Description

Technical Field

[0001] This application relates to the field of test tube conveying technology, and in particular to an active test tube conveying and feeding device. Background Technology

[0002] In the fields of laboratory testing, medical diagnosis, and biological sample processing, test tubes are widely used as basic experimental instruments for sample collection, storage, and analysis. With the development of automation technology, test tube loading equipment has become a key tool for improving experimental efficiency and reducing the intensity of manual operation.

[0003] In related technologies, a test tube feeding device typically includes a base plate, a storage rack, a guide rack, a conveying device, a pushing mechanism, and a conveying mechanism. Test tubes in the storage box fall along the guide rack under the action of gravity, and then are pushed into the storage rack by the linkage of the pushing rod and the pushing column. In addition, the conveying mechanism is driven by a drive motor to further transport the test tubes to a designated position.

[0004] However, although the above-mentioned existing technologies have improved the efficiency of test tube loading to some extent, they still have the following shortcomings. The existing technologies mainly rely on the weight of the test tubes themselves to achieve loading. When the test tubes get stuck due to arrangement problems, it is easy to cause loading interruption and affect the overall efficiency. If the test tubes are placed in the storage box in a disordered state, additional manual adjustment is required, which is difficult to meet the rapid processing needs of high-throughput laboratories. Utility Model Content

[0005] To address the aforementioned problems, this application provides an active test tube feeding device.

[0006] The test tube active conveying and feeding device provided in this application adopts the following technical solution: An active test tube conveying and feeding device is disclosed for conveying test tubes. It includes a first base plate, a feeding mechanism, and a conveying mechanism. The input ends of both the feeding mechanism and the conveying mechanism are fixed to the first base plate. The feeding mechanism includes a feeding assembly, a first lifting assembly, and a transmission assembly. The feeding assembly includes a spare parts bin, a discharge bin, a feeding plate, and a guide plate. Several feeding plates are provided. A bin block is provided within the spare parts bin. The bin block is slidably positioned within the spare parts bin via the first lifting assembly. The upper surface of the bin block is inclined. The configuration includes a hopper lifting mechanism that elevates and transports the test tubes to a discharge hopper. The discharge hopper is equipped with a pusher plate, which pushes the test tubes onto a feeding plate via a transmission assembly. Several feeding plates are fixed to the transmission assembly, which drives these feeding plates to carry the test tubes to a guide plate. One side of the guide plate is connected to the feeding mechanism, and the other side is fixedly connected to the conveying mechanism. The guide plate is inclined, allowing the test tubes to fall through it into the conveying mechanism.

[0007] By adopting the above technical solution, the problem of jamming caused by the reliance on the gravity of the test tubes for unloading in existing technologies is solved through the feeding and conveying mechanisms. Specifically, the bin is used to support the test tubes, and the first lifting component realizes the lifting and lowering of the bin, actively lifting and orderly unloading the test tubes. After the bin is lifted, due to its inclined setting, the test tubes can be guided to slide down the bin and gradually lifted to the unloading bin. The test tubes slide down the bin and fall into the unloading bin. At the same time, the pusher plate can directionally squeeze and organize the test tubes in the unloading bin, pushing the test tubes onto the feeding plate, supporting the random placement of test tubes and reducing the need for manual pre-arrangement. The transmission component drives the feeding plate to convey the test tubes to the guide plate, realizing the active pushing and orderly arrangement of the test tubes, reducing the jamming phenomenon caused by shape differences or arrangement problems. Combined with the inclined guide plate, the test tubes can slide down the inclined angle of the guide plate to the conveying mechanism, reducing the need for manual intervention. This not only improves the feeding efficiency and stability, but also meets the needs of high-throughput laboratories for rapid and continuous processing of test tubes.

[0008] Preferably, the system further includes a vertical plate and a first support plate. The transmission assembly includes a first drive motor, a first belt, a second belt, a first pulley, a second pulley, and guide rollers. The vertical plate is vertically fixed to the first base plate, and the first support plate is horizontally arranged and vertically fixed to the vertical plate. The input end of the conveying mechanism is fixed to the upper surface of the first support plate. The first drive motor is located on the lower surface of the first support plate and is fixedly connected to the vertical plate. First support frames are fixedly arranged at the upper and lower ends of the vertical plate. Two guide rollers are provided, and the two guide rollers are rotatably supported by the first support frames. The first belt is sleeved on the two guide rollers. The feeding plate is fixed on the first belt. Two second belts are provided. The output shaft of the first drive motor is coaxially fixed to the first pulley, and the second pulley is coaxially fixed to the guide roller located on the lower side of the vertical plate. One of the second belts is sleeved on the first pulley and the second pulley.

