Multi-channel electric fluid jet scanning system

Abstract

The invention discloses a multi-channel electric fluid jet scanning system which comprises a machine stand scanning and moving device and a jet gun fixing and switching system, wherein a machine stand can move in an X direction and a Y direction; the distance between the machine and a jet gun can be adjusted; the jet gun fixing and switching system comprises rotary brackets, jet nozzle brackets and micro injection heads; the rotary brackets are mounted on a fixing device; the jet nozzle brackets are mounted on the rotary brackets; the micro injection heads are connected with the jet nozzle brackets; and a plurality of jet nozzle brackets are mounted on the periphery of each rotary bracket or a plurality of micro injection heads are mounted on each jet nozzle bracket, so that the effect of jetting different liquids at the same position is realized. The multi-channel electric fluid jet scanning system provided by the invention adopts a multi-channel electric fluid jet scanning technology, the sample preparation rate and sample capacity of the multi-channel electric fluid jet scanning system are both 1-2 orders of magnitude higher than those of a traditional piezoelectric-control jet instrument, and the minimum characteristic sample size can reach a submicron level so as to realize a real combined chip at a micro-nanometer device level.

Description

technical field [0001] The invention relates to the field of material genetic engineering, in particular to a multi-channel electrofluid jet scanning system. Background technique [0002] At present, material genome technology has become a revolutionary new material research and development technology at home and abroad, effectively accelerating the process of materials from research to application. The promotion of material genome engineering technology requires special equipment for new material genetic engineering technology.

AI Technical Summary

Problems solved by technology

[0005] The key technical defects of the currently used jet printing equipment mainly lie in: firstly, the working accuracy of the piezoelectric jet technology is greatly affected by the size of the nozzle and the properties of the liquid, and limited by the viscosity of the liquid, the droplet with too small size is easy to be stuck on the needle. Formation of hysteresis; secondly, the piezoelectric vibration process often affects the change of the shape of the droplet, resulting in the highest resolution of the printed pattern can only reach 20-30μm, and the conventional working scale is above 100μm; thirdly, the piezoelectric control jetting technology is still Focusing on controlling the number of droplets, it is obviously difficult to meet the requirements of complex device technology for multi-dimensional pattern printing based on points, lines, and surfaces in terms of preparation accuracy and pattern control
