Description

Technical Field

[0001] This invention relates to the field of automated processing technology, specifically to a graphite sheet mounting and shaping device and its usage method. Background Technology

[0002] Graphite sheets are a novel thermally conductive and heat-dissipating material with a unique grain orientation that allows for uniform heat conduction in two directions. They offer high heat dissipation efficiency, small footprint, and light weight, eliminating "hot spot" areas and improving the performance of consumer electronics. They also boast high thermal conductivity, low thermal resistance, a wide temperature range, and are lightweight, flexible, and easy to process.

[0003] Existing graphite sheets are used to dissipate heat by being glued to devices. However, the surfaces of the graphite sheets are not all flat. During the graphite sheet bonding process, a mounting and shaping device is needed to shape the graphite sheets. In existing methods, the graphite sheets are placed directly on the processing table, which is not convenient for fixing and limiting their position. When using the shaping head to shape the sides of the graphite sheet, the force of the shaping head is directly transmitted to the graphite sheet, which can easily cause the graphite sheet to shift, thus affecting the effect of graphite sheet mounting and shaping. To address this, we propose a graphite sheet mounting and shaping device and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide a graphite sheet mounting and shaping device and a method for using it, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A graphite sheet mounting and shaping device includes a machine base and a shaping head. Support frames are connected to the bottom of the outer walls on both sides of the machine base, and a graphite sheet platform is installed on the top of the machine base. A limiting component is provided on the graphite sheet platform, including a suction cup, with the opening end of the suction cup facing the top of the graphite sheet platform. An air pump is connected to the bottom of the outer wall on the left side of the graphite sheet platform, and an air suction pipe is connected to the air suction port of the air pump. The other end of the air suction pipe is connected to the suction cup. Side limiting plates are slidably connected to both ends of the upper surface of the graphite sheet platform, and vertical limiting plates are slidably connected to both ends of the upper surface of the graphite sheet platform.

[0007] The top of the machine is also equipped with a gantry frame, which is equipped with a displacement mechanism. The displacement mechanism includes a folding plate, and the folding plate is connected to the upper part of the gantry frame. The bottom of the folding plate is connected to a moving beam, and the bottom wall of the moving beam is slidably connected to a U-shaped sliding frame. The right side wall of the U-shaped sliding frame is connected to a fixed plate, and the fixed plate is equipped with an electric telescopic rod. The telescopic end of the electric telescopic rod is equipped with an ear plate through a piston rod, and the ear plate is connected to the shaping head.

[0008] Preferably, a fixing box is installed at the top of the outer walls on both sides of the graphite sheet stage. A stepper motor is connected to the front end of each of the two fixing boxes. The output end of the stepper motor is connected to a rotating shaft. The other end of the rotating shaft is rotatably connected to the inner rear wall of the fixing box through a bearing. A rotating gear is fitted on the rotating shaft. A movable toothed plate is slidably connected laterally inside each of the two fixing boxes. The movable toothed plate is meshed with the rotating gear. The inner side of the movable toothed plate extends into the inner cavity of the machine tool. A connecting rod II is installed on the outer upper surface of the movable toothed plate. The other end of the connecting rod II is connected to the outer wall of the side limiting plate.

[0009] Preferably, a support base is connected to the bottom of the inner cavity of the graphite sheet stage. The two ends of the support base penetrate the front and rear side walls of the graphite sheet stage. A geared motor is installed on the front end of the support base. The output end of the geared motor is connected to a bidirectional lead screw. The other end of the bidirectional lead screw is rotatably connected to the rear inner wall of the support base through a bearing.

[0010] Preferably, the bidirectional lead screw is threaded with two sets of threaded blocks, a crossbar is installed on the upper part of the inner wall of the support base, and two sets of sliders are slidably connected on the crossbar. The bottom of the two sets of sliders is connected to the top of the two sets of threaded blocks respectively. Both sides of the top wall of the support base are provided with through grooves, and connectors are slidably connected in the two sets of through grooves. The bottom of the connector is connected to the top of the slider, and a connecting rod is installed on the top of the connector. The other end of the connecting rod is connected to the outer side of the vertical limiting plate.