[0009] By adopting the above technical solution, the first drive motor drives the first pulley to rotate through the output shaft. The first pulley transmits power to the second pulley through the second belt sleeved on the first pulley. The rotation of the second pulley drives the guide roller, which is coaxially fixed to the second pulley, to rotate, thereby driving the upper guide roller to follow. The first belt on the guide roller rotates accordingly, forming a continuous circular motion. The first belt is sleeved on the two guide rollers. The rotation of the first belt directly drives the feeding plate fixed on the first belt to rotate synchronously, thereby enabling the test tubes to be conveyed in a circular manner on the first belt, so that the test tubes fall into the guide plate and are directionally conveyed along the guide tube to the conveying mechanism. By converting the rotational power of the first drive motor into the rotational motion of the feeding plate, this method replaces the traditional passive conveying method that relies on the gravity of the test tubes, effectively solving the problem of feeding interruption caused by test tube jamming or arrangement problems. At the same time, it supports the active sorting and efficient conveying of disordered test tubes.

[0010] Preferably, the transmission assembly further includes a third pulley, a fourth pulley, a sliding support, a push rod, and a sliding column. The end of the guide roller located on the lower side of the vertical plate, away from the second pulley, is coaxially fixed to the third pulley. The first base plate is provided with a second support frame, which is vertically fixed to the first base plate. The fourth pulley is rotatably supported on the second support frame. Another second belt is sleeved on the third pulley and the fourth pulley. The fourth pulley and the sliding support are provided with a crank-connecting rod assembly. The output end of the fourth pulley and the crank-connecting rod assembly are coaxially fixed. The input end of the crank-connecting rod assembly is fixedly connected to one end of the sliding support. The sliding column is vertically fixed to the first base plate. The sliding support is slidably disposed on the sliding column. One end of the push rod is vertically fixed to the sliding support, and the other end of the push rod is fixedly connected to the push plate.

[0011] By adopting the above technical solution, the rotation of the second pulley is driven by the second belt to rotate synchronously with the third pulley, which is coaxially fixed to the second pulley. The third pulley further drives the fourth pulley to rotate through the second pulley. The fourth pulley is coaxially fixed with the crank-connecting rod assembly. The rotational motion of the fourth pulley is converted into the linear reciprocating motion of the sliding support along the sliding column through the crank-connecting rod assembly. Since the push rod is vertically fixed on the sliding support, the sliding trajectory of the sliding support on the sliding column provides guidance for the push rod, enabling the push rod to periodically push the push plate. The reciprocating motion of the push rod directly drives the push plate to push the test tube from the discharge bin to the feeding plate, replacing the traditional passive conveying method of test tubes relying on gravity. This effectively solves the problem of jamming caused by disordered arrangement or shape differences of test tubes, further realizing the active and orderly pushing of test tubes, and significantly improving the feeding efficiency and system stability.

[0012] Preferably, the feeding plate includes a main board and a support block. A plurality of support blocks are provided, evenly distributed along the length of the main board. The support blocks are fixed perpendicularly to the main board. The main board is fixed to the first belt. A plurality of first sliding blocks are provided on the lower side of the push plate. When the push plate moves, the plurality of first sliding blocks slide between adjacent support blocks. A plurality of second sliding blocks are provided on the side of the guide plate near the first belt. When the first belt drives the plurality of feeding plates to rotate, the plurality of support blocks pass between adjacent second sliding blocks.

[0013] By adopting the above technical solution, several first sliding blocks on the lower side of the pusher plate are built between adjacent support blocks, ensuring that the pusher plate has less direct physical contact with the support blocks when moving, reducing jamming caused by friction or collision. At the same time, when the pusher plate pushes the test tube to the feeding plate, the side walls of several support blocks abut against the outer wall of the test tube, guiding the test tube to be arranged laterally along the length of the main plate through physical constraints. When the first belt rotates, the first belt drives several feeding plates to rotate, and the support blocks will slide down along the guide plate to the conveying mechanism between adjacent second sliding blocks on the side wall of the guide plate. The distance between adjacent second sliding blocks is less than the length of the test tube. The second sliding blocks form a limiting channel through the distance between adjacent support blocks to reduce the probability of the test tube passing through, significantly improving the feeding efficiency and system stability. It is especially suitable for the continuous processing needs in high-throughput laboratory scenarios, realizing interference-free pushing and orderly feeding of test tubes.

[0014] Preferably, it also includes a protective cover, the bottom of which is fixed to the conveying mechanism, and one side of which is fixedly connected to the feeding mechanism.

