Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting silicone sheet production, in particular to a heat-conducting silicone sheet coating device. Background Art

[0002] Thermal conductive silicone sheet is a thermal conductive medium material that is synthesized through a special process with silicone as the base material and various auxiliary materials such as metal oxides. In the industry, it is also called thermal conductive silicone pad, thermal conductive silicone sheet, soft thermal conductive pad, thermal conductive silicone gasket, etc. It is specially produced for the design of transferring heat through gaps. It can fill the gaps and open up the heat channel between the heating part and the heat dissipation part, effectively improving the heat transfer efficiency. At the same time, it also plays the role of insulation, shock absorption, sealing, etc., which can meet the design requirements of miniaturization and ultra-thin equipment. It is highly manufacturable and usable, and has a wide range of applicable thicknesses. It is an excellent thermal conductive filling material.

[0003] For example, the utility model patent application number 202022633312.X discloses a device for producing thermally conductive silicone sheets, comprising a set of mounting plates; a first guide roller and multiple sets of coating rollers fixed between the mounting plates; the first guide roller disposed above the coating roller; a thermally conductive sheet passing sequentially between the multiple sets of coating rollers; a set of fixed plates and a second guide roller mounted on one side of the mounting plates; a PET sheet passing around the first guide roller, the coating roller, and the second guide roller, laminating to the thermally conductive sheet; a silicone strip mounted on the inner side of the fixed plate; the line along which the length of the silicone strip lies parallel to the line along which the length of the mounting plates lies. This utility model addresses the problem of uneven thickness of thermally conductive silicone sheets produced using coating equipment.

[0004] Although the device in the above patent solves the problem of uneven thickness of thermally conductive silicone sheets produced by coating equipment, it lacks the auxiliary heating function of the thermally conductive silicone during use. Since the thermally conductive silicone requires a certain shaping time during the calendering process, and since the thickness of the thermally conductive silicone after calendering is relatively thin, the thermally conductive silicone is easily cooled and dried during the calendering process and is no longer soft, which easily causes the thermally conductive silicone to be damaged during the calendering and coating process, thereby reducing the quality of the thermally conductive silicone after calendering and coating.

[0005] Therefore, it is necessary to provide a thermal conductive silicone sheet coating device to solve the above technical problems. Utility Model Content

Two blowing boxes 6 are fixedly connected between the opposite sides of the two limit plates 2. Several blowing nozzles 7 are provided on the top of the two blowing boxes 6. A fan 8 is fixedly installed on one side of one of the limit plates 2 through two connecting boxes 20. One side of one of the connecting boxes 20 is fixedly connected to a heating box 9 through a connecting pipe 10. An electric heating wire 11 is provided inside the heating box 9. The other side of the heating box 9 is fixedly connected to one of the blowing boxes 6. A leveling component, a collecting component and an adjusting component are provided on the table top 1.

[0032] Another blowing box 6 is connected to the connecting pipe 10 , the blowing end of the fan 8 is connected to the connecting box 20 close to the side of the heating box 9 , and the suction end of the fan 8 is connected to another connecting box 20 .

[0033] The leveling component includes a connecting plate 12 and a suction box 13. The connecting plate 12 is fixedly connected between the opposite sides of the two limit plates 2. The suction box 13 is fixedly connected between the two sides of the inner wall of the connecting frame 4. A scraper 14 is fixedly connected to one side of the suction box 13. The blade of the scraper 14 is level with the bottom of the outer surface of the calendering coating roller 2 5 closest to the cylinder 19, and can be abutted against the top of the thermal conductive silicone that has been transported after air cooling, to avoid slight bulges on the thermal conductive silicone after multiple calendering. The scraper 14 can be set to scrape the bulges, thereby improving the quality of the thermal conductive silicone after calendering and coating.

[0034] The collecting assembly includes a filter plate 15 and several suction heads 16. The filter plate 15 is fixedly connected to the inside of the connecting box 20 away from the side of the heating box 9. The several suction heads 16 are all arranged on one side of the suction box 13. The scraper 14 and the several suction heads 16 are all arranged on the same side of the suction box 13.

[0035] The adjustment component includes a bracket 18, which is fixedly connected to the top of the table 1. A cylinder 19 is fixedly installed on the bracket 18. The telescopic end of the cylinder 19 is fixedly connected to the top of the connecting frame 4. Through the setting of the adjustment component, the distance between the calendering coating roller 1 3 and the calendering coating roller 2 5 can be adjusted, so that thermal conductive silicone rubber of different thicknesses can be calendered, thereby improving the practicality of the device.

[0036] Working principle: During operation, the distance between the plurality of calendering coating rollers 1 3 and the plurality of calendering coating rollers 2 5 is adjusted according to the thickness of the thermal conductive silicone to be calendered and coated. That is, the cylinder 19 is started, and its telescopic end drives the connecting frame 4, the plurality of calendering coating rollers 2 5, the air suction box 13 and the scraper 14 to move synchronously. Then, the distance between the calendering coating roller 1 3 and the calendering coating roller 2 5 can be adjusted. At the same time, the distance between the scraper 14 and the connecting plate 12 can be adjusted. In this way, the calendering coating rollers 2 5, which decrease in sequence, cooperate with the calendering coating roller 1 3 to perform step-by-step calendering of the thermal conductive silicone during the calendering process.

[0037] In the process of calendering the thermally conductive silicone, the fan 8 and the electric heating wire 11 can be started. After the fan 8 is started, its suction end passes through the corresponding connecting box 20, hose 17 and suction box 13, so that several suction heads 16 generate suction, and its blowing end blows air into one of the blowing boxes 6 and the heating box 9 respectively under the action of the connecting box 20 and the connecting pipe 10 connected thereto. The wind blown into the heating box 9 can be heated by the electric heating wire 11 and then transported to the other blowing box 6. Then, hot air and natural wind can be blown out through several blowing nozzles 7 on the two blowing boxes 6, and the hot air blown out can be blown out by the blowing nozzles 7 on the two blowing boxes 6. The wind can heat the thermal conductive silicone during the calendering process to prevent it from drying out and losing its softness, and the natural wind can cool down the calendered thermal conductive silicone to make it dry. After it dries, it passes between the connecting plate 12 and the scraper, and the tube plate abuts against its top to scrape off the slightly raised parts of the dried thermal conductive silicone to ensure the thickness of the thermal conductive silicone after calendering. The scraped thermal conductive silicone residue can be sucked up by the suction head 16, and after passing through the suction box 13 and the hose 17, it enters the corresponding connecting box 20, and is intercepted by the filter plate 15 and collected in its connecting box 20, so that the workers can clean the residue later.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
