For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Combination Figures 1 to 3 As shown, the fully automatic blood type analyzer includes a workbench 10 and a circulation conveying component 20 installed on the workbench 10 .

[0036] The circulating conveying assembly 20 includes a ring-shaped conveying bar 21, a power device 22 and a plurality of blood type card carrying boxes 23. The power device 22 acts on the conveying bar 21 and can drive the conveying bar 21 to rotate along a ring route. The blood type card carrying boxes 23 are connected to the conveying bar and can be moved by the conveying bar.

[0037] Combination Figure 4 As shown, in a preferred embodiment, the conveying bar 21 is a conveying chain, and a plurality of vertical positioning posts 211 are provided on the conveying chain, and the blood type card carrier box 23 is provided with positioning holes 231 that cooperate with the positioning posts.

[0038] In this technical solution, the blood type card carrier box is sleeved on the positioning column along the vertical direction through the positioning hole, thereby realizing a detachable connection between the blood type card carrier box and the conveying chain.

[0039] Furthermore, the conveyor chain includes a plurality of chain links connected in series, and adjacent chain links are rotatably connected by connecting pins, and the connecting pins are vertically arranged. Part of the connecting pins protrude upward to form the positioning column 211.

[0040] It should be noted that, except for the connecting pins used to connect to the blood type card carrier box, other connecting pins should not protrude from the top surface of the chain link or protrude less to avoid the connecting pins affecting the installation of the blood type card carrier box.

[0041] In another embodiment, the conveying strip 21 may also be a conveyor belt, and the blood type card carrier boxes 23 are supported on the conveyor belt surface in an annular array. In order to position the blood type card carrier boxes 23, the conveyor belt may be provided with a limit block (blocking the side of the blood type card carrier box), a limit groove (the bottom of the blood type card carrier box is accommodated in the limit groove), or a boss (the blood type card carrier box is provided with a plug hole to cooperate with the boss) to limit the carrier box.

[0042] Combination Figure 3As shown, in one embodiment, the power device 22 includes a motor 221, a first gear 222, a second gear 223, a first synchronous pulley 224 and a second synchronous pulley 225. The two ends of the conveyor bar 21 are respectively meshed with the first gear 222 and the second gear 223 for transmission. The first synchronous pulley 224 is fixed to the end of the rotating shaft of the motor 221, and the second synchronous pulley 225 is fixed to the second gear 222 through a rotating shaft 226. The first synchronous pulley 224 and the second synchronous pulley 225 are connected by a synchronous belt 227.

[0043] Furthermore, the second synchronous pulley 225 is disposed directly below the second gear 223 , and the rotating shaft 226 is vertically disposed and fixed to the axis of the second synchronous pulley and the second gear respectively.

[0044] The first gear 222 and the second gear 223 are located in the same horizontal plane to ensure the transmission of the conveying strip in the horizontal direction.

[0045] The first synchronous pulley 224 and the second synchronous pulley 225 are located in the same horizontal plane. In a preferred embodiment, the outer diameter of the first synchronous pulley 224 is smaller than that of the second synchronous pulley 225 , and the motor is disposed directly below the first synchronous pulley 224 .

[0046] In this technical solution, the first synchronous pulley, the second synchronous pulley and the motor are arranged as a whole below the conveyor bar without interfering with the working space above the conveyor bar.

[0047] When working, the motor rotates to transfer power from the first synchronous pulley to the second synchronous pulley. The speed is controlled by the transmission ratio of the first synchronous pulley and the second synchronous pulley. The second synchronous pulley further drives the second gear to rotate through the rotating shaft. The second gear engages with the conveyor bar, thereby driving the conveyor bar to move in a circle. The conveyor bar pulls the blood type card carrier box to move in a circle through the positioning column.

[0048] Combination Figure 2 As shown, the workbench 10 includes a horizontally arranged workbench plate 11, on which a positioning column window 111 is opened, and the top of the positioning column 211 protrudes from the upper surface of the workbench plate 11 through the positioning column window 111, and the conveying bar 21 and the power device 22 are located below the workbench plate 11.

[0049] In one embodiment, the moving route of the conveying bar 21 is annular, and an elliptical partition 228 is set between the conveying bars 21. The partition 228 is located in the positioning column window 111 and forms an annular channel with the positioning column window 111. The positioning column 211 moves cyclically along the channel.

[0050] Furthermore, the partition 228 and the workbench 11 are located in the same plane.

[0051] In this technical solution, the conveyor bar and the power device are located as a whole under the work table, and only the positioning column protrudes above the work table, which can protect the conveyor bar, etc. and greatly improve the safety factor. The overall structure is simple and compact.

[0052] Combination Figure 4 As shown, the positioning hole 231 is formed on one side of the blood type card carrying box 23 .

[0053] In this technical solution, when the conveying bar pulls the blood type card carrier box to move, the blood type card carrier box is located at the periphery of the positioning column window 111. In this way, more blood type card carrier boxes can be discharged at the same time.

