Description

前置摄像头的组装方法、组装结构及电子设备
本申请要求于2022年8月30日提交国家知识产权局、申请号为202211047506.9、申请名称为“前置摄像头的组装方法、组装结构及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及摄像元件的技术领域，并且更具体地，涉及一种具有前置摄像头的电子设备。
背景技术
当前业界终端电子设备的屏下前置摄像头都在追求极致的镜头黑边，从而能够减小镜头黑边对用户的视觉影响，以及提高电子设备的屏占比。镜头黑边通常受限于镜头与摄像头开孔之间的间隙尺寸，二者的间隙尺寸越大则镜头黑边越宽，用户的视觉体验则越差，同时屏幕的显示区域则越小。
相关技术中的前置摄像头的组装结构，镜头在摄像头开孔内的安装位置是由中框上的限位槽与摄像头本体的外壁所决定的，这就导致镜头与摄像头开孔之间关联组装的零件较多，尺寸链较长，最终形成的累计公差较大，因此必须将摄像头开孔的孔径设计略大，从而能够满足镜头在摄像头开孔内的偏心量。
然而，过大的摄像头开孔增加了其与镜头的间隙尺寸，进而无法减小镜头黑边对用户的视觉影响，以及难以提高电子设备的屏占比，并且通过中框上的限位槽和摄像头本体的外壁配合安装，其提高了前置摄像头的加工及组装难度。
发明内容
本申请的目的在于提供了一种前置摄像头的组装方法、组装结构及电子设备，通过视觉定位系统将镜头与摄像头开孔精准定位后，再将摄像头本体与中框固定连接，从而将镜头与摄像头开孔之间关联组装的零件降低到最少、尺寸链最短，进而可以将摄像头开孔的孔径设计较小，由此减小了摄像头开孔与镜头的间隙尺寸，使得镜头黑边对用户的视觉影响降低，并且提高了电子设备的屏占比。并且，可以忽略中框上限位槽以及摄像头本体的外壁的加工精度，同时对于中框向触控屏安装时的精度要求也变低，总体降低了前置摄像头的加工及组装难度。
第一方面，本申请提供了一种前置摄像头的组装方法，包括：
提供中框，所述中框具有容纳摄像头本体的容置槽，所述容置槽的尺寸满足所述摄像头本体在组装时，所述摄像头本体的镜头与触控屏的摄像头开孔的对中调整余量；
将所述中框与所述触控屏组装成一体结构，所述一体结构具有连通所述容置槽和所述摄像头开孔的孔道；
使用视觉定位系统移动所述摄像头本体，使所述镜头经所述孔道伸入所述摄像头开孔内并保持对中设置，将所述摄像头本体固定于所述容置槽内。
本申请提供的前置摄像头的组装方法，通过视觉定位系统将镜头与摄像头开孔精准定位后，再将摄像头本体与中框固定连接，整个组装过程只需要考虑镜头的外形公差、摄像 头开孔的公差以及视觉定位系统的组装公差即可，从而将镜头与摄像头开孔之间关联组装的零件降低到最少、尺寸链最短，实现最小的累计公差，进而可以将摄像头开孔的孔径设计较小，由此减小了摄像头开孔与镜头的间隙尺寸，使得镜头黑边对用户的视觉影响降低，并且提高了电子设备的屏占比。
在相关技术中，摄像头开孔与镜头的间隙尺寸通常在0.3～0.5mm之间，而本申请中，摄像头开孔与镜头的间隙尺寸可以做到0.2mm左右，可以降低镜头黑边对用户的视觉影响。
此外，本申请提供的前置摄像头的组装方法还具有加工及组装难度低的优点，具体表现在：在相关技术中，限位槽不仅起到紧固摄像头本体的作用，同时还起到定位镜头的作用，由此对于限位槽的尺寸精度和摄像头本体的外壁的尺寸精度要求较高，同时对于中框向触控屏上进行安装时的安装精度也要求较高，反观本申请中的容置槽和摄像头本体，由于是采用视觉定位系统直接将镜头与摄像头开孔进行精准定位的，容置槽只起到收容摄像头本体的作用，因此对于容置槽的尺寸精度和摄像头本体的外壁的尺寸精度要求较低，容置槽的尺寸只需要镜头与摄像头开孔的对中调整余量即可，同时对于中框向触控屏上进行安装时的安装精度也要求较低，因此总体降低了前置摄像头的加工及组装难度。
在一种可能的设计中，所述将所述摄像头本体固定于所述容置槽内的步骤中，包括：
将所述摄像头本体粘接固定于所述容置槽内。
可选地，摄像头本体与容置槽的粘接位置可以在容置槽的侧壁或者底壁上。

可选地，在粘接摄像头本体与容置槽时，可以有两种实施方式：一种是将胶黏剂或者双面胶提前贴附在摄像头本体和/或容置槽的粘接位置，然后在视觉定位系统对镜头与摄像头开孔进行对中设置的同时，顺势将摄像头本体与容置槽的槽壁粘接；另一种是在视觉定位系统对镜头与摄像头开孔进行对中设置后，让视觉定位系统的机械手保持不动，在摄像头本体与容置槽的间隙内通过点胶设备注入胶黏剂。
在一种可能的设计中，所述使用视觉定位系统移动所述摄像头本体，使所述镜头经所述孔道伸入所述摄像头开孔内并保持对中设置，将所述摄像头本体固定于所述容置槽内的步骤中，包括：

