Description

Technical Field

[0001] This invention relates to the field of graphene-aluminum high thermal conductivity composite materials technology, specifically to a thermally conductive graphene-aluminum film stacking device. Background Technology

[0002] The graphene-aluminum high thermal conductivity composite material is composed of sequentially stacked aluminum film and graphene film. It combines the good electrical conductivity and ductility of aluminum with the excellent thermal conductivity and mechanical properties of graphene, and has broad application prospects in the field of electronic heat dissipation.

[0003] The stacking process of graphene-aluminum high thermal conductivity composite material is as follows: first, lay a layer of graphene, then a layer of aluminum film, then another layer of graphene, and then apply alcohol to the graphene. After the application, lay another layer of aluminum film, then lay another layer of graphene and apply alcohol to the graphene. Alcohol is then applied alternately to the aluminum film and graphene in the above manner until the last layer of graphene is completed. This completes the stacking of graphene and aluminum film. The aluminum film and graphene layers are bonded together after being soaked in alcohol.

[0004] In existing technologies, graphene aluminum film stacking is generally done manually, which is inefficient and makes it difficult to control the quality of the stacked sheets. Summary of the Invention

[0058] The beneficial effects of this invention are reflected in:

Detailed Implementation

[0068] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0069] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0070] like Figures 1-6 As shown, this embodiment of the invention provides a thermally conductive graphene aluminum film stacking device, including a worktable 100, an aluminum film picking robot 200, a graphene picking robot 300, a pressing mechanism 400, and a coating liquid leveling mechanism 500.

[0071] The workbench 100 is equipped with an aluminum film placement station 110, a graphene placement station 120, and a stacking station 130.

[0072] The aluminum film picking robot 200 is used to pick up aluminum films one by one from the placement station 110 and stack them in the stacking station 130.

[0073] The graphene picking robot 300 is used to pick up graphene from the graphene placement station 120 one by one and stack it in the stacking station 130. The aluminum film and graphene stacked in the stacking station 130 are alternately stacked.

[0074] The clamping mechanism 400 is used to clamp the graphene portions stacked on the aluminum film.

[0075] The coating and leveling mechanism 500 is used to level and coat the unpressed areas of graphene with alcohol when the pressing mechanism 400 presses a portion of the graphene. When the coating and leveling mechanism is used, the entire graphene surface can be leveled and coated with alcohol by alternating the pressing mechanism 400 on the pressed areas of the graphene and the coating and leveling mechanism 500 on the areas of the graphene with the coating.

[0076] When using this equipment to stack graphene aluminum films, the graphene picking robot 300 first picks up graphene from the graphene placement station 120 and stacks it into the stacking station 130. Then, the aluminum film picking robot 200 picks up aluminum film from the aluminum film placement station 110 and stacks it into the stacking station 130, realizing the alternating stacking of graphene and aluminum film. The first and last layers are both graphene. When graphene is placed at the stacking station 130, the pressing mechanism 400 is first controlled to press the first end of the graphene stacked at the stacking station 130, and the coating leveling mechanism 500 is controlled to level the area of ​​the graphene not pressed by the pressing mechanism 400 towards the second end and coat it with alcohol. Then, the pressing mechanism 400 is controlled to press the second end of the graphene stacked at the stacking station 130, and the coating leveling mechanism 500 is controlled to level the area of ​​the graphene not pressed by the pressing mechanism 400 towards the first end and coat it with alcohol. By leveling the coating on both sides, the entire graphene surface can be leveled and coated with alcohol. By alternately stacking aluminum film and graphene in the above manner, graphene-aluminum film stacking can be achieved. Using the thermally conductive graphene-aluminum film stacking equipment of this invention, the stacking of graphene-aluminum films can be completed automatically, which improves the stacking efficiency and ensures the stacking quality compared to manual stacking.

[0077] It should be noted that, in this embodiment, the first layer of the product after stacking is graphene, the last layer is also graphene, and the graphene and aluminum film are alternately arranged in the middle layers.

[0078] In practice, aluminum foil is relatively thin and easily broken. In order to protect the aluminum foil, a PET protective film needs to be applied on it. When stacking the sheets, the PET protective film on the aluminum foil needs to be peeled off. Manually peeling the film is not only inefficient, but also easily damages the aluminum foil.

[0079] In this embodiment, when the aluminum film is stacked on the aluminum film placement station 110, the protective film on each layer of aluminum film is located on the bottom. By setting the film tearing mechanism 600, the protective film on the bottom of the aluminum film can be automatically torn off after the aluminum film picking robot 200 picks up the aluminum film.

