Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The texture effect in the camera lens of the electronic device is usually manufactured by using a GDM process (i.e. printing ink directly on the surface of glass). Specifically, the texture (generally, CD texture) on the surface of the mold can be directly transferred to the surface of the lens substrate by UV glue by a UV transfer printing method on the surface of the lens substrate formed of glass, so as to form a texture layer; and finally, removing the brightness enhancement film in a window area (namely an area corresponding to the light incident surface of the camera) of the lens substrate by deplating, so that the camera lens has a glittering texture effect and the shooting of the camera is not influenced.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

In the research of the applicant, the above method has found that when the coating layer on the window area of the lens substrate is removed by deplating, the coating layer is usually simpler in composition so as to facilitate deplating in order to avoid the deplating agent from ablating the ink layer on the lens substrate and causing damage to the lens substrate in the window area. In addition, the thickness of the coating layer is smaller and is generally lower than 150nm, so that the coating layer has a single color and a single luster effect.

Therefore, if a new camera lens can be provided, the related technical problems caused by deplating do not exist, and the texture color effect with rich color can be realized, so that the technical problems can be solved to a great extent.

Accordingly, the embodiments of the present application provide a camera lens to solve the above technical problems.

Referring to fig. 1, fig. 1 is a schematic exploded view of a camera lens 100 according to some embodiments of the present disclosure, where the camera lens 100 generally includes a substrate 10 and a coloring layer 20 stacked on each other. The substrate 10 is made of a transparent material, so that light can penetrate through the substrate 10 to irradiate the camera, and the shooting function of the camera is realized. For example, the substrate 10 may be made of transparent glass or transparent resin.

Specifically, the substrate 10 has a window area 11 and a texture area 12 disposed around the window area 11. The texture area 12 is used for forming the first texture pattern 121, so that the camera lens can have appearance effects such as textures intuitively. In the embodiment of the present application, the first texture pattern 121 is disposed on a surface of the substrate 10 facing away from the colored layer 20.

Further, the window area 11 is an area corresponding to the light incident surface of the camera, and is used for light to pass through to realize the shooting function of the camera, i.e. the window area 11 is generally light-permeable. The texture area 12 is disposed around the window area 11, and the texture effect such as the first texture pattern 121 can be displayed in the texture area 12, thereby improving the appearance effect of the camera. Generally, the window area 11 and the texture area 12 may have a certain distance therebetween, and black shielding ink or the like may be disposed in the area between the window area 11 and the texture area 12 to prevent the light reflected by the colored layer 20 and other appearance layers from affecting the shooting effect of the camera.

In the embodiment of the present application, the substrate 10 includes a first surface 101 and a second surface 102 that are opposite to each other, where the first surface 101 is a surface of the substrate 10 away from the camera, and the second surface 102 is a surface of the substrate 10 close to the camera. Further, the first side 101 of the substrate 10 is formed with a first texture pattern 121. It is understood that the first texture pattern 121 may be formed on the first side 101 of the substrate 10 by a patterning process. For example, the patterned first texture pattern 121 may be formed on the first surface 101 of the substrate 10 by etching, CNC machining (computer numerical control precision machining), or the like.

Further, the first texture pattern 121 is concavely formed in a direction toward the second side 102 along the first side 101 of the substrate 10, that is, the first side 101 of the substrate 10 is concavely formed in a direction F as shown in fig. 2 to form the first texture pattern 121. It is understood that the recesses may be formed by patterning the first side 101 of the substrate 10, for example, by etching to form a recess pattern on the first side 101 of the substrate 10 as the first texture pattern 121.

According to the embodiment of the application, the first texture pattern 121 is formed on the first surface 101 of the substrate 10, so that the risk of texture separation is avoided, the reliability is good, defects such as texture deviation and glue and wire breakage are not prone to occurring, and the overall yield of the process is high. The colored layer 20 is disposed on the second surface 102 of the substrate 10 and forms a second texture pattern 212, and the second texture pattern 212 presents its own color to present a color texture effect on the appearance of the camera lens, i.e., no additional coating is required to provide the camera lens with a color appearance effect.

Further, the second texture pattern 121 is disposed corresponding to the first texture pattern 121, and the orthogonal projection of the second texture pattern 121 on the substrate 10 covers the first texture pattern 121, so that the first texture pattern 121 can display a color texture effect, and the appearance expression of the camera lens is improved.

