AI Technical Summary

Technical Problem

The magnetic sleeve support of existing nucleic acid extractors is too heavy, making the movement process cumbersome and noisy, which affects the nucleic acid extraction effect and increases the cost.

Method used

Design a nucleic acid extractor with automatic loading and unloading of magnetic rod sleeves. The instrument employs a stage mechanism, a gantry frame, and an actuator. The magnetic rod assembly and reagent tubes move synchronously or relative to each other through a rod drive mechanism. The magnetic rod assembly and reagent tubes are fixed by the radial expansion force of the tension ring. The automatic loading and unloading of the magnetic rod sleeves is achieved in conjunction with the disassembly mechanism.

Benefits of technology

The simplified structure reduces the weight of the magnetic sleeve support, improves work efficiency, reduces noise, ensures the accuracy and purity of nucleic acid extraction, and enhances the automation level and operational efficiency of the equipment.

Abstract

The application discloses a nucleic acid extractor capable of automatically loading and unloading a magnetic rod sleeve, and belongs to the technical field of nucleic acid extraction equipment. A gantry is arranged above a carrier mechanism, and an executing mechanism is arranged on the gantry. The executing mechanism comprises a first carrier rod, a second carrier rod, a carrier rod driving mechanism and a removing mechanism. The second carrier rod below is in tight cooperation with the radial expansion of the reagent tube mouth through a tension ring, so that stable pickup and fixation of the reagent tube are realized. The structure is simple and compact, has strong adaptability to the reagent tube, and is not prone to damaging the reagent tube. The removing mechanism is in abutting cooperation with the reagent tube through a plate body slot, cooperates with the lifting movement of the second carrier rod, can efficiently and automatically complete the removing operation of the reagent tube, does not need manual intervention, and improves the automation level and operation efficiency of the equipment.
