Description

一种柔性电路板测试设备
本申请要求2021年09月23日提交中国专利局、申请号为202111113658.X、发明名称为“一种柔性电路板测试设备”的发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电路板测试设备技术领域，尤其涉及用于对柔性电路板的各项性能进行测试的设备。
背景技术
在电子设备中，一般会通过柔性电路板来实现各器件之间的电连接。为了避免柔性电路板在使用过程中出现断裂等失效问题，在柔性电路板的设计过程中，通常需要对其性能进行测试，以便对柔性电路板的设计起到指导作用。
由于整机组装之后，其内部的柔性电路板无法直接探测和观察，因此需要借助柔性电路板测试设备来进行测试。
一种典型的柔性电路板测试设备，其主要用于对折叠手机中会随着屏幕的弯折而进行弯折的柔性电路板进行测试。这种测试设备采用双翻板式结构，具有相互铰接的左翻板和右翻板，通过驱动左翻板和右翻板执行开合动作，可模拟手机的开合，从而实现对柔性电路板进行弯折测试，在进行测试时，需要将柔性电路板样品粘贴在左翻板和右翻板的对合面上，柔性电路板样品的两端通过手工焊导线与端子相连，通过数据采集与监视控制系统记录弯折次数及电阻值，以进行进一步分析和判断。
这种测试设备只能简单的模拟柔性电路板的弯折动作，功能较为有限，无法为柔性电路板的设计提供更为全面、准确的测试数据。
例如，每一台上述测试设备只能模拟一种弯折半径，若要模拟不同的弯折半径，只能更换不同的测试设备；而且，这种测试设备也无法模拟柔性电路板的组装形态，尤其对于各部件之间存在折叠、伸缩等相对运动场景的电子设备来讲，由于柔性电路板会在结构件之间活动，因此，对运动轨迹的分析便显得十分重要，而这种测试设备难以对柔性电路板的运动轨迹进行分析。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面结合附图和具体实施方式对本申请作进一步的详细说明。
在本文中，“上、下、内、外”等用语是基于附图所示的位置关系而确立的，根据附图的不同，相应的位置关系也有可能随之发生变化，因此，并不能将其理解为对保护范围的绝对限定；而且，诸如“第一”和“第二”等之类的关系术语仅仅用来将一个与另一个具有相同名称的部件区分开来，而不一定要求或者暗示这些部件之间存在任何这种实际的关系或者顺序。
如图1、图2所示，本实施例提供一种柔性电路板测试设备，该测试设备主要由主夹具1、第一转轴臂2、第二转轴臂3以及副夹具4等部件组成，其通过主夹具1、第一转轴臂2、第二转轴臂3和副夹具4之间的配合来模拟整机中柔性电路板的活动空间，其所形成的半开放式结构，使得柔性电路板5的动态轨迹可视化，配套使用图像采集设备10(例如CCD相机)，可以实现对柔性电路板5运动轨迹和形态的测量记录，完成柔性电路板5弯折过程中的形态测试，解决整机中柔性电路板5的形态无法直接探测的问题。
具体地，如图3、图4所示，主夹具1(图中用一根中心轴表示其安装位置)大体位于设备的中心位置，用于定位柔性电路板5的中部区域，其可以有多种形态和定位方式，例 如可以采用夹持的方式从柔性电路板5的中部对其进行固定。
第一主轴6和第二主轴7分别位于主夹具1的左右两侧，第一转轴臂2通过第一主轴6安装于第一移动台8，第二转轴臂3通过第二主轴7安装于第二移动台9，第一转轴臂2和第二转轴臂3可分别在其移动台上转动，第一移动台8设有第一框架11，第二移动台9设有第二框架12，第一框架11和第二框架12均为竖向地固定在第一移动台8和第二移动台9上的矩形框架，其两则的竖向侧板呈上窄下宽的梯形，以提高框架的结构强度和稳定性，第一主轴6和第二主轴7分别安装在第一框架11与第二框架12相邻近的一边，也就是接近主夹具1的一边。