[0011] Preferably, a transverse slide bar is connected to the back side wall of the folding plate, and a transverse slide groove matching the transverse slide bar is provided on the outer wall of the gantry frame. Two sets of identical connecting strips are symmetrically connected to the outer walls of both sides of the folding plate, and the ends of the connecting strips are connected to the support round bars at both ends of the displacement frame. The support round bars are movably arranged in the inner cavity of the gantry frame. Moving slide bars are connected to the top and bottom of the displacement frame, and moving slide grooves matching the moving slide bars are provided on the inner wall of the gantry frame. Tooth plates are connected to the top and bottom inner walls of the displacement frame, and a displacement gear meshes between the two sets of tooth plates. The gear assembly on the displacement gear is a half-angle gear, and a motor is connected to the rear end of the displacement gear. The motor is installed in the inner cavity of the gantry frame.

[0012] Preferably, the open end of the U-shaped sliding frame is directly opposite the bottom wall of the moving beam. The left outer wall of the U-shaped sliding frame is connected to a second motor. The output end of the second motor is connected to a drive shaft. The bottom end of the drive shaft is rotatably connected to the right inner wall of the U-shaped sliding frame through a bearing. A traveling gear is fitted on the drive shaft. The bottom wall of the moving beam has multiple sets of meshing grooves, and each set of meshing grooves is meshed with the traveling gear.

[0013] Preferably, the bottom wall of the movable beam is provided with two sets of T-slots, and the outer wall of the opening end of the U-shaped sliding frame is connected with two sets of T-blocks, and the two sets of T-blocks are slidably connected to the two sets of T-slots respectively.

[0014] Preferably, the bottom of the U-shaped sliding frame is equipped with guide rails distributed in a vertical direction, and the side of the guide rail near the shaping head is provided with a guide groove, and the guide groove is slidably connected to the ear plate connected to the shaping head.

[0015] S1: First, place the semi-finished product (a substrate, a gasket, and a graphite sheet arranged from bottom to top) on the upper surface of the graphite sheet carrier. The external controller controls the stepper motors on the front end of the two sets of fixed boxes on the limiting component to work synchronously. The operation of the stepper motor drives the rotating gear on the rotating shaft to rotate. Since the rotating gear is meshed with the moving toothed plate, the two sets of moving toothed plates drive the two sets of side limiting plates to move in opposite directions through the fixedly connected connecting rod 2 until the two sets of side limiting plates are respectively attached to the left and right ends of the semi-finished product, thus realizing the limitation of the left and right ends of the semi-finished product.

[0016] S2: Then, the controller controls the geared motor to work. The geared motor drives the bidirectional lead screw to rotate. After the two sets of threaded blocks connected to the bidirectional lead screw are limited by the sliding limit of the crossbar and the slider, the two sets of connecting parts can slide in the two sets of through slots. The connecting rod fixedly connected to the two sets of connecting parts drives the two sets of vertical limit plates to move in opposite directions until the two sets of vertical limit plates are respectively attached to the front and rear ends of the semi-finished product, realizing the limitation of the front and rear ends of the semi-finished product. The controller then starts the suction pump to work. The suction pump works to make the suction pipe suck air. After the suction cup generates suction force, it fixes the bottom end of the semi-finished product.

[0017] S3: The controller controls the electric telescopic rod on the displacement mechanism to work. The operation of the electric telescopic rod can drive the shaping head to move down, so that the shaping head moves down to the outside of one end of the shaping line. When the controller motor works, the displacement gear rotates, and the toothed plate that meshes with it drives the displacement frame to move, thereby driving the folding plate to move. The moving beam can then move laterally back and forth, which in turn allows the shaping head to move laterally. After the electric telescopic rod works again, the shaping head moves down until it contacts the semi-finished product and produces a slight squeeze.

