技术领域

背景技术
随着移动电子设备的普及,被应用于移动电子设备的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,并且在近年来,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。
镜头是摄像模组的一个重要部件,直接影响摄像模组的成像品质。在多群组镜头中,镜头部件之间使用胶水连接,因此往往需要对镜头模组进行烘烤以使胶水完全固化从而实现连接,此时上下镜头部件之间的空气会产生膨胀,气体膨胀会对上下镜头部件进行冲击,从而改变镜头部件的光学元件的相对位置,造成光学能力的下降。因此需要在镜头模组中增加逃气孔设计来降低烘烤给镜头带来的不利影响。逃气孔可以通过在镜筒设置通孔逃气或通过画带缺口的胶水逃气,但逃气孔的增设会增加灰尘和脏污对镜头的不利影响。
因此,如何避免逃气孔给镜头带来灰尘和脏污的同时,降低烘烤给镜头模组带来不利影响是本领域需要解决的问题。

需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
为了便于理解,以下的描述中以包括上下两个镜头的多群组镜头为例对本申请的多群组镜头进行了描述,但是应当理解,本申请的多群组镜头不限于仅具有上下两个镜头,而是也可以具有多于两个镜头。
图1示出了根据本申请一个实施方式的多群组镜头的示意性侧视图。如图1所示,根据本申请的多群组镜头100可包括第一镜头110和第二镜头120,其中,第一镜头110包括第一镜头框架111和至少一透镜112,第二镜头120包括第二镜头框架121和至少一透镜122。第一镜头110和第二镜头120之间使用第一胶水130连接,并在涂覆了第一胶水130后进行UV照射、烘烤,以使胶水完全固化从而实现第一镜头110和第二镜头120之间的连接。
图2示出了图1所示多群组镜头在逃气孔未填充时的沿A-A’线的截面的俯视图。如图2所示,涂覆在第一镜头110和第二镜头120之间的第一胶水130可涂覆为呈C形,由此具有可用作逃气孔的开口140。应当理解,尽管图2示出的第一胶水呈C形涂覆,并且具有一个开口,但是,第一胶水也可以以任意其他适当的形状涂覆,并且可以具有一个或多个作为逃气孔的开口。
图3示出了图1所示的多群组镜头在逃气孔被填充后的沿A-A’线的截面的俯视图。如图3所示,图2示出的开口140用第二胶水150 填充。根据本申请,第二胶水150是在需要烘烤的全部步骤已经完成且第一胶水已经完全固化的情况下执行。第二胶水150是无需烘烤即可完全固化的胶水,例如,UV胶、湿气胶、可见光固化胶等。
图4示出了图3所示的多群组镜头的示意性侧视图。可以看到,在第一镜头110和第二镜头120之间,第二胶水150填充了第一胶水130中的开口140,从而将开口140形成的逃气孔密封。
在以上示例性描述的实施方式中,逃气孔由涂覆在第一镜头和第二镜头之间的胶水的开口或缺口而形成。作为一种选择,逃气孔也可以是与涂覆在第一镜头和第二镜头之间的胶水相关联的其他孔结构。例如,逃气孔可以是多群组镜头的组件中供膨胀的气体排出的通孔。通过使用无需烘烤即可完全固化的第二胶水密封逃气孔,防止灰尘和脏污进入而对镜头模组带来不利的影响。
图1至图4示出了多群组镜头,即,分体式镜头。分体式镜头独立于具有感光元件和马达等部件的摄像模组生产,并且不与摄像模组一起主动校准。对于分体式镜头,在该镜头与感光部件、马达部件等等组成FF定焦模组或AF可调焦模组后,并在模组涂覆的胶水完全固化后,在最后才使用例如UV胶、湿气胶、可见光固化胶等无需烘烤即可完全固化的第二胶水进行补胶。通过使用第二胶水将逃气孔封住,避免灰尘和脏污从逃气孔进入。根据本申请的实施方式,优选地,所有需要烘烤的步骤都留在逃气孔密封前。
根据本申请的实施方式,还提供了一种多群组镜头摄像模组,其中至少一镜头部件先与马达连接,其他镜头部件之后附接并与感光组件一起主动校准。例如,多群组镜头中的第二镜头首先连接于马达,然后将第一镜头安装于已经与马达固定连接的第二镜头。例如,对于有螺纹马达,可以将第二镜头部件旋进马达,定高后,使用UV胶点在镜头和马达载体之间,从而在第二镜头和马达载体之间点胶固定。对于无螺纹马达,第二镜头与马达载体之间可通过胶水定高连接。应当理解,第二镜头与马达载体之间的连接方式并不限于此。
图5示出了根据本申请一个实施方式的多群组镜头摄像模组的示意性侧视图。如图5所示,摄像模组200可包括第一镜头210、第二 镜头220和马达260,其中,第一镜头210包括第一镜头框架211和至少一透镜212,第二镜头220包括第二镜头框架221和至少一透镜222,第二镜头220与马达260定高连接并通过胶水270固定。第二镜头220与马达260定高连接形成的组件也可称为镜头马达组件。在将第一镜头210、定高连接的第二镜头220和马达260、以及成像元件(未示出)沿光轴预定位后,通过主动校准的方法调整各部件之间的相对位置,并布设粘合剂并固化粘合剂以固定模组。其中,布设粘合剂的时间可以在预定位之前。例如,第一镜头210和第二镜头220之间可使用第一胶水230连接,并在涂覆了第一胶水230后进行UV照射、烘烤,以使第一胶水230完全固化从而实现第一镜头210和第二镜头220之间的连接。
