Description

用于光学模组的焊接结构及其应用 技术领域
本发明涉及一光学模组领域，尤其涉及一装配有采用焊接固定方式固定的多群组镜头的光学模组，其中所述多群组镜头之间采用所述焊接结构彼此固定，进而提高所述光学模组的稳定性。
背景技术
光学模组被广泛地设置于摄像、监控等电子产品中，其中所述光学模组包括一线路板组件、一滤光片以及一镜头，其中所述线路板组件包括一线路板主体、一感光芯片、多个电子元器件以及一支架，其中所述感光芯片、所述电子元器件以及所述支架分别被安装于所述线路板主体，其中所述滤光片和所述镜头分别被安装于所述支架并且位于所述感光芯片的感光路径上。
传统地，无论是将所述感光芯片安装到所述线路板主体或者是将所述支架安装在所述线路板主体或者是将所述镜头安装于镜筒亦或者是将镜筒安装在所述支架，都是采用胶水等其他介质粘合固定的方式安装的，由于采用胶水等同类介质将其固定时，该类介质的热膨胀或收缩系数与需要被固定的结构表面材质热膨胀或收缩系数不同，从而使得通过所述胶水被相对固定的结构在受热冷却后容易发生变形，进而影响所述光学模组的性能，而该变形往往是发生在所述光学模组被组装后。尤其是当所述光学模组被安装于电子产品后，所述电子产品经常会在使用和关闭两种使用状态下转换，而当所述电子产品在使用状态时会发热，当所述电子产品转换至关闭状态时，会形成温度差，此时所述光学模组中采用胶水粘合固定的结构将会发生变形。
另外，由于采用胶水固定时，被胶水固定后的结构表面之间形成一定厚度的胶水，因此在设计的时候，需要在被胶水固定的两结构表面之间预设一定的空隙，这样不仅导致最终形成的光学模组体积变大，而且增加了设计的难度。
尤其是对于光学模组中的镜头而言，镜头是光学模组的一个重要部件，直接影响光学模组的成像品质。
随着智能化的不断发展，对光学模组的要求不断提高，比如在成像上越来越要求高像素，这也使得光学模组的镜头中镜片的数量不断增加，比如达到5至6六片。
保证光轴的一致，即保证各镜片的中心轴线的一致，并且和感光芯片的中心轴线一致，是保证良好的成像品质的基础。对于传统的镜头，通常是将多个镜片逐次组装于一个镜筒中，在组装过程中不可避免地，每一镜片和镜筒组装时都会存在一定的误差，最后，各镜片整体和镜筒之间组装形成一个累积误差，也就是单个镜头的组装误差。由此可以很容易了解到，镜片数量越多，累积误差越大，镜头整体的品质越低，且镜头生产过程中的良率也越低。
另一方面，对于传统的镜头，多个镜片组装于同一镜筒，各镜片之间的相对位置基本确定，不能进行调节，镜片一旦组装于镜筒内，镜头质量即确定，这也使得对于镜筒和镜片的加工精度要求较高。
值得一提的是，对于镜片数量较少的镜头，镜片的组装误差影响较小，因此整体的镜头对于生产以及模组的组装来说，可能存在更大的优势，但是当镜片的数量增多时，镜片数量越增多，由于镜头引起的问题越严重，因此对镜头的改进也更为急迫，因此如何在通过多镜片提供高像素的基础上，保证良好的成像品质以及生产过程中的良率，是需要去研究的一个重要方面。
还值得一提的是，镜头的镜片以及镜片和镜筒的组装关系直接影响镜头的质量，而对于光学模组，尤其是应用于一些智能设备的光学模组，如智能手机，其尺寸相对较小，因此如何结合现有的设备需求，充分利用镜头的结构，研究适宜实际生产应用的镜头也是需要考虑的方面。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
本领域技术人员应理解的是，在本发明的揭露中，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系，其仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此上述术语不能理解为对本发明的限制。
本发明提供一电子设备和光学模组以及用于光学模组的焊接结构，其中所述光学模组包括至少一第一模组组件、至少一第二模组组件以及至少一焊接结构，其中所述焊接结构包括至少一第一焊接件和至少一第二焊接件，其中所述第一焊接件被设置于所述第一模组组件，其中所述第二焊接件被设置于所述第二模组组件，优选地，所述第一焊接件被嵌入所述第一模组组件，其中所述第二焊接件被嵌入所述第二模组组件。本领域普通技术人员能够理解的是，所述第一焊接件和所述第二焊接件可以采用黏贴或者其它方式被分别设置于所述第一焊接件和所述第二焊接件，本发明不受此方面的限制。为使本领域技术人员能够理解本发明， 本发明以下实施例中，仅以所述第一焊接件和所述第二焊接件分别被实施为嵌入所述第一模组组件和所述第二模组组件为例进行说明。通过焊接所述第一焊接件和所述第二焊接件的方式使得所述第一模组组件和所述第二模组组件藉由所述焊接结构被稳定地连接。
