Description

Technical Field

[0001] This utility model relates to the field of film application technology, and in particular to a film application component. Background Technology

[0002] During the screen protector application process, to avoid issues like misalignment and air bubbles that are common with manual application, auxiliary application tools are typically used. For ease of use, the applicator and the protective film are usually assembled together, and a positioning film and a pull strap are also fixed to the applicator to secure the protective film. However, due to the prolonged fixation from manufacturing to use, the pull strap, positioning film, and protective film are easily compressed by the pull strap or positioning film, causing changes in the thickness of the adhesive coating on the protective film. This can lead to incomplete adhesion and air bubbles when the protective film is applied to the screen of electronic devices. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a film-applying assembly, which keeps the pull strap and the release film in a separate state by positioning grooves in the through holes, so as to avoid the pull strap pressing on the release film and affecting the change of adhesive thickness on the protective film.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A film application assembly includes: a film applicator having a thickness direction, the film applicator having a recessed receiving groove for accommodating an electronic device along the thickness direction; a protective film assembly including a positioning film, a protective film, a release film, and a pull strap stacked sequentially, the protective film assembly being fixed in the receiving groove by the positioning film, the pull strap having a first end connected to the release film and a second end opposite to the first end; a through hole being formed in the side wall of the receiving groove corresponding to the second end, the through hole having a bottom wall located on one side of the bottom of the receiving groove and a top wall opposite to the bottom wall, the top wall having a recessed positioning groove in a direction away from the bottom wall, and the second end being fixed in the positioning groove.

[0006] As a further improvement to this solution, a positioning part is provided in the positioning groove, the positioning part is formed with a hook, and a positioning hole is opened at the second end, the positioning hole is sleeved on the positioning part and engages with the hook.

[0007] As a further improvement to this solution, the positioning part protrudes from the bottom of the positioning groove toward the bottom wall, and the positioning part is provided with a first guide surface on the side facing the receiving groove. The first guide surface has a first guide edge away from the bottom of the receiving groove and a second guide edge close to the bottom of the receiving groove. The first guide surface is inclined from the first guide edge to the second guide edge toward the side away from the receiving groove.

[0008] As a further improvement to this solution, the positioning film extends toward the positioning groove to form an extension portion, the orthographic projection of the extension portion along the thickness direction is located outside the protective film, and the extension portion is located inside the through hole and abuts against the top wall.

[0009] As a further improvement to this solution, the top wall is provided with a support portion protruding towards the bottom wall, and the extension portion at least partially abuts against the support portion.

[0010] As a further improvement to this solution, the support portions are respectively provided on both sides of the positioning groove, and the support portions are symmetrically arranged on both sides of the positioning groove.

[0011] As a further improvement to this solution, the support portion is provided with a second guide surface on the side facing the receiving groove. The second guide surface has a third guide edge away from the bottom of the receiving groove and a fourth guide edge close to the bottom of the receiving groove. The second guide surface is inclined from the third guide edge to the fourth guide edge in the direction away from the receiving groove.

[0012] As a further improvement to this solution, the support portion and the positioning portion each have a first abutting surface and a second abutting surface that abut against the extension portion. The first abutting surface and the second abutting surface are located on the same plane, and the extension portion abuts against the first abutting surface and the second abutting surface.

[0013] As a further improvement to this solution, the protective film assembly is disposed at the bottom of the receiving groove, and the side wall of the receiving groove is provided with a plurality of protrusions for supporting electronic devices. The side of the protrusion away from the bottom of the receiving groove is a support surface, and the distance from the support surface to the bottom of the receiving groove is greater than the distance from the abutment surface to the bottom of the receiving groove.

