Description
Technical Field
The application belongs to the technical field of communication, and particularly relates to a processing method of a shell, the shell and electronic equipment.
Background
With the extremely pursuit of users for use experience, the performance requirements and the appearance requirements of the users for mobile phones, tablet computers and other electronic devices are also higher and higher. The housing is a main structural member and an exterior member of the electronic device, and the performance and the appearance of the housing are widely paid attention to by users. Among them, leather-textured shells are increasingly popular with users because of their superior drop resistance and texture.
In the related art, in order to obtain a rich appearance effect, a leather-textured shell generally has a color separation effect, i.e., at least two different colors are formed on the surface of the shell. In the prior art, leather with different colors is usually spliced to achieve a color separation effect, or patterns are painted on the leather to achieve the color separation effect.
However, by adopting the scheme of leather splicing, the problem of poor adhesion between leather is easy to occur, so that the shell is cracked. The colored drawing is carried out on leather, so that the defects of unclear patterns, large chromatic aberration and easy generation of different color points are easily generated due to poor covering power of the colored drawing patterns, and the color separation effect is poor. That is, it is difficult to achieve both high intensity and good color separation effect with the existing case color separation schemes.

and spraying finishing paint on the first surface of the shell body to form a finishing paint layer so as to obtain the shell.
In a second aspect, the present application also discloses a housing, which is made by the processing method described in any one of the above.
In a third aspect, the application further discloses an electronic device, which is characterized in that the electronic device comprises the housing.
In this embodiment of the present application, by silk-screen printing an ink layer in a first area of a first surface of a housing body, a color of the ink layer is different from a color of the housing body, and the ink layer may give the housing color separation graphic-text effect.

Referring to fig. 1, a step flowchart of a method for processing a shell according to an embodiment of the present application is shown, and as shown in fig. 1, the method for processing a shell may specifically include the following steps:
step 101: and silk-screen printing the ink layer in a first area of the first surface of the shell body, wherein the shell body is leather, and the color of the ink layer is different from that of the shell body.
In the present embodiment, the housing body 10 may be leather in texture. The housing body 10 may be cut from a whole roll of leather. As shown in fig. 2, the housing body 10 may include a first surface 101 and a second surface 102 disposed opposite and facing away from each other, wherein the first surface 101 may serve as an exterior surface of the housing body 10 and the second surface 102 may serve as a lining surface.
Specifically, as shown in fig. 3, a silk-screen process may be used to form the silk-screen ink layer 11 on the first region of the first surface 101 of the housing body 10, where the color of the ink layer 11 is different from the color of the housing body 10, so that the first surface 101 of the housing body 10 exhibits at least two different colors, one being the color of the housing body 10 itself and the other being the color of the ink layer 11. The ink layer 11 can give the shell a color separation graphic effect
In practical application, since the silk screen printing can design the content of the ink layer 11 by setting the pattern of the screen, the ink layer 11 can show rich content, and the appearance richness of the ink layer 11 is improved. For example, the ink layer 11 may be text, graphics, or a combination of text and graphics, and the pattern of the ink layer 11 is not particularly limited in the embodiments of the present application.
Moreover, the ink layer 11 formed by silk screen printing has better connection strength with the shell body 10, and the appearance of the ink layer 11 has the advantages of clear pattern and small chromatic aberration, so the color separation effect of the shell can be further improved,
In practical applications, the colors of the case body 10 and the ink layer 11 may be set according to practical situations. For example, the color of the case body 10 may be orange, the color of the ink layer 11 may be brown or the like, which is different from orange. The color of the case body 10 and the ink layer 11 is not particularly limited in the embodiment of the present application.
Step 102: and carrying out imprinting treatment on the first area so as to form a stereoscopic texture in the first area.
