Description

Technical Field

[0001] The invention relates to the field of electronic equipment parts processing, and in particular to a lens decorative cover manufacturing method and a lens decorative cover. Background Art

[0002] With the increasing development of electronic devices such as mobile phones and tablets, as one of the key components to enhance the intelligence and interactivity of electronic devices, the lens assembly has gradually evolved from a single lens to multiple lenses. For example, the lens assembly can be a single wide-angle lens, macro lens, telephoto lens, zoom lens, etc. combined together to provide multi-functional needs for shooting different objects in different occasions, striving to maximize the user experience.

[0003] Multiple lenses can be arranged in an array such as a ring, triangle, or rectangle on the housing of the electronic device. Compared with a single lens, since multiple lenses have spaces between them, these spaces between them expose the inner housing of the electronic device to the outside, which affects the overall aesthetic appearance of the device. In order to beautify the appearance of the electronic device while ensuring the integrity and functionality of the lens assembly, it is necessary to provide a lens decorative cover that is coordinated with the overall appearance of the electronic device. The lens decorative cover not only serves as a decorative element between the lens and the appearance of the electronic device, but also serves as a connecting bridge, connecting the transparent cover to the lens decorative cover instead of directly connecting it to the inner housing of the electronic device, thereby improving the convenience of connection.

[0004] In the past, the lens decorative cover is often an integral block structure, and its surface color depends on the color of the raw material. Usually, in order to ensure the connection strength between the lens decorative cover and the inner shell, and to ensure the strength and support performance of the lens decorative cover itself, the lens decorative cover is made of high-rigidity materials such as stainless steel. For lens decorative covers made of such materials, the commonly used technical means are to grind its surface into a frosted texture, or to smooth its surface to make it more delicate and smooth to reduce the abruptness of the lens decorative cover, or to cover the outer surface of the decorative cover with a layer of black lens cover (such as a glass cover or a plastic cover to cover its original color). However, these surface treatment technologies make the lens decorative cover appear too monotonous, and these surface technologies take a long time to process and are complicated. On the other hand, the integrated lens decorative cover makes it impossible to improve its surface visual effect. Summary of the invention

[0024] Based on the plurality of reference grooves, the assembly groove is processed so that the groove bottom surface of the assembly groove is lower than the first surface of the blank, and the assembly groove is concentrically surrounded by the outer periphery of the inner hole processing area.

[0025] Furthermore, the step of performing inner hole processing based on the distribution area of ​​the lens assembly includes the following sub-steps:

[0026] Using a second surface of the blank opposite to the first surface as a processing surface and an outer periphery of the inner hole processing area as a reference, processing an inner edge seam located inside the outer periphery and having a matching shape;

[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0048] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0050] See also Figure 1a and Figure 1b , Figure 1a and Figure 1bThe structural schematic diagram of the decorative cover body after being processed and formed by the manufacturing method of the lens decorative cover of the present invention is shown as an example. The lens decorative cover after being processed and formed by the present invention includes a decorative cover body 100 and a decorative back plate (not shown) combined with the first surface 100a of the decorative cover body 100 (in the assembly groove described below). The decorative back plate can be configured according to the appearance color, pattern and / or material of different electronic devices. For example, in some embodiments, the back wall surface (a side wall away from the display screen) of the electronic device is configured as a cortical surface covered with a cortical layer, and the back plate can be configured as a cortical back plate that matches the cortical surface or a material that enhances the texture or beauty after being combined with the cortical surface. For example, in some embodiments, in order to enhance the sense of luxury or texture, the back plate can be made of glass or steel corresponding to the color of the appearance. For another example, in some embodiments, in order to reduce the weight of the electronic device, the back plate provided can be a lightweight back plate made of a lightweight material, etc. By adopting the lens decorative cover manufacturing method shown in the present invention, various variations of lens decorative covers can be configured for different models of electronic devices. Compared with the traditional method of using only a whole lens decorative cover, by processing the lens decorative cover into a combination of a decorative cover body 100 and a decorative back panel, it has wider adaptability and stronger personalization, and can better meet the needs of the existing market.

