Description

Technical Field

[0001] The present invention relates to the technical field of graphite sheet grinding, in particular to a graphite sheet grinding device and a grinding method capable of rapidly dissipating heat. Background Art

[0002] Graphite sheet is a new type of thermal conductive and heat dissipating material. During the cutting or die-cutting process, its edges are prone to forming sharp edges. If unpolished annular graphite sheets are used directly, their sharp edges may scratch the precision components or surrounding materials in electronic equipment, affecting the normal operation of the equipment. In addition, if there are cracks or burrs on the edges of the graphite sheet, they may become stress concentration points, causing the graphite sheet to crack during subsequent use, affecting the overall structural strength and durability. Therefore, the graphite sheet usually needs to be ground.

[0003] In the prior art, when a graphite sheet is ground, there is no good heat dissipation structure, which can easily lead to local high temperature of the graphite sheet, causing thermal expansion of the graphite sheet, resulting in reduced dimensional accuracy or even structural deformation, affecting subsequent assembly or use. In addition, thermal stress concentration may cause microcracks inside the material, reducing mechanical strength, thereby causing edge chipping or breakage during the grinding process, reducing the yield rate, and increasing manufacturing costs. In view of this, the present invention is specially proposed. Summary of the invention

[0029] 3. For the graphite sheet grinding device capable of rapid heat dissipation, when the piston in the cylinder moves towards the end close to the cam, it can extract the coolant into the liquid tank through the second water pipe and make it enter the cylinder. When the piston moves towards the end away from the cam, the piston can push the coolant in the cylinder into the first water pipe, so that it enters the hollow rod and then sprays out from the nozzle for cooling operation, thereby preventing the graphite sheet from expanding due to heat, ensuring its dimensional accuracy, avoiding structural deformation that may affect subsequent assembly or use, and at the same time preventing microcracks from occurring inside the material, not reducing the mechanical strength, improving the yield rate, and effectively controlling the manufacturing cost.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Embodiment 1:

[0046] In this embodiment, when in use, first place the graphite sheet body 202 on the placement seat 2 and fix it. It should be noted that since the annular graphite sheet has excellent sealing performance and has both electrical conductivity and thermal conductivity functions, it is relatively common in the market. Therefore, in this application, it is mainly used for grinding the annular graphite sheet. After fixing the graphite sheet body 202, then place the fixing plate 303 on the sliding plate 3 and install and fix it. First, install the end with the grinding wheel 406 close to the graphite sheet body 202, and then the graphite sheet body 202 can be ground by the grinding wheel 406. Coarse grinding can be performed by the grinding wheel 406. When the coarse grinding is completed, change the installation method of the fixing plate 303, so as to grind the graphite sheet body 202 with the sandpaper 408 and perform fine grinding operations, thus completing the grinding operation of the graphite sheet body 202 completely. At the same time, a coolant is stored in the liquid tank 105. During the grinding operation, the suction assembly will work, so as to extract the coolant in the liquid tank 105, make it enter the hollow rod 708, and then spray out from the nozzle 709 to cool down the grinding position, so as to perform heat dissipation operations, avoid thermal expansion of the graphite sheet due to too high temperature, ensure the dimensional accuracy of the graphite sheet body 202, avoid deformation, facilitate subsequent assembly or use, and can avoid generating microcracks inside the material and improve the yield rate; specifically, a baffle 104 is arranged on the base 1 to fix the liquid tank 105.

[0047] Embodiment Two:

[0048] Refer to Figures 1 - 11, a graphite sheet grinding device capable of quickly dissipating heat, including a base 1, and further including a placement seat 2 fixedly arranged on the base 1, on which a graphite sheet body 202 is provided; a slide plate 3 is slidably arranged on the base 1, a fixing plate 303 is connected to the slide plate 3, a first U-shaped frame 4 and a second U-shaped frame 401 are respectively fixedly connected to the fixing plate 303, a first rotating frame 402 and a second rotating frame 403 are respectively rotatably connected in the first U-shaped frame 4 and the second U-shaped frame 401, a grinding wheel 406 and a mounting plate 407 are respectively arranged on the first rotating frame 402 and the second rotating frame 403, and a sandpaper 408 is arranged on the mounting plate 407; a liquid tank 105 and a hollow rod 708 are fixedly arranged on the base 1, and a nozzle 709 is arranged on the hollow rod 708; a suction assembly is further arranged on the base 1, when the suction assembly works, it can make the liquid in the liquid tank 105 enter the hollow rod 708 and spray out from the nozzle 709.

