本申请要求于2019年05月27日提交中国专利局的申请号为2019104479997、名称为“样本旋转架及拉曼光谱检测仪”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及生物科学研究与应用技术领域，具体而言，涉及一种样本旋转架及拉曼光谱检测仪。
背景技术
拉曼散射也称拉曼效应，指的是入射光与介质的分子运动间相互作用而引起的频率发生改变的散射，其频率的改变是由于分子极化率的改变(电子云发生变化)而产生的。
散射光与入射光之间的频率差称为拉曼位移，拉曼位移与入射光频率无关，它只与散射分子本身的结构有关。拉曼位移的大小取决于分子振动能级的变化量，不同化学键或基团固有特征的分子振动能级的变化量不同，因此与之对应的拉曼位移也是不相同的。因此，拉曼光谱可以作为分子结构定性分析的依据。拉曼光谱仪主要应用于对物质成分的判定与确认，也可以应用于刑侦及珠宝行业，比如对毒品进行检测以及对宝石进行鉴定。
但现有的拉曼光谱仪操作复杂、检测效率低下。
发明内容
本申请的目的包括提供一种样本旋转架及拉曼光谱检测仪，以改善现有技术中的拉曼光谱仪存在的操作复杂、检测效率低下等问题。
本申请通过以下技术方案实现：
第一方面，本申请提供的一种样本旋转架，包括旋转本体以及设于其上的多个样本载体；多个所述样本载体绕所述旋转本体的周向分布，并能够由位于所述旋转本体外围的光线照射。
在上述技术方案的基础上，进一步，所述样本载体为环套，多个所述环套绕所述旋转本体周向设置，用于插入试管并固定试管。
该技术方案的技术效果在于：试管可直接装载溶液样本，且由于试管管壁透明，方便 激光器直接照射样本。而为了固定放置试管，可选择在旋转本体的周向设置环套、卡口或者夹持组件。其中，卡口或者夹持组件都能固定试管，不过由于试管在实验过程中发生周向转动，故优选将样本载体设计为环套结构，利于固定试管。进一步地，由于此时在环套上放置试管，可在旋转本体对应于任意一个试管底端的位置设置一个带磁性的部件，或者在旋转本体的周向设置一个带磁性的圆环，利于吸引试管中带有磁性的溶质。
进一步地，所述旋转本体呈筒状，所述样本载体为设于所述旋转本体侧壁的管腔，多个所述样本载体绕所述旋转本体周向设置；所述管腔的长度方向与所述旋转本体的轴线方向平行；任一所述管腔远离所述旋转本体轴心的侧壁上设置观察窗；多个所述管腔底部连通。
该技术方案的技术效果在于：管腔用于承载免疫层析试纸条，而入射光线和散射光线分别照射至观察窗并返回。当多个管腔通过底部实现连通时，则多个管腔的试纸条用于检测同一个样本的多个生物学指标。旋转本体转动时，可检测同一样本的不同指标特征。由于多个管腔底部连通，在旋转本体的中轴位置上端设置一个统一的溶液样本注入口。
进一步地，所述管腔从所述旋转本体的一端的端面向所述旋转本体的另一端延伸。
进一步地，在旋转本体设置有一个与各所述管腔连通的注入通道，所述注入通道在旋转本体的端面上具有注入口。

可选地，所述旋转本体呈筒状，所述样本载体为设于所述旋转本体侧壁的管腔，多个所述样本载体绕所述旋转本体周向设置；所述管腔的长度方向与所述旋转本体的轴线方向平行；任一所述管腔远离所述旋转本体轴心的侧壁上设置观察窗；全部所述管腔相互不连通。
该技术方案的技术效果在于：管腔用于承载免疫层析试纸条，而入射光线和散射光线分别照射至观察窗并返回。当各个管腔分别独立没有连通时，则任一管腔中的试纸条分别用于检测一个独立的样本。旋转本体转动时，可同时检测多个样本的特征。
在上述技术方案的基础上，进一步，任一所述管腔的侧壁均设置有连通所述管腔的灌注口。
