Description

Technical Field

[0001] The present application relates to the technical field of microbial sample processing devices, for example, to an inoculation device and a microbial sample pre-processing system. Background Art

[0002] At present, in the field of microbial testing, traditional microbial testing is performed by personnel, who can only operate one inoculation loop at a time. Sterilization is required before sample extraction and after culture dish inoculation. The average sterilization operation time is 15s to 30s. The long operation time affects operational efficiency.

[0003] Related technologies disclose the use of mechanical automation for inoculation, using a robotic arm to clamp the inoculation loop, sterilizing the inoculation loop, extracting the sample after sterilization, and then clamping the inoculation loop with the robotic arm to inoculate the culture dish, which is then sterilized again after inoculation.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The related art uses a mechanical automation method for inoculation. Although the efficiency can be improved, there is no way to clean the inoculation loop, which easily causes ash to accumulate on the surface, affecting the extraction and inoculation effects.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The disclosed embodiments provide an inoculation device and a microbial sample pretreatment system to improve the extraction and inoculation effects of an inoculation loop.

[0009] An embodiment of the present disclosure provides an inoculation device, which includes: a workbench provided with a connecting assembly; a rotating frame provided on the connecting assembly and capable of being rotatably connected relative to the connecting assembly; an inoculation ring rotatably connected to the rotating frame; an operating station provided on the workbench and corresponding to the rotating frame, and the number of the operating stations is multiple, and the multiple operating stations are arranged at intervals along the circumference of the rotating frame for cooperating with the inoculation ring, and the rotating frame drives the inoculation ring to rotate axially around the rotating frame so that the inoculation ring cooperates with different operating stations respectively, and the multiple operating stations include a first operating station and a second operating station; wherein, the inoculation ring can rotate relative to the rotating frame in a first position and a second position, and when the inoculation ring is in the first position, there is a first angle between the inoculation ring and the vertical direction, and the head of the inoculation ring corresponds to the first operating station; when the inoculation ring is in the second position, there is a second angle between the inoculation ring and the vertical direction, and the head of the inoculation ring corresponds to the second operating station, and the second angle is greater than the first angle.

[0010] The disclosed embodiments further provide a microbial sample pretreatment system, which includes an inoculation device as described in any one of the above embodiments.

[0011] The inoculation device and microbial sample pretreatment system provided by the embodiments of the present disclosure can achieve the following technical effects:

[0012] The turret is rotatably connected to the workbench and is equipped with an inoculating loop. This allows the turret to drive the inoculating loop to rotate relative to the workbench. Specifically, the turret drives the inoculating loop to rotate axially around the turret, allowing the inoculating loop to change position with the turret. Multiple operating stations are spaced apart along the circumference of the turret on the workbench. As the inoculating loop rotates with the turret, it can coordinate with different operating stations. The inoculating loop can rotate relative to the turret, meaning its angle can be adjusted to accommodate different inoculating stations, allowing the loop's head to coordinate with different stations, thereby enabling multi-process operation of the inoculating loop. Thus, the inoculating device of the disclosed embodiment not only enables mechanically automated ring connection but also allows for multiple operating stations, such as sterilization and cleaning stations. Corresponding operating stations can also be configured to meet other needs. This allows for cleaning of the inoculating loop to prevent ash accumulation and, through the provision of other operating stations, allows for a full-process inoculation process, improving both efficiency and effectiveness.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0044] For the convenience of description, the following text of this application is as follows Figure 1 shown.

[0045] Combine Figures 10 to 14 As shown, an embodiment of the present disclosure provides an inoculation device 50, which includes a workbench 100, a rotating frame 51, an inoculation ring 52, and an operating station. The rotating frame 51 is provided on the workbench 100 and is rotatably connected to the workbench 100. The inoculation ring 52 is provided on the rotating frame 51; the operating stations are provided on the workbench 100 and correspond to the rotating frame 51. There are multiple operating stations, which are arranged at intervals along the circumference of the rotating frame 51 for cooperating with the inoculation ring 52. The rotating frame 51 drives the inoculation ring 52 to rotate around the axial direction of the rotating frame 51, so that the inoculation ring 52 cooperates with different operating stations respectively.

[0046] In the embodiment of the present disclosure, the workbench 100 is used to install a rotating frame 51 and an inoculation station 602, and the rotating frame 51 can rotate relative to the workbench 100. The inoculation ring 52 is arranged on the rotating frame 51, and the rotating frame 51 can drive the inoculation ring 52 to rotate around the axial direction of the rotating frame 51, so that the inoculation ring 52 can cooperate with multiple inoculation stations 602 corresponding to the rotating frame 51, so that the inoculation ring 52 can perform different operations. This can not only improve the degree of automation of the inoculation work and improve the inoculation efficiency, but also set up multiple different operating stations according to needs, such as a sterilization station 604 can be set to sterilize the inoculation ring 52 after inoculation, or a cleaning station 603 can be set to clean the sterilized inoculation ring 52 to avoid the accumulation of ash. This can improve the effect and efficiency of inoculation.

[0047] Alternatively, as Figure 10As shown, the plurality of operating stations include at least two of a sample extraction station 601 , an inoculation station 602 , a sterilization station 604 and a cleaning station 603 .

[0048] In the disclosed embodiment, two or more operating stations can be provided. The sample extraction station 601 is used to extract samples using the inoculating loop 52. The inoculation station 602 is used to cooperate with the inoculating loop 52 for inoculation. The sterilization station 604 is used to cooperate with the inoculating loop 52 to sterilize the inoculating loop 52. The cleaning station 603 is used to clean the inoculating loop 52 to avoid the problem of ash.

[0049] Optionally, when the multiple operating stations include a sample extraction station 601, an inoculation station 602, a sterilization station 604, and a cleaning station 603, the sample extraction station 601, the inoculation station 602, the cleaning station 603, and the sterilization station 604 are sequentially spaced along the circumference of the rotating frame 51. This can be understood as follows: starting from the sample extraction station 601, the inoculation loop 52 cooperates with the sample extraction station 601 in sequence to extract the sample, then rotates to the inoculation station 602 for inoculation. After inoculation, the inoculation loop 52 rotates to the cleaning station 603 for cleaning, and then rotates to the sterilization station 604 for sterilization. After sterilization, the inoculation loop 52 rotates back to the sample extraction station 601 for sample extraction. This improves both the efficiency of inoculation and the cleaning effect of the inoculation loop 52, thereby improving the effectiveness of inoculation.

[0050] Optionally, there are multiple inoculation rings 52 , and the multiple inoculation rings 52 are sequentially spaced apart along the circumference of the rotating frame 51 .

[0051] In the embodiment of the present disclosure, the number of inoculation rings 52 can also be set to multiple, so that when the rotating frame 51 rotates, multiple inoculation rings 52 can cooperate with different operating stations respectively, further improving work efficiency.

[0052] Optionally, the number of inoculation loops 52 is the same as the number of operating stations, and each inoculation loop 52 can be coordinated with an operating station when the inoculation loops 52 rotate. This eliminates the need for too many inoculation loops 52, saving costs. Furthermore, when the inoculation device 50 is in operation, each inoculation loop 52 can be coordinated with an operating station, allowing multiple operations to be performed simultaneously, thereby improving work efficiency.

[0053] Optionally, when the multiple operating stations include a sample extraction station 601, an inoculation station 602, a sterilization station 604 and a cleaning station 603, the number of inoculation loops 52 is four. In this way, when the inoculation device 50 is working, each operating station has an inoculation loop 52, and the inoculation work does not require waiting, thereby improving work efficiency.

[0054] Optionally, the inoculation ring 52 is rotatably connected to the rotating frame 51, and the inoculation ring 52 can rotate relative to the rotating frame 51 between a first position and a second position. When the inoculation ring 52 is in the first position, there is a first angle between the inoculation ring 52 and the vertical direction, and the head of the inoculation ring 52 can correspond to the first inoculation station; when the inoculation ring is in the second position, there is a second angle between the inoculation ring 52 and the vertical direction, and the head of the inoculation ring 52 corresponds to the second inoculation station, wherein the second angle is greater than the first angle, and the multiple inoculation stations include the first inoculation station and the second inoculation station.

[0055] In the disclosed embodiment, the height of the inoculation station 602 is less than the height of the rotating frame 51, which makes it easier for the head of the inoculation ring 52 to cooperate with different operating stations. The inoculation ring can rotate relative to the rotating frame, which improves the operational flexibility of the inoculation ring. The angle of the inoculation ring can be adjusted according to the position and angle of different operating stations, so that the inoculation ring can cooperate with different operating stations. For example, the station that does not require a high angle for the inoculation ring can be defined as the first inoculation station. The inoculation ring can correspond to the first inoculation station, for example, it can be inserted into the first inoculation station without moving relative to the first inoculation station. Therefore, the first angle of rotation of the inoculation ring corresponding to the first operating station can be smaller. The second inoculation station can be an inoculation station that requires operation. At this time, the angle between the inoculation ring and the vertical direction is larger, for example, culture dishes or slides can be inoculated or smeared.

[0056] Optionally, the first operating station includes at least one of a sample extraction station, a sterilization station, and a cleaning station, and the second operating station includes an inoculation station. When the inoculation loop is in the first position, the head of the inoculation loop can be inserted into the first operating station. The first inoculation station is a station that does not require a high angle for the inoculation loop. The inoculation loop only needs to be inserted into the first inoculation station. Therefore, the first angle of rotation of the inoculation loop corresponding to the first operating station can be small. The second inoculation station is an inoculation station that requires operation. At this time, the angle between the inoculation loop and the vertical direction is large, which is convenient for inoculating or smearing culture dishes or slides.

[0057] Optionally, when the inoculation ring 52 is rotated to the first position relative to the rotating frame 51, the inoculation ring 52 can correspond to the sample extraction station 601, the sterilization station 604 or the cleaning station 603. These operating stations have smaller angle requirements for the inoculation ring 52, and the head of the inoculation ring 52 can be inserted into the corresponding operating station to achieve operation. When the inoculation ring is rotated to the second position, the head of the inoculation ring 52 corresponds to the inoculation station 602, and the inoculation station 602 requires the inoculation ring 52 to perform marking or smear operations, which requires a higher range of motion and angle of motion for the inoculation ring 52. Therefore, when the inoculation ring 52 is in the second position, the angle between the inoculation ring 52 and the vertical direction is larger, which makes the inoculation ring 52 more inclined, thereby facilitating the inoculation ring 52 to perform marking or smear operations.

