Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
A case 100 according to an embodiment of the present application is described below with reference to fig. 1.
The housing 100 according to an embodiment of the present application, as shown in fig. 1 and 2, includes: a substrate 1 and a coating layer 2 formed on the edge region 12 by sputtering a coating material by shielding a part of the substrate 1 with a shielding plate 400. The substrate 1 comprises a central region 11 and an edge region 12 surrounding the central region 11. The width of the film coating layer 2 is 0-30mm, the inner edge and the outer edge of the film coating layer 2 are respectively an inner film ring 21 and an outer film ring 22, the thickness of the outer film ring 22 is larger than that of the inner film ring 21, and the thickness of the film coating layer 2 gradually changes from the edge region 12 to the central region 11 so as to gradually change the color.
It can be understood that the typical gradual color film is formed by adjusting the length of the shielding plate so that the thickness gradient of the coating film changes along the direction in which the target stands. Therefore, the color change of the casing is also gradually changed along the vertical direction of the target, the color of the casing cannot be gradually changed along the horizontal direction, and the gradual change coating film can not be formed only in the edge area and the gradual change gradient of the coating film thickness in the direction from the edge area to the central area can not be kept consistent. The shell 100 of the embodiment of the application forms the plated film layer 2 in the edge region 12 surrounding the central region 11, so that the color of the plated film layer 2 gradually changes from the edge region 12 to the central region 11.
And, general coating film gradual change effect is subject to the shielding piece size, and the shielding piece size is great to the distance of shielding piece and product is far away, and degree of control precision is general, is difficult to be at the arbitrary width surface accurate control gradual change degree of 0 ~ 30mm scope. In the shell 100 of the embodiment of the application, the width of the coating layer 2 is 0-30mm, and the gradual change degree of the coating layer can be accurately controlled on the surface of any width within the range of 0-30 mm.
According to the housing 100 of the embodiment of the application, the thickness of the plated film layer 2 is gradually changed from the edge region 12 to the central region 11 by the fact that the thickness of the film outer ring 22 is larger than that of the film inner ring 21. So that the coating layer 2 forms a gradually-colored film with gradually-decreasing thickness in the direction from the edge region 12 to the central region 11. In addition, the width of the coating layer 2 is 0-30mm, and the gradual change degree of the coating layer can be accurately controlled on the surface of any width within the range of 0-30 mm. Thereby, the gradual change form of the gradual change color film can be increased, which is beneficial to promoting the wide application of the shell 100.
In some embodiments, the plating layer 2 includes a primer layer, a first protective layer, a metal layer, and a second protective layer, which are sequentially stacked in a thickness direction, and the primer layer is disposed on the substrate 1. It can be understood that the setting of a plurality of retes not only can be convenient for promote the durability of coating film layer 2, also is convenient for regulate and control coating film layer 2's rete colour, is convenient for form the gradual change of more various retes.
The base layer can be a silicon-containing film layer, a zirconium-containing film layer, the first protective layer can be a silicon-containing film layer, a zirconium-containing film layer, a niobium-containing film layer, a titanium-containing film layer, an aluminum-containing film layer, etc., the metal layer can be an indium-containing film layer, a tin-containing film layer, an indium-tin-containing alloy film layer, a chromium-containing film layer, a niobium-containing film layer, a titanium-containing film layer, an aluminum-containing film layer, etc., and the second protective layer can be a silicon-containing film layer, a zirconium-containing film layer, a niobium-containing film layer, a titanium-containing film layer, an aluminum-containing film layer, etc. The good gradual change effect of the coating layer 2 can be realized, and the specific forms of the bottom layer, the first protective layer, the metal layer and the second protective layer are not limited.
In some embodiments, as shown in FIG. 1, the outer membrane ring 22 has a thickness of 30-300nm and the inner membrane ring 21 has a thickness of 0-50 nm. Therefore, the durability of the film layer of the coating layer 2 can be ensured, and a good color gradient effect can be formed.
In some embodiments, as shown in fig. 1, the brightness of the outer film ring 22 is greater than the brightness of the inner film ring 21, and the coating layer 2 has a gradual brightness change between the outer film ring 22 and the inner film ring 21. The coating 2 thus has a gradient in brightness in the direction of the edge region 12 towards the central region 11. Taking the example of the In (indium) plated film as an example, the brightness of the outer ring 22 of the film can reach about 90, and the brightness of the inner ring 21 of the film can reach about 30.
Optionally, the substrate 1 may be glass, ceramic, organic polymer, or the like, and the arrangement of the color-gradient film can be achieved, and the material of the substrate 1 is not limited herein.

The substrate 1 comprises a central region 11 and an edge region 12 surrounding the central region 11.
