Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a disordered sample injection device and a disordered sample injection system. Background Technology

[0002] Disordered sample delivery devices are used to transport sample tubes containing samples in an unordered manner. When the unordered sample tubes exit the device, each tube must be in the correct upright position, with the tube cap directly above the tube body, so that the robotic arm can transfer the sample tubes from the device to the next processing step. However, with traditional disordered sample delivery devices, the sample tubes may be inverted or tilted when exiting, causing the tube cap to be below the tube body. This can easily lead to liquid spillage and ultimately compromise the safety of the sample delivery process. Summary of the Invention

[0003] One technical problem addressed by this application is how to improve the safety of sample tube delivery in disordered sample introduction devices.

[0010] A side-pushing mechanism is used to remove defective sample tubes from the conveying mechanism;

[0011] The rotating mechanism includes a rotating member rotatably connected to the frame and used to receive the sample tube from the conveying mechanism; and

[0012] A lifting mechanism for receiving the sample tube from the rotating mechanism.

[0013] In one embodiment, the blocking mechanism has a blocking position, the sieve tube mechanism has an input pusher, the end of the input pusher has an input pusher ramp for supporting the sample tube, the input pusher is slidably connected to the frame in the vertical direction, and the input pusher ramp is used to input the sample tube in the accommodating cavity to the blocking position.

[0014] In one embodiment, the sieve tube mechanism further includes a first fixing member and a first pushing member. The first fixing member is fixedly connected to the frame and has a first fixing inclined surface. The first pushing member is slidably connected to the frame in a vertical direction and has a first pushing inclined surface. The first fixing member is located between the input pushing member and the first pushing member. The sample tube on the first pushing inclined surface can enter the input pushing inclined surface through the first fixing inclined surface.

[0015] And / or, the screen tube mechanism further includes a blocking member located between the receiving cavity and the blocking position, the blocking member having a blocking slope.

[0016] In one embodiment, the sieve tube mechanism further includes a second fixing member and a second pushing member. The second fixing member is fixedly connected to the frame and has a second fixing inclined surface. The first fixing inclined surface is located above the second fixing inclined surface. The second pushing member is slidably connected to the frame in the vertical direction and has a second pushing inclined surface. The second fixing member is located between the first pushing member and the second pushing member. The sample tube on the second pushing inclined surface can enter the first pushing inclined surface through the second fixing inclined surface.

[0017] In one embodiment, the blocking mechanism further includes a blocking motor, a blocking cam, and a blocking shaft. The blocking motor is mounted on the frame, the blocking cam is connected to the blocking motor, the blocking shaft is mounted on the cam, and the blocking shaft and the blocking cam are not coaxial. The blocking member is provided with a guide groove and is slidably connected to the frame in the vertical direction. The blocking shaft is slidably engaged with the guide groove.

[0018] In one embodiment, the conveying mechanism has a first conveying groove and a second conveying groove, and the conveying mechanism has a conveying ramp. The first conveying groove is located between the second conveying groove and the blocking mechanism. The first conveying groove receives the sample tube from the blocking mechanism, and the second conveying groove receives the sample tube from the first conveying groove. The sample tube on the second conveying groove is conveyed to the rotating mechanism through the conveying ramp.

[0019] In one embodiment, the conveying mechanism further includes a conveying motor and a conveying component connected to each other. The conveying mechanism also has a first clearance groove and a second clearance groove. The first clearance groove is connected to the first conveying groove, and the second clearance groove is connected to the second conveying groove. The first conveying component includes a first actuating part and a second actuating part that are spaced apart. The first actuating part is movably disposed in the first clearance groove and can extend into the first conveying groove. The second actuating part is movably disposed in the second clearance groove and can extend into the second conveying groove.

[0020] In one embodiment, the side-pushing mechanism includes a side-pushing motor, a side-pushing component, a rotating component, and a receiving component. The side-pushing component is slidably connected to the frame, and the side-pushing motor drives the side-pushing component to slide.

The middle part of the gripper finger is rotatably connected to the lifting chamber. The elastic element abuts between the lifting chamber and the opening / closing cam. The opening / closing cam is slidably connected to the lifting chamber. The stop member is connected to the frame. When the stop member abuts against the lower end of the gripper finger, the upper end of the gripper finger moves away from the lifting chamber. When the stop member disengages from the lower end of the gripper finger, the elastic element pushes the opening / closing cam to abut against the lower end of the gripper finger, so that the upper end of the gripper finger moves closer to the lifting chamber.