[0058] It should be noted that the first operating station and the second operating station can also be other stations. For example, the second operating station can also include one or more of the cleaning work, sterilization station and extraction station. In actual use, the angle of the inoculation loop moved to the corresponding position can be adjusted according to the setting position and setting angle of different inoculation stations, so that the inoculation loop can cooperate with different operating stations to improve the flexibility of use of the inoculation device.

[0059] Optionally, the inoculating ring is vertically rotatable relative to the turret, allowing the inoculating ring to adjust its angle relative to the vertical. Optionally, the inoculating ring is rotatably connected to the outer edge of the turret, or the inoculating ring is rotatably connected to the turret near the outer edge, so that the inoculating ring has sufficient space to rotate and avoid interference with the connecting component.

[0060] Optionally, the first angle ranges from 0 degrees to 10 degrees. When the inoculating loop 52 corresponds to the sample extraction station 601, the sterilization station 604, or the cleaning station 603, the inoculating loop 52 can be set vertically or at a small angle to the vertical direction, as long as it can be inserted into the corresponding operating station. The first angle should not be too large. If the first angle is too large, the horizontal distance between the operating station and the rotating frame 51 is increased, the size of the inoculating device 50 is increased, and it is not convenient to install and set it.

[0061] Optionally, the second angle ranges from 30 degrees to 80 degrees, which increases the horizontal distance between the inoculation station 602 and the rotating frame 51, facilitates the setting of the inoculation station 602, and also facilitates the coordination between the head of the inoculation ring 52 and the inoculation station 602.

[0062] Optionally, the height of the operating station is smaller than the height of the rotating frame 51, the head of the inoculation ring 52 is located below the inoculation ring 52, and the tail of the inoculation ring 52 is located above the inoculation ring 52, and the inoculation ring 52 can rotate in the up and down directions relative to the rotating frame 51. When the inoculation ring 52 moves from the first position to the second position, the tail of the inoculation ring 52 moves downward and toward the rotating frame 51, and the head of the inoculation ring 52 moves upward and away from the axis of the rotating frame 51, so that the inoculation ring 52 is tilted. This ensures that the inoculation station 602 is at a horizontal distance from the rotating frame 51, facilitates the coordination between the inoculation station 602 and other sample loading devices or sample collecting devices 321, facilitates the movement of the inoculation station 602 itself, and facilitates marking or smearing of the head of the inoculation ring 52.

[0063] Optionally, the inoculation station 602 is located outside the projection of the rotating frame 51 on the workbench 100 from top to bottom, and the minimum horizontal distance between the inoculation station 602 and the outer edge of the rotating frame 51 is greater than the minimum horizontal distance between the sample extraction station 601, the sterilization station 604, or the cleaning station 603 and the outer edge of the rotating frame 51. It can be understood that the inoculation station 602 is the farthest horizontal distance from the rotating frame 51. Therefore, when the inoculation loop is in the second position, the second angle is greater than the first angle. The inoculation station 602 is the farthest horizontal distance from the rotating frame 51, and the workbench 100 has sufficient space for setting up operating stations. In addition, the inoculation loop 52 is set at an angle, which increases the range of motion of the inoculation loop 52 and improves the effectiveness of streaking and smearing.

[0064] Alternatively, as Figure 12 As shown, the inoculation device 50 also includes a connecting assembly and a boss 56. The connecting assembly is connected between the rotating frame 51 and the workbench 100, and the rotating frame 51 can rotate relative to the connecting assembly; the boss 56 is arranged on the connecting assembly, located on one side of the rotating frame 51, and corresponds to the inoculation station 602. The boss 56 protrudes from the circumferential outer wall surface of the rotating frame 51. When the inoculation ring 52 rotates around the axial direction of the rotating frame 51 and moves toward the inoculation station 602, the boss 56 contacts the inoculation ring 52 and lifts the head of the inoculation ring 52, so that the inoculation ring 52 moves from the first position to the second position.

[0065] In the embodiment of the present disclosure, the connecting assembly is used to realize the connection between the rotating frame 51 and the workbench 100 . The rotating frame 51 can rotate relative to the connecting assembly, thereby realizing the rotational connection between the rotating frame 51 and the workbench 100 . The boss 56 is provided on the connecting assembly, so that when the rotating frame 51 rotates, the boss 56 will not rotate. The boss 56 protrudes from the circumferential outer wall of the rotating frame 51, and the boss 56 corresponds to the inoculation station 602. In this way, when the inoculation ring 52 moves from other operating stations toward the inoculation station 602, the inoculation ring 52 will contact the boss 56. Since the inoculation ring 52 is rotatably connected to the rotating frame 51, under the action of the boss 56, the inoculation ring 52 can rotate, and thus the inoculation ring 52 can be rotated from the first position to the second position. When the inoculation ring 52 completes the inoculation and rotates away from the inoculation station 602, the inoculation ring 52 is no longer in contact with the boss 56, and the inoculation ring 52 returns to the first position under its own gravity. In this way, there is no need to set up a driving structure to realize the rotation of the inoculation ring 52 relative to the rotating frame 51, which saves energy consumption and is more efficient.

[0066] Optionally, the inoculation ring 52 includes an inoculation ring body and a roller 527. The roller 527 is arranged on one side of the inoculation ring body. When the inoculation ring 52 contacts the boss 56, the roller 527 contacts the boss 56 and rolls along the boss 56. When the inoculation ring 52 moves to the second position, the roller 527 separates from the boss 56.

[0067] In the embodiment of the present disclosure, the roller 527 is arranged on one side of the inoculation ring 52, so that when the inoculation ring 52 contacts the boss 56, the inoculation ring 52 contacts the boss 56 through the roller 527, and the roller 527 can roll along the boss 56, thereby increasing the contact area between the inoculation ring 52 and the boss 56, buffering the impact force of the boss 56 on the inoculation ring 52, and the roller 527 has a certain height. When the roller 527 contacts the boss 56, it can quickly increase the inclination angle of the inoculation ring 52, thereby increasing the speed at which the inoculation ring 52 moves from the first position to the second position, thereby improving the inoculation efficiency.

[0068] Optionally, the rotating frame 51 includes a rotating frame body, a fixed frame 512 and a rotating shaft, and the rotating frame body defines a plurality of mounting positions 511 arranged at circumferential intervals along the rotating frame body; the fixed frame 512 is arranged at the outer end of the mounting position 511, and the fixed frame 512 is constructed with a rotating groove 513, and the two opposite side walls of the rotating groove 513 extend in the vertical direction. The inoculation ring 52 rotates in the rotating groove 513, and the two opposite side walls of the rotating groove 513 are provided with a first rotating hole, and the inoculation ring is provided with a second rotating hole, and the second rotating hole corresponds to the first rotating hole; the rotating shaft passes through the first rotating hole and the second rotating hole to enable the inoculation ring to rotate in the rotating groove 513.

[0069] In the disclosed embodiment, the mounting position 511 is used to mount the inoculating ring 52. The fixing frame 512 is located at the outer end of the mounting position 511. The fixing frame 512 is configured with a rotation groove 513. The two opposing side walls of the rotation groove 513 extend in the vertical direction. Thus, the front and rear ends and the upper end of the rotation groove 513 are open. The inoculating ring 52 is rotated in the rotation groove 513 via a rotating shaft, thereby enabling the inoculating ring 52 to rotate in the vertical direction. Moreover, the fixing frame 512 is located at the outer end of the mounting position 511, so that the rotation of the inoculating ring 52 is not hindered by the rotating frame 51, thereby improving the degree of freedom of rotation.

[0070] Optionally, the turret body includes a center plate and a mounting plate. The mounting plate is connected to the outside of the center plate and extends away from the center plate. There are multiple mounting plates, each spaced apart along the circumference of the center plate. Each mounting plate is configured with mounting positions 511. This spacing between adjacent mounting plates away from the center plate reduces the weight and cost of the turret 51, minimizes interference with the rotation of the inoculating loop 52, and improves smoothness of rotation.

[0071] Optionally, the inoculation device 50 also includes a first magnetic member 53 and a first magnetic matching member 531. The first magnetic member 53 is arranged at the tail of the inoculation ring 52 and is located on one side of the rotating shaft. When the inoculation ring 52 is in the second position, the first magnetic member 53 extends in the vertical direction; the first magnetic matching member 531 is arranged on the rotating frame 51 and corresponds to the inoculation station 602. When the inoculation ring 52 moves to the inoculation station 602 and rotates to the second position, the first magnetic member 53 corresponds to the first magnetic matching member 531, and a repulsive magnetic force is formed between the first magnetic member 53 and the first magnetic matching member 531 to apply a downward force to the head of the inoculation ring 52.

[0072] In the disclosed embodiment, a first magnetic member 53 is provided at the tail of the inoculation ring 52. The first magnetic member 53 and the first magnetic matching member 531 generate a repulsive magnetic force, which can further apply force to the inoculation ring 52 so that the inoculation ring 52 can contact the device to be inoculated 50 of the inoculation station 602, thereby improving the accuracy of the marking. In this way, the boss 56 increases the main force on the movement of the inoculation ring 52, and the first magnetic member 53 can fine-tune the position of the inoculation ring 52 to ensure the accuracy of the position of the movement of the inoculation ring 52. In addition, the first magnetic member 53 itself has a certain weight. When the inoculation ring 52 moves from the first position to the second position, the first magnetic member 53 can act as a moving counterweight, thereby improving the movement efficiency and accuracy of the inoculation ring 52.

[0073] Optionally, both the first magnetic component 53 and the first magnetic matching component 531 are magnets.

[0074] Optionally, the inoculation device 50 also includes a first limiting column 532 and a second limiting column 533, the first limiting column 532 is arranged at the tail of the inoculation ring 52 and is located on one side of the rotating shaft; the second limiting column 533 is arranged on the rotating frame 51 and corresponds to the inoculation station 602; wherein, when the inoculation ring 52 moves to the inoculation station 602 and rotates to the second position, the first limiting column 532 corresponds to the second limiting column 533 and is arranged at intervals; when the first limiting column 532 and the second limiting column 533 are in contact, the head of the inoculation ring 52 is restricted from moving upward.

