Abstract

The invention discloses an electrode printing device for a microfluidic chip. The microfluidic chip printing system includes a second conveying component; a cutting component, the cutting component includes a circular film cutter, a cutting roller, The traction roller, the circular film cutter and the cutting roller are arranged correspondingly; through the corresponding cooperation of the circular film cutter and the cutting roller, the electrode sheet and the electrode sheet surrounding are pressed and cut out on the second conveying substrate Yu Ke; the traction roller is far away from the second head end roller. For discharging the remaining material, the present invention uses the printing principle combined with the microfluidic chip manufacturing process to print the microfluidic chip.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to an electrode printing device and a printing method for a microfluidic chip. Background technique [0002] Microfluidic chip is a new interdisciplinary field and an important development frontier in many fields such as analytical science, micro-electromechanical processing, life science, chemical synthesis, analytical instruments and environmental science in the new century. [0003] The processing technology of microfluidic analysis chips originated from the microfabrication of semiconductor and integrated circuit chips, but the processing size of the chip channel is much larger than that of large-scale integrated circuits. The size of the chip is about a few square centimeters, and the width and depth of the microchannel are on the order of microns. On the other hand, the selection of chip materials, the design of microchannels, the surface modification of microchannels an...

Problems solved by technology

[0004]In the prior art, in the microfluidic chip processing technology, there are mainly methods such as laser engraving, chemical etching, and photolithography. These methods have their own advantages and disadvantages. The disadvantages are complex operation, long processing cycle, material selection, large channel roughness, and poor repeatability, and it is difficult to produce in batches, so it is difficult to be used as a general and effective chip processing method

With the development of modern numerical control micromachining technology, its processing accuracy and scale can meet the technical requirements of microfluidic chips, but the existing numerical control micromachining equipment is not designed for the design and processing of microfluidic chips , causing unnecessary waste and destruction of materials in application

[0005]Therefore, there is still a lot of room for development in the existing technology