值得一提的是，本发明中，焊接所述第一焊接件和所述第二焊接件的方式包括但不限于激光焊接、超声波焊接等。
更值得一提的是，在本发明另一实施例中，所述第一焊接件和所述第二焊接件可以是分别自所述第一模组组件和所述第二模组组件一体延伸而形成，本发明不受此方面的限制，为使本发明领域普通技术人员能够理解本发明，本发明实施例中仅以所述第一焊接件和所述第二焊接件被分别设置于所述第一模组组件和所述第二模组组件为例进行说明。
本领域普通技术人员能够理解的是，在本发明其他实施例中，所述焊接结构可以包括一第三焊接结构和一第四焊接结构，其中所述光学模组可以包括一第三模组组件或一第四模组组件，其中所述第三焊接件可以被设置于所述第二模组组件，其中所述第四焊接件可以被设置于所述第三模组组件，藉由焊接所述第三焊接件和所述第四焊接件，从而使得所述第三模组组件被连接于所述第二模组组件。
值得一提的是，所述第三焊接结构也可以被设置于所述第三模组组件，其中所述第四焊接件被设置于所述第四模组组件，藉由焊接所述第三焊接件和所述第四焊接件，从而使得所述第三模组组件和所述第四连接结果被相对固定。
所述第一模组组件和所述第二模组组件可以被实施为但不限于选择镜头与镜筒、镜筒与线路板组件、马达与感光组件、多群组镜头中的两群组单元等。为使本领域普通技术人员能够理解本发明，以下实施例中首先以多群组镜头中的两群组单元为例加以阐述，本领域普通技术人员能够理解，本发明中所述焊接结构可以被应用于连接所述光学模组中的任意两个需要被固定的两元件，本发明不受此方面限制，其中所述多群组镜头指的是，应用于所述光学模组中的镜头采用两组或两组以上的分体式镜头(在本发明以下实施例中称之为群组单元)组合而成。
传统的镜头，尤其是应用于光学模组的镜头，长期处于一种相对稳定且单一的结构方式，将多个镜片组装一个镜筒而构成，如前所述，当镜片数量较少，如两三片时，这种结构的组装误差影响相对较小，而随着对镜头以及光学模组高像素、高成像质量的要求，镜片数量增多，累积误差不断增大，传统的镜头结构严 重不适于对于镜头和光学模组的要求。而根据本发明，提供一多群组镜头，由多个群组单元组装形成一个整体的镜头，从而使得每个群组单元中的镜片数量较少，每个单元的组装误差较小，但是由各所述群组单元构成的所述多群组镜头的镜片总数较多，因此可以提供较高的像素，且累积误差较小。且各所述群组单元在组装形成所述多群组镜头的过程中，可以采用主动校准(Active Alignment，AA)的方式进行组装，使得各所述群组单元之间的相对误差减小，从而使得所述多群组镜头具有较好的光学一致性。且各所述群组单元通过一组装结构相互配合地组装，从而使得各群组单元稳定地组装形成所述多群组镜头，且配合的方式可以遮挡外部杂光进入所述多群组镜头内部，避免干扰所述多群组镜头的光学系统。且在一些实施方式中，各所述群组单元之间通过所述一焊接结构20，使得各所述群组单元快速、稳定地进行组装固定，从而提高生产效率。
参考图1至图12，所述多群组镜头100包括多个群组单元10和至少一焊接结构20，所述多群组镜头100适于多镜片的镜头，2片、3片或以上。
所述多群组镜头100适于被组装构成一光学模组300，特别适于被组装构成高像素的光学模组300。
所述多群组镜头100包括至少两群组单元10，各所述两群组单元共同构成所述多群组镜头100的整体光学系统。也就是说，所述多镜片的光学系统，由至少两个所述群组单元组合实现，而不是像传统的一体式镜头，通过一个独立的镜头实现。
值得一提的是，所述多群组镜头100的各群组单元中的镜片可以根据不同的需要进行分配组合，在本发明的这个实施例中，仅选择其中一种进行说明，本领域的技术人员应当理解的是，各所述镜片的数量以及分配方式并不是本发明的限制。
更具体地来说，所述多群组镜头100包括两所述群组单元，分别为一第一群组单元11和第二群组单元12。当所述第一群组单元11和所述第二群组单元12构成整体镜头时，所述第一群组单元11位于所述第二群组单元12的上方，所述第一群组单元11和所述第二群组单元12的光轴一致。也就是说，在本发明的＝实施例中，所述多群组镜头100的光学系统由所述第一群组单元11和所述第二群组单元12各自对应的两个光学系统共同构成。也就是说，在一定程度上，所述第一群组单元11和所述第二群组单元12各自独立存在时，并不能完成一个完 整镜头的功能，而当所述第一群组单元11个所述第二群组单元12相互配合时，构成一个可以达到成像质量要求的完整镜头。
