapt to different graphics cards 100, so as to broaden the adaptation range of this embodiment. Specifically, the rotating rod 213 is rotatably connected to the two longitudinal positioning blocks respectively.

[0038] Preferably, the surface of the coating work area is covered with a protective film. In specific applications, the surface of the protective film is smooth. During the positioning process of placing the graphics card 100 on the carrier plate 11 and pushing the graphics card 100 into the card slot 12, the protective film can reduce the friction between the graphics card 100 and the carrier plate 11, and prevent the graphics card 100 from being worn. Moreover, after a long period of operation, the carrier plate 11 is easily stained with thermal paste, and the thermal paste is very difficult to clean after solidification. By setting the protective film, the thermal paste is prevented from directly adhering to the carrier plate 11, and adheres to the protective film. In this way, when the protective film is stained with thermal paste, the protective film can be directly replaced, saving the time of cleaning the carrier plate 11.

[0039] In summary, since the positioning member is movably arranged on the carrier plate, by adjusting the position of the positioning member, the position of the cover plate member is driven to change, so that after the cover plate member is covered on the graphics card, the smearing hole on the cover plate member can be directly opposite to the GPU on the graphics card. The thermal paste is squeezed into the groove part, and the smearing member can push and scrape the thermal paste in the groove part, and the thermal paste can be smeared on the GPU surface through the smearing hole when passing through the smearing hole, which greatly improves the smearing efficiency. At the same time, the thickness of the cover plate member is the smearing thickness of the thermal paste, and the size of the smearing hole is the size of the smearing area of ​​the thermal paste, so as to ensure that the amount of thermal paste applied is constant, improve the stability of production and product quality, and then lift the cover plate member to remove the graphics card after smearing, insert a new graphics card to repeat the operation, this embodiment is not only simple in structure and low in manufacturing cost, but also can realize continuous and rapid smearing operation, improve smearing efficiency, and can also ensure that the thermal paste can be evenly smeared on the GPU, improving product quality.

[0040] The above is only the implementation mode of the present application and is not intended to limit the present application.
