Referring to fig. 1 to 11 of the drawings, a tube changing system according to a preferred embodiment of the present utility model will be disclosed and described in the following description, wherein the tube changing system includes a tube changing device 100 and at least one tube holder 200, a tube 300 can be mounted on the tube holder 200, and the tube 300 moves and/or changes lanes with the movement and/or changing lanes of the tube holder 200 when the tube changing device 100 moves and/or changes lanes the tube holder 200.

Specifically, the tube lane-changing device 100 comprises a conveyor unit 10 and a lane-changing unit 20, wherein the conveyor unit 10 comprises a first conveyor belt 11, a second conveyor belt 12 and a conveyor rack 13, the first conveyor belt 11 and the second conveyor belt 12 being rotatably mounted to the conveyor rack 13, respectively, and at least a portion of the first conveyor belt 11 and at least a portion of the second conveyor belt 12 being adjacent, wherein the lane-changing unit 20 comprises a turntable 21, the turntable 21 having a radial gap 211, the turntable 21 being rotatably arranged above the adjacent positions of the first conveyor belt 11 and the second conveyor belt 12 to allow the radial gap 211 of the turntable 21 to rotate to a position corresponding to the second conveyor belt 12, at least a portion of the turntable 21 being capable of allowing the radial gap 211 of the turntable 21 to exist when energized, the turntable 21 and the tube holder 200 of the turntable 21 interacting with the magnetic element 200 to allow the tube holder 200 to be held in the radial gap 211.

That is, when at least a part of the turntable 21 is energized to cause the radial notch 211 of the turntable 21 to have an electromagnetic field, the electromagnetic field of the turntable 21 and the magnetic element 210 of the cuvette holder 200 can reliably hold the cuvette holder 200 at the radial notch 211 of the turntable 21 based on a magnetic attraction force, and when the turntable 21 is deenergized, the electromagnetic field of the radial notch 211 of the turntable 21 disappears, and at this time the cuvette holder 200 can be disengaged from the radial notch 211 of the turntable 21. That is, the tube lane changing apparatus 100 of the present utility model can control whether the radial notch 211 of the turntable 21 has an electromagnetic field by controlling the turning on/off of at least a portion of the turntable 21, so that the turntable 21 can catch the tube holder 200 to allow the tube holder 200 to be reliably held at the radial notch 211 of the turntable 21, or the turntable 21 can release the tube holder 200 to allow the tube holder 200 to be transferred with the rotation of the first conveyor belt 11 or the second conveyor belt 12.

In the present utility model, the first conveyor belt 11 drives the test tube holder 200 to transfer based on friction force when rotating, that is, the test tube holder 200 can be directly placed on the upper surface of the first conveyor belt 11 to allow the test tube holder 200 to be located above the first conveyor belt 11, and as the first conveyor belt 11 rotates, the test tube holder 200 can be moved by the first conveyor belt 11 based on friction force generated between the test tube holder 200 and the first conveyor belt 11. Accordingly, the second conveyor belt 12 drives the test tube holder 200 to transfer based on friction force when rotating, that is, the test tube holder 200 can be directly placed on the upper surface of the second conveyor belt 12 to allow the test tube holder 200 to be located above the second conveyor belt 12, and as the second conveyor belt 12 rotates, the test tube holder 200 can be driven to move by the second conveyor belt 12 based on friction force generated between the test tube holder 200 and the second conveyor belt 12.

It will be appreciated that the first conveyor belt 11 may be an endless track, for example, the first conveyor belt 11 may be a belt track or a metal track, the rotation direction of the first conveyor belt 11 coincides with the extending direction of the carrier 13, a part of the first conveyor belt 11 rotates on the upper side of the carrier 13, another part rotates on the lower side of the carrier 13, and the rotation direction of the first conveyor belt 11 on the upper side of the carrier 13 is opposite to the rotation direction on the lower side of the carrier 13, so that when the first conveyor belt 11 is driven to rotate along the extending direction of the carrier 13, the first conveyor belt 11 drives the test tube holder 200 to move along the extending direction of the carrier 13. It should be noted that, in the tube changing system of the present utility model, the manner of driving the first conveyor belt 11 to rotate relative to the carrier 13 is not limited, for example, a driving mechanism may be mounted at an end of the carrier 13, one end of the first conveyor belt 11 is sleeved on a rotor of the driving mechanism, and the first conveyor belt 11 is driven to rotate relative to the carrier 13 when the rotor of the driving mechanism rotates.

