[0032] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] Please refer to Figure 1 The camera module protection assembly 100 is used to attach to the camera module (not shown in the figure) to protect the camera module, and the camera module protection assembly 100 can be detected, burned, turned over, transported, etc. Process together with the camera module when attached to the camera module, without tearing the camera module protection assembly 100 from the camera module, saving the time and process of tearing and pasting the film, improving the preparation efficiency of the camera module, and saving cost.

[0034] The camera module protection assembly 100 includes a protective film 10 and a support 20. Please refer to Figure 2 The protective film 10 includes a glass substrate 11, a first optical film 12 and a second optical film 13. The glass substrate 11 has a high light transmittance, in the present embodiment, the glass substrate 11 can be super high transmittance white glass. Super high transmittance white glass, also known as super white glass or low iron glass, has a light transmittance of more than 91.5%, much higher than the 86% of ordinary glass. The first optical film 12 and the second optical film 13 are respectively arranged on the opposite sides of the glass substrate 11, and the first optical film 12 and the second optical film 13 are configured as anti-reflection films (AR films), wherein the anti-reflection film can reduce the reflection of the protective film 10 to light, increase the light transmittance of the protective film 10, and further improve the light transmittance of the protective film 10. In the present embodiment, the light transmittance of the protective film 10 is greater than or equal to 99%. The support 20 is provided with a light transmission hole 21, the protective film 10 is connected to one side of the support 20 and covers the light transmission hole 21, and the other side of the support 20 is used to connect with the camera module. It can be understood that the connection of the protective film 10 and the one side of the support 20 is that the first optical film 12 or the second optical film 13 is connected with the support 20, and in the present embodiment, the periphery of the second optical film 13 of the protective film 10 is connected with the support 20.

[0035] In actual use, the camera module protection assembly 100 of the embodiment is connected with the support 20 on one side of the protection film 10, and then the other side of the support 20 is connected with the camera module. The support 20 is arranged to facilitate the stable connection of the camera module protection assembly 100 and the camera module, avoid the direct connection of the protection film 10 and the camera module, reduce the connection difficulty of the protection film 10 and the camera module, and ensure the stable use of the protection film 10 by supporting the protection film 10. The protection film 10 includes a glass substrate 11 to ensure the light transmittance of the protection film 10. The first optical film 12 and the second optical film 13 are respectively arranged on the two sides of the glass substrate 11 as anti-reflection films to reduce the reflectivity of the protection film 10 to light and increase the amount of transmitted light of the protection film 10, improve the light transmittance efficiency and performance of the protection film 10, thereby reducing the influence of the protection film 10 on light and improving the light transmittance of the protection film 10, thereby ensuring the accuracy of the camera module during detection, programming and other processes. During detection, programming and other processes, the protection film 10 and the support 20 do not need to be torn off. After being attached to the camera module, the protection film 10 and the support 20 can be tested, programmed, circulated, transported and processed with the camera module, reducing the time and process of tearing off and attaching the protection film 10 and the support 20, improving the preparation efficiency of the camera module, and reducing the preparation cost of the camera module.

[0036] In the embodiment, the thickness of the protection film 10 can be between 0.25 mm and 0.35 mm. Preferably, the thickness of the protection film 10 can be between 0.28 mm and 0.32 mm. For example, the thickness of the protection film 10 can be 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.3 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, etc. In this way, by limiting the thickness range of the protection film 10, the first aspect ensures the structural strength of the protection film 10, and the second aspect ensures that the overall thickness of the camera module protection assembly 100 is within a reasonable range. However, when the thickness of the protection film 10 is less than 0.25 mm, the thickness of the protection film 10 is too thin to ensure the structural strength of the protection film 10, and the protection film 10 is prone to cracking, wrinkling and other conditions, affecting the light transmittance of the protection film 10. When the thickness of the protection film 10 is greater than 0.35 mm, the thickness of the protection film 10 is too thick, which increases the overall thickness of the camera module protection assembly 100 and increases the thickness of the camera module, which is not conducive to the detection, programming and other processes of the camera module.

[0037] In order to further reduce the thickness of the camera module protection assembly 100, in the embodiment, the side of the support 20 facing the protective film 10 is also provided with an embedding groove 22, the embedding groove 22 is arranged around the light hole 21 and communicates with the light hole 21, and the periphery of the protective film 10 is adaptively arranged in the embedding groove 22. Among them, the thickness of the embedding groove 22 can be substantially the same as the thickness of the protective film 10, that is, the protective film 10 is completely arranged in the embedding groove 22; or the thickness of the embedding groove 22 can be smaller than the thickness of the protective film 10, that is, part of the protective film 10 is arranged in the embedding groove 22, and the other part of the protective film 10 protrudes from the support 20. In this way, by arranging the embedding groove 22 on the support 20, the protective film 10 can be embedded in the embedding groove 22, thereby further reducing the thickness of the camera module protection assembly 100. In the embodiment, the shape of the embedding groove 22 is annular, and the shape of the protective film 10 is circular.

[0038] In order to facilitate the external assembly equipment (not shown in the figure) to attach the camera module protection assembly 100 to the camera module, in the embodiment, the support 20 is also provided with a protruding part 23. The external assembly equipment grabs the protruding part 23 to facilitate the attachment of the camera module protection assembly 100 to the camera module, thereby improving the attachment convenience of the camera module protection assembly 100.

