Description

Technical Field

[0001] This invention relates to the field of graphite heat-conducting sheet technology, and more specifically to a processing apparatus and method for graphite heat-conducting sheets. Background Technology

[0002] Graphite thermal conductive sheets, as a high-performance heat conduction material, are widely used in the heat dissipation systems of electronic devices. Their excellent thermal conductivity, good flexibility, and chemical stability make them an ideal heat dissipation solution for portable electronic products such as smartphones, tablets, and laptops. Graphite thermal conductive sheets are usually shipped in large-size rolls or sheets. In order to meet the specific size and shape requirements of different electronic products, they need to be precisely slit.

[0003] A search revealed that CN217802553U discloses a slitting device for producing graphite heat sinks, comprising a fixed frame, a positioning mechanism, and a slitting mechanism; the positioning mechanism includes a first fixed box, which is fixedly connected to the bottom of the fixed frame, and the upper and lower walls on both sides of the first fixed box are respectively fixedly connected to the ends of two sleeve rods, each of the two sleeve rods being slidably fitted with a sliding sleeve, and the two sliding sleeves being respectively fixedly connected to the two side walls of a second fixed box; The above solution uses a rotary motor to drive the second threaded rod to rotate. The rotation of the second threaded rod causes the moving plate of the threaded sleeve to move. The moving plate slides on the guide rod of the sliding sleeve. The movement of the moving plate causes the pressure plate to move downward and contact the clamping plate, pressing the clamping plate downward. The second fixed box moves downward, and the sliding sleeve slides on the sleeve rod. The first spring is compressed, thereby causing the pressure plate to position and fix the graphite heat sink, preventing the graphite heat sink from moving. However, when using the positioning mechanism to position and fix the graphite heat sink, manual operation is required. This manual intervention mode not only significantly reduces production efficiency but also leads to unstable product quality. Since each cutting operation requires repetitive manual positioning and picking actions, it is difficult to maintain a stable production cycle. In addition, frequent manual contact not only increases labor intensity and labor costs but also poses a risk of equipment damage or material waste due to improper operation.

[0004] Therefore, it is of great importance to design a processing device and method for graphite heat-conducting sheets to solve the above-mentioned defects. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention presents a processing apparatus and method for graphite heat-conducting sheets. This processing apparatus and method aims to solve the technical problems of low production efficiency and unstable product quality caused by the need for manual positioning during the cutting of graphite heat sinks in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A processing apparatus for graphite thermal conductive sheets includes a base, a frame fixedly mounted on the top of the base, a positioning mechanism mounted on the top of the frame, a slitting frame fixedly mounted on the top of the frame and outside the positioning mechanism, and a stacking box fixedly mounted on the front end of the frame. The positioning mechanism includes a bracket fixedly installed at the middle of the top of the frame. Conveyor frames are slidably connected to both the left and right ends of the top of the frame.

A first motor is fixedly installed at the connection between the left side of the frame and the first bidirectional screw, and the drive end of the first motor is fixedly connected to the first bidirectional screw. The bottom of both sets of conveyor frames is threadedly connected to both ends of the first bidirectional screw through a first connecting sleeve. A first guide rod is fixedly installed at both the front and rear ends of the inside of the frame. The front and rear ends of the bottom of both sets of conveyor frames are slidably connected to the first guide rod through guide sleeves. A limit frame is fixedly installed at the far end of the top of both sets of conveyor frames.

[0007] As a preferred embodiment of the present invention, the bracket is internally rotatably connected to multiple sets of first rotating shafts, both sets of conveyor frames are internally equipped with conveyor belts, and both sets of limiting frames are rotatably connected to multiple sets of second rotating shafts on opposite sides.

[0008] As a preferred embodiment of the present invention, a collection hopper is fixedly installed at the bottom of the frame and below the cutting frame, and a first suction pipe is fixedly installed on the left side of the collection hopper.

