Referring to fig. 1, fig. 1 is a flowchart illustrating a method for manufacturing a housing according to a preferred embodiment of the present application. The shell is processed by a metal substrate. The outer surface of the shell is formed by a plurality of curved surfaces, so that the shell is round and smooth in appearance, and user experience is improved. It is understood that the housing is applied to a mobile terminal, which may be a mobile phone, a tablet computer, a notebook computer, or the like. The metal shell has a shielding effect on electromagnetic waves, and an internal antenna of the mobile terminal applied to the shell cannot receive and transmit electromagnetic wave signals. In order to seal the housing, the micro-slits are filled with a sizing material that does not affect reception and transmission of electromagnetic waves, thereby achieving sealing of the housing. In this embodiment, the housing is a back cover of the mobile phone. The method for manufacturing the shell includes, but is not limited to, step S100, step S200, step S300, step S400, step S500, step S600 and step S700, and each step is described in detail as follows.
Step S100, providing a housing base 100, where the housing base 100 includes a first surface 100a and a second surface 100b that are disposed opposite to each other. Referring to fig. 2, fig. 2 is a schematic structural diagram of a housing substrate 100 used in the housing manufacturing method of the present application. The material of the housing base 100 is metal, for example, the material of the housing base 100 may be, but is not limited to, aluminum alloy.
Step S200, forming antenna micro-gaps penetrating the first surface 100a and the second surface 100 b.
Step S300, filling glue into the antenna micro-seam to form a first sealing layer 200. Referring to fig. 3, fig. 3 is a schematic structural diagram illustrating a first sealing layer 200 formed in the method for fabricating a housing according to the present application.
Step S400, a first sealant layer 200 is formed and simultaneously a glue is coated on a predetermined region of the first surface 100a to form a first cover layer 300. Referring to fig. 4, fig. 4 is a schematic structural diagram illustrating the formation of the first sealing layer 200 and the first covering layer 300 in the method for manufacturing the housing of the present application.
Step S500, the first cover layer 300 is processed into a pattern with a preset shape to obtain a second cover layer 310. Referring to fig. 5, fig. 5 is a schematic structural diagram illustrating a second cover layer 310 formed in the method for manufacturing a housing according to the present application. In fig. 5, the predetermined shape of the pattern is illustrated as a hollow O.
Step S600, performing a surface treatment on an area of the housing base 100 not covered by the second cover layer 310 to change brightness. The surface treatment is performed on the area of the housing base 100 not covered by the second cover layer 310, so as to change the brightness, and may be: the area of the case base 100 not covered by the second cover layer 310 is surface-treated to reduce brightness. For example, the area of the housing substrate 100 not covered by the second cover layer 310 is subjected to a matte treatment, so that the brightness of the area of the housing substrate 100 not covered by the second cover layer 310 is reduced. It is understood that, the surface treatment is performed on the area of the housing base 100 not covered by the second cover layer 310, and the brightness may be changed as follows: increasing the brightness of the area not covered by the second cover layer 310.
Step S700, removing the second cover layer 310 to form the pattern of the preset shape on the housing base 100. Since the area of the housing base body 100 not covered by the second cover layer 310 is subjected to surface treatment in the housing manufacturing method of the present application, and the brightness of the area not covered by the second cover layer 310 is changed, after the second cover layer 310 is removed, there is a difference between the brightness of the portion of the housing base body 100 covered by the second cover layer 310 and the brightness of the area covered by the second cover layer 310, so that a pattern in a preset shape is formed on the housing base body 100. In this embodiment, the pattern with the preset shape may be an identifier (logo) of a terminal manufacturer of the mobile terminal to which the housing is applied, or may be another identifier.