[0075] In the disclosed embodiment, the tail of the inoculation ring 52 is further provided with a first limiting post 532, and the rotating frame 51 is provided with a second limiting post 533. When the inoculation ring 52 rotates to the second position, the first limiting post 532 and the second limiting post 533 are arranged in correspondence and at intervals. When the first limiting post 532 and the second limiting post 533 come into contact, the head of the inoculation ring 52 is restricted from rotating upward. In this way, the first limiting post 532 and the second limiting post 533 limit the rotation range of the inoculation ring 52, thereby preventing the inoculation ring 52 from rotating too far and causing damage to the inoculation ring 52. In addition, the first limiting post 532 can also act as a counterweight, increasing the weight of the tail of the inoculation ring 52 and increasing the speed at which the inoculation ring 52 moves from the first position to the second position.

[0076] Optionally, the first limiting post 532 is located on a side of the first magnetic component 53 away from the rotation axis.

[0077] Optionally, the length of the first limiting column 532 is smaller than the length of the first magnetic member 53 .

[0078] Optionally, the inoculation device 50 also includes a detection device 534, which is arranged on the rotating frame 51 and corresponds to the inoculation station 602, and is used to detect the position information of the inoculation ring 52 moving to the inoculation station 602; the controller is electrically connected to the detection device 534, and is used to receive the position information of the inoculation ring 52 at the inoculation station 602.

[0079] In the embodiment of the present disclosure, the detection device 534 can detect whether the inoculation ring 52 is rotated to the second position and detect the rotation accuracy of the inoculation ring 52. The detection device 534 sends the detection information to the controller, and the controller can issue prompts or control the movement of related equipment based on the detection information.

[0080] Optionally, the inoculation device 50 further includes a prompting device electrically connected to the controller, and the controller is configured to control the prompting device to operate to remind the user when the inoculation ring 52 does not move to the second position.

[0081] For example, the prompting device may be a light, an alarm, etc.

[0082] Optionally, a detection device 534 corresponds to the second limiting post 533 and is used to detect the position of the first limiting post 532. Thus, when the first limiting post 532 deviates from the preset position, the detection device 534 can detect that the inoculating loop 52 has not moved to the second position and send a message to the controller. The detection device 534 can be a photoelectric detection device 534.

[0083] Optionally, the inoculation device 50 also includes an upper shell 55, which is covered above the rotating frame 51, and the rotating frame 51 is rotatably arranged in the upper shell 55; wherein, the upper shell 55 defines a cylindrical space with an opening at the bottom, and the side wall of the upper shell 55 is provided with a notch 551, which is connected to the opening, and the notch 551 corresponds to the boss 56, so that when the inoculation ring 52 moves toward the inoculation station 602, the notch 551 can avoid the inoculation ring 52 from rotating from the first position to the second position, and when the inoculation ring 52 abuts against the upper side wall of the notch 551, the head of the inoculation ring 52 is restricted from moving upward.

[0084] In the disclosed embodiment, the rotating frame 51 is located in the upper shell 55. On the one hand, the upper shell 55 can protect the rotating frame 51 and the inoculation ring 52 and reduce the accumulation of dust. On the other hand, the upper shell 55 can play a certain role in limiting the inoculation ring 52. When the inoculation ring 52 moves to an operating station other than the inoculation station 602, the side wall of the upper shell 55 can play a certain role in limiting the inoculation ring 52, thereby preventing the inoculation ring 52 from rotating at a large angle and causing the inoculation ring 52 to contact with other devices and damage the inoculation ring 52. When the inoculation ring 52 moves from the previous operating station toward the inoculation station 602, a notch 551 is provided on the side wall of the upper shell 55. The notch 551 can avoid the inoculation ring 52 and provide sufficient space for the rotation of the inoculation ring 52, so that the inoculation ring 52 can rotate from the first position to the second position. When the inoculation ring 52 abuts against the upper side wall of the notch 551, the head of the inoculation ring 52 is restricted from moving upward, so that the upper shell 55 can play a limiting role, preventing the inoculation ring 52 from rotating too far, thereby ensuring the accuracy of the inoculation work.

[0085] Optionally, the inoculation station 602 includes a tray 231, which is arranged on one side of the rotating frame 51. The inoculation ring 52 is rotated to correspond to the inoculation station 602, and when the inoculation ring 52 is rotated to the second position, the device to be inoculated 50 carried by the tray 231 abuts against the head of the inoculation ring 52, and applies an upward force to the inoculation ring 52 to separate the inoculation ring 52 from the boss 56.

[0086] In the disclosed embodiment, after the inoculation ring 52 is rotated horizontally and vertically to its proper position, the head of the inoculation ring 52 contacts the device to be inoculated 50 carried by the tray 231, so that the inoculation ring 52 can scribe or smear the device to be inoculated 50. At this time, the upward force applied by the device to be inoculated 50 on the head of the inoculation ring 52 can raise the height of the inoculation ring 52, thereby separating the inoculation ring 52 from the boss 56. In this way, except for the two contact points with the device to be inoculated 50 and the rotating shaft, the other parts of the inoculation ring 52 are all suspended in the air, thereby reducing the resistance to the rotation of the inoculation ring 52 and improving the convenience of the inoculation ring.

[0087] Optionally, the inoculation device 50 also includes a support member 54, a second magnetic member 541 and a second magnetic matching member, one end of the support member 54 is connected to the rotating frame 51, and the other end of the support member 54 extends to the top and front of the rotating groove 513; the second magnetic member 541 is arranged on the side wall of the support member 54 facing the rotating frame 51; the second magnetic matching member is arranged on the inoculation ring; when the second magnetic member 541 is adsorbed with the second magnetic matching member, the inoculation ring is restricted from rotating relative to the rotating frame to fix the inoculation ring in the first position.

[0088] In the embodiment of the present disclosure, one end of the support member 54 is fixed to the rotating frame 51, so that the support member 54 can rotate with the rotating frame 51. When the inoculation ring 52 moves from the second position toward the first position, the second magnetic member 541 and the second magnetic matching member are attracted to each other, so that the inoculation ring 52 can be fixed in the first position to prevent the inoculation ring 52 from rotating. In addition, the other end of the support member 54 and the other end of the support frame can extend to the top and front of the rotating groove 513, and can also limit the inoculation ring 52 to prevent the inoculation ring 52 from rotating too far. Specifically, the second magnetic matching member is provided on the side wall of the inoculation ring away from the rotating frame.

[0089] Optionally, the tray 231 is movably arranged on the workbench 100, and the tray 231 can move in the left and right directions and the front and back directions. In this way, when the inoculation loop is inoculated, the tray moves in different directions, so that the inoculation loop can mark or smear a larger range in the device to be inoculated.

[0090] Optionally, a tray 231 is movably mounted on one side of the inoculation device 50. The tray 231 can cooperate with the culture dish loading device 21 or the glass slide loading device 22 to carry the culture dish 40 or the glass slide. In the disclosed embodiment, the tray 231 can carry both the culture dish 40 and the glass slide. This allows the culture dish 40 or the glass slide to be placed in the tray 23 according to processing requirements. The tray 23 then cooperates with the inoculation device 50 for streaking or smearing. In this way, both the glass slide and the culture dish 40 can cooperate with the inoculation device 50, thereby improving the system's versatility and ease of use.

[0091] Optionally, the inoculation device 50 also includes an operating table 24, which is movably arranged on the workbench 100, and a tray 231 is rotatably arranged above the operating table 24; wherein, the upper wall surface of the tray 231 is constructed with a culture dish loading slot 2316 and a slide loading slot 2312, and the slide loading slot 2312 is located on the inner side of the culture dish loading slot 2316, the culture dish loading slot 2316 is used to load the culture dish 40, and the slide loading slot 2312 is used to load the slide.

[0092] In the disclosed embodiment, the operating table 24 is movably mounted on the workbench 100, so that the operating table 24 can drive the tray 231 to move relative to the workbench 100. The tray 231 is rotatably mounted above the operating table 24, so that the tray 231 can also rotate relative to the operating table 24, making the movement of the tray 231 more flexible, thereby improving the flexibility of streaking or smearing to meet the streaking and smearing requirements of different culture dishes 40 or slides.

[0093] Optionally, the operating table 24 is slidably connected to the workbench 100. Specifically, the operating table 24 can move in the left and right directions and the front and back directions relative to the workbench 100, and the tray 231 can drive the culture dish 40 or the slide to translate or rotate, thereby improving the flexibility of the tray 231 and improving the marking or smearing effect.

[0094] Optionally, the tray 231 includes a first reinforcing rib 2311, a second reinforcing rib 2313, a third reinforcing rib 2314 and a fourth reinforcing rib 2315, wherein the upper wall portion of the first reinforcing rib 2311 is recessed to form a slide loading slot 2312; the second reinforcing rib 2313 is cross-arranged with the first reinforcing rib 2311 and connected to the middle portion of the first reinforcing rib 2311; the third reinforcing rib 2314 is connected to one end of the first reinforcing rib 2311; and the fourth reinforcing rib 2315 is connected to the other end of the first reinforcing rib 2311; wherein the second reinforcing rib 2313, the third reinforcing rib 2314 and the fourth reinforcing rib 2315 define a culture dish loading slot 2316.

[0095] In the disclosed embodiment, the upper wall surface of the first reinforcing rib 2311 is recessed to form a slide loading slot 2312, which is used to place slides to achieve slide positioning, loading, and operational stability. The shape and size of the slide loading slot 2312 match the shape and size of the slide to improve the stability of the slide setting. The second reinforcing rib 2313 is cross-connected to the middle of the first reinforcing rib 2311, and the third reinforcing rib 2314 and the fourth reinforcing rib 2315 are respectively located at the two ends of the first reinforcing rib 2311. In this way, the first reinforcing rib 2311, the second reinforcing rib 2313, the third reinforcing rib 2314, and the fourth reinforcing rib 2315 increase the cross-sectional area of ​​the tray 231, thereby defining a culture dish loading slot 2316. The shape and size of the culture dish loading slot 2316 match the shape and size of the culture dish 40 to achieve loading and operational stability of the culture dish 40. The tray 231 of the embodiment of the present disclosure can be loaded with both culture dishes 40 and glass slides, thus realizing the reuse of the tray 231. This enables the system to perform both streaking of the culture dishes 40 and smearing of the glass slides without the need to set up multiple trays 231, thereby improving operational efficiency. In addition, during the microbiological inspection process, the inoculation and streaking of the culture dishes 40 and the smearing of the glass slides are not performed simultaneously. Therefore, the reusable tray 231 of the present application can be applied to different inspection processes. The tray 231 can be rotated and translated, so that the tray 231 can be used for a variety of different inoculation requirements of the culture dishes 40 or glass slides, thereby increasing the use function.

