Optical detection assembly of fluorescence immunochromatography analyzer

The utility model provides an optical detection assembly of a fluorescence immunochromatography analyzer, which comprises a support, a sliding mounting frame, an optical detection module, a motor, a gear and a rack, the sliding mounting frame is slidably connected with the support along the front-back direction, and the motor and the optical detection module are fixedly mounted on the sliding mounting frame. The optical detection module comprises an optical detection base, a laser emitter, a photoelectric detector, a dichroscope, an optical filter and a convex lens, laser emitted by the laser emitter is reflected by the dichroscope and then is focused on a detection line and a quality control line on the test strip through the convex lens, and fluorescence excited by the detection line and the quality control line on the test strip penetrates through the dichroscope; stray light except the fluorescence wavelength is filtered by the optical filter and then is received by the photoelectric detector.
