Description

摄像模组及其镜头组件和组装方法 技术领域
本发明涉及一摄像技术领域，特别涉及一摄像模组及其镜头组件和组装方法。
背景技术
滤光片能够对一定波段的光进行选择，以起到减小杂光的作用，被广泛地应用于摄像模组，以提高摄像模组的成像质量。比如说，滤光片能够过滤光线中的红外光，以利于避免摄像模组获取的图像色彩出现失真的问题。
具体来说，参照附图1，现有的一摄像模组100P包括一镜头组件101P、一镜座102P、一线路板103P、一感光芯片104P以及一滤光片105P，其中所述镜头组件101P被安装于所述镜座102P，所述感光芯片104P被连接于所述线路板103P，所述镜座102P被贴附于所述线路板103P，且所述镜座102P支撑被装贴于所述镜座102P的所述滤光片105P。进一步地，所述镜头组件101P和所述滤光片105P被保持于所述感光芯片104P的感光路径，来自被拍摄物体的光线依次经过所述镜头组件101P和所述滤光片105P后成像于所述感光芯片104P。
现有的另一摄像模组200P包括一镜头组件201P、一模塑基座202P、一线路板203P、以及一感光芯片204P以及一滤光片205P，其中所述模塑基座202P一体成型于所述线路板203P，所述镜头组件201P被安装于所述模塑基座202P，所述滤光片105P被贴装于所述模塑基座202P。或者，现有的摄像模组200P进一步包括一支撑架206P，所述滤光片205P被贴装于所述支撑架206P，所述支撑架206P被贴装于所述模塑基座202P，并使得所述滤光片205P被保持于所述镜头组件201P和所述感光芯片204P之间。进一步地，所述镜头组件201P、所述滤光片205P被保持于所述感光芯片204P的感光路径，来自被拍摄物体的光线依次经过所述镜头组件201P和所述滤光片205P之后成像于所述感光芯片204P。
但是，在上述的摄像模组的组装和使用的过程中，都存在共同的问题。首先，如若所述滤光片和所述感光芯片之间的距离较近，所述滤光片上极小的污点、尘埃或是划损容易在感光芯片上成像，进而影响所述摄像模组的成品良率，造成所述摄像模组的制造成本上升。
其次，通常在贴装完成所述滤光片之后，需要将所述线路板、所述感光组件以及所述贴附有滤光片镜座等组合件运输至不同的车间或是工位进行后续的组装工序。在运输过程中，所述滤光片的上表面被裸露在外，增大了所述滤光片沾染尘埃的风险，并且容易造成所述滤光片在操作过程中被划伤，进而使得所述滤光片在运输过程中被污染或是刮花，以至于造成所述摄像模组的成品良率降低，生产成本升高。
还有，所述滤光片被设置于所述镜座时，所述镜座需要避让贴装于所述线路板的电气元件，造成所述镜座的高度增加，使得所述摄像模组的整体高度被抬升。所述线路板而所述滤光片被贴装于所述模塑基座时，需要特别增设限位所述滤光片的所述限位台于所述模塑基座，不仅增加了物料成本，而且增大了所述摄像模组的体积。所述滤光片被贴装于所述支撑架时，需要先将所述支撑架贴装于所述模塑基座，增加了组装工序，延长了组装周期，同样会增加了生产成本。
再次，设置有滤光片的镜座由于需要贴附滤光片必须要有支撑滤色片的支撑臂)以及镜 座本身成型厚度(0.2mm极限)限制，同时需要避让其他元器件，占用了模组整体高度空间,导致模组高度无法进一步降低。
而且，目前滤光片贴附外，还需要进行额外的丝印工序减少杂光问题的产生，部分杂光是因为光线在镜头和滤光片之间反复反射导致的，由于滤光片安装于镜头下方，滤光片和镜片非有效光学区域之间的空间大，杂光反射容易发生，导致必须进行额外的遮光工艺。
