Description

Technical Field

[0001] This invention relates to an automated production line for electronic-grade heat sinks based on graphene, and more particularly to an automated production line for electronic-grade heat sinks based on graphene and its production process, belonging to the field of heat sink processing technology. Background Technology

[0002] Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms arranged in a hexagonal honeycomb lattice with sp2 hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties and has important application prospects in materials science, micro-nano fabrication, energy, biomedicine, and drug delivery. It is considered a revolutionary material for the future. Graphite heat sinks, also known as thermally conductive graphite sheets, are a new type of thermally conductive and heat-dissipating material with unique grain orientation, uniform heat conduction in two directions, and a layered structure that can adapt well to any surface. They can shield heat sources and components while improving the performance of consumer electronics.

[0003] The production of graphene heat sinks requires multiple processing steps. The processing involves laminating graphene with various transparent protective films and silicone films. This lamination process requires the use of composite rollers to continuously convey and compress the graphene film. However, commonly used composite rollers lack positioning capabilities, causing the graphene material and film to shift during the conveying process. This results in deviations in the lamination of the graphene material and film, affecting the processing quality of the graphene heat sink.

[0004] Therefore, improvements are urgently needed to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automated production line and manufacturing process for graphene-based electronic-grade heat sinks. The composite rollers are equipped with structures for conveying and positioning the graphene material and membrane, enabling the composite rollers to stably convey the graphene material and membrane, ensuring complete composite bonding and preventing displacement of the graphene material and membrane, thus preventing any impact on the processing quality of the graphene heat sink.

[0006] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0007] An automated production line for graphene-based electronic-grade heat sinks includes a support platform with multiple legs fixedly mounted on its bottom. Mounting blocks are mounted on both sides of the support platform. A first composite roller is mounted on the mounting blocks on the support platform. A first and second silicone protective film rolls are symmetrically mounted on one side of each first composite roller. Two first die-cutting blades connected via first fixing blocks are mounted on the other side of each first die-cutting blade. A second composite roller is mounted on the mounting blocks on one side of each first die-cutting blade. Two black single-sided adhesive rolls and a blue silicone protective film roll are symmetrically mounted on one side of each second composite roller. Two second die-cutting blades connected via second fixing blocks are mounted on the other side of each second composite roller. A third composite roller is mounted on the mounting block on one side of the first composite roller. A first transparent double-silicone release film roll and a second transparent double-silicone release film roll are symmetrically mounted on one side of the third composite roller. Two third die-cutting blades are mounted on the other side of the third composite roller via a third fixing block. A positioning and conveying mechanism is provided on the first composite roller, the second composite roller, and the third composite roller. The positioning and conveying mechanism includes a first support plate symmetrically mounted on the first composite roller, the second composite roller, and the third composite roller. A hydraulic rod is fixedly mounted on one side of the first support plate. A second support plate is fixedly mounted on the output end of the hydraulic rod.

[0014] Preferably, both the sliding groove inside the support frame and the support rod are configured as a convex shape.

[0015] Preferably, support frames are installed on both sides of the support frame, and limit plates are installed on the support frames.

[0016] Preferably, a production process for an automated production line of graphene-based electronic-grade heat sinks includes the following steps:

[0017] Step 1: The polyimide is fed into the carbonization furnace for carbonization. After carbonization, the material is conveyed to the graphitization furnace by an automatic conveying mechanism for graphitization. After graphitization, the resulting graphene material is discharged onto the conveyor platform.

[0018] Step 1: Insert the formed graphene heat sink into the first composite roller, and also insert the material on the first silicone protective film roll and the second silicone protective film roll into the first composite roller.

[0021] Step 4: The composite die-cut graphene heat sink is transported onto the conveyor table. The electric telescopic rod is activated to drive the slitting blade to descend and cut the graphene heat sink. The cut graphene heat sink falls into the collection box for collection.

[0022] This invention has at least the following beneficial effects:

This allows the first, second, and third composite rollers to stably convey the graphene materials and membranes, enabling them to be completely composited. This avoids the graphene materials and membranes from shifting, thus preventing any impact on the processing quality of the graphene heat sink. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-8 As shown in the figure, this embodiment provides an automated production line for electronic-grade heat sinks based on graphene and its production process embodiment.

