[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] In the related art, the blood type analyzer includes a centrifugal mechanism and a carrier arranged on the centrifugal mechanism. The carrier can be used to load reaction carriers such as blood type cards and microplates. The centrifugal mechanism can drive the carrier and the reaction carrier inside it to centrifugal movement. The blood type analyzer can also use a manipulator to grab and transfer the reaction carrier inside the carrier.

[0037] Since the carrier after centrifugal movement is prone to tilt relative to the centrifugal mechanism, the reaction carrier in the carrier will also tilt, which will affect the robot's grasping and transferring steps of the reaction carrier or the steps of adding samples / reagents to the reaction carrier, and thus affect the normal operation of the blood type analyzer.

[0038] The present invention provides a righting mechanism 10 for righting a carrier 30. The carrier can be configured as a blood type card carrier, and the inner travel has a accommodating space with a top opening for loading blood type cards. In some embodiments, the carrier can also be used to load microplates, etc., which is not limited here.

[0039] See also Figures 1 to 3In one embodiment of the present invention, the positioning mechanism 10 includes:

[0040] A normal position lever 11, wherein the normal position lever 11 has a normal position end 111; and

[0041] A driving assembly 12, wherein the driving assembly 12 is drivingly connected to the alignment lever 11, so that the alignment lever 11 has a first position spaced apart from the carrier 30 and a second position abutting against the carrier 30;

[0042] When the alignment lever 11 is at the second position, the end surface of the alignment end 111 is vertically disposed for contacting with the outer side surface of the carrier 30 to adjust the carrier 30 to a vertical state.

[0043] The positioning mechanism 10 of the technical solution of the present invention includes a positioning lever 11 and a driving component 12 driven and connected to the positioning lever 11. The driving component 12 can drive the positioning lever 11 to be movably arranged relative to the carrier 30 so that the positioning lever 11 can have a first position and a second position in its movable range. Specifically, the alignment lever 11 has an alignment end 111. When the alignment lever 11 is in the first position, the alignment lever 11 is located on the side of the carrier 30 to avoid interference between the alignment lever 11 and the carrier 30 when the carrier 30 moves. When the alignment lever 11 moves to the second position, the end face of the alignment end 111 of the alignment lever 11 abuts against the outer side face of the carrier 30. Since the end face of the alignment end 111 is extended in the vertical direction at this time, the side face of the carrier 30 abutting against it can also be arranged in a vertical direction, so that the carrier 30 can be straightened to a vertical state under the drive of the alignment lever 11, thereby realizing the position correction of the carrier 30, so that the blood type analyzer 100 can work normally.

[0044] Furthermore, since the positioning mechanism 10 of the present invention controls the positioning lever 11 to accurately move to the second position by the driving component 12 during the righting operation, and since the second position is relatively fixed relative to the blood type analyzer 100, it can ensure that the carrier 30 can be righted to the same vertical state each time, which is beneficial to ensuring the consistency of the righting effect of the carrier 30 of the positioning mechanism 10 of the present invention.

[0045] The alignment lever 11 may be a rod structure extending in a straight line, and the alignment end 111 for abutting the carrier 30 is formed by its side or end. The alignment lever 11 may also be configured as a block or other shape, which is not limited here. In order to ensure the alignment effect of the alignment lever 11, the size of the alignment end 111 may be close to or larger than the side size of the carrier 30, so that the two can fully contact each other when abutting each other; and the shape of the alignment end 111 may be configured to imitate the side shape of the carrier 30, so that the two can form a good match when abutting each other.

[0046] See also Figure 2 In an embodiment of the present invention, the driving assembly 12 comprises:

[0047] a connecting member 121, wherein the connecting member 121 is connected to one end of the righting lever 11 so as to move synchronously with the righting lever 11; and

[0048] The driving member 122 is drivingly connected to the connecting member 121 and is used to drive the connecting member 121 to move, so as to drive the normal position lever 11 to switch between the first position and the second position.

[0049] The driving member 122 may be configured as a rotational driving mechanism, which drives the connecting member 121 to rotate, thereby driving the positioning lever 11 to rotate toward or away from the carrier 30, thereby realizing the switching movement of the positioning lever 11 between its first position and the second position.

[0050] Of course, the technical solution of the present invention is not limited thereto. In some embodiments, the driving member 122 may also be configured as a linear driving mechanism such as a screw driving mechanism, a telescopic cylinder, etc. The driving member 122 drives the connecting member 121 to reciprocate in a linear direction, so as to drive the alignment lever 11 to move toward or away from the carrier 30 in a linear translational manner, thereby realizing the switching movement of the alignment lever 11 between its first position and the second position; or, the driving assembly 12 may also include a plurality of driving members 122, and the plurality of driving members 122 include the linear driving mechanism or the rotation driving mechanism in the aforementioned embodiment, so that the alignment lever 11 can rotate or translate in multiple axis directions, so as to improve the degree of freedom of the alignment lever 11. The specific implementation method can be set according to actual needs and is not limited here.

