[0067] See also Figure 1-7 As shown, the present application provides a biological sample transmission module, including a first track 11, a second track 12 and a lever 20. The first track 11 and the second track 12 are both loop tracks, and the second track 12 is located on the inner side of the first track 11. The first track 11 and the second track 12 can both be used for the carrier 100 to circulate in the same direction. The carrier 100 can be used to carry a sample container containing a sample. The lever 20 can be used to keep the first track 11 and the second track 12 independently of each other for biological sample transportation, and the lever 20 can also be used to block the first track 11 so that the sample on the first track 11 is changed to the second track 12, or to block the second track 12 so that the sample on the second track 12 is changed to the first track 11.

[0068] Furthermore, the first track 11 and the second track 12 are provided with a lane-changing opening 131 for the vehicle 100 to pass through, and the lever 20 is provided at the lane-changing opening 131 . The lever 20 can be rotatably arranged and can open or close the lane-changing opening 131 .

[0069] The lane change gate 131 can cooperate with the lever 20 to change the vehicle 100 on the first track 11 to the second track 12 , and can cooperate with the lever 20 to change the vehicle 100 on the second track 12 to the first track 11 .

[0070] Furthermore, the lever 20 has a first working position, a second working position and a third working position.

[0071] When the lever 20 is located at the first working position, the lever 20 closes the lane change gate 131. At this time, the first track 11 and the second track 12 are independent of each other, and the carrier 100 on the first track 11 can only move in a cycle independently along the first track 11, and the carrier 100 on the second track 12 can only move in a cycle independently along the second track 12.

[0072] When the lever 20 is located at the second working position, the lever 20 deflects toward the first track 11 to open the lane-changing opening 131 and block the first track 11. At this time, the vehicle 100 on the first track 11 can change lanes to the second track 12 through the lane-changing opening 131, thereby achieving the lane-changing of the vehicle 100 on the first track 11 to the second track 12 at the lane-changing opening 131.

[0073] When the lever 20 is located at the third working position, the lever 20 deflects toward the second track 12 to open the lane-changing opening 131 and block the second track 12. At this time, the vehicle 100 on the second track 12 can change lanes to the first track 11 through the lane-changing opening 131, thereby achieving the lane-changing of the vehicle 100 on the second track 12 to the first track 11 at the lane-changing opening 131.

[0074] In this embodiment, by setting the first track 11 and the second track 12 as loop tracks that can independently provide the carrier 100 with circular motion, and making the carrier 100 circularly move in the same direction on the first track 11 and the second track 12, and by setting the shift lever 20 at the lane change intersection 131 between the first track 11 and the second track 12, the first track 11 and the second track 12 can be controlled in different working positions so that the first track 11 and the second track 12 can independently provide the carrier 100 with circular motion in the same direction, and can also flexibly change lanes at the same lane change intersection 131.

[0075] Furthermore, by arranging the lever 20 to be switchable between the second working position and the third working position, the carrier 100 on the first track 11 can change lanes to the second track 12, or change lanes from the second track 12 to the first track 11, all at the same lane change intersection 131, thereby realizing flexible lane changes at the same lane change intersection 131 on the inner and outer double tracks consisting of the first track 11 and the second track 12.

[0076] Therefore, in this embodiment, only a simple structure is used to achieve the flexible lane change of the carrier 100 between the first track 11 and the second track 12, as well as the unidirectional circulation on the first track 11 or the second track 12, thereby improving the transmission efficiency of the carrier 100 and / or the sample.

[0077] Furthermore, the first track 11 and the second track 12 are separated by a separation plate 13 .

[0078] In one embodiment, the lever 20 is rotatably disposed in the lane-changing opening 131. That is, the lever 20 is sunk in the lane-changing opening 131, so that the lever 20 does not protrude from the partition plate 13 in the vertical direction.

[0079] In another embodiment, the lever 20 can be rotatably disposed on the partition plate 13, and when the lever 20 is in the first position, the lane change intersection 131 can be at least partially blocked, thereby preventing the carrier 100 on the first track 11 or the second track 12 from passing through the lane change intersection 131.

[0080] Furthermore, the shifting rod 20 is connected to the first driving device via a first rotating shaft, and the shifting rod 20 can be switched among the first working position, the second working position and the third working position under the driving of the first driving device.

[0081] Furthermore, the lever 20 includes a first end 21 and a second end 22 that are arranged opposite to each other. The first end 21 is rotatably arranged between the first track 11 and the second track 12, and the second end 22 is rotatable relative to the first end 21, that is, the second end 22 is a free end. The first end 21 can be rotatably arranged in the lane change intersection 131, or can be rotatably arranged on the partition plate 13.

