技术领域
本申请涉及光学镜头领域，具体地，本申请涉及光学镜头、摄像模组及其制造方法。
背景技术
随着科技水平的不断发展进步，移动电子设备日益普及，用于移动电子设备来帮助使用者获取影像(例如视频或者图像)的可成像光学器件的相关技术得到了迅猛的发展和进步，并且在诸如医疗、安防、工业生产等诸多的领域都得到了广泛的应用。
为了满足消费者对于拍照不断提高的需求，自动对焦的摄像模组广泛应用于数码产品中，例如智能手机、平板电脑、监控等终端设备，并呈现出快速发展的趋势。
现在，数码产品朝着小型化、高性能化的趋势发展，相应的对于光学镜头的体积和性能提出了越来越高的要求。
大光圈高像素的光学镜头的光学设计复杂，光学镜头的敏感度很高。随着目前镜头规格不断升高，从20M、40M、48M到64M乃至更高的像素数量，需要在体积较小的空间内设计更高像素的镜头，这样的镜头的光学敏感性非常高。因此，对光学镜头制造过程中产生的偏心和倾斜(tilt)要求都很严格。在常规的光学镜头组立过程中，任何 一片光学镜片出现倾斜或者偏心的现象，就会对光学镜头的整体光学性能造成较大影响。另外，随着光学镜头内镜片的数量不断增加，例如，由5个镜片向着6个镜片、7个镜片甚至更多个镜片增加，在满足越来越高的体积和性能要求的同时，光学镜头的组装难度在不断提升，导致在光学镜头的生产过程中，光学镜头的成品良率在不断下降。
分体式光学镜头的至少部分地解决了上述问题。在分体式光学镜头中，将一个完整的光学镜头分成多个子光学镜头，子光学镜头包括镜筒和组装在镜筒中的至少一个光学镜片。该至少一个光学镜片通常通过在非光学区与镜筒接触的位置布设一圈胶材来接合在镜筒中。
以下解释常规的分体式光学镜头的组装方法。在该组装方法中，首先，通过主动校准(AA，Active Alignment)的方式，调整分体式光学镜头的各个子光学镜头与感光组件之间的位置，直至满足成像要求；然后，通过胶材将各子镜头固定连接在主动校准所确定的相对位置。
为了使整个分体式光学镜头的结构更加稳固，相较于普通光学镜头，分体式镜头采用了更多的胶水来固定整个光学系统。虽然这样降低了组装难度，提高了产品的生产良率，但是，胶材本身与镜筒和镜片的材质在温度特性、机械特性等方面不一致。在后期的组装过程或可靠性试验过程中，子光学镜头中的胶材或连接固定各光学子镜头的胶材在由于烘烤或其他原因造成光学镜头所处环境温度变化时，会膨胀或收缩，从而造成不定向的变形，因而光学镜头的结构产生较大的变化。具体而言，子光学镜头中材的膨胀或收缩，该膨胀或收缩产生的力会导致子光学镜头中的光学镜片发生偏移或者倾斜，从而使得光学镜头的光学性能严重下降。
另外，如上所述，因为影响镜头解像力的因素非常多，存在于多个元件中，每个因素的控制都存在制造精度的极限，如果只是单纯提升各个元件的精度，提升能力有限，提升成本高昂，而且不能满足市场日益提高的成像品质需求。
近些年来，模组厂通过在将成像镜头和感光模组组装时，通过主动校准工艺对感光芯片的倾斜进行补偿。然而这种工艺补偿能力有限。 由于多种影响解像力的像差来源于光学系统本身的能力，当光学成像镜头本身的解像力不足时，现有的感光模组主动校准工艺是难以补偿的。

图1示出了现有技术中常规分体式光学镜头1000的示意性剖视图。如图1所示，该分体式镜头包括第一子镜头部件1100和第二子镜头部件1200。第一子镜头部件1100和第二子镜头部件1200分别包括一个镜筒(1110、1210)和至少一个镜片(1120、1220)。
在本领域的常规组装过程中，通过主动校准来确定第一子镜头部件1100和第二子镜头部件1200之间的相对位置，然后，通过诸如胶水的连接介质1300来连接第一子镜头部件1100和第二子镜头部件1200，从而固定第一子镜头部件1100和第二子镜头部件1200在主动校准期间所确定的位置。
