具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
正如背景技术部分所述，传统的摄像头的镜头结构的品质波动较大，良率较低。
发明人研究发现，在镜头结构内部靠近镜头结构通光孔一侧的第一片镜片距离镜头结构的焦距点较近，且入射光在射入该镜头结构时，先经过第一片镜片，因此，镜头结构中第一片镜片的光轴位置的对准度对于镜头结构最为敏感，通过动态调节第一片镜片的光轴位置可以得到一个高品质的镜头结构，提高镜头结构的良率。
但是，传统摄像头的镜头结构中，各镜片位于镜筒内部，只能通过在镜筒的侧面或顶面开槽以便调节第一片镜片的位置，调节好后，再对第一片镜片进行固定，并对该开槽进行密封，调节幅度较为有限，且调节较为不便，灵活性较差。
而且，当上述镜头结构出现品质问题时，难以区分是第一片镜片位置调节的问题还是其他镜片的组装问题。
有鉴于此，本申请实施例提供了一种镜头结构，如图1所示，该镜头结构包括：镜筒10；位于所述镜筒10第一端面的第一镜片30，所述第一镜片30包括聚光区域和位于所述聚光区域四周边缘的边缘区域；覆盖所述第一镜片30边缘区域的遮光结构40；位于所述镜筒10内部的至少一个第二镜片20。
需要说明的是，在本申请实施例中，所述镜筒的第一端面是指所述镜头结构在使用状态时，所述镜筒朝向待拍摄图像一侧的表面，也即所述镜筒朝向第一镜片一侧的外表面。还需要说明的是，在本申请实施例中，当所述至少一个第二镜片20包括多个第二镜片时，所述多个第二镜片可以相同，也可以不同，本申请实施例对此并不做限定，具体视情况而定。
在上述实施例的基础上，在本申请的一个实施例中，所述第一镜片30与所述遮光结构40固定粘接，所述第一镜片30与所述镜筒10固定粘接，以利用所述遮光结构40对所述第一镜片30的边缘区域进行覆盖，阻挡外界环境中的光线经所述第一镜片30的边缘区域进入所述镜筒10内部，但本申请实施例对此并不做限定，具体视情况而定。
具体的，在本申请的一个实施例中，所述第一镜片30与所述遮光结构40通过液体胶或双面胶固定粘接；所述第一镜片30与所述镜筒10也通过液体胶或双面胶固定粘接。下面以所述第一镜片30与所述遮光结构40通过UV热固胶固定粘接，所述第一镜片30与所述镜筒10也通过UV热固胶固定粘接，对本申请实施例所提供的镜头结构进行说明。但本申请实施例对此并不做限定，具体视情况而定。
在上述任一实施例的基础上，如图1所示，所述遮光结构40为聚酯薄膜，可选的，所述遮光结构40在平行于所述第一镜片30边缘区域的平面内的投影面积大于所述第一镜片30边缘区域在平行于所述第一镜片30边缘区域的平面内的投影面积，以便于所述遮光结构40完全覆盖所述第一镜片30的边缘区域和所述第一镜片30的侧壁，避免外界环境中的光线经第一镜片30的边缘区域和所述第一镜片30的侧壁进入镜筒10内部。
如图2所示，在本申请的另一个实施例中，所述遮光结构40包括塑料件41，所述塑料件41至少覆盖所述第一镜片30的边缘区域，以使得所述第一通光孔50的深度不小于所述第一镜片30聚光区域的厚度，对所述第一镜片30的聚光区域进行保护，降低所述第一镜片30的聚光区域被磨损的概率。
可选的，所述塑料件41的制作材料为聚碳酸酯(Polycarbonate，简称PC)，所述镜筒10的制作材料与所述塑料件41的制作材料相同，但本申请实施例对此并不做限定，具体视情况而定。
在本申请的一个实施例中，如图2所示，所述塑料件41完全覆盖所述第一镜片30的边缘区域和所述第一镜片30的侧壁，具体的，所述塑料件41包括水平部分和竖直部分，其中，所述水平部分完全覆盖所述第一镜片30的边缘区域表面，所述竖直部分遮挡所述第一镜片30的侧壁，可选的，在垂直于所述水平部分方向上，所述竖直部分的高度大于所述第一镜片30侧壁的厚度，以免外界环境中的光线在平行于所述水平部分的平面内射入所述第一镜片30。需要说明的是，在本申请实施例中，所述塑料件41可完全覆盖所述第一镜片30的边缘区域的表面和侧壁，而无需设置其他额外结构，结构较为简单。
