如图1所示,本发明一实施例的摄像模组10,应用于智能终端。在一实 施例中,智能终端包括终端本体以及设于终端本体的摄像模组10。在一实施例中,智能终端为智能手机、笔记本电脑、平板电脑、便携电话机、视频电话、数码静物相机、电子书籍阅读器、便携多媒体播放器(PMP)、移动医疗装置、可穿戴式设备等智能终端。
在一实施例中,该摄像模组10包括感光组件10a以及镜头组件10b。镜头组件10b设于感光组件10a的感光路径上,物体侧的光线经过镜头组件10b后到达感光组件,从而实现成像。在一实施例中,镜头组件10b包括镜座以及设于镜座内的多群组镜头。在一实施例中,镜头组件10b包括设置于镜座上的音圈马达,此时摄像模组10为可变焦摄像模组。
多群组镜头包括多个独立的镜头,这样每个镜头内的镜片相对较少,每个独立镜头内的镜片组装误差较小,同时多个镜头总共的镜片数目又很多,从而可以满足高像素镜片的要求。由于镜头中的镜片采用模具加工设计,在镜片两面曲率范围内会使用模仁进行超精密加工,而镜片的外径则是采用一般精密精工,因此会造成镜片面型与外径不同心的问题。在一实施例中,如图2所示,多群组镜头包括第一镜头100以及与第一镜头100连接的第二镜头200。在第一镜头100与第二镜头200组装过程中,第二镜头200能够相对第一镜头100转动,从而使得第二镜头100的光轴能够与第一镜头200的光轴相互接近直至重合(包括近似重合),以缓解由于多群组镜头内镜片的偏心所造成的影像质量不好。另外,由于感光组件10a中电路板不平整、封装胶水收缩等因素的存在,镜头成像场曲较大,摄像模组10的良品率很难被控制和保证,第二镜头200能够沿着多群组镜头的光轴方向相对第一镜头100运动,从而可以改善多群组镜头的场曲,提升摄像模组10的成像品质。需要说明的是,第一镜头100可以理解为像侧镜头,第二镜头200可以理解为物侧镜头,也即第一镜头100相比第二镜头200更靠近感光组件10a。
在一实施例中,请继续参考图2,第一镜头100包括第一镜筒110和设于第一镜筒110内的第一镜片组120,第一镜片组120包括一个或多个第一镜片120a。当第一镜片组120包括多个第一镜片120a时,多个第一镜片120a 沿第一镜头100的光轴方向顺序排布。在一实施例中,第一镜头100包括第一遮光片130以及第一固定环140,第一遮光片130设于第一镜筒110的内壁并位于相邻两个第一镜片120a之间,第一固定环140设于第一镜筒110远离第二镜筒210的一侧并与第一镜片120a连接。其中,第一遮光片130能够约束通过第一镜片120a的光线,以提供预定的光线通路,第一固定环140能够将第一镜片120a固定于第一镜筒110中。需要说明的是,当第一镜片120a通过胶粘的方式固定于第一镜筒110内时,第一遮光片130和第一固定环140可以省略。
第二镜头200包括第二镜筒210和设于第二镜筒210内的第二镜片组220,第二镜片组220包括一个或多个第二镜片220a。当第二镜片组220包括多个第二镜片220a时,多个第二镜片220a沿第二镜头200的光轴方向顺序排布。在一实施例中,第二镜头200包括第二遮光片230以及第二固定环240,第二遮光片230设于第二镜筒210的内壁并位于相邻两个第二镜片220a之间,第二固定环240设于第二镜筒210靠近第一镜筒210的一侧并与第二镜片220a连接。其中,第二遮光片230能够约束通过第二镜片220a的光线,以提供预定的光线通路,第二固定环240能够将第二镜片220a固定于第二镜筒210中。需要说明的,当第二镜片220a通过胶粘的方式固定于第二镜筒210内时,第二遮光片230和第二固定环240可以省略。
第二镜头200与第一镜头100无间隙组装。在一实施例中,如图2和图3所示,第一镜筒110包括第一筒体111以及与第一筒体111连接的承载部112,承载部112开设有与第一筒体111连通的通光孔1121。第二镜筒210包括第二筒体211以及与第二筒体211的外壁连接的搭接部212。搭接部212设于承载部112。在一实施例中,多群组镜头包括粘结层300,粘结层300设于搭接部212与承载部112之间,从而第一镜头100和第二镜头200可以通过粘结层300进行固定。其中,粘结层300所用胶水可以但不限定为UV胶、热固胶、环氧树脂胶、压敏胶、湿气固化胶、光固化胶等等。第二筒体211部分设于通光孔1121内并与承载部112的内壁无间隙贴合。可以理解,在其 他实施例中,如图4所示,第二镜头200中最靠近第一镜头100的第二镜片组220中的第二镜片220a凸出于第二筒体211并与承载部112的内壁无间隙贴合。