In this embodiment, after the ink layer 11 is formed on the first area of the first surface 101 of the housing body 10, the ink layer 11 on the first area may be subjected to an embossing process by using a leather embossing process, so that the three-dimensional texture 12 is formed at the position of the ink layer 11 of the housing body 10. By forming the texture 12 on the ink layer 11, the shell body can be endowed with three-dimensional texture and leather texture, and the color separation effect of the rear cover is further improved.
As shown in fig. 4, the three-dimensional texture 12 may be realized by alternately disposing the concave portions 121 and the convex portions 122. The recess 121 may be recessed below the first surface 101 and the protrusion 122 may be raised above the first surface 101. By alternately disposing the concave portions 121 and the convex portions 122, the ink layer 11 and the case body 10 under the ink layer 11 can be formed together into a three-dimensional texture 12. Thus, at the position of the ink layer 11, not only the effect of fig. Wen Fense can be represented, but also the three-dimensional cortical texture 12 can be represented, so that the color separation effect of the shell is further enriched, and the appearance richness of the shell is improved.
Step 103: and spraying finishing paint on the first surface of the shell body to form a finishing paint layer so as to obtain the shell.
In this embodiment, after the first surface 101 of the housing body 10 is textured 12, the first surface 101 of the housing body 10 may be sprayed with a topcoat to form the topcoat layer 13 shown in fig. 5. Specifically, the topcoat layer 13 may serve to protect the case body 10, as well as the ink layer 11 and the texture 12, to protect the color separation effect of the case, and to improve the durability of the case.
Alternatively, the topcoat layer 13 may be a transparent topcoat layer to avoid masking of the ink layer 11 and texture 12 by the topcoat layer 13, protecting the color separation effect of the housing.
In practical application, the shell obtained by adopting the processing method not only has color separation image-text effect, three-dimensional texture and leather texture, and realizes exquisite appearance effect, but also has higher strength due to avoiding adopting the leather splicing technology, and the durability of the shell can be further improved due to the arrangement of the finish paint layer 13.
In summary, the method for processing a housing according to the embodiments of the present application may at least include the following advantages:
in this embodiment of the application, through the first region silk screen printing ink layer at the first surface of casing body, the colour of ink layer with the colour of casing body is different, the ink layer can give the casing colour separation picture and text effect. The first area is subjected to embossing treatment to form a three-dimensional texture on the ink layer of the first area, so that the shell can be endowed with three-dimensional texture and leather texture; the first surface of the shell body is sprayed with a finishing paint layer to form a finishing paint layer, the finishing paint layer can protect the ink layer and the textures, the color separation effect of the shell is protected, and the durability of the shell is improved. That is, the shell obtained by the processing method not only has color separation graphic effect, three-dimensional texture and leather texture, and realizes exquisite appearance effect, but also has higher strength due to avoiding the adoption of leather splicing technology, and the durability of the shell can be further improved due to the arrangement of the finish paint layer.
Referring to fig. 6, a step flow chart of another method for processing a shell according to an embodiment of the present application is shown, and as shown in fig. 6, the method for processing a shell may specifically include the following steps:
step 601: and cleaning the first surface of the shell body by adopting a plasma cleaning machine.
In this embodiment of the application, the first surface 101 of the housing body 10 may be pretreated by using the plasma cleaning machine, so as to achieve the purpose of cleaning the first surface 101 of the housing body 10, improve the adhesion performance of the housing body 10, and facilitate the adhesion of the ink on the first surface 101 in the subsequent silk-screen process.
Specifically, the plasma cleaning machine can generate disordered plasmas with high energy by starting a radio frequency power supply under a certain pressure condition, and can achieve the purpose of cleaning the first surface 101 by bombarding the first surface 101 of the shell body 10 with the plasmas, so that the adhesion performance of the leather surface is improved.
In practical applications, without cleaning the first surface 101 of the case body 10, there is a possibility that the ink molecules cannot be well bonded to the case body 10 in the subsequent screen printing process, so that the ink layer 11 easily drops off in normal wear or the ink layer 11 cracks when flexed. Therefore, by increasing the cleaning process for the case body 10 in the screen printing, the adhesion reliability of the ink layer 11 to the case body 10 can be improved, and thus, the phenomenon that the ink layer 11 falls off or cracks can be avoided.
