Description

用于处理样品容器的夹持装置和分析仪器
技术领域
本发明涉及一种用于处理样品容器的夹持装置以及一种分析仪器。
发明内容
本发明的目的是提供一种用于处理样品容器的夹持装置以及提供一种高度灵活(flexible)和高性能的分析仪器。
夹持装置适于处理例如呈常规样品管形式的样品容器。样品容器被给定帽类型的帽封闭或者未被帽封闭。该帽类型可选自一组不同的帽类型。不同类型的样品容器可例如被不同类型的帽封闭。
夹持装置包括多个指状件,所述指状件适于共同地夹持样品容器和/或适于引起对样品容器的夹持。
夹持装置还包括触觉传感器装置,该触觉传感器装置布置在所述指状件中的至少一个处和/或机械地联接到所述指状件中的至少一个。触觉传感器装置适于对所夹持的样品容器以及帽(如果有的话)的纵向轮廓进行测量和/或采样。纵向轮廓是在样品容器的纵向延伸部中的轮廓。
夹持装置还包括联接到触觉传感器装置的控制装置,其中,该控制装置适于基于采样得到的纵向轮廓来确定样品容器是被帽封闭还是未被帽封闭。采样得到的纵向轮廓依赖于样品容器是否被帽封闭。通常,帽的未被插入到样品容器中的部分具有另一个直径,特别是比样品容器更大的直径。因此,采样得到的纵向轮廓特别地在样品容器和帽之间的过渡位置处改变。因此,控制装置可例如评估采样得到的纵向轮廓的梯度,以确定是否存在帽。附加地或替代地,控制装置可将采样得到的纵向轮廓与具有/没有帽的已知样品容器的所存储的纵向轮廓进行比较。
根据实施例,触觉传感器装置包括多个(例如,在2和100个之间)触觉传感器,所述触觉传感器能够移动并沿着指状件中的至少一个纵向地布置以对纵向轮廓进行采样。触觉传感器可以是轴向可移动的。触觉传感器可以是能够沿垂直于所夹持的样品容器的纵向轴线的方向移动的。
根据实施例,如果控制装置确定样品容器被帽封闭,则控制装置还适于确定帽类型,特别是基于采样得到的纵向轮廓。通常,采样得到的纵向轮廓对于帽类型而言是特征化的。因此,可以基于采样得到的纵向轮廓来确定帽类型。控制装置可例如将采样得到的纵向轮廓与已知帽类型的所存储的纵向轮廓进行比较。控制装置还可使用感测到的帽颜色来确定帽类型。
根据实施例,帽包括待插入到样品容器中的基部部分,其中,如果控制装置确定样品容器被帽封闭,则控制装置还适于基于采样得到的纵向轮廓来确定基部部分被插入到样品容器中的程度。通常,帽包括待插入到样品容器中的基部部分以及包括相邻的头部部分,该头部部分具有比样品容器更大的直径。如果基部部分被完全插入到样品容器中,则在样品容器和头部部分之间的过渡位置处采样得到的轮廓在由样品容器的直径确定的值和由头部部分确定的值之间变化。如果基部部分未被完全插入到样品容器中,则采样得到的轮廓在如下值之间变化,所述值为:由样品容器的直径确定的值、然后由基部部分的直径确定的值、且然后由头部部分确定的值。因此,可确定基部部分的未被插入到样品容器中的长度。进一步地,如果帽类型是已知的,则帽的几何性质(例如基部部分和头部部分的纵向延伸部)是已知的。因此,可以基于采样得到的纵向轮廓来计算基部部分被插入到样品容器中的程度。
根据实施例,所述多个触觉传感器中的每一个包括:销,其是轴向可移动的;以及位移测量单元,其适于测量轴向可移动销的轴向位移。纵向轮廓由触觉传感器的轴向位移形成。
根据实施例,触觉传感器是弹簧加载的,使得轴向可移动销借助于弹簧力而压靠所夹持的样品容器的表面。
根据实施例,所述多个触觉传感器沿着所述多个指状件中的每一个纵向地布置。如果例如夹持装置包括两个指状件,则多个触觉传感器沿着第一指状件纵向地布置,并且相同数量的触觉传感器沿着第二指状件纵向地布置。
