Abstract

The invention discloses a modular microfluidic chip clamp based on magnetic link. The modular microfluidic chip clamp includes: a base plate, a thickness adjustment module, a positioning module and acover plate. By embedding a permanent magnet material to the base plate and the cover plate, the connection of all parts can be realized by relying on magnetic force, by setting positioning holes at four corners of the above components, the installation precision is guaranteed by guide pillars. Two rectangular grooves are symmetrically arranged on the base plate for chip insertion and installation, and by machining positioning scale in the grooves and machining positioning holes on the positioning module, the connection precision can be ensured during magnetic joint insertion. By replacing anadjustment plate, installation of chips with different thicknesses can be realized. The grooves and bosses are disposed on both sides of the base plate respectively to guarantee the positioning of multiple clamp connection, the embedded permanent magnet material is exposed at the bottoms of the grooves, and the clamp is linked to the magnetic force of the permanent magnet material through the metal base plate. The device has the characteristics of simple structure, easy adjustment, disassembly and assembly, and convenient use.

Description

technical field [0001] The invention belongs to the technical field of microfluidic chips, and in particular relates to a modular microfluidic chip fixture based on magnetic links, which can realize rapid modular construction and adjustment of a multi-chip microfluidic test platform. Background technique [0002] Microfluidic technology is a technology for studying, processing and controlling nano-micron-sized fluids. It can control and transmit fluids with a volume of picoliters or even nanoliters in a microchannel structure that reaches microns or even nanometers on the least one-dimensional scale. quality. Microfluidic chips, as one of the most active frontiers in the development of microfluidic technology, can integrate analysis functions such as sampling, separation, and detection into a few centimeters of chips, and have been widely used in modern biochemical analysis, instant diagnosis, high-tech Throughput screening and other fields. [0003] Microfluidic chips are...