[0039] In the embodiment, the thickness of the support 20 can be in the range of 4.1mm to 4.3mm, preferably, the thickness of the support 20 can be in the range of 4.16mm to 4.26mm. For example, the thickness of the support 20 can be 4.1mm, 4.11mm, 4.12mm, 4.13mm, 4.14mm, 4.15mm, 4.16mm, 4.17mm, 4.18mm, 4.19mm, 4.2mm, 4.21mm, 4.22mm, 4.23mm, 4.24mm, 4.25mm, 4.26mm, 4.27mm, 4.28mm, 4.29mm, 4.3mm, etc. In this way, by limiting the thickness range of the support 20, first, the structural strength of the support 20 is guaranteed, and second, the thickness of the camera module protection assembly 100 is within a reasonable range. However, when the thickness of the support 20 is less than 4.1mm, the thickness of the support 20 is too thin, which cannot guarantee the structural strength of the support 20. When the thickness of the support 20 is greater than 4.3mm, the thickness of the support 20 is too thick, which increases the overall thickness of the camera module protection assembly 100, which increases the thickness of the camera module and is not conducive to the detection, burning, etc. process of the camera module.

[0040] In order to realize the connection of the protective film 10 and the support 20, in the embodiment, the camera module protection assembly 100 further comprises a first adhesive 30. The first adhesive 30 can be made of BG glue. The first adhesive 30 is provided with a first light transmission hole 31. The first adhesive 30 is adhered between the periphery of the protective film 10 and the support 20. The first light transmission hole 31 is in communication with the light transmission hole 21. In the embodiment, the first adhesive 30 is matched with the embedding groove 22. The first adhesive 30 is adhered between the periphery of the second optical film 13 of the protective film 10 and the groove bottom of the embedding groove 22 of the support 20. In this way, by setting the above-mentioned first adhesive 30, the stable connection of the protective film 10 and the support 20 is realized.

[0041] In the embodiment, the thickness of the first adhesive 30 can range from 0.02 mm to 0.03 mm. Preferably, the thickness of the first adhesive 30 can be 0.025 mm. It can be understood that the thickness of the first adhesive 30 can also be 0.02 mm, 0.021 mm, 0.022 mm, 0.023 mm, 0.024 mm, 0.026 mm, 0.027 mm, 0.028 mm, 0.029 mm, 0.03 mm, etc. In this way, by limiting the thickness range of the first adhesive 30, on the one hand, the stable connection between the protective film 10 and the support 20 is ensured, and on the other hand, the thickness of the camera module protection assembly 100 is ensured to be within a reasonable range. However, when the thickness of the first adhesive 30 is less than 0.02 mm, the thickness of the first adhesive 30 is too thin, which is not conducive to the connection of the protective film 10 and the support 20. The protective film 10 and the support 20 are prone to unstable adhesion, which affects the stability of the camera module protection assembly 100. When the thickness of the first adhesive 30 is greater than 0.03 mm, the thickness of the first adhesive 30 is too thick, which increases the overall thickness of the camera module protection assembly 100, or increases the depth of the embedding groove 22, which increases the difficulty of setting the embedding groove 22.

[0042] In order to realize the stable connection of the support 20 and the camera module, in the embodiment, the camera module protection assembly 100 further comprises a second adhesive 40 and a third adhesive 50. The second adhesive 40 is provided with a second light transmission hole 41, the second adhesive 40 is adhered to the side of the support 20 away from the protective film 10, the second light transmission hole 41 is in communication with the light transmission hole 21, and the second adhesive 40 can be a sandwiched adhesive. The viscosity of the second adhesive 40 can be greater than or equal to 1500 g. The third adhesive 50 is provided with a third light transmission hole 51, the third adhesive 50 is adhered to the side of the second adhesive 40 away from the support 20, the third adhesive 50 is used for being adhered to the camera module, the third light transmission hole 51 is in communication with the second light transmission hole 41, and the third adhesive 50 is configured as double-sided anti-static silicone. The viscosity range of the third adhesive 50 can be 600 g to 900 g. In this way, by setting the second adhesive 40 and the third adhesive 50 as described above, on the premise of ensuring that the support 20 has a stable connection with the camera module through the second adhesive 40 and the third adhesive 50, the electrostatic effect between the support 20 and the camera module is reduced, the influence of the camera module protection assembly 100 on the detection of the camera module is reduced, and the test accuracy of the camera module is ensured.

[0043] In the embodiment, the thickness range of the third adhesive 50 can be between 0.05 mm and 0.07 mm, preferably, the thickness range of the third adhesive 50 can be between 0.055 mm and 0.065 mm. For example, the thickness of the third adhesive 50 can be 0.05 mm, 0.051 mm, 0.052 mm, 0.053 mm, 0.054 mm, 0.055 mm, 0.056 mm, 0.057 mm, 0.058 mm, 0.059 mm, 0.06 mm, 0.061 mm, 0.062 mm, 0.063 mm, 0.064 mm, 0.065 mm, 0.066 mm, 0.067 mm, 0.068 mm, 0.069 mm, 0.07 mm, etc. In this way, by limiting the thickness range of the third adhesive 50, on the one hand, the stable connection between the support 20 and the camera module is ensured, and on the other hand, the thickness of the camera module protection assembly 100 is ensured to be within a reasonable range. However, when the thickness of the third adhesive 50 is less than 0.05 mm, the thickness of the third adhesive 50 is too thin, which is not conducive to the stable connection of the support 20 and the camera module, and the support 20 and the camera module are prone to unstable connection, which affects the stability of the camera module protection assembly 100. When the thickness of the third adhesive 50 is greater than 0.07 mm, the thickness of the third adhesive 50 is too thick, which increases the overall thickness of the camera module protection assembly 100.

[0044] It can be understood that in other embodiments, the third adhesive 50 can also be omitted. When the third adhesive 50 is omitted, the camera module protection assembly 100 can be connected with the camera module through the second adhesive 40.

[0045] It is apparent that the application is not limited to the details of the foregoing exemplary embodiments, and that the application can be implemented in other specific forms without departing from the spirit or essential characteristics of the application. The present embodiments are therefore considered in all respects to be illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
