Description

Technical Field

[0001] This utility model belongs to the field of electronic product accessories technology, and in particular relates to a film application device. Background Technology

[0002] For electronic devices such as mobile phones and tablets, a soft protective film or tempered glass screen protector is usually applied to the screen to prevent drops and scratches. Conventional methods for applying screen protectors typically involve manual application or the use of a screen protector applicator. Manual application often results in difficulty achieving precise alignment between the screen protector and the device screen, requiring significant time and effort, and easily soiling the adhesive surface. While screen protector applicators offer some alignment capabilities, most require manually removing the release liner before application. However, for soft screen protectors, removing the release liner often causes wrinkles and creases, making proper positioning difficult and still presenting a significant challenge. Utility Model Content

[0003] The technical objective of this invention is to provide a film-applying device that aims to solve the problem of the difficulty in applying soft films in related technologies.

[0004] To solve the above-mentioned technical problems, this utility model provides a film-applying device for applying a soft film to electronic devices. The film-applying device includes: a film-pressing assembly, a film-clamping assembly, a base, and a film-removing component. The base has a positioning groove for placing the electronic device, and a first positioning mechanism is provided at one end of the positioning groove. The soft film includes a protective film for bonding with the electronic device, a first release film connected to the bonding side of the protective film, and a second release film connected to the opposite side of the protective film. A positioning part is provided at one end of the second release film. The film-clamping assembly is used to clamp the positioning part and engage with the first positioning mechanism for positioning. Slide rails are provided on opposite sides of the base. A limiting edge is provided on the bottom side of the film-pressing assembly for sliding engagement with the slide rails. A slot is provided on the top side of the film-pressing assembly for detachably installing the film-removing component. The film-pressing assembly is used to press the protective film in the soft film onto the screen of the electronic device under external force. The surface of the film-removing component is provided with an adhesive part for bonding with the first release film.

[0005] Furthermore, the slot opening faces upward and is tilted towards the front of the pressure film assembly.

[0006] Furthermore, the demolding component includes a first positioning plate fixed to the film pressing assembly and a second positioning plate hinged to the first positioning plate. The second positioning plate is also provided with a locking part on the side away from the hinge part, and an adhesive part is provided on the second positioning plate. The first positioning plate and the second positioning plate are used to cooperate to limit the soft film, and the locking part is used to cooperate with the first positioning plate or the slot to fix it.

[0007] Furthermore, the demolding component is also provided with a clearance groove for the soft film to pass through.

[0008] Furthermore, the pressure film assembly includes a mounting base and a pressing member mounted on the bottom side of the mounting base, a limiting edge is provided on the bottom side of the mounting base, and a slot is provided on the upper side of the mounting base.

[0009] Furthermore, the mounting base includes a base body and side panels connected to both sides of the base body, and the pressing component is a roller installed between the two side panels.

[0010] Furthermore, the membrane clamping assembly is provided with a first magnetic attractor and the bottom side of the mounting base is provided with a second magnetic attractor. The second magnetic attractor is used to attract the first magnetic attractor to achieve initial positioning between the mounting base and the membrane clamping assembly.

[0011] Furthermore, the film clamping assembly has a second positioning mechanism adapted to the first positioning mechanism; of the first and second positioning mechanisms, one is a positioning post and the other is a limiting hole; when the film clamping assembly holding the soft film is installed in place with the base, the first and second positioning mechanisms are engaged in limiting cooperation.

[0012] Furthermore, the membrane clamping assembly includes a first fixing member and a second fixing member that are detachably connected; a positioning hole is provided on the positioning part, a clearance hole is provided on the first fixing member, and a limiting part is provided on the second fixing member that is adapted to the clearance hole; the limiting part is used to pass through the positioning hole and the clearance hole in sequence to limit the soft membrane and the first fixing member.

[0013] Furthermore, a handle is attached to the outside of the base.

