Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a detection equipment and a method for automatically conveying a sample container. Background Art

[0002] In the medical field, breath tests are used to diagnose certain diseases. They are quick, safe, and painless, contributing to early diagnosis and treatment. Typically, a sample container is used to collect the subject's exhaled air, which is then tested by a test device. The gas content of the labeled element is measured to determine the appropriate diagnosis.

[0003] Current testing equipment typically features a platform that can enter and exit the housing and darkroom to load sample containers for testing. During operation, the platform is extended from the device housing, and the sample container is manually placed on the platform. The platform then drives the sample container into the darkroom for testing. After testing is complete, the platform transports the sample container from the darkroom to the exterior of the housing, where it is manually retrieved. This requires manual assistance, and when a large number of sample containers are involved, testing efficiency is low. Summary of the Invention

[0054] Figure 1 is a schematic structural diagram of a detection device according to an embodiment of the present invention, Figure 2 for Figure 1 Partial structural diagram of the detection equipment in Figure 1 and Figure 2A first embodiment of the present invention provides a detection device, including a chassis 100, a detection device 200, a sample delivery device 300, a sample injection device 400 and a controller (not shown). The chassis 100 has an installation cavity 102 inside, and the detection device 200 is arranged in the installation cavity 102. The chassis 100 is provided with an injection port 101 for the sample container 500 to enter and exit the installation cavity 102. The sample delivery device 300 is arranged outside the installation cavity 102 corresponding to the side of the injection port 101. The injection device 400 is connected to the chassis 100. The sample delivery device 300 is used to transfer the sample container 500 to the injection device 400. The injection device 400 is used to inject the sample container 500 at the sample delivery device 300 into the detection device 200 in the installation cavity 102. The detection device 200 is used to detect the sample in the sample container 500. The injection device 400 can also take the sample container 500 at the detection device 200 out of the sample to the sample delivery device 300, thereby realizing the transmission of the sample container 500. The controller is used to control the actions of the above-mentioned devices. Among them:

[0055] The detection device 200 includes a detector 210, a detection sensing module and a detection chamber 220. The detector 210 is used to detect the sample located in the detection chamber 220. The detection sensing module is configured to sense whether the sample container 500 is located at a set position in the detection chamber 220 and issue a detection indication signal.

[0056] The sample delivery device 300 includes a sample platform 310, a sample rack sensing module, and a sample rack driving module. The sample platform 310 is used to support a sample rack 340, which in turn supports a sample container 500. The sample rack driving module is used to drive the sample rack 340 to move on the sample platform 310, thereby enabling the sample rack 340 to move to a position corresponding to the sample injection device 400, allowing the sample injection device 400 to retrieve the sample container 500 or return the sample container 500 to the sample rack 340. The sample rack sensing module is configured to sense the position of the sample rack 340 on the sample platform 310 and issue a sample rack position indication signal.

[0057] The sampling device 400 includes a sampling mechanism 401, a sampling sensing module, a moving mechanism 440 and a moving sensing module. The sampling mechanism 401 is used to take and place the sample container 500 and can enter and exit the chassis 100 from the sampling port 101. The sampling sensing module is configured to sense whether there is a sample container 500 on the sampling mechanism 401 and issue a sampling indication signal. The moving mechanism 440 is used to drive the sampling mechanism 401 to move between the sample platform 310 and the detection chamber 220. The sampling mechanism 401 can perform sampling or placing actions on the sample rack 340 set at a position on the sample platform 310. The moving sensing module is configured to sense the position of the sampling mechanism 401 and issue a position indication signal of the sampling mechanism 401.

[0058] The controller is respectively connected to the detection device 200, the sample delivery device 300, and the sample injection device 400, receives the instruction signal and calculates and generates the corresponding control signal according to the set program and sends it to each module, thereby controlling the operation of each device and realizing the transmission control of the sample container 500. The controller is a feedback loop component widely used in industrial control applications. It stores instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations, and can calculate and generate corresponding control signals according to the set program. The specific process and operation method of the controller to implement the operation control can be easily implemented by those skilled in the art and will not be described in detail here. Accordingly, the controller of the embodiment of the present invention can calculate the signals input by each sensing module and generate corresponding control signal outputs to control the operation of each device.