The camera lens provided by the embodiment of the application forms the first texture pattern and the second texture pattern on the two sides of the substrate respectively, the first texture pattern is good in reliability, gaps where textures are separated do not exist, the second texture pattern shows the color of the second texture pattern, so that the first texture pattern can present a color texture effect, and the appearance expressive force of the camera lens is improved. In addition, the structural arrangement of a coating layer is eliminated, so that the risk caused by deplating can be avoided, the production process of the camera lens is simplified, the yield is improved, and the cost can be further reduced.

Wherein the shape of the second texture pattern 212 is adapted to the shape of the first texture pattern 121. For example, the first texture pattern 121 and the second texture pattern 212 have adapted pattern shapes, i.e., the shape and size of the first texture pattern 121 and the second texture pattern 212 may be substantially identical. In some embodiments of the present application, the first texture pattern 121 and the second texture pattern 212 may be one or more of circular, elliptical, and polygonal shapes with equal size, that is, the orthographic projection of the second texture pattern 212 on the substrate 10 covers the first texture pattern 121.

As shown in fig. 1, the first texture pattern 121 and the second texture pattern 212 may have a circular shape. Of course, in other embodiments, please refer to fig. 3, fig. 3 is a schematic structural diagram of the camera lens 100 according to other embodiments of the present application, wherein the first texture pattern 121 and the second texture pattern 212 may be rectangular.

It is understood that, as shown in fig. 1 and 2, the colored layer 20 may be used only to form the second texture pattern 212, i.e., the second side 102 of the substrate 10 is provided with the second texture pattern 212 corresponding to the first texture pattern 121. In other words, the second texture pattern 212 constitutes the entire structure of the colored layer 20.

Of course, in other embodiments, the colored layer 20 can be used to form not only the second texture pattern 212, but also other texture patterns. As shown in fig. 4, fig. 4 is a schematic structural diagram of a camera lens in other embodiments of the present application, the colored layer 20 may be further used to form a third texture pattern 213, and the third texture pattern 213 shows its own texture color, so that the appearance of the camera lens presents a variety of appearances. The size and shape of the third texture pattern 213 may be the same as or different from the size and shape of the second texture pattern 212, respectively.

In other words, the colored layer 20 may cover a part of the second surface 102 of the substrate 10, or completely cover the second surface 102 of the substrate 10, which is not particularly limited in the embodiment of the present application. It should be understood that the second texture pattern 212 is disposed corresponding to the first texture pattern 121, and an orthogonal projection of the second texture pattern 212 onto the substrate 10 covers the first texture pattern 121.

Specifically, referring to fig. 1 and fig. 4 again, the coloring layer 20 is provided with a first hollow area 203, and an orthographic projection of the first hollow area 203 on the substrate 10 covers the window area 11, so as to prevent the coloring layer 20 from shielding the window area 11 and further affecting the shooting effect of the camera. The colored layer 20 is generally made of a light-impermeable material, and may be made of ink or resin paint, for example.

Further, the first texture patterns 121 having various shapes are formed on the first surface 101 of the substrate 10 by etching, CNC machining, etc., and the first texture patterns 121 may have ultra-fine line widths and line distances. The applicant has found through experiments that the line width and the line distance of the first texture pattern 121 formed in the above manner can be as small as 0.01 mm. In the embodiment of the present application, the line width of the first texture pattern 121 may be 0.01 to 0.05mm according to the actual appearance requirement. For example, in some embodiments of the present application, the line width of the first texture pattern 121 may be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05 mm. Similarly, the line pitch of the first texture pattern 121 may be 0.01 to 0.05 mm. For example, in some embodiments of the present application, the first texture pattern 121 may have a pitch of 0.01mm, 0.02mm, 0.03mm, 0.04mm, and 0.05 mm.

In some embodiments of the present application, the material of the second texture pattern 212 is colored ink or colored colloid, so that the second texture pattern 212 can present a colorful texture pattern. For example, a colloid or ink having at least one of various colors such as blue, red, gold, pink, green, black, white, etc. may be used, and the second texture pattern 212 may be formed so that the camera lens may exhibit a rich and vivid color texture effect.

