技术领域Technical field

本发明涉及光学技术和摄影技术领域，具体地说，本发明涉及分体式变焦镜头、摄像模组及相应的组装方法。The present invention relates to the fields of optical technology and photography technology. Specifically, the present invention relates to a split zoom lens, a camera module and a corresponding assembly method.

背景技术Background technique

随着消费水准的提高，市场对于手机摄像功能的要求也越来越高，例如人们往往期待手机摄像模组具有变焦能力。然而，市场对智能手机等消费电子终端设备的尺寸要求也极其严苛，尤其是对于手机前置摄像模组(即前摄)来说，其径向尺寸(指垂直于摄像模组光轴的方向)和轴向尺寸(指摄像模组光轴的方向，即手机厚度方向)均受到严格限制，往往难以容纳带有音圈马达的摄像模组。所以，一般仅采用一颗定焦摄像模组作为手机的前置摄像模组，而定焦摄像模组在拍摄过程中难以实现焦距调节，导致其拍摄效果存在缺憾。As the consumption level increases, the market has higher and higher requirements for the camera function of mobile phones. For example, people often expect mobile phone camera modules to have zoom capabilities. However, the market has extremely stringent requirements on the size of consumer electronic terminal devices such as smart phones, especially for the front camera module of the mobile phone (that is, the front camera), the radial size (referring to the vertical to the optical axis of the camera module) Direction) and axial size (referring to the direction of the optical axis of the camera module, that is, the thickness direction of the mobile phone) are strictly limited, and it is often difficult to accommodate a camera module with a voice coil motor. Therefore, generally only one fixed-focus camera module is used as the front camera module of a mobile phone, and it is difficult for the fixed-focus camera module to adjust the focal length during the shooting process, which leads to the shortcomings in the shooting effect.

另一方面，随着消费者对手机屏占比提升的要求越来越高，打孔屏也成为一种手机屏幕设计趋势。“打孔屏”即通过取消屏幕中部分影响镜头接收光线的结构，形成一可以透过可见光的孔，在该孔对应的位置设置一摄像模组，从而实现手机前置拍摄的同时，尽可能地提升屏占比。但目前的摄像模组的头部尺寸均在3mm以上，摄像模组的头部放入孔中会使得屏幕开孔的尺寸要够大，而将摄像模组置于屏幕之后，考虑到摄像模组视场角的需求，屏幕开孔的侧壁不能影响摄像模组采集光线，因此同样的开孔要做的相对较大，其至少在4.5mm以上。这种较大的开孔会导致屏幕的显示效果不佳，影响到屏幕的使用体验。因此需要一种能够减小屏幕开孔的前置摄像模组(即前摄)设计方案。On the other hand, as consumers are increasingly demanding an increase in the proportion of mobile phone screens, perforated screens have also become a mobile phone screen design trend. "Punch screen" is to form a hole that can transmit visible light by canceling part of the structure of the screen that affects the light received by the lens, and set a camera module at the position corresponding to the hole, so as to realize the front-facing shooting of the mobile phone, as much as possible Increase the screen-to-body ratio. However, the head size of the current camera module is above 3mm. Putting the head of the camera module into the hole will make the size of the screen opening large enough. When the camera module is placed behind the screen, considering the camera module According to the requirements of the viewing angle, the side wall of the screen opening cannot affect the light collected by the camera module. Therefore, the same opening needs to be relatively large, which is at least 4.5mm or more. Such a large opening will cause the display effect of the screen to be poor, and affect the user experience of the screen. Therefore, there is a need for a front camera module (ie, front camera) design solution that can reduce screen openings.

最后，变焦、防抖、高像素、大光圈、小尺寸等要素已成为摄像模组不可逆转的发展趋势，消费者对摄像模组的成像质量要求也不断提高，因此如何使前置摄像模组实现上述功能，也是当今市场亟待解决的难题。Finally, factors such as zoom, anti-shake, high pixels, large aperture, and small size have become an irreversible development trend of camera modules. Consumers have continuously improved the image quality requirements of camera modules. Therefore, how to make the front camera module Realizing the above-mentioned functions is also an urgent problem to be solved in the market today.