Step 602: the silk screen printing ink layer is printed on a first area of a first part of the shell body, the silk screen printing ink layer is printed on a second part of the shell body, the first part and the second part are arranged in a staggered mode, the second part at least comprises a top area and a bottom area of the shell body, and the top area and the bottom area are both provided with the positioning parts.
In the embodiment of the present application, the housing body 10 may be divided into a first portion 103 and a second portion 104. The first portion 103 may be the portion of the housing that ultimately needs to be retained, and the second portion 104 may be the portion that needs to be cut away during processing of the housing.
As shown in fig. 8, the ink layer 11 may be screen printed in a partial region of the first portion 103 of the housing body 10 so that the ink layer 11 may remain on the final housing to achieve a color separation effect. Meanwhile, the positioning portion 111 may be silk-screened on the second portion 104 of the housing body 10, and the positioning portion 111 may be used for positioning in subsequent imprinting to improve imprinting accuracy. Because the first portion 103 and the second portion 104 are arranged in a staggered manner, the positioning portion 111 can be arranged to avoid the ink layer 11, so that the imprinting operation on the ink layer 11 by referring to the positioning portion 111 in the subsequent imprinting process is facilitated.
Alternatively, the second portion 104 may include at least a top region and a bottom region of the housing body 10, both of which may be silk-screened with the positioning portion 111. In practical application, the positioning portions 111 are respectively screen-printed from the top region and the bottom region of the housing body 10, so that the positioning portions 111 on the top region and the bottom region are respectively referred to for positioning in the stamping process, and the positioning accuracy of the positioning portions 111 is further improved.
As shown in fig. 8, the top region may be provided with a plurality of positioning portions 111, the bottom region may be provided with a plurality of positioning portions 111, and the positioning portions 111 of the top region and the positioning portions 111 of the bottom region are aligned so as to facilitate positioning with reference to the positioning portions 111 in a subsequent imprinting process.
Optionally, the step of silk-screen printing the ink layer on the first area of the first surface of the housing body may specifically include the following substeps:
substep S11: and covering the first surface of the shell body with a screen plate, wherein the screen plate is provided with patterns, meshes are arranged at the positions of the patterns, and the patterns are opposite to the partial areas.
In this embodiment, the screen may be covered on the first surface 101 of the housing body 10, and the pattern is opposite to the first area where the first surface 101 needs to form the ink layer 11, so that the screen is used to perform screen printing on the first area of the first surface 101 to obtain the ink layer 11. The screen is provided with a pattern, which may be provided with openings, through which openings the ink may be transferred to the first area of the first surface 101 to obtain the ink layer 11.
Specifically, nylon, polyester fiber or stainless steel wire mesh can be stretched on a screen frame to be tensioned and fixed, and the screen is manufactured according to graphic design by adopting a photochemical plate making method. The mesh number of the screen printing plate can be set according to practical situations, and can be generally set to 250-300 meshes.
In particular applications, the mesh number of the screen is required to sufficiently consider the composition and parameters of the ink, and the thicknesses and colors of the ink layers 11 made of the screens with different mesh numbers are different.
In the embodiment of the present application, since the subsequent imprinting process needs to be performed on the ink layer 11, the ink for silk screen printing needs to have the characteristics of high temperature and high pressure resistance, no color change, and no mold sticking. Specifically, the ink can be prepared from high-temperature-resistant ink raw materials, a hardening agent, an additive and a diluent, so that the ink has the characteristics of high temperature resistance, high pressure resistance, no color change and no die sticking.
Specifically, the high-temperature-resistant ink raw material, the hardener, the additive and the diluent can be placed into a high-speed mixer, and the mixture is uniformly dispersed at a high speed in the high-speed mixer to prepare the required silk-screen printing ink. The ratio of the hardening agent is 100:5-100:500, and the ratio of the additive is 100:1-100:10.