通过摄像头支架与中框进行固定连接，以将摄像头本体固定于容置槽内，此种固定方式的实施对象是摄像头支架和中框，可以避免直接接触摄像头本体，从而能够防止在组装过程中造成摄像头本体的损坏，能够降低组装环节的物损。同时，在上料环节，以及视觉定位系统在拾取摄像头本体时，吸附或者夹取的实施对象也是摄像头支架，同样避免直接接触摄像头本体，能够有效避免在物料转运过程中造成摄像头本体的损坏，进而能够降低物损。
可选地，摄像头支架与摄像头本体之间的固定连接方式多样，可以通过胶黏剂粘接、焊接、锁扣连接或者紧固件连接。

在一种可能的设计中，所述将所述摄像头支架与所述中框固定连接的步骤中，包括：
将所述摄像头支架与所述中框粘接固定。
通过胶黏剂粘接的方式可以更牢固地固定摄像头本体与中框，且无需其他的连接结构即可实现二者之间的相互固定，可以使前置摄像头组装结构的整体性更好。此外，通过胶黏剂粘接的方式还可以不用考虑其他连接结构的尺寸精度，从而降低加工和组装难度。
在一种可能的设计中，所述摄像头支架的两端开设有第一安装孔，所述中框对应开设有第二安装孔，所述将所述摄像头支架与所述中框固定连接的步骤中，包括：
在所述第一安装孔和所述第二安装孔内设置紧固件以将所述摄像头支架与所述中框固定连接。
采用紧固件锁紧摄像头支架与中框的方式，能够便于前摄像头拆卸返修，且能够重复组装进行复用。
在将摄像头支架与中框进行粘接预固定之后，可以将摄像头支架和中框作为一个整体移出视觉定位系统工位，然后可以在其他工位进行紧固件锁紧，从而能够提高视觉定位系统的对中设置效率，避免摄像头支架与中框长时间占用视觉定位系统而造成组装效率降低。此外，将摄像头支架与中框采用胶黏剂粘接和紧固件连接双重加固，能够保证充分摄像头支架与中框的连接强度。综上，本实施例具有组装效率高，抗震效果好的优点。
可选地，紧固件可以是螺钉或者销钉。
具体地，紧固件是螺钉，第二安装孔的孔壁开设有与螺钉适配的螺纹，在螺钉旋合在第二安装孔内时，螺钉的头部压紧在第一安装孔的孔口处。
具体地，紧固件是销钉，第二安装孔与销钉过盈配合，在销钉插接在第二安装孔内时，销钉的头部压紧在第一安装孔的孔口处。

将所述镜头穿过所述避让孔后，所述摄像头本体粘接固定于所述收容槽内。
在一种可能的设计中，所述将所述摄像头支架与所述中框固定连接的步骤中，包括：
将所述收容槽的槽壁外侧粘接固定于所述容置槽内。
可选地，收容槽的槽壁外侧尺寸小于容置槽的尺寸，使得收容槽可以在容置槽内进行水平方向位移，从而使得在镜头与摄像头开孔进行对中调整时，摄像头支架相对于中框在水平方向具有一定的调整余量。
在一种可能的设计中，所述摄像头支架的两端开设有第一安装孔，所述中框对应开设有第二安装孔，所述将所述摄像头支架与所述中框固定连接的步骤中，包括：

在将摄像头支架与中框进行粘接预固定之后，可以将摄像头支架和中框作为一个整体移出视觉定位系统工位，然后可以在其他工位进行紧固件锁紧，从而能够提高视觉定位系 统的对中设置效率，避免摄像头支架与中框长时间占用视觉定位系统而造成组装效率降低。此外，本实施例中将摄像头支架与中框采用胶黏剂粘接和紧固件连接双重加固，能够保证充分摄像头支架与中框的连接强度。并且，由于摄像头支架是以嵌入方式与中框固定连接的，更进一步地提高了摄像头支架与中框的连接强度。
第二方面，本申请提供了一种前置摄像头的组装结构，包括：
摄像头本体，具有位于前端的镜头；
触控屏，开设有用于容纳所述镜头的摄像头开孔；

本申请提供的前置摄像头的组装结构，在中框设有尺寸满足镜头与摄像头开孔进行对中调整的容置槽，可以通过视觉定位系统将镜头与摄像头开孔精准定位后，再将摄像头本体固定于容置槽内，从而将镜头与摄像头开孔之间关联组装的零件降低到最少、尺寸链最短，实现最小的累计公差，进而可以将摄像头开孔的孔径设计较小，由此减小了摄像头开孔与镜头的间隙尺寸，使得镜头黑边对用户的视觉影响降低，并且提高了电子设备的屏占比。
此外，本申请中的容置槽只起到收容摄像头本体的作用，其并不参与定位镜头在摄像头开孔内位置的作用，因此在本申请中对于容置槽的尺寸精度要求较低，容置槽的尺寸只需要满足镜头与摄像头开孔的对中调整余量即可，同时，对于摄像头本体的外壁的尺寸精度以及中框向触控屏上进行安装时的安装精度也要求较低，因此总体降低了前置摄像头的加工及组装难度。
在一种可能的设计中，还包括：
摄像头支架，所述摄像头本体通过所述摄像头支架与所述中框固定连接。
可选地，摄像头支架可以是个平板结构，或者是壳体结构，还或者是框架结构。