在本文中，主动校准是指：将第一子镜头部件1100和第二子镜头部件1200分别置于感光芯片的感光路径上，并使第一子镜头部件1100和第二子镜头部件1200所组成的镜头能正常成像；感光组件通电开图，获取该分体式光学镜头1000所成的图像；根据所成图像的品质(通常依据TV line、MTF、SFR等方式判断)，在至少一个方向上调整第一子镜头部件1100相对于第二子镜头部件1200的相对位置，所述至少一个方向是指水平方向(xy)、竖直方向(z)、倾斜方向(vw)和圆周方向(u)中的至少一个，或者是xyz(水平及竖直方向)、uvw(分别是绕z、x、y)六轴方向上的至少一个；通过在第一子镜头部件1100和第二子镜头部件1200之间布设胶材并固化胶材来固定该相对位置。其中，布设胶材的步骤可以在主动校准步骤之前进行，即在调整相对位置之前进行，也可以在确定相对位置之后进行。
因此，对于分体式光学镜头1000来说，第一子镜头部件1100和第二子镜头部件1200之间必然存在间隙。在镜头部分设置胶材以固定连接第一子镜头部件1100和第二子镜头部件1200；第一子镜头部件1100和第二子镜头部件1200通过胶材来固定镜片(1120、1220)与镜筒(1110、1210)。
主要由于各子镜头部件之间粘接的胶材以及子镜头部件中用于固定所组立镜片的胶材，分体式光学镜头1000可靠性较差。
图2示出了根据本申请一个实施例的光学镜头2000的示意性剖视图。如图2所示，在该实施例中，该光学镜头2000的两个子镜头部件(2100、2300)处于组装状态。这两个子镜头部件(2100、2300)彼此接合，且均包括镜筒和镜片。
图3示出了根据本申请一个实施例的光学镜头的子镜头部件2100的示意性剖视图。在图2中仅示出作为示例的子镜头部件2100。
该光学镜头2000还可包括连接介质。该连接介质适于将该多个子镜头部件固定在一起。该光学镜头2000还包括卡扣机构。该多个子镜头部件2100中的至少一个的镜筒2110和镜片2120通过卡扣机构2200接合。
在该实施例中，子镜头部件2100的镜筒2110和镜片2120通过卡扣机构2200组装在一起，从而形成牢固的结构，以减少子镜头部件2100中胶材与镜片2120的接触面积。在这种情况下，胶材可完全取消，也可以涂少量胶材作为对子镜头部件2100结构的补强。胶材可为光固化、热固化、湿气固化、厌氧固化或氧化固化胶材。
如图3所示，该子镜头部件2100的镜筒2110和镜片2120处于未组装状态，并且镜筒2110沿其内侧周向设置有作为卡扣机构2200的凸起部2210和凹陷部2220。
图4示出了根据本申请一个实施例的光学镜头的子镜头部件3100的示意性立体图。
在该实施例中，该多个子镜头部件3100包括镜筒3110和镜片3120。
该光学镜头还包括连接介质。该连接介质适于将该多个子镜头部件固定在一起。该光学镜头还包括卡扣机构3200。该多个子镜头部件中的至少一个的镜筒和镜片通过卡扣机构3200接合。
在该实施例中，子镜头部件3100的镜筒3110和镜片3120通过卡扣机构3200组装在一起，从而形成牢固的结构，以减少子镜头部件3100中胶材与镜片3120的接触面积。在这种情况下，胶材可完全取消，也可以涂少量胶材作为对子镜头部件3100结构的补强。
如图4所示，该子镜头部件3100的镜筒3110和镜片3120处于未组装状态，并且镜筒3110沿其内侧周向均匀设置有作为卡扣机构3200的凸起部3210和凹陷部3220。换言之，卡扣机构3200可包括多个凸起部3210和凹陷部3220。在图4中所示的示例中，卡扣机构3200包括4个凸起部3210和相应的4个凹陷部3220。凸起部3210和凹陷部3220沿镜筒3110的内侧周向均匀设置是为了使镜片3120受到镜筒3110的力能够均匀。