[0054] Furthermore, the blood type card carrying box 23 is supported on the workbench 11 , and a roller 232 is rotatably provided at the bottom of the blood type card carrying box 23 .

[0055] In this technical solution, the conveying bar 21 provides dragging power for the blood type card carrier box through the positioning column 211, and the blood type card carrier box 23 slides around the positioning column window 111 through rollers.

[0056] In one embodiment, the blood type card carrying box 23 includes a box body 233 , a bottom plate 234 and a trolley 235 .

[0057] The box body 233 is provided with a plurality of strip-shaped grooves 2331 for inserting the blood supply type cards 30 .

[0058] The bottom plate 234 covers the bottom opening of the box body 233 and is detachably connected to the box body 233 .

[0059] The base plate 234 and the trolley 235 are detachably connected. In one embodiment, the base plate 234 and the trolley are fixed by screws 236 .

[0060] The rollers 232 and the positioning holes 231 are both formed on the trolley, and the trolley serves as a transportation device and can slide on the workbench 11 .

[0061] Combination Figure 1 As shown, the workbench 10 also includes a frame 12 , and the workbench plate 11 is installed on the frame 12 .

[0062] The frame 12 is also equipped with a puncturing device 40 , a sample adding device 50 , a manipulator 60 , a centrifugal mechanism 70 and a blood type card reading mechanism 80 .

[0063] The piercing device 40 , the sample adding device 50 , and the manipulator 60 are sequentially arranged at different positions on the moving route of the blood type card carrier box 23 .

[0064] The puncturing device 40 and the sample adding device 50 are arranged above the circulation conveying assembly 20. The puncturing device 40 is used to puncture and punch the blood type card 30 placed in the blood type card carrier box 23; the sample adding device 50 is used to add blood samples and reagents into the blood type card 30.

[0065] The working sequence of the fully automatic blood type analyzer in this case is:

[0066] (1) The conveying bar 21 pulls the blood type card carrying boxes 23 containing the blood type cards 30 to move in a circular manner;

[0067] (2) The puncturing device 40 sequentially punctures and punches holes in the blood type card 30 in the blood type card carrier box 23;

[0068] (3) The sample adding device 50 draws blood samples and reagents from the sample placement area and the reagent placement area respectively, and then adds the blood samples and reagents into the punctured blood typing card 30;

[0069] (4) After the filling is completed, the robot picks up the blood type cards one by one and transfers them to the centrifuge;

[0070] (5) After centrifugation is completed, the robot further transfers the centrifuged blood type card to the blood type card reading mechanism 80, and the blood type card reading mechanism 80 performs image recognition.

[0071] In this case, since multiple blood type card carriers 23 move cyclically, puncturing, adding samples and picking up by the robot can be operated independently without affecting each other. Specifically, when the puncturing device punctures the blood type card in one of the blood type card carriers, the adding sample device can simultaneously add blood type cards in the adjacent blood type card carrier that have completed the puncture operation. At the same time, the robot can synchronously transfer the blood type cards that have completed the adding sample to the centrifuge. This case has obvious advantages in work efficiency.

[0072] In one embodiment, the workbench 11 is also provided with a sample barcode reader, a reagent placement area, a sample placement area for placing blood samples, a dilution plate placement area, etc. These structures can adopt the common structures and principles in the prior art and will not be repeated in this case.

[0073] In addition, the puncturing device 40, the sample adding device 50, the centrifugal mechanism 70 and the blood type card reading mechanism 80 can also adopt the common structures and principles in the prior art, which will not be described in detail in this case.

[0074] It should be noted that the centrifugal mechanism 70 is installed below the workbench 11 to meet the requirements of safety and space. A window connected to the centrifugal mechanism is provided on the workbench to facilitate the operation of the manipulator.

[0075] Combination Figure 5a and Figure 5b As shown, the manipulator 60 includes a blood type card picking device 61, which can be moved between the centrifugal mechanism 70 and the circulating conveying component 20 in the horizontal direction and can be moved in the vertical direction.

[0076] Combination Figure 6 As shown, the blood type card picking device 61 includes a bracket 611, and at least one group of grippers 612 and a power device 613 installed on the bracket.

[0077] Each group of grippers 612 includes two hooks arranged opposite to each other, and a bite opening is formed between the bottom ends of the two hooks, and the bite opening corresponds to the long edge of the top end of the blood type card.

[0078] The power device 613 acts on the hook body and controls the size of the bite opening.

[0079] During operation, the power device acts on the two hooks of each group of grippers, so that the openings at the bottom ends of the two hooks reach the maximum. When the blood type card is located in the bite mouth, the power device acts on the grippers, so that the two opposite hooks are close to each other, and the bottom ends of the hooks protrude under the two long edges of the top of the blood type card, respectively, to pick up the blood type card in the vertical direction.

