本发明涉及全自动核酸检测分析系统技术领域，具体涉及一种用于全自动核酸分析系统的热盖结构。
背景技术
现有的全自动核酸检测分析系统中，由于仪器体积较大且试剂板放置在仪器内部不显眼的位置，导致操作人员在进行试剂检测前，并不能直观的观察到热盖下方是否正确放置了试剂板。当热盖下方未正确放置试剂板时，仪器虽然也可以进行试剂检测分析操作，不过由于没有正确放置试剂板的缘故，所以分析结果是无效的，而且每次试剂分析都需要消耗几小时，一旦误检则费时费力费成本。
发明内容

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
本发明提供一种用于全自动核酸分析系统的热盖结构，如图1-4所示，包括滑板1、热盖机构、检测机构和设置于滑板1上的驱动机构，热盖机构包括与滑板1滑动连接的热盖固定板12、设置于热盖固定板12下端的热盖13和与热盖13弹性连接的热压板16，驱动机构用于驱动热盖机构相对滑板1垂直运动，检测机构包括与热压板16上端固定连接的第一挡片17，热盖固定板12上设置有与第一挡片17相对应的第一光电开关18。通过滑板1上设置的驱动机构驱动热盖机构相对滑板1进行垂直运动，由于热盖13与热压板16弹性连接，所以热压板16上端固定连接的第一挡片17与热盖固定板12上端设置的第一光电开关18可以在垂直方向上相对运动，当热盖13下方正确放置了试剂板时，第一挡片17在垂直运动过程中能够在某一时刻触发第一光电开关18，全自动核酸分析系统开始进行下一步的试剂检测分析工序。这种结构，可以在试剂检测分析工序前检测热盖13下方是否正确放置了试剂板，避免了误检带来的损失，提高了容错率。
本发明一实施例中，热盖13与热压板16之间设置有弹性件和第一导向杆14。具体的，弹性件与第一导向杆14配合，在热盖13下方正确放置 了试剂板时，导向杆可在弹性件的弹力作用下，相对热盖13垂直向上运动。
热盖13和热压板16连接的方式可以采用以下两种结构：
实施例1：
第一导向杆14为阶梯轴，热盖13的上端设置有与阶梯轴相配合的阶梯通孔。第一导向杆14带动热压板16在阶梯孔内相对热盖13上下移动，阶梯孔的设置能够限定热压板16与热盖13之间的移动距离，防止热压板16掉落。
在本实施例中，第一挡片17可以设置在阶梯轴的上端，随阶梯轴移动，能够与第一光电开关18接触，进一步限定热压板16的移动距离。
实施例2：
热盖13下端位于热盖13内设置有挡板(未示出)，热压板16可放置在挡板(未示出)上。通过设置挡板(未示出)，可以防止热压板16受重力影响而掉落。
本发明一实施例中，弹性件为压缩弹簧15，压缩弹簧15套设在第一导向杆14的外缘。若热盖13下方正确设置了试剂板，则热压板16在相对热盖13垂直运动时，热压板16与试剂板接触挤压，在压缩弹簧15的弹力作用下，带动第一导轨相对热盖13垂直向上运动。
本发明一实施例中，驱动机构包括设置于滑板1上的固定架2和设置于固定架2上的电机6，电机6的输出端设置有齿轮7，热盖固定板12上设置有与齿轮7啮合的齿条9，齿条9的底部与热盖固定板12固定连接，齿条9与滑板1滑动连接。电机6带动齿轮7转动，齿轮7带动齿条9垂直运动，进而齿条9带动热盖固定板12垂直运动，即实现驱动机构带动热盖机构相对滑板1垂直运动；根据热盖固定板12与滑板1之间相对垂直运动的距离，齿条9可滑动穿过滑板1。
本发明一实施例中，滑板1上设置有齿条导向槽8，齿条9滑动设置在齿条导向槽8内。齿条9在齿条导向槽8内滑动，导向槽起到一个导向作用。
本发明一实施例中，热盖固定板12与滑板1之间设置有第二导向杆11。第二导向杆11可以起到导向热盖固定板12垂直运动的作用，避免热盖机构在运动时倾斜。
本发明一实施例中，热盖固定板12上设置有直线轴承10，第二导向杆11上端与滑板1固定连接，第二导向杆11套设在直线轴承10内。具体的，滑板1和第二导向杆11可以相对热盖固定板12向下运动，通过设置直线轴承10，可以使第二导向杆11在垂直运动时更加顺畅。
本发明一实施例中，固定架2上还设置有第二光电开关3和第三光电开关4，热盖固定板12上设置有第二挡片5，热盖固定板12在运动至上限位和下限位时，第二挡片5分别触发第二光电开关3和第三光电开关4。第二挡片5触发第二光电开关3时，驱动机构停止驱动热盖机构继续垂直向上运动；第二挡片5触发第三光电开关4时，热盖13已经完全罩住试剂板，此时驱动机构停止驱动热盖机构继续垂直向下运动，并且，此时第一挡片17触发第一光电开关18，全自动核酸分析系统开始进行下一步的试剂检测分析工序。
本发明的用于全自动核酸分析系统的热盖结构运行原理如下：
热盖13下方正确放置试剂板时：
第一阶段：电机6驱动齿轮7转动，带动齿条9在齿条导向槽8内垂直向下运动，由于齿条9底部与热盖固定板12固定连接，因此齿条9将带动热盖机构在第二导杆的导向下整体垂直向下运动；第二阶段：热压板16接触到试剂板，由于热盖13可以将试剂板罩住，因此热盖13和热盖固定板12会继续垂直向下运动，热压板16则静止不动，即第一光电开关18继续垂直向下运动，第一挡片17静止不动，直到热盖13完全罩住试剂板，即热盖13到达下限位，此时第一挡片17触发第一光电开关18，第二挡片5触发第三光电开关4，全自动核酸分析系统开始进行下一步的试剂检测分析工序，同时，热盖13停止继续垂直向下运动。第三阶段：每个试剂板的检测分析工序结束后，驱动机构驱动热盖13和热盖固定板12垂直向上运动，热压板16先保持静止不动，直到热压板16接触到挡板后，热盖 机构开始整体垂直向上运动，热盖机构整体运动至上限位时，热盖固定板12上的第二挡片5触发第二光电开关3，此时驱动机构停止驱动热盖机构继续垂直向上运动。
热盖13下方未正确放置试剂板时：
第一阶段与热盖13下方正确放置试剂板时的第一阶段相同，不在此赘述；第二阶段：驱动机构驱动热盖机构垂直向下运动，直到热盖13到达下限位时，第二挡片5触发第三光电开关4，此时热盖机构不再继续垂直向下运动，但是由于这个阶段热压板16未接触到试剂板，所以热压板16与热盖13和热盖固定板12始终保持相对静止的状态，因此第一挡片17不会触发第一光电开关18，即不会启动全自动核酸分析系统的下一步试剂检测分析工序；第三阶段：驱动机构驱动热盖机构整体开始整体垂直向上运动，热盖机构整体运动至上限位时，热盖固定板12上的第二挡片5触发第二光电开关3，此时驱动机构停止驱动热盖机构继续垂直向上运动。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