该技术方案的技术效果在于：由于分别检测不同的溶液样本，需要多次灌注，故在各个管腔的侧壁单独设置灌注口，从管腔的外沿置入待检测溶液样本。
进一步地，所述管腔的外侧壁上设置有灌注结构，所述灌注结构凸出地设置于所述管腔的外侧壁，所述灌注结构中具有与管腔3连通的通道，所述灌注口设置于所述灌注结构并与所述灌注结构的通道连通。
进一步地，所述灌注口朝所述旋转本体的轴向设置。
在上述任一技术方案的基础上，进一步，多个所述样本载体绕所述旋转本体的周向均匀分布。
该技术方案的技术效果在于：由于样本载体均匀分布，在驱动旋转本体旋转时，定位更准确。每转动特定的角度时，即可对下一个管腔的试纸进行照射。
第二方面，本申请还提供一种拉曼光谱检测仪，包括激光器、光谱分析仪、拉曼探头、旋转台以及上述的样本旋转架；所述样本旋转架设置于所述旋转台上，所述拉曼探头设置在所述样本旋转架的外围，所述拉曼探头分别与所述激光器、所述光谱分析仪电连接；所述激光器用于通过所述拉曼探头向所述样本旋转架发射激发光，所述拉曼探头能够接收所述样本旋转架的拉曼散射光并将拉曼散射光返回至所述光谱分析仪。
在上述技术方案的基础上，进一步，样本旋转架下可设置二维手动平移台，实现将样本旋转架整体可拆卸地安装在旋转台上。二维手动平移台同时具有平移和升降功能。通过手动上下调节二维平移台可实现样本旋转架的上下移动，从而实现拉曼探头发出的入射光线在样本旋转架的检测线(T线)和控制线(C线)的切换。同理，通过手动前后调节二维平移台的旋钮，可实现样本旋转架的前后移动。
在上述技术方案的基础上，进一步，还包括复位装置；所述复位装置设置于所述旋转台。
该技术方案的技术效果在于：复位装置可设定每个检测过程都从特定的一个管腔开始。此时，当并未使用全部管腔时尤其有用，节省了时间，提高了检测效率。
在上述任一技术方案的基础上，进一步，还包括升降机构，所述样本旋转架通过所述升降机构设置在所述旋转台上。
该技术方案的技术效果在于：通过上下调节升降机构，实现拉曼探头发出的入射光线在样本旋转架的检测线(T线)和控制线(C线)的切换。
进一步地，所述升降机构包括汽缸或直线电机。
在上述任一技术方案的基础上，进一步，还包括平移机构，所述样本旋转架通过所述平移机构设置在所述旋转台上，所述平移机构能够改变所述样本旋转架与所述拉曼探头之间的距离。
该技术方案的技术效果在于：通过调节平移机构改变样本旋转架与拉曼探头之间的距离，可调整拉曼探头发出的入射光线在样本旋转架上的激光焦距。
进一步地，所述平移机构包括汽缸或直线电机。
可选地，可以将升降机构和平移机构组合设置为一套装置，对样本旋转架的空间位置进行统一控制。
可选地，还可以设置与光谱分析仪电连接显示屏，将光谱分析仪的分析结果通过图表输出，便于实验人员直接读取样本溶液的全部反应数据。
可选地，还可以设置与激光器、光谱分析仪电连接充电电池。充电电池能够防止出现电源突然中断从而造成实验失效的情况，也为了方便在不容易连接电源的环境使用设备，充电电池起到很重要的作用。
本申请提供的样本旋转架以及拉曼光谱检测仪至少具有以下有益效果：
本申请提供的样本旋转架，包括了旋转本体以及设于其上的多个样本载体，多个样本载体绕旋转本体的周向分布。因此可以在尽量小的空间内布置尽量多的样本载体，并通过转动旋转本体可快速地对多个样本实施光学照射，从而在多样本的检测中，可以简化操作，提高检测效率。
本申请提供的拉曼光谱检测仪，包括激光器、光谱分析仪、旋转台以及上述样本旋转架，因此可快速地对多个样本实施光学分析检测，操作简便，检测效率高。
