Abstract: The present invention discloses a full-automatic chemiluminescence immunoassay analyzer, which relates to the field of luminescence analysis equipment. The analyzer of the present invention includes a reaction tube module, a sample tube module, a kit module, a three-dimensional mechanical arm module, a test tube fetching gripper apparatus, a blending structure, an incubator, a washing apparatus, an electric control part and a PC control end. The three-dimensional mechanical arm module includes an X-axis mechanical arm, a Y-axis mechanical arm and a Z-axis mechanical arm, and the bottom of the Z-axis mechanical arm is provided with a sampling needle. The present invention utilizes the test tube fetching gripper apparatus to substitute the original tube fetching and placing apparatus, thereby reducing the cost and improving the moving stability of reaction tubes.