Specifically, the colored colloid includes glue and nano color paste, that is, the colored colloid is generally prepared by mixing the glue and the nano color paste, and the color of the nano color paste is adjusted according to the required color, and then the colored colloid is prepared by mixing the nano color paste and the glue according to a certain proportion. The nano color paste is generally prepared by uniformly mixing a colored nano toner and a solvent. Wherein, the solvent can be water or other solvents.

For example, when the nanometer color paste of the Tuhaojin color is needed, yellow toner, red toner, blue toner and a solvent can be mixed to prepare the nanometer color paste of the Tuhaojin color. When the rose-gold-color nano-color paste is needed, the yellow toner, the purple toner and the solvent can be mixed to prepare the rose-gold-color nano-color paste. Of course, for the nano color pastes of other colors, the nano toner of the corresponding color can be prepared according to the specific color requirement, which is not always mentioned in the embodiment of the present application.

Preferably, in the embodiment of the present application, the colored colloid is preferably prepared by using an ultraviolet light curing adhesive and a nano color paste.

Further, the second texture pattern 212 can have a colorful color effect by introducing the nano color paste into the ink to form the colored ink, and the second texture pattern 212 can show a colorful color texture effect when being matched with the first texture pattern 121.

Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

The masking layer 30 is disposed on a side of the colored layer 20 away from the substrate 10, that is, the colored layer 20 is disposed between the substrate 10 and the masking layer 30.

Specifically, the masking layer 30 is made of opaque material, for example, the masking layer 30 may be made of ink or resin paint to perform a masking function. In some embodiments of the present application, the covering layer 30 is made of black ink, so that when the camera lens 100 is used in an electronic device, the covering layer 30 can shield devices inside the electronic device, and the usability of the lens is further improved.

Further, the cover layer 30 is provided with a second hollow-out area 301, and an orthographic projection of the second hollow-out area 301 on the substrate 10 covers the window area 11, that is, a part of the orthographic projection of the cover layer 30 on the substrate 10 covers a boundary area between the window area 11 and the texture area 12. Meanwhile, the light transmittance of the covering layer 30 basically does not exceed 1%, so that the covering layer 30 has a good shading effect, the shooting quality can be prevented from being influenced due to light reflection, texture patterns can be better exposed, and the appearance effect of the camera lens is enriched.

Referring to fig. 7, fig. 7 is a schematic partial sectional view of the camera lens along the direction B-B in the embodiment of fig. 6, and the cover layer 30 covers the second texture pattern 212 and the second surface 102 of the substrate 10 simultaneously to protect the second texture pattern 212.

For example, the masking layer 30 may be formed by printing a masking ink, such as a black ink, so that the masking layer 30 may have a better light shielding effect. It is to be understood that the substrate 10 and the colored layer 20 in the present embodiment can refer to the detailed description in the foregoing embodiments.

The camera lens that this application embodiment provided sets up the cover layer through the one side that deviates from the base plate at the dyed layer, not only can protect second texture pattern, can also shield electronic equipment inner part device to promote the outward appearance expressive force of camera lens.

In addition, the embodiment of the application also provides a manufacturing method of the camera lens, and the manufacturing method can be used for manufacturing the camera lens in the embodiment. Specifically, referring to fig. 8, fig. 8 is a schematic flow chart of a manufacturing method of a camera lens according to some embodiments of the present application, the manufacturing method substantially including the following steps:

s801, providing a substrate.

In this step, the substrate may have a window area and a texture area surrounding the window area. Specifically, the substrate is made of transparent materials, so that light can penetrate through the substrate to irradiate the camera, and the shooting function of the camera is achieved. For example, the substrate may be made of transparent glass or transparent resin. Further, the substrate may have a size and shape that may be related to the size and arrangement of cameras used in the electronic device.

For example, the substrate may be prepared by: firstly, cutting a large glass plate, namely cutting (for example, laser cutting) the large glass plate to form a certain size and shape; etching and thinning the cut small glass plate, namely etching the cut small glass plate by using hydrofluoric acid, wherein the glass plate can be thinned to a proper thickness by etching a single surface of the hydrofluoric acid, and then a chamfer can be formed by laser cutting; and finally, chemically strengthening the glass plate, namely cleaning the etched small glass plate, putting the small glass plate into a potassium nitrate solution, and strengthening the glass twice at 300-500 ℃ to strengthen the strength of the glass plate to form the substrate.

