[0111] Third step: After the glass slide and the pipette 8 are both placed, start this device. The first driving motor 35 in this device drives the glass slide tray 4 and the pipette bracket 5 to rotate synchronously; the liquid dropping monitor 72 corresponds to the positions of the glass slide and the pipette 8, and the opto-coupler switch 71 detects that the glass slide is placed properly. When the glass slide is not placed properly, the light-blocking piece 4322 will block the detection optical path signal transmission between the transmitting end and the receiving end in the opto-coupler switch 71; after the glass slide and the pipette 8 are both placed, a start signal is sent to the liquid dropping unit through the control unit.

[0112] Fourth step: The glass slide support part 42 tilts the glass slide by 25 degrees; the clamping driving mechanism in the liquid dropping unit drives the first nipple clamp and the second nipple clamp to clamp the pipette nipple 82; the pipette nipple 82 is squeezed, and the chromosome test solution in the pipette body 81 drops onto the glass slide; after the liquid dropping is completed, the first driving motor 35 continues to drive the glass slide tray 4 and the pipette bracket 5 to rotate synchronously for the next pipette liquid dropping.

[0113] Fifth step: During the rotation process, when there is no carrier on the dropper support 512 or the glass slide support part 42, the opto-coupler switch 71 and / or the liquid dropping monitor 72 will send a stop signal to make the clamping driving mechanism stop the rotation driven by the first driving motor 35.

[0114] When continuous detection is required, the dropper support 512 is filled with pipettes 8, and the glass slide support part 42 places the glass slide properly. The device will repeat the steps of the third step and the fourth step.
