Description

Technical Field

[0001] This application relates to the technical field of medical device equipment, and particularly relates to a tube picking device for a test tube labeling machine. Background Art

[0002] Currently, most hospitals use vacuum test tubes to draw patients' blood, and different test tubes are distinguished by different sizes and colors according to different test items of patients. To ensure that each patient's test tube is not confused with others, the patient's information needs to be printed on a label paper and then pasted on the corresponding test tube.

[0003] In related technologies, the tube picking device of a test tube labeling machine includes a machine body and a manipulator arranged on the machine body. A plurality of tube storage boxes for storing different test tubes are arranged on the machine body. A scanner for scanning patients' information is arranged on the machine body, and the scanner is connected to an external controller. The manipulator is used to grab test tubes. During use, the patients' information is scanned by the scanner, and then the controller analyzes the patients' information and drives the manipulator to grab the test tubes in the appropriate tube storage box, and then moves the test tubes and places them at the inlet of the printing and labeling machine.

[0004] Regarding the above related technologies, when there are multiple test tubes arranged horizontally in the tube storage box, it is not convenient for the manipulator to reach into the tube storage box to pick up a single test tube. Summary of the Invention

[0005] To facilitate picking up a single test tube, this application provides a tube picking device for a test tube labeling machine.

[0006] The tube picking device for a test tube labeling machine provided by this application adopts the following technical solution:

[0007] A tube-taking device of a test tube labeling machine, comprising a machine body and a plurality of tube storage boxes installed on the machine body. A notch for the test tube to fall through is formed in the bottom wall of the tube storage box. A tube-taking bin is arranged on the machine body, and the tube-taking bins correspond to the tube storage boxes one by one. The tube-taking bin is located below the corresponding tube storage box. A rotating rod is rotatably arranged in the tube-taking bin, and the rotation axis of the rotating rod is parallel to the length direction of the test tubes in the corresponding tube storage box. The distance between the inner walls on both sides of the tube-taking bin where the rotating rod is located decreases in the direction away from the tube storage box. A sector block is arranged on the rotating rod, and receiving grooves for receiving the test tubes are formed on both side surfaces of the sector block. A limiting plate is arranged on the rotating rod, and the limiting plate straddles the rotating rod. The limiting plate is located on the side of the rotating rod away from the sector block. When the limiting plate is in the horizontal direction, the horizontal distance from the side of the limiting plate to the inner wall of the tube-taking bin close to one side is less than the diameter of the test tube. A driving member for driving the corresponding rotating rod to rotate is arranged on the tube-taking bin. An outlet is formed on the machine body and is communicated with the inlet of the labeling device. The outlet is located below the tube-taking bin. A transportation mechanism is arranged in the machine body, and the transportation mechanism is used to transport the test tubes that fall into the receiving grooves to the outlet.

[0008] By adopting the above technical solution, in the initial state, the sector block is located below the limiting plate, and the limiting plate is horizontally arranged, so that the test tubes in the tube storage box are blocked by the limiting plate and are not easily dropped directly into the tube-taking bin. After the scanner scans the patient information, the controller controls the driving member at the required position to work. The driving member drives the corresponding rotating rod to rotate, causing the limiting plate to gradually tilt, and the receiving groove near the upper end of the limiting plate rotates upward, and the receiving groove near the lower end of the limiting plate rotates downward. As the limiting plate gradually tilts, the horizontal distance between the upper end of the limiting plate and the inner wall of the tube-taking bin gradually increases until it is greater than the diameter of the test tube. At this time, the test tube can fall from between the upper end of the limiting plate and the inner wall of the tube-taking bin into the receiving groove on the corresponding side. Then the driving member drives the rotating rod to reverse, causing the limiting plate to reverse, and the limiting plate continues to block the test tubes in the tube storage box, so as to achieve taking only one test tube when there are multiple test tubes horizontally arranged in the tube storage box. Then the rotating rod continues to reverse, and the receiving groove containing the test tube gradually flips to pour out the test tube. The transportation mechanism transports the dropped test tube to the outlet, so as to achieve taking a single test tube each time.