[0082] When the lever 20 is in the first working position, the lever 20 closes the lane change gate 131 to separate the first track 11 and the second track 12, and the lever 20 does not interfere with the first track 11 and the second track 12. At this time, the first track 11 and the second track 12 are two independent tracks, and the carrier 100 on the first track 11 can only move on the first track 11, and the carrier 100 on the second track 12 can only move on the second track 12.

[0083] When the lever 20 is in the second working position, the second end 22 deflects toward the first track 11 to block the first track 11 and open the lane-changing opening 131. At this time, the lever 20 is in an inclined state and blocks the first track 11. When the vehicle 100 on the first track 11 moves along the first track 11 and contacts the lever 20, the vehicle 100 moves toward the lane-changing opening 131 along the lever 20 under the blocking and guiding action of the lever 20 in the inclined state, and finally passes through the lane-changing opening 131 and enters the second track 12, thereby realizing the lane change from the first track 11 to the second track 12.

[0084] When the lever 20 is in the third working position, the second end 22 deflects toward the second track 12 to block the second track 12 and open the lane-changing opening 131. At this time, the lever 20 is blocked at the second track 12 in an inclined state, and the carrier 100 on the second track 12 moves along the second track 12 and contacts the lever 20. Under the blocking and guiding action of the lever 20 in the inclined state, the carrier 100 moves along the lever 20 toward the lane-changing opening 131, and finally passes through the lane-changing opening 131 to enter the first track 11, thereby realizing the lane change from the second track 12 to the first track 11.

[0085] Furthermore, the biological sample transmission module comprises a first baffle plate 15 and a second baffle plate 16. The partition plate 13 is located between the first baffle plate 15 and the second baffle plate 16.

[0086] The partition plate 13 and the first baffle plate 15 are spaced a certain distance apart to form the first track 11. The partition plate 13 and the second baffle plate 16 are spaced a certain distance apart to form the second track 12.

[0087] Furthermore, the biological sample transmission module further includes a mounting plate 14, and the first baffle plate 15, the second baffle plate 16 and the partition plate 13 are respectively arranged on the mounting plate 14, so that the first baffle plate 15, the second baffle plate 16 and the partition plate 13 can be supported and fixed by the mounting plate 14. The first driving device can also be arranged on the mounting plate 14.

[0088] Furthermore, a first limiting notch 151 is provided on a side of the first baffle plate 15 close to the partition plate 13. When the lever 20 is in the second working position, the second end 22 is located in the first limiting notch 151. By providing the first limiting notch 151 to limit and support the second end 22, when the lever 20 in the second working position is impacted by the vehicle 100 when changing lanes, the vehicle 100 changing lanes can be guided and limited more stably through the support of the first baffle plate 15 corresponding to the first limiting notch 151.

[0089] A second limiting notch 161 is provided on the side of the second baffle plate 16 close to the partition plate 13. When the lever 20 is in the third working position, the second end 22 is located in the second limiting notch 161. By providing the second limiting notch 161 to limit and support the second end 22, when the lever 20 in the third working position is impacted by the vehicle 100 when changing lanes, the vehicle 100 changing lanes can be guided and limited more stably through the support of the second baffle plate 16 corresponding to the second limiting notch 161.

[0090] Furthermore, the biological sample transmission module further includes a first stopper 30 and a second stopper 40. The first stopper 30 and the second stopper 40 are respectively arranged upstream of the lever 20. The first stopper 30 can be used to stop or release the carrier 100 on the first track 11. The second stopper 40 can be used to stop or release the carrier 100 on the second track 12.

[0091] In one embodiment, the first stopper 30 is rotatably disposed on the first baffle plate 15 . The second stopper 40 is rotatably disposed on the second baffle plate 16 .

[0092] In another embodiment, the first baffle plate 15 is provided with a first mounting hole, and the first stopper 30 is rotatably disposed in the first mounting hole, so that the first stopper 30 sinks into the first baffle plate 15 .

[0093] The second baffle plate 16 is provided with a second mounting hole. The second stopper 40 is rotatably disposed in the second mounting hole, so that the second stopper 40 sinks into the second baffle plate 16 .

[0094] Further, in one embodiment, the first limiting notch 151 is spaced a certain distance from the first mounting hole so that the first limiting notch 151 is not connected to the first mounting hole. The second limiting notch 161 is spaced a certain distance from the second mounting hole so that the second limiting notch 161 is not connected to the second mounting hole.

[0095] In another embodiment, the first limiting notch 151 is interconnected with the first mounting hole to reduce the distance between the lever 20 and the first stopper 30. The second limiting notch 161 is interconnected with the second mounting hole to reduce the distance between the lever 20 and the second stopper 40.

