[0054] However, this operation is low in efficiency and high in labor cost.

[0055] The utility model provides a kind of detection tool.

[0056] Please refer to Figure 1 、 Figure 2 In an embodiment of the utility model, the detection tool comprises:

[0057] The rack 100;

[0058] The needle placement rack 200, the weighing device 300, the liquid storage part and the waste box 400 are arranged on the rack 100, the needle placement rack 200 is used for placing the needle 210, the liquid storage part is arranged on the weighing device 300, further, the weighing device 300 can obtain the liquid change amount in the liquid storage part; further, in some embodiments, the weighing device 300 is configured as an electronic balance, wherein the liquid storage part can adopt a liquid storage bottle. Specifically, in some embodiments, the liquid storage bottle containing liquid is placed on the electronic balance, and then the electronic balance is zeroed, at this time, after the liquid in the liquid storage bottle is extracted, the electronic balance displays the weight of the missing liquid (the amount of extracted liquid), at this time, the electronic balance can display a negative value, so that the weighing device 300 can obtain the liquid change amount in the liquid storage part by the above method.

[0059] The method is not limited thereto, and in some embodiments, the liquid storage bottle containing liquid is placed on the electronic balance, the electronic balance obtains the weight of the liquid storage bottle and the liquid, or the weight of the liquid in the liquid storage bottle, then the electronic balance weighs the remaining liquid after the liquid in the liquid storage bottle is extracted, and then the difference (the amount of extracted liquid) is calculated according to the two weight values. In this way, the weighing device 300 can obtain the amount of change of the liquid in the liquid storage part by this method.

[0060] The mounting frame 500 is mounted on the rack 100 by a driving mechanism, and is provided with a needle taking position, a liquid extracting position, and a waste material discarding position relative to the rack 100. The mounting frame 500 is provided with a mounting position for detachably mounting the liquid extracting assembly 700. Further, in some embodiments, the liquid extracting assembly 700 can also use other sample adding needles with a pipetting function or samplers with a quantitative sampling function. Specifically, the driving mechanism can drive the mounting frame 500 to move relative to the rack 100. When the driving mechanism drives the mounting frame 500 to move to the needle taking position, the liquid extracting assembly 700 can take out the needle 210. When the driving mechanism drives the mounting frame 500 to move to the liquid extracting position, the liquid extracting assembly 700 can extract the liquid in the liquid storage part through the needle 210. When the driving mechanism drives the mounting frame 500 to move to the waste material discarding position, the liquid extracting assembly 700 can discard the used liquid taking needle into the waste material box 400. It can be understood that when the precision of the liquid extracting assembly 700 is detected, the liquid extracting assembly 700 is first mounted on the mounting position.

Then, the liquid extracting assembly 700 takes the needle, and the needle 210 used for liquid extraction is connected to the liquid extracting assembly 700. Then, the driving mechanism drives the mounting frame 500 to move to the liquid extracting position. Then, the liquid extracting assembly 700 quantitatively extracts the liquid in the liquid storage part through the needle 210. Since the weight of the liquid in the liquid storage part changes, the weighing data of the electronic balance also changes. The difference obtained by the change is the weight value of the liquid extracted by the liquid extracting assembly 700. The weight value is compared with the quantitative extraction value of the liquid extracting assembly 700. In this way, the extraction precision of the liquid extracting assembly 700 can be determined. After the precision error is obtained, the driving mechanism drives the mounting frame 500 to move to the waste material discarding position, and the liquid extracting assembly 700 discards the needle 210 into the waste material box 400. Further, since the liquid extracting assembly 700 is detachably connected to the mounting position, the liquid extracting assembly 700 can be quickly mounted in the mounting position at this time. That is, when the precision of the liquid extracting assembly 700 is detected, the liquid extracting assembly 700 can be quickly mounted in the mounting position. Then, the driving mechanism drives the mounting frame 500 to move in the needle taking position, the liquid extracting position, and the waste material discarding position, thereby driving the liquid extracting assembly 700 to perform a series of automatic operations from needle taking, liquid extraction, weighing to needle discarding. This can reduce human resources and improve efficiency, thereby solving the technical problems existing in the prior art.
