Description

Technical Field

[0001] This invention relates to the field of radiator manufacturing technology, and more specifically to an automatic heat dissipation paste application device. Background Technology

[0002] During the production and use of aluminum alloy heat sinks, a layer of thermal paste needs to be applied to a designated location on the contact surface between the heat sink and the heat-generating element to fill the gap between them and improve the heat dissipation effect.

[0066] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0067] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0068] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0069] To address the problems of low automation, high labor intensity, and low production efficiency in the existing method of applying thermal paste, which is performed manually, this invention provides an automatic thermal paste application device.

[0070] like Figures 1 to 5 As shown, the automatic thermal paste application device includes a coating platform 1, a feeding mechanism 2, a coating mechanism 3, and a discharging mechanism 4. The feeding mechanism 2 is located on one side of the coating platform 1 and is used to transport the heatsink 5 from the previous process position to the coating platform 1 and position it at the coating process position. The coating mechanism 3 is movably located above the coating platform 1 and is used to apply thermal paste to the heatsink 5. The discharging mechanism 4 is located on one side of the coating platform 1 and is used to push the coated heatsink 5 away from the coating platform 1 and transport it to the next process position.

[0071] Applying the technical solution of this embodiment, during the coating process of the heat sink, firstly, the feeding mechanism 2 transports the heat sink 5 from the previous process position to the coating platform 1 located below the coating mechanism 3, and positions it at the coating process position on the coating platform 1. Then, the coating mechanism 3 applies thermal paste to the heat sink 5 positioned at the coating process position. Finally, the unloading mechanism 4 pushes the coated heat sink 5 away from the coating platform 1 and transports it to the next process position. This setup enables the heat sink 5 to undergo an automated, assembly-line coating operation on the coating device, thereby giving the automatic thermal paste coating device provided in this application the characteristics of high automation, low manual labor intensity, and high production efficiency.

[0072] like Figure 1 , Figure 2 and Figure 5As shown, the coating platform 1 is equipped with a first guide member 10 and a stop member 11. The first guide member 10 is parallel to the loading path of the heat sink 5, and the stop member 11 is perpendicular to the loading path of the heat sink 5. The stop member 11 cooperates with the first guide member 10 to form an L-shaped coating process position on the coating platform 1. After the heat sink 5 is conveyed onto the coating platform 1, it will move along the first guide member 10 to the coating process position. The stop member 11 not only blocks the heat sink 5 during the loading process, but also guides the heat sink 5 during the unloading process. That is to say, the heat sink 5 after coating will be pushed away from the coating platform 1 along the stop member 11.

[0073] Preferably, the coating platform 1 is also provided with a third guide member 12, which is arranged parallel to and spaced apart from the first guide member 10, forming a feeding channel for the heat sink 5 on the coating platform 1. To accommodate heat sinks 5 of different specifications, the third guide member 12 is arranged on the coating platform 1 with an adjustable distance from the first guide member 10. For example, a waist-shaped hole design as shown in the figure can be used, or an existing servo drive mechanism can be used to achieve precise control of the distance. Of course, a gap must be provided between the third guide member 12 and the stop member 11 to form a feeding channel for the heat sink 5 to pass through.

[0074] In this embodiment, due to the L-shaped arrangement of the first guide member 10 and the stop member 11, the feeding mechanism 2 and the unloading mechanism 4 are arranged in an L-shape relative to the coating platform 1. Through the modular design of the feeding and unloading mechanisms, they can be flexibly arranged according to the site conditions, saving device space.

[0075] like Figures 1 to 4 As shown, the feeding mechanism 2 includes a conveying component 20 and a moving component 23. The conveying component 20 is disposed on one side of the coating platform 1 and can dock with the coating platform 1. It is used to convey the radiator 5 located in the previous process position to the edge of the coating platform 1. The moving component 23 can be disposed on the conveying component 20 or on the coating platform 1. It is used to push the radiator 5 located at the edge of the coating platform 1 along the first guide member 10 to the stop member 11. By maintaining the working state of the moving component 23, the radiator 5 can be positioned between the moving component 23 and the stop member 11.

[0076] like Figure 2 and Figure 5As shown, the conveying assembly 20 includes a conveying mechanism 21 and a lifting platform 22. The conveying mechanism 21 includes two parallel and spaced conveying tracks 213. Both ends of the radiator 5 can be mounted on the conveying tracks 213. The conveying tracks 213 can adopt a conventional belt, rail, or chain structure, as long as it is convenient to connect to the ends of the radiator 5. Thus, the radiator 5 can be suspended and supported for conveying via the conveying mechanism 21. The lifting platform 22 is located at one end of the conveying track 213, between the two conveying tracks 213. The lifting platform 22 can rise to be aligned with or slightly higher than the coating platform 1, achieving docking with it. The lifting platform 22 can also descend to the height to support the radiator 5. Therefore, when the radiator 5 is brought above the lifting platform 22 by the conveying mechanism 21, the lifting platform 22 rises, lifting the radiator 5 to the edge of the coating platform 1. Optionally, the lifting platform 22 is a double-acting lifting cylinder.

