Description

TECHNICAL FIELD

[0001] The utility model relates to mobile phone lens technical field especially, relate to a mobile phone lens, mobile phone camera module and mobile phone. BACKGROUND

[0002] In the design process of one-inch mobile phone lens, the size difference of some lenses is large, which leads to the risk of misalignment when using a spacer to support. In order to ensure the accurate alignment and performance of the lens, the size and supporting method of the lens need to be finely adjusted and optimized.

[0003] Since one-inch mobile phone lens usually contains multiple lenses, such as CN113093367B camera lens group, and is extremely sensitive to lens spacing and alignment accuracy, the precision requirement is extremely high during the lens assembly process. This requires the use of high-precision processes and equipment during manufacturing and assembly to ensure the overall performance and image quality of the lens. SUMMARY

[0004] Therefore, the utility model discloses a mobile phone lens and mobile phone camera module. The lens L1 to L5 is sensitive to spacing, so a mica sheet is used for direct support or added. The fifth and sixth lenses are fixed by a spacer, and the sixth and seventh lenses are fixed by a spacer and glue, ensuring that the front lens does not move and solving the problem of misalignment caused by direct support.

[0005] According to one aspect of the utility model, a mobile phone lens is provided, including a lens frame, a spacing sensitive lens group arranged in order from the object side to the image side, and a sixth lens and a seventh lens. The spacing sensitive lens group includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens arranged in order from the object side to the image side.

[0006] The spacing between the fifth lens and the sixth lens is 0.39mm, and the spacing between the sixth lens and the seventh lens is 1.42mm.

[0007] The first lens, the second lens, the third lens, the fourth lens, and the fifth lens are directly supported or supported by a mica sheet on the supporting surface.

[0008] The sixth lens is separated from the fifth lens by a spacer on the object side and fixed by glue on the image side.

[0009] The seventh lens is directly supported or supported by a mica sheet on the supporting surface and fixed by a spacer and glue on the image side.

[0010] In the above technical solution, L1 to L5 lenses are sensitive to spacing, so a lens is directly supported or a Mylar sheet is added. The spacing between L5 lens and L6 lens is large, a spacer is supported, and the spacing can have certain adjustment effect on lens field curvature. The spacing between L6 lens and L7 lens is larger, and the lens size has a significant difference. If forced to support through the spacer, a large spacer is needed, and the stress misalignment is serious, but the L6-L7 spacing is relatively insensitive, so the spacer is matched with the point glue method to fix the L6 and L7 lenses. At this time, only a small spacer is needed, and the precision requirement of the spacer is low. The structure design uses two point glue processing. The lenses with similar sizes at the front end are fixed by point glue (the similar size is relative. The maximum difference of the outer diameter of the first five lenses is 0.5mm, the outer diameter of L5 and L6 is 1.05mm, and the outer diameter of L6 and L7 is 2.15mm. The point glue position is at the L6 lens, and the L6 lens is tightly matched with the second spacer and fixed by point glue). The risk of lens movement caused by misassembly of multiple parts can be avoided to a certain extent.

[0011] In some embodiments, the sixth lens is spaced from the fifth lens by a first spacer on the object side, and is fixed by point glue on the image side;

[0012] The lens frame at the second spacer installation position is provided with a plurality of first protruding portions, the first protruding portions abut against the second spacer, and the first protruding portions are filled with cured glue.

[0013] In the above technical solution, the sixth lens is spaced from the fifth lens by a first spacer on the object side, and is fixed by point glue on the image side. A plurality of first protruding portions are arranged on the lens frame at the second spacer installation position, the first protruding portions abut against the second spacer, and the first protruding portions are filled with cured glue. Thus, the precise alignment and structural stability of the lens are realized, the assembly error is reduced, the lens is protected, maintenance and replacement are facilitated, the optical performance is improved, different environmental conditions are adapted, and the stability and reliability of the lens group under various environments are ensured.

[0014] In some embodiments, the seventh lens is arranged on the lens frame by direct support on the object side, or by direct support and a Mylar sheet on the support surface, and is fixed by point glue on the image side through a third spacer;

[0015] The lens frame at the third spacer installation position is provided with a plurality of second protruding portions, the second protruding portions abut against the third spacer, and the second protruding portions are filled with cured glue.

[0016] In the above technical solution, the seventh lens is fixed on the object side by direct bearing or in combination with a Mylar sheet, providing accurate positioning and stability, and the Mylar sheet on the bearing surface can reduce friction and wear, protecting the lens surface. On the image side, the seventh lens is fixed by the third spacer ring and the point glue method. This combined fixing method not only utilizes the stability of the spacer ring, but also provides additional adhesive strength through point glue, ensuring the accuracy and long-term stability of the lens position. The second protrusions arranged on the frame abut against the third spacer ring, and the protrusions are filled with solidified glue. This design enhances the stability and durability of the overall structure, and the solidified glue filling provides additional support and shock resistance, making the entire optical system more robust and durable.

[0017] In some embodiments, the protrusions are three, and are arranged in a triangular shape around the optical axis.

[0018] In the above technical solution, the three protrusions arranged in a triangular shape provide asymmetric support points, enhancing the structural stability of the lens group, while allowing more flexible stress distribution, which helps to reduce aberrations caused by improper installation, improve optical performance, and this layout allows effective fixation in a compact space, facilitating maintenance and adapting to different environmental conditions.

[0019] In some embodiments, the frame is further provided with a base, which is an integral structure with the frame.

[0020] In the above technical solution, the frame and base are designed as an integral structure, which can reduce costs.

[0021] In some embodiments, the third lens is a glass aspherical lens, and the remaining lenses are plastic lenses.

[0022] In the above technical solution, the optical structure adopts a 1G6P configuration, in which most of the lenses are made of plastic material, and the inner diameter of the frame adopts a loose fitting method. Especially at the positions of the sixth and seventh lenses, the fixing method of the spacer ring and the point glue ensures the stability of the front end lens, avoids displacement, and solves the problem of stress misalignment caused by direct bearing of the lens, improving the stability and reliability of the overall structure.

The sixth lens L6 is fixed by a point gluing method on the image side through a second spacer 7; the seventh lens L7 is directly supported on the object side, and a fifth Mylar sheet 8 is arranged on the supporting surface, and the seventh lens L7 is arranged and fixed by a point gluing method on the image side through a third spacer 9.

[0045] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 ; the lens frame 1 at the installation position of the second spacer 7 is provided with a plurality of first protruding portions 10, which abut against the second spacer 7, and the first protruding portions 10 are filled with cured glue (grid filling area in Figure 4 ). Among them, the lens frame 1 at the installation position of the third spacer 9 is provided with a plurality of second protruding portions 11, which abut against the third spacer 9, and the second protruding portions 11 are filled with cured glue (grid filling area in Figure 4 ).
