Abstract

The invention discloses a liquid injection pump driving device for a microfluidic control system, which mainly includes: an integrated board, a driving mechanism, a zero plate, a photoelectric sensor, a PCB board, and an output shaft; a control circuit with a motor is installed on the integrated board The PCB board, the driving mechanism and the corresponding photoelectric sensor; the driving mechanism is composed of a motor, a reducer, and an output shaft; the motor drives the output shaft to rotate through the reducer, wherein The output shaft is equipped with the zero position sheet, and the initial position of the output shaft rotation and the end position after a certain number of rotations are detected by the photoelectric sensor; the advantage of the present invention is that the driving mechanism can be used in a single group or in multiple groups Arranging side by side improves the efficiency of use, and through the cooperation of the motor and the reducer, the pressure supply and stability of the system can be improved. At the same time, the coordination of the zero plate and the photoelectric sensor can improve the system's liquid absorption and Draining accuracy.

Description

technical field [0001] The invention relates to the field of biochemical analysis equipment, in particular to a liquid injection pump driving device for a microfluidic control system. Background technique [0002] Microfluidics is a system that uses micropipes to process or manipulate tiny fluids. Microfluidics can achieve a series of microfabrication and microoperations that are difficult to complete by conventional methods. At present, microfluidic chips have been widely used in technical fields such as digital PCR and gene sequencing. Among them, the infusion pump (syringe pump) in the microfluidic system is an important device to complete the pushing or drawing of the liquid sample to be transferred. Among them, the driving device of the pump is a key factor that directly affects the pushing and pumping pressure and the accuracy of liquid delivery. In the prior art, the diameter of the microchannel for transmitting the sample droplet in the microfluidic chip is general...
