[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model embodiment provides a film application device, see [link to relevant documentation] Figure 1 and Figure 5 , Figure 1 This is a schematic diagram of the film application device, which includes: a base plate 1, positioning posts 3, and limiting components;

[0040] A limiting component is provided on the upper end face of the base plate 1 to limit the lateral and longitudinal movement of the mobile phone 13 along the base plate 1;

[0041] The first side of the limiting member has a first clearance opening 7 for the first release paper to pass through, and the second side of the limiting member has a second clearance opening 8 for the positioning ear to pass through;

[0042] The positioning post 3 is disposed on the upper end face of the base plate 1 and located on the second side of the limiting member. The positioning post 3 is used to cooperate with the positioning hole of the second release paper 142.

[0043] It should be noted that the film application device of this application can apply film to terminal devices with screens, such as mobile phones 13. Therefore, the embodiments of this application all use mobile phones 13 as an example for illustration. The film application device of this application is mainly used for the construction of the film assembly 14 composed of pull strip 141, protective film, first release paper and second release paper 142. The first release paper is pasted on the upper end surface of the protective film, and the second release paper 142 is pasted on the lower end surface of the protective film. The first side of the second release paper 142 is provided with a positioning ear protruding from the first side of the protective film. The positioning ear has a positioning hole. The pull strip 141 is disposed on the upper end surface of the first release paper, and one side of the pull strip 141 is connected to the upper end surface of the first release paper. The first release paper is connected to one side, and the pull end of the pull strip 141 protrudes from the second side of the protective film. When it is necessary to apply a screen protector to the mobile phone 13, the mobile phone 13 is placed on the base plate 1, and the screen of the mobile phone 13 is aligned with the pull strip 141. Then, the back of the mobile phone 13 is pressed, and the first release paper is peeled off from the adhesive surface of the protective film through the pull end of the pull strip 141 and pulled out from the first relief opening 7. At this time, the protective film adheres to the screen of the mobile phone 13 under the pressure. Since the first release paper is gradually peeled off from one side of the protective film, the adhesive of the protective film also gradually adheres to the screen of the mobile phone 13, and air bubbles are avoided between the protective film and the screen of the mobile phone 13 under the pressure.

[0044] It should also be noted that when the pull strip 141 is pulled out from the first clearance opening 7, the pull strip 141 and the first release paper can remove dust from the screen of the mobile phone 13, ensuring better adhesion between the protective film and the screen of the mobile phone 13, and preventing dust from affecting the user's screen viewing experience.

[0045] It should be noted that this application is not only applicable to mobile phone 13, but also to other terminal devices with screens for applying screen protectors.

[0046] In this embodiment of the invention, a limiting member for restricting the lateral and longitudinal movement of the mobile phone 13 along the base plate 1 is disposed on the upper end surface of the base plate 1. A first clearance opening 7 for the first release paper to pass through is provided on the first side of the limiting member, and a second clearance opening 8 for the positioning ear to pass through is provided on the second side of the limiting member. A positioning post 3 is disposed on the upper end surface of the base plate 1 and located on the second side of the limiting member. The positioning post 3 is used to cooperate with the positioning hole of the second release paper 142. With the film-applying device disclosed above, the mobile phone 13 can be fixed by the limiting member, and the protective film can be positioned by the positioning post 3. After the pull strip 141 is pulled out, the protective film can be accurately applied to the screen of the mobile phone 13. When applying the film, the mobile phone 13 is pressed, so that the protective film gradually adheres to the screen of the mobile phone 13 under the action of pressure, effectively reducing the generation of air bubbles between the protective film and the screen of the mobile phone 13.

[0047] Specifically, the limiting components include: the first limiting component 4 and the second limiting component 5;

[0048] The first limiting component 4 and the second limiting component 5 form a fixed position for limiting the lateral and longitudinal movement of the mobile phone 13 along the base plate 1;

[0049] The first limiting component 4 has a first clearance opening 7, and the second limiting component 5 has a second clearance opening 8.

[0050] It should be noted that the limiting component can be a fixed position formed by the first limiting component 4 and the second limiting component 5 to limit the lateral and longitudinal movement of the mobile phone 13 along the base plate 1, or it can be an integral frame structure. Those skilled in the art can choose according to their needs.

[0051] Specifically, the first limiting component 4 is the same as the second limiting component 5. The first limiting component 4 includes: a first limiting member 41 and a second limiting member 42.

[0052] Both the first limiting member 41 and the second limiting member 42 are L-shaped components.

[0053] It should be noted that the first limiting component 4 and the second limiting component 5 are set to be the same, and the first limiting component 4 is set to an L-shaped first limiting member 41 and second limiting member 42. Thus, the first limiting component 4 and the second limiting component 5 cooperate with each other to form a fixed position that restricts the lateral and longitudinal movement of the mobile phone 13 along the base plate 1.

