技术领域
本申请属于电子产品技术领域，尤其涉及一种贴合设备校正装置、贴合设备校正方法及显示面板贴合设备。
背景技术

因此，亟需一种新的贴合设备校正装置、贴合设备校正方法及显示面板贴合设备。

具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例，为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。应理解，此处所描述的具体实施例仅意在解释本申请，而不是限定本申请。对于本领域技术人员来说，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请更好的理解。
为了更好地理解本申请，下面结合图1至图4根据本申请实施例的贴合设备校正装置、贴合设备校正方法及显示面板贴合设备进行详细描述。
图1示出了根据本申请实施例的一种贴合设备校正装置的结构示意图。如图1所示，根据本申请实施例的贴合设备校正装置包括治具组件及图像获取组件3。治具组件包括相互配合使用的第一治具1和第二治具2。第一治具1上设置有第一对位标识。第二治具2上设置有第二对位标识。第一治具1与第二治具2通过第一对位标识和第二对位标识进行对位。图像获取组件3，用于分别获取第一治具1的第一对位标识的表面的第一图像和第二治具2的第二对位标识的表面的第二图像；根据第一图像和第二图像获得第一对位标识和第二对位标识的对位参数，以校正贴合设备。
本申请实施例提供的贴合设备校正装置包括治具组件、图像获取组件3。治具组件包括相互配合使用的第一治具1和第二治具2，用于等效底座组件，即用于替代显示面板贴合设备中的底座组件进行定位校正。通过图像获取组件3分别获取第一治具1的第一对位标识的表面的第一图像和第二治具2的第二对位标识的表面的第二图像。根据第一图像和第二图像能够获得第一对位标识和第二对位标识的对位参数，使第一对位标识和第二对位标识进行对准，实现第一治具1和第二治具2之间的对位。而第一治具1和第二治具2完成对位即等效于底座组件完成了对位，以校正显示面板贴合设备。
相比于通过定位销进行定位固定的底座组件，在底座组件安装后，只能通过实际贴合时进行多次贴合实验来计算贴合的误差。根据计算出的贴合误差，调整定位销孔的螺纹间隙以实现底座组件的中心对齐，进而实现盖板和贴合压头的对齐。由于显示模组由贴合压头支撑，从而实现显示模组准确贴合到盖板上。但是，多次试验过程复杂繁琐，并且精度误差较大，影响贴合精度。特别是，由于底座组件除了定位销孔位置，其余位置的加工精度相对较低，直接用相机拍摄也无法对定位基点进行定位。
本申请提供的实施例中额外采用具有对位标识的治具组件进行对位，只需一次对位调整，对位过程更加快速、准确，从而提高了效率。而且，本申请的贴合设备校正装置能够保证用底座组件替换治具组件后，底座组件之间的对位精度，避免影响后续的显示模组与盖板的贴合精度，提高了贴合良率。
需要说明的是，根据第一图像和第二图像获得第一对位标识和第二对位标识的对位参数，以校正贴合设备的操作，可以是工作人员获取了第一图像和第二图像进行计算得到对位参数，然后根据对位参数进行手动调节或者输入至贴合设备的执行装置进行自动调节对位校正；还可以是第一图像和第二图像通过校正装置的传输模块传输至贴合设备的后台运算装置进行处理得到对位参数，通过贴合设备自身的控制器以及位移平台完成；也可以通过手动调整的方式进行操作对位校正；还可以在校正装置自身有处理芯片等在本地对第一图像和第二图像进行处理得到对位参数之后，在手 动或自动调节对位校正。
在一些可选的实施例中，第一治具1包括等效底座组件中的贴合件底座6的第一平面，第一对位标识设于第一平面。第二治具2包括等效底座组件中的显示模组底座7的第二平面，第二对位标识设于第二平面。