此外，目前的摄像模组产生的部分杂光是由于光线在镜头和滤光片之间反复反射导致的，由于滤光片安装于镜头下方，滤光片和镜片非有效光学部之间的空间大，杂光反射容易发生，导致必须进行额外的遮光工艺，具体地，滤光片贴附完成后，还需要额外设置一遮光部，利用喷漆、涂墨、丝印或是光刻等工艺形成所述遮光部，使得所述遮光部被环绕地设置于所述滤光片的有效光学部，以减少杂光问题的产生，增加额外的工艺，延长了摄像模组的组装周期。而且，滤光片与邻近的镜片之间相对应的面积越大，两者之间相对应的反射区域的面积越大，摄像模组产生的杂光越多。
还有，在组装的过程中，通过激光测高的方法能够获取所述感光芯片的准确位置，并通过采取多点激光测高的方法能够获取所述感光芯片所采在平面的参数，进而调整所述镜筒组件的位置，以实现快速安装。但是，在现有的组装过程中，都是先将所述感光芯片固定地保持于所述感光芯片的上方，再进行镜头组件的安装，尽管激光能够透过所述滤光片，但所述滤光片的存在影响激光测量的准确性，以使得所述镜头组件的安装容易出现偏差，以使得所述镜头组件的像面和所述感光芯片的成像区域所在的平面之间存在较大的偏差，进而难以采取激光多点测高的方法来组装所述摄像模组，降低了所述摄像模组的组装效率。

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。
可以理解的是，术语“一”应理解为“至少一”或“一个或多个”，即在一个实施例中，一个元件的数量可以为一个，而在另外的实施例中，该元件的数量可以为多个，术语“一”不能理解为对数量的限制。
参照说明书附图2A至图4A，根据本发明的一较佳实施例的一摄像模组100及其组装方法将在接下来的描述中被阐述，其中所述摄像模组100包括一镜头组件10、一感光芯片20以及至少一线路板组件30，其中所述感光芯片20被导通地连接于所述线路板组件30，所述镜头组件10能够被快速地安装于所述线路板组件30，并保障所述镜头组件10被保持于所述感光芯片20的感光路径，且所述镜头组件10的像面与所述感光芯片20的一成像区域21所在的平面之间的垂直距离较小，且所述镜头组件10的像面与所述感光芯片20的所述成像区域21所在的平面之间的倾斜角度较小，进而在保障所述摄像模组100的成像效果的同时，提高所述摄像模组100的组装效率。优选地，所述镜头组件10的像面与所述感光芯片20的所述成像区域21所在的平面能够重合，来自被拍摄物体的光线通过所述镜头组件30进入所述摄像模组100，然后被所述感光芯片20接收并进行光电转化后形成图像，进而成像于所述感光芯片20的所述成像区域21所在的平面。
进一步地，参照图2A和图2B，在组装所述摄像模组100的一个阶段中，获取所述镜头组件10的一参数信息，并根据所述镜头组件10的参数信息确定所述镜头组件10的像面，进而调整所述镜头组件10与所述感光芯片20之间的高度，以提高所述镜头组件10的像面与所述感光芯片20的所述成像区域21所在平面的重合度。值得一提的是，所述镜头组件10的所述参数信息包括但不限于所述镜头组件10的后焦距、焦点、所述镜头组件10的每一光学镜片11的厚度，所述镜头组件10的整体高度等等，其中所述镜头组件10的后焦距是指靠近所述镜头组件10的一镜筒13的一出光口133的所述光学镜片11靠近所述出光口133的光学表面至所述镜头组件10的后方焦点的距离。