[0059] As can be seen from the above, in the detection device of the embodiment of the present invention, the sample delivery device 300 carries the sample container 500 via the sample rack 340, and can move and position the sample rack 340 to achieve automatic sample delivery of the sample container 500. The sample introduction device 400 uses the sampling mechanism 401 to perform the sample container 500 placement operation between the sample rack 340 and the detection chamber 220, and moves the sampling mechanism 401 between the sample rack 340 and the detection chamber 220 via the moving mechanism 440 to achieve the movement of the sample container 500. The sample introduction device 400 can also sense the position of the sampling mechanism 401 to determine the position of the sample container 500, thereby achieving automatic sample introduction and removal of the sample container 500. The detection device 200 uses the above-mentioned detector 210 and detection sensing module to automatically detect the sample container 500 delivered by the sample introduction device 400 to the detection chamber 220. The controller can calculate and generate corresponding control signals according to the set program and send them to the detection device 200, the sample delivery device 300, and the sample injection device 400 to realize the action control of each device, thereby realizing automatic transmission and automatic detection of the sample container 500. This process does not require manual assistance, thereby improving detection efficiency.

[0060] In the detection device of the above embodiment, the detection sensing module, the sample rack sensing module, the sampling sensing module and the movement sensing module may respectively include one or more sensors to achieve signal transmission.

[0061] In some embodiments, the detection apparatus includes a detection device 200, wherein a moving mechanism 440 can drive a sampling mechanism 401 to move between a sample rack 340 and a detection chamber 220 of the detection device 200, thereby transferring a sample container 500 between the sample rack 340 and the detection chamber 220. During detection, a controller receives a detection indication signal from a detection sensing module and issues a control signal to control the start and stop of the detector 210 and / or the corresponding operation of the sample injection device 400. For example, when the detection sensing module senses that the sample container 500 is located in the detection chamber 220, the detection sensing module issues a positive indication signal instructing the detector 210 to perform detection; otherwise, it issues a negative indication signal. The controller controls the detector 210 to perform detection only when receiving the positive indication signal. When receiving the negative indication signal, the controller can instruct the detector 210 in the detection state to stop detection or instruct the detector 210 in the stopped state to remain stopped. Furthermore, the controller can instruct the sample injection device 400 to inject sample into the detection chamber 220.

[0062] In some embodiments, the detection device includes multiple independent detection devices 200. The moving mechanism 440 can drive the sampling mechanism 401 to move between the sample rack 340 and the detection chamber 220 of each detection device 200, thereby enabling sample injection or sample removal operations to be performed on each detection chamber 220. Therefore, the detection device of this embodiment can simultaneously and independently test samples in multiple sample containers 500, further improving detection efficiency compared to a detection device with only a single detection device 200. Specifically, in a detection device with only a single detection device 200, the sample delivery device 300 and the sample injection device 400 can achieve automatic transfer of the sample container 500, which can improve detection efficiency to a certain extent compared to conventional detection devices. However, during the transfer of the sample container 500, the detection device 200 is idle. After each test is completed, it is necessary to wait for a complete sample removal, placement, sampling, and injection operation before the next test can be performed. Since sample testing requires a certain amount of time, the sample injection device 400 is idle during the test, resulting in a certain amount of time loss. The detection equipment of this embodiment is provided with a plurality of independent detection devices 200, and the sampling mechanism 401 can move between the sample rack 340 and the detection chamber 220 of each detection device 200, which can reduce the waiting time of the sampling device 400 and each detection device 200, thereby further improving the detection efficiency.

[0063] refer to Figure 2 and Figure 3Taking a detection device with two independent detection devices 200 as an example, the sampling device 400 first injects samples into the detection chamber 220 (denoted as the first detection chamber) of one of the detection devices 200. While the sample is being tested in the first detection chamber, the sampling device 400 causes the sampling mechanism 401 to move from the position of the first detection chamber to the sample rack 340 to obtain the next sample container 500 and inject the sample into the detection chamber 220 (denoted as the second detection chamber) of the other detection device 200. There is no need to wait for the detection of the first detection chamber to complete, which optimizes the action rhythm and effectively reduces the waiting time of the detection chamber 220. The sampling device 400 injects and removes samples into and from the first and second detection chambers in turn, which also improves the unit time utilization rate of the sampling device 400. By properly setting the beat time, the first detection chamber can complete testing simultaneously (or within a shorter timeframe) when the sample introduction device 400 completes sample introduction into the second detection chamber. In this case, the sample introduction device 400 can move the sampling mechanism 401 located in the second detection chamber directly to the first detection chamber to retrieve the tested sample container 500, which is then moved to the sample rack 340. This reduces the idle movement of the sampling mechanism 401, effectively increasing the intensity of the various device actions, and thus improving testing efficiency. In actual implementation, the number of detection devices 200 can be appropriately configured based on factors such as the specific testing time and the travel distance of the sampling mechanism 401 to reduce idle waiting time and thus improve efficiency.