[0096] In one embodiment, the first stopper 30 is connected to the second driving device via a second rotating shaft. Under the drive of the second driving device, the first stopper 30 can rotate to release the carriers 100 on the first track 11 one by one, or the first stopper 30 stops rotating to stop the carriers 100 on the first track 11 that have not passed the first stopper 30.

[0097] The second stopper 40 is connected to the third driving device via a third rotating shaft. Under the drive of the third driving device, the second stopper 40 can rotate to release the carriers 100 on the second track 12 one by one, or the second stopper 40 stops rotating to stop the carriers 100 on the second track 12 that have not passed the second stopper 40.

[0098] Further, in one embodiment, the first stopper 30 is a disc-shaped structure, and a plurality of first avoidance grooves 31 are formed on the outer edge structure of the first stopper 30, and a first stopper 32 is provided between two adjacent first avoidance grooves 31. The first stopper 30 rotates to allow the carrier 100 entering the first avoidance groove 31 to pass over the first stopper 30. The first stopper 30 stops rotating to allow the first stopper 32 to stop the carrier 100 that has not passed over the first stopper 30.

[0099] In one embodiment, the first stopper 30 is structured to form six first avoidance grooves 31 and six first stop portions 32. Each of the first avoidance grooves 31 can avoid the carrier 100 on the first track 11 under the rotation of the first stopper 30 so that the carrier 100 passes over the first stopper 30, and each of the first stop portions 32 can stop any of the carriers 100 on the first track 11. It should be noted that when the first stopper 30 stops rotating, even if any of the carriers 100 enters any of the first avoidance grooves 31 but has not passed over the first stopper 30, the carrier 100 will be stopped by the first stopper 30.

[0100] The second stopper 40 has the same structure as the first stopper 30. The second stopper 40 is a disc-shaped structure, and the second stopper 40 is configured to form a second avoidance groove 41, with a second stop portion 42 between two adjacent second avoidance grooves 41. The second stopper 40 rotates so that the carrier 100 entering the second avoidance groove 41 can pass over the second stopper 40, and the second stopper 40 stops rotating so that the second stop portion 42 stops the carrier 100 that has not passed over the second stopper 40.

[0101] In one embodiment, the first stopper 30 is configured to have six second avoidance grooves 41 and six second stop portions 42. Any of the second avoidance grooves 41 can avoid any of the carriers 100 on the second track 12 when the second stopper 40 rotates, and any of the second stop portions 42 can also stop any of the carriers 100 on the second track 12 when the second stopper 40 stops rotating.

[0102] Furthermore, the first stopper 30 and the second stopper 40 are arranged opposite to each other along the moving direction of the carrier 100 , and the rotation center points of the first stopper 30 , the second stopper 40 and the lever 20 respectively form an isosceles triangle.

[0103] The lever 20 switches between the first working position, the second working position and the third working position at the first rotation center; the first stopper 30 rotates at the second rotation center to release the carrier 100 on the first track 11, or stops rotating to stop the carrier 100 on the first track 11; the second stopper 40 rotates at the third rotation center to release the carrier 100 on the second track 12, or stops rotating to stop the carrier 100 on the second track 12. The first rotation center, the second rotation center and the third rotation center are connected to form the isosceles triangle.

[0104] The biological sample transmission module further includes a first sensing component and a second sensing component. The first sensing component is located upstream of the lever 20, and the first sensing component includes a first sensing device 51 and a second sensing device 52. The first sensing device 51 is used to sense the carrier 100 located upstream of the lever 20 on the first track 11; the second sensing device 52 is used to sense the carrier 100 located upstream of the lever 20 on the second track 12.

[0105] The second sensing assembly is located downstream of the lever 20, and includes a third sensing device 53 and a fourth sensing device 54. The third sensing device 53 is used to sense the vehicle 100 on the first track 11; the fourth sensing device 54 is used to sense the vehicle 100 on the second track 12.

[0106] Further, the first sensing device 51 is disposed at the first stopper 30 , and the second sensing device 52 is disposed at the second stopper 40 .

[0107] In this embodiment, when at least two vehicles 100 move along the same motion path and pass through the shifting rod 20 , at least two vehicles 100 have the following four motion path situations.

[0108] The first situation is that at least two carriers 100 are running along the first track 11. In this situation, when the previous carrier 100 of the first stopper 30 is sensed by the first sensing device 51 but before being sensed by the third sensing device 53, the first stopper 30 stops the next carrier 100. In this process, the previous carrier 100 is only sensed by the first sensing device 51 but has not yet been sensed by the third sensing device 53.

