[0032] The main working principle of the reaction cup automatic loading device of the utility model is as follows: the picking driving device 22 drives the picking disk 21 to rotate, and during the rotation of the picking disk 21, the grabbing hook 212 of the picking claw 211 of the picking disk 21 will hook the reaction cup in the reaction cup hopper 1; and as the picking disk 21 rotates, the picking claw 211 and its grabbing hook 212 will enter the feeding section 31 of the guide channel 3 and then exit the feeding section 31 of the guide channel 3. In this process, the reaction cup hooked by the grabbing hook 212 will remain in the feeding section 31 of the guide channel 3 under the action of inertia, and the reaction cup entering the feeding section 31 of the guide channel 3 will be output to the reaction cup buffer device 4 along the discharging section 32 of the guide channel 3 under the action of gravity, so that the reaction cup is loaded into the reaction cup buffer device 4. Among them, the utility model hooks the reaction cup by the grabbing hook 212 of the rotating dial 21 and sends the reaction cup into the feeding section 31 of the guide channel 3, so that the reaction cup can be directed to enter the guide channel 3, and the guide channel 3 guides the reaction cup so that the reaction cup is accurately output to the reaction cup buffer device 4; it can be seen from the above that the utility model can realize the automatic directional loading of the reaction cup into the reaction cup buffer device 4, which helps to improve the detection efficiency of the immunoassay analyzer.

The working mode of the reaction cup storage device 6 is as follows: in normal state, the reaction cups in the reaction cup bin 61 are accumulated on the belt of the feeding conveyor 62; when the reaction cups need to be added to the reaction cup hopper 1, the feeding conveyor 62 operates to drive the reaction cups in the reaction cup bin 61 to move and make the reaction cups push the elastic baffle 63 so that the elastic baffle 63 is deformed to open the feeding port 611, so that the feeding conveyor 62 can drive the reaction cups to pass through the feeding port 611, and the reaction cups passing through the feeding port 611 enter the reaction cup hopper 1 under the drive of the feeding conveyor 62; when the feeding conveyor 62 does not work, the elastic baffle 63 will reset and close the feeding port 611, so that the reaction cups in the reaction cup bin 61 do not enter the reaction cup hopper 1.

The hopper refill switch 11 can be an infrared proximity switch. When the reaction cups in the reaction cup hopper 1 can trigger the hopper refill switch 11, it is monitored that the reaction cup hopper 1 does not need to be supplemented with reaction cups; and when the hopper refill switch 11 is not triggered, it is monitored that the reaction cup hopper 1 needs to be supplemented with reaction cups.
