 本发明的实施方式
为使本实用新型的上述目的、特征和优点能够更加明显易懂，下面结合附图对本实用新型的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本实用新型。但是本实用新型能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本实用新型内涵的情况下做类似改进，因此本实用新型不受下面公开的具体实施例的限制。
参阅图1和图2，本实用新型一实施例提供的影像采集装置，包括从上至下依次设置的成像相机10、镜头20及光源30。成像相机10与镜头20同轴设置，使经镜头20的光线能够聚焦于成像相机10的感光芯片。影像采集装置还包括驱动机构40，驱动机构40预设有移动点位，驱动机构40驱动成像相机10及镜头20在纵向进行点位移动，使成像相机10在移动点位进行影像采集。
需要说明的是，驱动机构40设置移动点位的位置，驱动机构40便可根据点位移动信号自动驱动成像相机10及镜头20运动至相应的移动点位，以使成像相机10在该移动点位采集清晰的影像。即可理解为，上述的移动点位为可清晰成像的检测位置，该移动点位可以根据不同产品进行调整的，以便达到检测不同产品的目的。
上述影像采集装置，从上至下依次设置成像相机10、镜头20及光源30。需要检测待测产品的外观性能时，将待测产品放置于镜头20的下方。驱动机构40根据预设的点位移动信号驱动成像相机10及镜头20运动至相应的移动点位，并打开光源30，光源30发出的光照射在待测产品，光线经折射或反射后穿过镜头20，并在成像相机10进行成像，实现待测产品的影像采集。通过在影像采集装置设置驱动机构40，驱动机构40根据点位移动信号驱动成像相机10及镜头20运动至相应的移动点位，对待测产品进行影像采集，这样该影像采集装置具有多种成像效果，可取代传统的单站单张图片采集的方式，能够极大节省空间，提高视觉模块的利用率。并且，节省硬件成本，使检测成本低。
在一个实施例中，参阅图1和图2，驱动机构40包括伺服电机41及丝杆模组42。丝杆模组42设于伺服电机41的动力输出轴，成像相机10及镜头20连接于丝杆模组42。需要检测待测产品的外观性能时，启动伺服电机41，伺服电机41根据点位移动信号驱动丝杆模组42运动，进而带动成像相机10及镜头20运动至相应的移动点位，在移动点位来采集待测产品的影像。将伺服电机41及丝杆模组42作为驱动动力源，来驱动成像相机10及镜头20进行点位移动，这样可增加镜头20点位移动的精度及准确性。
需要说明的是，相比于步进电机，伺服电机41能够通过信号反馈来调整输入信号，从而快速精确地使镜头20在纵向进行移动。而且，伺服电机41信号的抗干扰能力、稳定性、响应速度及适应载荷急骤变化能力强，故伺服电机41能提供更高的精度及更好的稳定性，如此便可增加镜头20点位移动的精度及准确性。
具体地，使用如上所述的驱动机构40，镜头20纵向可移动范围为54mm。影像采集过程中，相邻影像点位移动耗时可达到30ms，重复定位精度可达0.003mm。
当然，在其它实施例中，驱动机构40也可为气缸、液压缸、同步带轮组件等。只要驱动机构40能够驱动成像相机10及镜头20在纵向进行点位移动即可，在此不再详述。
在一个实施例中，参阅图1和图2，影像采集装置还包括载板50。载板50连接于驱动机构40的运动部件，成像相机10及镜头20设于载板50。可以理解的是，驱动机构40的运动部件是指驱动机构40中能够纵向移动的部件，例如在上述的驱动机构40中，丝杆模组42的丝杆螺母即为运动部件。通过设置载板50，载板50可提供一个较大的安装面，便于安装成像相机10及镜头20。
进一步地，载板50可拆卸地连接于驱动机构40的运动部件。具体地，载板50通过螺钉等可拆卸地安装在驱动机构40的运动部件。如此，便于拆卸更换不同的载板50，使用方便且灵活。当然，在其它实施例中，载板50也可固定在驱动机构40的运动部件，例如载板50焊接在驱动机构40的运动部件，不以此为限。
在一个实施例中，参阅图1和图2，影像采集装置还包括用于固定镜头20的稳固件60。稳固件60设于载板50，且对应镜头20设置。通过设置稳固件60，稳固件60可加强镜头20的固定，降低运动过程中震动对成像质量的影像，保证移动过程中影像采集的稳定性。
