[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Figure 1 This is a schematic diagram of the structure of an asynchronous cutting device for thermal pads according to some embodiments of this disclosure. Figure 1 It includes a conveying assembly 1, a peeling plate 2, a cutting assembly 3, a cutting blade 32, a blade carrier 31, a detection assembly 5, a platform 6, rolling wheels 7, a first slide rail 8, a second slide rail 9, a second winding device 10, a first winding device 11, a carrying film 12, a heat-conducting pad 13, a cover film 14, a first pressure shaft 101, and a second pressure shaft 102.

[0025] In some embodiments, the asynchronous cutting device for thermally conductive sheets includes a conveying assembly 1, a peeling plate 2, a stage 6, a carrying film 12, a cutting assembly 3, a recycling assembly, a control assembly, and a detection assembly 5. The control assembly is not shown in the accompanying drawings. The conveying assembly 1 can be disposed at the front end of the peeling plate 2, and is configured to convey the thermally conductive pad 13. It should be noted that the thermally conductive pad 13 can be a continuous thermally conductive pad of fixed width. For example, the thermally conductive pad 13 can be a continuous thermally conductive silicone sheet with a width of 10 cm. The conveying assembly 1 can be a motor-driven roller, the surface of which is covered with a silicone anti-slip pad, and the rotation of the roller can drive the thermally conductive pad 13 forward. The peeling plate 2 can be a stainless steel metal plate with a smooth surface, allowing for smooth conveying of the thermally conductive pad 13. The end of the peeling plate 2 that first contacts the thermally conductive pad 13 can be considered the front end, and the opposite end the rear end.

[0026] In some embodiments, the peeling plate 2 is disposed at the front end of the stage 6, and a first gap is provided between the peeling plate 2 and the stage 6. The stage 6 can be a horizontally placed support platform, and its surface can be used to support the carrying film 12. The carrying film 12 can be a continuous film of fixed width. For example, the carrying film 12 can be a continuous PET film with a width of 10.5 cm. The width of the carrying film 12 is greater than the width of the thermal pad 13, which can better support the cut thermal pad. The end of the stage 6 adjacent to the rear end of the peeling plate 2 can be designated as the front end of the stage 6, and the opposite end as the rear end. The rear end of the peeling plate 2 does not contact the front end of the stage 6, and the distance between the rear end of the peeling plate 2 and the front end of the stage 6 is designated as the first gap. The first gap can be 1 cm. The carrying film 12 is configured to be placed on the surface of the stage 6, passing through the first gap and adhering to the front end of the stage 6. The aforementioned carrier film 12 is relatively thin and can pass through the aforementioned first gap. For example, the thickness of the aforementioned carrier film 12 can be 12 μm. The aforementioned carrier film 12 can be located below the aforementioned peeling plate 2, and the aforementioned carrier film 12 can pass through the aforementioned first gap and be placed on the surface of the aforementioned stage 6 for supporting the cut thermally conductive pad.

[0027] In some embodiments, the cutting assembly 3 may include a cutting blade 32 and a blade carrier 31. The cutting blade 32 may be a carbide blade, and its width is greater than the width of the heat-conducting pad 13, allowing it to completely cover the cutting area when cutting the heat-conducting pad 13. The blade carrier 31 may be square and can be lifted and lowered pneumatically or electrically; no specific limitation is made here. The blade carrier 31 may be located above the platform 6. The cutting blade 32 may be mounted on the blade carrier 31. A blade holder is provided on the side of the blade carrier 31 near the front end of the platform 6. The blade holder may be a square protrusion. A mounting hole is provided on the side of the blade holder perpendicular to the surface of the platform 6, near the front end of the platform 6, and a corresponding hole is provided on the cutting blade 32. Specifically, the hole of the cutting blade 32 can be aligned with the mounting hole of the blade holder. In this case, the blade of the cutting blade 32 is closer to the surface of the stage 6 than the blade holder, facilitating the cutting of the heat-conducting pad 13. Then, screws are used to fix the cutting blade 32 to the blade holder, making the cutting blade 32 perpendicular to the surface of the stage 6, resulting in a smoother cut on the heat-conducting pad 13. In practice, the cutting blade 32 can be used to cut the heat-conducting pad 13 by raising and lowering the blade carrier 31. The cutting blade 32 can be positioned above the front end of the stage 6. When cutting the heat-conducting pad 13, the blade carrier 31 moves downwards, causing the cutting blade 32 to move downwards to achieve the cut. Simultaneously, the blade holder can contact the cut heat-conducting pad, applying pressure to it, allowing the cut heat-conducting pad to adhere to the substrate film 12.

