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。
一方面，本发明提供一种轨道输送装置，如图1至图5所示，包括底座1和依次排列设置在底座1上的检测轨道2、急诊轨道3、返回轨道4和分别驱动样本架9在检测轨道2、急诊轨道3和返回轨道4内移动的第一驱动机构5、第二驱动机构7和第三驱动机构(未示出)，检测轨道2和/或急诊轨道3的外侧设置有用于控制样本架5移动的阻挡机构6。
本发明的轨道输送装置将通过在检测轨道和/或急诊轨道的外侧设置能够控制样本架停留在检测轨道和/或急诊轨道预定位置的阻挡机构，可以使得位于检测轨道和/或急诊轨道检测位置的样本能够有充分的时间完成检测，防止样本架拥堵在检测位置，避免检测检测样本发生混乱。
本发明一实施例中，阻挡机构6优选包括固定在底座1上的第一电机6-2、与第一电机6-2的输出端连接的第一挡板6-1，第一挡板6-1能够伸 进和伸出检测轨道2和/或急诊轨道3。当位于检测轨道2和/或急诊轨道3的检测位的样本架9未处理完成时，阻挡机构6可以阻止后面的样本架9继续前进，具体工作原理如下：初始状态下，第一挡板6-1位于检测轨道2和/或急诊轨道3的外侧，当需要阻挡样本架9前进时，第一电机6-2驱动第一挡板6-1转动，使第一挡板6-1的端部伸进检测轨道2和/或急诊轨道3内部，当样本架9运动至第一挡板6-1位置时，第一挡板6-1即可阻止样本架9继续前进。当位于检测轨道2和/或急诊轨道3的检测位的样本架9处理完成后，第一电机6-2再次驱动第一挡板6-1返回初始位置，此时，样本架9在第一驱动机构5和/或第二驱动机构7的驱动下可继续前进。
在上述结构中，第一挡板6-1可以从检测轨道2和/或急诊轨道3的上方进入检测轨道2和/或急诊轨道3内部，也可以在检测轨道2和/或急诊轨道3外侧与第一挡板6-1相对应的位置设置第一通槽2-1，第一挡板6-1通过第一通槽2-1伸进伸出检测轨道2和/或急诊轨道3。
上述结构中，还可以在底座1和第一挡板6-1上设置相互作用的光电开关6-4和光电开关挡板6-5用于判断第一挡板6-1是否伸进和伸出检测轨道2和/或急诊轨道3。
本发明一实施例中，检测轨道2和/或急诊轨道3的外侧可以通过设置检测位控制机构8驱动样本架9停留在对应的样本检测位，具体的，检测轨道2和/或急诊轨道3的外侧设置有检测位控制机构8，检测位控制机构8包括固定设置在底座1上的第四驱动机构和与第四驱动机构驱动连接的第一推杆8-5，第一推杆8-5能够伸进和伸出检测轨道2和/或急诊轨道3。第四驱动机构可以采用以下两种结构：
实施例1：
本实施例中，第四驱动机构包括固定设置在底座1上的第二电机8-1、与第二电机8-1的输出端连接的第一同步带传动机构8-2、与第一同步带传动机构8-2固定连接的第一固定板8-6，第一固定板8-6与第一推杆8-5滑动连接，第一推杆8-5上设置有第一滚轮8-4，检测轨道2和/或急诊轨道3的外侧设置有第一连接板8-3，第一连接板8-3的一个端面为能够与 第一滚轮8-4相配合的斜面，第一滚轮8-4沿第一连接板8-3的斜面移动时，第一推杆8-5能够伸进和伸出检测轨道2和/或急诊轨道3。检测位控制机构8的工作原理如下：初始状态下，第一推杆8-5位于检测轨道2和/或急诊轨道3的外侧，第一滚轮8-4位于第一连接板8-3的斜面最外侧。当样本架9需要从停留在检测轨道2和/或急诊轨道3内使其中某一样本位于检测位时，第一滚轮8-4在第二电机8-1的驱动下开始沿第一连接板8-3的斜面运动，进而带动第一推杆8-5在水平和垂直两个方向同时移动，待第一滚轮8-4完全脱离第一连接板8-3的斜面之后，第一推杆8-5伸进检测轨道2和/或急诊轨道3内侧，并在第二电机8-1的驱动下继续水平移动，到达某一样本检测位后停止并阻止样本架9移动，待该样本被取走进行检测后，第二电机8-1驱动第一推杆8-5继续移动，第一推杆8-5每移动一次，样本架移动的距离为两个样本试管的中心距，以保证每个样本均能够停留在检测位，待样本架9内的样本被完全取走后，第一推杆8-5在第二电机8-1的驱动下返回至初始状态，样本架9经过检测轨道2和/或急诊轨道3进入下一程序。
实施例2：
本实施例与实施例1不同的是，第一推杆8-5的水平和垂直运动分别由两个电机驱动同步带的结构实现，两者互不影响，进而实现第一推杆8-5既能伸进伸出检测轨道2和/或急诊轨道3，又能沿检测轨道2和/或急诊轨道3的长度方向移动。