[0015] By adopting the above technical solution, a protective cover is set at the junction of the guide plate and the first conveying channel. The bottom of the guide plate is fixed to the first conveying channel and one side is connected to the feeding mechanism, which forms a protection for the test tube conveying path. This effectively reduces the risk of test tubes accidentally sliding out of the first conveying channel due to vibration, offset or edge collision when they roll down the guide plate to the first conveying channel. It also reduces the problem of leakage or operation interruption caused by test tubes falling, and improves the safety and reliability of equipment operation. It is especially suitable for continuous and automated test tube processing scenarios in high-throughput laboratories.

[0016] Preferably, the conveying mechanism includes a first conveying component and a second conveying component. The first conveying component includes a first conveying channel, a fifth pulley, and a third belt. The first conveying channel is fixed to the first support plate and extends to the outside of the first support plate and is fixedly connected to the second conveying component. There are two fifth pulleys, which rotate along the length of the first conveying channel and are supported on the inner sidewall of the first conveying channel. The third belt is sleeved on the two fifth pulleys, and the guide plate is fixed to the outer sidewall of the first conveying channel.

[0017] By adopting the above technical solution, the conveying mechanism achieves efficient and stable transmission of test tubes through the coordinated work of the first and second conveying components. The guide plate is fixed to the outer wall of the first conveying channel, and the inclined setting of the guide plate guides the test tubes to slide down from the feeding plate along the guide plate to the third belt, ensuring the directional arrangement of the test tubes when they fall into the third belt and reducing the risk of blockage caused by disorder. The first conveying channel extends to the outside of the first support plate and connects with the second conveying component to form a segmented conveying system. This not only achieves continuous transmission of test tubes, but also adapts to the processing needs of different workstations through segmented control, improving the overall flexibility and stability of the equipment. The third belt serves as a support for the test tubes, and the rotation of the fifth pulley drives the third belt to rotate, transporting the test tubes to the second conveying component.

[0018] Preferably, it further includes a cap removal mechanism. The second conveying assembly includes a second conveying channel, a second drive motor, and a lever. One end of the second conveying channel is fixedly connected to and communicates with the first conveying channel. The second conveying channel is inclined. The other end of the second conveying channel is fixedly connected to the cap removal mechanism. The test tube is provided with a snap-fit ​​component and a test tube cap. The snap-fit ​​component rotatably supports the test tube cap. The width of the second conveying channel is greater than the diameter of the test tube and less than the diameter of the test tube cap. There are two second drive motors, both of which are located on the outer wall of the second conveying channel near the end of the cap removal mechanism. The lever is coaxially fixed with the output shaft of the second drive motor.

[0019] By adopting the above technical solution, the width of the second conveying channel is greater than the diameter of the test tube but smaller than the diameter of the test tube cap. When the test tube slides into the channel, the rotating connection between the locking component and the test tube cap can adapt to different falling angles of the test tube. This allows the locking component and the test tube cap to be secured to the upper surface of the second conveying channel due to the width limitation. Since the second conveying channel is inclined, the test tube and test tube cap slide down the second conveying channel to the cap removal mechanism. Physical constraints ensure that the test tube and test tube cap remain in a stable sliding state within the second conveying channel during the sliding process. To reduce the risk of test tubes and caps falling off or becoming misaligned due to gravity, the inclined second conveying channel uses gravity to assist test tubes and caps in sliding towards the cap removal mechanism. This reduces the need for additional drive devices, enabling continuous conveying, lowering energy consumption, and improving efficiency. Simultaneously, the output shaft of the second drive motor is coaxially fixed with the lever to cut the test tubes, pushing any unsecured test tubes into the second conveying channel, securing the caps onto the second conveying channel, and adjusting the caps to a uniform orientation to ensure the accuracy and stability of subsequent cap removal operations.

[0020] Preferably, it further includes a second base plate and a second lifting assembly. The cap removal mechanism is fixed on the second base plate. The cap removal mechanism includes a third drive motor, a first lifting assembly, a turntable, and a gripping component. The third drive motor is located below the turntable and is fixed to the lower surface of the second base plate. A retaining seat is provided on the turntable. The output shaft of the third drive motor passes through the second base plate and is coaxially fixed to the retaining seat. The retaining seat is connected to the second conveying channel. The test tube enters the retaining seat. The retaining component abuts against the outer wall of the test tube and the inner wall of the retaining seat. The test tube cap abuts against the upper surface of the turntable. The gripping component is located above the retaining seat and performs vertical displacement through the second lifting assembly.

[0021] By adopting the above technical solution, the test tube is stably clamped in the holder by the contact between the clamping component and the outer wall of the test tube and the inner wall of the holder. This reduces the displacement or detachment of the test tube due to vibration or turntable rotation during the cap removal process. At the same time, the contact between the test tube cap and the upper surface of the turntable further fixes the position of the test tube cap through physical constraints, ensuring that the gripper accurately grasps the test tube cap under the drive of the second lifting component. This reduces cap removal failure or cap jamming problems caused by test tube shaking, significantly improving the stability and success rate of the cap removal operation. It is especially suitable for continuous and automated processing needs in high-throughput scenarios.

