近些年，随着半导体工艺的发展，影像传感器的像素越来越高，与影像传感器配合的光学镜头的解像度也越来越高。然而，为了达到高像素，光学镜头包含的镜片的数量越来越多，镜片数量的增加容易影响光学镜头组装的成功率。现有技术中在组装光学镜头时需将所有的镜片依次安装于同一个镜筒内，这样在组装结束后镜片的排列情况将无法调整，使得组装后的光学镜头中存在很多解析力不良品。

第一方面，参见图5，本申请实施例提供了一种镜头组件100，包括第一镜头110和第二镜头120，第二镜头120位于第一镜头110的像侧。为提升镜头组件100的解析力，镜头组件100还可以包括第三镜头、第四镜头等，相邻的两个镜头之间的组装方式相似，因此，本申请实施例中仅以镜头组件100包括第一镜头110和第二镜头120为例进行详细说明。
参见图1和图2，第一镜头110可以包括第一镜筒111及位于第一镜筒111内的第一镜片组112。第一镜片组112包括至少一个第一镜片，所有的第一镜片均安装于第一镜筒111内，且所有的第一镜片均沿第一光轴m顺序排列。为便于第一镜筒111内成型用于安装第 一镜片的第一安装槽以及确保每个第一镜片在对应的第一安装槽内的平稳固定，第一光轴m可以与第一镜筒111的中轴线共线。
第一镜片组112的最大外径尺寸可以为1mm至8mm。具体地，第一镜片组112的最大外径尺寸可以为3mm、5mm、7mm等。为使第一镜片组112在第一镜筒111内的平稳固定，第一镜筒111的最大外径尺寸可以为第一镜片组112的最大外径尺寸的1.05倍至1.8倍。具体地，第一镜筒111的最大外径尺寸可以为第一镜片组112的最大外径尺寸的1.2倍、1.4倍或1.6倍。第一镜筒111沿平行于第一光轴m方向的最大高度尺寸可以为0.5mm至5mm。具体地，第一镜筒111沿平行于第一光轴m方向的最大高度尺寸可以为1mm、2mm、3mm、4mm等。
参见图3和图4，第二镜头120可以包括第二镜筒121及位于第二镜筒121内的第二镜片组122。第二镜片组122包括至少一个第二镜片，所有的第二镜片均安装于第二镜筒121内，且所有的第二镜片均沿第二光轴n顺序排列。为便于第二镜筒121内成型用于安装第二镜片的第二安装槽以及确保每个第二镜片在对应的第二安装槽内的平稳固定，第二光轴n可以与第二镜筒121的中轴线共线。
参见图4，第二镜筒121包括面向第一镜筒111的壁板1212，第二镜片组122的物侧面为第二表面1221，为使第二镜片组122在第二镜筒121内的平稳固定，第二镜片组122在安装于第二镜筒121内时，第二表面1221将抵接于壁板1212。为确保壁板1212能够固定第二镜片组122，壁板1212沿平行于第一光轴m方向的高度尺寸可以为0.18mm至0.6mm。具体地，壁板1212沿平行于第一光轴m方向的高度尺寸可以为0.2mm、0.3mm、0.4mm、0.5mm等。
参见图1至图4，第一镜片组112的像侧面为第一表面1121。第一表面1121可以位于所有的第一镜片中，最靠近第二镜片组122的一个第一镜片上。具体地，第一表面1121可以为该第一镜片的像侧面。第二镜片组122的物侧面为第二表面1221。第二表面1221可以位于所有的第二镜片中，最靠近第一镜片组112的一个第二镜片上。具体地，第二表面1221可以为该第二镜片的物侧面。第一镜筒111的像侧面为第三表面1111。第二镜筒121的物侧面为第四表面1211。第四表面1211可以为壁板1212的物侧面。第三表面1111和第四表面1211均为环形面。
第一表面1121设置有第一连接部，第二表面1221设置有第二连接部，第一连接部与第二连接部可调整连接。为使第一连接部与第二连接部连接后，第一镜头110相对于第二镜头120沿垂直于第二光轴n方向的运动行程足够大且第一镜头110相对于第二镜头120能够在垂直于第二光轴n的方向顺利移动，第三表面1111在经过第二光轴n的参考面123上的正投影为第一投影11111，第四表面1211在经过参考面123上的正投影为第二投影12111，第一投影11111与第二投影12111不重合，可参见图8。第一投影11111和第二投影12111不重合可以为第一投影11111和第二投影12111相互隔开，也可以为第一投影11111的部分边界线与第二投影12111的部分边界线重合。通过将第一投影11111限定为与第二投影12111不重合，能够使第一镜筒111相对于第二镜筒121沿垂直于第二光轴n的方向运动时，第三表面1111和第四表面1211不会造成阻碍。
