[0081] Reference Figure 1 and Figure 2The blood collection tube processing mechanism includes a blood collection tube receiving part 3100, a conveying part 3000, a loading device 2000, a blood collection tube rolling scanning mechanism 4000 and a sorting mechanism 6000. The blood collection tube in the blood collection tube receiving part 3100 is moved to the conveying part 3000 by the loading device 2000, and the blood collection tube is transported to the blood collection tube rolling scanning mechanism 4000 by the conveying part 3000, and then the scanned blood collection tube is sorted by the sorting mechanism 6000 according to the scanned information.

[0082] Reference Figure 3 , shows a side view of a feeding device that can be used for blood collection tubes in the first embodiment, the feeding device includes a material guiding structure 1000 and a feeding device 2000, the material guiding structure 1000 includes a first guide plate 1100 and a second guide plate 1200, the first guide plate 1100 has a connecting end 1110, the first guide plate 1100 is connected to the second guide plate 1200 via the connecting end 1110, the feeding device 2000 includes a feeding collection structure 2100 and a driving structure 2200, the feeding collection structure 2100 is used to collect blood collection tubes, the driving structure 2200 can drive the feeding collection structure 2100 to move, and the feeding device 2000 in the first embodiment has a plurality of feeding collection structures 210 0, the gap between the connecting end 1110 and the loading and collecting structure 2100 is smaller than the maximum length of the blood sampling tube. When the blood sampling tube moves to the connecting end 1110 of the first guide plate 1100, only a part of the blood sampling tube can pass through the gap and fall into the second guide plate 1200, thereby being located between the second guide plate 1200 and the loading device. The loading and collecting structure 2100 moved to the second guide plate 1200 passes through the second guide plate 1200, thereby collecting part of the blood sampling tube located between the second guide plate 1200 and the loading device onto the loading and collecting device 2100. The blood sampling tube maintains its posture on the loading and collecting device 2100 and is transported to the subsequent processing station, thereby achieving a certain arrangement and sorting effect.

[0083] To clearly observe the gap between the connecting end of the first guide plate and the loading and collecting structure, refer to Figure 4 , Figure 4 for Figure 3 A top view of a feeding device for blood collection tubes, when the blood collection tube moves along the first guide plate 1100 of the guide structure 1000 to the connection end 1110, because the gap between the connection end 1110 and the loading and collecting structure 2100 is smaller than the maximum length of the blood collection tube, only a part of the blood collection tube can pass through the gap to reach the second guide plate 1200, and then be collected by the loading and collecting structure 2100, and then continue to move and transport to the subsequent processing station under the driving action of the driving structure 2200. Figure 5Taking the middle direction as an example, when the randomly arranged blood collection tubes move along the first guide plate 1100 of the material guide structure 1000 to the connecting end 1110, the blood collection tubes with the correct posture can directly fall from the gap into the second guide plate 1200 and be located between the second guide plate 1200 and the loading device 2000. The blood collection tubes with the correct posture here refer to the blood collection tubes whose length extending in the left-right direction is less than the gap between the connecting end 1110 and the loading and collecting structure 2100. Such blood collection tubes are collected by the loading and collecting device 2100 passing through the second guide plate 1200, so that the blood collection tubes are maintained on the loading and collecting device 2100 in a posture extending in the front-to-back direction, and are transported to the subsequent workstations as the loading and collecting device 2100 circulates, thereby realizing the sorting of the blood collection tubes. Blood collection tubes with incorrect postures fail to directly pass through the above-mentioned gap and fall into the second guide plate 1200. Blood collection tubes with incorrect postures here refer to blood collection tubes whose length extending in the left-right direction is greater than the gap between the connecting end 1110 and the loading and collecting structure 2100, such as blood collection tubes spanning over the gap in the left-right direction, etc., and therefore fail to directly fall into the second guide plate 1200. However, due to the collision of blood collection tubes subsequently transported by the material guide structure 1000 and / or the push of the loading and collecting device 2100 that continuously flows through the gap, these blood collection tubes have a chance to adjust their postures so that they can pass through the gap and fall into the second guide plate 1200, and then can be collected by the loading and collecting device 2100 and maintained in the direction of extending forward and backward for transportation to the subsequent workstation, thereby realizing the sorting and arrangement of blood collection tubes with correct postures.