[0022] By adopting the above technical solution In summary, this application includes at least one of the following beneficial technical effects: 1. The spare parts compartment is equipped with a liftable compartment. The inclined surface of the compartment guides the test tubes to slide along the upper surface of the compartment and be lifted to the discharge compartment. The pusher plate in the discharge compartment pushes the test tubes to the feeding plate through the transmission component. The transmission component drives multiple feeding plates to transport the test tubes to the guide plate in an orderly manner. The inclined structure of the guide plate further assists the test tubes to slide down to the conveying mechanism. Through the active lifting of the compartment, the orientation and sorting of the pusher plate and the linkage control of the transmission component, it supports random placement of test tubes, reducing the need for manual pre-arrangement. At the same time, the connection between the inclined guide plate and the conveying mechanism ensures a smooth transition of the test tubes, which significantly improves the feeding efficiency and system stability, meets the stringent requirements of high-throughput laboratories for continuous and automated processing of test tubes, and effectively reduces the risks of manual intervention and equipment operation. 2. The first drive motor drives the first pulley to rotate, and the power is transmitted to the second pulley and the lower guide roller fixed coaxially with the second pulley via the second belt. This drives the upper and lower guide rollers to rotate synchronously, so that the first belt sleeved on the guide roller forms a continuous circular motion. The feeding plate fixed on the first belt rotates accordingly, thereby actively conveying the test tubes to the guide plate and orienting them into the conveying mechanism. This design converts the rotational power into the cyclical motion of the feeding plate through the mechanical linkage driven by the first drive motor, replacing the traditional passive conveying method that relies on gravity. This effectively solves the problem of feeding interruption caused by test tube jamming or arrangement problems. At the same time, it supports the active sorting and efficient conveying of disordered test tubes, significantly improving the operating efficiency and stability of the equipment and meeting the needs of high-throughput laboratories for continuous and automated processing. 3. When the pusher plate moves, the first sliding block slides between adjacent support blocks, reducing direct contact with the support blocks and lowering the risk of jamming caused by friction or collision. The side wall of the support block abuts against the outer wall of the test tube, guiding the test tube to be arranged laterally along the length of the main plate through physical constraints, ensuring stable positioning of the test tube during the pushing process. When the first belt drives the feeding plate to rotate, the support block forms a limiting channel between adjacent second sliding blocks set by the guide plate. The distance between adjacent second sliding blocks is less than the length of the test tube, effectively limiting the probability of the test tube passing through and forcing the test tube to slide down along the guide plate to the conveying mechanism. This achieves reduced interference pushing and orderly unloading, significantly improving feeding efficiency and system stability. It is especially suitable for high-throughput laboratories with stringent requirements for continuous and automated processing of test tubes. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses an active test tube conveying and feeding device. (Refer to...) Figure 1 and Figure 2An active test tube feeding device is provided for feeding test tubes 14. It includes a first base plate 1, a feeding mechanism, and a conveying mechanism. The input ends of both the feeding mechanism and the conveying mechanism are fixed to the first base plate 1. The feeding mechanism includes a feeding assembly, a first lifting assembly 12, and a transmission assembly. The feeding assembly includes a spare parts bin 71, a discharge bin 73, a feeding plate 75, and a guide plate 76. Several feeding plates 75 are provided. A bin block 72 is provided within the spare parts bin 71. The bin block 72 is slidably positioned within the spare parts bin 71 via the first lifting assembly 12. The upper surface is inclined. The lifting block 72 lifts the test tube 14 and transports it to the discharge bin 73. The discharge bin 73 is equipped with a push plate 74. The push plate 74 pushes the test tube 14 into the feeding plate 75 through the transmission assembly. Several feeding plates 75 are fixed on the transmission assembly. The transmission assembly drives several feeding plates 75 to carry the test tube 14 and feed it to the guide plate 76. One side of the guide plate 76 is connected to the feeding mechanism, and the other side of the guide plate 76 is fixedly connected to the conveying mechanism. The guide plate 76 is inclined, and the test tube 14 falls into the conveying mechanism through the guide plate 76.

[0032] This demonstrates that by using the feeding mechanism and the conveying mechanism, the jamming problem caused by the existing technology mainly relying on the gravity of the test tube 14 itself for unloading is solved. Specifically, the bin 72 is used to support the test tube 14, and the first lifting component 12 realizes the lifting and lowering of the bin 72, actively lifting and orderly unloading the test tube 14. After the bin 72 is lifted, since the bin 72 is inclined, it can guide the test tube 14 to slide down along the bin 72 and gradually be lifted to the unloading bin 73. The test tube 14 slides down along the bin 72 and falls into the unloading bin 73.