[0064] Figure 6 is a schematic diagram of the structure of the detection device 200, refer to Figure 6 In some embodiments, the detection chamber 220 includes a main body 221 and a light-shielding door 223. The main body 221 is hollow, forming a detection cavity 222 for accommodating a sample container 500. The main body 221 defines an opening 224 for the sample container 500 to enter and exit the detection cavity 222. The light-shielding door 223 is connected to the main body 221 and can be controlled to open or close the opening 224. The detector 210 is connected to the main body 221 and is configured to detect samples within the detection cavity 222. The detection sensing module also senses the opening and closing of the light-shielding door 223. This is achieved by using a photoelectric switch at the opening 224, which then generates a light-shielding indication signal. In response to the detection indication signal and the light-shielding indication signal, the controller sends control signals to control the opening and closing of the light-shielding door 223, the activation and deactivation of the detector 210, and the sampling mechanism 401 to perform sample placement and retrieval operations in each detection chamber 220. Thus, the coordination among the opening and closing operations of the light-shielding door 223 , the starting and stopping operations of the detector 210 , and the sample injection and sample removal operations of the sampling mechanism 401 is achieved.

[0065] Figure 7 is a structural diagram of the sample delivery device 300, Figure 8 for Figure 7 Schematic diagram of part of the internal structure of the sample delivery device 300, see Figures 1 to 3 ,as well as Figure 7 and Figure 8 In some embodiments, the sample platform 310 is provided with a sampling station 313. The moving mechanism 440 can drive the sampling mechanism 401 to move between the sampling station 313 and the detection chamber 220, thereby transferring the sample container 500 between the detection chamber 220 and the sample rack 340 located at the sampling station 313. When the sample rack 340 moves to the sampling station 313, the sample rack position indication signal emitted by the sample rack sensing module causes the controller to control the sampling mechanism 401 to obtain the sample container 500 from the sample rack 340 at the sampling station 313. When delivering samples, the controller receives the sample rack position indication signal issued by the sample rack sensing module and issues a control signal to control the corresponding actions of the sample rack driving module and / or the sampling device 400. For example, when the sample rack 340 moves to the sampling station 313, the sample rack sensing module issues a positive indication signal indicating that the sample rack 340 is located at the sampling station 313, otherwise it issues a negative indication signal. The controller receives the positive indication signal and controls the sampling device 400 to perform sampling or placing operations on the current sample rack 340. When the controller receives the negative indication signal, it can control the sample driving module to move the sample rack 340 to the sampling station 313.

[0066] In some embodiments, reference Figure 1 and Figure 2 The sample platform 310 can accommodate multiple sample racks 340, and the sample sensing module can sense the sample rack 340 at multiple positions on the sample platform 310. For example, the sample platform 310 is also provided with a loading station for loading the sample rack 340. Position sensors can be set at the sampling station 313 and the loading station. Through sensing at multiple positions, it can be confirmed whether the sampling station 313 has a sample rack 340, so as to instruct the sample rack driving module to move the corresponding sample rack 340 to the sampling position, and whether the loading station has a sample rack 340, so as to issue a prompt to load the sample rack 340 to the loading position of the sample platform 310 to ensure continuous sample delivery.

[0067] refer to Figure 7 and Figure 8The sample platform 310 may further include a carrier plate 311. The sample rack drive module is located below the carrier plate 311. The sample rack drive module includes a sample rack drive assembly 320 and a material-dispensing assembly 330. The material-dispensing assembly 330 is connected to the sample rack drive assembly 320 and has a plurality of finger claws. The carrier plate 311 is provided with strip holes 312 for the finger claws to pass through. The strip holes 312 extend perpendicular to the movement direction of the sampling mechanism 401. Therefore, the material-dispensing assembly 330 can pass through the carrier plate 311 from bottom to top. The sample rack drive assembly 320 drives the material-dispensing assembly 330 to move, thereby pushing the sample rack 340 to move. The sample rack drive assembly 320 can adopt a belt transmission mechanism. The material-dispensing assembly 330 is connected to the belt, so that the reciprocating motion of the belt can realize the back-and-forth motion of the finger claws, thereby pushing the sample rack 340 to move.

