When the sample rack 340 moves to the sampling station 313, the controller controls the sampling mechanism 401 to take the sample container 500 from the sample rack 340 of the sampling station 313 according to the sample rack position indication signal sent by the sample rack sensing module. During sample feeding, the controller receives a sample rack position indication signal sent by the sample rack sensing module and sends a control signal to control corresponding actions of the sample rack driving module and/or the sample introduction device 400, for example, when the sample rack 340 moves to the sampling station 313, the sample rack sensing module sends a positive indication signal that the sample rack 340 is located at the sampling station 313, otherwise, a negative indication signal is sent, the controller receives the positive indication signal and controls the sample introduction device 400 to perform sampling or lofting operations on the current sample rack 340, and when the controller receives the negative indication signal, the controller can control the sample driving module to move the sample rack 340 to the sampling station 313.

The sample rack driving assembly 320 may adopt a belt conveying mechanism, and the material pushing assembly 330 is connected to a belt, so that the reciprocating motion of the belt can realize the back and forth motion of a pusher dog to push the sample rack 340 to move.
It should be noted that, referring to fig. 1 and 2, the sample rack 340 may carry a plurality of sample containers 500, and the plurality of sample containers 500 may be arranged in a predetermined manner according to the actual conveying direction, for example, the sample rack 340 may be provided with a plurality of positioning portions (e.g., detents, slots, etc.) for positioning the sample containers 500 in a row along the moving path of the sampling mechanism 401, so that the plurality of sample containers 500 may be arranged in a row along the moving path of the sampling mechanism 401. When the sample rack driving module moves the sample rack 340 to the sampling station 313, the plurality of sample containers 500 are arranged along the moving path of the sampling mechanism 401, the sampling mechanism 401 can move to a position corresponding to any sample container 500 to obtain the sample container 500 at the position, so as to perform sample injection detection, sample the detected sample container 500 to a vacant positioning part in the sample rack 340 for lofting, so as to recover the detected sample container 500, and further, the sampling mechanism 401 can be continuously moved to any remaining positions of the sample containers 500 to be detected, and the sample containers 500 at the position are obtained and are injected to the vacant detection device 200 for detection. Therefore, the detection device can be suitable for continuous detection of the multiple sample containers 500, and the detection efficiency is effectively improved.
In addition, the sample platform 310 may carry a plurality of the sample racks 340, and the plurality of sample racks 340 are arranged side by side along the moving direction, so that the sample rack driving module drives the sample racks 340 to move, that is, one sample rack 340 can be moved to the sampling station 313 as required, so as to sample the sample containers 500 in the sample rack 340, or the detected sample containers 500 are placed back into the sample rack 340, after the detection of the sample containers 500 in the current sample rack 340 is completed and recovered, the sample rack 340 is moved out from the sampling station 313 through the sample rack driving module, and then the next sample rack 340 is moved to the sampling station 313, so as to continue the sample introduction detection, thereby implementing the continuous detection of the multiple rows of sample containers 500.

In the above embodiment, the sampling mechanism 401 includes the gripping assembly 410, and the gripping assembly 410 has the gripping jaw capable of gripping the sample container 500 for gripping the sample container 500.

The controller receives the positive indication signal and controls the moving mechanism 440 to drive the sampling mechanism 401 of the acquired sample container 500 to move, so as to move the sample container 500 from the position of the sample rack 340 to the detection chamber 220 for sample introduction, or move the sample container 500 from the detection chamber 220 to the sample rack 340 for sample discharge; when the gripping assembly 410 of the sampling mechanism 401 does not take 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 of the other positions for sampling operation. The position of sampling mechanism 401 is sensed by a motion sensing module.
During sampling, the controller receives a sampling mechanism 401 position indication signal sent by the motion sensing module, and sends a control signal to control the sampling mechanism 401 to perform sampling or lofting operation, and controls the moving mechanism 440 to drive the sampling mechanism 401 to move to a set position, for example, a position of the sampling mechanism 401 corresponding to the sampling station 313 may be defined as a sampling position 453, a position corresponding to the detection chamber 220 may be defined as a detection position 454, when the sampling mechanism 401 moves to the sampling position 453 or the detection position 454, the motion sensing module sends a positive indication signal that the sampling mechanism 401 reaches the set position, otherwise, a negative indication signal. The controller receives the positive indication signal and controls the sampling mechanism 401 to perform sampling or lofting operations. The motion sensing module may include a plurality of sensors, and the plurality of sensors includes at least 2 position sensors, and the position sensors are disposed on a moving path of the sampling mechanism 401, so that sensing of at least 2 positions can be performed on the moving path. For example, 2 position sensors are included for sensing 1 detection position 454 and 1 sampling position 453, and the remaining positions can be calculated by the controller from the position signals.