Accordingly, the second conveyor belt 12 may be an endless track, for example, the second conveyor belt 12 may be a belt track or a metal track, the rotation direction of the second conveyor belt 12 is consistent with the extending direction of the conveyor frame 13, a part of the second conveyor belt 12 rotates on the upper side of the conveyor frame 13, another part rotates on the lower side of the conveyor frame 13, and the rotation direction of the second conveyor belt 12 on the upper side of the conveyor frame 13 is opposite to the rotation direction on the lower side of the conveyor frame 13, so that when the second conveyor belt 12 is driven to rotate along the extending direction of the conveyor frame 13, the second conveyor belt 12 drives the test tube holder 200 to move along the extending direction of the conveyor frame 13. It should be noted that the manner of driving the second conveyor belt 12 to rotate relative to the carrier 13 is not limited in the tube changing system of the present utility model, for example, another driving mechanism may be mounted at an end of the carrier 13, one end of the second conveyor belt 12 is sleeved on a rotor of the driving mechanism, and the second conveyor belt 12 is driven to rotate relative to the carrier 13 when the rotor of the driving mechanism rotates.

With continued reference to fig. 1 to 11, in this specific example of the cuvette lane-changing apparatus 100 according to the present utility model, the turntable 21 includes a turntable body 212 and an electromagnetic element 213 provided to the turntable body 212, the radial notch 211 of the turntable 21 is formed in the turntable body 212, wherein the electromagnetic element 213 is capable of causing the radial notch 211 of the turntable 21 to have an electromagnetic field when the electromagnetic element 213 is energized, at which time the turntable 21 is capable of capturing the cuvette holder 200 to allow the cuvette holder 200 to be reliably held in the radial notch 211 of the turntable 21, and at which time the electromagnetic field of the radial notch 211 of the turntable 21 is vanished when the electromagnetic element 213 is energized, at which time the turntable 21 is capable of releasing the cuvette holder 200 to allow the cuvette holder 200 to be transported with the rotation of the first conveyor belt 11 or the second conveyor belt 12.

For example, when the radial notch 211 of the turntable 21 corresponds to the first conveyor belt 11 and faces upstream of the first conveyor belt 11, the encircling section 220 of the test tube holder 200, which is moved by the first conveyor belt 11, is allowed to enter the radial notch 211 of the turntable 21. During rotation of the turntable 21 in a direction in which the radial notch 211 of the turntable 21 is downstream of the first conveyor belt 11, the electromagnetic element 213 is energized to cause the radial notch 211 of the turntable 21 to present an electromagnetic field to allow the turntable 21 to capture the cuvette holder 200, such that, when the turntable 21 rotates to a position in which the radial notch 211 of the turntable 21 corresponds to the downstream of the first conveyor belt 11, the cuvette holder 200 is prevented from escaping the radial notch 211 of the turntable 21 based on magnetic attraction. When the turntable 21 rotates to the downstream of the second conveyor belt 12 corresponding to the radial notch 211 of the turntable 21, the electromagnetic element 213 is powered off to vanish the electromagnetic field of the radial notch 211 of the turntable 21 to allow the turntable 21 to release the test tube holder 200, and the test tube holder 200 moves with the rotation of the second conveyor belt 12 based on friction to be conveyed by the second conveyor belt 12. Through the above-described process, the test tube holder 200 is completed in a lane change operation, that is, the conveying path of the test tube holder 200 is switched from the conveying path formed by the first conveying belt 11 to the conveying path formed by the second conveying belt 12.