[0023] A disordered sample injection system includes a frame, an injection drawer, and the disordered sample injection device described in any one of the above. The frame is provided with an installation cavity. The injection drawer includes a drawer body and a movable wall. The drawer body is slidably disposed within the installation cavity, forming a drawer cavity. The movable wall is movably connected to the drawer body. When the drawer body is outside the installation cavity, the movable wall blocks the drawer cavity. When the drawer body is inside the installation cavity, the movable wall opens the drawer cavity, allowing the drawer cavity to communicate with the receiving cavity.

[0024] One technical effect of one embodiment of this application is that, through the combined action of the sieve tube mechanism, blocking mechanism, conveying mechanism, side pushing mechanism, rotating mechanism and lifting mechanism, when the sample tube is finally output from the lifting mechanism, the sample tube will be set completely vertically with the tube cap facing upwards. This effectively avoids the sample tube from tilting or even turning upside down, ensuring that the sample tube is transported in the correct posture. When a robotic arm clamps the sample tube on the lifting mechanism to the next station, the liquid inside the sample tube will not spill, thus improving the safety of the disordered sample feeding device for transporting the sample tube.

Detailed Implementation

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] See Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this application provides a disordered sample introduction system 10, including a frame 20, a sample introduction drawer 30, and a disordered sample introduction device 40. The frame 20 is provided with a mounting cavity 21. The sample introduction drawer 30 includes a drawer body 31 and a movable wall 32. The drawer body 31 can be slidably disposed in the mounting cavity 21 in the horizontal direction, forming a drawer cavity 31a. The movable wall 32 is movably connected to the drawer body 31. When the drawer body 31 is outside the mounting cavity 21, the movable wall 32 blocks the drawer cavity 31a. At this time, a sample tube 50 can be poured into the drawer cavity 31a without falling out. When the drawer body 31 is inside the mounting cavity 21, the movable wall 32 opens the drawer cavity 31a, and the sample tube 50 in the drawer cavity 31a falls from the drawer cavity 31a to the disordered sample introduction device 40, thus enabling the sample introduction drawer 30 to supply sample tubes 50 to the disordered sample introduction device 40.

[0054] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the sample inlet drawer 30 further includes a drawer motor 33, a connecting arm 34, a drive bearing 35, and a support shaft 36. A groove 22 is provided on the frame 20. The drawer motor 33 is mounted on the frame 20 and can drive the drawer body 31 to slide via a synchronous belt. The drive bearing 35 and the support shaft 36 are rotatably mounted at opposite ends of the connecting arm 34. The drive bearing 35 slides in conjunction with the groove 22, and the support shaft 36 is rotatably connected to the movable wall 32, which in turn is rotatably connected to the drawer body 31. When the drawer body 31 is gradually pushed out of the mounting cavity 21, the drive bearing 35 drives the movable wall 32 to rotate via the connecting arm 34 and the support shaft 36, thereby blocking the drawer cavity 31a. When the drawer body 31 is gradually pushed into the mounting cavity 21, the drive bearing 35 drives the movable wall 32 to rotate via the connecting arm 34 and the support shaft 36, thereby opening the drawer cavity 31a.

[0055] By sliding the sample inlet drawer 30 into the mounting cavity 21, the sample inlet drawer 30 will be housed in the mounting cavity 21 when there is no need to add the sample tube 50 into the sample inlet drawer 30. Therefore, the mounting cavity 21 can play a good role in housing and protecting the sample inlet drawer 30, preventing the sample inlet drawer 30 from occupying other space outside the mounting cavity 21, reducing the volume of the disordered sample inlet system 10, thereby improving the compactness and integration of the disordered sample inlet system 10 in terms of structure, and ultimately realizing the miniaturization design of the disordered sample inlet system 10.

[0056] In some embodiments, the disordered sample feeding device 40 is located below the sample feeding drawer 30, and the sample tube 50 in the drawer cavity 31a will fall into the disordered sample feeding device 40 under the action of gravity. The disordered sample feeding device 40 includes a frame 100, a hopper 200, a sieve tube mechanism 300, a blocking mechanism 400, a conveying mechanism 500, a side-pushing mechanism 600, a rotating mechanism 700, and a lifting mechanism 800. The hopper 200 is disposed on the frame 100 and has a receiving cavity 210 located below the drawer cavity 31a. The receiving cavity 210 is used to hold and receive the sample tube 50, that is, to receive the sample tube 50 that falls from the drawer cavity 31a. The receiving cavity 210 is an open cavity. Along the direction away from the opening of the receiving cavity 210, that is, from top to bottom, the diameter of the receiving cavity 210 can be reduced, so that the receiving cavity 210 is roughly conical. This makes it easier for the receiving cavity 210 to collect the sample tube 50 that falls from the drawer cavity 31a, and also makes it easier for the receiving cavity 210 to gather the sample tube 50 to the bottom of the receiving cavity 210 so that the sample tube 50 can be output from the receiving cavity 210 later.