[0068] It should be noted that the reference Figure 1 and Figure 2 The sample rack 340 can carry multiple sample containers 500, and the multiple sample containers 500 can be arranged in a set manner according to the actual conveying direction. For example, the sample rack 340 can be provided with multiple positioning parts (such as latches or slots, etc.) for positioning the sample containers 500 in rows along the moving path of the sampling mechanism 401. Thus, the multiple sample containers 500 can be arranged in rows along the moving path of the sampling mechanism 401. When the sample rack drive module moves the sample rack 340 to the sampling station 313, multiple sample containers 500 are arranged along the movement path of the sampling mechanism 401. The sampling mechanism 401 can move to the position corresponding to any sample container 500 to obtain the sample container 500 at that position, thereby injecting the sample into the sample for testing. The sample container 500 that has completed testing can be unloaded to an empty positioning portion in the sample rack 340 for placement, thereby recovering the sample container 500 that has completed testing. The sampling mechanism 401 can also continue to move to the position of any other sample container 500 to be tested, obtain the sample container 500 at that position, and inject the sample into an empty detection device 200 for testing. Therefore, this detection device is suitable for continuous testing of multiple sample containers 500, effectively improving detection efficiency.

[0069] In addition, the sample platform 310 can carry multiple sample racks 340 as mentioned above, and multiple sample racks 340 are arranged side by side along the moving direction. Therefore, the sample rack driving module drives the sample rack 340 to move and can move a sample rack 340 to the sampling station 313 as needed, so as to sample the sample container 500 in the sample rack 340, or put the sample container 500 that has been tested back into the sample rack 340. After the sample container 500 of the current sample rack 340 is tested and recovered, the sample rack 340 is moved out of the sampling station 313 by the sample rack driving module, and then the next sample rack 340 is moved to the sampling station 313, so as to continue sampling and testing, thereby realizing continuous testing of multiple rows of sample containers 500. The detection device can also be applicable to a sample rack 340 in which multiple rows of sample containers 500 are arranged side by side in a single sample rack 340. The multiple rows of sample containers 500 are arranged side by side along the moving direction of the sample rack 340, and the sample containers 500 in each row are arranged in a row along the moving path of the sampling mechanism 401. Therefore, the sample rack driving module drives the sample rack 340 to move and can move one row of sample containers 500 to the sampling station 313 as needed to sample and inject the sample containers 500 in this row. After the sample containers 500 in the current row are tested and the samples are recovered, the sample containers 500 in any other row of the sample rack 340 are moved to the sampling station 313 to continue the sampling and testing. After all the multiple rows of sample containers 500 in the current sample rack 340 are tested and recovered, the sample rack driving module removes the sample rack 340 from the sampling station 313, and then moves the next sample rack 340 to the sampling station 313 to continue the sampling and testing.

[0070] In the above embodiment, the sampling mechanism 401 includes a clamping assembly 410, which has a clamping claw capable of clamping a sample container 500. The sampling mechanism 401 can clamp the sample container 500 through the clamping assembly 410. When injecting or dispensing a sample, the sampling sensing module can be used to sense whether the clamping assembly 410 holds the sample container 500, thereby issuing a sampling indication signal. The controller receives the sampling indication signal issued by the sampling sensing module and issues a control signal to control the moving mechanism 440 to drive the movement of the sampling mechanism 401 and / or the sampling or placing action of the sampling mechanism 401. For example, when the clamping assembly 410 of the sampling mechanism 401 obtains the sample container 500, the sampling sensing module issues a positive indication signal indicating that the sampling mechanism 401 has obtained the sample container 500, and otherwise issues a negative indication signal. The controller receives the positive indication signal and controls the moving mechanism 440 to move the sampling mechanism 401, which has already received the sample container 500, to move the sample container 500 from the sample rack 340 to the detection chamber 220 for sample injection, or to move the sample container 500 from the detection chamber 220 to the sample rack 340 for sample removal. If the gripping assembly 410 of the sampling mechanism 401 has not received the sample container 500, the controller receives the negative indication signal and controls the moving mechanism 440 to move the sampling mechanism 401 to any other position for sampling. The position of the sampling mechanism 401 is sensed by the motion sensing module.

