[0023] To address the problems existing in the prior art, embodiments of this application provide an intelligent biological sample sorting system, referencing... Figure 1 As shown, the system includes a first rotating stack 200, a transfer robot 300, a barcode scanning module 400, a biosample counter 500, and a second rotating stack 600, all mounted on a base 100. The first rotating stack 200 has several first storage racks 210 for storing culture dishes 700 to be tested, with at least one rack being empty. The transfer robot 300 is positioned close to the first rotating stack 200 to transfer the culture dishes 700 to be tested from the first storage racks 210 to the barcode scanning module 400 for scanning, and then transfers the scanned culture dishes 700 to the biosample counter 500. Once the culture dishes 700 enter the biosample counter 500, the biosample counter 500 counts the number of biological samples in the culture dishes 700. The second rotating stack 600 is positioned close to the transfer robot 300 and has several second storage racks 610.

[0024] In operation, culture dishes 700 to be tested are pre-placed on a portion of the first storage rack 210. The transfer robot 300 transfers the culture dishes 700 to be tested on the first storage rack 210 to the barcode scanning module 400 for scanning, and then transfers the scanned culture dishes 700 to the biological sample counter 500 for counting. When the biological sample counter 500 calculates that the number of biological samples in the culture dishes 700 is greater than a threshold, the transfer robot 300 transfers the culture dishes 700 to the empty first storage rack 210. When the biological sample counter 500 calculates that the number of biological samples in the culture dishes 700 is less than a threshold, the transfer robot 300 transfers the culture dishes 700 to the second storage rack 610 on the second rotating stack 600.

[0025] In this embodiment, the coordinated operation of the first rotating stack 200, the transfer robot 300, the barcode scanning module 400, the biological sample counter 500, and the second rotating stack 600 not only achieves automated biological sample counting but also enables automatic classification based on the quantity of biological samples, greatly improving work efficiency. In this embodiment, the biological sample counter 500 can be a colony counter, and the biological sample can be a colony.

[0026] It should be noted that the first storage rack 210 and the second storage rack 610 have the same structure and are both used to store culture dishes 700. Therefore, only the first storage rack 210 will be described in the following embodiments.

[0027] In some embodiments, by setting a control program, when the biosample counter 500 calculates that the number of biological samples in the culture dish 700 is greater than a threshold, the transfer robot 300 can transfer the culture dish 700 to the second storage rack 610, and when the biosample counter 500 calculates that the number of biological samples in the culture dish 700 is less than the threshold, the transfer robot 300 transfers the culture dish 700 to the empty first storage rack 210.

[0028] refer to Figure 1 and Figure 2 As shown, in some embodiments, the first rotating stack 200 includes a base 220, a turntable unit 230, a lifting unit 240, and a discharging unit 250. The base 220 is fixedly mounted on the base 100 and located near one end of the base 100, and the base 220 has a hollow internal structure. The turntable unit 230 is mounted on the base 220 and can rotate on the base 220. A plurality of first storage racks 210 are spaced apart and arranged in a ring on the turntable unit 230, and their positions can be adjusted as the turntable unit 230 rotates. The lifting unit 240 is mounted on the base 220 and can be used to lift and lower the culture dishes 700 on each of the first storage racks 210. The discharging unit 250 is located on top of the lifting unit 240 and is used to transfer the culture dishes 700 to the discharging area. The transfer robot 300 is used to transfer the culture dishes 700 located in the discharging area to the barcode scanning module 400.

[0029] In this embodiment, multiple culture dishes 700 can be placed on each first storage rack 210. Since several first storage racks 210 are arranged in a ring on the turntable unit 230 at intervals, a maximum number of first storage racks 210 can be arranged on the turntable unit 230. Then, through the cooperation of the turntable unit 230, the lifting unit 240, and the discharging unit 250, the transfer robot 300 can sequentially transfer the culture dishes 700 to be tested from each first storage rack 210 to the barcode scanning module 400 for scanning, enabling automated counting of a large number of culture dishes 700 to be tested.

[0030] refer to Figure 2 and Figure 3 In some embodiments, the turntable unit 230 includes a driver 231, a transmission assembly 232, and a support plate 233. The driver 231 is located inside the base 220 and is fixedly connected to the base 220. The transmission assembly 232 has a power input end and a power output end; the power input end is connected to the driver 231, and the power output end is connected to the support plate 233 to drive the support plate 233 to rotate. A plurality of first storage trays 210 are detachably mounted on the support plate 233.

