The modular design facilitates equipment maintenance and upgrades, improving practicality. The distillation assembly includes a distiller 6, which is mounted on the center of the bottom surface inside the housing 2. The distiller 6 consists of a heating crucible and an electron gun. The distiller 6 is connected to the coating solution and a power source. A vacuum pipe 7 is provided on one side of the distiller 6. The vacuum pipe 7 penetrates the bottom surface of the equipment housing 2 and is connected to a vacuum pump. The cooperation between the distiller 6 and the vacuum pipe 7 facilitates the creation of a vacuum environment and the evaporation and emission of the coating solution, thus improving practicality. The shutter assembly includes a first motor 8, which is mounted and fixed on one side of the bottom surface of the equipment housing 2. The top surface of the first motor 8 penetrates the equipment housing 2 and is connected to a rotating shaft 9. A baffle 10 is fixed to the top surface of the rotating shaft 9. The cooperation between the first motor 8 and the baffle 10 facilitates the control of the emission time of the coating solution, thus improving practicality.

[0024] In this utility model, the clamping mechanism includes a second motor 11, which is fixedly mounted on the center of the top surface of the equipment housing 2. The bottom surface of the second motor 11 penetrates the equipment housing 2 and is fixedly connected to a snap-fit ​​seat 12. A snap-fit ​​plate 13 is snapped onto the bottom surface of the snap-fit ​​seat 12. A clamping box 14 is fixedly connected to the bottom surface of the snap-fit ​​plate 13. A support frame 15 is fixedly connected inside the clamping box 14. A flipping component is provided on the support frame 15. Through the cooperation of the second motor 11, the snap-fit ​​seat 12, and the snap-fit ​​plate 13, the clamping mechanism is easy to disassemble and install, and the practicality is improved. The flipping component includes a third motor 16, which is fixedly mounted on the inner side of the clamping box 14. The third motor 16 is connected to a rotating rod 17, which rotates at equal angles around the center of the support frame 15. The rotation rods 17 are rotatably connected by connecting rods 18 on the outer ring of the support frame 15. The inner side of the rotation rods 17 is connected to the clamping assembly by the connecting shaft 19. Through the cooperation of the third motor 16, the rotation rods 17 and the connecting rods 18, it is easy to automatically drive each rotation rod 17 to rotate synchronously, which improves practicality. The clamping assembly includes a clamping plate 20. The bottom surface of the clamping plate 20 has a threaded hole. A threaded rod 22 is fitted in the threaded hole. The top of the threaded rod 22 is rotatably connected to a washer. A micro motor 21 is installed on the top surface of the clamping plate 20. The lower end of the micro motor 21 passes through the clamping plate 20 and is fixed to a washer. A filter 23 is clamped between the washer. Through the cooperation of the threaded rod 22 and the micro motor 21, it is easy to clamp and rotate the filter 23, which improves practicality.

[0025] Working principle: When using this utility model, first, power is supplied to all electrical equipment. Then, the cleaned filter 23 is horizontally inserted into the clamping plate 20 from below the clamping box 14. At this time, the filter 23 is coaxial with the clamping plate 20. Then, the threaded rod 22 is rotated, which will drive the shim to move upward, thereby clamping the filter 23. After all the clamping plates 20 are filled with filter 23, the spring lock 5 is opened and the equipment door 3 is opened. Then, the clamping box 14 is sent into the equipment housing 2. Then, the top surface of the snap-fit ​​plate 13 abuts against the bottom surface of the snap-fit ​​seat 12. Then, the clamping box 14 is rotated. At this time, the snap-fit ​​plate 12 and the snap-fit ​​seat 13 are connected and fixed. Then, the equipment door 3 is closed and the spring lock 5 is locked. After the personnel leave the equipment, the vacuum pump is started and the equipment is evacuated through the suction pipe 7. The air inside the housing 2 is brought to a vacuum state, and then the distiller 6 is driven. The distiller 6 first draws the coating solution into the crucible, then heats the coating solution, and at the same time drives the electron gun to move the evaporated coating solution in the direction of the electron gun. Meanwhile, the first motor 8 drives the baffle 10 to intermittently block the scattering of the coating solution. While the distiller 6 is working, the second motor 11 drives the clamping box 14 to rotate, and at the same time the micro motor 21 drives the filter 23 to rotate, so that the edge of the filter 23 is evenly covered with the coating solution to form a transparent film. After one side of the film is coated, the third motor 16 is started to rotate the rotating rod 17. The rotation of the rotating rod 17 will drive the connecting rod 18 to rotate, thereby driving all the connecting shafts 19 to rotate synchronously, realizing the flipping of the clamping plate 20, so that the film can be coated on both sides.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