参考面123可以为第二光轴n所处的任意表面。第三表面1111可以为圆心位于第一光轴m上的环形面，第四表面1211可以为圆心位于第二光轴n上的环形面，当第一镜头110与第二镜头120经第一连接部与第二连接部连接预定位后，第一镜头110的第一光轴m与第二镜头120的第二光轴n就接近重合，参见图5，因参考面123为第二光轴n所处的表面，因此参考面123会将第三表面1111拆分为几乎完全相同的两部分，将第四表面1211拆分为完全相同的两部分，第一投影111111可以看作为第三表面1111的一半在参考面123上的正投影，第二投影12111为第四表面1211的一半在参考面123上的正投影。
第三表面1111可以为任意的形状。如，第三表面1111可以为平面，也可以为非平面。当第三表面1111为平面时，第三表面1111可以与第二光轴n垂直，也可以不与第二光轴n垂直。第一投影11111可以为一条线段也可以为具有一定面积的一块区域。如，当第三表面1111为平面且与第二光轴n垂直时，第一投影11111为一条线段。当第三表面1111为平面且不与第二光轴n垂直时，第一投影11111为具有一定面积的一块区域。当第三表面1111为非平面时，第一投影11111为具有一定面积的一块区域。
第四表面1211可以为任意的形状。如，第四表面1211可以为平面，也可以为非平面。当第四表面1211为平面时，第四表面1211可以与第二光轴n垂直，也可以不与第二光轴n垂直。第二投影12111可以为一条线段也可以为具有一定面积的一块区域。如，当第四表面1211为平面且与第二光轴n垂直时，第二投影12111为一条线段。当第四表面1211为 平面且不与第二光轴n垂直时，第二投影12111为具有一定面积的一块区域。当第四表面1211为非平面时，第二投影12111为具有一定面积的一块区域。
第二连接部和第一连接部可调整连接可以为第一连接部设置于第二连接部内，也可以为第二连接部设置于第一连接部内。以下以第一连接部设置于第二连接部内为例进行详细的说明：
为保证第一连接部与第二连接部的可靠连接，第一连接部沿平行于第一光轴m方向的高度尺寸可以为0.1mm至0.5mm。具体地，第一连接部沿平行于第一光轴m方向的高度尺寸可以为0.2mm、0.3mm、0.4mm等。为使第一连接部与第二连接部的可靠连接，第一连接部的像侧面可以抵接于第二连接部的物侧面。
第一连接部可以为第一表面1121的中部设置的凸起，第二连接部可以为第二表面1221的中部设置的凹槽。为使凸起与凹槽连接后，第一镜头110相对于第二镜头120能够顺利的转动，凸起的外周面可以为圆柱状的面，也可以为从第一表面1121至第二表面1221的方向上，半径逐渐减小的圆台状的面。当凸起的外周面为圆柱状的面时，凹槽的内周面可以为与凸起的外周面相匹配的圆柱状的面。当凸起的外周面为圆台状的面时，凹槽的内周面可以为与凸起的外周面相匹配的圆台状的面。为使凸起嵌设于凹槽内后，在第一镜头110相对于第二镜头120转动的过程中，即凸起相对于凹槽转动的过程中，第一光轴m与第二光轴n的间距不会出现较大的变动，凸起的中轴线可以与第一光轴m共线，凹槽的中轴线可以与第二光轴n共线。