在一种可能的设计中，所述摄像头支架的两端边沿具有内扣式翻边，所述翻边的内侧设置胶黏剂用以将所述摄像头支架与所述中框粘接固定。
翻边主要有两个作用：一是能够起到限位镜头安装深度的作用，翻边的高度能够决定镜头伸入摄像头开孔的深度，从而能够提高前置摄像头的组装精度；二是能够防止胶黏剂向外溢出，翻边将摄像头支架与中框之间支撑出了一定的空间，该空间能够容纳胶黏剂，可以避免在将摄像头支架与中框进行按压时胶黏剂从二者的间隙内挤压而溢出。
在一种可能的设计中，所述翻边沿着所述摄像头支架的端部边沿环绕半圈设置，以将所述胶黏剂包围。
以将胶黏剂完全包围，进一步防止胶黏剂向外溢出。
在一种可能的设计中，所述摄像头支架的两端开设有第一安装孔，所述中框开设有与所述第一安装孔对应的第二安装孔，所述第一安装孔和所述第二安装孔内设置紧固件以将 所述摄像头支架与所述中框固定连接。
在一种可能的设计中，所述第一安装孔的孔径大于所述第二安装孔的孔径，以使得所述摄像头支架相对于所述中框具有调整余量。
由于第一安装孔的孔径大于第二安装孔的孔径，使得第一安装孔相对于第二安装孔能够在一定范围偏离，以使得在镜头与摄像头开孔进行对中调整时，摄像头支架相对于中框在水平方向具有一定的调整余量。
可选地，摄像头本体与中框之间设置有弹性缓冲体，起到缓冲振动、防止镜头撞伤的作用。同时，弹性缓冲体还具有密封防尘作用，避免灰尘等进入摄像头内部而影响采光质量。

在一种可能的设计中，所述收容壳与所述摄像头本体的间隙内填充有导热剂。

在一种可能的设计中，所述收容槽的槽壁外侧尺寸小于所述容置槽的尺寸，以使得所述摄像头支架相对于所述中框具有调整余量。
在一种可能的设计中，所述摄像头支架的两端开设有第一安装孔，所述中框开设有与所述第一安装孔对应的第二安装孔，所述第一安装孔和所述第二安装孔内设置紧固件以将所述摄像头支架与所述中框固定连接。
在一种可能的设计中，所述第一安装孔的孔径大于所述第二安装孔的孔径，以使得所述摄像头支架相对于所述中框具有调整余量。

第三方面，本申请提供了一种电子设备，包括上述前置摄像头的组装结构。
可选地，该电子设备为手机，此外，电子设备还可以为笔记本电脑、平板电脑、电子手表中的任意一种。
本申请中的电子设备，由于采用了上述的前置摄像头的组装结构，因此该电子设备的前置摄像头的镜头黑边更小，屏占比更高，除此之外，对于零部件的尺寸精度以及安装精度也要求较低，总体降低了电子设备的加工及组装难度，同时也降低了生产制造成本。

