Description

摄像模组、带标记的镜头及其制造方法以及大广角摄像模组的组装方法 技术领域
本发明涉及一摄像模组,尤其涉及一摄像模组、带标记的镜头及其制造方法以及大广角摄像模组的组装方法。
背景技术
随着移动电子设备的普及,摄像装置成为电子终端设备中必不可少的一部分,用于满足使用者对拍摄影像的需求。阵列式摄像模组通常包含有至少两个摄像模组,根据不同的拍照需求进行不同功能的摄像模组的组合,实现在变焦拍摄、大视场拍摄等方面比单镜头摄像有更优秀的表现,成为当下及未来的热门应用。
目前,阵列式摄像模组通常包含有长焦摄像模组、广角摄像模组、普通模组等,比如常见的双摄模组采用长焦模组与广角模组组成。单个电子终端上配备阵列摄像模组,摄像模组数量的增加和新功能摄像模组的加入,对摄像模组的生产工艺、生产效率和组装要求提出了更高的要求。
由于大广角摄像模组的视场角大,由于光线的倾斜度大引起的场曲畸变较大,比如130°的视场角的镜头,畸变大于10%。在利用现有棋盘式的标板拍照测试时,广角摄像模组在测试解像力时大畸变引起常规CTF标板四角解像力难以测试,即广角摄像模组拍摄的图像受畸变影响外围测试直线弯曲严重。在利用现有刃边处理的算法进行计算时,误差大,广角摄像模组的整体解像能力不良,通常采用软件来进行畸变校正。一方面,随着广角摄像模组的视场角越来越大,而软件可调整的畸变范围有限,难以满足超过110°的视场角产生的畸变校正。另一方面,软件畸变校正在调整区域会存在损失像素的问题,软件校正需要处理的图像数据量非常大,所需要的硬件要求也非常高。
为解决广角摄像模组的畸变问题,从光学系统的本身改进出发,采用自由曲面光学镜片来替换对镜头中的其中至少一个普通光学镜片,利用自由曲面的设计自由度来进行光学系统的光路设计,减少大广角带来的畸变影响,以便提高光学系统的技术参数。由于自由曲面光学镜片为非旋转对称体,因此在自由曲面光学镜片被安装时存在较大的不确定性,特别是在摄像模组的组装过程中需要将自由曲面光学镜片形成的有效成像区域对应到感光芯片的成像区域。带有自由曲面光学镜片的镜头在组装时很难观察到自由曲面的有效成像区域方向,从而给组装带来难度。摄像模组的镜头组件再被组装过程中,由于自由曲面光学镜片的存在,不仅需要在平面方向的移动和倾斜,还需要根据有效成像区域与所述感光芯片的成像区域对应,因而需要通过旋转的方式进行调整。现有技术的带有自由曲面光学镜片的镜头的组装速度受限于自由曲面光学镜片的位置调整,难以提高组装速度。
另一方面,对于能够自动对焦的摄像模组,即带有马达的摄像模组,在现有的普通摄像模组的组装过程中,马达先与镜头进行定高锁附,在主动对焦过程中,设备夹持马达与镜头整体,与感光组件进行调整。而当设置有自由曲面光学镜片的镜头仍按照上述方式进行组装时,在旋转调整后,容易导致马达外壳与线路板错位,从而造成摄像模组的外观不良。

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。
参照本发明说明书附图之图1至图6,依照本发明第一较佳实施例的一摄像模组在接下来的描述中被阐明。所述摄像模组包括一镜头10、一感光组件20以及一镜头固定装置30,其中所述镜头10被固定地设置于所述镜头固定装置30,所述感光组件20在通电情况下由所述镜头固定装置30基于所述感光组件20的光学成像性能将所述镜头10固定于所述感光组件20。所述镜头10具有标识功能,其中所述镜头10基于所述镜头10的标识位置被定向地设置于所述镜头固定装置30,通过调整所述镜头固定装置30位置的方式调整所述镜头10与所述感光组件20的相对位置。
所述镜头10校正投射到所述感光组件20所述摄像模组视场范围内的成像光线产生的畸变,所述镜头10在对应于所述感光组件20的位置处形成一成像面101,其中所述成像面101的形状与所述感光组件20的成像区域相适应,以通过所述镜头10校正的方式修正所述摄像模组的场曲畸变。换言之,所述镜头10在被安装时,所述镜头10被以所述成像面101形状适配于所述感光组件20的成像区域形状的方式由所述镜头固定装置30固定于所述感光组件20。
