Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a sample processing module and a sample analysis system. Background Art

[0002] In the current production lines for automatic analysis, it is necessary to regularly use quality control products for quality control or use calibration products for calibration. Taking quality control products as an example, in order to avoid the failure or contamination of quality control products, quality control products need to be placed in sealed containers for storage. When quality control operations are required, the lid of the container needs to be opened first, and then the sample analyzer of the production line will aspirate the quality control product. In the related art, the lid of the container is usually opened by rotating around the vertical axis or moving in the vertical direction. However, there is another type of container on the market, whose lid needs to be opened by rotating around the horizontal axis. The automatic opening devices on the current production lines are difficult to apply to the opening of such containers, resulting in the need for manual opening of such containers, which affects the automation of the production line.

[0053] The first embodiment of the present invention provides a sample processing module for opening the cover of the sample container 300. Figure 1 、 Figure 2 The sample processing module includes a processing mechanism 200, an image acquisition mechanism 400, and a rotation mechanism. The rotation mechanism is used to drive the sample container 300 to rotate, the image acquisition mechanism 400 is used to acquire first image information of the sample container 300, and the processing mechanism 200 is used to perform an opening operation to drive the cap 322 from a closed position to an open position. In some embodiments, the sample processing module further includes a fixing mechanism 100, which is used to fix the sample container 300. The processing mechanism 200 is used to open the cap of the sample container 300 fixed by the fixing mechanism 100. In other embodiments, the processing mechanism 200 is also used to close the cap of the sample container 300.

[0054] For ease of description, first combine Figure 3 The sample container 300 applicable to the present invention is described as follows. Figure 3As shown, the sample container 300 includes a container body 310 and a container cap 320. The container body 310 has an inner cavity with an open end and a closed end, which is used to store samples. Specifically, the container body 310 has a cylindrical structure. When it is in a normal position, the opening is located at its top. The container cap 320 is a flip-top container cap, which specifically includes a cap body 321, a cap cover 322, and a connecting portion 323. The cap body 321 is connected to the end of the container body 310 with the opening. The cap cover 322 is connected to the cap body 321 via the connecting portion 323 and can move relative to the cap body 321 between an open position and a closed position. When the cap cover 322 is in the open position, the container cap 320 opens the opening, allowing components such as the sample analyzer's aspiration needle to be inserted into the container body 310 through the container cap 320. When the cap cover 322 is in the closed position, the container cap 320 closes the opening, sealing the inner cavity of the container body 310 and preventing sample leakage or contamination. In some specific embodiments, the connection portion 323 is configured as a rotating shaft. In other specific embodiments, the connection portion 323 is configured on a deformable structure, such as a connecting belt made of plastic.

[0055] It should be noted that, in some specific embodiments, one end (for example, the lower end) of the cap body 321 is connected to the upper end of the container body 310, and the other end (for example, the upper end) extends beyond the container body 310. The cap cover 322 is connected to the portion of the cap body 321 extending beyond the container body 310 through the connecting portion 323, and the portion extending beyond the cap body 321 also has an opening. The opening of the container body 310 is referred to as a first opening, and the opening of the portion extending beyond the cap cover 322 is referred to as a second opening. When the cap cover 322 is in a closed position, the cap cover 322 can close the second opening, so that the container cap 320 as a whole constitutes a closed cap, thereby closing the first opening of the container body 310 through the closed cap. When the cap cover 322 is in an open position, the cap cover 322 can open the second opening, and the first opening of the container body 310 is connected to the outside through the second opening. In other embodiments, although the cap 322 is connected to the cap body 321 through the connecting portion 323, when the cap 322 is in the closed position, the cap 322 can directly close the opening of the container body 310, that is, the aforementioned first opening, and when the cap 322 is in the open position, the cap 322 can directly open the first opening. For example, the cap body 321 is configured as an annular structure, which is sleeved on the outside of the container body 310 or inserted into the inside of the container body 310, and the upper end surface of the cap body 321 is flush with or slightly lower than the upper end surface of the container body 310. In this way, the cap 322 can directly close or open the first opening.

[0056] Compared to conventional container caps that are connected to the container body by threaded or plug-in connections and can be completely separated from the container body, the cap 322 of this embodiment is connected to the cap body 321 via the connection portion 323 and is opened and closed by a flipping method. Therefore, at least during the movement of the cap 322 from the closed position to the open position, the cap 322 is tilted relative to the horizontal plane. At the same time, even when the cap 322 is in the open position, it still remains connected to the container body 310 via the connection portion 323 and does not completely separate from the container body 310. In some specific embodiments, when the cap 322 is in the closed position, the cap 322 is in a horizontal or substantially horizontal state, and when the cap 322 is in the open position, the cap 322 is in a vertical or substantially vertical state.

