具体实施方式
以下结合附图对本公开的原理和特征进行描述，所举实例只用于解释本公开，并非用于限定本公开的范围。
针对相关技术中触摸屏等贴合元件在进行贴合强度测试时所采用的测试治具通用性差的技术问题，本公开提供了一种贴合强度测试治具，其能够对不同尺寸产品贴合强度进行测试。
本公开实施例中所提供的一种贴合强度测试治具，用于对贴合元件进行贴合强度测试，所述贴合元件包括贴合一起的第一部件和第二部件。
如图1和图2所示，所述贴合强度测试治具包括多个调节杆100，多个所述调节杆100顺次首尾连接，并在调节杆100内侧围设形成用于容置所述贴合部件的容纳空间10；其中，每一个所述调节杆100均包括杆体110和滑块120，所述滑块120位于所述杆体110的一端，每一个所述调节杆100的滑块120均能够在与该调节杆连接的另一个调节杆100的杆体110上滑动，以调节所述容纳空间10的大小。
本公开的贴合强度测试治具中的多个调节杆100可以围设成一与待测试贴合元件(如：触摸屏)形状对应的容纳空间10，且由于每一调节杆100的端部的滑块120可以在与之连接的另一个调节杆100的杆体110上滑动，多个调节杆100之间可以通过滑块120与杆体110的配合，根据待测试贴合元件的大小进行不同尺寸连续可调节，而改变所述容纳空间10的大小，从而能 够针对不同型号的贴合元件进行贴合强度测试，操作方便，尤其是，当本公开所提供的贴合强度测试治具应用于触摸屏贴合强度测试时，可以实现对不同尺寸产品贴合强度进行测试的目的，从而解决了不同型号的触摸屏的贴合强度测试需要专门测试治具的技术问题，对相关技术中的测试治具普适性差的问题进行改进，填补了该类测试用通用治具的空白。
需要说明的是，本公开所提供的贴合强度测试治具其可以应用于各种贴合元件的贴合强度治具，尤其是，可以用于触摸屏的贴合强度测试，以下仅以所述贴合测试治具用于测试触摸屏的贴合强度为例，来对本公开实施例中所提供的贴合强度测试治具进行更为详细的说明。
其中需要说明的是，所述贴合强度测试治具用于触摸屏贴合强度测试时，通常，采用治具固定触摸屏的显示模块，即，所述第一部件通常是指触摸屏的显示模块，例如液晶显示模块。所述第二部件通常是指触摸屏的触控面板，当然，在实际应用中，并不以此对本公开进行限定。
在本公开所提供的实施例中，可选的，如图1所示，所述多个调节杆100有四个，分别为第一调节杆100a、第二调节杆100b、第三调节杆100c和第四调节杆100d，其中第一调节杆100a上的滑块120可移动地连接于第二调节杆100b上的杆体上；第二调节杆100b上的滑块120可移动地连接于第三调节杆100c上的杆体上；第三调节杆100c上的滑块120可移动地连接在第四调节杆100d上的杆体上；第四调节杆100d上的滑块120可移动地连接在第一调节杆100a上的杆体上。
当然可以理解的是，在实际应用中，所述调节杆100的具体数量可以根据实际需求而进行调整。
图2表示本公开实施例中提供的贴合强度测试治具的调节杆的放大示意图。图3为图2中调节杆的另一角度的示意图。图4为图2中调节杆的俯视图。图5为图2中调节杆的杆体的横截面结构示意图。
如图2至图5所示，在本公开所提供的实施例中，可选的，每一个所述调节杆100的滑块120上均具有一中空部120a，与该调节杆连接的另一调节杆100的杆体110容置于所述中空部120a内。
在上述方案中，多个调节杆100之间的滑块120与杆体110之间的配合 方式是通过将每一调节杆100的滑块120的中空部120a内部容置有与之连接的另一调节杆100的杆体110，实现滑块120与杆体110之间的连接，结构简单，可以根据触摸屏的尺寸大小移动滑块120，来实现对于多个滑动杆围设成的容纳空间10大小调节。
此外，如图1至图5所示，在本公开所提供的实施例中，可选的，所述滑块120为一中空的框架结构，每一个所述调节杆100的滑块120能够套设在与该调节杆连接的另一个调节杆100的杆体110上。
采用上述方案，所述滑块120设计为中空的框架结构，可选的，如图2所示，所述滑块120为一闭合环状框架结构，如：矩形框结构等，通过将所述滑块120套设在杆体110上来实现滑动连接，这种配合方式更为牢靠。
应当理解的是，在实际应用中，所述滑块120还可以设计为其他结构，只需要所述滑块120上设计有中空部120a即可，例如：所述滑块120为半环状框架结构等。但是需要说明的是，将所述滑块120设计为中空的闭合环状框架结构与将所述滑块120设计为半环状框架结构相比，滑块120更不易脱离杆体110，也更有利于整体治具结构稳定性。