需要说明的是，为了提高第一治具1和第二治具2对位的精度，第一平面和第二平面通常为轴对称或者中心对称图形，例如矩形、梯形等，以将贴合件底座6和显示模组底座7不规则的立体形状等效为方便确定中心的、规则的平面图形。
为了方便对位，第一对位标识和第二对位标识采用中心点和第一平面和第二平面的中心点重合的图形，具体可以采用十字形、标识出圆心的圆形等形状。例如，当第一平面和第二平面均为矩形平面时，第一对位标识和第二对位标识为过矩形平面的相对边的中点形成的十字线。当然，第一对位标识和第二对位标识也可以为由矩形平面的两条对角线形成的X形标识。为了便于拍摄识别，第一对位标识和第二对位标识具体可以通过加工凹槽的形式制作，其位置精度<±5μm，贴合件通常为玻璃盖板，贴合时盖板置于贴合件底座。显示模组底座用于支撑贴合压头，进而支撑显示模组，在曲面盖板和显示模组的贴合过程中，贴合压头通常为采用硅胶等兼具柔性和一定硬度的可变形仿形压头。
在一些可选的实施例中，校正装置进一步包括：第一位移平台4，被配置为用于装配并带动第一治具1和第二治具2中的至少一者进行对位。处理模块，处理模块处理图像获得第一对位标识和第二对位标识的对位参数，并根据对位参数调节第一位移平台4，使第一对位标识和第二对位标识进行对准。可选的，第一位移平台4的位移精度误差小于或等于3μm。
其中，第一位移平台4，被配置为用于装配并带动第一治具1和第二治具2中的至少一者进行对位。具体是指，第一位移平台4可以只与第一治具1和第二治具2中的一者装配连接，只带动与第一位移平台4具有装配关系的一者移动，也可以同时与第一治具1和第二治具2两者连接，带动第一治具1和第二治具2移动。
使用时，在图像获取组件分别获取第一治具1的第一对位标识的表面 的第一图像和第二治具2的第二对位标识的表面的第二图像后，处理第一图像和第二图像以获取第一对位标识和第二对位标识的对位参数。之后根据对位参数调节第一位移平台4，使第一对位标识和第二对位标识进行对准，实现第一治具1和第二治具2之间的对位。
为了获取第一对位标识和第二对位标识的第一图像和第二图像，在一些可选的实施例中，图像获取组件3至少包括两个拍摄方向分别朝向第一对位标识和第二对位标识所在方向的图像获取单元。
由于采用至少两个分别朝向第一对位标识和第二对位标识所在方向的图像获取单元进行拍摄，为了保证之后图像处理的准确性，一般需要将各个图像获取单元沿同一直线设置，即保证图像获取单元的拍摄位置的对位，以使拍摄出来的第一对位标识和第二对位标识的第一图像和第二图像之间的位置受到图像获取单元之间的对位参数影响。
为了对图像获取单元进行对位调整，在一些可选的实施例中，还包括第二位移平台5，第二位移平台5上设有两个图像获取单元，第二位移平台5被配置为用于装配并带动两个图像获取单元中的至少一者进行对位。
具体的，第二位移平台5包括两个固定臂，分别固定两个图像获取单元，两个图像获取单元上下设置，通过两个固定臂调整图像获取单元的相对位置，以使两个图像获取单元的拍摄中心相对于治具组件位于同一直线上。图像获取单元具体可以采用工业相机，工业相机相比于民用相机(摄像机)而言，具有高的图像稳定性、高传输能力和高抗干扰能力等。
为了保证对位精度，在一些可选的实施例中，第一位移平台4的位移精度误差小于或等于3μm；第二位移平台5的位移精度误差小于或等于5μm。其中，3μm、5μm均指位移精度误差的绝对值，即根据移动方向以及基准不同，3μm、5μm可能为正值或者负值。
可选的，还包括第三位移平台，第三位移平台被配置为用于装配并带动第一治具1和第二治具2进行相向移动。通过第三位移平台带动第一治具1和第二治具2进行相向移动，以实现第一治具1和第二治具2在第三方向Z上的对位。贴合件贴合于显示模组时，两者在第三方向Z上的相对位置也是需要进行对位的，如果对位不正，可能会出现贴合件与显示模组 之间的相互作用力过大，而导致贴合件或显示模组受损。因而可以通过第一治具1和第二治具2在第三方向Z上预对位，并通过第三位移平台对第一治具1和第二治具2的相对位置进行调整，第三位移平台可以采用以伺服电机为动力的平台。
