Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort shall fall within the protection scope of the present application. It should be noted that the embodiments and/or features of the embodiments of the present application may be combined with each other without conflict.

The embodiment of the application provides a processing method of a shell, which is used for processing the shell of electronic equipment. The electronic device includes, but is not limited to, electronic products such as a mobile phone, a tablet computer, an electronic reader, a remote controller, a notebook computer, a vehicle-mounted device, a network television, and a wearable device. Preferably, the electronic device is a mobile phone. The shell can be a single-piece shell of the electronic equipment, and can also be a shell component formed by assembling at least two single-piece shells.

In one embodiment, the housing to be processed by the processing method is referred to as a first housing to distinguish a second housing to be described below. The processing method can comprise the following steps:

s11: providing a first shell, wherein the first shell is provided with a first surface, and the first surface is provided with a first boundary and a second boundary which are opposite;

s12: coating a magnetic paint containing magnetic pigment particles on the first surface;

s13: providing a magnetic jig;

s14: the magnetic jig is matched with the first shell coated with the magnetic paint, so that the magnetic jig is opposite to the first surface, one end of the magnetic jig is positioned between the first boundary and the second boundary, and the other opposite end of the magnetic jig is aligned with or extends out of the second boundary, so that the magnetic pigment particles in the magnetic paint gradually move from the first boundary to the second boundary under the magnetic force action of the magnetic jig.

The various steps of the method are described in detail below with reference to specific figures.

As shown in fig. 1 and 2, the first housing 10 provided in step S11 is not limited to be manufactured by plastic molding process (e.g., injection molding process), metal processing process (e.g., die casting, stamping, numerical control processing). The first surface 101 of the first housing 10 will be material coated to form a surface texture. The first surface 101 is preferably a design surface, but may be a non-design surface. The shape of the first surface 101 is based on the actual design requirement, and the first boundary 101a and the second boundary 101b are two opposite sides of the first surface 101. For example, when it is required to form a belt-shaped surface texture region, the first boundary 101a and the second boundary 101b define the belt-shaped first surface 101.

As shown in fig. 2 (fig. 2 is a partial side view of the first housing 10 in fig. 1 projected in the direction of the straight arrow), the step S12 "coating" refers to covering the first surface 101 with magnetic paint, including but not limited to spraying. When the spraying mode is adopted, the spraying can be carried out by a manual spray gun or an automatic spray gun. The magnetic paint is used for forming a texture effect on the first surface 101, and the components of the magnetic paint can comprise magnetic pigment, binder, filler and auxiliary agent. Preferably, the magnetic coating may be a magnetic ink. The magnetic pigment is composed of magnetic pigment particles, which are capable of being dyed and have magnetic properties. Magnetic pigment particles include, but are not limited to, black iron oxide (Fe)₃O₄) And brown iron oxide (Fe)₂O₃) Usually, it is a needle crystal having a particle diameter of less than 1 μm. The content of the magnetic pigment can be determined according to the specific design requirements, for example, 2% -10%. The binder determines the rheological property, viscosity, drying property, film forming property and spraying property of the magnetic coating. Filler as filler of magnetic paint for reducing magnetic paintThe amount of the magnetic pigment in the paint is reduced, the material cost is reduced, the color of the magnetic paint is adjusted, and the spraying performance of the magnetic paint is improved. The auxiliary agent is an additional material in the magnetic coating and is used for improving the performance of the magnetic coating, such as oxidation resistance, friction resistance and the like. The thicker the coating thickness of the magnetic paint is, the more the magnetic pigment particles are, the stronger the magnetism is. Of course, the thickness and width of the coating (width refers to the distance from the first boundary 101a to the second boundary 101 b) are subject to practical requirements, for example, the thickness is 8 μm to 12 μm, and the width is 0.5 mm. In the present embodiment, the magnetic paint covers the entire first surface 101 from the first boundary 101a to the second boundary 101 b. In addition, in the present embodiment, a primer may be sprayed on the first housing 10 in advance before the magnetic paint is applied, so that the first surface 101 is covered with the primer, and the magnetic paint is applied on the primer layer.

The magnetic fixture provided in step S13 is used to provide magnetic force to drive the magnetic pigment particles to displace. The magnetic fixture is adapted to the structure of the first housing 10, for example, can be contoured (i.e., have similar shape and configuration, and matching dimensions) to the first housing 10 to achieve precise matching with the first housing 10, thereby precisely driving the magnetic pigment particles to generate the desired displacement. It should be understood that the sequence of step S13 and step S11 is not limited.

