但是，上述根据成像结果主动对准光学模组镜片的方式仍然存在不够高效的缺陷。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在本发明的下述实施例中，光学模组指的是对准完成并固定后的完整产品；待对准光学模组，指的是组装过程中的光学模组，其可能处于未对准状态，也可能处于已对准状态；待组装光学件，指的是光学模组的半成品，需要将待组装光学对准组装在其指定的位置并固定后才能够得到光学模组。以下所提到的上述概念，可参照上述解释进行理解，不再追逐。
在一种光学模组的组装方式中，可根据待对准光学模组的成像效果实时调整待对准光学模组中的待组装镜片的位置。当存在需同时组装的多个待对 准光学模组时，需要依次点亮待对准光学模组的物方的光源，并依次对镜片进程对准操作，这样的操作过程效率较低。为解决上述缺陷，本发明提供了如图1a所示的光学模组组装设备。
图1a为本发明一实施例提供的光学模组组装设备的结构示意图，结合图1a，该设备包括：
用于分别固定多个待组装光学件的多个固定件10、用于将多个待组装镜片分别放置到多个待组装光学件的指定位置处以得到多个待对准光学模组的对准机构11，以及用于给多个待对准光学模组供电的电源组件12；以及，入光面S i靠近多个待对准光学模组的分光棱镜13、靠近分光棱镜13的第一出光面S o1且与第一出光面S o1同轴的第一彩色图像采集设备14，以及靠近分光棱镜13的第二出光面S o2且与第二出光面S o2同轴的第二彩色图像采集设备15。
其中，第一彩色图像采集设备14和第二彩色图像采集设备15分别用于采集多个待对准光学模组对应的多个成像光斑的位置及大小，并反馈至控制器16；控制器16用于根据多个成像光斑的位置和/或大小确定不符合质量要求的光斑并生成相应的对准指令，以及根据不符合质量要求的光斑的颜色确定需调整的待组装镜片，并将对准指令输出至夹持需调整的待组装镜片的对准机构，以调整需调整的待组装镜片的位置。
其中，成像光斑的位置，是指在第一彩色图像采集设备14拍摄到的包含待对准光学模组及其成像光斑的图像中，成像光斑相对于待对准光学模组的像的中心点的上下左右位置，如图1b所示。
需要说明的是，在图1a的虚线框内，除所标注的固定件10、对准机构11以及电源组件12之外，A1ˉA3是待组装镜片的一种示意，B1ˉB3是待组装光学件所包含的反射镜的一种示意，C1ˉC3是待组装光学件内部的光源设备或外部光源设备的一种示意，D是用于改变光路方向的反射镜的一种示意。第i组待对准光学模组主要可由Ai与Bi组成，其中，i为整数，且i大于零。当然，应当理解的是，上述包括Ai、Bi、Ci、D的光路结构示意仅仅是为了便于说明本发明的技术方案，其对本发明的本质不构成限制。当光学模组内部 结构或功能产生变化时，此部分光路结构应随之变化，不再赘述。除此之外，图1a中以三组待对准光学模组为例对本发明进行图示，但本发明提供的设备并包括但不仅限于三组待对准光学模组的同时组装。
针对每一组待对准光学模组而言，物方光源点亮时，物方光源可经待对准光学模组透出。透出的光，经分光棱镜13后，被分光棱镜13的分光面分成两束，且这两束光分别朝着不同方向传播。
可选地，在本实施例中，分光棱镜13可由两个直角棱镜的斜棱面胶合而成，且胶合面上镀有透射率和反射率为1:1的半透半反介质膜。进而，从分光棱镜13的入光面S i入射的光线，可经半透半反介质膜分成两束光强接近、方向垂直的光束。其中，经半透半反介质膜反射的光束可从第一出光面S o1透出，经半透半反介质膜透射的光束可经第二出光面S o2透出。进而，第一彩色图像采集设备14和第二彩色图像采集设备15可分别拍摄到其视角范围内的图像。