Accordingly, when the radial notch 211 of the turntable 21 corresponds to the second conveyor belt 12 and faces upstream of the second conveyor belt 12, the encircling section 220 of the test tube holder 200, which is moved by the second conveyor belt 12, is allowed to enter the radial notch 211 of the turntable 21. During rotation of the turntable 21 in a direction in which the radial notch 211 of the turntable 21 is downstream of the second conveyor belt 12, the electromagnetic element 213 is energized to cause the radial notch 211 of the turntable 21 to present an electromagnetic field to allow the turntable 21 to capture the cuvette holder 200, such that, when the turntable 21 rotates to a position in which the radial notch 211 of the turntable 21 corresponds to the downstream of the second conveyor belt 12, the cuvette holder 200 is prevented from escaping the radial notch 211 of the turntable 21 based on magnetic attraction. When the turntable 21 rotates to the downstream of the turntable 21 corresponding to the first conveyor belt 11, the electromagnetic element 213 is powered off to vanish the electromagnetic field of the radial notch 211 of the turntable 21 to allow the turntable 21 to release the test tube holder 200, and the test tube holder 200 moves with the rotation of the first conveyor belt 11 based on friction to be conveyed by the first conveyor belt 11. Through the above-described process, the test tube holder 200 is completed in a lane change operation, that is, the conveying path of the test tube holder 200 is switched from the conveying path formed by the second conveying belt 12 to the conveying path formed by the first conveying belt 11.

Preferably, the electromagnetic element 213 surrounds the radial notch 211 of the turntable 21, such that when the electromagnetic element 213 is powered, the radial notch 211 of the turntable 21 can present a stable electromagnetic field, so that the turntable 21 can easily capture the cuvette holder 200 and such that the cuvette holder 200 is reliably held in the radial notch 211 of the turntable 21.

Turning now to fig. 3 and 4, the carriage 13 has a frame body through hole 130, wherein the lane changing unit 20 further includes a rotary table driving motor 22 and an electrically conductive slip ring 23, the electrically conductive slip ring 23 includes a fixed portion 231 and a rotating portion 232 rotatably provided to the fixed portion 231, a middle portion of the rotating portion 232 is rotatably provided to the frame body through hole 130 of the carriage 13, a bottom portion of the rotating portion 232 is drivably connected to the rotary table driving motor 22, the rotary table body 212 of the rotary table 21 is fixedly provided to a top portion of the rotating portion 232 to rotatably hold the rotary table 21 above adjacent positions of the first conveyor belt 11 and the second conveyor belt 12 by the rotating portion 232 of the electrically conductive slip ring 23, and the electromagnetic element 213 of the rotary table 21 and the rotating portion 232 are electrically conductive. With such a structure as described above, on the one hand, the conductive slip ring 23 can transmit the power output from the turntable driving motor 22 to the turntable 21 for driving the turntable 21 to rotate above the adjacent positions of the first conveyor belt 11 and the second conveyor belt 12, and on the other hand, the conductive slip ring 23 can supply electric power to the electromagnetic element 213 of the turntable 21 to cause the electromagnetic element 213 to generate an electromagnetic field, so that the radial notch 211 of the turntable 21 can have an electromagnetic field for capturing the test tube holder 200 and reliably holding the test tube holder 200 in the radial notch 211 of the turntable 21.

In addition, with continued reference to fig. 1 to 11, the tube lane-changing apparatus 100 further includes a bracket 30, the top of the bracket 30 is fixedly mounted to the carriage 13, and the driving mechanism 22 and the fixing portion 231 of the conductive slip ring 23 are fixedly mounted to the bottom of the bracket 30, so that the bracket 30 reliably holds the turntable driving motor 22 and the fixing portion 231 of the conductive slip ring 23 to the bottom of the carriage 13 and reliably positions the turntable 21 above the adjacent positions of the first conveyor belt 11 and the second conveyor belt 12 by the rotating portion 232 of the conductive slip ring 23.

Fig. 7 to 11 illustrate a lane changing process of the tube changing system according to the present utility model, in which the tube 300 is mounted on the tube holder 200, for example, the tube 300 may be mounted on the tube holder 200 in such a manner as to be inserted into the tube holder 200, so that the lane changing system performs lane changing of the tube 300 by lane changing of the tube holder 200.