[0057] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9In some embodiments, the sieve tube mechanism 300 is used to transport sample tubes 50 within the receiving cavity 210. The blocking mechanism 400 has a blocking position 410 for supporting sample tubes 50. The blocking position 410 can support only one sample tube 50 at a time, and its dimensions are suitable for supporting different types of sample tubes 50. The sieve tube mechanism 300 includes an input pusher 310. The end of the input pusher 310 has an input pusher ramp 311, which is set at an acute angle to the vertical direction. The input pusher ramp 311 supports the sample tube 50. The input pusher 310 is slidably connected to the frame 100 in the vertical direction. The input pusher 310 can be driven by a synchronous belt and can extend into the receiving cavity 210, thus allowing it to slide within the cavity. The input pusher 310 is used to input the sample tube 50 in the accommodating cavity 210 to the blocking position 410 of the blocking mechanism 400. Specifically, during the upward sliding of the input pusher 310 in the accommodating cavity 210, a sample tube 50 in the accommodating cavity 210 can be supported on the input pusher inclined surface 311. The sample tube 50 is horizontally set and lies on the input pusher inclined surface 311, so that the sample tube 50 moves upward with the input pusher 310. When the input pusher inclined surface 311 moves to the position corresponding to the blocking position 410, the sample tube 50 on the input pusher inclined surface 311 will slide into the blocking position 410 under the action of gravity. In this way, the input pusher 310 inputs the sample tube 50 in the accommodating cavity 210 to the blocking position 410 of the blocking mechanism 400.

[0058] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9In some embodiments, the sieve tube mechanism 300 further includes a first fixing member 320 and a first pushing member 330. The first fixing member 320 is fixedly connected to the frame 100 and has a first fixing inclined surface 321. The first fixing inclined surface 321 is set at an acute angle to the vertical direction and is used to support the sample tube 50. The first fixing inclined surface 321 can be parallel to the input pushing inclined surface 311. The first pushing member 330 is slidably connected to the frame 100 in the vertical direction. The first pushing member 330 can be driven by a synchronous belt and can extend into the receiving cavity 210, so the first pushing member 330 can slide in the receiving cavity 210. The first pusher 330 has a first pusher ramp 331, which is set at an acute angle to the vertical direction. The first pusher ramp 331 is used to support the sample tube 50 and can be parallel to the input pusher ramp 311. The first fixing member 320 is located between the input pusher 310 and the first pusher 330. The first fixing ramp 321 is located below the blocking position 410. During the upward movement of the first pusher 330 in the accommodating cavity 210, the input pusher ramp 311 and the first fixing ramp 321 are aligned and coplanar. A sample tube 50 in the accommodating cavity 210 can be supported on the first pusher ramp 331. The sample tube 50 is horizontally positioned and lies on the first pusher ramp 331. The first fixing member 320 can limit the sample tube 50 to prevent it from slipping off the first pusher ramp 331. When the first pushing ramp 331 and the first fixing ramp 321 are aligned and coplanar, the first fixing member 320 will lose its limiting function on the sample tube 50, causing the sample tube 50 on the first pushing ramp 331 to slide and fall onto the input pushing ramp 311 via the first fixing ramp 321. When the sample tube 50 is supported on the input pushing ramp 311, the input pushing member 310 will move upward, thereby allowing the input pushing member 310 to input the sample tube 50 from the receiving cavity 210 to the blocking position 410.

[0059] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 By setting the first fixing member 320 and the first pushing member 330, the total upward sliding stroke of the input pushing member 310 can be reasonably reduced. That is, the first pushing member 330 and the input pushing member 310 relay the sample tube 50. This avoids the sample tube 50 from falling during the transportation process, thereby improving the stability of the sample tube 50 transportation. On the other hand, it ensures that the sample tube 50 lies horizontally on the input pushing inclined surface 311 and the first pushing inclined surface 331 as much as possible, thereby ensuring that the sample tube 50 is transported in the correct posture, and ultimately improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0060] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the sieve tube mechanism 300 further includes a second fixing member 340 and a second pushing member 350. The second fixing member 340 is fixedly connected to the frame 100 and has a second fixing inclined surface 341. The second fixing inclined surface 341 is set at an acute angle to the vertical direction and is used to support the sample tube 50. The second fixing inclined surface 341 can be parallel to the input pushing inclined surface 311 and is located below the first fixing inclined surface 321. The second fixing member 340 is located between the first pushing member 330 and the second pushing member 350. The second pushing member 350 is slidably connected to the frame 100 in the vertical direction. The second pushing member 350 can be driven by a synchronous belt and can extend into the receiving cavity 210, so the second pushing member 350 can slide in the receiving cavity 210. The second pusher 350 has a second pusher slope 351, which is set at an acute angle to the vertical direction. The second pusher slope 351 is used to support the sample tube 50 and can be parallel to the input pusher slope.