根据实施例,指状件的数量是两个。
根据实施例,夹持装置还包括颜色传感器,该颜色传感器适于感测所夹持的帽(如果有的话)的颜色。控制装置可适于依赖帽的颜色来确定帽类型。
分析仪器包括如上文所描述的夹持装置。该分析仪器通常包括与夹持装置相互作用的另外的部件,例如用于处理包含在样品容器中的样品的装置、离心机、用于分装的装置等。

如所描绘的,夹持装置1包括两个L形指状件4,两个L形指状件适于借助于对应的夹持表面4a来共同地夹持样品容器2。指状件4可被打开以释放样品容器2(见图2),或者可被闭合以夹持样品容器2(见图3)。
可借助于未明确描绘的常规驱动机构(例如,呈电动马达的形式)来转移/移动/旋转指状件4。
夹持装置1还包括触觉传感器装置,该触觉传感器装置包括多个触觉传感器5,所述触觉传感器沿着指状件4纵向地布置(即,沿纵向方向LD)以对所夹持的样品容器2和帽3(如果有的话)的纵向轮廓LP进行采样。
每个触觉传感器5包括能够沿着其纵向轴线LA移动的销7。销7布置成使得每个销的纵向轴线与所夹持的样品容器2的纵向轴线成直角。
每个触觉传感器5还包括位移测量单元8,该位移测量单元适于测量对应的轴向可移动销7的轴向位移。
每个触觉传感器5还包括弹簧9,使得轴向可移动销7被推压抵靠所夹持的样品容器2的外表面。
纵向轮廓LP可例如表示轴向可移动销7的依赖纵向位置z的轴向位移(沿x方向的位移,即沿纵向轴线LA的方向的位移)。
夹持装置1还包括控制装置6,该控制装置联接到每个触觉传感器5的位移测量单元8,使得控制装置6可以读取纵向轮廓LP。基于纵向轮廓LP,控制装置6确定样品容器2是被帽3封闭还是未被帽封闭。进一步地,控制装置6基于采样得到的纵向轮廓LP来确定帽类型。
参考图2和图3,夹持装置1还包括颜色传感器10,该颜色传感器联接到控制装置6并适于感测所夹持的帽3(如果有的话)的颜色。控制装置可基于帽3的颜色来确定帽类型和/或样品容器类型。
参考图2和图3,夹持装置1还包括可选的距离传感器11,该距离传感器联接到控制装置6并适于感测到所夹持的帽3(如果有的话)的距离。控制装置可基于感测到的距离来控制夹持操作。
参考图1,帽3包括头部部分3a和待插入到样品容器2中的基部部分3b。如果控制装置6确定样品容器2被帽3封闭,则控制装置6基于采样得到的纵向轮廓LP来确定基部部分3b被插入到样品容器2中的程度。
图4描绘了根据另外的实施例的用于处理样品容器2的夹持装置1’。
夹持装置1’包括两个I形指状件4,并且借助于弹簧加载的触觉传感器5来夹持样品容器2,其中,图1中所描绘的夹持装置1借助于指状件4的夹持表面4a来夹持样品容器2。
关于其余的特征,参考有关图1至图3中所描绘的实施例的描述。
根据本发明的夹持装置1/1’能够在处理样品容器的同时确定帽的存在、帽类型、帽被插入到样品容器中的程度、样品容器直径以及帽颜色。
夹持装置1/1’包括在指状件4上的触觉/机械传感器,该触觉/机械传感器包括轴向可移动销7,其中,每个轴向可移动销7独立地响应于由夹持装置1/1’处理/夹持的样品容器2的表面。
位移测量单元8绘制每个销7的轴向位置的分布(map),以产生帽3和样品容器2的纵向轮廓LP。
该轮廓信息LP用于对帽3的类型和帽3被插入到样品容器2内的程度进行分类。
如果帽3的插入不稳定,则在运输/处理期间,轴向可移动销7将帽3保持/固定就位。
附加的颜色传感器10也可被集成在夹持装置1内以用于帽颜色的确定。
