Through the groove, the sliding frame 211 can also drive the first roller 213 to move when sliding inside, thereby increasing the range of movement of the first spring 212 and improving the stability of the device.
[0023] See also Figure 1-Figure 3In this embodiment, the rear end of the vacuum shell 1 is fixedly connected to a motor 21, and the output shaft of the motor 21 is rotatably connected to the interior of the vacuum shell 1. The outer end of the output shaft of the motor 21 is fixedly connected to a winding roller 22, and the interior of the vacuum shell 1 is rotatably connected to a winding roller 23. An ultra-thin electromagnetic shielding film body 24 is arranged between the winding roller 22 and the winding roller 23. The interior of the vacuum shell 1 is rotatably connected to a rotating roller 25. There are several rotating rollers 25, and the several rotating rollers 25 are rotatably connected to the interior of the vacuum shell 1, and the several rotating rollers 25 are in contact with the ultra-thin electromagnetic shielding film body 24. A magnetron sputtering device 26 is arranged inside the vacuum shell 1. The magnetron sputtering device is a device for physical vapor deposition (PVD), mainly used for thin film preparation. Its working principle is to introduce a magnetic field in a vacuum environment and use the magnetic field to confine charged particles to increase the plasma density, thereby increasing the sputtering rate. Specifically, electrons collide with argon atoms under the action of the electric field to generate argon ions and new electrons. The argon ions bombard the target material under the action of the electric field, causing the target atoms to sputter. The film is ejected and deposited on the substrate to form a thin film. The interior of the vacuum shell 1 is connected to a cooling roller 27 for rotation. A heater 28 is provided inside the vacuum shell 1. An ion source 29 is provided inside the vacuum shell 1. It is fixed to the interior of the vacuum shell 1 through a first fixed frame 210, so that it slides inside the first fixed frame 210 through a sliding frame 211. The first spring 212 is reset by elastic force, so that it rotates inside the sliding frame 211 through the first roller 213. When the ultra-thin electromagnetic shielding film body 24 is transported, it contacts it and limits the two sides of the ultra-thin electromagnetic shielding film body 24 to prevent the ultra-thin electromagnetic shielding film body 24 from shifting, thereby improving the practicality of the device and the stability of the ultra-thin electromagnetic shielding film preparation device.

Through contact, it guides the ultra-thin electromagnetic shielding film body 24 to prevent the position of the ultra-thin electromagnetic shielding film body 24 from shifting.
[0024] See also Figure 4In this embodiment, the stabilizing component includes a second fixed frame 35, which is fixedly connected to the inside of the vacuum shell 1. The inside of the second fixed frame 35 is slidably connected to a slider 31, the bottom of the slider 31 is fixedly connected to a bracket 32, and the inside of the bracket 32 is rotatably connected to a second roller 33.

[0025] During operation, the ultra-thin electromagnetic shielding film body 24 inside the unwinding roller 23 is transported by starting the motor 21, and is wound by the winding roller 22. The electromagnetic shielding film is preheated by the heater 28, which can degas and clean the surface of the electromagnetic shielding film in combination with the ion source 29, so that the obtained film layer composition can be purer. On the other hand, the electromagnetic shielding film with a higher temperature can increase the diffusion rate of the film material molecules reaching the surface of the electromagnetic shielding film, making the film layer more uniform, and the bonding force between the film layer and the electromagnetic shielding film is higher. There are several rotating rollers 25, and several rotating rollers 25 are rotatably connected to the inside of the vacuum shell 1, and several rotating rollers 25 are in contact with the ultra-thin electromagnetic shielding film body 24. There are two cooling rollers 27, and six magnetron sputtering devices 26 are arranged outside the two cooling rollers 27, which are fixed to the inside of the vacuum shell 1 by the first fixed frame 210. The first spring 212 is reset by elastic force so that the first roller 213 is rotated inside the sliding frame 211 and contacts the ultra-thin electromagnetic shielding film body 24 when the ultra-thin electromagnetic shielding film body 24 is transported, and the two sides of the ultra-thin electromagnetic shielding film body 24 are limited to prevent the ultra-thin electromagnetic shielding film body 24 from being offset, thereby improving the practicality of the device and the stability of the ultra-thin electromagnetic shielding film preparation device. The slider 31 slides inside the second fixed frame 35, and the second spring 34 resets it, and the second roller 33 rotating inside the bracket 32 contacts the ultra-thin electromagnetic shielding film body 24, and is reset by the elasticity of the second spring 34, thereby improving the stability of the ultra-thin electromagnetic shielding film body 24 and the winding effect of the ultra-thin electromagnetic shielding film body 24, thereby improving the practicality of the device.
[0026] Through the above steps, the sliding frame 211 slides inside the first fixed frame 210, and the first spring 212 is reset by elastic force, so that it rotates inside the sliding frame 211 through the first roller 213, and contacts the ultra-thin electromagnetic shielding film body 24 when it is transported, thereby limiting the two sides of the ultra-thin electromagnetic shielding film body 24 to prevent the ultra-thin electromagnetic shielding film body 24 from shifting, so as to solve the problem that the ultra-thin electromagnetic shielding film cannot be limited, causing its position to shift and thus causing creases.