In this specific example of the lane-changing system for test tubes according to the present utility model shown in fig. 7 to 11, the lane-changing process of the lane-changing system for test tubes 200 according to the present utility model will be described by taking the example that the rotation direction of the first conveyor belt 11 and the rotation direction of the second conveyor belt 12 are the same and both rotate from left to right as shown. It will be appreciated that in other examples of the tube lane-changing system of the present utility model, the direction of rotation of the first conveyor belt 11 and the direction of rotation of the second conveyor belt 12 may be opposite.

First, referring to fig. 7 and 8, the radial notch 211 of the turntable 21 corresponds to the first conveyor belt 11 and faces upstream of the first conveyor belt 11, the test tube 300 is inserted into the test tube holder 200, the test tube holder 200 is placed on the upper surface of the first conveyor belt 11, the test tube holder 200 moves with the rotation of the first conveyor belt 11, and the embracing section 220 of the test tube holder 200 can enter the radial notch 211 of the turntable 21. It will be appreciated that after the encircling segment 220 of the test tube holder 200 enters the radial gap 211 of the turntable 21, the turntable 21 can block the test tube holder 200 to prevent the test tube holder 200 from continuing to move with the rotation of the first conveyor belt 11. At this stage, the electromagnetic element 213 of the turntable 21 can be energized to generate an electromagnetic field, at which time the radial notch 211 of the turntable 21 is in the presence of an electromagnetic field for the turntable 21 to capture the cuvette holder 200 and to securely hold the cuvette holder 200 in the radial notch 211 of the turntable 21.

Next, referring to fig. 9, 10 and 11, when the turntable 21 is driven to rotate in a clockwise direction, the turntable 21 can drive the test tube holders 200 to move from a position placed on the upper surface of the first conveyor belt 11 to a position placed on the upper surface of the second conveyor belt 12 through the crossing 1321 of the middle wall 132. And, in this process, the height position of the test tube holder 200 is maintained unchanged to prevent the test tube holder 200 from being toppled over, thereby ensuring the reliability of the lane changing operation. When the radial notch 211 of the turntable 21 corresponds to the second conveyor belt 12 and faces downstream of the second conveyor belt 12, the electromagnetic element 213 of the turntable 21 is powered off to vanish the electromagnetic field of the radial notch 211 of the turntable 21, and at this time, the cuvette holder 200 may move with the rotation of the second conveyor belt 12 based on the friction between the cuvette holder 200 and the second conveyor belt 12.

It will be appreciated that the tube lane changing system of the present utility model may also be configured to change lanes of the tube holders 200 from being transported by the second conveyor belt 12 to being transported by the first conveyor belt 11.

Referring to fig. 12 to 15, a tube slide system according to another preferred embodiment of the present utility model will be disclosed and described in the following description, wherein the tube slide system includes a tube changing device 100A and at least one tube holder 200A, a tube 300A can be inserted into the tube holder 200A, and the tube 300A moves and/or changes the tube as the tube holder 200A moves and/or changes the tube as the tube changing device 100A moves and/or changes the tube.

Specifically, the tube lane-changing apparatus 100A includes a conveying unit 10A, wherein the conveying unit 10A includes a first conveying belt 11A, a second conveying belt 12A, and a conveying frame 13A, the first conveying belt 11A and the second conveying belt 12A are rotatably mounted to the conveying frame 13A, respectively, and at least a portion of the first conveying belt 11A and at least a portion of the second conveying belt 12A are adjacent.

The tube lane-changing apparatus 100A further comprises a lane-changing unit 20A, the lane-changing unit 20A comprising a turntable 21A, a magnet 25A and a magnet driving assembly 26A, wherein the turntable 21A has a radial notch 211A, the turntable 21A is rotatably disposed above adjacent positions of the first conveyor belt 11A and the second conveyor belt 12A to allow the radial notch 211A of the turntable 21A to rotate at a position corresponding to the first conveyor belt 11A to a position corresponding to the second conveyor belt 12A, wherein the magnet 25A is adjacent to the radial notch 211A of the turntable 21A, and the magnet 25A is drivably connected to the magnet driving assembly 26A, the magnet driving assembly 26A is configured to be able to change a position of the magnet 25A relative to the radial notch 211A of the turntable 21A, a magnetic field strength at the radial notch 211A for adjusting the turntable 21A to reliably hold the turntable 21A in place the radial notch 211A to the tube holder 200A in the radial notch 200A or the tube holder 200A to be able to be rotatably held in the radial notch 200A with the turntable holder 200A.