[0014] As a further improvement to this solution, a clearance notch is provided on the side of the bottom wall near the through hole. The clearance notch is recessed towards the receiving groove. The film applicator has a length direction and a width direction. The first end is located at one end of the length direction, and the second end is located at the other end of the length direction.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0025] Reference Figures 1 to 6 This utility model provides a film-applying assembly for assisting users in applying films to electronic devices. The assembly includes an applicator 1 and a protective film assembly 2. Both the electronic device and the protective film assembly 2 are disposed within the assembly, and are positioned by the assembly to ensure proper film application. The applicator 1 has a thickness direction, and a recessed receiving groove 11 is formed along its thickness direction. Both the electronic device and the protective film assembly 2 are disposed within the receiving groove 11, ensuring the device is stably placed and preventing displacement or sliding during application. The protective film assembly 2 includes a positioning film 21, a protective film 22, a release film 23, and a pull strap 24, which are stacked sequentially. The protective film 22 has a usable surface and an adhesive surface. Adhesive is provided on the adhesive surface. The positioning film 21 is stacked on the usable surface of the protective film 22, the release film 23 is stacked on the adhesive surface of the protective film 22, and the pull strap 24 is stacked on the side of the release film 23 away from the protective film 22. The receiving groove 11 of the film applicator 1 is provided with a snap-fit ​​structure, and the corresponding positioning film 21 is provided with a snap-fit ​​position. The positioning film 21 is snap-fitted and fixed to the film applicator 1. The protective film assembly 2 is fixed in the receiving groove 11 through the positioning film 21, so that the protective film 22 is positioned on the screen of the electronic device.

[0026] One end of the pull strap 24 is connected to the release film 23, while the other end remains separate from the release film 23, forming a free end, allowing the user to pull the pull strap 24 to peel off the release film 23. The protective film assembly 2 is located on the side of the receiving groove 11 near the bottom of the groove, the electronic device is located on the side of the protective film assembly 2 away from the bottom of the groove, the positioning film 21 is located on the side of the protective film assembly 2 near the bottom of the groove, and the pull strap 24 is located on the side of the protective film assembly 2 near the electronic device.

[0027] The pull strap 24 is connected to the release film 23 at one end, which is designated as the first end 241, and the other end as the second end 242. During the application process, the user pulls the second end 242 of the pull strap 24 to peel the release film 23 off the protective film 22. A through hole 111 is provided on the side wall of the receiving groove 1 corresponding to the second end 242. The pull strap 24 and the release film 23 can be pulled out of the applicator 1 through these through holes 111. After the pull strap 24 is peeled off from the release film 23, the adhesive surface of the protective film 22 adheres to the screen of the electronic device.

[0028] Furthermore, the through hole 111 has a bottom wall 101 and a top wall 102 that are opposite each other along the depth direction of the receiving groove 11. The bottom wall 101 is located on the side where the bottom of the receiving groove 11 is located, and the top wall 102 is located on the side opposite to the bottom wall 101. The top wall 102 is recessed with a positioning groove 112 for fixing the second end 242 of the pull strap 24. Since the release film 23 and the protective film 22 are close to the side of the bottom wall 101, when the second end 242 of the pull strap 24 is fixed in the positioning groove 112 on the side of the top wall 102, the pull strap 24 and the release film 23 are kept at a certain separation. This can prevent the pull strap 24 from pressing on the protective film 22 for a long time, and prevent the adhesive layer of the protective film 22 from being squeezed. This ensures that the adhesive layer is more uniform and does not deform, and ensures that the protective film 22 is more tightly and flat when it is applied, thereby improving the success rate of film application.

