[0036] The camera is a core functional component and visual focal point of electronic devices. Camera decorative parts are used to decorate the camera. These parts not only effectively fix and protect the camera but also conceal parts of its structure, thus improving its appearance. However, during the assembly of camera decorative parts with the camera, limitations in the precision of dust control in the production environment can easily lead to the accumulation of tiny foreign objects such as white spots and lint. These residues, if they fall onto the camera after assembly, can affect the electronic device's photographic function and overall appearance.

[0037] To prevent residual white spots, lint, or other minute foreign matter from affecting the camera's photographic function and appearance after the camera trim is assembled with the camera module, this application provides a camera trim in its first aspect. In one embodiment, please refer to... Figure 1 and Figure 2 The camera decorative component 10 includes a decorative component body 11 and a dust-absorbing adhesive layer 12. The decorative component body 11 has a first surface 11A and a second surface 11B that are disposed opposite to each other. The decorative component body 11 is provided with a through hole 13, which penetrates the first surface 11A and the second surface 11B. The through hole 13 includes a preset hole segment 131. The inner wall of the preset hole segment 131 is used to surround the camera module 40 to form a receiving space 13A for accommodating the camera. The dust-absorbing adhesive layer 12 covers the inner wall of the preset hole segment 131.

[0038] The camera decorative component 10 of the above embodiment is provided with a through hole 13, which includes a preset hole segment 131. The inner wall of the preset hole segment 131 is used to form a receiving space 13A for accommodating the camera with the camera module 40. In this embodiment, a dust-absorbing adhesive layer 12 is provided on the inner wall of the preset hole segment 131, which can adsorb small foreign objects such as white spots and lint. The dust-absorbing adhesive layer 12 covers the inner wall of the preset hole segment 131, which can maximize the adsorption area of ​​the dust-absorbing adhesive layer 12 and ensure the adsorption effect. After the camera decorative component 10 of this embodiment is assembled with the camera module 40, it can effectively prevent the residue of small foreign objects such as white spots and lint, avoid affecting the product's photography function, and ensure the product's appearance yield. Moreover, the design of the dust-absorbing adhesive layer 12 can achieve self-adsorption of small foreign objects such as white spots and lint, which can reduce production costs compared to manual cleaning.

[0039] Please see Figure 2 In this embodiment, the preset hole segment 131 includes an irregular hole segment 1311, which includes a first irregular hole segment 1311A. The first irregular hole segment 1311A has a rounded inner wall 1311a, and the dust-absorbing adhesive layer 12 covers the rounded inner wall 1311a. Generally, through holes with cylindrical hole segments are more common. In this embodiment, an irregular hole segment is defined as a hole segment other than a cylindrical hole segment. By designing irregular hole segments, special user needs can be met. In this embodiment, the irregular hole segment 1311 includes a first irregular hole segment 1311A, which has a rounded inner wall 1311a. The design of the rounded inner wall 1311a can prevent scratches on parts or personnel during assembly and can provide a smooth transition, reduce the stress concentration coefficient at the hole edge, thereby improving the fatigue life and reliability of the parts.

[0040] In this embodiment, the preset hole segment 131 further includes a cylindrical hole segment 1312, which is connected to the irregular hole segment 1311. The first irregular hole segment 1311A with a rounded inner wall 1311a is located at the end of the preset hole segment.

[0041] In other optional embodiments, the preset hole segment also includes a cylindrical hole segment, the number of cylindrical hole segments is at least one segment, the cylindrical hole segments and the irregular hole segments are interconnected, the number of first irregular hole segments is at least one segment, and the first irregular hole segment is located at the end or middle of the preset hole segment.

[0042] For example, in another embodiment, the first irregularly shaped hole segment is located in the middle of a preset hole segment. See also... Figure 3 and Figure 4The camera decorative component 20 includes a decorative component body 21 and a dust-absorbing adhesive layer 22. The decorative component body 21 has a first surface 21A and a second surface 21B that are disposed opposite to each other. The decorative component body 21 is provided with a through hole 23, which penetrates the first surface 21A and the second surface 21B. The through hole 23 includes a preset hole segment 231. The inner wall of the preset hole segment 231 is used to surround the camera module 50 to form a receiving space 23A for accommodating the camera. The preset hole segment 231 includes a first cylindrical hole segment 2312A, a first irregular hole segment 2311A, and a second cylindrical hole segment 2312B. The diameters of the first cylindrical hole segment 2312A and the second cylindrical hole segment 2312B are different. The first irregular hole segment 2311A is located between the first cylindrical hole segment 2312A and the second cylindrical hole segment 2312B, connecting the first cylindrical hole segment 2312A and the second cylindrical hole segment 2312B. The first irregularly shaped hole segment 2311A has two rounded inner wall sections 2311a and 2311b, and the dust-absorbing adhesive layer 22 covers the rounded inner wall sections 2311a and 2311b. In this embodiment, the first irregularly shaped hole segment 2311A is located between the first cylindrical hole segment 2312A and the second cylindrical hole segment 2312B with different hole diameters, and the two rounded inner wall sections 2311a and 2311b can provide a smooth transition.