Of course, according to the above embodiment, more position sensors may be provided on the moving path of the sampling mechanism 401, so that the sampling mechanism 401 can be sensed at more positions. In some embodiments, the movement sensing module may sense the sampling mechanism 401 at a plurality of sampling positions 453 on the moving path of the sampling mechanism 401, for example, in the case that a plurality of sample containers 500 are arranged in a row along the moving path of the sampling mechanism 401 in the sample rack 340, a plurality of sensing points may be arranged on the moving path of the sampling mechanism 401, the positions of the sensing points correspond to the positions of the sample containers 500, respectively, and a position sensor may be arranged at each sensing point, thereby performing position sensing on the sampling mechanism 401 at the plurality of sampling positions 453, so as to control the movement of the sampling mechanism 401 and the sampling and lofting operations at the corresponding positions according to the position indication signal of the sampling mechanism 401.
In some embodiments, the movement sensing module may also only provide sensing points at two sampling positions 453 on the moving path of the sampling mechanism 401, so as to sense the sampling mechanism 401, the two positions correspond to the positions of the two ends of the row of sample containers 500, the sampling mechanism 401 can respectively acquire the sample containers 500 at the two ends at the two sampling positions 453, when the sampling mechanism 401 reaches the two sampling positions 453, the movement sensing module senses and sends out corresponding indication signals, and the sampling position 453 between the two positions on the moving path of the sampling mechanism 401 can be determined by controlling the counting of the moving mechanism 440, thereby simplifying the structure and the control. Similarly, in the detection apparatus 200, when a plurality of detection chambers 220 are provided along the movement path of the sampling mechanism 401, a plurality of detection positions 454 described above are sensed on the movement path of the sampling mechanism 401, and each detection position 454 corresponds to the position of each detection chamber 220, so that the sampling mechanism 401 is sensed from the plurality of detection positions 454, and the sampling and setting operation of the sampling mechanism 401 at the corresponding position is controlled based on the position instruction signal of the sampling mechanism 401.
Fig. 3 is a side view of fig. 2, and fig. 4 is a schematic structural diagram of the sample introduction device 400 of fig. 1, and referring to fig. 1 to 4, in some embodiments, the sample introduction device 400 may further include a mounting bracket 450. The mounting block 450 is configured to be coupled to the housing 100, the sampling mechanism 401 is movably coupled to the mounting block 450, and the moving mechanism 440 is configured to drive the sampling mechanism 401 to move relative to the mounting block 450, thereby moving the sample container 500. Fig. 3 and 4 show the sampling mechanism 401 in two different positions on the mounting block 450. The mount 450 is provided with a plurality of setting positions including the sampling position 453 and the detection position 454 described above along the transport path of the sample container 500, and the moving mechanism 440 can drive the sampling mechanism 401 to move to each setting position with respect to the mount 450. The plurality of setting positions include at least one detecting position 454 and at least one sampling position 453, so that the sampling mechanism 401 is driven by the moving mechanism 440 to move to the sampling position 453 and the detecting position 454 relative to the mounting rack 450 to take and place the sample container 500, and the movement of the sampling mechanism 401 realizes the movement of the sample container 500, thereby transferring the sample container 500 between the sample rack 340 and the detecting chamber 220, and realizing the mechanized sample feeding and discharging of the sample container 500. Compared with the conventional mode of sample introduction through movement of the carrying platform, the sample introduction device does not need personnel auxiliary operation, is suitable for continuous sample introduction detection, and can effectively improve the detection efficiency. In addition, a sample injection slide rail 451 and a slide block connected to the sample injection slide rail 451 in a sliding manner can be arranged on the mounting frame 450, the sampling mechanism 401 is connected to the slide block, the sample injection slide rail 451 is parallel to the conveying path of the conveyor belt mechanism 430, and the sampling mechanism 401 can be connected to the slide block, so that the sampling mechanism 401 can slide relative to the sample injection slide rail 451, and the moving stability of the sampling mechanism 401 is ensured.