[0057] Next, the fixing mechanism 100, the processing mechanism 200, the rotating mechanism and the image acquisition mechanism are briefly described. The fixing mechanism 100 is used to fix the sample container 300. In some embodiments, the sample container is placed on a sample carrying component, which can be a sample rack or a single tube holder. Taking the latter as an example, when the sample processing module is applied to the sample analysis system, the sample container 300 is placed on the single tube holder, which is transferred through the sample transmission module of the sample analysis system. When the single tube holder carrying the sample container 300 is transferred to the sample processing module, the fixing mechanism 100 fixes the sample container 300 on the single tube holder. After the processing mechanism 200 completes the opening operation, the fixing mechanism 100 is released, and the sample transmission module can then further transport the single tube holder carrying the opened sample container 300 to the sample analysis module for analysis. It should be noted that in order to achieve the sealing function, the connection force between the cap 322 and the cap body 321 or the container body 310 is relatively large when the cap 322 is in the closed position. Therefore, a large force needs to be applied to the cap 322 to achieve opening. By fixing the sample container 300 through the fixing mechanism 100, displacement of the sample container 300 can be avoided during the opening process.

[0058] The processing mechanism 200 specifically includes a toggle component 210, which can be driven by a corresponding driving component. Based on this, the processing mechanism 200 performs the opening operation specifically means: when the cap 322 is in the closed position, the toggle component 210 performs the opening action to drive the cap 322 to move from the closed position to the open position.

[0059] The rotating mechanism is used to drive the sample container 300 to rotate. Specifically, the rotating mechanism includes a rotating component and a driving component. The driving component is used to drive the rotating component to rotate to drive the sample container 300 to rotate. The rotating mechanism can directly drive the sample container 300 to rotate, or it can indirectly drive the sample container 300 to rotate. For the former, the rotating component directly acts on the sample container and can drive the sample container 300 to rotate. For example, the rotating component is a roller, and the roller can abut against the sample container 300 from the side, thereby driving the sample container 300 to rotate through friction. For the latter, when the sample container 300 is placed on the sample carrying component, the rotating component directly acts on the sample carrying component and can drive the sample carrying component and the sample container 300 thereon to rotate synchronously. For example, the rotating component is a turntable, and the sample carrying component can be transferred to the turntable, and then the state drives the sample carrying component to rotate. For another example, the rotating component is the aforementioned roller, and the roller can abut against the sample carrying component from the side, thereby driving the sample container carrying component and the sample container 300 thereon to rotate through friction.

[0060] The image acquisition mechanism is used to acquire image information of the sample container. The image acquisition mechanism may include a camera that can capture images from the side or top of the sample container to acquire image information. In some embodiments, the image acquisition mechanism can acquire image information before, during, and after the rotation mechanism drives the sample container to rotate. The controller can perform corresponding control based on this image information, which will be explained in subsequent embodiments.

[0061] In this embodiment, the controller is configured to control the image acquisition mechanism 400 to acquire first image information, control the rotation mechanism to drive the sample container 300 to rotate to the first set position based on the first image information, and control the toggle component 210 to perform an opening action on the sample container 300 rotated to the first set position. As mentioned above, the cap 322 of the sample container 300 applicable to the present invention is opened or closed in a flipping manner, so it has a fixed opening position, such as a flange 3222 located on one side of the cap 322. In order to reduce the difficulty of controlling the toggle component 210 and simplify the toggle, The structure of the driving component of the toggle component 210, the toggle component 210 is usually fixed to perform the opening action from one side, so the opening part of the sample container 300 is required to be aligned with the toggle component 210. However, when the sample container 300 is transferred to the sample processing module, its opening part may have various orientations. Therefore, the controller in this embodiment obtains first image information through the image acquisition mechanism, and controls the rotation of the rotating mechanism based on the first image information, so that the sample container 300 can be accurately rotated to the first set position suitable for opening the cover, which is suitable for this type of flip-top sample container 300.

[0062] It should be noted that the image acquisition mechanism 400 can acquire the first image information during the rotation of the sample container 300. For example, the rotation mechanism first drives the sample container 300 to rotate, and then the image acquisition mechanism 400 acquires the first image information. Then, the controller controls the rotation mechanism to continue to drive the sample container 300 to rotate to the first set position based on the first image information. The image acquisition mechanism 400 can also acquire the first image information before and during the rotation of the sample container 300. For example, the image acquisition mechanism 400 first acquires the first image information, and the controller controls the rotation mechanism to drive the sample container 300 to rotate based on the first image information acquired at this time. The image acquisition mechanism 400 will also continue to acquire the first image information during the rotation process, and the controller controls the rotation mechanism to continue to drive the sample container 300 to rotate to the first set position based on the first image information acquired at this time.