[0009] As a preferred embodiment of the present invention, a movable frame is slidably connected to the front of the slitting frame, a second motor is fixedly installed at the left end of the top of the slitting frame, a transmission wheel is rotatably connected to the right end of the top of the slitting frame, a drive wheel is fixedly installed on the drive end of the second motor, a transmission belt is installed between the drive wheel and the transmission wheel, and the back of the movable frame is fixedly connected to the transmission belt through a fixed clamping plate. A lead screw linear module is installed on the front of the movable frame, and a cutting saw is fixedly installed on the front of the lead screw linear module.

[0010] As a preferred embodiment of the present invention, the upper and lower ends of the back of the movable frame are slidably connected to the cutting frame via guide rails, a dust suction hood is fixedly installed on the outer side of the cutting saw, and a second suction pipe is fixedly installed on the left side of the dust suction hood.

[0011] As a preferred embodiment of the present invention, the back of the stacking bin is fixedly connected to the frame via a mounting plate, and a guide frame is fixedly installed on the top of the stacking bin.

[0012] As a preferred embodiment of the present invention, the left and right ends of the stacking box are slidably connected to adjusting frames, the rear end of the top of the stacking box is rotatably connected to a second bidirectional screw, the top ends of the two sets of adjusting frames are threadedly connected to the two ends of the second bidirectional screw through a second connecting sleeve, and the top ends of the two sets of adjusting frames are slidably connected to the stacking box through a second guide rod.

[0013] As a preferred embodiment of the present invention, a rotating wheel is fixedly connected to the left end of the second bidirectional screw, and a locking knob is threadedly connected to the connection between the top of the stacking box and the second bidirectional screw, with the bottom end of the locking knob abutting against the outer side of the second bidirectional screw.

[0014] As a preferred embodiment of the present invention, both the upper and lower ends of the front of the two sets of adjustment frames are rotatably connected to transmission cylinders, and a transmission sleeve is sleeved between the two sets of transmission cylinders. Multiple sets of stacking plates are fixedly connected to the outer side of the transmission sleeve. A third motor is fixedly installed on the back of the adjustment frame, and the drive end of the third motor is fixedly connected to the rear end of one of the transmission cylinders. A material retrieval port is opened at the bottom of the front of the stacking box. To address the aforementioned technical problems, this invention also provides a method for processing graphite thermal conductive sheets, the specific steps of which are as follows: S1. Width Adjustment: The first motor is started to drive the first bidirectional screw according to the width of the graphite heat-conducting sheet. The distance between the conveyor frame and the limiting frame is precisely and synchronously adjusted through the cooperation of the first connecting sleeve and the guide sleeve, so as to realize the adaptive adjustment of graphite heat-conducting sheets of different widths. S2. Feeding and support: The uncut whole graphite heat-conducting sheet is placed on the positioning mechanism from the rear end of the frame. The middle section of the graphite heat-conducting sheet is supported by the bracket. The friction is reduced by the internal first rotating shaft, which facilitates movement. S3. Conveying and Limiting: The start-up conveyor belt provides active driving force, which drives the graphite heat-conducting sheet to be conveyed smoothly and at a constant speed to the front end of the frame. The limit frame, together with the second rotating shaft, prevents lateral deviation and avoids scratches, ensuring the accuracy of linear conveying. S4. Cutting and Dust Removal: After the graphite heat-conducting sheet is in place, the second motor is started to drive the drive wheel to rotate. The transmission wheel and transmission belt drive the moving frame to move laterally and cooperate with the lead screw linear module to press down the cutting saw. The dust collection hood collects cutting dust in real time, and the collection hopper works with the first suction pipe to remove scattered particles. S5. Stacking and Collection: After slitting, the finished products fall into the stacking box and are automatically stacked through the adjustment frame and transmission sleeve. The operator takes out the finished products from the material outlet, completing the fully automated operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, through the coordinated design of the positioning mechanism and the slitting frame, the operator first starts the first motor to drive the first bidirectional screw to rotate according to the width of the graphite heat-conducting sheet to be slit. Through the cooperation of the first connecting sleeve and guide sleeve at the bottom of the two sets of conveyor frames, the distance between the left and right sets of conveyor frames and their top limiting frames is precisely and synchronously adjusted to accommodate graphite heat-conducting sheets of different widths. Then, the unslit whole graphite heat-conducting sheet is placed from the rear end of the frame onto the positioning mechanism. The middle section of the graphite heat-conducting sheet is supported by the bracket, and multiple sets of first rotating shafts inside help reduce friction. The system is easy to move, and the conveyor belts inside the two sets of conveyor frames located below both ends of the graphite heat-conducting sheet provide active driving force, driving the graphite heat-conducting sheet to be smoothly and uniformly transported to the front end of the frame. During this process, the two sides of the graphite heat-conducting sheet are constrained by the limiting frame, and the multiple sets of second rotating shafts on the opposite side of the limiting frame contact the side of the graphite heat-conducting sheet, changing the lateral sliding friction into rolling friction, effectively preventing lateral deviation and avoiding scratches. This solves the problems of low efficiency and inaccurate positioning caused by manual operation, thereby improving production efficiency and product quality consistency.