In some embodiments, the moving mechanism 440 in the sample introduction device 400 is used to drive the sampling mechanism 401 to move in the horizontal direction and to move in the vertical direction, and the sample platform 310 and each detection device 200 are located below the path of the sampling mechanism 401 moving in the horizontal direction, so that the space in the vertical direction can be effectively utilized to form a longitudinal structural layout, and the occupied area in the horizontal direction is reduced. And the sample platform 310 and each detection device 200 form a layout consistent with the moving path of the sampling mechanism 401, and the sampling mechanism 401 can reach the corresponding positions of the sample platform 310 and each detection device 200 by moving along the horizontal direction, so that the structure is simple and the control is convenient. The motion sensing module is configured to respectively sense a position of the sampling mechanism 401 moving in a horizontal direction and a position of the sampling mechanism 401 moving in a vertical direction, and send a signal indicating the position of the sampling mechanism 401 to enable the controller to control the sampling mechanism 401 to pick and place the sample container 500. For example, the mobile sensing module senses that the sampling mechanism 401 moves along the horizontal direction to reach the position corresponding to the sample platform 310 or each detection device 200, sends a signal indicating the position of the sampling mechanism 401 to enable the controller to control the lifting assembly 430 to drive the sampling mechanism 401 to move along the vertical direction, so as to perform sampling or lofting operations, the mobile sensing module senses that the sampling mechanism 401 moves away from the sample platform 310 or each detection device 200 along the vertical direction to a set position, and sends a signal indicating the position of the sampling mechanism 401 to enable the controller to control the horizontal movement assembly 441 to drive the sampling mechanism 401 to move horizontally.
The movement sensing module may include a plurality of sensors including at least 2 horizontal position sensors and at least 2 vertical position sensors, the horizontal position sensors being disposed on a path along which the sampling mechanism 401 moves in the horizontal direction, thereby enabling sensing of at least 2 positions in the horizontal direction. For example, a horizontal position sensor may be provided at 1 detection position 454 and 1 sampling position 453 to perform position sensing of the sampling mechanism 401 at the 1 detection position 454 and the 1 sampling position 453, and the remaining positions may be calculated by the controller based on the position signal, but it is needless to say that a plurality of horizontal position sensors may be provided in the horizontal direction according to the above-described embodiment, and the sampling mechanism 401 may be sensed at a plurality of positions. The vertical position sensor is provided on a path along which the sampling mechanism 401 moves in the vertical direction, thereby enabling sensing of at least 2 positions in the vertical direction. For example, 2 sensing positions may be provided at intervals on a path along which the sampling mechanism 401 moves in the vertical direction, the sampling mechanism 401 can grip the sample rack 340 or the sample container 500 in the detection chamber 220 when moving to the sensing position located below in the vertical direction, and the sampling mechanism 401 can be away from the sample rack 340 or the detection device 200 when moving to the sensing position located above in the vertical direction, so as to avoid interference of the sampling mechanism 401 or the sample container 500 when moving horizontally. Vertical position sensors can be respectively arranged at 2 sensing positions on the path of the sampling mechanism 401 moving along the vertical direction, so that 2 vertical positions can be sensed.
The moving mechanism 440 may include a horizontal moving assembly 441 and a lifting assembly 430, the lifting assembly 430 is used for driving the sampling mechanism 401 to move in a vertical direction to be close to or far away from the sample platform 310 or the detection chamber 220, one part of the horizontal moving assembly 441 is located in the installation cavity 102, and the other part of the horizontal moving assembly passes through the sample inlet 101 to the outside of the installation cavity 102, and the horizontal moving assembly 441 is used for driving the lifting assembly 430 and the sampling mechanism 401 to move in a 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 assembly 441 drives the sampling mechanism 401 and the lifting assembly 430 to move along the horizontal direction to reach the sampling position 453 or the detection position 454, the lifting assembly 430 drives the sampling mechanism 401 to move along the vertical direction at the sampling position 453, and the sampling mechanism can be close to the sample platform 310 so as to sample or loft the sample rack 340 on the sampling station 313 of the sample platform 310, or can be far away from the sample platform 310 so as to avoid interference with the sample rack 340 when the horizontal moving assembly 441 drives the sampling mechanism 401 to move horizontally; the lifting assembly 430 drives the sampling mechanism 401 to move vertically at the detection position 454, so as to approach the detection device 200 and perform sampling or lofting operation on the detection chamber 220 of the detection device 200, or move away from the detection device 200, thereby preventing the horizontal moving assembly 441 from interfering with the detection device 200 when the sampling mechanism 401 is driven to move horizontally.