It will be appreciated that when the magnet drive assembly 26A moves the magnet 25A to a position close to the radial notch 211A of the turntable 21A, the magnetic field strength at the radial notch 211A of the turntable 21A is enhanced, and at this time, the magnet 25A can reliably hold the cuvette holder 200A in the radial notch 211A of the turntable 21A based on the magnetic attraction force attracting the magnetic element 210A of the cuvette holder 200A. Accordingly, when the magnet driving assembly 26A moves the magnet 25A to a position away from the radial notch 211A of the turntable 21A, the magnetic field strength at the radial notch 211A of the turntable 21A is weakened, and at this time, the magnet 25A cannot attract the magnetic element 210A of the cuvette holder 200A to allow the cuvette holder 200A to be released from the radial notch 211A of the turntable 21A.

Preferably, the magnet 25A has a magnet notch 251A, and the position of the magnet notch 25A of the magnet 25A corresponds to the position of the radial notch 211A of the turntable 21A, such that when the magnet 25A is moved by the magnet driving assembly 26A to a position close to the radial notch 211A of the turntable 21A, the magnet 25A makes the magnetic field strength at the radial notch 211A of the turntable 21A stronger for stably sucking the magnetic element 210A of the cuvette holder 200A to reliably hold the cuvette holder 200A at the radial notch 211A of the turntable 21A.

In the tube changing system of the present utility model, the first conveyor belt 11A drives the tube holder 200A to transfer based on friction force when rotating, that is, the tube holder 200A can be directly placed on the upper surface of the first conveyor belt 11A to allow the tube holder 200A to be located above the first conveyor belt 11A, and the tube holder 200A can be moved by the first conveyor belt 11A based on friction force generated between the tube holder 200A and the first conveyor belt 11A as the first conveyor belt 11A rotates. Accordingly, the second conveyor belt 12A drives the test tube holder 200A to transfer based on friction force when rotating, that is, the test tube holder 200A can be directly placed on the upper surface of the second conveyor belt 12A to allow the test tube holder 200A to be located above the second conveyor belt 12A, and the test tube holder 200A can be driven to move by the second conveyor belt 12A based on friction force generated between the test tube holder 200A and the second conveyor belt 12A along with the rotation of the second conveyor belt 12A.

It is understood that the first conveyor belt 11A may be an endless track, for example, the first conveyor belt 11A may be a belt track or a metal track, the rotation direction of the first conveyor belt 11A coincides with the extending direction of the rack 13A, a part of the first conveyor belt 11A rotates on the upper side of the rack 13A, another part rotates on the lower side of the rack 13A, and the rotation direction of the first conveyor belt 11A on the upper side of the rack 13A is opposite to the rotation direction on the lower side of the rack 13A, so that the first conveyor belt 11A drives the cuvette holder 200A to move along the extending direction of the rack 13A when the first conveyor belt 11A is driven to rotate along the extending direction of the rack 13A. It should be noted that, in the tube changing system of the present utility model, the manner of driving the first conveyor belt 11A to rotate relative to the carrier 13A is not limited, for example, a driving mechanism may be mounted at an end of the carrier 13A, one end of the first conveyor belt 11A is sleeved on a rotor of the driving mechanism, and the first conveyor belt 11A is driven to rotate relative to the carrier 13A when the rotor of the driving mechanism rotates.