[0080] Furthermore, a driving rod 617 and a supporting rod 614 are also provided on the bracket 611. The power device is connected to the driving rod 617 and can drive the driving rod 617 to approach or move away from the supporting rod 614. The hook body is rotatably connected to the supporting rod 614. A connecting rod 615 is also provided between each hook body and the driving rod 617. The two ends of the connecting rod 615 are respectively rotatably connected to the driving rod 617 and the top end of the hook body.

[0081] In one embodiment, the driving rod 617 and the supporting rod 614 are arranged in parallel, and the driving rod 617 is located above the supporting rod 614 .

[0082] This case is based on the lever principle. When the driving rod 617 moves away from the support rod 614, the connecting rod 615 drives the hook body to rotate outward, driving the bite opening to increase; when the driving rod 617 approaches the support rod 614, the connecting rod 615 pushes the hook body to rotate inward, driving the bite opening to decrease.

[0083] In a preferred embodiment, two groups of grippers 612 may be provided along the length direction of the blood type card to ensure that the blood type card picking process maintains a certain stability without shaking.

[0084] In this technical solution, two groups of grippers are arranged in parallel along the length direction of the support rod, which can ensure that all grippers work synchronously.

[0085] In another embodiment, a group of grippers may also be provided. To ensure the stability of the grippers in grasping the blood type card, the width of the hook body may be set longer, for example, slightly less than or equal to the length of the blood type card, so that most or all of the long edges of the blood type card interact with the hook body.

[0086] Furthermore, the power device 613 is a telescopic cylinder.

[0087] The telescopic cylinder may be a telescopic air cylinder, a telescopic electric cylinder or a hydraulic cylinder.

[0088] In another embodiment, the power device 613 may also be a motor and a screw rotating shaft thereof, and the screw and the driving rod are threadedly matched.

[0089] Furthermore, the bracket 611 is a U-shaped bracket with an opening facing downward, two ends of the support rod 614 are respectively connected to two extension arms of the U-shaped bracket, and the power device is installed on the top of the U-shaped bracket.

[0090] In this technical solution, the driving rod 617, the supporting rod 614 and the connecting rod 615 are protected in the space surrounded by the U-shaped bracket, and the engaging opening protrudes below the U-shaped bracket. The overall structure is compact and has a high safety factor.

[0091] Furthermore, a guide rod 616 is provided between the driving rod 617 and the supporting rod 614 .

[0092] Preferably, two guide rods are provided, and the guide rods guide the driving rods so that the guide rods move in a specific direction.

[0093] Combination Figure 5a and Figure 5b As shown, the manipulator 60 also includes a two-axis moving mechanism that can realize horizontal and vertical movement, and the blood type card picking device 63 is arranged on the two-axis moving mechanism.

[0094] The two-axis moving mechanism includes a horizontal beam 62 and a vertical beam 63. The horizontal beam 62 is installed on the frame 12 and is arranged between the centrifugal mechanism 70 and the circulating conveying component 20. The vertical beam 63 is connected to the horizontal beam 62 and can move in the horizontal direction along the horizontal beam 62. The blood type card picking device 61 is arranged on the vertical beam 63 and can move in the vertical direction relative to the vertical beam 63.

[0095] On the whole, the blood type card picking device can realize three-axis motion, including horizontal and vertical movement, and the grabbing motion of the gripper.

[0096] Furthermore, the cross beam 62 is provided with a first motor 621, a synchronous belt 622 with a rack, and two synchronous pulleys 623 meshing with the synchronous belt 622. The first motor 621 is connected to a synchronous pulley 623, the synchronous belt 622 is arranged in a horizontal direction, and the vertical beam 63 is connected to the synchronous belt 622.

[0097] During operation, the first motor 621 acts on a synchronous pulley and can drive the synchronous pulley to rotate. The synchronous pulley meshes with the synchronous belt 622 and can drive the synchronous belt 622 to rotate. The synchronous belt 622 then drives the vertical beam 63 to move in the horizontal direction along the horizontal linear guide rail 624.

[0098] Furthermore, a second motor 631, a synchronous belt 632 with a rack, and two synchronous pulleys 633 meshing with the synchronous belt 632 are provided on the vertical beam 63. The second motor 631 is connected to a synchronous pulley 633. The synchronous belt 632 is arranged along the vertical direction, and the blood type card picking device 61 is connected to the synchronous belt 632.

[0099] During operation, the second motor 631 acts on a synchronous pulley and can drive the synchronous pulley to rotate. The synchronous pulley meshes with the synchronous belt 632 and can drive the synchronous belt 632 to rotate. The synchronous belt 632 then drives the blood type card picking device 61 to move in the vertical direction along the vertical linear guide rail 634.

[0100] In summary, the advantages of the fully automatic blood type analyzer in this case include at least:

[0101] (1) By setting up a circulating conveying component, multiple blood type card carrier boxes are circulated and moved, and puncturing, adding samples and picking up by a robot can be performed independently without affecting each other. The overall structure is compact and the volume is small, and the work efficiency is greatly improved.

[0102] (2) The robot picks up the long edge of the blood type card based on the lever principle, with high picking success rate and high stability.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