[0029] In this invention, the applicator 1 is a cuboid structure with a length direction and a width direction. The pull strap 24 is arranged along the length direction of the applicator 1, with the first end 241 located at one end of the length direction and the second end 242 located at the other end of the length direction. Since the first end 241 of the pull strap 24 is connected to one end of the release film 23, the thickness at the connection point is relatively large. During the process of pulling and peeling off the release film 23, the connection point between the first end 241 and the release film 23 needs to pass through the through hole 111, which can easily cause obstruction at the through hole 111, especially when the pull strap 24 contacts the bottom wall 101, which may cause friction or jamming. Therefore, a clearance notch 15 is provided in the bottom wall 101 of the positioning groove 112. Specifically, the clearance notch 15 is recessed towards the receiving groove 11 and extends along the width direction of the applicator 1, and the length of its two ends exceeds the range of the positioning groove 112, thereby providing a more spacious space for the removal of the pull strap 24. The position and structure of the clearance notch 15 allow the pull belt 24 and release film 23 to smoothly bypass the obstruction of the bottom wall 101 and pass through the through hole 111, further reducing friction and resistance during operation and avoiding the problem of the bottom wall 101 hindering the movement of the pull belt 24.

[0030] Preferably, in order to more stably fix the second end 242, a positioning part 12 is provided on the bottom wall 101 of the positioning groove 112, and a positioning hole 243 is provided on the second end 242. The positioning hole 243 corresponds to the positioning part 12 and is engaged with the positioning part 12, so that the second end 242 is fixedly attached to the positioning part 12, so that the pull strap 24 is close to the bottom wall 101 of the positioning groove 112 and away from the release film 23. At the same time, it ensures that the second end 242 of the pull strap 24 can be firmly fixed in the positioning groove 112 before use, so as to avoid displacement or detachment of the pull strap 24.

[0031] A hook structure is formed on the positioning part 12, and the positioning hole 243 is fitted onto the positioning part 12 and engages with the hook. Specifically, a cantilever 121 extends outward from the side of the positioning part 12 away from the receiving groove 11. The side of the cantilever 121 facing the top wall 102 is the abutment surface, and the positioning hole 243 is correspondingly engaged with the cantilever 121, so that the abutment surface of the second end 242 is pressed down, thereby moving the second end 242 away from the release film 23. The cantilever 121 ensures that the positioning part 12 maintains good elasticity and load-bearing capacity while fixing the pull strap 24, so that the pull strap 24 is not excessively disturbed by the shape or position of the positioning part 12 during use, and at the same time, it can prevent the pull strap 24 from shifting left and right.

[0032] Furthermore, the positioning part 12 protrudes towards the bottom wall 101 of the receiving groove 11, and the cantilever 121 is provided in the protruding part 122. The positioning hole 243 passes through the cantilever 121 and the protruding part 122 respectively, so that the second end 242 is more firmly fixed in the positioning groove 112.

[0033] The positioning part 12 also has a chamfer on the side facing the receiving groove 11. Specifically, the positioning part 12 has a first guide surface on the side facing the receiving groove 11. This guide surface has two boundaries: a first guide edge away from the bottom of the receiving groove 11 and a second guide edge near the bottom of the receiving groove 11. The first guide surface is inclined from the first guide edge to the second guide edge, tilting away from the receiving groove 11, so that the first guide surface forms a chamfer on the positioning part 12. The inclined design of the first guide surface reduces the resistance encountered by the pull strap 24 when pulling the release film 23. Especially when the pull strap 24 passes through the through hole 111, the chamfer can effectively avoid the sharp part of the positioning part 12 from blocking the pull strap 24, improving the smoothness during use.

[0034] To further optimize the structure and function of the protective film assembly 2, specifically, the positioning film 21 extends from the edge near the second end 242 with an extension 211. The orthographic projection of this extension 211 along the thickness direction of the applicator 1 is located outside the protective film 22. This ensures that the positioning film 21 at least partially covers the protective film 22 and at least partially does not overlap or contact the protective film 22. Simultaneously, the extension 211 is also located within the through-hole 111 of the receiving groove 11. During the application process, when the applicator 1 is inverted and the top wall 102 is below the bottom wall 101, the positioning film 21 is pressed down by gravity, and the extension 211 can be supported on the top wall 102. Since the pull strap 24 is in the recessed positioning groove 112 within the top wall 102, the top wall 102 can abut against the positioning film 21, preventing the positioning film 21 from continuing to be pressed down and thus adhering to the pull strap 24. Since the top of the positioning part 12 in the positioning groove 112 facing the bottom wall 101 can also contact the positioning film 21, it abuts against the positioning film 21 to prevent it from continuing to press down.