应当理解的是，为保证光学模组的光学性能，在每一组光学模组的组装过程中，待组装镜片的对准包括待组装镜片针对待组装光学件在XYZ三个轴向上分别对准。其中，Z轴坐标可表示待组装镜片和待组装光学件的中心点之间的距离，X、Y轴坐标表示待组装镜片相对于待组装光学件的上下左右偏移量。
以一组待对准光学模组为例，在一种可行的实施方式中，控制器16可根据第一彩色图像采集设备14拍摄到的包含该待对准光学模组的成像光斑以及该待对准光学模组的图像，分析该待对准光学模组中的待组装镜片相对于待对准光学模组的上下左右位置。图1b示意了第一彩色图像采集设备14拍摄到的包含有待对准光学模组及其成像光斑的图像，在图1b所示的XY平面中，光斑在待对准光学模组的像的右下方。若以待对准光学模组的像的中心为对准参考点，则光斑的位置可表征待组装镜片并未对准。
在一种可行的实施方式中，控制器16可根据第二彩色图像采集设备15拍摄到的包含该待对准光学模组的成像光斑的图像中所展示的光斑的大小， 分析该待对准光学模组中的待组装镜片的中心点相对于待组装光学件的中心点的距离。
在确定待组装镜片相对于待组装光学件的上下左右位置及其中心点之间的距离后，控制器16可生成相应的对准指令，并将该对准指令发送至夹持该待组装镜片的对准机构，以使对准机构11进行三轴或六轴运动以调整待组装镜片的位置。
可选的，当待组装镜片相对于待组装光学件的上下左右位置不满足预设要求时，控制器16可控制相应的对准机构11在X或Y方向上运动，以不断调整待组装镜片的位置直至满足要求。当待组装镜片与待组装光学件的中心点之间的距离不满足预设要求时，控制器16可控制相应的对准机构11在Z方向上运动，以不断调整待组装镜片的位置直至满足要求。
可选的，当同时执行多组待组装学模组的组装操作时，为保证控制器16能够识别出每一组待对准光学模组对应的光斑并进行正确的对准控制，本实施例中，可采用不同颜色的光源分别使待对准光学模组成像。进而，第一彩色图像采集设备14和第二彩色图像采集设备15可拍摄到具有不同颜色的多组光学模组的成像光斑。控制器16接收到第一彩色图像采集设备14以及第二彩色图像采集设备15反馈的图像后，可首先根据图像中的光斑的颜色确定这些光斑分别是哪一组待对准光学模组成像得到的，以建立光斑和待对准光学模组的对应关系。
针对每种颜色的光斑，控制器16可进一步根据该光斑的位置和/或大小，分析与该光斑对应的待对准光学模组中的待组装镜片是否已对准，若没有对准，则生成相应的对准指令，并将该对准指令发送至夹持该待组装镜片的对准机构。进而，该对准机构可进行运动以调整该待组装镜片的位置直至光斑的位置和大小均满足设定要求。
如图2a以及图2b所示，其中，格纹标识的光斑1为红色光斑，竖条纹标识的光斑2为绿色光斑，斜条纹标识的光斑3位黄色光斑。在图2a中，第一彩色图像采集设备14拍摄到了三个不同颜色的光斑以及待对准光学模组的 像，从图2a中，可以分析出三个不同颜色的光斑分别与待对准光学模组的像的中心点的位置关系。在图2b中，第二彩色图像采集设备15拍摄到了三个不同颜色的光斑，从图2b中可以分析出三个不同颜色的光斑各自的大小。
以下部分将以一个实际的例子对本发明实施例进行进一步阐述。例如，假设在图1中，由待组装镜片A1与待对准光学模组B1组成第1组待对准光学模组的物方光源为红色光源，由待组装镜片A2与待对准光学模组B2组成第2组待对准光学模组的物方光源为绿色光源，由待组装镜片A3与待对准光学模组B3组成第3组待对准光学模组的物方光源为黄色光源。三组待对准光学模组同时成像时，第一彩色图像采集设备14和第二彩色图像采集设备15可分别采集到三种颜色光斑的位置及大小，并反馈至控制器16。假设控制器16根据光斑的位置和/或大小确定绿色的光斑不符合质量要求，则可根据绿色光斑的位置和/或大小生成对准指令，并将该对准指令输出至夹持待组装镜片A2的对准机构以调整待组装镜片A2的位置。