[0049] Two sliding grooves 101 are arranged on the base 1, a threaded rod 102 and a limiting rod 103 are respectively connected in the two sliding grooves 101, two bumps 301 are arranged at the bottom of the slide plate 3, one of the bumps 301 is threadedly connected to the threaded rod 102, and the other bump 301 is slidably connected to the limiting rod 103. Two limiting strips 302 are arranged on the slide plate 3, and the fixing plate 303 is arranged between the two limiting strips 302.

[0050] In this embodiment, by controlling the rotation of the threaded rod 102, the threaded rod 102 can be threadedly connected to the bump 301, thereby driving the bump 301 to move, and then making the slide plate 3 move. The arranged limiting rod 103 can limit the other bump 301, so that the slide plate 3 moves more stably. The arranged limiting strips 302 can make it more convenient to place the fixing plate 303.

[0051] A driving part 205 is arranged on the placement seat 2, the output end of the driving part 205 is connected with a fixing disk 206 through a rotating shaft, the fixing disk 206 is rotatably connected to the placement seat 2, a first lead screw 201 is arranged on the fixing disk 206, a rubber pad 203 is sleeved on the first lead screw 201, a first nut 204 is threadedly connected to the first lead screw 201, the top outer wall of the slide plate 3 is fixedly connected with a second lead screw 304, the fixing plate 303 is slidably connected to the second lead screw 304, and a second nut 305 is threadedly connected to the second lead screw 304.

[0052] When installing the graphite sheet body 202, first, the graphite sheet body 202 is sleeved on the first lead screw 201, then the rubber pad 203 is placed, and at the same time, the first nut 204 is tightened, so that the first nut 204 is in close contact with the rubber pad 203, thereby fixing the graphite sheet body 202 between the rubber pad and the fixed plate 206. Starting the driving part 205 can drive the graphite sheet body 202 to rotate, which is convenient for all-round grinding. The driving part 205 specifically uses a motor. When installing the fixing plate 303, the fixing plate 303 is inserted on the second lead screw 304, and then the second nut 305 is tightened to make the second nut 305 in close contact with the fixing plate 303, thereby fixing the fixing plate 303 and facilitating subsequent grinding operations.

[0053] A first motor 404 and a second motor 405 are respectively arranged in the first rotating frame 402 and the second rotating frame 403. The grinding wheel 406 is arranged at the output end of the first motor 404, and the mounting plate 407 is arranged at the output end of the second motor 405.

[0054] A frame plate 409 is provided on the mounting plate 407. A locking rod 411 is threadedly connected to the frame plate 409. One end of the locking rod 411 placed inside the frame plate 409 is connected to a clamping plate 410 for clamping the sandpaper 408.

[0055] When installing the sandpaper 408, the sandpaper 408 is directly wrapped around the mounting plate 407, and its two ends pass through the frame plate 409. At this time, the locking rod 411 is tightened to be threadedly connected to the frame plate 409, thereby driving the locking rod 411 to move and making the clamping plate 410 press the sandpaper 408 to realize the locking of the sandpaper 408.

[0056] A rotating shaft 5 is provided in both the first U-shaped frame 4 and the second U-shaped frame 401. The first rotating frame 402 and the second rotating frame 403 are both rotatably connected to the rotating shaft 5. A triangular groove 501 is provided on the rotating shaft 5. Fixed blocks 503 are fixedly connected to the outer walls of the first U-shaped frame 4 and the second U-shaped frame 401. An adjusting rod 504 is threadedly connected to the fixed block 503. A triangular block 505 that cooperates with the triangular groove 501 is connected to the adjusting rod 504. A handle 502 is provided on the rotating shaft 5.

[0057] In this embodiment, by starting the first motor 404, the grinding wheel 406 at its output end can be driven to rotate, thereby performing rough grinding on the graphite sheet body 202. By starting the second motor 405, the mounting plate 407 can be driven to rotate, so that the sandpaper 408 connected to the mounting plate 407 performs grinding on the graphite sheet body 202, improving the grinding effect.