The coating layer 2 comprises a priming layer, a first protective layer, a metal layer and a second protective layer which are sequentially stacked in the thickness direction, and the priming layer is arranged on the edge region 12. The width of the film coating layer 2 is 0-30mm, the inner edge and the outer edge of the film coating layer 2 are respectively an inner film ring 21 and an outer film ring 22, the thickness of the outer film ring 22 is 30-300nm, the thickness of the inner film ring 21 is 0-50nm, the thickness of the outer film ring 22 is larger than that of the inner film ring 21, and the brightness of the outer film ring 22 is larger than that of the inner film ring 21. The thickness of the film coating layer 2 is gradually changed from the edge area 12 to the central area 11, so that the color is gradually changed, and the brightness of the film coating layer 2 is gradually changed between the outer film ring 22 and the inner film ring 21.
A method of manufacturing the case 100 according to an embodiment of the present application is described below with reference to fig. 2 to 6.
The method for manufacturing the housing 100 of the present application can realize the gradual change of the color of the housing 100 along the horizontal direction. The preparation method is similar to the processing method mentioned above in which the color of the shell is gradually changed along the vertical direction of the target, and the shielding plate is used, but the mode of using the shielding plate and the target is different, so that the gradient pattern formed on the shell is also different.
Specifically, in the processing method for gradually changing the color of the shell along the vertical direction of the target, a set of film thickness correction plate or correction sheet (the function of which corresponds to the shielding plate 400 in the application) is installed between the coating target (or evaporation source) and the coating product, the correction sheet forms a certain shielding on the coating area of the product, the shielding amount is adjusted by adjusting the length of the shielding sheet, the deposition thickness of the coating film in the area with a large shielding amount is small, the deposition thickness of the coating film in the area with a small shielding amount is relatively large, the step change of the length of the correction sheet causes the step change of the deposition thickness of the film layer on the surface of the product, and finally the appearance color with gradually changed surface of the product is formed. The method is difficult to control the gradient degree of the coating layer in a certain width range, and the color change of the product is also gradient along the vertical direction of the target material, and the gradient form is single.
The method for manufacturing the case 100 according to the embodiment of the present application, as shown in fig. 2 and 3, includes: a worktable 200 is provided, and the worktable 200 is rotatably arranged in the coating cavity. A substrate 1 is provided, the substrate 1 comprising a central region 11 and an edge region 12 surrounding the central region 11, the substrate 1 being provided on a table 200. A spacer 300 is provided, the spacer 300 being attached to the central region 11. A shield 400 is provided, the shield 400 being disposed on a side of the spacer 300 remote from the central region 11. Providing a coating source 500, wherein the coating source 500 is used for sputtering a coating material towards the edge region 12 to enable the coating material to be deposited on the edge region 12 to form a coating layer 2, the width of the formed coating layer 2 is 0-30mm, the inner edge and the outer edge of the coating layer 2 are respectively an inner film ring 21 and an outer film ring 22, the thickness of the outer film ring 22 is larger than that of the inner film ring 21, and the thickness of the coating layer 2 is gradually changed in the direction from the edge region 12 to the central region 11 to enable the color to be gradually changed.
It can be understood that, the spacer block 300 is arranged to form a gap with a fixed height between the substrate 1 and the shielding plate 400, so that the height of the gap is equal to the height of the spacer block 300, and the gradient of the gradual change of the film thickness can be conveniently adjusted and controlled by adjusting the height of the gap.
The shielding plate 400 is disposed on a side of the spacer 300 away from the central region 11 such that the shielding plate 400 is disposed adjacent to the substrate 1. In the general coating, the shielding plate is only arranged in the coating cavity but not adjacent to the substrate 1, so that the distance between the shielding plate and the substrate is easy to be far, the coating controllability is general, the coating accuracy is general, and the gradient degree is difficult to be accurately controlled on the surface with any width in the range of 0-30 mm.
In the preparation method of the housing 100 according to the embodiment of the present application, the working platform rotates to drive the substrate 1 to rotate synchronously during film coating. A single substrate 1 will pass in front of the coating source 500 once per revolution.
The manufacturing apparatus is capable of forming a circle of the coating layer 2 on the substrate 1 by the above manufacturing method, and manufacturing the housing 100 having a circle of the coating layer 2 with gradual change. Moreover, the inventor team has found through practice that in the film formed on the substrate 1 by the method, the thickness variation of the film within the range of 0-30mm from the central area 11 is obvious, and after the distance from the central area 11 exceeds 30mm, the thickness variation of the film is no longer obvious, so that the color of the film in the area is hardly changed. Therefore, the manufacturing method of the present application can be used to manufacture the housing 100 having a gradation width in the range of 0.30 mm.