[0054] It should also be noted that a second clearance opening 8 for the positioning ear to pass through can be formed between the first limiting member 41 and the second limiting member 42 of the first limiting component 4.

[0055] It is worth noting that the second limiting component 5 can be configured as two L-shaped limiting components with the same structure as the first limiting component 4, or it can be configured as a whole U-shaped limiting component. The first clearance opening 7 at its bottom can also limit the horizontal and vertical movement of the mobile phone 13 and allow the first release paper to pass through.

[0056] Furthermore, the film application device also includes: a boss 6 and an elastic support 2;

[0057] Multiple protrusions 6 are provided on the upper surface of the base plate 1 and along the edge of the fixing position. The multiple protrusions 6 are used to support the terminal equipment.

[0058] The elastic support 2 is disposed on the upper end surface of the base plate 1 and is located in the fixed position. The upper end surface of the elastic support 2 is higher than the upper end surface of the boss 6. The elastic support 2 is used to support the membrane assembly 14.

[0059] It should be noted that multiple protrusions 6 are set on the upper surface of the base plate 1 and along the edge of the fixed position. The multiple protrusions 6 are used to support the terminal device. An elastic support 2 is set on the upper surface of the base plate 1 and located within the fixed position. The upper surface of the elastic support 2 is higher than the upper surface of the protrusions 6. The elastic support 2 is used to support the film assembly 14. When it is necessary to apply a film to the mobile phone 13, the mobile phone 13 is placed in the fixed position and the screen of the mobile phone 13 is aligned with the pull strip 141. Then, the back of the mobile phone 13 is pressed, and the first release paper is peeled off from the adhesive surface of the protective film through the pull end of the pull strip 141 and pulled out from the first clearance opening 7. At this time, the protective film can always be in contact with the screen of the mobile phone 13 under the action of the elastic recovery force provided by the elastic support 2, which effectively reduces the generation of air bubbles between the screen of the mobile phone 13 and the protective film. Since the pull strip 141 is gradually pulled out, the elastic recovery force provided by the elastic support 2 is constant. Therefore, it can effectively reduce the generation of air bubbles between the protective film and the screen of the mobile phone 13.

[0060] It should also be noted that the first release paper is peeled off from the adhesive surface of the protective film by the pull-out end of the pull strip 141 and pulled out from the first clearance opening 7. At this time, the middle part of the protective film first contacts the screen of the mobile phone 13 under the elastic restoring force provided by the elastic support member 2, and then gradually spreads to the surroundings under the elastic restoring force provided by the elastic support member 2 to contact and adhere to the screen of the mobile phone 13, and vents air in all directions to avoid air bubbles between the protective film and the screen affecting the user's viewing experience.

[0061] Specifically, the elastic support 2 is a long strip structure;

[0062] The elastic support 2 is installed on the base plate 1 along the pull-out direction of the pull-out strip 141.

[0063] It should be noted that the elastic support 2 can be a long strip structure or a structure of other shapes, and those skilled in the art can choose according to their needs.

[0064] It is worth noting that the elastic support 2 can be disposed on the base plate 1 along the pull-out direction of the pull bar 141, or it can be disposed along other directions of the bottom. Those skilled in the art can choose according to their needs. However, in this application, it is preferred that the elastic support 2 be disposed on the base plate 1 along the pull-out direction of the pull bar 141.

[0065] Preferably, the base plate 1 has a mounting groove 1-1 for mounting the elastic support member 2.

[0066] It should be noted that by opening the mounting groove 1-1 for mounting the elastic support 2 in the base plate 1, the elastic support 2 can be prevented from shifting due to pressing the mobile phone 13 during the film application process, thereby ensuring the smooth application of the protective film.

[0067] Furthermore, the film application device also includes: a pressure plate 91 and a third limiting component 10;

[0068] The contact surface of the pressure plate 91 that contacts the back of the mobile phone 13 is provided with a plurality of first protrusions 92, wherein the plurality of first protrusions 92 are distributed on the first side and the second side of the pressure plate 91.

[0069] The first limiting component 4 and the third limiting component 10 are disposed on the first side of the base plate 1, the second limiting component 5 is disposed on the second side of the base plate 1, and the first limiting component 4 is located between the second limiting component 5 and the third limiting component 10.

[0070] The third limiting component 10 and the second limiting component 5 are used to cooperate with a plurality of first protrusions 92 to restrict the lateral and / or longitudinal movement of the pressure plate 91.