进一步，所述第一群组单元11包括一第一承载部件111和至少一第一群组镜片112，所述第一群组镜片112被安装于所述的第一承载部件111，以便于构成一独立的部件。
所述第二群组单元12包括一第二承载部件121和至少一第二群组镜片122，所述第二群组镜片122被安装于所述第二承载部件121，以便于构成另一独立部件。
所述第一承载部件111被设置于所述第二承载部件121上方，以使得所述第一群组单元11和所述第二群组单元12的光路方向一致。
在本发明实施例中，所述第一焊接件21被设置于所述第一承载部件111，优选地，所述第一焊接件21被嵌入所述第一承载部件111。所述第二焊接件22被设置于所述第二承载部件121，优选地，所述第二焊接件22被嵌入所述第二承载部件121。当所述第一群组单元11被相对固定于所述第二群组单元12时，所述第一承载部件111被支撑于所述第二承载部件121，并且所述第一焊接件21被支撑于所述第二焊接件22，进一步地，在校准所述第一群组单元11和所述第二群组单元12后，通过激光焊接所述第一焊接件21和所述第二焊接件22的方式，进而能够使所述第一群组单元11的所述第一承载部件111和所述第二群组单元12的所述第二承载部件121彼此相对固定。
值得一提的是，通过上述方式固定时，由于所述第一焊接件21和所述第二焊接件22优选地采用金属材料制成，从而当所述多群组镜头100被设置于所述光学模组300并且所述光学模组300经常处于严峻环境(例如但不限于烘烤、高温高湿)等)环境中时，所述第一群组单元11和所述第二群组单元12之间的相对位置不会因热膨胀不均而发生较大的位移，从而使得所述多群组镜头10000能够保持稳定的光学性能。
还值得一提的是，在传统的一体式镜头中，镜片被逐次地安装于镜筒中，镜片可以被调整的范围很小，且一旦镜片被固定，镜片和镜筒相对位置固定。当所有的镜片被组装完成时，整个镜头的累积误差确定，不可被调整。而在本发明中，所述第一群组单元11和所述第二群组单元12各自可以独立地构成，相互之间没有影响，所述第一群组单元11和所述第二群组单元12被组装为整体的镜头时， 所述第一群组单元11和所述第二群组单元12可以被相对调整，从而可以进一步校准所述镜头，使其整体误差减小，特别地，可以进行立体空间不同方向的调整，比如六轴方向调整。
所述第一承载部件111包括一第一主体1111和一外延伸台1112，所述外延伸台1112自所述第一主体1111向外延伸。特别地，所述外延伸台1112自所述第一主体1111一体地水平向外延伸，从而形成一环形的帽檐结构，比如通过模具一体形成的方式形成。
在本发明的这个实施例中，所述外延伸台1112被设置于所述第一主体1111外部的中部位置，将所述第一主体1111区分为两部分，一部分位于所述外延伸台1112的上方，一部分位于所述外延伸台1112的下方，在所述第一群组单元11和所述第二群组单元12组装后，所述第一主体1111位于所述外延伸台1112的上方。
所述外延伸台1112可以被设置不同高度，比如在一些实施例中，设置比较小的高度，使得所述外延伸台1112的顶面低于所述第一主体1111的顶端。比如在一些实施例中，设置比较大高度，使得所述外延伸台1112的顶面和所述第一主体1111的顶端一致，从而使得所述多群组镜头100上部分具有不同形状。
所述第一主体1111具有一第一容纳腔11111、一第一上通光孔11112和一第一下通光孔11113。所述第一群组镜片112被容纳于所述第一容纳腔11111。
所述第一上通光孔11112位于所述第一主体1111上部，用于连通于外部，使得光线进入所述第一群组单元11，即，使得外部光线到达位于所述第一容纳腔11111内的所述第一群组镜片112。
所述第一下通光孔11113位于所述第一主体1111的下部，连通于所述第二群组单元12，以使得通过所述第一群组单元11的光线到达所述第二群组单元12。
所述第二承载部件121包括一第二主体1211和自所述第二主体1211一体延伸的一支撑台1212，其中在将所述第一群组单元11和所述第二群组单元12组合时，所述第一承载部件111的所述外延伸台1112被支撑于第二承载部件121的所述支撑台1212。
参考图3至图11，在本发明一实施例中，所述第一焊接件21被设置于所述外延伸台1112，其中所述第二焊接件22被设置于所述支撑台1212，当所述第一群组单元11和所述第二群组单元12经过校准之后，只需通过焊接所述第一焊接 件21和所述第二焊接件22即可将所述第一群组单元11和所述第二群组单元12相对固定。
