Abstract

The utility model relates to a heat-conducting silicone grease smearing device and system. The heat-conducting silicone grease smearing device comprises a bearing plate, a screen frame and a scraper. According to the heat-conducting silicone grease smearing device and system, due to the fact that the net opening part is matched with the heating film in shape, when the scraper presses the net opening piece, the net opening part abuts against the heating film, and the sheet-shaped assembly abuts against other parts of the bearing plate, namely the part without the bearing groove, heat-conducting silicone grease can only make contact with the heating film through the scraper, and after scraping of the scraper, the heat-conducting silicone grease can be smeared on the heating film. The thickness of the heat-conducting silicone grease on the heating film is equal to that of the net opening part, so that the heat-conducting silicone grease on the heating film can be uniformly smeared, the condition that the heat-conducting silicone grease is not completely smeared or excessively smeared due to the size is avoided, the smearing quality is improved, and the smearing efficiency is improved.

[0051] Refer to FIG. 1 , which shows a schematic structural diagram of a thermal grease coating device 100 and a heating film 210 in an embodiment of the present application. The thermal grease coating device 100 provided in an embodiment of the present application includes: a supporting plate 110 and a screen frame 120 .

[0052] In the above-mentioned thermal grease coating device 100, a supporting groove 111 is provided on one side of the supporting plate 110, and the supporting groove 111 is adapted to the heating film 210. The mesh frame 120 includes a frame body 121 and an open mesh sheet 122, the open mesh sheet 122 covers the through hole of the frame body 121, the open mesh sheet 122 is connected to the side of the frame body 121 away from the supporting plate 110, and the frame body 121 is rotatably connected to the supporting plate 110, so as to make the open mesh sheet 122 cover or open the supporting groove 111. The open mesh sheet 122 has an open mesh portion 123 and a sheet component 124 connected to each other, the open mesh portion 123 is a mesh structure, specifically, the open mesh portion is provided with a fine mesh, the open mesh portion 123 is adapted to the shape of the heating film 210, and the sheet component 124 is used to block the thermal grease 230 from passing through.

[0053] 1, 3 and 6, in actual use of the thermal grease coating device 100, the frame 121 is first rotated to expose the supporting groove 111, and the heating film 210 is placed in the supporting groove 111. Since the supporting groove 111 is adapted to the heating film 210, the heating film 210 will not move in the plane during the subsequent coating process, so that the coating effect of the thermal grease 230 is better and the thickness of the thermal grease 230 is more uniform. Then, the frame 121 is rotated to drive the mesh sheet 122 to cover the supporting groove 111, and the thermal grease 230 is placed on the side of the sheet component 124 away from the supporting groove 111. At this time, the thermal grease 230 is on the side of the mesh sheet 122 close to the frame 121 to prevent the thermal grease 230 from contacting the heating film 210 when not coating. Then, the scraper 220 is abutted against the side of the mesh sheet 122 away from the supporting groove 111, and The mesh portion 123 is pressed to abut against the heating film 210, and then the scraper 220 is scraped to make the thermal grease 230 contact the heating film 210 through the fine mesh of the mesh portion 123. Since the mesh portion 123 and the heating film 210 are adapted in shape, when the scraper 220 presses the mesh sheet 122, the mesh portion 123 abuts against the heating film 210, and the sheet component 124 abuts against other parts of the support plate 110, that is, the part without the support groove 111. Therefore, the scraper 220 can make the thermal grease 230 only contact with the heating film 210, and after the scraper 220 scrapes, the thickness of the thermal grease 230 on the heating film 210 is the thickness of the mesh portion 123, thereby ensuring that the thickness of the thermal grease 230 on the heating film 210 is evenly applied, and the thermal grease 230 will not be incompletely applied or applied excessively due to size reasons, thereby improving the application quality and efficiency.

[0067] An embodiment of the present application provides a thermal grease coating system, which includes a scraper 220 and a thermal grease coating device 100. The scraper 220 abuts against the side of the open mesh 122 away from the support plate 110, and is used to evenly coat the thermal grease 230 placed on the side of the open mesh 122 away from the support plate 110.

[0068] During actual use of the above-mentioned thermal grease coating system, the supporting groove 111 is first exposed by rotating the frame 121, and the heating film 210 is placed in the supporting groove 111. Since the supporting groove 111 is adapted to the heating film 210, the heating film 210 will not produce a planar movement during the subsequent coating process, thereby making the coating effect of the thermal grease 230 better and the thickness of the thermal grease 230 more uniform. Then, the frame 121 is rotated to drive the mesh sheet 122 to cover the supporting groove 111, and the thermal grease 230 is placed on the side of the sheet component 124 away from the supporting groove 111. At this time, the thermal grease 230 is on the side of the mesh sheet 122 close to the frame 121 to prevent the thermal grease 230 from contacting the heating film 210 when not coating. Then, the scraper 220 is brought into contact with the side of the mesh sheet 122 away from the supporting groove 111, and the mesh sheet 122 is pressed to open. The portion 123 abuts against the heating film 210, and then the scraper 220 is scraped to make the thermal grease 230 contact the heating film 210 through the fine mesh of the mesh portion 123. Since the mesh portion 123 is adapted to the shape of the heating film 210, when the scraper 220 presses the mesh sheet 122, the mesh portion 123 abuts against the heating film 210, and the sheet component 124 abuts against other parts of the supporting plate 110, that is, the part without the supporting groove 111. Therefore, the scraper 220 can make the thermal grease 230 only contact with the heating film 210, and after the scraper 220 scrapes, the thickness of the thermal grease 230 on the heating film 210 is the thickness of the mesh portion 123, thereby ensuring that the thickness of the thermal grease 230 on the heating film 210 is evenly applied, and the thermal grease 230 will not be incompletely applied or over-applied due to size reasons, thereby improving the application quality and efficiency.

[0069] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
