Description

Technical Field

[0001] The invention relates to the technical field of blood type analyzers, and in particular to a correcting mechanism and a blood type analyzer. Background Art

[0002] In the related art, the blood type analyzer includes a centrifugal mechanism and a manipulator. Among them, a carrier is provided on the centrifugal mechanism for loading reaction carriers such as blood type cards and microplates; the centrifugal mechanism can drive the carrier and the reaction carrier inside the carrier to centrifugal motion; the manipulator can grab the reaction carrier inside the carrier from the top of the carrier. Since the carrier is prone to tilt relative to the centrifugal mechanism after centrifugal motion, the reaction carrier inside the carrier is also tilted, which will cause the manipulator to be unable to accurately grab the reaction carrier.

[0003] At present, a solution of having a built-in positioning mechanism in the manipulator is often adopted, so that before the gripping mechanism of the manipulator grabs the reaction carrier in the carrier, the positioning mechanism is used to straighten the position of the carrier from the top of the carrier, so as to facilitate the precise docking of the manipulator and the carrier. However, in this solution, due to the limited built-in space of the manipulator, the straightening angle of the positioning mechanism is generally limited to 10°, making it difficult for the positioning mechanism to achieve a good straightening effect when facing a carrier that is greatly tilted after centrifugal movement. Summary of the invention

[0004] The main purpose of the present invention is to provide a righting mechanism and a blood type analyzer, aiming to provide a righting mechanism capable of righting a carrier.

[0008] When the upright assembly is at the second position, the end surface of the upright end is horizontally extended to abut against the bottom end of the carrier so as to straighten the carrier to a horizontal state.

[0009] In one embodiment, when the alignment component is in the first position, at least a portion of the alignment end is spaced apart from the carrier in the horizontal direction and / or vertical direction so as to move from the first position toward the second position under the drive of the driving component and abut against the bottom end of the carrier.

[0010] In one embodiment, when the upright assembly is in the first position, at least a portion of the upright end is spaced apart from the carrier in the horizontal direction and in the vertical direction;

[0011] The driving component is used to drive the upright component to rotate upward from the first position in the horizontal direction toward the carrier, so that the upright component can swing forward to the second position.

[0012] In one embodiment, the drive assembly comprises:

[0013] A swing mechanism, the swing mechanism comprising a fixed seat and a first swing member, the fixed seat is arranged below the carrier, the first swing member is swingably arranged on the fixed seat and is rotatably connected to the alignment assembly; and

[0014] A driving mechanism is drivingly connected to the first swinging member and is used to drive the first swinging member to swing forward or reverse relative to the fixing seat, so as to drive the alignment component to swing toward or away from the bottom end of the carrier.

[0015] In one embodiment, the first swinging member comprises:

[0016] A rotating part, wherein the rotating part and the fixing seat are hingedly matched;

[0017] a first swinging portion, the first swinging portion being connected to one end of the rotating portion and being drivingly connected to the driving mechanism, and being configured to be swingably arranged around the rotating portion under the driving of the driving mechanism; and

[0018] The second swing part is connected to one end of the rotating part away from the first swing part and is rotationally connected to the alignment component. The second swing part is used to drive the alignment mechanism to swing synchronously along the same rotation direction when the first swing part rotates around the rotating part.

[0019] In one embodiment, the second swinging portion is provided with a connecting groove, and the connecting groove is extended along the length direction of the second swinging portion, and the driving mechanism includes:

[0020] A rotating seat, wherein the rotating seat and the second swinging member are arranged opposite to each other, and a transmission shaft is provided on a side of the rotating seat facing the second swinging member, and the transmission shaft is movably arranged in the connecting groove and slidably cooperates with the connecting groove; and

[0021] A driving member having a driving shaft, the driving shaft is transmission-connected to the rotating seat and eccentrically arranged with the transmission shaft, and the driving shaft is used to drive the rotating seat to rotate around its axial direction to drive the transmission shaft to rotate around the axial direction of the driving shaft.

[0022] In one embodiment, the driving assembly further comprises a second swinging member, two ends of which are rotatably connected to the fixing seat and the alignment assembly respectively, and the second swinging member is arranged parallel to the second swinging portion.

[0023] In one embodiment, the positioning mechanism further includes a detection component for detecting whether the positioning component moves to the first position and / or the second position.

