Description

Technical Field

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

[0002] In the field of electronic product screen protector application, the screen protector applicator is a key tool for achieving precise alignment between the screen protector and the product, and its positioning structure design directly affects the application effect. Currently, mainstream screen protector applicators generally employ an upper release liner and a constraint structure scheme when positioning the screen protector: after the upper release liner is applied to the non-adhesive side of the screen protector, the upper release liner is extended outwards to form an extension section. This extension section is then fixed in place by positioning posts, clips, and other constraint structures on the screen protector. The positioning of the screen protector and the applicator is achieved through the adhesion between the two, preventing application misalignment.

[0003] However, the matching requirements between the extension and the constraint structure necessitate additional installation space for the applicator, increasing its overall size. Simultaneously, the constraint structure must ensure clamping stability, requiring improvements such as increased injection precision of the positioning pins and adjustments to the opening and closing angles of the latches. This increases structural complexity and directly raises mold development, production, and assembly costs. Furthermore, the increased size of the applicator can lead to conflicts with miniaturized electronic products. Modern portable cameras, mini smartwatches, and other products have compact designs and limited operating space. The edges of the applicator may collide with protruding structures (such as camera lenses) or obstructing components (such as side buttons), hindering operation and potentially scratching the product or damaging the applicator, thus reducing safety.

[0004] Taking a small camera as an example, it has a main display screen on one side and a front display screen and lens on the other side, requiring at least three protective films to be applied. In the existing positioning solutions, each protective film needs to be matched with a dedicated film applicator, and a set of protective films requires multiple film applicators. This increases the amount of packaging materials used and the complexity of the process, increases the risk of warehousing and transportation, and requires users to operate different film applicators one by one, which is cumbersome and prone to errors, affecting the user experience.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A simple film product includes a rigid board, an adhesive layer, at least one protective film, and at least one release film corresponding to the protective film. The lower end of the rigid board has at least one product edge positioning groove corresponding to the protective film. A film positioning window penetrating the upper end of the rigid board is formed in the product edge positioning groove. The adhesive layer is adhered to the rigid board, and the protective film is positioned within the film positioning window. The protective film has a protective layer and an optical adhesive layer adhered to the protective layer. The protective layer is attached to the adhesive layer through the film positioning window, and the release film is adhered to the optical adhesive layer.

[0008] Preferably, the rigid sheet is made of transparent acrylic material and is coated with a printed layer.

[0009] Preferably, the adhesive layer is made of PET material.

[0010] Preferably, a pressing window is provided on the adhesive layer, and the pressing window corresponds to the vertical projection area of ​​the film positioning window.

[0011] Preferably, a directional guide portion is also formed extending along the edge of the rigid plate.

[0012] Preferably, the protective layer is made of tempered glass.

[0013] Preferably, the protective layer is made of tempered glass material with an AR anti-reflective coating.

[0014] Preferably, the optical adhesive layer is made of anti-glare AB adhesive material.

[0015] Preferably, one side of the release film extends into a tear-off portion, and the side of the product edge positioning groove is also provided with a clearance portion that penetrates the side of the rigid plate, the clearance portion corresponding to the tear-off portion.

[0016] Compared with the prior art, the beneficial effects of this utility model are: There is no need to set an extension in the upper release film or add positioning posts to the film applicator. The rigid plate can achieve dual positioning through the product edge positioning groove and the film positioning window, which greatly simplifies the structure, effectively controls the size of the rigid plate, avoids space conflicts with small products, and reduces mold development and production assembly costs. For products that require multiple protective films, such as small cameras, positioning grooves and film positioning windows for the corresponding protective films can be opened on the same rigid board. Multiple protective films can be stably fixed with only one adhesive layer, eliminating the need for a separate adhesive structure for each protective film. This further simplifies the overall product structure, reduces material usage, and lowers production and assembly costs. At the same time, it ensures the consistency of the position of multiple protective films on the rigid board and improves the accuracy of multi-area film application. In addition, for characteristic components such as the shutter button and power button on the side of the camera, the directional guide can be set in a position that matches these components, and a pattern that matches the shape or logo of the shutter button or power button can be printed on the printing layer for quick identification. When applying the screen protector, the user only needs to align the pattern on the directional guide with the actual camera component to ensure that the screen protector is correctly positioned with the camera, solving the problem of misalignment causing the screen protector to deviate from the camera screen, and further improving the ease of operation and the success rate of screen protector application.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022]