本申请的附加技术特征及其优点将在下面的描述内容中阐述地更加明显，或通过本申请的具体实践可以了解到。

具体实施方式
下面将结合附图对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请的描述中，需要说明的是，术语“上”、“下”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
在当前技术中，物质成分的判定可以通过拉曼光谱检测仪来实现，拉曼光谱检测仪通过检测拉曼位移来对物质成分进行确认。现有的拉曼光谱检测仪体积庞大、结构复杂、价格高昂、操作步骤繁多，并且，单个样本的多指标多次检测和多个样本的统一检测无法实现一次性进行，并且操作复杂繁琐，导致检测效率低下。
为了改善上述的问题，本申请提供一种样本旋转架以及安装有该样本旋转架的拉曼光谱检测仪。为了方便理解本申请提供的样本旋转架及其使用环境，首先对拉曼光谱检测仪进行整体介绍。
图1为本申请实施例提供的拉曼光谱检测仪的第一视角结构示意图；图2为本申请实施例提供的拉曼光谱检测仪的第二视角结构示意图。如图1和图2所示，本申请提供的拉曼光谱检测仪，包括激光器6、光谱分析仪7、拉曼探头10、旋转台8以及本申请提供的样本旋转架。样本旋转架设置于旋转台8上，旋转台8可以由步进电机11驱动而带动样本旋转架旋转。拉曼探头10设置在样本旋转架的外围并与样本旋转架在径向上相间隔。拉曼探头10分别与激光器6、光谱分析仪7电连接。激光器6通过拉曼探头10能够向样本旋转架发射激发光，导致样本旋转架的试纸产生拉曼散射光，该拉曼散射光由拉曼探头10采集并发送至光谱分析仪7。使用该拉曼光谱检测仪时，多个样本可以同时搭载于样本旋转架上，并通过旋转台驱动可以令样本旋转架上的样本依次收到激发光的照射从而产生散射。如此一来，可以高效地进行多样本的检测，避免了每检测一个样本都要人工装卸、挪移样 本。因此提高了多样本的检测效率。
下面对本申请实施例中的样本旋转架进行具体介绍。
图3为本申请一种实施例提供的样本旋转架的立体图；图4为本申请一种实施例提供的样本旋转架的主视图；图5为本申请一种实施例提供的样本旋转架的俯视图。请参照图3至图5，本申请提供的一种样本旋转架，包括旋转本体1以及设于其上的多个样本载体；多个样本载体绕旋转本体1的周向分布，并能够由位于旋转本体1外围的光线照射。在应用于本申请的拉曼光谱检测仪时，样本载体可以接受到激光器6通过拉曼探头10向样本旋转架发射的激发光。
如图3～5所示，其中，旋转本体1呈筒状，其一端用于连接拉曼光谱检测仪的旋转台8，并且旋转本体1在安装于拉曼光谱检测仪时，其轴线应与旋转台8的旋转轴线重合。在该实施例中，样本载体为设于旋转本体1侧壁的管腔3，多个样本载体绕旋转本体1周向设置。请结合参照图1，在该实施例中，管腔3从旋转本体1远离旋转台8的端面(即图3中上端面)向靠近旋转台8的一端(即图3中的下端)延伸，管腔3的长度方向与旋转本体1的轴线方向平行。任一管腔3远离旋转本体1轴心的侧壁上设置观察窗4，在该结构中，管腔3用于承载免疫层析试纸条，观察窗4用于把层析试纸条的检测线(T线)和控制线(C线)裸露出来。激光器6的光通过拉曼探头10依次分别照射到T线或C线上，激发T线或C线上的生物分子产生拉曼信号，产生的拉曼信号通过拉曼探头10返回。可选的，多个管腔3底部连通，当多个管腔3通过底部实现连通时，则多个管腔3的试纸条用于检测同一个样本的多个生物学指标。旋转本体1转动时，可检测同一样本的不同指标特征。在该结构中，由于多个管腔3底部连通，在旋转本体1的中轴位置上端设置一个统一的溶液样本注入口，该注入口与位于旋转本体1中轴位置的注入通道连通，注入通道与各管腔3的底部连通。注入通道和注入口的设计可以实现同时为全部管腔3注入溶液样本。应当理解，在本申请可选的其他实施例中，多个管腔3的底部可以不连通，在这种情况下，各个管腔3可以用于同时容纳不同的样本，因此可以对不同的样本进行依次检测。