在本申请的描述中，需要说明的是，术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
图1是相关技术中的电子设备的示意图。图2是相关技术中的前置摄像头的示意图。
如图1和图2所示，在当前业界终端电子设备的屏下前置摄像头都在追求极致的镜头黑边70，从而能够减小镜头黑边70对用户的视觉影响，以及提高电子设备的屏占比。
图3是图1中A-A的剖视图，如图3所示，镜头黑边70通常受限于镜头12与摄像头开孔21之间的间隙尺寸L，二者的间隙尺寸L越大则镜头黑边70越宽，用户的视觉体验则越差，同时屏幕的显示区域则越小。因此，如何减小镜头12与摄像头开孔21的间隙尺寸L，是减小甚至消除镜头黑边70的有效手段。然而，目前的前置摄像头组装结构并不能将镜头12与摄像头开孔21的间隙尺寸L做到极致，具体原因如下。
图3是相关技术中的前置摄像头的组装结构示意图。如图3所示，中框30设置有用于限位摄像头本体11的限位槽34，摄像头本体11直接卡接固定于限位槽34内，并且在摄像头本体11安装到位时，镜头12恰好伸入至摄像头开孔21内。可见，镜头12在摄像头开孔21内的安装位置是由中框30上的限位槽34与摄像头本体11的外壁所决定的，这就导致镜头12与摄像头开孔21之间关联组装的零件较多，尺寸链较长，比如触控屏20，由于其是多层堆叠结构，自身就具有四到五个尺寸链，而最终到镜头12与摄像头开孔21之间时尺寸链多达十个以上，由此最终形成的累计公差较大，因此必须将摄像头开孔21的孔径设计略大，从而能够满足镜头12在摄像头开孔21内的偏心量。
然而，过大的摄像头开孔21增加了其与镜头12的间隙尺寸L，进而无法减小镜头黑边70对用户的视觉影响，以及难以提高电子设备的屏占比。
此外，在原相关技术的前置摄像头的组装结构中，为了确保镜头12在摄像头开孔21内的安装精度，不仅对于镜头12和摄像头开孔21的尺寸精度要求高，并且由于是通过中框30上的限位槽34和摄像头本体11的外壁配合安装的，其对于中框30限位槽34以及摄像头本体11的外壁的加工精度要求也较高，同时还对于中框30向触控屏20安装时的精度也要求高，总体而言，均提高了前置摄像头的加工及组装难度。
因此，为了解决上述技术问题，本申请提供了一种前置摄像头的组装方法、组装结构及电子设备，通过视觉定位系统将镜头12与摄像头开孔21精准定位后，再将摄像头本体11与中框30固定连接，从而将镜头12与摄像头开孔21之间关联组装的零件降低到最少、尺寸链最短，实现最小的累计公差，进而可以将摄像头开孔21的孔径设计较小，由此减小了摄像头开孔21与镜头12的间隙尺寸L，使得镜头黑边70对用户的视觉影响降低，并且提高了电子设备的屏占比。并且，由于是直接将镜头12与摄像头开孔21进行精准定位的，再将摄像头本体11与中框30通过其他方式固定连接，由此可以忽略中框30上限位槽34以及摄像头本体11的外壁的加工精度，同时对于中框30向触控屏20安装时的精度要求也变低，总体降低了前置摄像头的加工及组装难度。
现结合附图详细描述本申请提供的前置摄像头的组装方法、组装结构及电子设备。
图4是本申请实施例提供的前置摄像头的组装方法的一例的流程图。图5是本申请实 施例提供的前置摄像头的组装方法的一例的示意图。其中，图5中的(a)是中框30与触控屏20未连接时的示意图；图5中的(b)是中框30与触控屏20连接后与摄像头本体11的示意图；图5中的(c)是镜头12与摄像头开孔21在对中设置时的示意图；图5中的(d)是摄像头本体11与中框30连接后的示意图。
如图4、图5所示，本申请实施例提供了一种前置摄像头的组装方法，该组装方法包括如下步骤：
步骤101，如图5中的(a)所示，提供中框30。其中，中框30具有容纳摄像头本体11的容置槽32，容置槽32的尺寸满足摄像头本体11在组装时，摄像头本体11的镜头12与触控屏20的摄像头开孔21的对中调整余量。
步骤102，如图5中的(b)所示，将中框30与触控屏20组装成一体结构。其中，一体结构具有连通容置槽32和摄像头开孔21的孔道31。
步骤103，如图5中的(c)和(d)所示，使用视觉定位系统(图中未绘制)移动摄像头本体11，使镜头12经孔道31伸入摄像头开孔21内并保持对中设置，将摄像头本体11固定于容置槽32内。
其中，需要说明的是，本申请实施例中的容置槽32不同于相关技术中的限位槽34，本申请实施例中的容置槽32起到收容摄像头本体11的作用，同时还用于增加中框30与摄像头本体11的重叠面积，进而能够涂覆更多的胶黏剂50进行粘接固定，以确保摄像头本体11与中框30的固定连接强度。本申请实施例中容置槽32，相较于相关技术中限位槽34的尺寸精度要求并不严苛，容置槽32的形状大致满足摄像头本体11的外形即可，以能够使摄像头本体11顺利地置于容置槽32内，同时容置槽32的尺寸满足镜头12与摄像头开孔21进行对中时的调整余量即可，以避免在对中时容置槽32的槽壁对摄像头本体11造成干涉。因此，相比较相关技术中具有严格尺寸要求的限位槽34，本实施例中的容置槽32的尺寸要求较低，加工难度较小。
可选地，视觉定位系统主要包括机械手、吸取装置、视觉定位装置以及XYθ移动平台。在本申请实施例中的工作过程为：驱动机构驱动机械手移动，让吸取装置将摄像头本体11从外部的输料装置中取走，此时，第一视觉定位装置对摄像头本体11的镜头12进行快速图像处理，并记录镜头12的坐标信息，第二视觉定位装置对触控屏20的摄像头开孔21进行快速图像处理，并记录摄像头开孔21的坐标信息；第一视觉定位装置将镜头12的坐标信息与摄像头开孔21的坐标信息进行分析后反馈给XYθ移动平台，吸取装置在XYθ移动平台的带动下对摄像头本体11进行初步位置调整；驱动机构驱动机械手移动，使吸取装置将摄像头本体11移到触控屏20的上方，机械手带动吸取装置和摄像头本体11下降，将镜头12伸入摄像头开孔21内，然后吸取装置在XYθ移动平台的带动下对摄像头本体11再进行细微且准确的位置调整，以对镜头12的坐标误差进行补偿，使镜头12与摄像头开孔21保持对中设置。
可选地，在吸取装置从外部的输料装置中吸取摄像头本体11时，可以先再将摄像头本体11移送到整位治具，整位治具对摄像头本体11进行大概的位置调整，以使摄像头本体11得到初步定位，然后再由吸取装置从整位治具中吸取摄像头本体11，由此可以大大地减少对中时误差，进一步地提高摄像头本体11的安装精度。
可选地，使用视觉定位系统将镜头12与摄像头开孔21保持对中设置的同时，将摄像 头本体11固定于容置槽32内，其固定方式多样，可以将摄像头本体11直接进行粘接于容置槽32内，或者中框30与摄像头本体11之间通过额外增设的部件间接连接，比如后述实施例中的摄像头支架40，摄像头本体11预先与摄像头支架40连接，之后中框30再与摄像头支架40进行粘接或者紧固件44连接，更为详细的描述请参见后文。
本申请实施例提供的前置摄像头的组装方法，通过视觉定位系统将镜头12与摄像头开孔21精准定位后，再将摄像头本体11与中框30固定连接，整个组装过程只需要考虑镜头12的外形公差、摄像头开孔21的公差以及视觉定位系统的组装公差即可，从而将镜头12与摄像头开孔21之间关联组装的零件降低到最少、尺寸链最短，实现最小的累计公差，进而可以将摄像头开孔21的孔径设计较小，由此减小了摄像头开孔21与镜头12的间隙尺寸，使得镜头黑边70对用户的视觉影响降低，并且提高了电子设备的屏占比。
相关技术中，摄像头开孔21与镜头12的间隙尺寸L通常在0.3～0.5mm之间，而本申请实施例中，摄像头开孔21与镜头12的间隙尺寸L′可以做到0.2mm左右，可以降低镜头黑边70对用户的视觉影响。
此外，本申请实施例还具有加工及组装难度低的优点，具体表现在：在相关技术中，限位槽34不仅起到紧固摄像头本体11的作用，同时还起到定位镜头12的作用，由此对于限位槽34的尺寸精度和摄像头本体11的外壁的尺寸精度要求较高，同时对于中框30向触控屏20上进行安装时的安装精度也要求较高，反观本申请实施例中的容置槽32和摄像头本体11，由于是采用视觉定位系统直接将镜头12与摄像头开孔21进行精准定位的，容置槽32只起到收容摄像头本体11的作用，因此对于容置槽32的尺寸精度和摄像头本体11的外壁的尺寸精度要求较低，容置槽32的尺寸只需要镜头12与摄像头开孔21的对中调整余量即可，同时对于中框30向触控屏20上进行安装时的安装精度也要求较低，因此总体降低了前置摄像头的加工及组装难度。