[0033] Meanwhile, the pusher plate 74 can directionally squeeze and arrange the test tubes 14 in the discharge bin 73, pushing the test tubes 14 onto the feeding plate 75, supporting the random placement of the test tubes 14, reducing the need for manual pre-arrangement. The transmission component drives the feeding plate 75 to transport the test tubes 14 to the guide plate 76, realizing the active pushing and orderly arrangement of the test tubes 14, reducing the jamming phenomenon of the test tubes 14 caused by shape differences or arrangement problems. Combined with the inclined guide plate 76, the test tubes 14 slide down the inclined angle of the guide plate 76 to the conveying mechanism, reducing the need for manual intervention. This not only improves the feeding efficiency and stability, but also meets the needs of high-throughput laboratories for rapid and continuous processing of test tubes 14.

[0034] Specifically, the first lifting assembly 12 includes a second support plate 5, a fourth drive motor 121, a fourth belt 122, a sixth pulley 123, a linear guide rail 124, and a sliding connector 125. The first base plate 1 is provided with the second support plate 5, which is vertically fixed to the first base plate 1. The first drive motor 81 is fixed to the upper side of the second support plate 5. Two sixth pulleys 123 are provided, and the sixth pulleys 123 rotate along the vertical length direction of the second support plate 5 and are supported at both ends of the second support plate 5. The fourth belt 122 is fitted onto the two sixth pulleys 123. The fourth drive motor 121 passes through the second support plate 5 and is coaxially fixed with the sixth pulley 123 located on the upper side of the second support plate 5. The linear guide rail 124 is fixed on the second support plate 5 and is parallel to the fourth belt 122. The sliding connector 125 is slidably connected to the linear guide rail 124. One end of the sliding connector 125 is fixedly connected to the fourth belt 122, and the other end of the sliding connector 125 is fixedly connected to the inner wall of the spare parts compartment 71.

[0035] This illustrates that the fourth drive motor 121 drives the sixth pulley 123 to rotate, which in turn drives the fourth belt 122, which is sleeved on the two sixth pulleys 123, to move. One end of the sliding connector 125 is fixed to the fourth belt 122, and the other end is connected to the inner wall of the bin 72. This converts the rotational motion of the fourth belt 122 into the linear reciprocating motion of the sliding connector 125 along the linear guide rail 124, thereby achieving the active lifting and orderly feeding of the test tubes 14 inside the bin 72. Furthermore, the storage block 72 is tilted, which allows the test tube 14 to roll to the lower side under its own weight, regardless of how it is placed in the spare parts storage 71. This is beneficial for subsequent loading operations. For example, even if the test tube 14 is placed in the spare parts storage 71 in a random order, its position can be automatically adjusted by the tilting structure of the storage block 72.

[0036] To further explain, the lifting of the bin 72 causes the test tube 14 to slide down into the discharge bin 73. This process realizes the transformation of the test tube 14 from the storage state to the ready-to-feed state. The push plate 74 pushes the test tube 14 into the feeding plate 75 through the transmission component. The transmission component drives several feeding plates 75 to carry the test tube 14 to the guide plate 76. The push plate 74 is set as a flat plate structure. One side of the guide plate 76 is connected to the feeding mechanism, and the other side is fixedly connected to the conveying mechanism. The guide plate 76 is tilted at a certain angle, and the test tube 14 falls into the conveying mechanism through the tilt angle of the guide plate 76.

[0037] Reference Figure 3 and Figure 4Furthermore, it also includes a vertical plate 3 and a first support plate 4. The transmission assembly includes a first drive motor 81, a first belt 82, a second belt 83, a first pulley 84, a second pulley 85, and a guide roller 86. Specifically, the vertical plate 3 is vertically fixed on the first base plate 1, the first support plate 4 is horizontally set and vertically fixed to the vertical plate 3, the input end of the conveying mechanism is fixed on the upper surface of the first support plate 4, the first drive motor 81 is located on the lower surface of the first support plate 4, the first drive motor 81 is fixedly connected to the vertical plate 3, and the first drive motor 81 is the power source of the entire transmission assembly.

[0038] Furthermore, a first support frame 16 is fixedly installed at the upper and lower ends of the vertical plate 3, and two guide rollers 86 are provided. The two guide rollers 86 are rotatably supported on the first support frame 16. A first belt 82 is sleeved on the two guide rollers 86. Several feeding plates 75 are provided, and all feeding plates 75 are fixed on the first belt 82. Two second belts 83 are provided. The output shaft of the first drive motor 81 is coaxially fixed to the first pulley 84, and the second pulley 85 is coaxially fixed to the guide rollers 86 located on the lower side of the vertical plate 3. One of the second belts 83 is sleeved on the first pulley 84 and the second pulley 85.