[0028] The alignment mechanism of the technical solution of the present invention includes a driving component and an alignment component, and the driving component can drive the alignment component to switch between a first position and a second position.

[0041] 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.

[0042] 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.

[0043] 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.

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.

[0044] In the related art, the blood type analyzer includes a centrifugal mechanism and a manipulator. Among them, a carrier is provided on the centrifugal mechanism for loading reaction carriers such as blood type cards and microplates; the centrifugal mechanism can drive the carrier and the reaction carrier inside the carrier to centrifugal motion; the manipulator can grab the reaction carrier inside the carrier from the top of the carrier. Since the carrier is prone to tilt relative to the centrifugal mechanism after centrifugal motion, the reaction carrier inside the carrier is also tilted, which will cause the manipulator to be unable to accurately grab the reaction carrier.

[0045] At present, a solution of having a built-in positioning mechanism in the manipulator is often adopted, so that before the gripping mechanism of the manipulator grabs the reaction carrier in the carrier, the positioning mechanism is used to straighten the position of the carrier from the top of the carrier, so as to facilitate the precise docking of the manipulator and the carrier. However, in this solution, due to the limited built-in space of the manipulator, the straightening angle of the positioning mechanism is generally limited to 10°, making it difficult for the positioning mechanism to achieve a good straightening effect when facing a carrier that is greatly tilted after centrifugal movement.

[0046] The present invention provides a positioning mechanism 100 applied to a blood type analyzer 1000 for positioning a carrier 200 .

[0047] The carrier 200 may be configured as a blood type card carrier, wherein the carrier 200 has a top-opening accommodation space for loading blood type cards. In some embodiments, the carrier 200 may also be used to load microplates, etc., which is not limited here.

[0048] See also Figures 1 to 3In one embodiment of the present invention, the positioning mechanism 100 includes:

[0049] A positioning assembly 110, which is disposed below the carrier 200 and has a movably disposed positioning end 111; and

[0050] A driving assembly 120, wherein the driving assembly 120 is in driving connection with the alignment assembly 110, so that the alignment assembly 110 has a first position spaced apart from the carrier 200 and a second position abutting against the carrier 200;

[0051] When the alignment component 110 is at the second position, the end surface of the alignment end 111 is extended horizontally to abut against the bottom end of the carrier 200 so as to adjust the carrier 200 to a horizontal state.

[0052] When the alignment component 110 is in the first position, the alignment end 111 thereof can be spaced apart from the bottom of the carrier 200 , thereby preventing the alignment component 110 from interfering with the movement of the carrier 200 , so that the carrier 200 can perform centrifugal movement driven by the centrifugal mechanism 300 .

[0053] In an embodiment of the present invention, when the alignment component 110 is in the first position, at least a portion of the alignment end 111 is spaced apart from the carrier 200 in the horizontal direction and / or vertical direction so as to move from the first position toward the second position under the drive of the driving component 120 and abut against the bottom end of the carrier 200.

[0054] It should be noted that, in one embodiment, the upright end 111 of the upright component 110 may be spaced apart from the carrier 200 only in the horizontal direction; in another embodiment, the upright end 111 of the upright component 110 may be spaced apart from the carrier 200 only in the vertical direction; in yet another embodiment, the upright end 111 of the upright component 110 may be spaced apart from the carrier 200 in both the horizontal and vertical directions. The aforementioned embodiments can all prevent the upright end 111 located at the first position from interfering with the movement of the carrier 200, and the specific embodiments can be set according to actual needs and are not limited here.

[0055] Furthermore, when the alignment component 110 moves from the first position toward the second position, its alignment end 111 can be displaced upward to abut against the bottom of the carrier 200; when the alignment component 110 is fully moved into position, the bottom end surface of the carrier 200 can fit with the end surface of the alignment end 111, and at this time both are extended horizontally, thereby completing the alignment of the carrier 200, so that the carrier 200 cannot tilt or sway under the limitation of the alignment component 110.

[0056] Among them, the alignment component 110 can be set as an alignment socket, with an alignment end 111 formed on its top, and the end face shape of the alignment end 111 can be configured to imitate the bottom end shape of the carrier 200, so that the two can form a good fit when they abut, which is beneficial to ensure the alignment effect of the alignment mechanism 100.