如图2A所示,所述镜头10包括一镜筒11、至少一第一镜片单元12、至少一第二镜片 单元13以及至少一标识元件14,其中所述至少一第一镜片单元12和所述至少第二镜片单元13被依次叠置于所述镜筒11,由所述镜筒11固定所述第一镜片单元12和所述第二镜片单元13。所述标识元件14被设置于所述镜筒11,由所述标识元件14标识出所述镜头10的所述成像面101的位置。通过视觉识别所述标识元件14的位置,定向地固定所述镜头10于所述镜头固定装置30,即根据所述标识元件14的位置固定所述镜头10的所述镜筒11于所述镜头固定装置30。当所述镜头10被固定于所述镜头固定装置30后,所述标识元件14位于所述镜头固定装置30的特定位置处,以便通过视觉识别所述标识元件14调整所述镜头固定装置30与所述感光组件20的相对位置。
所述感光组件20包括一线路板21、一感光元件22、一镜座23以及至少一滤光片24,其中所述感光元件22被可导通地设置于所述线路板21,其中所述镜座23被设置于所述线路板21,所述滤光片24被贴附于所述镜座23。所述镜头固定装置30根据所述标识元件14的位置固定地设置于所述感光组件20的所述镜座23。所述感光组件20的所述感光元件22具有一感光成像区221和环绕于所述感光成像区211的一非感光成像区222,通过调整所述镜头固定装置30与所述感光组件20的相对位置,使得所述镜头10形成的所述成像面101的形状与所述感光成像区221的形状相适应。
值得一提的是,所述镜头10将所述成像面101形成于所述感光元件22的上表面,其中所述成像面101的尺寸稍大于所述感光元件22的所述感光成像区221的尺寸,以便充分利用所述感光元件22以及预留一定的调整余量。
本领域技术人员可以理解的是,所述镜头10的所述第一镜片单元12的至少一表面为自由曲面,即所述第一镜片单元12为非旋转对称的镜片。因此,由所述第一镜片单元12形成的所述成像面101为非圆形区域,即所述镜头10修正所述摄像模组的场曲畸变,而入射到所述感光元件22上表面的区域为非旋转对称的形状。由于所述镜头10的所述镜筒11为旋转对称体,当所述镜头10在被转动时,所述镜头10形成于所述感光元件22的所述成像面101随所述镜头10的转动而转动。
优选地,在本发明的该优选实施例中,所述镜头10形成的所述成像面101为适配于所述感光元件22形状的矩形面,可以理解的是,本领域技术人员可以理解的是,所述镜头10的所述成像面101的形状与所述镜头10的所述第一镜片单元12的光学特性有关,即所述镜头10形成的所述成像面101在此仅仅作为示例性的,而非限制。因此,在本发明的其他实施例中,所述镜头10形成的所述成像面101还可被实施为其他形状。
当所述镜头固定装置30与所述感光组件20被调试以固定时,通过视觉识别的所述标识元件14的位置识别出所述成像面101与所述感光元件22的感光成像区域221相对位置,进而调整所述镜头固定装置30或调整所述感光组件20,以使得所述成像面101适配于所述感光元件22的所述感光成像区221。
具体而言,在所述摄像模组组装的过程中,所述感光组件20被点亮,其中所述感光组件20被固定,调整和固定所述镜头固定装置30相对于所述感光组件20位置;或者所述镜头固定装置30被固定,调整和固定所述感光组件20相对于所述镜头固定装置30的位置。组装设备视觉识别所述标识元件14,根据所述标识元件14的位置确定所述镜头10形成的所述成像面101位置和形状。在所述感光组件20被点亮的状态下,基于所述标识元件14 的位置,调整所述感光组件20和所述镜头固定装置30的相对位置,以使得所述镜头10形成的所述成像面101覆盖所述感光元件22的所述感光成像区221。