[0063] On the basis of the first embodiment, in some embodiments of the present invention, the image acquisition mechanism 400 acquires the first image information at least during the rotation of the sample container 300. Based on this, the aforementioned "controlling the image acquisition mechanism 400 to acquire the first image information, and controlling the rotating mechanism to drive the sample container 300 to rotate to the first set position based on the first image information acquired by the image acquisition mechanism 400" specifically refers to: controlling the image acquisition mechanism 400 to acquire multiple first image information of the sample container 300, and controlling the rotating mechanism to drive the sample container 300 to rotate continuously based on the multiple first image information until the sample container 300 rotates to the first set position and stops driving.

[0064] As a specific implementation method for the image acquisition mechanism 400 to acquire multiple first image information of the sample container 300, the image acquisition mechanism 400 can continuously photograph the sample container 300 at equal or different intervals to obtain multiple first image information. The controller corrects the rotation angle of the sample container 300 based on the multiple first image information. For example, at a specific moment, the controller determines whether the sample container 300 has reached the first set position based on the latest first image information at that moment. If so, the controller controls the rotation mechanism to stop; if not, the controller controls the rotation mechanism to continue driving.

[0065] In this embodiment, since the rotating mechanism drives the sample container 300 to rotate non-stop, the sample container 300 can reach the first set position quickly, which helps to improve efficiency.

[0066] Based on the first embodiment, in some embodiments of the present invention, the image acquisition mechanism 400 acquires first image information at least during the rotation of the sample container 300. Therefore, the aforementioned "controlling the image acquisition mechanism 400 to acquire first image information, and controlling the rotation mechanism to drive the sample container 300 to rotate to the first set position based on the first image information acquired by the image acquisition mechanism 400" specifically refers to: controlling the image acquisition mechanism 400 to acquire multiple first image information of the sample container 300, and controlling the rotation mechanism to drive the sample container 300 to rotate based on the multiple first image information, at intervals between acquisitions of the first image information by the image acquisition mechanism 400, until the sample container 300 reaches the first set position and stops driving. That is, the difference between this embodiment and the aforementioned embodiment is that, whereas in the aforementioned embodiment, the rotation mechanism drives the sample container 300 to rotate continuously to the first set position, in this embodiment, the rotation mechanism drives the sample container 300 to rotate intermittently.

[0067] Similarly, as a specific implementation method for the image acquisition mechanism 400 to acquire multiple first image information of the sample container 300, the image acquisition mechanism 400 can continuously photograph the sample container 300 at the same interval or at different intervals, thereby acquiring multiple first image information. The controller corrects the rotation angle of the sample container 300 based on the multiple first image information, specifically controlling the next rotation angle based on the first image information acquired during the previous acquisition operation. For example, at a certain moment, the rotation mechanism is in a stopped driving state. After the controller acquires the next single rotation angle based on the previously acquired first image information, the rotation mechanism drives the sample container 300 to rotate again. After the sample container 300 rotates the single rotation angle, the rotation mechanism stops again and waits for the controller to acquire the next single rotation angle based on the second image information acquired again. The rotation mechanism then drives the sample container 300 to rotate again, and this cycle continues until the sample container 300 is in the first set position.

[0068] Typically, due to the influence of processing speed, the calculation process for the controller to obtain the rotation angle of the sample container 300 based on the first image information takes a certain amount of time. When the rotation speed of the sample container 300 is relatively fast, if the sample container 300 rotates continuously, there may be a problem of lag in the control instructions of the controller. The rotation mechanism of this embodiment waits for the controller to calculate the rotation angle before driving, which can avoid the lag problem and improve the position accuracy of the sample container 300.

[0069] As mentioned above, if the rotating mechanism drives the sample container 300 to rotate to the first set position non-stop, it takes less time and is highly efficient, but it may cause inaccuracy due to signal lag. If the rotating mechanism drives the sample container 300 to rotate to the first set position intermittently, the position accuracy is high, but there are problems of being time-consuming and inefficient. Based on this, some embodiments of the present invention use a rotating mechanism to first drive the sample container 300 to rotate to the second set position non-stop, and then intermittently rotate it to the first set position. On the basis of ensuring position accuracy, it can reduce time and improve efficiency.