Accordingly, the second conveyor belt 12A may be an endless track, for example, the second conveyor belt 12A may be a belt track or a metal track, the rotation direction of the second conveyor belt 12A coincides with the extending direction of the rack 13A, a part of the second conveyor belt 12A rotates on the upper side of the rack 13A, another part rotates on the lower side of the rack 13A, and the rotation direction of the second conveyor belt 12A on the upper side of the rack 13A is opposite to the rotation direction on the lower side of the rack 13A, so that the second conveyor belt 12A drives the test tube holder 200A to move along the extending direction of the rack 13A when the second conveyor belt 12A is driven to rotate along the extending direction of the rack 13A. It should be noted that, in the tube changing system of the present utility model, the manner of driving the second conveyor belt 12A to rotate relative to the carrier 13A is not limited, for example, another driving mechanism may be mounted at an end of the carrier 13A, one end of the second conveyor belt 12A is sleeved on a rotor of the driving mechanism, and the second conveyor belt 12A is driven to rotate relative to the carrier 13A when the rotor of the driving mechanism rotates.

When the radial notch 211A of the turntable 21A corresponds to the first conveyor belt 11A and faces upstream of the first conveyor belt 11A, the encircling section 220A of the test tube holder 200A moved by the first conveyor belt 11A is allowed to enter the radial notch 211A of the turntable 21A. During rotation of the turntable 21A in a direction in which the radial notch 211A of the turntable 21A is downstream of the first conveyor belt 11A, the magnet 25A attracts the magnetic element 210A of the test tube holder 200A to allow the embracing section 220A of the test tube holder 200A to be securely held at the radial notch 211A of the turntable 21A, such that the test tube holder 200A is prevented from being disengaged from the radial notch 211A of the turntable 21A based on a magnetic attraction force between the magnet 25A and the magnetic element 210A of the test tube holder 200A when the turntable 21A rotates to a position in which the radial notch 211A of the turntable 21A corresponds to the downstream of the first conveyor belt 211. When the turntable 21A rotates to the position where the radial notch 211A of the turntable 21A corresponds to the downstream of the second conveyor belt 12A, the magnet driving assembly 26A drives the magnet 25A away from the radial notch 211A of the turntable 21A so that the magnetic field at the radial notch 211A of the turntable 21A is weakened or vanished, and the test tube holder 200A moves with the rotation of the second conveyor belt 12A based on the frictional force to be conveyed by the second conveyor belt 12A. Through the above-described process, the tube holder 200A is completed in a lane change operation, that is, the conveying path of the tube holder 200A is switched from the conveying path formed by the first conveying belt 11A to the conveying path formed by the second conveying belt 12A.

Accordingly, when the radial notch 21 of the turntable 21A corresponds to the second conveyor belt 12A and faces upstream of the second conveyor belt 12A, the encircling section 220A of the test tube holder 200A moved by the second conveyor belt 12A is allowed to enter the radial notch 211A of the turntable 21A. During rotation of the turntable 21A in a direction in which the radial notch 211A of the turntable 21A is downstream of the second conveyor belt 12A, the magnet 25A attracts the magnetic element 210A of the cuvette holder 200A to allow the embracing section 220A of the cuvette holder 200A to be securely held at the radial notch 211A of the turntable 21A, such that the cuvette holder 200A is prevented from escaping from the radial notch 211A of the turntable 21A based on a magnetic attraction between the magnet 25A and the magnetic element 210A of the cuvette holder 200A when the turntable 21A rotates to a position in which the radial notch 211A of the turntable 21A corresponds to a position downstream of the second conveyor belt 12A. When the turntable 21A rotates to the position where the radial notch 211A of the turntable 21A corresponds to the position downstream of the first conveyor belt 11A, the magnet driving assembly 26A drives the magnet 25A away from the radial notch 211A of the turntable 21A so that the magnetic field at the radial notch 211A of the turntable 21A is weakened or vanished, and the test tube holder 200A moves with the rotation of the first conveyor belt 11A based on the frictional force to be conveyed by the first conveyor belt 11A. Through the above-described process, the tube holder 200A is completed in a lane change operation, that is, the conveying path of the tube holder 200A is switched from the conveying path formed by the second conveying belt 12A to the conveying path formed by the first conveying belt 11A.

