具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的若干实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体地实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
市场上的摄像头模组一般包括镜头、镜座和影像传感器组件，如何将上述各组件良好的结合起来，并保证光学性能的要求，以及机械组装的位置关系，一直是相关技术人员研究的方向。相关技术的装配方式是先将影像传感器通过表面贴装技术(Surface Mounted Technology，SMT)贴合于电路板，接着将镜座与影像传感器组件通过打胶连接，镜头和镜座通过螺丝连接，再通过自动调焦技术来微调镜头位置，使镜头焦点落在影像传感器的中心，以及通过自动调心技术使镜头光轴与影像传感器中心法线重合。
然而，申请人经研究发现上述装配方式中存在较多不足。第一方面，由于镜座与影像传感器组件、镜头都是通过打胶的方式来固定，这种方式完全依赖胶水粘接力的强度，导致容易出现影像传感器组件脱落的隐患。在装配摄像头模组过程中，打胶后的胶水不做其他处理，导致胶水容易与其他组件摩擦而掉落残渣，从而会对影像传感器等器件造成污染，影响成像质量。此外，点胶存在难度，胶水的量也不易控制。
第二方面，由于电路板容易因温度变化而变形翘曲导致平整度较低，且影像传感器有本体公差及SMT的贴片公差，由此导致安装在电路板的影像传感器的位置一致性较差。为了保证镜头焦点落在影像传感器的中心，以及镜头的光轴与影像传感器的中心法线重合，需通过自动调焦技术与自动调心技术来对镜头进行调整，这样将会导致镜头光轴相对于镜座的定位柱基准不一致，造成了成批生产的摄像头模组出现镜头歪斜不一致的问题，而客户安装时的基准是以镜座的定位柱为基准，造成模组在组装到成品设备上出现光学性能不佳的问题。
因此，需要设计一款镜头光轴与镜座基准和影像传感器中心法线相对位置度精确度高的摄像模组结构，以及优化一种能使镜头与镜座和影像传感器组件结合强度高、安装方便、不易脱落，也不会对影像传感器等器件造成污染，影响成像质量的摄像头模组组装方式。
请参阅图1，所示为本发明实施例提供的一种摄像头模组10的爆炸示意图，用于有特殊定位基准要求的摄像头模组，模组中镜头光轴需要与影像传感器法线重合，而且要满足相对于定位基准的尺寸要求。
具体地，在本实施例中，摄像头模组10包括镜头100、镜座200、影像传感器组件300和防松脱螺丝。镜座200用于装配镜头100。影像传感器组件300贴合安装于镜座200。防松脱螺丝用于将镜头100固定安装于镜座200，以及固定镜座200与影像传感器组件300。
具体地，在本实施例中，请参阅图2，所示为本发明实施例提供的镜头100的结 构示意图，镜头100包括外周壁106、外螺纹103、定位导向台阶102与限位环101，外螺纹103、定位导向台阶102与限位环101均设置于外周壁106，外螺纹103、定位导向台阶102与限位环101均设置于镜头100的外侧面。定位导向台阶102位于外螺纹103与限位环101之间。限位环101大致设置于镜头100的中部，限位环101自定位导向台阶102向外凸出，限位环101包括第三表面104与第四表面105，第三表面104与第四表面105相背。外螺纹103自镜头100的外侧面的一端朝定位导向台阶102的方向延伸。其中，本申请实施例关于方位的术语，例如“中部”等术语以图中结构之间的相对位置作为参考标准。
本实施例通过设置定位导向台阶102，以保证镜头顺利的旋入镜座200的镜头装配孔中。本实施例通过设置自定位导向台阶102向外凸出的限位环101，以保证镜头100在旋入镜座200后停止到合适的位置，避免成批产品镜头后焦尺寸不一致。
具体地，在本实施例中，请参阅图3，所示为本发明实施例提供的镜座200的剖面示意图，镜座200包括第一表面207与第二表面208，第一表面207与第二表面208相背。镜座200还包括内周壁210，内周壁210限定形成镜头装配孔，镜头装配孔自第一表面207贯穿第二表面208。镜座200开设有螺钉孔，螺钉孔用于安装防松脱螺丝，螺钉孔包括第一螺钉孔202和第二螺钉孔206，第一螺钉孔202开设于第一表面207，第一螺钉孔202与镜头装配孔相交。第一螺钉孔202的数量大于或等于两个，本实施例中，第一螺钉孔202的数量为两个，两个第一螺钉孔202环绕镜头装配孔设置。第二螺钉孔206开设于第二表面208，第二螺钉孔206与镜头装配孔间隔。第二螺钉孔206的数量大于或等于一个，本实施例中，第二螺钉孔206的数量为三个，三个第二螺钉孔206环绕镜头装配孔设置。