[0028] In some embodiments, the recycling assembly includes a roller 7 and a first winding device 11 for conveying and winding up the carrier film 12. The roller 7 can be a motor-driven roller with a silicone anti-slip pad on its surface, allowing the carrier film 12 to move linearly via rotation. The first winding device 11 can be a cylinder with baffles at both ends and a hollow structure in the middle, which can be nested on a motor-driven reel. The reel drives the first winding device 11 to rotate, winding up the carrier film 12. The roller 7 is located at the rear end of the stage 6. The roller 7 is configured to move the carrier film 12 via rotation. The first winding device 11 is located at the rear end of the roller 7 and is configured to wind up the carrier film 12. The detection assembly can be a CCD detection device. The detection assembly 5 includes a camera, which is vertically positioned above the stage 6 and can capture images of the cut thermal pads. These images are used to detect the dimensions of the cut thermal pads.

[0029] In some embodiments, the control components are communicatively connected to the conveying component 1, the cutting component 3, the detection component 5, and the recycling component, respectively. The control components may include a controller. The controller may be a PLC, used to control the operation of the asynchronous cutting device for thermal pads. Specifically, the size of the thermal pad can be preset before starting. For example, the preset thermal pad size may be 10cm × 2cm. Then, the conveying component 1 can be controlled to convey the thermal pad 13. The thermal pad 13 may be a continuous thermally conductive silicone sheet with a width of 10cm. The thermal pad 13 passes through the peeling plate 2 to the front end of the stage 6, located below the cutting blade 32. At this time, the blade carrier 31 moves downward, driving the cutting blade 32 downward to achieve cutting. Simultaneously, the blade holder can contact the cut thermal pad, applying pressure to the cut thermal pad, which can adhere the cut thermal pad to the carrier film 12. Then, the rolling wheel 7 can pull the carrier film 12 forward a predetermined distance. The predetermined distance can be 2.5cm, ensuring a 5mm gap between the two cut thermal pads. This prevents the cut thermal pads from sticking together due to excessive spacing, while also preventing waste of the carrier film 12 due to excessive spacing. Then, the size of the cut thermal pads is detected by the detection component 5. Finally, the carrier film 12 pulled by the roller 7 is wound up by the first winding device 11. It should be noted that the conveying component 1 can convey the thermal pad 13 a distance of 2cm each time, ensuring that the size of the cut thermal pads obtained after each cut conforms to the preset thermal pad size. Repeating the above actions achieves the cutting, detection, and winding of the thermal pads, improving the efficiency of placing the cut thermal pads. It should be noted that the first cut can be an alignment cut, meaning the size of the thermal pad after the first cut does not necessarily have to be the preset thermal pad size. During the second cut, the conveying component 1 conveys the thermal pad 13 by 2cm, ensuring that the cut thermal pad conforms to the preset thermal pad size.

[0030] Optionally, the conveying assembly 1 includes a first pressure shaft 101 and a second pressure shaft 102. Both the first pressure shaft 101 and the second pressure shaft 102 can be rollers, used to convey the heat-conducting pad 13. The first pressure shaft 101 and the second pressure shaft 102 are placed vertically, with the first pressure shaft 101 positioned above the second pressure shaft 102. A second gap exists between the first pressure shaft 101 and the second pressure shaft 102. The first pressure shaft 101 and the second pressure shaft 102 are not in contact. The distance between the first pressure shaft 101 and the second pressure shaft 102 can serve as the second gap. The second gap can be the same as the thickness of the heat-conducting pad 13, allowing the heat-conducting pad 13 to pass through it.