[0109] When the carrier 100 preceding the first stopper 30 sensed by the first sensing device 51 is sensed by the third sensing device 53, the first stopper 30 releases the next carrier 100. In this process, the preceding carrier 100 needs to be sensed by the first sensing device 51 and the third sensing device 53 in sequence before the first stopper 30 can release the next carrier 100 sensed by the first sensing device 51.

[0110] The second situation is that at least two carriers 100 are running along the second track 12. In this situation, when the previous carrier 100 of the second stopper 40 is sensed by the second sensing device 52 but before being sensed by the fourth sensing device 54, the second stopper 40 stops the next carrier 100. In this process, the previous carrier 100 is only sensed by the second sensing device 52 but has not yet been sensed by the fourth sensing device 54.

[0111] When the carrier 100 preceding the second stopper 40 sensed by the second sensing device 52 is sensed by the fourth sensing device 54, the second stopper 40 releases the next carrier 100. In this process, the preceding carrier 100 needs to be sensed by the second sensing device 52 and the fourth sensing device 54 in sequence before the second stopper 40 can release the next carrier 100 sensed by the second sensing device 52.

[0112] The third situation is that at least two vehicles 100 change lanes from the first track 11 to the second track 12. In this situation, when the previous vehicle 100 of the first stopper 30 is sensed by the first sensing device 51 but before being sensed by the fourth sensing device 54, the first stopper 30 stops the next vehicle 100. In this process, the previous vehicle 100 is only sensed by the first sensing device 51 but has not yet been sensed by the fourth sensing device 54.

[0113] When the carrier 100 preceding the first stopper 30 sensed by the first sensing device 51 is sensed by the fourth sensing device 54, the first stopper 30 releases the next carrier 100. In this process, the preceding carrier 100 needs to be sensed by the first sensing device 51 and the fourth sensing device 54 in sequence before the first stopper 30 can release the next carrier 100 sensed by the first sensing device 51.

[0114] The fourth situation is that at least two carriers 100 are running along the second track 12 and then the first track 11. In this situation, when the previous carrier 100 of the second stopper 40 is sensed by the second sensing device 52 but before being sensed by the third sensing device 53, the second stopper 40 stops the next carrier 100. In this process, the previous carrier 100 is only sensed by the second sensing device 52 but has not yet been sensed by the third sensing device 53.

[0115] When the carrier 100 preceding the second stopper 40 sensed by the second sensing device 52 is sensed by the third sensing device 53, the second stopper 40 releases the next carrier 100. In this process, the preceding carrier 100 needs to be sensed by the second sensing device 52 and the third sensing device 53 in sequence before the second stopper 40 can release the next carrier 100 sensed by the second sensing device 52.

[0116] Furthermore, when the next vehicle 100 needs to change lanes, and after the previous vehicle 100 is sensed by any sensing device in the second sensing component, the lever 20 can be switched from the current working position to the working position required for the next vehicle 100 to change lanes, and after the lever 20 completes the working position switching, the first stopper 30 or the second stopper 40 releases the next vehicle 100.

[0117] When the next vehicle 100 needs to change lanes and before the previous vehicle 100 is sensed by any sensing device in the second sensing assembly, the lever 20 cannot switch the working position.

[0118] Furthermore, when at least two vehicles 100 located upstream of the lever 20 and on the same track need to move along different motion paths and pass through the lever 20 , at least two vehicles 100 have the following two motion path situations.

[0119] The first situation is that at least two vehicles 100 are moving on the first track 11 upstream of the lever 20 , and the first vehicle 100 needs to go straight along the first track 11 , while the next vehicle 100 needs to change lanes to the second track 12 at the lane change intersection 131 .

[0120] In this case, before the previous carrier 100 passes over the first stopper 30, the lever 20 is in the first working position, and before the previous carrier 100 is sensed by the third sensing device 53, the lever 20 cannot be switched from the first working position to the second working position. Furthermore, the first stopper 30 cannot release the next carrier 100.

[0121] After the previous carrier 100 moves along the first track 11 and is sensed by the third sensing device 53, the lever 20 can be switched from the first working position to the second working position, and then the first stopper 30 can release the next carrier 100. After the next carrier 100 moves along the first track 11 and is blocked and guided by the lever 20, it changes lanes to the second track 12 through the lane change intersection 131.

[0122] Furthermore, for the other carriers 100 located upstream of the next carrier 100 on the first track 11, if it is necessary to change lanes from the first track 11 to the second track 12, the next carrier 100 needs to be sensed by the fourth sensing device 54 before being released by the first stopper 30; if it is necessary to go straight along the first track 11, the next carrier 100 needs to be sensed by the fourth sensing device 54, and the lever 20 needs to be switched from the second working position to the first working position before being released by the first stopper 30.

