Description

Technical Field

[0001] This utility model relates to the field of silicone sheet processing technology, specifically to a multi-layer composite structure high thermal conductivity silicone sheet processing fixture. Background Technology

[0002] As electronic devices evolve towards higher performance, higher power density, and miniaturization, the performance requirements for thermally conductive materials are becoming increasingly stringent. Single-material silicone sheets often struggle to simultaneously meet multiple requirements, including high thermal conductivity, high insulation, good compressibility, and mechanical strength. Therefore, the industry has developed multi-layered composite high thermal conductivity silicone sheets, typically composed of layered materials with different functions through a specialized process.

[0003] However, in the existing manufacturing process of multi-layer composite silicone sheets, a vacuum adsorption fixture is required to firmly adsorb the entire silicone sheet onto a platform to fix each layer of material, thereby ensuring the structural integrity and cutting quality of the product. However, when the silicone sheet is unfolded and sent to the adsorption platform, there are often slight ripples and wrinkles on the surface. Vacuum adsorption will cause the wrinkles to solidify, which will reduce the cutting quality of the silicone sheet. In order to solve the above problems, the inventors propose a multi-layer composite high thermal conductivity silicone sheet processing fixture to solve the above problems. Utility Model Content

[0004] To address the issue of wrinkles caused by the curing process of multi-layer composite silicone sheets after they are adsorbed onto a platform using a vacuum adsorption fixture, this invention aims to provide a processing fixture for multi-layer composite silicone sheets with high thermal conductivity.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a multi-layer composite high thermal conductivity silicone sheet processing fixture, including a vacuum adsorption fixture, a vacuum pump is installed on one side of the vacuum adsorption fixture, a vacuum tube is fixedly provided on one side of the vacuum pump, the vacuum tube is fixedly inserted into the vacuum adsorption fixture, a placement plate is fixedly provided inside the vacuum adsorption fixture, and a through groove is opened in the placement plate. The vacuum adsorption fixture has frames that slide on both sides, and a U-shaped frame that slides within the frames. A positioning frame is fixed within the U-shaped frame, and a flattening roller is rotatably connected within the positioning frame. A fixing frame is fixed on one side of the vacuum adsorption fixture, and a motor is mounted on one side of the fixing frame. A rotating shaft is fixedly mounted on the output end of the motor, and a first bevel gear is fixedly fitted onto the outer surface of the rotating shaft. A threaded rod is rotatably inserted into the vacuum adsorption fixture, and a second bevel gear is fixedly mounted at one end of the threaded rod. The first and second bevel gears mesh. A threaded block is fixed on one side of the frame, and the threaded block is threaded onto the outer surface of the threaded rod. A vacuum groove is formed inside the vacuum adsorption fixture, and a placement plate is fixedly mounted within the vacuum groove. The vacuum tube is connected to the vacuum... The slots are interconnected. First, place the entire multi-layer composite high thermal conductivity silicone sheet on the top surface of the vacuum adsorption fixture, positioning it on the top surface of the placement plate. Then, rotate the screw to move the movable block and the U-shaped frame. This allows the height of the flattening roller to be adjusted according to the different heights of the silicone sheet. Manually slide the baffle to make the slider slide on the outer surface of the slide rod, allowing the baffle to slide on the top surface of the vacuum adsorption fixture and the placement plate. This allows the baffle to be adjusted according to the different lengths of the silicone sheet. Then, insert the bolt thread into the baffle and into the slider, so that the bottom end of the bolt abuts against the outer surface of the slide rod. This allows the baffle to block the top of the slot, preventing excess air leakage during vacuum adsorption and increasing the adsorption force in the area where the silicone sheet needs to be fixed. Then the motor is turned on, which drives the rotating shaft to rotate and drives the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, causing the threaded rod to rotate, which in turn causes the threaded block to move the frame, so that the flattening roller moves to the top surface of the silicone sheet. At the same time, the worker manually holds down one end of the silicone sheet located below the flattening roller, and the flattening roller rolls on the top surface of the silicone sheet, which can flatten the flattening roller. After flattening, the vacuum pump is turned on, which causes the vacuum tube to extract the air in the vacuum tank and causes the through groove in the placement plate to adsorb and cure the silicone sheet.

