[0026] Figure 6 This is a schematic diagram of the membrane module structure of this utility model. Figure 2 . Detailed Implementation

[0027] This application provides a screen protector applicator for foldable phones. The applicator uses a rolling pressing method, which ensures even pressure and reduces air bubble formation. This solves the problem in existing technologies that use a scraper mold, where uneven application and air bubbles are caused by variations in individual grip, force, and board tilt. Additionally, a handle film is included. After the positioning film is fixed, the release film can be peeled off using the handle film, reducing dust and other contaminants on the UTG film and preventing debris from getting between the UTG film and the phone screen after application. This addresses the issue in existing technologies where the release film needs to be peeled off first before fixing the film assembly, which can lead to dust and other contaminants on the UTG film during the fixing process, resulting in foreign objects between the UTG film and the phone screen after application.

[0028] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case:

[0029] Depend on Figure 1 — Figure 6 As can be seen, this application includes a base 1, which has a receiving cavity 110 for fixing the mobile phone. It also includes a film assembly 2, and the base further includes a positioning component for positioning the film assembly 2, suspending it above the mobile phone. A film presser 3 is also included, which has a rolling part 310 that rolls against the film assembly 2, causing the film assembly 2 to adhere to the mobile phone screen. In this embodiment, the rolling contact between the film presser 3 and the film assembly 2 ensures uniform force on the upper surface of the film assembly 2 during use, effectively reducing air bubbles, especially at the creases of the mobile phone screen.

[0030] Based on the above embodiments, preferably, the film presser 3 includes a crossbeam 320, with downwardly extending beam ends 321 at both ends of the crossbeam 320. The rolling part 310 is connected to the beam ends 321, and a handle 330 is also provided on the crossbeam 320. This embodiment provides a specific structure of the film presser 3. It should be understood that this embodiment provides only one possible implementation, and all film pressers 3 using the rolling film pressing method should be within the protection scope of this application. In use, the operator holds the handle 330 and applies force to make the rolling part 310 roll across the upper surface of the positioning film of the film assembly 2, so that the UTG film is subjected to force and adheres to the mobile phone screen.

[0031] Based on the above embodiments, preferably, the rolling part 310 includes a roller shaft 311 and a roller body 312. The two ends of the roller shaft 311 are fixedly connected to the beam end 321, and the roller body 312 is rotatably connected to the roller shaft 311. In this embodiment, the roller body 312 and the roller shaft 311 can be directly sleeved together, or bearings or other components can be provided between them to enhance the smoothness of the roller body 312's rotation. The rolling part 310 has a simple structure and low manufacturing cost, but effectively enhances the film application effect.

[0032] Based on the above embodiments, preferably, the accommodating cavity 110 of the base 1 is provided with limiting portions 120 on both the left and right sides, and the limiting portions 120 limit the movement direction of the film presser 3. In this embodiment, the limiting portions 120 are elongated protrusions. When the film presser 3 is working, the two elongated protrusions on both sides of the accommodating cavity 110 limit the beam end 321, ensuring the movement direction of the film presser 3 and preventing deviation. An elongated groove 130 is provided inside the limiting portion, which accommodates the beam end 321, allowing the rolling part 310 of the film presser 3 to fully fit with the film assembly when working, ensuring the film application effect.

[0033] Based on the above embodiments, preferably, the positioning component includes a first positioning part 140 and a second positioning part 150. The first positioning part 140 is disposed on the upper side of the receiving cavity 110, and the second positioning part 150 is disposed on the lower side of the receiving cavity 110. The positioning height of the first positioning part 140 is greater than the positioning height of the second positioning part 150, so that the fixed film assembly 2 is close to the mobile phone screen in the direction near the second positioning part 150 and away from the mobile phone screen in the direction near the first positioning part 140, and is suspended above the mobile phone in an inclined state. By setting the first positioning part 140 and the second positioning part 150 on the upper and lower sides of the receiving cavity 110 to position the film assembly 2, and the positioned film assembly 2 is suspended above the mobile phone in an inclined state, when using the film presser 3, the film presser 3 moves from the direction of lower height of the film assembly 2 to the direction of higher height, which facilitates the film pressing operation.