[0018] S4: Finally, the controller controls the motor on the displacement mechanism to drive the walking gear on the drive shaft to rotate. Since the walking gear is connected to multiple sets of meshing grooves and the U-shaped slide frame is limited by the sliding of the T-block and the T-slot, the U-shaped slide frame can move back and forth on the bottom wall of the moving beam, which drives the shaping head to move back and forth. After the electric telescopic rod works again, the shaping head moves towards the shaping line until it is close to the side surface of the semi-finished product and generates a slight lateral squeeze, thus realizing the mounting and shaping of graphite sheets at different positions.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention utilizes the synchronous operation of two sets of stepper motors on the limiting component to drive the rotating gears on the shaft. Since the rotating gears mesh with the moving gear plates, the two sets of moving gear plates, via a fixedly connected connecting rod, can move the two sets of side limiting plates in opposite directions, thus limiting the left and right ends of the graphite sheet semi-finished product. The operation of the reduction motor drives the bidirectional lead screw to rotate. After the two sets of threaded blocks, threaded to the bidirectional lead screw, are limited by the sliding of the crossbar and the slider, the two sets of connecting parts can slide within the through groove. The fixedly connected connecting rod on the two sets of connecting parts then drives the two sets of vertical limiting plates to move in opposite directions, thus limiting the front and rear ends of the semi-finished product. After the suction pump starts working, the suction pipe generates suction, and the suction cup generates suction to fix the bottom of the semi-finished product. The position of the graphite sheet semi-finished product is fixed from multiple directions. The displacement mechanism drives the moving beam to move back and forth laterally. The operation of motor two can drive the walking gear on the drive shaft to rotate. Since the walking gear is connected to multiple sets of meshing grooves and the U-shaped slide frame is limited by the sliding of the T-shaped block and the T-shaped groove, the U-shaped slide frame can move back and forth on the bottom wall of the moving beam. The front-back and left-right positions of the shaping head can be adjusted, realizing the mounting and shaping of graphite sheets at different positions. The position of the graphite sheet is not easily offset during mounting and shaping, which improves the quality of graphite sheet mounting and shaping. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figure 1-10 The present invention provides a technical solution: a graphite sheet mounting and shaping device, including a machine base 1 and a shaping head 7. Support frames 2 are connected to the bottom ends of the outer walls on both sides of the machine base 1, and a graphite sheet carrier 3 is installed on the top of the machine base 1. A limiting component 4 is provided on the graphite sheet carrier 3. The limiting component 4 includes a suction cup 400, and the opening end of the suction cup 400 is directly facing the top of the graphite sheet carrier 3. An air suction pump 409 is connected to the bottom end of the outer wall on the left side of the graphite sheet carrier 3, and an air suction pipe 410 is connected to the air suction port of the air suction pump 409. The other end of the air suction pipe 410 is connected to the suction cup 400. Side limiting plates 408 are slidably connected to both ends of the upper surface of the graphite sheet carrier 3, and vertical limiting plates 404 are slidably connected to both ends of the upper surface of the graphite sheet carrier 3.

[0035] Before use, connect the electrical terminals of each electrical device to the external power supply and the electrical terminals of the controller (installed on the right outer wall of machine base 1) via wires. Machine base 1 is fixedly connected to the outer walls of two sets of support frames 2, which support machine base 1. Graphite sheet carrier 3 is fixedly installed on machine base 1. When mounting and shaping graphite sheets, place the semi-finished products (substrate, gasket, and graphite sheet arranged sequentially from bottom to top) on the upper surface of graphite sheet carrier 3. The substrate is a copper foil sheet, and the gasket is a stainless steel sheet. The two sets of side limiters 4... The lateral sliding of the limiting plate 408 causes the two sets of side limiting plates 408 to move in opposite directions until the two sets of side limiting plates 408 are respectively attached to the left and right ends of the semi-finished product. The sliding of the two sets of vertical limiting plates 404 in opposite directions until the two sets of vertical limiting plates 404 are respectively attached to the front and rear ends of the semi-finished product achieves the limitation of the semi-finished product around its perimeter. Finally, after the suction pump 409 works, the suction pipe 410 generates suction force. At this time, the suction cup 400 generates suction force and fixes the bottom end of the semi-finished product, thus fixing the position of the semi-finished product from multiple directions.

