[0003] Traditional processing and cutting methods are prone to producing burrs and uneven edges during the cutting process. Furthermore, thermally conductive silicone is easily deformed by high temperatures during cutting, leading to a decline in material performance. During processing, the thermally conductive silicone material is prone to movement, which can reduce cutting accuracy or even result in scrap. If the heat generated during cutting cannot be dissipated in time, it will accumulate inside the material, causing localized overheating and further affecting the material's physical properties and service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4A device for improving the processing edge quality of thermally conductive silicone includes a processing table 1, a laser cutting head 2, a cooling device, a fixing device, and an adjusting device. A cutting table 3 is mounted at the top center of the processing table 1. The cooling device is installed inside the cutting table 3. The fixing device is mounted at the bottom end of the cutting table 3. A support frame 4 is mounted at the top of the processing table 1. The laser cutting head 2 is mounted on the bottom wall of the support frame 4 via the adjusting device. The cooling device includes a circulation pipe 5, a circulation pump 6, and a cooling unit 7. The circulation pipe 5 is arranged inside the processing table 1. The cooling unit 7 is mounted on the back wall of the support frame 4. Both ends of the circulation pipe 5 penetrate the side wall of the cutting table 3 and the support frame, respectively. The sidewall of the support frame 4 is connected to the refrigeration unit 7. The circulation pump 6 is installed on the outer wall of the circulation pipe 5. The fixing device includes a bidirectional screw 8, a movable seat 9, an L-shaped rod 10, a fixing block 11, and a first motor 12. A rectangular groove is opened laterally at the top of the processing table 1. The bidirectional screw 8 is rotatably installed in the rectangular groove. The movable seat 9 is threaded on both the left and right ends of the bidirectional screw 8. The L-shaped rod 10 is installed at the top of each of the two sets of movable seats 9. The fixing block 11 is installed on the corresponding sidewall of each of the two sets of L-shaped rods 10. The first motor 12 is installed through the sidewall of the rectangular groove at one end of the bidirectional screw 8. The control system 13 is installed on the front sidewall of the support frame 4. In this example, during use, the thermally conductive silicone to be processed is placed on the cutting table 3. The control system 13 is turned on, and the laser cutting parameters, such as laser power and cutting speed, are set. The first motor 12 is started, driving the bidirectional screw 8 to rotate. The rotation of the bidirectional screw 8 causes the two moving seats 9 to move towards the center, thereby driving the L-shaped rod 10 to move linearly on the cutting table 3. The two sets of L-shaped rods 10 drive the two sets of fixing blocks 11 to clamp the thermally conductive silicone, ensuring that it will not move during processing. The position of the laser cutting head 2 is adjusted by the adjusting device, and then the laser cutting head 2 is started to cut according to the preset path of the control system 13. At the same time, the circulation pump 6 is started, causing the coolant in the circulation pipe 5 to flow. After being cooled by the refrigeration unit 7, the coolant flows into the refrigeration unit 7. The circulation pipe 5 inside the cutting table 3 removes the heat generated during the cutting process, preventing the thermally conductive silicone from overheating and deforming. The coolant then flows back to the refrigeration unit 7 (which includes a compressor, condenser, expansion valve, and evaporator. The refrigeration principle of the refrigeration unit 7 is to absorb and release heat through the circulation and state change of the refrigerant (from gaseous to liquid and back to gaseous), thereby achieving a cooling effect. The refrigeration unit 7 is a well-known technology and will not be described in detail here). After completing one cycle, the laser cutting head 2 can achieve micron-level cutting precision, ensuring that the edges of the thermally conductive silicone are smooth and burr-free, improving product quality. The cooling device can effectively remove the heat generated during the cutting process, preventing the thermally conductive silicone from deforming due to high temperature, and ensuring cutting quality and material performance.

[0026] In actual use, the position of the laser cutting stage 3 is further adjusted. In this embodiment, the adjustment device includes a second motor 14, a turntable 15, a mounting frame 16, a threaded rod 17, a slider 18, and a third motor 19. The second motor 14 is installed at the top of the support frame 4. The output end of the second motor 14 passes through the top wall of the support frame 4 and is installed on the turntable 15. The mounting frame 16 is horizontally installed on the bottom wall of the turntable 15. The threaded rod 17 is rotatably installed inside the mounting frame 16. One end of the threaded rod 17 passes through the side wall of the mounting frame 16 and is installed on the third motor 19. The slider 18 is threadedly installed on the threaded rod 17, and the bottom wall of the slider 18 is fixedly installed with... The laser cutting head 2 is activated by the control system 13. The output shaft of the third motor 19 rotates, driving the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the slider 18 to move left and right along the threaded rod 17, thereby adjusting the horizontal position of the laser cutting head 2. The second motor 14 is activated, and the output shaft of the second motor 14 rotates, driving the turntable 15 to rotate. The rotation of the turntable 15 causes the mounting frame 16 and its internal threaded rod 17 and slider 18 to move horizontally together, thereby adjusting the rotation of the laser cutting head 2. The cutting path, such as a straight line, curve, or circle, is preset on the control panel 22. The combined use of the first motor 12 and the second motor 14 can generate corresponding motion commands to meet the processing needs of thermally conductive silicone of different shapes.

[0027] Preferably, in this embodiment, the mounting frame 16 is U-shaped. Compared with other shapes, the U-shaped structure has stronger rigidity and can better resist external impacts and vibrations, ensuring the stability of the laser cutting head 2 during high-speed movement.

[0028] Preferably, in this embodiment, the four corners of the bottom of the processing table 1 are equipped with support legs 20. The four support legs 20 are evenly distributed at the four corners of the processing table 1, which ensures the stability of the processing table 1 when it is placed and avoids tilting or shaking caused by unstable center of gravity.

[0029] Preferably, in this embodiment, the support frame 4 is an L-shaped design. The L-shaped structure can be arranged more compactly above the processing table 1, saving space and making the whole device more compact and lightweight.

[0030] Preferably, in this embodiment, the first motor 12, the second motor 14, and the third motor 19 are all servo motors. Servo motors can control position, speed, and torque with high precision. Servo motors adopt closed-loop control, which has good stability and can avoid problems such as stalling and vibration, thereby improving the stability and accuracy of the operation of the first motor 12, the second motor 14, and the third motor 19.

[0031] Preferably, in this embodiment, a torque sensor 21 is installed on the side wall of the fixing block 11. The torque sensor 21 can monitor the clamping force applied by the fixing block 11 to the thermally conductive silicone in real time to ensure that the clamping force is within an appropriate range. This can prevent the thermally conductive silicone from deforming or being damaged due to excessive clamping force, and also prevent the thermally conductive silicone from moving during processing due to insufficient clamping force. Through the feedback of the torque sensor 21, the control system 13 can dynamically adjust the clamping force according to the actual situation to ensure that the best fixing effect can be achieved on thermally conductive silicone of different thicknesses and hardnesses.

[0032] Preferably, in this embodiment, the control system 13 is equipped with a control panel 22. The control panel 22 provides an intuitive graphical user interface (GUI). Operators can easily set and adjust various parameters through a touch screen or buttons without complicated operation steps. The control panel 22 can display the current working status, such as the position of the laser cutting head 2, the operation of the cooling system, clamping force, etc., so that operators can monitor the operating status of the equipment in real time.