值得一提的是,由于所述摄像模组的所述镜头10的所述第一镜片单元12为非旋转对称体。因此,在调试过程中,需要对所述镜头固定装置30或所述感光组件20的shift和title,即在X轴和Y轴方向上的平移,Z轴方向上的倾斜,以使得所述镜头10的光轴垂直于所述感光元件22,所述镜头10的光心处于所述感光成像区221的中心位置。此外,在主动对焦过程中还需要考虑rotation,即要使得所述镜头10形成的所述成像面101与所述感光元件22的所述感光成像区221形状相适应,由组装设备对所述感光组件20或所述镜头固定装置30调整,以保障所述镜头10形成的所述成像面101覆盖所述感光元件22的所述感光成像区221。
当所述镜头10形成的所述成像面101为矩形时,通过调试以使得所述成像面101的长边与所述感光成像区221的长边对应,所述成像面101的短边与所述感光成像区221的短边对应。优选地,所述镜头10基于可视觉识别的所述标识元件14被定向地固定于所述镜头固定装置30,并且当所述镜头固定装置30与所述感光组件20调整和安装时,可使得所述镜头10形成的所述成像面101覆盖所述感光元件22的所述感光成像区221。
如图2B所示,根据本发明的另一方面,本发明的所述摄像模组还可以被实施为能够自动对焦的摄像模组,即带有马达的摄像模组。相应地,所述摄像模组包括一镜头10、一感光组件20、至少一马达40和一马达外壳50,其中所述镜头10被可驱动地连接于所述马达40,由所述马达40基于所述马达外壳50驱动所述镜头10的移动,以调整所述镜头10的焦点位置。
所述镜头10被所述马达40定高锁附于所述马达外壳50,由所述马达外壳50固定所述镜头10于所述感光组件20。在所述镜头10被固定于所述马达外壳50时,所述镜头10基于所述标识元件14的位置被所述马达40定向地设置于所述马达外壳。当所述镜头10被定高锁附于所述马达外壳50后,由所述马达外壳50基于所述标识元件14的位置被调整而固定于所述感光组件20时,所述镜头10形成的所述成像面101覆盖所述感光元件22的所述感光成像区221,并且所述马达外壳50适应于所述感光组件20。换言之,当所述成像面101覆盖所述感光成像区221时,所述马达外壳50固定于所述感光组件20时,其中所述马达外壳50被固定的位置适配于所述感光组件20,避免所述马达外壳50与所述感光组件20的所述线路板21错位,而造成所述摄像模组的外观不良。
如图3至图6示出了本发明所述摄像模组的所述镜头10的一种可选实施方式。所述镜筒11包括一镜筒主体111和形成于所述镜筒主体111的一镜片安装腔112,其中所述第二镜片单元13和所述第一镜片单元12被所述镜筒主体111固定于所述镜片安装腔112。所述标识元件14被设置于所述镜筒111的所述镜筒主体111,通过视觉识别所述标识元件14位置的方式,确定所述镜头10形成的所述成像面101大致的位置和形状。
可以理解的是,所述标识元件14被一体地成型于所述镜筒主体111,其中所述第一镜片单元12和所述第二镜片单元13基于所述标识元件14的位置被固定地安装于所述镜片安装腔112,以便由所述标识元件14的位置确定出所述镜头10形成的所述成像面101大致的位置和形状。本领域技术人员很容易想到的是,所述第一镜片单元12和所述第二镜片单元 13被安装于所述镜筒11的所述镜片安装腔112后,基于所述镜头10形成的所述成像面101设置所述标识元件14于所述镜筒主体111,以便基于视觉识别出的所述标识元件14确定出所述镜头10形成的所述成像面101大致的位置和形状。
所述镜筒11的所述镜筒主体111进一步包括一镜筒上端部1111和自所述镜筒上端部1111一体地向下延伸的一镜筒下端部1112,其中所述镜筒上端部1111界定所述镜筒11的一上端开口1113,所述镜筒下端部1112界定所述镜筒11的一下端开口1114,其中所述镜片安装腔112连通所述上端开口1113和所述下端开口1114。
在本发明的该优选实施例中,所述标识元件14被设置于所述镜筒主体111的所述镜筒上端部1111,以便组装设备在所述镜筒11的上端视觉识别所述标识元件14的位置,以识别出所述镜头10形成的所述成像面101的位置和形状。优选地,在本发明的该优选实施例中,所述标识元件14被实施为一凸起,其中所述标识元件14被一体地成型于所述镜筒主体111的所述镜筒上端部1111。