由于样本载体在旋转本体1上绕周向设置，通过旋转来选择要检测的样本，这种结构还有利于节省空间占用。
图6为本申请另一种实施例提供的样本旋转架的立体图；图7为本申请另一种实施例提供的样本旋转架的主视图；图8为本申请另一种实施例提供的样本旋转架的俯视图。如图6～8所示，在本申请可选的另一种实施例中，绕旋转本体1周向分布的样本载体为环套2，多个环套2绕旋转本体1轴线均匀间隔设置，环套2用于插入试管并固定试管(图中未示出)。在该结构中，溶液样本通过换套2固定的试管来装载，且由于试管管壁透明，方便激光器6直接照射样本。当然，为了固定放置试管，除了选择在旋转本体1的周向设置环 套2外，还可以通过卡口或者夹持组件来实现对试管的固定。卡口或者夹持组件都能固定试管，但由于试管在实验过程中会发生周向转动，运动过程中具有一定的离心力，故采用环套2结构方式固定试管可以更好地防止试管产生离心偏移。进一步地，由于此时在环套2上放置试管，可在旋转本体1对应于任意一个试管底端的位置设置一个带磁性的部件，或者在旋转本体1的周向设置一个带磁性的圆环，利于吸引试管中带有磁性的溶质。
图9为本申请再一种实施例提供的样本旋转架的立体图；图10为本申请再一种实施例提供的样本旋转架的主视图；图11为本申请再一种实施例提供的样本旋转架的俯视图。如图9～11所示，在本申请再一种可选的实施例中，多个绕旋转本体1的周向分布的样本载体为设于旋转本体1侧壁的管腔3，多个样本载体绕旋转本体1周向均匀间隔设置。与图3～5所示实施例中的管腔3类似，在图9实施例中，管腔3的长度方向与旋转本体1的轴线方向平行，各管腔3远离旋转本体1轴心的侧壁上设置观察窗4。与图3～5所示实施例中的管腔3不同的是，在本实施例中，全部管腔3相互不连通。在该结构中，管腔3用于承载免疫层析试纸条，而入射光线和散射光线分别照射至观察窗4并返回。当各个管腔3分别独立没有连通时，则任一管腔3其中的试纸条分别用于检测一个独立的样本。旋转本体1转动时，可同时检测多个样本的特征。
如图9～11所示，进一步地，为了方便溶液样本的灌注，各管腔3的侧壁均设置有灌注口5。由于分别检测不同的溶液样本，需要多次灌注，故在各个管腔3的侧壁单独设置灌注口5，从管腔3的外侧置入待检测溶液样本。具体的，管腔3的外侧壁上设置有灌注结构，灌注结构凸出地设置于管腔3的侧壁，灌注结构中具有通道与管腔3内连通，灌注口5设置于灌注结构并与灌注结构的通道连通，灌注口朝所述旋转本体1的轴向设置。
在图3～11中任一实施例的基础上，多个样本载体均可绕旋转本体1的周向均匀分布。由于样本载体均匀分布，在旋转台8驱动旋转本体1旋转时，每次转动固定角度，即可将下一个样本转至检测位置，这样有利于更准确地定位。每转动特定的角度时，即可对下一个管腔3的试纸进行照射。
图1和图2所示的拉曼光谱检测仪的样本旋转架是图3～5所展示的样本旋转架，应当理解，在本申请可选的其他实施例中，拉曼光谱检测仪所采用的样本旋转架也可以是图6～11中任一种样本旋转架。