[0031] In this embodiment, the driver 231 can be a drive motor. The transmission assembly 232 includes a drive wheel 2321, several conveyor belts 2322, several synchronous pulleys 2323, and a power output wheel 2324. The driver 231 is connected to the drive wheel 2321 to form a power input end. The several synchronous pulleys 2323 are rotatably disposed inside the base 220, and the drive wheel 2321 is connected to the synchronous pulleys 2323 via several conveyor belts 2322. The power output wheel 2324 is rotatably disposed at the center of the base 220 and is connected to the synchronous pulleys 2323 via a conveyor belt 2322 to form a power output end. The support plate 233 is coaxial and fixedly connected to the power output wheel 2324. Therefore, when the driver 231 is running, the transmission assembly 232 can drive the support plate 233 to rotate.

[0032] Combination Figure 4 As shown, a through hole is further provided in the central area of ​​the top of the base 220, and through holes are also provided in the power output end and the support plate 233 corresponding to the through hole on the base 220. The lifting unit 240 includes a support member 241, a mounting frame 242, and a lifting mechanism 243. The diameter of the support member 241 is smaller than the diameter of the through hole, so that one end of the support member 241 can pass through the through holes of the base 220, the support plate 233, and the power output end, and be fixedly connected to the bottom of the base 220. When the turntable unit 230 rotates, it achieves non-interference with the support member 241. The mounting frame 242 is provided on the support member 241 and is located between the annular area enclosed by several first storage plate racks 210. The lifting mechanism 243 is provided on the mounting frame 242, and the lifting mechanism 243 has a lifting member 2437 extending to the first storage plate rack 210, which is used to lift the culture dish 700 on the first storage plate rack 210.

[0033] refer to Figure 4 and Figure 5As shown, in this embodiment, the lifting mechanism 243 includes a stepper motor 2431, a lead screw 2432, a support 2433, a lead screw nut 2434, a linear guide rail 2435, and a connecting block 2436. The linear guide rail 2435 is fixedly mounted vertically on the mounting frame 242. The connecting block 2436 is movably mounted on the linear guide rail 2435. The support 2433 is mounted on the mounting frame 242, and the lead screw 2432 is rotatably mounted on the support 2433. A stepper motor 2431 is mounted on a mounting bracket 242 and can be connected to a lead screw 2342 via a conveyor belt to drive the lead screw 2342 to rotate. A lead screw nut 2434 is rotatably mounted on the lead screw 2342, and its bottom sidewall is fixedly connected to a connecting block 2436. A lifting member 2437 is fixedly connected to the connecting block 2436. Therefore, when the stepper motor 2431 is running, it can drive the lifting member 2437 to rise steadily, thereby lifting the culture dish 700 on the first storage plate rack 210.

[0034] It is understood that in this embodiment, the carrier plate 233 is connected to the driver 231 by means of a transmission component 232, so that the driver 231 can be offset from the center of the carrier plate 233, thereby allowing the support member 241 to pass through the center of the carrier plate 233 and the power output end. The advantage of this design is that the lifting mechanism 243 can lift the culture dishes 700 on each of the first storage racks 210 in sequence without interfering with the turntable unit 230.

[0035] refer to Figures 5 to 7 As shown, in some embodiments, the support plate 233 includes a top plate 2331, a base plate 2332, and a plurality of support columns 2333. The base plate 2332 is fixedly connected to the power output end. The plurality of support columns 2333 are arranged in a ring and spaced apart on the base plate 2332, close to the edge of the base plate 2332. The top plate 2331 is disposed on the support columns 2333, maintaining a certain distance from the base plate 2332. The top plate 2331 has a plurality of notches 2334 corresponding to a plurality of first storage plate racks 210, the size of the notches 2334 being larger than the size of the lifting member 2437.

[0036] In this embodiment, when no culture dish 700 is placed in the first storage rack 210, or when the first storage rack 210 has not yet been installed on the support plate 233, the lifting mechanism 243 can first drive the lifting member 2437 to descend between the top plate 2331 and the bottom plate 2332. When it is necessary to lift the culture dish 700 to the discharge unit 250, the lifting mechanism 243 can drive the lifting member 2437 to rise. The lifting member 2437 can pass through the notch 2334 to lift the culture dishes 700 in the first storage rack 210 until all the culture dishes 700 have been transferred. It should be noted that after the culture dishes 700 in any one of the first storage racks 210 have been transferred, the turntable unit 230 rotates to transfer the culture dishes 700 in the other first storage rack 210.

[0037] In some embodiments, the first storage plate holder 210 has a storage cavity along its axial direction, and a lifting opening 211 is provided at the bottom of the storage plate holder, with each lifting opening 211 corresponding to a notch 2334. A plurality of culture dishes 700 to be tested are stacked sequentially in the storage cavity.