第一转轴臂2和第二转轴臂3可以直接与第一主轴6和第二主轴7相连接，也可以通过连接件与第一主轴6和第二主轴7间接地连接。
请一并参考图5、图6、图7，第一移动台8和第二移动台9分别设有第一驱动部件13和第二驱动部件14，在本实施例中，第一驱动部件13和第二驱动部件14均为电机，第一驱动部件13竖向地安装在第一移动台8上，其动力输出轴从第一移动台8的下方向下延伸，第一驱动部件13的动力输出轴上设有第一传动轮15，第一主轴6的下端穿过第一移动台8向下延伸，其下端安装有第二传动轮16，第一传动轮15与第二传动轮16通过传动带17传动连接，当第一驱动部件13运行时，便可以驱动第一主轴6旋转，进而带动第一转轴臂2转动。
同理，第二驱动部件14竖向地安装在第二移动台9上，其动力输出轴从第二移动台9的下方向下延伸，第二驱动部件14的动力输出轴上设有第三传动轮18，第二主轴7的下端穿过第二移动台9向下延伸，其下端安装有第四传动轮19，第三传动轮18与第四传动轮19通过传动带(图中未示出)传动连接，当第二驱动部件14运行时，便可以驱动第二主轴7旋转，进而带动第二转轴臂3转动。
通过第一驱动部件13和第二驱动部件14可以驱动第一转轴臂2和第二转轴臂3执行展开、闭合动作，从而模拟产品(例如折叠机)的实际使用状态。
第一移动台8与第二移动台9可以不在同一水平面上，本实施例中，第一移动台8低于第二移动台9，两者在高度上相互错开，这样可以避免两者在执行开合动作、以及后续调节过程中在结构上相冲突。
第一移动台8和第二移动台9分别设有移动台驱动机构，所设置的移动台驱动机构用于带动第一移动台8和第二移动台9在水平面内移动，从而调节两者相对于主夹具1的位置。
具体地，以第一移动台8的移动台驱动机构为例，该移动台驱动机构具有基座20和中间载体21，中间载体21平行于基座20设置，第一移动台8通过第一滑轨22安装在中间载体21上，中间载体21设有第三驱动部件23，通过第三驱动部件23可以驱动第一移动台8沿第一滑轨22在X方向上移动，中间载体21通过第二滑轨24安装在基座20上，基座20设有第四驱动部件25，通过第四驱动部件25可以驱动中间载体21连同其所承载的第一移动台8沿第二滑轨24在Y方向上移动。
第二移动台9的移动台驱动机构与第一移动台8的移动台驱动机构在结构上相同，两者可左右对称布置。
鉴于在本实施例中，第一移动台8低于第二移动台9，因此，视觉可见地，第一移动台8的移动台驱动机构也低于第二移动台9的移动台驱动机构，在结构上体现为第二移动台9的基座20要高于第一移动台8的基座20一定距离。
在本实施例中，第三驱动部件23和第四驱动部件25均为直线电机，第一移动台8和第二移动台9一共设有两台第三驱动部件23和两台第四驱动部件25。当然，也可以采用其他类型的电机来进行驱动，若采用输出旋转运动的电机，则需要增设相应的动力转换机构，以便将电机的旋转运动转变为直线运动，例如齿轮、齿条机构，等等。
由于第一转轴臂2和第二转轴臂3分别安装在第一移动台8和第二移动台9上，因此，通过移动驱动机构可以使移动台、转轴臂和主轴整体移动，使第一转轴臂2的第一主轴6和第二转轴臂3的第二主轴7在X、Y方向上均可调整，从而能模拟0.3mm-2.0mm的弯折半径，实现弯折半径的无级调节，能够进行不同半径的弯折测试，兼容大部分折叠机场景，仅使用一套设备能满足不同产品开发需求。