[0057] In some embodiments, the drive component 120 may be configured as a linear drive mechanism, such as a screw drive mechanism 122, a telescopic cylinder, etc., which drives the alignment component 110 to reciprocate in the vertical direction to achieve the switching movement of the alignment component 110 between its first position and the second position; or, the drive component 120 may be configured as a rotational drive mechanism. For example, the alignment component 110 may be driven to rotate around the horizontal direction so that the alignment component 110 has active travels in both the vertical and horizontal directions, thereby utilizing its active travel in the vertical direction to achieve the switching movement of the alignment component 110 between its first position and the second position.

[0058] Of course, the technical solution of the present invention is not limited thereto. In some embodiments, the driving assembly 120 may be configured to include a variety of driving mechanisms, and the various driving mechanisms may be configured as the linear driving mechanisms or the rotational driving mechanisms in the aforementioned embodiments, so that the alignment assembly 110 can rotate or translate along multiple axis directions, thereby improving the degree of freedom of the alignment assembly 110. The specific implementation method may be set according to actual needs and is not limited here.

[0059] It can be understood that, compared with the technical solution of building the righting mechanism 100 inside the manipulator, the technical solution of the present invention can reuse the bottom space of the carrier 200 to set the righting mechanism 100, so that the setting of the righting mechanism 100 will not be limited by the built-in space of the manipulator, thereby having a larger righting angle range, and can be suitable for righting the carrier 200 that has tilted significantly after centrifugal movement, which is beneficial to improving the applicability of the righting mechanism 100.

[0060] Furthermore, since the positioning mechanism 100 of the present invention controls the positioning component 110 to accurately move to the second position by the driving component 120 during the righting operation, each time the righting component 110 moves to the second position, the position of the righting end 111 thereof is relatively fixed relative to the blood type analyzer 1000, thereby ensuring that the carrier 200 can be righted to the same horizontal state each time, thereby facilitating the consistency of the righting effect of the carrier 200 of the positioning mechanism 100 of the present invention.

[0061] See also Figures 1 to 3In an embodiment of the present invention, when the upright component 110 is in the first position, at least a portion of the upright end 111 is spaced apart from the carrier 200 in the horizontal direction and in the vertical direction;

[0062] The driving assembly 120 is used to drive the alignment assembly 110 to rotate upward from the first position in a horizontal direction toward the carrier 200 , so that the alignment assembly 110 can swing forward to the second position.

[0063] It is understandable that by moving the righting component 110 from the first position to the second position by means of a rotational motion, the moving path of the righting component 110 can be arranged in an arc shape. In this way, the righting end 111 of the righting component 110 can be conveniently abutted against the bottom of the carrier 200 in a tilted state during righting, thereby achieving a better righting effect.

[0064] See also Figures 1 to 3 In an embodiment of the present invention, the driving assembly 120 includes:

[0065] A swing mechanism 121, the swing mechanism 121 comprising a fixed seat 1211 and a first swing member 1212, the fixed seat 1211 is disposed below the carrier 200, the first swing member 1212 is swingably disposed on the fixed seat 1211 and is rotatably connected to the alignment assembly 110; and

[0066] The driving mechanism 122 is drivingly connected to the first swinging member 1212 and is used to drive the first swinging member 1212 to swing forward or reverse relative to the fixing seat 1211 to drive the alignment component 110 to swing toward or away from the bottom end of the carrier 200.

[0067] The first swinging member 1212 may be swingably disposed on one side of the fixed seat 1211. Specifically, in a feasible implementation, the swinging mechanism 121 further includes a fastener and a bearing, the fastener is sequentially disposed through the fixed seat 1211 and the first swinging member 1212 to connect the two, and the bearing is sleeved on the fastener to enable the two to rotate relative to each other.

[0068] On this basis, the driving mechanism 122 can be connected to any position of the first swinging member 1212 in a transmission manner to drive the first swinging member 1212 to swing forward or backward. For example, in some embodiments, the driving mechanism 122 can be directly connected to the rotation center of the first swinging member 1212 through the driving shaft 1222a, and the driving shaft 1222a is used to rotate forward or reverse along its axial direction to drive the first swinging member 1212 to swing forward or backward around the driving shaft 1222a. In other embodiments, the driving mechanism 122 can also be movably connected to a position other than the rotation center of the first swinging member 1212. For example, a connecting groove 1212d can be set on the first swinging member 1212 as in the embodiments described later, and a transmission shaft 1221a that can rotate in the same circumferential direction can be set on the driving mechanism 122. Through the cooperation of the transmission shaft 1221a and the connecting groove 1212d, the first swinging member 1212 is driven to swing forward or backward around the driving shaft 1222a. The specific implementation method can be configured according to actual needs and is not limited here.