[0123] The second situation is that at least two of the vehicles 100 move on the second track 12 upstream of the lever 20 , and the first vehicle 100 needs to go straight along the second track 12 , while the next vehicle 100 needs to change lanes to the first track 11 at the lane change intersection 131 .

[0124] In this case, before the previous carrier 100 passes over the second stopper 40, the lever 20 is in the first working position, and before the previous carrier 100 is sensed by the fourth sensing device 54, the lever 20 cannot be switched from the first working position to the third working position. Furthermore, the second stopper 40 cannot release the next carrier 100.

[0125] After the previous carrier 100 moves along the second track 12 and is sensed by the fourth sensing device 54, the lever 20 can be switched from the first working position to the third working position, and then the second stopper 40 can release the next carrier 100. After the next carrier 100 moves along the second track 12 and is blocked and guided by the lever 20, it changes lanes to the first track 11 through the lane change intersection 131.

[0126] Furthermore, for the other carriers 100 located upstream of the next carrier 100 on the second track 12, if it is necessary to change lanes from the second track 12 to the first track 11, the next carrier 100 needs to be sensed by the third sensing device 53 before it can be released by the second stopper 40; if it is necessary to go straight along the second track 12, the next carrier 100 needs to be sensed by the third sensing device 53, and the lever 20 needs to be switched from the third working position to the first working position before it can be released by the second stopper 40.

[0127] It should be noted that, in the present application, lane changing includes the following situations.

[0128] In the first case, the first carrier 100 goes straight along the first track 11, and the second carrier 100 changes lanes from the first track 11 to the second track 12, and the second carrier 100 changes lanes.

[0129] In the second situation, the first carrier 100 goes straight along the second track 12, and the second carrier 100 changes lanes from the second track 12 to the first track 11, and the second carrier 100 changes lanes.

[0130] In the third case, the first carrier 100 changes lanes from the first track 11 to the second track 12, and the second carrier 100 goes straight along the first track 11, then the second carrier 100 changes lanes relative to the first carrier 100.

[0131] In a fourth situation, the first carrier 100 changes lanes from the second track 12 to the first track 11, and the second carrier 100 goes straight along the second track 12, and the second carrier 100 changes lanes relative to the first carrier 100.

[0132] Furthermore, in one embodiment, the first sensing device 51, the second sensing device 52, the third sensing device 53 and the fourth sensing device 54 are all light sensors, and the first sensing device 51, the second sensing device 52, the third sensing device 53 and the fourth sensing device 54 respectively have the function of emitting a detection light source and receiving a corresponding reflected light source.

[0133] The biological sample transmission module includes a first reflective member 61 , which is disposed on the partition plate 13 and has a first reflective surface 611 corresponding to the first sensing device 51 and a second reflective surface 612 corresponding to the second sensing device 52 .

[0134] When the detection light source emitted by the first sensing device 51 is reflected by the first reflective surface 611, a corresponding first reflected light signal will be formed. The first sensing device 51 will receive the first reflected light signal and determine based on the reflected light signal that there is no carrier 100 at the corresponding first track 11 (i.e., the first stopper 30).

[0135] When the detection signal emitted by the first sensing device 51 is not reflected by the first reflective surface 611 but is reflected by the carrier 100 to form a corresponding second reflected light signal, the first sensing device 51 will receive the second reflected light signal and determine that the corresponding first track 11 (i.e., the first stopper 30) has the carrier 100 based on the second reflected light signal; or, when the detection signal emitted by the first sensing device 51 is not reflected by the first reflective surface 611 but is absorbed by the carrier 100, the first sensing device 51 that does not receive the reflected light signal will also determine that the corresponding first track 11 (i.e., the first stopper 30) has the carrier 100.

[0136] When the detection light source emitted by the second sensing device 52 is reflected by the second reflective surface 612, a corresponding third reflected light signal will be formed. The second sensing device 52 will receive the third reflected light signal and determine based on the reflected light signal that there is no carrier 100 at the corresponding second track 12 (i.e., the second stopper 40).

[0137] When the detection signal emitted by the second sensing device 52 is not reflected by the second reflective surface 612 but is reflected by the carrier 100 to form a corresponding fourth reflected light signal, the second sensing device 52 will receive the fourth reflected light signal and determine that the corresponding second track 12 (i.e., the second stopper 40) has the carrier 100 based on the fourth reflected light signal; or, when the detection signal emitted by the second sensing device 52 is not reflected by the second reflective surface 612 but is absorbed by the carrier 100, the second sensing device 52 that does not receive the reflected light signal will also determine that the corresponding second track 12 (i.e., the second stopper 40) has the carrier 100.

