Detailed description of the invention
For making the object, technical solutions and advantages of the present invention of greater clarity, below in conjunction with detailed description of the invention and referring to the drawings, the present invention is described in more detail.It should be understood that these describe the most exemplary, and it is not intended to limit the scope of the present invention.Additionally, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring idea of the invention.
It should be noted that chamfer surface is the contact surface of phone housing (material of phone housing is metal) and screen, for the ease of expressing and stating conveniently, chamfer surface is referred to as surface to be colored.
Fig. 1 is the schematic flow sheet of the method repeatedly coloured by oxidation of the present invention.
Step S1, uses masking material to cover the Part I on the surface to be colored of metalwork.In this step, see Fig. 2, Fig. 2 is the initial effect figure on the surface to be colored after the CNC processing of the present invention, under normal circumstances, first the contact surface (surface the most to be colored) of metalwork (such as phone housing) Yu screen contact is carried out the processing of CNC height light, surface to be colored 30 (i.e. metal and the contact surface of screen) after the processing of CNC height light is typically the color of aluminium itself, in order to reach the technique effect of Rimless, need further described surface to be colored to be carried out subsequent treatment.The present invention, after CNC height light is processed, masking material is used to cover the Part I 10 on the surface to be colored 30 of metalwork, as shown in Figure 2, tool is such as used to be covered by the described Part I 10 on surface to be colored, it is therefore an objective to sprayed on material sprays to when preventing spray treatment this part.Here, metalwork is Al-alloy metal part, and described metalwork is the shell of portable terminal.In the present invention, masking material includes but not limited to cover tool, in an optional embodiment, it is possible to use described surface to be colored is covered by acid and alkali-resistance masking material or masking tape.
Step S2, sprays on the Part II on surface to be colored by coating material, and described Part II is the part in addition to described Part I on described surface to be colored.In this step, after Part I 10 on surface 30 to be colored is covered with masking material, use coating material to treat the Part II 20 in colored surface 30 to carry out spraying protective treatment, such as, can make to paint the Part II treated in colored surface 30 to carry out spraying protective treatment, it is therefore an objective to when preventing anodized, this Part II is oxidized anodically.
In the present invention, sprayed on material includes but not limited to paint.
Step S3, removes described masking material, and described Part I is carried out the first oxidation processes.
Step S4, colours the described Part I after oxidation.
In this step, after masking material on Part I 10 is removed, described Part I 10 carries out for the first time anodized, and after anodized, anode layer herein manifests, as shown in Figure 3, for the first time after anodized, again described a part of 10 in Fig. 3 are coloured so that it is in black, and screen itself is also black, in such manner, it is possible to realize real Rimless.After having coloured, continue to make the subsequent treatment such as sealing of hole to described Part I 10.
Further, described method also includes: step S5, removes the described coating material on described Part II, described Part II is carried out the second oxidation processes.
In this step, after coating material on Part II 20 on surface 30 to be colored is removed, Part II on described surface 30 to be colored is carried out second time anodized, the organic solvents such as n-Amyl acetate or ultraviolet such as can be used to irradiate the chemical reactants such as liquid medicine (i.e. UV liquid medicine) removed by the coating material on described Part II, after anodized completes for the second time, continue to make the subsequent treatment such as sealing of hole to the described Part II 20 after oxidation.See the final effect figure that Fig. 3, Fig. 3 are the polychromatic surfaces after repeatedly anodized of the present invention.
In the present invention, the number of times of anodized is not limited to twice that the present invention proposes, and technical staff can select anodized number of times according to practical situation so that surface to be colored presents multiple color.
As it has been described above, the method that the oxidation describing the present invention in detail repeatedly colours, the present invention, by repeatedly anodized, is finally reached the effect of visually Rimless.Use this anodized mode, the bottleneck of secondary operations in prior art can be solved, it is achieved Rimless truly.
Another embodiment of the present invention, it is proposed that a kind of multi-colour metal surface, the method repeatedly coloured by above-mentioned anodic oxidation is obtained.
A further embodiment of this invention, a kind of portable electron device, including housing, described housing has by above-mentioned anodic oxidation repeatedly color method acquire multi-colour metal surface.
As mentioned above, describe in detail the present invention by the method that repeatedly colours of oxidation and multi-colour metal surface and the portable electron device comprising described polychromatic surface, use this anodized mode, the bottleneck of secondary operations of the prior art can be solved, it is achieved Rimless truly.
It should be appreciated that the above-mentioned detailed description of the invention of the present invention is used only for exemplary illustration or explains the principle of the present invention, and it is not construed as limiting the invention.Therefore, any modification, equivalent substitution and improvement etc. done in the case of without departing from the spirit and scope of the present invention, should be included within the scope of the present invention.Additionally, claims of the present invention be intended to fall in the equivalents on scope and border or this scope and border whole change and modifications example.
