    • A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g., −80° C.) storage and retrieval systems which stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are loaded into trays located within an ultra-low temperature freezer compartment (−80° C.). A tube picking mechanism resides in a tube picking chamber that is located adjacent the freezer compartment. The tube picking chamber is maintained at about −20° C. when the tube picking mechanism is in operation. The tube picking mechanism includes a cache within the tube picking chamber to facilitate fast paced shuttling of the tube racks from the freezer compartment into the tube picking chamber. The shuttle has a clamping mechanism to secure a tube rack in place when a gripper head picks a tube from the rack. The system also includes a push pin that pushes on the bottom of the respective tube as it is being picked from the tube rack. A one-dimensional bar code reader is included within the tube picking chamber. The gripper head is able to move vertically and rotate within the field of view of the one-dimensional bar code reader in order to facilitate identification and reading of one-dimensional bar codes located on the sidewall of picked storage tubes. The system also uses fans to facilitate efficient cooling of the tube picking chamber.
    • 管拾取机构被设计用于存储生物或化学样品的自动化,超低温(例如-80℃)的储存和检索系统。 样品包含在保存在SBS足迹存储架中的储存管中,其装载到位于超低温冷冻室(-80℃)内的托盘中。 管拾取机构位于邻近冷冻室的管采摘室中。 当管采摘机构运行时,管采摘室保持在-20℃左右。 管拾取机构包括管采摘室内的高速缓存器,以便将管架从冷冻室快速往复运动到管采集室中。 梭子具有夹紧机构,用于在夹头从机架拾取管时将管架固定到位。 该系统还包括一个推销,当它从管架上被拾取时,其推动相应管子的底部。 管采摘室中包括一维条形码阅读器。 夹持头能够在一维条形码读取器的视野内垂直移动并旋转,以便于识别和读取位于拾取的存储管的侧壁上的一维条形码。 该系统还使用风扇来促进管采摘室的有效冷却。