[0039] This explains that several feeding plates 75 are fixed on the first belt 82. When the first drive motor 81 is working, it drives the second belt pulley 85 to rotate through the first belt pulley 84, which in turn drives the first belt 82 to rotate. Since the feeding plates 75 are fixed on the first belt 82, the feeding plates 75 are driven to rotate to perform the feeding action.

[0040] Furthermore, the transmission assembly also includes a third pulley 89, a fourth pulley 810, a crank connecting rod assembly 18, a sliding support 812, a push rod 813, and a sliding column 814. Specifically, the guide roller 86 located on the lower side of the vertical plate 3 is coaxially fixed to the third pulley 89 at one end away from the second pulley 85. A second support frame 17 is provided on the first base plate 1 and is vertically fixed to the first base plate 1. The fourth pulley 810 is rotatably supported on the second support frame 17. Another second belt 83 is sleeved on the third pulley 89 and the fourth pulley 810.

[0041] Meanwhile, the fourth pulley 810 is coaxially fixed to the output end of the crank-connecting rod assembly 18, and the input end of the crank-connecting rod assembly 18 is fixedly connected to one end of the sliding support 812. Specifically, the crank-connecting rod assembly 18 includes a transmission rod 181 and a transmission block 182. The fourth pulley 810 is coaxially fixed to the transmission rod 181, and the transmission block 182 is hinged to the side of the transmission rod 181 away from the fourth pulley 810. A connecting member 19 is provided between the transmission block 182 and the sliding support 812. The connecting member 19 is fixedly connected to the sliding support 812, and the transmission block 182 is hinged to the connecting member 19. The sliding column 814 is vertically fixed on the first base plate 1. In this embodiment, there are two sliding columns 814. The sliding support 812 is slidably disposed on the sliding column 814. One end of the push rod 813 is vertically fixed to the sliding support 812, and the other end of the push rod 813 is fixedly connected to the push plate 74.

[0042] Furthermore, when the guide roller 86 rotates, it drives the fourth pulley 810 to rotate via the third belt 93, which in turn drives the crank connecting rod assembly 18 to work. The fourth pulley 810 rotates under the drive of the motor, and the transmission block 182, which is coaxially fixed with the fourth pulley 810, rotates synchronously. Since the transmission block 182 is hinged to the transmission rod 181, the rotational motion of the transmission rod 181 drives the transmission block 182 to reciprocate. The oscillation of the transmission block 182 is transmitted to the connecting member 19, which is fixed on the sliding support member 812. The rotational oscillation is converted into the linear reciprocating motion of the connecting member 19. The linear motion of the connecting member 19 directly drives the sliding support member 812 to slide up and down along the sliding column 814, thereby realizing the periodic pushing of the push rod 813 on the push plate 74, and further realizing the action of the push plate 74 pushing the test tube 14 into the loading plate 75.

[0043] In addition, the feeding plate 75 includes a main board 751 and a support block 752. Several support blocks 752 are provided, and the several support blocks 752 are evenly distributed along the length direction of the main board 751. The support blocks 752 are fixed perpendicularly to the main board 751. The surface of the support block 752 is provided with a recessed structure. The main board 751 is fixed on the first belt 82. Several first sliding blocks 741 are provided on the lower side of the push plate 74. When the push plate 74 moves, the several first sliding blocks 741 are all built into the adjacent support blocks 752. Several second sliding blocks 761 are provided on the side of the guide plate 76 near the first belt 82. When the first belt 82 drives the several feeding plates 75 to rotate, the several support blocks 752 pass between the adjacent second sliding blocks 761.

[0044] This explains that the several first sliding blocks 741 on the lower side of the push plate 74 are built between adjacent support blocks 752, ensuring that the push plate 74 has less direct physical contact with the support blocks 752 when it moves, reducing jamming caused by friction or collision. At the same time, when the push plate 74 pushes the test tube 14 to the feeding plate 75, the side walls of the several support blocks 752 abut against the outer wall of the test tube 14, guiding the test tube 14 to be arranged laterally along the length of the main plate 751 through physical constraints. When the first belt 82 rotates, the first belt 82 drives the several feeding blocks 752 to rotate. When plate 75 rotates, the bearing block 752 will slide down along the guide plate 76 to the conveying mechanism between the adjacent second sliding blocks 761. The distance between the adjacent second sliding blocks 761 is less than the length of the test tube 14. The second sliding blocks 761 form a limiting channel through the distance between the adjacent bearing blocks 752 to reduce the probability of the test tube 14 passing through. This significantly improves the feeding efficiency and system stability, and is especially suitable for continuous processing requirements in high-throughput laboratory scenarios, realizing the non-interference pushing and orderly feeding of the test tube 14.