[0034] Based on the above embodiments, preferably, the first positioning part 140 is inserted into the base 1, and the second positioning part 150 is integrally formed with the base 1. Because the height of the first positioning part 140 is relatively large, it would be inconvenient to transport and store it if it were integrally formed with the base 1. By using an insertion connection, the first positioning part 140 can be removed and placed into the receiving cavity 110 during transportation or storage, saving space. The overall height of the second positioning part 150 is similar to that of the base 1, and the integral formation can reduce production costs.

[0035] The first positioning part 140 includes at least two positioning posts 141 and a connector 142. The connector 142 connects the positioning posts 141. The connector 142 enhances the strength between the positioning posts 141, preventing deformation, and also serves as a limit, restricting the height of the membrane assembly 2 on the positioning posts 141. The second positioning part 150 includes two or more positioning protrusions 151. The two outermost positioning protrusions 151 have different shapes; in this embodiment, one side is square and the other is circular. Similarly, the positioning hole 211 on the membrane assembly 2 corresponding to the second positioning part 150 also has one square and one circular side. The different shapes of the positioning protrusions 151 and positioning holes 211 prevent the membrane assembly 2 from being reversed.

[0036] Based on the above embodiments, preferably, the bottom of the receiving cavity 110 is provided with a plurality of support blocks 111, which support the mobile phone. The edge of the receiving cavity 110 is provided with a plurality of grooves 112 communicating with the receiving cavity 110. Since the mobile phone has components such as a camera, and the camera protrudes beyond the height of the mobile phone, the support blocks 111 provide space for accommodating these components. The grooves 112 facilitate the removal of the mobile phone after applying a screen protector.

[0037] Based on the above embodiments, preferably, the film assembly 2 includes a positioning film 210, a UTG film 220, an AB adhesive layer 230, and a release film 240 stacked sequentially. The positioning film 210 has positioning holes 211 corresponding to the positioning assembly, and is connected to the positioning assembly of the base 1 through the positioning holes 211 on the positioning film 210. The positioning hole 211 corresponding to the first positioning part 140 includes a main hole 211a and a secondary hole 211b. An easy-tear line or a long strip hole is provided between the main hole 211a and the secondary hole 211b. If a long strip hole is provided, its width is smaller than the diameter of the main hole 211a. In use, the main hole 211a is first fitted onto the positioning post 141. As the molding press 3 moves, the film assembly 2 tends to move downwards to fit against the mobile phone screen. At this time, the positioning post 141 slides from the main hole 211a through the easy-tear line or long strip hole into the secondary hole 211b. Since the width of the tear line or the long hole is smaller than the diameter of the main hole 211a, the positioning post 141 is stably located in the main hole 211a when no external force is applied, and the positioning effect is stable. After the pressure is applied by the film presser 3, the positioning post 141 can smoothly slide into the secondary hole 211b, preventing the film assembly 2 from being deformed or damaged by force, which would affect the film application effect.

[0038] Based on the above embodiments, preferably, the release film 240 is also connected to the handle film 250. The release film 240 and the handle film 250 are connected by an adhesive patch or other means, so that when the handle film 250 is pulled, the release film 240 and the handle film 250 move accordingly. Specifically, a pull hole 160 is provided on the base 1 between the second positioning part 150 and the receiving cavity 110, and a notch 170 is provided on the edge of the base 1. When fixing the positioning film 210, the handle film 250 is passed through the pull hole 160 and then out through the notch 170. After the positioning film 210 is fixed, pulling the handle film 250 causes the release film 240 to be torn off under the pull of the handle film 250, and then sequentially passed through the pull hole 160 and the notch 170 for removal. The release film 240 is removed before fixing the positioning film 210 to prevent contamination of the UTG film.