[0069] See also Figure 3 In an embodiment of the present invention, the first swinging member 1212 comprises:

[0070] A rotating portion 1212a, wherein the rotating portion 1212a and the fixing seat 1211 are hingedly matched;

[0071] a first swinging portion 1212b, the first swinging portion 1212b being connected to one end of the rotating portion 1212a and being drivingly connected to the driving mechanism 122, and being configured to be swingably disposed around the rotating portion 1212a under the driving of the driving mechanism 122; and

[0072] The second swinging portion 1212c is connected to one end of the rotating portion 1212a away from the first swinging portion 1212b, and is rotationally connected to the alignment component 110. The second swinging portion 1212c is used to drive the alignment mechanism 100 to swing synchronously along the same rotation direction when the first swinging portion 1212b rotates around the rotating portion 1212a.

[0073] In this way, a structure similar to a lever can be formed by sequentially connecting the first swinging part 1212b, the rotating part 1212a, and the second swinging part 1212c. The rotating part 1212a can be regarded as the fulcrum of the lever structure, and the first swinging part 1212b and the second swinging part 1212c can rotate synchronously and in the same direction around the fulcrum. In this way, the first swinging part 1212b can be driven to swing forward or backward by the driving mechanism 122, and the second swinging part 1212c can be driven to swing forward or backward synchronously, and then the second swinging part 1212c can drive the correcting component 110 to move.

[0074] Furthermore, in the embodiment of the present invention, the first swinging part 1212b and the second swinging part 1212c are arranged at an angle, and the angle can be set to an obtuse angle. Such an arrangement is conducive to compactly arranging various parts of the first swinging member 1212.

[0075] See also Figure 3 In an embodiment of the present invention, the second swing portion 1212c is provided with a connecting groove 1212d, and the connecting groove 1212d is extended along the length direction of the second swing portion 1212c. The driving mechanism 122 includes:

[0076] A rotating seat 1221, wherein the rotating seat 1221 and the second swinging member 1213 are arranged opposite to each other, and a transmission shaft 1221a is provided on a side of the rotating seat 1221 facing the second swinging member 1213, and the transmission shaft 1221a is movably passed through the connecting groove 1212d and slidably matched with the connecting groove 1212d; and

[0077] The driving member 1222 has a driving shaft 1222a, the driving shaft 1222a is transmission-connected to the rotating seat 1221, and is eccentrically arranged with the transmission shaft 1221a, and the driving shaft 1222a is used to drive the rotating seat 1221 to rotate around its axial direction to drive the transmission shaft 1221a to rotate around the axial direction of the driving shaft 1222a.

[0078] The driving member 1222 may be configured as a rotary motor, and its driving shaft 1222a may be configured to extend in the horizontal direction. By eccentrically arranging the driving shaft 1222a and the transmission shaft 1221a, when the driving shaft 1222a rotates along its axial direction, the transmission shaft 1221a may perform a circular motion around the axial direction of the driving shaft 1222a, so that the transmission shaft 1221a may simultaneously have a horizontal displacement and a vertical displacement during rotation.

[0079] When the transmission shaft 1221a makes a circular motion around the axial direction of the driving shaft 1222a, it can slide relative to the extension direction of the connecting groove 1212d, and drive the second swinging part 1212c to rotate around the rotating part 1212a by pushing the groove wall of the connecting groove 1212d, so as to realize the driving connection between the driving mechanism 122 and the swinging mechanism 121.

[0080] See also Figures 1 to 3 In an embodiment of the present invention, the swing mechanism 121 also includes a second swing member 1213, both ends of which are rotatably connected to the fixed seat 1211 and the alignment component 110 respectively, and the second swing member 1213 is arranged parallel to the second swing portion 1212c.

[0081] The second swinging portion 1212c of the first swinging member 1212, the second swinging member 1213, the bottom edge of the alignment component 110, and the top edge of the fixing seat 1211 can enclose a parallelogram structure. In this way, the first swinging member 1212 and the second swinging member 1213 can realize two-point support for the alignment component 110, which is conducive to improving the movement stability of the alignment component 110.