图5示出了根据图3所示实施例的光学镜头的子镜头部件2100的示意性剖视图。在图5中，该子镜头部件2100的镜筒2110和镜片2120处于组装状态。
如图5所示，镜片2120的周向边缘接合在卡扣机构2200的凹陷部2220内，从而使镜片2120和镜筒2110牢固接合。
图6示出了根据本申请一个实施例的光学镜头的子镜头部件4100的示意性立体图。
在图6中，该子镜头部件4100的镜筒4110和镜片4120处于未组装状态。在该实施例中，镜筒4110沿其内侧周向设置有作为卡扣机构4200的环状凸起部4210和环状凹陷部4220。环状凸起部4210和环状凹陷部4220沿镜筒4110的整个周向内侧设置，换言之，卡扣机构4200仅包括一个环状凸起部4210和一个环状凹陷部4220。因而，镜片4120受到镜筒4110的力能够均匀。
图7示出了根据本申请一个实施例的光学镜头5000的示意性剖视图。
在该实施例中，该光学镜头5000包括两个子镜头部件-第一子镜 头部件5100和第二子镜头部件5200。第一子镜头部件5100和第二子镜头部件5200彼此接合，且均包括镜筒和镜片。
该光学镜头5000还包括连接介质5300。该连接介质5300适于将第一子镜头部件5100和第二子镜头部件5200固定在一起。该光学镜头5000还包括卡扣机构5400。第一子镜头部件5100的镜筒5110和镜片5120通过卡扣机构5400接合在一起，从而形成牢固的结构，以减少第一子镜头部件5100中胶材与镜片5120的接触面积。在这种情况下，第一子镜头部件5100中的胶材可完全取消，也可以涂少量胶材作为对第一子镜头部件5100结构的补强。
如图7所示，该第一子镜头部件5100的镜筒5110和镜片5120之间施加有少量作为连接介质的胶材，以进一步固定镜片5120在镜筒5110中的位置。
在各个实施中，子镜头部件的镜片与镜筒之间均可施加胶材，从而辅助固定镜片与镜筒。
图8a示出了图1中所示的光学镜头的第一子镜头部件1100的镜筒1110和镜片1120经常规连接后的示意性剖视图。
在组装分体式光学镜头时，胶材通常设置在位于下方的子镜头部件的镜筒上。下子镜头部件通常具有较大的施胶面积，但上子镜头部件可用于粘接的面积相对较小。
如图8a所示，镜筒1110和镜片1120之间通过作为连接介质的胶材1130来连接，且镜筒1110的用于与其他子镜头部件的镜筒连接的下连接面1111的面积较小。
图8b示出了根据图3所示实施例的光学镜头的子镜头部件2100的示意性剖视图。在图8b中，该子镜头部件2100的镜筒2110和镜片2120处于组装状态。
如图8b所示，镜片2120的周向边缘接合在卡扣机构2200的凹陷部2220内，从而使镜片2120和镜筒2110牢固接合。另外，与图8a所示的第一子镜头部件1100相比，镜筒2110的用于与其他子镜头部 件的镜筒连接的连接面2111的面积较大。
因此，在第一子镜头部件的横向尺寸(xy方向)一定的情况下，子镜头部件2100具有相对较大的粘接面积，以使得个子镜头部件之间的粘接力更大，使分体式镜头的可靠性更好，并且由于具有较大的粘接面积，使得胶水的布设方式可以更加的多样化。同样，在粘接面积一定的情况下，第一子镜头部件的横向尺寸可设置为更小，从而进一步减小整个光学镜头的体积。
图9示出了根据本申请一个实施例的光学镜头的子镜头部件6100的示意性立体图。在图9中，该子镜头部件6100的镜筒6110和镜片6120处于未组装状态。镜筒6110沿其内侧周向均匀设置有卡扣机构6200的凹陷部6210，以及镜片6120具有沿其外侧周向均匀设置的卡扣机构6200的凸起部6220。凹陷部6210包括第一凹陷部分6211和第二凹陷部分6212。