[0006] Preferably, movable blocks are fixed on both sides of the U-shaped frame, the movable blocks are slidably disposed within the frame, a lead screw is rotatably inserted into the frame, and the movable blocks are threaded onto the outer surface of the lead screw.

[0007] Preferably, the top surface of the vacuum adsorption fixture is slidably provided with a baffle, the baffle is slidably attached to the top surface of the placement plate, the bottom surface of the baffle is fixedly provided with a slider, the vacuum adsorption fixture is provided with a sliding groove, a sliding rod is fixedly provided in the sliding groove, the slider is slidably sleeved on the outer surface of the sliding rod, a bolt is threadedly inserted into the baffle, and the bolt is movably inserted into the slider, the bottom end of the bolt is attached to the outer surface of the sliding rod, the baffle is provided with a threaded groove, and the bolt is threadedly inserted into the threaded groove.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The flattening roller moves on the top surface of the silicone sheet, while the worker manually holds one end of the silicone sheet located below the flattening roller. At the same time, the flattening roller rolls on the top surface of the silicone sheet, which can flatten the sheet. After flattening, the vacuum pump is turned on, and the through groove in the placement plate adsorbs and solidifies the silicone sheet, thus preventing wrinkles from forming on the vacuum-adsorbed silicone sheet and improving the cutting quality of the silicone sheet. 2. By sliding the baffle on the top surface of the vacuum adsorption fixture and the placement plate, the baffle can be adjusted according to the different lengths of the silicone sheet. Then the baffle can cover the top of the through groove, so that the excess through groove will not leak air during vacuum adsorption, thereby improving the adsorption force of the area where the silicone sheet needs to be fixed.

[0012] 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.

[0013] Example: Figure 1-5 As shown, this utility model provides a multi-layer composite structure high thermal conductivity silicone sheet processing fixture, including a vacuum adsorption fixture 1. A vacuum pump 11 is installed on one side of the vacuum adsorption fixture 1, and a vacuum tube 12 is fixedly provided on one side of the vacuum pump 11. The vacuum tube 12 is fixedly inserted into the vacuum adsorption fixture 1, and a placement plate 13 is fixedly provided inside the vacuum adsorption fixture 1. A through groove 131 is opened in the placement plate 13. The vacuum adsorption fixture 1 has frames 3 that slide on both sides. A U-shaped frame 33 slides within the frames 3, and a positioning frame 34 is fixed within the U-shaped frame 33. A flattening roller 35 is rotatably connected within the positioning frame 34. A fixing frame 2 is fixed on one side of the vacuum adsorption fixture 1, and a motor 21 is mounted on one side of the fixing frame 2. A rotating shaft 22 is fixed at the output end of the motor 21, and a first bevel gear 23 is fixedly sleeved on the outer surface of the rotating shaft 22. A threaded rod 24 is rotatably inserted into the vacuum adsorption fixture 1, and a second bevel gear 25 is fixed at one end of the threaded rod 24. The first bevel gear 23 meshes with the second bevel gear 25. A threaded block 26 is fixed on one side of the frames 3, and the threaded block 26 is threaded onto the outer surface of the threaded rod 24. A vacuum groove 101 is formed inside the vacuum adsorption fixture 1, and a placement plate 13 is fixedly placed inside the vacuum groove 101. A vacuum tube 12 is connected to the vacuum groove 101. By placing a multi-layered composite high thermal conductivity silicone sheet on the top surface of the vacuum adsorption fixture 1, positioning it on the top surface of the placement plate 13, and then turning on the motor 21, the rotating shaft 22 is driven to rotate, which in turn drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25, causing the threaded rod 24 to rotate, thereby causing the threaded block 26 to move the frame 3, and the flattening roller 35 to move on the top surface of the silicone sheet. At the same time, the worker manually presses one end of the silicone sheet located below the flattening roller 35, while the flattening roller 35 rolls on the top surface of the silicone sheet, thus flattening the flattening roller 35. After flattening, the vacuum pump 11 is turned on, causing the vacuum tube 12 to extract the air from the vacuum tank 101, and the through groove 131 in the placement plate 13 adsorbs and solidifies the silicone sheet, thus preventing wrinkles from appearing on the vacuum adsorbed silicone sheet and improving the cutting quality of the silicone sheet.