[0009] Preferably, the outlet pipe orifice is located on one side in the arrangement direction of the plurality of storage tube boxes. The transportation mechanism includes a transport vehicle slidably arranged in the machine body, a baffle slidably arranged on the transport vehicle, an adjustment assembly arranged on the transport vehicle, and a sliding member arranged in the machine body. The transport vehicle is located below the tube taking bin. The transport vehicle is used for transporting the test tubes dropped into the receiving groove. The sliding direction of the transport vehicle is parallel to the arrangement direction of the plurality of storage tube boxes. The transport vehicle slides in a direction close to or away from the outlet pipe orifice. An opening for the test tubes to drop through is formed in the bottom wall of the transport vehicle. The baffle is used to block or open the opening. The baffle slides in a direction close to or away from the opening. The adjustment assembly is used to adjust the sliding of the baffle in a direction close to or away from the opening. The sliding member is used to drive the transport vehicle to slide.

[0010] By adopting the above technical solution, the sliding member is used to drive the transport vehicle to move below the required tube taking bin. When the test tubes in the receiving groove drop, the transport vehicle receives the dropped test tubes. Then, the sliding member is used to drive the transport vehicle to slide in a direction close to the outlet pipe orifice, so that the opening of the transport vehicle gradually moves to align with the outlet pipe orifice. The adjustment assembly is used to adjust the baffle to slide relative to the transport vehicle in a direction away from the opening. At this time, the baffle opens the opening, and the test tubes in the transport vehicle enter the outlet pipe orifice through the opening, realizing the transportation of the test tubes, which is helpful for taking a single test tube.

[0011] Preferably, the adjustment assembly includes a connecting plate slidably arranged on the transport vehicle, an abutting block arranged in the machine body, and a pulling member arranged on the transport vehicle. The connecting plate is connected to the baffle. The sliding direction of the baffle is parallel to the sliding direction of the transport vehicle. The sliding direction of the connecting plate is parallel to the sliding direction of the baffle. The abutting block is located on one side of the outlet pipe orifice and corresponds to the position of the connecting plate. The abutting block is used to abut against the connecting plate to slide relative to the transport vehicle in a direction away from the opening. The pulling member is used to pull the baffle to slide relative to the transport vehicle in a direction close to the opening.

[0012] By adopting the above technical solution, when the transport vehicle slides in a direction close to the outlet pipe orifice, the connecting plate gradually approaches the abutting block. Then, the connecting plate moves to abut against the abutting block. At this time, when the transport vehicle continues to approach the outlet pipe orifice, the abutting block will limit the movement of the connecting plate and the baffle, causing the baffle and the connecting plate to slide relative to the transport vehicle in a direction away from the opening, thereby realizing the opening of the opening, so that the test tubes can fall into the outlet pipe orifice through the opening. When the transport vehicle slides in a direction away from the outlet pipe orifice, the pulling member is used to pull the baffle to slide relative to the transport vehicle in a direction close to the opening, so as to facilitate closing the opening, thus facilitating the next transportation of the test tubes.

[0013] Preferably, the pulling member includes a first tension spring for pulling the baffle in a direction close to the opening. One end of the first tension spring is arranged on the transport vehicle, and the other end is arranged on the baffle.

[0014] By adopting the above technical solution, the baffle is pulled by the first tension spring to slide relative to the transport vehicle towards the direction close to the opening, so as to facilitate closing the opening, thereby facilitating the transportation of the test tubes and providing convenience for tube extraction.

[0015] Preferably, the sliding member includes pulleys rotatably arranged on opposite sides inside the machine body, a belt wound around the two pulleys, and a first motor arranged inside the machine body. The rotation axis of the pulley is perpendicular to the sliding direction of the transport vehicle. The transport vehicle is connected to one side of the belt. The first motor is used to drive the pulley at any end to rotate. The tube outlet is located between the two side pulleys. The first motor is used to be connected to an external controller.

[0016] By adopting the above technical solution, when the first motor is started, the first motor drives the corresponding pulley to rotate, and then the belt conveys. When the belt moves, it drives the transport vehicle to move, which helps to move the transport vehicle to the required position.

[0017] Preferably, a flow dividing plate is arranged on the side of the limiting plate away from the sector block. The distance between the two sides of the flow dividing plate gradually decreases towards the direction close to the sector block.

[0018] By adopting the above technical solution, when the test tube falls in the tube storage box, it is divided into two sides along the flow dividing plate, which provides convenience for tube extraction from the receiving grooves on both sides.

[0019] Preferably, limiting blocks are arranged on opposite sides of the tube extraction bin. The arrangement direction of the two limiting blocks is perpendicular to the rotation axis of the rotating rod. The limiting blocks are used to abut against the edge of the receiving groove on the closer side. When the edge of the receiving groove abuts against the limiting block on the closer side, the horizontal distance between the corresponding side edge of the limiting plate and the inner wall of the tube extraction bin on the closer side is greater than the diameter of the test tube.