可选的，为确保第一图像采集设备14不仅能够拍摄到待对准光学模组的成像光斑，还能够拍摄到待对准光学模组，可在设置第一图像采集设备14与分光棱镜13之间的距离时，适当增大该距离以使该距离满足第一图像采集设备14拍摄待对准光学模组的需求。
可选的，为缩小设备体积并保证第一彩色图像采集设备14对待对准光学模组的拍摄质量，如图3所示，本实施例可在第一彩色图像采集设备14与分光棱镜13之间设置正透镜17，其中，正透镜17与第一彩色图像采集设备14同轴。进而，具有正光焦度的正透镜17可以辅助扩大第一彩色图像采集设备14的视场角。可选的，正透镜17可以是一个单透镜，也可以是透镜组。
在一可选实施方式中，正透镜17可以包括一非球面透镜，非球面透镜可以使得第一彩色图像采集设备14拍摄到的光斑具有更小的球差，进而更精确地分析光斑与待对准光学模组的相对位置。
在本发明实施例中，多个固定件10可以是真空吸持件或可尺寸调节的夹具。多个固定件10中的每个固定件可分别固定放置于其上的待组装光学件， 确保待组装光学组件精确地放置在转盘上的指定的位置处。
可选的，每一固定件上均可设有用于检测其上是否放置待组装光学件的传感器。例如，可在固定件的底部设压力传感器，若固定件上已放置待组装光学件，则压力传感器可检测到压力变化并将该压力变化发送至控制器16。例如，可在固定件上设红外或超声波传感器，若固定件上已放置待组装光学件，则红外或超声波传感器可检测到收发信号的时间差的改变，并将该改变发送至控制器16。控制16可根据上述传感器发送的信号判断固定件上是否有待组装光学件，进而可生成相应的作业指令，避免对准机构11、点胶机构18或其他机构产生空操作。
可选的，对准机构11可以包括与多个独立的对准机构，以满足同时组装多组光学模组的需求。可选的，对准机构11也可包括多个集成的对准头。当包括多个集成的对准头时，对准机构11包括：与控制器16电连接的第一机械臂，设于第一机械臂上的集成机构，集成机构上集成有多个对准头。如图4a以及图4b所示，第一机械臂可根据控制器16的控制指令进行X、Y、Z方向上的三轴运动，集成机构上的多个对准头也可独立进行X、Y、Z方向上的三轴运动。第一机械臂可将待组装镜片从上料架搬移至对准机构11的作业位置，集成机构上的多个对准头可分别将所抓取的待组装镜片放置到其理论位置。当然，第一机械臂以及集成机构上的多个对准头也可以在控制器16的控制指令下进行六轴运动(X，Y，Z，θX，θY，及θZ)甚至所需的其他多轴向运动，本发明实施例对此不作限制。
在一可选实施方式中，如图1a以及图3所示，本实施例还包括点胶机构18。点胶机构18可向待组装光学件执行点胶操作。在点胶操作中，点胶机构18可将特定的胶水通过涂抹、灌封或点滴的方式滴到待组装光学件上，使得点胶处具有一定粘性，进而在待组装镜片对准后，固定该待组装镜片，最终得到光学模组成品。点胶机构18可以在待组装镜片对准之前或对准之后执行点胶操作，本实施例对其顺序不做限制。
在本实施例中，如图5所示，点胶机构18包括：与控制器电连接的第二 机械臂，以及固定在第二机械臂上的UV点胶针筒。第二机械臂可在控制器16的控制下，带动UV点胶针筒至指定的点胶位置，并由UV点胶针筒执行点胶操作。其中，UV点胶针筒中存放有UV(Ultraviolet Rays)胶，即无影胶，又称光敏胶或紫外光固化胶，其粘结度高，固化迅速，可间接提升光学模组的组装效率。
可选的，如图5所示，为确保点胶机构18能够在正确的位置点胶，第二机械臂上还固设有第三图像采集设备。第三图像采集设备可在点胶之前拍摄待组装光学件的实际图像，并将拍摄到的图像发送至控制器16。控制器16根据接收到的图像进行识别，确定点胶处并发送具体的点胶指令至点胶机构18。
可选的，本实施例中还可在对准机构11上设一UV灯，该UV灯与控制器16电连接，并且可接收控制器16的固化指令，在待组装镜片对准后点亮，以加速UV胶的固化，提升光学模组的组装效率。