[0071] During sampling, the controller receives the position indication signal of the sampling mechanism 401 from the mobile sensing module and issues a control signal to control the sampling mechanism 401 to perform sampling or placing a sample, and controls the mobile mechanism 440 to drive the sampling mechanism 401 to move to a set position. For example, the position of the sampling mechanism 401 corresponding to the sampling station 313 can be defined as the sampling position 453, and the position corresponding to the detection chamber 220 can be defined as the detection position 454. When the sampling mechanism 401 moves to the sampling position 453 or the detection position 454, the mobile sensing module issues a positive indication signal indicating that the sampling mechanism 401 has reached the set position, otherwise it issues a negative indication signal. The controller receives the positive indication signal and controls the sampling mechanism 401 to perform sampling or placing a sample. The mobile sensing module may include multiple sensors, including at least two position sensors, which are arranged on the moving path of the sampling mechanism 401, thereby enabling sensing at least two positions along the moving path. For example, two position sensors are included to sense one detection position 454 and one sampling position 453 , and the remaining positions can be calculated by the controller according to the position signals.

[0072] Of course, according to the above embodiment, more position sensors may be provided along the moving path of the sampling mechanism 401, thereby enabling sensing of the sampling mechanism 401 at more positions. In some embodiments, the motion sensing module may sense the sampling mechanism 401 at multiple sampling positions 453 along the moving path of the sampling mechanism 401. For example, if multiple sample containers 500 are arranged in a row along the moving path of the sampling mechanism 401 in the sample rack 340, multiple sensing points may be provided along the moving path of the sampling mechanism 401, with the positions of the respective sensing points corresponding to the positions of the respective sample containers 500. A position sensor may be provided at each sensing point, thereby sensing the position of the sampling mechanism 401 at the multiple sampling positions 453, so as to control the movement of the sampling mechanism 401 and the sampling and placing operations at the corresponding positions according to the position indication signal of the sampling mechanism 401.

[0073] In some embodiments, the mobile sensing module can also set sensing points only at two sampling positions 453 on the moving path of the sampling mechanism 401 to sense the sampling mechanism 401. The two positions correspond to the positions at both ends of the row of sample containers 500 respectively. The sampling mechanism 401 can respectively obtain the sample containers 500 located at both ends at these two sampling positions 453. When the sampling mechanism 401 reaches the two sampling positions 453, the mobile sensing module senses and sends a corresponding indication signal. The sampling position 453 between the two positions on the moving path of the sampling mechanism 401 can be determined by controlling the count of the moving mechanism 440, which simplifies the structure and control. Similarly, when multiple detection chambers 220 are provided along the moving path of the sampling mechanism 401 in the detection device 200, multiple detection positions 454 mentioned above can be sensed on the moving path of the sampling mechanism 401, and each detection position 454 corresponds to the position of each detection chamber 220, thereby sensing the sampling mechanism 401 from multiple detection positions 454, so as to control the sampling and placing actions of the sampling mechanism 401 at the corresponding position according to the position indication signal of the sampling mechanism 401.

[0074] Figure 3 for Figure 2 The side view of Figure 4 for Figure 1 The structural diagram of the sample injection device 400 is shown in FIG. Figures 1 to 4 In some embodiments, the sampling device 400 may further include a mounting frame 450. The mounting frame 450 is used to connect to the chassis 100, and the sampling mechanism 401 is movably connected to the mounting frame 450. The moving mechanism 440 is used to drive the sampling mechanism 401 to move relative to the mounting frame 450, thereby achieving movement of the sample container 500. Figure 3 and Figure 4The diagram shows the sampling mechanism 401 positioned at two different positions on the mounting frame 450. The mounting frame 450 is provided with multiple set positions along the transport path for the sample container 500, including the aforementioned sampling position 453 and detection position 454. The moving mechanism 440 is capable of driving the sampling mechanism 401 relative to the mounting frame 450 to each set position. The multiple set positions include at least one detection position 454 and at least one sampling position 453. Therefore, the moving mechanism 440 drives the sampling mechanism 401 relative to the mounting frame 450 to move between the sampling position 453 and the detection position 454 to place and retrieve the sample container 500. The movement of the sampling mechanism 401 facilitates movement of the sample container 500, thereby transferring the sample container 500 between the sample rack 340 and the detection chamber 220. This enables mechanized loading and unloading of the sample container 500. Compared to conventional loading methods using a moving stage, this method eliminates the need for human assistance, is suitable for continuous sample loading and testing, and can effectively improve testing efficiency. In addition, an injection slide 451 and a slider slidably connected to the injection slide 451 can be set on the mounting frame 450, and the sampling mechanism 401 is connected to the slider. The injection slide 451 is parallel to the conveying path of the conveyor belt mechanism 430. The sampling mechanism 401 can be connected to the slider, thereby being able to slide relative to the injection slide 451 to ensure the smooth movement of the sampling mechanism 401.