[0014] Movable blocks 32 are fixed on both sides of the U-shaped frame 33. The movable blocks 32 are slidably disposed within the frame 3. A lead screw 31 is rotatably inserted into the frame 3. The movable blocks 32 are threaded onto the outer surface of the lead screw 31.

[0015] By adopting the above technical solution, by rotating the lead screw 31, the movable block 32 drives the U-shaped frame 33 to move, thereby adjusting the height of the flattening roller 35 according to the different heights of the silicone sheet.

[0016] A baffle 4 is slidably provided on the top surface of the vacuum adsorption fixture 1. The baffle 4 is slidably attached to the top surface of the placement plate 13. A slider 42 is fixedly provided on the bottom surface of the baffle 4. A sliding groove 102 is opened in the vacuum adsorption fixture 1. A sliding rod 43 is fixedly provided in the sliding groove 102. The slider 42 is slidably sleeved on the outer surface of the sliding rod 43. A bolt 41 is threadedly inserted in the baffle 4, and the bolt 41 is movably inserted in the slider 42. The bottom end of the bolt 41 is attached to the outer surface of the sliding rod 43. A threaded groove 401 is opened in the baffle 4, and the bolt 41 is threadedly inserted in the threaded groove 401.

[0017] By adopting the above technical solution, the slider 42 is slid on the outer surface of the slide rod 43 by manually sliding the baffle 4, thereby causing the baffle 4 to slide on the top surface of the vacuum adsorption fixture 1 and the placement plate 13. This allows the baffle 4 to be adjusted according to the different lengths of silicone sheets. Then, the bolt 41 is threaded into the baffle 4 and inserted into the slider 42, so that the bottom end of the bolt 41 abuts against the outer surface of the slide rod 43. This allows the baffle 4 to cover the top of the through groove 131, so that during vacuum adsorption, the excess through groove 131 will not leak air, thereby improving the adsorption force in the area where the silicone sheet needs to be fixed.

[0018] Working principle: First, place the entire multi-layer composite high thermal conductivity silicone sheet on the top surface of the vacuum adsorption fixture 1, so that it is located on the top surface of the placement plate 13. Then, rotate the screw 31, so that the movable block 32 drives the U-shaped frame 33 to move. This allows the height of the flattening roller 35 to be adjusted according to the different heights of the silicone sheet. Manually slide the baffle 4, so that the slider 42 slides on the outer surface of the slide rod 43, and the baffle 4 slides on the top surface of the vacuum adsorption fixture 1 and the placement plate 13. This allows the baffle 4 to be adjusted according to the silicone sheet of different lengths. Then, insert the bolt 41 into the baffle 4 and insert it into the slider 42, so that the bottom end of the bolt 41 abuts against the outer surface of the slide rod 43. This allows the baffle 4 to block the top of the through groove 131, so that during vacuum adsorption, the excess through groove 131 will not leak air, thus improving the adsorption force of the area where the silicone sheet needs to be fixed. Then, the motor 21 is turned on, which drives the rotating shaft 22 to rotate and drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25 to drive the threaded rod 24 to rotate, which causes the threaded block 26 to move the frame 3, so that the flattening roller 35 moves on the top surface of the silicone sheet. At the same time, the worker manually presses one end of the silicone sheet located below the flattening roller 35, and the flattening roller 35 rolls on the top surface of the silicone sheet, which can flatten the flattening roller 35. After flattening, the vacuum pump 11 is turned on, so that the vacuum tube 12 extracts the air in the vacuum tank 101 and the through groove 131 in the placement plate 13 adsorbs and cures the silicone sheet.
