[0028] The utility model provides a kind of front-end processing station, it can be as the organic detection station of organic project such as melamine, sorbic acid, benzoic acid, acesulfame-k, also can be as the inorganic detection station of inorganic project such as total arsenic, total mercury project of heavy metal, pollutant lead, chromium project, physical and chemical index calcium, sodium, zinc project etc. Specifically, as Figures 1 to 5As shown, the front-end processing station includes an experimental table 10, a robot 20, a pipette module 30, a peristaltic pump module 40, a constant volume instrument 50, and a cap opening and closing machine 60. The experimental table 10 has a vessel placement area 11 for placing detection containers. The robot 20, the constant volume instrument 50, and the cap opening and closing machine 60 are fixed to the experimental table 10. The pipette module 30, the constant volume instrument 50, and the cap opening and closing machine 60 are sequentially arranged around the circumference of the robot 20, and the cap opening and closing machine 60 is located beside the vessel placement area 11. The pipette module 30, the peristaltic pump module 40, and the constant volume instrument 50 are adjacently arranged on the experimental table 10. The operating end of the robot 20 is used to pick up a detection container from the vessel placement area 11 and move it to the pipette module 30, the peristaltic pump module 40, or the constant volume instrument 50 for preset operations. The cap opening and closing machine 60 is used to open the cap of the detection container picked up by the robot 20 and close the cap after constant volume.

[0029] The peristaltic pump module 40, the constant volume instrument 50, and the pipette module 30 all have the function of adding reagents for constant volume. Among them, the constant volume precision of the peristaltic pump module 40, the pipette module 30, and the constant volume instrument 50 is different, and they complement each other to improve detection accuracy and adapt to diversified needs.

For example, Figure 2 and Figure 4 As shown, the peristaltic pump module 40, the constant volume instrument 50, and the pipette module 30 are centrally arranged on the same side of the robot 20, which facilitates the robot 20 to pick up a detection container and perform subsequent operations in the same area. Specifically, the vessel placement area 11 and the peristaltic pump module 40 are located on different sides of the robot 20, and the robot 20 moves from one side to the other side to perform subsequent operations after picking up a detection container. Alternatively, the vessel placement area 11, the peristaltic pump module 40, the constant volume instrument 50, and the pipette module 30 are located on the same side of the robot 20, and the vessel placement area 11 is closer to the robot 20 than the peristaltic pump module 40, the constant volume instrument 50, and the pipette module 30. The robot 20 sequentially completes the picking and reagent adding operations.

[0030] In an embodiment, one of the peristaltic pump module 40, the constant volume instrument 50, and the pipette module 30 is used to add reagents to the detection container. In another embodiment, the peristaltic pump module 40, the constant volume instrument 50, and the pipette module 30 cooperate to complete the reagent addition. For example, the peristaltic pump module 40 and the pipette module 30 can quickly add reagents to the detection container, serving as instruments for preliminary reagent addition; and the constant volume instrument 50 can serve as the last fine constant volume instrument. In this way, through the cooperation of the constant volume instrument 50 and the peristaltic pump module 40 and the pipette module 30, accurate constant volume is achieved.

[0031] As shown, Figure 1 and Figure 2As shown, the cap opening and closing machine 60 adopts an existing cap opening and closing machine, the specific structure of which is prior art and will not be described in detail. The cap opening and closing machine 60 has the functions of opening and closing the cap. For the detection container with a cap, the robot 20 first moves to the cap opening and closing machine 60 to open the cap after picking up the detection container from the vessel placement area 11, and then moves to the peristaltic pump module 40, the constant volume instrument 50 or the pipette module 30 to add reagents, and covers the detection container through the cap opening and closing machine 60 after the operation is completed, so as to facilitate the flow to the next detection station and ensure the safety of the sample to be tested in the detection container. For the detection container without a cap, the robot 20 directly moves to the peristaltic pump module 40, the constant volume instrument 50 or the pipette module 30 to add reagents after picking up the detection container from the vessel placement area 11, and determines whether to move to the cap opening and closing machine 60 for closing operation according to the related requirements of the detection item.
