Description

Technical Field

[0001] This utility model belongs to the field of thermally conductive silicone sheet processing technology, specifically a cutting and processing device for thermally conductive silicone sheets. Background Technology

[0002] Thermally conductive silicone pads are thermally conductive media materials synthesized through a special process using silicone as the base material and adding auxiliary materials such as metal oxides. The thermal conductivity typically ranges from 1.0W / mK to 6.0W / mK. They can efficiently transfer heat between heat-generating components (such as chips) and heat sinks, while also providing insulation, shock absorption, and sealing.

[0003] In the existing technology, CN221089120U describes a thermally conductive silicone sheet processing and cutting device, which includes a worktable and support plates fixedly connected to both sides of the top of the worktable. A cutting mechanism is provided between the top of the worktable and the opposite sides of the two support plates. The cutting mechanism is used to process and cut the thermally conductive silicone sheet. The cutting mechanism includes cutting shears disposed between the opposite sides of the two support plates. This utility model relates to the field of thermally conductive silicone sheet processing technology. This thermally conductive silicone sheet processing and cutting device, by setting a driving component, starts a driving motor. The output end of the driving motor drives a cam to rotate through a coupling and connecting shaft. This causes the cam to drive a connecting rod to drive a connecting column and a connecting block, thereby causing the connecting block to slide on one side of the support plate. During the sliding process, the cutting shears move up and down to cut the thermally conductive silicone sheet to a uniform size, thus achieving uniform cutting and improving cutting efficiency.

[0004] Existing thermal conductive silicone sheet processing and cutting equipment suffers from a problem during the cutting process: the area where the cutting structure contacts the thermal conductive silicone sheet undergoes partial deformation, which can easily cause a slight deflection of the silicone sheet's position during the cutting process, leading to errors in subsequent cutting positions. Therefore, this paper proposes a new thermal conductive silicone sheet processing and cutting equipment to address this issue. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4This utility model provides a cutting and processing device for thermally conductive silicone sheets, including a workbench 1; a transmission roller 9 is installed on the top of the workbench 1; a cutting frame 3 is fixedly connected to the top of the workbench 1; an electric push rod 4 is installed on the inner wall of the cutting frame 3; a metal block 5 is fixedly connected to the output end of the electric push rod 4; a cutting blade 6 is fixedly connected to the bottom of the metal block 5; a pressing body 11 is fixedly connected to the outer wall of the metal block 5; an abutment block 12 is slidably connected to the inner wall of the pressing body 11; a sliding rod 13 is fixedly connected to the top of the abutment block 12; the sliding rod 13 is slidably connected to the pressing body 11; a top plate 14 is fixedly connected to the top of the sliding rod 13; and the top plate 14 is fixedly connected to the top of the sliding rod 13. The plate 14 is fixedly connected to the return spring 15 via the pressing body 11. During operation, when cutting thermally conductive silicone sheets, the thermally conductive silicone sheet can be moved to the bottom of the cutting blade 6 first. Then, the electric push rod 4 can be activated to lower the metal block 5, causing the cutting blade 6 to abut against the top of the worktable 1, thereby achieving the function of cutting the thermally conductive silicone sheet. The abutting block 12 will first abut against the thermally conductive silicone sheet, while the slide rod 13 slides inside the pressing body 11, thereby causing the top plate 14 to drive the return spring 15 into a stretched state, thus enabling the abutting block 12 to abut against the thermally conductive silicone sheet.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, a support leg 2 is fixedly connected to the bottom of the worktable 1; a sliding rail 7 is fixedly connected to the top of the worktable 1; and a servo motor 8 is installed on the side of the sliding rail 7. During operation, the support leg 2 can support the worktable 1, and the servo motor 8 is installed on one side of the sliding rail 7, with the output end of the servo motor 8 passing through the sliding rail 7.

[0028] Furthermore, such as Figure 2 As shown, a double-threaded screw 10 is fixedly connected to the output end of the servo motor 8; a sliding block 21 is threadedly connected to the outer wall of the double-threaded screw 10. During operation, after the servo motor 8 is started, the double-threaded screw 10 can rotate on the inner wall of the sliding track 7, at which time the double-threaded screw 10 can cause the sliding block 21 threadedly connected to it to slide within a limited position on the inner wall of the sliding track 7.

[0029] Furthermore, such as Figure 2 As shown, a rotating support rod 22 is rotatably connected to one side of the sliding block 21; an auxiliary frame 18 is rotatably connected to one end of the rotating support rod 22. During operation, after the sliding block 21 slides, it can drive the rotating support rod 22 to rotate freely, thereby causing the rotating support rod 22 to rotate and abut against the auxiliary frame 18, so that the auxiliary frame 18 can abut against both sides of the thermally conductive silicone sheet for limiting after they come close together.

[0030] Furthermore, such as Figure 2As shown, an abutment roller 19 is rotatably connected to the inner wall of the auxiliary frame 18; an auxiliary block 20 is fixedly connected to the top of the auxiliary frame 18. During operation, the freely rotating abutment roller 19 can maintain the normal movement of the thermally conductive silicone sheet during the contact and limiting process.

[0031] Furthermore, such as Figure 2 As shown, a limiting block 16 is fixedly connected to the top of the sliding track 7; a limiting rod 17 is slidably connected to the inner surface of the limiting block 16; one end of the limiting rod 17 is set on the auxiliary block 20; the auxiliary block 20 is fixedly connected to the limiting rod 17. During operation, the limiting rod 17 can slide freely inside the limiting block 16, and after the limiting rod 17 is fixed to the auxiliary block 20, the auxiliary limiting frame 18 can move.

[0032] Working principle: When cutting thermally conductive silicone sheets, the thermally conductive silicone sheet can be moved to the bottom of the cutting blade 6 first. Then, the electric push rod 4 can be activated to lower the metal block 5, causing the cutting blade 6 to abut against the top of the worktable 1, thereby achieving the function of cutting the thermally conductive silicone sheet. The abutment block 12 will first abut against the thermally conductive silicone sheet, while the slide rod 13 slides inside the pressing body 11, thereby causing the top plate 14 to drive the return spring 15 into a stretched state, thus enabling the abutment block 12 to abut against the thermally conductive silicone sheet. The supporting feet 2 can support the worktable 1, and the servo motor 8 is installed on one side of the sliding rail 7, with the output end of the servo motor 8 passing through the sliding rail 7. After startup, the double-threaded screw 10 rotates on the inner wall of the sliding track 7. At this time, the double-threaded screw 10 can cause the sliding block 21, which is threaded to it, to slide in a limited position on the inner wall of the sliding track 7. After sliding, the sliding block 21 can drive the rotating support rod 22 to rotate freely. Then, after the rotating support rod 22 rotates, it abuts against the auxiliary frame 18, so that the auxiliary frame 18 can abut against both sides of the thermal conductive silicone sheet after they come close together and are limited. During the process of the thermal conductive silicone sheet abutting and limiting, the freely rotating abutting roller 19 can play the role of maintaining the normal movement of the thermal conductive silicone sheet. The limiting rod 17 can slide freely inside the limiting block 16. After the limiting rod 17 is fixed with the auxiliary block 20, the auxiliary frame 18 can be moved to be limited.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