[0045] It should be noted that the recessed structure on the surface of the support block 752 is specially designed for the test tube 14. When the test tube 14 is pushed into the support block 752, the recessed part can hold the test tube 14 in place, reducing the sliding or tilting of the test tube 14 due to inertia during the rotation of the feeding plate 75.

[0046] Meanwhile, a protective cover 77 is provided at the connection between the guide plate 76 and the conveying mechanism. The bottom of the protective cover 77 is fixed to the conveying mechanism, and one side of the protective cover 77 is fixedly connected to the feeding mechanism. The protective cover 77 is provided at the connection between the guide plate 76 and the first conveying channel 91. The bottom of the guide plate 76 is fixed to the first conveying channel 91 and one side is connected to the feeding mechanism, which forms protection for the conveying path of the test tube 14. This effectively reduces the risk of the test tube 14 accidentally sliding out of the first conveying channel 91 due to vibration, offset or edge collision when it rolls down the guide plate 76 to the first conveying channel 91. It also reduces the problem of leakage or operation interruption caused by the test tube 14 falling, and improves the safety and reliability of the equipment operation. It is especially suitable for continuous and automated test tube 14 processing scenarios in high-throughput laboratories.

[0047] Reference Figure 5Furthermore, the conveying mechanism includes a first conveying component 9 and a second conveying component 10. The first conveying component 9 includes a first conveying channel 91, a fifth pulley 92, and a third belt 93. The first conveying channel 91 is fixed on the first support plate 4 and extends to the outside of the first support plate 4 to connect with the second conveying component 10. There are two fifth pulleys 92. The two fifth pulleys 92 rotate along the length of the first conveying channel 91 and are supported at both ends of the first conveying channel 91. The third belt 93 is sleeved on the two fifth pulleys 92. The guide plate 76 is fixed to the outer wall of the first conveying channel 91. When the test tube 14 falls into the first conveying channel 91 through the guide plate 76, it is conveyed forward along the first conveying channel 91 under the drive of the third belt 93.

[0048] Reference Figure 6 Furthermore, this embodiment also includes a cap removal mechanism 11. The second conveying assembly 10 includes a second conveying channel 101, a second drive motor 102, and a lever 103. The second conveying channel 101 is inclined. One end of the second conveying channel 101 is fixedly connected to and communicates with the first conveying channel 91, and the other end is fixedly connected to the cap removal mechanism 11. The test tube 14 is provided with a snap-fit ​​component 151 and a test tube 14 cap. The snap-fit ​​component 151 is rotatably supported by the test tube 14 cap. The diameter of the second conveying channel 101 is larger than the diameter of the test tube 14, and the diameter of the second conveying channel 101 is smaller than the diameter of the test tube 14 cap. In this way, when the test tube 14 enters the second conveying channel 101, the test tube 14 can pass smoothly, while the test tube 14 cap and the snap-fit ​​component 151 will be snapped on the upper surface of the second conveying channel 101.

[0049] Meanwhile, since the second conveying channel 101 is inclined, the test tube 14 and the test tube 14 cap slide down the second conveying channel 101 to the cap removal mechanism 11. Physical constraints ensure that the test tube 14 and the test tube 14 cap are always in a stable sliding state in the second conveying channel 101 during the sliding process, reducing the drop or misalignment of the test tube 14 and the test tube 14 cap due to gravity. The inclined second conveying channel 101 uses gravity to assist the test tube 14 and the test tube 14 cap to slide to the cap removal mechanism 11, reducing the need for additional drive devices to achieve continuous conveying, reducing energy consumption and improving efficiency.

[0050] Furthermore, two second drive motors 102 are provided, both of which are located on the side wall of the second conveying channel 101 near the cap removal mechanism 11. The lever 103 is coaxially fixed with the output shaft of the second drive motor 102. When the test tube 14 is conveyed to the position of the lever 103, the test tube 14 is cut off, and the unattached test tube 14 is pushed into the second conveying channel 101. The cap of the test tube 14 is then attached to the second conveying channel 101, and the caps of the test tube 14 are adjusted to a uniform orientation to ensure the accuracy and stability of the subsequent operation of the cap removal mechanism 11.

