Description
Technical field
The present invention relates to the preparation technical field of the mesh base parts of mobile terminal, in particular to a kind of mesh of mobile terminal
The production method and mobile terminal of component.
Background technique
During mobile phone development, general earpiece, loudspeaker, the internal reinforcement steel disc with mesh and other need mesh to fill
For the relatively thin plate of the ratio of decorations after either by external force using a period of time, mesh area is easy collapse-deformation, a side
Face is since mesh area monomer intensity is bad, is on the other hand that moulding process causes mesh area itself that can make in preparation process
The defects of at corrugation, impression, fine crack, uneven thickness, excessively thin thickness.Especially as the prevalence of comprehensive screen mobile phone, with earpiece
For region, earpiece area is gradually transferred to on the cambered center or contact zone of mobile phone center and 2.5D radian screen
Domain, the former is to remove a part of volume on center to be used to accommodate earpiece mesh member, and the latter is each on mobile phone center and screen
It removes a part of volume to be used to accommodate earpiece mesh member, but earpiece mesh member is all mounted in the region with sterad, i.e.,
Non-face shape, in this way, which this requires earpiece mesh member is also space multistory shape；The mesh dress at many positions of mobile phone at present
Gadget is not usually flat shape to meet design requirement, still, to guarantee that appearance is set with cambered mesh decoration
Shape is counted, also to guarantee that mesh surface quality is good, mesh is uniform in size, thickness is uniform, mesh is not torn in forming process
Fine crack is generated, more stringent requirements are proposed to mold and forming technology.
But it currently, often will appear various defects during the preparation process for nonplanar mesh decoration, especially adopts
During being deformed into three-dimensional mesh member with die punch compacting plane net orifice, die punch and downtrodden mesh member surface are straight
Contact, metal thin-wall mesh member meeting injured surface quality in mold compacting process cause burr, and due to some nets
The mesh area thickness of hole decoration only has 0.25mm, than relatively thin, is also easy to cause corrugation, impression, fine crack, uneven thickness
The defects of.
Therefore, need now it is a kind of can solve drawbacks described above preparation method realize prepare meet demand mesh dress
Gadget.
Summary of the invention