[0014] Compared with existing technologies, the film-applying device of this invention has the following advantages: the cooperation between the film clamping assembly and the soft film positioning part can fix one end of the second release film in the soft film to the base, achieving effective positioning of the soft film; after the film pressing assembly is installed in the base, the end of the soft film away from the positioning part can be rolled up, and then one end of the first release film (i.e., the end near the positioning part) can be torn open. The torn part of the first release film is fixed to the adhesive part of the release member. A horizontal pushing force is applied to the film pressing assembly to move it. As the film pressing assembly moves, the first release film is taken away by the release member, and the protective film is pressed onto the screen of the electronic device. After the protective film is completely adhered to the screen, the film pressing assembly is removed, and the second release film is peeled off the protective film. The whole process is simple and convenient to operate, and the positioning effect is good. Attached Figure Description

[0024] Example:

[0025] like Figure 1-5 As shown, in this embodiment, the film application device includes: a film application device for applying a soft film 5 to an electronic device 6, the film application device including: a film pressing assembly 1, a film clamping assembly 2, a base 3, and a film removal component 4; the soft film 5 includes a protective film 53 for bonding with the electronic device 6, a first release film 51 connected to the bonding side of the protective film 53, and a second release film 52 connected to the protective film 53 away from its bonding side, one end of the second release film 52 is provided with a positioning part 521; the base 3 forms a positioning groove 31 for placing the electronic device 6, one end of the positioning groove 31 is provided with The device is equipped with a first positioning mechanism; the film clamping assembly 2 is used to clamp the positioning part 521 and cooperate with the first positioning mechanism for positioning; the base 3 is provided with slide rails 32 on opposite sides, the bottom side of the film pressing assembly 1 is provided with a limiting edge 13 for sliding cooperation with the slide rail 32, the top side of the film pressing assembly 1 is provided with a slot 1121 for installing the release film 4, the film pressing assembly 1 is used to press the protective film 53 in the soft film 5 onto the screen of the electronic device 6 under the action of external force; and the surface of the release film 4 is provided with an adhesive part 42 for bonding with the first release film 51.

[0026] Specifically, the cooperation between the film clamping assembly 2 and the positioning part 521 of the soft film 5 can fix one end of the second release film 52 in the soft film 5 to the base 3, thus achieving effective positioning of the soft film 5. After the film pressing assembly 1 is installed into the base 3, the end of the soft film 5 away from the positioning part 521 can be rolled up, and then one end of the first release film 51 (that is, the end near the positioning part 521) can be torn open. The torn part of the first release film 51 is then bonded and fixed to the adhesive part 42 of the release member 4. A horizontal pushing force is applied to the film pressing assembly 1 to move the film pressing assembly 1 (the direction of movement is as follows). Figure 1 As indicated by the arrow, the pressing assembly 1 moves to remove the first release film 51 from the release 4, while simultaneously pressing the protective film 53 onto the screen of the electronic device 6. After the protective film 53 is fully adhered to the screen, the pressing assembly 1 is removed, and the second release film 52 is peeled off the protective film 53. The whole process is simple and convenient to operate, and the positioning effect is good.

[0027] In this embodiment, the slot opening of the card slot 1121 faces upward and is tilted towards the front of the film pressing assembly 1. This orientation of the slot opening of the card slot 1121 makes it less likely for the film release member 4 to detach from the card slot 1121 during the sliding forward movement of the film pressing assembly 1.

[0028] In one embodiment of this example, such as Figure 1-3 As shown, the release liner 4 also has a clearance groove 41 for the soft film 5 to pass through. That is, the release liner 4 and the slot 1121 are detachably assembled. During the film application process, the end of the soft film 5 away from the positioning part 521 can be passed entirely through the clearance groove 41. Then, the torn part of the first release film 51 is fixed to the adhesive part 42 of the release liner 4. The release liner 4 is then directly inserted into the slot 1121, and subsequent operations can be continued. Of course, in some other application methods, the release liner 4 can also be fixed to the slot 1121 at all times. After the film pressing assembly 1 is installed into the base 3, the end of the soft film 5 away from the positioning part 521 is rolled up and passed through the clearance groove 41. Then, one end of the first release film 51 (that is, the end near the positioning part 521) is torn open, and the torn part of the first release film 51 is fixed to the adhesive part 42 of the release liner 4, and subsequent operations can be continued.