[0031] Optionally, the first pressure roller 101 and the second pressure roller 102 are configured to transport the thermally conductive pad 13 to the peeling plate 2 by rotating in the opposite direction. Specifically, the first pressure roller 101 can rotate clockwise, and the second pressure roller 102 can rotate counterclockwise, transporting the thermally conductive pad 13 through the second gap to the peeling plate 2. One side of the thermally conductive pad 13 is covered with an original film to prevent it from sticking to the peeling plate 2. The original film can be a PET film. The original film is configured to be separable from the thermally conductive pad 13. The original film contacts the peeling plate 2, and the peeling plate 2 can peel the thermally conductive pad 13 from the original film. Specifically, the original film can pass through the first gap while adhering to the peeling plate 2, and the thermally conductive pad 13 can be transported to the front end of the stage 6 to achieve the peeling of the thermally conductive pad 13 from the original film. The original film is thin enough to pass through the first gap. For example, the thickness of the original film can be 12 μm. The thermal pad 13 is configured to adhere to the carrier film 12. The carrier film 12 is made of the same material as the original film and can also adhere to the thermal pad 13.

[0032] Optionally, the recycling assembly may further include a second winding device 10. The second winding device 10 may be a cylinder with baffles at both ends and a hollow structure in the middle, which can be nested on a motor-driven reel. The second winding device 10 is located below the conveying assembly 1 and is configured to wind up the original film. The original film can be wound up by rotating the reel, which drives the second winding device 10 to rotate.

[0033] Optionally, the aforementioned asynchronous cutting device for thermally conductive pads further includes a cutting pad. This cutting pad is not shown in the accompanying drawings. The cutting pad can be a polyurethane board, which can buffer the impact force generated during cutting and protect the surface of the platform 6. The cutting pad can be placed on the surface of the platform 6, and can be located below the cutting blade 32.

[0034] Optionally, anti-slip pads are provided at both ends of the aforementioned roller 7. These anti-slip pads are not shown in the accompanying drawings. The anti-slip pads can be annular silicone pads, nested at both ends of the roller 7, increasing the friction between the anti-slip pads and the carrier film 12. The spacing of the anti-slip pads can be the same as the width of the thermally conductive pad 13, preventing the anti-slip pads from squeezing the cut thermally conductive pad. The anti-slip pads are configured to move the carrier film 12. Specifically, the roller 7 can move the carrier film 12 while rolling using the anti-slip pads, and the anti-slip pads have a certain height to prevent the roller 7 from squeezing the cut thermally conductive pad and to prevent displacement of the cut thermally conductive pad.

[0035] Optionally, the aforementioned asynchronous cutting device for thermally conductive pads further includes a cover film 14. The cover film 14 can be a PET film, used to cover the cut thermally conductive pads to prevent them from sticking together when rolled up by the first winding machine 11. The cover film 14 is positioned above the first winding machine 11. The cover film 14 has the same width as the carrier film 12, and is configured to be rolled up together with the carrier film 12 by the first winding machine 11, allowing the rolled-up carrier film 12 and cover film 14 to be flush, facilitating storage and transportation.

[0036] Optionally, the aforementioned asynchronous cutting device for thermal pads further includes a first slide rail 8 and a second slide rail 9. The first slide rail 8 can be a guide rail used to constrain the movement trajectory of the thermal pad 13. The first slide rail 8 can be located on the peeling plate 2. The thermal pad 13 can be placed within the first slide rail 8, and the thermal pad 13 can move along the track of the first slide rail 8. The second slide rail 9 can be a guide rail used to constrain the movement trajectory of the carrier film 12. The second slide rail 9 can be disposed on the surface of the stage 6, and the second slide rail 9 is located below the detection component 5, facilitating the size detection of the cut thermal pad. The carrier film 12 can be placed within the second slide rail 9, and the carrier film 12 can move along the track of the second slide rail 9.

[0037] Furthermore, in the process of solving the technical problems mentioned in the background art using technical solutions, the inventors discovered that during the cutting of thermal pads, the thermal pads are soft and will shift during cutting, resulting in low dimensional accuracy of the cut thermal pads. In order to improve cutting accuracy, and in conjunction with the technology possessed by the inventors' company, the following solution was adopted.

