Referring to fig. 15 to 17, fig. 15 is a schematic flow chart of a method for manufacturing a decorative piece for a camera according to an embodiment of the present application, fig. 16 is a schematic sub-flow chart of step S01 shown in fig. 15, and fig. 17 is a schematic sub-flow chart of step S03 shown in fig. 15. The embodiment of the application further provides a manufacturing method of the camera decorating part 10, which can comprise the following steps:

step S01, providing a first lens 111 and a second lens 112, and stacking the first lens 111 and the second lens 112 to form a lens assembly 11, wherein the area of the first lens 111 is smaller than the area of the second lens 112, and the first lens 111 is located within the range of the second lens 112.

In this step, the first lens 111 is a sapphire lens, and the second lens 112 is a colorless transparent lens. The sapphire lens has the advantages of chemical corrosion resistance, high temperature resistance, good heat conduction, high hardness, infrared transmission and good chemical stability, can effectively resist external impact, and also has good optical performance.

Step S01 includes the steps of:

step S11: the first lens 111 and the second lens 112 are subjected to shape processing, polishing and hardening in sequence.

First, a sapphire substrate and a glass substrate are respectively taken and processed into a first lens 111 and a second lens 112 with corresponding sizes and shapes by adopting a laser cutting mode. The shapes of the first lens 111 and the second lens 112 can be processed by a middle sheet process, and one plate (dozens of pieces are processed on one plate at the same time) is formed at one time, so that the processing efficiency can be greatly improved, and the cost is greatly reduced; and the laser processing precision is higher, and the dimensional tolerance is +/-0.03 mm, so that the precision requirements of the first lens 111 and the second lens 112 are met. In the present embodiment, the first lens 111 has a flat cylindrical shape, and the second lens 112 has a flat cylindrical shape, so that the first lens 111 and the second lens 112 have stable structures and beautiful appearances, and are easy to process.

Next, the first lens 111 and the second lens 112 are polished to be smooth. Specifically, the first lens 111 and the second lens 112 may be chemically polished, that is, the first lens 111 and the second lens 112 are put into a hydrofluoric acid solution, and under the chemical attack of hydrofluoric acid, the rugged areas of the first lens 111 and the second lens 112 are selectively dissolved to eliminate grinding marks and to smooth the surface of the first lens 111 and the second lens 112. Wherein the chemical polishing has the advantages of simple equipment, easy operation and higher polishing precision.

Next, the first lens 111 and the second lens 112 are hardened to increase the hardness of the first lens 111 and the second lens 112. Specifically, a thermal treatment process may be used to form a compressive stress layer on the surfaces of the first lens 111 and the second lens 112. When the first lens 111 and the second lens 112 receive an external force, the compressive stress layer can offset a portion of the tensile stress, so as to prevent the first lens 111 and the second lens 112 from being broken.

Step S12: the second lens 112 is shaded to form a window area 1130, wherein the window area 1130 can be orthographically projected within the first lens 111.

It can be understood that if the first lens 111 is smaller than the size of the lens of the camera module 300, the lighting of the camera module 300 is affected; the size of the first lens 111 smaller than the lens of the camera module 300 is equal to the size of the lens of the camera module 300, the requirement on the processing precision of the first lens 111 is high, and the practicability is poor, so that the size of the first lens 111 is usually far larger than the size of the lens of the camera module 300. In order to prevent the excessive light from entering the lens of the camera module 300, the lens assembly 11 needs to be shielded to control the light entering the camera module 300. Specifically, a light shielding layer 113 is formed on the second lens 112 by using a screen printing ink manner, and a window area 1130 is disposed on the light shielding layer 113, wherein the area of the window area 1130 corresponds to the area of the mirror surface of the camera module 300, and the window area 1130 is located within the range of the first lens 111, so that light can sufficiently pass through the window area 1130 and enter the camera module 300.

Specifically, the first light-shielding layer 1131 and the second light-shielding layer 1132 may be formed by respectively performing ink printing on two opposite side surfaces of the second lens 112 by using a screen printing ink method. The first light shielding layer 1131 is provided with a first through hole 1133, the second light shielding layer 1132 is provided with a second through hole 1134, the first through hole 1133 is disposed corresponding to the second through hole 1134, and the window area 1130 is formed by the first through hole 1133 and the second through hole 1134 in a matching manner.

Step S13: performing anti-reflection treatment on the first lens 111 and the second lens 112.

Specifically, AR (Anti-Reflection, increased light transmission) coating is performed on the first lens 111 and the second lens 112 respectively to increase the transmittance of the first lens 111 and the second lens 112 and reduce the Reflection thereof.

Step S14: the first lens 111 and the second lens 112 are connected and fixed.

Specifically, the Optical Cement (OCA) has the advantages of being colorless and transparent, having a light transmittance of 90% or more, having a good cementing strength, being curable at room temperature or at intermediate temperature, and having a small curing shrinkage, and the like, so that the first lens 111 can be fixedly connected through the optical cement, thereby ensuring the reliability of connection between the first lens 111 and the second lens 112, and also ensuring the light transmittance of the lens assembly 11.