In some embodiments, the sampling mechanism 401 includes a gripping assembly 410 and a rotating assembly 420, the gripping assembly 410 has a gripping jaw capable of gripping the sample container 500 and is used for gripping the sample container 500, and the rotating assembly 420 is connected to the gripping assembly 410 and is used for driving the gripping assembly 410 to rotate, so that the sample container 500 can be sampled, and the sample container 500 can be rotated by a set angle to obtain a required pose so as to facilitate sample introduction detection. Specifically, in the detection apparatus of some embodiments, the sample container 500 adopts a snap-in structure, that is, the thickness of the sample container 500 is significantly smaller than the length and width dimensions, and due to the layout of the detection device 200 and other devices, structural members, etc. inside the chassis 100, the sample container 500 needs to enter the detection chamber 220 for detection in a set pose. For example, it is necessary for the sample container 500 to enter the detection chamber 220 in a posture in which the thickness direction is perpendicular to the conveyance direction and the width direction coincides with the conveyance direction. At this time, if the rotary assembly 420 is not provided in the sampling mechanism 401, the sample platform 310 needs to feed the sample containers 500 in the posture, and in order to realize continuous conveyance of the multiple sample containers 500, the sample platform 310 needs to arrange the multiple sample containers 500 in the posture in a row along the moving direction of the sampling mechanism 401, that is, in the width direction of the sample containers 500, a large space needs to be occupied in the moving direction of the sampling mechanism 401, and the moving path required by the sampling mechanism 401 is also long.
In order to solve the above problems, some inspection apparatuses arrange a plurality of sample containers 500 in a row in the above-described posture in a direction perpendicular to the movement path of the sampling mechanism 401, and at each sampling, move the sample rack 340 in the direction perpendicular to the movement path of the sampling mechanism 401 by the sample rack 340 driving mechanism to correspond one of the sample containers 500 in the row to the sampling mechanism 401 located at the sampling position 453, can realize continuous sample feeding and feeding of the sample containers 500, and can increase the density of the sample containers 500, and reduce the occupied area and the movement path of the sampling mechanism 401. However, with the detection apparatus adopting this arrangement, when each sample container 500 is sampled, the sample rack 340 needs to be driven by the sample rack 340 driving mechanism to move the sample container 500 to the position corresponding to the gripping assembly 410 of the sampling mechanism 401, which increases the dimension of the movement required in the process of conveying the sample container 500, and multiple movements are easy to generate error superposition, thereby causing sampling failure due to accuracy reduction.
In the detection apparatus according to the embodiment of the present invention, the rotary motion of the gripping assembly 410 is added by the rotary assembly 420, so that the posture of the sample container 500 can be changed, and therefore, the sample platform 310 is not limited by the posture required for detection when delivering samples, referring to fig. 1 and 2, the 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, and because the thickness dimension of the cassette type sample containers 500 is small, the sample containers 500 arranged densely can be moved in the moving direction of the sampling mechanism 401, the occupied space is greatly reduced, and the alignment of each sample container 500 can be realized by the movement of the sampling mechanism 401, and the multiple movement alignment of the sample rack 340 is not required, thereby improving the motion accuracy and facilitating the simplification of the structure.
