[0045] The above-mentioned loading device is equipped with a material bin 200, a temporary storage channel 300 and a cup drop channel 310 on the cup scooping base plate 100. One end of the temporary storage channel 300 is connected to the cup outlet 210, and the other end is connected to the cup drop channel 310. The reaction cup 900 in the accommodating cavity of the material bin 200 can flow into the temporary storage channel 300 through the cup outlet 210 for temporary storage. A switch mechanism 400 is installed on the temporary storage channel 300, and the switch mechanism 400 controls the opening or closing of the temporary storage channel 300. When the switch mechanism 400 moves along the first direction, the accommodating space 4111 of the switch mechanism 400 is connected with the temporary storage channel 300. At this time, a reaction cup 900 temporarily stored in the temporary storage channel 300 can flow into the accommodating space 4111 of the switch mechanism 400, and then the switch mechanism 400 moves along the second direction, so that the accommodating space 4111 of the switch mechanism 400 is connected with the cup drop channel 310.

[0046] In some embodiments, Figures 1 to 4 As shown, the cup scooping module further includes a lifting member 500, and the lifting member 500 includes a lifting plate 510 and a cup disturbing plate 520 connected to each other. The lifting plate 510 and the cup disturbing plate 520 can both extend into the accommodating chamber to push the reaction cup 900 in the accommodating chamber out to the cup outlet 210, and in the process of the lifting member 500 extending into the accommodating chamber, the lifting member 500 pushes the switch mechanism 400 to move along the first direction. By providing the lifting member 500, the lifting member 500 extends into the accommodating chamber to push the reaction cup 900 out of the cup outlet 210, so that the reaction cup 900 can flow into the temporary storage flow channel 300. Moreover, when the lifting member 500 extends into the accommodating chamber, the lifting member 500 can push the switch mechanism 400 to move along the first direction, so that the accommodating space 4111 of the switch mechanism 400 is connected with the temporary storage channel 300. At this time, a reaction cup 900 temporarily stored in the temporary storage channel 300 can flow into the accommodating space 4111 of the switch mechanism 400.

[0051] In some embodiments, Figures 1 to 4 As shown, the cup scooping module also includes a cup scooping driving mechanism, which includes a first driving source 500. The output end of the first driving source 500 is connected to the lifting member 500.

The moving block 410 moves along the first direction to approach the switch seat 420, so that the receiving space 4111 of the moving block 410 is connected to the temporary storage flow channel 300, and at this time, a reaction cup 900 temporarily stored in the temporary storage flow channel 300 can flow into the receiving space 4111 of the switch mechanism 400. The moving block 410 moves in the second direction, thereby moving away from the switch seat 420, so that the accommodating space 4111 of the moving block 410 is connected to the cup drop channel 310. At this time, the reaction cup 900 in the accommodating space 4111 can fall into the cup drop channel 310 and then be transferred through the cup drop channel 310.

[0058] In some embodiments, Figures 4 to 6 As shown, the switch mechanism 400 also includes a reset member 430, an installation space is provided on the switch seat 420, the moving block 410 is partially provided in the installation space, the end of the reset member 430 is passed through the installation space and connected to the moving block 410, and the reset member 430 can push the moving block 410 to move along the second direction by its own elastic force. As mentioned above, when the lifting member 500 moves in the direction of extending into the accommodating cavity, the lifting member 500 can squeeze and push the moving block 410 to move along the first direction, and the reset member 430 is compressed at this time. When the lifting member 500 moves in the direction of withdrawing from the accommodating cavity, the lifting member 500 is separated from the moving block 410, and at this time, the reset member 430 is elastically reset, thereby pushing the moving block 410 to move along the second direction by its own elastic force.

[0059] In some embodiments, Figures 4 to 6 As shown, the switch mechanism 400 further includes an end plate 440, which is disposed on a side of the switch base 420 away from the moving block 410 and connected to the switch base 420, and one end of the reset member 430 away from the moving block 410 is connected to the end plate 440.

The first baffle 412 and the second baffle 413 are respectively provided on both sides of the receiving space 4111. A plane perpendicular to the arrangement direction of the first baffle 412 and the second baffle 413 is used as a reference plane, and the orthographic projection of the first baffle 412 and the orthographic projection of the second baffle 413 do not overlap on the reference plane. By providing the receiving space 4111 on the body 411, the first baffle 412 and the second baffle 413 are respectively provided on both sides of the receiving space 4111, and the orthographic projection of the first baffle 412 and the orthographic projection of the second baffle 413 do not overlap on the reference plane, so that when the moving block 410 moves along the first direction, the receiving space 4111 is communicated with the temporary flow channel 300, and when the moving block 410 moves along the second direction, the receiving space 4111 is communicated with the cup drop flow channel 310.

The reaction cup 900 in the temporary flow channel 300 is blocked in the temporary flow channel 300 by the first baffle 412 of the moving block 410; when the lifting member 500 rises to the vicinity of the switch mechanism 400, the moving block 410 is pressed by the lifting member 500 to a retracted state as shown in FIG. Figure 4In the state shown, the first baffle 412 of the moving block 410 and the temporary storage channel 300 are staggered, and the reaction cup 900 in the temporary storage channel 300 slides into the accommodating space 4111 of the moving block 410 and is blocked by the second baffle 413 of the moving block 410 (the accommodating space 4111 can only accommodate one reaction cup 900); when the lifting member 500 descends and separates from the moving block 410, the moving block 410 is reset to the extended state (as shown in FIG. 1 ) by the thrust of the reset member 430. Figure 3 As shown in the figure), the first baffle 412 of the moving block 410 blocks the temporary storage reaction cup 900 in the temporary storage flow channel 300, and the second baffle 413 of the moving block 410 is staggered with the cup drop flow channel 310. The reaction cup 900 in the accommodating space 4111 of the moving block 410 slides out along the cup drop flow channel 310, completing a reaction release of the temporary storage flow channel 300.

[0062] In some embodiments, Figure 1 and Figure 2 , Figures 7 to 9 As shown, the cup scooping module also includes a cup receiving channel 320, one end of which is connected to the cup outlet 210, and the other end is connected to the temporary storage channel 300, and the angle between the cup receiving channel 320 and the temporary storage channel 300 is an acute angle; the cup receiving channel 320 is provided with a cup receiving groove 321, and the cup receiving groove 321 is used to accommodate the reaction cup 900, and the bottom end of the reaction cup 900 on the cup receiving groove 321 can pass through the cup receiving groove 321, and the large end of the reaction cup 900 is clamped on the upper end surface of the cup receiving groove 321. By setting the cup receiving channel 320 to connect the cup outlet 210 and the temporary storage channel 300, it is convenient to transport the reaction cup 900 removed from the cup outlet 210 to the temporary storage channel 300. The cup receiving groove 321 is provided on the cup receiving channel 320, so that the reaction cup 900 is vertically arranged in the cup receiving channel 320.

[0072] In some embodiments, Figure 1 , Figure 2 as well as Fig. 9 As shown, the cup transport module further includes a cup presence optical coupler 140 mounted on the cup scooping substrate 100, and the cup presence optical coupler 140 is used to detect whether there is a reaction cup 900 in the cup transporting seat 600 located at one end of the cup receiving flow channel 320 away from the temporary storage flow channel 300. Through the cup presence optical coupler 140 on the cup scooping substrate 100, the cup presence optical coupler 140 is used to detect whether there is a reaction cup 900 in the cup transporting seat 600.
