背景技术
随着摄像技术的发展，市场对摄像镜头的成像质量的要求也越来越高，摄像镜头中通常包括多片透镜，在摄像镜头的组装过程中，需要将多个透镜组装于镜筒中，多片透镜以及镜筒之间的组装精度极大影响着摄像镜头的成像质量。然而，目前的透镜组装过程中，当相互抵接的两个透镜之间孔径差距较大，导致两个透镜之间未承靠部分的段差尺寸较大时，组装过程中容易发生透镜变形的情况，降低透镜与镜筒之间组装精度低，难以满足摄像镜头高成像质量的要求。

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较佳实施方式。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方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
请参见图1和图2，图1示出了一些实施例中镜头组件100的剖面示意图，图2示出了另一些实施例中镜头组件100的剖面示意图。镜头组件100包括镜筒110以及安装于镜筒110内的第一透镜120、第二透镜130及第三透镜140。镜筒110可以为镜筒或其他用于固定透镜的固定结构。第二透镜130、第一透镜120及第三透镜140依次层叠设置于镜筒110形成的容纳空间150内，且镜筒110具有一供第一透镜120、第二透镜130及第三透镜140进入容纳空间150内的开口160。第二透镜130设置于第一透镜120背离开口160的一侧并抵接镜筒110及第一透镜120，第三透镜140设置于第一透镜120朝向开口160的一侧。
需要说明的是，第二透镜130可以为由多片透镜组成的透镜组，第三透镜140可以为镜头组件100中最靠近开口160的透镜，第三透镜140可以直接与第一透镜120抵接，第一透镜120与第三透镜140之间也可以存在其他透镜，例如，在图1所示的实施例中，第一透镜120与第三透镜140之间还设置有一个透镜。第三透镜140朝向开口160的一侧通过粘连胶170与镜筒110连接，以将第一透镜120与第二透镜130固定于容纳空间150内。
第一透镜120包括透光部121及环绕透光部121边缘的承靠部122，透光部121可以为第一透镜120的光学有效径部分，承靠部122可以为第一透镜120边缘与其他结构承靠或连接的结构，透光部121与承靠部122可以通过注塑成型工艺一体成型。镜筒110通常形成有台阶部111，台阶部111环绕镜筒110的轴线设置，以供承靠部122承靠，台阶部111包括相互连接的承载壁112以及侧壁113。当第一透镜120安装于镜筒110时，承靠部122至少部分结构位于侧壁113和承载壁112围合形成的空间内，例如，承载壁112与承靠部122相对，侧壁113环绕承靠部122的外周。
可以理解的是，第二透镜130两侧分别抵接镜筒110及第一透镜120，当镜头组件100的加工存在误差时，容易导致承靠部122与承载壁112之间产生间隙，进而导致第一透镜120因压力、温度、湿度变化等因素而松动或变形，影响 镜头组件100的组装精度，难以满足镜头组件100高成像质量的要求。
为提升镜头组件100的组装精度，在一些实施例中，台阶部111开设有至少两个贯穿台阶部111的调节孔114，调节孔114沿台阶部111的周向间隔设置。镜头组件100还包括填充件180，填充件180从调节孔114进入并填充承靠部122与承载壁112之间的间隙，以支撑第一透镜120。填充件180的支撑作用，能够限缩第一透镜120在镜筒110内的移动空间，避免第一透镜120因承靠部122与承载壁112之间的间隙而松动或变形的情况，以此提升镜头组件100的组装精度。进一步地，填充件180可以粘连承载壁112以及承靠部122，使得填充件180与镜筒110及第一透镜120之间的结合更加稳定。当然，填充件180还可填充调节孔114，以增大填充件180与镜筒110的粘连面积，提升填充件180与镜筒110的结合强度，使得填充件180能够对第一透镜120提供更稳定的支撑作用。