[0016] 2. In this invention, through the design of the stacking box, after cutting, the graphite heat-conducting sheets of the required specifications are conveyed and fall into the stacking box in front. The guide frame at the top of the box acts as a guide to prevent accumulation at the inlet. Before collection begins, the operator loosens the locking knob, rotates the wheel to drive the second bidirectional screw to rotate, and drives the adjusting frame to slide along the second guide rod through two sets of second connecting sleeves. The distance between the two sets of adjusting frames is adjusted to match the width of the finished product. After adjustment, the locking knob is tightened again. After the width adjustment is completed, the automatic stacking program is started. The finished graphite heat-conducting sheets falling from the guide frame fall into the support space formed by two sets of transmission cylinders, transmission sleeves and multiple sets of stacking plates. The third motor drives the stacking box to... A set of transmission cylinders rotates, driving the transmission sleeve and the stacking plate on it to perform intermittent stepping motion, realizing the automatic, orderly, and single-piece separation stacking of finished products. When a batch is processed, the operator can directly take out the neatly stacked stack of finished products from the front material picking port at once. This realizes the fully automatic and orderly collection and temporary storage of finished products after cutting, replacing the heavy labor of manual picking and placing after each slice in the traditional process. This greatly reduces labor intensity and labor costs, while ensuring the neatness and uniformity of the finished product stacking, avoiding the chaos, scratches or omissions that may be caused by manual collection, and significantly improving the automation level, operation efficiency and product management quality of the end link of the production process.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to 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.

[0020] Example: Please refer to Figures 1-7 The present invention provides a technical solution: A processing apparatus for graphite heat-conducting sheets includes a base 1, a frame 2 fixedly installed on the top of the base 1, a positioning mechanism 3 installed on the top of the frame 2, a slitting frame 4 fixedly installed on the top of the frame 2 and outside the positioning mechanism 3, and a stacking box 5 fixedly installed at the front end of the frame 2.

