The invention discloses a novel magnetic separation mechanism. The novel magnetic separation mechanism comprises a coding turntable mechanism, a magnet opening and closing mechanism and washing mechanisms, wherein the magnet opening and closing mechanism is mounted on the coding turntable mechanism; the washing mechanisms are distributed at the periphery of the coding turntable mechanism; the magnet opening and closing mechanism is used for controlling a magnet to adsorb nano magnetic beads in liquid of a reaction cup on the coding turntable mechanism; the washing mechanisms are used for washing the liquid in the reaction cup to separate the nano magnetic beads. By virtue of the novel magnetic separation mechanism, multi-station separation and washing are carried out by the same mechanism; a uniform mixing station is arranged; the action process of one station and the action processes of other stations can be simultaneously carried out; a magnetic particle mixing mechanism does not need to be arranged outside the mechanism; by virtue of the rotation movement of the coding turntable plate, the magnetic particles can be uniformly mixed according to the principle of the cam movement and the principle of eccentric rotation, so that the action processes are achieved; the novel magnetic separation mechanism is simple in structure; and the separation and washing efficiency of the device is improved.