[0138] The biological sample transmission module further includes a second reflector 62 , which is disposed on the partition plate 13 and has a third reflective surface 621 corresponding to the third sensing device 53 and a fourth reflective surface 622 corresponding to the fourth sensing device 54 .

[0139] When the detection light source emitted by the third sensing device 53 is reflected by the third reflective surface 621, a corresponding fifth reflected light signal will be formed. The third sensing device 53 will receive the fifth reflected light signal and determine that there is no carrier 100 at the corresponding first track 11 based on the reflected light signal.

[0140] When the detection signal emitted by the third sensing device 53 is not reflected by the third reflective surface 621 but is reflected by the carrier 100 to form a corresponding sixth reflected light signal, the third sensing device 53 will receive the sixth reflected light signal and determine that the corresponding first track 11 has the carrier 100 based on the sixth reflected light signal; or, when the detection signal emitted by the third sensing device 53 is not reflected by the third reflective surface 621 but is absorbed by the carrier 100, the third sensing device 53 that does not receive the reflected light signal will also determine that the corresponding first track 11 has the carrier 100.

[0141] When the detection light source emitted by the fourth sensing device 54 is reflected by the fourth reflective surface 622, a corresponding seventh reflected light signal will be formed. The fourth sensing device 54 will receive the seventh reflected light signal and determine that the corresponding second track 12 does not have the carrier 100 based on the reflected light signal.

[0142] When the detection signal emitted by the fourth sensing device 54 is not reflected by the fourth reflective surface 622 but is reflected by the carrier 100 to form a corresponding eighth reflected light signal, the fourth sensing device 54 will receive the eighth reflected light signal and determine that the corresponding second track 12 has the carrier 100 based on the eighth reflected light signal; or, when the detection signal emitted by the fourth sensing device 54 is not reflected by the fourth reflective surface 622 but is absorbed by the carrier 100, the fourth sensing device 54 that does not receive the reflected light signal will also determine that the corresponding second track 12 has the carrier 100.

[0143] In another embodiment, the first sensing device 51, the second sensing device 52, the third sensing device 53 and the fourth sensing device 54 are all light sensors, and the first sensing device 51, the second sensing device 52, the third sensing device 53 and the fourth sensing device 54 respectively only have the function of emitting a detection light source, but do not have the function of receiving a detection light source.

[0144] Furthermore, the biological sample transmission module includes a first light receiver, which is disposed on the partition plate 13 and has a first receiving surface that cooperates with the first sensing device 51 and a second receiving surface that cooperates with the second sensing device 52 .

[0145] When the first receiving surface receives the first detection light emitted by the first sensing device 51 , it indicates that there is no carrier 100 at the first track 11 (ie, the first stopper 30 ) corresponding to the first sensing device 51 .

[0146] When the first receiving surface does not receive the first detection light emitted by the first sensing device 51 , it indicates that the carrier 100 is present at the first track 11 (ie, the first stopper 30 ) corresponding to the first sensing device 51 .

[0147] When the second receiving surface receives the second detection light emitted by the second sensing device 52 , it indicates that there is no carrier 100 at the second track 12 (ie, the second stopper 40 ) corresponding to the second sensing device 52 .

[0148] When the second receiving surface does not receive the second detection light emitted by the second sensing device 52 , it indicates that the carrier 100 is present at the second track 12 (ie, the second stopper 40 ) corresponding to the second sensing device 52 .

[0149] Furthermore, the biological sample transmission module also includes a second light receiver, which is disposed on the partition plate 13 and has a third receiving surface that cooperates with the third sensing device 53 and a fourth receiving surface that cooperates with the fourth sensing device 54 .

[0150] When the third receiving surface receives the third detection light emitted by the third sensing device 53 , it indicates that there is no carrier 100 at the first track 11 corresponding to the third sensing device 53 .

[0151] When the third receiving surface does not receive the third detection light emitted by the third sensing device 53 , it indicates that the carrier 100 is located at the first track 11 corresponding to the third sensing device 53 .

[0152] When the fourth receiving surface receives the fourth detection light emitted by the fourth sensing device 54 , it indicates that the second track 12 corresponding to the fourth sensing device 54 does not have the carrier 100 .

[0153] When the fourth receiving surface does not receive the fourth detection light emitted by the fourth sensing device 54 , it indicates that the carrier 100 is located at the second track 12 corresponding to the second sensing device 52 .

[0154] See also Figure 2As shown, in one embodiment, the first track 11 or the second track 12 is connected to a first functional module 200 , and the shifting lever 20 is located upstream of the first functional module 200 .