[0070] Specifically, the aforementioned “controlling the image acquisition mechanism 400 to acquire first image information, and controlling the rotating mechanism to drive the sample container 300 to rotate to the first set position based on the first image information acquired by the image acquisition mechanism 400” specifically refers to: controlling the image acquisition mechanism 400 to acquire multiple first image information of the sample container 300, and controlling the rotating mechanism to continuously drive the sample container 300 to rotate to the second set position based on the multiple first image information, and controlling the rotating mechanism to intermittently drive the sample container 300 to rotate from the second set position to the first set position, wherein, in the process of the sample container 300 rotating from the second set position to the first set position, the rotating mechanism drives the sample container 300 to rotate during the intervals when the image acquisition mechanism 400 acquires the first image information. That is, this embodiment divides the action of rotating the sample container 300 from the current position to the first set position into two sections. The first section is rotating from the current position to the second set position between the current position and the first set position, and the second section is rotating from the second set position to the first set position. In the first section, the rotating mechanism drives the sample container 300 to rotate continuously. Since there is a certain angle between the second set position and the first set position, even if the sample container 300 cannot accurately stop at the second set position due to signal lag, it will not affect the final position accuracy; in the second section, the rotating mechanism drives the sample container 300 to rotate intermittently, so that the sample container 300 can accurately stop at the first set position. Since intermittent rotation only needs to be performed in the second section, the total time will be shortened accordingly compared to the solution of intermittent rotation throughout the entire process.

[0071] It should be noted that in order to shorten the time consumed for rotation, the second set position should be as close to the first set position as possible. For example, the angle between the second set position and the first set position can be determined by parameters such as the rotation speed of the sample container 300 and the calculation time of the controller to obtain the rotation angle based on the first image information.

[0072] On the basis of the first embodiment, in some embodiments of the present invention, the aforementioned “controlling the rotating mechanism to drive the sample container 300 to rotate to the first set position based on the first image information” specifically refers to: obtaining the angular difference between the actual position of the sample container 300 and the first set position based on the first image information, and controlling the rotating mechanism to drive the sample container 300 to rotate to the first set position based on the angular difference.

[0073] It should be noted that in some specific embodiments, the image acquisition mechanism 400 acquires multiple first image information during the rotation of the sample container 300. The controller obtains the corresponding angle value based on each first image information, and controls the rotation mechanism to drive the sample container 300 to rotate based on the latest obtained angle value. Since multiple judgments are performed during the rotation process, the position accuracy of the sample container can be improved.

[0074] When obtaining the angular difference between the actual position of the sample container 300 and the first set position based on the first image information, in some embodiments of the present invention, the first image information is first input into a neural network model, which then identifies a feature on the sample container 300. The controller's angle recognition algorithm module then determines the angular difference based on information such as the feature's size, angle, and distance from a reference point. For example, the neural network model can also identify a reference point on the sample container 300. The angle recognition algorithm module calculates the distance between the feature and the reference point, then substitutes this distance into a distance-angle fitting curve to determine the angular difference. The feature may be a protrusion on the container cap 320, and the reference point may be the center of the container cap 320.

[0075] It should be noted that when the image acquisition mechanism 400 takes the first picture of the sample container 300, the first image information obtained may not display features, or the features cannot be clearly identified. At this time, the controller first controls the rotation mechanism to drive the sample container 300 to rotate, and the image acquisition mechanism 400 continues to acquire the first image information during the rotation process. When features appear in the first image information, or the features can be clearly identified, the controller obtains the angle difference based on the first image information.

[0076] On the basis of the first embodiment, in some embodiments of the present invention, the sample processing module further includes a processing position, the image acquisition mechanism 400 is configured to acquire first image information of the sample container 300 located at the processing position, the rotation mechanism is configured to drive the sample container 300 located at the processing position to rotate, and the processing mechanism 200 is configured to perform an opening action on the sample container 300 located at the processing position and rotated to the first set position. In some embodiments, the fixing mechanism 100 is configured to fix the sample container located at the processing position, that is, the image acquisition mechanism 400, the rotation mechanism, the processing mechanism 200 and the fixing mechanism 100 can perform image acquisition, rotation, opening and fixing on the sample container 300 at the same position. For example, the image acquisition mechanism 400 and the processing mechanism 200 are both located on the side of the processing position, and the fixing mechanism 100 is located at the top of the processing position. When the rotation mechanism includes the aforementioned turntable, the rotation mechanism is located at the bottom of the processing position. When the rotation mechanism includes the aforementioned roller, the rotation mechanism is also located on the side of the processing position.

