The lower end of the electric cylinder 8 extends through the bottom plate of the electric cylinder mounting plate 9 and is connected to a motor mounting plate 17. A liquid receiving pan stepper motor 19 is mounted on the motor mounting plate 17. The output end of the liquid receiving pan stepper motor 19 is connected to one end of a liquid receiving pan mounting bracket 18.

Dyeing: Servo motor 1 4 and servo motor 2 7 are controlled to drive the Y-axis synchronous belt module 3 and the X-axis synchronous belt module 6 to move the syringe 21 to the top of the empty dye bottle 2; the liquid receiving tray stepper motor 19 controls the liquid receiving tray 20 to rotate 90 degrees in the opposite direction to leave the bottom of the syringe 21. The screw stepper motor 14 is operated to drive the Z-axis screw module 10 to move the power claw 11 downward, thereby driving the piston rod 21-1 downward, squeezing the piston rod 21-1 to inject the dye into the empty dye bottle 2, and then completing one distribution; The syringe 21 returns: the liquid receiving tray stepper motor 19 controls the liquid receiving tray 20 to rotate 90° to the bottom of the syringe barrel of the syringe 21; then the servo motor 1 4 and the servo motor 2 7 are controlled to work, driving the Y-axis synchronous belt module 3 and the X-axis synchronous belt module 6 to return the syringe 21 to the top of the dye bottle 2 for taking the dye liquid, and the liquid receiving tray stepper motor 19 controls the liquid receiving tray 20 to rotate 90° in the opposite direction to leave the bottom of the syringe barrel of the syringe 21, and the electric cylinder 8 drives the lower electric claw 12 to move down to a fixed position again, and the upper electric claw 11 and the lower electric claw 12 are released synchronously, and the syringe 21 is put back into the bottle mouth of the dye bottle 2 for taking the dye liquid; then the above process is repeated for the next distribution.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The design of the Y-axis synchronous belt module and the X-axis synchronous belt module enables fast operation and high precision, while also enabling effective and precise positioning over a long travel range. The Z-axis lead screw module, combined with the upper and lower electric grippers, not only ensures high precision, but also ensures the accuracy of the upper electric gripper grabbing the syringe to absorb and discharge liquid, ensuring accurate pipetting. The design of the micro switch avoids the position error caused by the piston rod error during the downward movement of the upper clamping jaw, which may affect the clamping failure of the upper clamping jaw. When the micro switch touches the top cap of the piston rod, the upper gripper starts to grasp. Due to its outward expansion structure, it ensures accurate grasping within the allowable error range. The liquid collecting tray is controlled by a stepper motor, which can collect dripping liquid at the bottom of the syringe to avoid dripping of dye. The liquid collecting tray is detachable for easy cleaning.