[0036] A gantry frame 5 is also installed on the top of the machine 1. A displacement mechanism 6 is provided on the gantry frame 5. The displacement mechanism 6 includes a folding plate 600, and the folding plate 600 is connected to the gantry frame 5. A moving beam 604 is connected to the bottom of the folding plate 600. A U-shaped sliding frame 605 is slidably connected to the bottom wall of the moving beam 604. A fixed plate 9 is connected to the right side wall of the U-shaped sliding frame 605. An electric telescopic rod 10 is provided on the fixed plate 9. An ear plate is installed at the telescopic end of the electric telescopic rod 10 through a piston rod. The ear plate is connected to the shaping head 7. The shaping head 7 is an existing structure. For example, CN219486662U discloses a graphite sheet mounting and shaping assembly, which also mentions a shaping head. This is an existing structure. The specific mounting and shaping principle will not be described here.

[0037] The bottom ends of the gantry frame 5 are welded and fixedly installed on the machine base 1 via support platforms. The two ends of the limiting rod 603 are fixedly connected to the upper inner wall of the gantry frame 5. The moving beam 604 has through holes for the limiting rod 603. The U-shaped sliding frame 605 is fixedly connected to the fixed plate 9. By extending and retracting the electric telescopic rod 10, the shaping head 7 can be moved down to the upper part of the outer side of the line to be shaped. By sliding the moving beam 604 and the limiting rod 603, the shaping head 7 can be moved laterally back and forth, and the electric telescopic rod 10 can be activated again. The shaping head 7 moves down until it contacts the semi-finished product and applies slight pressure. The U-shaped sliding frame 605 moves back and forth on the bottom wall of the moving beam 604, which drives the shaping head 7 to move back and forth. The front-back and left-right positions of the shaping head 7 can be adjusted. After the electric telescopic rod 10 works again, the shaping head 7 moves towards the shaping line until it is close to the side surface of the semi-finished product and applies slight lateral pressure. This realizes the mounting and shaping of graphite sheets at different positions. The position of the graphite sheet is not easily shifted during mounting and shaping, which improves the quality of graphite sheet mounting and shaping.

[0038] Among them, the top of the outer walls on both sides of the graphite sheet stage 3 is equipped with a fixing box 405. The front end of the two sets of fixing boxes 405 is connected to a stepper motor 406. The output end of the stepper motor 406 is connected to a rotating shaft. The other end of the rotating shaft is rotatably connected to the inner rear wall of the fixing box 405 through a bearing. A rotating gear 411 is sleeved on the rotating shaft. A movable toothed plate 412 is slidably connected in both sets of fixing boxes 405. The movable toothed plate 412 is meshed with the rotating gear 411. The inner side of the movable toothed plate 412 extends into the inner cavity of the machine tool 1. A connecting rod 2 407 is installed on the outer upper surface of the movable toothed plate 412. The other end of the connecting rod 2 407 is connected to the outer wall of the side limiting plate 408.

[0039] Two sets of fixed boxes 405 are fixedly connected to the outer walls of both sides of the machine base 1. Multiple sets of meshing grooves are opened on the movable tooth plate 412, and the meshing grooves are meshed with the rotating gear 411. Through holes are opened at both ends of the fixed box 405 and on both sides of the machine base 1, and the through holes are slidably connected to the movable tooth plate 412. After the stepper motors 406 on the two sets of fixed boxes 405 work synchronously, they can drive the rotating gear 411 on the rotating shaft to rotate. Since the rotating gear 411 is meshed with the multiple sets of meshing grooves opened on the movable tooth plate 412, after the movable tooth plate 412 is limited by the through holes, the movable tooth plate 412 can move laterally back and forth. The connecting rod 407 fixedly connected to the two sets of movable tooth plates 412 drives the two sets of side limiting plates 408 to move in opposite or opposite directions, so as to limit the left and right ends of the semi-finished product.