[0021] First, in this embodiment, the specific structure of the positioning mechanism 3 is as follows: The positioning mechanism 3 includes a bracket 301 fixedly installed at the middle of the top of the frame 2. Conveyor frames 302 are slidably connected to both ends of the top of the frame 2. A first bidirectional screw 303 is rotatably connected to the middle of the interior of the frame 2. A first motor 304 is fixedly installed at the connection point between the left side of the frame 2 and the first bidirectional screw 303, and the drive end of the first motor 304 is fixedly connected to the first bidirectional screw 303. The bottoms of both sets of conveyor frames 302 are threadedly connected to both ends of the first bidirectional screw 303 via first connecting sleeves 305. The interior of the frame 2... Both ends of the conveyor frame 302 are fixedly installed with first guide rods 306. The bottom ends of the two conveyor frames 302 are slidably connected to the first guide rods 306 via guide sleeves 307. The top ends of the two conveyor frames 302 that are far apart are fixedly installed with limit frames 308. First, according to the width of the graphite heat-conducting sheet to be cut, the first motor 304 is started to drive the first bidirectional screw 303 to rotate. Since the bottom of the two conveyor frames 302 is threadedly connected to the two ends of the first bidirectional screw 303 via the first connecting sleeve 305, and the bottom of the conveyor frame 302 is guided by the first guide rods 306, the conveyor frames 302 are slidably connected to the first guide rods 306 via guide sleeves 307. The sleeve 307 is slidably connected to the first guide rod 306 fixed inside the frame 2. Therefore, the rotation of the first bidirectional screw 303 will precisely and synchronously drive the left and right sets of conveyor frames 302 to move towards or away from each other along the first guide rod 306, thereby adjusting the distance between the two sets of conveyor frames 302 and the limiting frame 308 at their top to accommodate graphite heat-conducting sheets of different widths. Then, the uncut whole graphite heat-conducting sheet is placed on the positioning mechanism 3 from the rear end of the frame 2. The middle section of the graphite heat-conducting sheet is first supported on the bracket 301, and then the conveying is started. The frame 302 smoothly conveys the graphite heat-conducting sheet on it to the front end of the frame 2. During the conveying process, the two sides of the graphite heat-conducting sheet are constrained by two sets of limiting frames 308 to prevent it from shifting in the horizontal plane. Then, the graphite heat-conducting sheet is accurately conveyed to the predetermined cutting position below the slitting frame 4, realizing automatic width adjustment, automatic feeding and conveying and precise positioning of the graphite heat-conducting sheet. The whole process does not require manual adjustment or repeated positioning, which significantly improves production efficiency and ensures the consistency and high precision of the material position before each slitting.

[0022] Furthermore, the bracket 301 has multiple sets of first rotating shafts 309 rotatably connected internally, and both sets of conveyor frames 302 are equipped with conveyor belts 310. Both sets of limiting frames 308 have multiple sets of second rotating shafts 311 rotatably connected to opposite sides. When the middle section of the graphite heat-conducting sheet is supported on the bracket 301, the multiple sets of first rotating shafts 309 inside the bracket help reduce friction and facilitate movement. The two sets of conveyor frames 302 located below both ends of the graphite heat-conducting sheet are equipped with conveyor belts 310. After startup, the conveyor belts 310 operate, providing active and controllable driving force to move the graphite heat-conducting sheet on them. The graphite heat-conducting sheet is smoothly and uniformly conveyed to the front end of the frame 2. During the conveying process, the two sides of the graphite heat-conducting sheet are constrained by two sets of limiting frames 308 fixed at the top of the conveying frame 302. Multiple sets of second rotating shafts 311 rotatably connected to the opposite side of the limiting frames 308 contact the sides of the graphite heat-conducting sheet. These second rotating shafts 311 also convert the lateral sliding friction into rolling friction. While effectively preventing the graphite heat-conducting sheet from shifting laterally in the horizontal plane and ensuring the accuracy of linear conveying, it also minimizes the possibility of scratches or material damage to the sides of the graphite heat-conducting sheet caused by friction.

[0023] Then, a collection hopper 201 is fixedly installed at the bottom of the frame 2 and below the slitting frame 4. A first suction pipe 202 is fixedly installed on the left side of the collection hopper 201. When the slitting process is carried out, some of the graphite particles and debris generated by the cutting will fall naturally under the action of gravity. The falling dust and debris are received and concentrated by the bucket-shaped structure of the collection hopper 201. The first suction pipe 202 on the left side of the collection hopper 201 is connected to an external negative pressure dust removal system (such as a central dust collector or an industrial vacuum cleaner). After the dust removal system is started, the graphite dust accumulated in the collection hopper 201 is continuously drawn away by the suction force generated by the first suction pipe 202 and transported to a designated dust collection device for unified treatment to prevent it from accumulating inside the device.