[0061] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 During the upward movement of the second pusher 350 within the accommodating cavity 210, the first pusher ramp 331 and the second fixed ramp 341 are aligned and coplanar. A sample tube 50 within the accommodating cavity 210 can be supported on the second pusher ramp 351. The sample tube 50 is horizontally positioned on the second pusher ramp 351, and the second fixed member 340 can limit the sample tube 50, preventing it from slipping off the second pusher ramp 351. When the second pusher ramp 351 and the second fixed ramp 341 are aligned and coplanar, the second fixed member 340 loses its limiting function on the sample tube 50, causing the sample tube 50 on the second pusher ramp 351 to slide and fall from the second fixed ramp 341 to the first pusher ramp 331. When the sample tube 50 is supported on the first push slope 331, the first push member 330 will move upward. When the first push slope 331 and the first fixed slope 321 are aligned and coplanar, the sample tube 50 on the first push slope 331 will slide through the first fixed slope 321 into the input push slope 311, thereby allowing the input push member 310 to input the sample tube 50 from the accommodating cavity 210 to the blocking position 410.

[0062] See Figure 5 , Figure 6 , Figure 7, Figure 8 and Figure 9 By setting the second fixing member 340 and the second pushing member 350, the total upward sliding stroke of the first pushing member 330 can be reasonably reduced. That is, the first pushing member 330, the second pushing member 350, and the input pushing member 310 relay the sample tube 50. This avoids the sample tube 50 from falling during the transportation process, thereby improving the stability of the sample tube 50 transportation. On the other hand, it ensures that the sample tube 50 lies horizontally on the input pushing inclined surface 311, the first pushing inclined surface 331, and the second pushing inclined surface 351 as much as possible, thereby ensuring that the sample tube 50 is transported in the correct posture, and ultimately improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0063] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In the initial state, the second fixed inclined surface 341 and the first pushing inclined surface 331 are coplanar, and the first fixed inclined surface 321 and the input pushing inclined surface 311 are coplanar. During the upward movement of the sample tube 50 carried by the second pushing member 350, when the second pushing inclined surface 351 and the second fixed inclined surface 341 are coplanar, the sample tube 50 on the second pushing inclined surface 351 will slide through the second fixed inclined surface 341 into the first pushing inclined surface 331. At this time, the first pushing member 330 carries the sample tube 50 upward. When the first pushing inclined surface 331 and the first fixed inclined surface 321 are coplanar, the sample tube 50 on the first pushing inclined surface 331 will slide through the first fixed inclined surface 321 into the input pushing inclined surface 311. At this time, the input pushing member 310 will carry the sample tube 50 upward until the sample tube 50 is input to the blocking position 410.

[0064] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9In some embodiments, the screen tube mechanism 300 further includes a blocking member 360, which is located between the receiving cavity 210 and the blocking position 410. The blocking member 360 has a blocking inclined surface 361, which is set at an acute angle to the vertical direction. During the upward movement of the sample tube 50 carried by the input pusher 310, if the sample tube 50 is not horizontal but lies horizontally on the input pusher slope 311, for example, if the sample tube 50 is set vertically or tilted at an acute angle to the vertical direction, then as the sample tube 50 moves upward toward the blocking position 410, the vertically or tilted sample tube 50 will come into contact with the blocking slope 361, causing the blocking slope 361 to have a pushing effect on the vertically or tilted sample tube 50 on the input pusher slope 311, thereby pushing the sample tube 50 that is not being transported in the correct posture and causing it to fall into the receiving cavity 210, further improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0065] See Figure 10 and Figure 11 In some embodiments, the blocking mechanism 400 further includes a blocking member 420, a blocking motor 430, a blocking cam 440, and a blocking shaft 450. The blocking motor 430 is mounted on the frame 100, the blocking cam 440 can be connected to the output shaft of the blocking motor 430, and the blocking shaft 450 is mounted on the cam. The blocking shaft 450 and the blocking cam 440 are not coaxial; that is, the blocking shaft 450 is eccentrically positioned relative to the blocking cam 440. A guide rail extending vertically can be provided on the frame 100, and the blocking member 420 is slidably connected to the guide rail, allowing the blocking member 420 to slide vertically relative to the frame 100. The blocking member 420 is provided with a guide groove 421, which can be elongated, such as an oblong groove, and can extend a certain length horizontally. The blocking shaft 450 is slidably engaged with the guide groove 421. When the blocking motor 430 drives the blocking cam 440 to rotate, the blocking shaft 450 will reciprocate in the guide groove 421, thereby causing the blocking shaft 450 to drive the blocking member 420 to reciprocate in the vertical direction.