[0096] Optionally, the length of the slide loading slot 2312 is aligned with the length of the first reinforcing rib 2311, and the second, third, and fourth reinforcing ribs 2313, 2314, and 2315 are spaced apart along the length of the first reinforcing rib 2311. Thus, the tray 231 is not a completely solid structure, and gripping grooves 2317 are formed between adjacent reinforcing ribs. Thus, the tray 231 has reserved gripping grooves 2317 to provide space for the culture dish 40 to be placed on or removed from the tray 231. This allows a gripper for transferring the culture dish 40 to be inserted into the gripping grooves 2317, thereby improving gripping stability of the culture dish 40.

[0097] Optionally, the streaking smear device 23 further includes a positioning pin 2318, which is protruding from the outside of the culture dish loading slot 2316. When the culture dish 40 is loaded into the culture dish loading slot 2316, the positioning pin 2318 positions the culture dish 40 to prevent the culture dish 40 from shifting.

[0098] Optionally, there are multiple positioning pins 2318, which are sequentially spaced along the circumference of the culture dish loading slot 2316 to improve the multi-directional positioning effect on the culture dish 40. For example, Figure 7As shown, a plurality of positioning pins 2318 are respectively provided on the second reinforcing rib, the third reinforcing rib and the fourth reinforcing rib.

[0099] Alternatively, as Figure 11 As shown, the inoculation device 50 also includes an image recognition component and a display device. The image recognition component includes a light source 57, a prism 571, and a lens 572. The image recognition component corresponds to the sample extraction station 601. When the inoculation loop 52 corresponds to the sample extraction station 601, the head of the inoculation loop 52 is located between the light source 57 and the prism 571. The prism 571 is used to refract the light emitted by the light source 57 so that the lens 572 can obtain image information of the head of the inoculation loop 52. The display device is electrically connected to the lens 572 and is used to display the image information of the head of the inoculation loop 52. The light source 57 is provided with a reference device, which is used to compare the image information of the head of the inoculation loop 52 to determine whether the inoculation loop 52 has been successfully extracted.

[0100] In the disclosed embodiment, the head of the inoculating loop 52 can correspond to the light source 57, and the light source 57 can emit light to illuminate the head of the inoculating loop 52. Here, when the inoculating loop 52 rotates to the inoculation station 602, the inoculating loop 52 should have extracted a sample from the sample extraction station 601, and therefore, the head of the inoculating loop 52 should have a sample. The head of the inoculating loop 52 is located between the light source 57 and the prism 571. The prism 571 can change the direction of the light emitted by the light source 57, so that the lens 572 can capture a picture of the inoculating loop 52 even if the light source 57 and the inoculating loop 52 are not in a straight line. This increases the flexibility of the installation position of the lens 572 and reduces the size of the inoculating device 50. It is understood that the prism can also be omitted, and the head of the inoculating loop 52 can be located between the light source 57 and the lens 572, and the three can be in a straight line. In this way, a picture of the head of the inoculating loop 52 can also be captured.

[0101] Light source 57 is equipped with a reference device. When lens 572 captures a picture of the head of inoculating loop 52, both the picture of the head of inoculating loop 52 and the reference device are displayed on the display. By comparing the picture of the head of inoculating loop 52 with the reference device, it is possible to determine whether the extraction was successful. Furthermore, the position and angle of inoculating loop 52 can also be identified and determined using the image information, thereby improving the accuracy of inoculation of inoculating loop 52.

[0102] Optionally, the reference device is a grid line having multiple grids. When the inoculating loop 52 successfully extracts, a liquid film appears at the head of the inoculating loop 52. Due to the refraction of the liquid film, the grid lines appear curved or distorted. At this point, the inoculating loop 52 can be judged to have been successfully extracted, and the next step of inoculation can be performed. If no liquid film appears and the grid lines do not curve or distort, the extraction is judged to have been unsuccessful, and the inoculating loop 52 can be controlled to return to the sample extraction station 601 for extraction. In addition, the position of the head of the inoculating loop 52 within the grid lines can be used to determine whether the inoculating loop 52 has been moved into position.

[0103] Optionally, the size of the liquid film is related to the size of the inoculation loop 52 , and inoculation loops 52 of different sizes can be set with different reference sizes to achieve quantitative extraction and provide standardized sample liquid for subsequent microbiological testing.

[0104] Optionally, the connecting assembly includes a lifting rod 581, which is movably arranged on the workbench 100, and one end of the lifting rod 581 is connected to the rotating frame 51, which can drive the rotating frame 51 to rise and fall relative to the workbench 100; the inoculation device 50 also includes a first driving device, which is drivingly connected to the lifting rod 581 and is used to drive the lifting rod 581 to rise and fall.

[0105] In the disclosed embodiment, the lifting rod 581 can drive the rotating frame 51 to move up and down, thereby enabling the inoculation ring 52 of the rotating frame 51 to move in the up and down directions. In this way, after the inoculation ring 52 rotates to the second position, the lifting rod 581 drives the inoculation ring 52 to descend so that the inoculation ring 52 can contact the device to be inoculated 50. After the inoculation of the inoculation ring 52 is completed, the lifting rod 581 drives the inoculation ring 52 upward, and then the inoculation ring 52 rotates to the first position. In this way, when the inoculation ring 52 rotates with the rotating frame 51, it will not interfere with other equipment.

[0106] Optionally, the first driving device includes a guide rail, a movable part 582 and a first motor 583, the guide rail extends in the vertical direction; the movable part 582 is connected to the other end of the lifting rod 581 and can slide along the guide rail; the first motor 583 is connected to the movable part 582 to drive the movable part 582 to slide along the guide rail, thereby driving the lifting rod 581 to rise and fall.

[0107] In the embodiment of the present disclosure, the movable member 582 is connected to the lifting rod 581 , and the first motor 583 drives the movable member 582 to move along the guide rail, thereby enabling the lifting rod 581 to be raised and lowered.

[0108] Optionally, the lifting rod 581 passes through the workbench 100, with one end of the lifting rod 581 located above the workbench 100 and the other end of the lifting rod 581 located below the workbench 100. The guide rail, movable member 582, and first motor 583 are all located below the workbench 100. This provides sufficient space for installing a second drive device, thereby increasing the lifting stroke of the lifting rod 581 and ensuring the upward and downward movement of the inoculating loop 52.

[0109] Optionally, the connecting assembly includes a hollow platform 584, which is connected between one end of the lifting rod 581 and the rotating frame 51, and the hollow platform 584 is rotatably connected to the rotating frame 51; the inoculation device 50 also includes a second driving device, which is provided on the hollow platform 584 and is drivably connected to the rotating frame 51 to drive the rotating frame 51 to rotate relative to the hollow platform 584.

[0110] In the disclosed embodiment, the hollow platform 584 is connected between the lifting rod 581 and the rotating frame 51, and the rotating frame 51 can rotate relative to the hollow platform 584. The second driving device is fixed to the hollow platform 584 and then driven by the rotating frame 51, thereby driving the rotating frame 51 to rotate.

[0111] Optionally, an installation cavity is defined inside the hollow platform 584, and the second driving device includes a second motor 585 and a transmission device. The second motor 585 is fixed on the outside of the hollow platform 584, the transmission device is located in the installation cavity, and the transmission device is connected to both the second motor 585 and the rotating frame 51. The second motor 585 drives the transmission device to drive the rotating frame 51 to rotate around the axial direction of the rotating frame 51.

[0112] Optionally, the boss 56 is connected to the hollow platform 584 , so that the hollow platform 584 can fix the boss 56 to prevent the boss 56 from rotating with the rotating frame 51 .

[0113] Optionally, the cross section of the hollow platform 584 is circular to facilitate the cooperation between the hollow platform 584 and the second motor 585, the boss 56 and the transmission device.

[0114] Optionally, the hollow platform 584 is located below the turret 51, and the lifting rod 581 is located below the hollow platform 584. The inoculation device 50 further includes a connector 586, which is connected between the boss 56 and the hollow platform 584. The arrangement of the connector 586 enables the boss 56 to be located on one side of the circumference of the turret 51 and to protrude from the circumferential sidewall of the turret 51.

[0115] Optionally, the hollow platform 584 is coaxially disposed with the turret 51, and the outer diameter of the hollow platform 584 is smaller than that of the turret 51. The connector 586 includes a vertical plate segment and a horizontal plate segment connected to each other. The vertical plate segment extends vertically and is connected to the outer wall of the hollow platform 584. The horizontal plate segment is connected above the vertical plate segment and extends horizontally. The horizontal plate segment is located below the boss 56 and is connected to the boss 56. This allows the boss 56 to be connected to the hollow platform 584 and the boss 56, and allows the boss 56 to be installed in a predetermined position.

[0116] Optionally, the mounting position 511 of the rotating frame 51 includes a first mounting position, a second mounting position, and a third mounting position. When the first mounting position corresponds to the inoculation station 602, the first mounting position is located between the second mounting position and the third mounting position. When the second mounting position corresponds to the inoculation station 602, the first mounting position corresponds to the sample extraction station 601, and the third mounting position corresponds to the sterilization station 604. When the first mounting position corresponds to the inoculation station 602, the boss 56 is located outside the first mounting position and protrudes outside the first mounting position. Optionally, the boss 56 is curved and bends toward the rotating frame 51. One end of the boss 56 extends to the side of the second mounting position facing the first mounting position, and the other end of the boss 56 extends to the side of the third mounting position facing the first mounting position. In this way, when the rotating frame 51 drives the inoculation ring 52 to rotate, the inoculation ring 52 located at the second mounting position leaves the sample extraction station 601 and will promptly contact the boss 56, causing the inoculation ring 52 to rotate toward the second position. After rotating to the inoculation station 602, the inoculation ring 52 can rotate into position, so that the inoculation ring 52 has a certain amount of time and distance to rotate from the first position to the second position, providing a movement buffer to prevent the inoculation ring 52 from being suddenly lifted and causing damage to the inoculation ring 52. After the inoculation of the inoculation ring 52 is completed, the rotating frame 51 rotates, and the inoculation ring 52 can return to the first position along the boss 56, which also acts as a buffer to protect the inoculation ring 52.