[0077] On the basis of the first embodiment, in some embodiments of the present invention, the controller is further configured to control the image acquisition mechanism 400 to acquire second image information of the sample container 300 after the sample container 300 rotates to the first set position, control the toggle component 210 to move to the cover-opening position based on the second image information, and control the toggle component 210 moved to the cover-opening position to perform the cover-opening action on the sample container 300 rotated to the first set position.

[0078] For the flip-top sample container 300, the cap 322 is usually provided with an opening portion, for example, Figure 3 The cap 322 includes a cover body 3221 and a flange 3222. The flange 3222 is used as an opening portion for contacting the toggle member 210. In addition, different types of sample containers 300 have different heights, and the heights of the corresponding container caps 320 are also different. Based on the above factors, the image acquisition mechanism 400 of this embodiment can obtain the second image information of the sample container 300. Based on the second image information, the controller can control the toggle member 210 to move to the opening position, so that the toggle member 210 can accurately contact the opening portion on the cap 322, thereby achieving normal opening. Figure 3 As shown in the example, when the toggle member 210 is in the cover-opening position, the toggle member 210 is located below the flange 3222 and abuts against the flange 3222 .

[0079] It should be noted that, for sample containers 300 of different heights, the corresponding opening positions of the shifting component 210 are different.

[0080] When the image acquisition mechanism 400 is also capable of acquiring second image information of the sample container 300 after the sample container 300 is rotated to the first set position, in some embodiments of the present invention, the aforementioned "controlling the movement of the toggle member 210 to the lid-opening position based on the second image information" specifically refers to acquiring the height of the cap 322 based on the second image information, and controlling the movement of the toggle member 210 to the lid-opening position based on the height. It should be noted that acquiring the height of the cap 322 herein should be understood as acquiring the height of the lid-opening portion of the cap 322 that contacts the actuator 210, such as the height of the aforementioned flange 3222. It should also be noted that the method for acquiring the height of the cap 322 based on the second image information can be understood similarly to the method for acquiring the angle difference based on the first image information. For example, a neural network model may be used to identify a feature of the cap 322 in the second image information, such as the flange, and then the height recognition algorithm module may determine the height based on the distance between the feature and a reference point.

[0081] It should be noted that the range of the opening portion of the cap 322 is relatively small. In order to enable the toggle component 210 to accurately contact the opening portion of the cap 322 and avoid the toggle component 210 contacting other portions of the cap 322, the toggle component 210 needs to have a high positioning accuracy. In this embodiment, the actual height of the sample container 300 is identified by the second image information, and the sample container 300 is placed in the first set position by the first image information, thereby ensuring that the toggle component 210 can contact the opening portion of the cap 322.

[0082] On the basis of the first embodiment, in some embodiments of the present invention, the controller is further configured to control the image acquisition mechanism 400 to acquire third image information containing images of the sample container 300 and the toggle component 210 during the process of the toggle component 210 performing the cover opening action, and control the movement trajectory of the toggle component 210 during the process of performing the cover opening action based on the third image information.

[0083] Since the sample container 300 of the present invention is a flip-top sample container, the cap 322 and the cap body 321 are usually connected by an elastic connector. Therefore, in some scenarios, the cap 322 may bounce upward under the action of the elastic connector after leaving the closed position, causing the toggle component 210 to detach from the cap 322. The controller of this embodiment can control the movement trajectory of the toggle component 210 during the opening action based on the third image information, so that the driving component 210 can maintain contact with the cap 322, and thus the toggle component 210 can continue to open the cap 322. For example, when the controller obtains that the driving component 210 has detached from the cap 322 based on the third image information, it can drive the toggle component 210 to move along other trajectories until it contacts the cap 322, and then continue to move along the original opening trajectory to open the cap.

[0084] In addition, in other scenarios, some areas of the cap 322 will directly contact the sample. In order to prevent the toggle component 210 from contaminating the sample or being contaminated by the sample, the toggle component 210 should be prevented from contacting specific areas of the cap 322. The controller of this embodiment can control the movement trajectory of the toggle component 210 during the opening action based on the third image information, so that the toggle component 210 maintains contact with the opening part of the cap 322, and will not deviate to the specific area where the cap 322 can contact the sample.

[0085] In some specific embodiments, referring to Figure 3 The cap 322 includes a cover body 3221 and a flange 3222 for abutting against the toggle member 210. Specifically, the cover body 3221 is connected to the cap body 321 via a connecting portion 323. When the upper end of the cap body 321 exceeds the container body 310, the cover body 3221 can open or close the second opening of the cap body 321. When the upper end surface of the cap body 321 is flush with or slightly lower than the upper end surface of the container body 310, the cover body 3221 can open or close the first opening of the container body 310. In other words, the cover body 3221 is the portion of the cap 322 that can contact the sample.