[0036] An automated production line for graphene-based electronic-grade heat sinks includes a support platform 1. Multiple legs 2 are fixedly mounted on the bottom of the support platform 1. Mounting blocks 3 are mounted on both sides of the support platform 1. First composite rollers 4 are mounted on the mounting blocks 3 on the support platform 1. A first silicone protective film roll 5 and a second silicone protective film roll 6 are symmetrically mounted on one side of the first composite rollers 4. Two first die-cutting blades 8 are mounted and connected via first fixing blocks 7 on the other side of the first composite rollers 4. A second composite roller 9 is mounted on the mounting blocks 3 on one side of the first die-cutting blade 8. Two black single-sided adhesive rolls 10 and blue silicone protective film rolls 11 are symmetrically mounted on one side of the second composite rollers 9. Two second die-cutting blades 13 are mounted and connected via second fixing blocks 12 on the other side of the second composite rollers 9. Mounting blocks 13 are mounted on one side of the second die-cutting blades 13. On the mounting block 3, a third composite roller 14 is mounted. A first transparent double-silicone release film roll 15 and a second transparent double-silicone release film roll 16 are symmetrically mounted on one side of the third composite roller 14. On the other side of the third composite roller 14, two third die-cutting blades 18 are mounted by a third fixing block 17. A positioning conveying mechanism 19 is provided on the first composite roller 4, the second composite roller 9 and the third composite roller 14. The positioning conveying mechanism 19 includes a first support plate 20 symmetrically mounted on the first composite roller 4, the second composite roller 9 and the third composite roller 14. A hydraulic rod 21 is fixedly mounted on one side of the first support plate 20. A second support plate 22 is fixedly mounted on the output end of the hydraulic rod 21. Two fixing frames 23 are symmetrically fixedly mounted on one side of the second support plate 22. A positioning roller 25 is movably mounted on the fixing frame 23 by a bearing 24. By setting the positioning and conveying mechanism 19, structures for conveying and positioning graphene materials and membranes are provided on the first composite roller 4, the second composite roller 9, and the third composite roller 14, so that the first composite roller 4, the second composite roller 9, and the third composite roller 14 can stably convey graphene materials and membranes, so that the two can be completely composited, avoiding the graphene materials and membranes from shifting, and preventing the processing quality of graphene heat sinks from being affected.

[0037] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a conveyor 26 located on one side of the third composite roller 14 is installed on the top of the support platform 1. A fixed frame 27 is installed on the support platform 1. An electric telescopic rod 28 is fixedly installed inside the fixed frame 27. A slitting blade 29 is provided on the electric telescopic rod 28. A fixed plate 30 is fixedly installed on the output end of the electric telescopic rod 28. The fixed plate 30 and the slitting blade 29 are fixedly connected by multiple bolts 31. The first fixed block 7, the second fixed block 12 and the third fixed block 17 are all provided with grooves 32. Two springs 33 are symmetrically fixedly installed inside the grooves 32. A locking block 34 is fixedly installed at one end of the springs 33. The tops of the first die-cutting blade 8, the second die-cutting blade 13 and the third die-cutting blade 18 are all fixedly installed with slots 35 that engage with the locking block 34. One end of the locking block 34 is tapered. The graphene heat sink, after being processed by the first composite roller 4, the second composite roller 9, and the third composite roller 14, is conveyed to the conveyor table 26 via the setup of the conveyor table 26, the fixed frame 27, the electric telescopic rod 28, and the slitting blade 29. The electric telescopic rod 28 then lowers the slitting blade 29 to slit the graphene heat sink, dispersing it for easy collection. The fixing plate 30 and bolts 31 secure the slitting blade 29 to the electric telescopic rod 28, preventing it from falling off. With the arrangement of groove 32, spring 33, locking block 34 and slot 35, the connection between the first fixing block 7 and the first die-cutting blade 8, the second fixing block 12 and the second die-cutting blade 13, and the third fixing block 17 and the third die-cutting blade 18 is achieved by locking the locking block 34 and the slot 35 under the support of the spring 33. Since the locking block 34 has a certain degree of mobility under the action of the spring 33, and one end of the locking block 34 is also set as a cone, it is easy to disassemble the first die-cutting blade 8, the second die-cutting blade 13 and the third die-cutting blade 18, so that they can be replaced when damaged.