同时，在上料环节，以及视觉定位系统在拾取摄像头本体11时，吸附或者夹取的实施对象也是摄像头支架40，同样避免直接接触摄像头本体11，能够有效避免在物料转运过程中造成摄像头本体11的损坏，进而能够降低物损。
可选地，摄像头支架40与摄像头本体11之间的固定连接方式多样，可以通过胶黏剂50粘接、焊接、锁扣连接或者紧固件44连接。
可选地，摄像头支架40与中框30之间的固定连接方式多样，可以通过胶黏剂50粘接、焊接、或者紧固件44连接。

将摄像头本体11粘接固定于摄像头支架40的中部外凸形成的收容壳41内。
本实施例中，通过将摄像头本体11粘接固定于收容壳41内，使得收容壳41可以将摄像头本体11外漏在容置槽32之外的部分能够很好的保护，避免摄像头本体11在组装时被其他部件撞击而受损。同时通过胶黏剂50粘接的方式可以更牢固地固定摄像头本体11与摄像头支架40，实施起来比较简单。

本实施例中，通过胶黏剂50粘接的方式可以更牢固地固定摄像头本体11与中框30，且无需其他的连接结构(比如紧固件44等)即可实现二者之间的相互固定，可以使前置摄像头组装结构的整体性更好。此外，通过胶黏剂50粘接的方式还可以不用考虑其他连接结构的尺寸精度，从而降低加工和组装难度。
可选地，粘接摄像头本体11与中框30，也可以有两种实施方式：一种是将胶黏剂50提前涂覆在摄像头本体11和/或中框30的粘接位置，然后在视觉定位系统对镜头12与摄像头开孔21进行对中设置的同时，顺势将摄像头本体11与中框30粘接；另一种是在视觉定位系统对镜头12与摄像头开孔21进行对中设置后，让视觉定位系统的机械手保持不动，在摄像头本体11与中框30的粘接处间隙内通过点胶设备注入胶黏剂50。
图9是本申请实施例提供的前置摄像头的组装方法的另一例的流程图。
如前所述，摄像头支架40与中框30可以通过紧固件44锁紧，具体实施方式如本申请提供的一种实施例中，摄像头支架40的两端开设有第一安装孔43，中框30开设有与第一安装孔43对应的第二安装孔33，基于此设计，如图9所示，该组装方法包括：

本实施例中，采用紧固件44锁紧摄像头支架40与中框30的方式，能够便于前摄像头拆卸返修，且能够重复组装进行复用。
图10是本申请实施例提供的前置摄像头的组装方法的另一例的流程图。图11是本申请实施例提供的前置摄像头的组装方法的另一例的示意图。其中，图11中的(a)是摄像头本体11与摄像头支架40未连接时的示意图；图11中的(b)是中框30与触控屏20未连接时的示意图；图11中的(c)是摄像头本体11与摄像头支架40、中框30与触控屏20连接后的示意图；图11中的(d)是镜头12与摄像头开孔21在对中设置时的示意图；图11中的(e)是摄像头支架40与中框30粘接预固定后的示意图；图11中的(f)是摄像头支架40与中框30通过紧固件44锁紧后的示意图。
上述实施例分别介绍了摄像头支架40与中框30通过胶黏剂50粘接或紧固件44连接的两种方式，为了提高摄像头支架40与中框30的连接强度，还可以将胶黏剂50粘接和紧固件44连接同时实施。具体为：如图10和图11所示，在本申请提供的一种实施例中，该组装方法包括：

