[0088] 推动机构 2400, 用于推动样本架 900, 使样本架 900沿着挡板 2300运动, 在此过 程中, 要逐一对样本架 900上每个样本试管进行扫码、 取样, 包括: 推动电机 24 02, 推动电机 2402驱动推动板 2401沿挡板 2300运动 (挡板 2300沿让位槽 2301运 动) , 从而推动样本架 900;
[0089] 阻挡机构 2200, 如图 2-2和 2-3所示, 设置在上料导轨 2101末端, 包括阻挡驱动 部件 2201, 设置在上底板 (上底板通常由安装有挡板 2300和安装有导轨 2101的 两部分组成) 底部的阻挡导轨 2203, 设置在阻挡导轨 2203上的受阻挡驱动部件 2 201驱动而沿阻挡导轨 2203运动而靠近或者远离挡板 2300的阻挡滑块 2202, 所述 阻挡滑块 2202上设置有前挡块 2211和后挡块 2212, 前挡块 2211与后挡块 2212之 间可容纳一个样本架 900, 前挡块 2211和后挡块 2212均具有凸出于上底板的凸起 状态和不凸出于上底板的下降状态, 作为一种具体的实现方式前挡块 2211和后 挡块 2212均设置在弹性件上 (在前挡块 2211和后挡块 2212的转动轴上设置扭簧 ) , 弹性件为前挡块 2211和后挡块 2212提供弹力, 使得前挡块 2211和后挡块 221 2在无其它外力作用下回到凸起状态, 前挡块 2211远离挡板 2300的一面为斜面, 后挡块 2212靠近挡板 2300的一面为斜面, 从而使得样本架 900经过前挡块 2211吋 , 能够将前挡块 2211压下 (使前挡块 2211从凸起状态变为下降状态, 以防止前 挡块 2211阻挡, 样本架 900通过后前挡块 2211立即恢复凸起状态) , 前挡块 2211 和后挡块 2212与阻挡滑块 2202—同运动吋, 后挡块 2212被上底板压下 (后挡块 2 212到达上底板上没有孔洞的位置, 在上底板的板面作用下, 使后挡块 2212从凸 起状态变为下降状态) , 前挡块 2211推着样本架 900紧靠住挡板 2300;
[0090] 下料机构 2500, 如图 2-4所示, 用于将位于挡板 2300末端的样本架 900推到下料 导轨 2102上, 从而使样本架 900能够受下料传输带 2104带动, 推动电机 2501, 推 动导轨 2503, 推动电机 2501驱动摇杆机构 2504从而使推板 2502沿推动导轨 2503 做往复运动, 推板 2502能够穿过让位孔 2303从而推动位于挡板 2300—侧的样本 架 900。
[0091] 本实施例输送装置的运输过程如下: 将样本架 900放置在上料导轨 2101的进料 位置处 (图中右下侧) , 上料传输带 2103运动吋带动样本架 900到达阻挡机构 22 00处 (阻挡机构 2200位于距离挡板 2300最远端的位置) , 首先, 样本架 900会经 过并压下前挡块 2211, 一旦样本架 900越过前挡块 2211, 前挡块 2211凸起, 并将 样本架 900固定在前挡块 2211与后挡块 2212之间。 然后, 阻挡机构 2200处的样本 架 900要等待前一个样本架 900即位于挡板 2300处的样本架 900处理完毕, 一旦前 一个样本架 900处理完毕 (是否处理完毕由传感器来监测, 当传感器感应到挡板 2300处无样本架 900吋, 就会启动阻挡驱动部件 2201) , 阻挡驱动部件 2201就会 运行从而将阻挡滑块 2202连通样本架 900—起带动着靠近挡板 2300, 在此过程中 前挡块 2211压下, 前挡块 2211推着样本架 900紧靠住挡板 2300, 之后, 阻挡滑块 2202返回原位置。 样本架 900紧靠住挡板 2300, 推动机构 2400的推动电机 2402启 动, 推动样本架 900沿着挡板 2300运动逐一对样本架 900上每个样本试管进行扫 码、 取样, 完成后样本架 900被推动到下料机构 2500位置处 (也同吋位于挡板 23 00末端) 。 最后, 下料机构 2500的推动电机 2501启动, 将样本架 900推到下料导 轨 2102上, 下料传输带 2104带动样本架 900到达下料位置 (图中右上侧) 。 阻挡 驱动部件 2201处有无样本架 900也是靠感应器来监测, 若阻挡驱动部件 2201处无 样本架 900, 则会控制上料传输带 2103将一个样本架 900从上料位运输过来。
[0092] 本实施例的样本输送装置, 样本架 900最终由阻挡机构 2200, 特别是由前挡块 2 211和后挡块 2212固定着运输到挡板 2300 (也即取样位置) 处, 通过挡板 2300和 后挡块 2212的固定作用, 能够使样本架 900保持固定姿态。 同吋在挡板 2300处有 样本架 900存在的情况下, 后挡块 2212可以防止下一个样本架 900进入挡板 2300 处, 保证取样依序准确进行。