[0066] See Figure 10 and Figure 11The blocking position 410 can be located between the blocking member 420 and the aforementioned shielding member 360. When the sample tube 50 is located at the blocking position 410, when the blocking member 420 moves upward, a sufficiently large gap will be created below the blocking member 420. This gap can be understood as the gap formed between the blocking member 420 and the conveying mechanism 500. At this time, the blocking member 420 will lose its blocking function, and the sample tube 50 located at the blocking position 410 will automatically enter the conveying mechanism 500 through this gap under the action of gravity. When the blocking member 420 moves downward, the gap below the blocking member 420 will decrease until it disappears completely, and the blocking member 420 will exert a blocking effect, preventing the sample tube 50 located at the blocking position 410 from entering the conveying mechanism 500. It can be understood that when the sensor detects the presence of a sample tube 50 at the blocking position, but there is no sample tube 50 on the conveying mechanism 500, the blocking member 420 can be moved upward to eliminate the blocking effect, allowing the sample tube 50 to smoothly enter the conveying mechanism 500 from the blocking position 410.

[0067] See Figure 12 In some embodiments, the transport mechanism 500 has a first transport groove 511 and a second transport groove 512. The first transport groove 511 and the second transport groove 512 can extend horizontally and are used to carry the sample tube 50. Therefore, the sample tube 50 in the first transport groove 511 and the second transport groove 512 will be arranged horizontally. The height of the first transport groove 511 in the vertical direction can be higher than that of the second transport groove 512, that is, the first transport groove 511 is located above the second transport groove 512. The conveying mechanism 500 has a conveying ramp 520, which is set at an acute angle to the vertical direction. A first conveying groove 511 is located between a second conveying groove 512 and a blocking mechanism 400. The conveying ramp 520 is located between the second conveying groove 512 and a rotating mechanism 700. The first conveying groove 511 receives sample tubes 50 from the blocking position 410 of the blocking mechanism 400. The second conveying groove 512 receives sample tubes 50 from the first conveying groove 511. The sample tubes 50 on the second conveying groove 512 are conveyed to the rotating mechanism 700 via the conveying ramp 520. When the sensor detects that there are no sample tubes 50 in the second conveying groove 512, the sample tubes 50 on the first conveying groove 511 can be allowed to enter the second conveying groove 512. By setting up a second transport trough 512, when taking a picture of the sample tube 50 in the second transport trough 512, it is not affected that the sample tube 50 enters the first transport trough 511 from the blocking position 410. This can eliminate the intermediate waiting time and improve the transport efficiency of the sample tube 50.

[0068] See Figure 12In some embodiments, the conveying mechanism 500 further includes a conveying motor 530 and a conveying component 540. The conveying motor 530 can drive the conveying component 540 to rotate intermittently via a connecting rod or a synchronous belt. The conveying mechanism 500 also has a first clearance groove 551 and a second clearance groove 552. The first clearance groove 551 can be understood as being formed by a certain depth recess in the bottom wall of the first conveying groove 511, thus enabling the first clearance groove 551 to communicate with the first conveying groove 511. The second clearance groove 552 can be understood as being formed by a certain depth recess in the bottom wall of the second conveying groove 512, thus enabling the second clearance groove 552 to communicate with the second conveying groove 512. The transport component 540 includes a first actuating part 541 and a second actuating part 542, which are spaced apart. The first actuating part 541 is movably disposed in the first clearance groove 551 and can extend into or retract from the first transport groove 511. The second actuating part 542 is movably disposed in the second clearance groove 552 and can extend into or retract from the second transport groove 512.

