Description

Technical Field

[0001] This utility model relates to the field of lens coating tools, and in particular to a multifunctional tool for applying and removing lens coatings. Background Technology

[0002] The main function of a lens protector is to protect the rear camera lens and metal frame of a mobile phone from scratches and wear. For some high-end products, whose lenses are large and protrude, they are more susceptible to damage in certain environments, making a lens protector necessary.

[0003] In existing technologies, lens coating application methods include manual alignment and application. This method requires a high level of skill and relies solely on experience; beginners are prone to misaligning or prying the coating. Therefore, the industry has developed lens coatings that use molds. A single mold matching the lens model is placed over the lens, enabling automatic alignment and application. Some tools also integrate pry bars for removing old lens coatings; before installing a new coating, the old coatings are carefully removed using the pry bar.

[0004] However, the existing mold-type mounting structure uses pry bars that need to be disassembled one by one, which is not only inefficient, but also requires a fulcrum below, which increases the risk of scratches when the housing near the lens is used as a fulcrum. In addition, these pry bars or notches need to be processed separately on one side of the mold, which not only makes it impossible to be consistent with the overall mold structure, but also increases the processing difficulty.

[0005] In view of this, this technical solution proposes a multifunctional tool for applying and removing lens films. It adopts an inner edge that is directly set at the bottom of the lens film hole and extends towards the center of the hole. When it is necessary to remove the old film, the inner edge is used to lock between the bottom of the lens film and the device housing. After moving it slightly to one side and pulling it up, the old films on the device can be separated. While having the existing film application function, it also improves the efficiency of old film removal and ensures that there is no risk of scratching the device housing. Utility Model Content

[0006] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a multifunctional tool for applying and removing lens coatings, addressing the risks of scratching the lens housing and the low efficiency of removing old coatings in existing lens coating application tools.

[0007] To achieve the above objectives, this utility model provides a multifunctional tool for applying and removing lens coatings, comprising a tool body consisting of a middle frame plate, a lens coating, a surface sealing film, and a bottom sealing film. The middle frame plate has through holes, each of which contains a lens film. The middle frame plate extends from the bottom of the inner wall of the through hole toward the center of the hole to form an inner edge step. The lens film is encapsulated on both sides of the middle frame plate by a surface sealing film and a bottom sealing film, respectively.

[0008] As a further improvement of this utility model, the thickness of the inner edge step is between 0.2mm and 0.6mm.

[0009] As a further improvement of this utility model, the middle frame plate is an integral transparent plastic frame plate structure.

[0010] As a further embodiment of this invention, the top surface of the lens film is bonded to the surface sealing film through the through hole.

[0011] The beneficial effects of this utility model are as follows: This technical solution creates a tool that combines application and removal functions by setting an inwardly extending inner edge step at the bottom of the inner wall of the through hole in the middle frame plate.

[0012] Specifically, when applying a new lens film, the mid-frame plate allows for quick alignment, effectively preventing misalignment. When removing an old film, the inner edge step directly and simultaneously acts on the bottom of all old films, allowing them to be pried up as a whole with simple sliding and lifting movements. This eliminates the inefficiency of traditional prying tools that require individual operation and completely eliminates the risk of scratching the device housing due to prying the fulcrum. A single tool can efficiently and safely complete both operations, significantly improving the user experience. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein.

[0022] Please see the appendix Figure 1-5 , The main body of the film application tool provided by this technical solution consists of a middle frame plate (10), a lens film (11), a surface sealing film (12), and a bottom sealing film (13). The middle frame plate (10) has multiple through holes (100), and each through hole (100) accommodates a lens film (11). The middle frame plate (10) extends from the bottom of the inner wall (101) of the through hole (100) towards the center of the hole to form an inner edge step (102). The lens film (11) is sealed and fixed on both sides of the middle frame plate (10) by the surface sealing film (12) and the bottom sealing film (13).

[0023] When applying a new lens film, the tool is easy to operate. Specifically, first peel off the bottom sealing film (13), align the through hole (100) on the middle frame plate (10) with the lens of the device and cover it down so that the lens film (11) is attached to the lens. Then peel off the surface sealing film (12) and remove the middle frame plate (10) to complete the process. There is no need to manually align it, which reduces the risk of misalignment.

[0024] When removing the old lens film, the inner edge step (102) is directly inserted between the bottom of the old lens film and the equipment housing. By slightly moving the middle frame plate (10) to one side, the inner edge step (102) is pushed into the bottom of the old film. Then, it is pulled up at an angle, so that multiple old films can be peeled off from the equipment at the same time. This avoids the inefficiency of traditional prying plates that need to be removed one by one. It also eliminates the risk of scratches caused by using the equipment housing as a fulcrum when prying. The overall structure is integrally formed, and no additional prying plates are required, which simplifies the manufacturing process.

[0025] It is understandable that the number of through holes (100) can be multiple, such as the three shown in the diagram of this scheme, which can be selected according to the specific equipment lens model, arrangement and quantity.

[0026] Reference Appendix Figure 3 As a preferred embodiment of the present invention, the thickness of the inner edge step (102) of this solution is between 0.2 mm and 0.6 mm. This thickness range is derived from a large number of experiments. It enables the inner edge step (102) to fit the tiny gap between the bottom of most lens films (11) and the device (e.g., mobile phone) housing, so that when the old film is removed, the step can be smoothly inserted and apply an effective frame force.

[0027] Of course, depending on different product design and manufacturing requirements, the thickness of the inner edge step (102) can also be other values, such as slightly thinner than 0.2 mm to pursue more flexible insertion, or slightly thicker than 0.6 mm to enhance its structural strength. These are all feasible alternatives.

[0028] Reference Appendix Figure 2 , 5 As a preferred embodiment of this utility model, the middle frame plate (10) in the solution adopts an integrally molded transparent plastic frame plate structure. The entire middle frame plate (10) is a complete transparent plastic part without splicing gaps. The structure is sturdy, allowing users to clearly observe the alignment of the lens film (11) inside the through hole (100) with the device lens through the middle frame plate (10), which greatly facilitates the calibration and disassembly process when applying the film.

[0029] It is understood that the inner edge step (102) can be provided on either side of the through hole (100). In this embodiment, the inner edge step (102) is provided on the inner side of the through hole (100) near the top surface of the lens film (11).

[0030] Reference Appendix Figure 4 In a preferred embodiment of this invention, the top surface of the lens film (11) passes through the through hole (100) on the middle frame plate (10) and is directly bonded to the surface sealing film (12) instead of wobbling within the through hole (100). When applying the film, the surface sealing film (12) is directly peeled off, and the lens film (11) is peeled off at the same time for free alignment and application. After application, the surface sealing film (12) is peeled off again.

[0031] Alternatively, in another case, first peel off the bottom sealing film (13), align the middle frame plate (10) with the lens hole of the device, press down to make the lens film (11) adhere to the lens, then peel off the surface sealing film (12), and finally take out the middle frame plate (10).

[0032] The following points need to be explained: (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0033] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

[0034] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
