Description

TECHNICAL FIELD

[0001] The utility model belongs to the automation acquisition technical field, more specifically, relate to a system for the glass bottle inside cultivating plant seedling is acquired. BACKGROUND

[0002] Put plant seedling into glass bottle and cultivate by culture medium, then plant, it is a common practice in plant tissue culture or seedling technique. By placing the glass bottle in a thermostat or culture room, the growth rate of the plant seedling is controlled by adjusting the temperature; by adjusting the light intensity and light time, the photosynthesis and growth rhythm of the plant seedling can be affected; the growth conditions are accurately controlled to optimize the growth of the plant seedling; at the same time, through plant tissue culture technology, rapid propagation can be promoted, and the propagation coefficient can be improved; greatly shorten the propagation cycle, especially important for rare or difficult to propagate tree species. In short, the cultivation of plant seedlings in glass bottles can optimize plant seedling growth, rapid propagation, and facilitate observation and management, and has been widely used on a large scale.

[0003] Therefore, in order to protect the health of plant seedlings and improve the survival rate of transplanting, the detection of microorganisms in the glass bottle is very important; through regular detection, it can be found whether there is fungal and bacterial contamination in the culture medium or culture environment, so as to take corresponding measures to reduce the risk of plant seedling disease in the culture process and cultivate more robust plants. But the existing detection of glass bottle cannot realize batch operation, and needs to detect each glass bottle separately, which is time-consuming, low in efficiency and high in cost, and the detection accuracy also has a lot of room for improvement.

[0004] The above problems have also been improved, such as Chinese patent publication No. CN116026861A, published on April 28, 2023, which discloses a glass bottle detection method and system, including the following steps: the glass bottle passing through the conveying belt is photographed to obtain the glass bottle detection image; the detection image is positioned to obtain the area where the glass bottle is located in the detection image, and the detection frame is rotated to the area where the glass bottle is located; the image in the detection frame is analyzed to determine whether the glass bottle in the detection frame has defects, if there are defects, the glass is marked as defective product, if there are no defects, the size of the glass bottle is detected to determine whether it meets the size threshold, if it does not meet the size requirement, it is marked as defective product. Although this patent reduces the cost of manual detection, but if it is directly applied to the detection of microorganisms in the glass bottle, there will be the problems of incomplete detection and poor accuracy.

[0005] For example, Chinese Patent Publication No. CN110066724A, published on July 30, 2019, discloses a real-time monitoring device and detection method for microbial culture. The monitoring device includes a culture box, a storage device, an imaging device, an operating device, a complete sample storage device, and a control system arranged in the culture box. The detection method continuously moves the culture dish in the storage device to the imaging device through the operating device. After the imaging device obtains the image information of the culture dish, it is compared and counted to form a detection result. The culture dish is moved back to the storage device after imaging. The disadvantage of this patent is that the distribution of microorganisms in the glass bottle may not be uniform, which may result in inaccurate detection results. Utility model content

DETAILED DESCRIPTION

[0034] The utility model will be further described below in combination with specific embodiments and drawings.

[0035] like Figure 1 As shown, an automated system for inspecting the interior of glass bottles containing plant seedlings includes a feeding area 1 and a collection area 2 connected in sequence, and a conveyor belt 3 running through the feeding area 1 and the collection area 2. Specifically, the collection area 2 includes a frame, and the conveyor belt is located below the frame. A top collection mechanism, a middle collection mechanism 21, and a bottom collection mechanism 22 are arranged in sequence on the frame along the conveyor belt's transport direction. The top collection mechanism is located at the end of the frame closest to the feeding area 1. That is, the glass bottles fed from the feeding area 1 are first collected from the top, then from the middle, and finally from the bottom.

[0036] The acquisition area 2 includes a top acquisition mechanism for acquiring images of the top of the glass bottle, a middle acquisition mechanism 21 for acquiring images of the body of the glass bottle, and a bottom acquisition mechanism 22 for acquiring images of the bottom of the glass bottle.

[0037] It should be noted that the detection system is equipped with three acquisition mechanisms, each capturing images of different parts of the glass bottle. This serves two purposes: firstly, it increases the comprehensiveness of the image capture for a single bottle, improving the accuracy of subsequent inspections; secondly, the three acquisition mechanisms are arranged on the same production line, sequentially capturing images of the bottle top, body, and bottom, saving costs and enabling batch image acquisition of glass bottles, thus improving acquisition efficiency and consequently, subsequent inspection efficiency. It is also important to note that capturing an image of the bottle top refers to capturing the image of the bottle cap, and capturing an image of the bottle bottom refers to capturing the image of the bottom of the bottle.

[0038] The central acquisition mechanism 21 includes a clamping and rotating component. This component clamps and fixes the glass bottle, allowing image acquisition of the bottle body while it is rotating. It's worth noting that since the central acquisition mechanism 21 acquires images of the bottle body, it can capture images of the entire bottle's circumference while the bottle is rotating, increasing the comprehensiveness of the acquisition. More importantly, the clamping and rotating component ensures that the glass bottle begins to rotate immediately after being fixed, preventing damage to the contents and features (culture medium and potential detection targets) from sudden acceleration. More specifically, the bottle rotation parameters are: a rotational speed of 10-15 RPM and a linear velocity at the bottle mouth of 0.03-0.05 m / s. Maintaining these parameters ensures clear, focused imaging while the bottle is rotating.

