For example, when encountering an emergency sample, individual urgent loading cannot be realized, resulting in reduced detection efficiency;

Sample container recycling mode is backward, and there is a risk of contamination: most existing sample processing systems use mechanical arm grabbing or manual recycling to handle the sample containers after detection, which is low in safety and easy to cause damage to the sample containers and spillage of residual samples, posing a risk of cross contamination;

[0006] 3. Low integration of sample processing system, complex operation: existing sample processing systems often independently design function modules such as sample loading, detection and sample container recycling, and cannot automatically connect and transition the sample loading, detection and sample container recycling processes on one device, making it impossible to realize fully automatic sample loading, detection and sample container recycling, resulting in low system integration, complex operation process and difficulty for users to use and maintain.

[0087] Embodiment one

[0088] As Figures 2 to 6The utility model provides a device for sample loading and unloading, which comprises a moving mechanism 1 and an execution mechanism 2. The moving mechanism 1 is arranged between a loading device 10, a detection equipment 11 and a recovery device 12 of a sample detection system. The execution mechanism 2 is arranged on the moving mechanism 1. The moving mechanism 1 is used to drive the execution mechanism 2 to move between a first station, a second station and a third station. The first station is the position of the loading device 10 or a position close to the loading device 10. The sample container 3 in the loading device 10 can be clamped at this position. The second station is the position of the detection equipment 11 or a position close to the detection equipment 11. The measured sample container 4 in the detection equipment 11 can be clamped and removed at this position, and the sample container 3 to be measured can be placed into the detection equipment 11. The third station is the position of the recovery device 12 or a position close to the recovery device 12. The measured sample container 4 removed can be put into the recovery device 12 at this position.

[0089] It should be noted that the positions of the first station, the second station and the third station are only named according to the different actions of the execution mechanism 2, and are not specific to the movement of the execution mechanism 2 to different spatial positions. For example, when the positions of the first station, the second station and the third station are close, the execution mechanism 2 can always be in a specific position without moving, and only the conversion action facing different stations can be performed at the specific position. In this case, the moving mechanism 1 does not need to move the execution mechanism 2 to different spaces. When a large number of detection requirements need to be met, the movement of the detection equipment 11 can meet the detection of a large number of sample containers 3 to be measured and the clamping and removal of the measured sample containers 4. When the positions of the first station, the second station and the third station are far apart, the moving mechanism 1 needs to drive the execution mechanism 2 to different stations to perform corresponding actions.

[0090] The execution mechanism 2 has at least a first gripper 201 and a second gripper 202. The first gripper 201 is used to clamp the sample container 3 to be measured in the loading device 10 when the execution mechanism 2 moves to the first station, and to place the sample container 3 to be measured into the detection equipment 11 when the execution mechanism 2 moves to the second station. The second gripper 202 is used to clamp the measured sample container 4 in the detection equipment 11 when the execution mechanism 2 moves to the second station, and to put the measured sample container 4 into the recovery device 12 when the execution mechanism 2 moves to the third station. It should be noted that the first station and the third station can be located in adjacent positions. While the first gripper 201 clamps the sample container 3 to be measured in the loading device 10, the second gripper 202 can put the measured sample container 4 into the recovery device 12.

In addition, the whole process reduces manual operation as far as possible, solves the problem that manual operation is easy to make mistakes, and there is cross contamination risk, improves the safety of sample detection.

After the sample container 3 for measuring is put into the detection equipment 11, the door 111 needs to be closed. Therefore, the execution mechanism 2 in the utility model also has an opening structure 203 and a closing structure 204. The opening structure 203 is used to open the door 111 of the detection equipment 11 when the execution mechanism 2 moves to the second station. The closing structure 204 is used to close the door 111 of the detection equipment 11 when the execution mechanism 2 moves to the second station.

[0094] The second clamping jaw 202 that clamps the sample container 4 can continue to move with the movable mechanism 1, when the actuating mechanism 2 moves to the third station, the second clamping jaw 202 is made to face the direction of the recycling device 12 through the pivot driving the actuating mechanism 2 to rotate, and then the actuating mechanism 2 is controlled to move on the movable mechanism 1, so that the sample container 4 clamped by the second clamping jaw 202 is located above the recycling device 12, and the sample container 4 can be put into the recycling device 12 by releasing the second clamping jaw 202, completing the centralized recycling of the sample and the sample container 4.

[0097] Further, the driving device can be but is not limited to a driving motor, the output shaft of the driving motor is connected with one end of the rotating shaft, the rotating shaft is driven to rotate through the driving motor, and then the connecting plate 205 is driven to rotate by a certain angle.

[0098] In an optional embodiment of the utility model, the first clamp jaw 201 and the second clamp jaw 202 have the same structure. For example, the first clamp jaw 201 and the second clamp jaw 202 are openable and closable clamp jaws formed by two clamping heads capable of relatively moving, and a telescopic rod or other opening and closing structure capable of being electrically controlled is arranged between the two clamping heads. By connecting the telescopic rod or the opening and closing structure with the two clamping heads, the relative movement of the two clamping heads can be controlled, and the purpose of controlling the opening and closing action of the clamp jaw is achieved. Of course, other structures of the first clamp jaw 201 and the second clamp jaw 202 can also be used, and the structures of the first clamp jaw 201 and the second clamp jaw 202 can also be different, as long as the clamping and loosening actions of the sample container 3 to be measured and the sample container 4 that has been measured can be realized. The specific structure of the first clamp jaw 201 and the second clamp jaw 202 is not limited here.