[0084] See also Figure 5 , shows a partial enlarged view of a feeding device that can be used for blood collection tubes in the second embodiment, the second guide plate 1200 has a first avoidance groove 1210, and when the loading and collecting structure 2100 moves to the second guide plate 1200, the loading and collecting structure 2100 can pass through the first avoidance groove 1210. In some embodiments, the first avoidance groove 1210 has a bent free end 1220, and the free end 1220 is bent in the direction opposite to the second guide plate 1200 of the blood collection tube. When the blood collection tube moves from the first guide plate 1100 to the second guide plate 1200, the free end 1220 is bent in the direction opposite to the direction of the blood collection tube on the second guide plate 1200, so it will not hang on the blood collection tube, thereby preventing the blood collection tube from being scratched by the end face of the free end 1220, and ensuring the integrity of the blood collection tube structure.

[0085] See also Figure 7 , shows a stereoscopic view of a loading device 2000 in a feeding device that can be used for blood collection tubes in a third embodiment, the loading device 2000 includes a loading and collecting structure 2100 and a driving structure 2200, the loading and collecting structure 2100 is used to collect blood collection tubes, the driving structure 2200 can drive the loading and collecting structure 2100 to move, and the loading device 2000 in the third embodiment has a plurality of loading and collecting structures 2100.

Figure 8 for Figure 7 The front view of the upper material collection structure 2100, wherein the collection block 2120 in the upper material collection structure 2100 has a bending portion 2121 and an end portion 2122, the bending portion 2121 has a first end 2123 and a second end 2124, the collection block 2120 is connected to the connecting arm 2110 through the first end 2123, the second end 2124 is connected to the end portion 2122, and the end portion 2122 has a free end 2125. Figure 8 Taking the direction shown as an example, the bending portion 2121 extends from the first end 2123 to the second top end 2124 and has an upward extension tendency, and the end 2122 extends from the second end 2124 to the free end 2125 and has a downward extension tendency. The extension trend direction of the bending portion 2121 is opposite to the extension trend direction of the end 2122, so that the part extending from the bending portion 2121 to the end 2122 is an arc, so that the highest point of the collecting block 2120 has a convex arc surface, and when the blood collection tube enters the loading and collecting structure 2100, the integrity of the blood collection tube structure can be maintained.

[0086] In the second embodiment, the driving structure 2200 includes a synchronous belt 2210 and a synchronous pulley 2220 . The material loading and collecting structure 2100 is disposed on the synchronous belt 2210 . The synchronous pulley 2220 drives the synchronous belt 2210 to move, thereby driving the movement of the material loading and collecting structure 2100 .

[0087] See also Fig. 9 , Fig. 9 It is a front view of the loading and collecting structure 2100 in the feeding device that can be used for the blood collection tube in the fourth embodiment. The end 2122 in the loading and collecting structure 2100 is located at the extension part of the bending part 2121 along the second end 2124. The end 2122 is arranged in an arc surface, so that the highest point of the collection block 2120 has a convex arc surface, which is beneficial to the blood collection tube to maintain the structural integrity.