[0155] Furthermore, the biological sample transmission module further includes a first transfer disk 70, the lever 20 is located upstream of the first transfer disk 70, and the first transfer disk 70 simultaneously separates the first track 11 and the second track 12. The first transfer disk 70 is structured to form a first transfer slot 71. The first transfer slot 71 can accommodate a carrier 100. The first transfer disk 70 rotates to make the carrier 100 accommodated in the first transfer slot 71 move synchronously.

[0156] Furthermore, the first functional module 200 has a first inner rail 210. The first transfer plate 70 rotates so that the carrier 100 entering the first transfer slot 71 from the first rail 11 or the second rail 12 can be transferred to the first inner rail 210, or the first transfer plate 70 rotates so that the carrier 100 entering the first transfer slot 71 from the first inner rail 210 can be transferred back to the first rail 11 or the second rail 12.

[0157] The first transfer tray 70 is provided to transfer the carrier 100 between the first track 11 , the second track 12 or the first inner track 210 , so that the first transfer tray 70 can take care of the first track 11 , the second track 12 and the first inner track 210 at the same time.

[0158] Furthermore, the first transfer disc 70 rotates so that the first transfer slot 71 has a first material feed position, a second material feed position, a third material feed position, a first material discharge position, a second material discharge position and a third material discharge position.

[0159] When the first transfer groove 71 is at the first feeding position, the carrier 100 located on the first track 11 upstream of the first transfer disk 70 can enter the first transfer groove 71. At this time, the first transfer disk 70 can rotate to transfer the carrier 100 in the first transfer groove 71 to the first discharging position so that the carrier 100 enters the first track 11 downstream of the first transfer disk 70, or transfer to the second discharging position so that the carrier 100 enters the second track 12 downstream of the first transfer disk 70, or transfer to the third discharging position so that the carrier 100 enters the first inner rail 210.

[0160] When the first transfer groove 71 is at the second feeding position, the carrier 100 located upstream of the first transfer disk 70 on the second track 12 can enter the first transfer groove 71. At this time, the first transfer disk 70 can rotate to transfer the carrier 100 in the first transfer groove 71 to the first discharging position so that the carrier 100 enters the first track 11 downstream of the first transfer disk 70, or transfer it to the second discharging position so that the carrier 100 enters the second track 12 downstream of the first transfer disk 70, or transfer it to the third discharging position so that the carrier 100 enters the first inner rail 210.

[0161] When the first transfer groove 71 is at the third feeding position, the carrier 100 on the first inner rail 210 can enter the first transfer groove 71. At this time, the first transfer disc 70 can rotate to transfer the carrier 100 in the first transfer groove 71 to the first discharging position so that the carrier 100 enters the first track 11 downstream of the first transfer disc 70, or transfer it to the second discharging position so that the carrier 100 enters the second track 12 downstream of the first transfer disc 70.

[0163] The second transfer plate 80 is connected to the second functional module 300 , and the lever 20 is located upstream of the second functional module 300 and the second transfer plate 80 .

[0164] The second transfer plate (80) can transfer the carrier (100) between one of the first track (11) or the second track (12) and the second functional module (300), but cannot transfer the carrier (100) between the other of the first track (11) or the second track (12) and the second functional module (300).

[0165] Furthermore, the second functional module 300 has a second inner rail. The second transfer plate 80 can transfer the carrier 100 to the second inner rail.

[0166] In one embodiment, the first track 11 is connected to the second functional module 300 via the second transfer disc 80. The second transfer disc 80 rotates so that the carrier 100 entering the second transfer slot 81 from the first track 11 can be transferred to the second inner track 310, or the second transfer disc 80 rotates so that the carrier 100 entering the second transfer slot 81 from the second inner track 310 can be transferred back to the first track 11.

[0167] The lever 20 is located upstream of the second functional module 300. When the vehicle 100 on the first track 11 needs to enter the second functional module 300, the lever 20 is in the first working position, and the vehicle 100 will move along the first track 11 and enter the second transfer slot 81. When the vehicle 100 on the first track 11 does not need to enter the second functional module 300, the lever 20 will switch to the second working position, and the vehicle 100 will change lanes to the second track 12 along the lane change intersection 131 corresponding to the lever 20.

[0168] Furthermore, the second transfer disc 80 divides the first track 11 into a first track section 111 and a second track section 112. The second transfer disc 80 rotates so that the second transfer slot 81 has a fourth feeding position, a fifth feeding position, a fourth discharging position and a fifth discharging position.

[0169] When the second transfer groove 81 is at the fourth feeding position, the outlet of the first track section 111 is connected to the second transfer groove 81 so that the carrier 100 on the first track section 111 can enter the second transfer groove 81 .

[0170] When the second transfer plate 80 rotates to place the second transfer slot 81 at the fourth discharge position, the second transfer slot 81 is connected to the entrance of the second track section 112 so that the carrier 100 in the second transfer slot 81 can enter the second track section 112 .