本实施例中，在将摄像头支架40与中框30进行粘接预固定之后，可以将摄像头支架40和中框30作为一个整体移出视觉定位系统工位，然后可以在其他工位进行紧固件44锁紧，从而能够提高视觉定位系统的对中设置效率，避免摄像头支架40与中框30长时间占用视觉定位系统而造成组装效率降低。此外，本实施例中将摄像头支架40与中框30采用胶黏剂50粘接和紧固件44连接双重加固，能够保证充分摄像头支架40与中框30的连接强度。综上，本实施例具有组装效率高，抗震效果好的优点。
如图11中的(d)和(e)所示，在本申请提供的一种实施例中，第一安装孔43的孔径大于第二安装孔33的孔径，以使得摄像头支架40相对于中框30具有调整余量。
本实施例中，由于第一安装孔43的孔径大于第二安装孔33的孔径，使得第一安装孔43相对于第二安装孔33能够在一定范围偏离。在镜头12与摄像头开孔21进行对中调整时，摄像头支架40相对于中框30在水平方向的位移也具有一定的调整余量。
可选地，紧固件44可以是螺钉或者销钉。
具体地，紧固件44是螺钉，第二安装孔33的孔壁开设有与螺钉适配的螺纹，在螺钉旋合在第二安装孔33内时，螺钉的头部压紧在第一安装孔43的孔口处。

可选地，收容槽45的槽壁外侧尺寸小于容置槽32的尺寸，使得收容槽45可以在容置槽32内进行水平方向位移，从而使得在镜头12与摄像头开孔21进行对中调整时，摄像头支架40相对于中框30在水平方向具有一定的调整余量。
基于上述摄像头支架40具有内凹形成的收容槽45的设计，在本申请提供的一种实施例中，摄像头支架40的两端开设有第一安装孔43，中框30开设有与第一安装孔43对应的第二安装孔33，将摄像头支架40与中框30固定连接的步骤中，具体包括：

如图12和图13所示，在本申请提供的一种实施例中，该组装方法包括：
步骤601，如图13中的(a)所示，提供中框30。
步骤602，如图13中的(b)和(c)所示，将中框30与触控屏20组装成一体结构。
步骤603，如图13中的(a)和(c)所示，将镜头12穿过避让孔46后，摄像头本体11粘接固定于收容槽45内。
步骤604，如图13中的(d)和(e)所示，使用视觉定位系统移动摄像头支架40和摄像头本体11，使镜头12经孔道31伸入摄像头开孔21内并保持对中设置，将收容槽45的槽壁外侧粘接预固定于容置槽32内。
步骤605，如图13中的(f)所示，在第一安装孔43和第二安装孔33内设置紧固件44以将摄像头支架40与中框30固定连接，以使摄像头本体11固定于容置槽32内。

