Description

玻璃表面应力检测装置 技术领域
本发明涉及一种光学检测装置，尤其涉及一种对玻璃的表面应力进行检测的检测装置。
背景技术
玻璃是日常生活和工业生产中都常见的材料，诸如钢化玻璃作为被人们熟知的安全玻璃的一种，广泛应用在建筑、汽车、玻璃幕墙、家用玻璃制品等领域。对于钢化玻璃而言，为提高玻璃的强度，通常在制作过程中使用化学或物理的方法，在玻璃表面形成一定大小的压应力，玻璃承受外力时首先抵消表层应力，从而提高了承载能力。对于普通玻璃而言，由于加工过程中的各种工艺影响，玻璃板中也会残留应力，如果应力超出一定范围，则对玻璃的使用性能造成明显损失，构成缺陷，因此应力水平通常是衡量玻璃板质量的重要指标，涉及玻璃板的使用安全。
为获得这一指标，在国标等标准规定，采用双折射的方式测量玻璃的表面应力，以表征玻璃内部的应力水平。目前，在实际使用中，测定玻璃表面应力的方法可归纳为两种：微分表面折射法DSR(Differential Surface Refractometry)和表面掠角偏光法GASP(Grazing Angle Surface Polarimetry)。其中DSR方式由于使用的光学件较少，检测仪器的价格相对较低，被各种检测机构广为采用。现有的DSR方式玻璃表面应力检测仪体积较为庞大，大多依赖人工通过测微目镜对应力进行目测，然后根据公式计算出应力值，这样的方法显然受到测量者肉眼观测精度的限制，也不利于电子化的数据处理。
发明内容
本发明提供一种玻璃表面应力检测装置，通过提供遮光罩内的小 尺寸光学系统获取从待测玻璃表面返回的双折射光，配合电子照相用的图像捕获装置，可获得高精度的检测结果，避免了杂光的影响。
根据本发明的一种玻璃表面应力检测装置，包括遮光外罩，照明单元，检测棱镜和成像单元，所述照明单元、检测棱镜和成像单元均位于遮光外罩内部；其中，所述遮光外罩用以屏蔽外界杂散光对检测的影响并界定检测装置的外形尺寸；所述检测棱镜通过折射液与被检测玻璃的表面接触，使从所述照明单元射入检测棱镜的光能够在接触表面上全反射，从而在全反射后的光中引入包含玻璃双折射能力的信息，进入成像单元进行成像；所述成像单元包括至少两个反射镜，所述至少两个反射镜中的一个的位置可以由使用者进行调节。
进一步的，照明单元包括LED光源以及置于光源后光路上用于对光源出射光进行过滤的滤光器。
优选的，检测棱镜为方形棱镜，调节第一反射镜位置的方式为螺丝调节。
具体的，成像单元沿光路方向依次包括第一反射镜，透镜组，第二反射镜，分析镜和感光元件；第一反射镜为位置可以由使用者进行调节的反射镜。
感光元件为CCD，CMOS或PMT中的一种，分析镜为两片互相垂直的偏振片拼接或者采用一个或者多个偏振分光棱镜。
成像单元可进一步包括第三反射镜，沿光路方向上所述第三反射镜位于第二反射镜之后，且与第二反射镜的反射面相对。
第三反射镜可旋转，将分析镜位于所述第二反射镜与所述第三反射镜之间，所述成像单元进一步包括目视观察单元，所述目视观察单元与所述感光元件相对于所述第三反射镜共轭。
感光元件与数据处理单元电连接，所述数据处理单元为置于遮光外罩内的小型数据处理器，所述遮光外罩上具有显示单元，用以显示至少包括检测结果的图形图像界面。
根据本发明的玻璃碎片检测装置，由于使用了遮光外罩，避免了检测时杂散光的影响，又利用反射镜多次反射以缩短整体光路所占据的空间，仅调节一个反射镜的使用，降低了使用难度，实现了检测装 置的小型化，提高了检测质量。

具体实施方式
以下，参照附图对于本发明的实施例进行详细的说明。在以下的说明中，为便于理解和描述，相同的部件使用了相同的数字标号。
图1为根据本发明的玻璃表面应力检测装置示意图。如图1所示，本发明的玻璃表面应力检测装置100，包括遮光外罩1、照明单元2，检测棱镜3和成像单元4，遮光外罩用以屏蔽外界杂散光对检测的影响并界定检测装置的外形尺寸，照明光源、检测棱镜和成像单元均位于遮光外罩内部，其中检测棱镜通过折射液与被检测玻璃5的表面接触，以使由照明光源射入检测棱镜的光能够在检测棱镜与被检测玻璃的接触表面上全反射，从而在全反射后的光中引入包含玻璃双折射能力的信息，再进入成像单元进行成像。