调节孔114的设置方式不限，只要填充件180能够从调节孔114进入承载壁112及承靠部122之间的间隙即可。在一些实施例中，调节孔114贯穿承载壁112，且调节孔114的轴向平行于镜头组件100的轴线。在另一些实施例中，调节孔114贯穿侧壁113，调节孔114的轴向垂直于镜头组件100的轴线。需要说明的是，当镜头组件100中各透镜各轴以形成光学系统的光轴时，镜头组件100的轴线可以理解为镜头组件100中各透镜组成的光学系统的光轴。具体地，在一些实施例中，承载壁112垂直于光轴，侧壁113平行于光轴。例如，在图1所示的实施例中，调节孔114贯穿承载壁112，且调节孔114的轴向可垂直于承载壁112，以便于填充件180能够不受阻碍地从调节孔114进入承靠部122与承载壁112之间的间隙。在图2所示的实施例中，调节孔114贯穿侧壁113，则调节孔114的轴向可垂直于侧壁113，有利于填充件180进入承靠部122与承载壁112之间。可以理解的是，当调节孔114贯穿侧壁113时，调节孔114的孔径可大于承靠部122与承载壁112之间的最短距离，以便于填充件180从调节孔114进入。当然，在另一些实施例中，承载壁112与侧壁113也可倾斜于光轴。
进一步地，调节孔114的数量及分布不限，参考图3和图4所示，在一些实施例中，调节孔114设置有四个，调节孔114沿台阶部111的周向均匀分布。例如，在图3所示的实施例中，承载壁112的形状大致呈环形，调节孔114贯穿承载壁112，且任意相邻两个调节孔114于承载壁112的周向上的距离相等。在图4所示的实施例中，调节孔114贯穿侧壁113，且任意相邻两个调节孔114在台阶部111的周向上的距离相等。调节孔114沿台阶部111的周向均匀分布，使得填充件180能够沿调节孔114从不同位置进入承靠部122与承载壁112之间，对第一透镜120周向上的各个部分起支撑作用，从而使得第一透镜120的受力均匀，提升第一透镜120的稳定性，进一步提升镜头组件100的组装精度。当然，调节孔114还可以设置为三个、五个、六个等。
一并结合图1和图5所示，上述镜头组件100可与壳体210组装形成电子设备200，镜头组件100安装于壳体210内。具体地，电子设备200包括但不限于为：摄像机、智能手机、平板电脑、车载记录仪、电子阅读器等配置有透镜的设备。在电子设备200中采用上述镜头组件100，镜头组件100的组装精度高，能够满足电子设备200高成像质量的要求。
请参见图6和图7，图6示出了一些实施例中组装设备300的示意图，图7示出了另一些实施例中组装设备300的示意图。组装设备300可用于对上述任一实施例所述的镜头组件100进行组装，采用组装设备300对镜头组件100进行组装的方法将在后续进行详细说明。
在一些实施例中，组装设备300包括限位件310以及至少两个支撑件320。限位件310用于固定镜头组件100，具体地，限位件310包括底板311和侧板312，侧板312环绕底板311的边缘并与底板311围设形成用于收容镜头组件100的收容腔313。底板311或者侧板312上形成有至少两个相互间隔的限位孔314，限位孔314与调节孔114一一对应，在组装时，每个限位孔314与对应的一个调节孔114相对。支撑件320的材质包括但不限于为金属、塑料、玻璃等。支撑件320与限位孔314一一对应，每个支撑件320的径向固定于对应的一个限位孔314中，且支撑件320能够沿限位孔314的轴向朝向靠近或远离镜头组件100的方向移动。
上述组装设备300，在镜头组件100的组装过程中，支撑件320能够从调节孔114伸入承靠部122与承载壁112之间的间隙，并支撑第一透镜120，从而使得承靠部122与承载壁112彼此位置固定，而不易松动，有效防止了承靠部122与承载壁112之间的间隙导致第一透镜120受到组装压力时承靠部122相对透光部121发生变形的情况，有利于提升镜头组件100的组装精度，以满足高成像质量的要求。
可以理解的是，当镜头组件100固定于收容腔313内时，镜筒110的开口160背离底板311，则根据镜头组件100的调节孔114的不同设计，限位孔314也可以有不同的设置。例如，在图6所示的实施例中，调节孔114贯穿承载壁112，则限位孔314贯穿底板311，且限位孔314沿底板311的轴向间隔设置。进一步地，在一些实施例中，限位孔314的轴向垂直于底板311，且限位孔314与调节孔114同轴设置，以便于支撑件320进入调节孔114中。而在图7所示的实施例中，调节孔114贯穿侧壁113，则限位孔314贯穿侧板312，且限位孔314沿底板311的轴向间隔设置。当然，限位孔314的轴向也可垂直于侧板312，并与调节孔114同轴设置。