[0088] See also Fig.10 , Fig.10 FIG. 2 is a perspective view of a feeding device 2000 in a feeding device for blood collection tubes in a fifth embodiment. Fig.12 for Fig.10The side view of the loading device 2000, the loading device 2000 also includes a blood collection tube detachment structure 2300. When the loading and collecting structure 2100 is driven by the first driving device 2200 to move to the blood collection tube detachment structure 2300, the blood collection tubes collected by the loading and collecting structure 2100 can be detached and transferred to the blood collection tube detachment structure 2300. The blood collection tube detachment structure 2300 can be used to connect with a subsequent workstation, so that the blood collection tubes can be sent to a subsequent processing station through the blood collection tube detachment structure 2300. Fig.12 FIG. 2 is a perspective view of the feeding device 2000 from another perspective. The blood collection tube separation structure 2300 has a separation plate 2310 and a second avoidance groove 2320. In order to clearly see the positional relationship between the feeding and collecting structure 2100 and the blood collection tube separation structure 2300, see FIG. Fig.13 , Fig.13 FIG. 2 is a partial top view of the loading device. When the loading and collecting structure 2100 is driven by the first driving device 2200 to move to the blood collection tube detaching structure 2300, the connecting arm 2110 and the collecting block 2120 of the loading and collecting structure 2100 can pass through the second avoidance groove 2320, while the blood collection tubes collected by the loading and collecting structure 2100 are blocked by the detachment plate 2310 and cannot pass through the second avoidance groove 2320, so that the blood collection tubes are detached from the loading and collecting structure 2100. Fig.12 The loading process of the loading device is as follows: the blood collection tubes are collected and placed on the loading and collecting structure 2100. The blood collection tubes are not easy to fall off under the obstruction of the collecting block, and because the highest point of the collecting block has a convex curved surface, the blood collection tubes are not easy to be damaged and can maintain their structural integrity. Then, the blood collection tubes are driven by the first driving device 2110 and move with the loading and collecting structure 2100. When moving to the blood collection tube detachment structure 2300, the loading and collecting structure 2100 can pass through the second avoidance groove 2320 of the blood collection tube detachment structure 2300, and the blood collection tubes are blocked by the detachment plate 2310, thereby detaching from the loading and collecting structure 2100.

[0089] In order to facilitate the smooth detachment of the blood collection tube from the loading and collecting structure and its transfer to the blood collection tube detachment structure without falling off again, the contour line of the avoidance groove in the blood collection tube detachment structure should be slightly wider than the contour line of the loading and collecting structure. In some embodiments, the width of the avoidance groove 2310 is wider than the width of the collection block 2120, and the width of the avoidance groove 2310 is narrower than the maximum length of the blood collection tube, ensuring that the loading and collecting structure can successfully pass through the avoidance groove while the blood collection tubes collected by the loading and collecting structure are blocked by the detachment plate and do not fall off again.

[0090] See also Fig.14 , Fig.14This is a top view of the loading and collecting structure 2100 in the fifth embodiment. The collecting blocks 2120 are arranged on the connecting arm 2110 at a certain interval in a comb-like arrangement. The collecting blocks 2120 arranged in a comb-like arrangement can comb the blood collection tubes, which is conducive to the neat arrangement of the blood collection tubes.

[0091] Reference Fig.15 , Fig.15 FIG. 2 shows a schematic diagram of the structure of an embodiment of a blood collection tube scanning device of the present invention. Fig.15 As shown, the blood collection tube scanning device of this embodiment includes a blood collection tube rolling scanning mechanism 4000, which loads the blood collection tube to be scanned to the scanning area through the loading device 2000 and the conveying component 3000. The blood collection tube rolling scanning mechanism 4000 is mainly used to drive the blood collection tube placed in the scanning area to roll, and scan the scanning code on the wall of the blood collection tube to obtain scanning information.

[0092] The blood collection tube receiving part 3100 is used to collect and place the blood collection tubes to be scanned, and the material guide structure 1000 is located at the bottom of the blood collection tube receiving part 3100. The loading device 2000 is used to load the blood collection tubes in the blood collection tube receiving part 3100; the conveying part 3000 is used to comb and convey the loading parts (i.e., the blood collection tubes to be scanned) in a single row. Fig.15 As shown, the loading device 2000 is partially located inside the blood collection tube receiving part 3100, and is arranged below the loading device 2000. The conveying part 3000 is received and arranged above the loading device 2000. The blood collection tubes to be scanned in the blood collection tube receiving part 3100 are transferred upward through the loading device 2000 and then loaded onto the conveying part 3000.