As shown in fig. 3, in step S14, the coated first housing 10 is matched with the magnetic fixture 20, such as the first housing 10 is mounted on the magnetic fixture 20, or the magnetic fixture 20 is mounted on the first housing 10. The specific requirements of the matching are as follows: the magnetic jig 20 is made to face the first surface 101 of the first housing 10, one end of the magnetic jig 20 is located between the first boundary 101a and the second boundary 101b, and the other opposite end is aligned with the second boundary 101b or extends out of the second boundary 101b (i.e. when the other end of the magnetic jig 20 is aligned with the second boundary 101b, the size of the magnetic jig 20 is smaller than the size of the first surface 101 in the direction from the first boundary 101a to the second boundary 101b, and the magnetic jig 20 is placed close to the second boundary 101b of the first surface 101, and when the other end of the magnetic jig 20 extends out of the second boundary 101b, the relationship between the size of the magnetic jig 20 and the size of the first surface 101 is not limited in the direction from the first boundary 101a to the second boundary 101b, but the magnetic jig 20 is arranged to be offset from the first surface 101). Due to the relative position relationship between the magnetic jig 20 and the first surface 101, the magnetic force applied to the magnetic pigment particles on the first surface 101 is substantially directed from the first boundary 101a to the second boundary 101b, so that the magnetic pigment particles gradually move from the first boundary 101a to the second boundary 101b, and the magnetic pigment particles are less retained in the region closer to the first boundary 101a and more accumulated in the region closer to the second boundary 101 b. After a preset time period, a color gradient effect from the first boundary 101a to the second boundary 101b is formed. The magnetic paint near the first boundary 101a is fused with the primer, so that the color of the side is naturally transited without color mutation. In this embodiment, the distance between the magnetic fixture 20 and the first surface 101 affects the magnitude of the applied magnetic force, and further affects the displacement of the magnetic pigment particles and the final color gradient effect. Therefore, the distance between the magnetic fixture 20 and the first surface 101 can be adjusted according to actual needs.

In the processing method of the embodiment, by designing the magnetic jig 20 adapted to the structure of the first housing 10, the first surface 101 of the first housing 10 is coated with the magnetic paint, and the magnetic jig 20 and the first housing 10 are clamped together, so that the magnetic jig 20 corresponds to a partial region of the first surface 101, and the magnetic force of the magnetic jig is utilized to attract the magnetic pigment particles on the first surface 101 from the region corresponding to the magnetic jig 20 to the region corresponding to the magnetic jig 20, so that the magnetic pigment particles on the first surface 101 gradually accumulate toward the second boundary 101b, and finally, a color gradient effect from the first boundary 101a to the second boundary 101b from light to dark is presented. Therefore, the processing method can manufacture the shell with gradually changed textures (including appearance surface textures and/or non-appearance surface textures), breaks through the limitation that the conventional shell only has monotonous solidified surface textures, improves the differentiated experience of electronic equipment, and enhances the product competitiveness.

Further, as shown in fig. 1, the first casing 10 provided in step S11 may include a body 11 and a rim 12. The frame 12 is connected to the body 11 by bending, and the bending angle is based on actual needs, and may be 90 degrees, for example. The bending part can be designed into a round angle. The frame 12 surrounds the periphery of the body 11 to form a receiving cavity a, and the receiving cavity a can be used for receiving other components of the electronic device. Accordingly, as shown in fig. 1 and 2, the first surface 101 is an outer side surface of the frame 12 (i.e., an external surface connected to the body 11 and surrounding the body 11), and the outer side surface may be all or part of the outer side surface of the frame 12. The second boundary 101b is located at the opening of the containing cavity a, that is, the second boundary 101b is a side line of the outer side surface far away from the body 11.

Accordingly, step S14 may include:

s141: the magnetic jig 20 is arranged in the accommodating cavity A, so that the frame 12 surrounds the periphery of the magnetic jig 20; alternatively, the first and second electrodes may be,

s142: the magnetic fixture 20 is disposed outside the receiving cavity a and close to the frame 12.