The ability of the coating layer 2 to form a significant gradient in the width range of 0-30mm is mainly related to the manner in which the coating layer 2 is formed. This is because the sputtering direction of each point on the surface of the coating source 500 is divergent, but the divergence range is limited, the film material sputtered from a single point on the surface of the coating source 500 can be regarded as umbrella-shaped, the umbrella-shaped film material is overlapped by multi-point sputtering on the surface of the coating source 500, and when the shielding plate 400 is not provided, each point on the substrate 1 uniformly drops the material to form a uniform color film. However, when the substrate 1 is provided with the shielding plate 400 corresponding to the coating source 500, the shielding plate 400 shields the sputtered coating material umbrella. At the edge of the shielding plate 400, the final blanking on the edge region 12 of the substrate 1 is obviously changed due to the different shielding areas for the film material umbrellas from different points, so that the final plated film layer 2 forms a gradual layer. The edge of the shielding plate 400 does not work far from the central area 11, and especially when the distance from the central area 11 exceeds 30mm, even if a film layer is present, the thickness of the film layer does not change much, and the color gradient effect is almost zero.
Taking AE coating area in AB coating area (also called lower end area) of the substrate 1 as an example, it should be noted that point a is located on the outer ring 22 of the film and perpendicular to the length direction of the coating source 500, point B is located on the inner ring 21 of the film and perpendicular to the length direction of the coating source 500, and point E is located between point a and point B and flush with one edge of the shielding plate 400. As shown in FIG. 3, the arrows show the sputtering direction of the coating source, where the sputtering direction is divergent for each point on the surface of the coating source 500. As shown in FIG. 2, the arrows show the extent to which each of the zone coating sources 500 can sputter onto the substrate 1 due to the shielding effect of the shielding plate. In the AE coating region, the sputtering atoms on the surface of the MF region of the coating source 500 can be sputtered to the E point, and in the region above MF region, the sputtering path of the sputtering atoms is blocked by the blocking plate 400, and the sputtering atoms cannot reach the E point. Similarly, the sputtered atoms in the PF region of the film plating source 500 can be sputtered to point a, and the target atoms cannot be sputtered to point a in the region above the PF region due to the shielding plate 400. Therefore, the target area which can be sputtered to the point A is larger than the target surface area which can be sputtered to the point E, so that the deposition film thickness of the point A is thicker than that of the point E in the same time, and the deposition film thickness is gradually thinner from the point A to the point E, thereby realizing the gradual coating effect.
The principle of realizing the gradual change of the film thickness in the coating area from the point E to the point B is the same as that of the AE coating area, and the details are not repeated here.
The principle of realizing the gradual change of the film thickness in the plating area (also called the upper end area) symmetrical to the AB plating area is the same as that in the AB plating area, and the details are not described here.
The principle of realizing the gradual change of the film thickness in the left and right side areas of the substrate 1 is different from the principle of the upper and lower ends, as shown in the CD area in fig. 4, it should be noted that point C is located in the outer ring 22 of the film and parallel to the length direction of the film coating source 500, and point D is located in the inner ring 21 of the film and parallel to the length direction of the film coating source 500. In the process of coating, along with the rotation of the substrate 1, the included angle between the gap between the substrate 1 and the shielding plate 400 and the sputtering direction is changed ceaselessly, the existence of the shielding plate 400 also enables the deposition thickness of the coating film in the area close to the shielding plate to be smaller in the same time, and the deposition thickness of the coating film in the area far away from the shielding plate 400 to be larger in the same time, so that the deposition thickness of the coating film from C to D in the CD area is gradually reduced, and the gradual coating effect is realized.
In the description of the present application, it is to be understood that the terms "upper", "lower", "left", "right", "center", "length", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present application.
According to the method for manufacturing the housing 100 of the embodiment of the application, the coating material is sputtered by the coating source 500 toward the edge region 12, the shielding plate 400 is disposed adjacent to the substrate 1 to partially shield the coating material, so as to form the coated layer 2 on the edge region 12, and the thickness of the coated layer 2 is gradually reduced in the direction from the edge region 12 to the central region 11 to gradually change the color. Through setting up cushion 300 in order to form a gap of fixed height between base plate 1 and shielding plate 400 to the gradient of rete thickness gradual change can conveniently be regulated and control through the height of adjustment cushion, realize the gradual change degree at the arbitrary width surface accurate control rete of 0 ~ 30mm scope. The size of the coating region can be controlled by adjusting the size of the shielding plate 400. Thereby increasing the gradual change form of the gradual change color film and facilitating the wide application of the lifting shell 100.