[0020] By adopting the above technical solution, the arrangement of the limiting blocks helps to limit the rotation angle of the sector block, and it is not likely that the sector block rotates excessively due to machine failure.

[0021] Preferably, a guiding block is arranged on the side of the rotating rod away from the sector block. The guiding block is arranged along the length direction of the rotating rod. The distance between the two sides of the guiding block gradually increases towards the direction away from the rotating rod. The limiting plate straddles the guiding block.

[0022] By adopting the above technical solution, the arrangement of the guiding block provides a certain guiding for the test tube to fall into the receiving groove, which provides convenience for tube extraction.

[0023] Preferably, a transport channel is provided inside the machine body. The transport vehicle is slidably arranged in the transport channel. The tube-taking bin is located above the transport channel. The outlet is opened on the bottom wall of the transport channel. Two support rods are hinged to one side of the transport vehicle. The hinge axis of the support rods is parallel to the rotation axis of the rotating rod. The two support rods are inclined upward in the direction away from each other. The first guide wheels are installed at the ends of the two support rods away from the transport vehicle. A second tension spring for pulling each other is arranged between the two support rods. One end of the second tension spring is arranged on one support rod, and the other end is arranged on the other support rod.

[0024] By adopting the above technical solution, the second tension spring has a mutual pulling force on the two support rods, making the two support rods tend to rotate upward, which helps to make the two first guide wheels closely abut against the top wall of the transport channel, improving the smoothness of the movement of the transport vehicle to a certain extent.

[0025] Preferably, a tray for opening and closing the notch is slidably arranged on the bottom wall of the tube storage box. The sliding direction of the tray is perpendicular to the arrangement direction of the plurality of tube storage boxes. The tube storage box slides in the direction of approaching or departing from the notch. The tube storage box is detachably connected to the corresponding tube-taking bin.

[0026] By adopting the above technical solution, the detachable connection between the tube storage box and the tube-taking bin helps to remove the tube storage box from the machine body for loading tubes, which is simple and convenient. After installing the tube storage box filled with test tubes on the corresponding tube-taking bin and then sliding the tray in the direction away from the notch, the notch can be opened, facilitating the test tubes to enter the tube-taking bin from the notch.

[0027] In summary, the present application includes the following beneficial technical effects:

[0028] After the scanner scans the patient information, the controller controls the driving member at the required position to work. The driving member drives the corresponding rotating rod to rotate, causing the limiting plate to gradually tilt. As the limiting plate gradually tilts, the horizontal distance between the upper end of the limiting plate and the inner wall of the tube-taking bin gradually increases until it is greater than the diameter of the test tube. At this time, the test tube can fall from between the upper end of the limiting plate and the inner wall of the tube-taking bin into the corresponding receiving groove on one side. Then the driving member drives the rotating rod to reverse, causing the limiting plate to reverse. The limiting plate continues to block the test tubes in the tube storage box. Then the receiving groove containing the test tubes gradually flips to pour out the test tubes. Then the dropped test tubes are transported to the outlet through the transport mechanism, thus realizing the tube-taking of a single test tube each time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will further elaborate on the present application in conjunction with the attached Figures 1-7 drawings.

[0038] An embodiment of the present application discloses a tube taking device for a test tube labeling machine. Referring to Figure 1 and Figure 2 , the tube taking device of the test tube labeling machine includes a body 1 and a plurality of tube storage boxes 2 installed on the body 1. The plurality of tube storage boxes 2 are arranged along the length direction of the body 1. A notch 3 for allowing the test tube to fall is provided on the bottom wall of the tube storage box 2, and the cross-sectional area of the notch 3 is equal to the cross-sectional area of the tube storage box 2.

