The semi-transparent ink is disposed at the edge of the lower surface of the blue glass body. The solid double-sided optical adhesive completely covers the semi-transparent ink, and the diffusion ink completely covers the solid double-sided optical adhesive. The thickness of the semi-transparent ink is 4μm-5μm, the thickness of the solid double-sided optical adhesive is 10μm-15μm, and the thickness of the diffusion ink is 6μm-7μm.

[0005] This invention provides a camera module, which includes a lens base and a camera blue glass as described above disposed on the lens base. The lens base includes a side wall of a lower base. A circuit board is disposed at the bottom of the side wall of the lower base perpendicular to the side wall of the lower base. An inner groove is formed on the lower surface of the side wall of the lower base, which surrounds the side wall of the lower base. An adhesive layer is disposed in the inner groove.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] Please see Figure 1 The present invention provides a camera blue glass, which includes a blue glass body 1, a semi-transparent ink 2, a solid double-sided optical adhesive 3, and a diffusion ink 4, which are stacked sequentially from top to bottom. The semi-transparent ink 2 is disposed on the edge of the lower surface of the blue glass body 1. The solid double-sided optical adhesive 3 completely covers the semi-transparent ink 2, and the diffusion ink 4 completely covers the solid double-sided optical adhesive 3. The thickness of the semi-transparent ink 2 is 4μm-5μm, the thickness of the solid double-sided optical adhesive 3 is 10μm-15μm, and the thickness of the diffusion ink 4 is 6μm-7μm.

[0027] The innovation of this invention lies in adding a layer of solid double-sided optical adhesive 3 between the semi-transparent ink 2 and the diffusion ink 4 of the blue glass. This solid double-sided optical adhesive 3 can effectively prevent the interpenetration between the semi-transparent ink 2 and the diffusion ink 4, while maintaining the light transmittance of the semi-transparent ink 2. This design significantly reduces the light spots formed by the diffusion ink 4 penetrating, improving the light transmittance of the semi-transparent ink 2, thereby ensuring the appearance and performance of the product. It can also extend the service life of the blue glass, reducing the need for repair or replacement due to ink penetration. Simultaneously, it simplifies the production process, reduces the scrap rate due to ink penetration, and improves production efficiency.

[0028] Please see Figures 2 to 5This invention provides a camera module comprising a lens base 5 and a camera blue glass as described above, disposed on the lens base 5. The lens base 5 includes a side wall 6 of a lower base. A circuit board 7, perpendicularly disposed to the bottom of the side wall 6, is provided. An inner groove 61, surrounding the side wall 6, is formed on the lower surface of the side wall 6. An adhesive layer 8 is provided in the inner groove 61. The circuit board 7 is bonded to the side wall 6 of the lower base via the adhesive layer 8. In this embodiment, the adhesive layer 8 is glue. When applying the glue, care should be taken not to exceed the lower surface of the side wall 6, while ensuring the glue fills the inner groove 61. This ensures sufficient bonding area between the glue and the side wall after curing, without generating tensile force that could deform the circuit board 7. Because the inner groove 61 is coated with glue, and the glue will not overflow, the tensile force generated after curing is concentrated in the direction perpendicular to the circuit board 7, which will not cause the circuit board 7 to deform. This avoids changes in the flatness of the circuit board 7 with optical sensor caused by the oblique tensile force generated after the glue shrinks. In turn, it avoids changes in the position of the lens and optical sensor, and prevents the clarity of the central area of ​​the image captured by the camera module from not being fixed in the clearest position, thereby improving product yield, reducing product cost, and improving product competitiveness.

[0029] Furthermore, at least one venting groove 72 is provided on the inner groove 61. When the side wall 6 of the lower base is pressed onto the adhesive, the air in the inner groove 61 can be expelled, allowing the adhesive to fill the space of the inner groove 61 smoothly and preventing the formation of air bubbles.

[0030] Furthermore, the lower base has four side walls 6, which are connected in pairs.

[0031] Furthermore, each lower base has three exhaust slots 72 on its side wall 6 to allow air to escape.

[0032] Furthermore, the adhesive layer 8 is AA glue.

[0033] Furthermore, two staggered reinforcing plates 9 are provided on both sides of the circuit board 7. In traditional circuit board 7 designs, reinforcing plates 9 are usually not provided or are placed in the same position with the same width. This causes the pressure applied when inserting or removing the circuit board 7 to be concentrated on the same straight line, resulting in micro-breaks in the circuit board 7. The circuit board 7 provided by this invention has two reinforcing plates 9 located on both sides of the connection and staggered from each other. When the circuit board 7 is pulled out, the pressure applied to the circuit board 7 by the two reinforcing plates 9 is not on the same line segment, and the stress will not be concentrated on the same straight line when bending. This avoids stress concentration and the problem of easy micro-breaks in the circuit at the interface end, thereby improving product yield.

[0034] Furthermore, the two staggered reinforcing plates 9 referred to in this invention can be located at two different positions; alternatively, they can have the same center point but different widths. The key is to ensure that the stress from bending the two reinforcing plates 9 is not concentrated on the same straight line. This avoids stress concentration and the problem of minor breaks in the wiring at the interface, thus improving product yield. In this embodiment, the reinforcing plates 9 include a first reinforcing plate 9 and a second reinforcing plate 9. Each reinforcing plate 9 has a different width, and their center points are on the same horizontal line, so that the edges of the reinforcing plates 9 are staggered and not concentrated on the same straight line.

[0035] Furthermore, the reinforcing plate 9 is made of FR4, PI, or stainless steel. In other embodiments, if the circuit board 7 generates a large amount of heat, a heat dissipation material with better heat dissipation effect, such as aluminum foil reinforcing plate 9, can also be used.

[0036] Furthermore, the outer surfaces of both the first reinforcing plate 9 and the second reinforcing plate 9 are provided with a surface treatment layer to increase surface roughness, so as to improve the friction between the operator and the first reinforcing plate 9 and the second reinforcing plate 9, making the circuit board 7 easier to pull out.

[0037] Furthermore, the surface treatment layer has diamond knurling on the outer surfaces of both the first reinforcing plate 9 and the second reinforcing plate 9, so that the circuit board 7 can be pulled out more easily, reducing the risk of circuit breakage of the circuit board 7.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.

Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