[0082] See also Figures 1 to 3 In an embodiment of the present invention, the alignment mechanism 100 further includes a detection component for detecting whether the alignment component 110 moves to the first position and / or the second position.

[0083] The detection component can detect whether the alignment component 110 has moved into position by means of contact detection. For example, the detection component can be set as a photoelectric detection component. Specifically, the photoelectric detection component can include a sensing switch 131 and a sensing member 132. The sensing member 132 can be connected to the alignment component 110 to rotate synchronously with the alignment component 110. The sensing end of the sensing switch 131 is located on the moving path of the sensing member 132. When the alignment component 110 moves into position, the sensing member 132 on the alignment component 110 can approach the sensing switch 131 and trigger the sensing switch 131. At this time, the detection signal of the sensing switch 131 can be used to judge that the alignment component 110 has moved to the corresponding position.

[0084] Of course, the technical solution of the present invention is not limited to this. In some embodiments, the detection component can also detect whether the positioning component 110 has moved into place by non-contact detection. For example, a pressure sensor can be set corresponding to the positioning component 110 located at the first position and / or the second position. When the positioning component 110 moves into place, its outer wall can abut against the pressure sensor. At this time, the detection signal of the pressure sensor can be used to judge that the positioning component 110 has moved to the corresponding position.

[0085] Further, there may be only one detection component, which may be a first detection component for detecting whether the alignment component 110 moves to the first position, or a second detection component for detecting whether the alignment component 110 moves to the second position. There may also be at least two detection components, the at least two detection components including a first detection component for detecting whether the alignment component 110 moves to the first position and a second detection component for detecting whether the alignment component 110 moves to the second position, for respectively detecting whether the alignment component 110 moves to the first position and the second position.

[0086] See also Figures 1 to 3 In an embodiment of the present invention, the positive end 111 is provided with a groove 1111 .

[0087] The groove 1111 is extended along the length direction of the alignment component 110, and both ends of the groove 1111 can be through-set. It is understandable that by providing the groove 1111, the alignment end 111 of the alignment component 110 and the bottom end of the carrier 200 can be easily engaged with each other to ensure the alignment effect of the alignment mechanism 100.

[0088] Furthermore, in some embodiments, the notch of the groove 1111 is further provided with a guide structure, which includes two guide walls 1111a arranged opposite to each other, the distance between the two guide walls 1111a gradually increases in the direction away from the groove 1111, and the guide wall 1111a can be arranged as a plane or an arc surface. In this way, through the guiding effect of the guide structure, the alignment end 111 of the alignment component 110 and the bottom end of the carrier 200 can be easily docked with each other for clip-fitting.

[0089] See also Figures 4 to 6 The present invention further proposes a blood type analyzer 1000, which includes a carrier 200 and a positioning mechanism 100. The specific structure of the positioning mechanism 100 refers to the above embodiment. Since the blood type analyzer 1000 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.

[0090] See also Figures 1 to 6 In an embodiment of the present invention, the blood type analyzer 1000 further includes a centrifugal mechanism 300, and the alignment mechanism 100 is located at the bottom side of the centrifugal mechanism 300;

[0091] The centrifugal mechanism 300 is provided with a plurality of the carriers 200 along the same circumferential direction. The centrifugal mechanism 300 is used to drive the carriers 200 to perform centrifugal motion around the vertical direction and to drive the carriers 200 to approach the alignment mechanism 100 so as to be arranged opposite to the alignment mechanism 100 along the vertical direction.

[0092] In a feasible embodiment, the blood type analyzer 1000 can be configured as a large blood type analyzer 1000, and has separately arranged centrifugal mechanism 300, interpretation mechanism and other mechanisms. After the centrifugal mechanism 300 of the blood type analyzer 1000 completes the centrifugation of the reaction carrier, the reaction carrier in the carrier 200 can be grabbed by a manipulator above the centrifugal mechanism 300 and transferred to the interpretation mechanism of the blood type analyzer 1000 for subsequent interpretation.

[0093] The blood type analyzer 1000 further includes a body, in which an installation space is formed, and the centrifugal mechanism 300 and the alignment mechanism 100 can be accommodated inside the installation space. The centrifugal mechanism 300 can be specifically configured as a centrifugal turntable, and a plurality of carriers 200 can be rotatably arranged on the circumference of the centrifugal turntable in a mounting manner, but not limited to, and the reaction carrier can be loaded through the carrier 200. The reaction carrier can be configured as a blood type card, a blood type plate, etc., which is not limited here.