Example 1

[0023] The rigid plate 10 is made of transparent acrylic material and is coated with a printed layer. It has sufficient structural strength to stably support the protective film 30 and ensure accurate positioning. Its transparency also allows users to visually observe the alignment of the protective film 30 with the camera screen during the application process, reducing the risk of misalignment. The adhesive layer 20 is made of PET material, which can firmly fix the protective film 30. The protective layer 31 is made of tempered glass material, which can provide high-strength scratch and drop protection for the camera screen and extend the screen's lifespan. The optical adhesive layer 32 is made of anti-glare AB glue material, which can effectively reduce the reflection interference of strong outdoor light on the screen and play an anti-glare role when using the screen outdoors. This allows users to clearly see the screen content when using the camera outdoors, improving the adaptability of the usage scenario.

[0024] A pressing window 21 is provided on the adhesive layer 20, which corresponds to the vertical projection area of ​​the film positioning window 12. When applying the film, the user can directly press the protective film 30 without avoiding the adhesive layer 20, ensuring that the optical adhesive layer 32 is tightly attached to the camera display screen, avoiding problems such as inadequate pressing and air bubbles caused by the adhesive layer 20 blocking the film. After the film is applied, the user can directly press the protective film 30 with their fingers and then pry open the rigid plate 10, without causing the protective film 30 to be torn when removing the rigid plate 10.

[0025] A directional guide portion 13 is also formed extending from the edge of the rigid plate 10. A guide pattern is provided on the directional guide portion 13 in the printed layer. When applying the protective film 30 to the camera screen, in order to prevent the incorrect orientation of the protective film product and the camera from causing a positional error between the applied protective film 30 and the camera screen, a corresponding directional guide portion 13 is set according to the button position on the side of the camera, such as the shutter button, the power button, etc., corresponding to the position of the shutter button, the power button, etc., and a corresponding pattern that can be quickly identified is set on the printed layer, thereby helping the user to avoid directional errors when positioning the camera and the protective film product.

[0026] The release film 40 has a tear-off part 41 extending from one side, and the product edge positioning groove 11 also has a clearance part 14 that penetrates the side of the rigid plate 10. The clearance part 14 corresponds to the tear-off part 41, providing a dedicated space for the tear-off part 41 to accommodate and operate. Users do not need to find an extra point of force, and can easily pinch the tear-off part 41 to tear off the release film 40, avoiding accidental contact with the protective film 30 during the tearing process and causing position displacement, thus improving the smoothness of operation.

[0027]

Example 2

[0028] By creating two product edge positioning grooves 11 and film positioning windows 12 on the same rigid plate 10 corresponding to the display screen and lens, two protective films 30 are integrated and fixed to the same carrier. This eliminates the need for separate film applicators for the display screen and lens. Users only need to position the rigid plate 10 once to simultaneously complete the film application for both areas. Of course, for cases where the lens and display screen are at different heights, film application can also be completed by two separate positioning operations. This solves the pain point of cumbersome multi-area film application for cameras, improving application efficiency and overall accuracy. Compared to traditional dual film applicator solutions, this reduces the number of products and packaging materials, lowering warehousing and transportation costs. Simultaneously, it eliminates the need to increase the size of the rigid plate 10, still fitting the compact appearance of the camera and avoiding space conflicts with other components. It balances multi-functional integration and miniaturization requirements, fully meeting the professional needs of multi-area film application for cameras.