在本申请的另一个实施例中，所述塑料件41仅覆盖所述第一镜片30边缘区域表面，在本申请实施例中，如图3和图4所示，所述遮光结构40还包括遮光件42，所述遮光件42至少覆盖所述边缘区域的侧壁(也即所述第一镜片30的侧壁)，用于对所述第一镜片30的侧壁进行遮光。具体的，在本申请的一个实施例中，如图3所述，所述遮光件42同时覆盖所述塑料件41和所述第一镜片30的侧壁；在本申请的另一个实施例中，如图4所示，所述遮光件42仅覆盖所述第一镜片30的侧壁，可选的，所述遮光件42还沿所述第一镜片30的厚度方向上延伸至覆盖部分所述塑料件41的侧壁和所述镜筒10的侧壁，但本申请实施例对此并不做限定，具体视情况而定。需要说明说明的是，在本申请实施例中，所述塑料件41和所述遮光件42组合以完全覆盖所述第一镜片30的边缘区域的表面和侧壁。本申 请实施例对此并不做限定，具体视情况而定。
还需要说明的是，在上述任一实施例中，为了进一步增强所述遮光结构40、所述第一镜片30和所述镜筒10之间的牢固度，在本申请的一个可选实施例中，所述遮光结构40与所述镜筒10之间也固定粘接。
相应的，本申请实施例还提供了上述任一实施例所提供的镜头结构的摄像头。具体的，所述摄像头包括：上述任一实施例所提供的镜头结构；；位于所述镜头结构中所述镜筒的第二端面的感光元件，所述第二端面为所述镜筒中与所述第一端面相对的一面；位于所述感光元件背离所述镜头结构一侧，与所述感光元件电连接的电路板。其中，所述电路板可以为PCB电路板，本申请实施例对此并不做限定。
具体工作时，所述镜筒结构用于聚集光线，所述感光元件用于感应所述镜筒结构聚集的光线，并将其转换成电信号后，再转换成数字信号传输给所述电路板，经所述电路板输出给终端，经所述终端的图像处理元件处理，形成图像。
由上可知，本申请实施例所提供的镜头结构及包括该镜头结构的摄像头中，所述第一镜片30设置于所述镜筒10的外部，调节幅度较大，便利性较强，灵活性较高。而且，本申请实施例所提供的镜头结构及包括该镜头结构的摄像头中，所述第一镜片30和包括所述至少一个第二镜片20的镜筒10独立设置，从而可以通过单独测试包括所述至少一个第二镜片20的镜筒10以及所述第一镜片30和所述镜筒10组装后的结构，来区分导致所述镜头结构出现品质问题的原因是所述至少一个第二镜片20的组装问题还是第一镜片30的位置设置问题。
相应的，本申请实施例还提供了一种镜头结构的制作方法，如图1和图5所示，该方法包括：
提供镜筒10，所述镜筒10内设置有至少一个第二镜片(图中未示出)；
如图5(A)所示，提供遮光结构40，所述遮光结构40具有第一通光孔；
在所述遮光结构40的第一表面固定第一镜片30，形成第一组装结构，所述第一镜片30包括聚光区域和位于所述聚光区域四周边缘的边缘区域，所述第一通光孔曝露所述聚光区域；
如图5(B)所示，在所述镜筒10的第一端面放置所述第一组装结构；
调节所述第一组装结构，直至所述镜头结构的解析度大于预设值；
如图5(C)和(D)所示，固定所述镜筒10和所述第一组装结构。
具体的，在上述实施例的基础上，在本申请的一个实施例中，提供镜筒10，所述镜筒10内设置有至少一个第二镜片包括：
提供镜筒10，并在所述镜筒10内放置至少一个第二镜片；检测所述镜筒10的解析度，以判断所述镜筒10内所述至少一个第二镜片的对准度；当所述镜筒10的解析度满足预设要求时，将所述镜筒10标记为符合组装要求的镜筒，用于后续与所述第一组装结构进行组装。
下面以所述遮光结构40为聚酯薄膜为例，对本申请实施例所提供的镜头结构的制作方法进行描述。
在上述任一实施例的基础上，在本申请的一个实施例中，在所述遮光结构40的第一表面固定第一镜片30，形成第一组装结构，所述第一镜片30包括聚光区域和位于所述聚光区域四周边缘的边缘区域，所述第一通光孔曝露所述聚光区域包括：
在所述遮光结构40的第一表面涂布粘接胶，所述遮光结构40具有第一通光孔，所述粘接胶包括UV热固胶；
在所述遮光结构40的第一表面放置第一镜片30，所述第一镜片30包括聚光区域和位于所述聚光区域四周边缘的边缘区域，所述第一通光孔曝露所述聚光区域；
利用UV光照射所述粘结胶位于所述边缘区域的部分，进行第一次UV固化，实现所述第一镜片30和所述遮光结构40的固定连接。
需要说明的是，由于所述遮光结构40为聚酯薄膜时，所述遮光结构40在平行于所述第一镜片30边缘区域的平面内的投影面积大于所述第一镜片30边缘区域在平行于所述第一镜片30边缘区域的平面内的投影面积，因此，为了便于后续所述遮光结构40与所述镜筒10的固定粘接，在利用UV光照射所述粘结胶位于所述边缘区域的部分，进行第一次UV固化，实现所述第一镜片30和所述遮光结构40的固定连接时，可选的，该方法还包括：利用辅助遮光结构对所述聚酯薄膜与第一镜片30的非交叠区域进行遮挡，以保持所述聚酯薄膜与所述第一镜片30非交叠区域的粘接性能。