[0086] The cover body 3221 has a first side and a second side that are arranged opposite to each other, the connecting portion 323 is connected to the first side of the cover body 3221, and the flange 3222 is connected to the second side of the cover body 3221. It should be noted that the first side and the second side referred to here are used to express a rough positional relationship, and are distinguished by a vertical plane passing through the central axis of the cover body 3221. The connecting portion 323 is located within the range of one side of the vertical plane, and the flange 3222 is located within the range of the other side of the vertical plane. In some specific embodiments, the connecting portion 323 and the flange 3222 are completely opposite to each other (such as Figure 3 As shown), in other embodiments, the flange 3222 deviates from the connecting portion 323.

[0087] Based on this, the aforementioned "controlling the movement trajectory of the toggle component 210 during the cover opening action based on the third image information" specifically refers to: controlling the toggle component 210 to maintain contact with the flange 3222 during the cover opening action based on the third image information. In this way, the toggle component 210 can be prevented from contacting the cover body 3221, and the toggle component 210 can be prevented from contaminating the sample in the sample container, or being contaminated by the sample in the sample container. At the same time, it is also convenient to apply force to the cap 322 to open the cap 322.

[0088] Based on the first embodiment, in some embodiments of the present invention, the controller is further configured to control the image acquisition mechanism 400 to acquire fourth image information of the sample container 300 after the toggle member 210 performs the cap opening action, and determine whether the cap 322 is successfully opened based on the fourth image information. If the cap 322 is not successfully opened, the toggle member 210 is controlled to perform the cap opening action again. Determining whether the cap 322 is successfully opened based on the fourth image information may include comparing the actual posture of the cap 322 in the fourth image information with a preset opening posture. If the two are the same, it is determined that the cap 322 has been opened; if the two are different, it is determined that the cap 322 has not been successfully opened. Determining whether the cap 322 is successfully opened based on the fourth image information may also include identifying features of the cap 322 in the fourth image information using a neural network model, and further determining the distance or height between the feature and a reference point. If the distance or height meets a set value, it is determined that the cap 322 has been opened; if the distance or height does not meet the set value, it is determined that the cap 322 has not been successfully opened.

[0089] It should be noted that, in some specific embodiments, before the toggle member 210 performs the lid opening action again, the controller is further configured to control the image acquisition mechanism 400 to acquire sixth image information of the sample container 300, and based on the sixth image information, to obtain the actual position of the cap 322. Based on the actual position, the toggle member 210 is controlled to move until it abuts the cap 322, and finally the toggle member 210 is controlled to perform the lid opening action again. In other specific embodiments, the toggle member 210 may also perform the lid opening action again directly from the initial lid opening position.

[0090] On the basis of the first embodiment, in some embodiments of the present invention, referring to Figure 3 The cap 322 includes a cover body 3221 and a flange 3222 for contacting the toggle member 210. The cover body 3221 and the flange 3222 can be understood with reference to the aforementioned embodiment. When the sample container 300 is rotated to the first set position, the flange 3222 faces the toggle member 210. As previously mentioned, the cap 322 of the present invention is opened or closed by flipping, and therefore has a fixed opening portion, such as the flange 3222 in this embodiment. By setting the flange 3222 to face the toggle member 210 when the sample container 300 is rotated to the first set position, this embodiment allows the toggle member 210 to perform the opening action from a fixed side, thereby reducing control difficulty and simplifying the structure.

[0091] In some specific embodiments, when the cap 322 includes a cover body 3221 and a flange 3222 for abutting against the toggle member 210, in some embodiments of the present invention, referring to Figure 5The toggle member 210 includes a lid opening portion 211, which is used to abut against the flange 3222 during the lid opening process. The lid opening portion 211 has an escape space 2111, wherein the escape space 2111 is configured to avoid the lid body 3221 when the lid opening portion 211 abuts against the flange 3222. In this way, the toggle member 210 can be ensured to abut against the flange 3222 while preventing the toggle member 210 from contacting the lid body 3221. In some specific embodiments, the escape space 2111 is adapted to the shape of the container body 310. For example, the inner wall of the escape space 2111 facing the container body 310 is configured as a curved surface.

[0092] On the basis of the first embodiment, in some embodiments of the present invention, the opening action of the toggle component 210 includes at least vertical movement, and the vertical movement is used to at least partially separate the cap 322 from the cap body 321 to move the cap away from the closed position. It should be noted that the separation of the cap 322 from the cap body 321 means that the two have no direct contact, but it does not mean that there is no connection between the two. As mentioned above, even if the cap 322 is completely separated from the cap body 321, the two will still remain connected through the connecting portion 323.