[0051] by Figure 1a and Figure 1b As an example, the decorative cover body 100 has an inner hole 114 penetrating along its thickness direction and an assembly groove 113 formed on its first surface 100a and arranged around the inner hole 114, and a plurality of assembly holes 115 penetrating along the thickness direction of the assembly cover body 100 are processed in the assembly groove 113, and the decorative back plate is installed in the assembly groove 115. Specifically, the decorative cover body 100 includes a first decorative area 110 adapted to the distribution area of ​​the lens assembly and a second decorative area 120 integrally connected to the first decorative area 110 and used to be embedded in the back wall of the electronic device along the width direction of the electronic device, and the edge of the second decorative area 120 covers at least part of the side wall of the electronic device. The shape of the first decorative area 110 is adapted to the distribution area of ​​the lens assembly. For example, in some embodiments, the lens assembly includes four arranged in a rectangular array, and the first decorative area 110 can be configured as a circular decorative area, a polygonal decorative area, etc., whose size is larger than the size of the distribution area of ​​the lens assembly.

[0052] The first decorative area 110 includes a plane area 111 and a side area 112 formed on the periphery of the plane area 111. The side area 112 can be configured as a curved surface with a certain curvature (the curved surface can be processed by CNC processing equipment described below), and the side area 112 forms a certain angle with the plane area 111, such as an obtuse angle greater than 90 degrees, so that the upper end of the side area 112 (the end connected to the plane area 111) is closer to the center of the plane area 111, and the lower end is farther away from the center of the plane area 111. When the decorative cover body 100 is assembled on an electronic device, the plane of the plane area 111 is parallel to the back wall of the electronic device, and the side area 112 forms a corresponding angle with the back wall of the electronic device.

[0053] The second decorative area 120 is integrally connected to one side of the first decorative area 110. The end of the second decorative area 120 connected to the first decorative area 110 is defined as the first end, the end away from the first decorative area 110 is defined as the second end 121, and the two side edges connected between the first end and the second end 121 are defined as the first side edge 122 and the second side edge 123. The distance between the first side edge 122 and the second side edge 123 is adapted to (e.g., consistent with) the size of the first decorative area 110 in the corresponding direction. The side surface of the lens decorative cover facing outward (away from the inside of the electronic device) in the assembled state is defined as the first surface 100a, and the side surface of the lens decorative cover facing inward (toward the inside of the electronic device) in the assembled state is defined as the second surface 100b (the second surface 100b is opposite to the first surface 100a). The second end 121 of the second decorative area 120 can be configured as a curved end that bends toward the second surface 100b, and the curved end is used to be embedded in at least a part of a side wall of the electronic device when assembled with a corresponding electronic device. For example, when the decoration cover body 100 is assembled on the back wall of the electronic device, the second decoration area 120 extends along the width direction of the electronic device toward one side wall of the electronic device, and the second end 121 of the second decoration area 120 is embedded in the side wall.

[0054] Taking the circular decorative area as an example, a mounting groove 113 with a circular outer wall is formed in the plane area 111, and the mounting groove 113 is opened from the first surface 100a of the plane area 111 to the second surface 100b. A concentric inner hole 114 is formed in the mounting groove 113. On the projection plane parallel to the plane area 111, the shape of the inner hole 114 is irregular, which is configured according to the distribution area of ​​the camera. For example, in this embodiment, the hole wall of the inner hole 114 has four arc walls 114a distributed in an outward arc, and the curvature and arc length of each arc wall 114a may be different. Each adjacent two arc walls 114a are separated by a convex portion 114b protruding inward (toward the center of the inner hole 114). Three hole positions (assembly holes 115) are distributed at two of the convex portions 114b, and at least one hole position is provided at the other two convex portions 114b. At least part of the holes are used as riveting holes for riveting rivets, and the remaining part of the holes can be used as internal screw holes. The riveting holes and internal screw holes are used to cooperate with corresponding rivets and screws to assemble the decorative cover body 100.

[0055] See also Figure 2 , Figure 2 1 is a flow chart of an embodiment of a method for manufacturing a decorative lens cover of the present invention. The method for manufacturing a decorative lens cover shown includes the following steps:

[0056] S110 , providing a blank 200 .