[0024] Furthermore, a movable frame 401 is slidably connected to the front of the slitting frame 4. A second motor 402 is fixedly installed at the left end of the top of the slitting frame 4, and a transmission wheel 403 is rotatably connected to the right end of the top of the slitting frame 4. A drive wheel 404 is fixedly installed on the drive end of the second motor 402. A transmission belt 405 is installed between the drive wheel 404 and the transmission wheel 403. The back of the movable frame 401 is fixedly connected to the transmission belt 405 through a fixed clamping plate 406. A lead screw linear module 407 is installed on the front of the movable frame 401. A cutting saw 408 is fixedly mounted on the front of the lead screw linear module 407. When the graphite heat-conducting sheet is positioned and conveyed to the designated position below the slitting frame 4, the slitting process is started. First, the second motor 402 drives the drive wheel 404 to rotate. With the cooperation of the transmission wheel 403, the transmission belt 405 is driven to move the moving frame 401 laterally along the slitting frame 4. Then, the lead screw linear module 407 on the moving frame 401 drives the cutting saw 408 to press down in a direction perpendicular to the conveying direction to cut the graphite heat-conducting sheet below.

[0025] The upper and lower ends of the back of the movable frame 401 are slidably connected to the slitting frame 4 via guide rails 409. A dust hood 410 is fixedly installed on the outside of the cutting saw 408, and a second suction pipe 411 is fixedly installed on the left side of the dust hood 410. The movable frame 401 moves laterally and precisely along the guide rails 409 on its back to determine the longitudinal starting position of each cutting line. During the entire sawing process, the cutting saw 408 is connected to an external negative pressure system through the dust hood 410 and the second suction pipe 411 to collect the fine graphite dust generated in the cutting area in real time and efficiently.

[0026] Furthermore, the back of the stacking box 5 is fixedly connected to the frame 2 via the mounting plate 501, and a guide frame 502 is fixedly installed on the top of the stacking box 5. After the current graphite heat-conducting sheet is cut, the graphite heat-conducting sheet of the required specifications is conveyed and falls into the stacking box 5 in front. The guide frame 502 on the top of the stacking box 5 plays a guiding role to ensure that the graphite heat-conducting sheet can be guided into the stacking system inside the stacking box 5, preventing it from accumulating or getting stuck at the inlet.

[0027] Secondly, adjusting brackets 503 are slidably connected to both the left and right ends of the stacking box 5. A second bidirectional screw 504 is rotatably connected to the rear end of the top of the stacking box 5. The top ends of both sets of adjusting brackets 503 are threadedly connected to both ends of the second bidirectional screw 504 through a second connecting sleeve 505, and the top ends of both sets of adjusting brackets 503 are slidably connected to the stacking box 5 through a second guide rod 506. A rotating wheel 507 is fixedly connected to the left end of the second bidirectional screw 504. A locking knob 508 is threadedly connected to the connection between the top of the stacking box 5 and the second bidirectional screw 504, and the bottom end of the locking knob 508 abuts against the outer side of the second bidirectional screw 504. Before collecting finished graphite heat-conducting sheets of different specifications, the operator needs to adjust the effective width inside the stacking box 5 and loosen the locking knob 508 to release the first... Locking the double-direction screw 504, then manually rotating the wheel 507 to drive the second double-direction screw 504 to rotate, driving the adjusting brackets 503 at both ends through the two sets of second connecting sleeves 505, so that they slide synchronously towards or away from each other along the second guide rod 506, thereby changing the distance between the two sets of adjusting brackets 503. After adjusting to match the width of the finished graphite heat-conducting sheet, tighten the locking knob 508 to fix the position of the second double-direction screw 504 and the adjusting brackets 503, completing the width preset. This achieves quick, manual and stable adjustment of the collection width of finished graphite heat-conducting sheets of different sizes. Moreover, its structure is simple and reliable, and the adjustment accuracy meets the stacking requirements, giving the equipment good versatility and flexibility. There is no need to equip each specification of finished product with a special collection box, reducing the complexity of the equipment and the cost of use.