所述第一镜片单元12包括一有效径部121和一结构部122,其中所述有效径部121位于所述结构部122的内侧,其中外界光线经由所述有效径部121到达所述成像面101,外界光线经由所述结构部122达到所述成像面101的外侧。简言之,所述第一镜片单元12的所述有效径部121对应于所述镜头10形成的所述成像面101的区域位置。相应地,所述标识元件14被用于标识所述第一镜片单元12的所述有效径部121的位置和形状。示例性的,在本发明的该优选实施例中,所述第一镜片单元12的所述有效径部121沿光轴方向的投影为矩形的形状。
优选地,所述标识元件14被设置于所述镜筒上端部1111,其中至少一所述标识元件14对应于所述第一镜片单元12的所述有效径121长边或短边的中轴面与所述镜筒111交点的位置。本领域技术人员很容易想到的是,所述标识元件14被设置的位置和数量在此仅仅作为示例性的,而非限制。也就是说,视觉系统基于视觉识别所述标识元件14相对于所述镜筒主体111的位置,以确定所述第一镜片单元12的所述有效径部121,从而确定出所述成像面101的位置和形状。本领域技术人员很容易想到的是,可以通过两个或两个以上的所述标识元件14被布置在所述镜筒主体111的位置,确定所述第一镜片单元12的所述有效径部121,从而确定出所述成像面101的位置和形状。
所述标识元件14凸出于所述镜筒主体111的所述镜筒上端部1111,其中所述标识元件14的高度在0.1至0.3mm之间。

参照本发明说明书附图之图8和图9A所示,依照本发明另一较佳实施例的一大广角摄像模组的组装方法在接下来的描述中被阐明。所述大广角摄像模组包括一镜头组件8100和一感光组件8200,通过所述组装方法将所述镜头组件8100被固定于所述感光组件8200。在本发明的该优选实施例中,所述镜头组件8100设有标记,在组装过程中,设置于所述镜头组件8100的标记可被组装设备的视觉识别系统识别,并且基于视觉识别的所述标记位置调整所述镜头组件8100和所述感光组件8200的相对位置,以便所述镜头组件8100与所述感光组件8200相匹配,所述感光组件8200能够正常成像。
如图9A示出了本发明所述大广角摄像模组的所述镜头组件8100的一种可选实施方式,所述镜头组件8100包括一镜头810和一镜头固定装置830,其中所述镜头810被固定地设置于所述镜头固定装置830,所述感光组件8200在通电情况下由所述镜头固定装置830基于所述感光组件8200的光学成像性能将所述镜头810固定于所述感光组件8200。所述镜头810具有标识功能,其中所述镜头810基于所述镜头810的标识位置被定向地设置于所述镜头固定装置830,通过调整所述镜头固定装置830位置的方式调整所述镜头810与所述感光组件8200的相对位置。
在本发明的该优选实施例中,所述大广角摄像模组的组装设备识别所述镜头组件8100,和夹持固定视觉识别的所述镜头组件8100,所述组装设备通过调整所述镜头组件8100相对于所述感光组件8200的相对位置,使得所述镜头组件8100的安装位置适配于所述感光组件8200,即所述感光组件8200获得清晰可靠的成像效果。本领域技术人员很容易想到的是,所述大广角摄像模组的组装设备夹持所述镜头组件8100后,可通过调整所述镜头组件200相对于所述镜头组件8100的相对位置,以使得所述感光组件8200适配于所述镜头组件8100。
所述镜头810对投射到所述感光组件8200所述大广角摄像模组视场范围内的成像光线校正对应的畸变,所述镜头810在对应于所述感光组件8200的位置处形成一靶面8101,其中所述靶面8101的形状与所述感光组件8200的成像区域相适应,以通过所述镜头810校正的方式修正所述大广角摄像模组的场曲畸变。换言之,所述镜头810在被安装时,所述镜头810被以其靶面8101形状适配于所述感光组件8200的成像区域形状的方式由所述镜头固定装置830固定所述感光组件8200。