Specifically, as shown in fig. 5, in step S141, the first casing 10 is sleeved outside the magnetic fixture 20, and the first surface 101 and the magnetic fixture 20 are not directly opposite to each other, but are separated by the thickness of the frame 12. At this time, the magnetic jig 20 may have a complete appearance and structure (for example, a complete plate or block shape), which is convenient for manufacturing the magnetic jig 20 and is also beneficial for reliable clamping; and the magnetic jig 20 does not touch the magnetic paint on the first surface 101, thereby avoiding processing abnormality. Alternatively, the magnetic fixture 20 may be clamped outside the first casing 10 in the manner of step S142, and the first surface 101 is directly opposite to the magnetic fixture 20. At this time, in order to match the shape of the frame 12, the magnetic fixture 20 may surround the whole frame 12 in an overall ring shape, or may be divided into several separate sections, where each section corresponds to one section of the frame 12. The step S142 can provide stronger magnetic force, and can cause larger displacement of the magnetic pigment particles, thereby generating more obvious color gradient effect. Of course, the present embodiment is not limited thereto.

Further, as shown in fig. 5 and fig. 6, the frame 12 provided in step S11 may further have a mating surface 102 adjacent to the first surface 101, and a boundary between the mating surface 102 and the first surface 101 is the second boundary 101 b. The mating surface 102 is used for mating with the magnetic fixture 20.

Accordingly, as shown in fig. 5, the magnetic fixture 20 provided in step S13 may include a substrate 21 and a magnet 22, wherein the substrate 21 is connected to the magnet 22, and the contour of the magnet 22 is recessed within the contour of the substrate 21 (i.e. the projection of the magnet 22 in the direction perpendicular to the surface of the substrate 21 falls entirely within the surface of the substrate 21). The substrate 21 may be made of a non-magnetic material, such as a monolithic non-magnetic sheet. The magnet 22 includes, but is not limited to, permanent magnet material made of permanent magnet material, such as metal permanent magnet material, ferrite permanent magnet material, rare earth permanent magnet material, and the like, specifically alnico permanent magnet, sintered ferrite permanent magnet, neodymium iron boron permanent magnet, and the like.

Correspondingly, as shown in fig. 5 and fig. 6, step 141 may specifically be: the magnetic fixture 20 is placed in the receiving cavity a, so that the frame 12 surrounds the periphery of the magnet 22, and the substrate 21 is fastened on the mating end surface 102. The base 21 is designed to facilitate the clamping of the magnetic fixture 20 with the first housing 10, so that the magnet 22 is accurately positioned to the corresponding position of the first housing 10 to apply the magnetic force according to the design expectation. Therefore, for the first housing 10 having the frame 12, the processing method of the present embodiment forms a gradual texture on the first housing 10 according to the design expectation by designing the magnetic fixture 20 corresponding to the structure of the first housing 10.

Preferably, the magnetic fixture 20 can be made in the following manner. That is, further, step S13 may include:

s131: providing a substrate 21 and a magnet 22, wherein the substrate 21 has a processing surface;

s132: forming an accommodating groove on the processing surface, and enabling an opening edge of the accommodating groove to be retracted into the boundary of the processing surface;

s133: the magnet 22 is placed in the housing groove so that the magnet 22 partially protrudes from the processing surface.

Wherein the size of the receiving slot is based on the magnet 22. The edge of the opening of the housing groove, i.e., the edge of the opening of the housing groove on the processing surface, is located on the processing surface such that when the magnet 22 is mounted in the housing groove, the contour of the magnet 22 is retracted into the contour of the base 21. The portion of the magnet 22 exposed outside the pocket is used to provide a magnetic force. The magnetic jig 20 having a good positioning function and capable of stably providing magnetic force can be manufactured according to the embodiment. The manufacturing method has the advantages of simple process, convenient realization of batch and low cost. Of course, the magnetic fixture 20 can be manufactured in other manners.

Further, after step S133, step S13 may further include:

s134: the magnet 22 and the base material 21 are coated integrally with a coating material.

The coating material may have good structural strength, adhesion, flexibility, etc. to coat and connect the magnet 22 and the substrate 21. The cladding material does not shield the magnetic field and does not weaken the magnetic field strength of the magnet 22. The coating material may completely cover the magnet 22 and the base material 21, or may coat only the connecting portion between the magnet 22 and the base material. The integral magnetic jig 20 can be manufactured by coating the coating material, so that the magnetic jig 20 can be conveniently transported and clamped; it is also convenient to protect the magnet 22 and the substrate 21 for continuous use. Of course, the base 21 and the magnet 22 may be connected by other means, such as adhesion, interference fit, or engagement.