In some embodiments, the gripping assembly 410 includes a jaw driving mechanism and a pair of jaws disposed in parallel and opposite to each other, the jaw driving mechanism is used for driving the jaws to move so as to increase or decrease the distance between the two jaws and keep the jaws parallel, the jaw driving mechanism is adapted to grip the sample container 500 in the cassette structure, and the sampling sensing module senses whether the gripping assembly 410 grips the sample container 500, so as to send a sampling indication signal to the controller. The sample response module accessible simple material detection can realize, for example, set up inductor (like photoelectric sensor) between the clamping piece and be used for detecting whether there is material between the clamping jaw, and on the moving path of clamping piece and the clamping piece is located clamping position (the position when centre gripping sample container 500 between the clamping piece) and sets up clamping piece position sensor, be used for sensing whether the clamping piece is located clamping position, when clamping piece position sensor sensing when the clamping piece is located clamping position, if there is material between the clamping piece to sample container 500 sensor sensing, can judge to press from both sides the centre gripping among the clamping subassembly 410 and have sample container 500, otherwise judge to press from both sides and do not press from both sides in the clamping subassembly 410 and have sample container 500.
As can be seen from the above, in the sample detection process, the detection apparatus according to the embodiment of the present invention can realize automatic transmission and automatic detection of the sample container 500 through the sample feeding device 300, the sample injection device 400, the detection device 200, and the controller, so that manual assistance is reduced, and efficiency is effectively improved.
In a second aspect, the embodiment of the present invention provides an automatic sample container conveying method applied to the above-mentioned detection apparatus, which can refer to fig. 1 to 8, and the method includes:
sample feeding: controlling the sample feeding device 300 to move the sample rack 340 to the sample feeding station 313 according to the sample rack position indication signal;
sample introduction: 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 lofting operation;
and (3) detection: controlling the detection of the sample in the detection cavity 222 by the detector according to the detection indication signal;
sampling: after the detection is completed, the control moving mechanism 440 drives the sampling mechanism 401 to move to the detection chamber 220 for sampling operation and to move to the sample rack for lofting operation.
In the above method, the following sample introduction method can be adopted: a plurality of sample containers 500 are arranged in the sample rack 340 at intervals along the moving path of the sampling mechanism 401, a plurality of sampling positions 453 are arranged at intervals along the moving path of the sampling mechanism 401, and the sampling mechanism 401 is driven to move to one of the sampling positions 453 at a time so as to sample the sample container 500 at the sampling position 453. Therefore, the position of each sample container 500 of the sampling mechanism 401 and the sample rack 340 can be aligned by the movement of the sampling mechanism 401, the structure is simplified, and the distance between the adjacent sampling positions 453 is equal to the interval between the adjacent sample containers 500, so that the movement of the sampling mechanism 401 can be accurately moved by the step number calculation of the stepping motor, and the control method is simplified.
In the above method, when the detection apparatus includes a plurality of detection devices 200 for independent detection, the state in which no sample container 500 is present in the detection chamber 220 of each detection device 200 is set as the idle state of the detection chamber 220, the state in which the detection chamber 220 contains the sample container 500 and the detection of the detector 210 is completed is set as the complete state of the detection chamber 220, and the state of each detection chamber 220 is monitored by the controller. During sample injection, the sampling mechanism 401 is controlled to move, the detection chamber 220 in an idle state is subjected to sample injection operation, and the detector 210 is controlled to perform detection operation; the sampling mechanism 401 is controlled to move, the detection chamber 220 in the finished state is subjected to sampling operation, therefore, the plurality of sample containers 500 are respectively sampled into different detection chambers 220 by the sampling mechanism 401 to be detected, each sample container 500 is independently detected, and the samples are respectively sampled by the sampling mechanism 401 after the detection is finished, so that the detection efficiency can be effectively improved.
In the above method, a zero point position 456 may be provided at any one of the two ends of the moving path of the sampling mechanism 401, and when the detection device is turned on or when any one of the detection device 200, the sample feeding device 200, and the sample injection device 400 is abnormal, the sampling mechanism 401 is controlled to move to the zero point position 456 and stand by for self-checking or manual inspection. Zero position 456 sets a sensor to confirm that sampling mechanism 401 reaches this zero position 456.
Therefore, the detection equipment can realize automatic conveying and automatic detection of the sample containers, reduces manual auxiliary operation, improves detection efficiency, and is suitable for continuous detection of multiple sample containers. The automatic sample container conveying method is applied to the detection equipment, can realize automatic sample conveying, sample introduction, detection and sample discharge of the sample containers, and can effectively improve the detection efficiency.