[0093] It should also be noted that the closed position referred to in this embodiment refers to the position where the cap 322 is in which the container cap 320 can close the opening of the container body 310, and more specifically refers to the horizontal position shown in the figure. In other words, as long as the cap 322 moves so that the container cap 320 can no longer close the opening of the container body 310, it means that the cap 322 has left the closed position.

[0094] It should also be noted that, the cover opening action at least includes vertical movement, which refers to the situation that the cover opening action only includes vertical movement, and also refers to the situation that the cover opening action includes both vertical movement components and movement components in other directions. For the former, for example, the toggle component 210 moves vertically upward from the bottom of the cap 322, so that one end of the cap 322 is tilted and leaves the closed position, and there will be relative movement between the toggle component 210 and the cap 322 during the subsequent flipping process. For the latter, for example, the toggle component 210 moves from the bottom of the cap 322 along an oblique trajectory or an arc trajectory, so that one end of the cap 322 is tilted and leaves the closed position, and there will be no relative movement between the toggle component 210 and the cap 322 during the flipping process, or there will be only a small movement. In this way, the toggle component 210 will not contact a specific area of ​​the cap 322.

[0095] In some further embodiments, referring to Figure 4The opening action of the toggle component 210 includes simultaneous horizontal and vertical movements. For example, the toggle component 210 moves along an oblique trajectory or an arc trajectory. The simultaneous horizontal and vertical movements are used to completely separate the cap 322 from the cap body 321 so that the cap moves to the open position. It should be noted that even if the opening action only includes vertical movement, the cap 322 can be driven to completely separate from the cap body 321 so that the cap moves to the open position.

[0096] On the basis of the first embodiment, in some embodiments of the present invention, referring to Figure 6 The processing mechanism 200 further includes a first drive assembly 220 and a second drive assembly 230. The first drive assembly 220 is configured to drive the toggle member 210 and the second drive assembly 230 to move horizontally, and the second drive assembly 230 is configured to drive the toggle member 210 to move vertically. The first drive assembly 220 and the second drive assembly 230 can be a transmission assembly based on a motor-synchronous belt, a drive assembly based on a motor-screw, etc. Figure 6 As shown in the example, the first drive assembly 220 includes a first power component 221, a first transmission belt 222, a first transmission wheel 223, a first mounting seat 224 and a first slide rail 225, wherein the drive shaft of the first power component 221 is connected to the first transmission wheel 223, the first transmission belt 222 is wound around the first transmission wheel 223, and can be driven by the first power component 221 to rotate in a circle, the first mounting seat 224 is fixedly connected to the first transmission belt 222, and is slidingly connected to the first slide rail 225, the first slide rail 225 is arranged in the horizontal direction, and the toggle component 210 is connected to the first mounting seat 224, so that as the first power component 221 is driven, the toggle component 210 can move in the horizontal direction. Similarly, the second drive assembly 230 includes a second power component 231, a second transmission belt 232, a second transmission wheel 233, a second mounting seat 234 and a second slide rail not shown, wherein the drive shaft of the second power component 231 is connected to the second transmission wheel 233, the second transmission belt 232 is wound around the second transmission wheel 233, and can be driven by the second power component 231 to rotate in a circle, the second mounting seat 234 is fixedly connected to the second transmission belt 232, and is slidingly connected to the second slide rail, and the second slide rail is arranged in the horizontal direction, and the first power component 221 of the first drive assembly 220 and the first transmission wheel 223 are fixedly connected to the second mounting seat 234, so that as the second power component 231 is driven, the toggle component 210 and the first drive assembly 220 can move in the vertical direction.

[0097] On the basis of the first embodiment, in some embodiments of the present invention, referring to Figure 7The fixing mechanism 100 includes a third drive assembly 110, at least two clamping components 120, and at least two correcting components 130. Each clamping component 120 is connected to the third drive assembly 110 and can be driven by the third drive assembly 110 to perform a clamping operation on the sample container 300. Each correcting component 130 is connected to the third drive assembly 110 and can be driven by the third drive assembly 110 to perform a correcting operation on the sample container 300. After the correcting operation, the angle between the central axis of the container body 310 and the horizontal plane is greater than the angle between the central axis of the container body 310 and the horizontal plane before the correcting operation. For example, when the sample container 300 is not properly placed, the central axis of the sample container 300 has a larger angle with the horizontal plane, thereby being in a tilted state. After the correcting operation, the sample container 300 is in a vertical or substantially vertical state, thereby facilitating clamping by the clamping components 120.

