Description

摄像模块用光学系统
技术领域
本实用新型涉及一种摄像模块用光学系统，特别涉及一种具有调整组件的摄像模块用光学系统。
背景技术
随着科技的发展，人们对于电子产品的高效能、高规格视觉享受的追求越来越高，以丰富更棒的产品使用体验。现今许多电子装置(例如平板电脑或智能手机)都配有镜头模块而具有照相或录影的功能。当使用者使用配有镜头模块的电子装置时，可能会有晃动的情形发生，进而使得镜头模块所拍摄的影像产生模糊。然而，人们对于影像品质的要求日益增高，故镜头模块的防震功能亦日趋重要，此外也追求产品的小型化、轻便化，以便使用者使用。如何提供一种具高品质的摄像模块是为一重要课题。
一些摄像模块内配置有复数个镜头元件，面对高分辨率需求，使得需要更高水准的光学驱动、稳定度与对准性，在调制传递函数(Modulation Transfer Function，MTF)的表现品质能够提高。一些镜头元件的光圈性能，因为低照度(low light)品质要求，需要大光圈型的产品，但是对焦(through of focus，TOF)的焦深(depth of focus)范围会变窄。相关零组件的组装，镜头元件与感光元件若无法实现垂直正交,意即跟光轴有倾斜角度(tilt)存在，若其倾斜角度过大，则TOF的曲线分散，造成影像失焦而模糊。因此，控制镜头元件与感光元件的倾斜角度是一重要课题。

请参阅图1，图1是表示本实用新型一实施例的摄像模块用光学系统20-100的示意图。如图1所示，摄像模块用光学系统20-100可设置于一电子装置(例如相机、平板电脑或手机)内部，作为摄像单元以提供拍摄、录影功能。举例而言，当来自外界的光线沿光入射方向进入摄像模块用光学系统20-100后，光线得以穿过其中的一光学元件20-LS(例如镜头组件)并至感光元件20-IM，以获取影像。以下将详细说明摄像模块用光学系统20-100的详细结构。
前述摄像模块用光学系统20-100包括一光学模块20-OM、一感光模块20-IM与一调整组件20-AS，调整组件20-AS位于光学模块20-OM与感光模块20-IM之间，并设置于光学模块20-OM的一底面20-OMB上，且沿垂直于光学系统20-100的一主轴20-Q(或光学元件20-LS的光轴20-O)的一第一方向20-D1观察，调整组件20-AS与光学模块20-OM不重叠。
前述光学模块20-OM可为一镜头模块，包含一外壳20-H、一活动部20-V与一基座20-10，外壳20-H和活动部20-V设置于基座20-10上，且外壳20-H与基座20-10形成一容纳空间，活动部20-V设置于容纳空间中。前述活动部20-V包含一框架20-20、一承载件20-30、一驱动组件20-MC与一弹性组件20-ES。外壳20-H连接并设置于基座20-10所形成的容纳空间，用以容置前述活动部20-V(包含承载件20-30、驱动组件20-MC与弹性组件20-ES)，可提供保护作用。
承载件20-30用以承载光学元件20-LS，并通过弹性组件20-ES活动地连接基座20-10和框架20-20。驱动组件20-MC设置于承载件20-30和框架20-20上，用以驱动承载件20-30和光学元件20-LS相对于基座20-10、框架20-20移动，以调整光学元件20-LS的姿态或位置，进而达光学自动对焦(Auto-Focusing，AF)或光学防手震(Optical Image Stabilization，OIS)的目的。
关于弹性组件20-ES的详细而言，弹性组件20-ES包含一第一弹性元件20-E1和一第二弹性元件20-E2，分别设置于承载件20-30的上、下两侧，活动地连接承载件20-30和基座20-10与框架20-20，使得承载件20-30可相对于基座20-10与框架20-20活动。
