[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 embodiments described 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 making creative efforts shall fall 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 indications 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 for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. 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 mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] In related technologies, blood typing analyzers include a centrifuge and a carrier mounted on the centrifuge. The carrier can be used to hold reaction carriers such as blood typing cards and microplates. The centrifuge drives the carrier and the reaction carriers within it into centrifugal motion. The blood typing analyzer can also use a robotic arm to grab and transfer the reaction carriers within the carrier.

[0037] Since the carrier is prone to tilt relative to the centrifugal mechanism after centrifugal movement, 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, thereby affecting 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 typing card carrier, having an internal travel space with an open top for loading blood typing cards. In some embodiments, the carrier can also be used to load microplates, etc., without limitation.

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

[0040] a righting lever 11 having a righting end 111; and

[0041] a drive assembly 12, the drive assembly 12 being drivingly connected to the righting lever 11 so that the righting lever 11 has a first position spaced apart from the carrier 30 and a second position abutting the carrier 30;

[0042] When the alignment lever 11 is in the second position, the end surface of the alignment end 111 is vertically arranged to abut against 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 that is 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, it can drive the side face of the carrier 30 abutting therewith to also be arranged in a vertical plane, 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 conducive to ensuring the consistency of the righting effect of the carrier 30 of the positioning mechanism 10 of the present invention.

[0045] The righting lever 11 may be a rod structure extending in a straight line, with its side or end forming a righting end 111 for contacting the carrier 30. The righting lever 11 may also be configured as a block or other shape, which is not limited here. To ensure the righting effect of the righting lever 11, the dimensions of its righting end 111 may be close to or larger than the side dimensions of the carrier 30, so that the two can fully contact each other when contact occurs; furthermore, the shape of its righting end 111 may be configured to mimic the shape of the side of the carrier 30, so that the two can form a good fit when contact occurs.

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

[0047] a connecting member 121 connected to one end of the righting lever 11 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 shift lever 11 to switch between the first position and the second position.

[0049] In which, the driving member 122 can be configured as a rotational driving mechanism, which drives the connecting member 121 to rotate through the driving member 122 to drive 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 to this. In some embodiments, the driving member 122 can also be configured as a linear driving mechanism such as a screw driving mechanism, a telescopic cylinder, etc., and the driving member 122 drives the connecting member 121 to reciprocate in a linear direction, thereby driving the righting lever 11 to move linearly toward or away from the carrier 30, thereby realizing the switching movement of the righting lever 11 between its first position and the second position; alternatively, the driving assembly 12 can also include multiple driving members 122, and the multiple driving members 122 include the linear driving mechanism or the rotational driving mechanism in the aforementioned embodiment, so that the righting lever 11 can rotate or translate along multiple axes to increase the degree of freedom of the righting 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 includes 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 drive 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 set as a rotating motor, and the driving shaft of the rotating motor extends in the vertical direction and is driven and connected to the connecting member 121, so that the connecting member 121 can be rotatable 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 when rotating, 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 surface of the carrier 30, or, the positioning lever 11 can move away from the carrier 30 in the horizontal direction to the first position when rotating, for avoiding the carrier 30.

[0054] Furthermore, 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.

[0055] Specifically, a central hole is provided in the connecting member 121 for receiving the drive shaft. The centering lever 11 is located around the connecting member 121, spaced relative to the center of the connecting member 121. This allows the centering lever 11 to be positioned eccentrically relative to the drive shaft. This ensures that the centering lever 11 is displaced horizontally when the drive shaft rotates about its axial direction.

[0056] Furthermore, in some embodiments, the connecting member 121 can be configured as a rotationally symmetrical shape, such as a circle or an ellipse, with the drive shaft located at its rotation center. This configuration allows the connecting member 121 to rotate about its rotation center, and when the connecting member 121 rotates a certain angle about its rotation center and changes to another orientation, its outline can match its outline in the previous orientation. This helps reduce the rotation space required for the connecting member 121.

[0057] Of course, the technical solution of the present invention is not limited to this. In some embodiments, the central axis of the connecting member 121 and the central axis of the righting lever 11 can be eccentric relative to the drive shaft. In this way, when the drive shaft rotates about its axis, the righting lever 11 can be ensured to move horizontally. The specific implementation method can be customized 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 configured as an arc. It is understood that by providing the alignment end 111 of the alignment lever 11 with a certain curvature, the alignment lever 11 is facilitated to smoothly abut against the side of the carrier 30 through the alignment end 111, thereby preventing the risk of a significant collision between the two during the alignment process.

[0059] See also Figure 2 In an embodiment of the present utility model, the positioning mechanism 10 further includes a mounting bracket 123, the mounting bracket 123 having 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 communicating with 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, side plates, and a bottom plate connected in sequence to enclose a mounting space 123b for mounting the driver 122. The top plate may be provided with a clearance hole. The driver 122 may be mounted directly on the bottom side of the top plate so that its drive shaft mates with the clearance hole in the top plate and is exposed above the top plate. The driver 122 may also be mounted on the side plates or the bottom plate, without limitation.

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

[0063] See also Figure 2 In an embodiment of the present invention, the positioning mechanism 10 further includes an in-position detection component 13 for detecting whether the positioning 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 at both ends of the movable stroke of the positioning lever 11, and whether the positioning lever 11 has moved to the first position or the second position is detected by 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 as described in the embodiments below.