具体的，第一位移平台4和第二位移平台5可以采用UVW平台或XYθ平台中的一种，由上板，下板和四个单体组组成。UVW对应的是三个动力轴，X轴方向两个马达(VW轴)，Y轴方向一个马达(U)，X轴两个马达同动实现X轴移动，Y轴一个马达控制Y轴移动，X轴两个不同步的时候实现θ轴转动。这样，通过控制三个马达实现了X，Y方向的移动以及θ轴旋转实现对位。XYθ平台与UVW平台的结构虽有不同，但都是通过X轴移动，Y轴移动，θ轴旋转，实现对位功能，用户可以根据实际需要进行选择。本申请还提供一种贴合设备校正方法。图2示出了本申请的贴合设备校正方法的实施例的流程示意图。如图2所示，根据本申请实施例的贴合设备校正方法包括：
S110：将第一治具1安装于显示面板贴合设备上的贴合件底座6的安装位，将第二治具2安装于显示面板贴合设备上的显示模组底座7的安装位；
S120：通过图像获取组件3分别获取第一治具1的第一对位标识的表面的第一图像和第二治具2的第二对位标识的表面的第二图像；
S130：处理第一图像及第二图像以获取第一对位标识和第二对位标识的对位参数；
S140：根据对位参数带动治具组件移动，使第一对位标识和第二对位标识进行对准，以实现显示面板贴合设备校正。
在S110的步骤中，治具组件中的第一治具1和第二治具2需要代替底座组件进行定位，因而先将第一治具1和第二治具2分别固定在用于固定底座组件的安装位上，即将第一治具1和第二治具2分别等效为底座组件中的贴合件底座6和显示模组底座7进行定位。
在S120的步骤中，一般通过图像获取组件3例如工业相机分别获取第一治具1的第一对位标识的表面的第一图像和第二治具2的第二对位标识 的表面的第二图像。
在S130的步骤中，在S120的步骤中，可以通过halcon等软件进行图像处理。
在S140的步骤中，根据对位参数控制第一位移平台4带动治具组件移动，使第一对位标识和第二对位标识进行对准，保证第一治具1和第二治具2之间的对位精度，进而实现底座组件之间的精准快速对位。
在一些可选的实施例中，为了实现第一对位标识和第二对位标识的对准，在处理第一图像及第二图像以获取第一对位标识和第二对位标识的对位参数的步骤中：对位参数包括第一对位标识和第二对位标识在同一平面内的位移差值参数以及角度差值参数。
位移差值参数包括第一对位标识和第二对位标识在第一方向X上的距离参数以及在垂直于第一方向X的第二方向Y上的距离参数。角度差值参数即完成位移差值参数校正后第一对位标识或第二对位标识可根据角度差值参数转动相应角度，以使第一对位标识或第二对位标识重合。
由于部分产品的贴合件为非对称结构，一般是指玻璃盖板为非对称结构，贴合件与治具组件中对应的治具的中心会存在偏距，导致实际贴合存在较大的误差。显示模组与治具组件中对应的治具的中心也可能存在偏距，且由于贴合件和显示模组分别固定在贴合件底座6和显示模组底座7上，因而贴合件底座6和显示模组底座7与治具组件之间也会存在一定的偏距；在实际调机时需要补偿上述偏距，从而保证贴合良率。在一些可选的实施例中，还包括获取贴合件底座6与第一治具1之间的中心误差偏移参数以及显示模组底座7与第二治具2之间的中心误差偏移参数，对对位参数进行校准。具体可以根据中心误差偏移参数带动治具组件移动，消除底座组件与治具组件之间的中心误差。
本申请还提供一种显示面板贴合设备。图3示出了本申请的显示面板贴合设备的实施例的结构示意图。如图3所示，根据本申请实施例的显示面板贴合设备包括：底座组件，包括用于安装待贴合件的贴合件底座6和用于安装待贴合显示模组的显示模组底座7；第一支架8，具有贴合件底座安装位；第二支架9，具有显示模组底座安装位；校正装置，为根据上述 第一方面的任一实施例的校正装置，第一治具1安装于第一支架8的贴合件底座安装位，第二治具2安装于第二支架9的显示模组底座安装位。