[0093] See also Fig.16 and Fig.17 , Fig.17 The schematic diagram of the structure of the conveying component 3000 in this embodiment is shown; the conveying component 3000 includes a conveyor belt 3310 and a first baffle 3320 and a second baffle 3330 respectively arranged on both sides of the conveyor belt 3310. The width of the conveyor belt 3310 is greater than the maximum diameter of the blood collection tube and less than twice the maximum diameter of the blood collection tube; in order to facilitate the single-line conveying of the blood collection tube on the conveyor belt 3310, the width of the conveyor belt 3310 is greater than the maximum diameter of the blood collection tube and less than 3 / 2 of the maximum diameter of the blood collection tube. The conveying component 33 specifically drives the conveyor belt 3310 to move through a driving device to transport materials.

[0094] The first baffle 3320 and the second baffle 3330 are both arranged along the conveying direction of the conveyor belt 3310; the first baffle 3320 is provided with a first discharge port 3340, and the second baffle 3330 is provided with a second discharge port 3350. The first discharge port 3340 and the second discharge port 3350 are arranged opposite to each other, and the distance between the bottom of the first discharge port 3340 and the bottom of the second discharge port 3350 and the conveyor belt 3310 is less than the maximum diameter of the blood collection tube, and is used for the recovery and discharge of non-single-row blood collection tubes. Among them, the non-single-row blood collection tube is specifically the blood collection tube stacked on the blood collection tube attached to the conveyor belt 331. For example, if blood collection tube B is stacked on blood collection tube A attached to the conveyor belt 3310, that is, blood collection tube B is stacked on the lower layer blood collection tube A, and blood collection tube B makes the blood collection tubes arranged in a non-single layer along the conveying direction perpendicular to the conveyor belt 331, then blood collection tube B stacked on blood collection tube A is a non-single-row blood collection tube. In this embodiment, the first baffle 3320 is arranged on the same side as the loading device 2000 ; in addition, the first baffle 3320 and the second baffle 3330 are both arranged perpendicular to the conveying surface of the conveyor belt 3310 .

[0095] Generally speaking, the minimum width of the first discharge port 3340 and the second discharge port 3350 along the conveying direction of the conveyor belt 3310 is greater than the length of the blood collection tube. In order to facilitate the discharge of non-single-row blood collection tubes, the bottom of the first discharge port 3340 and the bottom of the second discharge port 3350 can be set to be less than or equal to half of the maximum diameter of the blood collection tube. Through the above structural setting, the non-single-row blood collection tube cannot obtain the support force of the baffle at the discharge port, so that the force on the lower layer of blood collection tubes is unbalanced, which is more conducive to the discharge of non-single-row blood collection tubes.

[0096] In this embodiment, the first discharge port 3340 and the second discharge port 3350 are both recessed discharge ports that are recessed toward the conveyor belt 3310 and open at the upper end. By adopting the recessed discharge port approach, the structure is easier to implement and can be applied to blood collection tubes of different diameters, thereby expanding the range of applicable blood collection tubes.

[0097] In addition, the front end of the first discharge port 3340 along the conveying direction of the conveyor belt 3310 has a first side wall 3360, and the front end of the second discharge port 3350 along the conveying direction of the conveyor belt 3310 has a second side wall 3370; and along the conveying direction of the conveyor belt 3310, the first side wall 3360 is located in front of the second side wall 3370; the distance (i.e., the horizontal distance) between the first side wall 3360 and the second side wall 3370 is greater than the maximum diameter of the blood collection tube and less than half of the length of the blood collection tube. By staggering the first side wall 3360 on the first discharge port 3340 and the second side wall 3370 on the second discharge port 3350 in the conveying direction of the conveyor belt 3310, the discharge and recovery of non-single-row blood collection tubes can be further facilitated. Specifically, in the case where the front end of the non-single-row blood collection tube on the lower layer is deflected and tilted toward the second side wall 3370, when the non-single-row blood collection tube is transmitted to abut against the second side wall 3370, the second side wall 3370 prevents the single-row blood collection tube from moving forward, and the conveyor belt 3310 drives the lower layer of blood collection tubes to continue moving forward, thereby prompting the other end of the upper layer of the non-single-row blood collection tube to rotate, and even rotate to abut against the first side wall 3360. The first side wall 3360 and the second side wall 3370 simultaneously prevent the non-single-row blood collection tube from moving forward, causing the non-single-row blood collection tube to be unbalanced in force, and fall through the discharge port into the recovery component 3400, thereby achieving single-row combing of the blood collection tubes.