[0038] In this embodiment, as Figure 1 , Figure 7 and Figure 8As shown, a support frame 36 is fixedly installed on one side of the support platform 1, and a collection box 37 is installed on one side of the support frame 36. A support rod 38 connected to the support frame 36 is installed on the collection box 37. The support frame 36 and the support rod 38 are slidably connected. The sliding groove inside the support frame 36 and the support rod 38 are both set as convex structures. Support frames 39 are installed on both sides of the support frame 36, and limit plates 40 are installed on the support frames 39. With the arrangement of support frame 36, collection box 37 and support rod 38, a collection box 37 connected and supported by support frame 36 and support rod 38 is provided on one side of support platform 1, which facilitates the collection of the completed graphene heat sink. By setting support frame 36 and support rod 38 as sliding connection and convex structure, the sliding connection can reduce the friction between support frame 36 and support rod 38, making it easy to remove and transport collection box 37, while the convex structure plays a limiting role for support rod 38, preventing collection box 37 from falling off from the front. With the arrangement of support frame 39 and limiting plate 40, the two sides of support frame 36 can be blocked to prevent collection box 37 from sliding off the two sides of support frame 36.

[0039] In this embodiment, as Figures 1-4 As shown in the figure, the working process of the automated production line for graphene-based electronic-grade heat sinks and its production process provided in this embodiment is as follows:

[0040] Step 1: Insert the formed graphene heat sink into the first composite roller 4, and also insert the materials on the first silicone protective film roll 5 and the second silicone protective film roll 6 into the first composite roller 4. The composite is carried out under the rolling pressure of the first composite roller 4, and then die-cut by two first die-cutting blades 8.

[0041] Step 2: Insert the composite graphene heat sink into the second composite roller 9, and insert the materials on the black single-sided film roll 10 and the blue silicone protective film roll 11 into the second composite roller 9 to composite with the graphene heat sink. After composite, it is then die-cut by two second die-cutting blades 13.

[0042] Step 3: Next, the graphene heat sink after secondary composite is inserted into the third composite roller 14, and the materials on the first transparent double silicon release film roll 15 and the second transparent double silicon release film roll 16 are also inserted into the third composite roller 14 for final composite with them. Finally, it is die-cut by the third die-cutting blade 18.

[0043] Step 4: The composite die-cut graphene heat sink is transported onto the conveyor table 26. The electric telescopic rod 28 is activated to drive the slitting blade 29 to descend and slit the graphene heat sink. The slit graphene heat sink falls into the collection box 37 for collection.

[0044] In summary, according to the automated production line and process of graphene-based electronic heat sinks in this embodiment, the graphene heat sinks, after being processed by the first composite roller 4, the second composite roller 9, and the third composite roller 14, are conveyed to the conveyor 26 via the arrangement of the conveyor table 26, the fixing frame 27, the electric telescopic rod 28, and the slitting blade 29. The electric telescopic rod 28 is then activated to lower the slitting blade 29, which slits the graphene heat sink, dispersing it for easy collection. The fixing plate 30 and bolts 31 secure the slitting blade 29 to the electric telescopic rod 28, preventing it from falling off. The groove 32, spring 33, locking block 34, and slot 35 connect the first fixing block 7 to the first die-cutting blade 8, the second fixing block 12 to the second die-cutting blade 13, and the third fixing block 17 to the third die-cutting blade 18, all through the locking block 34 and slot 35 supported by the spring 33. The slot 35 engages for connection and fixation. Due to the action of the spring 33, the locking block 34 has a certain degree of mobility, and one end of the locking block 34 is also set as a cone, so it is easy to disassemble the first die-cutting blade 8, the second die-cutting blade 13, and the third die-cutting blade 18, which is convenient for replacement when damaged. With the setting of the support frame 36, the collection box 37 and the support rod 38, a collection box 37 connected and supported by the support frame 36 and the support rod 38 is set on one side of the support platform 1, which can facilitate the collection of the finished graphene heat sink. By setting the support frame 36 and the support rod 38 as a sliding connection and a convex structure, the sliding connection can reduce the friction between the support frame 36 and the support rod 38, making it easy to remove and transport the collection box 37. The convex structure plays a limiting role for the support rod 38, preventing the collection box 37 from falling off from the front. With the setting of the support frame 39 and the limiting plate 40, the two sides of the support frame 36 can be blocked to prevent the collection box 37 from sliding off the two sides of the support frame 36.