关于驱动组件20-MC之详细而言，其可为一电磁驱动组件(ElectromagneticDriving Assembly)，包含一线圈20-C和一磁性元件20-M，两者分别设置于承载件20-30和框架20-20。其中，磁性元件20-M与线圈20-C两者相互对应。当对驱动组件20-MC施加一施加驱动信号(例如通过一外部电源施加电流至线圈20-C)，磁性元件20-M与线圈20-C之间产生磁力，进而可带动承载件20-30相对于基座20-10移动，以达到光学影像防手震或自动对焦的技术效果。本实施例中的驱动组件20-MC为动磁式，于另一实施例中则可为动圈式。此外，在施加驱动信号之前，前述弹性组件20-ES可让承载件20-30相对基座20-10保持在一初始位置。
驱动组件20-MC可包括一位置感测元件，其可为一位置感应器，举例而言，可为磁阻感应器(Magnetoresistive Sensor，MRS)或是光学感测器(Optical Sensor)，其用以感测活动部20-V、基座20-10的相对位置关系，以利一控制单元(未图示)通过驱动组件20-MC调整两者之间的位置。位置感测元件可被线圈20-C围绕，此配置可充分利用空间，让整个驱动机构的体积达小型化之利。位置感测元件可与线圈20-C共用磁性元件20-M。
于一些实施例中，摄像模块用光学系统20-100还可包括一导磁元件(permeability element)设置于框架20-20与驱动组件20-MC的磁性元件20-M之间，可使磁性元件20-M的磁力往一既定方向集中，以增强驱动组件20-MC驱使承载件20-30移动的磁推力，以及降低磁干扰的作用。于另一实施例中，框架20-20的可嵌入前述导磁元件，使其具有导磁材质，除了可增强磁力(磁性元件20-M与线圈20-C之间)往一既定方向集中外，还可增强活动部20-V的整体机械强度。
参阅图2，前述调整组件20-AS包含复数个调整柱20-A1，设置于基座20-10的底面20-OMB并沿一第二方向延伸20-D2(第二方向20-D2不与光轴20-O垂直，例如平行或大致平行于Z轴)，用以调整光学模块20-OM与感光模块20-IM的相对位置，具体而言，其是调整光学模块20-OM内设置的光学元件20-LS的光轴20-O与感光模块20-IM的主轴20-Q，以使其重叠或平行。于本实施例中，调整组件20-AS包含四个调整柱20-A1，设置于光学模块20-OM的底面20-OMB的边缘处，并位于底面20-OMB的不同侧。需注意的是，于其他实施例中，调整组件20-AS可包含三个调整柱20-A1，设置于光学模块20-OM的底面20-OMB的边缘处，三者皆位于底面20-OMB的不同侧。
详细而言，参阅图3A，当感光模块20-IM和光学模块20-OM组装时，感光模块20-IM的底板20-40(可用于承载感光模块20-IM内的感光元件)的接触表面20-41会接触调整组件20-AS，此时一组合与调节机构20-56的测量装置20-501(例如一角度测量器)测量光学模块20-OM内的光轴20-O与感光模块20-IM的主轴20-Q的角度差，以提供一测量信息。接着，组合机构20-56的一定位装置20-601根据前述测量信息来调整光学模块20-OM与感光模块20-IM之间的相对位置，以使光轴20-O与主轴20-Q重合或平行。于一些实施例中，测量装置20-501可通过光经过光学模块20-OM至感光模块20-IM所产生的影像，根据影像的模糊、对焦程度来判别光学模块20-OM内的光轴20-O与感光模块20-IM的主轴20-Q的之间是否存在角度差异。
继续参阅图3A，当主轴20-Q相对于光轴20-O有相对倾斜或歪斜时(例如光学元件20-LS放置于承载件20-30中并没有完全对齐承载件20-30的中心，会使得光轴20-O、承载件20-30的中心与主轴20-Q并非三者平行或重合)，代表感光模块20-IM并非对齐光学模块20-OM。此时，定位装置20-601会带动感光模块20-IM挤压调整组件20-AS，使得调整组件20-AS的至少一部分在Z轴方向上的高度降低，以让感光模块20-IM对齐光学模块20-OM。如图3A～3B所示，当感光模块20-IM挤压调整组件20-AS时，其底板20-40接触并抵压住前述数个调整柱20-A1，使得调整柱20-A1改变原本形状，此时通过定位装置20-601让感光模块20-IM对齐光学模块20-OM，以达两者组成的对准性。