[0098] In order to further improve the single-row combing and conveying effect, a second blocking portion 3380 can also be provided on the conveying component 3000. The second blocking portion 3380 is provided between the first baffle plate 3320 and the second baffle plate 3330, and is located in front of the first discharge port 3340 and the second discharge port 3350 along the feeding direction of the conveyor belt 3310; the distance between the second blocking portion 338 and the conveyor belt 3310 (i.e., the height with the conveying surface as the reference plane) is greater than the maximum diameter of the blood collection tube and less than twice the maximum diameter of the blood collection tube. The second blocking portion 3380 is generally arranged near the first discharge port 3340 and the second discharge port 3350. For the situation where the non-single-row blood collection tubes fail to discharge naturally after passing through the first discharge port 334 and the second discharge port 3350, and fail to discharge through the cooperation of the first side wall 3360 and the second side wall 337, the second blocking portion 3380 is arranged, and the non-single-row blood collection tubes continue to move forward to the location where the second blocking portion 3380 is arranged, and their forward movement may be blocked by the second blocking portion 3380, and even the non-single-row blood collection tubes may be subjected to the reverse thrust of the second blocking portion 3380 during the forward movement, and fall into the recovery component 3400 through the nearby discharge port, thereby further realizing the single-row combing of the blood collection tubes and realizing the single-row transportation of the blood collection tubes.

[0099] The recovery component 3400 is disposed below the conveying component 3000, specifically below the first discharge port 3340 and the second discharge port 3350, and is obliquely connected to the blood collection tube receiving component 3100, so that the non-single-row blood collection tubes dropped from the first discharge port 3340 and the second discharge port 3350 fall back into the blood collection tube receiving component 3100 under the action of gravity. In this embodiment, the recovery component 3400 and the blood collection tube receiving component 3100 are arranged side by side, and are arranged on the same side of the loading device 2000 along the conveying direction of the conveyor belt 3310.

[0100] In this embodiment, the recovery component 3400 is tilted to utilize gravity to recover the non-single-row blood collection tubes. In addition, other structures can also be used to achieve recovery, for example, a driving device drives a pushing component (such as a pushing plate) to push the non-single-row blood collection tubes that fall into the recovery component 3400 into the blood collection tube receiving component 3100.

[0101] In the above single-row conveying mechanism for blood collection tubes, the first and second baffles 3320 and 3330 respectively disposed on the two sides of the conveyor belt 331 are provided with a first discharge port 3340 and a second discharge port 3350, and the first discharge port 3340 and the second discharge port 3350 are disposed opposite to each other. Through the above arrangement of the first discharge port 3340 and the second discharge port 3350, when the non-single-row blood collection tubes loaded on the conveyor belt 3310 are transported to the discharge port position, some non-single-row blood collection tubes are prone to force imbalance due to the loss of the support of the baffles on both sides, and then fall from the first discharge port 334 or the second discharge port 335 to the recovery component 3400, and then are sent back to the blood collection tube receiving component 3100 through the recovery component 3400. In the above manner, both sides of the conveyor belt 3310 can discharge and recover, so that the single-row sorting and transportation of blood collection tubes can be realized, and the occurrence of tube jamming can be reduced. In other embodiments, other blood collection tube single-file transport mechanisms that can realize single-file transport of blood collection tubes may also be used.