第一支架8上的贴合件底座安装位既可以安装贴合件底座，也可以安装第一治具，即贴合件底座6、第一治具分别与第一支架8之间可拆卸连接。同理，第二支架9上的显示模组底座安装位既可以安装显示模组底座，也可以安装第二治具。
在一些可选的实施例中，显示面板贴合设备还包括第一位移平台4，连接于第一支架8及第二支架9中的至少一者，对第一支架8及第二支架9中的至少一者提供三维空间的位移；处理装置，处理第一图像和第二图像获得第一对位标识和第二对位标识的对位参数，并根据对位参数调节第一位移平台4，使第一对位标识和第二对位标识进行对准；可选的，第一位移平台4的位移精度误差小于或等于3μm。
其中，对第一支架8及第二支架9中的至少一者提供三维空间的位移具体是指，第一位移平台4可以带动第一支架8及第二支架9中的至少一者在水平面内移动，以实现显示面板贴合设备的对准校正。第一位移平台4还可以带动第一支架8及第二支架9中的至少一者在竖直面内移动，以实现贴合件和显示面板的贴合工艺。
本申请还提供一种基于上述的显示面板贴合设备的显示面板贴合方法。图4示出了本申请的显示面板贴合方法的实施例的流程示意图。根据本申请的实施例的显示面板贴合方法包括：
S210：将第一治具1安装于第一支架8的贴合件底座安装位，将第二治具2安装于第二支架9的显示模组底座安装位；
S220：通过图像获取组件3分别获取第一治具1的第一对位标识的表面的第一图像和第二治具2的第二对位标识的表面的第二图像；
S230：处理第一图像及第二图像以获取第一对位标识和第二对位标识的对位参数；
S240：根据对位参数带动治具组件移动，使第一对位标识和第二对位标识进行对准，以实现显示面板贴合设备校正；
S250：将第一治具1和第二治具2分别更换为底座组件中的贴合件底 座6和显示模组底座7；
S260：将贴合件和显示模组分别对应固定于贴合件底座6和显示模组底座7；
S270：对贴合件和显示模组进行贴合。
需要说明的是，当第一治具1和第二治具2完成等效对位后，需要将第一治具1和第二治具2拆下，换上贴合件底座6和显示模组底座7，因而需要将第一治具1和第二治具2分别与第一支架8及第二支架9可拆卸连接，方便进行替换，进行后续的贴合工艺。为了实现可拆卸式连接，具体可以通过定位销、卡爪、台钳等设备进行固定，只要能够方便第一治具1和第二治具2拆装且保证固定稳定性及精度的可拆卸式连接方式均可应用于本申请所提供的技术方案中。
可选的，第一治具和第二治具的加工精度误差<10μm，第一位移平台4和第二位移平台5的位移精误差<3μm，图像获取组件的安装精度误差<5μm，以使显示面板贴合设备、贴合设备校正装置整体校正精度误差＜50μm，中心对正精度高。
本申请实施例提供的一种显示面板贴合设备的贴合方法，能够将具有曲面或者非规则形状的底座组件之间的校正对位等效为具有规则、平面的对位标识的治具组件的对位。即先对治具组件进行对位，之后将第一治具1和第二治具2分别更换为底座组件中的贴合件底座6和显示模组底座7，能够对应于不同产品时显示面板及贴合件的更换，具有快速性，准确性，提高贴合良率。具体的，经过实验，本申请提供的技术方案相较于现有技术，贴合黑斑率降低10％，调机时间降低30％，且具有对非对称的贴合件的兼容性。
依照本申请如上文所述的实施例，这些实施例并没有详尽叙述所有的细节，也不限制该申请仅为所述的具体实施例。显然，根据以上描述，可作很多的修改和变化。本说明书选取并具体描述这些实施例，是为了更好地解释本申请的原理和实际应用，从而使所属技术领域技术人员能很好地利用本申请以及在本申请基础上的修改使用。本申请仅受权利要求书及其全部范围和等效物的限制。