[0043] In the above embodiments, the axial dimensions of the inner walls 1311a, 2311a, and 2311b of the rounded corner surfaces are relatively small. Optionally, the axial dimension of the inner wall of the rounded corner surface is 0.35mm to 5mm. For example, the axial dimensions inside the rounded corner surface are 0.35mm, 0.5mm, 1mm, 2mm, 3mm, 4mm, and 5mm.

[0044] In the above embodiments, the irregularly shaped aperture segment includes a first irregularly shaped aperture segment with a rounded inner wall, and a dust-collecting adhesive layer covers the rounded inner wall. In other optional embodiments, the irregularly shaped aperture segment includes a second irregularly shaped aperture segment, which includes one or more of a prism-shaped aperture segment, a frustum-shaped aperture segment, and a frustum-shaped cone aperture segment. The radial cross-section of the second irregularly shaped aperture segment can be polygonal or circular. The polygon can be quadrilateral, pentagonal, hexagonal, heptagonal, or octagonal. Providing several second irregularly shaped aperture segments helps to design the shape of the aperture segments to correspond to the shape of the camera in the camera module.

[0045] For example, in another embodiment, the irregularly shaped hole segment includes a second irregularly shaped hole segment. See also... Figure 5 and Figure 6The camera decorative component 30 includes a decorative component body 31 and a dust-absorbing adhesive layer 32. The decorative component body 31 has a first surface 31A and a second surface 31B that are disposed opposite to each other. The decorative component body 31 is provided with a through hole 33, which penetrates the first surface 31A and the second surface 31B. The through hole 33 includes a preset hole segment 331. The inner wall of the preset hole segment 331 is used to form a receiving space 33A for accommodating the camera with the camera module 60. The preset hole segment 331 includes a cylindrical hole segment 3312, a first irregular hole segment 3311A, and a second irregular hole segment 3311B. The first irregular hole segment 3311A is located between the cylindrical hole segment 3312 and the second irregular hole segment 3311B, connecting the cylindrical hole segment 3312 and the second irregular hole segment 3311B. The first irregularly shaped hole segment 3311A has two rounded inner wall sections 3311a and 3311b, and the dust-absorbing adhesive layer 32 covers the rounded inner wall sections 2311a and 2311b. In this embodiment, the first irregularly shaped hole segment 3311A is located between the cylindrical hole segment 3312 and the second irregularly shaped hole segment 3311B, providing a smooth transition. See also Figure 7 The diagram shows the structure of the through hole 33 and the dust-absorbing adhesive layer 32 as observed from the first surface 31A to the second surface 31B. In this embodiment, the second irregular hole segment 3311B is a hexagonal prism hole segment.

[0046] Understandably, the irregular-shaped hole segment can consist of a first irregular-shaped hole segment, with at least one first irregular-shaped hole segment, and the segments of the first irregular-shaped hole segment are interconnected. The irregular-shaped hole segment can also consist of a second irregular-shaped hole segment, with at least one second irregular-shaped hole segment, and the segments of the second irregular-shaped hole segment are interconnected. The irregular-shaped hole segment can also simultaneously protect both the first and second irregular-shaped hole segments, with at least one first irregular-shaped hole segment and at least one second irregular-shaped hole segment, and the segments of the first and second irregular-shaped hole segments are interconnected.

[0047] exist Figure 1 and Figure 3 In the illustrated embodiment, all segments of through holes 13 and 23 are preset segments, and the receiving space 13A formed by the camera module 40 and camera module 50 is the same as that of through hole 13, and the receiving space 23A is the same as that of through hole 23. In other embodiments, some segments of the through holes are preset segments, and the receiving space formed by the camera module is different from that of the through hole. Figure 5 In the embodiment shown, the through hole 33 further includes an assembly hole segment 332, which is connected to the preset hole segment 331. The assembly hole segment is used to assemble with the camera module 60 to form a receiving space 33A for accommodating the camera. At this time, the receiving space 33A is different from the through hole 33.

[0048] In this embodiment, the dust-absorbing adhesive layer covers the inner wall of the preset hole segment, that is, the dust-absorbing adhesive layer covers the inner wall of the irregular hole segment. This means that no matter how the irregular hole segment is designed, the inner wall of the irregular hole segment is covered with a dust-absorbing adhesive layer to ensure the adsorption effect on small foreign objects such as white spots and lint.

