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，需要将待组装镜片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，不再赘述。
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：
工作台10，控制器11以及用于光学模组的主动对准的多个机械组件120。
工作台10上设有传送装置13，传送装置13上匀设有可跟随传送装置13运动的多个固定件130。其中，固定件可以是真空吸持件或可尺寸调节的夹具。固定件可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传送装置上的指定的位置处，并确保传送装置13运动过程中待组装光学件的平稳性。
图1中示意了以转盘形式存在的传送装置13，转盘形式的传送装置结构较为紧凑。可选的，传送装置13还可以是输送机，例如直线运动的传送带等。应当理解，本发明实例提供的传送装置包含但不仅限于转盘和输送机，还可包括其他可运动的输送机构。
其中，多个机械组件120中，每个机械组件都有各自的作业位置，相邻两个机械组件的作业位置之间的位置关系，可由多个固定件130中相邻两个固定件之间的位置关系确定。在本实施例中，可选的，可以用距离或夹角来 表示位置关系。
在一可行的实施方式中，相邻两个机械组件的作业位置之间的距离，是相邻两个固定件之间的距离的整数倍。例如，当多个固定件130设于直线运动的传送带上时，若相邻的两个固定件的距离为10cm，则相邻的两个机械组件的作业位置之间的距离可以为20cm、30cm或40cm等10cm的倍数。
在另一可行的实施方式中，相邻两个机械组件的作业位置之间的夹角，是多个固定件130中相邻两个固定件之间的夹角的整数倍。例如，当多个固定件130设于转盘上时，若相邻的两个固定件的夹角为15°，则相邻的两个机械组件的作业位置之间的夹角可以为15°、30°或45°等15°的倍数。如图1b所示，在图1b中，相邻两个固定件的夹角为45°，第一机械组件与第二机械组件的作业位置的夹角为45°；第二机械组件与第三机械组件的作业位置的夹角为90°；第三机械组件与第四机械组件的作业位置的夹角为90°。上述实施方式可以确保多工位能够同时工作，奠定了高效率光学模组组装的基础。
在本实施例提供的设备中，控制器11，可控制传送装置13运动，每当传送装置13运动设定角度和/或距离后，可控制传送装置13停止。其中，所述设定的角度可以与相邻两个固定件的夹角相等，所述设定的距离可以与相邻两个固定件的之间的距离相等。进而，传送装置13以设定的角度和/或距离进行一次运动后，传送装置13停止时，多个机械组件120的作业位置处可对应一固定件，控制器11可控制多个机械组件120对运动到各自作业位置处的固定件执行相应操作。
需要说明的是，在本实施例中，开始运动时，传送装置13上存在至少一个满足如下设定条件的固定件，该设定条件为：固定件与多个机械组件120中的任意一个机械组件位置对应。采用上述实施方式，能够确保传送装置13每一次运动设定角度和/或距离之后停止时，多个机械组件120中的每一机械组件的作业位置处都对应一固定件。进而，机械组件可在控制器11的控制下对运动到各自作业位置处的固定件执行相应操作。
可选的，如图2所示，多个机械组件120可包括：机械手121、对准机构122、电源组件123、第一图像采集设备124、以及点胶机构125。
在一可选实施方式中，机械手121，可向运动到机械手121的作业位置处的固定件上放置待组装光学件。其中，待组装光学件可以是光学模组的半成品，通过组装待组装光学件和待组装镜片可得到光学模组。机械手121可包括机械臂以及设于机械臂一端的真空吸持件或夹具。其中，该机械臂可在控制器11的运动指令下进行三轴或六轴的运动，真空吸持件或夹具可以从待组装光学件的上料架中抓取待组装光学件。
在一可选实施方式中，对准机构122，可向运动到对准机构122的作业位置处的待组装光学件的指定位置处放置待组装镜片，以得到待对准光学模组，并根据控制器11的对准指令进行运动以调整该待组装镜片的位置。其中，对准机构122包括：与控制器11电连接的第一机械臂，以及设于第一机械臂上的对准头。对准头可以是真空吸头或可调节的机械夹持头，本发明不做限制。
可选的，在一可能的情形下，需要向待组装光学件中组装两片甚至两片以上的光学镜片，一种可行的方式是逐片组装，一种可行的方式是多片同时组装。多片同时组装时，需要多个对准头分别夹持待组装镜片。
为满足同时组装多个待组装镜片的需求，如图3a以及图3b所示，对准机构122还包括：集成机构。集成机构与第一机械臂连接，且用于在第一机械臂上集成多个对准头。在上述实施方式中，第一机械臂可根据控制器11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122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11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运动，本发明实施例对此不作限制。