如图9A所示,所述镜头810包括一镜筒811、至少一自由曲面光学镜片812、至少一镜片单元813以及至少一标识元件814,其中所述至少一自由曲面光学镜片812和所述至少镜片单元813被依次叠置于所述镜筒811,由所述镜筒811固定所述自由曲面光学镜片812和所述镜片单元813。所述标识元件814被设置于所述镜筒811,由所述标识元件814标识出所述镜头810的所述靶面8101的位置。通过视觉识别所述标识元件814的位置,定向地固定所述镜头810于所述镜头固定装置830,即根据所述标识元件814的位置固定所述镜头810的所述镜筒811于所述镜头固定装置830。当所述镜头810被固定于所述镜头固定装置830后,所述标识元件814位于所述镜头固定装置830的特定位置处,以便通过视觉识别所 述标识元件814调整所述镜头固定装置830与所述感光组件8200的相对位置。
所述组装设备的一视觉识别系统可识别所述镜头810的所述标识元件814,其中所述视觉识别系统识别所述标识元件814后,由所述组装设备的一夹持固定装置夹持所述镜头810和根据所述标识元件814的位置调整所述镜头810的位置。根据所述标识元件814的位置调整所述镜头810被固定于所述镜头固定装置830的位置,以便所述组装设备夹持所述镜头固定装置830,通过操作所述镜头固定装置830的位置和角度将所述镜头组件8100以适配于所述感光组件8200的方式固定于所述感光组件8200。
所述感光组件8200包括一线路板821、一感光元件822、一镜座823以及至少一滤光片824,其中所述感光元件822被可导通地设置于所述线路板821,其中所述镜座823被设置于所述线路板821,所述滤光片824被贴附于所述镜座823。所述镜头固定装置830根据所述标识元件814的位置固定地设置于所述感光组件8200的所述镜座823。所述感光组件8200的所述感光元件822具有一感光成像区8221和环绕于所述感光成像区8221的一非感光成像区8222,通过调整所述镜头固定装置830与所述感光组件8200的相对位置,使得所述镜头810形成的所述靶面8101的形状与所述感光成像区8221的形状相适应。
值得一提的是,所述镜头810将所述靶面8101形成于所述感光元件822的上表面,其中所述靶面8101的尺寸稍大于所述感光元件822的所述感光成像区8221的尺寸,以便充分利用所述感光元件822以及预留一定的调整余量。
本领域技术人员可以理解的是,所述镜头810的所述自由曲面光学镜片812的至少一表面为自由曲面,即所述自由曲面光学镜片812为非旋转对称的镜片。因此,由所述自由曲面光学镜片812形成的所述靶面8101为非圆形区域,即所述镜头810修正所述大广角摄像模组的场曲畸变,而入射到所述感光元件822上表面的区域为非旋转对称的形状。由于所述镜头810的所述镜筒811为旋转对称体,当所述镜头810在被转动时,所述镜头810形成于所述感光元件822的所述靶面8101随所述镜头810的转动而转动。
优选地,在本发明的该优选实施例中,所述镜头810形成的所述靶面8101为适配于所述感光元件822形状的矩形面,可以理解的是,本领域技术人员可以理解的是,所述镜头810的所述靶面8101的形状与所述镜头810的所述自由曲面光学镜片812的光学特性有关,即所述镜头810形成的所述靶面8101在此仅仅作为示例性的,而非限制。因此,在本发明的其他实施例中,所述镜头810形成的所述靶面8101还可被实施为其他形状。
当所述镜头固定装置830与所述感光组件8200被调试和固定时,通过视觉识别的所述标识元件814的位置识别出所述靶面8101与所述感光元件822的感光成像区8221相对位置,进而调整所述镜头固定装置830或调整所述感光组件8200,以使得所述靶面8101适配于所述感光元件822的所述感光成像区8221。
具体而言,在所述大广角摄像模组组装的过程中,所述感光组件8200被点亮,其中所述感光组件8200被固定,调整和固定所述镜头固定装置830相对于所述感光组件8200位置;或者所述镜头固定装置830被固定,调整和固定所述感光组件8200相对于所述镜头固定装置830的位置。组装设备视觉识别所述标识元件814,根据所述标识元件814的位置确定所述镜头810形成的所述靶面8101位置和形状。在所述感光组件8200被点亮的状态下,基于所述标识元件814的位置,调整所述感光组件8200和所述镜头固定装置830的相对位 置,以使得所述镜头810形成的所述靶面8101覆盖所述感光元件822的所述感光成像区8221。