[0051] Furthermore, it also includes a second lifting assembly 13 and a second base plate 2. The cap removal mechanism 11 and the second lifting assembly 13 are both fixed on the second base plate 2. The cap removal mechanism 11 includes a third drive motor 111, a turntable 112, and a gripper 113. The third drive motor 111 is located below the turntable 112 and is fixed to the lower surface of the second base plate 2. The output shaft of the third drive motor 111 passes through the second base plate 2 and is coaxially fixed to the card holder 1121. The card holder 1121 is provided on the turntable 112 and is connected to the second conveying channel 101. The test tube 14 enters the card holder 1121, and the outer wall of the card holder 151 abuts against the inner wall of the card holder 1121. The cap of the test tube 14 abuts against the upper surface of the turntable 112. The gripper 113 is located above the card holder 1121 and performs vertical displacement through the second lifting assembly 13.

[0052] This demonstrates that by abutting the outer wall of the test tube 14 and the inner wall of the holder 1121 with the snap-fit ​​151, the test tube 14 is stably clamped in the holder 1121, reducing the displacement or detachment of the test tube 14 due to vibration or rotation of the turntable 112 during the cap removal process. At the same time, the abutting between the cap of the test tube 14 and the upper surface of the turntable 112 further fixes the position of the cap of the test tube 14 through physical constraints, ensuring that the gripper 113 accurately grips the cap of the test tube 14 under the drive of the second lifting component 13, reducing the failure to remove the cap or the problem of the cap getting stuck due to the shaking of the test tube 14. The gripper 113 is set as a mechanical claw, which can firmly grip the cap of the test tube 14.

[0053] Furthermore, the second lifting assembly 13 includes a fifth drive motor 131, a seventh pulley 132, a fifth belt 133, and a third support plate 6. The third support plate 6 is vertically fixed on the second base plate 2. The fifth drive motor 131 is fixed on the upper side of the third support plate 6. There are two seventh pulleys 132. The seventh pulleys 132 rotate along the vertical length direction of the third support plate 6 and are supported at both ends of the third support plate 6. The fifth belt 133 is sleeved on the two seventh pulleys 132. The fifth drive motor 131 passes through the third support plate 6 and is coaxially fixed with the seventh pulley 132 located on the upper side of the third support plate 6. The gripping member 113 is fixed on the belt.

[0054] This demonstrates that the second lifting component 13 drives the seventh pulley 132 to rotate via the fifth drive motor 131, which in turn drives the fifth belt 133 to reciprocate along the vertical direction of the third support plate 6, thereby driving the gripper 113 to achieve precise vertical displacement. This also adapts to the requirements of high-frequency continuous operation, further improving the efficiency of the cap removal mechanism 11 and the overall stability of the equipment, making it particularly suitable for automated processing needs in high-throughput laboratory scenarios.

[0055] The implementation principle of a test tube active conveying and feeding device according to an embodiment of this application is as follows: Test tubes are randomly placed into the spare parts bin and fall onto the bin block. The first lifting component drives the bin block to rise vertically. The inclined structure of the bin block causes the test tubes to slide towards the discharge bin. After the bin block is raised, the test tubes slide into the discharge bin. The transmission component drives the push plate to move periodically. The first drive motor drives the first pulley to rotate. The second pulley is fixed coaxially with the guide roller. Since the second belt is sleeved on the first pulley, the guide roller is driven to rotate through the second belt, which in turn drives the third and fourth pulleys to rotate. The crank-connecting rod assembly converts the rotational motion of the fourth pulley into the linear reciprocating motion of the sliding support, which further realizes the linear reciprocating motion of the push rod. The push rod drives the push plate to push the test tube into the recessed structure of the bearing block of the feeding plate, thereby realizing the orientation and sorting of the disordered test tubes.

[0056] The feeding plate rotates with the first belt, and the bearing block guides the test tubes to be arranged laterally along the length of the main plate through physical constraints. The concave structure prevents the test tubes from sliding, and the test tubes slide down the inclined guide plate into the first conveying channel of the conveying mechanism. The test tube enters the first conveying channel through the guide plate. The third belt drives the test tube forward along the first conveying channel to the inclined second conveying channel. The test tube enters the inclined second conveying channel, and the test tube cap and clamp are clamped on the upper surface of the channel. The second drive motor drives the lever to rotate, cuts off the test tube and adjusts the direction of the test tube cap to a uniform orientation to ensure the accuracy of subsequent cap removal operations.

[0057] The test tube slides into the turntable's holder from the second conveying channel. The outer wall of the clamping component abuts against the inner wall of the holder to achieve axial fixation. The bottom of the test tube cap abuts against the upper surface of the turntable. The third drive motor drives the turntable to rotate, causing the test tube to rotate slightly through the holder until it is below the gripper. The fifth drive motor drives the seventh pulley to rotate, causing the fifth belt to move vertically along the third support plate. The gripper fixed on the belt then descends vertically to accurately grip the test tube cap.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