In this embodiment, the first lens 111 and the second lens 112 are both flat cylindrical, and the first lens 111 and the second lens 112 are coaxially disposed and form a regular annular step structure.

Step S02, providing a base material of the decorative plate 12, and forming the decorative plate 12 by forming a through hole 120 on the base material of the decorative plate 12, wherein the first lens 111 can be clamped and fixed by the through hole 120.

Specifically, the base material of the decorative plate 12 may be one of ceramic, metal, glass, and plastic, and in this embodiment, the base material of the decorative plate 12 may be made of ceramic.

In this embodiment, the through hole 120 is formed by a laser cutting process, so that the through hole 120 has a smaller tolerance to better fit the lens assembly 11. The through hole 120 includes a first accommodating hole 1201 and a second accommodating hole 1202, wherein the first accommodating hole 1201 is located on the first surface 121, and the second accommodating hole 1202 is located on the second surface 122. The first lens 111 can be fixed in the first accommodating hole 1201 in a clamping manner, the second lens 112 can be fixed in the second accommodating hole 1202 in a clamping manner, and the surface of the second lens 112, which is connected with the first lens 111, abuts against the bottom surface of the second accommodating hole 1202, so that on one hand, the lens assembly 11 is accurately positioned by the first lens 111, the second lens 112 and the decorative plate 12, and on the other hand, the first lens 111 is prevented from protruding out of the outer surface 212 along the thickness direction of the decorative plate 12.

It can be understood that the sum of the thicknesses of the first lens 111 and the second lens 112 is much smaller than the thickness of the decoration plate 12, wherein the thickness of the first lens 111 corresponds to the depth of the first accommodation hole 1201, the thickness of the second lens 112 is smaller than the depth of the second accommodation hole 1202, and the camera module 300 can be partially accommodated in the second accommodation hole 1202 to fully utilize the space of the camera decoration 10.

In other embodiments, the first lens 111 can be held and fixed in the through hole 120, so that the lens assembly 11 can be precisely positioned with the decorative plate 12 through the first lens 111; the second lens 112 is connected to the surface of the first lens 111, and the second lens 112 abuts against the second surface 122, so as to prevent the first lens 111 from protruding from the outer surface 212 along the thickness direction of the decoration plate 12.

In step S03, the lens assembly 11 is accommodated and fixed in the through hole 120.

In this step, the lens assembly 11 is fixedly connected to the decoration, and the camera decoration 10 is integrally assembled.

Specifically, step S03 may include the steps of:

in step S31, the inner wall of the through hole 120 is dispensed.

That is, the fixing glue is uniformly applied to the inner surface 211 of the through-hole 120, so that it can sufficiently contact the edges of the first and

second lenses

111 and 112 and fix the first and

second lenses

111 and 112.

In step S32, the lens assembly 11 is accommodated in the through hole 120 and is fixedly connected to the inner wall of the through hole 120.

Specifically, the lens assembly 11 is installed in the through hole 120 from the side of the second surface 122 of the decoration, wherein the first lens 111 is held and fixed in the first accommodating hole 1201, the second lens 112 is held and fixed in the second accommodating hole 1202, and the surface of the second lens 112 connected with the first lens 111 abuts against the bottom surface of the second accommodating hole 1202, so as to prevent the first lens 111 from protruding out of the outer surface 212 along the thickness direction of the decoration plate 12. The first lens 111 and the second lens 112 are fixedly connected to the decorative plate 12 by fixing glue.

And step S33, polishing the decorative plate 12 and the lens assembly 11.

Firstly, the decorative plate 12 and the lens assembly 11 which are fixedly connected are placed in rolling polishing powder, and the surfaces of the decorative plate 12 and the lens assembly 11 are roughly polished through rolling friction of the polishing powder.

Secondly, the first surface 121 of the decorative plate 12 and the surface of the first lens 111 departing from the second lens 112 are polished by a flat grinding process, so that the first surface 121 and the surface of the first lens 111 departing from the second lens 112 are flush, and no gap exists between the first lens 111 and the decorative plate 12, thereby improving the consistency of the decorative plate 12 and the first lens 111.

Then, the first surface 121 of the decorative plate 12 and the surface of the first lens 111 departing from the second lens 112 are subjected to finish polishing operation, and finally the decorative plate 12 and the first lens 111 exhibit an integration effect.

In this embodiment, the decorative plate 12 is made of ceramic, and the first lens 111 is made of sapphire. Because the hardness of the ceramic material is similar to that of sapphire glass, the decorative plate 12 and the lens assembly 11 can meet various processing requirements in the polishing process. When the first lens 111 is made of ordinary glass, the hardness of the ceramic is much higher than that of the ordinary glass, so that the first lens 111 is easily broken during polishing of the decorative plate 12 and the lens assembly 11, and the reliability of the lens assembly 11 is affected.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