[0102] See also Fig.13 , Fig.15 and Fig.16 , Fig.16The schematic diagram of the structure of the blood collection tube pushing mechanism in this embodiment is shown. The blood collection tube pushing mechanism 3500 is arranged on one side of the discharge end of the upper conveyor belt 3310 of the blood collection tube single-row conveying mechanism. The blood collection tube pushing mechanism 3500 includes a fourth driving device 3510, a mounting portion 3520 provided with a slide rail, and a sliding push portion 3530 connected to the slide rail on the mounting portion 3520; the slide rail is specifically arranged perpendicular to the conveying direction of the discharge end of the blood collection tube single-row conveying mechanism. The sliding push portion 3530 is arranged above the conveyor belt 3310 at the discharge end of the blood collection tube single-row conveying mechanism, and a limiting card slot 3540 is provided on the sliding push portion 3530, and the opening direction of the limiting card slot 3540 is opposite to the conveying direction of the upper discharge end of the blood collection tube single-row conveying mechanism, and is used to receive the blood collection tube conveyed by the blood collection tube single-row conveying mechanism. The fourth driving device 3510 is used to drive the sliding pusher 3530 to reciprocate along the slide rail, so as to push the blood collection tube received by the limiting card slot 3540 to the scanning area. The width of the limiting card slot 3540 is greater than the maximum diameter of the blood collection tube, and its depth along the conveying direction of the blood collection tube single-line conveying mechanism is generally greater than or equal to half the length of the blood collection tube, so as to facilitate the stable pushing of the blood collection tube. Furthermore, the depth of the limiting card slot 3540 can be set to be greater than or equal to the length of the blood collection tube.

[0103] In order to prevent the blood collection tube from deviating from the upper side of the limiting slot 3540 and falling out of the limiting slot 3540 during the pushing process, a third blocking component 3550 may be provided above the limiting slot 3540, and the height of the third blocking component 3550 from the conveying surface of the single-row conveying mechanism for the blood collection tube is greater than the maximum diameter of the blood collection tube.

[0104] In addition, if Fig.13 and Fig.16 As shown, in this embodiment, the blood vessel scanning device further includes an auxiliary support frame 3600, which is fixedly connected to the mounting portion 3520 of the blood collection tube pushing mechanism 3500 and the conveying component 3000, and is used to auxiliary support and fix the blood collection tube pushing mechanism 3500 and the conveying component 3000. In other embodiments, the auxiliary support frame 3600 may be eliminated, and the stability of the overall device may be ensured by adjusting the structure of the blood collection tube pushing mechanism 3500.

In this embodiment, the first roller 4210 and the second roller 4220 are arranged perpendicularly relative to the pushing direction of the blood collection tube pushing mechanism 3500.

[0108] The driving assembly 4300 is used to drive the first roller 4210 and the second roller 4220 to rotate in the same direction, and to drive the first roller 4210 and the second roller 4220 to relatively open and close motion, so that the first roller 4210 and the second roller 4220 have a closed state and an open state during the relative opening and closing motion; and in the closed state, the gap between the first roller 4210 and the second roller 4220 is smaller than the maximum diameter of the blood collection tube, so that the blood collection tube to be scanned can be placed between the first roller and the second roller; and in the open state, the gap between the first roller 4210 and the second roller 4220 is larger than the maximum diameter of the blood collection tube, so that the blood collection tube can be dropped after the scanning is completed. Specifically, the driving assembly 4300 drives the first roller 4210 and the second roller 4220 to rotate in the same direction, thereby driving the blood collection tube located between the first roller 4210 and the second roller 4220 to roll, and then scan. The driving assembly 4300 drives the first roller 4210 and the second roller 4220 to move in relative opening and closing, so as to realize the dropping of the blood collection tube after the scanning is completed. In this embodiment, the driving assembly 4300 includes an opening and closing driving assembly 4310 and a rotating driving assembly 4320; the opening and closing driving assembly 4310 is used to drive the first roller 4210 and the second roller 4220 to move in relative opening and closing; the rotating driving assembly 4320 is used to drive the first roller 4210 and the second roller 4220 to rotate in the same direction.

[0109] The opening and closing driving assembly 4310 includes a cam transmission mechanism 4330 and a swing connection assembly 4340. The cam transmission mechanism 433 includes a first rotating shaft 4332, a cam 4333 and a second driving device 4331; the first rotating shaft 4332 is rotatably arranged on the main mounting plate 411 of the mounting bracket 4100, the cam 4333 is fixedly arranged on the first rotating shaft 4332, and the second driving device 4331 is used to drive the first rotating shaft 4332 to rotate and then drive the cam 4333 to rotate.

