Abstract

The invention discloses an injection molding system for a soft chip and a method for manufacturing the soft chip. The injection molding system comprises an adhesive mixing system, an injection mold, an adhesive dispensing system, a defoaming system and a solidification system, wherein the adhesive mixing system is used for mixing soft chip raw materials and feeding the mixed raw materials to the adhesive dispensing system; the injection mold is used for molding the height and the direction of the soft chip, the bottom of the injection mold is provided with a mold plate, and a microstructure pattern is formed on the upper surface of the mold plate; the adhesive dispensing system communicates with the adhesive mixing system, is located above the injection mold and is used for laying the mixed raw materials on the upper surface of the mold plate; the defoaming system is provided with a cavity capable of containing the injection mold and used for conducting overall defoaming on the injection mold after adhesives are applied to the injection mold; the solidification system is provided with a sealed space, and the defoamed injection mold is heated through a heating mode, so that the mixed raw materials are solidified and molded. The injection molding system for the soft chip is small in equipment size and suitable for mass production and use of laboratory chips or workshop chips.

Description

technical field [0001] The application belongs to the technical field of microfluidic chip production, and in particular relates to a soft chip injection molding system and a method for making a soft chip. Background technique [0002] Microfluidics integrates the basic operation units such as sample preparation, reaction, separation, and detection in the biological, chemical, and medical analysis processes into a micron-scale chip to automatically complete the entire analysis process. Due to its great potential in the fields of biology, chemistry, and medicine, it has developed into a new research field interdisciplinary in biology, chemistry, medicine, fluid, electronics, materials, and machinery. [0003] The soft microfluidic chip represented by PDMS (Polydimethylsiloxane, polydimethylsiloxane) has become a widely used microfluidic chip because of its low cost, easy to use, and good chemical inertness. field of polymer materials. The production process of the PDMS chip...