[0080] In some embodiments, refer to Figure 2 The aluminum film picking robot 200 includes a vacuum suction cup 210 and a moving mechanism 220 for driving the vacuum suction cup 210 to lift, rotate horizontally, and move horizontally between the aluminum film placement station 110 and the stacking station 130.

[0081] It should be noted that the shape and size of the vacuum suction cup 210 in this embodiment are roughly the same as the aluminum film, so that the vacuum suction cup 210 can basically cover the aluminum film when it picks it up, avoiding tearing the aluminum film when it is peeled off.

[0082] Specifically, the moving mechanism 220 includes a first linear guide rail 221, a second linear guide rail 222, a first telescopic cylinder 223, and a first rotary table 224.

[0083] The first linear guide 221 extends from the aluminum film placement station 110 toward the graphene placement station 120. The first linear guide 221 is equipped with a first slide 2211 and a first linear drive mechanism 2212 for driving the first slide 2211 to move along the first linear guide 221. The first linear drive mechanism 2212 is preferably a lead screw motor.

[0084] The second linear guide 222 extends vertically and is fixed on the first slide 2211. The second linear guide 222 is equipped with the second slide 2221 and the second linear drive mechanism 2222 for driving the second slide 2221 to move along the second linear guide 222. The second linear drive mechanism 2222 is preferably a lead screw motor.

[0085] The first telescopic cylinder 223 is fixed on the second slide block 2221. The output end of the first telescopic cylinder 223 faces downward and is fixed with the first support 2231. The first telescopic cylinder 223 can preferably be a pneumatic telescopic cylinder.

[0086] The fixing component of the first rotary table 224 is fixed to the lower side of the first support 2231. The first rotary table 224 is preferably a pneumatic rotary table.

[0087] The vacuum suction cup 210 is fixed to the lower side of the rotating component of the first rotating stage 224.

[0088] Using the above structure, the lateral movement, lifting, and rotation control of the vacuum suction cup 210 can be achieved. It should be noted that the second linear drive mechanism 2222 mainly drives the vacuum suction cup 210 to lift and lower within a large range, while the first telescopic cylinder 223 mainly drives the vacuum suction cup 210 to lift and lower precisely within a small range. Through the cooperation of the two, the lifting height and accuracy requirements of the vacuum suction cup 210 can be met.

[0089] In some embodiments, refer to Figure 5 The film-tearing mechanism 600 includes a horizontal conveyor belt 610, a tape-adhesive assembly 620, and a tearing assembly 630.

[0090] The horizontal conveyor belt 610 is located between the aluminum film placement station 110 and the stacking station 130. The direction of rotation of the horizontal conveyor belt 610 is consistent with the direction of lateral movement of the vacuum chuck 210.

[0091] The tape application assembly 620 is used to apply tape 625 to the corner of the protective film on the underside of the aluminum film, with the tape 625 extending out of the aluminum film.

[0092] Specifically, the tape application assembly 620 includes a guide roller 621, a tape pulley 622, a cutter 623, and a cutter drive mechanism 624.

[0093] The guide roller 621 is parallel to the transverse direction of the horizontal conveyor belt 610 and is installed horizontally and rotatably behind the horizontal conveyor belt 610. The surface of the guide roller 621 is provided with an adhesive layer.

[0094] The belt pulley 622 is rotatably mounted below the horizontal conveyor belt 610. The belt 625 is led out from the belt pulley 622 and guided from the front of the guide roller 621 to the upper side of the guide roller 621. The back of the belt 625 is attached to the adhesive layer on the surface of the guide roller 621.

[0095] The cutter 623 is located behind the guide roller 621 and does not extend beyond the upper side of the guide roller 621.

[0096] The cutter drive mechanism 624 is used to drive the cutter 623 to cut the tape 625 that passes through the belt pulley 622. The cutter drive mechanism 624 is specifically a telescopic cylinder with its output end facing upward. The cutter 623 is fixed to the output end of the telescopic cylinder. The tape 625 above it can be cut by controlling the telescopic cylinder to extend and retract.