本实施例还设有图像采集设备10，图5、图7中所示的图像采集设备10均为CCD相机，该图像采集设备10用于观测和记录柔性电路板5的运动轨迹和形态，能实时抓取转轴臂不同角度下柔性电路板5的动态弯折形态，并计算时刻下的弯折半径，能实现放大，位置移动的功能，用于检测关键位置的FPC形态。
而且，该图像采集设备10通过位置调节机构101架设于主夹具1上方区域，通过控制位置调节机构101，可以调整图像采集设备10的观测和拍摄位置，以满足不同的测试需求。
如图9、图10所示，第一转轴臂2和第二转轴臂3的内部形成有夹层空间，从而可以模拟柔性电路板5的活动空间。
第一转轴臂2和第二转轴臂3均设有副夹具4，柔性电路板5的中部被主夹具1定位之后，其两端分别进入第一转轴臂2和第二转轴臂3的夹层空间，在夹层空间中，柔性电路板5的两端被副夹具4定位，同时，柔性电路板5的两端与副夹具4在电路上导通，从而实现电路连接。
通过在第一转轴臂2和第二转轴臂3上形成的夹层空间来模拟柔性电路板5的活动空间，可以对柔性电路板5的实际组装形态和运动轨迹进行测试，从而为柔性电路板5的设计提供更为全面、准确的测试数据。
具体来讲，第一转轴臂2和第二转轴臂3均具有基板26和位于基板对合面一侧的夹板27，夹板27与基板26相连接，第一转轴臂2的基板26与第一主轴6相连接，第二转轴臂3的基板26与第二主轴7相连接，夹板27与基板26连接之后，两者之间形成用于模拟柔性电路板5活动空间的夹层空间。
在本实施例中，副夹具4的数量为多个，多个副夹具4在基板26上沿竖向方向布置，在进行测试时，多个待测试的柔性电路板5以横向的姿态，平行地安装在夹层空间内，可以同时对多组柔性电路板5进行测试，为了便于进行操作和观察，夹板27上开设有对应于副夹具4的竖向框口，以露出一部分副夹具4。这样，整个夹层空间便被构造为半开放式结构，在与整机环境高度一致的情况下，便于进行操作、观测和拍摄，使测试数据的采集变的更加简单易行，且测试数据也更加准确。
夹板27与基板26之间设有第一调节机构，通过第一调节机构可以调节夹板27与基板 26之间的间距，从而模拟不同厚度的夹层空间。
第一调节机构的结构为：基板26在远离主夹具1一侧的上边缘和下边缘分别设有上连接板261和下连接板262，上连接板261和下连接板262均垂直于基板26的板面，夹板27在远离主夹具1一侧的上边缘和下边缘设有上连接板271和下连接板272，上连接板271和下连接板272均垂直于夹板27的板面，基板26的上连接板261与夹板27的上连接板271通过上连接件相连接，基板26的下连接板262与夹板27的下连接板272通过下连接件相连接，上连接件和下连接件均可以采用螺栓(图中未示出)，上连接板261、271和下连接板262、272上的螺栓孔为长度方向垂直于基板26板面的长圆孔。这样，在旋松螺栓之后，便可以沿长圆孔方向调节夹板27与基板26之间的间距，重新锁紧螺栓，便可以将夹板27固定在调整之后的位置，其调整幅度可以在0mm-10mm之间。
第一转轴臂2的横向宽度小于第二转轴臂3的横向宽度，第一转轴臂2的上下两端均超出第二转轴臂3的上下两端。这样，在对合状态下，第一转轴臂2的上连接板261、271和下连接板262、272与第二转轴臂3的上连接板261、271和下连接板262、272便可以相互错位(见图20)，从而避免在结构上相冲突。
如图11、图19所示，夹板27与其上连接板271和下连接板272之间设有第二调节机构，第二调节机构用于调节夹板27与基板26之间的夹角，下面以第一转轴臂2的夹板27为例，对第二调节机构的结构进行介绍。
