附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍,显而易见地,下面描述中的附图是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
在介绍本发明实施例提供的技术方案前,先对技术方案涉及的一些相关内容进行说明:目前,模内注塑、激光直接成型技术(英文:Laser Direct Structuring,缩写:LDS)、纳米成型技术(英文:Nano Molding Technology,缩写:NMT)以及ABS材料表面电镀制作工艺已经是业界应用非常成熟的技术。
模内注塑技术是指将金属件放入模具中然后注塑,最后金属件和塑件结合在一起。
LDS技术是指在成型的塑胶件支架上,利用激光镭射技术激活塑胶材料中的催化成分,通过化学镀处理在激活后的塑胶表面形成金属镀层。LDS能为普通的塑料元件赋予电气互连功能、支撑元器件功能和塑料壳体的支撑、防护等功能,以及由机械实体与导电图形结合而实现的屏蔽、天线等功能。LDS材料是一种内含有机金属复合物的改性塑胶,激光照射后,使有机金属复合物释放出金属粒子。
NMT技术是指将金属与塑胶以纳米技术结合的工艺技术,先将金属表面经过纳米化处理后使金属表面形成纳米级微孔,塑胶材料注塑后进入微孔与金属结合。NMT可以让金属与塑胶一体成型,不但能够兼顾金属外观质感, 也可以简化产品机构件设计。
ABS材料表面电镀制作工艺,适用于在ABS材料元件的表面形成多重金属层,首先形成一导电介质于元件的表面,接着以化学镀的方式,形成一化学金属层(如化学铜层或化学镍层)于塑料元件的表面,然后调整元件表面的材料特性,接着以电解电镀的方式,形成一电镀金属层(如电镀铝层、电镀镍层或电镀铬层)于化学金属层的表面。该制作工艺除可达到局部电镀的目的之外,其电镀金属层更具有高结构强度及高导电度,同时可使元件能保留其材质的原有特性。
化学镀也称无电解镀或者自催化镀,是在无外加电流的情况下借助合适的还原剂,使镀液中金属离子还原成金属,并沉积到零件表面的一种镀覆方法。化学镀是在金属的催化作用下,通过可控制的氧化还原反应产生金属的沉积过程。目前,化学镀已在电子、阀门制造、机械、石油化工、汽车、航空航天等工业中得到广泛的应用。一般的,化学镀处理可以是化学镀铜、化学镀镍、化学镀铬、化学镀锡、化学镀金或化学镀银等等,具体实施时根据实际需求来选择。
为了使本领域技术人员能够更清楚地理解本发明实施例提供的技术方案,下面通过具体的实施例进行详细说明:
本发明的实施例提供的电子设备外壳的加工方法,该电子设备外壳包括金属壳体以及用于隔断该金属壳体的隔断条,如图2所示,该方法包括:
步骤10、在该隔断条表面的预设区域形成预设金属层,其中,该隔断条表面除预设区域以外的区域为绝缘区。
具体的,该隔断条与金属壳体可以是通过模内注塑技术进行结合的、或该隔断条与金属壳体还可以是通过纳米成型技术NMT进行结合的、或该隔断条与金属壳体还可以是通过组装工艺进行结合的。
该隔断条的材料包括:可利用LDS加工的LDS材料、表面印刷或喷涂有可镭雕激活的活化成分的塑胶材料、或者ABS材料。
示例性的,以该隔断条的材料为LDS材料或表面印刷或喷涂有可镭雕激活的活化成分的塑胶材料为例,且化学镀处理选为化学镀铜,如图3所示,步骤10中的在该隔断条表面的预设区域形成预设金属层具体可以包括:
步骤101、对该隔断条表面的预设区域进行镭雕处理。
示例性的,对如图2所示的隔断条表面的预设区域进行激光镭雕处理,图2中预设区域以外的区域也即绝缘区的宽度为0.1~0.2mm,通过镭雕激活预设区域材料的化学镀功能。