所述第二主体1211具有一第二容纳腔12111、一第二上通光孔12112和一第二下通光孔12113。所述第二群组镜片122被容纳于所述第二容纳腔12111。
所述第二上通光孔12112位于所述第二主体1211的上部，用于连通于所述第一群组单元11，使得通过所述第一群组单元11的光线到达所述第二群组单元12。

在本发明中，所述第一焊接件21和所述第二焊接件22可以具有多种形状。例如，在本发明一实施例中，所述第一嵌入部211和所述第一连接部212为所述第一焊接件21的两侧部，具体的可以是所述第一焊接件21的上部和下部，也可以是所述第一焊接件21的左部和右部。所述第二嵌入部212和所述第二连接部212可以被设置为与所述第一焊接件21的所述第一嵌入部211具有相同的形状或不同形状，也就是说，所述焊接结构可以是相同形状的所述第一焊接件21和所述第二焊接件22之间的组合，也可以是不同形状的所述第一焊接件21和所述第二焊接件22之间的组合，本发明不受此方面的限制。
比如参考图2A，在本发明第一个实施例中的所述第一焊接件21，所述第一焊接件21和所述第二焊接件22适于被安装于具有一水平平面的所述第一模组组件和所述第二模组组件，如图5、图13A、图13B、图14B以及图15B所示的所述第一模组组件中。在本实施例中，所述第一焊接件21具有一环形结构，并且所述第一焊接件21的所述第一嵌入部211和所述第一连接部212具有不同的高度，以在所述第一嵌入部211和相邻的两个所述第一连接部212之间形成一嵌入空间200，供嵌入所述第一模组组件。
再比如参考图2B，在本发明第一个实施例中的所述第二焊接件22适于被安装于具有一水平平面的所述第一模组组件和所述第二模组组件。在本发明第一个实施例中的所述第二焊接件22的所述第一嵌入部211和所述第二连接部212具 有相同的高度。在本实施例中，所述第二焊接件22也被实施为一环形，且所述第二焊接件22的所述第二连接部222为一闭合的环形圈，所述第二焊接件22的所述第二嵌入部221为自所述第二连接部222径向延伸的凸出部。当所述第二焊接件22被设置于所述第一模组组件后，所述第二焊接件22的所述第二连接部222形成所述第二裸露表面220。
另外，在本发明中，所述第一焊接件21和所述第二焊接件22可以被实施为具有相同的形状结构，也可以被实施为具有不同的形状结构，本发明不受此方面的限制。
比如如图3A、图3B以及图3C所示，在本发明的第二个实施例中的所述第一焊接件21A和所述第二焊接件22A具有不同的结构。在本实施例中，所述第一焊接件21A和所述第二焊接件22A适于被设置于具有一竖直平面的所述第一模组组件和所述第二模组组件，如图8A、图8B、图10A以及图10B。在本实施例中，所述第一焊接件21A和所述第二焊接件22A分别被实施为一环形结构。所述第一焊接件21A在水平方向上靠外的部分形成所述第一连接部212A，所述第一焊接件21A在水平方向上靠内的部分形成所述第一嵌入部211A，当所述第一焊接件21A被设置于所述第一模组组件后，所述第一连接部212形成所述第一裸露表面210A。
此外，在本发明一个实施例中，所述第一焊接件21和/或所述第二焊接件22的形状可以被实施为一体形成的环形，也可以被实施为分体的至少两部分组成，本发明不受此方面的限制。
如图4A、图4B以及图4C所示。在本实施例中，所述第一焊接件21B和所述第二焊机件22B分别被实施为由分体的两部分组成。所述第一焊接件21B的每个部分都包括一第一嵌入部211B和一第一连接部212B。所述第二焊接件22B的每个部分都包括一第二嵌入部221B和一第二连接部222B。所述第一焊接件21B和所述第二焊接件22B分别被安装于所述第一模组组件和所述第二模组组件后，分别形成一第一裸露表面210B和一第二裸露表面220B，其中当所述第一焊接件21B和所述第二焊接件22B被焊接后，所述第一焊接件21B和所述第二焊接件22B相互连接。
本领域技术人员能够理解的是，在本发明其它实施例中，所述第一焊接件21B和所述第二焊接件22B还可以被实施为包括分体的三个或三个以上部分组成， 本发明不受此方面的限制。
由此可以看到本发明目的可被充分有效完成。用于解释本发明功能和结构原理的该实施例已被充分说明和描述，且本发明不受基于这些实施例原理基础上的改变的限制。因此，本发明包括涵盖在附属权利要求书要求范围和精神之内的所有修改。