值得一提的是,由于所述大广角摄像模组的所述镜头810的所述自由曲面光学镜片812为非旋转对称体。因此,在调试过程中,需要对所述镜头固定装置830或所述感光组件8200的shift和title,即在X轴和Y轴方向上的平移,Z轴方向上的倾斜,以使得所述镜头810的光轴垂直于所述感光元件822,所述镜头810的光心处于所述感光成像区8221的中心位置。此外,在主动对焦过程中还需要考虑rotation,即通过旋转的方式调整所述镜头组件8100或所述感光组件8200,以使得所述镜头810形成的所述靶面8101与所述感光元件822的所述感光成像区8221形状相适应,由组装设备对所述感光组件8200或所述镜头固定装置830调整,以保障所述镜头810形成的所述靶面8101覆盖所述感光元件822的所述感光成像区8221。
当所述镜头810形成的所述靶面8101为矩形时,通过调试以使得所述靶面8101的长边与所述感光成像区8221的长边对应,所述靶面8101的短边与所述感光成像区8221的短边对应。优选地,所述镜头810基于可视觉识别的所述标识元件814被定向地固定于所述镜头固定装置830,并且当所述镜头固定装置830与所述感光组件8200调整和安装时,可使得所述镜头810形成的所述靶面8101覆盖所述感光元件822的所述感光成像区8221。

在本发明的该优选实施例中,所述镜头810被所述马达840定高锁附于所述马达外壳850,由所述马达外壳850固定所述镜头810于所述感光组件8200。在所述镜头810被固定于所述马达外壳850时,所述镜头810基于所述标识元件814的位置被所述马达840定向地设置于所述马达外壳850,使得所述镜头810形成的所述靶面8101的方向与所述马达外壳850的方向相适应。当所述镜头810被定高锁附于所述马达外壳850后,由所述马达外壳850基于所述标识元件814的位置被调整而固定于所述感光组件8200时,所述镜头810形成的所述靶面8101覆盖所述感光元件822的所述感光成像区8221,并且所述马达外壳850适应于所述感光组件8200。换言之,当所述靶面8101覆盖所述感光成像区8221时,所述马达外壳850固定于所述感光组件8200时,其中所述马达外壳850被固定的位置适配于所述感光组件8200,避免所述马达外壳850与所述感光组件8200的所述线路板821错位,而造成所述大广角摄像模组的外观不良。
根据视觉识别的所述标识元件814的位置确定出所述靶面8101的位置,以所述靶面8101被形成的方向和所述马达外壳850相适应的方式固定所述镜头810于所述马达840。示例性的,基于所述标识元件814的位置确认所述靶面8101的方向和位置,并且调整所述靶面8101的长边方向平行于所述马达外壳850的一边,利用感光元件822的贴附方向与所述线路板821矩形方向相适应,从而使得经历主动对焦调整后,当所述靶面8101与所述感光元件822的所述感光成像区8221的相适应时,所述马达外壳850与所述线路板821方向 也满足相适应的过程。
详细地讲,所述镜头810被固定于所述马达外壳850时,所述马达外壳850被固定在定高治具,其中所述安装设备的所述视觉识别系统识别所述镜头810的所述标识元件814和所述马达外壳850的外部轮廓。根据识别出的所述标识元件814和所述马达外壳850的外部轮廓确定出所述镜头810的所述镜筒811被固定至所述马达外壳850所需要的旋转调整角度。所述安装设备夹持所述镜头810的所述镜筒811,和根据所述标识元件814的位置调整所述镜筒811的安装位置,使得所述镜头810形成的所述靶面8101的一边(比如长边)与所述马达外壳850的外部轮廓的一边平行,以保证所述镜头810与所述马达840的平行组装。