需要说明的是,隔断条的形状可以是规则的线性、环形,也可以是其他不规则的图形,图2所示的隔断条的形状仅仅是示意性的,隔断条的形状具体由技术人员根据实际需求选择,本发明对此并不做限定。
步骤102、对镭雕处理后的预设区域进行化学镀铜,使得在预设区域对应的材料上形成铜层。
化学镀铜已经是现有的应用很成熟的技术,对镭雕处理后的预设区域进行化学镀铜具体为:通过甲醛还原铜反应,铜附着在镭雕处理后的预设区域表面,一般要求铜层厚度达到10um以上。需要特别说明的是,当该隔断条与金属壳体是通过模内注塑技术进行结合的或该隔断条与金属壳体是通过NMT进行结合的时,可以为电子设备外壳进行通电以阻止对金属壳体进行化学镀铜。当该隔断条与金属壳体是通过组装工艺进行结合的时,可以单独对隔断条进行处理,在对隔断条的预设区域化学镀铜时并不牵涉金属壳体。
步骤103、对镀有铜层的材料进行电镀处理,使得在铜层上形成预设金属层。
需要说明的是,一般的,金属壳体的金属材料一般为不锈钢或铝,如果金属壳体是不锈钢的,则金属壳体表面以及隔断条表面预设区域镀镍,镀镍后的效果与不锈钢喷砂后的效果很接近;如果金属壳体是铝的,那么预设金属层的金属材料也选为铝,通过电镀处理在铜层表面镀铝,一般要求铝厚度达到0.1mm以上。
值得一提的是,化学镀铜是自然沉积附着,表面粗糙,电镀则通过电流实现强制电子交换,镀层致密,可以实现光亮的表面效果。
最后,对预设区域电镀铝后形成的铝层与铝质的金属壳体进行喷砂或者阳极氧化处理以实现整体一致的金属化效果。
示例性的,图4a所示为隔断条的局部放大后的结构示意图,其中,隔断条表面除预设区域外有四条宽度0.1~0.2mm绝缘带,绝缘带仍是塑胶材料,用于隔断天线及主壳体,弱化天线耦合效应,达到等效于完全断开的效果,在实现外壳一体化金属效果的同时保证天线的性能。图4b为电 子设备外壳的局部放大后的结构示意图,其中,虚线部分为放大后的绝缘带。
另外,以该隔断条的材料为ABS材料为例,其中,假设金属壳体的金属材料为铝,预设金属层的金属材料也选为铝,且化学镀处理选为化学镀铜,如图5所示,步骤10中的在该隔断条表面的预设区域形成预设金属层具体可以包括:
步骤201、对该隔断条表面进行化学镀铜,使得在该隔断条表面形成铜层。
示例性的,参照上述对ABS材料表面电镀制作工艺的说明,为该隔断条表面完成镀铜。需要特别说明的是,当该隔断条与金属壳体是通过模内注塑技术进行结合的或该隔断条与金属壳体是通过NMT进行结合的时,可以为电子设备外壳进行通电以阻止对金属壳体进行化学镀铜。当该隔断条与金属壳体是通过组装工艺进行结合的时,可以单独对隔断条进行处理,在对隔断条的预设区域化学镀铜时并不牵涉金属壳体。
步骤202、对该隔断条表面附着的铜层进行电镀处理,使得在铜层上形成预设金属层。
示例性的,参照步骤103中的说明,为隔断条表面附着的铜层上镀铝。
步骤203、将该隔断条表面上覆盖在除预设区域以外的区域的预设金属层以及铜层去除。
具体的,可以利用镭雕去除该隔断条表面上覆盖在除预设区域以外的区域的预设金属层以及铜层。
需要说明的是,由于步骤202是对隔断条的表面全部镀铝,通过激光镭雕蒸发的方式去除掉该隔断条表面上覆盖在除预设区域以外的区域的铝层和铜层使该区域成为绝缘区。
最后,对预设区域电镀铝后形成的铝层与铝质的金属壳体进行喷砂或者阳极氧化处理以实现整体一致的金属化效果。
示例性的,图4a所示为隔断条的局部放大后的结构示意图,其中,隔断条表面除预设区域外有四条宽度0.1~0.2mm绝缘带,绝缘带仍是塑胶材料,用于隔断天线及主壳体,弱化天线耦合效应,达到等效于完全断开的效果,在实现外壳一体化金属效果的同时保证天线的性能。图4b为电 子设备外壳的局部放大后的结构示意图,其中,虚线部分为放大后的绝缘带。