[0039] Referring to Figure 2 and Figure 3, a tube-taking bin 4 is fixedly arranged on the body 1. The tube-taking bin 4 is a structure with upper and lower openings 11 running through. The cross-section of the tube-taking bin 4 is rectangular. The tube-taking bin 4 corresponds to the tube storage box 2 one by one. The tube storage box 2 is installed above the corresponding tube-taking bin 4. A rotating rod 5 is rotatably arranged in each tube-taking bin 4. The rotation axis of the rotating rod 5 is parallel to the length direction of the test tube in the corresponding tube storage box 2. The arrangement direction of the multiple tube storage boxes 2 is perpendicular to the rotation axis of the rotating rod 5. The tube-taking bin 4 successively includes a first section 41, a second section 42 and a third section 43 from top to bottom. The distance between the two sides of the first section 41 relative to the rotating rod 5 is greater than the distance between the two sides of the third section 43 relative to the rotating rod 5. The distance between the two sides of the second section 42 relative to the rotating rod 5 gradually decreases in the direction approaching the third section 43. The rotating rod 5 is flush with the side of the third section 43 close to the second section 42. The tube storage box 2 is installed on the side of the first section 41 away from the second section 42.

[0040] Referring to Figure 2 and Figure 3 , a sector block 6 is fixedly connected to the rotating rod 5. The sector block 6 is arranged along the length direction of the rotating rod 5 and is coaxially arranged with the rotating rod 5. Receiving grooves 7 for receiving test tubes are formed on both side surfaces of the sector block 6. A diversion block 14 is fixed on the side of the rotating rod 5 away from the sector block 6. The diversion block 14 is arranged along the length direction of the rotating rod 5. The distance between both sides of the diversion block 14 gradually decreases in the direction away from the rotating rod 5. The longitudinal section of the diversion block 14 is triangular. A limiting plate 8 is fixedly connected to the side of the diversion block 14 away from the sector block 6. The limiting plate 8 is located in the middle of the rotating rod 5. The limiting plate 8 straddles the rotating rod 5 and the diversion block 14. The longitudinal section of the limiting plate 8 is trapezoidal. The length of the side of the limiting plate 8 close to the sector block 6 is greater than the length of the side of the limiting plate 8 away from the sector block 6. When the limiting plate 8 is in the horizontal direction, the horizontal distance from the side of the limiting plate 8 to the corresponding side of the tube-taking bin 4 is less than the diameter of the test tube. A diversion plate 12 is integrally formed on the side of the limiting plate 8 away from the sector block 6. The distance between both sides of the diversion plate 12 gradually decreases in the direction approaching the sector block 6. The longitudinal section of the diversion plate 12 is triangular.

[0041] Referring to Figure 2 and Figure 3, a driving member for driving the corresponding rotating rod 5 to rotate is provided on the tube storage bin 4. In this embodiment, the driving member includes a second motor 20 installed on the outer wall of the tube storage bin 4, and the rotating rod 5 is coaxially fixed to the output shaft of the corresponding second motor 20. The second motor 20 is connected to an external controller; in other embodiments, the second motor 20 can be replaced by an electric motor; a transportation channel 15 is formed in the machine body 1, and the transportation channel 15 is located below the tube storage bin 4. A plurality of tube storage bins 4 communicate with the transportation channel 15. An outlet pipe orifice 9 for communicating with the inlet of the labeling device is formed in the bottom wall of the transportation channel 15. The outlet pipe orifice 9 is located below the tube storage bin 4 and on one side in the arrangement direction of the plurality of tube storage bins 4. A transportation mechanism 10 is arranged in the transportation channel 15, and the transportation mechanism 10 is used to transport the test tubes dropped into the receiving groove 7 into the outlet pipe orifice 9.

[0042] Referring to Figure 2 and Figure 4 , the transportation mechanism 10 includes a transport vehicle 101 slidably arranged in the transportation channel 15, a baffle 102 slidably arranged on the transport vehicle 101, an adjustment assembly 103 arranged on the transport vehicle 101, and a sliding member 104 arranged in the transportation channel 15. The transport vehicle 101 is located below the tube storage bin 4 and is used to receive the test tubes dropped from the receiving groove 7. The sliding direction of the transport vehicle 101 is parallel to the arrangement direction of the plurality of storage tube boxes 2. The transport vehicle 101 slides in a direction close to or away from the outlet pipe orifice 9. An opening 11 for allowing the test tubes to drop is formed in the bottom wall of the transport vehicle 101. The baffle 102 is used to block or open the opening 11. The sliding direction of the baffle 102 is parallel to the sliding direction of the transport vehicle 101. The baffle 102 slides in a direction close to or away from the opening 11. Guide plates 21 are fixed to opposite sides of the transport vehicle 101. The guide plates 21 are located above the opening 11. The arrangement direction of the two guide plates 21 is parallel to the sliding direction of the transport vehicle 101. The distance between the two guide plates 21 gradually decreases in the direction close to the opening 11, which helps to guide and buffer the test tubes; the adjustment assembly 103 is used to adjust the sliding of the baffle 102 in a direction close to or away from the opening 11, and the sliding member 104 is used to drive the transport vehicle 101 to slide.