进一步地，一并参考图8、图9和图10所示，支撑件320与限位孔314的配合方式不限，只要支撑件320能够沿限位孔314的轴向朝靠近或远离镜头组件100的方向运动即可，具体地，支撑件320与限位孔314的配合方式包括但 不限于为：螺纹配合、丝杠配合、滚珠套筒配合、滚珠丝杠配合等。例如，在图8所示的实施例中，支撑件320与限位孔314采用螺纹配合，支撑件320的外周面与限位孔314的内壁面螺纹配合，则支撑件320可以为螺杆或丝杠，限位孔314可以为螺纹孔，且当支撑件320相对限位件310旋转时，支撑件320能够沿限位孔314的轴向移动。在图9所示的实施例中，支撑件320与限位孔314采用滚珠套筒配合，限位件310还包括滚珠套筒，滚珠套筒嵌入底板311或者侧板312内以形成限位孔314，换言之，限位孔314的内壁面设置有滚珠，支撑件320的外周面与滚珠套筒的滚珠配合。在图10所示的实施例中，支撑件320与限位孔314采用滚珠丝杠配合，支撑件320的外周面设置有螺纹，限位孔314的内壁面设置有滚珠，支撑件320的螺纹与内壁面的滚珠配合。
请参见图6和图11，图11示出了一些实施例中镜头组件100的组装方法，采用上述任一实施例所述的组装设备300对上述任一实施例所述的镜头组件100进行组装，组装方法包括如下步骤：
S110、一并结合图6和图7所示，提供组装设备300，将镜头组件100固定于收容腔313内，并使得调节孔114与限位孔314一一相对。具体地，镜头组件100固定于收容腔313内时，侧板312环绕镜筒110的外周并抵接镜筒110，底板311也抵接镜筒110，以将镜头组件100稳定固定。且当调节孔114与限位孔314一一相对时，支撑件320、调节孔114及限位孔314三者同轴设置。
S120、使支撑件320沿限位孔314的轴向朝向靠近镜头组件100的方向移动，并使得支撑件320从调节孔114进入承载壁112及承靠部122之间的间隙，调节支撑件320位于承载壁112及承靠部122之间的部分的尺寸，以使支撑件320支撑第一透镜120。
可以理解的是，支撑件320进入承载壁112及承靠部122之间时，既要使得支撑件320能够对第一透镜120起支撑作用，也要确保支撑件320位于承载壁112及承靠部122之间的部分的尺寸不能大于承载壁112与承靠部122之间的距离，避免支撑件320将第一透镜120顶出而改变镜片组件的组装位置。具体地，在图6所示的实施例中，支撑件320从承载壁112凸出，仅需使得支撑件320沿限位孔314的轴向移动，即可调节支撑件320位于承载壁112及承靠部122之间的部分的长度，以更好地支撑第一透镜120。而在图7所示的实施例中，支撑件320从垂直于侧壁113的方向进入承靠部122与承载壁112之间，若支撑件320的形状为柱状，难以调节支撑件320位于承载壁112的部分的径向尺寸，难以适配承靠部122与承载壁112之间的不同距离，从而容易影响第一透镜120的组装位置。
为使得支撑件320能够适配承靠部122与承载壁112之间的不同距离，一并参考图7、图12和图13所示，在一些实施例中，支撑件320包括本体部321以及凸轮部322，本体部321的径向固定于限位件310，凸轮部322固定于本体 部321朝向镜头组件100的一端的端面上，且在平行于端面的不同方向上，凸轮部322的径向尺寸不同。由此，当本体部321相对侧板312旋转时，能够改变凸轮部322在垂直于承载壁112的方向上的径向尺寸。当承靠部122与承载壁112之间的距离不同时，通过旋转本体部321，使得凸轮部322在光轴方向上的径向尺寸与承靠部122及承载壁112之间的距离相同，以使得凸轮部322能够在不影响第一透镜120的组装位置的同时对第一透镜120起支撑作用。
一并参考图7、图14和图15所示，在另一些实施例中，凸轮部322的横截面形状大致呈圆形，且凸轮部322的几何中心偏离本体部321的轴线。由此，当本体部321相对侧板312旋转时，能够改变凸轮部322在光轴方向上的位置，同样能够使得凸轮部322适配在光轴方向上承靠部122与承载壁112之间的不同距离，在不影响第一透镜120的支撑作用的前提下对第一透镜120起支撑作用。当然，凸轮部322还可以有其他的形状及设置方式，只要能够改变凸轮部322在光轴方向上的位置或径向尺寸，以适配承靠部122及承载壁112之间于光轴方向上不同距离即可。