请继续参照图1和图2，进一步地，拉曼光谱检测仪还可以包括复位装置9。复位装置9设置于旋转台8。在该结构中，复位装置9可设定每个检测过程都从特定的一个管腔3开始。此时，当并未使用全部管腔3时尤其有用，节省了时间，提高了检测效率。具体的，复位装置9可以为传感器，用于检测旋转台8是否处于预设的位置，当检测到旋转台8处于预设位置时，可以以此来确定检测的起点。
在上述实施例的基础上，进一步地，拉曼光谱检测仪还设置有升降机构，样本旋转架可以通过升降机构设置在所述旋转台上。通过上下调节升降机构，实现拉曼探头发出的入射光线在样本旋转架的检测线(T线)和控制线(C线)的切换。具体的，升降机构可以包括直线电机、汽缸等。在本申请可选的其他实施例中，升降机构也可以同时带动旋转台进行升降。
在上述实施例的基础上，进一步地，还设置有平移机构，样本旋转架可以通过平移机构设置在旋转台上，平移机构能够改变样本旋转架与拉曼探头之间的距离。通过调节平移机构改变样本旋转架与拉曼探头之间的距离，可调整拉曼探头发出的入射光线在样本旋转架上的激光焦距。同理，平移机构也可以是直线电机或汽缸等，平移机构也可以带动整个旋转台、升降机构进行平移。
可选地，可以将升降机构和平移机构组合设置为一套装置，对样本旋转架的空间位置进行统一控制。如图1所示，样本旋转架下可设置二维手动平移台12以调整旋转台8以及整个样本旋转架在空间中的位置。在本申请中，二维手动平移台同时具有平移和升降功能。通过手动调节旋钮，使二维手动平移台可带动样本旋转架的上下移动，从而实现拉曼探头10发出的入射光线在样本旋转架的检测线(T线)和控制线(C线)的切换。同理，通过手动调节旋钮，也可以使二维手动平移台带动样本旋转架进行前后移动。
进一步地，拉曼光谱检测仪还可以包括显示屏，显示屏与光谱分析仪7电连接。在该结构中，显示屏可将光谱分析仪7的分析结果通过图表输出，便于用户直接读取样本溶液的全部反应数据。具体的，为了方便用户操作，显示屏可以为触摸屏，来接收用户的指令。
如图10所示，进一步地，拉曼光谱检测仪还可以包括充电电池；充电电池与激光器6、光谱分析仪7电连接。在该结构中，为防止出现电源突然中断从而造成实验失效的情况，也为了方便在不容易连接电源的环境使用设备，充电电池起到很重要的作用。
以上所述的样本旋转架、拉曼光谱检测仪的技术方案，能够较好地改善现有技术中的拉曼光谱仪存在的体积庞大、结构复杂、操作步骤繁多、检测效率低下等问题。本申请提供的样本旋转架，能够在较小的空间内紧凑的布置尽量多的样本载体，通过转动旋转本体1即可迅速对多个样本实施光学照射，并且其结构简单，成本较低。本申请提供的拉曼光谱检测仪，利用激光器6、光谱分析仪7、旋转台8以及上述的样本旋转架，其可快速对多个样本实施光学分析检测，自动化程度较高，检测效率较高。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方 案的范围。
此外，本领域的技术人员能够理解，尽管上述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本申请的范围之内并且形成不同的实施例。例如，在上面的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。另外，公开于该背景技术部分的信息仅仅旨在加深对本申请的总体背景技术的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。
工业实用性
本申请提供的样本旋转架以及设置有该样本旋转架的拉曼光谱检测仪结构紧凑简单，能够简化对多样本进行检测的操作过程，提高了多样本的检测效率。
