相关申请的交叉引用
本申请要求于2018年10月24日递交于中国国家知识产权局(CNIPA)的、申请号为201811242242.6、发明名称为“夹持装置、夹持方法及光学镜头、摄像模组的组装方法”的中国发明专利申请的优先权和权益,该中国发明专利申请通过引用整体并入本文。
技术领域
本申请涉及光学成像技术领域,具体地,本申请涉及用于光学致动器组件的夹持装置和夹持方法,以及涉及光学镜头和摄像模组的组装方法。
背景技术
随着移动电子设备的普及,移动电子设备中用于帮助使用者获取影像(例如视频或者图像)的摄像模组的相关技术得到了迅猛的发展和进步。近年来,摄像模组在诸如医疗、安防、工业生产等诸多的领域都得到了广泛的应用。
为了满足越来越广泛的市场需求,高像素、小尺寸、大光圈是现有摄像模组不可逆转的发展趋势。然而,要在同一摄像模组实现高像素、小尺寸、大光圈三个方面的需求是有很大难度的。一方面,手机的紧凑型发展和手机屏占比的增加,让手机内部能够用于前置摄像模组的空间越来越小;而另一方面,市场对摄像模组的成像质量的要求变的越来越高。
在紧凑型摄像模组(例如用于手机的摄像模组)领域,镜头是摄像模组的重要部件,直接影响摄像模组的成像品质。在多群组镜头中,镜头部件之间通过主动校准并使用胶材连接,从而形成一个完整的光学系统。对自动调焦摄像头模组进行组装时,需要夹具夹持马达进行 主动校准,在主动校准过程中,镜头的稳定性影响成像质量。在分体式镜头的模组组装过程中,镜头分为多个镜头部件,其中下镜头部件预先和马达组装为光学致动器组件,然后对各镜头部件、光学致动器组件及感光组件进行主动校准,主动校准完成后对上述部件以及组件进行粘结固定。
目前,在主动校准及粘结过程中夹具只对马达进行夹持,但是下镜头部件与马达之间会产生晃动,从而影响主动校准的效果。另外,主动校准完成后需对下镜头部件进行画胶操作,以将第一镜头部件和第二镜头部件进行固定。画胶过程及固化过程中,下镜头部件由于不是直接由夹具进行夹持,所以会产生位置偏移,进而最终影响光学镜头及摄像模组的品质。
本申请提供了一种光学致动器组件的夹持方法,从而使下镜头部件和马达壳体的相对位置保持不变,使得在主动校准和粘结过程中下镜头部件和马达壳体的位置保持固定,进而保证光学镜头及摄像模组的成像质量。

图10B示出了本申请另一个实施例的主动校准中的旋转调节。在该实施例中,相对位置调整除了具有图10A的三个自由度外,还增加了旋转自由度,即r方向的调节。本实施例中,r方向的调节是在所述调整平面P内的旋转,即围绕垂直于所述调整平面P的轴线的旋转。

上述x、y、z、r、v、w六个自由度的调节均可能影响到所述光学系的成像品质(例如影响到解像力的大小)。在本申请的其它实施例中,相对位置调节方式可以是仅调节上述六个自由度中的任一项,也可以其中任两项或者更多项的组合。
进一步地,在一个实施例中,主动校准步骤中,所述移动还包括在所述调整平面上的平移,即x、y方向上的运动。
进一步地,在一个实施例中,所述主动校准还包括:根据所述光学系统的实测解像力,调节并确定所述第一镜头部件100的轴线相对于所述第二镜头部件200的轴线的夹角,即w、v方向上的调节。所组装的光学镜头或摄像模组中,所述第一镜头部件100的轴线与所述 第二镜头部件200的轴线之间可以具有不为零的夹角。
进一步地,在一个实施例中,所述主动校准还包括:沿着垂直于所述调整平面的方向移动所述第一镜头部件100(即z方向上的调节),根据所述光学系统的实测解像力,确定所述第一镜头部件100与所述第二镜头部件200之间的在垂直于所述调整平面的方向上的相对位置。
进一步地,在一个实施例中,所述预定位步骤中,使所述第一镜头部件100的底面和所述第二镜头部件200的顶面之间具有间隙。
在一个实施例中,主动校准步骤中,可以固定第二镜头部件200,通过夹具夹持第一镜头部件100,在与夹具连接的六轴运动机构的带动下,移动第一镜头部件100,从而实现第一镜头部件100和第二镜头部件200之间的上述六个自由度下的相对移动。其中,夹具可以承靠于或部分承靠于第一镜头部件100的侧面,从而将第一镜头部件100夹起。
在上述实施方式中,作为示例,光学镜头被描述为包括第一镜头部件和第二镜头部件。然而,光学镜头中的镜头部件的数目不受特定限制,即,镜头部件的数目不限于两个,根据具体的设计需要,镜头部件的数目可为三个或四个等。
以上描述仅为本申请的较佳实施方式以及对所运用技术原理的说明。本领域技术人员应当理解,本申请中所涉及的发明范围,并不限于上述技术特征的特定组合而成的技术方案,同时也应涵盖在不脱离所述发明构思的情况下,由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