[0117] Optionally, the horizontal width of the boss 56 along the radial direction of the rotating frame 51 gradually increases from the two ends to the middle position, so that when the inoculating ring 52 moves from the first position to the second position, the inoculating ring 52 gradually tilts, thereby preventing the inoculating ring 52 from moving too fast and causing damage to the inoculating ring 52. Similarly, it can also ensure that there is a certain amount of cushioning when the inoculating ring 52 moves from the second position to the first position, thereby preventing the inoculating ring 52 from being damaged.

[0118] Optionally, at the position where the boss 56 corresponds to the inoculation station 602 , the radial width of the boss 56 rotating frame 51 is the largest, so that the inclination angle is maximized when the inoculation ring 52 moves to the position corresponding to the inoculation station 602 .

[0119] Optionally, the boss 56 is crescent-shaped.

[0120] Alternatively, as Figure 13 As shown, the inoculation ring 52 includes an inoculation rod 521, an inoculation head 526, a pressing block 523 and an elastic member. The inoculation rod 521 is rotatably connected to the rotating frame 51, and one end of the inoculation rod 521 is configured with a mounting groove; the inoculation head 526 is detachably connected to the mounting groove for cooperating with the operating station; the pressing block 523 is movably located in the mounting groove, the pressing block 523 is provided with a first through hole, and the side wall of the mounting groove is correspondingly provided with a second through hole 525, and the inoculation head 526 can be inserted into the first through hole and the second through hole 525 at the same time; the elastic member is connected to the pressing block 523. between the tightening block 523 and the mounting groove; wherein, the tightening block 523 can move between a third position and a fourth position. When the tightening block 523 is in the third position, the inoculation head 526 is inserted into the first through hole and the second through hole 525 at the same time, the elastic member is in its original state, and the side wall of the first through hole limits the inoculation head 526 to prevent the inoculation head 526 from detaching from the mounting groove; when the tightening block 523 is in the fourth position, the elastic member undergoes elastic deformation, and the side wall of the first through hole releases the limit on the inoculation head 526, so as to facilitate the inoculation head 526 to detach from the mounting groove.

[0121] In the embodiment of the present disclosure, the inoculation head 526 is detachably connected to the inoculation rod 521, which facilitates the replacement of the inoculation head 526 without replacing the entire inoculation ring 52. After the inoculation head 526 of the embodiment of the present disclosure is inserted into the mounting groove, when no external force is applied to the clamping member, the elastic member is in its original state, and the elastic member causes the clamping block 523 to be located in the third position. At this time, the side wall of the first through hole corresponds to the second through hole 525, and the side wall of the first through hole of the clamping block 523 can apply force to the inoculation head 526. The inoculation head 526 also passes through the second through hole 525 of the mounting groove, so that the clamping block 523 and the mounting groove can clamp the inoculation head 526 that is simultaneously located in the first through hole and the second through hole 525, thereby realizing the connection between the inoculation head 526 and the inoculation rod 521. When it is necessary to disassemble the inoculation head 526, the pressing piece is pressed, and the first through hole moves, so that the side wall of the first through hole is away from the second through hole 525, and the side wall of the first through hole no longer applies force to the inoculation head 526, so that the inoculation head 526 is released from the limit, and the inoculation head 526 can be detached from the installation groove. When it is necessary to install the inoculation head 526, the pressing block 523 is pressed, and after the inoculation head 526 is inserted into the first through hole and the second through hole 525, the pressing block 523 is released, and the pressing block 523 can automatically clamp the inoculation head 526, thereby realizing the rapid disassembly and replacement of the inoculation head 526, and improving the work efficiency of installation and disassembly compared to methods such as disassembly by screws. It is also simple to operate, avoiding the inoculation ring 52 from being improperly installed due to manual operation caused by some experimenters not understanding the mechanical structure, thereby affecting the experimental results.

Figure 1 As shown, the workbench 100 defines a first area 101 , a second area 102 and a third area 103 that are arranged side by side.

[0126] like Figure 1 As shown, the sample processing assembly 10 is located in the first area 101 and includes a sample loading device 11 and a sample transfer device 17. The sample loading device 11 is used to place a sample container containing a sample, and the sample transfer device 17 is used to transfer the sample container between the first area 101 and the second area 102. The streaking and smearing assembly 20 is located in the second area 102 and includes a culture dish loading device 21, a glass slide loading device 22, an inoculation device 50, and a streaking and smearing device 23. The inoculation device 50 and the streaking and smearing device 23 are used to streak culture dishes 40 and / or smear glass slides. The sample collection assembly 30 is located in the third area 103 and includes a culture dish collection device 31 and a glass slide collection device 32. The culture dish collection device 31 is used to receive streaked culture dishes 40, and the glass slide collection device 32 is used to receive smeared glass slides.

[0127] In the disclosed embodiment, the workbench 100 is defined as a first area 101, a second area 102, and a third area 103. The sample processing assembly 10, the streaking and smearing assembly 20, and the sample collection assembly 30 are located in each of these three areas. This functional division of the system components prevents contamination between the various areas and interference between operational processes during sample processing. Furthermore, the first area 101, the second area 102, and the third area are arranged side by side, making it easier for users to operate and observe the sample processing process without having to move back and forth, and preventing interference between the previous and next processes.

[0128] Optionally, the first area 101, the second area 102, and the third area 103 are arranged side by side along the length or width of the workbench 100. Alternatively, the first area 101, the second area 102, and the third area 103 are arranged side by side along the diagonal direction of the workbench 100. In actual application, the first area 101, the second area 102, and the third area 103 can be arranged according to the size and shape of the workbench 100, or according to the user's usage habits.

[0129] The system is functionally divided into a sample processing component 10, a streaking and smearing component 20, and a sample collection component 30. The sample processing component 10 is used to process samples. When the system begins operation, a sample container containing a sample is placed in the sample loading device 11. The sample container is then transferred directly or after a series of processing to the second area 102 via the sample transfer device 17, allowing the inoculation device 50 to extract the sample. After the sample container is transferred to the second area 102 by the sample transfer device 17, the inoculation device 50 is returned to the first area 101 for recycling. After the sample transfer device 17 transfers the sample container to the second area 102, the inoculation device 50 extracts the sample from the sample container. Depending on the sample processing requirements, the inoculation device 50 selects a culture dish 40 for loading onto the culture dish loading device 21 or a glass slide for loading onto the glass slide 22. After the culture dish 40 or glass slide is placed in the streaking and smearing device 23, the inoculation device 50 streaks the extracted sample onto the culture dish 40 or smears the glass slide. The culture dish 40 after marking or the slide glass after smearing is transferred to the third area 103, and the sample collecting component 30 in the third area 103 collects the culture dish 40 after marking or the slide glass after smearing for the next step of processing.

[0133] In the disclosed embodiment, the streaking and smearing device 23 includes a tray 231, which can carry both culture dishes 40 and glass slides. In this way, the culture dishes 40 or glass slides can be placed in the tray 23 according to processing requirements. The tray 23 is then used in conjunction with the inoculation device 50 for streaking or smearing. In this way, both the glass slides and culture dishes 40 can cooperate with the inoculation device 50 to improve the versatility and ease of use of the system.

[0134] Optionally, the culture dish 40 includes a culture dish box body 42 and a culture dish cover 41, wherein the culture dish cover 41 is disposed on top of the culture dish box body 42. The cross section of the culture dish 40 is circular.

[0139] Optionally, the cover opening device is located on a side of the tray 231 facing the third area 103 .

[0140] Optional, such as Figure 5 As shown, the slide loading device 22 includes a sample discharging device 221 and a first push rod 222. The sample discharging device 221 can be raised and lowered on the workbench 100. The sample discharging device 221 is constructed with a first storage compartment arranged side by side in a vertical direction, and the first storage compartment is used to place the slide; the first push rod 222 is arranged on one side of the sample discharging device 221, and is used to push the slide in the first storage compartment out of the first storage compartment; wherein, the workbench 100 is constructed with a slide, and the streaking and smearing device 23 is slidably arranged on the slide, and the streaking and smearing device 23 can move along the slide to the other side of the sample discharging device 221 to carry the slide pushed out from the first storage compartment.

Glass slides are placed in the first storage compartment, and the glass slides to be smeared are all stored in the sample discharging device 221. A first push rod 222 is provided on the side of the first storage compartment facing away from the streaking and smearing device 23, so that the first push rod 222 can push the glass slides in the first storage compartment out of the first storage compartment to facilitate the transfer of the glass slides to the tray 231 of the streaking and smearing device 23. The streaking and smearing device 23 can move along a slide to the other side of the sample discharging device 221 and abut (fit or approach) the sample discharging device 221. In this way, the first push rod 222 pushes the glass slides to be smeared from one side of the sample discharging device 221 onto the tray 231. The streaking and smearing device 23 then returns along the slide to the preset inoculation position (referring to the position where the tray can cooperate with the inoculation loop for streaking or smearing) to facilitate smearing in cooperation with the inoculation device 50. In addition, the sample discharging device 221 can be raised and lowered on the workbench 100, so that after the slide corresponding to the first push rod 222 is pushed out, the height of the sample discharging device 221 can be adjusted so that the first push rod 222 corresponds to the first storage compartment with the slide.

[0142] Optionally, the first push rod 222 is drivingly connected to a first push rod 222 driving device, and the first push rod 222 driving device can drive the first push rod 222 to extend or retract.

[0143] Optionally, the slide loading device 22 further includes a first lifting mechanism, which is provided at the bottom of the sample discharging device 221 and is used to achieve the ascent and descent of the sample discharging device 221 .

[0144] For example, the first lifting mechanism may be a screw-nut structure or an electric push rod structure.

[0145] Alternatively, as Figure 1 and Figure 2 As shown, the slide loading device 22 is located in front of the inoculation device 50, making it easy for users to load slides onto the slide loading device 22 from the front of the workbench 100. A slideway extends in the front-to-back direction, from the inoculation preset position to one side of the loading device, to facilitate movement of the streaking and smearing device 23 between the inoculation preset position and the slide loading device 22.

