Description

镜座、其制造方法及相机模组
技术领域
本发明涉及一种镜座、其制造方法及具有该镜座的相机模组。
背景技术
照相功能已经成为各种便携式电子产品例如手机及个人数字助理(PDA)不可或缺的主要功能之一。相机模组通常包括至少一个镜头模组，以及一个与镜头模组相对设置的影像感测器元件。镜头模组通常包括镜座、设置于镜座的镜筒、以及沿光轴方向依次固定于镜筒内的透镜组、间隔环和滤光片等光学元件。而影像感测器元件通常封装于镜座内，与镜头模组配合用于成像。
但是，现有的镜头模组的镜座的材料以塑料如PC/ABS(聚丙烯/丙烯腈-丁二烯-苯乙烯)工程塑料、聚四氟乙烯等居多，通常不具备良好的抗电磁波干扰能力，影像感测器元件容易受到外界电磁波的干扰而产生噪声，所述电磁波的干扰可以通过如Zhenguang Liang等人在2006年10月SPIE系统检测仪表与控制技术第六次国际研讨会(Sixth InternationalSymposium on Instrumentation and Control Technology)上发表的论文Radiatedelectromagnetic interference(EMI)measuring system中揭示的电磁干扰测量系统测得。所述电磁波的干扰导致无法获得清晰的图像，造成成像质量不佳。当成像解析度较高时，外界电磁波对影像感测器元件干扰所造成的对成像质量的影响就更为明显。
目前，可通过镀膜的方法在镜座的外表面形成一层铜/不锈钢抗电磁干扰涂层来降低电磁波对与镜头模组相配合的影像感测器元件的干扰，但此种方法需要昂贵的镀膜设备和真空系统。
发明内容
有鉴于此，有必要提供一种成本较低的镜座、其制造方法及相机模组。
一种镜座，该镜座的材料为主要由碳纳米管、碳黑及聚合物组成的具有抗电磁干扰功能的复合材料，所述碳纳米管和所述碳黑分散于所述聚合物中。
一种上述镜座的制造方法，其包括以下步骤：制备包含碳纳米管和碳黑的混合物；将所述包含有碳纳米管和碳黑的混合物与聚合物通过加热混合而使碳纳米管及碳黑分散于该聚合物中，得到主要由碳纳米管、碳黑及聚合物组成的具有抗电磁干扰功能的复合材料；以所述复合材料为原料，采用注射成型法得到该镜座。
一种相机模组，其包括：至少一镜片；一收容该至少一镜片的镜筒；一镜座；及一影像感测元件，该影像感测元件设置于镜座相对于镜筒的另外一侧，该镜座的材料为主要由碳纳米管、碳黑及聚合物组成的具有抗电磁干扰功能的复合材料，所述碳纳米管和所述碳黑分散于所述聚合物中。
相较于现有技术，该相机模组的镜座由具有良好的抗电磁波干扰能力的碳纳米管、碳黑及聚合物复合材料通过注塑成型法形成，可省去使用昂贵的镀膜设备和真空系统的步骤，成本较低。

图1是本发明实施例提供的相机模组的剖视图。
图2是图1的局部放大图。
具体实施方式
下面将结合附图，对本发明实施例作进一步的详细说明。
请参阅图1和图2，其为本发明实施例提供的一种相机模组100。该相机模组100包括若干镜片40，一收容该若干镜片40的镜筒10，镜座20，及影像感测元件50。其中，该镜筒10、镜座20、及若干镜片40构成一镜头模组。
该镜筒10的外壁设置有外螺纹。该镜座20包括一圆筒形部位202以及一与该圆筒形部位202相贯通的方框形部位204。该圆筒形部位202内壁设置有可与该镜筒10的外螺纹相啮合的内螺纹。
该影像感测元件50包括一影像感测器502以及一电路板504。该影像感测器502可以为电荷耦合器件(Charge Coupled Device，简称CCD)或互补金属氧化物半导体晶体管(Complementary Metal Oxide Semiconductor Transistor，简称CMOS)。该影像感测器502封装在所述电路板504上，并设置在该镜座20的方框形部位204内。
该影像感测元件50设置于镜座20相对于镜筒10的另外一侧。该影像感测元件50设置于镜座20中，即设置于镜座20的方框形部位204处。该影像感测器元件50可为电荷耦合元件(Charge Coupled Device，CCD)或者互补金属氧化物半导体元件(Complementary MetalOxide Semiconductor，CMOS)。
该镜座20的材料为主要由碳纳米管208、碳黑207及聚合物206组成的复合材料，所述碳纳米管208和所述碳黑207分散于所述聚合物206中，该碳纳米管208占该聚合物206的重量百分比为1.0％-15％，该碳黑207占该聚合物206的重量百分比为1.0％-10％。该聚合物206材料为聚碳酸酯(Polycarbonate)、聚碳酸酯/丙烯腈-丁二烯-苯乙烯(polycarbonate/Acrylonitrile Butadiene Styrene，PC/ABS)、聚碳酸酯/玻璃纤维(Polycarbonate/Glass fiber)、聚邻苯二甲酰胺(Polyphthalamide，PPA)、或聚苯醚(Polyphenylene oxide，PPO)。碳纳米管208可为单壁碳纳米管或多壁碳纳米管。

步骤二，将所述包含有碳纳米管208和碳黑207的混合物与聚合物206通过加热混合而使碳纳米管208及碳黑207分散于该聚合物206中，得到主要由碳纳米管208、碳黑207及聚合物206组成的具有抗电磁干扰功能复合材料。
步骤三，以所述复合材料为原料，采用注射成型法得到该镜座20。
相较于现有技术，该相机模组100的镜座20由具有良好的抗电磁波干扰能力的碳纳米管、碳黑及聚合物复合材料通过注塑成型法形成，可省去使用昂贵的镀膜设备和真空系统的步骤，成本较低。
另外，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思做出其他各种相应的变化，而所有这些变化都应属于本发明权利要求的保护范围。