参见图1至图6，为使经第一连接部和第二连接部连接后，第一镜头110与第二镜头120的预定位较为可靠，第一连接部可以为第一表面1121上设置的横截面为环形的凸缘11211，第二连接部可以为第二表面1221上设置的环形槽12211，凸缘11211设置于环形槽12211内。凸缘11211为在垂直于第一光轴m方向的所有截面均为环形的部件。为使凸缘11211设置于环形槽12211内后，在第一镜头110相对于第二镜头120转动的过程中，即凸缘11211相对于环形槽12211转动的过程中，第一光轴m与第二光轴n的间距不会出现较大的变动，凸缘11211的中轴线可以与第一光轴m共线，环形槽12211的中轴线可以与第二光轴n共线。凸缘11211具有背离第一表面1121的第一圆环面11211a、绕第一圆环面11211a的内圈设置的第一内周面11211b及绕第一圆环面11211a的外圈设置的第一外周面。 环形槽12211具有面向第一表面1121的第二圆环面12211a、绕第二圆环面12211a的内圈设置的第二内周面12211b及绕第二圆环面12211a的外圈设置的第二外周面。第一圆环面11211a可以抵接于第二圆环面12211a。
参见图6，为使凸缘11211与环形槽12211连接后，第一镜头110相对于第二镜头120能够顺利的转动，凸缘11211的第一内周面11211b可以为圆柱状的面，也可以为从第一表面1121至第二表面1221的方向上，半径逐渐增大的圆台状的面。当凸缘11211的第一内周面11211b为圆台状的面时，环形槽12211的第二内周面12211b可以为从第一表面1121至第二表面1221的方向上，半径逐渐增大的圆台状的面，第一内周面11211b位于第二内周面12211b的外周，为便于凸缘11211与环形槽12211的拆装，第一内周面11211b的母线与第一光轴m的夹角θ1可以与第二内周面12211b的母线与第二光轴n的夹角相等。第一内周面11211b的母线与第一光轴m的夹角θ1可以为0°至60°。通过将第一内周面11211b的母线与第一光轴m的夹角θ1限定为0°至60°，能够避免夹角过大，即第一内周面11211b过于倾斜，造成凸缘11211从环形槽12211内脱离，能够保证凸缘11211与环形槽12211连接的可靠性。
第二内周面12211b可以全部位于第一内周面11211b内，也可以部分位于第一内周面11211b内。将第二内周面12211b的位于第一内周面11211b内的部分定义为连接段，参见图6，为进一步的保证凸缘11211与环形槽12211连接的可靠性，连接段沿第二内周面12211b的母线方向的长度尺寸h5可以为0.03mm至0.2mm。具体地，连接段沿第二内周面12211b的母线方向的长度尺寸h5可以为0.07mm、0.1mm等。
参见图6，凸缘11211沿垂直于第一光轴m方向的厚度尺寸为第一尺寸h1，环形槽12211沿垂直于第二光轴n方向的宽度尺寸为第二尺寸h2，第二尺寸h2大于第一尺寸h1。通过将第二尺寸h2限定为大于第一尺寸h1，能够保证第一镜头110与第二镜头120通过凸缘11211与环形槽12211连接后，凸缘11211在环形槽12211内可以具有沿垂直于第二光轴n方向的运动行程，以实现第一镜头110相对于第二镜头120的偏心校准。第二尺寸h2可以比第一尺寸h1大0.05mm至0.5mm。通过将第二尺寸h2限定为比第一尺寸h1大0.05mm至0.5mm，能够保证在第一镜头110相对于第二镜头120具有偏心校准的运动行程的前提下，实现镜头组件100的小型化。具体地，第二尺寸h2可以比第一尺寸h1大0.1mm、0.2mm、 0.3mm、0.4mm等。
环形槽12211可以为第二表面1221直接向内凹陷形成。当然，参见图3和图4，为降低第二镜片组122的成型难度，第二表面1221的边缘区域可以凹陷形成台阶12212，台阶12212具有面向第一表面1121的台阶面12212a，且台阶面12212a位于第四表面1211的像侧，以使第二表面1221、台阶面12212a和第四表面1211之间围合形成环形槽12211。这样仅通过在第二镜片组122的第二表面1221形成台阶12212，且使台阶12212的台阶面12212a位于第四表面1211的像侧，即可在第二镜头120上形成环形槽12211，从而实现凸缘11211与环形槽12211的连接，使得第二镜头120的加工工艺简单，制造成本降低。台阶面12212a抵接于壁板1212的像侧面。