[0029] In another embodiment of this invention, the release liner 4 includes a first positioning plate fixed to the film pressing assembly 1 and a second positioning plate (not shown in the figure) hinged to the first positioning plate. A locking portion is also provided on the side of the second positioning plate away from the hinge, and an adhesive portion 42 is disposed on the second positioning plate. The first and second positioning plates cooperate to limit the position of the soft film 5, and the locking portion cooperates with the first positioning plate or the slot 1121 for fixation. Specifically, by configuring the release liner 4 to open and close on one side, during the film application process, it can not only remove the first release film 51 but also effectively limit and guide the position of the soft film 5 (the unapplied portion), improving the success rate of film application. During the film application process, after the film pressing assembly 1 is installed into the base 3, the second positioning plate can be opened. Then, the end of the soft film 5 away from the positioning part 521 is rolled up and placed above the first positioning plate. The second positioning plate is then closed, so that the soft film 5 can be clamped between the first and second positioning plates. Next, one end of the first release film 51 (i.e., the end near the positioning part 521) can be torn open, and the torn part of the first release film 51 is bonded and fixed to the adhesive part 42 of the second positioning plate. The subsequent film removal operation can then be performed. The method of use is simple and convenient. In some more specific embodiments, a buckle corresponding to the locking part can be provided at the first positioning plate or the slot 1121, so that the side of the second positioning plate away from its hinge side can be engaged and fixed with the first positioning plate or the slot 1121. It is understood that in some embodiments, the locking part may also be a locking protrusion provided on the side of the second positioning plate away from its hinge side. When the second positioning plate needs to be closed, the locking protrusion of the second positioning plate can be directly locked into the corresponding side of the locking groove 1121. There is no limitation here.

[0030] like Figure 4 and 5 As shown, in this embodiment, the film pressing assembly 1 includes a mounting base 11 and a pressing member 12 mounted on the bottom side of the mounting base 11. A limiting edge 13 is disposed on the bottom side of the mounting base 11, and a slot 1121 is disposed on the upper side of the mounting base 11. The pressing member 12 can press the protective film 53 onto the screen of the electronic device 6 during the relative sliding process of the mounting base 11 and the base 3. Further, in this embodiment, the mounting base 11 includes a base body 111 and a surrounding plate 112 connected to both sides of the base body 111, and the pressing member 12 is a roller mounted between the two surrounding plates 112. Using the roller to press the protective film 53 helps to reduce the friction between the pressing part and the soft film 5 during the pressing process and improves the pressing efficiency.

[0031] In this embodiment, the bottom of the base 111 of the mounting base 11 and / or the top of the base 3 are provided with limiting grooves adapted to the film clamping assembly 2; the film clamping assembly 2 can be engaged with the limiting grooves. Specifically, the limiting grooves in this embodiment may include a first limiting groove 1111 and a second limiting groove 34. That is, the bottom of the base 111 of the mounting base 11 has a first limiting groove 1111 that is adapted to the shape of the first fixing member 21. The first limiting groove 1111 is used to limit the engagement with the first fixing member 21, so that the connection between the mounting base 11 and the film clamping assembly 2 is more stable during initial positioning. The top of the base 3 is provided with a second limiting groove 34. The shape and size of the second limiting groove 34 are adapted to the second fixing member 22. The positioning post 33 is connected to the bottom of the second limiting groove 34. Through the cooperation between the second fixing member 22 and the second limiting groove 34, the connection stability between the film clamping assembly 2 and the base 3 can be further improved.

[0032] In this embodiment, the film clamping assembly 2 is provided with a first magnetic attractor, and the mounting base 11 is provided with a second magnetic attractor on its bottom side. The second magnetic attractor is used to attract the first magnetic attractor to achieve initial positioning between the mounting base 11 and the film clamping assembly 2. Before fixing the film clamping assembly 2 and the soft film 5, the film clamping assembly 2 and the soft film 5 can be fixed to the bottom side of the pressing assembly 1 as a whole, that is, the first magnetic attractor and the second magnetic attractor are used to achieve initial positioning between the pressing assembly 1 and the film clamping assembly 2 and the soft film 5; then the pressing assembly 1, the film clamping assembly 2, and the soft film 5 are installed into the base 3 as a whole. After being installed in place, the film clamping assembly 2 and the first positioning mechanism of the base 3 cooperate to fix it, and the assembly process can be completed quickly and efficiently. When applying the film, the user's pushing operation on the pressing assembly 1 can automatically separate the mounting base 11 from the film clamping assembly 2.