Compared with the prior art, in the case manufacturing method of the present application, when the glue is filled into the antenna micro-gap, the glue is covered on the preset area of the first surface 100a to form the first cover layer 300 while the first sealing layer 200 is formed, the first cover layer 300 is processed into the pattern with the preset shape to obtain the second cover layer 310, the area of the case substrate 100 not covered by the second cover layer 310 is subjected to surface treatment to change the brightness, and therefore, after the second cover layer 310 is removed, the brightness of the area covered by the second cover layer 310 is different from that of the area not covered by the second cover layer 310, and thus, the pattern with the preset shape is formed on the case substrate 100. Therefore, according to the shell manufacturing method, the filling of the rubber material into the antenna micro-gap and the covering of the rubber material on the preset area of the first surface 100a can be completed in the same process, so that the process of manufacturing the shell is saved, and the processing efficiency of the shell is improved.
In one embodiment, the step S700 includes: the second cover layer 310 is peeled off to form the pattern of the predetermined shape on the case base 100. Preferably, before peeling the second cover layer 310, the step S700 further includes: the second cover layer 310 is treated from the edge of the second cover layer 310 to reduce the adhesion property of the second cover layer 310 to the case base 100. The second cover layer 310 may be easily peeled off from the case base 100 by treating the second cover layer 310 from the edge of the second cover layer 310 to reduce the adhesion of the second cover layer 310 to the case base 100.
In an embodiment, between the step S200 and the step S300, the method for manufacturing the housing further includes, but is not limited to, the step a, the step b, and the step c, and each step is described in detail as follows.
Step a, judging whether the distance between the preset area and the antenna micro-seam is smaller than a preset distance. When the distance between the preset area and the antenna micro-seam is smaller than the preset distance, entering the step b; and c, entering the step c when the distance between the preset area and the antenna micro-seam is greater than or equal to the preset distance. It is understood that, when the distance between the preset region and the antenna micro-gap is smaller than the preset distance, the distance between the preset region and the antenna micro-gap may be considered to be relatively close; when the distance between the preset region and the antenna micro-gap is greater than or equal to the preset distance, the distance between the preset region and the antenna micro-gap can be considered to be relatively long. For example, the predetermined distance may be, but is not limited to, 3 cm.
And b, when the gap between the preset area and the antenna micro-gap is smaller than a preset distance, forming a complete area by the first covering layer 300 and the first sealing layer 200.
And c, when the gap between the preset area and the antenna micro-gap is greater than or equal to a preset distance, forming two independent areas by the first covering layer 300 and the first sealing layer 200.
In an embodiment, between the step S200 and the step S300, the method for manufacturing a housing further includes: the first surface 100a is cleaned to remove oil from the first surface 100 a.
Preferably, when the antenna micro-gap is filled with the sizing material, air is blown into the antenna micro-gap to accelerate the flow of the sizing material into the micro-gap. Preferably, when the antenna micro-gap is filled with the sizing material, the colloid filled in the antenna micro-gap is blown along the extending direction of the gap. This allows the glue to flow in the direction of extension of the antenna slot, thereby filling the glue into the antenna slot quickly. Preferably, when the antenna micro-gap is filled with the glue, the glue is pressurized to discharge air bubbles in the glue, so as to improve the sealing performance of the first sealing layer 200 formed by the glue.
Preferably, when the glue is filled into the antenna micro-gap, air is blown into the antenna micro-gap, and the glue filled in the antenna micro-gap is pressurized. When the rubber material is rapidly filled into the antenna micro-gap, air bubbles of the rubber material filled in the antenna micro-gap are discharged, and the sealing performance of the first sealing layer 200 formed by the rubber material is improved.
Preferably, between the step S200 and the step S300, the method for manufacturing a housing further includes: and carrying out surface roughening treatment on the side wall of the antenna micro-slit. The side arm of the antenna micro-slit is roughened by the following method: and forming a plurality of nanoscale pits on the side walls of the antenna micro-slots. After the surface roughening treatment is performed on the side wall of the antenna micro-gap, when the step S300 fills the rubber material into the antenna micro-gap to form the first sealing layer 200, the first sealing layer 200 is bonded to the side wall more tightly.
In the present embodiment, the step S300 includes a step S310 and a step S330, and each step is described in detail as follows. Referring to fig. 6, fig. 6 is a schematic flowchart of the step S300 of the present application.