在本发明的一较佳实施例中，扫描设置于所述镜头组件10的所述镜筒13的外侧表面的一标识码130，获取所述镜头组件10的所述参数信息。也就是说，所述标识码130与所述镜头组件10的所述参数信息绑定。例如但不限于，所述标识码130为二维码或是条形码等。进一步地，在组装所述摄像模组100的另一个阶段中，利用激光测高的方法准确地获取所述感光芯片20的所述成像区域21所在的平面的具体位置和所述镜头组件10的表面的位置信息，进而通过快速调整所述镜头组件10的姿态，使得所述镜头组件10的像面和所述感光芯片20的所述成像区域21所在的平面能够重合，从而提高组装所述摄像模组100的效率和准确性。进一步地，在所述摄像模组100的组装过程中，所述摄像模组100的所述镜头组件10的一滤光元件12未被固定于所述感光芯片20的上方，进而避免了所述滤光元件12对所述感光芯片20的遮挡，以使得在利用激光多点测高的方法获取所述感光芯片20的所述成像区域21所在的平面的过程中，经过所述感光芯片20的激光不会受到干扰，进而保障测量的准确性。
举例来说，利用激光多点测高的方法分别获取所述感光芯片20的所述成像区域21所在的平面的具体位置和所述镜头组件10的上表面的具体位置信息，进而得到所述镜头组件10需要调整的角度和方向，并对应地调整所述镜头组件10，以减小所述镜头组件10的像面与所述感光芯片20的所述成像区域21所在的平面之间的倾斜角度，进而保障所述摄像模组100的成像质量。本领域技术人员可以理解，也可以通过获取所述镜头组件10的下表面的具体位置信息或是其他表面的位置信息，参考所述镜头组件10的表面的位置参数和所述感光芯片20的所述成像区域21所在的平面之间的差异来调整所述镜头组件10的姿态。
进一步地，在组装所述摄像模组100的另一个阶段中，贴装所述镜头组件10于所述线路板组件30。具体来说，在所述镜头组件10的下表面和所述线路板组件30的上表面的接触位置施加一胶材，通过一夹持装置调整所述镜头组件10的高度和姿态后，保持所述镜头组件10的像面与所述感光芯片20的所述成像区域21所在的平面之间的垂直距离处于预设范围，且所述镜头组件10的像面与所述感光芯片20的所述成像区域21所在的平面之间的倾斜角度也处于预设范围，待所述胶材固化后，所述镜头组件10和所述感光芯片20被粘接于使得所述摄像模组100成像较佳的位置。本领域技术人员可以理解，固化所述胶材的具体方式不受限制，比如说，可以通过紫外光照射的方式使得所述胶材凝固。并且所述胶材的类型也不受限制，所述胶材可以被实施为紫外固化胶或是热固胶等。
图3和图4A示出了本发明所述摄像模组100的一个较佳实施例，其中所述摄像模组的所述镜头组件10包括至少两光学镜片11和至少一个所述滤光元件12，且在相邻的两个所述光学镜片11之间形成一光学间隙110，其中所述滤光元件12被保持于两个所述光学镜片11之间的所述光学间隙110，，经过所述镜头组件10的所述光学镜片11的光线到达所述滤光元件12，所述滤光元件12对一预定波段的光线进行选择，以减小杂光。所述滤光元件12位于所述感光芯片20的感光路径，以使得来自被拍摄物体的光线在穿过所述滤光元件12后再被所述感光芯片20接收，进而保障所述摄像模组100的获取的图像质量。
值得一提的是，通过将所述滤光元件12设置于两个所述光学镜片11之间的方式，不仅能够避免在组装所述摄像模组100的过程中，所述滤光元件12遮挡所述感光芯片20，而且在将所述镜头组件10贴装于所述线路板组件30后，增加了所述滤光元件12与所述感光芯片20之间的距离，进而减小了所述滤光元件12上的划痕、污点等不良对成像效果的影响，有利于提高了所述摄像模组的成像质量；而且，所述滤光元件12被隐藏于两个所述光学镜片11之间，减小了所述滤光元件12在组装和运输过程中被污染或是被划伤的风险，以利于提高所述摄像模组的成品良率。进一步地，所述摄像模组100的所述滤光元件12被集成于所述镜头组件10，有利于精简丝印工序，以精简组装工序。