[0075] In some embodiments, the moving mechanism 440 in the sample feeding device 400 is used to drive the sampling mechanism 401 to move horizontally and vertically. The sample platform 310 and each detection device 200 are located below the path of the sampling mechanism 401's horizontal movement, effectively utilizing the vertical space to form a longitudinal structural layout and reducing the horizontal occupied area. Furthermore, the sample platform 310 and each detection device 200 form a layout consistent with the movement path of the sampling mechanism 401. The sampling mechanism 401 can reach the corresponding positions of the sample platform 310 and each detection device 200 by moving horizontally, resulting in a simple structure and convenient control. The motion sensing module is configured to sense the horizontal and vertical positions of the sampling mechanism 401, respectively, and to send a position indication signal of the sampling mechanism 401 to enable the controller to control the sampling mechanism 401 to take and place the sample container 500. For example, the motion sensing module senses that the sampling mechanism 401 moves in the horizontal direction to the position corresponding to the sample platform 310 or each detection device 200, and sends a position indication signal of the sampling mechanism 401 to enable the controller to control the lifting component 430 to drive the sampling mechanism 401 to move in the vertical direction to perform sampling or placement operations. The motion sensing module senses that the sampling mechanism 401 moves away from the sample platform 310 or each detection device 200 to the set position in the vertical direction, and sends a position indication signal of the sampling mechanism 401 to enable the controller to control the horizontal moving component 441 to drive the sampling mechanism 401 to move horizontally.

[0076] The motion sensing module may include multiple sensors, including at least two horizontal position sensors and at least two vertical position sensors. The horizontal position sensors are disposed on the path along which the sampling mechanism 401 moves horizontally, thereby enabling sensing at least two positions in the horizontal direction. For example, horizontal position sensors may be disposed at one detection position 454 and one sampling position 453, thereby enabling position sensing of the sampling mechanism 401 at these detection positions 454 and 453. The remaining positions may be calculated by the controller based on the position signals. Of course, as can be seen from the above embodiment, multiple horizontal position sensors may also be disposed in the horizontal direction, thereby enabling sensing of the sampling mechanism 401 at multiple positions. The vertical position sensor is disposed on the path along which the sampling mechanism 401 moves vertically, thereby enabling sensing at least two positions in the vertical direction. For example, two sensing positions can be spaced apart along the vertical motion path of the sampling mechanism 401. When the sampling mechanism 401 moves vertically to the lower sensing position, it can clamp the sample rack 340 or the sample container 500 in the detection chamber 220. When the sampling mechanism 401 moves vertically to the upper sensing position, it can move away from the sample rack 340 or the detection device 200 to avoid interference with the sampling mechanism 401 or the sample container 500 during horizontal movement. Vertical position sensors can be provided at each of the two sensing positions along the vertical motion path of the sampling mechanism 401, enabling sensing of the two vertical positions.

[0077] The moving mechanism 440 may include a horizontal moving component 441 and a lifting component 430. The lifting component 430 is used to drive the sampling mechanism 401 to move in the vertical direction to approach or move away from the sample platform 310 or the detection chamber 220. A portion of the horizontal moving component 441 is located in the installation cavity 102, and the other portion passes through the injection port 101 to the outside of the installation cavity 102. The horizontal moving component 441 is used to drive the lifting component 430 and the sampling mechanism 401 to move in the horizontal direction to enter and exit the installation cavity 102, so that the sample container 500 can be transferred between the sample rack 340 and the detection chamber 220. The horizontal moving component 441 drives the sampling mechanism 401 and the lifting component 430 to move in the horizontal direction to reach the sampling position 453 or the detection position 454. The lifting component 430 drives the sampling mechanism 401 to move in the vertical direction at the sampling position 453, and can approach the sample platform 310 to perform sampling or placement operations on the sample rack 340 on the sampling station 313 of the sample platform 310, or move away from the sample platform 310 to avoid interference between the horizontal moving component 441 and the sample rack 340 when driving the sampling mechanism 401 to move horizontally; the lifting component 430 drives the sampling mechanism 401 to move in the vertical direction at the detection position 454, and can approach the detection device 200 to perform sampling or placement operations on the detection chamber 220 of the detection device 200, or move away from the detection device 200 to avoid interference between the horizontal moving component 441 and the detection device 200 when driving the sampling mechanism 401 to move horizontally.