在上述实施例1和2中，为保证第一推杆8-5每次的移动距离，可以在底座1和第一推杆8-5上分别设置相对应的光电开关挡板8-9和光电开关8-10，由光电开关挡板8-9和光电开关8-10配合实现第一推杆8-5的移动。其中，光电开关挡板8-9可以为设置有多个U型槽的长条板，每个U型槽的距离为样本架9中相邻两个样本之间的中心距离。
上述实施例1和2中，还可以设置分别导轨滑块机构8-7/8-8对第一推杆8-5的水平和垂直移动进行导向。
在上述实施例1和2中，第一推杆8-5可以从检测轨道2和/或急诊轨 道3的上方进入检测轨道2和/或急诊轨道3内部，也可以在检测轨道2和/或急诊轨道3外侧与第一推杆8-5相对应的位置设置第二通槽2-2，第一推杆8-5通过第二通槽2-2伸进伸出检测轨道2和/或急诊轨道3。
本发明一实施例中，检测完毕或者需要重测的样本架9经过返回轨道4返回样本架回收区，返回轨道4内的样本架9可以通过设置在返回轨道4外侧的退回机构11返回，退回机构11包括设置于底座1上的第五驱动机构和与第五驱动机构驱动连接的第二推杆11-6，第二推杆11-6能够伸进和伸出返回轨道4内并能够沿返回轨道4的长度方向移动。第四驱动机构可以采用以下两种结构：
实施例3：
本实施例中，第五驱动机构包括设置于底座1上的第三电机(未示出)、与第三电机的输出端连接的第二同步带传动机构11-1和与第二同步带传动机构11-1固定连接的第二固定板11-2，第二固定板11-2与第二推杆11-6滑动连接，第二推杆11-6上设置有第二滚轮11-3，返回轨道4的外侧设置有第二连接板11-4，第二连接板11-4的一个端面为能够与第二滚轮11-3相配合的斜面，第二滚轮11-3沿第二连接板11-4的斜面移动时，第二推杆11-6能够伸进和伸出返回轨道4。退回机构11的工作原理如下：初始状态下(如图12所示)，第二推杆11-6位于返回轨道4的外侧，第二滚轮11-3位于第二连接板11-4的斜面最外侧。当样本架9到达返回轨道4靠近缓存区1-3的端部时，第二滚轮11-3在第三电机的驱动下开始沿第二连接板11-4的斜面运动，进而带动第二推杆11-6在水平和垂直两个方向同时移动，待第二滚轮11-3完全脱离第二连接板11-4的斜面之后，第二推杆11-6伸进返回轨道4内侧，并在第三电机的驱动下继续水平移动，直至将样本架9完全推入样本架回收区，之后第二推杆11-6在第三电机的驱动下返回至初始状态。
实施4：
本实施例中与实施例3不同的是，第五驱动机构采用两个电机(未示出)分别控制第二推杆11-6伸进伸出返回轨道4以及沿返回轨道的长度 方向移动。
上述实施例3和4中，可以在底座1和第二推杆11-6上分别设置相对应的第一光电开关挡板11-9和第一光电开关11-8，由第一光电开关挡板11-9和第一光电开关11-8配合确定第二推杆11-6的初始状态和最终状态。
上述实施例3和4中，还可以设置分别导轨滑块机构11-5/11-7对第二推杆11-6的水平和垂直移动进行导向。
上述实施例3和4中，第二推杆11-6可以返回轨道4的上方进入返回轨道4内部，也可以在返回轨道4外侧与第二推杆11-6相对应的位置设置第三通槽4-1，第二推杆11-6通过第三通槽4-1伸进伸出返回轨道4。
本发明一实施例中，轨道输送模块的末端还可以设置有变轨机构10以实现样本架9由检测轨道2和急诊轨道3向返回轨道4的转移。
本发明一实施例中，变轨机构10包括设置于底座1上的第四电机10-1、与第四电机10-1驱动连接的第三同步带传动机构10-3和与第三同步带传动机构10-3固定连接的第二挡板10-2。第二挡板10-2既可以位于检测轨道2的外侧，也可以位于检测轨道2的正上方。当第二挡板10-2位于检测轨道2的外侧时，变轨机构10还包括位于第二挡板10-2下方的与检测轨道2、急诊轨道3和返回轨道4对应的变轨轨道，变轨轨道可以采用电机驱动同步带的结构形式实现样本架9由检测轨道2和急诊轨道3向返回轨道4的转移。当第二挡板10-2位于检测轨道2的上方时，可以将第一驱动机构5、第二驱动机构7和第三驱动机构的同步带延长或者将检测轨道2、急诊轨道3和返回轨道4的第二挡板10-2缩短，第二挡板10-2将样本架9转移至返回轨道4后，可以由第三驱动机构直接驱动样本架9在返回轨道4内移动。
另一方面，本发明还提供一种分析仪，包括上述任一所述的轨道输送装置。
本发明的分析仪可以是单个仪器设备如生化分析仪、酶联免疫分析仪、化学发光免疫分析仪等，也可以是多个仪器组合在一起的流水线系统。
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。