[0038] In operation, the lifting mechanism 243 drives the lifting component 2437 to apply force to lift the culture dish 700 through the lifting port 211 and the notch 2334, causing several culture dishes 700 to be tested to move sequentially to the discharge unit 250.

[0039] In this embodiment, the first storage rack 210 includes a base plate 212, a plurality of side plates 213 and a handle 214. The plurality of side plates 213 are spaced apart on the base plate 212 to form a storage cavity, the handle 214 is provided on the outer side wall of the base plate 212, and the base plate 212 has a lifting opening 211.

[0040] Furthermore, for different sizes of culture dishes 700, corresponding storage racks are required. For example, for culture dishes 700 with a diameter of 55mm or 90mm, the diameter of the storage cavity is set to accommodate the 55mm or 90mm culture dishes 700. In this embodiment, the top plate 2331 is provided with several limiting blocks 2335, and the bottom plate 212 of the first storage rack 210 is engaged with two adjacent limiting blocks 2335 on both sides to achieve a detachable connection between the first storage rack 210 and the top plate 2331.

[0041] In some embodiments, there are two lifting mechanisms 243, each corresponding to one of two adjacent first storage racks 210. The top of the mounting frame 242 has a mounting base 244, which has an inlet 2441 corresponding to one lifting mechanism 243 and an outlet 2442 corresponding to the other lifting mechanism 243. An outlet unit 250 is disposed on the mounting base 244 and near the outlet 2442.

[0042] In this embodiment, two lifting mechanisms 243 are provided on the first rotating stack 200 to place a classified culture dish 700 (with a biological sample quantity greater than a threshold) into an empty first storage rack 210 through the inlet 2441. Specifically, each first storage rack 210 on the first rotating stack 200 stores a culture dish 700 to be tested, while the adjacent first storage rack 210 is empty, thereby transferring the classified culture dishes 700 to the first rotating stack 200 and the second rotating stack 600 respectively. Furthermore, the discharge area is located on the side of the discharge port 2442 near the barcode scanning module.

[0043] It should be noted that the difference between the second rotating stack 600 and the first rotating stack 200 is that the second rotating stack 600 only has one lifting mechanism 243, and since the second rotating stack 600 is used to store another type of culture dish 700 for classification (the number of biological samples is less than the threshold), it only needs to set one inlet 2441 on the mounting base plate 244.

[0044] Of course, without considering cost, the second rotating stack 600 can be set to be exactly the same as the first rotating stack 200.

[0045] refer to Figure 2 and Figure 4 As shown, in some embodiments, the intelligent biological sample sorting system further includes an inlet sensor 260 and an outlet sensor 270. The inlet sensor 260 is positioned near the inlet 2441 and is used to detect the position and number of culture dishes 700 at the inlet 2441. The outlet sensor 270 is positioned near the outlet 2442 and is used to detect the position and number of culture dishes 700 at the outlet 2442.

[0046] In this embodiment, both the feed sensor 260 and the discharge sensor 270 are micro-switch sensors. By setting the feed sensor 260 and the discharge sensor 270, it is not only possible to detect whether the culture dish 700 is placed in the correct position, providing a positioning basis for the subsequent discharge unit 250 or the transfer robot 300 to grasp and transfer it. Furthermore, it can also provide real-time feedback on the number of culture dishes 700, reducing errors from manual counting and improving the accuracy of data acquisition.

[0047] In some embodiments, the first rotating stack 200 further includes a discharge scanning unit 280 and / or a storage rack scanning unit 290. The discharge scanning unit 280 is disposed on the mounting base 244 and faces the discharge area, and is used to scan the information identification code on the top cover of the culture dish 700 to further ensure the accuracy of information identification for each culture dish 700. The storage rack scanning unit 290 is disposed on the mounting bracket 242 and faces the first storage rack 210, and is used to scan the information identification code on the first storage rack 210.

[0048] In this embodiment, the information identification code can be a QR code. The top cover, side walls, and each first storage plate rack 210 of the culture dish 700 are equipped with QR codes to enhance data traceability.

[0049] refer to Figure 5 As shown, in some embodiments, the discharge unit 250 includes a moving mechanism 251, a drive motor, and a discharge gripper 252. The moving mechanism 251 includes a stepper motor and a moving platform. The moving platform is movably disposed on one side of the discharge port 2442. The stepper motor is mounted on the mounting base plate 244 and close to the discharge port 2442, and connected to the moving platform to drive its movement. The drive motor is fixedly mounted on the moving platform, and the discharge gripper 252 is connected to the drive motor.