[0069] See Figure 12 When it is necessary to output the sample tube 50 from the first clearance groove 551 and the second clearance groove 552, the transport motor 530 can drive the transport component 540 to move. The first actuating part 541 will extend into the first transport groove 511, so that the first actuating part 541 protrudes a certain height relative to the bottom wall of the first transport groove 511. At the same time, the second actuating part 542 will extend into the second transport groove 512, so that the second actuating part 542 protrudes a certain height relative to the bottom wall of the second transport groove 512. Then, the first actuating part 541 and the second actuating part 542 will rotate simultaneously by a certain angle. At this time, the first actuating part 541 will generate a actuating force on the sample tube 50 in the first transport groove 511, thereby pulling the sample tube 50 out of the first transport groove 511 and sliding it into the second transport groove 512 under the action of gravity; the second actuating part 542 will generate a actuating force on the sample tube 50 in the second transport groove 512, thereby pulling the sample tube 50 out of the second transport groove 512 and sliding it into the rotating mechanism 700 along the transport slope 520 under the action of gravity. It can be understood that when the transport member 540 moves, the first actuating part 541 and the second actuating part 542 on the transport member 540 will simultaneously generate actuating force on the first transport groove 511 located in the second transport groove 512. When there is no need to move or transport the sample tube 50, the first actuating part 541 and the second actuating part 542 can be disengaged from the first transport groove 511 and the second transport groove 512 respectively, so as to avoid interference between the first actuating part 541 and the second actuating part 542 and the sample tube 50.

[0070] Multiple first clearance slots 551 can be spaced out within the same first transport groove 511. The number of first clearance slots 551 is equal to the number of first actuating parts 541, and they correspond one-to-one. Similarly, multiple second clearance slots 552 can be spaced out within the same second transport groove 512. The number of second clearance slots 552 is equal to the number of second actuating parts 542, and they correspond one-to-one. By providing multiple first actuating parts 541 and multiple second actuating parts 542, a more balanced actuating force can be applied to the sample tube 50.

[0071] See Figure 13 and Figure 14 In some embodiments, the side-pushing mechanism 600 includes a side-pushing motor 610, a side-pushing member 620, a rotating member 630, and a receiving member 640. The side-pushing member 620 is slidably connected to the frame 100, allowing it to slide horizontally relative to the frame 100. The side-pushing motor 610 is mounted on the frame 100 and can drive the side-pushing member 620 to slide via a synchronous belt. The rotating member 630 is spaced horizontally from the side-pushing member 620. Both the side-pushing member 620 and the rotating member 630 are positioned corresponding to the second transport groove 512. The rotating member 630 is located at the end of the second transport groove 512. When one end of the rotating member 630 rotates away from the second transport groove 512, it opens the end of the second transport groove 512, allowing the sample tube 50 to detach from that end. When one end of the rotating member 630 rotates close to the second transport groove 512, the rotating member 630 can block the end of the second transport groove 512. At this time, under the limiting effect of the rotating member 630, the sample tube 50 is difficult to detach from the second transport groove 512 from that end.

[0072] When the sample tube 50 is located in the second transport trough 512, if the camera cannot identify the direction of the cap on the sample tube 50, the sample tube 50 is defective. At this time, when the side pusher 620 moves closer to the rotating member 630, it abuts against one end of the sample tube 50 and pushes the sample tube 50 closer to the rotating member 630 to slide. When the other end of the sample tube 50 abuts against the rotating member 630, the sample tube 50 continues to slide forward. The sample tube 50 pushes the rotating member 630 to overcome gravity and rotate away from the second transport trough 512, thereby opening the end of the second transport trough 512. The sample tube 50 will fall from the second transport trough 512 to the receiving member 640. It can be understood that the receiving member 640 is a container similar to the hopper 200 described above. When the cap of the sample tube 50 is oriented correctly, the sample tube 50 in the second transport groove 512 is unlikely to cause the rotating component 630 to rotate. The rotating component 630 will block the end of the second transport groove 512, thus limiting the sample tube 50 and effectively preventing the correct sample tube 50 from falling out of the second transport groove 512. When an incorrect sample tube 50 falls from the second transport groove 512 to the receiving component 640, the rotating component 630 will rotate close to the second transport groove 512 under its own gravity, blocking the end of the second transport groove 512. Since the incorrect sample tube 50 can be removed from the second transport groove 512, it can be ensured that the sample tube 50 is transported in the correct posture, ultimately improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0073] See Figure 15 and Figure 16In some embodiments, the rotating mechanism 700 has a discharge chamber 710 and a rotating chamber 720. The discharge chamber 710 is located below the rotating chamber 720 and the discharge chamber 710 and the rotating chamber 720 are interconnected. The rotating mechanism 700 includes a rotating component 730 and a rotating motor 740. The rotating motor 740 is mounted on the frame 100. The rotating component 730 is rotatably mounted in the rotating chamber 720. The rotating motor 740 can drive the rotating component 730 to rotate via a synchronous belt. The axis around which the rotating component 730 rotates extends horizontally and can be perpendicular to the extension direction of the second transport groove 512. In other words, the axis around which the rotating component 730 rotates can be perpendicular to the central axis of the sample tube 50 carried on the rotating component 730. The rotating component 730 is used to receive the sample tube 50 from the second transport groove 512. When the sample tube 50 is carried on the rotating component 730, the sample tube 50 is horizontal and lies horizontally on the rotating component 730. The cap on the horizontally lying sample tube 50 can be set to the right or left. At this point, the rotating component 730 can be rotated 90° counterclockwise or clockwise, thereby verticalizing the horizontally positioned sample tube 50 and ensuring that the cap of the sample tube 50 faces upwards, preventing the cap from facing downwards and thus preventing liquid spillage. This ensures that the sample tube 50 is transported in the correct orientation, ultimately improving the safety of the disordered sample delivery device 40 in transporting the sample tube 50.

