本申请提供一种镜头模组10,如图3所示,该镜头模组10包括镜筒100以及收容于镜筒100内的镜片组200,其中,该镜筒能够避免与镜片组200发生干涉,从而能够提高镜片组200的安装良率。
现有镜头模组的结构如图1和图2所示,毛边的形成过程如图5和图6所示,由于剪切第一镜片210会产生毛边216,毛边216会与镜筒100'的顶壁120'产生干涉,从而会影响镜片组200与镜筒100'的组装良率。
本申请为解决上述问题,在本申请一实施例中,如图3和图4所示,该镜筒100包括具有通光孔的顶壁120和自顶壁120弯折延伸的筒壁110,所述顶壁120与所述筒壁110围合形成收容所述镜片组200的腔体;所述顶壁120包括抵接所述镜片组200的抵接面121,所述筒壁110包括靠近所述镜片组200的内壁面111,所述抵接面121与所述内壁面111的连接处开设有向远离所述镜片组200的方向凹陷的避空槽122。
如图3至图6所示,由于顶壁120的抵接面121与筒壁110的内壁面111的连接处开设有避空槽122,且该避空槽122向远离所述镜片组200的方向凹陷,因此,镜片组200装入镜筒100后,即使镜片组200的镜片上存在毛边216,该毛边216也能够进入避空槽122,从而能够避免镜片上的毛边216干涉镜片组200进入镜筒100,因此能够提高镜片组200和镜筒100的组装良率。
此外,由于镜筒100上开设有容纳毛边216的避空槽122,因此还能够避免镜筒100挤压毛边216而导致的镜片变形,因此能够保证采用本申请提供的镜筒100的镜头模组10的成像效果。
在一个实施例中,如图3至图6所示,考虑到切割镜片组200的第一镜片210时,通常是沿第一镜片210的轴向切割镜片,因此第一镜片210的毛边216通常堆积在第一镜片210靠近物侧的上端面上,而第一镜片210的上端面与镜筒100的顶壁120的抵接面121相抵接,因此,本实施例中,避空槽122开设在顶壁120的抵接面121上,如此,避空槽122与毛边216的位置相对应,毛边216能够方便地进入避空槽122中。
然而本申请的设计不限于此,在其他实施例中,避空槽122还可以开设在筒壁110的内壁面111上,这种结构的避空槽122适合毛边216位于镜片周侧面的情形。
在一个实施例中,如图3和图4所示,为了既能够保证镜片组200与镜筒100安装后的稳定性,又能够保证避空槽122具有足够大的体积容纳毛边216,本申请一实施例中,所述避空槽122沿所述镜筒100径向的宽度与所述抵接面121的非避空部分沿所述镜筒100径向的宽度的比值为1:1。如此,避空槽122沿镜筒100径向的长度与抵接面121的非避空部分沿镜筒100径向的长度相等,在这种情况下,抵接面121与镜片具有合适大小的抵接面积121,因此,镜片组200与镜筒100安装后的稳定性较高;与此同时,避空槽122具有足够大的空间,因此能够容纳较大体积的毛边216。
具体地,在本实施例中,所述避空槽122沿所述镜筒100径向的长度和所述抵接面121的非避空部分沿所述镜筒100径向的长度约为100μm-160μm;可以理解地,当毛边216体积较大时,可适应性地增大所述避空槽122沿所述镜筒100径向的长度,当毛边216体积较小时,可适应性地减小所述避空槽122沿所述镜筒100径向的长度,因此所述避空槽122沿所述镜筒100径向的长度和所述抵接面121的非避空部分沿所述镜筒100径向的长度也可以呈差别设置。
在一个实施例中,如图3和图4所示,本申请一实施例中,所述避空槽122沿所述镜筒100轴向的深度h的范围为20μm-30μm。经实验发现,当避空槽122深度h的范围为20μm-30μm时,可以基本满足容纳不同体积尺寸毛边216的需要。
优选地,本实施例中,所述避空槽122的槽壁呈圆滑设置。具体地,所述避空槽122包括远离所述镜片组200的底面1221,所述底面1221与所述抵接面121圆弧连接,由于避空槽122的底面1221与抵接面121圆弧连接,因此避空槽122的槽壁呈圆滑设置,便于避空槽的精准成型。
在本实施例中,如图3所示,所述镜片组200包括第一镜片210。实际上,镜片组200还包括第二镜片220和第三透镜230,在其他实施例中,所述镜片组200还可以包括第四透镜(图未示),也可以还包括第五透镜(图未示),甚至更多个镜片,总之,镜片组200中镜片的数量可根据实际需要而定。
为方便介绍,以镜片组200中镜片的数量为3个为例,也即,镜片组200包括第一镜片210、第二镜片220和第三透镜230。如图3所示,第一镜片210、第二镜片220和第三透镜230由像侧至物侧依次收容于所述镜筒100的腔体内,其中,第一镜片210为最靠近像侧的一个镜片。
在本实施例中,如图5和图6所示,为了减小毛边216的体积,所述第一镜片210具有相对设置的第一物侧面211和第一像侧面212,以及连接所述第一物侧面211和所述第一像侧面212的第一周侧面213;所述第一周侧面213和所述第一物侧面211的连接处开设有削料缺口214,由于削料缺口214能够减小第一镜片210周缘的体积,因此能够减小毛边216的体积,从而能够避免毛边216体积过大,进而能够避免毛边216干涉镜片组200进入镜筒100。
具体地,所述削料缺口214的靠近光轴的一侧为镜片剪切位置,如此,当第一镜片210上存在毛边216时,毛边216会填充至镜片剪切位置处。作为一种优选方式,在所述镜筒100的径向方向上,所述底面1221的靠近光轴的一侧与所述镜片剪切位置的距离a的范围为30μm -40μm,如此,可以保证避空槽122具有足够的空间收容毛边。
在一个实施例中,如图6所示,本申请一实施例中,所述第一周侧面213和所述第一像端面的连接处开设有剪切定位槽215,如此,剪切第一镜片210的边缘时,能够准确地对第一镜片210边缘的剪切位置进行定位,进而能够使得剪下的毛边216的位置相对稳定,从而能够保证毛边216准确地进入避让槽中。
在一个实施例中,如图6所示,考虑到剪切定位槽215的作用是供剪切工具能够位置准确地剪切第一镜片210,为了能够使得剪切形成的毛边216的体积更容易被削料缺口214所弥补,本实施例中,所述剪切定位槽215沿所述镜筒100径向的长度小于所述削料缺口214沿所述镜筒100径向的长度,换句话说,削料缺口214的体积大于剪切定位槽215的体积,因此,沿剪切定位槽215剪切形成的毛边216大部分可以被削料缺口214所弥补,因此,最终形成的毛边216的体积较小,进而能够保证毛边216能够完全容纳在避空槽122中。
本申请还提供一种电子设备1,如图7所示,该电子设备1包括所述镜头模组10,该镜头模组10的具体结构参照上述实施例,由于本申请提供的电子设备1采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果,在此不再一一赘述。在此需要说明的是,所述电子设备1可以为手机、平板电脑、笔记本电脑等。
以上所述的仅是本申请的实施方式,在此应当指出,对于本领域的普通技术人员来说,在不脱离本申请创造构思的前提下,还可以做出改进,但这些均属于本申请的保护范围。
