Description

Technical Field

[0001] This utility model relates to the field of in vitro diagnostic equipment technology, specifically to a reagent card handling mechanism for a fluorescence analyzer. Background Technology

[0002] A fluorescence immunoassay analyzer is a highly sensitive in vitro diagnostic device that combines immunochromatography and fluorescence detection technologies. It is widely used in medical testing, food safety, and environmental monitoring. Its technological background and development involve the interdisciplinary integration of multiple fields.

[0003] Existing reagent card handling mechanisms suffer from insufficient positioning accuracy, poor gripping stability, and low efficiency.

[0004] The fluorescence immunoassay analyzer is equipped with a reagent card compartment and an incubation compartment. After the reagent card is ejected from the reagent card compartment for sample loading, it is transported to the incubation compartment by a reagent card transport mechanism for incubation. After incubation, the reagent card transport mechanism transports the reagent card from the incubation compartment to the detection position. This reagent card transport mechanism can stably and accurately grasp and transport the reagent card. However, the positioning accuracy of reagent card transport mechanisms currently on the market is insufficient, which can easily cause the reagent card to shift when inserted into the incubation compartment, affecting the detection results. At the same time, the grasping stability is poor, and traditional grippers are prone to loosening under vibration or temperature changes. Multi-step transport requires manual intervention, resulting in low efficiency and difficulty in meeting the needs of high-throughput detection. Utility Model Content
