Description

Technical Field

[0001] This utility model relates to the field of protective film technology, and more specifically, to a camera hole protective film that prevents it from falling off. Background Technology

[0002] In the manufacturing process of mobile phone display modules, in order to protect the camera hole from dust, fingerprints or other contaminants and ensure the clarity and functional integrity of the camera, a protective film is usually attached to the camera hole. However, there are some inherent problems in the existing display module camera hole protective film structure design.

[0003] Specifically, existing protective films have an ink-free area at the camera hole location, meaning this area is uncovered by ink and also lacks adhesive. This design results in a slight height difference at the camera hole location, primarily due to the difference in ink and adhesive thickness. This height difference reduces the effective adhesion area of ​​the protective film, making it prone to peeling or shifting at the camera hole. Therefore, we have improved upon this by proposing a non-detachable camera hole protective film. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is that the protective film has a height difference at the camera hole position, which reduces the effective adhesion area of ​​the protective film and makes the protective film easy to lift or shift at the camera hole position.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A protective film for camera apertures that prevents detachment includes: a first non-adhesive PET film and a second non-adhesive PET film connected to the first non-adhesive PET film, wherein the thickness of the second non-adhesive PET film is greater than the thickness of the first non-adhesive PET film. This application, by setting the first and second non-adhesive PET films, with the second non-adhesive PET film being thicker than the first, effectively eliminates the height difference present in existing technologies, thereby reducing the problem of protective film peeling caused by the height difference.

[0007] As an improvement of this utility model, a second non-adhesive PET film is used to cover the camera hole during lamination to compensate for the height difference between the first non-adhesive PET film and the cover plate.

[0008] As an improvement of this utility model, one side of the first non-adhesive PET film is connected to a single-sided adhesive PET film, which is used to adhere to the ink area of ​​the cover plate.

[0009] As an improvement of this utility model, the thickness of the second non-adhesive PET film is equal to the total thickness of the first non-adhesive PET film, the single-sided adhesive PET film, and the cover ink.

[0010] As an improvement of this utility model, a tear-off handle is connected to the side of the first non-adhesive PET film away from the single-sided adhesive PET film.

[0011] As an improvement of this utility model, both ends of the first non-adhesive PET film away from the second non-adhesive PET film are extended, and the number of tear handles is two, with the two tear handles respectively located on the two extended ends of the first non-adhesive PET film.

[0012] As an improvement of this utility model, one end of the tear-off handle is fixedly connected to the first non-adhesive PET film, and the other end of the tear-off handle is a free end.

[0013] As an improvement of this utility model, the free end of the tear-off handle is provided with anti-slip texture to improve the stability when the user holds it.

[0014] As an improvement of this utility model, both the second non-adhesive PET film and the first non-adhesive PET film are antistatic transparent PET films, and the materials can be Maxim MX-50T-2ESD or Pinton PT-PT5050-002AX. The material of the single-sided adhesive PET film is 3M 3M244.

[0015] As an improvement of this utility model, both the first non-adhesive PET film and the second non-adhesive PET film are provided with a protective coating.

[0016] Compared with the prior art, the embodiments of this utility model have the following main advantages:

[0017] To address the problem in existing technologies where a height difference at the camera hole position reduces the effective adhesion area of ​​the protective film, making it prone to lifting or shifting at the camera hole position, this application employs a first non-adhesive PET film and a second non-adhesive PET film. The thickness of the second non-adhesive PET film is greater than that of the first non-adhesive PET film, allowing the extra thickness of the second non-adhesive PET film to eliminate the height difference present in existing technologies, effectively reducing the lifting problem of the protective film caused by the height difference.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] As described in the background section, existing protective films have an ink-free area at the camera hole position, meaning that this area is not covered with ink. At the same time, the protective film is also adhesive-free at the camera hole position. This design results in a slight height difference at the camera hole position, which is mainly composed of the ink thickness and the adhesive layer thickness. Due to the existence of this height difference, the effective adhesion area of ​​the protective film is reduced, making the protective film prone to lifting or shifting at the camera hole position.

[0026] To solve this technical problem, this utility model provides a camera hole protective film that prevents it from falling off.