[0146] Alternatively, as Figure 4As shown, the culture dish loading device 21 includes an operating platform 211, a storage bin 212 and a clamping jaw assembly. The operating platform 211 is rotatably arranged above the workbench 100. The storage bin 212 is arranged above the operating platform 211 and extends in the vertical direction for placing the culture dish 40. The lifting mechanism (hereinafter referred to as the second lifting mechanism 213 for the sake of convenience of description) is arranged at the bottom of the storage bin 212 and can contact the culture dish 40 in the storage bin 212 for lifting the culture dish 40. The clamping jaw assembly is arranged on one side of the operating platform 211. The clamping jaw assembly includes a clamping jaw 214 and a lifting and rotating mechanism 215. The clamping jaw 214 is located above the storage bin 212. The clamping jaw assembly is used to clamp the culture dish 40 and drive the culture dish 40 to move.

[0147] In the embodiment of the present disclosure, the culture dish loading device 21 is used to provide the culture dish 40 to be scribed to the streaking smear device 23, the storage bin 212 is used to place the culture dish 40, the second lifting mechanism 213 is located at the bottom of the culture dish 40, and can thereby drive the culture dish 40 to rise and fall to adjust the height of the culture dish 40, the clamping jaw 214 is located above the storage bin 212, and the clamping jaw 214 of the clamping jaw assembly is used to clamp the culture dish 40 in the storage bin 212 and drive the culture dish 40 to move to achieve the transfer of the culture dish 40. The lifting and rotating mechanism 215 is connected to the clamping jaw 214, and the clamping jaw 214 can be lifted and rotated relative to the operating platform 211 through the lifting and rotating mechanism 215 to achieve the grasping, transfer and placement of the culture dish 40. In addition, the culture dish loading device 21 of the embodiment of the present disclosure solves the manual operation in the microbiological inspection process, realizes the functions of automatic culture dish 40 selection, storage and clamping, avoids manual selection errors, and improves the efficiency of microbiological inspection work.

[0148] Optionally, a plurality of culture dishes 40 can be placed in a storage bin 212, and the plurality of culture dishes 40 are stacked vertically in the storage bin 212. In this way, when the culture dishes 40 on the upper layer of the storage bin 212 are grabbed, the second lifting mechanism 213 can lift the remaining culture dishes 40 from the bottom to facilitate the upper gripper 214 to grab the culture dishes 40. After the culture dishes 40 in the corresponding storage bin 212 are grabbed, the second lifting mechanism 213 can drive the remaining culture dishes 40 to descend to prevent the culture dishes 40 from falling and to avoid affecting the rotation of the operating platform.

[0149] Optionally, the second lifting mechanism 213 can pass through the workbench 100 and the operating platform 211. When the second lifting mechanism 213 rises into the storage bin 212, the second lifting mechanism 213 and the operating platform 211 are limited to restrict the rotation of the operating platform 211; when the second lifting mechanism 213 descends to the bottom of the operating platform 24, the second lifting mechanism 213 and the operating platform 24 are released from the limit, and the operating platform 24 can rotate relative to the workbench 100.

[0150] In the embodiment of the present disclosure, after the culture dish 40 in the corresponding storage bin 212 is grabbed, if it is necessary to grab the culture dish 40 in other storage bins 212, the controller controls the second lifting mechanism 213 to first drive the culture dish 40 in the storage bin 212 that grabs the culture dish 40 to descend, and the second lifting mechanism 213 descends to the bottom of the operating platform 211, releases the limit, and then controls the operating platform 211 to rotate so that the next target storage bin 212 rotates to the position corresponding to the clamp 214. At this time, the second lifting mechanism 213 is controlled to rise to lift the culture dish 40 in the target storage bin 212, and the second lifting mechanism 213 can be limited with the operating platform 211 to prevent the operating platform 211 from rotating when the clamp 214 is working.

[0151] Optionally, there are multiple storage bins 212 , and the multiple storage bins 212 are sequentially spaced apart along the circumference of the operating platform 211 .

[0152] In the disclosed embodiment, the operating platform 211 is provided with multiple storage bins 212, which can increase the storage capacity of culture dishes 40 and also improve the stability of the operating platform 211. Optionally, the multiple storage bins 212 can be of the same or different sizes and shapes. Optionally, the multiple storage bins can be loaded with the same type of culture dishes 40 or different types of culture dishes 40. In actual use, the type of culture dishes 40 in each storage bin 212 can be customized according to usage requirements.

[0153] Optionally, multiple storage bins 212 are arranged in a ring shape along the circumference of the operating platform 211, which can further improve the setting balance and stability of the operating platform 211.

[0154] Optionally, the culture dish loading device 21 further includes a position sensor 216 for detecting the position of the culture dish 40. The position sensor 216 is electrically connected to the gripper assembly and the second lifting mechanism 213. When the second lifting mechanism 213 raises the culture dish 40 to a predetermined position, the gripper assembly grips the culture dish 40 at the predetermined position. If there is no culture dish 40 at the predetermined position, the position sensor 216 transmits a signal to the second lifting mechanism 213, causing it to raise the culture dish 40.

[0155] In the disclosed embodiment, the position sensor 216 can sense the position of the culture dish 40 within the storage bin 212. When there is no culture dish 40 at the preset position, the second lifting mechanism 213 can lift the culture dish 40. When the culture dish 40 moves to the preset position, the gripper assembly can grip the culture dish 40, improving the convenience of gripping the culture dish 40. The position sensor 216 can automatically lift and lower the culture dish 40, improving the efficiency of automatic gripping of the culture dish 40, avoiding manual selection errors, and improving the efficiency of microbiological testing. Optionally, the position sensor 216 corresponds to the upper portion of the storage bin 212 to facilitate the gripper 214 to grip the culture dish 40.

[0156] Optionally, the culture dish loading device 21 further includes a support column, which is located inside the multiple storage bins 212 , and a position sensor 216 is provided on the support column. Thus, one position sensor 216 can detect the positions of the culture dishes 40 in multiple storage bins 212 .

[0157] Optionally, the operating platform 211 is rotatably mounted on the workbench 100 , and the operating platform 211 can rotate around its axis, so that the multiple storage bins 212 on the operating platform 211 can also rotate around the axis of the operating platform 211 .

[0158] In the disclosed embodiment, since the gripper assembly is positioned on one side of the operating platform 211 and there are multiple storage bins 212, the operating platform 211 can rotate, allowing each storage bin 212 to rotate to a position corresponding to the gripper assembly, thereby facilitating the gripper assembly's grasping of culture dishes 40 from different storage bins 212. Furthermore, the operating platform 211 rotates about its own axis, reducing the space occupied by the rotating operating platform 211. This also eliminates the need for the gripper assembly to rotate about the operating platform 211, reducing the space occupied by the culture dish loading device 21 and improving the system's structural compactness.

[0159] Optionally, the culture dish loading device 21 and the glass slide loading device 22 are arranged side by side, which makes it convenient for the user to replenish culture dishes 40 to the culture dish loading device 21 and to replenish glass slides to the glass slide loading device 22. Specifically, the culture dish loading device 21 and the glass slide loading device 22 are located on the front side of the inoculation device 50.

[0160] Optionally, the culture dish loading device 21 and the glass slide loading device 22 are arranged in a direction from the first area 101 to the second area 102, and the distance between the streaking and smearing device 23 and the glass slide loading device 22 is smaller than the distance between the streaking and smearing device 23 and the culture dish loading device 21. Optionally, the streaking and smearing device 23 is located behind the glass slide loading device 22, and the culture dish loading device 21 is located to the left of the glass slide loading device 22. Here, because the streaking and smearing device 23 needs to move through a slide and cooperate with the glass slide loading device 22, while the culture dish loading device 21 can be transferred by the clamp 214, the distance between the streaking and smearing device 23 and the glass slide loading device 22 is smaller, which can save the length of the slide and avoid interference between different processes. This makes the layout of the various devices of the streaking and smearing assembly 20 in the second area 102 more reasonable, conforms to the biological detection experiment process, and improves sample processing efficiency.

[0161] Optionally, the clamping jaw assembly is located between the operating platform 211 and the slide loading device 22 to reduce the distance that the clamping jaw 214 moves to the streaking and smearing device 23 .

In the disclosed embodiment, the sample scanning device 15 can recognize the label of the sample container to facilitate identification and recording of the contents of the sample.

[0163] Optionally, the sample transfer device 17 is movably located between the first area 101 and the second area 102 , the sample code scanning device is located on one side of the sample loading device 11 , and the sample container is removed from the sample loading device 11 and scanned by the sample code scanning device 15 before operation.

[0164] Optionally, the sample transfer device 17 is a sample extraction station 601 , that is, the sample extraction station is located between the first area 101 and the second area 102 .

[0165] Alternatively, as Figures 1 to 3 As shown, the sample processing assembly further includes a liquid adding and grabbing device 13, which includes a liquid adding device and a sample clamp connected thereto. The sample clamp is used to transfer the sample container and / or open and close the cover of the sample container, and the liquid adding device is used to add liquid into the sample container.

[0166] In the embodiment of the present disclosure, the liquid adding gripping device 13 integrates the sample clamp and the liquid adding device into one. The sample clamp can transfer the sample container in the first area 101 and can open and close the cover of the sample container. For example, the sample clamp can clamp the sample container in the sample loading device 11 and place it on the sample scanning device for scanning. The sample container can also be placed in the sample transfer device 17 for transfer. At the same time, the sample clamp can open or close the cover of the sample container to facilitate the extraction of the sample in the sample container, or to add other liquids to the sample container. In addition, the liquid adding gripping device 13 also includes a liquid adding device. When the sample is a sputum specimen, digestive fluid needs to be added to the sample to convert the viscous sputum into a liquid state for subsequent operations. Therefore, the liquid adding extraction device of the embodiment of the present disclosure integrates the liquid adding device on the sample clamp to achieve unified control, thereby improving the sample processing efficiency.

[0167] Optionally, the sample clamp further includes a guide rail assembly, a robotic arm 134, and a robotic arm gripper 135.

The robotic arm gripper 135 is mounted at the lower end of the robotic arm 134 and is used to grip the sample container and / or open and close the lid of the sample tube. In the disclosed embodiment, the guide rail assembly includes the X-axis guide rail 136, the Y-axis guide rail 137, and the Z-axis guide rail 138. This enables the robotic arm gripper 135 to move in three directions, thereby increasing the range of motion of the sample clamp and improving gripping flexibility. The robotic arm 134 is mounted on the Z-axis guide rail 138, and the robotic arm gripper 135 is mounted at the lower end of the robotic arm 134. The robotic arm 134 facilitates the robotic arm gripper 135 to grasp the sample container, and the robotic arm gripper 135 is capable of gripping and / or opening and closing the lid of the sample container.

