A dust-proof and scratch-proof release film 5 is connected below the silk-screen frame explosion-proof film 2. The thickness of the dust-proof and scratch-proof release film 5 is set to 20um-200um. The dust-proof and scratch-proof release film 5 of the mobile phone is also called a peeling film, an isolation film, etc., which is used to protect one side of the tempered film of the mobile phone from damage before lamination. When in use, just tear it off from one side of the tempered film. Due to the use function and status of the dust-proof and scratch-proof release film 5, product information such as product trademark Logo, QR code, model, and code can be selectively drawn on it.

[0021] A mobile phone screen protection film provided in the present application is improved and innovated on the basis of traditional mobile phone tempered films. It also belongs to the category of mobile phone tempered films in general, and is specifically designed to protect the screens of curved screen mobile phones. The above-mentioned middle glass layer 1, silk-screen frame explosion-proof film 2 and dust-proof and scratch-resistant release film 5 constitute the main body of the mobile phone tempered protective film, wherein the glass layer 1 is made of medium aluminum / high aluminum precision glass material, and the method for protecting the mobile phone screen with the film adopts the method of tempered glass + UV glue bonding, which is simple, convenient, easy to use and operate successfully. The unused tempered film is protected by the dust-proof and scratch-resistant release film 5, which is torn off when in use. After the mobile phone screen is wiped clean, the tempered glass with the glass layer 1 and the silk-screen frame explosion-proof film 2 as the main body after the dust-proof and scratch-resistant release film 5 is removed can be bonded to the mobile phone screen. Before the tempered glass is bonded to the mobile phone screen by UV glue, that is, before the UV glue is dripped on the mobile phone screen, the mobile phone screen needs to be wiped clean with a cloth to prevent the dust remaining on the mobile phone screen from affecting the normal use of the mobile phone after the film is bonded.

[0022] Embodiment 2

[0023] Combined with Figure 1-2 A water-blocking rubber strip 3 is commonly connected between the silk-screen frame explosion-proof film 2 and the dust-proof and scratch-proof release film 5. The water-blocking rubber strip 3 is also called a water-blocking material device. The water-blocking rubber strip 3 is a transparent material. The water-blocking rubber strip 3 has a sticky setting on the side close to the silk-screen frame explosion-proof film 2. The thickness of the water-blocking rubber strip 3 is 0.05mm to 0.3mm, and the width of the water-blocking rubber strip 3 is 0.03mm to 2mm. The exhaust channel 4 is located at the corner of the water-blocking rubber strip 3. The exhaust channel 4 is horn-shaped. The water-blocking rubber strip 3 passes through the air. The sticky side of the body is attached to the silk-screen frame explosion-proof film 2, and the non-sticky side covers the mobile phone screen, which prevents the UV glue from overflowing and seeping out. The water-blocking strip 3 is connected with a plurality of exhaust channels 4, which do not affect the appearance and are arranged at the four corners of the mobile phone screen. Each corner corresponds to an exhaust channel 4, which automatically discharges the air between the mobile phone screen and the tempered glass film. The exhaust channels 4 can be reasonably selected between 1 and 4 on the tempered film device according to the objective needs of use and production.

[0024] The air retained between the tempered glass film and the mobile phone screen in the attached state is automatically discharged through the four trumpet-shaped exhaust channels 4 on the tempered glass protective film. This process can also be assisted by simply pressing the mobile phone screen with your hand. The pressing operation will also promote the UV glue retained between the mobile phone screen and the tempered film to diffuse evenly toward the edge. During the diffusion process, the liquid UV glue will squeeze out the air in the bubbles, which is conducive to the discharge of the air. At this time, the water-blocking strip 3 arranged between the edges of the silk-screen frame explosion-proof film 2 and the mobile phone screen can effectively intercept the overflowing UV glue, thereby preventing it from flowing outside the screen area and protecting the buttons, charging port, SIM card port, and audio / video port around the mobile phone. The parts such as the barrel hole, the gaps on the sides and back of the mobile phone and the special materials such as the plain leather are affected to prevent the flow of water into them and cause blockage and erosion. The black frame line 6 on the edge of the silk-screen frame explosion-proof film 2 is used to block the stacked UV glue from the water-blocking strip 3 to cover it, so that no excess UV glue accumulation can be seen on the edge of the mobile phone screen, preventing the UV glue accumulation from affecting the viewing and appearance of the mobile phone screen after drying. The drying and curing of the UV glue is achieved by using a baking lamp. When using the baking lamp, place the baking lamp above the mobile phone screen after the film is applied. When using the baking lamp to provide temperature rise to cure the UV glue, you can choose to move the baking lamp slowly and evenly above the mobile phone screen, so that the UV glue in each area of ​​the mobile phone screen is heated evenly, thereby accelerating the curing process.

[0025] When the utility model is implemented, the present application provides a protective film structure for a mobile phone screen, and an installation method for using the protective film to stick on the mobile phone screen. The main purpose is to protect the screen of a curved screen mobile phone. When using the mobile phone protective film device, the following steps should be adopted to achieve a more perfect fitting effect. First, use a cloth to wipe the mobile phone screen. Generally, a microfiber cloth containing an appropriate amount of alcohol is used. This is to avoid the dust attached to the mobile phone screen from having an adverse effect on the use of the mobile phone screen after the film is applied. On the cleaned mobile phone screen, try to be in the center position and drop an appropriate amount of UV glue. Before this, the size of the selected mobile phone protective film should be consistent with the mobile phone model and screen size. The dust-proof and scratch-proof release film 5 on the mobile phone protective film is torn off, and the exposed side is carefully and completely attached to the mobile phone screen. At this time, the air between the mobile phone screen and the tempered glass will be automatically emptied through the trumpet-shaped exhaust channel 4 on the protective film. The exhaust channel 4 can also be regarded as an exhaust hole to avoid the generation of bubbles. The UV glue between the screen and the tempered glass protective film will also be correspondingly The UV glue will automatically spread and overflow evenly around the tempered glass protective film, but the single-sided water-blocking adhesive strip 3 material at the bottom layer of the tempered glass protective film will automatically intercept the excess UV glue at the edges around the screen. The UV glue will be evenly locked in the tempered glass protective film and will not overflow and seep out of the tempered glass protective film, thereby protecting the buttons, charging port, SIM card port, ear / microphone holes and other parts around the phone, the gaps on the sides and back of the phone, and special materials such as plain leather, which will not be blocked or eroded by the overflowing UV glue. When the UV glue is discharged to the tempered glass protective film, the UV glue will not be blocked or eroded by the overflowing UV glue. After the edge of the water-blocking tape 3 material around the film is reached, it is covered by the silk-screen black frame line 6 of the explosion-proof film of the tempered glass protective film, so that no excess UV glue accumulation can be seen on the edge of the mobile phone screen. The above-mentioned process of air and UV glue being discharged and diffused can be assisted by pressing the mobile phone screen appropriately with the hand. Finally, a UV baking lamp is placed above the mobile phone screen to irradiate the UV glue in the tempered protective film to be cured. The film installation method is simple and convenient, and is suitable for curved screen mobile phones. It avoids the formation of bubbles and the like, and ensures the texture of the mobile phone after the film is applied.

[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