[0050] In this embodiment, when the lifting unit 240 drives the culture dish 700 to the discharge port 2442 and the discharge sensor 270 detects a signal, the drive motor controls the discharge gripper 252 to clamp and fix the culture dish 700. Then, the moving mechanism 251 drives the drive motor, the discharge gripper 252 and the culture dish 700 to move synchronously to the discharge area. At this time, the transfer robot 300 transfers the culture dish 700 to the scanning module 400 for scanning.

[0051] refer to Figure 1 and Figure 8 As shown, in some embodiments, the scanning module 400 includes a scanning table 410, a rotary scanning unit 420, and a barcode scanner 430. The scanning table 410 is positioned close to the first rotary stack 200. The rotary scanning unit 420 is mounted on the scanning table 410 and has a turntable 421. The barcode scanner is located on one side of the rotary scanning unit 420 and faces the turntable 421.

[0052] In operation, when the transfer robot 300 transfers the culture dish 700 to be tested from the first rotating stack 200 to the turntable 421, the rotating scanning unit 420 drives the turntable 421 to rotate, and the scanner is used to scan the information identification code on the side of the culture dish 700 to be tested.

[0053] In this embodiment, a separate barcode scanning module is used to scan and record each culture dish 700, further improving the accuracy of information acquisition for each culture dish 700. The rotating scanning unit 420 only needs to have an internal drive motor to drive the turntable 421 to rotate; the specific internal structure is not limited.

[0054] In addition, a support platform can be installed at the bottom of the scanning module 400 so that the height of the scanning module 400 can be adapted to the transfer of the transfer robot 300.

[0055] In some embodiments, the transfer robot 300 includes a first robotic arm 310 and a second robotic arm 320. The first robotic arm 310 is located near the first rotating stack 200 and the barcode scanning module 400. The second robotic arm 320 is located near the second rotating stack 600 and the barcode scanning module 400.

[0056] In operation, the first robotic arm 310 transfers the culture dish 700 to be tested on the first storage rack 210 to the barcode scanning module 400 for scanning, and then transfers the scanned culture dish 700 to the biological sample counter 500 for calculation. When the number of biological samples in the culture dish 700 is greater than the threshold, the first robotic arm 310 transfers the culture dish 700 to the empty first storage rack 210. When the number of biological samples in the culture dish 700 is less than the threshold, the second robotic arm 320 transfers the culture dish 700 to the second rotating stack 600.

[0057] In this embodiment, the efficiency of classifying the culture dish 700 is further improved through the coordinated operation of the first robotic arm 310 and the second robotic arm 320.

[0058] In some embodiments, the intelligent biological sample sorting system further includes an abnormal dish stack 800 located near the barcode scanning module. When the barcode scanning module 400 detects an abnormality in a culture dish 700 to be inspected, the first robotic arm 310 or the second robotic arm 320 transfers the culture dish 700 to the abnormal dish stack 800.

[0059] In yet another embodiment of the present invention, a method for intelligent sorting of biological samples is provided. This method is implemented in an intelligent biological sample sorting system, with reference to... Figures 1 to 8 As shown, the method includes the following steps: S100: Place the culture dish 700 to be tested on the first storage plate rack 210.

[0060] In this step, the placement order of the culture dishes 700 is such that when a first storage rack 210 is full of culture dishes 700, the adjacent first storage rack 210 is not filled with culture dishes 700.

[0061] S200: The lifting unit 240 lifts the culture dish 700 in the first storage rack 210 until the culture dish 700 moves to the discharge port 2442 of the discharge unit 250.

[0062] S300: The discharge unit 250 drives the petri dish 700 located at the discharge port 2442 into the discharge area.

[0063] In this step, the discharge scanning unit 280 scans the information identification code on the top cover of the culture dish 700 in advance.

[0064] S400: The transfer robot 300 transfers the culture dish 700 on the discharge area to the barcode scanning module 400 for scanning.

[0065] It should be noted that if a scanning abnormality occurs in step S300 or S400, the transfer robot 300 will directly transfer the culture dish 700 to the abnormal dish stack 800.

[0066] S500: The transfer robot 300 transfers the scanned culture dish 700 into the biological sample counter 500 for counting.

[0067] S600: When the number of biological samples in the culture dish 700 is greater than the threshold, the transfer robot 300 transfers the culture dish 700 to the empty first storage rack 210. When the biological sample counter 500 calculates that the number of biological samples in the culture dish 700 is less than the threshold, the transfer robot 300 transfers the culture dish 700 to the second rotating stack 600.

[0068] Repeat steps S200-S600 until all culture dishes 700 are counted and sorted.

[0069] The above description is merely a specific implementation of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