其中，定位装置20-601包含一夹持件20-6011、限位件20-6012与一定位件20-6013，夹持件20-6011用以夹持光学模块20-OM，限位件20-6012用以限位光学模块20-OM，定位件20-6013则用以承载感光模块20-IM并使其组装于光学模块20-OM。于本实施例中，夹持件20-6011是夹持光学模块20-OM的顶部，限位件20-6012则位在光学模块20-OM两侧以限位光学模块20-OM，避免过大的晃动或移动。当定位件20-6013推动感光模块20-IM向光学模块20-OM时，感光模块20-IM的底板20-40接触调整柱20-A1，通过测量装置20-501得知两者的光轴20-O、主轴20-Q是否平行或重合，以调整感光模块20-IM在不同位置压向调整柱20-A1的力量，如不同力20-F1、20-F2、20-F3，使得调整柱20-A1的形状被改变，进而可使得光轴20-O、主轴20-Q平行或重合。
于一些实施例中，前述底板20-40的接触表面20-41具有金属材质，其可连接至外部一加热电路，以使其加热升温，使得在此接触表面20-41上的调整柱20-A1得以成为融化态，进而改变其形状。于一些实施例中，接触表面20-41为平面。
如此一来，摄像模块用光学系统20-100通过在光学模块20-OM与感光组件20-IM之间设置调整组件20-AS，且调整组件AS的外型得以被改变，使得感光组件IM和光学模块20-OM组装能够精准地调校，以让主轴20-Q与光轴20-O平行或重合，以提升装置所获取的影像品质。
图4是表示本实用新型另一实施例的摄像模块用光学系统20-200与调整，与图1中的摄像模块用光学系统20-100不同的是，本实施例的摄像模块用光学系统20-200具有两个光学模块：一第一光学模块20-OM1和一第二光学模块20-OM2，两者可为相同或类似的组件，或是外型、比例大小不同的组件，而调整组件20-AS具有复数个第一调整柱20-A1(第一调整子组件)和复数个第二调整柱A2(第二调整子组件)。第一光学模块20-OM1、第一调整柱20-A1、一第二光学模块20-OM2、第二调整柱20-A2和感光模块20-IM是沿第一光学元件20-LS1的第一光轴20-O1(或者第二光学元件LS2的第二光轴20-O2、主轴20-Q)按序排列。
当欲使第一、第二光学模块20-OM1、20-OM2、感光模块20-IM三者组装时，定位装置601的夹持件20-6011夹持并限位第一、第二光学模块20-OM1、20-OM2，而定位件20-6012承载感光模块20-IM。首先，第二光学模块20-OM2的上表面20-OMB1上的第一调整柱20-A1压向第一光学模块20-OM1的基座20-10的底面，当第一、第二光学模块20-OM1、20-OM2有相对倾斜时，通过第一调整组件20-A1承靠基座20-10并使第一调整柱20-A1形状改变，并使第一、第二光学模块20-OM1、20-OM2对齐。
接着，感光模块20-IM的底板20-40压向设置在下表面20-OMB2的第二调整柱20-A2，当感光模块20-IM与第二光学模块20-OM2有相对倾斜时，通过第二调整柱20-A2承靠在底板20-40上而被挤压改变形状，直到感光模块20-IM对齐于第二光学模块20-OM2。如此一来，通过上述机制，能使能第一、第二光学模块20-OM1、20-OM2、感光模块20-IM三者对齐，第一、第二光轴20-O1、20-O2与主轴20-Q平行或重合。
于另一些实施例中，第一调整柱20-A1可设置于第一光学模块20-OM1的底面，而第二光学模块20-OM2的上表面20-OMB1压向第一调整柱20-A1。于另一些实施例中，第二调整柱20-A2可设置在感光模块20-IM的底板20-40上，而第二光学模块20-OM2的下表面20-OMB2压向第二调整柱20-A2。
以上说明的第一、第二调整柱20-A1、20-A2设置的位置可作组合，而第一、第二光学模块20-OM1、20-OM2、感光模块20-IM三者的主动移动方亦可作组合。
