在现有技术中,为了提升镜头模组的同轴度和同心度,在装配镜片组时,多个镜片组参照同一基准面进行安装(即以同一基准面作为了定位基准),在一定程度确保了镜头模组的同轴度和同心度。但是这种方式只适用于固定镜片组(即定焦模组),若是镜头模组中存在活动镜片组,在镜头模组的使用中,会通过活动镜片组的移动实现镜头模组的变焦。在活动镜片组移动后,多个活动镜片组之间,以及活动镜片组与固定镜片组之间存在偏心问题(即同轴度和同心度降低),因此如何解决活动镜片组和固定镜片组,或者活动镜片组和活动镜片组之间的偏心问题是目前所面临的一个技术问题。In the prior art, in order to improve the coaxiality and concentricity of the lens module, when assembling the lens group, multiple lens groups are installed with reference to the same reference plane (that is, the same reference plane is used as the positioning reference). Ensure the coaxiality and concentricity of the lens module. However, this method is only applicable to the fixed lens group (ie, the fixed focus module). If there is a movable lens group in the lens module, during the use of the lens module, the zoom of the lens module will be realized by the movement of the movable lens group. After the movable lens group is moved, there are eccentricity problems between multiple movable lens groups and between the movable lens group and the fixed lens group (that is, the coaxiality and concentricity are reduced), so how to solve the movable lens group and the fixed lens group, Or the eccentricity problem between the movable lens group and the movable lens group is a technical problem currently faced.

具体地,镜筒1具有容置空间和围合容置空间的圆筒形本体。镜片组2设置在容置空间内。安装槽10开设在圆筒形本体,安装槽10并贯穿圆筒形本体的外壁和内壁。Specifically, the
在一个具体的实施中,当需要调节镜头模组中一个镜片组2的偏心问题时,在镜筒1上开设一组安装槽10,其中安装槽10的设置位置,与镜片组2的设置位置对应;当需要调整镜头模组中多个镜片组2的偏心问题时,在镜筒1上开设多组安装槽10,其中安装槽10一一分别地与镜片组2对应设置。In a specific implementation, when it is necessary to adjust the eccentricity of a lens group 2 in the lens module, a set of

具体地,调节部31与盲孔23的底表面231存在调节间隙4,当固定部32没有将固定架21和调节部31连接在一起的情况下,镜片组2在径向方向上靠近调节件3运动,调节间隙4会逐渐减小,镜片组2在径向方向上远离调节件3运动,调节间隙4会逐渐增大,通过调整调节间隙4的大小,以调整镜片组2在镜筒1内的设置位置,以解决镜片组2的偏心问题。Specifically, there is an