[0033] Furthermore, in this embodiment, the film clamping assembly 2 has a second positioning mechanism adapted to the first positioning mechanism; one of the first positioning mechanism and the second positioning mechanism is a positioning post 33, and the other is a limiting hole 222; when the film clamping assembly 2 holding the soft film 5 is installed in place with the base 3, the first positioning mechanism and the second positioning mechanism are in a limiting engagement. One or more limiting holes 222 can be provided, and the number of positioning posts 33 is equal to the number of limiting holes 222. Preferably, the first positioning mechanism is a positioning post 33, and the second positioning mechanism is a limiting hole 222. Through the stable clamping of the positioning part 521 by the film clamping assembly 2 and the limiting engagement between the positioning post 33 and the limiting hole 222, the positioning part 521 can be stably and accurately fixed on the base 3, thereby achieving accurate positioning of the soft film 5 and facilitating the application of the soft film 5. It can be seen that the film application device of this application has a simple overall structure and good positioning effect.

[0034] Furthermore, in this embodiment, the membrane clamping assembly 2 includes a first fixing member 21 and a second fixing member 22 that are detachably connected; a positioning hole 522 is provided on the positioning part 521, a clearance hole 211 is provided on the first fixing member 211, and a limiting part 221 adapted to the clearance hole 211 is provided on the second fixing member 221; the limiting part 221 is used to pass through the positioning hole 522 and the clearance hole 211 in sequence to limit the soft membrane 5 and the first fixing member 21.

[0035] Specifically, the first magnetic chuck can be embedded in the first fixing member 21, and the second magnetic chuck can be embedded on the bottom side of the base 111. The position of the second magnetic chuck is different from that of the pressing member 12. In the direction of sliding film pressing of the film pressing assembly 1, the second magnetic chuck is located behind the pressing member 12. Through the interaction of the first and second magnetic chucks, the initial positioning of the film pressing assembly 1 and the film clamping assembly 2 can be achieved, with good positioning effect.

[0036] In some specific embodiments, a third magnetic attractor is also provided inside the second fixing member 22. When the film pressing assembly 1, the film clamping assembly 2, and the soft film 5 are aligned, the end of the first magnetic attractor away from the second magnetic attractor attracts the third magnetic attractor, causing the first fixing member 21 and the second fixing member 22 to move closer together and clamp the soft film 5. That is, after the positioning part 521 of the soft film 5 is placed between the first fixing member 21 and the second fixing member 22, the magnetic attraction between the first magnetic attractor and the third magnetic attractor can attract the first fixing member 21 and the second fixing member 22 closer together, thereby clamping the soft film 5, which is convenient to use.

[0037] In some specific embodiments, the first fixing member 21 is provided with a clearance hole 211, and the second fixing member 22 has a limiting part 221 adapted to the clearance hole 211. The limiting part 221 is used to pass through the positioning hole 522 and the clearance hole 211 at the end of the soft membrane 5 in sequence, thereby limiting the soft membrane 5 and the first fixing member 21. That is, the positioning part 521 is provided with a positioning hole 522 through which the limiting part 221 passes, and the shapes of the positioning hole 522 and the limiting part 221 are perfectly matched. In use, through the cooperation between the limiting part 221 and the clearance hole 211, the horizontal position of the positioning part 521 can be restricted, thereby achieving precise positioning of the soft membrane 5, and further enhancing the connection stability between the first fixing member 21 and the second fixing member 22. Of course, in some other embodiments, the clearance hole 211 can also be provided on the second fixing member 22, and the limiting part 221 can be provided on the first fixing member 21, which is not limited here.

[0038] In this embodiment, a handle 35 is also connected to the outer side of the base 3. The handle 35 makes it more convenient for users to pick up and remove the film application device.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
