目前，在平板电脑、手机类电子产品的制造过程中，产品品质检测是非常重要的环节。检测项目一般包括：按键的灵敏度检测、屏幕以及内部各个元件工作状态以及性能的检测、内部组装线路是否导通的检测、通过虚拟程序验证各部件完成装配后能否运行的检测等等。
其中，在按键测试单元部分，传统的测试治具设计都较为简单，一般采用气缸驱动按键按压测试头对被测试产品的按键进行测试。在具体测试的时候，首先由气缸驱动按键按压测试头，而后按键按压测试头向按键的方向运动直至按键按压测试头按压到按键。但是，测试人员发现，在上述测试过程中，无法控制按键按压测试头的按压力度。当按压力度过大时，容易造成按键被按压损坏的情况；当按压力度过小时，由于按键按压测试头没有与按键完全接触或者按压不充分，导致测试结果不准确。
为解决上述问题，需安装压力感应器进行监控，使按键按压测试头的按压力度控制在设定范围内。但是，采用上述气缸结构设计无法安装压力感应器，因此需考虑其他方案替代上述气缸结构设计。
另外，在线路测试单元部分，测试连接端口通常采用与待测产品排线配合的公端子或母端子。这种公母配合连接的方式容易对待测产品排线的端子造成磨损，不能满足精细产品的要求。

该按键按压测试头上设置有压力感应器56。
在具体实施的时候，如图5所示，该下压机械手53包括Y轴连接板531、电机532以及动作单元533，其中，该Y轴连接板531连接在该Y轴机械手52上，该电机532设置在该Y轴连接板531上，该动作单元533连接在该电机532与该按键按压测试头之间，通过该动作单元533将该电机532的驱动作用力进行转换而后驱动该按键按压测试头进行上下往复的按压测试动作。
该动作单元533包括丝杆螺母534、螺母固定板535、等高螺丝536、滑块537。
该丝杆螺母534与该电机532的转动丝杆相螺合，当该电机532工作的时候，该转动丝杆转动，借助该丝杆螺母534与该转动丝杆之间的配合关系，该丝杆螺母534能够沿着该转动丝杆进行上下往复运动。
该丝杆螺母534固定设置在该螺母固定板535上。
该等高螺丝536连接在该螺母固定板535与该滑块537之间。
其中，该等高螺丝536下端固定连接在该滑块537上，该等高螺丝536顶端插设在该螺母固定板535的通孔中。
该等高螺丝536上套设有弹簧(图中未视出)，该弹簧位于该螺母固定板535和该滑块537之间，通过该弹簧使该按键按压测试头在进行下压测试动作时能够起到缓冲作用，以避免该按键按压测试头压坏待测产品。
该按键按压测试头设置在该滑块537下方。
该螺母固定板535、该等高螺丝536、该滑块537以及该按键按压测试头与该丝杆螺母534同步进行上下往复运动以完成下压测试动作。
该压力感应器56安装在该滑块537上，且设置在该按键按压测试头顶部。
为了使该滑块537运动平稳，该滑块537滑动连接在动作轨道538上，该动作轨道538设置在轨道安装板539侧面。
该轨道安装板539顶部连接在该Y轴连接板531下端。
在进行下压测试动作的时候，该滑块537沿该动作轨道538上下往复滑动。
在具体实施的时候，该螺母固定板535上还安装有位移感应片(图中未视出)，其作用是确定起点位置(相当于标注原点的作用)，用来确定该电机532要运动的行程。
在具体实施的时候，该滑块537上还设置有移动标尺540，该移动标尺540与该滑块537同步上下运动。
与该移动标尺540相对应在该轨道安装板539上标注有刻度，便于人眼直接观察上下移动的位置。
在具体实施的时候，还可以通过控制器预先设定下移的距离，防止测试头下压损坏待测产品，且提高测试效率。