根据本申请的一个实施例，提供了一种分体式变焦镜头，其包括：至少两个镜头部件和一个变焦镜片。其中，每个所述镜头部件包括至少一个透镜。所述变焦镜片设置于两个所述的镜头部件之间，并且所述至少两个镜头部件(每个镜头部件包括至少一个透镜)与所述变焦镜片共同构成可成像的光学***。其中，至少一个所述的镜头部件与所述变焦镜片的相对位置由主动校准所确定，其中所述主动校准是基于所述光学***的实际成像结果，对至少一个所述的镜头部件与所述变焦镜片之间的相对位置所进行的调整。这里的实际成像结果可以由感光芯片接受并向外输出的图像数据，基于该实际成像结果可以获得所述光学***的解像力曲线(例如SFR、MTF曲线等)，进而获得所述光学***在当前状态下的成像品质(成像品质例如可以是包含峰值、场曲、像散等多个光学参数的一个或多个加权综合指标)。本实施例中，主动校准可以在多个自由度进行，所述的多个自由度可以包括x、y、z、u、v、w方向，其中x、y方向为水平方向(xoy平面为水平面)，z方向为垂直方向，u、v、w方向分别是绕x、y、z轴旋转的方向。主动校准阶段，镜头部件和/或变焦镜片在x、y、z、u、v、w六个自由度上可调，即通常所说的六轴可调。本实施例中，可以利用通过在镜头中加入变焦镜片来实现变焦功能。相比基于音圈马达(或者其它驱动方式的马达)，本实施例的变焦镜头可以具有更小的尺寸。与此同时，本实施例的变焦镜头采用了分体式结构，且基于主动校准技术对至少一个所述的镜头部件与所述变焦镜片之间的相对位置进行优化，从而补偿各种制造公差和组装公差，使得所述变焦镜头的成像品质提升。According to an embodiment of the present application, a split zoom lens is provided, which includes: at least two lens components and one zoom lens. Wherein, each of the lens components includes at least one lens. The zoom lens is arranged between the two lens components, and the at least two lens components (each lens component includes at least one lens) and the zoom lens together constitute an imageable optical system. Wherein, the relative position of at least one of the lens components and the zoom lens is determined by active calibration, wherein the active calibration is based on the actual imaging result of the optical system, the at least one lens component and the The adjustment of the relative position between the zoom lenses.

进一步地，图1示出了本申请一个实施例中的分体式变焦镜头1000的剖面示意图。参考图1，本实施例中，所述至少两个镜头部件可以包括第一镜头部件100和第二镜头部件200。所述第一镜头部件100可以包括至少一个第一透镜110(本实施例第一透镜110数目为一，需注意本申请并不限于该数目)。所述第二镜头部件200可以包括第二镜筒220和安装在所述第二镜筒220内的至少一个第二透镜210(本实施例中第二透镜210数目为四，需注意本申请并不限于该数目)。所述变焦镜片300位于所述第一镜头部件100和所述第二镜头部件200之间，所述至少一个第一透镜110、所述变焦镜片300和所述至少一个第二透镜210共同构成可成像的所述光学***。并且，所述第一镜头部件100与所述变焦镜片300的相对位置由所述主动校准的结果所确定。本实施例中，变焦镜片300设置在第一镜头部件100和第二镜头部件200之间，可以有效地保护变焦镜片300，提高所述变焦镜头的可靠性和抗冲击能力。Further, FIG. 1 shows a schematic cross-sectional view of a split zoom lens 1000 in an embodiment of the present application. Referring to FIG. 1, in this embodiment, the at least two lens components may include a first lens component 100 and a second lens component 200. The first lens component 100 may include at least one first lens 110 (the number of the first lens 110 in this embodiment is one, and it should be noted that the present application is not limited to this number). The second lens component 200 may include a second lens barrel 220 and at least one second lens 210 installed in the second lens barrel 220 (the number of the second lens 210 in this embodiment is four, and it should be noted that this application does not Not limited to this number). The zoom lens 300 is located between the first lens component 100 and the second lens component 200, and the at least one first lens 110, the zoom lens 300, and the at least one second lens 210 together constitute a The optical system for imaging. Moreover, the relative position of the first lens component 100 and the zoom lens 300 is determined by the result of the active calibration. In this embodiment, the zoom lens 300 is arranged between the first lens component 100 and the second lens component 200, which can effectively protect the zoom lens 300 and improve the reliability and impact resistance of the zoom lens.