[0029] The rigid plate 10 is made of transparent acrylic material, and a printed layer is coated on it. It possesses sufficient structural strength to stably support the protective film 30 and ensure accurate positioning. Its transparency allows users to visually observe the alignment of the protective film 30 with the camera display during application, reducing the risk of misalignment. The adhesive layer 20 is made of PET material, which firmly secures the protective film 30. The protective layer 31 is made of tempered glass, providing high-strength scratch and drop protection for the camera display and extending its lifespan. Furthermore, for lens-based protective films, the protective layer 31 is made of tempered glass with an AR anti-reflective coating, reducing light refraction loss, improving lens light intake and image quality, achieving optimal functionality for both components with a single plate.

[0030] In terms of selection, the optical adhesive layer 32 is based on the protective film 30 of the display screen. Its optical adhesive layer 32 is made of anti-glare AB glue material, which can play an anti-glare role for the screen when used outdoors, reduce the reflection of strong outdoor light, and ensure the clarity of screen viewing.

[0031] A pressing window 21 is provided on the adhesive layer 20, which corresponds to the vertical projection area of ​​the film positioning window 12. The pressing window 21 on the adhesive layer 20 exposes the core bonding area of ​​the protective film 30, making it convenient for users to press and ensure a tight bond. More importantly, after the film is applied, the user can directly press the protective film 30 and then pry open the rigid plate 10. Since the protective film 30 is firmly bonded to the camera component through the optical adhesive layer 32, and the rigid plate 10 is only connected to the protective layer 31 of the protective film 30 through the adhesive layer 20, the protective film 30 will not be pulled off when separated. This solves the problem of the protective film 30 being easily torn off when removing it with a traditional film applicator, ensuring the stability of the film application results and reducing the risk of rework.

[0032] The release film 40 has a tear-off part 41 extending from one side, and the product edge positioning groove 11 also has a clearance part 14 that penetrates the side of the rigid plate 10. The clearance part 14 corresponds to the tear-off part 41, providing a dedicated space for the tear-off part 41 to accommodate and operate. Users do not need to find an extra point of force, and can easily pinch the tear-off part 41 to tear off the release film 40, avoiding accidental contact with the protective film 30 during the tearing process and causing position displacement, thus improving the smoothness of operation.

[0033]

Example 3

[0034] The rigid plate 10 is made of transparent acrylic material, which has sufficient rigidity to support the small watch screen protector 30 and prevent deformation during positioning. Its transparency also allows users to observe the alignment status of the film in real time, making it especially suitable for the small and exquisite features of watch screens. The adhesive layer 20 is made of PET material, which can firmly fix the protective film 30 and will not cause the protective film 30 to shift when the rigid plate 10 is removed due to excessive adhesive force.

[0035] The protective layer 31 is made of tempered glass, which can resist scratches that may be encountered during daily wear of the watch, extend the screen's lifespan, and reduce the reflection of outdoor sunlight or strong indoor light on the screen. Even when checking the watch time and sports data outdoors, the screen content can still be clearly seen, making it suitable for high-frequency outdoor use scenarios. One side of the release film 40 extends with a tear-off part 41, and the side of the product edge positioning groove 11 also has a clearance part 14 that penetrates the side of the rigid plate 10. The clearance part 14 corresponds to the tear-off part 41, providing dedicated space for the tear-off part 41 to accommodate and operate. Users do not need to find an extra point of force; they can easily pinch the tear-off part 41 to tear off the release film 40, avoiding accidental contact with the protective film 30 during the tearing process and improving the smoothness of operation.

[0036] Therefore, the above three embodiments, which are respectively designed for the film application needs of single camera displays, integrated camera displays and lenses, and watch screens, all adopt a structure based on a transparent acrylic rigid plate 10 and a PET adhesive layer 20. They are combined with a film positioning window 12 and a product edge positioning groove 11 to achieve precise positioning. Combined with an optical adhesive layer 32 with anti-glare and other functions, and a tear-off release film 40 with a clearance part 14, the film application accuracy and usability are ensured while simplifying operation, reducing costs, and meeting the film application needs of different small electronic products.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