夹板27与其上连接板271和下连接板272通过摆动轴28相连接，形成可以转动的结构，其中，夹板27的下连接板272在底部设有第五驱动部件29，本实施例中的第五驱动部件29为电机，第五驱动部件29用于带动夹板27绕摆动轴28转动，同理，第二转轴臂3的夹板27也采用同样的结构进行调节；基板26的下连接板262设有对应于第五驱动部件29的让位结构30，此让位结构30呈框口形状，在通过第二调节机构对夹板27与基板26之间的角度进行调节时，第五驱动部件29可以在框口内移动，从而避免在调节时，基板26的下连接板262与第五驱动部件29在结构上相冲突。
第一转轴臂2的转动运动不仅与第二转轴臂3相互独立，而且，通过设置第二调节机构，第一转轴臂2和第二转轴臂3在整体转动的基础上，其夹板27还可以实现独立的转动自由度，从而模拟整机折叠后中框与屏幕间的夹角，进一步增强了测试功能。
如图8、图12所示，基板26设有用于容纳副夹具4的槽位，多个副夹具4连为一体形成副夹具组件，副夹具组件通过第三调节机构安装于基板26的槽位中，第三调节机构用于调节副夹具组件相对于基板26的姿态。
具体来讲，第三调节机构主要由位于副夹具组件上下两端的上转轴31和下转轴32组成，副夹具组件通过上转轴31和下转轴32可转动地安装于基板26的槽位中，其中，下转轴32的下端连接有调节盘33，此调节盘33上开设有以下转轴为中心的多个连接孔34，处于对角线上的每两个连接孔为一组，可通过螺钉或螺栓与基板26的下端面相连接，当通过不同的连接孔与基板26连接时，便可以将副夹具组件固定在不同的角度，图中所示的副夹具4与基板26之间的角度，可以在-45°、0°、+45°三挡之间调节，从而模拟不同的整机架构空间，例如不同转轴空间的折叠屏手机中，柔性电路板5开合运动过程的形态。
也就是说，在0°夹角下，柔性电路板5被主夹具1和副夹具4固定之后，大体呈平 整的状态，其两端大体垂直于副夹具4，而在-45°、+45°夹角下，柔性电路板5不再处于完全平整的状态，其两端与副夹具4之间会存在一个非90°的夹角，从而模拟实际当中柔性电路板5与其他电器部件之间可能存在的不同连接方式和/或引出方式。
如图13所示，在其他实施例中，副夹具组件与基板26之间还可以设有第四调节机构，此第四调节机构用于调节副夹具组件在基板26上的横向位置。
例如，第四调节机构可以具有设于基板26上边缘和下边缘的滑槽35，上述第三调节机构的上转轴31和下转轴32能够在滑槽35内沿横向方向移动并通过定位部件36进行定位，同时，基26板的板面上设有为副夹具组件提供横向移动空间的空心区域。
这样，通过横向调节上转轴31和下转轴32在基板26上的位置，便可以调节左右副夹具4之间的距离，从而可以对各种不同长度的柔性电路板5进行测试，进一步拓宽了测试设备的测试范围。
如图14、图15所示，副夹具4除了能够对柔性电路板5的两端进行定位之外，还设有电连接结构，其电连接结构主要由能够相互扣合的电连接座37和电连接盖38构成，电连接座37与电连接盖38之间形成有用于容纳柔性电路板5端部的空间，电连接盖38的内表面设有导电针39，导电针39采用微针结构，与柔性电路板5端部的焊盘51一一对应，电连接座37的内表面设有用于对柔性电路板5的端部进行定位的定位柱40。
柔性电路板5的端部开设有定位孔，在进行测试时，首先将柔性电路板5上的定位孔对准电连接座37上的定位柱40，放入电连接座37中，然后将电连接38盖扣合在电连接座37上，将柔性电路板5夹持固定，同时，电连接盖38内表面的若干导电针39与柔性电路板5端部的焊盘51接触，实现电路导通。