Step S310, filling a first adhesive into the antenna micro-gap from the side where the first surface 100a is located, and curing the first adhesive to form a first sub-sealing layer.
Step S330, filling a second glue into the antenna micro-gap from the side where the first surface 100a is located, covering the first sub-sealing layer, and curing the second glue to form a second sub-sealing layer.
In one embodiment, the first and second sizes are both liquid sizes, and the viscosity of the first sub-size is less than the viscosity of the second size. The viscosity of the first rubber compound is smaller than that of the second rubber compound, so that the first rubber compound has better fluidity than the second rubber compound, and after the first rubber compound is filled in the antenna micro-gap, the first rubber compound can fully flow in the antenna micro-gap to be filled at the bottom of the antenna micro-gap, so that bubbles at the bottom of the antenna micro-gap are prevented from being generated, the quality of the first sub-sealing layer is improved, and the overall performance of a shell of the mobile terminal is improved.
Preferably, the loading of the primary compound is less than the loading of the secondary compound. After the first rubber material is filled, due to the fact that the filling amount of the first rubber material is small, more spaces are formed in the antenna micro-gaps, the first rubber material can better flow in the antenna micro-gaps, the first rubber material can flow to any corner of the bottoms of the antenna micro-gaps, and after the first sub-sealing layers are formed, the first sub-sealing layers can be tightly attached to the bottoms of the antenna micro-gaps, so that the defects of the antenna micro-gaps, air bubbles and the like between the first sub-sealing layers and the bottoms of the antenna micro-gaps are reduced, and the problems that the first sub-sealing layers crack or glue leakage and the like are caused by the defects of the antenna micro-gaps, the air bubbles and the like are avoided. Specifically, the filling mass of the first rubber compound may be 0.1 to 0.8 times the filling mass of the second rubber compound.
The first size may be cured by a heat curing process or an ultraviolet light curing process. In the process of curing the first sizing material through a heating curing process, the temperature of the heat curing can be 80-110 ℃, the temperature is selected as low as possible to be suitable for curing, so as to avoid the phenomenon that the first sizing material cracks or shrinks and deforms or is separated from the inner peripheral wall of the antenna micro-slot due to overhigh curing temperature. Optionally, the time for thermal curing may be 0.5-2 h. If the curing time is too short, the primary rubber compound may not be completely cured, and if the curing time is too long, the primary rubber compound may crack and deform.
Preferably, the step S300 further includes a step S320 between the step S310 and the step S330, and the step S320 is described in detail as follows.
Step S320, reducing the first sub-sealing layer to a preset temperature. In this embodiment, the first sub-seal layer is cooled to 20-40 ℃. In the process of filling the second adhesive material, when the second adhesive material contacts the cooled first sealing layer 200, if the temperature of the cooled first sealing layer 200 is too high, the temperature of the second adhesive material may be suddenly increased, so that the flowability and shrinkage of the second adhesive material are affected, the adhesiveness between the first sealing layer 200 and the antenna micro-gap is further affected, and the performance of a finally formed housing is further affected.
Further, in the process of cooling the first sealing layer 200, the cooling rate of cooling the first sealing layer 200 may be 0.1-0.8 ℃/min, and the cooling is performed at a slow speed, so as to ensure that no shrinkage or less shrinkage occurs in the cooling process of cooling the first sealing layer 200, and further ensure that the cooled first sealing layer 200 is always attached to the inner wall of the antenna micro-gap and the adhesiveness between the first sealing layer 200 and the antenna micro-gap.
In the present application, an antenna micro-gap penetrating through the first surface 100a and the second surface 100b is formed on the housing base 100 as an example for illustration and description, and it can be understood that, when the housing includes a plurality of antenna micro-gaps, the detailed description of filling the antenna micro-gaps with the rubber material to form the first sealing layer 200 may be referred to for filling the antenna micro-gaps with the rubber material, and details are not repeated here.
