However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a heat dissipation paste coating mechanism with controllable coating thickness, including a mounting frame 1. The upper surface of the mounting frame 1 is fixedly installed with a mounting rod 2 for installing the top plate 3. The top of the mounting rod 2 is fixedly installed with a top plate 3, which can install the position of the mold 4. The surface of the top plate 3 is slidably connected with a mold 4, which can adapt to different workpieces. The upper surface of the top plate 3 is fixedly installed with a slide rail 5 to make the movement of the slide bar 6 smoother. The inside of the slide rail 5 is slidably connected with a slide bar 6, which is convenient for driving the squeegee 7 to move. Both sides of the slide bar 6 are fixedly installed with a squeegee 7 to scrape off the excess heat dissipation paste. The surface of the mounting frame 1 is rotatably connected with a lead screw 9 to make the lifting frame 10 lift smoothly through the rotation of the lead screw 9. The surface of the lead screw 9 is threadedly connected with a lifting frame 10, which is convenient for driving the workpiece to lift and move. The bottom end of the lead screw 9 is fixedly installed with a bevel gear B22, which can mesh with the bevel gear A14. The surface of the mounting frame 1 is fixedly installed with a guide rod 11 to make the lifting of the lifting frame 10 more stable. The side of the mounting frame 1 is fixedly installed with a mounting block 12 for installing the rotating rod 13. The inside of the mounting block 12 is rotatably connected with a rotating rod 13, which is convenient for driving the bevel gear B22 to rotate. One end of the rotating rod 13 is fixedly installed with a bevel gear A14, and the other end of the rotating rod 13 is fixedly installed with a turning head 15, which is convenient for rotating the rotating rod 13. The surface of the lifting frame 10 is provided with a suction cup 16 to adsorb and fix the workpiece. The side of the lifting frame 1 is fixedly installed with an air extraction pump 17 to extract the air inside the suction cup 16. The slide bar 6 and the squeegee 7 are slidably connected with the mold 4. The upper surface of the slide bar 6 is fixedly installed with a handle 8. Through the handle 8 on the slide bar 6, it is convenient to pull the slide bar 6, so that the squeegee 7 scrapes off the excess heat dissipation paste on the mold 4. The lifting frame 10 is slidably connected with the guide rod 11, and the bevel gear B22 is rotatably connected with the mounting frame 1. Through the guide rod 11, the lifting frame 10 can move up and down more stably, avoiding the lifting frame 10 rotating along with the rotation of the lead screw 9. The bevel gear A14 and the bevel gear B22 are meshed with each other. Through the meshing of the bevel gear A14 and the bevel gear B22, the rotation of the turntable can automatically drive the lead screw 9 to rotate. The suction cup 16 is communicated with the air extraction pump 17, and the air can be sucked out smoothly. The workpiece is positioned through the suction cup 16.

[0023] Embodiment 2

[0024] Please refer to Figures 1-4, a connecting rod 18 is slidably connected inside the top plate 3, enabling the mold 4 to be clamped. One end of the connecting rod 18 is fixedly installed with a pull head 19, facilitating the pulling of the connecting rod 18 and the positioning rod 21. A tension spring 20 is fixedly installed on the side of the pull head 19, enabling the connecting rod 18 and the positioning rod 21 to automatically return to their original positions. A positioning rod 21 is fixedly installed on the side of the pull head 19, enabling the mold 4 to be positioned and fixed, strengthening the fixation of the mold 4. The connecting rod 18 and the positioning rod 21 are slidably connected to the mold 4. One end of the tension spring 20 is fixedly connected to the top plate 3, enabling the connecting rod 18 and the positioning rod 21 to slide from inside the top plate 3 to inside the mold 4.

[0025] Working principle: First, place the workpiece to be coated on the suction cup 16. Through simple pressing and the extraction of air inside the suction cup 16 by the air pump 17, the workpiece can be sucked and fixed by the suction cup 16. Then, place the corresponding suitable mold 4 in alignment with the position of the top plate 3. When the mold 4 moves to the appropriate position, the tension spring 20 can drive the connecting rod 18 and the positioning rod 21 to move, enabling the connecting rod 18 and the positioning rod 21 to slide from inside the top plate 3 to inside the mold 4, thereby clamping and fixing the mold 4. Then, grasp the rotating head 15 and rotate it, causing the rotating head 15 to drive the bevel gear A 14 to rotate. When the bevel gear A 14 rotates, it can drive the meshing bevel gear B 22 to rotate, enabling the lead screw 9 to rotate smoothly on the surface of the mounting frame 1. When the lead screw 9 rotates, it can drive the lifting frame 10 to move up and down. At the same time, the lifting frame 10 slides on the surface of the guide rod 11, thus maintaining the stability of the lifting. The lifting frame 10 drives the workpiece to move to the position of the mold 4 on the top plate 3, thereby moving the workpiece into the mold 4. Then, apply heat dissipation paste to the workpiece, and then grasp the handle 8 and pull it, causing the handle 8 to drive the sliding rod 6 to slide inside the top plate 3 and the slide rail 5. When the sliding rod 6 slides, it can drive the scraper 7 to move, controlling the thickness of the heat dissipation paste on the workpiece according to the position of the workpiece inside the mold 4.

[0026] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