[0027] For details, please refer to Figures 1-2 The anti-detachment camera hole protective film specifically includes:

[0028] A first non-adhesive PET film 1 and a second non-adhesive PET film 2 connected to the first non-adhesive PET film 1, wherein the thickness of the second non-adhesive PET film 2 is greater than the thickness of the first non-adhesive PET film 1.

[0029] The camera hole protective film provided by this utility model has a first non-adhesive PET film 1 and a second non-adhesive PET film 2. The thickness of the second non-adhesive PET film 2 is greater than that of the first non-adhesive PET film 1. The extra thickness of the second non-adhesive PET film 2 can eliminate the height difference that exists in the prior art, and effectively reduce the problem of the protective film peeling off due to the height difference.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Embodiment 1 of the anti-detachment camera hole protective film of this utility model

[0034] For details, please refer to Figures 1-2 The present invention provides a camera hole protective film to prevent detachment, comprising: a first non-adhesive PET film 1 and a second non-adhesive PET film 2 connected to the first non-adhesive PET film 1. The thickness of the second non-adhesive PET film 2 is greater than the thickness of the first non-adhesive PET film 1. This allows the extra thickness of the second non-adhesive PET film 2 to eliminate the height difference present in the prior art, effectively reducing the problem of the protective film peeling up due to the height difference.

[0035] By setting the thickness of the second non-adhesive PET film 2 to be greater than that of the first non-adhesive PET film 1, this design of the present invention enables the second non-adhesive PET film 2 to compensate for the height difference, allowing the protective film to be evenly stressed in all parts during the bonding process, reducing the lifting phenomenon caused by excessive or insufficient local pressure. Furthermore, by increasing the thickness of the second non-adhesive PET film 2, the present invention transforms the original uneven stress into uniform stress, greatly improving the flatness of the protective film and enhancing its bonding stability on the equipment surface, thereby extending the service life of the protective film.

[0036] From the perspective of protecting the camera aperture, when the protective film peels off, gaps are formed. These gaps become channels for dust, moisture, and other impurities to enter, which may damage the optical performance and internal structure of the camera aperture, such as reducing the clarity of the camera aperture, affecting image quality, and even causing damage to internal components. The design of this utility model reduces peeling, thereby effectively protecting the camera aperture from these adverse factors, ensuring that the camera aperture is always in good working condition, and providing users with a high-quality shooting experience.

[0037] Furthermore, such as Figure 1 As shown, the second non-adhesive PET film 2 is used to cover the camera hole during lamination to compensate for the height difference between the first non-adhesive PET film 1 and the cover plate. Covering the camera hole with the second non-adhesive PET film 2 ensures precise coverage of the camera hole and forms a physical barrier. It can effectively prevent external dust, oil, fingerprints and other possible contaminants from entering the camera hole. Because the camera hole is a very precise component, even tiny dust particles may affect its imaging effect. The coverage of the second non-adhesive PET film 2 reduces problems such as image blurring and spots caused by contaminants entering the camera hole.

[0038] Furthermore, such as Figure 1 As shown, one side of the first non-adhesive PET film 1 is connected to a single-sided adhesive PET film 3, which is used to adhere to the cover plate ink area. The adhesion between the single-sided adhesive PET film 3 and the cover plate ink area provides a stable and reliable bonding method. Its adhesiveness ensures that the protective film can adhere to the cover plate ink area of ​​the device, reducing the movement and sliding of the protective film during daily use. If the protective film is not firmly adhered, it is easy to shift, which may cause the camera hole to lose protection. The firm adhesion of the single-sided adhesive PET film 3 can reduce this situation, ensuring that the protective film is in the correct position and protecting the integrity of the camera hole.

[0039] Furthermore, such as Figure 1 As shown, the thickness of the second non-adhesive PET film 2 is equal to the total thickness of the first non-adhesive PET film 1, the single-sided adhesive PET film 3, and the cover ink, thereby achieving compensation for the height difference.

[0040] Example 2 of the anti-detachment camera hole protective film of this utility model

[0041] The camera hole protective film of this utility model further includes, for example... Figure 1 and Figure 2 As shown, a tear-off handle 4 is connected to the side of the first non-adhesive PET film 1 away from the single-sided adhesive PET film 3; the tear-off handle 4 on the first non-adhesive PET film 1 provides users with a convenient way to operate, making it easier for users to remove the protective film when needed, thus improving the convenience of operation.