进一步地，稳固件60可拆卸地连接于载板50。具体地，稳固件60通过螺钉等安装在载板50。如此，便于根据检测需求调整稳固件60的安装位置，进而调整镜头20所在的位置，使用方便且灵活。
在一个实施例中，参阅图1和图2，稳固件60为固定箍。具体地，固定箍包括第一箍块61及用于连接载板50的第二箍块62，第一箍块61具有半圆形凹槽，第二箍块62远离载板50的侧部对应具有半圆形凹槽，且第一箍块61及第二箍块62对合连接。安装该镜头20时，打开或拆下第一箍块61，将镜头20的一侧贴合于第二箍块62的半圆形凹槽的槽壁，再闭合或安装第一箍块61，使镜头20的另一侧贴合于第一箍块61的半圆形凹槽的槽壁，如此便可将镜头20安装在稳固件60，实现镜头20的加强固定。
具体地，参阅图1和图2，第一箍块61与第二箍块62之间可开合连接。例如，第一箍块61的一端与第二箍块62具有半圆形凹槽的一侧铰接，第一箍块61的另一端与第二箍块62具有半圆形凹槽的另一侧设有相互配合的止销孔或螺纹孔。或者，第一箍块61与第二箍块62之间可拆卸连接。例如，第一箍块61的一端与第二箍块62具有半圆形凹槽的一侧设有相互配合的第一止销孔或第一螺纹孔，第一箍块61的另一端与第二箍块62具有半圆形凹槽的另一侧设有相互配合的第二止销孔或第二螺纹孔。
进一步地，第一箍块61及第二箍块62的半圆形凹槽的槽壁设有防滑垫。具体地，防滑垫为橡胶垫、硅胶垫等。通过设置防滑垫，防滑垫可起到防滑的作用，增加镜头20外表面与第一箍块61及第二箍块62的摩擦力，从而进一步加强镜头20的固定，降低运动过程中震动对成像质量的影像，有效地保证移动过程中影像采集的稳定性。
在一个实施例中，参阅图3，图3示出了图1所示的影像采集装置的结构分解图。影像采集装置还包括第一固定件及第一连接板70。第一连接板70纵向设有第一导向条孔71，载板50对应设有第一固定孔51，第一固定件穿设在第一导向条孔71及第一固定孔51。影像采集装置还包括第二固定件及第一安装板72，第一安装板72设于第一连接板70远离载板50的一侧，第一安装板72的横向及纵向设有多个间隔设置的第二固定孔721，第二固定件穿设于第二固定孔721。如此，一方面，可配合稳固件60设置，使成像相机10及镜头20同轴设置，便于光经镜头20聚焦于成像相机10的感光芯片；另一方面，可根据检测需求，调整成像相机10的安装位置。
在一个实施例中，参阅图1和图2，光源30包括第一环形光源31及第二环形光源32。第一环形光源31设于载板50，第一环形光源31靠近镜头20且与镜头20同轴设置，第二环形光源32设于第一环形光源31远离镜头20的一侧且与第一环形光源31同轴设置。需要对待测产品进行影像采集时，将待测产品放置在第一环形光源31及第二环形光源32之间的位置，第一环形光源31发出的光从待测产品的顶部照射在待测产品上，经反射后，穿过镜头20并在成像相机10的感光芯片上成像，这样可使待测产品的异物、白亮点、黑点等缺陷清晰成像。第二环形光源32发出的光从待测产品的底部往上照射在待测产品上，经折射后，穿过镜头20并在成像相机10的感光芯片上成像，如此可使待测产品划伤痕、脱模等缺陷清晰成像。如此，可更全面地采集待测产品的外观缺陷，保证外观检测的全面性。
需要说明的是，在实际使用时，驱动机构40根据点位移动信号驱动成像相机10及镜头20运动至不同的移动点位，来选择性开启第一环形光源31和/或第二环形光源32，来更好地采集待测产品的外观缺陷。
在一个实施例中，待测产品为非球面塑料产品等，采用75°的第一环形光源31和75°的第二环形光源32。需要说明的是，75°的第一环形光源31及75°的第二环形光源32是指光源30中灯珠的发光方向光源30与水平方向的夹角为75°。镜头20镜头20在其他实施例中，该影像采集装置还可对其它类型的产品进行外观检测，例如非球面玻璃产品，球面塑料产品和球面玻璃产品等。