[0097] When applying tape 625 to the corners of the aluminum foil protective film, the tape 625 is pulled out from the tape pulley 622 with its front side facing up, and the back side of the tape 625 is adhered to the upper side of the guide roller 621. The vacuum suction cup 210 picks up the aluminum foil and drives the vacuum suction cup 210 to rotate, so that one corner of the aluminum foil is aligned with the tape 625 on the upper side of the guide roller 621. Then, the aluminum foil picked up by the vacuum suction cup 210 is pressed onto the tape 625 on the guide roller 621, so that the front side of the tape 625 is adhered to the corner of the aluminum foil protective film. On the lower side, the vacuum suction cup 210 is driven to move backward to pull the tape 625 pasted on the aluminum foil protective film backward. After the tape 625 is pulled out to a certain extent, the cutter 623 is driven to cut the tape 625, so that a section of the tape 625 pasted on the lower side of the aluminum foil protective film is retained to extend out of the aluminum foil. This realizes the automatic pasting of tape 625 on the corners of the lower side of the aluminum foil protective film. The cut tape 625 head is still stuck on the guide roller 621, ready for the next time to paste tape 625 on the corners of the aluminum foil protective film.

[0098] The tearing assembly 630 includes a mechanical clamp 631 and a mechanical clamp lifting drive mechanism 632. The mechanical clamp 631 is located near the front end of the horizontal conveyor belt 610 and is used to clamp the portion of the tape 625 that extends out of the aluminum film and is pasted under the protective film. The mechanical clamp 631 is preferably a pneumatic clamp. The mechanical clamp lifting drive mechanism 632 is used to drive the mechanical clamp 631 to lift and lower. The mechanical clamp lifting drive mechanism 632 is preferably a pneumatic telescopic cylinder.

[0099] When the film is peeled off, the vacuum suction cup 210 picks up the aluminum film and presses it onto the horizontal conveyor belt 610 to move forward. At the same time, the mechanical clamp lifting drive mechanism 632 drives the mechanical clamp 631 that clamps the tape 625 to move downward in sync, so as to peel off the protective film from the bottom of the aluminum film.

[0100] When peeling off the film, the vacuum suction cup 210 picks up the aluminum film, and the tape 625 is attached to the corner of the protective film on the underside of the aluminum film by the tape adhesive component 620. The tape 625 extends out of the aluminum film. Then, the vacuum suction cup 210 is controlled to press the picked-up aluminum film onto the horizontal conveyor belt 610. The extended part of the tape 625 attached to the front corner of the aluminum film is aligned with the top of the mechanical clamp 631. Then, the mechanical clamp lifting drive mechanism 632 drives the mechanical clamp 631 to rise and controls the mechanical clamp 631 to clamp the extended part of the tape 625. Then, the vacuum suction cup 210 that picks up the aluminum film is controlled to move forward on the horizontal conveyor belt 610. At the same time, the mechanical clamp lifting drive mechanism 632 is controlled to drive the mechanical clamp 631 that clamps the tape 625 to move downward in sync. The protective film can then be peeled off from the underside of the aluminum film by the tape 625. When the protective film is peeled off, the aluminum film is adsorbed on the bottom of the vacuum suction cup 210. At the same time, the direction of peeling off the film is from the edge of the aluminum film to avoid tearing the aluminum film. During the peeling process, the purpose of the vacuum suction cup 210 moving along the horizontal conveyor belt 610 is to maintain pressure on the vacuum suction cup 210 and prevent the aluminum film from being torn off the vacuum suction cup 210.

[0101] In some embodiments, refer to Figure 4 The clamping mechanism 400 includes a third linear guide rail 410, a second telescopic cylinder 420, and a pressure block 430.

[0102] The third linear guide 410 extends horizontally and is located on one side of the lamination station 130. The third linear guide 410 is provided with a third slide 411 and a third linear drive mechanism 412 for driving the third slide 411 to move along the third linear guide 410. The third linear drive mechanism 412 is preferably a lead screw motor. A second support 413 is fixed on the third slide 411.

[0103] The second telescopic cylinder 420 is located above the stacking station 130 and fixed on the second support 413. The output end of the second telescopic cylinder 420 faces downward. The second telescopic cylinder 420 is preferably a pneumatic telescopic cylinder.

[0104] The pressure block 430 is fixed to the output end of the second telescopic cylinder 420.

[0105] In this embodiment, when the graphene is coated and scraped, the graphene can be pressed by the pressing block 430 of the pressing mechanism 400. The pressing mechanism 400 can drive the pressing block 430 to move and rise and fall, so as to adjust the pressing position of the pressing block 430 on the graphene.

[0106] Furthermore, the workbench 100 is also equipped with a discharge station 140, which is located near the stacking station 130.