For example, the ink raw material may include a resin such as a polyester resin, an acrylate resin, and a pigment such as titanium pigment, carbon black, and the like. The hardener may include polyisocyanates and the like. The additives may include defoamers, leveling agents, dispersants, thixotropic agents, matting agents, and the like. The diluent may include ketones (methyl ethyl ketone, cyclohexanone, isophorone, etc.), esters (ethyl acetate, butyl acetate, etc.), dibasic acid esters, etc.
Substep S12: ink is placed on the screen and scraped using a squeegee at an oblique angle of 60 degrees to 65 degrees to transfer the ink from the mesh to the first surface of the housing body to form an initial ink layer.
In this embodiment of the present application, the formulated ink may be poured into one end of the screen. The ink will not normally leak onto the housing body 10 by itself through the openings in the screen without the action of external forces. In a specific application, a rubber blade may be used to scrape the ink at an angle of inclination of 60 ° -65 ° and pressure to transfer the ink through the openings of the screen pattern onto the housing body 10 under the screen, forming an initial ink layer of 5-20 μm, thereby achieving the multicolor effect of the first surface 101 of the housing body 10.
In the silk screen printing process, the pressure and angle of the scraping plate need to be focused. When the pressure is small and the squeegee angle is large, the transfer amount of ink is also small, which easily causes defects of a thinner ink layer 11 and weak covering force. The squeegee may not contact the first surface 101 of the housing body 10 when the pressure is too low to perform the screen printing. The greater the pressure and the smaller the squeegee angle, the greater the transfer amount of ink, which easily results in an excessively thick ink layer 11. And too much pressure can cause bending deformation of the scraping plate, which affects printing quality.
Substep S13: and baking the shell body to solidify the initial ink layer to obtain the ink layer.
In this embodiment of the present application, the housing body 10 after silk screen printing may be placed in a baking oven, and the initial ink layer is baked and dried for 30 minutes to 2 hours under a temperature condition of 50-90 degrees, so that the initial ink layer sufficiently performs a curing reaction, so as to obtain the ink layer 11, and the adhesion between the ink layer 11 and the first surface 101 of the housing body 10 is stronger.
Step 603: and referring to the positioning part, carrying out imprinting treatment on the first area so as to obtain a three-dimensional texture.
In this embodiment, since the positioning portion 111 has been obtained by screen printing in step 602, in the process of performing the imprinting process on the ink layer 11, the imprinting process may be performed on the ink layer 11 with reference to the positioning portion 111, to obtain the three-dimensional texture 12 shown in fig. 9. Since imprinting can be performed with reference to the positioning portion 111, the imprinting position can be adapted to the silk-screen position to improve accuracy of the imprinting position, and thus, position accuracy of the three-dimensional texture 12 formed on the ink layer 11 can be improved.
Optionally, referring to the positioning portion, the step of performing the imprinting process on the ink layer may include:
substep S11: and processing the positioning part into a positioning through hole by adopting a laser cutting process.
In this embodiment of the present application, a laser cutting process may be first adopted to process the positioning portion 111 into a positioning through hole, so that a corresponding positioning post is inserted into the positioning through hole in a subsequent imprinting process, so as to implement imprinting positioning.
Substep S12: and carrying out imprinting treatment on the ink layer by referring to the positioning through holes so as to adapt an imprinting position to the silk-screen position.
In this embodiment of the present application, the positioning through hole may be used to place the housing body 10 after silk-screen printing on the stamping base of the high-frequency stamping machine. Loading the texture mold to the high frequency embossing machine, heating the texture mold, setting high frequency current, and applying pressure according to the depth of the required texture 12 to form clear and shaped three-dimensional texture 12 on the ink layer 11 of the shell body 10.