第二表面1221的边缘区域可以为从第二表面1221的第三外边界线向内延伸第三预定距离的部分。第三预定距离可以为0.6mm至1.2mm；具体地，可以为0.8mm、1.0mm等。
参见图6，第三表面1111和第四表面1211可以为任意结构，只需保证第一投影11111与第二投影12111不重合即可。当然，为使镜头组件100的结构整齐，第三表面1111可以与第四表面1211平行。第三表面1111至第四表面1211的距离为第三尺寸h3，第三尺寸h3可以为0mm至0.3mm。通过将第三表面1111至第四表面1211的距离限定为0mm至0.3mm，能够在保证第一镜头110相对于第二镜头120能够顺利转动的前提下实现镜头组件100的小型化。具体地，第三尺寸h3可以为0.1mm、0.2mm等。当然，将整个第三表面1111设置为与整个第四表面1211平行，则成型难度较大，为降低第三表面1111和第四表面1211的成型难度，可以仅将第三表面1111的边缘区域设置为与第四表面1211的边缘区域平行。而第三表面1111的边缘区域以外的部分只需保证与第四表面1211的边缘区域以外的部分相隔开即可。
第三表面1111的边缘区域可以为从第三表面1111的第二外边界线向内延伸第一预定距离的部分。第四表面1211的边缘区域可以为从第四表面1211的第一外边界线12112向内延伸第二预定距离的部分。第一预定距离可以为0.6mm至1.2mm；具体地，可以为0.8mm、1.0mm等。第二预定距离可以为0.1mm至0.5mm；具体地，可以为0.2mm、0.3mm、0.4mm等。
参见图1、图2和图7，第一镜筒111具有绕第三表面1111设置的第三外周面1112， 第三外周面1112与第三表面1111的交界线在第四表面1211上的正投影为第三投影1113，第三投影1113可以位于第四表面1211内。通过将第三外周面1112与第三表面1111的交界线在第四表面1211上的正投影限定为位于第四表面1211内，使第四表面1211具有位于其第一外边界线12112与第三投影1113之间的预留区域，当第一镜头110与第二镜头120调整到位后可通过在该预留区域采用胶水使第一镜头110与第二镜头120连接在一起，保证第一镜头110与第二镜头120之间的有效连接。
参见图6，为便于第一镜头110和第二镜头120调整到位后的安装固定，第三外周面1112与第四表面1211的夹角θ2可以为10°至80°。通过将第三外周面1112与第四表面1211的夹角θ2限定为10°至80°，既可以避免第三外周面1112与第四表面1211的夹角θ2过小，使在第三外周面1112与第四表面1211之间采用胶水连接时，胶水能够容易的进入到第三外周面1112与第四表面1211之间，连接更加方便；又可以避免第三外周面1112与第四表面1211的夹角θ2过大，使在第三外周面1112与第四表面1211之间采用胶水连接时，仅需要适量的胶水就能够将第三外周面1112与第四表面1211紧固连接，减少胶水的投入成本。具体地，第三外周面1112与第四表面1211的夹角θ2可以为15°、30°、45°、60°、75°等。
参见图6和图7，为使第四表面1211的位于第三投影1113与第一外边界线12112之间的预留区域分布均匀，在垂直于第二光轴n的直线方向上，第三投影1113至第一外边界线12112的距离可以处处相等。通过上述限定，能够使第四表面1211的位于第三投影1113与第一外边界线12112之间的预留区域分布均匀，使在该预留区域采用胶水使第一镜头110与第二镜头120连接时，该预留区域的各个部位的连接均较为可靠。在垂直于第二光轴n的直线方向上，第三投影1113至第一外边界线12112的距离为第四尺寸h4，第四尺寸h4可以为0.1mm至0.6mm。通过将第三投影1113至第一外边界线12112的距离限定为0.1mm至0.6mm，既能够保证镜头组件100的小型化又能够保证第一镜头110与第二镜头120之间连接的稳固性。具体地，第四尺寸h4可以为0.2mm、0.3mm、0.4mm、0.5mm等。