[0110] The swing connection assembly 4340 includes a swing member 4345, a first support connection member 4343, and a second support connection member 4342. One end of the swing member 4345 abuts against the circumference of the cam 4333, and the other end is fixedly connected to the first support connection member 4343 and the second support connection member 4342; one end of the first support connection member 4343 and the second support connection member 4342 are rotatably connected to the two ends of the first roller shaft 4210, respectively, and the other end is rotatably disposed on the main mounting plate 4110 of the mounting bracket 4100 through the second rotating shaft 4344.

The receiving and feeding portion 4130 is fixed on the mounting bracket 4100. The receiving and feeding portion 4130 has a receiving surface 4131 and a blocking surface 4132. The receiving surface 4131 of the receiving and feeding portion 4130 is flush with the conveying surface of the blood collection tube single-row conveying mechanism, so as to serve as a connection between the conveying surface and the scanning area, so as to facilitate the blood collection tube pushing mechanism 3500 to push the blood collection tube to be scanned to the scanning area. The blocking surface 4132 is used to prevent the blood collection tube from falling from the side of the second roller 4220 away from the first roller 4210. In other embodiments, the setting of the receiving and feeding portion 4130 can also be cancelled, and other structural blocking portions for preventing the blood collection tube from falling from the side are set on the side of the second roller 4220 away from the first roller 4210.

[0115] like Fig.16 and Fig.18As shown, the rotation drive assembly 4320 includes a third drive device (not shown in the figure), a drive wheel 4326, an intermediate transmission wheel 42b, a first transmission wheel 4321, a second transmission wheel 43254322, a first transmission belt 4323 and a second transmission belt 4324; the output shaft of the third drive device is connected to the drive wheel 4326; the intermediate transmission wheel 4333 is arranged at one end of the second rotating shaft 4344, the first transmission wheel 4321 is arranged at one end of the first roller 421, and the second transmission belt 4324 is arranged at one end of the second rotating shaft 4344.

[0116] Of course, the rotation driving assembly 4320 of other structures can also be used to drive the first roller 4210 and the second roller 4220 to rotate in the same direction.

[0117] The barcode scanner is disposed above the gap between the first roller 4210 and the second roller 4220 to scan the blood collection tube stuck between the first roller 4210 and the second roller 4220. It can be understood that the area between the first roller 4210 and the second roller 4220 corresponding to the bottom of the barcode scanner is the scanning area.

[0118] A material discharge component (not shown in the figure) may also be provided below the first roller 4210 and the second roller 4220 to guide the blood collection tubes that fall after the first roller 4210 and the second roller 4220 are opened and dropped after scanning to fall into the material discharge point 5100 .

[0119] When the blood sampling tube scanning device of the present embodiment is in use, the blood sampling tubes to be scanned in the blood sampling tube receiving part 3100 are loaded onto the conveying part 3000 by the loading device 2000, and are further sorted into single columns during the conveying process of the conveying part 3000. The non-singled blood sampling tubes fall into the recovery part 3400 through the unloading ports on the baffles on both sides of the conveyor belt 3310, and are then returned to the blood sampling tube receiving part 3100 by the recovery part 3400 for re-loading, thereby realizing the single column sorting and conveying of the blood sampling tubes to be scanned by the blood sampling tube single column conveying mechanism; in addition, when the blood sampling tubes to be scanned are conveyed to the discharge end of the blood sampling tube single column conveying mechanism, they enter the limiting card slot 3540 of the blood sampling tube pushing mechanism 3500, and then the sliding pushing part 3530 is driven by the fourth driving device 3510 to move along the slide rail on the mounting part 3520 The blood collection tube is moved to push the blood collection tube to the scanning area between the first roller 4210 and the second roller 4220 through the receiving surface 4131 of the blood collection tube rolling scanning mechanism 400 that receives the feeding part 4130; after the blood collection tube is pushed to the scanning area, the blood collection tube pushing mechanism 3500 returns to the original position to perform the next round of pushing operation; at the same time, the first roller 4210 and the second roller 4220 are driven to rotate in the same direction by the rotating driving component 4320, thereby driving the blood collection tube to be scanned to roll, and in the process of rolling the blood collection tube, the scanning code on the wall of the blood collection tube is scanned by the scanner to obtain the scanning code information, and after the scanning is completed, the first roller 4210 and the second roller 4220 are driven to open by the opening and closing driving component 4310, so that the blood collection tube falls into the unloading component after the scanning is completed, so that the blood collection tube after the scanning is guided to the specified position by the unloading component.