[0168] Optionally, the X-axis guide rail 136 is movably disposed on the Y-axis guide rail 137, the Z-axis guide rail 138 is movably disposed on the X-axis guide rail 136, and the robotic arm 134 is movably disposed on the Z-axis guide rail 138. Specifically, the robotic arm 134 is slidably connected to the Z-axis guide rail 138, and the robotic arm 134 can move in a first direction relative to the Z-axis guide rail 138. The Z-axis guide rail 138 drives the robotic arm 134 to move in a second direction relative to the X-axis guide rail 136. The Z-axis guide rail 138 and the X-axis guide rail 136 drive the robotic arm 134 to move in a third direction relative to the Y-axis guide rail 137. The first direction is the vertical direction, the second direction is the left-right direction, and the third direction is the front-to-back direction. It can be understood that the Z-axis guide rail 138 extends in the vertical direction, the X-axis guide rail 136 extends in the left-right direction, and the Y-axis extends in the front-to-back direction.

[0169] Optionally, the robotic arm clamp 135 includes a first clamp and a second clamp, and the first clamp and the second clamp can move toward or away from each other. When the first clamp and the second clamp move toward each other, the robotic arm clamp 135 can clamp the sample container. When the first clamp and the second clamp move away from each other, the robotic arm clamp 135 can release the sample container.

[0170] Optionally, the robotic arm clamp 135 is rotatably arranged at the lower end of the robotic arm 134, so that the robotic arm clamp 135 can rotate relative to the robotic arm 134. After the robotic arm clamp 135 clamps the cover of the sample container, the robotic arm clamp 135 can rotate counterclockwise or clockwise to open or close the cover of the sample container.

[0171] Optionally, the liquid adding device is provided on one side of the robotic arm 134, and the liquid adding device includes a connected liquid storage bottle 132, a liquid adding pump 133 and a liquid adding needle 131. The liquid adding needle 131 is connected to the robotic arm 134, and the liquid adding needle 131 can move with the robotic arm 134 to add liquid to the sample container.

[0172] In the disclosed embodiment, the liquid storage bottle 132 is used to place the digestive fluid, and the liquid adding needle 131 is used to discharge the liquid so as to add the digestive fluid to the sample container. The liquid adding pump 133 can provide a driving force for the flow of the digestive fluid in the liquid storage bottle 132 to ensure that the digestive fluid can flow out of the liquid adding needle 131. After the robotic arm clamp 135 opens the cover of the sample container, the robotic arm clamp 135 clamps the cover of the sample container, and the robotic arm 134 drives the liquid adding needle 131 to move toward the left or right side so that the liquid adding needle 131 corresponds to the opening of the sample container, and the liquid adding pump 133 draws any amount of digestive fluid from the liquid storage bottle 132 and adds it to the sample container. Then the robotic arm 134 drives the liquid adding needle 131 to move in the opposite direction, and the robotic arm clamp 135 aligns the sample container and rotates the cover of the sample container to cover the sample container.

[0173] Optionally, the liquid storage bottle 132 is connected to the robotic arm 134 and / or the Z-axis guide rail 138 to prevent the pipeline of the liquid storage bottle 132 from affecting the movement of the robotic arm 134.

[0174] Optionally, the liquid adding pump 133 is connected to the robotic arm 134 and / or the Z-axis guide rail 138 to prevent the pipeline between the liquid storage bottle 132 and the liquid adding pump 133 from affecting the movement of the robotic arm 134 .

[0175] Optionally, the adding needle 131 is located on one side of the robotic arm clamp 135, and the lower end of the adding needle 131 is at the same or similar height as the lower end of the robotic arm clamp 135. This makes it convenient for the adding needle 131 to move to the top of the sample container after the robotic arm clamp 135 opens the cover of the sample container to add digestive fluid into the sample container.

[0176] Optionally, the sample clamp also includes a pressure sensor, which is provided on the robotic arm clamp 135. When the robotic arm clamp 135 clamps the sample container, the pressure sensor can feedback pressure to determine whether the robotic arm clamp 135 clamps the sample container tightly, thereby avoiding failure to clamp or clamping too tightly.

[0177] Optionally, when the sample container is opened or closed, the robotic arm gripper 135 rotates a preset number of turns, which can be set according to the rotation memory to ensure the stability of the opening and closing of the sample container cover, and avoid the problem of the cover not turning when opening or the cover closing with excessive pressure.

The oscillating device 14 is configured with an oscillating tank. The sample holder can transfer the sample container from the sample loading device 11 into the oscillating tank. The oscillating device 14 is used to oscillate the sample container to improve the mixing uniformity of the solution in the sample container. In addition, the oscillating tank can also fix the sample container, making it easier for the sample holder to open and close the sample container cover and for the liquid adding device to add liquid.

[0179] Optionally, the oscillation device 14 is located below the robotic arm clamp 135 of the sample clamp, the depth of the oscillation groove is less than the height of the sample container, and the difference between the depth of the oscillation groove and the height of the sample container is the same as or close to the height of the cover of the sample container. In this way, when the sample container is placed in the oscillation groove, the robotic arm clamp 135 can clamp the cover of the sample container to facilitate opening or closing the cover of the sample container. At the same time, after the sample container is opened, the liquid adding device can also move to the top of the sample container with the guide rail assembly or the robotic arm 134. Under the driving action of the liquid adding pump 133, the liquid adding needle 131 adds the digestive fluid in the liquid storage bottle 132 into the opened sample container.

[0180] Alternatively, as Figure 3 As shown, the sample clamp also includes a fixing part 139, which is provided on the robotic arm 134, and the fixing part 139 is located on one side of the robotic arm clamp 135. After the sample container is filled with liquid, when the sample container needs to be shaken, the robotic arm 134 drives the fixing part 139 to move to the top of the sample container, and the fixing part 139 can abut against the top of the sample container. In this way, when the sample container is shaken, the fixing part 139 can prevent the sample container from shifting or jumping out of the shaking tank.

[0181] Optionally, the fixing member 139 is located at the rear side of the manipulator gripper 135. Optionally, the cross-sectional area of ​​the fixing member 139 is larger than the opening area of ​​the sample container to prevent the sample in the sample container from splashing out. For example, the fixing member 139 can be elongated or circular.

[0182] Optionally, the sample processing assembly further includes a heating device 142 . The liquid adding device is disposed on one side of the oscillating device 14 and is used to heat the sample in the sample container.

[0183] In the disclosed embodiment, the heating device 142 is capable of heating the solution within the sample container to incubate the sample in the sample container. The heating device 142 is located on one side of the oscillating device 14. After the sample container is oscillated by the oscillating device 14, it can be transferred to the heating device 142 via the sample holder for incubation. In actual use, the sample container can be selectively placed on the heating device 142 and / or the oscillating device 14, depending on the type of sample.

[0184] Optionally, the sample processing assembly further includes a sample collecting device 16 , which is located on a side of the sample transferring device 17 facing the first area 101 and is used to collect the sample container after the sample is extracted.

[0185] Optionally, the sample loading device 11, the sample scanning device 15, and the heating device 142 are sequentially arranged along the length of the first region 101, the liquid adding and grabbing device 13 is located on the side of the sample loading device 11, the sample scanning device 15, and the heating device 142 facing away from the second region 102, and the sample clamp is located above the sample loading device 11, the sample scanning device 15, the oscillating device 14, and the heating device 142 to facilitate the transfer of sample containers between the sample loading device 11, the sample scanning device 15, the oscillating device 14, and the heating device 142. This fully utilizes the space in the first region 101 and rationally arranges the positions of each device, which not only meets the requirements of biological detection experiments, but also saves space, reduces the movement path of the sample clamp, and improves sample processing efficiency.

[0186] Optionally, the oscillating device 14 and the heating device 142 are arranged side by side in the left-right direction, with the sample loading device 11 located in front of the oscillating device 14 and the heating device 142, and the sample scanning device and the sample collection device located between the sample loading device 11, the oscillating device 14, and the heating device 142. The sample scanning device is located in front of the sample collection device. The sample transfer device 17 is located to the right of the sample loading device 11 and the sample collection device 16. This can reduce the movement path of the sample holder when the sample transfer device 17 cooperates with other devices. The Y-axis guide rail 137 of the sample clamp is located on the left side of the sample loading device 11 and the oscillating device 14, and the length of the Y-axis guide rail 137 is the same as or similar to the length of the first area 101. The X-axis guide rail 136 is located on the rear side of the oscillating device 14 and the heating device 142, and the width of the X-axis guide rail 136 is the same as or similar to the width of the first area 101. This can increase the range of motion of the robotic arm 134 and ensure that the robotic arm 134 clamp can be clamped to any position in the first area 101 to facilitate the transfer of sample containers without the need to set up multiple sample clamps. For example, the sample container of the sample loading device 11 can be clamped to the sample scanning device for scanning, or the sample container can be clamped to the oscillating device 14 or the heating device 142, or the sample container can be clamped to the sample transfer device 17 for transfer, or the extracted sample container can be transferred to the sample collection device.

The transfer platform is used to place the sample container. The transfer platform is slidably mounted on the second slideway. The drive device can drive the transfer platform along the second slideway, which extends from the first area 101 to the second area 102. In this way, after the sample fixture places the processed sample on the transfer platform, the transfer platform can move along the second slideway to the sample extraction station 601 in the second area 102, so that the inoculation device 50 can extract the solution from the sample container.

[0188] Alternatively, as Figure 1 As shown, the sample processing assembly also includes a receiving device 12, which is located on the side of the first area near the second area. The receiving device includes a receiving cover and a driving mechanism, and the driving mechanism can drive the receiving cover to move horizontally. When the liquid adding and grabbing device places the sample container in the sample transfer device 17, the sample clamp opens the cover of the sample container. The cover of the sample container is always clamped by the liquid adding device. After the cover is opened, the sample container is transferred to the second area with the sample transfer device. The receiving cover of the receiving device moves to the bottom of the sample clamp and is located below the cover of the sample container to receive liquid dripping from the cover of the sample container to prevent the liquid from dripping onto the workbench.