[0071] It should be noted that by setting a pressure plate 91 and a third limiting component 10, and setting multiple first protrusions 92 on the contact surface of the pressure plate 91 that contacts the back of the mobile phone 13, and distributing the multiple first protrusions 92 on the first and second sides of the pressure plate 91, the first limiting component 4 and the third limiting component 10 are set on the first side of the base plate 1, and the second limiting component 5 is set on the second side of the base plate 1, with the first limiting component 4 located between the second limiting component 5 and the third limiting component 10. The third limiting component 10 and the second limiting component 5 are used to cooperate with the multiple first protrusions 92 to restrict the lateral and / or longitudinal movement of the pressure plate 91. Thus, when the back of the mobile phone 13 is pressed by the pressure plate 91 during the screen protector application process, the back of the mobile phone 13 can be subjected to more even force, and with the third limiting component 10 and the second limiting component 5 cooperating with the multiple first protrusions 92, the lateral and / or longitudinal movement of the pressure plate 91 can be avoided.

[0072] It is worth noting that when the third limiting component 10 and the second limiting component 5 are engaged with the multiple first protrusions 92, they can be transported without deformation.

[0073] Specifically, the third limiting component 10 includes: a third limiting member and a fourth limiting member;

[0074] Both the third and fourth limiting components are L-shaped.

[0075] It should be noted that the third limiting component 10 is configured as a third limiting member and a fourth limiting member, and both the third limiting member and the fourth limiting member are L-shaped components. Thus, the third limiting component 10 and the second limiting component 5 cooperate to form a fixed position that restricts the lateral and longitudinal movement of the mobile phone 13 along the base plate 1.

[0076] It is worth noting that the third limiting component 10 can be configured to be an L-shaped component, as can the L-shaped third and fourth limiting components, or it can be configured as a single U-shaped limiting component.

[0077] Preferably, the positioning post 3 is located between the first limiting component 4 and the third limiting component 10.

[0078] Furthermore, the film application device also includes: a second protrusion 93 disposed in the middle of the pressure plate 91;

[0079] The second protrusion 93 is a ring structure.

[0080] It should be noted that by setting the second protrusion 93 in the middle of the pressure plate 91, after the pull strip 141 pulls the first release paper and the protective film apart, by pressing the second protrusion 93, the protective film first contacts the middle of the screen of the mobile phone 13, and gradually spreads outwards along the first contact position, so that the protective film gradually contacts the screen and vents air in all directions, avoiding the formation of air bubbles between the protective film and the screen that would affect the user's viewing experience.

[0081] It should also be noted that the second protrusion 93 can be a ring structure or a structure of other shapes, which can be selected by those skilled in the art according to their needs.

[0082] Furthermore, the film-applying device also includes a flexible connector 11 for connecting the pressure plate 91 and the base plate 1.

[0083] It should be noted that by setting up a flexible connector 11 for connecting the pressure plate 91 and the base plate 1, it is convenient for users to press the mobile phone 13 with the pressure plate 91 during the film application process.

[0084] Preferably, the flexible connector 11 is made of cardboard.

[0085] It should be noted that the flexible connector 11 can be made of cardboard or other materials, and those skilled in the art can choose according to their needs.

[0086] It is worth noting that when the flexible connector 11 is made of cardboard, one side of the cardboard is pasted to the lower end face of the base plate 1, and the other side is pasted to the pressing surface of the pressure plate 91.

[0087] Specifically, the positioning post 3 and the first clearance opening 7 are positioned opposite each other on both sides of the fixed position.

[0088] It should be noted that the positioning post 3 and the first clearance opening 7 are positioned opposite each other on both sides of the fixed position, or they can be positioned on adjacent sides of the fixed position. Those skilled in the art can choose according to their needs.

[0089] Preferably, the elastic support 2 is made of polyurethane foam.

[0090] It should be noted that the elastic support 2 can be made of polyurethane foam or other elastic materials that can produce elastic deformation when subjected to external force. Those skilled in the art can choose according to their needs.

[0091] Preferably, the film application device further includes a plurality of anti-slip pads 12 disposed on the lower end surface of the base plate 1.

[0092] It should be noted that by setting multiple anti-slip pads 12 on the lower end surface of the base plate 1, the friction between the protective pads and the operating table is increased, thereby preventing the base plate 1 from sliding relative to the operating table when the pull strip 141 is pulled out.

[0093] Preferably, the third side of the limiting member has a third clearance opening for avoiding the side buttons of the mobile phone 13.

[0094] It should be noted that some of the side buttons of the mobile phone 13 are protruding. When the mobile phone 13 is placed inside the limiting member, in order to avoid the passage of the side buttons of the mobile phone 13, this application provides a third clearance opening on the third side of the limiting member to avoid the side buttons of the mobile phone 13, thereby effectively preventing the side buttons of the mobile phone 13 from affecting the entry of the mobile phone 13 into the limiting member.

[0095] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