在一可选实施方式中，电源组件12，可向待对准光学模组供电，以使待对准光学模组成像。可选的，根据光学模组的性能不同，在一些待对准光学模组中设有光源设备，例如微投影模组的半成品。光源设备点亮后，可在待对准光学模组的像方成像。
应当理解的是，针对不设有光源设备的待对准光学模组，例如摄像头模组的半成品，为使这类待对准光学模组成像，本实施例提供的光学模组组装设备还包括一光源设备。可选的，针对待对准光学模组，光源设备位于该待对准光学模组的物方，可产生平行光使得待对准光学模组成像。该光源设备可与电源组件连接，其开关状态可由控制器16进行控制。
本实施例中，同时将多组待对准光学模组加入组装进程，在组装的过程中，采用不同颜色的光源设备分别使多组待对准光学模组成像，并采用彩色的图像采集设备在采集光斑位置及大小的同时，采集光斑的颜色信息。进而控制器可根据光斑的位置和/或大小及颜色，区分出哪些待对准光学模组中的待组装镜片需要进一步对准及如何对准，并生成对准指令控制相应的对准机构进行对准运动，极大提升了光学模组的组装效率。
除此之外，在本实例中，针对每一组待对准光学模组，通过使未组装完成的光学模组成像，并采用分光棱镜以及两组图像采集设备分别在两个不同方向获取其所成的像以和/或光学模组的像，进而控制器可以根据两组图像采集设备采集到的成像结果确定待组装镜片在三个轴向上是否均已对准，并在没有对准的情况下不断控制对准机构带动待组装镜片进行位置调整。上述三轴向同时反馈的对准过程，有效地减小整个光学模组的装配公差，提升了光学模组的组装精度，有效确保了光学模组的光学性能。
图6是本发明一实施例提供的光学模组组装方法的方法流程图，结合图6，该方法包括：
步骤601、控制对准机构将多个待组装镜片分别放置到多个待组装光学件的指定位置处，以得到多个待对准光学模组。
步骤602、控制电源组件给所述多个待对准光学模组供电，以使所述多个待对准光学模组成像。
步骤603、通过第一彩色图像采集设备和所述第二彩色图像采集设备分别采集所述多个待对准光学模组对应的多个成像光斑的位置及大小，并反馈至控制器。
步骤604、根据所述多个成像光斑的位置和/或大小确定不符合质量要求的光斑并生成相应的对准指令，以及根据所述不符合质量要求的光斑的颜色确定需调整的待组装镜片。
步骤605、将所述对准指令输出至夹持所述需调整的待组装镜片的对准机构，以调整所述需调整的待组装镜片的位置。
在本实施例中，在待组装镜片的对准之前或对准之后，控制器可控制点胶机构可以在待对准光学模组的指定位置处点UV胶。在对准完成之后，控制器可控制对准机构上的UV灯点亮以对点胶处进行照射，进而加速UV胶的固化，提升组装效率。
在实施例中，同时将多组待对准光学模组加入组装进程，在组装的过程中，采用不同颜色的光源设备分别使多组待对准光学模组成像，并采用彩色 的图像采集设备在采集光斑位置及大小的同时，采集光斑的颜色信息。进而控制器可根据光斑的位置和/或大小及颜色，区分出哪些待对准光学模组中的待组装镜片需要进一步对准及如何对准，并生成对准指令控制相应的对准机构进行对准运动，极大提升了光学模组的组装效率。

    控制对准机构将多个待组装镜片分别放置到多个待组装光学件的指定位置处，以得到多个待对准光学模组；
    控制电源组件给所述多个待对准光学模组供电，以使所述多个待对准光学模组成像；
    通过第一彩色图像采集设备和所述第二彩色图像采集设备分别采集所述多个待对准光学模组对应的多个成像光斑的位置及大小，并反馈至控制器；
    根据所述多个成像光斑的位置和/或大小确定不符合质量要求的光斑并生成相应的对准指令，以及根据所述不符合质量要求的光斑的颜色确定需调整的待组装镜片；
    将所述对准指令输出至夹持所述需调整的待组装镜片的对准机构，以调整所述需调整的待组装镜片的位置。