进一步地，仍然参考图1，在本申请的一个实施例中，所述变焦镜片300包括可变焦的透光部310和位于所述透光部310周围的驱动部320。所述第一镜头部件100的底面和所述变焦镜片300的所述驱动部320的顶面之间具有第一胶材400，所述第一胶材400在固化后支撑所述第一镜头部件100，使得所述第一镜头部件100与所述变焦镜片300的相对位置保持在主动校准所确定的相对位置。由于基于主动校准技术粘结，因此所述第一镜头部件100的中轴线和所述变焦镜片300的中轴线可以具有不为零的夹角。另一方面，本实施例中，所述变焦镜片300的所述驱动部320的底面与所述第二镜头部件200的顶面之间具有第二胶材500。其中所述第一胶材400的厚度大于所述第二胶材500的厚度。具体来说，本实施例中，所述第一镜头部件100和所述变焦镜片300之间通过主动校准的技术调整相对位置，这使得所述第一镜头部件100和所述变焦镜片300之间的间隙(可称为第一间隙)相对较大，进而导致所述第一胶材400的厚度相对较大，而所述变焦镜片300的所述驱动部320的底面与所述第二镜头部件200的顶面之间的粘结可以基于HA工艺实现，由于基于HA工艺粘结，所以第二胶材500的厚度可以小于第一胶材400的厚度。换句话说，所述变焦镜片300的所述驱动部320的底面与所述第二镜头部件200的顶面之间可以具有第二间隙，第二间隙小于第一间隙。HA为Holder Attach的缩写，可译为镜座组装。在镜座组装中，镜座可以广义地理解为用于保护和支撑光学元件的结构件，对于变焦镜片来说，其驱动部可以视为镜座，对于第二镜头部件来说，其镜筒(即第二镜筒)可以视为镜座。本实施例中，HA工艺可以理解为：将变焦镜片和第二镜头部件进行对位，在对位完成后直接进行粘合。通常来说，基于HA工艺的粘合会尽可能地使两个粘合面(例如驱动部的底面和第二镜筒的顶面)保持平行，换句话说，被粘合的两个实体是平行的。而基于主动校准工艺的粘合，被粘合的两个实体(例如第一镜头部件和变焦镜片)之间可以具有不为零的夹角。HA工艺中，在进行对位和粘合的过程中，感光芯片不需要输出图像(即不需要开图)。而主动校准工艺中，感光芯片是需要输出图像的(即需要开图)。进一步地，在HA工艺中，所述对位主要是指将变焦镜片对准第二镜头部件，这个对准过程可以基于机器视觉技术来实现。本实施例中，第一胶材400可以是UV胶、热固胶或者UV热固胶等。本实施例中，可以将主动校准工艺和HA工艺搭配使用，实现组装工艺简化、组装效率提升的同时，分体式变焦镜头1000的成像品质还能够得以保证。具体来说，本实施例中，只需要基于HA工艺将变焦镜片与第二镜头部件对准，然后固定在第二镜头部件上即可，从而简化了生产工艺，提升了组装效率，而HA工艺可能产生的组装公差，可以交由第一镜头部件的主动校准来补偿，因此整体上看，分体式变焦镜头1000的成像品质仍然可以得到保证。Further, still referring to FIG. 1, in an embodiment of the present application, the zoom lens 300 includes a light-transmitting portion 310 capable of zooming and a driving portion 320 located around the light-transmitting portion 310. There is a first glue 400 between the bottom surface of the first lens component 100 and the top surface of the driving portion 320 of the zoom lens 300, and the first glue 400 supports the first lens component after being cured 100, so that the relative position of the first lens component 100 and the zoom lens 300 is maintained at the relative position determined by the active calibration. Due to the bonding based on active calibration technology, the central axis of the first lens component 100 and the central axis of the zoom lens 300 may have an included angle that is not zero. On the other hand, in this embodiment, a second adhesive material 500 is provided between the bottom surface of the driving portion 320 of the zoom lens 300 and the top surface of the second lens component 200. The thickness of the first rubber material 400 is greater than the thickness of the second rubber material 500. Specifically, in this embodiment, the relative position between the first lens part 100 and the zoom lens 300 is adjusted through active calibration technology, which makes the first lens part 100 and the zoom lens 300 The gap (may be referred to as the first gap) is relatively large, which in turn causes the thickness of the first rubber material 400 to be relatively large, and the bottom surface of the driving portion 320 of