[0077] Accordingly, the moving component 23 includes a push plate 24 and a push plate drive unit 25. The push plate drive unit 25 is disposed on the coating platform 1 and located outside the first guide member 10. Optionally, the push plate drive unit 25 is a double-acting cylinder. The output end of the push plate drive unit 25 is drivenly connected to the push plate 24. The push plate 24 is used to push and position the radiator 5. Its extension direction is the same as the extension direction of the stop member 11. The push plate drive unit 25 drives the push plate 24 to reciprocate along the first guide member 10 above the conveying mechanism 21 and the coating platform 1. Thus, when the radiator 5 is lifted to the edge of the coating platform 1 by the lifting platform 22, the push plate drive unit 25 drives the push plate 24 to push the radiator 5 along the first guide member 10 to the stop member 11. The push plate drive unit 25 maintains a certain thrust, which can press the radiator 5 tightly between the push plate 24 and the stop member 11 to achieve the positioning of the radiator 5. After the radiator 5 is coated, the push plate drive unit 25 drives the push plate 24 back above the conveying mechanism 21, and reserves space for the radiator 5 to rise.

[0078] In this embodiment, during the journey of the heat sink 5 from the lifting platform 22 to the coating platform 1, a second guide member 26 can be provided on the conveying mechanism 21 to guide the heat sink 5. The second guide member 26 extends in the same direction as the first guide member 10 and can be connected. Figure 2 As shown, the second guide 26 extends to the coating platform 1 and is positioned above the first guide 10, thereby improving the guiding capability of the heat sink 5.

[0079] Preferably, in order for the aforementioned conveying mechanism 21 to be able to accommodate the conveying of radiators 5 of different specifications, the spacing of the conveying track 213 needs to be adjustable. Figure 5A feasible conveying mechanism 21 is shown, including a mounting plate 211, a fixed support 212, a conveying track 213, a side plate 214, a guide post 215, a movable support 216, and a support drive unit 217. The fixed support 212 is disposed on one side of the mounting plate 211, and a conveying track 213 is mounted on it. The side plate 214 is disposed on the other side of the mounting plate 211, opposite to the fixed support 212. The guide post 215 is disposed between the fixed support 212 and the side plate 214. The movable support 216 is slidably connected to the guide post 215, and another conveying track 213 is mounted on the movable support 216. The support drive unit 217 is disposed on the mounting plate 211, and its output end is drivenly connected to the movable support 216. In this way, by driving the movable support 216 to slide along the guide post 215 through the support drive unit 217, the distance between it and the fixed support 212 can be changed, thereby accommodating the conveying of radiators 5 of different specifications.

[0080] Optionally, the support base drive unit 217 is a servo screw module, and the movable support base 216 is provided with a screw seat connected to the screw in the middle. There are two guide columns 215 respectively arranged on both sides of the screw, which improves the movement stability of the movable support base 21 and ensures the position accuracy.

[0081] In one embodiment of this application (not shown), the conveying assembly 20 can also employ a conventional belt conveyor mechanism, with the belt conveyor face aligned with or slightly higher than the coating platform 1. Correspondingly, the moving assembly 23 requires an additional lifting mechanism. When the radiator 5 moves to the edge of the coating platform 1, the push plate 24 descends, pushing the radiator 5 along the first guide member 10 to the stop member 11. After coating is completed, the push plate 24 rises back to its initial position. In this configuration, since the belt can accommodate radiators of different specifications, only corresponding guide mechanisms need to be provided on both sides of the belt.

[0082] like Figure 3As shown, the coating mechanism 3 includes a steel mesh fixing frame 30, a first guide rail 31, a scraper part 32, a first drive part 33, and a steel mesh 301. The steel mesh 301 is disposed at the bottom of the steel mesh fixing frame 30 and located above the coating platform 1, specifically above the coating process position of the coating platform 1. The first guide rail 31 is disposed on the steel mesh fixing frame 30 and located above the steel mesh 301. The extension direction of the first guide rail 31 is the same as the extension direction of the first guide member 10. The scraper part 32 is slidably connected to the first guide rail 31, and the scraping end of the scraper part 32 abuts against the steel mesh 301. The first drive part 33 is disposed on the steel mesh fixing frame 30, and the output end of the first drive part 33 is drivenly connected to the scraper part 32 to drive the scraper part 32 to move relative to the steel mesh 301. Optionally, the first drive part 33 is a double-acting cylinder. Thus, during the application of thermal paste to the radiator, the radiator 5 is positioned below the steel mesh 301. The thermal paste is placed onto the steel mesh 12 via a feeding device or manually. The first drive unit 33 is activated, driving the scraping end of the scraping unit 32 to scrape from one end of the steel mesh 301 to the other end. The thermal paste passes through the holes in the steel mesh 301 and is applied to the radiator 5, completing the automatic application of the thermal paste. Since the movement direction of the scraping unit 32 is the same as the clamping direction of the radiator 5, the radiator 5 will not move during the application process, ensuring the stability of the application.