在本公开所提供的实施例中，可选的，如图2至图5所示，在每一个所述调节杆100的杆体110的侧面上具有沿所述杆体110的轴向方向延伸的凹槽111，在每一个所述调节杆100的滑块120的围成所述中空部120a的内壁上设置有一凸起块121；其中，每一个所述调节杆的滑块120上的凸起块121卡装入与该调节杆连接的另一个调节杆100的凹槽111内，并能够在与该调节杆连接的另一个调节杆100的凹槽111内滑动。
采用上述方案，通过在调节杆100的杆体110上设置凹槽111，在所述滑块120的围成所述中空部120a的内壁上设置凸起块121，通过所述凹槽111和所述凸起块121的配合，可以使得滑块120在杆体110上滑动时，更为稳定、顺滑，提高了治具的稳定性。
需要说明的是，所述凹槽111可选的设置在所述杆体110的外侧，所述外侧是所述杆体110的形成所述容纳空间的内侧相对的一侧，相应的，所述凸起块121设置在与所述外侧对应的所述滑块120的围成所述中空部120a的内壁上。应当理解的是，所述凸起块121和所述凹槽111的具体设置位置并 不进行限定。
此外，在本公开所提供的实施例中，可选的，如图2至图5所示，所述凸起块121为横截面呈梯形的块状结构，且其朝向所述凹槽111的一端端面面积小于其与所述滑块120连接的一端端面面积；所述凹槽111为与所述凸起块121结构匹配的、横截面为梯形的梯形凹槽结构。
采用上述方案，将所述凸起块121设计为梯形结构，所述凹槽111设计为与所述凸起块121结构配合的倒梯形结构，两者相互配合，能够加强结构的稳定性，滑块120滑动更为顺滑。当然可以理解的是，对于所述凸起块121及所述凹槽111的具体结构并不进行限定。
此外，当贴合元件的第一部件的边缘设置有凸耳部时，例如，对于触摸屏而言，其显示模块的边缘上组装有凸耳部，为了避免所述凸耳部与该贴合强度测试治具之间发生干涉，在本公开所提供的实施例中，可选的，如图2至图5所示，在多个所述调节杆100中至少一个调节杆100的杆体110内侧具有台阶结构310，在所述台阶结构310的台阶面312上安装有多个支撑块300，多个支撑块300沿其所在的杆体110的轴向方向(如图4中箭头A1所示)依次排列，且各支撑块300可拆卸地安装在所述杆体110上，以使与所述第一部件上的边缘凸耳部位置正对的支撑块300可拆卸下来以避让所述凸耳部。
采用上述方案，由于一般液晶显示模块上组装有凸耳部，该贴合强度测试治具在进行贴合强度测试时，可以需要根据液晶显示模块上的凸耳部的位置，拆除对应位置上的支撑块300，防止出现干涉而影响测试，其它位置的支撑块300仍用以支撑液晶显示模块的边缘。
其中，所述支撑块300在其所在的杆体110的轴向方向的宽度越小，实验模拟就越精确，可选的，所述支撑块300在其所在的杆体110的轴向方向上的宽度d小于5mm。
此外，可选的，所述支撑块300通过螺栓400可拆卸地安装在所述杆体110内侧的台阶面312上。
采用上述方案，所述支撑块300是通过螺栓拧装在所述杆体110上，拆装方便。应当理解的是，在实际应用中，所述支撑块300还可以采用其他方 式可拆卸地安装在杆体110上，对此并不进行限定。
此外，可选的，如图4和图6所示，所述螺栓400的一端穿过所述支撑块300而旋装于所述台阶面上，所述螺栓400的另一端不超出所述支撑块300的远离所述台阶面一侧的外表面314。
采用上述方案，所述螺栓400位于支撑块300的上方，但是，由于所述调节杆100围设成的容置空间内用以容置显示模块，而触控面板一般尺寸稍大于所述显示模块，其会被所述调节杆100的上方支撑，因此，在上述方案中，所述螺栓400不可突出于调节杆100的用于支撑触控面板的支撑平面。
此外，在所述支撑块300与所述螺栓的选用材料上，综合考虑该贴合强度测试治具的主体结构稳定性、以及所述螺栓和所述支撑块300有可能接触作业人员的手等因素，出于耐磨、防止汗液腐蚀的目的，可选的，所述支撑块300为采用不锈钢材质制成的不锈钢方块；所述螺栓为采用不锈钢材质制成的不锈钢螺栓。
另外，如图1和图4所示，在同一所述调节杆100中，滑块120位于所述杆体110的一端，并与支撑块300和台阶结构间隔设置。换言之，滑块120不与支撑块300接触，且不与台阶结构接触。
以上所述是本公开的可选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