[0171] When the second transfer plate 80 rotates to place the second transfer slot 81 at the fifth discharge position, the second transfer slot 81 is connected to the entrance of the second functional module 300 so that the carrier 100 in the second transfer slot 81 can enter the second inner rail 310 .

[0172] When the second transfer groove 81 is at the fifth feeding position, the outlet of the second inner rail 310 is in communication with the second transfer groove 81 so that the carrier 100 of the second functional module 300 can enter the second transfer groove 81 .

[0173] In another embodiment, the second track 12 is connected to the second functional module 300 via the second transfer disk 80. The second transfer disk 80 rotates so that the carrier 100 entering the second transfer slot 81 from the second track 12 can be transferred to the second inner track 310, or the second transfer disk 80 rotates so that the carrier 100 entering the second transfer slot 81 from the second inner track 310 can be transferred back to the second track 12.

[0174] The lever 20 is located upstream of the second functional module 300. When the vehicle 100 on the second track 12 needs to enter the second functional module 300, the lever 20 is in the first working position, and the vehicle 100 will move along the second track 12 and enter the second transfer slot 81. When the vehicle 100 on the second track 12 does not need to enter the second functional module 300, the lever 20 will switch to the third working position, and the vehicle 100 will change lanes to the first track 11 along the lane change intersection 131 corresponding to the lever 20.

[0175] Furthermore, the second transfer disc 80 divides the second track 12 into a third track section 121 and a fourth track section 122. The second transfer disc 80 rotates so that the second transfer slot 81 has a sixth feed position, a seventh feed position, a sixth discharge position and a seventh discharge position.

[0176] When the second transfer groove 81 is at the sixth feeding position, the outlet of the third track section 121 is connected to the second transfer groove 81 so that the carrier 100 on the third track section 121 can enter the second transfer groove 81 .

[0177] When the second transfer plate 80 rotates to place the second transfer slot 81 at the sixth discharge position, the second transfer slot 81 is connected to the entrance of the fourth track 122 so that the carrier 100 in the second transfer slot 81 can enter the fourth track 122 .

[0178] When the second transfer plate 80 rotates to place the second transfer slot 81 at the seventh discharge position, the second transfer slot 81 is connected to the entrance of the second functional module 300 so that the carrier 100 in the second transfer slot 81 can enter the second inner rail 310 .

[0179] When the second transfer groove 81 is at the seventh feeding position, the outlet of the second inner rail 310 is connected to the second transfer groove 81 so that the carrier 100 of the second functional module 300 can enter the second transfer groove 81 .

[0180] Preferably, the second functional module 300 is connected to the first track 11 through the second transfer disk 80 .

[0181] Furthermore, in one embodiment, a plurality of the levers 20 are disposed between the first track 11 and the second track 12 , and the first track 11 or the second track 12 corresponding to any two adjacent levers 20 is connected to a third functional module 400 .

[0182] Furthermore, the third functional module 400 located between any two adjacent levers 20 may be a functional module with the same function or a functional module with different functions. For ease of understanding and description, the plurality of levers 20 may be named in order as a first lever, a second lever, and a third lever. A first third functional module 400 is provided between the first lever and the second lever, and a second third functional module 400 is provided between the second lever and the third lever. The first third functional module 400 and the second third functional module 400 may perform the same operation processing on the sample or different operation processing on the sample.

[0183] When the third functional module 400 is connected to the first track 11, by controlling the lever 20 located upstream of the third functional module 400 to be in the second working position, and the other lever 20 located downstream of the third functional module 400 to be in the third working position, the carrier 100 on the first track 11 can change lanes to the second track 12 upstream of the third functional module 400, and move along the second track 12 to the downstream of the third functional module 400 and then change back to the first track 11.

[0184] When the third functional module 400 is connected to the second track 12, by controlling the lever 20 located upstream of the third functional module 400 to be in the third working position, and the other lever 20 located downstream of the third functional module 400 to be in the second working position, the carrier 100 on the second track 12 can change lanes to the first track 11 upstream of the third functional module 400, move along the first track 11 to the downstream of the third functional module 400, and then change back to the second track 12.

[0185] Further, the second ends 22 of the plurality of levers are respectively located upstream of the corresponding first ends 21. That is to say, when the plurality of levers 20 are arranged between the first track 11 and the second track 12, the second end 22 of each lever 20 is close to the first end 21 of another lever 20 located upstream of the lever 20. Thus, the vehicle can pass between the first track 11 and the second track 12 by controlling the working positions between the adjacent levers 20.

[0186] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0187] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0188] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
