Development of cell line mechanism

一个装有卵子和培养液的方形盒子被故意用音圈马达振动，以将这些卵子聚集在所述盒子的中心。然后，用图像处理装置选择符合记忆形状的卵子，并逐个放置在吸管夹持点。在试验中构建了一个具有上述功能的系统，该系统可以自动将任何卵子定位在固定位置，从而缩短了找出卵子并将其定位在固定吸管的过程中的时间。音圈电机由模拟PID控制器控制，将变送器输出的电压与电涡流间隙传感器检测到的位移电压进行比较。小方壳固定在安装在音圈电机轴线上的大方壳内。变送器输入电压波控制音圈电机，震动方壳。这种振动被用来收集卵子。

A square case containing ova and culture medium was vibrated using a voice coil motor on purpose to gather those ova at the center of the mentioned case. Followed by, only those ova which conform to the memorized shape are selected with a picture processing device and are positioned at the point of holding pipette one by one. A system with mentioned functions was constructed on trial.This system can position automatically any ovum at the fixed position, and therefore could shorten the time of the process to search out the ovum and position it at the point of holding pipette.Prepositioning partThe device which shakes the Petri dish and square case filled with medium by using a voice coil motor was made for trial purposes. The voice coil motor is controlled by analog PID controller which compares the voltage from the transmitter with the displacement voltage detected by the eddy current gap sensor. The small square case is fixed in a large square case installed at the axis of the voice coil motor. A voltage wave is inputted by the transmitter to control the voice coil motor, and the square case is shaken. This vibration is used to gather the ova.