[0043] Referring to Figure 5 and Figure 6, to facilitate the movement of the transport vehicle 101, the sliding member 104 includes pulleys 1041 rotatably provided on opposite sides of the transport passage 15, a belt 1042 wound around the two pulleys 1041, and a first motor 1043 fixedly installed in the transport passage 15. The rotation axis of the pulley 1041 is perpendicular to the sliding direction of the transport vehicle 101, the rotation axis of the pulley 1041 is arranged in the vertical direction, the arrangement direction of the two pulleys 1041 is parallel to the arrangement direction of the plurality of storage tube boxes 2, the two pulleys 1041 are drivingly connected through the belt 1042, the transport vehicle 101 is fixedly connected to one side of the belt 1042, the belt 1042 on the other side slides through the transport vehicle 101, the outlet pipe 9 is located between the two pulleys 1041 on both sides, the pulley 1041 close to one side of the outlet pipe 9 is coaxially fixed to the output shaft of the first motor 1043, and the first motor 1043 is used to be connected to an external controller.

[0044] In the initial state, the sector block 6 is located below the limit plate 8, and the limit plate 8 is arranged horizontally. The test tubes in the tube storage box 2 close to the diverter plate 12 are divided to both sides under the action of the diverter plate 12 and the guide block 14. The limit plate 8 blocks the test tubes, making it difficult for the test tubes to fall directly into the transport channel 15; after the scanner scans the patient information, the controller controls the first motor 1043 to work and the second motor 20 at the required position to work, the first motor 1043 drives the pulley 1041 to rotate, and drives the transport vehicle 101 to move to the bottom of the required tube removal bin 4 through the belt 1042, and the second motor 20 drives the corresponding rotating rod 5 rotates, causing the limiting plate 8 to gradually tilt, and the receiving groove 7 near the upper end of the limiting plate 8 rotates upward, and the receiving groove 7 near the lower end of the limiting plate 8 rotates downward. As the limiting plate 8 gradually tilts, the horizontal distance between the upper end of the limiting plate 8 and the inner wall of the tube-taking bin 4 gradually increases until it is larger than the diameter of the test tube. At this time, the test tube can fall from between the upper end of the limiting plate 8 and the tube-taking bin 4 to the receiving groove 7 on the corresponding side. Since the spacing between the two opposite sides of the third section 43 is smaller than the spacing between the two opposite sides of the first section 41, the test tube cannot fall from the gap between the lower end of the limiting plate 8 and the tube-taking bin 4. One side of the block 6 abuts against the outer wall of the test tube in the receiving groove 7, and then the second motor 20 drives the rotating rod 5 to reverse, so that the limiting plate 8 gradually reverses to continue to block the other test tubes in the tube storage box 2, so that only one test tube is taken out of the receiving groove 7; the rotating rod 5 reverses, and the receiving groove 7 containing the test tube is gradually turned over to pour out the test tube, and the test tube falls into the transport vehicle 101, and when the limiting plate 8 rotates upward in the opposite direction, the test tube passes through the upper end of the limiting plate 8 and the tube taking bin 4 and falls into the receiving groove 7 without the test tube, and then the second motor 20 drives the rotating rod 5 to reverse and drive the limiting plate 8 to be in a horizontal state, and at this time, the receiving groove 7 on one side is A test tube is held inside so that it can be directly taken out next time; when the transport vehicle 101 receives the test tube, the first motor 1043 drives the pulley 1041 to rotate, so that the belt 1042 is transmitted, and the belt 1042 drives the transport vehicle 101 to move in the direction close to the pipe outlet 9, until the transport vehicle 101 is moved to the pipe outlet 9, the baffle 102 is adjusted by the adjustment component 103 to slide in the direction away from the opening 11, and the opening 11 is opened. Then the test tube in the transport vehicle 101 enters the pipe outlet 9 through the opening 11. When multiple test tubes are horizontally installed in the tube storage box 2, it can also be achieved that only a single test tube is taken out each time.

