Background

The micro-pore plates are commonly used for mixing in medical treatment, laboratories and scientific research, and most of the prior micro-pore plates are used for mixing by sucking and spitting liquid and realizing mixing by eccentric rotation movement: the eccentric rotation operation realizes the mixing effect by utilizing the eccentric rotation movement of the plane of the micro-pore plate, and in the existing structure, a driving mechanism is generally used for driving the eccentric shaft which is specially processed and manufactured to move through a synchronous belt structure, the eccentric shaft which is directly driven by a motor is a driving shaft, and the eccentric rotation of the driving shaft drives the whole eccentric rotation movement of the micro-pore plate.

However, when the mode is adopted, as the upper optical axis and the lower optical axis of the eccentric shaft are required to have certain eccentric distances, the processing technology is complex, the processing cost is increased, and the eccentric shaft is too long, the upper optical axis and the lower optical axis are difficult to ensure the coaxiality during processing due to the effect of the eccentric distances, and the influence of the coaxiality can cause the blocking in the mixing process; on the other hand, when the motor is assembled, the motor and the active eccentric shaft are connected through the synchronous belt, so that the active eccentric shaft is easy to incline due to the pulling of the synchronous belt during the assembly, and the whole mechanism is blocked during high-speed operation in severe cases, so that the use is inconvenient.