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

[0067] a sensing member 131 , the sensing member 131 being drivingly connected to the driving assembly 12 so as to rotate synchronously with the righting lever 11 under the driving of the driving assembly 12 ; and

[0068] The induction switch 132 is located on the peripheral side of the positioning 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 configured as a photoelectric barrier, and the sensing switch 132 can be configured as a photoelectric switch, wherein the photoelectric switch has a detection slot for forming its detection end. When the photoelectric barrier moves into the detection slot, the photoelectric switch is triggered, and the sensing element 131 is detected to be at the position where the photoelectric switch is located.

[0070] In some embodiments, the sensing member 131 can be directly provided on the righting lever 11 and protrude toward the side of the righting lever 11. In this way, when the driving assembly 12 drives the righting lever 11 to rotate, the righting 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 can also be directly connected to the driving assembly 12. For example, the sensing member 131 can be provided on the connecting member 121 of the driving assembly 12 in the aforementioned embodiment and spaced apart from the righting lever 11. In this way, 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 righting 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 utility model, there are two sensor switches 132, and the two sensor switches 132 are spaced apart and arranged on the circumference of the positive 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 respectively disposed opposite to the sensing ends of the two sensing switches 132 .

[0073] Specifically, the two sensing switches 132 include a first sensing switch 132a, which is configured to correspond to the sensing piece when the righting lever 11 is in the first position, and a second sensing switch 132b, which is configured to correspond to the sensing piece when the righting lever 11 is in the first position. When the first sensing switch 132a is triggered by the sensing member 131 and the second sensing switch 132b is not triggered, the detection result indicates that the righting lever 11 is in the second position. At this time, the righting lever 11 can be moved into position and the vehicle 30 can be straightened.

[0074] Similarly, when the second sensor switch 132b is triggered by the sensor element 131 and the first sensor switch 132a is not triggered, the detection result indicates that the righting lever 11 is in the first position. At this time, the centrifugal mechanism 20 of the blood type analyzer 100 can drive the carrier 30 to move, thereby preventing interference between the carrier 30 and the righting mechanism 10. This configuration can simultaneously determine the triggering status of both sensor switches 132, thereby avoiding the risk of a single failure of the righting mechanism 10.

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

[0076] See also Figures 1 to 3 In an embodiment of the present utility model, the blood type analyzer 100 further includes a centrifugal mechanism 20, and the uprighting 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, for driving the carriers 30 to rotate in the vertical direction and for driving the carriers 30 to approach the alignment mechanism 10 so as to be arranged opposite to the alignment mechanism 10 in the horizontal direction.

[0078] Specifically, the centrifugal mechanism 20 can be configured as a centrifugal turntable, and a number of carriers 30 can be, but are not limited to, rotatably arranged on the periphery of the centrifugal turntable in a mounted manner. The loading of the reaction carrier can be achieved through the carrier 30. The reaction carrier can be, but is not limited to, configured as a blood type card, a microplate, etc., 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, interpretation 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 robotic arm and transferred to the interpretation mechanism of the blood type analyzer for subsequent interpretation.

[0080] In this embodiment, the positioning mechanism 10 is arranged on the circumference of the centrifugal mechanism 20, and the positioning end 111 of the positioning mechanism 10 is movable in the horizontal direction and has a first position and a second position in 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 positioning end 111 of the positioning 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 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 positioning mechanism 10 through rotation, so that the carrier 30 can be arranged horizontally relative to the positioning mechanism 10 after stopping rotation. At this time, the positioning end 111 of the positioning 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 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 positioning mechanism 10, the positioning end 111 of the positioning mechanism 10 is also controlled to move from the first position to the second position, so that the carrier 30 and the positioning mechanism 10 can move into position at the same time or almost at the same time and cooperate with each other, which is beneficial to ensure the positioning mechanism 10 has a straightening effect 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 several carriers 30 in turn, and use the robot arm 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 positioning mechanisms 10 on the circumferential side of the centrifugal mechanism 20. The plurality of positioning mechanisms 10 are arranged in sequence along the circumference of the centrifugal mechanism 20. Each positioning 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 straightened by the plurality of positioning mechanisms 10, and the reaction carriers in the plurality of carriers 30 can be further synchronously grasped and transferred by multiple 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 interpretation module, etc., so that the carrier can cooperate with the centrifugal mechanism 20 to complete the sample loading, interpretation and other steps, and then the reaction carrier that completes the experiment in the carrier is grabbed by a robotic arm to be removed from the centrifugal mechanism for disposal.

[0086] In this embodiment, by disposing a positioning mechanism 10 around the centrifuge mechanism 20, the positioning mechanism 10 can be used to straighten the carrier 30 on the centrifuge 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 configured similarly 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. In this way, after the carrier 30 is upright, the sample loading needle can be used to directly load the reaction carrier within the carrier 30, thereby achieving precise loading of the reaction carrier. Similarly, after the blood type analyzer 100 completes the sample loading and interpretation steps at the centrifugal mechanism 20, the robot arm can also grasp and transfer the reaction carrier within the uprighted carrier 30, thereby achieving precise grasping by the robot arm.

[0088] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
