Abstract

The invention discloses a precise locating device for tip trays. A convex edge is arranged at one side of the tip tray, and a first notch groove and a second notch groove are arranged on the convex edge side by side. The precise locating device comprises a base plate on which a plurality of reflection optical couplers for recognizing the tip trays are arranged; a first locating optical coupler, a second locating optical coupler and a third locating optical coupler are sequentially arranged at one side of the base plate horizontally side by side, and are opposite to the convex edge in the same lateral direction; and a distance between the first notch groove and the second notch groove is equal to that between the first locating optical coupler and the third locating optical coupler. The precise locating device for tip trays is safe, reliable, convenient and efficient, and can rapidly and precisely locate the tip trays.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an accurate positioning device for a suction head tray. Background technique [0002] Chemiluminescence immunoassay analyzer is a new type of labeled immunoassay technology that combines chemiluminescence or bioluminescence with immune reaction to detect trace antigens or antibodies. The suction head of the chemiluminescence immunoassay analyzer is loaded continuously, which can cooperate with the sampling system of the automatic chemiluminescence immunoassay analyzer to complete the addition of blood samples. Among them, before the suction head can be loaded continuously, it is necessary to precisely position the suction head tray. Once the positioning is not accurate, the phenomenon of chucking will occur, resulting in the failure of the subsequent action process to proceed normally. Contents of the invention [0003] Aiming at the deficiencies in the above techn...