[0049] The decorative component can have one or more through holes, each through hole independently including a pre-defined hole segment, and each pre-defined hole segment independently including an irregularly shaped hole segment. For example, the number of through holes can be 2, 3, 4, or 5. Please refer to [link / reference]. Figure 8 , showed Figure 1 The diagram shows the structure of the camera decoration 10 as seen from the first surface 11A to the second surface 11B. The camera decoration 10 has three through holes, namely through hole 13a, through hole 13b and through hole 13c. Through hole 13a is referred to as through hole 13 above, through hole 13b is referred to as through hole 23 above, and through hole 13c is referred to as through hole 33 above.

[0050] Optionally, the camera trim also includes a protective lens. See below. Figure 9 The protective lens 15 is disposed on the decorative body 11 to seal the receiving space 13A. Optionally, an adhesive layer is also included between the protective lens 15 and the decorative body 11 to fix the protective lens 15 to the decorative body 11.

[0051] Optionally, the visible light transmittance of the dust-collecting adhesive layer is not less than 85%. Optionally, the visible light transmittance of the dust-collecting adhesive layer is 85% to 99%. For example, the visible light transmittance of the dust-collecting adhesive layer is 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99%. The high visible light transmittance of the dust-collecting adhesive layer means that when it is applied to the inner wall of the pre-defined perforated section, it has minimal impact on the light transmission effect of the through-hole.

[0052] Optionally, the adhesive strength of the dust-collecting adhesive layer is 1 N / cm to 10 N / cm. For example, the adhesive strength of the dust-collecting adhesive layer is 1 N / cm, 2 N / cm, 3 N / cm, 4 N / cm, 5 N / cm, 6 N / cm, 7 N / cm, 8 N / cm, 9 N / cm, and 10 N / cm. At the above adhesive strength, the adhesion between the dust-collecting adhesive layer and the inner wall of the preset hole segment can be guaranteed, and after drops and vibrations, the adsorbed minute residual foreign matter will not fall off the dust-collecting adhesive layer. The above adhesive strength can be obtained by testing according to GB / T 2792-2014.

[0053] Optionally, the dust-collecting adhesive layer is a cured adhesive layer. The dust-collecting adhesive layer can be cured with adhesive to achieve full coverage of the inner wall of the preset hole segment.

[0054] In today's increasingly competitive smart electronic device market, appearance quality has become one of the main factors differentiating products. This is especially true for high-end electronic devices, where users have ever-growing demands for a refined appearance. After the camera decorative component using the above-described method is assembled with the camera module, the dust-absorbing adhesive layer can autonomously adsorb movable defects within a certain range, effectively preventing the residue of tiny foreign objects such as white spots and lint, thus ensuring the high yield of the electronic device's appearance. Furthermore, it also avoids the impact of white spots, lint, and other tiny foreign objects on the product's photographic function.

[0055] The second aspect of this application provides a method for manufacturing a camera decorative part. In one embodiment, please refer to... Figure 10 The method for preparing camera decorative parts includes the following steps:

[0056] S10. Provide a decorative component body, the decorative component body having a through hole, the through hole including a preset hole segment, the inner wall of the preset hole segment being used to form an accommodating space for accommodating the camera module.

[0057] The structure of the main decorative component is described above and will not be repeated here.

[0058] S20. Apply glue to the inner wall of the preset hole segment and cover the inner wall of the preset hole segment, and cure to form a dust-collecting adhesive layer.

[0059] Optionally, before applying adhesive to the inner wall of the pre-defined hole segment, the following step is included: applying a masking film to the uncoated area of ​​the decorative component body. Applying the masking film protects the uncoated area of ​​the decorative component body.

[0060] By applying adhesive, the inner wall of the pre-designed holes can be completely covered, maximizing the adsorption area of ​​the adhesive layer and ensuring effective adsorption of small foreign objects such as white spots and lint. This method is particularly useful for pre-designed holes, including irregularly shaped ones, as it ensures complete coverage of the inner wall of these irregularly shaped holes.

[0061] Optionally, adhesive is applied to the inner wall of the preset hole segment, including the following steps: spraying the adhesive onto the inner wall of the preset hole segment. Applying adhesive to the inner wall of the preset hole segment by spraying helps prevent adhesive overflow. Furthermore, by using a CCD sensor, the spraying accuracy can be controlled to ±0.05mm, enabling the adhesive to be covered on the inner wall of a rounded corner surface with a small axial dimension, ensuring effective adhesion.

[0062] Optionally, the main resin of the adhesive includes at least one of copolymers of acrylic acid and polyurethane and copolymers of acrylate and polyurethane. It is suitable for bonding plastics (e.g., polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA)), metals, and stainless steel (SS), and exhibits excellent aging resistance, water resistance, and weather resistance, while being safe and environmentally friendly.

[0063] Optionally, the visible light transmittance of the adhesive is 10% to 70%. For example, the visible light transmittance of the adhesive is 10%, 20%, 30%, 40%, 50%, 60%, or 70%. Lower visible light transmittance of the adhesive facilitates observation of its position during application, ensuring effective coating. The adhesive in this embodiment is milky white before curing.