在组装该子镜头部件6100时，镜片6120的凸起部6220通过第一凹陷部分6211进入第二凹陷部分6212，并通过旋转镜片6120，从而以卡扣方式固定在镜筒6110的第二凹陷部分6212中。
可选择地，可在凸起部6220与凹陷部6210的结合处施加胶材，以补强作用。可设想到的是，卡扣机构6200也可设置为包括沿镜筒6110的内侧周向均匀设置的凸起部和沿镜片6120的外侧周向均匀设置的凹陷部。
图10示出了根据本申请一个实施例的光学镜头(未示出)的子镜头部件7100的镜筒7110和镜片7120的卡扣式连接的示意性剖视图。该子镜头部件7100的镜筒7110和镜片7120处于未组装状态。
如图10所示，镜筒7110和镜片7120之间通过卡扣机构7200来连接。该卡扣结构7200包括位于镜筒7110的内侧周向均匀设置的凸起部7220和位于镜片7120的外侧周向均匀设置的凹陷部7210。
图11示出了图10中所示的光学镜头的子镜头部件7100的镜筒7110和镜片7120的卡扣式连接的示意性剖视图。在图11中，该子镜 头部件7100的镜筒7110和镜片7120处于组装状态。
图12示出了根据本申请一个实施例的光学镜头(未示出)的子镜头部件8100的镜筒8110和镜片8120的卡扣式连接的示意性剖视图。
该实施例与图10和图11中所示的实施例相似，其不同之处在于，卡扣结构8200包括位于镜筒8110的内侧周向均匀设置的凹陷部8220和位于镜片8120的外侧周向均匀设置的凸起部8210。
图13示出了根据本申请一个实施例的光学镜头(未示出)的子镜头部件9100的示意性分解立体图。
如图13所示，卡扣机构9200包括在镜筒9110的内侧部形成的凸起部9210和遮光部9220。镜筒9110在上端部开放以接收镜片9120和遮光部9220。
图14示出了图13中所示的光学镜头的子镜头部件9100的示意性剖视图，其中，该子镜头部件9100的镜筒9110和镜片9120处于组装状态。
如图14所示，镜片9120的边缘与镜筒9110的内侧部和凸起部9210配合。遮光部9220位于镜片9120的上方，并且与镜筒9110的内侧部接合。在遮光部9220与镜筒9110的内侧部之间施加胶材，以固定遮光件。
遮光部9220可由任意适合材料制成，诸如塑料、金属、黑膜。
遮光部部9220也可以是胶材，例如不透光的胶材。例如，如图15所示，在镜筒9110的内侧部形成凸起部9210和由例如不透光胶材的连接介质形成的遮光部9220。
图16示出了根据本申请一个实施例的摄像模组100的示意性剖视图。
如图16所示，在该示例中，摄像模组100包括两个子镜头部件-第一子镜头部件和第二子镜头部件120。其中，第一子镜头部件为图3中示出的子镜头部件2100类似，出于清晰的目的，在以下描述中使用 与图3中相同的附图标记。虽然在该实施例中采用了图3中示出的子镜头部件2100，但应理解的是，摄像模组100可包括上述具有卡扣结构的子镜头部件的实施例中的任意一个。
第一子镜头部件2100和第二子镜头部件120彼此接合，且均包括镜筒和镜片。
该摄像模组100还包括摄像模组中常见的其他部件，出于清晰的目的，对这些本领域众所周知的部件不再进行详细描述。
光学镜头100包括连接介质130。该连接介质130将第一子镜头部件2100和第二子镜头部件120固定在一起。
在上文所述的实施方式中，具有卡扣结构的子镜头部件比没有卡扣结构的子镜头部件更靠近物侧。另外，具有卡扣结构的子镜头部件也可更靠近像侧。