Specifically, the high-frequency high-current of the high-frequency stamping machine flows to a heating coil (usually made of copper tubes) wound into a ring shape or other shapes. Thereby generating strong magnetic flux with instant polarity change in the coil, and penetrating the magnetic flux to the first surface 101 of the housing body 10 through the texture mold. In the opposite direction of the housing body 10 to the heating current, a corresponding large eddy current is generated. Since the resistor exists in the case body 10, a lot of joule heat is generated, and the temperature of the case body 10 itself is rapidly increased. Thereby achieving the purpose of branding the textures 12 on the first surface 101 of the shell body 10.
Alternatively, the imprinting temperature may be 50 degrees to 100 degrees and the imprinting time may be 4 seconds to 20 seconds during the imprinting process of the ink layer 11, so as to form the clear and shaped three-dimensional texture 12 on the ink layer 11 of the housing body 10.
Step 604: and removing the second part of the shell body by adopting a laser cutting process.
In this embodiment, as shown in fig. 10, the second portion 104 of the housing body 10 may be removed using a laser cutting process to form the final contour of the housing. In practical applications, the step of forming the outline by laser cutting is arranged after the step of silk-screen printing and embossing, so that the influence on the outline of the shell body 10 in the silk-screen printing and/or embossing process can be avoided, and the dimensional accuracy of the finally obtained shell can be improved.
Step 605: and spraying finishing paint on the first surface of the shell body to form a finishing paint layer so as to obtain the shell.
In this embodiment, after the first surface 101 of the housing body 10 forms the texture 12, the surface of the housing body 10 may be sprayed with a finish to form the finish layer 13. Specifically, the topcoat layer 13 may serve to protect the case body 10, as well as the ink layer 11 and the texture 12, to protect the color separation effect of the case, and to improve the durability of the case.
Specifically, the finish paint can be formulated before the finish paint is sprayed. The preparation process of the finishing paint specifically comprises the following steps: the resin composition is prepared by blending a certain proportion of a high gloss resin, a matte resin (polyester resin, acrylic resin, etc.), a curing agent (polyisocyanate, etc.), a solvent (alcohols (ethanol, isopropanol, etc.), ketones (methyl ethyl ketone, cyclohexanone, isophorone, etc.), esters (ethyl acetate, butyl acetate, etc.), dibasic acid esters, etc.), and a proper amount of an auxiliary agent (defoamer, leveling agent).
In practical application, adding a top-coat paint on the first surface 101 of the housing body 10 can protect the housing body 10 and the ink layer 11, and meanwhile, the gloss, texture clarity and feel of the housing can be improved. The glossiness of the shell can be adjusted through different proportions of high-gloss resin and matte resin, and also can be adjusted through adding silica matte powder; the texture clarity of the shell can be adjusted by different topcoat thicknesses; the hand feeling of the shell can be adjusted by selecting resins with different hardness and adding a proper amount of hand feeling auxiliary agent, and the shell is smooth to dry.
Specifically, after the finish paint is formulated, the finish paint can be sprayed. The spraying process of the finish paint specifically comprises the following steps: the shell body 10 is clamped through a customized jig, and after the surface of the shell body 10 is confirmed to be flat, spraying is performed in a spraying production line. Between spraying the top coat, the housing body 10 may be pre-baked. During spraying, the film thickness of the finishing paint can be controlled by a film thickness sheet, and finally, a layer of finishing paint is uniformly adhered to the first surface 101 of the shell body 10, so that a finishing paint layer 13 is obtained, and the shell body 10 and the ink layer 11 are protected.
In practical application, after the step of spraying the finish paint, the finish paint baking operation can be performed. The baking process of the finish paint specifically comprises the following steps: and baking at low temperature by a spraying production line, and baking by an off-line baking oven to fully solidify the finish paint layer 13. The finish paint layer 13 on the first surface 101 of the shell body 10 forms an ideal and desirable finish paint layer 13 with proper protection and glossiness through the curing processes of melting, leveling, adhesive film forming and the like under the action of the temperature in the drying tunnel and the oven.