S130、于第一透镜120背离承载壁112一侧施加组装压力。
具体地，参考图6所示，组装设备300还包括组装压头330，组装压头330在第三透镜140背离第一透镜120的一侧对第三透镜140的边缘施加压力，以使得镜头组件100内各透镜的组装更加紧密。可以理解的是，支撑件320支撑第一透镜120的承靠部122，在步骤S130中，第一透镜120的承靠部122不容易因承载壁112与承靠部122之间的间隙而相对透光部121变形，换言之，承靠部122不容易在组装压力的作用下相对透光部121朝向承载壁112弯折，能够提升镜头组件100的组装精度。
进一步地，参考图6所示，在一些实施例中，组装设备300还包括固定组件340，固定组件340包括固定座341及限位顶丝343，固定座341固定于限位件310背离收容腔313的一侧，例如镜筒110通过螺钉与限位件310固定。固定座341开设有顶丝孔342，顶丝孔342与限位孔314相对。限位顶丝343至少部分位于顶丝孔342内，且限位顶丝343能够沿顶丝孔342的轴向移动，例如，限位顶丝343与顶丝孔342螺纹连接。
则在步骤S120后，组装方法还包括，使得限位顶丝343沿顶丝孔342的轴向移动并抵接支撑件320。由此，在步骤S130中，当组装压头330对第三透镜140施加组装压力时，支撑件320不会因组装压力的作用而偏离，能够提升保证镜头组件100的组装精度。可以理解的是，在图6的实施例中，仅示出了其中一个固定组件340，而实际上，固定组件340可设置有至少两个，固定组件340与支撑件320一一对应，每个固定组件340用于在步骤S130中支撑对应的一个支撑件320。
当然，在另一些实施例中，限位顶丝343的端部还可与支撑件320通过磁 吸或胶粘等方式固定。则当限位顶丝343朝远离镜筒110的方向运动时，还能够带动支撑件320朝向远离镜筒110的方向运动，以调节支撑件320位于镜筒110内的部分的尺寸或使得支撑件320脱离镜筒110。
S140、移除支撑件320。可以使支撑件320沿限位件310的轴向朝远离镜头组件100的方向移动，使支撑件320脱离镜头组件100，也可以在支撑件320脱离镜头组件100后将镜头组件100与限位件310分离，只要不影响后续步骤的进行即可。
S150、提供填充件180填充所述承靠部122与所述承载壁112之间的间隙。
具体地，填充件180可以由热固胶经加热固化后形成，则步骤S150可以包括：
将热固胶从调节孔114注入承靠部122与承载壁112之间，直至热固胶填充承靠部122与承载壁112之间的间隙；
对热固胶进行加热固化，使其固化形成填充件180。
采用热固胶形成填充件180，在加热固化前具有流动性，能够有效地填充满承靠部122与承载壁112之间的间隙，且加热固化后具有足够的结构强度，能够在组装完成后对第一透镜120提供稳定有效的支撑作用，防止第一透镜120松动或变形。当然，在另一些实施例中，填充件180还可由紫外光固化胶经固化形成，则当紫外光固化胶填充承靠部122与承载壁112之间的间隙后，需通过调节孔114对紫外光固化胶进行紫外光照射使其固化形成填充件180。
另外，组装方法还可包括：
对第三透镜140背离第一透镜120的一侧的边缘及镜筒110之间点胶，以使得第三透镜140与镜筒110固定，进而将第一透镜120固定于容纳空间150内。
可以理解的是，在图6所示的实施例中，仅示出了组装过程中支撑件320对其中一个透镜进行支撑的示意图，在另一些实施例中，镜筒110还可具有其他的台阶结构，而镜头组件100内的其他透镜与该台阶结构相对并彼此间隔。例如第三透镜140的边缘与镜筒110的一个台阶结构相对且彼此间隔，则与第三透镜140的边缘相对的台阶结构也可开设调节孔114，而组装设备300设置有更多数量的支撑件320，以在组装过程中对第三透镜140的边缘起支撑作用。当然，组装设备300还可在组装过程中对镜头组件100的三个、四个或更多数量的透镜起支撑作用，调节孔114及支撑件320的数量均可根据透镜的数量具体设置，此处不再赘述。