the zoom lens 300 and the second lens component The bonding between the top surfaces of the 200 can be achieved based on the HA process. Due to the bonding based on the HA process, the thickness of the second adhesive material 500 may be less than the thickness of the first adhesive material 400. In other words, there may be a second gap between the bottom surface of the driving portion 320 of the zoom lens 300 and the top surface of the second lens component 200, and the second gap is smaller than the first gap. HA is the abbreviation of Holder Attach, which can be translated as lens holder assembly. In the assembly of the lens holder, the lens holder can be broadly understood as a structural component used to protect and support the optical element. For a zoom lens, its driving part can be regarded as a lens holder. For the second lens component, the lens barrel (Ie the second lens barrel) can be regarded as a lens holder. In this embodiment, the HA process can be understood as: aligning the zoom lens and the second lens component, and directly bonding after the alignment is completed. Generally speaking, the bonding based on the HA process will keep the two bonding surfaces (such as the bottom surface of the driving part and the top surface of the second lens barrel) parallel as much as possible. In other words, the two entities being bonded are In parallel. With the bonding based on the active calibration process, there may be a non-zero included angle between the two entities to be bonded (for example, the first lens component and the zoom lens). In the HA process, during the process of alignment and bonding, the photosensitive chip does not need to output images (that is, it does not need to open images). In the active calibration process, the photosensitive chip needs to output the image (that is, the image needs to be opened). Further, in the HA process, the alignment mainly refers to aligning the zoom lens with the second lens component, and this alignment process can be implemented based on machine vision technology. In this embodiment, the first glue 400 may be UV glue, thermosetting glue, UV thermosetting glue, or the like. In this embodiment, the active calibration process and the HA process can be used in combination to simplify the assembly process and improve the assembly efficiency, while the imaging quality of the split zoom lens 1000 can be guaranteed. Specifically, in this embodiment, it is only necessary to align the zoom lens with the second lens component based on the HA process, and then fix it on the second lens component, thereby simplifying the production process and improving the assembly efficiency, while the HA process The possible assembly tolerances can be compensated by the active calibration of the first lens component.

