All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the embodiments of the present invention, it should be understood that the terms "lateral," "width," "thickness," and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used for convenience in describing the present invention and simplifying the description, but do not imply or indicate that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention.
The following will describe the method for processing the clearance area of the housing according to the embodiment of the present invention in detail with reference to fig. 1 to 2.
Fig. 1 is a schematic flow chart of a method for processing a clearance area of a housing according to an embodiment of the present invention. As shown in fig. 1, the method of the embodiment of the present invention may include the following steps S101 to S113.
S101: providing a shell, wherein the shell is made of a signal shielding material and is provided with a preset area, and the preset area comprises a first surface and a second surface which are arranged oppositely.
Specifically, the housing is manufactured according to actual requirements, and it can be understood that the housing can be a back cover of the mobile terminal. The preset area is arranged in a certain area of the shell according to actual requirements, and the preset area is a certain area on the shell, which needs to pass through radio frequency signals. The first surface is the inner side surface of the back cover, the second surface is the outer side surface of the back cover, and the outer side surface is exposed in the air, namely the surface which can be directly contacted by a user. Of course, in other embodiments, the housing may also be a front case of the mobile terminal or a rear cover with a bezel.
Preferably, the housing is made by: putting a metal plate into a die to be stamped into a metal plate with a preset shape; and processing the internal structure and the external shape of the metal plate with a preset shape on a numerical control machine tool to obtain the shell. The method comprises the following steps of cutting a large aluminum plate into small aluminum plates, putting the cut small aluminum plates into a die, and stamping to form the metal plate with a preset shape, wherein the metal plate is an aluminum plate, and the stamping frequency of the aluminum plate can be one time or multiple times of continuous stamping; and processing the metal plate on a numerical control machine tool to form the required shell.
S103: at least one support structure is machined.
Specifically, at least one supporting structure is machined on the first surface of the preset area, so that the supporting structure is arranged on the first surface in a protruding mode. The supporting structures are three and are sequentially arranged on the first surface of the clearance area along the transverse direction of the shell, namely the width direction, at intervals, namely the inner side surface, so that when the subsequent supporting structures are cut and removed, traces left on the first surface are in the mobile terminal, and the mobile terminal needs to be detached to be observed, and the appearance integrity of the mobile terminal cannot be influenced. It will be appreciated that the support structure is pier-like to prevent deformation of the shell during laser cutting. Of course, in other embodiments, the support structure may be other structures as long as they support, for example, the support structure is a rib or rib. Of course, in other embodiments, the number of support structures may be other.
S105: the laser cuts a plurality of micro-slits and/or a plurality of micro-holes.
Specifically, the laser cutting machine is aligned to the second surface of the preset area, the laser cutting machine gradually cuts a plurality of micro-slits and/or a plurality of micro-holes in the preset area, the micro-slits and/or the micro-holes are arranged to form a preset mark, and the at least one supporting structure spans the preset area so as to connect the shell into a whole. Wherein, the laser of laser cutting machine penetrates the second surface from the first surface and cuts a plurality of micro-gaps and/or a plurality of micropores gradually, and it can be understood that, the quantity of micro-gaps and micropores is set correspondingly according to the preset mark formed by the required arrangement. That is, the preset mark may be formed by arranging a plurality of micropores only, may be formed by arranging a plurality of micro-slits, or may be formed by arranging a plurality of micro-slits and a plurality of micropores simultaneously.
It can be understood that the preset mark can be a character mark; or the preset mark is a pattern mark; or the preset mark is a mark formed by patterns and characters. In order to further improve the utilization of the preset mark, the structure of the shell is optimized, and the preset mark is a product trademark mark; or the preset mark is a product model mark. The preset mark is taken as an example of a product trademark mark. For example, the preset mark is a logo corresponding to the mobile terminal, for example, the logo of the mobile terminal is "a", the multiple micro-slits and the multiple micro-holes are arranged in a stroke of "a", and the preset mark not only can be used as a clearance area of the housing to radiate radio frequency signals, but also can be used as an unavoidable mark on the mobile terminal, so that the structure of the housing is optimized.