[0094] In some embodiments, the installation space has an opening that can be opened and closed, and the robot can be configured outside the installation space and can enter and exit the installation space through the opening to grab and transfer the reaction carrier in the installation space.

[0095] Furthermore, the alignment mechanism 100 is disposed at the bottom side of the centrifugal mechanism 300, and the alignment end 111 of the alignment mechanism 100 is movably disposed in the vertical direction and has a first position and a second position in its movable range, and the first position is disposed away from the centrifugal mechanism 300, and the second position is disposed close to the carrier 200 of the centrifugal mechanism 300. Before the centrifugal mechanism 300 drives the carrier 200 to move centrifugally, the alignment end 111 of the alignment mechanism 100 can be as follows: Figure 2 or Figure 5 As shown, it moves to the first position to avoid interference with the centrifugal mechanism 300 and the carrier 200 which are in motion.

[0096] After the centrifugation process of the reaction carrier is completed, the centrifugal mechanism 300 can also make the carrier 200 approach the positioning mechanism 100 through rotational movement, so that the carrier 200 can be arranged vertically relative to the positioning mechanism 100 after stopping the rotation. At this time, the positioning end 111 of the positioning mechanism 100 can be as shown in FIG. Figure 1 or Figure 6 As shown, it moves to the second position, so that its upright end 111 abuts against and pushes the bottom wall of the carrier 200, and straightens the carrier 200 to a horizontal state, so that the robot above the carrier 200 can accurately grasp the reaction carrier in the carrier 200, and transfer the reaction carrier to other mechanisms of the blood type analyzer 1000, such as the reading mechanism, for subsequent processing.

[0097] Furthermore, in this embodiment, the centrifugal mechanism 300 can drive several carriers 200 to approach a positioning mechanism 100 in turn, so that the positioning mechanism 100 can straighten the several carriers 200 in turn, and the reaction carriers in the straightened carriers 200 can be grabbed and transferred in turn by the robot at the top of the centrifugal mechanism 300.

[0098] Of course, the technical solution of the present invention is not limited to this. The blood type analyzer 1000 can also be provided with a plurality of alignment mechanisms 100 on the circumferential side of the centrifuge mechanism 300. The plurality of alignment mechanisms 100 are arranged in sequence along the circumference of the centrifuge mechanism 300 at intervals, and each alignment mechanism 100 is arranged corresponding to a carrier 200, so that after the centrifugation process of the blood type card is completed, the plurality of carriers 200 on the centrifuge mechanism 300 can be synchronously aligned by the plurality of alignment mechanisms 100, and the reaction carriers in the plurality of carriers 200 can be further synchronously grasped and transferred by a plurality of manipulators to improve the working efficiency of the blood type analyzer 1000, which is not limited here.

[0099] In another feasible implementation, the blood type analyzer 1000 may also adopt an integrated design, wherein the centrifugal mechanism 300 thereof is integrated with a sample loading module, a judgment module, etc., so that the carrier 200 can cooperate to complete the sample loading, judgment, etc. steps at the centrifugal mechanism 300, and then the reaction carrier that has completed the experiment in the carrier 200 is grabbed by a manipulator to be removed from the centrifugal mechanism 300 for disposal. In this embodiment, by arranging a positioning mechanism 100 on the peripheral side of the centrifugal mechanism 300, the carrier 200 on the centrifugal mechanism 300 can be straightened by the positioning mechanism 100 after the blood type analyzer 1000 completes the centrifugal process of the blood type card. The structure of the positioning mechanism 100 and the straightening steps thereof can be set with reference to the above-mentioned embodiments.

[0100] Furthermore, a sample loading module is provided above the centrifugal mechanism 300, and the sample loading needle of the sample loading module can be arranged vertically opposite to the carrier 200, so that after the carrier 200 is straightened, the sample loading needle can be directly applied to the reaction carrier in the carrier 200, thereby achieving accurate sample loading of the reaction carrier. Similarly, after the blood type analyzer 1000 completes the steps of sample loading and interpretation at the centrifugal mechanism 300, the reaction carrier in the straightened carrier 200 can also be grabbed and transferred by the manipulator, thereby achieving accurate grabbing of the manipulator.

[0101] 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.