[0189] Alternatively, as Figure 1 and Figure 2 As shown, the sample collecting component 30 includes a gripping device 35, a printing device 33, a coding device 34, a glass slide collecting device and a culture dish sample collecting device 31.

[0190] In the disclosed embodiment, the gripping device 35 can grasp and transfer the scribed culture dish 40 or the smeared glass slide, thereby realizing storage of the culture dish 40 or the glass slide. The printing device 33 is used to label the scribed culture dish 40, and the coding device 34 is used to code the smeared glass slide, thereby realizing record keeping and summary of the culture dish 40 and the glass slide.

[0191] Alternatively, as Figure 6 As shown, the slide collecting device 32 includes a movable platform 322, a sample collecting device 321 and a second push rod 323. The movable platform 322 is movably arranged on the workbench 100, and the movable platform 322 is used to place the slides after smearing; the sample collecting device 321 can be raised and lowered on the workbench 100, and the movable platform 322 can move to one side of the sample collecting device 321. The sample discharging device 221 is constructed with a plurality of second storage compartments 3211 arranged in a vertical direction, and the second storage compartments 3211 are used to place the slides after smearing; the second push rod 323 is located on one side of the sample collecting device 321, and is used to push the slides on the movable platform 322 into the second storage compartments 3211.

[0192] In the embodiment of the present disclosure, after the glass slides are smeared on the tray 231, the gripping device 35 transfers the smeared glass slides to the movable platform 322. The movable platform 322 can move relative to the workbench 100, and the movable platform 322 can move to the side of the sample receiving device 321 and connect with the sample receiving device 321. The second push rod 323 can push the glass slides on the movable platform 322 into the second storage compartment 3211. The sample receiving device 321 can also be raised and lowered relative to the workbench 100. When the storage compartment corresponding to the second push rod 323 is loaded with a glass slide, the sample receiving device 321 can be raised or lowered so that the empty second storage compartment 3211 is aligned with the second push rod 323 to facilitate the placement of additional glass slides.

[0193] Alternatively, as Figure 8As shown, the culture dish sample collecting device 31 includes a sample collecting platform 311 , a sample collecting chamber 312 , a lifting mechanism 313 , a slide rail 314 and a turning mechanism 315 . The sample receiving platform 311 is movably arranged on the workbench 100, and the sample receiving bin 312 is arranged on the sample receiving platform 311 and extends in the vertical direction. The sample receiving bin 312 defines a plurality of storage spaces, and the storage space is used to place the labeled culture dishes 40; the lifting mechanism 313 is arranged at the bottom of the storage space, and the lifting mechanism 313 is used to lift the culture dishes 40 in the storage space; one end of the slide rail 314 is connected to the sample receiving bin 312, and the other end of the slide rail 314 corresponds to the printing device 33. The grasping device 35 can grasp the culture dish 40 on the slide rail 314 so that the culture dish 40 moves along the slide rail 314 into the sample receiving bin 312; the flipping mechanism 315 is arranged on the slide rail 314, and is used to flip the culture dish 40 on the slide rail 314 so that the culture dish 40 is stored upside down in the storage space.

[0194] In the disclosed embodiment, after the petri dish 40 has been marked by the gripping device 35, it is transferred to the printing device 33 for labeling. The labeled petri dish 40 then moves via the slide rail 314 to the petri dish sample receiving device 31 for sample collection. Specifically, the labeled petri dish 40 moves toward the sample receiving platform 311. The slide rail 314 is provided with a flipping mechanism 315. The flipping mechanism 315 can flip the petri dish 40 so that the petri dish 40 can be stored upside down in the sample receiving chamber 312. This facilitates the growth of the strains in the petri dish 40 and maintains the tightness of the petri dish 40.

[0195] Optionally, one end of the slide rail 314 is connected to the bottom of the storage space, and the flipped culture dish 40 moves to the bottom of the corresponding storage space along the slide rail 314, and the lifting mechanism 313 drives the culture dish 40 to rise to a preset position. The preset position refers to the position where the culture dish 40 contacts the lower wall surface of the culture dish 40 stored in the storage space. The culture dish sample collecting device 31 also includes a stop mechanism 316, which is movably arranged at the bottom of the storage space. The stop mechanism 316 can move between a fifth position and a sixth position. When the stop mechanism 316 is in the fifth position, the stop mechanism 316 does not block the storage space, and the lifting mechanism 313 can drive the culture dish 40 to rise; when the lifting mechanism 313 drives the culture dish 40 to rise to the preset position, the stop mechanism 316 moves to the sixth position, and the stop mechanism 316 blocks the bottom opening of the storage space and abuts against the lower wall of the lowest culture dish 40 to prevent the culture dish 40 from falling and reserve enough space for the next culture dish 40. At the same time, the stop mechanism 316 will not block the lifting mechanism 313. When the stop mechanism 316 abuts against the bottom of the culture dish 40, the lifting mechanism 313 descends.

[0196] Optionally, the stop structure includes a rotation shaft and a stop plate, the stop plate being rotatably connected to the operating platform 211 via the rotation shaft. When the stop mechanism 316 is in the fifth position, the stop plate extends upward or downward to facilitate the ascent of the culture dish 40. When the stop mechanism 316 is in the sixth position, the stop plate extends toward the bottom opening of the storage space, thereby reducing the bottom opening area of ​​the storage space and facilitating contact with the culture dish 40.

[0197] Alternatively, as Figure 9 As shown, the printing device 33 includes a printer 331, a labeling platform 333 and a labeling mechanism 332. The labeling platform 333 is provided on one side of the printer 331 and is used to carry the culture dish 40 to be labeled; the labeling mechanism 332 is provided on one side of the printer 331 and is used to label the culture dish 40 on the labeling platform 333.

[0198] Among them, when the culture dish 40 is labeled, the gripping device 35 clamps the culture dish cover 41, and the culture dish box body 42 moves downward. The culture dish box body 42 moves downward a preset distance, increasing the exposed height of the side wall of the culture dish box body 42, so that the labeling mechanism 332 can label the side wall of the culture dish box body 42.

[0199] In the embodiment of the present disclosure, the inoculated culture dish 40 is transferred to the printing platform by the gripping device 35. When the culture dish 40 moves to the top of the printing platform, the gripping device 35 clamps the culture dish cover 41, so that the culture dish box 42 moves downward a preset distance under the action of gravity. At this time, the exposed area of ​​the side wall of the culture dish box 42 increases, which makes it easier for the labeling mechanism 332 to stick the label on the side wall of the culture dish cover 41. This can not only realize the automatic labeling of the culture dish 40, but also facilitate the later observation of the culture dish 40.

[0200] Optionally, when the culture dish box body 42 moves downward a preset distance, the culture dish cover 41 is connected to the culture dish box body 42, so that the culture dish cover 41 is in a closed state. In other words, when the culture dish 40 is labeled, the culture dish cover 41 and the culture dish box body 42 are not completely separated, which can prevent the culture dish 40 from being contaminated during the labeling process.

[0201] Optionally, the grasping device 35 includes a mobile device, a grasping arm 134, a first grasping jaw 214, and a second grasping jaw 214.

The first grasping jaw 214 and the second grasping jaw 214 are located at the lower end of the grasping arm 134. The first grasping jaw 214 is located outside the second grasping jaw 214, and the length of the first grasping jaw 214 is greater than the length of the second grasping jaw 214. When the grasping device 35 grasps the culture dish 40, the second grasping jaw 214 is adsorbed on the top of the culture dish cover 41, and the first grasping jaw 214 is clamped on the circumferential outer wall of the culture dish box 42 to drive the culture dish 40 to move. When the grabbing device 35 drives the culture dish 40 to move above the labeling platform 333, the first grabbing jaw 214 is released and the second grabbing jaw 214 adsorbs the culture dish cover 41, so that the culture dish box 42 can move downward a preset distance under the action of gravity, thereby facilitating labeling.

[0202] Alternatively, as Figure 1 and Figure 6 As shown, the slide collecting device 32 includes a movable platform 322, a sample collecting device 321 and a second push rod 323. The movable platform 322 is movably arranged on the workbench 100 and is used to place the slides after smearing; the sample collecting device 321 can be raised and lowered on the workbench 100, and the movable platform 322 can move to one side of the sample collecting device 321. The sample collecting device 321 is constructed with a plurality of second storage compartments 3211 arranged in a vertical direction. The second storage compartments 3211 are used to place the slides after smearing; the second push rod 323 is located on one side of the sample collecting device 321 and is used to push the slides on the movable platform 322 into the second storage compartments 3211.

[0203] In the disclosed embodiment, the smeared glass slide is transferred from the tray 231 to the mobile platform 322 via the gripping device 35. The mobile platform 322 drives the smeared glass slide to one side of the sample receiving device 321. When the mobile platform 322 is in contact with or close to the sample receiving platform 311, the second push rod 323 can push the glass slide on the mobile platform 322 into the second storage compartment 3211. When a glass slide is placed in the second storage compartment 3211 corresponding to the second push rod 323, the sample receiving device 321 raises and lowers the position of the second storage compartment 3211 so that the empty second storage compartment 3211 is aligned with the second push rod 323 and the mobile platform 322, thereby accommodating the smeared glass slide.

[0204] Optionally, the mobile platform 322 is provided with a heating element, which can increase the temperature of the mobile platform 322. In this way, after the smeared slide is placed on the mobile platform 322, the heating element increases the temperature of the mobile platform 322, which can increase the air drying speed of the sample on the slide.

[0205] Optionally, the movable platform 322 is slidably connected to the workbench 100, and the work platform is provided with a movable slide rail 314. The movable platform 322 is slidably connected to the movable slide rail 314, and the movable slide rail 314 extends in the front-to-back direction. One end of the movable slide rail 314 corresponds to the sample collecting device 321, so that the slide after smearing can move to be close to the sample collecting device 321.

[0206] Optionally, the movable rail 314 is located on the side of the streaking and smearing device 23 facing the third area 103, and the movable rail 314 is located between the labeling device and the streaking and smearing device 23, and the sample receiving device 321 is located in front of the movable rail 314. This can shorten the distance between the glass slide after the smear is grabbed by the grabbing device 35 and the movable platform 322. Since the glass slide does not need to be labeled, the sample receiving process is relatively simple. The placement of the movable rail 314 on the side of the third area 103 near the second area 102 makes the system structure more compact. In addition, the location of the sample receiving device 321 in the front also makes it easier for the user to replace the sample receiving device 321.