[0064] After applying adhesive to cover the inner wall of the receiving space, the adhesive cures to form a dust-absorbing adhesive layer. In this embodiment, after the adhesive cures, the surface of the dust-absorbing adhesive layer is smooth and sticky, capable of autonomously adsorbing movable defects within a certain range, such as white spots, lint, and other tiny foreign objects. This effectively prevents residues from affecting the appearance of the electronic device and avoids impacting its camera function. Furthermore, the visible light transmittance of the dust-absorbing adhesive layer is not less than 85%. The high visible light transmittance of the dust-absorbing adhesive layer means that when it covers the inner wall of the receiving space, it has minimal impact on the light transmission effect of the through-holes. Additionally, the adhesive strength of the dust-absorbing adhesive layer is 1 N / cm to 10 N / cm. This adhesive strength ensures the adhesion between the dust-absorbing adhesive layer and the inner wall of the receiving space, and even after drops or vibrations, the adsorbed tiny residual foreign objects will not detach from the dust-absorbing adhesive layer.

[0065] Compared to the technical barriers and resource support required to develop adsorption adhesive layers with better adsorption performance, this embodiment forms a dust-absorbing adhesive layer on the inner wall of the containment space by coating with glue, which can maximize the adsorption area of ​​the dust-absorbing adhesive layer, is easier to implement, and has a lower cost.

[0066] Understandably, after forming the adhesive layer, the process also includes applying a process film to the first and second surfaces of the camera trim to protect the first and second surfaces.

[0067] A third aspect of this application provides an electronic device. In one embodiment, the electronic device includes a display module, a circuit board, a camera trim, and a housing. The camera trim is manufactured as described above or by the manufacturing method described above.

[0068] The housing has an opening, and a camera trim piece covers the opening and is positioned on the side of the housing opposite to the display module;

[0069] The display module and housing enclose and form an accommodating space;

[0070] The circuit board is located within the enclosure and is electrically connected to the display module.

[0071] The following description is further illustrated with specific embodiments and comparative examples. Unless otherwise specified, the raw materials involved in the following specific embodiments and comparative examples are all commercially available. Unless otherwise specified, the instruments used are all commercially available. Unless otherwise specified, the processes involved are conventionally selected by those skilled in the art.

[0072] Example 1

[0073] This embodiment provides a camera decorative component and its manufacturing method, the steps of which are as follows:

[0074] supply Figure 1 After the decorative part body shown passes the IQC inspection, a masking film is attached to the non-preset hole area of ​​the decorative part body, and glue is sprayed on the inner wall of the preset hole to cover the inner wall of the preset hole. The glue is cured to form a dust-absorbing adhesive layer, thus obtaining the camera decorative part.

[0075] Based on product requirements, experiments were designed to verify the reliability of the dust-collecting adhesive layer on the camera trim, as well as to conduct drop and vibration tests on the camera trim. The results are shown in Table 1. A process film was applied to the first and second surfaces of the camera trim, and after passing inspection, it was then... Figure 1 The camera module shown was assembled, and after assembly, a white spot / hair vibration test was performed. The degree of white spot / hair detachment was recorded, and the results are shown in Table 2. After the vibration test, a reliability verification was performed again, and the results are shown in Table 2.

[0076] Table 1

[0077]

[0078] Table 2

[0079]

[0080] As shown in Table 1, the adhesion of the dust-collecting adhesive layer to the main body of the decorative part is qualified, meeting the market demand for electronic devices.

[0081] As shown in Table 2, after the camera decorative parts are assembled with the camera module, the white dots and lint adsorbed by the dust-absorbing adhesive layer do not fall off under vibration test. After vibration, the adhesion of the dust-absorbing adhesive layer on the main body of the decorative parts is still qualified, which meets the needs of the electronic equipment market.

[0082] Comparative Example 1

[0083] This comparative example provides a camera decorative part and its preparation method, which is basically the same as Example 1, except that: after the main body of the decorative part passes the IQC inspection, it is manually cleaned to obtain the camera decorative part. The camera decorative part is then assembled with the camera module, and after assembly, it is manually cleaned. After vibration testing, it is manually cleaned again.

[0084] The costs of Example 1 and Comparative Example 1 are compared, and the results are shown in Table 3.

[0085] Table 3

[0086]

[0087] As shown in Table 3, compared with the traditional method of relying on manual cleaning of small foreign matter residues, the method of spraying dust-absorbing adhesive to form a dust-absorbing adhesive layer in Example 1 can reduce manual operation, reduce leakage, and has low cost (saving more than 50% of the cost), and can ensure product yield (increasing the yield by more than 10%), and can effectively control the market quality performance of the product.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