所述镜头组件10进一步包括所述镜筒13，其中所述镜筒13具有一装配空间131、连通所述装配空间13的一进光口132和所述出光口133，所述光学间隙110连通所述进光口132和所述出光口133，其中所述光学镜片11和所述滤光元件12可以被实施为自所述进光口132和所述出光口133安装于所述镜筒13的所述装配空间13，并使得所述滤光元件12被保持于两个所述光学镜片11之间的所述光学间隙110内。来自被拍摄物体的光线通过所述镜筒13的所述进光口132进入所述装配空间内12，并在穿过所述光学镜片11和所述滤光元件12后，能够成像于所述感光芯片20。具体来说，所述光学镜片11和所述滤光元件12按照一预设位置被安装于所述镜筒13的所述装配空间21内，所述预设位置可以被实施为但不限于根据光路方向、焦距等条件设置。
值得一提的是，所述镜筒13具有所述标识码130，其中所述标识码130被设置于所述镜筒130的外表面，以便于在组装所述镜头组件10于所述线路板组件30的过程中，获取所述镜头组件10的所述参数信息。也就是说，所述标识码130与所述镜头组件10的所述参数信息绑定。例如但不限于，所述标识码130为二维码或是条形码等。优选地，通过印刷工艺印刷所述标识码于所述镜筒的侧表面。优选地，通过激光雕刻的方式形成所述标识码于所述 镜筒13的侧表面。优选地，所述标识码130被贴装于所述镜筒13的侧表面。本领域技术人员可以理解，形成所述标识码130于所述镜筒13的具体实施方式仅仅作为示意，不能成为对本发明所述摄像模组100及其组装方法的内容和范围的限制，例如，所述标识码130还可以形成于所述光学镜片11、一线路板或是所述摄像模组100的其他组成部件上。优选地，当所述标识码130被设置于所述光学镜片11时，所述标识码130被设置于最靠近所述镜筒13的所述进光口133的所述光学镜片11，以便于所述标识码130更好地被识别。
更值得一提的是，所述镜筒组件10在制造或是组装的过程中，所述镜头组件10的相关光学参数被记录于所述标识码130。比如说，所述光学参数包括但不限于入射角、光轴位置、后焦距、总焦距、曲折度等。另外，所述标识码130除了用于识别作用外，还可以被用于追溯所述镜头组件10的来源。更值得一提的是，设置所述标识码130的具体位置不受限制，并且，可以根据所述标识码130的功能选择所述标识码130的具体形成位置。比如说，在本发明的一实施例中，所述标识码130被设置于所述镜筒组件10的所述镜筒13，在组装时，藉由所述标识码130能够获取所述镜头组件10的所述光学参数；在本发明的另一实施例中，可以藉由被设置于所述镜头组件10的所述滤光元件12或是其他区域的所述标识码130追溯所述镜头组件10的来源，以利于更好地管控所述镜头组件10。
本领域技术人员应该理解的是，所述标识码130的具体位置仅仅作为示意，不能成为对本发明所述摄像模组100和其镜头组件10的内容和范围的限制。比如说，在本发明其他的实施例中，所述摄像模组的所述感光芯片20、所述线路板组件、所述光学镜片11以及其他部件都被设置所述标识码130，并分别记录对应的参数信息，从而，在组装时，仅需通过对每个所述标识码130进行识别，就能够获得组装所需的各个参数信息，以利于简化组装工艺，从而降低了组装工艺难度。
值得一说的是，由于所述标识码130记录所述镜头组件10的参数，故在组装时，可根据所述镜头组件10的参数去挑选或/和匹配相对应的感光芯片，一方面可降低组装难度，另一方面也可以确保所述模组的质量或精度；即，不同的所述感光芯片20的参数不同，所述镜头组件10的参数也不同，但是两者在组装时存在一个调整范围，例如为了光轴重合需要进行调整，当所述感光芯片20和所述镜头组件10相匹配时，该调整范围可管控至可控范围，可降低组装难度，提高组装效率；同时由于所述感光芯片20和所述镜头组件10匹配，使得在不开图组装情况下，良品率进一步得以保证。