[0045] Reference Figure 5 and Figure 7, To facilitate the adjustment of the sliding of the baffle 102, the adjustment assembly 103 includes a connecting plate 1031 slidably arranged on the transport vehicle 101, an abutting block 1032 fixedly arranged on the bottom wall of the transport channel 15, and a pulling member 1033 arranged on the transport vehicle 101. The connecting plate 1031 is fixedly connected to the baffle 102. The sliding direction of the connecting plate 1031 is parallel to the sliding direction of the baffle 102. The abutting block 1032 is located on one side of the outlet pipe 9 and corresponds to the position of the connecting plate 1031. The abutting block 1032 is used to abut the connecting plate 1031 to slide relative to the transport vehicle 101 in the direction away from the opening 11. A U-shaped groove 22 for the abutting block 1032 to pass through is formed on one side of the bottom wall of the transport vehicle 101 close to the abutting block 1032, and the U-shaped groove 22 corresponds to the position of the abutting block 1032. The pulling member 1033 is used to pull the baffle 102 to slide relative to the transport vehicle 101 in the direction close to the opening 11. The pulling member 1033 includes a first tension spring 10331 for pulling the baffle 102 to slide in the direction close to the opening 11. One end of the first tension spring 10331 is fixedly connected to the transport vehicle 101, and the other end is fixedly connected to one side of the baffle 102 close to the abutting block 1032. The telescopic direction of the first tension spring 10331 is parallel to the sliding direction of the baffle 102.

[0046] When the transport vehicle 101 carries a test tube and slides in the direction close to the outlet pipe 9, the connecting plate 1031 gradually approaches the abutting block 1032 until the abutting block 1032 abuts against the connecting plate 1031. At this time, when the transport vehicle 101 continues to move, the abutting block 1032 blocks the connecting plate 1031, so that the connecting plate 1031 drives the baffle 102 to move relative to the transport vehicle 101 in the direction away from the opening 11. As the opening 11 is opened, the transport vehicle 101 moves above the outlet pipe 9. At this time, the test tube in the transport vehicle 101 enters the outlet pipe 9 through the opening 11; then the transport vehicle 101 slides in the direction away from the outlet pipe 9. At this time, the transport vehicle 101 approaches the baffle 102 and the connecting plate 1031. The first tension spring 10331 pulls the baffle 102 to slide relative to the transport vehicle 101 in the direction close to the opening 11 until the opening 11 is blocked, thereby realizing the adjustment of the baffle 102.

[0047] Refer to Figure 3 , Limit blocks 13 are fixedly arranged on both opposite sides of the tube taking bin 4. The limit blocks 13 are located at the intersection of the third section 43 and the second section 42. The arrangement direction of the two limit blocks 13 is perpendicular to the rotation axis of the rotating rod 5. The limit blocks 13 are used to abut against the edge of the receiving groove 7 on the near side. When the edge of the receiving groove 7 abuts against the limit block 13 on the near side, the horizontal distance from the corresponding side of the limit plate 8 to the inner wall of the tube taking bin 4 on the near side is greater than the diameter of the test tube. The setting of the limit blocks 13 helps to limit the rotation angle of the sector block 6, so that the rotating rod 5 is not prone to excessive rotation.

[0048] Refer toFigure 4 and Figure 5 On one side of the transport vehicle 101 away from the belt 1042, two support rods 16 are hinged. The hinge axis of the support rods 16 is parallel to the rotation axis of the rotating rod 5. The two support rods 16 are inclined upward in the direction away from each other, that is, the distance between the two support rods 16 gradually increases in the direction away from the transport vehicle 101. At one end of the two support rods 16 away from the transport vehicle 101, a first guide wheel 17 is installed. The rotation axis of the first guide wheel 17 is parallel to the hinge axis of the support rods 16. A second tension spring 18 for pulling each other is arranged between the two support rods 16. One end of the second tension spring 18 is fixedly connected to one side support rod 16, and the other end is fixedly connected to the other side support rod 16. The telescopic direction of the second tension spring 18 is arranged along the horizontal direction. Under the pulling force of the second tension spring 18, the two support rods 16 have a tendency to rotate upward, which helps the two first guide wheels 17 to be in close contact with the top wall of the transport channel 15, and helps to improve the smoothness of the movement of the transport vehicle 101.

[0049] Refer to Figure 4 and Figure 5 On both opposite sides of the transport vehicle 101, two second guide wheels 23 are installed. The rotation axis of the second guide wheels 23 is parallel to the rotation axis of the rotating rod 5. On the bottom wall of the transport channel 15, a first guide groove 24 for sliding cooperation with the second guide wheels 23 is opened.