还需要说明的是，在本申请的其他实施例中，当所述遮光结构40包括塑料件41和遮光件42时，如图4和图6所示，在所述遮光结构40的第一表面固定第一镜片30，形成第一组装结构，所述第一镜片30包括聚光区域和位于所述聚光区域四周边缘的边缘区域，所述第一通光孔曝露所述聚光区域包括：
如图6(A)和图6(B)所示，在所述塑料件41的第一表面涂布粘接胶，所述塑料件具有第一通光孔，所述粘接胶包括UV热固胶；在所述塑料件的第一表面放置第一镜片30，所述第一镜片30包括聚光区域和位于所述聚光区域四周边缘的边缘区域，所述第一通光孔曝露所述聚光区域；利用UV光照射所述粘结胶位于所述边缘区域的部分，进行第一次UV固化，实现所述第一镜片30和所述塑料件的固定连接。
待所述第一镜片30和所述塑料件的固定连接后，继续如图6(B)所示，在所述镜筒10的第一端面放置所述第一组装结构；调节所述第一组装结构，直至所述镜头结构的解析度大于预设值；如图6(C)所示，固定所述镜筒10和所述第一组装结构。待所述第一组装结构和所述镜筒10固定连接后，如图6(D)所示，再固定所述遮光件42，所述遮光件42至少覆盖所述边缘区域的侧壁。
在上述任一实施例的基础上，在本申请的一个实施例中，在所述镜筒10第一端面放置所述第一组装结构包括：
在所述镜筒10的第一端面涂布粘接胶，所述粘接胶包括UV热固胶；
将所述第一镜片30朝向所述镜筒10第一端面一侧，在所述第一端面放置所述第一组装结构。需要说明的是，在本申请实施例中，放置所述第一组装结构后，并非将所述第一组装结构固定住，而是确定所述第一组装结构的活动区域，以便在所述活动区域内调节所述第一组装结构，使得所述镜头结构的解析度大于预设值。
需要说明的是，由于不同的应用需求，对所述镜头结构的解析度要求不同，故本申请实施例对所述预设值的具体数值不做限定，具体视情况而定。
在上述任一实施例的基础上，在本申请的一个实施例中，调节所述第一组装结构，直至所述镜头结构的解析度大于预设值包括：
利用加持装置固定所述遮光结构40，通过移动所述遮光结构40调节所述第一镜片30的位置；
在各调节位置，检测所述镜头结构的解析度；
当所述镜头结构的解析度大于预设值时，不再移动所述第一组装结构的位置。
可选的，所述夹持装置包括吸嘴和/或采用动态调节技术的调节机台，但本申请实施例对此并不做限定，具体视情况而定。
具体的，在本申请的一个实施例中，调节所述第一组装结构，直至所述镜头结构的解析度大于预设值包括：
在所述镜筒10背离所述第一端面一侧放置感光元件；利用加持装置固定所述遮光结构40，通过移动所述遮光结构40调节所述第一镜片30的位置，实现所述第一镜片30与所述至少一个第二镜片20光轴的对准；在各调节位置，利用所述镜筒10与所述第一组装结构形成的镜头结构采集图像；分析所采集到的图像的清晰度，以判断所述镜头结构的解析度；当所述镜头结构的解析度不大于预设值时，调节所述第一组装结构的位置，重复上述图像采集与分析过程，直至所述镜头结构的解析度大于预设值，对所述镜头结构的当前位置进行固定。
需要说明的是，在上述实施例的基础上，在本申请的一个实施例中，在对所述镜头结构的当前位置进行固定之后，该方法还包括：对所述遮光结构40的四周施加压力和整平，以在获得理想形状的同时增加所述遮光结构40与所述第一镜片30、所述镜筒10之间的密封性，提高遮光效果。
在上述任一实施例的基础上，在本申请的一个实施例中，固定所述镜筒10和所述第一组装结构包括：
利用UV光，从所述镜筒10的底部照射所述粘接胶，进行第二次UV固化；
对所述镜筒10和所述第一组装结构构成的整体加热，进行热固化，实现所述镜筒10和所述第一组装结构的固定连接。
由前述分析可知，镜头结构中第一片镜片的光轴位置的对准度对于镜头结构最为敏感，而本申请实施例所提供的镜头结构及其制作方法中，将所述第一镜片30设置在所述镜筒壳体外侧，调节幅度较大，便利性较强，灵活性较高。而且，本申请实施例所提供的镜头结构及其制作方法，在所述镜头结构的解析度大于预设值时，再对所述第一镜片30的位置进行固定，从而使得所述第一镜片30的光轴与所述至少一个第二镜片20的光轴之间的对准度较高，提高所述镜头结构的品质。
此外，本申请实施例所提供的镜头结构及其制作方法，所述第一镜片30和所述至少一个第二镜片20独立设置，从而可以通过单独测试包括所述至少一个第二镜片20的镜筒以及所述第一镜片30和所述镜筒组装后的结构，来区分导致所述镜头结构出现品质问题的原 因是所述至少一个第二镜片20的组装问题还是第一镜片30的位置设置问题。