进一步地，图2示出了本申请另一实施例的分体式变焦镜头1000的剖面示意图。参考图2，本实施例中，所述第一镜头部件100由第一透镜110和遮光部件114构成。具体来说，所述第一透镜110具有位于物侧的第一表面和位于像侧的第二表面，其中所述第一表面的中央区域向物侧凸起形成第一凸出部111，所述第一凸出部111的顶面形成用于成像的第一光学区113，所述第一表面还具有围绕在所述第一凸出部111周围的第一结构区112，所述第一凸出部111的侧面连接所述第一光学区113和所述第一结构区112。所述第一凸出部111的周侧具有遮光部件114。进一步地，所述第一结构区112的表面附着遮光材料层。本实施例的分体式变焦镜头1000特别适合与打孔屏配合使用，以作为采用打孔屏的智能手机(或其它电子设备)的前置摄像模组的镜头。打孔屏是指在屏幕的非透明层设置开孔的一种屏幕，通过在屏幕上开孔，打孔屏可以提供摄像模组一入光孔(或称为通光孔)，使得光线可以透过屏幕进入摄像模组，当摄像模组能够正常成像时，屏幕的开孔尺寸需要满足摄像模组的视场需求。在传统的技术方案中，摄像模组(光学镜头)通常置于屏幕开孔之后，使得屏幕开孔需要具有相对较大的尺寸。图3示出了本申请一个实施例中的分体式变焦镜头1000与打孔屏组合后的示意图。参考图2和图3，在本实施例中，为减小屏幕600的开孔601，所述分体式变焦镜头1000的所述第一透镜110(有时也可以称为第一镜片)具有一第一凸出部111，所述第一凸出部111适于伸入屏幕600的开孔601中，使所述第一透镜110的第一表面(即所述分体式变焦镜头1000的入光面)更靠近屏幕600的上表面，进而在相同的镜头视场角规格的前提下减小屏幕600的开孔601尺寸。另一方面，当所述第一透镜110的第一凸出部111伸入屏幕中时，由于第一凸出部111与屏幕开孔601之间的间隙较小，基于传统的设计方案，摄像模组通常难以通过设置马达来驱动镜头运动，因此也难以实现模组的调焦、变焦、防抖等功能。而本实施例中，可以设置一变焦镜片300来实现调焦、变焦、防抖等功能(或者这些功能中的一项)。具体来说，本实施例通过第一透镜110的第一凸出部111和设置于第一透镜110和第二镜头部件200之间的变焦镜片300组合，既可以使得所述摄像模组即的屏幕开孔601减小，又能够使模组具有变焦功能。进一步地，在本实施例中，为避免杂光进入镜头影响正常的光学成像，所述第一透镜110的第一凸出部111周侧设有一遮光部件114，所述遮光部件114的材料可以与第二镜筒220的材料一致。遮光部件114通过胶水与第一透镜110的第一凸出部111粘接，从而避免光线从第一凸出部111的侧面进入镜头。进一步地，所述遮光部件114可以形成一镜头光阑。更进一步地，在所述第一透镜110的第一结构区112上可以设置遮光材料，遮光材料可以避免杂光从第一透镜110的第一结构区112进入镜头(即进入所述的可成像光学***)。遮光材料可以是油墨、黑胶等不透光材料。本实施例中，通过在第一透镜的第一凸出部111周侧设置遮光部件114(而不是在第一透镜的结构区上侧设置遮光部件)，还可以减小遮光部件对第一透镜110的第一凸出部111的凸出高度的影响，使得第一透镜的凸出部可以尽可能地伸入屏幕的开孔601内。并且，在第一透镜110的结构区上通过布设油墨、黑胶等不透光材料作为遮光层，可以在满足第一凸出部111高度不受影响的前提下，减少杂光对镜头的影响。另一方面，本实施例中第一镜头部件取消了第一镜筒，在开孔屏的手机中，摄像模组镜头的入光面越靠近屏幕，同样视场角下所需要的屏幕开孔可以越小，为使镜头可以越靠近屏幕，使镜头具有第一凸出部，而为使第一凸出部可以尽可能的伸入屏幕使入光面更靠近屏幕，可以取消位于第一镜片结构区物侧面的第一镜筒。取消第一镜筒后，第一透镜有时需要直接承靠于屏幕的底面，这样(由于第一透镜的结构区的顶面位置变高)第一透镜与第二镜头部件之间的间隙将增大，而如果间隙过大将导致第一透镜与第二镜头部件难以进行可靠的粘结。如果通过降低第一透镜的结构区的底面的位置，则势必导致第一透镜的整体尺寸增大，进而导致第一透镜的成型难度加大。而本实施例中，在第一透镜和第二镜头部件***变焦镜片，不仅可以增加变焦功能，而且还可以填充上述间隙(即第一透镜与第二镜头部件之间的间隙)。由于第一透镜可以粘接固定在变焦镜片上而不需要和第二镜头部件进行粘接固定，第一透镜的整体尺寸可以减小，第一透镜结构区的尺寸大小也得以降低，从而使得第一透镜的成型难度得以降低，从而有助于制造精度的提升(即减小制造公差)。再者，在另一些情形下，第一透镜的结构区顶面与屏幕的底面之间留有间隙，即第一透镜可以不承靠于屏幕的底面。然而，在开孔屏的手机中，为提高摄像模组的进光量并在相同视场角的前提下减小开孔尺寸，仍然需要使第一透镜的光学面尽可能地接近屏幕上表面。而如果通过增加第一透镜的结构区(即第一结构区)的厚度来垫高第一透镜光学面的位置，将导致第一透镜的加工难度增加，不利于降低制造公差。因此本实施例中，在第一透镜和第二镜头部件***变焦镜片，不仅可以增加变焦功能，而且还可以填充第一透镜与第二镜头部件之间的间隙。这样既可以使第一透镜的光学面更加接近屏幕上表面，又可以使第一透镜的结构区的厚度处于合理范围(可以理解为现有镜片的常见范围)内，从而避免因加工难度增加而引入较大的制造公差。Further, FIG. 2 shows a schematic cross-sectional view of a split zoom lens 1000 according to another embodiment of the present application. Referring to FIG. 2, in this embodiment, the first lens component 100 is composed of a first lens 110 and a light shielding component 114. Specifically, the first lens 110 has a first surface on the object side and a second surface on the image side, wherein the central area of the first surface protrudes toward the object side to form a first protrusion 111, so The top surface of the first protrusion 111 forms a first optical zone 113 for imaging, and the first surface also has a first structure area 112 surrounding the first protrusion 111. The side surface of the protrusion 111 connects the first optical zone 113 and the first structure zone 112. A light shielding member 114 is provided on the peripheral side of the first protrusion 111. Further, a light-shielding material layer is attached to the surface of the first structure region 112. The split zoom lens 1000 of this embodiment is particularly suitable for use with a perforated screen, as a lens for a front camera module of a smart phone (or other electronic device) using a perforated screen. A perforated screen refers to a screen with openings in the non-transparent layer of the screen. By opening a hole on the screen, the perforated screen can provide a light entrance hole (or called a light hole) for the camera module, so that light can be Enter the camera module through the screen. When the camera module can image normally, the aperture size of the screen needs to meet the field of view requirements of the camera module. In traditional technical solutions, the camera module (optical lens) is usually placed behind the screen opening, so that the screen opening needs to have a relatively large size. FIG. 3 shows a schematic diagram of a split zoom lens 1000 combined with a perforated screen in an embodiment of the present application. 