[0107] The third linear guide rail 410 extends from the stacking station 130 to the discharge station 140. The third linear drive mechanism 412 can drive the pressing block 430 to move between the stacking station 130 and the discharge station 140, so that after the aluminum film and graphene are stacked, they are pushed from the stacking station 130 to the discharge station 140 by the pressing block 430.

[0108] After the aluminum film and graphene are stacked, the pressing block 430 can be controlled to push the stacked product from the stacking station 130 to the unloading station 140, and finally the product is conveyed away by the belt at the unloading station 140, thus realizing the automatic unloading of the stacked product.

[0109] In some embodiments, refer to Figure 3 The equipment also includes a six-axis robotic arm 700, whose working area covers the aluminum film placement station 110 and the stacking station 130. The free end of the six-axis robotic arm 700 is fixed with a mounting bracket 710.

[0110] The graphene picking robot 300 includes a first picking frame 310 and a plurality of first vacuum suction heads 320 mounted on one side of the first picking frame 310. The first picking frame 310 is fixed on the mounting frame 710.

[0111] The coating leveling mechanism 500 includes a coating leveling frame 510 and a coating leveling head 520 mounted on the coating leveling frame 510. The coating leveling frame 510 is fixed on the mounting frame 710.

[0112] When the six-axis robotic arm 700 drives the first vacuum suction head 320 on the first pick-up frame 310 to pick up graphene downwards, the coating scraper head 520 on the coating scraper frame 510 faces to the side. When the six-axis robotic arm 700 drives the coating scraper head 520 on the coating scraper frame 510 to dip into alcohol or to coat and scrape the graphene at the stacking station 130, the first vacuum suction head 320 on the first pick-up frame 310 faces to the side.

[0113] In this embodiment, a six-axis robotic arm 700 can control a graphene picking robot 300 to pick up stacked graphene and a coating and leveling mechanism 500 to dip in alcohol and apply coating and leveling to the graphene at the stacking station 130.

[0114] When picking up stacked graphene, the first vacuum suction head 320 on the first pickup frame 310 is first driven downward by the six-axis robotic arm 700. At this time, the coating leveling frame 510 and the coating leveling head 520 are facing to the side to avoid obstructing the picking up of stacked graphene. Then, the graphene picking robot 300 is driven by the six-axis robotic arm 700 to pick up the graphene at the graphene placement station 120. Then, the six-axis robotic arm 700 is controlled to move the graphene picked up under the graphene picking robot 300 to the stacking station 130. After the graphene is moved into place, the graphene picking robot 300 is controlled to stack the graphene at the stacking station 130.

[0115] When coating and smoothing the graphene at the stacking station 130, the six-axis robotic arm 700 first drives the coating and smoothing head 520 on the coating and smoothing frame 510 downwards. At this time, the first pick-up frame 310 and the first vacuum suction head 320 are facing to the side to avoid obstructing the coating and smoothing process. Then, the six-axis robotic arm 700 drives the coating and smoothing head 520 to pick up alcohol from the alcohol pick-up point. Then, the six-axis robotic arm 700 moves the coating and smoothing head 520 to the stacking station 130 to coat and smooth the graphene.

[0116] In this embodiment, the graphene picking robot 300 and the coating and leveling mechanism 500 can be controlled by a six-axis robotic arm 700 to move and operate independently without affecting each other, which helps to simplify the structure and reduce equipment costs.

[0117] In some embodiments, a strip-shaped alcohol box 800 is provided in the working area of ​​the six-axis robotic arm 700. The strip-shaped alcohol box 800 stores alcohol, and the coating scraper head 520 can be moved to the strip-shaped alcohol box 800 to pick up the alcohol.

[0118] Continue to refer to Figure 3 The coating scraper head 520 includes a second rotating table 521, a third rotating table 522, a first scraper 523, and a second scraper 524.

[0119] The fixing component of the second rotary table 521 is fixed on the coating scraper 510. The second rotary table 521 is preferably a pneumatic rotary table.

[0120] The fixing component of the third rotary table 522 is fixed to the rotating component of the second rotary table 521, and the rotating component of the third rotary table 522 is coaxial with the rotating component of the second rotary table 521. The third rotary table 522 is preferably a pneumatic rotary table.

[0121] The first scraper 523 is mounted on the fixed part of the third rotary table 522 via the first bracket 5231.

[0122] The second scraper 524 is mounted on the rotating component of the third rotary table 522 via the second bracket 5241.

