Problems solved by technology

[0003] In biological experiments, when injecting, transporting, and merging liquids in the current technology, manual transfer of liquids takes up 30% of the time of the entire experiment. This task is not only tedious, but also prone to mistakes. Moving or rotating processing equipment affects efficiency
In addition, a huge amount of experimental waste will be generated during the pipetting process, such as pipette tips, etc.
Therefore, the methods and equipment of the prior art are difficult to meet the requirements of injecting, transporting and fusing liquids

Abstract

The invention discloses a system for non-contact multi-focus ultrasonic phased array suspension pipetting. The system comprises a computer module, a PWM control module, an adjustable stabilized voltage supply module, a driving module, an ultrasonic array module and a liquid drop generation module; the computer module sends a received instruction to the PWM control module, and the PWM control module calculates a PWM wave frequency and a PWM wave duty ratio corresponding to the instruction; the logic input channel of the driving module is controlled according to the PWM wave frequency and the PWM wave duty ratio obtained by calculation; the adjustable stabilized power supply module provides an amplification power supply for the driving module, so that the output port of the driving module generates PWM waves with the same voltage amplitude as the adjustable stabilized power supply module, and the PWM waves generated by the output port of the driving module are input into the ultrasonic array module or the liquid drop generation module; the ultrasonic array module generates a vibration and standing wave sound field after receiving the PWM waves to realize liquid drop suspension; and after the liquid drop generation module receives the PWM waves, the capture and transfer of the liquid drops are realized.

Description

technical field [0001] The invention relates to the technical field of ultrasonic processing equipment, in particular to a non-contact multi-focus ultrasonic phased array suspension pipetting method and system. Background technique [0002] Ultrasonic standing wave levitation technology uses the radiated sound pressure generated by ultrasonic vibration to make the suspended body suspend or move in the sound field without any additional effects, and has the characteristics of non-contact and container-free levitation. Ultrasonic standing waves are used in fields such as microelectromechanical systems, biomedical engineering, pharmaceuticals, and containerless material handling and preparation. Ultrasonic control can achieve constant speed movement and stable flipping of MEMS parts. Under the condition of non-contact operation, the precise assembly of MEMS can be completed without damaging the micropatterns on the surface of MEMS parts. In pharmaceutical analysis, the sample ...