2 and 3, in this embodiment, in order to reduce the opening 601 of the screen 600, the first lens 110 (sometimes also referred to as the first lens) of the split zoom lens 1000 has a first lens. A protruding portion 111, the first protruding portion 111 is adapted to extend into the opening 601 of the screen 600, so that the first surface of the first lens 110 (that is, the light incident surface of the split zoom lens 1000) ) Is closer to the upper surface of the screen 600, and the size of the opening 601 of the screen 600 is reduced under the premise of the same lens field angle specification. On the other hand, when the first protrusion 111 of the first lens 110 extends into the screen, since the gap between the first protrusion 111 and the screen opening 601 is small, based on the traditional design solution, the camera It is usually difficult for the module to drive the lens movement by setting a motor, so it is also difficult to realize the module's functions such as focusing, zooming and anti-shake. In this embodiment, a zoom lens 300 can be provided to realize functions such as focusing, zooming, and anti-shake (or one of these functions). Specifically, in this embodiment, the first protrusion 111 of the first lens 110 is combined with the zoom lens 300 disposed between the first lens 110 and the second lens component 200, so that the camera module can be The screen opening 601 is reduced, which can also enable the module to have a zoom function. Further, in this embodiment, in order to prevent stray light from entering the lens and affecting normal optical imaging, a light-shielding member 114 is provided on the peripheral side of the first protrusion 111 of the first lens 110, and the material of the light-shielding member 114 can be It is consistent with the material of the second lens barrel 220. The shading member 114 is bonded to the first protrusion 111 of the first lens 110 by glue, so as to prevent light from entering the lens from the side of the first protrusion 111. Further, the light-shielding component 114 may form a lens diaphragm. Furthermore, a light-shielding material can be provided on the first structure area 112 of the first lens 110, and the light-shielding material can prevent stray light from entering the lens from the first structure area 112 of the first lens 110. Optical system). The light-shielding material can be an opaque material such as ink and vinyl. In this embodiment, by arranging the shading member 114 on the peripheral side of the first protrusion 111 of the first lens (instead of setting the shading member on the upper side of the structure area of the first lens), it is also possible to reduce the effect of the shading member on the first lens. The protrusion height of the first protrusion 111 of the 110 makes the protrusion of the first lens extend into the opening 601 of the screen as much as possible. In addition, by arranging opaque materials such as ink and vinyl as a light shielding layer on the structural area of the first lens 110, the impact of stray light on the lens can be reduced on the premise that the height of the first protrusion 