在一个实施例中，参阅图3和图4，图4示出了图3所示的影像采集装置在A处的结构分解图。影像采集装置还包括第一紧固件及第二连接板80。第二连接板80纵向设有第一条形孔81，载板50对应设有第一安装孔52，第一紧固件穿设于第一条形孔81及第一安装孔52。影像采集装置还包括第二紧固件、第三紧固件及横向设置的第二安装板82，第二安装板82设有透光孔821，第一环形光源31设于第二安装板82的底部，且第一环形光源31与透光孔821相对应。第二安装板82沿其长度方向设有第二条形孔822，第二连接板80对应设有第二安装孔，第二紧固件穿设于第二条形孔822及第二安装孔。第二安装板82沿其宽度方向设有第三条形孔823，第一环形光源31对应设有第三安装孔311，第三紧固件穿设于第三条形孔823及第三安装孔311。如此，可根据成像相机10及镜头20的位置，在XYZ三个维度方向调整第一环形光源31的位置，直至将第一环形光源31调整到合适的打光位置。
可以理解的是，第二安装板82的长度方向是指第二安装板82与第二连接板80连接的一边，第二安装板82的宽度方向是指第二安装板82与第二连接板80垂直的一边。
需要说明的是，参阅图3和图4，移动第二连接板80，使载板50的第一安装孔52对应于第二连接板80的第一条形孔81的不同位置，可实现第一环形光源31在Z轴方向位置的调整。移动第二安装板82，使第二连接板80的第二安装孔对应于第二安装板82的第二条形孔822的不同位置，可实现第一环形光源31在Y轴方向位置的调整。移动第一环形光源31，使第一环形光源31的第三安装孔311对应于第二安装板82的第三条形孔823的不同位置，实现第一环形光源31在X轴方向位置的调整。
当然，在其它实施例中，也可在载板50设置条形孔，在第二连接板80设置安装孔；或者，载板50及第二连接板80均设置条形孔；或者，沿载板50的高度方向间隔设置多个安装孔，沿第二连接板80的高度方向也对应间隔设置多个安装孔。另外，第二连接板80、第二安装板82及第一环形光源31中也可采用上述的替换方案。
在一个实施例中，参阅图3和图5，图5示出了图3所示的影像采集装置在B处的结构分解图。影像采集装置还包括机架90、第四紧固件及横向设置的第三连接板92。机架90纵向设有第四条形孔91，第三连接板92的侧部对应设有第四安装孔，第四紧固件穿设于第四条形孔91及第四安装孔。影像采集装置还包括第五紧固件、第六紧固件及横向设于第三连接板92的第三安装板93，第二环形光源32设于第三安装板93的顶部。第三连接板92设有第五条形孔921，第三安装板93对应设有第五安装孔931，第五紧固件穿设于第五条形孔921及第五安装孔931。第三安装板93设有第六条形孔932，第二环形光源32对应设有第六安装孔321，第六紧固件穿设在第六条形孔932及第六安装孔321。如此，可根据成像相机10及镜头20的位置，在XYZ三个维度方向调整第二环形光源32的位置，直至将第二环形光源32调整到合适的打光位置。
需要说明的是，参阅图3和图5，移动第三连接板92，使第三连接板92的第四安装孔对应于机架90的第四条形孔91的不同位置，可实现第二环形光源32在Z轴方向位置的调整。移动第三安装板93，使第三安装板93的第五安装孔931对应于第三连接板92的第五条形孔921的不同位置，可实现第二环形光源32在X轴方向位置的调整。移动第二环形光源32，使第二环形光源32的第六安装孔321对应于第三安装板93的第六条形孔932的不同位置，实现第二环形光源32在Y轴方向位置的调整。
当然，在其它实施例中，也可在机架90设置安装孔，在第三连接板92设置条形孔；或者，机架90及第三连接板92均设置条形孔；或者，沿机架90的高度方向间隔设置多个安装孔，沿第三连接板92的高度方向也对应间隔设置多个安装孔。另外，第三连接板92、第三安装板93及第二环形光源32中也可采用上述的替换方案。
在一个实施例中，参阅图1和图2，成像相机10固定连接于镜头20的顶部。如此，可减小运行过程中带来的不稳定性。
在一个实施例中，镜头20为双远心镜头20。需要说明的是，双远心镜头20的远心度小，分辨率高，近乎零失真度；物方及像方双远心设置，光投射率高；在景深范围内，无放大倍率的变化。如此，采用低景深高分辨率的双远心镜头20，能够保证小尺寸物品或者较小的缺陷能够成像清晰，从而保证待测产品外观性能检测的准确性。
在一个实施例中，成像相机10为CMOS全局曝光相机。如此，采用CMOS全局曝光相机进行影像采集，能够保证既快速又稳定地获得待测产品的影像。