[0050] Refer to Figure 5 and Figure 7 On one side of the transport vehicle 101 close to the belt 1042, two third guide wheels 25 are installed. The rotation axis of the third guide wheels 25 is arranged along the vertical direction. On the top wall of the transport channel 15, a second guide groove 26 for sliding cooperation with the third guide wheels 25 is opened. The sliding cooperation between the second guide wheels 23 and the first guide groove 24, and the sliding cooperation between the third guide wheels 25 and the second guide groove 26 help to guide the movement of the transport vehicle 101 and further improve the movement effect of the transport vehicle 101.

[0051] Refer to Figure 2 and Figure 3 Refer to

[0052] When the test tubes in the storage tube box 2 are used up, slide the support plate 19 into the chute 27, slide the support plate 19 in the direction close to the notch 3 to close the notch 3 with the support plate 19; then directly remove the storage tube box 2 from the tube taking bin 4 for loading tubes, and then install the storage tube box 2 on the corresponding tube taking bin 4 so that the buckle 29 is engaged with the protrusion 28. Then slide the support plate 19 in the direction away from the notch 3 and slide the support plate 19 out of the chute 27 to open the notch 3, facilitating the entry of the test tubes into the tube taking bin 4 from the notch 3.

[0053] The implementation principle of the embodiment of the present application is as follows: During use, install the storage tube box 2 containing different test tubes on the corresponding tube taking bin 4 so that the buckle 29 is engaged with the protrusion 28. Then control the second motor 20 to work through the controller. The second motor 20 drives the rotating rod 5 to rotate, making the limiting plate 8 in the horizontal direction and the limiting plate 8 above the sector block 6; then slide the support plate 19 in the direction away from the notch 3 to move the support plate 19 out of the chute 27. At this time, the test tubes in the storage tube box 2 fall into the corresponding tube taking bin 4, and then under the action of the flow dividing plate 12, the test tubes close to the flow dividing plate 12 are located on both sides of the flow dividing plate 12.

[0054] After the scanner scans the patient information, the controller controls the first motor 1043 and the second motor 20 at the required position to work. The first motor 1043 drives the belt pulley 1041 to rotate, and drives the transport vehicle 101 to move below the required tube taking bin 4 through the belt 1042. The second motor 20 drives the corresponding rotating rod 5 to rotate, causing the limiting plate 8 to gradually tilt. As the limiting plate 8 gradually tilts, the horizontal distance between the upper end of the limiting plate 8 and the inner wall of the tube taking bin 4 gradually increases until it is greater than the diameter of the test tube. At this time, the edge of the upwardly rotating receiving groove 7 abuts against the corresponding limiting block 13, and the test tube falls from between the upper end of the limiting plate 8 and the tube taking bin 4 into the receiving groove 7 on the corresponding side. The side of the limiting plate 8 close to the sector block 6 abuts against the outer wall of the test tube. Then the second motor 20 drives the rotating rod 5 to reverse, causing the limiting plate 8 to gradually reverse to continue blocking other test tubes in the storage tube box 2. The receiving groove 7 containing the test tube gradually flips to pour out the test tube, and the test tube falls into the transport vehicle 101. When the limiting plate 8 rotates upward in the reverse direction, the test tube can fall from between the upper end of the limiting plate 8 and the tube taking bin 4 into the receiving groove 7 without test tubes. Then the second motor 20 drives the rotating rod 5 to reverse to drive the limiting plate 8 to be in a horizontal state. At this time, one side of the receiving groove 7 contains a test tube, which is convenient for direct use next time.

[0055] After the transport vehicle 101 catches the test tube, the first motor 1043 drives the pulley 1041 to rotate, so that the belt 1042 drives the transport vehicle 101 to move towards the direction close to the outlet pipe 9 until the abutting block 1032 passes through the U-shaped groove 22 and abuts against the connecting plate 1031. At this time, the transport vehicle 101 continues to move, and the abutting block 1032 blocks the connecting plate 1031 and the baffle 102, so that the baffle 102 slides relative to the transport vehicle 101 in the direction away from the opening 11, stretching the first tension spring 10331; until the transport vehicle 101 moves to the position of the outlet pipe 9, the opening 11 is completely opened, and the opening 11 corresponds to the outlet pipe 9. At this time, the test tube in the transport vehicle 101 enters the outlet pipe 9 through the opening 11, realizing taking the tube for only a single test tube each time.

[0056] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