[0098] In this embodiment, for the sample container 300 in a tilted state, the third driving component 110 first corrects the sample container 300. When the sample container 300 is corrected to a vertical or approximately vertical state, the clamping component 120 clamps the sample container 300. It should be noted that the clamping of the sample container referred to here means that the container body 310 and the cap body 321 of the sample container 300 will not be displaced by the opening action of the toggle component 210. It should also be noted that the correction action of the correction component 130 and the clamping action of the clamping component 120 can be performed sequentially or simultaneously. For example, the correction component 130 performs the correction action first, and when the sample container 300 is corrected to the correct posture, the clamping component 120 then performs the clamping action and finally clamps the sample container 300. For another example, while the correction component 130 is correcting the sample container 300, the clamping component 120 begins to perform the clamping action, and during the first period of time of the clamping action, the clamping component 120 does not contact the sample container 300. During the second period of time of the clamping action, the clamping component 120 contacts the sample container 300 and further clamps it. It should also be noted that the third drive assembly 110 can drive the clamping component 120 and the correction component 130 to move using a single power component, or can drive the clamping component 120 and the correction component 130 to move using different power components.

[0099] In some specific embodiments, referring to Figure 7 The correcting component 130 includes two correcting portions 131, and the two correcting portions 131 form a gap with gradually increasing width. In this way, when the tilted sample container 300 is located between the two correcting components 130, as the correcting components 130 move toward each other, the sample container 300 will be guided by the correcting components 130 to be in a vertical or approximately vertical state.

[0100] The second embodiment of the present invention provides a sample analysis system, which includes a sample analysis module, a sample transfer module, and the sample processing module of the aforementioned embodiments. In some embodiments, the sample analysis system further includes a sample management module or a cryogenic storage module, wherein the sample management module is used to place sample containers carrying samples, wherein the samples in the sample containers can be samples to be processed or samples to be recovered. The cryogenic storage module is used to store samples at low temperatures, and the samples stored therein include both analyzed case samples and quality control samples, calibration samples, and samples that require short-term storage. The sample transfer module is used to transfer sample containers. In some embodiments, the sample transfer module is a track module, which specifically includes a main track and multiple front rails connected to the main track. The front rails connect modules such as the sample analysis module, the sample management module, and the cryogenic storage module. The sample analysis module is used to test samples. Specifically, the analysis module's aspiration function aspirates the samples in the sample containers on the sample transfer module track, and then performs analysis operations. It should be noted that the samples analyzed by the sample analysis module include both unanalyzed common cases from the sample management module, common cases that need to be retested from the low-temperature storage module, and quality control samples or calibration samples from the sample management module or the low-temperature storage module.

[0101] In this embodiment, the sample transmission module is also used to connect the sample processing module. Depending on the source of the sample to be processed, the sample transmission module can be set between the sample management module and the sample analysis module, or between the low-temperature storage module and the sample analysis module. When the toggle component 210 performs the opening action to make the cap 322 of the sample container 300 in the open position, the sample transmission module is used to transport the sample container 300 to the sample analysis module to facilitate analysis by the sample analysis module.

[0102] Based on the second embodiment, sample containers 300 that have been analyzed by the sample analysis module need to be capped before being transferred to the cryogenic storage module for storage. Based on this, in other embodiments, the toggle member 210 can also be used to cap the opened sample container. Specifically, the controller is further configured to control the image acquisition mechanism 400 to acquire fifth image information of the analyzed sample container 300, control the rotation mechanism to rotate the sample container 300 to a third set position based on the fifth image information, and control the toggle member 210 to cap the sample container 300 rotated to the third set position, thereby driving the cap 322 from the open position to the closed position. In some specific embodiments, the cap-closing action includes at least vertical movement, for example, the toggle member 210 moves vertically downward when performing the cap-closing action, or the toggle member 210 moves both downward and horizontally when performing the cap-closing action. In some specific embodiments, the cap-closing action includes at least horizontal movement, for example, the toggle member 210 moves horizontally when performing the cap-closing action, thereby pushing the cap 322 closed. In some specific embodiments, the closing action includes a combination of multiple actions. For example, the toggle member 210 first moves horizontally to tilt the vertical cap 322, and then the toggle member 210 moves downward to move the tilted cap 322 to a horizontal state.

[0103] In this embodiment, the image acquisition mechanism 400 acquires fifth image information, and the controller controls the rotation mechanism to drive the sample container 300 to rotate based on the fifth image information, so that the sample container 300 can be accurately stopped at the third set position.

[0104] It should be noted that, in some specific embodiments, when the sample container 300 is in the third setting position, the connecting portion 323 is located on the side of the cap 322 facing the shifting component 210 .

[0105] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