111 is not affected. . On the other hand, the first lens part in this embodiment cancels the first lens barrel. In a mobile phone with a perforated screen, the closer the light-incident surface of the camera module lens is to the screen, the required screen opening under the same angle of view It can be smaller. In order to make the lens closer to the screen, the lens has a first protrusion, and in order to make the first protrusion extend into the screen as much as possible to make the light incident surface closer to the screen, the first lens can be eliminated. The first lens barrel on the side of the structure area. After canceling the first lens barrel, the first lens sometimes needs to directly bear on the bottom surface of the screen, so (due to the higher position of the top surface of the structure area of the first lens) the gap between the first lens and the second lens component will increase. If the gap is too large, it will be difficult to reliably bond the first lens and the second lens component. If the position of the bottom surface of the structure area of the first lens is lowered, the overall size of the first lens will inevitably increase, and the molding of the first lens will become more difficult. However, in this embodiment, inserting a zoom lens into the first lens and the second lens component can not only increase the zoom function, but also fill the above gap (ie, the gap between the first lens and the second lens component). Since the first lens can be glued and fixed on the zoom lens without being glued and fixed with the second lens component, the overall size of the first lens can be reduced, and the size of the first lens structure area can also be reduced, so that the second lens The molding difficulty of a lens can be reduced, thereby contributing to the improvement of manufacturing accuracy (ie, reducing manufacturing tolerances). Furthermore, in other cases, there is a gap between the top surface of the structure area of the first lens and the bottom surface of the screen, that is, the first lens may not bear against the bottom surface of the screen. However, in a mobile phone with an aperture screen, in order to increase the light input of the camera module and reduce the aperture size under the premise of the same angle of view, it is still necessary to make the optical surface of the first lens as close as possible to the upper surface of the screen. However, if the optical surface of the first lens is increased by increasing the thickness of the structure area of the first lens (ie, the first structure area), the processing difficulty of the first lens will increase, which is not conducive to reducing manufacturing tolerances. Therefore, in this embodiment, inserting a zoom lens into the first lens and the second lens part can not only increase the zoom function, but also fill the gap between the first lens and the second lens part. In this way, the optical surface of the first lens can be closer to the upper surface of the screen, and the thickness of the structure area of the first lens can be within a reasonable range (which can be understood as a common range of existing lenses), thereby avoiding the increase in processing difficulty. Introduce larger manufacturing tolerances.

The connecting section 213c may be inclined. The design of this embodiment can make the optical zone of the topmost second lens 210 closer to the zoom lens 300, thereby helping to reduce the height of the split zoom lens 1000 (referring to the split zoom lens 1000 The size in the optical axis direction), and the risk of interference between the second lens 210 and the zoom lens 300 is reduced.