It is understood that the micro-slits may be linear, curved, or irregular, and the micro-holes may be elliptical or circular, etc. according to the desired predetermined mark. Wherein, when the laser cuts a plurality of micro-slits and/or a plurality of micropores, the cut part is not completely cut off. For example, the laser cutting may be performed by using a plurality of micro-slit bands, each micro-slit band includes a plurality of micro-slits, the micro-slits in the micro-slit band extend along the contour line of the predetermined mark, and a material of the predetermined region is retained between each micro-slit band, so that the predetermined region is maintained as a connected region through the gap between the micro-slit bands. When the micro holes are cut, the micro holes are formed at intervals on the predetermined region, so that the predetermined region is maintained as a communicating region by the gaps between the micro holes. It is understood that the plurality of micro-slits and/or the plurality of micro-holes are uniformly spaced to form the predetermined mark, that is, the distance between two adjacent micro-slits, two adjacent micro-holes, or the distance between two adjacent micro-slits and micro-holes is the same.
Specifically, the inventors have conducted a great deal of experiments to study that the processing method in the embodiment of the present invention can make the width of the slit or the diameter of the micro hole of the micro slit smaller than 0.3mm, and preferably, the width of the slit or the diameter of the micro hole of the micro slit is 0.05mm to 0.15mm, in this embodiment, the width of the slit or the diameter of the micro hole of the micro slit is 0.06mm, which is hardly visible to the naked eye, so as to ensure that the radio frequency signal of the antenna in the mobile terminal can pass through and improve the integrity of the appearance of the housing. Each support structure spans the preset mark, namely the preset mark is shielded, so that a good support structure is formed. Of course, in other embodiments, the width of the micro-slit and the diameter of the micro-hole may be 0.05mm or 0.15mm, among other dimensions.

Specifically, after the preset mark is machined on the shell, burrs or dirt may exist inside, outside or on the peripheral surface of the preset mark, and the surface of the shell is treated in order to facilitate filling of micro-seams and micro-holes in the preset mark of the shell. It will be appreciated that the removal of burrs and dirt from the shell facilitates subsequent filling of the micro-seams and micro-holes of the shell, further improving the appearance integrity of the shell. Of course, in other embodiments, this step may be omitted.
S109: and carrying out Nano (NMT) injection molding filling on the plurality of micro-gaps and/or the plurality of micro-holes so as to fill non-signal shielding materials in each micro-gap to obtain a clearance area.
Specifically, the housing having the clearance area is subjected to an etching process. Wherein the non-signal shielding material is a material capable of passing radio frequency signals, it is understood that the non-signal shielding material may be plastic, wherein a plurality of micro-slits and a plurality of micro-holes are Nano (NMT) injection-molded and filled to obtain a clearance area. The plurality of micro-slits and the plurality of micro-holes filled with the non-signal shielding material can form a clearance area of the antenna through a radio frequency signal of the antenna, namely, a preset mark.
S111: the housing with the clearance area is surface treated.
Specifically, the shell with the clearance area is subjected to surface polishing, sand blasting and anodic oxidation to form a multi-color appearance effect, and the performance of the shell is further improved. Of course, in other embodiments, this step may be omitted.
S113: the support structure is cut away.
Specifically, the support structure is cut away by a numerically controlled machine tool.
According to the processing method of the clearance area of the shell, provided by the embodiment of the invention, the micro-slits and/or the micro-holes are gradually formed in the preset area, finally the micro-slits and/or the micro-holes are arranged into the preset mark along with the cutting path of the laser, and meanwhile, the non-signal shielding material is filled in the micro-slits and the micro-holes, so that the preset mark not only can pass through a radio frequency signal, but also can be a mark on the mobile terminal, the structures of the shell and the mobile terminal are optimized, and the use of the non-signal shielding material of the shell is reduced due to the narrow micro-slits or micro-holes, and the appearance integrity of the shell is ensured.