在一实施例中,如图5所示,第一镜头100中最靠近第二镜头200的第一镜片组120中的第一镜片120a凸出于第一筒体111并具有配合部121,配合部121包括第一表面1211以及与第一表面1211连接的第二表面1212,其中第一表面1211可以理解为第一镜片120a靠近第二镜头200的端面,第二表面1212可以理解为第一镜片120a的内侧面。搭接部212设于第一表面1211。在一实施例中,多群组镜头包括粘结层300,粘结层300设于搭接部212与第一表面1211之间,从而第一镜头100和第二镜头200可以通过粘结层300进行固定。第二筒体211的外壁与第二表面1212无间隙贴合。可以理解,在其它实施例中,如图6所示,第二镜头200中最靠近第一镜头100的第二镜片组220中的第二镜片220a凸出于第二筒体211并与第二表面1212无间隙贴合。
现有技术摄像模组的光学镜头一般在镜头厂商由多个镜片相互重叠地封装在一起制成,由于镜片本身公差、封装工艺、以及制造工艺的限制,每个镜片的中心轴线会存在一定的偏差。并且,在将镜片通过粘结介质或焊接方式设于镜头内的过程中,粘结介质和焊接物质也会影响每个镜片的位置和倾斜度,导致封装后的光学镜头的中心轴线存在较大的偏差,这必然影响由镜头厂商出厂后的镜头在模组厂商组装得到的摄像模组的成像品质,且由于电路板不平整、封装胶水收缩等因素的存在,镜头场曲较大,摄像模组的良品率很难被控制和保证。
为了提高摄像模组10的成像品质,在组装本发明的摄像模组10时,可采用主动调整(Active Alignment,AA)来确保感光组件10a和镜头组件10b的中心轴线在允许偏差的范围内相对一致。具体地,在组装摄像模组10的过程中,首先将封装完成的感光组件10a和多群组镜头移动至预设高度后,使第一镜头100和第二镜头200发生相对旋转,直至感光组件10a所呈现的影 像的中心与四周质量分布均匀。当感光组件10a所呈现的影像的中心与四周质量分布均匀时,使第一镜头100和第二镜头200沿着光轴方向发生相对运动,以进行多群组镜头的场曲补正。当感光组件10a所呈现的影像中心与四周的MTF(Modulation Transfer Function,调制传递函数)值最高时,在第一镜头100与第二镜头200之间点胶形成上述各实施例的粘结层300,以固定第一镜头100和第二镜头200。然后将上述调芯完成后的多群组镜头安装于镜座内并通过治具组装到相对感光组件10a的预设高度,完成后续点胶固化的流程。
在上述摄像模组10的组装过程中,由于第二镜头200能够相对第一镜头100转动,使得第一镜头100的光轴能够与第二镜头20的光轴重合,从而消除了封装后的光学镜头的中心轴线存在较大偏差的技术问题,也即镜片偏心所造成的影像质量衰退能够通过第一镜头100与第二镜头200的相对运动得到有效缓解,包括上述多群组镜头的摄像模组10的成像品质能够得到有效提升。另外,第一镜头100与第二镜头200之间采用无间隙组装,还可以起到防尘的效果,进一步优化了镜头的成像品质。

在本发明中,除非另有明确的规定和限定,术语“安装”、“相连”、“连 接”、“固定”等术语应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或成一体;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通或两个元件的相互作用关系,除非另有明确的限定。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中,除非另有明确的规定和限定,第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触,或第一和第二特征通过中间媒介间接接触。而且,第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方,或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方,或仅仅表示第一特征水平高度小于第二特征。
在本说明书的描述中,参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中,对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且,描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外,在不相互矛盾的情况下,本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