Further, the base plate includes first face and the second face of carrying back on the back the body and setting up, and first face is the one side that the camera was kept away from to the base plate, and the second face is the one side that the base plate is close to the camera.

S802, forming a first texture pattern on the first surface of the substrate.

In this step, a first texture pattern may be formed on the first surface of the substrate by a patterning process. For example, the patterned first texture pattern may be formed on the first side of the substrate by a patternable processing means such as etching, CNC or the like.

In the embodiment of the present application, the stamp, i.e., the first texture pattern, may be formed on the first side of the substrate by etching. The thickness and shape of the lines of the first texture pattern can be further realized by controlling the process parameters of etching, namely, the texture patterns with different thicknesses and different shapes can be realized. Of course, in other embodiments, the first textured pattern may be formed directly on the first side of the substrate by way of CNC machining. For example, a first texture pattern is formed by a tool that imprints the substrate with CNC machining by feeding the machining on a first side of the substrate. The first texture pattern formed in the above manner may have an ultra-fine line width and line pitch.

In the embodiment of the present application, the line width of the first texture pattern may be 0.01 to 0.05mm according to the actual appearance requirement. For example, in the embodiment of the present application, the line width of the first texture pattern may be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05 mm. Similarly, the line pitch of the first texture pattern may be 0.01 to 0.05 mm. For example, in some embodiments of the present application, the first texture pattern may have a pitch of 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05 mm.

And S803, forming a coloring layer on the second surface of the substrate.

In this step, the colored layer is typically made of colored glue or colored ink, and may be made of colored ink or colored UV glue, for example, to set off the first texture pattern so that the camera lens may exhibit a colored texture effect. In the embodiment of the application, the coloring layer can be directly formed on the surface of the substrate through processes such as spraying, silk-screen printing, transfer printing or 3D printing.

Further, the coloring layer is used for forming a second texture pattern, and the orthographic projection of the second texture pattern on the substrate covers the first texture pattern, so that the color effect of the second texture pattern can support the color texture effect of the first texture pattern. In other words, the second texture pattern and the first texture pattern have a matched pattern shape, i.e. the shape and size of the second texture pattern and the first texture pattern may be substantially identical. For example, the second texture pattern and the first texture pattern may be one or more of circular, elliptical, polygonal, and the like with equal size.

Specifically, step S803 further includes: the second texture pattern can be directly formed on the second surface of the substrate through processes such as spraying, silk-screen printing, transfer printing or 3D printing. For example, the texture of the mold surface may be transferred to the second surface of the substrate by UV glue directly on the second surface of the substrate by a UV transfer method, so as to form a second texture pattern.

The camera lens manufacturing method provided by the embodiment of the application forms the first texture patterns and the second texture patterns on two sides of the substrate respectively, the first texture patterns are good in reliability, gaps where textures are separated do not exist, the second texture patterns are made of materials with colors, the camera lens can show rich and bright colors by the camera lens manufacturing method, and then the camera lens is improved in appearance expressive force by backing out the first texture patterns to show rich and bright color texture effects.

Referring to fig. 9, fig. 9 is a schematic flow chart illustrating a method for manufacturing a lens of a camera lens according to another embodiment of the present disclosure, the method generally includes the following steps:

s901, providing a substrate, which can refer to step S801 in the foregoing embodiment.

S902, forming a first texture pattern on the first side of the substrate, which can refer to step S802 in the previous embodiment.

And S903 forming a coloring layer on the second surface of the substrate. Wherein, the coloring layer is used for forming a second texture pattern. This step may refer to step S803 in the foregoing embodiment.

And S904, forming a covering layer on one side of the coloring layer, which is far away from the substrate.

In this step, the masking layer may be made of an opaque material, for example, the masking layer may be made of ink or resin paint to perform a masking function. In some embodiments of the present application, the covering layer is made of black ink, so that when the camera lens is used in an electronic device, the covering layer can cover devices inside the electronic device, and the usability of the lens is further improved. The covering layer covers the second texture patterns and the second surface of the substrate, so that the second texture patterns and the second surface of the substrate are comprehensively protected on one side, close to the camera, of the camera lens.

For example, the masking layer may be formed on the side of the colored layer away from the substrate by spraying, silk-screening, or 3D printing.