The upper side of the first conveyor belt 11A is rotatably disposed in the first conveying groove 134A of the conveyor frame 13A to sink the upper surface of the first conveyor belt 11A, so that the bottom end of the test tube holder 200A disposed on the upper surface of the first conveyor belt 11A is positioned in the first conveying groove 134A of the conveyor frame 13A, and thus the conveyor frame 13A can prevent the test tube holder 200A from being separated from the first conveyor belt 11A in the lateral direction (the lateral direction is perpendicular to the rotation direction of the first conveyor belt 11A) or from being inclined toward the lateral direction of the first conveyor belt 11A, when the first conveyor belt 11A rotates to move the test tube holder 200A, to allow the first conveyor belt 11A to stably convey the test tube holder 200A.

The upper side of the second conveyor belt 12A is rotatably disposed in the second conveying groove 135A of the conveying frame 13A to sink the upper surface of the second conveyor belt 12A, so that the bottom end of the test tube holder 200A disposed on the upper surface of the second conveyor belt 12A is positioned in the second conveying groove 135A of the conveying frame 13A, and the conveying frame 13A can prevent the test tube holder 200A from being separated from the second conveyor belt 12A in the lateral direction (the lateral direction is perpendicular to the rotation direction of the second conveyor belt 12A) or from being inclined toward the lateral direction of the second conveyor belt 12A, thereby allowing the first conveyor belt 11A to stably convey the test tube holder 200A when the second conveyor belt 12A rotates to move the test tube holder 200A.

To achieve the lane-changing operation of the test tube holder 200A, the middle wall 132A has a lane-changing hole 1321A, and the lane-changing hole 1321A communicates with the first conveying groove 134A and the second conveying groove 135A, wherein when the radial notch 211A of the turntable 21A rotates from a position corresponding to the first conveying belt 11A to a position corresponding to the second conveying belt 12A, the lane-changing hole 1321A of the middle wall 132A and the radial notch 211A of the turntable 21A can be aligned in a height direction to allow the test tube holder 200A to move from the upper surface of the first conveying belt 11A to the upper surface of the second conveying belt 12A through the lane-changing hole 1321A of the middle wall 132A.

One of the side of the top of the middle wall 132A and the top of one of the outer walls 133A is provided with a first stopper 136A protruding toward the first conveying groove 134A of the conveying rack 13A, and when the test tube holder 200A is placed on the upper surface of the first conveying belt 11A, the first stopper 136A of the conveying rack 13A extends to a catch groove 230A of the test tube holder 200A, so that when the first conveying belt 11A moves with the test tube holder 200A, the conveying rack 13A can not only prevent the test tube holder 200A from being separated from the first conveying belt 11A in the lateral direction or from being inclined toward the lateral direction of the first conveying belt 11A, but also prevent the test tube holder 200A from being inclined toward the longitudinal direction (the longitudinal direction and the rotational direction of the first conveying belt 11A are coincident) of the first conveying belt 11A, so as to allow the first conveying belt 11A to stably convey the test tube holder 200A. Preferably, the top of the middle wall block 132A and the top of one of the outer wall blocks 133A are provided with the first limiting strips 136A, so that when the test tube holder 200A is placed on the upper surface of the first conveyor belt 11A, the two first limiting strips 136A of the conveying frame 13A can extend to the clamping grooves 230A of the test tube holder 200A at opposite sides of the test tube holder 200A.

One of the other side of the top of the middle wall block 132A and the top of the other outer wall block 133A is provided with a second limit bar 137A protruding toward the second conveying groove 135A of the conveying rack 13A, and when the test tube holder 200A is placed on the upper surface of the second conveying belt 12A, the second limit bar 137A of the conveying rack 13A extends to the catch groove 230A of the test tube holder 200A, so that when the second conveying belt 12A moves with the test tube holder 200A, the conveying rack 13A can not only prevent the test tube holder 200A from falling off the second conveying belt 12A in the lateral direction or from tilting toward the lateral direction of the second conveying belt 12A, but also prevent the test tube holder 200A from tilting toward the longitudinal direction of the second conveying belt 12A, so as to allow the second conveying belt 12A to stably convey the test tube holder 200A. Preferably, the top of the middle wall block 132A and the top of one of the outer wall blocks 133A are provided with the second limiting bars 137A, so that when the test tube holder 200A is placed on the upper surface of the second conveyor belt 12A, the two second limiting bars 137A of the conveying rack 13A can extend to the clamping grooves 230A of the test tube holder 200A at opposite sides of the test tube holder 200A.