[0051] See also Figure 2 In an embodiment of the present invention, the driving member 122 comprises a rotatable driving shaft, and the connecting member 121 is drivingly connected to the driving shaft so as to rotate around the axial direction of the driving shaft under the driving of the driving shaft;

[0052] The central axis of the connecting member 121 is coaxial with the axis of the driving shaft, and the correcting lever 11 is eccentrically arranged relative to the driving shaft.

[0053] Among them, the driving member 122 can be configured as a rotating motor, and the driving shaft of the rotating motor extends in the vertical direction and is drivingly connected to the connecting member 121, so that the connecting member 121 can be rotatably arranged around the vertical direction; further, by connecting the connecting member 121 and the positioning lever 11, the connecting member 121 can drive the positioning lever 11 to rotate around the vertical direction under the drive of the driving member 122, so that the positioning lever 11 can be displaced in the horizontal direction during rotation, so as to move toward the side of the carrier 30 to the second position, so that the end face of the positioning end 111 of the positioning lever 11 can abut against the outer side face of the carrier 30, or, the positioning lever 11 can move away from the carrier 30 in the horizontal direction to the first position during rotation, so as to avoid the carrier 30.

[0054] Furthermore, the central axis of the connecting member 121 is coaxially arranged with the axis of the driving shaft, and the correcting lever 11 is eccentrically arranged relative to the driving shaft.

[0055] Specifically, a shaft hole is provided at the center of the connecting member 121 for sleeve mounting of the driving shaft, and the positioning lever 11 is located at the periphery of the connecting member 121 and is arranged at intervals relative to the center of the connecting member 121, so that the positioning lever 11 can be arranged eccentrically relative to the driving shaft. In this way, when the driving shaft rotates around its axial direction, it can be ensured that the positioning lever 11 is displaced in the horizontal direction.

[0056] Furthermore, in some embodiments, the connecting member 121 can be configured as a rotationally symmetrical image such as a circle, an ellipse, etc., and the drive shaft is located at its rotation center. In this configuration, the connecting member 121 can be rotated around its rotation center, and when the connecting member 121 rotates around its rotation center by a certain angle and converts to another orientation, its contour can match its contour in the previous orientation. In this way, it is helpful to reduce the rotation space required for the connecting member 121.

[0057] Of course, the technical solution of the present invention is not limited thereto. In some embodiments, the central axis of the connecting member 121 and the central axis of the positioning lever 11 can be eccentrically arranged relative to the driving shaft, so that when the driving shaft rotates around its axial direction, the positioning lever 11 can be ensured to be displaced in the horizontal direction. The specific implementation method can be set according to actual needs and is not limited here.

[0058] See also Figure 2In the embodiment of the present invention, the end surface of the alignment end 111 is set in an arc shape. It can be understood that by making the end surface of the alignment end 111 of the alignment lever 11 have a certain curvature, it is beneficial for the alignment lever 11 to smoothly abut against the side of the carrier 30 through the alignment end 111, thereby preventing the risk of a large collision between the two during the alignment process.

[0059] See also Figure 2 In an embodiment of the present invention, the alignment mechanism 10 further includes a mounting bracket 123, wherein the mounting bracket 123 has a mounting surface 123a and a mounting space 123b located below the mounting surface 123a, and the mounting surface 123a is provided with an avoidance hole connected to the mounting space 123b;

[0060] The connecting member 121 is movably disposed above the mounting surface 123 a , the driving member 122 is disposed in the mounting space 123 b , and the driving shaft is inserted into the avoidance hole to be drivingly connected to the connecting member 121 .

[0061] In some embodiments, the mounting bracket 123 may specifically include a top plate, a side plate, and a bottom plate connected in sequence to enclose a mounting space 123b for mounting the driver 122, and the top plate is provided with an escape hole. The driver 122 may be directly mounted on the bottom side of the top plate so that its driving shaft is docked with the escape hole on the top plate and exposed above the top plate. The driver 122 may also be mounted on the side plate or the bottom plate, which is not limited here.

[0062] Furthermore, the mounting bracket 123 can also serve as a mounting base for other components of the alignment mechanism 10, such as a detection assembly, etc. In this way, the various components of the alignment mechanism 10 can be integrated on the same mounting bracket 123 to form a modular design, thereby facilitating the coordinated installation of the alignment mechanism 10 and the external structure.

[0063] See also Figure 2 In an embodiment of the present invention, the alignment mechanism 10 further includes an alignment detection component 13 for detecting whether the alignment lever 11 moves to the first position and / or the second position.