[0042] Furthermore, such as Figure 2 As shown, both ends of the first non-adhesive PET film 1 away from the second non-adhesive PET film 2 are extended. There are two tear handles 4, which are respectively set on the two extended ends of the first non-adhesive PET film 1. Existing protective film designs usually have handles on the side of the camera hole, with the handles facing outwards. Although this design makes it easier for users to tear off the protective film, in actual use, the handles are prone to collisions with external objects, further increasing the risk of the protective film lifting, shifting, or even falling off. This application sets the tear handles 4, which were originally protruding from the cover plate, on the extended ends of the first non-adhesive PET film 1, and folds the tear handles 4 inwards in the opposite direction, reducing the impact that the tear handles 4 are prone to due to facing outwards, thereby effectively reducing the problems of lifting, shifting, and falling off caused by the collision of the tear handles 4.

[0043] Furthermore, one end of the tear-off handle 4 is fixedly connected to the first non-adhesive PET film 1, and the other end of the tear-off handle 4 is a free end. The tear-off handle 4 can be set with different colors, such as red, green, blue, yellow, purple, pink, etc., for differentiation and operator identification. With one end of the tear-off handle 4 fixed and the other end free, this structural design makes it more convenient for users to hold. Users can easily grasp the free end and use the connection stability of the fixed end to apply force evenly to the protective film, ensuring that the protective film can be peeled off smoothly. Setting different colored tear-off handles 4 has several advantages. For operators in the production process, they can quickly distinguish different batches, specifications, or types of protective films according to the color, reducing confusion and improving production efficiency and accuracy. In after-sales maintenance or user use, different colors also make it easier for users to quickly identify and operate.

[0044] Furthermore, the free end of the tear-off handle 4 is equipped with an anti-slip texture to improve the stability of the user's grip. In actual operation, the user may be unable to peel off the protective film smoothly due to slipping, or may even make operational errors due to slipping, causing damage to the device. The anti-slip texture increases friction, allowing the user to grip the tear-off handle 4 more firmly during operation, ensuring the safety and accuracy of the operation. Whether in dry or humid environments, it can ensure that the user can operate stably, reducing various problems caused by poor grip and improving the user's operating experience.

[0045] Embodiment 3 of the Anti-detachment Camera Hole Protective Film of this Utility Model

[0046] Furthermore, in this utility model's anti-detachment camera hole protective film, both the second non-adhesive PET film 2 and the first non-adhesive PET film 1 are anti-static transparent PET films. The material can be Maxim MX-50T-2ESD or Pinton PT-PT5050-002AX, and the single-sided adhesive PET film 3 is made of 3M 3M244. Using anti-static transparent PET films as the second non-adhesive PET film 2 and the first non-adhesive PET film 1 is a major advantage of this utility model. In the operating environment of electronic devices, static electricity is a common problem. It may attract surrounding dust, fine fibers, and other impurities. Once these impurities are adsorbed onto the surface of the second non-adhesive PET film 2 and the first non-adhesive PET film 1, they will not only affect the appearance, but more importantly, they will negatively affect the imaging effect of the camera hole, such as causing problems like spots and blurriness in the image. Using anti-static materials can effectively reduce the generation and accumulation of static electricity, ensuring the cleanliness around the camera hole, providing a clean working environment for the camera hole, and ensuring the clarity and quality of the captured image.

[0047] 3M's 3M244 material has good adhesion and stability. Its adhesion remains stable during long-term use, ensuring a firm bond between the protective film and the ink area of ​​the cover plate, and is not prone to failure due to time or environmental changes.

[0048] Furthermore, a protective coating is provided on the surface of both the first non-adhesive PET film 1 and the second non-adhesive PET film 2. The protective coating is used to reduce the damage to the first non-adhesive PET film 1 and the second non-adhesive PET film 2, and to extend the service life of the first non-adhesive PET film 1 and the second non-adhesive PET film 2.

[0049] like Figure 1 , Figure 3 and Figure 4 As shown in the figure, point A is marked as the cover plate, point B is marked as the camera hole position, and point C is marked as the cover plate ink area. In use, the single-sided adhesive PET film 3 is pasted on the cover plate ink area, while the second non-adhesive PET film covers the camera hole position.
