下面介绍本发明的工作原理:
1、 取液机构的工作原理:
如图 3所示的取液机构, 工作时, 第一电机 122带动同步轮 123 转动从而使同步带 124做同步运动, 此时针夹 1 14央持针头 1 1 1, 针 夹 1 14和同步带 124连接, 同时, 针夹 1 14也连接第一滑块 127, 因
此在同步带 124运动的过程中将会带动针夹 1 14沿着第一滑轨 125上 下运动, 进一步实现配液针 1 1整体上下运动。
2、 导向机构的工作原理:
第二电机 21正转时 , 带动丝軒套 23向上运动, 从而带动导向板 24以支点部 241 为旋转中心逆时针旋转, 同时, 由于取液机构 1通过 第二滑块 5与侧板 6上的第二导轨 4移动连接, 分合导向轮 3将按照 导向槽 241 的路径运动, 从而实现取液机构 1 向左移动, 四个配液针 1 1 的间距将会变大, 实现取液机构 1 的分离。
第二电机 21反转时, 带动丝杆套 23向下运动, 从而带动导向板 24以支点部 241 为旋转中心顺时针旋转, 同时, 由于取液机构 1通过 第二滑块 5与侧板 6上的第二导轨 4移动连接, 分合导向轮 3将按照 导向槽 241 的路径运动, 从^实现取液机构 1 向右移动, 四个配液针 1 1 的间距将会变小, 实现取液机构 1 的聚合。
通过上述技术方案, 本发明技术方案的有益效果是: 一种配液机 构, 导向机构的设置, 能够有效的控制配液针间距, 运行效率高, 响 应速度快; 分合导向轮与导向槽匹配安装运行, 导向作用好; 移动机 构的设置, 实现了配液针的上下移动, 使配液针上下移动更为方便; 配重机构的设置, 使得即使在设备断电的情况下, 配液针也不会由于 自重 ¾向下掉落。
对所公开的实施例的上述-说明, 使本领域专业技术人员能够实现 或使用本发明。 对这些实施例的多种修改对本领域的专业技术人员来 说将是显而易见的, 本文中所定义的一般原理可以在不脱离本发明的 精神或范围的情况下, 在其它实施例中实现。 因此, 本发明将不会被 限制于本文所示的这些实施例, 而是要符合与本文所公开的原理和新 颖特点相一致的最宽的范围。