图5显示数个调整柱20-A1(或20-A2)与数个不同的对手件20-BO1、20-BO2、20-BO3的示意图。前述对手件20-BO1～BO3可如图3A中的感光模块20-IM的底板20-40，或者为图4中的第一光学模块20-OM1的基座20-10、第二光学模块20-OM2的上、下表面20-OMB1、20-OMB2的部分或感光模块20-IM的底板20-40。
于本实施例中，调整柱20-A1具有圆柱结构，其具有一最大宽度20-W1，而对手件20-BO1的接触面则具有一最大宽度20-W2，其中调整柱20-A1的最大宽度20-W1小于对手件的最大宽度20-W2，也就是最大宽度20-W2大于最大宽度20-W1。如此可确保对手件20-BO1压向调整柱20-A1时，能够完全覆盖调整柱20-A1，以利改变调整柱20-A1的形状，提升模块之间的对准精确度。
于一些实施例中，对手件20-BO2具有对应每一调整柱20-A1的凸部20-BOT，朝调整柱20-A1(或20-A2)延伸，搭配图1、4中的实施例，其例如朝光学模块20-OM、20-OM1、20-OM2或感光模块20-IM延伸。复数个调整柱20-A1对应并接触复数个凸部20-BOT，且凸部20-BOT的最大宽度20-W3大于调整柱20-A1的最大宽度20-W1。为求清楚、简单地显示，图5中仅示出一个调整柱20-A1与一个凸部20-BOT。
于一些实施例中，对手件20-BO3的具有复数个凹部20-BOR，其开口是朝光学模块20-OM，复数个调整柱20-A1对应并接触这些凹部20-BOR，且凹部20-BOR的最大宽度20-W4大于调整柱20-A1的最大宽度20-W1。
图6显示多个不同形状的调整柱，包含调整柱20-A1a、20-A1b、20-A1c的示意图。调整柱20-A1a可具有圆柱状或是梯形结构，其中，具有梯形结构的调整柱有两种实施方式20-A1b、20-A1c：邻近对手件20-BO的一侧最大宽度小于远离对手件20-BO的一侧的最大宽度；以及邻近对手件20-BO的一侧的最大宽度大于远离对手件20-BO的一侧的最大宽度。
图7显示多个不同的调整柱20-A1(或20-A2)的端部具有不同形状的示意图，如调整柱20-A1a’、20-A1b’、20-A1c’与20-A1d’。调整柱20-A1a’的端部具有阶梯结构，以形成一延伸部20-A1a’1和一限位面20-A1a’2，当对手件20-BO压向延伸部20-A1a’1而改变其形状时，限位面20-A1a’2可作为对手件20-BO压向延伸部20-A1a’1的限位表面，可防止对手件20-BO过度挤压调整柱20-A1a’。调整柱20-A1b’的延伸部20-A1b’1则具有一渐缩结构。
调整柱20-20-A1c’具有延伸部20-A1c’1与凹陷部20-A1c’2，凹陷部20-A1c’2位于延伸部20-A1c’1的两侧，如此当对手件20-BO压向延伸部20-A1c’1而改变其形状时，变形的延伸部20-A1c’1可往凹陷部20-A1c’2移动，凹陷部20-A1c’2具有容纳变形的延伸部20-A1c’1的效果。调整柱20-A1d’的延伸部20-A1d’1则具有一渐缩结构。
综上所述，本实用新型的实施例提供一种摄像模块用光学系统，具有一主轴，包括：一光学模块，具有一承载空间，用以承载具有一光轴的一光学元件；以及一调整组件，可调整该光学模块的该光轴平行于该主轴，该光学模块与该调整组件是沿该主轴排列，其中沿垂直该主轴的一第一方向观察，该调整组件与该光学模块的该承载空间不相重叠。
本实用新型实施例至少具有以下其中一个优点或技术效果，通过调整组件可调整数个光学模块相互对齐，以及一或数个光学模块与感光模块相互对齐，以提高装置的优良性。此外，由于调整组件可在调整时改变其外型(通常为被挤压而在垂直方向上高度减少)，让光学模块与感光模块之间的调校能够更细致、更精准，大幅提升产品品质。
在本说明书以及权利要求中的序数，例如“第一”、“第二”等等，彼此之间并没有顺序上的先后关系，其仅用于标示区分两个具有相同名字的不同元件。
上述的实施例以足够的细节叙述使所属技术领域的技术人员能通过上述的描述实施本实用新型所公开的装置，以及必须了解的是，在不脱离本实用新型的构思以及范围内，当可做些许变动与润饰，因此本实用新型的保护范围当视权利要求所界定者为准。
