[0024] Please refer to Figure 3The cleaning and disinfecting mechanism 2 comprises cleaning boxes 21 fixedly installed on the left and right sides of the operation table 10, and motor boxes 22 fixedly installed at the bottom of the cleaning boxes 21. The inner side wall of the motor box 22 is fixedly installed with a motor 23. The inner bottom wall of the cleaning box 21 is rotatably connected with a rotating cylinder 24. The inner wall of the rotating cylinder 24 is fixedly installed with a soft brush 26. A plurality of liquid permeable holes 25 are formed in the bottom of the rotating cylinder 24. The output end of the motor 23 is connected with the rotating cylinder 24. By starting the mechanical arm 11, the pipette head 12 is inserted into the inside of the cleaning box 21, so that the pipette head 12 is immersed in alcohol. Then, by starting the motor 23, the rotating cylinder 24 is driven to rotate, so that the soft brush 26 brushes the pipette head 12. Thus, while being immersed, the gap of the pipette head 12 is brushed and disinfected, so as to avoid stubborn bacteria and viruses remaining in the gap and prevent cross contamination.

[0025] Please refer to Figure 3 One side of the cleaning box 21 is fixedly installed with a water outlet box 27. One end of the water outlet box 27 is fixedly installed with a threaded cylinder 28. The inner wall of the threaded cylinder 28 is threadedly connected with a plug 29. Further explanation is as follows: The cleaning box 21 contains disinfectant or disinfectant alcohol. By manually rotating the plug 29, the plug 29 is separated from the threaded cylinder 28, so that the disinfectant or disinfectant alcohol in the inside of the cleaning box 21 is discharged, thereby achieving replacement.

[0026] The bottom of the operation table 10 is provided with a moving damping mechanism 3. The moving damping mechanism 3 comprises universal wheels 37 for moving.

[0027] Please refer to Figure 4 The moving damping mechanism 3 comprises a sliding frame 31 fixedly installed at the bottom of the operation table 10.

The moving and damping mechanism 3 is used to drive the universal wheel 37 to contact the ground, so that the device can move flexibly and the flexibility is effectively improved.

[0032] The implementation principle of the pipetting equipment based on the mechanical arm in the embodiment of the application is as follows. The cleaning and disinfecting mechanism 2 is used to drive the soft brush 26 to disinfect the surface and gaps of the pipette head 12, so as to prevent cross contamination and affect the accuracy and reliability of experimental results. The moving and damping mechanism 3 is used to drive the universal wheel 37 to contact the ground, so that the device can move flexibly and the flexibility is effectively improved. The mechanical arm 11 is started to drive the pipette head 12 to be inserted into the inside of the cleaning box 21, so that the pipette head 12 is immersed in alcohol. Then the motor 23 is started to drive the rotating cylinder 24 to rotate, so that the soft brush 26 brushes the pipette head 12, thereby brushing and disinfecting the gaps of the pipette head 12 while being immersed. The plug 29 is manually rotated to separate the plug 29 from the threaded cylinder 28, so that the disinfectant or disinfectant alcohol in the inside of the cleaning box 21 is discharged. The damping spring shock absorber 32 is installed to be telescopic, so that the sliding box 33 slides in the inside of the sliding frame 31 to dampen during movement. The electric telescopic rod 36 is started to drive the universal wheel 37 to contact the ground, so that the base 1 is separated from the ground, thereby pushing the device to move.