[0040] A support base 401 is connected to the bottom of the inner cavity of the graphite sheet stage 3. Both ends of the support base 401 penetrate the front and rear side walls of the graphite sheet stage 3. A geared motor 402 is installed on the front end of the support base 401. A bidirectional lead screw 413 is connected to the output end of the geared motor 402. The other end of the bidirectional lead screw 413 is rotatably connected to the rear inner wall of the support base 401 through a bearing. The operation of the geared motor 402 can drive the bidirectional lead screw 413 to rotate forward or in reverse.

[0041] Two sets of threaded blocks 414 are threadedly connected to the bidirectional lead screw 413. A crossbar 415 is installed on the upper inner wall of the support base 401. Two sets of sliders 416 are slidably connected to the crossbar 415. The bottom of the two sets of sliders 416 is connected to the top of the two sets of threaded blocks 414 respectively. Through slots 417 are opened on both sides of the top wall of the support base 401. Connectors 418 are slidably connected in the two sets of through slots 417. The bottom of the connector 418 is connected to the top of the slider 416. A connecting rod 403 is installed on the top of the connector 418, and the other end of the connecting rod 403 is connected to the outer side of the vertical limiting plate 404.

[0042] The two ends of the slider 416 are fixedly connected to the threaded block 414 and the connector 418 respectively. The top of the connector 418 is fixedly connected to the vertical limiting plate 404 through the connecting rod 403. The operation of the reduction motor 402 can drive the bidirectional lead screw 413 to rotate forward or reverse. After the two sets of threaded blocks 414, which are threaded to the bidirectional lead screw 413, are limited by the sliding of the slider 416 through the crossbar 415, the two sets of connectors 418, which are fixedly connected to the slider 416, can slide in opposite or opposite directions in the through groove 417. The connecting rod 403, which is fixedly connected to the two sets of connectors 418, drives the two sets of vertical limiting plates 404 to move in opposite or opposite directions, thereby achieving the limitation of the front and rear ends of the semi-finished product.

[0043] A transverse slide bar 601 is connected to the back side wall of the folding plate 600, and a transverse sliding groove matching the transverse slide bar 601 is provided on the outer wall of the gantry frame 5. Two sets of identical connecting strips 602 are symmetrically connected to the outer walls of both sides of the folding plate 600, and the ends of the connecting strips 602 are connected to the support round bars 6031 at both ends of the displacement frame 603. The support round bars 6031 are movably disposed in the inner cavity of the gantry frame 5. Moving slide bars 6032 are connected to the top and bottom of the displacement frame 603, and moving sliding grooves matching the moving slide bars 6032 are provided on the inner wall of the gantry frame 5. The inner wall is connected to toothed plates 6033, and two sets of toothed plates 6033 are meshed with displacement gears 6034. The gear assembly on the displacement gear 6034 is a half-angle gear, and the rear end of the displacement gear 6034 is connected to a motor 6035. The motor 6035 is installed in the inner cavity of the gantry frame 5. When the motor 6035 is working, the displacement gear 6034 rotates, and the toothed plates 6033 that mesh with it drive the displacement frame 603 to move, thereby causing the folding plate 600 to move. The moving beam 604 can then move laterally back and forth under the drive of the folding plate 600, which can drive the U-shaped sliding frame 605 and the shaping head 7 to move laterally back and forth.

[0044] The open end of the U-shaped sliding frame 605 is directly opposite the bottom wall of the moving beam 604. The left outer wall of the U-shaped sliding frame 605 is connected to the second motor 606. The output end of the second motor 606 is connected to the drive shaft 607. The bottom end of the drive shaft 607 is rotatably connected to the right inner wall of the U-shaped sliding frame 605 through a bearing. A traveling gear 608 is sleeved on the drive shaft 607. The bottom wall of the moving beam 604 has multiple sets of meshing grooves 609, and each set of meshing grooves 609 is meshed with the traveling gear 608.