[0120] As described above, the blood collection tube scanning device of this embodiment can realize active rotation scanning of the blood collection tube, and on this basis, can realize the separation of feeding and scanning actions, so that the blood collection tube pushing mechanism 3500 can immediately return to the original position after pushing the blood collection tube into place to prepare for the next round of pushing and feeding operations, and during this period, the blood collection tube is scanned and dropped through the blood collection tube rolling scanning mechanism 4000. In this way, the speed of blood collection tube scanning and sorting can be greatly improved, and the work efficiency can be improved.

[0121] For the sorting mechanism 5000, the sorting mechanism includes a collecting body, refer to Fig.19 and Fig. 20As shown, an embodiment of the collector includes a first collecting box 5700, a first buffer box 6100 and a movable plate 6300, wherein the first buffer box 6100 is located above the first collecting box 5700, and the side of the first buffer box 6100 adjacent to the first collecting box 5700 is a bottom wall, on which a notch 6130 is provided, and the side of the first collecting box 5700 adjacent to the first buffer box 6100 is provided with a top wall, three sides of the top wall are in contact with the side walls of the first collecting box 5700, and the other side is suspended, so that the first collecting box 5700 forms an opening on the top wall, and the first collecting box 5700 is connected to the first buffer box 6100 through the opening and the notch 6130, so that the first collecting box 5700 and the first buffer box 6100 are connected, so that the first collecting box 5700 and the first buffer box 6100 are connected. The blood collection tube 6600 enters the first collection box 5700, and the shaft 6400 is arranged near the notch 6130. The movable plate 6300 can rotate around the shaft 6400. The rotating plate includes a first plate 6310 and a second plate 6320. The first plate 6310 and the second plate 6320 are fixedly connected to form an L-shaped structure. The movable plate 6300 is connected to the shaft 6400 through the connection between the first plate 6310 and the second plate 6320, and rotates around the shaft 6400 through the connection. The movable plate 6300 that can rotate around the shaft 6400 has two states. When the movable plate 6300 rotates around the shaft 6400, the first plate 6310 on the movable plate 6300 closes the notch 6130, as shown in FIG. Fig.21 As shown, when the first cache box 6100 and the first collection box 5700 are not connected, the gap 6130 is in a closed state. When the movable plate 6300 rotates around the axis 6400, the first plate 6310 on the movable plate 6300 does not form a closed structure for the gap 6130, so that the first cache box 6100 and the first collection box 5700 can be connected to each other, and the second gap 6130 is in an open state.

[0122] The present embodiment also includes a frame 6500, and the first collection box 5700 can slide relative to the frame 6500, so that the first collection box 5700 can extend into the frame 6500, or detach from the frame 6500. When the first collection box 5700 changes from a state of being detached from the frame 6500 to a state of being extended into the frame 6500, the top wall of the first collection box 5700 resists the second plate 6320 on the movable plate 6300 during the movement, and the second plate 6320 is constantly close to the bottom of the first buffer box, thereby driving the second buffer box 5700 to move toward the bottom of the first buffer box. A plate 6310 moves so that the first plate 6310 is disengaged from the notch 6130, so that the first collection box 5700 is connected to the first cache box. When the first collection box 5700 moves from the frame 6500 in a direction away from the frame 6500, the top wall of the first collection box 5700 is gradually withdrawn from the frame 6500, so that the top wall no longer resists the second plate 6320, so that the second plate 6320 begins to reset, and a plate closes the notch 6130, so that the first collection box 5700 and the first cache box are not connected to each other.

[0123] This embodiment includes a collection body formed by arranging several sets of first collection boxes 5700 and first buffer boxes in parallel.