图14是本申请实施例提供的前置摄像头组装结构的一例的剖视图。
如图14所示，本申请实施例还提供了一种前置摄像头的组装结构，包括摄像头本体11、触控屏20以及中框30。
摄像头本体11具有位于前端的镜头12。
触控屏20开设有用于容纳镜头12的摄像头开孔21。
中框30与触控屏20固定连接，中框30具有尺寸满足镜头12与摄像头开孔21进行对中调整的容置槽32，容置槽32与摄像头开孔21通过孔道31相通，摄像头本体11固定于容置槽32内，镜头12穿过孔道31并对中设置于摄像头开孔21内。
本申请提供的前置摄像头的组装结构，在中框30设有尺寸满足镜头12与摄像头开孔21进行对中调整的容置槽32，可以通过视觉定位系统将镜头12与摄像头开孔21精准定位后，再将摄像头本体11固定于容置槽32内，从而将镜头12与摄像头开孔21之间关联组装的零件降低到最少、尺寸链最短，实现最小的累计公差，进而可以将摄像头开孔21的孔径设计较小，由此减小了摄像头开孔21与镜头12的间隙尺寸，使得镜头黑边70对 用户的视觉影响降低，并且提高了电子设备的屏占比。
此外，由于是采用视觉定位系统直接将镜头12与摄像头开孔21进行精准定位的，本申请实施例中的容置槽32只起到收容摄像头本体11的作用，其并不参与定位镜头12在摄像头开孔21内位置的作用，因此在本申请中对于容置槽32的尺寸精度要求较低，容置槽32的尺寸只需要满足镜头12与摄像头开孔21的对中调整余量即可，同时，对于摄像头本体11外壁的尺寸精度以及中框30向触控屏20上进行安装时的安装精度也要求较低，因此总体降低了前置摄像头的加工及组装难度。
可选地，中框30与摄像头本体11进行固定连接的方式多样，可以将中框30与摄像头本体11直接进行粘接，或者中框30与摄像头本体11通过额外增设的部件间接连接，比如后述实施例中的摄像头支架40，摄像头本体11预先与摄像头支架40连接，之后中框30再与摄像头支架40进行粘接或者紧固件44连接，详细描述请参见后文。
如前所述，中框30与摄像头本体11可以直接进行粘接，也就是如本实施例中，摄像头本体11通过胶黏剂50粘接固定于容置槽32内。特别要说明的是，本实施例中的容置槽32不同于相关技术中的限位槽34，本实施例中的容置槽32只起到收容摄像头本体11的作用，同时还用于增加中框30与摄像头本体11的重叠面积，从而使位于容置槽32内的摄像头本体11与槽壁由足够的接触面积，能够涂覆更多的胶黏剂50进行粘接固定，以确保摄像头本体11与中框30的固定连接强度。对于容置槽32的尺寸要求并不严苛，只需要容置槽32的形状大致满足摄像头本体11的外形即可，进而使得摄像头本体11能够顺利的置于容置槽32内。因此，相比较相关技术中加工具有严格尺寸要求的限位槽34，本实施例中的容置槽32的尺寸要求较低，加工难度较小。
本实施例中，通过胶黏剂50粘接的方式可以更牢固地固定摄像头本体11与中框30，且无需其他的连接结构即可实现二者之间的相互固定，可以使电子设备的整体性更好。此外，通过胶黏剂50粘接的方式还可以不用考虑其他连接结构的尺寸精度，从而降低加工和组装难度。
可选地，胶黏剂50可以通过预涂覆的方式设置在容置槽32的槽底壁；或者，可以待摄像头本体11置于容置槽32内之后，在摄像头本体11与容置槽32的槽壁之间的间隙内通过点胶方式注入胶黏剂50。
图15是本申请实施例提供的前置摄像头组装结构的另一例的剖视图。
如图15所示，在本申请提供的一种实施例中，组装结构还包括：
摄像头支架40，分别与摄像头本体11和中框30固定连接，以使得摄像头本体11通过摄像头支架40与中框30固定连接。
如前所述，中框30与摄像头本体11可以通过额外增设的部件间接连接，也就是如本实施例中，在摄像头本体11与中框30之间增设摄像头支架40，先将摄像头支架40与摄像头本体11连接，然后再将摄像头支架40与中框30连接。
可选地，摄像头支架40与摄像头本体11之间的固定连接方式多样，可以通过胶黏剂50粘接、焊接、锁扣连接或者紧固件44连接。
具体地，摄像头支架40与摄像头本体11通过胶黏剂50粘接，具有组装快、结构小等优点。
可选地，摄像头支架40与中框30之间的固定连接方式也具有多样，可以通过胶黏剂 50粘接或者紧固件44连接，详细描述可参见后述实施例。
可选地，摄像头本体11通过摄像头支架40与中框30固定连接，有两种方式：可以是在摄像头本体11与中框30连接之后，再通过摄像头支架40进一步加固；还可以是摄像头本体11与中框30并不相连，摄像头本体11只依靠摄像头支架40与中框30的连接关系。
可选地，摄像头支架40可以是个平板结构，或者是壳体结构，还或者是框架结构。
如图15所示，在本申请提供的一种实施例中，摄像头支架40具有外凸形成的收容壳41，摄像头本体11固定于收容壳41内。
如前所述，摄像头支架40可以是壳体结构，也就是如本实施例中，摄像头支架40具有外凸形成的收容壳41，收容壳41包围在摄像头本体11的外部。使得摄像头支架40能够更好地保护摄像头本体11，避免摄像头本体11在组装时被其他部件撞击而受损。
在本申请提供的一种实施例中，摄像头支架40的两端边沿具有内扣式翻边42，翻边42的内侧设置胶黏剂50用以将摄像头支架40与中框30粘接固定。
本实施例中的翻边42主要有两个作用：一是能够起到限位镜头12安装深度的作用，翻边42的高度能够决定镜头12伸入摄像头开孔21的深度，从而能够提高前置摄像头的组装精度；二是能够防止胶黏剂50向外溢出，翻边42将摄像头支架40与中框30之间支撑出了一定的空间，该空间能够容纳胶黏剂50，可以避免在将摄像头支架40与中框30进行按压时胶黏剂50从二者的间隙内挤压而溢出。
基于上述的翻边42的第二个作用，为了进一步防止胶黏剂50向外溢出，在本申请提供的一种实施例中，翻边42沿着摄像头支架40的端部边沿环绕半圈设置，以将胶黏剂50完全包围。
图16是本申请实施例提供的前置摄像头组装结构的一例的示意图。图17是图16中的前置摄像头组装结构的爆炸图。图18是图16中的前置摄像头组装结构的另一视角的爆炸图。图19是图16中B-B的剖视图。
如图16-图18所示，在本申请提供的一种实施例中，摄像头支架40与中框30仅通过紧固件44连接，具体为：摄像头支架40的两端开设有第一安装孔43，中框30开设有与第一安装孔43对应的第二安装孔33，第一安装孔43和第二安装孔33内设置紧固件44以将摄像头支架40与中框30固定连接。