[0035] A support portion 13 protrudes from the top wall 102 towards the bottom wall 101, and the extension portion 211 at least partially abuts against the support portion 13, thereby further optimizing the relative position between the release film 23 and the pull strap 24. The protruding design of the support portion 13 allows the positioning film 21 to rise when the extension portion 211 contacts the support portion 13, thus simultaneously raising the release film 23 and ensuring it maintains an appropriate height during the application process. This prevents the pull strap 24 from directly contacting the release film 23, further preventing the adhesive layer of the protective film 22 from being compressed and deformed. Furthermore, support portions 13 are provided on both sides of the positioning groove 112. The symmetrical arrangement of the support portions 13 ensures that the positioning film 21 receives uniform and balanced support during the application process, improving the stability and support effect of the positioning film 21 and preventing the extension portion 211 from shifting or experiencing uneven stress during use.

[0036] To further improve the smoothness of the pull strap 24 and release film 23 passing through the through hole 111, a chamfer is provided on the side of the support portion 13 facing the receiving groove 11, transforming the sharp edge of the support portion 13 into a smooth bevel. Specifically, a second guide surface is provided on the side of the support portion facing the receiving groove. This second guide surface also has two boundaries: a third guide edge away from the bottom of the receiving groove and a fourth guide edge near the bottom of the receiving groove. The inclined structure of the second guide surface from the third guide edge to the fourth guide edge is inclined in the direction away from the receiving groove 11, forming a chamfer on the support portion 13. The chamfer makes the edge of the support portion 13 smoother, reducing the friction and resistance between the pull strap 24 and the support portion 13 when pulling the release film 23, thereby ensuring that the release film 23 can more easily detach from the protective film 22 and pass smoothly through the through hole 111. When the pull strap 24 pulls the release film 23, the second guide surface of the support portion 13 guides the pull strap 24 to slide along the inclined path, allowing it to pass through the support portion 13 more smoothly.

[0037] The support portion 13 and the positioning portion 12 are provided with contact surfaces that abut against the positioning film 21 of the extension portion 211. The support portion 13 has a first contact surface, and the positioning portion 12 has a second contact surface, ensuring that the contact surfaces can abut against the positioning film 21 and prevent the protective film 22 from pressing against the pull strap 24 when the film is inverted. The first contact surface and the second contact surface are located on the same plane, and the extension portion 211 of the positioning film 21 abuts against the first contact surface and the second contact surface, so that the extension portion 211 is evenly and precisely supported on the plane, ensuring that the protective film assembly 2 is always kept in the predetermined position.

[0038] In this embodiment, the protective film assembly 2 is disposed at the bottom of the receiving groove 11. To prevent the electronic device from prematurely contacting the protective film 22 when it is assembled into the receiving groove 11, several protrusions 14 are added to the side wall of the receiving groove 11. The side of the protrusion 14 away from the bottom of the receiving groove 11 is a support surface, which is used to contact and support the electronic device. Specifically, the distance from the support surface of the protrusion 14 to the bottom of the receiving groove 11 is greater than the distance from the abutment surface of the support part 13 and the positioning part 12 to the bottom of the receiving groove 11, so that the distance from the screen of the electronic device to the bottom of the receiving groove 11 is greater than the distance from the protective film assembly 2 to the bottom of the receiving groove 11, thus creating a gap between the screen of the electronic device and the protective film 22. By lifting the electronic device with the protrusions 14, an initial appropriate distance is maintained between the electronic device and the release film 23. This structural design can effectively prevent the electronic device from prematurely pressing onto the release film 23 during the film application process.

[0039] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