为节能和供电电压的便利考虑，照明单元使用的光源21优选为LED光源，在光源出光口或临近出光口的光路附近使用诸如干涉滤光片22的滤光器对光源出射的光进行提纯，再射入检测棱镜3，为了减小装置的整体体积，在光源21检测棱镜之间设置反射镜23。检测棱镜3可以为三角棱镜、入射面为圆弧型的矩形棱镜和梯形棱镜等，优选的，检测棱镜3为方形棱镜。由于对光源出射的光进行了滤光，入射检测棱镜的光成为单色性好的光源，减少了检测光从玻璃-棱镜界面出射后光源光谱宽度对测量的不利影响。光源的入射角通过科学计算确定，配合相应参数的方形棱镜的使用，避免了操作人员在多个台阶 中选择而影响测量精度。
成像单元包括依光路依次设置的透镜组41、分析镜42和感光元件43，进一步的，成像单元还包括至少两个反射镜，如图1所示，成像单元包括第一反射镜a，第二反射镜b和第三反射镜c，其中第一反射镜a置于检测棱镜3和透镜组41之间，且临近检测棱镜，以将从检测棱镜3出射的光反射进入透镜组41；第二反射镜b和第三反射镜c的反射面相对设置，且均置于透镜组41和分析镜42之间，用以将由透镜组41聚焦的光导向分析镜42，再经由分析镜后射入诸如CCD/CMOS/PMT等的感光元件43成像，在感光元件上呈现出诸如图2的台阶差图像。进一步的，临近检测棱镜的第一反光镜的位置可以由使用者进行调节，从而调节进入透镜组41的光的角度，使得临界角度的光经过透镜组后照射到感光元件上，呈现高质量的台阶差图像，调节方式优选为螺丝d调节，以提高易用性和调节的精度。分析镜42可以采用两片互相垂直的偏振片拼接或者采用一个或者多个偏振分光棱镜实现。
与感光元件43电连接的数据处理单元(未图示)对台阶差图像进行处理，从而得到玻璃的表面应力。数据处理单元可以通过具有数据处理软件的通用计算机实现，或者使用专用的小型数据处理器实现，例如，单片机，FPGA，CPLD等，小型的数据处理器可以集成在感光元件43中，此时为了能够直观让使用者了解检测结果，在遮光外罩表面上或突出于外罩表面设置有显示单元44。如图3所示，显示单元44可以包括显示检测结果的图形图像界面，以及控制内置于检测装置内的小型数据处理器进行诸如初始化、清零、校准、故障检测等实体或虚拟按键，相应的，显示单元可以为触摸显示屏。
可选择的，第三反射镜c可以省略，或者第三反射镜c为可旋转的反射镜。对于第三发射镜为可旋转的反射镜时，如图4所示，成像装置还进一步包括目视观察单元45，此时所述分析镜42位于第二反射镜b与第三反射镜c之间的光路上，目视观察单元45与感光单元43相对于第三反射镜c共轭，用户可以选择将第三反射镜c旋转移出光路，从而以目视观察单元45观测并人工计算结果，或者以目视观察 单元45观测后将第三反射镜c旋转移入光路，使感光元件43进行图像记录实现电子测量，类似于DSLR相机的工作方式。当使用感光元件实现电子测量时，优选的，具备如图3所示实施例的内置小型数据处理器和外罩上的显示单元(图4中未图示)。
根据实施例的玻璃表面应力检测装置，使用了遮光罩单元避免了杂散光的影响，并通过使用反射镜缩短整体光路所占据的空间，实现了小型化，进一步的，通过将除第一反射镜之外的其它元件均固定安装，从而避免对多个元件的调节影响检测精度，降低了用户使用的难度，同时利用感光元件的记录获得不依赖于操作者目视操作技能的准确检测结果，实现了高精度的电子检测。
本发明不限于上述实施例，说明书中的各种实施方式仅用于进行说明，其并不对本发明的保护范围起到限定作用。在不脱离本发明范围的情况下，可以进行各种变形和修改。在本领域技术人员所具备的知识范围内，在本发明公开的实施方式基础上所做的任何省略、替换或修改将落入本发明的保护范围。