在一可选实施方式中，点胶机构125，可向运动到点胶机构125的作业位置处的待组装光学件执行点胶操作。在点胶操作中，点胶机构125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125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4所示，点胶机构125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11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4所示，为确保点胶机构125能够在正确的位置点胶，第二机械臂上还固设有第二图像采集设备。第二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11。控制器11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125。
可选的，本实施例中还可在对准机构122上设一UV灯，该UV灯与控制器11电连接，并且可接收控制器11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123，可向运动到对准机构122的作业位置处的待组装光学件供电，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，在一些待组装光学件中设有光源设备，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。为点亮待组装光学件的光源设备，可在工作台上设电源组件传送机构。该电源组件传送机构可将电源组件的输出端传送至运动到对准机构的作业位置处的待组装光学件的电源输入端。
应当理解的是，针对不设有光源设备的待组装光学件，例如摄像头模组的半成品，为使这类待组装光学件成像，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，针对运动到对准机构的作业位置处的固定件上的待对准光学模组，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进行控制。
在一可选实施方式中，第一图像采集设备124，可采集待对准光学模组成像的光斑并反馈给控制器11。需要说明的是，第一图像采集设备124可设于目标想要组装得到的光学模组的标准出光方向，进而在不断调整待组装镜片的位置以实现对准的过程中，第一图像采集设备124拍摄到的光斑才具有可参考的价值。
在一可选实施方式中，控制器11，可根据第一图像采集设备124反馈的光斑的质量生成对准指令并输出给对准机构122。光斑的成像质量，可包括光斑的位置以及光斑的大小，通过分析光斑质量以及光斑大小可判断待组装镜片是否已对准。
需要说明的是，可选的，在多个固定件130中，每一固定件均可设用于检测该固定件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11。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11。控制11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，避免机械组件产生空操作。
例如，运动到机械手121的作业位置处的固定件上已经放置了待组装光学件，此时控制器11可向机械手121发送停止作业指令，以避免重复作业。再例如，运动到点胶机构125的作业位置处的固定件上没有待组装光学件，此时控制器11可向点胶机构125发送停止作业指令，以避免点胶机构125在空的固定件上点胶。
需要说明的是，多个机械组件120包含上述记载的机械手121、对准机构 122、电源组件123、第一图像采集设备124、以及点胶机构125，但并不仅限于上述记载的机械组件。也就是说，本发明提供的光学模组组装设备还可包括其他所需要的机械组件，例如，下料机械手，下料机械手可在得到光学模组之后，将光学模组从固定件上转移至下料区。再例如，产品贴标组件，可在装配得到的光学模组上粘贴产品标签。
在本实施例中，传送装置上的固定件跟随传送装置运动，用于光学模组的主动对准的多个机械组件可在固定件运动停止时，多工位同时对运动到各自作业位置处的固定件执行相应操作。进而，随着传送装置的运动，固定件可依次进入每一个组装操作环节，多个机械组件也可依次对运动到其作业位置的固定件执行相应操作，进而在保证光学模组的组装精度的同时，提升组装效率。
除此之外，采用第一图像采集设备在对准的过程中实时拍摄成像光斑，并根据成像光斑的质量调整待组装镜片的位置，可有效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5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5，该方法包括：
步骤501、在传送装置运动设定的角度和/或距离时，控制所述传送装置停止运动。
步骤502、控制多个机械组件对运动到各自作业位置处固定件执行相应操作。
步骤503、在所述多个机械组件完成各自对应的操作时，控制所述传送装置进行运动。