[0064] Among them, the in-position detection component 13 can detect whether the positioning lever 11 has moved into position by means of contact detection. For example, pressure sensors are respectively arranged at the positions of the two ends of the active stroke of the positioning lever 11, and whether the positioning lever 11 has moved to the first position or the second position correspondingly is detected by means of whether the pressure sensor is in contact with the positioning lever 11.

[0065] Of course, the technical solution of the present invention is not limited thereto. In some embodiments, the in-position detection component 13 may also detect whether the positioning lever 11 has moved into position by non-contact detection, for example, by providing a photoelectric detection component in the embodiments described later.

[0066] See also Figure 2 In an embodiment of the present invention, the in-place detection component 13 includes:

[0067] A sensing member 131, wherein the sensing member 131 is drivingly connected to the driving assembly 12 so as to rotate synchronously with the positioning lever 11 under the driving of the driving assembly 12; and

[0068] The induction switch 132 is located on the peripheral side of the correcting lever 11, and the induction end of the induction switch 132 is located on the moving path of the induction member 131, and is used to detect whether the induction member 131 moves to the first position and / or the second position.

[0069] Specifically, the sensing element 131 can be specifically configured as a photoelectric baffle, and the sensing switch 132 can be specifically configured as a photoelectric switch, and the photoelectric switch has a detection slot for forming its detection end. When the photoelectric baffle moves into the detection slot, the photoelectric switch can be triggered, and it can be detected that the sensing element 131 has moved to the position where the photoelectric switch is located.

[0070] In some embodiments, the sensing member 131 may be directly disposed on the alignment lever 11 and protrude toward the side of the alignment lever 11, so that when the driving assembly 12 drives the alignment lever 11 to rotate, the alignment lever 11 can drive the sensing member 131 to rotate synchronously with it, thereby realizing indirect driving of the driving assembly 12 and the sensing member 131; of course, the sensing member 131 may also be directly connected to the driving assembly 12, for example, the sensing member 131 may be disposed on the connecting member 121 of the driving assembly 12 in the aforementioned embodiment and spaced apart from the alignment lever 11, so that when the driving member 122 of the driving assembly 12 drives the connecting member 121 to rotate, the connecting member 121 can simultaneously drive the alignment lever 11 and the sensing member 131 to rotate synchronously. The specific implementation method can be set according to actual needs and is not limited here.

[0071] See also Figure 2 In the embodiment of the present invention, two sensing switches 132 are provided, and the two sensing switches 132 are arranged at intervals on the peripheral side of the normal position lever 11;

[0072] When the normal position lever 11 is switched to the first position and the second position respectively, the sensing member 131 is disposed opposite to the sensing ends of the two sensing switches 132 respectively.

[0073] Specifically, the two sensing switches 132 include a first sensing switch 132a provided for the sensing sheet corresponding to when the alignment lever 11 is in the first position, and a second sensing switch 132b provided for the sensing sheet corresponding to when the alignment lever 11 is in the first position. When the first sensing switch 132a is triggered by the sensing element 131 and the second sensing switch 132b is not triggered, the detection result is that the alignment lever 11 is in the second position, and at this time, the alignment lever 11 can be moved into position and complete the straightening of the carrier 30.

[0074] Similarly, when the second induction switch 132b is triggered by the induction member 131 and the first induction switch 132a is not triggered, the detection result is that the alignment lever 11 is in the first position, and at this time, the centrifugal mechanism 20 of the blood type analyzer 100 can drive the carrier 30 to move to avoid interference between the carrier 30 and the alignment mechanism 10. In this way, the triggering status of the two induction switches 132 can be determined at the same time to avoid the risk caused by a single failure of the alignment mechanism 10.

[0075] The present invention further provides a blood type analyzer 100, which includes a carrier 30 and a positioning mechanism 10. The specific structure of the positioning mechanism 10 refers to the above embodiment. Since the blood type analyzer 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0076] See also Figures 1 to 3 In an embodiment of the present invention, the blood type analyzer 100 further includes a centrifugal mechanism 20, and the alignment mechanism 10 is located on the peripheral side of the centrifugal mechanism 20;

[0077] The centrifugal mechanism is provided with a plurality of carriers 30 along the same circumferential direction, which are used to drive the carriers 30 to rotate around the vertical direction and to drive the carriers 30 to approach the alignment mechanism 10 so as to be arranged opposite to the alignment mechanism 10 along the horizontal direction.

[0078] Specifically, the centrifugal mechanism 20 can be configured as a centrifugal turntable, and a plurality of carriers 30 can be rotatably arranged on the peripheral edge of the centrifugal turntable in a mounted manner, but is not limited to. The reaction carrier can be loaded through the carrier 30. The reaction carrier can be configured as a blood type card, a microplate, etc., but is not limited to it, which is not limited here.