[0028] Finally, transmission cylinders 509 are rotatably connected to the upper and lower ends of the front of both sets of adjusting frames 503. A transmission sleeve 510 is fitted between the two sets of transmission cylinders 509. Multiple stacking plates 511 are fixedly connected to the outer side of the transmission sleeve 510. A third motor 512 is fixedly installed on the back of the adjusting frame 503, and the drive end of the third motor 512 is fixedly connected to the rear end of one of the transmission cylinders 509. A material dispensing port 513 is opened at the bottom of the front of the stacking box 5. After the width adjustment is completed, the automatic stacking program is started. The finished graphite heat-conducting sheet falling from the guide frame 502 first falls into the support space formed by the two sets of transmission cylinders 509, the transmission sleeve 510 and the multiple stacking plates 511 on it. The third motor 512 starts, driving one of the transmission cylinders 509 to rotate, which in turn drives the transmission sleeve 510 and the stacking plates 511 on it to perform intermittent stepping motion. Whenever a stacking plate 511 moves to When the device is in the upper horizontal position, it receives a finished graphite heat-conducting sheet. Then, the transmission sleeve 510 steps forward to move the finished sheet to the next stacking pallet 511 for temporary storage. At the same time, a new empty stacking pallet 511 moves to the receiving position to wait for the next finished graphite heat-conducting sheet. This cycle is repeated to achieve automatic, orderly, and single-sheet separate stacking of finished products. When a batch is processed, the operator can directly take out the neatly stacked stack of finished products from the front picking port 513 at once, simulating the action of manually stacking single sheets. This realizes the fully automatic and orderly collection and temporary storage of finished products after cutting, replacing the heavy labor of manually picking and placing each sheet after cutting in the traditional process. This greatly reduces labor intensity and labor costs, while ensuring the neatness and uniformity of the finished product stacking. It avoids the chaos, scratches or omissions that may be caused by manual collection, and significantly improves the automation level, operation efficiency and product management quality of the end link of the production process.