在具体实施的时候，该按键按压测试头包括第一按压测试头54以及第二按压测试头55，该第一按压测试头54以及该第二按压测试头55都是采用按压的方式测试按键，只是测试头的具体型号不同，该X轴机械手51设置在该机架10 顶部，该Y轴机械手52设置在该X轴机械手51上方，该下压机械手53设置在该Y轴机械手52一端。
本发明在具体工作的时候，检测人员首先需要将被测试产品放置在该内模板20上，按下启动按钮，产品被该内模板20上的真空吸紧，之后该内模板20旋转使该针模组件30的探针与产品的被测试电路相接触并开始测试，完成之后该内模板20旋转产品随该内模板20转动到水平位置，该X轴机械手51、该Y轴机械手52以及该下压机械手53动作，并分别通过该第一按压测试头54以及该第二按压测试头55对产品的按键进行测试。
在具体实施的时候，该按键测试单元整体被罩设在一保护罩61中，该机架10上设置有一控制台62，该控制台62上设置有若干控制按钮63，该机架10上还设置有一实时显示屏64，该实时显示屏64即时显示检测结果，检测状态。
传统的测试治具的线路测试部分的连接端口都是采用与待测产品排线配合的公端子或母端子方式设计的，由于是采用公母端子配合连接的方式进行连接，所以容易发生对待测产品排线的端子造成磨损的情况，为了避免上述情况的发生，发明人改用探针对接的方式，但是，探针对接的方式容易存在接触不良的现象，因此需设计相应的结构使探针与待测产品排线的端子接触稳定，其具体技术内容如下所述。
在具体实施的时候，如图7所示，该针模组件30包括连接排线32，该连接排线32下端与该主板测试组件31连接，该连接排线32顶端与该针模组件30中的探针相连接，所述线路测试单元还包括测试端口33，该针模组件30中的该探针设置在测试端口33中。
在进行测试的时候，待测试产品排线的连接端子(图中未视出)连接到该测试端口33中，使待测试产品的排线与该测试端口33中的该探针接触后开始进行测试工作。
在上述的过程中为了固定待测试产品的排线使该探针与待测产品排线的端子接触稳定发明人设计出如下技术方案。
该针模组件30还包括排线吸附头34，该排线吸附头34上设置有吸嘴341，在进行测试的时候，该吸嘴341吸附待测产品的排线以固定其位置，同时防止待测产品的排线反弹。
该针模组件30还包括排线压块35，该排线压块35能够压紧待测产品的排线，使待测产品排线的连接端子与该探针紧密接触。
该排线压块35由气缸驱动，该气缸可以设置在该排线压块35的左侧或右侧，优选设置在右侧，如图8所示，设在右侧时，该气缸施加的压力会更大，并能够避免气压不足时，气缸压力不够时，导致该探针和待测排线接触不良情况的发生。
为了进一步固定待测产品排线的空间位置，在该排线吸附头34两侧分别枢接有压紧门36，该压紧门36能够将待测产品的排线压紧在该排线吸附头34上。
左右两个该压紧门36是备用的，不是必要的，是为了防止该吸嘴341失效时使用，在具体实施的时候，该压紧门36通过磁铁吸力进行压紧。
该旋转电机设置在该内模板20一端，该旋转电机通过联轴器连接在该内模板20一端，该内模板20的另外一端通过轴承连接在该机架10中，当该内模板 20需要转动的时候，该旋转电机动作，并借助该联轴器以及该轴承使该内模板20能够围绕其自身轴线方向转动。
该内模板20的上述旋转动作方式是为了配合测试人员将待测产品的排线连接到该针模组件30中进行测试而设计的，当待测产品被放置在该内模板20上之后，该内模板20转动使待测产品的排线部分暴露在外，方便测试人员将待测产品的排线连接到该针模组件30中，在完成排线连接之后，该内模板20反向转动使待测产品的屏幕暴露在外方便测试人员观测、测试。