[0074] See Figure 15 and Figure 16 Therefore, the rotating cavity 720 provides sufficient clearance for the rotation of the rotating component 730. When the rotating component 730 rotates in the rotating cavity 720, causing the sample tube 50 to be vertically positioned, the sample tube 50 will fall from the rotating component 730 through the rotating cavity 720 into the discharge cavity 710, and then extend into the lifting mechanism 800 through the discharge cavity 710. It can be understood that the diameter of the discharge cavity 710 can be reduced along the downward direction, making the discharge cavity 710 approximately conical. The sample tube 50 continuously adjusts its posture and accelerates its downward movement in the discharge cavity 710. When the sample tube 50 is output from the discharge cavity 710, the sample tube 50 can be in a completely vertical state, ensuring that the sample tube 50 enters the lifting mechanism 800 in a completely vertical state. This also ensures that the sample tube 50 is transported in the correct posture, ultimately improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0075] See Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21In some embodiments, the lifting mechanism 800 includes a lifting motor 810, a lifting chamber 820, a gripper 830, an elastic element 840, an opening / closing cam 850, and an abutment element 860. The lifting motor 810 is mounted on the frame 100, and the lifting chamber 820 is slidably connected to the frame 100 in the vertical direction. The lifting motor 810 can drive the lifting chamber 820 to slide up and down via a synchronous belt. The lifting chamber 820 has a chamber cavity 821, into which the sample tube 50 output from the discharge chamber 710 can enter, thereby enabling the lifting chamber 820 to carry and transport the sample tube 50. The middle part of the gripper 830 is rotatably connected to the lifting chamber 820, and the elastic element 840 abuts between the lifting chamber 820 and the opening / closing cam 850. For example, the elastic element 840 can abut between the lifting chamber 820 and the opening / closing cam 850 in the vertical direction, and the opening / closing cam 850 is slidably connected to the lifting chamber 820 in the vertical direction. The abutment member 860 is fixedly connected to the frame 100. When the abutment member 860 abuts against the lower end of the gripper finger 830, the upper end of the gripper finger 830 moves away from the lifting chamber 820. At this time, the interference of the gripper finger 830 can be eliminated, ensuring that the sample tube 50 in the discharge chamber 710 smoothly enters the chamber 821. When the abutment member 860 disengages from the lower end of the gripper finger 830, the elastic member 840 pushes the opening and closing cam 850 to abut against the lower end of the gripper finger 830, so that the upper end of the gripper finger 830 moves closer to the lifting chamber 820.

[0076] See Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21 The lifting mechanism 800 includes a lifting motor 810, a lifting chamber 820, a gripper finger 830, an elastic element 840, an opening / closing cam 850, and an abutment member 860. The lifting chamber 820 is slidably connected to the frame 100 in the vertical direction. The motor drives the lifting chamber 820 to move. The middle part of the gripper finger 830 is rotatably connected to the lifting chamber 820. The elastic element 840 abuts between the lifting chamber 820 and the opening / closing cam 850. The opening / closing cam 850 is slidably connected to the lifting chamber 820. The abutment member 860 is connected to the frame 100. When the abutment 860 abuts against the lower end of the gripper 830, the upper end of the gripper 830 moves away from the lifting chamber 820. When the abutment 860 disengages from the lower end of the gripper 830, the elastic element 840 pushes the opening and closing cam 850 to abut against the lower end of the gripper 830, so that the upper end of the gripper 830 moves closer to the lifting chamber 820, thereby making the gripper 830 clamp the sample tube 50 in the chamber 821 from left to right, preventing the sample tube 50 from shaking relative to the chamber 821.