[0078] In some embodiments, the sampling mechanism 401 includes a gripping assembly 410 and a rotating assembly 420. The gripping assembly 410 has a gripping claw capable of gripping a sample container 500 for gripping the sample container 500. The rotating assembly 420 is connected to the gripping assembly 410 and is used to drive the gripping assembly 410 to rotate. Therefore, the sample container 500 can be sampled and the sample container 500 can be rotated to a set angle to obtain a desired posture for sampling and testing. It can also help optimize the structural layout of the detection equipment, improve motion accuracy, and simplify the spatial structure. Specifically, in some embodiments of the detection equipment, the sample container 500 adopts a card-type structure, that is, the thickness of the sample container 500 is significantly smaller than the length and width. Due to the layout of the detection device 200 and other devices and structural parts inside the chassis 100, the sample container 500 needs to enter the detection chamber 220 for testing in a set posture. For example, the sample container 500 needs to enter the detection chamber 220 in a posture with the thickness direction perpendicular to the conveying direction and the width direction consistent with the conveying direction. At this time, if the sampling mechanism 401 is not provided with a rotating component 420, the sample platform 310 needs to deliver the sample container 500 in this posture. In order to realize the continuous transmission of multiple sample containers 500, the sample platform 310 needs to arrange multiple sample containers 500 in the above-mentioned posture in a row along the moving direction of the sampling mechanism 401, that is, arranged along the width direction of the sample container 500, which requires a larger space in the moving direction of the sampling mechanism 401, and the moving path required by the sampling mechanism 401 is also longer.

[0079] To address the aforementioned issues, some testing devices arrange multiple sample containers 500 in a row in the aforementioned position, along a direction perpendicular to the movement path of the sampling mechanism 401. Each time a sample is taken, the sample rack 340 driving mechanism moves the sample rack 340 in a direction perpendicular to the movement path of the sampling mechanism 401, so that one of the sample containers 500 in the row is aligned with the sampling mechanism 401 at the sampling position 453. This enables continuous sample delivery and injection of the sample containers 500, improves the density of the sample containers 500, and reduces the occupied area and the movement path of the sampling mechanism 401. However, in testing devices employing this arrangement, the sample rack 340 driving mechanism is required to drive the sample rack 340 to move the sample container 500 to a position corresponding to the gripping assembly 410 of the sampling mechanism 401 when sampling each sample container 500. This increases the number of motions required during the transport of the sample container 500, and multiple motions can easily result in errors that accumulate, leading to reduced accuracy and sampling failure.

[0080] The detection device of the embodiment of the present invention increases the rotational movement of the gripping assembly 410 through the rotating assembly 420, thereby being able to change the posture of the sample container 500. Therefore, the sample platform 310 is not restricted by the posture required for detection when delivering the sample. Figure 1 and Figure 2The sample containers 500 can be arranged in a row along the moving direction of the sampling mechanism 401. The thickness direction of the sample containers 500 is consistent with the moving direction of the sampling mechanism 401. Since the card-type sample containers 500 have a small thickness, the sample containers 500 can be densely arranged in the moving direction of the sampling mechanism 401, which greatly reduces the occupied space. Moreover, the alignment of each sample container 500 can be achieved through the movement of the sampling mechanism 401, without the need for multiple movements and alignment of the sample rack 340, thereby improving the movement accuracy and helping to simplify the structure.