在上述的主动校准、涂覆胶水、烘烤和固化都完成后,在最后进行补胶,利用UV胶、湿气胶、可见光固化胶等无需烘烤即可完全固化的第二胶水250,将在第一胶水230中形成的逃气孔封住,避免灰尘和脏污从逃气孔进入。应当理解,使用第二胶水250密封逃气孔的步骤应当在所有需要烘烤的步骤之后,从而避免在密封后由于烘烤而发生形变。
在图5中,点胶间隙(即,第一镜头210与第二镜头220之间的间隙)高于马达260的上表面,或者说,第二镜头220的上表面高于马达260的上表面。在这种情况下,可直接从侧面在第一镜头210和第二镜头220之间使用第二胶水250点胶,将裸露的逃气孔封住。
图6示出了根据本申请一个实施方式的多群组镜头摄像模组的示意性侧视图。在图6中,点胶间隙(即,第一镜头210与第二镜头220之间的间隙)低于马达260的上表面,或者说,第二镜头220的上表面低于马达260的上表面。在这种情况下,无法直接从侧面在第一镜头210和第二镜头220之间点胶。因此,可以通过从第一镜头210与马达260之间的间隙点胶,使第二胶水250将逃气孔240封住。
图7示出了图6所示的摄像模组在逃气孔被填充后的示意性侧视图。如图7所示,第二胶水250沿第一镜头210与马达260之间的缝隙涂覆固化,由此封住了第一胶水230中形成的逃气孔240。
可选地,在补胶时可以沿镜头周围涂覆一圈第二胶水,而不仅仅是仅封住逃气孔,从而在将逃气孔封住的同时,进一步提高镜头的可靠性。如图所示,可在第一镜头210和马达260之间的不与逃气孔240对应的位置处也涂覆第二胶水,以加强第一镜头210与马达260之间的结合强度。例如,可以在第一镜头210和马达260之间涂覆一整圈第二胶水,以加强第一镜头210与马达260之间的结合强度。
图8示出了根据本申请一个实施方式用于制造多群组镜头的方法300的示意性流程图。
如图8所示,在步骤S301,使用第一胶水将用于多群组镜头的第一镜头和第二镜头相互连接。第一胶水是在镜头模组的制作中通常使用的胶水,需要在后续的步骤中通过烘烤而固化。在步骤S302,在第一胶水中提供逃气孔。例如,逃气孔可以是涂覆在第一镜头和第二镜头之间的胶水的缺口而形成。可选地,逃气孔也可以由多群组镜头的组件中供膨胀的气体排出的通孔而形成。逃气孔的设置用于在后续烘烤步骤中使膨胀的空气溢出,而避免导致镜头模组产生不利的形变。在步骤S303,通过烘烤固化第一镜头和第二镜头之间的第一胶水。如上所述,在第一胶水的烘烤过程中,膨胀的空气从逃气孔溢出。在步骤S304,在第一胶水完全固化之后,使用无需烘烤即可完全固化的第二胶水对逃气孔进行填充,从而将逃气孔密封。由此,防止了灰尘和脏污进入逃气孔而对镜头模组带来不利的影响。
以上示例性方法中仅描述了第一镜头和第二镜头之间利用胶水连接并通过烘烤使该胶水固化,应当理解,根据本申请的多群组镜头和多群组镜头摄像模组中还可具有其他需要使用胶水连接并通过烘烤固化的部件,在这种情况下,使用第二胶水对逃气孔的填充和密封应当在所有的烘烤步骤完成之后执行。
如上文参照图5至图7所述,根据本申请实施方式的用于制造多群组镜头摄像模组的方法与用于制造多群组镜头的方法类似,其区别在于,用于制造多群组镜头摄像模组的方法还可包括在使用第一胶水连接第一镜头和第二镜头的步骤之前,将第二镜头定高连接于马达。在定高连接于马达的第二镜头的上表面高于马达的上表面时,可直接 从第一镜头和第二镜头之间的侧面使用第二胶水密封逃气孔。在定高连接于马达的第二镜头的上表面低于马达的上表面时,可从第一镜头与马达的马达载体之间的间隙使用第二胶水密封逃气孔。
本申请中所述的主动校准可以在多个自由度上对各镜头部件相对位置进行调整。主动校准指的是根据光学系统的实测解像力,控制一个镜头部件相对于另一镜头部件进行调整来校准整个光学系统,使得各个镜头部件的轴线调整一致,进而使光学系统的实测解像力达到标准。其中,镜头部件的轴线指的是镜头部件内所有镜片所组成的光学系统的光轴。
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,本申请中所涉及的保护范围,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本申请构思的情况下,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。