[0077] See Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21For example, the opening / closing cam 850 has an inclined surface that gradually slopes towards the central axis of the lifting chamber 820 from top to bottom; the lower end of the gripper finger 830 also has an inclined surface that gradually slopes towards the central axis of the lifting chamber 820 from top to bottom. When the lifting chamber 820 moves downward and comes into contact with the abutment member 860, the abutment member 860 will cause the lower end of the gripper finger 830 to move inward toward the lifting chamber 820, thereby causing the upper end of the gripper finger 830 to move outward away from the lifting chamber 820, and the inclined surface at the lower end of the gripper finger 830 will push the opening / closing cam 850 upward through the inclined surface of the opening / closing cam 850, thereby compressing the elastic member 840 and storing energy. When the lifting chamber 820 moves upward, causing the gripper 830 to disengage from the abutment member 860, the elastic member 840 releases energy, pushing the opening / closing cam 850 downward. The opening / closing cam 850 pushes the lower end of the gripper 830 outward away from the lifting chamber 820, thereby causing the upper end of the gripper 830 to move inward towards the lifting chamber 820. This allows the gripper 830 to effectively hold the sample tube 50 in the chamber cavity 821. Multiple grippers 830 can be arranged at circumferential intervals along the lifting chamber 820.

[0078] See Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21 First, the lifting chamber 820 is located below the discharge chamber 710, meaning the chamber 821 is located below the discharge chamber 710. The abutment member 860 abuts against the lower end of the clamping finger 830, while the upper end of the clamping finger 830 moves outward away from the lifting chamber 820. This eliminates interference from the clamping finger 830, ensuring that the sample tube 50 falling from the discharge chamber 710 enters the chamber 821. Once the chamber 821 contains the sample tube 50, the lifting chamber 820 moves upward to the designated loading position. As the lifting chamber 820 moves upward towards the loading position, the abutment member 860 separates from the lower end of the clamping finger 830. The elastic member 840 then causes the clamping finger 830 to abut against the sample tube 50, creating a clamping effect and preventing the sample tube 50 from swaying relative to the chamber 821 or even detaching from the chamber 821. This improves the stability of the sample tube 50 transport. When the lifting chamber 820 reaches the feeding position, the sample tube 50 is set completely vertically with the cap of the sample tube 50 facing upwards. This ensures that the sample tube 50 is transported in the correct posture. When the robotic arm clamps the sample tube 50 on the lifting chamber 820 to the next station, the liquid in the sample tube 50 will not spill, thus improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0079] See Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21Furthermore, the lower end of the chamber 821 is a roughly conical segment 8211, meaning the diameter of the conical segment 8211 gradually decreases from bottom to top. A through hole 822 is also provided on the lifting chamber 820, connecting the outside to the upper end of the conical segment 8211. When the cap of the sample tube 50 in the chamber 821 is facing upwards, the lower end of the sample tube 50 will fill the conical segment 8211 and block the through hole 822. The light generated by the sensor will be reflected by the sample tube 50 and received through the through hole 822 to generate a signal. At this time, the sensor detects that the sample tube 50 is being transported in the correct orientation. When the cap of the sample tube 50 in the chamber 821 is facing downwards, the cap will not be able to enter the conical section 8211, so the through hole 822 is not blocked by the sample tube 50. The light generated by the sensor will pass through the through hole 822 and cannot receive the reflected signal. At this time, the sensor detects that the sample tube 50 is being transported in an incorrect posture and can reject the sample tube 50 that is being transported in an incorrect posture.

[0080] Therefore, through the combined action of the sieve tube mechanism 300, the blocking mechanism 400, the conveying mechanism 500, the side pushing mechanism 600, the rotating mechanism 700, and the lifting mechanism 800, when the sample tube 50 is finally output from the lifting mechanism 800, the sample tube 50 will be set completely vertically with the cap of the sample tube 50 facing upwards. This effectively prevents the sample tube 50 from tilting or even turning upside down, ensuring that the sample tube 50 is transported in the correct posture. When the robotic arm clamps the sample tube 50 on the lifting chamber 820 to the next station, the liquid in the sample tube 50 will not spill, thus improving the safety of the disordered sample feeding device 40 in transporting the sample tube 50.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