[0123] When dipping in alcohol, the third rotating platform 522 drives the second scraper 524 to rotate so that it forms a straight line with the first scraper 523, so that the first scraper 523 and the second scraper 524 can extend into the strip alcohol box 800 to dip in alcohol.

[0124] When the graphene at the stacking station 130 is coated and scraped, the third rotary table 522 drives the second scraper 524 to rotate to form a V-shape with the first scraper 523.

[0125] In this embodiment, the overall orientation of the first scraper 523 and the second scraper 524 can be adjusted by the second rotating table 521, and the included angle between the first scraper 523 and the second scraper 524 can be adjusted by the third rotating table 522.

[0126] When dipping in alcohol, the third rotating platform 522 drives the second scraper 524 to rotate until it forms a straight line with the first scraper 523. When the first scraper 523 and the second scraper 524 move into the strip-shaped alcohol container 800, the second rotating platform 521 drives the first scraper 523 and the second scraper 524 to be parallel to the length direction of the strip-shaped alcohol container 800. This facilitates the first scraper 523 and the second scraper 524 to reach into the strip-shaped alcohol container 800 to dip in alcohol. It should be noted that, because alcohol is volatile, when using it, spray an appropriate amount of alcohol into the strip-shaped alcohol container 800. Sponge heads can be installed at the bottom of the first scraper 523 and the second scraper 524 to pick up the alcohol sprayed into the strip-shaped alcohol container 800.

[0127] When the graphene at the stacking station 130 is coated and scraped, the third rotary table 522 drives the second scraper 524 to rotate to form a V-shape with the first scraper 523. The first scraper 523 and the second scraper 524, which are in a V-shape, push forward with their tips, which can better scrape the graphene.

[0128] Therefore, by adjusting the angle between the first scraper 523 and the second scraper 524, the requirements for alcohol dipping and graphene leveling can be better met.

[0129] In practice, the graphene layers stacked at the graphene placement station 120 are separated by release paper to keep them apart. A release paper collection station 150 is located near the graphene placement station 120. Removing one layer of graphene requires removing one layer of release paper, which is then placed in the release paper collection station 150. By using a release paper picking robot 900, the release paper can be automatically transferred from the graphene placement station 120 to the release paper collection station 150.

[0130] In some embodiments, refer to Figure 6The paper picking robot 900 includes a mounting base 910, a rotating arm 920, a swing mechanism 930, a first gear 940, a second gear 950, a toothed belt 960, and a second picking frame 970.

[0131] Mounting base 910 is fixed between graphene placement station 120 and release paper collection station 150.

[0132] One end of the rotating arm 920 is fixed with a rotating shaft, which is rotatably mounted on the mounting base 910. The other end of the rotating arm 920 can rotate between the graphene placement station 120 and the isolation paper collection station 150.

[0133] The swing mechanism 930 is connected to the rotating shaft and is used to drive the rotating arm 920 to swing. The swing mechanism 930 can use a motor as the power mechanism and a belt as the transmission mechanism to drive the rotating shaft to rotate.

[0134] The first gear 940 is rotatably mounted on the shaft and fixedly connected to the mounting base 910.

[0135] The second gear 950 is rotatably mounted on the other end of the rotating arm 920.

[0136] The toothed belt 960 is fitted between the first gear 940 and the second gear 950.

[0137] The second pickup frame 970 is fixed to the side end of the second gear 950, and a plurality of second vacuum suction heads 971 are provided on the lower side of the second pickup frame 970.

[0138] When it is necessary to pick up the release paper at the graphene placement station 120, the second pick-up frame 970 of the drive arm 920 is rotated to the graphene placement station 120. The second vacuum suction head 971 on the lower side of the second pick-up frame 970 is controlled to pick up the release paper. Then, the second pick-up frame 970 of the drive arm 920 is rotated to the release paper collection station 150. During the rotation of the drive arm 920, the first gear 940 is fixed and will drive the second gear 950 to rotate through the toothed belt 960. At the same time, the second gear 950 will revolve relative to the first gear 940. The rotation angle of the second gear 950 and the revolve angle of the second gear 950 are the same and the direction is opposite. In this way, the second vacuum suction head 971 on the second pick-up frame 970 can always be kept facing downwards during the rotation of the drive arm 920. After the second pick-up frame 970 rotates to the release paper collection station 150, the second vacuum suction head 971 is controlled to put down the release paper.