[0029] In this embodiment, the specific implementation scenario is as follows: The operator first starts the first motor 304 to drive the first bidirectional screw 303 to rotate according to the width of the graphite heat-conducting sheet to be cut. Through the cooperation of the first connecting sleeve 305 and the guide sleeve 307 at the bottom of the two sets of conveyor frames 302, the distance between the left and right sets of conveyor frames 302 and their top limiting frames 308 is precisely and synchronously adjusted to accommodate graphite heat-conducting sheets of different widths. Subsequently, the uncut whole graphite heat-conducting sheet is placed from the rear end of the frame 2 onto the positioning mechanism 3. The middle section of the graphite heat-conducting sheet is supported by the bracket 301, and the multiple sets of first rotating shafts 309 inside help reduce friction and facilitate movement. At the same time, the conveyor belts 310 inside the two sets of conveyor frames 302 located below both ends of the graphite heat-conducting sheet rotate, providing active... The driving force propels the graphite heat-conducting sheet smoothly and at a constant speed towards the front end of the frame 2. During this process, the two edges of the graphite heat-conducting sheet are constrained by the limiting frame 308. Meanwhile, multiple sets of second rotating shafts 311 on the opposite side of the limiting frame 308 contact the sides of the graphite heat-conducting sheet, converting lateral sliding friction into rolling friction, effectively preventing lateral deviation and avoiding scratches. When the graphite heat-conducting sheet is accurately transported to the predetermined cutting position below the slitting frame 4, the slitting process begins. The second motor 402 drives the drive wheel 404 to rotate, which in turn drives the moving frame 401 to move laterally along the slitting frame 4 via the transmission wheel 403 and the transmission belt 405. Subsequently, the linear screw module 407 on the moving frame 401 drives the cutting saw 408 to press down, cutting the graphite heat-conducting sheet. Simultaneously, the moving frame 401... 1. The guide rail 409 on the back is slidably connected to the slitting frame 4 to ensure precise movement. The dust suction hood 410 on the outside of the cutting saw 408 is connected to the external negative pressure system through the second suction pipe 411 to collect fine dust in the cutting area in real time. Some of the graphite particles and debris generated during cutting fall naturally under gravity and are caught by the collection hopper 201 at the bottom of the frame 2. They are then drawn away by the negative pressure dust removal system connected to the first suction pipe 202 on its left side to prevent accumulation. After cutting is completed, the graphite heat-conducting sheet of the required specifications falls into the stacking box 5 in front through the conveyor. The guide frame 502 on the top of the stacking box 5 guides the material and prevents accumulation at the inlet. Before collection begins, the operator loosens the locking knob 508 and rotates the rotating wheel 507 to drive the second bidirectional screw 504 to rotate. The connecting sleeve 505 drives the adjusting frame 503 to slide along the second guide rod 506, adjusting the distance between the two sets of adjusting frames 503 to match the width of the finished product. After adjustment, the locking knob 508 is tightened again. After the width adjustment is completed, the automatic stacking program is started. The finished graphite heat-conducting sheet falling from the guide frame 502 falls into the support space formed by the two sets of transmission cylinders 509, the transmission sleeve 510 and the multiple sets of stacking plates 511 on it. The third motor 512 drives one of the transmission cylinders 509 to rotate, driving the transmission sleeve 510 and the stacking plates 511 on it to perform intermittent stepping motion, realizing the automatic, orderly, and single-piece separation stacking of the finished products. When a batch is processed, the operator can directly take out the neatly stacked stack of finished products at once from the front material picking port 513.The entire operation process is simple and convenient. This invention solves the problems of low production efficiency and unstable product quality caused by manual operation in existing technologies, and realizes efficient and precise automated processing of graphite heat-conducting sheets.

[0030] This invention also provides a method for processing graphite thermal conductive sheets, the specific operation steps of which are as follows: S1. Width adjustment: The first motor 304 is started to drive the first bidirectional screw 303 according to the width of the graphite heat-conducting sheet. The distance between the conveyor frame 302 and the limiting frame 308 is precisely and synchronously adjusted through the cooperation of the first connecting sleeve 305 and the guide sleeve 307, so as to realize the adaptive adjustment of graphite heat-conducting sheets of different widths. S2, Feeding and Support: The uncut whole graphite heat-conducting sheet is placed from the rear end of the frame 2 onto the positioning mechanism 3. The middle section of the graphite heat-conducting sheet is supported by the bracket 301. Friction is reduced by the internal first rotating shaft 309, which facilitates movement. S3. Conveying and Limiting: The starting conveyor belt 310 provides active driving force, which drives the graphite heat-conducting sheet to be conveyed smoothly and at a constant speed to the front end of the frame 2. The limiting frame 308 cooperates with the second rotating shaft 311 to prevent lateral deviation and avoid scratches, ensuring the accuracy of linear conveying. S4. Cutting and dust removal: After the graphite heat-conducting sheet is in place, the second motor 402 is started to drive the drive wheel 404 to rotate. The transmission wheel 403 and the transmission belt 405 drive the moving frame 401 to move laterally and cooperate with the lead screw linear module 407 to press down the cutting saw 408. The dust collection hood 410 collects cutting dust in real time, and the collection hopper 201 cooperates with the first suction pipe 202 to remove scattered particles. S5. Stacking and Collection: After slitting, the finished products fall into the stacking box 5. Automatic stacking is achieved through the adjusting frame 503 and the transmission sleeve 510. The operator takes out the finished products from the material outlet 513, completing the fully automated operation.