[0057] See also Figure 2a and Figure 2b The blank 200 has a first side surface 200a and a second side surface 200b opposite thereto. The blank 200 can be made of stainless steel as a raw material and forged by a forging process. When forging the blank 200, a through groove 201 located at the center of the blank 200 and a plurality of positioning holes 202 surrounding the through groove 201 are forged. The through groove 201 is a material reduction groove that penetrates along the thickness direction of the blank 200 and is located at the inner hole processing area. Therefore, the material reduction groove does not affect the forming of the decorative cover body 100 and can save materials. The plurality of positioning holes 202 are used to position the blank 200 in the subsequent process to ensure the processing accuracy. When forging the blank 200, the thickness of the area 115a corresponding to the assembly hole 115 on the blank 200 is made greater than the thickness of the remaining areas, so that the strength of the assembly parts such as rivets and screw parts assembled here can be guaranteed. When one or more of the assembly holes 115 are internal screw holes, sufficient thickness can be left to process the internal threads.

[0058] In this embodiment, the forged blank 200 is a rough blank that matches the shape of the decorative cover body 100 to be formed. Forging the rough blank through the forging process can reduce the processing allowance of the subsequent process, reduce the processing time, and improve the processing efficiency. Specifically, when forging the rough blank, the blank 200 has a first forming area 210 for forming the first decorative area 110 and a second forming area 220 for forming the second decorative area 120. The shape of the first forming area 210 matches the shape of the first decorative area 110 for forming the first decorative area 110, and the shape of the second forming area 220 matches the shape of the second decorative area 120 for forming the second decorative area 120.

[0059] S120, blank 200 shape processing. Among them, please refer to Figure 3 , this step includes the following sub-steps:

[0060] S121, processing the outer edge of the first side surface 200a of the first molding area 210 and the first side surface 200a of the second molding area 220 to shape the appearance of the first surface 100a of the decorative cover body 100;

[0061] S122, processing the outer edge of the second side surface 200b of the first molding area 210 and the second side surface 200b of the second molding area 220 to shape the appearance of the second surface 100b of the decorative cover body 100, wherein the second surface 100b is a side surface opposite to the first surface 100a;

[0062] S123, the second end face of the second molding area 220 (corresponding to the second end face of the second decorative area 120), the first side edge (corresponding to the first side edge 122 of the second decorative area 120), the second side edge (corresponding to the second side edge 123 of the second decorative area 120) and the outer peripheral surface of the first molding area 210 are processed (CNC processing) to form the outer peripheral surface of the entire decorative cover body 100.

[0063] S124, grinding and rough polishing the areas processed in steps S121, S122 and / or S123.

[0064] S130 , processing the assembly groove 113 on the first side surface 200 a of the blank 200 along the thickness direction of the blank 200 .

[0065] The first side surface 200 a of the blank 200 is the same surface as the first surface 100 a of the decorative cover body 100 after processing and forming, and the second side surface 200 b of the blank 200 is the same surface as the second surface 100 b of the decorative cover body 100 after processing and forming.

[0066] See also Figure 4a and Figure 4b The assembly groove 113 is an annular groove, the outer ring wall of the annular groove is configured as a circular ring wall, and the inner ring wall of the annular groove is configured as a special-shaped ring wall adapted to the shape of the inner hole 114. The area enclosed by the assembly groove 113 forms an inner hole processing area 211 for forming the inner hole 114.

[0067] In this step, the assembly groove 113 is processed on the first side surface 200a of the first molding area 210 along the thickness direction of the blank 200. Figure 4 The assembly groove 113 is processed by the following sub-steps:

[0068] S131, taking the inner hole processing area 211 as a reference, a plurality of reference grooves 212 are processed on the outer periphery of the inner hole processing area 211, and the center of the area surrounded by the plurality of reference grooves 212 is concentric with the center of the inner hole processing area 211, which is used as a reference for the concentric processing of the assembly groove 113. In this way, the special-shaped annular wall of the assembly groove 113 after processing and forming can be consistent in shape and size with the outer wall of the inner hole 114, thereby improving the processing accuracy, reducing the defective rate, and improving the fit between the lens decorative cover and the lens after processing and forming.