柔性电路板5两端通过副夹具4的导电针39完成通电，无需手工焊接导线，节约设备空间，柔性电路板5设计兼容性好，在柔性电路板动5态弯折测试过程中，全程上电并记录阻值变化，若柔性电路板5电阻值增或断路，可以设定自动暂停测试，并记录此时柔性电路板5的形态、弯折次数、弯折角度，完成柔性电路板5的寿命测试。
请参考图9、图17、图18，本申请提供的柔性电路板测试设备，通过在第一转轴臂2和第二转轴臂3上形成的夹层空间来模拟柔性电路板5的活动空间，可以对柔性电路板5的实际组装形态和运动轨迹进行测试，从而为柔性电路板5的设计提供更为全面、准确的测试数据，而且，位于主夹具1两侧的移动台能够在驱动部件的驱动下移动，可以调节第一转轴臂2和第二转轴臂3相对于主夹具1的位置，从而可以调整柔性电路板5的弯折半径，进行不同半径的弯折测试，兼容大部分产品(例如折叠机)的实际使用场景。
采用本申请提供的柔性电路板测试设备，至少可以进行以下不同类型的项目测试：
测试项目一：
通过调整第一主轴6和第二主轴7的间距，在不同弯折半径下，进行数量级为万次的弯折测试后，是否存在失效或者微损伤。例如，不同弯折半径可以是0.30mm、0.45mm、0.60mm、1.0mm等。
这一测试项目，可以通过调整设备参数，摸底不同弯折半径、柔性电路板长度等参数条件下，柔性电路板5的最佳设计方案，寻找产品设计最优解。
测试项目二：
单次测试10个柔性电路板5，进行数量级为万次的弯折测试，检测柔性电路板5通路电阻值并记录，电阻值增大10％判定为失效，记录此时柔性电路板5的弯折次数、弯折角度。
这一测试为柔性电路板动态弯折可靠性摸底测试，用于分析当前设计方案下柔性电路板5的弯折性能基线，通过失效柔性电路板5单体失效分析，可找出失效位置，从而进行设计优化。
测试项目三：
单次测试1个柔性电路板5，进行数量级为万次(例如5万次)弯折测试，检测5000/1万/2万/5万次弯折测试后，柔性电路板5在0°/30°/45°/90°情况下的弯折形态，测量弯折半径。
这一测试项目可以测试柔性电路板5弯折半径是否符合要求，是否存在潜在风险，还可以测试多次弯折后，柔性电路板5的形态一致性。
测试项目四：
模拟180°静态弯折场景下柔性电路板5的形态：第一转轴臂2和第二转轴臂3闭合后，使柔性电路板5达到最大弯折状态，主夹具1释放柔性电路板5，副夹具4分别固定柔性电路板5两端，模拟180°弯折场景下柔性电路板5的形态，主夹具位置用于模拟弯折区域空间，副夹具用于控制柔性电路板5的落差及长度。
上述实施例仅是本申请的优选方案，具体并不局限于此，在此基础上可根据实际需要作出具有针对性的调整，从而得到不同的实施方式。例如，基板26和夹板27通过其他方式相互连接，或者，将副夹具4电连接结构中的导电针39改设在电连接座37上(见图16)，等等。由于可能实现的方式较多，这里就不再一一举例说明。
使用该测试设备，可以将柔性电路板5的弯折寿命测试前移，不依赖于项目整机结构件、转轴等物料齐套后再开展测试，可靠性问题激发超前于产品开发，提前识别风险，减少项目转轴柔性电路板5相关设计变更，降低项开发成本，集中测试项目，专注于柔性电路板5相关性能测试，消除其他产品问题导致测试提前终止的问题，有效规避风险。
以上对本申请所提供的柔性电路板测试设备进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也落入本申请权利要求的保护范围内。