[0083] like Figure 3 As shown, the coating mechanism 3 also includes a mounting frame 34, a second guide rail 35, and a second drive unit 36. The second guide rail 35 is mounted on the mounting frame 34 and extends vertically. The steel mesh fixing frame 30 is slidably connected to the second guide rail 35. The second drive unit 36 ​​is located on the top of the mounting frame 34, and its output end is drivenly connected to the steel mesh fixing frame 30. Thus, by driving the steel mesh fixing frame 30 up and down via the second drive unit 36, it can be adapted to radiators 5 of different heights. Optionally, the second drive unit 36 ​​is a double-acting lifting cylinder, and there are two second guide rails 35 respectively located on both sides of the second drive unit 36, improving the smoothness of the vertical movement of the steel mesh fixing frame 30 and ensuring the positional accuracy of the coating mechanism 3 repeatedly descending to the coating position.

[0084] like Figure 3As shown, the coating mechanism 3 also includes a base plate 37, a third guide rail 38, and a third drive unit 39. The third guide rail 38 is horizontally mounted on the base plate 37, and its extension direction is perpendicular to the extension direction of the first guide member 10. The mounting bracket 34 is slidably connected to the third guide rail 38. The third drive unit 39 is mounted on the base plate 37, and its output end is driven to the mounting bracket 34. Thus, by driving the mounting bracket 34 to move left and right through the third drive unit 39, it can be adapted to heat sinks 5 of different widths. Optionally, the third drive unit 39 is a lead screw module, with the bottom of the mounting bracket 34 connected to the lead screw. Two third guide rails 38 are respectively mounted on both sides of the third drive unit 39, improving the stability of the horizontal movement of the mounting bracket 34 and ensuring the positional accuracy of the coating mechanism 3.

[0085] like Figure 3 As shown, the scraping section 32 includes a scraper cylinder plate 302, two scraper cylinders 303, and two scrapers 304. The scraper cylinder plate 302 is slidably connected to the first guide rail 31. The two scraper cylinders 303 are respectively disposed on both sides of the scraper cylinder plate 302, and the two scrapers 304 are respectively connected to the output ends of the two scraper cylinders 303. The end of the scraper 304 near the steel mesh 301 forms the scraping end. When applying thermal paste to the radiator 5, one scraper cylinder 303 is first extended, and the scraper 304 on it scrapes the thermal paste from one end of the steel mesh 301 to the other end of the steel mesh 301. Then, the scraper cylinder 303 is retracted, and the other scraper cylinder 303 is extended, and the scraper 304 on it scrapes the thermal paste from one end of the steel mesh 301 to the other end of the steel mesh 301. By applying the thermal paste twice, the consistency, smoothness, and uniformity of the coating are ensured. Both coating processes are automatically controlled, thereby improving the coating quality of the thermal paste and further enhancing the automation level of the thermal paste application process.

[0086] like Figures 1 to 4 As shown, the unloading mechanism 4 includes a pushing component 41 and a transfer component 42. The pushing component 41 can be set on the coating platform 1 or on the transfer component 42. It is used to push the coated radiator 5 along the stop member 11 onto the transfer component 42. The transfer component 42 is set on one side of the coating platform 1 and can dock with the coating platform 1. It is used to transport the coated radiator 5 on it to the next process position.

[0087] like Figure 2 and Figure 5As shown, the pushing assembly 41 includes a pusher plate 43 and a pusher plate driving unit 44. The pusher plate driving unit 44 is disposed on the coating platform 1, located outside the stop member 11. Optionally, the pusher plate driving unit 44 is a double-acting cylinder. The output end of the pusher plate driving unit 44 is drivenly connected to the pusher plate 43. The pusher plate 24 is used to push the heat sink 5, and its extension direction is the same as the extension direction of the first guide member 10. The pusher plate driving unit 44 drives the pusher plate 43 to reciprocate along the stop member 11 above the coating platform 1. In this way, after the heat sink 5 is coated, the pusher plate driving unit 44 drives the pusher plate 43 to push the heat sink 5 along the stop member 11 onto the transfer assembly 42. Then, the pusher plate driving unit 44 drives the pusher plate 43 back to the outside of the first guide member 10, ready for the next push.

[0088] like Figure 1 and Figure 2 As shown, the transfer assembly 43 includes a belt conveyor mechanism. One end of the belt conveyor mechanism is connected to the coating platform 1, and the belt conveyor surface is aligned with or slightly lower than the coating platform 1, which facilitates the pusher plate 43 to push the heat sink 5 onto the belt and then transport it to the next process position. Of course, the transfer assembly 43 can also use the above-mentioned conveying assembly 20, so that the loading mechanism 2 and the unloading mechanism 4 are basically the same, realizing a modular design.

[0089] It is readily understood that the automatic thermal paste application device provided in this application can also be equipped with a corresponding PLC, display, inductive switches, detection switches, and alarm devices. Through sensor detection and PLC control, it can achieve the positioning, automatic application, and release of the radiator 5 upon its entry into the workstation. Furthermore, the automatic thermal paste application device provided in this application optimizes the movement speed and path of each cylinder and lead screw module based on the mass and geometric shape of the radiator 5, in order to achieve rapid and stable positioning and application of the radiator 5.