如图19所示，在本申请提供的另一种实施例中，还可以在摄像头支架40与中框30粘接之后的基础上，再进一步通过紧固件44加固，具体为：摄像头支架40与中框30通过胶黏剂50粘接预固定后，在第一安装孔43和第二安装孔33内设置紧固件44以将摄像头支架40与中框30固定连接。
可选地，紧固件44可以是螺钉或者销钉。
具体地，紧固件44是螺钉，第二安装孔33的孔壁开设有与螺钉适配的螺纹，在螺钉旋合在第二安装孔33内时，螺钉的头部压紧在第一安装孔43的孔口处。
具体地，紧固件44是销钉，第二安装孔33与销钉过盈配合，在销钉插接在第二安装孔33内时，销钉的头部压紧在第一安装孔43的孔口处。
在本申请提供的一种实施例中，第一安装孔43的孔径大于第二安装孔33的孔径，以使得摄像头支架40相对于中框30具有调整余量。
本实施例中，由于第一安装孔43的孔径大于第二安装孔33的孔径，使得第一安装孔43相对于第二安装孔33能够在一定范围偏离，以使得在镜头12与摄像头开孔21进行对中调整时，摄像头支架40相对于中框30在水平方向具有一定的调整余量。
如图15和图19所示，在本申请提供的一种实施例中，摄像头本体11与中框30之间设置有弹性缓冲体35。
摄像头本体11与中框30之间设置有弹性缓冲体35，起到缓冲振动、防止镜头12撞伤的作用。同时，弹性缓冲体35还具有密封防尘作用，避免灰尘等进入摄像头内部而影响采光质量。
可选地，弹性缓冲体35可以是缓冲泡绵，也可以由其他柔软有弹性的材料制成。在其他实施例中，也可以不设弹性缓冲体35。
在本申请提供的一种实施例中，收容壳41为金属壳。
收容壳41除了用于保护摄像头本体11之外，在本实施例中，收容壳41为金属壳时，收容壳41还具有导热作用和屏蔽作用。
此外，收容壳41为金属壳时，可以通过磁吸式机械臂进行拾取和转移，有利于装配环节的操作。
可选地，金属壳的材质为不锈钢、洋白铜、镁铝合金等。
在本实施例中，金属壳具有一定的强度，可以有效避免摄像头本体11上的电子元件造成破坏，可以起到保护电子元件的作用。
在本申请提供的一种实施例中，收容壳41与摄像头本体11的间隙内填充有导热剂。
摄像头在工作的时候会产生热量，使设备内部温度迅速上升，为了将热量快速的传递出去，可以在收容壳41与摄像头本体11的间隙内填充有导热剂，以热传导的方式将热量传递到收容壳41，然后到达收容壳41的热量再通过中框30或者后盖将热量散发至环境中。导热剂可以有效填充收容壳41与摄像头本体11的间隙，能够降低热阻，提高摄像头本体11向收容壳41导热的能力，使热量的传导更加顺畅迅速。
可选地，导热剂可以是液态金属。具体地，金属材料可以为镓基合金、铟基合金或铋基合金。
前述实施例中，详细介绍了一类具有外凸收容壳41的摄像头支架40，在其他实施例中，对于摄像头支架40的结构还有其他设计方式，具体如下。
图20是本申请实施例提供的摄像头支架40的一例的示意图。图21是本申请实施例提供的前置摄像头组装结构的另一例的剖视图。
如图20和图21所示，在本申请提供的一种实施例中，摄像头支架40包括内凹形成的收容槽45，收容槽45的槽底壁开设有用于避让镜头12的避让孔46，摄像头本体11固定于收容槽45内，摄像头本体11的镜头12依次穿过避让孔46和孔道31后，伸入至摄像头开孔21内并对中设置，收容槽45的槽壁外侧固定于容置槽32内。
在本实施例中，通过摄像头支架40与中框30进行固定连接，以将摄像头本体11固定于容置槽32内，此种固定方式直接作用于摄像头支架40上，可以避免直接接触摄像头本体11，从而能够防止在固定过程中造成摄像头本体11的损坏，降低组装过程中的物损。
在本申请提供的一种实施例中，收容槽45的槽壁外侧尺寸小于容置槽32的尺寸，以使得摄像头支架40相对于中框30具有调整余量。
本实施例中，由于收容槽45的槽壁外侧尺寸小于容置槽32的尺寸，使得收容槽45可以在容置槽32内进行水平方向位移，从而使得在镜头12与摄像头开孔21进行对中调整时，摄像头支架40相对于中框30在水平方向具有一定的调整余量。
收容槽45的槽壁外侧固定于容置槽32内，有多种方式可以实现，比如可以通过摄像头支架40与中框30以紧固件44连接的方式实现，如图21所示，在本申请提供的一种实施例中，摄像头支架40的两端开设有第一安装孔43，中框30开设有与第一安装孔43对应的第二安装孔33，第一安装孔43和第二安装孔33内设置紧固件44以将摄像头支架40与中框30固定连接，此时收容槽45的槽壁外侧固定于容置槽32内。
还可以是，收容槽45的槽壁外侧通过胶黏剂50粘接固定于容置槽32内，如图21所示，在本申请提供的一种实施例中，收容槽45的槽壁外侧与容置槽32的槽壁之间填充胶黏剂50，以将二者粘接固定。
还可以是，同时使用胶黏剂50粘接和紧固件44连接。
其中，紧固件44与第二安装孔33的设计和前述实施例相似，在此不再赘述。
在本申请提供的一种实施例中，第一安装孔43的孔径大于第二安装孔33的孔径，以使得摄像头支架40相对于中框30具有调整余量。
图22是本申请实施例提供的摄像头本体11的一例的示意图。图23是本申请实施例提供的摄像头支架40的另一例的示意图。
如图20、图22和图23所示，在本申请提供的一种实施例中，摄像头支架40与摄像头本体11上设置有防呆机构47。
在将摄像头支架40与摄像头本体11进行组装时，能够提高组装效率和准确性。
本申请实施例还提供了一种电子设备，包括上述的组装结构。
该电子设备可以为图1所示的手机，与相关技术不同的是，手机的壳体60内设置的是本申请实施例提供的前置摄像头的组装结构。
此外，电子设备还可以为笔记本电脑、平板电脑、电子手表中的任意一种。
本申请实施例提供的电子设备，由于采用了上述的前置摄像头的组装结构，因此该电子设备的前置摄像头的镜头黑边70更小，屏占比更高，除此之外，对于零部件的尺寸精度以及安装精度也要求较低，总体降低了电子设备的加工及组装难度，同时也降低了生产制造成本。
最后应说明的是：以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何在本申请揭露的技术范围内的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