[0069] S132, based on the plurality of reference grooves 212, the assembly groove 113 is processed so that the groove bottom surface of the assembly groove 113 is lower than the first side surface 200a of the blank 200, and the assembly groove 113 is concentrically surrounded by the outer periphery of the inner hole processing area 211.

[0070] S140, machining a plurality of assembly holes 115 around the outer circumference of the inner hole 114 in the assembly groove 113. The distribution position and quantity of the assembly holes 115 are determined according to the requirements of different implementation methods, and are therefore not limited here.

[0071] S150, processing the inner hole 114 based on the distribution area of ​​the lens assembly to obtain the decorative cover body 100. The inner hole 114 penetrates the blank 200 along the thickness direction of the blank 200 and is concentric with the assembly groove 113. The inner hole 114 is used to surround the outer periphery of the lens assembly. Figure 5 As one implementation method, this step includes the following sub-steps:

[0072] S151, see Figure 5a, the second side surface 200b on the blank 200 opposite to the first side surface 200a is used as a processing surface, and the inner hole processing area 211 is removed to form the inner hole 114, thereby obtaining the decorative cover body 100. In this embodiment, the outer peripheral edge 211a of the inner hole processing area 211 (the hole wall of the inner hole 114) is used as a reference, and the inner edge seam 211b located inside the outer peripheral edge 211a and having a matching shape is processed.

[0073] S152 , gradually processing from the inner edge seam 211 b outward to the outer peripheral edge 211 a , so that the inner hole processing area 211 is separated from the blank 200 .

[0074] By using the processing method in steps S151 and S152, the inner edge seam 211b is first opened, so that the processing tool gradually processes from the inside to the outside to the outer periphery 211a of the inner hole processing area 211. Compared with the traditional method of processing the inner hole 114 from the outer periphery 211a of the processing area, the processing accuracy can be ensured and poor processing of the hole wall of the inner hole 114 can be prevented.

[0075] S160 , fine polishing the outer shape of the decorative cover body 100 .

[0076] S170 , surface PVD treatment: performing PVD treatment on the surface of the decorative cover body 100 .

[0077] S180, riveting rivets. Based on the requirements of different implementations, rivets are riveted to the corresponding assembly holes 115. Based on the requirements of different implementations, internal threads may also be processed on the corresponding assembly holes 115.

[0078] S190, insert the decorative back plate into the assembly groove 113 to obtain a decorative lens cover.

[0079] The decorative back plate is provided with through holes for the lenses to pass through at positions corresponding to the respective lenses. The decorative back plate can be installed into the assembly groove 113 of the assembly groove 113 body during the process of assembling the lens decorative cover with the electronic device according to the requirements to be combined with the decorative cover body 100 to obtain the lens decorative cover. The decorative back plate can also be installed into the assembly groove 113 of the decorative cover body 100 in a subsequent process after the decorative cover body 100 is processed and formed.

[0080] Those skilled in the art can understand that the order of the steps described above is not unique. In different embodiments, the order of some steps can be adjusted according to different embodiments, for example, steps S120 to S150 can be adjusted according to the processing requirements of different embodiments. Those skilled in the art can also understand that some of the steps described above are not necessary steps and can be deleted or replaced according to the requirements of different embodiments, such as steps S160 to S180, such as step S124, etc.

[0081] Based on the above embodiments, the manufacturing method of the lens decorative cover and the lens decorative cover of the present invention have the following beneficial effects: the lens decorative cover is configured as a combined decorative cover body 100 and a decorative back plate, and different decorative back plates can be replaced according to the requirements of different embodiments, so as to provide a diversified lens decorative cover that is more suitable for the appearance of electronic equipment, and can also reduce the complexity of surface processing of the decorative cover body 100. When processing the decorative cover body 100, the decorative back plate can be installed into the bottom surface of the groove of the assembly groove 113 through the assembly groove 113 processed on the first side surface 200a of the blank 200. The material of the decorative back plate can be diversified and can be configured according to the requirements of different embodiments. Compared with the single material of the decorative cover body 100, it is more conducive to surface processing for the appearance of different electronic devices.

[0082] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