[0058] Specifically, the grinding wheel 406 and the mounting plate 407 can also be adjusted to different inclination angles during use. When the rotating shaft 5 is rotated and the first rotating frame 402 or the second rotating frame 403 is adjusted to an appropriate angle, the adjusting rod 504 is rotated to be threadedly connected to the fixed block 503, thereby driving the adjusting rod 504 to move, and further driving the triangular block 505 to move, so that the triangular block 505 is inserted into the triangular groove 501 on the rotating shaft 5. At this time, the rotating shaft 5 can no longer rotate. Moreover, there are multiple triangular blocks 505 and multiple triangular grooves 501, which are arranged in a circumferential distribution on the outer wall of the rotating shaft 5 for one week, which can enhance the fixing effect on the rotating shaft 5, so that its inclined angle is fixed and convenient for use.

[0059] Embodiment Three:

[0060] Refer to Figures 1 - 11 , a graphite sheet grinding device capable of quickly dissipating heat, which is basically the same as Embodiment Two. Further, a support base 6 is fixedly connected to the base 1, a third motor 601 is provided on the support base 6, the output end of the third motor 601 is connected to a thin shaft 602, a turntable 603 is fixedly connected to the outer wall of the thin shaft 602, a card slot 604 is provided on the turntable 603, a tooth block 605 is connected in the card slot 604, an auxiliary gear 606 is provided on the threaded rod 102, and the auxiliary tooth block 605 is meshed with the auxiliary gear 606.

[0061] A first bevel gear 607 is further provided on the thin shaft 602, an auxiliary shaft 7 is provided on the base 1, a second bevel gear 701 meshed with the first bevel gear 607 is provided on the auxiliary shaft 7, a cam 702 is further provided at the top of the auxiliary shaft 7, the suction assembly includes a cylinder 703 connected to the base 1, a piston 704 is slidably connected in the cylinder 703, a connecting rod 705 is fixedly connected to the piston 704, a push plate 706 is provided at one end of the connecting rod 705 outside the cylinder 703, and the push plate 706 is matched with the cam 702.

[0062] In this embodiment, when the third motor 601 is started, the thin shaft 602 at its output end can be driven to rotate, thereby driving the turntable 603 and the tooth block 605 to rotate. The meshing of the tooth block 605 with the auxiliary gear 606 can drive the threaded rod 102 to rotate, thereby driving the slide plate 3 to move. During the specific grinding process, the number of tooth blocks 605 on the turntable 603 can be changed. If one tooth block 605 is selected, when the grinding wheel 406 contacts the graphite sheet body 202 and starts the grinding operation, the tooth block 605 can only drive the threaded rod 102 to rotate slowly, and at the same time, the slide plate 3 can be driven to move slowly, and further, the grinding wheel 406 can be driven to move slowly, better feeding towards the graphite sheet body 202, so as to realize the grinding operation. If the feeding operation is not required, the tooth block 605 can also be not used.

[0063] A first water pipe 707 and a second water pipe 710 are also provided on the cylinder 703. The first water pipe 707 is communicated with the hollow rod 708, and the second water pipe 710 is communicated with the liquid tank 105.

[0064] In this application, whether or not the tooth block 605 is selected for operation does not affect the third motor 601 driving the thin shaft 602 to rotate. Then, through the meshing of the first bevel gear 607 and the second bevel gear 701, the auxiliary shaft 7 is driven to rotate, and then the cam 702 is driven to rotate, thereby pushing the push plate 706 to move. Since a spring is provided between the piston 704 and the inner wall of the cylinder 703, the reciprocating movement of the piston 704 can be realized through the cam 702. Check valves are provided at the joints of the first water pipe 707, the second water pipe 710 and the cylinder 703. Therefore, when the piston 704 moves towards the end close to the cam 702, the coolant can be extracted from the liquid tank 105 through the second water pipe 710 and enter the cylinder 703. When the piston 704 moves towards the end away from the cam 702, the piston 704 can push the coolant in the cylinder 703 into the first water pipe 707, so that it enters the hollow rod 708 and then sprays out from the nozzle 709 for cooling operation, thereby preventing the graphite sheet from expanding due to heat, ensuring its dimensional accuracy, avoiding structural deformation from affecting subsequent assembly or use, and at the same time preventing microcracks from generating inside the material, not reducing the mechanical strength, improving the yield rate, and effectively controlling the manufacturing cost.