Further, after step S14, the processing method may further include:

s15: the magnetic paint applied on the first housing 10 is cured.

Specifically, the magnetic paint layer with a color gradient on the first shell 10 is cured, and the displacement of the final magnetic pigment particles and the formed color gradient are fixed, so that a texture gradient from the first boundary 101a to the second boundary 101b is obtained, and the texture gradient shows a gradient effect from light to dark from the first boundary 101a to the second boundary 101 b. For example, with the magnetic pigment particles that can dye the first surface 101 black, a natural gradation effect from white to black is exhibited from the first boundary 101a to the second boundary 101b after step S15. The "curing" process includes, but is not limited to, baking and curing, that is, the first housing 10 is placed in an oven to be cured for 8min to 10min, and the baking temperature is adjusted according to actual needs. Other means of curing, such as uv curing, may also be used depending on the nature of the magnetic coating used. Of course, step S15 is not required, and the color gradient effect can be fixed without forced curing, for example, by adjusting the components in the magnetic paint.

As shown in fig. 7, further, the processing method may further include:

s16, providing a second shell 30, wherein the second shell 30 is provided with a second surface 301;

and S17, assembling the second shell 30 and the solidified first shell 10 in a stacking mode, splicing the second surface 301 with the first surface 101 and enabling the second surface 301 to be adjacent to the second boundary 101b, wherein the color of the solidified second boundary 101b is the same as that of the second surface 301.

Specifically, the sequence of step S16 and steps S11-S15 is not limited. The second housing 30 provided in step S16 is not limited to be manufactured by plastic molding process (e.g., injection molding process), metal processing process (e.g., die casting, punch forming, and numerical control processing). The second surface 301 of the second housing 30 is given a specific color through a surface processing process. The second surface 301 corresponds to the position of the first surface 101, and is preferably a design surface, but may be a non-design surface. The shape of the second surface 301 is subject to the actual design requirements. Step S17 is performed after step S15. After the first housing 10 and the second housing 30 are assembled together in a stacked manner (for the embodiment where the first housing 10 includes the body 11 and the frame 12, the second housing 30 specifically covers the opening of the receiving cavity a of the first housing 10), the first surface 101 will be spliced with the second surface 301. The splicing means that two adjacent edges (the second boundary 101b of the first surface 101 and the edge adjacent to the second boundary 101b on the second surface 301) have no step difference, so that the two edges form a smooth or non-smooth butt joint, and the two edges visually form a surface. The first surface 101 and the second surface 301 can be spliced seamlessly, and a design gap can be reserved. In actual production, the color of the cured second boundary 101b and the color of the second surface 301 can be substantially the same by adjusting a suitable magnetic paint, designing a corresponding magnetic jig 20, and determining the assembly size of the magnetic jig 20 and the first housing 10. The light areas of the first surface 101 are more visually ignored and appear to be reduced in width than the dark areas at the second boundary 101b of the first surface 101 and on the second surface 301, so the width of the dark areas of the housing is determined primarily by the second surface 301 and the portion of the first surface 101 at the second boundary 101 b. Thus, the thickness of the shell visually assembled by the first shell 10 and the second shell 30 is mainly determined by the second shell 30 and the part of the first shell 10 at the second boundary 101b, and is not equal to the overlapping thickness of the second shell 30 and the first shell 10, so that the shell is thinner.

The embodiment also provides a shell which can be manufactured by adopting the processing method. For example, the housing may be a first housing 10 having a color gradient. As shown in fig. 8, the housing 40 may also include the first housing 10 and the second housing 30. The casing of this embodiment has gradual change texture, has promoted electronic equipment's differentiation and has experienced, has strengthened product competitiveness.

As shown in fig. 9 and 10, the present embodiment also provides an electronic apparatus 60 including the housing. Preferably, the electronic device 60 is a mobile phone.

Preferably, the housing 40 includes a first housing 10 and a second housing 30 that are in stacked fit, a side of the second housing 30 facing away from the first housing 10 is provided with a mounting groove B, and the second surface 301 is an outer surface of a side wall of the mounting groove B. The electronic device 60 may further include a display screen 50, the display screen 50 being mounted in the mounting groove B and conforming to the bottom wall of the mounting groove B. The electronic device 60 of the present embodiment has a visual thickness mainly determined by the second casing 30 and the portion of the first casing 10 at the second boundary 101b, and thus the overall device is thinner.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the present application, and these modifications or substitutions should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