In some embodiments, as shown in fig. 5, the spacer block 300 includes a positioning block 301 and a supporting block 302, the positioning block 301 may be fitted at the through hole of the substrate 1, and the supporting block 302 is used to be supported between the substrate 1 and the shielding plate 400. It can be understood that the positioning block 301 is arranged to facilitate accurate positioning of the spacer block 300, thereby improving the coating precision. The supporting block 302 is provided to improve the supporting stability of the spacer 300, thereby improving the operational reliability of the substrate 1 and the shielding plate 400.
In some embodiments, the height of the spacer 300 is 1-50 mm. By changing the height of the spacer 300 in this way, the gap height between the substrate 1 and the shielding plate 400 can be adjusted to adjust the gradient of the gradual film thickness change.
In some embodiments, as shown in fig. 6, the spacer 300 and the shielding plate 400 are integrally formed, and an adhesive layer is provided on the side of the spacer 300 close to the central area 11.

Here, an adhesive layer is disposed on a side of the pad 300 close to the central region 11, that is, an adhesive layer is disposed on a side of the integrated blocking piece 700 close to the central region 11, so that the adhesive layer can connect the integrated blocking piece 700 with the substrate 1, thereby improving the operational reliability of the integrated blocking piece 700 and the substrate 1.

The second template 602 is provided with a recessed area having the same shape as the substrate 1, and the substrate 1 is fitted in the recessed area. Thus, the substrate 1 can be fixed after being placed in the recessed area, the first mold plate 601 is used for positioning the relative position between the integrated stopper 700 and the substrate 1, the positioning portion 603 is arranged between the first mold plate 601 and the second mold plate 602, and the positioning block is used for fixing the positions of the first mold plate 601 and the second mold plate 602. Here, the adhesive layer between the substrate 1 and the integrated type blocking piece 700 may be a double-sided adhesive tape.
Further, one side of the loading jig 600 may be covered with a PET adhesive film. Here, one side of the PET film has adhesiveness, and the other side has no adhesiveness, and the side having no adhesiveness is attached to the loading jig 600, and the two are bonded by using a high temperature resistant double-sided tape. The substrate 1 can be adhered to the sticky surface of the PET film, and sufficient adhesion force between the substrate 1 and the PET film is guaranteed, so that the substrate 1 cannot fall off in the rotating process.
Of course, in some other embodiments, as shown in fig. 2, the loading jig 600 may also be a jig with a flat surface, and the substrate 1 is attached to the loading jig during the film coating process, so that the relative position of the substrate 1 is stable.
In some embodiments, as shown in FIG. 2, the block 300 and the shutter 400 may also be separate components. In the stage of mass production of products, after technological parameters are stable, the cushion block 300 can be automatically attached by a manipulator, so that the coating precision and efficiency can be improved, and the mass production is facilitated. For example, the common baffle plate and the cushion block are fixed manually, so that the fixing precision is low, the position deviation is easy to occur, and finally the size of a coating area is possibly influenced.
Specifically, both sides of the mat 300 may be adhered with a high temperature resistant double sided tape, and then the mat 300 is adhered to the central region 11. The number of the cushion blocks 300 can be multiple, for example, the number of the cushion blocks 300 can be four, and the position connection line of the four cushion blocks 300 can be rectangular or rhombic, which is beneficial to improving the operation stability of the cushion blocks 300.
Further, when the shielding plate 400 is attached, the shielding plate 100 is attached to the side, away from the central area 11, of the pad 300, and the position needs to be aligned when the shielding plate is attached, so that the shielding amount of the peripheral edge of the centerline area of the substrate can meet the requirement.
The size of the gradual-change coating area is changed by adjusting the size of the shielding plate 400, and the size of the shielding plate 400 can be as large as a product or each edge of the shielding sheet is 0-60 mm shorter than the corresponding edge of the product. The bottom surface of the pad 300 may be rectangular or circular, and the size of the bottom surface may be 0.2-0.4 square centimeters.
Optionally, the cushion block 300 can be replaced by a jig or a profiling jig, and good supporting and positioning effects can be achieved.
In some embodiments, as shown in fig. 2, the coating source 500 is a target and the coating layer 2 is formed by sputtering target atoms. It can be understood that the target material has low impurity content and high purity, and is convenient for improving the quality of the film layer. In addition, the high-density target has the advantages of good electric conductivity, good heat conductivity, high strength and the like, and is beneficial to reducing the sputtering power and improving the film forming rate.
In some embodiments, the coating source 500 sequentially sputters the coating material toward the edge region 12 multiple times, so that the coating material sequentially forms a stacked primer layer, a first protective layer, a metal layer, and a second protective layer on the edge region 12.