在步骤501中，该设定的角度，可以由传送装置上的多个固定件之间的夹角确定。例如，传送装置上的多个固定件之间的夹角为45°，那么可设定传送装置每一次的运动角度为45°。该设定的距离，可以由传送装置上的多个固定件之间的距离确定。例如，传送装置上的多个固定件之间的距离为 10cm，那么可设定传送装置每一次的运动角度为10cm。
在步骤502中，多个机械组件可包括机械手、对准机构、电源组件、第一图像采集设备、以及点胶机构。
控制多个机械组件对运动到各自作业位置处的固定件执行相应操作，可包括如下操作：控制机械手向运动到机械手的作业位置处的固定件放置待组装光学件；以及，控制点胶机构向运动到点胶机构的作业位置处的待组装光学件进行点胶操作；以及，控制电源组件向运动到对准机构的作业位置处的待组装光学件供电，以及控制该对准机构向该待组装光学件放置待组装镜片以得到待对准光学模组，并根据对准指令调整该待组装镜片的位置；以及，控制第一图像采集设备采集该待对准光学模组的成像的光斑并根据光斑的质量生成所述对准指令并输出给所述对准机构。
可选的，在控制多个机械组件对运动到各自作业位置处的固定件执行相应操作之前，本实施例中，可通过每一固定件上设置的传感器检测该固定件上是否放置待组装光学件，根据检测结果向该固定件所在作业位置对应的机械组件下发相应的作业指令，例如启动作业指令或停止作业指令。
应当理解，在存在操作对象的情况下，上述在机械手的作业位置处、点胶机构的作业位置处以及对准机构的作业位置处的操作是同时进行的，以达到较高的组装效率。
在步骤503中，所述多个机械组件完成各自对应的操作时，可控制传送装置再一次运动，以将当前作业位置上的固定件送入下一作业位置，并将上一作业位置的固定件接入当前作业位置。
在本实施例中，传送装置上的固定件跟随传送装置运动，用于光学模组的主动对准的多个机械组件可在固定件运动停止时，多工位同时对运动到各自作业位置处的固定件执行相应操作。进而，随着传送装置的运动，固定件可依次进入每一个组装操作环节，多个机械组件也可依次对运动到其作业位置的固定件执行相应操作，进而在保证光学模组的组装精度的同时，提升组装效率。
图6是本发明另一实施例提供的光学模组组装方法的方法流程图。以下部分将结合图6，以多个固定件中的任一固定件为例，对本发明实施例提供的光学模组组装方法进行具体阐述。为描述方便，将该任一固定件标记为第一固定件。如图6所示，该方法包括：
步骤601、在第一固定件运动到机械手的作业位置处时，控制传送装置停止运动，并控制机械手向第一固定件放置待组装光学件。
步骤602、在放置完成后控制传送装置进行运动，并在第一固定件运动到点胶机构的作业位置处时，控制传送装置停止运动。
步骤603、控制点胶机构在第一固定件上的待组装光学件上的特定位置处点UV胶。
步骤604、在点完UV胶后控制传送装置进行运动，并在第一固定件运动到对准机构的作业位置处时，控制传送装置停止运动。
步骤605、控制电源组件向第一固定件上的待组装光学件供电。
步骤606、控制对准机构向第一固定件上的待组装光学件放置待组装镜片，得到待对准光学模组。
步骤607、控制第一图像采集设备采集第一固定件上的待对准光学模组成像的光斑。
步骤608、判断该光斑的质量是否符合预设的质量要求；若不符合，执行步骤609，若符合，执行步骤610。
步骤609、根据该光斑的质量生成对准指令，并根据对准指令控制对准机构调整待组装镜片的位置，并执行步骤607。
步骤610、控制位于对准机构上的UV灯点亮以加速固化UV胶，得到组装完成的光学模组。
需要说明的是，本实施例仅仅记载了本发明提供的光学模组组装方法的一可选实施方式，并非本发明的全部实施内容。在本实施例中，步骤603中先执行了点胶操作，在点胶完成之后进入步骤604开始执行对准操作，然而 实际执行时，本发明对点胶和对准的顺序并不做限制，可以先执行对准过程，在对准结束(光斑符合设定质量要求)之后，再进行点胶。
可选的，在控制点胶机构向运动到所述点胶机构的作业位置处的待组装光学件进行点胶操作时，可先通过点胶机构中的第二图像采集设备获取待组装光学件的实时图像；根据该实时图像，确定点胶位置，并根据该点胶位置，控制点胶机构中的第二机械臂带动UV针筒进行点胶操作。通过执行上述过程，能够避免点胶位置出现错误，提高了光学模组组装的成品质量。本实施例中，在组装待组装镜片的过程中，第一图像采集设备实时反馈成像光斑的质量，控制器根据光斑的质量实时生成对准指令，对准机构根据对准指令适时调整待组装镜片的位置，并在光斑的质量符合设定的质量要求时，固定待组装镜片得到光学模组。通过这样的组装方式，有效减少了光学模组的装配公差，兼顾了光学模组的组装效率以及组装精度。
另外，在上述实施例及附图中的描述的一些流程中，包含了按照特定顺序出现的多个操作，但是应该清楚了解，这些操作可以不按照其在本文中出现的顺序来执行或并行执行，操作的序号如101、102等，仅仅是用于区分开各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的消息、设备、模块等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之 内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