[0045] The drive shaft 608 is fixedly connected to the walking gear 608. The operation of the motor 606 can drive the walking gear 608 fixedly connected to the drive shaft 607 to rotate forward or reverse. Since the walking gear 608 is engaged with the multiple sets of meshing grooves 609 opened on the bottom wall of the moving beam 604, and the U-shaped slide frame 605 is limited by the sliding of the T-shaped block 611 and the T-shaped groove 610, the U-shaped slide frame 605 can move laterally back and forth on the bottom wall of the moving beam 604, thereby adjusting the front and rear position of the shaping head 7. The front and rear and left and right positions of the shaping head 7 can be adjusted until the shaping head 7 is directly above the side plate of the semi-finished product that needs to be shaped. After the electric telescopic rod 10 is working, the bottom end of the shaping head 7 contacts the side of the semi-finished product, realizing the mounting and shaping of graphite sheets at different positions.

[0046] The bottom wall of the movable beam 604 is also provided with two sets of T-slots 610. The outer wall of the open end of the U-shaped sliding frame 605 is connected with two sets of T-blocks 611, and the two sets of T-blocks 611 are slidably connected to the two sets of T-slots 610 respectively. The two sets of T-blocks 611 are fixedly connected to the outer wall of the open end of the U-shaped sliding frame 605 respectively. After the T-blocks 611 and T-slots 610 are slidably limited, the U-shaped sliding frame 605 will not detach from the bottom wall of the movable beam 604 when it moves back and forth.

[0047] Example 2:

[0048] Reference Figure 7 This embodiment differs from the first embodiment in that: the bottom of the U-shaped sliding frame 605 is equipped with a vertically distributed guide rail 8, and the side of the guide rail 8 near the shaping head 7 is provided with a guide groove, and the guide groove is slidably connected to the ear plate connected to the shaping head 7; a sliding member is vertically slidably connected in the guide groove, and the sliding member is fixedly connected to the ear plate. After the sliding limit is provided by the guide groove in the guide rail 8, it is ensured that the shaping head 7 is in a vertical direction when moving vertically.

[0049] A graphite sheet mounting and shaping device and its usage method include the following steps.

[0050] S1: First, the electrical terminals of each electrical device are electrically connected to the external power supply and the electrical terminals of the controller (installed on the right outer wall of the machine base 1) through wires. The machine base 1 is fixedly connected to the outer wall of the two sets of support frames 2. The machine base 1 is supported by the two sets of support frames 2. The semi-finished product, the substrate, the gasket and the graphite sheet distributed from bottom to top, are placed on the upper surface of the graphite sheet carrier 3. The substrate is a copper foil sheet and the gasket is a stainless steel sheet. The external controller controls the stepper motors 406 on the front end of the two sets of fixed boxes 405 on the limiting component 4 to work synchronously. The operation of the stepper motor 406 drives the rotating gear 411 on the rotating shaft to rotate. Since the rotating gear 411 is meshed with the moving tooth plate 412, the two sets of moving tooth plates 412 drive the two sets of side limiting plates 408 to move in opposite directions through the fixedly connected connecting rod 407 until the two sets of side limiting plates 408 are respectively attached to the left and right ends of the semi-finished product, thus realizing the limitation of the left and right ends of the semi-finished product.

[0051] S2: Then, the controller controls the reduction motor 402 to work. The operation of the reduction motor 402 drives the bidirectional lead screw 413 to rotate. After the two sets of threaded blocks 414 connected to the bidirectional lead screw 413 are limited by the sliding limit of the cross bar 415 and the slider 416, the two sets of connecting parts 418 can slide in the two sets of through grooves 417. The connecting rod 403 fixedly connected to the two sets of connecting parts 418 drives the two sets of vertical limit plates 404 to move in opposite directions until the two sets of vertical limit plates 404 are respectively attached to the front and rear ends of the semi-finished product, realizing the limitation of the front and rear ends of the semi-finished product. The controller then starts the suction pump 409 to work. The suction pump 409 works to make the suction pipe 410 suck air. After the suction cup 400 generates suction force, it fixes the bottom end of the semi-finished product, fixing the position of the semi-finished product from multiple directions.

[0052] S3: The controller controls the electric telescopic rod 10 on the displacement mechanism 6 to work. The operation of the electric telescopic rod 10 can drive the shaping head 7 to move down, so that the shaping head 7 moves down to the upper part of the outer side of the line to be shaped. The controller motor 6035 works, the displacement gear 6034 rotates, and the toothed plate 6033 that meshes with it drives the displacement frame 603 to move, thereby driving the folding plate 600 to move. The moving beam 604 can then move laterally back and forth, which in turn allows the shaping head 7 to move laterally. After the electric telescopic rod 10 works again, the shaping head 7 moves down until it contacts the semi-finished product and produces a slight squeeze.