[0079] In a feasible embodiment, the blood type analyzer 100 can be configured as a large blood type analyzer 100, and has separately arranged centrifugal mechanism 20, reading mechanism and other mechanisms. After the centrifugal mechanism 20 of the blood type analyzer completes the centrifugation of the reaction carrier, the reaction carrier in the carrier 30 can be grabbed by a robot arm and transferred to the reading mechanism of the blood type analyzer for subsequent reading.

[0080] In this embodiment, by setting the alignment mechanism 10 on the circumference of the centrifugal mechanism 20, the alignment end 111 of the alignment mechanism 10 can be movably arranged in the horizontal direction and has a first position and a second position on its movable range, and the first position is arranged away from the centrifugal mechanism 20, and the second position is arranged close to the carrier of the centrifugal mechanism 20. Before the centrifugal mechanism 20 drives the carrier 30 to rotate around the vertical direction, the alignment end 111 of the alignment mechanism 10 can be as follows Figure 3 As shown, it moves to the first position to avoid interference with the centrifugal mechanism 20 and the carrier 30 which are in motion.

[0081] After the centrifugation process of the blood type card is completed, the centrifugal mechanism 20 can also make the carrier 30 approach the alignment mechanism 10 through rotational movement, so that the carrier 30 can be arranged horizontally relative to the alignment mechanism 10 after stopping the rotation. At this time, the alignment end 111 of the alignment mechanism 10 can be as shown in FIG. Figure 1 As shown, it moves to the second position, so that its upright end 111 abuts against and pushes the outer wall of the carrier 30, and straightens the carrier 30 to a vertical state, so that the robot arm can accurately grasp the reaction carrier in the carrier 30, and transfer the reaction carrier to other mechanisms of the blood type analyzer 100, such as the reading mechanism, for subsequent processing.

[0082] It should be noted that, in the technical solution of the present invention, while controlling the centrifugal mechanism 20 to drive the carrier 30 to approach the straightening mechanism 10, the straightening end 111 of the straightening mechanism 10 is also controlled to move from the first position to the second position, so that the carrier 30 and the straightening mechanism 10 can move into position simultaneously or nearly simultaneously and cooperate with each other, which is beneficial to ensure the straightening effect of the straightening mechanism 10 on the carrier 30.

[0083] Furthermore, in this embodiment, the centrifugal mechanism 20 can drive several carriers 30 to approach a positioning mechanism 10 in turn, so that the positioning mechanism 10 can straighten the several carriers 30 in turn, and use the robot to grab and transfer the reaction carriers in the straightened carriers 30 in turn.

[0084] Of course, the technical solution of the present invention is not limited to this. The blood type analyzer 100 can also be provided with a plurality of alignment mechanisms 10 on the circumferential side of the centrifugal mechanism 20. The plurality of alignment mechanisms 10 are arranged in sequence along the circumferential direction of the centrifugal mechanism 20. Each alignment mechanism 10 corresponds to a carrier 30. After the centrifugation process of the blood type card is completed, the plurality of carriers 30 on the centrifugal mechanism 20 can be synchronously aligned by the plurality of alignment mechanisms 10. Furthermore, the reaction carriers in the plurality of carriers 30 can be synchronously grasped and transferred by a plurality of manipulators to improve the working efficiency of the blood type analyzer 100. This is not limited here.

[0085] In another feasible embodiment, the blood type analyzer 100 may also adopt an integrated design, in which the centrifugal mechanism 20 is integrated with the sample loading module, the judgment module, etc., so that the carrier can cooperate with the centrifugal mechanism 20 to complete the sample loading, judgment and other steps, and then the reaction carrier that completes the experiment in the carrier is grabbed by a robot arm to be removed from the centrifugal mechanism for disposal.

[0086] In this embodiment, by providing a positioning mechanism 10 around the centrifugal mechanism 20, the positioning mechanism 10 can be used to straighten the carrier 30 on the centrifugal mechanism 20 after the blood type analyzer 100 completes the centrifugation process of the blood type card. The structure of the positioning mechanism 10 and the straightening steps can be set with reference to the above embodiments.

[0087] Furthermore, a sample loading module is provided above the centrifugal mechanism 20, and the sample loading needle of the sample loading module can be arranged vertically relative to the carrier, so that after the carrier 30 is straightened, the sample loading needle can be directly applied to the reaction carrier in the carrier 30, thereby achieving accurate sample loading of the reaction carrier. Similarly, after the blood type analyzer 100 completes the steps of sample loading and interpretation at the centrifugal mechanism 20, the reaction carrier in the straightened carrier 30 can also be grabbed and transferred by the manipulator, thereby achieving accurate grabbing of the manipulator.

[0088] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