[0081] In some embodiments, the gripping assembly 410 includes a gripper drive mechanism and a pair of parallel, opposing grippers. The gripper drive mechanism is configured to drive the grippers to increase or decrease the distance between the two grippers while maintaining their parallelism. The gripper assembly 410 is suitable for gripping a sample container 500 having a card-like structure. A sampling sensing module senses whether the gripper assembly 410 is holding the sample container 500, thereby sending a sampling indication signal to the controller. The sampling sensing module can be implemented using simple material presence detection. For example, a sensor (e.g., a photoelectric sensor) is positioned between the grippers to detect the presence of material between the grippers. Furthermore, a gripper position sensor is positioned along the gripper's movement path and when the grippers are in the gripping position (the position when the sample container 500 is gripped between the grippers) to sense whether the grippers are in the gripping position. When the gripper position sensor senses that the grippers are in the gripping position, if the sample container 500 sensor senses that material is present between the grippers, the gripper assembly 410 determines that the sample container 500 is held. Otherwise, the gripper assembly 410 determines that the sample container 500 is not held.

[0082] As can be seen from the above, the detection equipment of the embodiment of the present invention can realize automatic transmission and automatic detection of the sample container 500 through the sample delivery device 300, the sample injection device 400, the detection device 200 and the controller during the sample detection process, thereby reducing manual assistance and effectively improving efficiency.

[0083] The second embodiment of the present invention provides a method for automatically transferring sample containers used in the above-mentioned detection equipment, which can be referred to Figures 1 to 8 , the method comprising:

[0084] Sample delivery: according to the sample rack position indication signal, the sample delivery device 300 is controlled to move the sample rack 340 to the sample loading station 313;

[0085] Sampling: According to the sample rack position indication signal and the detection indication signal, the moving mechanism 440 is controlled to drive the sampling mechanism 401 to move to the sample rack 340 for sampling operation and to move to the detection chamber 220 for sample placement operation;

[0086] Detection: Controlling the detector to detect the sample in the detection chamber 222 according to the detection indication signal;

[0087] Sampling: After the detection is completed, the moving mechanism 440 is controlled to drive the sampling mechanism 401 to move to the detection chamber 220 for sampling operation and move to the sample rack for sample placement operation.

[0088] In the above method, the following sampling method can be employed: multiple sample containers 500 are arranged at intervals along the movement path of the sampling mechanism 401 in the sample rack 340, multiple sampling positions 453 are set at intervals along the movement path of the sampling mechanism 401, and the sampling mechanism 401 is driven to move to one of the multiple sampling positions 453 at a time to inject or remove samples from the sample container 500 at that sampling position 453. Therefore, the sampling mechanism 401 can be aligned with each sample container 500 in the sample rack 340 simply by moving the sampling mechanism 401, simplifying the structure. Furthermore, the spacing between adjacent sampling positions 453 is equal to the spacing between adjacent sample containers 500. Therefore, the movement of the sampling mechanism 401 can be achieved precisely by calculating the number of steps of the stepper motor, simplifying the control method.

[0089] In the above method, when the detection equipment includes multiple independent detection devices 200, the state in which the detection chamber 220 of each detection device 200 is free of sample containers 500 is set as the idle state of the detection chamber 220, and the state in which the detection chamber 220 contains sample containers 500 and the detector 210 has completed detection is set as the completed state of the detection chamber 220. The controller monitors the state of each detection chamber 220. During sample injection, the sampling mechanism 401 is controlled to move, injecting samples into the idle detection chamber 220 and controlling the detector 210 to perform detection. The sampling mechanism 401 is controlled to move, and sample removal is performed from the completed detection chamber 220. In this way, multiple sample containers 500 are injected into different detection chambers 220 by the sampling mechanism 401 for testing. Each sample container 500 is independently tested and, after completion of testing, is removed by the sampling mechanism 401, effectively improving detection efficiency.

[0090] In the above method, a zero position 456 can be set at either end of the movement path of the sampling mechanism 401. When the detection device is turned on, or when any of the detection device 200, the sample delivery device 200, or the sample injection device 400 experiences an abnormality, the sampling mechanism 401 is controlled to move to the zero position 456 and stand by for self-test or manual inspection. A sensor is provided at the zero position 456 to confirm that the sampling mechanism 401 has reached the zero position 456.

[0091] As can be seen from the above, the detection device of the present invention can realize automatic sample container transportation and automatic detection, reduce manual auxiliary operations, thereby improving detection efficiency, and is applicable to the continuous detection of multiple sample containers. The automatic sample container transportation method of the present invention is applied to the above-mentioned detection device, which can realize automatic sample delivery, sample injection, detection, and sample removal of sample containers, effectively improving detection efficiency.

[0092] 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.