[0053] S4: Finally, the controller controls the motor 606 on the displacement mechanism 6 to drive the walking gear 608 on the drive shaft 607 to rotate. Since the walking gear 608 is engaged with multiple sets of meshing grooves 609 and the U-shaped slide frame 605 is limited by the sliding of the T-shaped block 611 and the T-shaped groove 610, the U-shaped slide frame 605 can move back and forth on the bottom wall of the moving beam 604, which drives the shaping head 7 to move back and forth. The front-back and left-right positions of the shaping head 7 can be adjusted. After the electric telescopic rod 10 works again, the shaping head 7 moves towards the shaping line until it is close to the side surface of the semi-finished product and generates a slight lateral squeeze, realizing the mounting and shaping of graphite sheets at different positions.

A graphite sheet mounting and shaping device and its method of use according to any one of claims 1-9, characterized in that: The method includes the following steps: S1: First, place the semi-finished product (the substrate, gasket and graphite sheet distributed from bottom to top) on the upper surface of the graphite sheet carrier (3). The external controller controls the stepper motor (406) on the front end of the two sets of fixed boxes (405) on the limiting component (4) to work synchronously. The operation of the stepper motor (406) drives the rotating gear (411) on the rotating shaft to rotate. Since the rotating gear (411) is meshed with the moving toothed plate (412), the two sets of moving toothed plates (412) drive the two sets of side limiting plates (408) to move in opposite directions through the fixedly connected connecting rod two (407) until the two sets of side limiting plates (408) are respectively attached to the left and right ends of the semi-finished product, thus realizing the limitation of the left and right ends of the semi-finished product. S2: Then, the controller controls the geared motor (402) to work. The work of the geared motor (402) drives the bidirectional lead screw (413) to rotate. After the two sets of threaded blocks (414) connected to the bidirectional lead screw (413) are limited by the sliding of the crossbar (415) and the slider (416), the two sets of connecting parts (418) can slide in the two sets of through slots (417). The connecting rod (403) fixedly connected to the two sets of connecting parts (418) drives the two sets of vertical limiting plates (404) to move in opposite directions until the two sets of vertical limiting plates (404) are respectively attached to the front and rear ends of the semi-finished product, thereby limiting the front and rear ends of the semi-finished product. The controller then starts the suction pump (409) to work. The suction pump (409) works to make the suction pipe (410) suck air. After the suction cup (400) generates suction force, it fixes the bottom end of the semi-finished product. S3: The controller controls the electric telescopic rod (10) on the displacement mechanism (6) to work. The operation of the electric telescopic rod (10) can drive the shaping head (7) to move down, so that the shaping head (7) moves down to the upper part of the outer side of the line to be shaped. The controller motor (6035) works, the displacement gear (6034) rotates, and the toothed plate (6033) meshing with it drives the displacement frame (603) to move, thereby driving the folding plate (600) to move. The moving beam (604) can then move laterally back and forth, thereby allowing the shaping head (7) to move laterally. After the electric telescopic rod (10) works again, the shaping head (7) moves down until it contacts the semi-finished product and produces a slight squeeze. S4: Finally, the controller controls the motor 2 (606) on the displacement mechanism (6) to work, which can drive the walking gear (608) on the drive shaft (607) to rotate. Since the walking gear (608) is meshed with multiple sets of meshing grooves (609) and the U-shaped slide frame (605) is limited by the sliding of the T-block (611) and the T-slot (610), the U-shaped slide frame (605) can move back and forth on the bottom wall of the moving beam (604), which drives the shaping head (7) to move back and forth. After the electric telescopic rod (10) works again, the shaping head (7) moves towards the shaping line until it is close to the side surface of the semi-finished product and generates a slight lateral squeeze, thus realizing the mounting and shaping of graphite sheets at different positions.