[0038] Optionally, the peeling plate 2 is located above the carrier film 12, facilitating the passage of the carrier film 12 through the first gap. The thermal pad 13 is configured to hang naturally after separation from the original film but without contacting the carrier film 12. Specifically, the peeling plate 2 and the carrier stage 6 may not be on the same plane; the peeling plate 2 may be higher than the carrier stage 6, providing a suspended transition area for the thermal pad 13 after separation from the original film, preventing the thermal pad 13 from prematurely contacting the carrier film 12 and causing positional displacement. The cutting blade 32 includes a first cutting blade and a second cutting blade. Both the first and second cutting blades can be carbide blades, and their widths are greater than the width of the thermal pad 13, allowing complete coverage of the cutting area when cutting the thermal pad 13. The first and second cutting blades are arranged parallel to each other on the blade holder of the blade carrier 31. Specifically, mounting holes are provided on both opposite sides of the blade holder perpendicular to the surface of the platform 6. Holes are also provided at corresponding positions for the first and second cutting blades, allowing screws to be used to fix the first and second cutting blades to the two sides of the blade holder. The direction in which the conveying assembly 1 conveys the heat-conducting pad 13 is perpendicular to the first and second cutting blades, resulting in a smoother cut. The first and second cutting blades are configured to cut the heat-conducting pad 13, separated from the original membrane, into heat-conducting pads of a fixed width. The width of the blade holder can be designed according to the preset heat-conducting pad size. For example, the preset heat-conducting pad size can be 10cm × 2cm, and the distance between the two sides of the blade holder where the first and second cutting blades are mounted can be 2cm. The blade holder and the blade carrier 31 are detachably connected. Specifically, the blade carrier 31 can be provided with a guide groove, which faces vertically upwards. A guide rod is provided at the corresponding position of the aforementioned blade holder, and the guide rod can be embedded in the aforementioned guide groove. The aforementioned guide rod has a threaded hole. A hole is provided at the corresponding position of the aforementioned guide groove, and the direction of the hole is perpendicular to the direction of the guide groove. The aforementioned blade holder can be fixed by inserting a screw through the hole into the threaded hole of the aforementioned guide rod. An anti-sticking gasket is provided between the aforementioned first cutting blade and the aforementioned second cutting blade. The aforementioned anti-sticking gasket can be a gasket made of elastic material, including but not limited to polytetrafluoroethylene and silicone rubber. During cutting, the aforementioned anti-sticking gasket can contact the thermally conductive pad 13 before the cutting blade, in order to prevent the cut thermally conductive pad from sticking between the aforementioned first cutting blade and the aforementioned second cutting blade. The aforementioned anti-sticking gasket is configured to press the aforementioned fixed-width thermally conductive pad onto the carrier film 12. Specifically, when cutting the thermally conductive pad 13, the aforementioned anti-sticking gasket contacts the thermally conductive pad 13 before the cutting blade, and can generate vertical pressure through elastic deformation to press the cut thermally conductive pad tightly onto the surface of the aforementioned carrier film 12.The parallel placement of the first and second cutting blades allows for higher dimensional accuracy of the cut thermal pads.

[0039] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "low dimensional accuracy of the cut thermal pad". Factors leading to low dimensional accuracy of the cut thermal pad often include: using a single blade to cut the thermal pad; the thermal pad being soft and prone to displacement during cutting, resulting in low dimensional accuracy. Solving these factors can improve the dimensional accuracy of the cut thermal pad. To achieve this, this disclosure uses parallel double cutting blades to cut the thermal pad and uses an anti-stick pad to press the cut thermal pad onto the surface of the carrier film, preventing displacement during cutting and improving cutting accuracy.

The cutter can directly cut the thermal pads onto the film. Then, the roller pulls the film forward, leaving a space for the cut thermal pad. The detection assembly then detects the size of the cut thermal pad on the film and the first winding device winds up the film pulled by the roller. Then, the conveying component transports the thermal pads to the bottom of the cutting blade. Repeating the above actions can eliminate the placement step and improve the efficiency of placing the cut thermal pads.