With continued reference to fig. 12-14, the turntable 21A has a recess 214A, the recess 214A is in communication with the radial gap 211A, wherein the magnet 25A is movably disposed in the recess 214A of the turntable 21A, in such a way that the tube changing device 100A can sink the magnet 25A, can lower the height of the magnet 25A protruding from the top of the turntable 21A, and even the top of the magnet 25A can be flush with the top of the turntable 21A, or the top of the magnet 25A can be slightly lower than the top of the turntable 21A.

It will be appreciated that when the magnet drive motor 261A drives the magnet 25A in the height direction toward the radial gap 211A near the turntable 21A by the power steering element 262A, the magnet 25A gives a stronger magnetic field strength at the radial gap 211A of the turntable 21A. Accordingly, when the magnet driving motor 261A drives the magnet 25A to move in the height direction toward the radial notch 211A away from the turntable 21A by the power steering element 262A, the magnet 25A causes the turntable 21A to have a weaker magnetic field strength at the radial notch 211A.

Further, with continued reference to fig. 12 to 14, the turntable 21A has a guide groove 215A opened upward, the guide groove 215A communicates with the recess 214A, wherein one end portion of the power steering member 262A is fixedly connected to the magnet 25A, the other end portion has a screw hole 2621A, the screw output shaft 2611 of the magnet driving motor 261A is rotatably mounted to the screw hole 2621A of the power steering member 262A, and the magnet driving motor 261A is disposed above the turntable 21A, the power steering member 262A is disposed movably up and down to the guide groove 215A of the turntable 21A, so that the power steering member 262A can convert the rotational movement of the magnet driving motor 261A into the radial movement of the magnet 25A for driving the magnet 25A to generate the movement relative to the turntable 21A in the height direction.

It should be noted that, in the tube lane changing system of the present utility model, the manner in which the magnet driving motor 261A is disposed above the turntable 21A is not limited, for example, the tube lane changing device 100A further includes a mounting frame 40A, the mounting frame 40A is mounted above the turntable 21A, the magnet driving motor 261A is mounted on the mounting frame 40A, and the mounting frame 40A is used to dispose the magnet driving motor 261A above the turntable 21A.

Further, the magnet 25A has a guide hole 252A, the turntable 21A has a guide post 216A, and the guide post 216A of the turntable 21A extends to the guide hole 252A of the magnet 25A, wherein the guide post 216A of the turntable 21A is used to guide a moving direction of the magnet 25A when the magnet driving motor 261A drives the magnet 25A to move by the power reversing element 262A. That is, the guide posts 216A of the turntable 21A serve to limit the movement direction of the magnet 25A to the height direction, preventing the magnet 25A from being activated in the horizontal direction, thereby improving the reliability of the tube lane changing apparatus 100A.

Fig. 15 to 17 show a modified example of the tube changing system according to the above preferred embodiment of the present utility model, unlike the tube changing system shown in fig. 12 to 14, in this specific example of the tube changing system shown in fig. 15 to 17, the magnet driving motor 261A drives the magnet 25A to move in the horizontal direction by the power reversing element 262A to change the position of the magnet 25A with respect to the radial notch 211A of the turntable 21A for adjusting the magnetic field strength at the radial notch 211A of the turntable 21A.

Specifically, the power steering element 262A is movably disposed horizontally in the guide groove 215A of the turntable 21A, and when the magnet driving motor 261A drives the power steering element 262A to move in the horizontal direction, the power steering element 262A drives the magnet 25A to move in the horizontal direction, thereby changing the position of the magnet 25A relative to the radial notch 211A of the turntable 21A for adjusting the magnetic field intensity at the radial notch 211A of the turntable 21A.

The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model.