[0039] Of course, the control area is also included in the embodiment to achieve the purpose of automatic collection; the control area is connected with the feeding area 1 and the collection area 2 respectively to realize automatic feeding and collection of the glass bottles; wherein the control area includes an image detection module for detecting the images collected by the collection area 2, the image detection module is used for detecting whether there is fungus in the glass bottle collected by the top collection mechanism and the bottom collection mechanism 22; and for detecting whether there is fungus and whether there is bacteria in the glass bottle collected by the middle collection mechanism 21; the glass bottle is transparent, and the inside of the glass bottle includes plant seedlings and culture medium for cultivating the plant seedlings.

[0040] Specifically, the control area is capable of realizing automatic feeding and automatic collection process; the control area can be realized by program programming of the upper computer, which belongs to the prior art and does not involve the core of the present application, so the embodiment does not explain in detail how the control area realizes the control of feeding and collection.

[0041] The image detection module in the control area is specifically explained, because the inventor of the present application has found through continuous research and observation that fungus has visible characteristics such as hair, and the bottle cap is the only channel for the glass bottle to contact with the outside environment, and fungus spores can be transmitted through the air and invade when the bottle cap is opened, closed or not tightly sealed; the bottle bottom is easy to deposit culture medium residues, plant seedling debris or condensed water, forming a local high humidity and aerobic environment, which is suitable for the growth of fungus which is mostly aerobic bacteria; bacteria are variable and small, and most of the bacteria are anaerobic bacteria, so there is lack of culture medium and aerobic environment in the space of the bottle cap and the bottle body, and most bacteria are difficult to colonize in this place; bacteria tend to be evenly distributed in the culture medium which is rich in nutrients and isolated from oxygen; therefore, the possibility of bacteria distribution in the bottle bottom is much smaller than that in the bottle body; as for the bottle body, the bottle body contains plant seedlings and culture medium, which is the main place for the growth of microorganisms, and the possibility of distribution of bacteria and fungus in this place is large. Therefore, the image detection module only detects fungus on the bottle cap and the bottle bottom, and detects fungus and bacteria on the bottle body, which optimizes the allocation of resources, realizes fast positioning of external pollution sources through fungus detection on the bottle cap and the bottle bottom, and avoids high cost of comprehensive detection; comprehensive detection of the bottle body ensures the safety and health of the core culture area, balances the precision and resource consumption, and realizes efficient and comprehensive detection of microbial pollution in the glass bottle.

[0042] Specifically, the image detection module includes a first deep learning model for fungus detection on the bottle cap and the bottle bottom, and a second deep learning model for fungus detection and bacteria detection on the bottle body, and the first deep learning model and the second deep learning model can use existing target detection models or other neural network models, as long as they can realize the functions described in the present application.

[0043] Of course, the first deep learning model can be one of the ConvNeXt model, ResNet50 model, or YOLOv5s model; the second deep learning model includes a ConvNeXt model or ResNet50 model for fungal detection and a YOLOv5s detection model for bacterial detection. The YOLOv5s detection model includes a backbone network, a neck network, and a detection head; the backbone network adopts CSPDarknet, and SPPF modules are added to the ends of CSPDarknet; the neck network adopts PANet, and the detection head adopts three sub-detection heads of different sizes.

[0044] It should be noted that, considering the structural and distribution characteristics of bacteria: bacterial hyphae appear as tiny diffuse light spots (50-200 pixels in diameter) in the near-infrared band (700-1100nm), i.e., in industrial cameras. Their morphological characteristics are significantly similar to microcracks in industrial X-ray images and cellular lesions in medical microscopic images. The light spot intensity of bacterial hyphae is only 1.2-1.8 times that of the background, requiring the deep feature abstraction capability of CSPDarknet to separate effective signals. Moreover, hyphae can be linear (new hyphae), branched (mature hyphae), etc., and the multi-scale pooling of the SPPF module can cover morphological variations from 5×5 to 13×13 pixels. Furthermore, three sub-detection heads of different sizes correspond to large, medium, and small targets respectively, effectively solving the problem of scale differences caused by different growth stages of bacterial hyphae. The smallest sub-detection head is dedicated to the localization of targets smaller than 50 pixels. In summary, the YOLOv5s detection model can perform accurate and efficient detection based on the characteristics of bacteria, thus achieving a balance between accuracy and efficiency in bacterial detection. The entire detection method is time-efficient, highly accurate, and fast, and has the potential for large-scale application.

[0045] This system, by setting up three acquisition mechanisms within the acquisition area 2, captures images of different locations on the glass bottle, ensuring comprehensive internal inspection. This allows for multi-dimensional inspection on a single production line, improving accuracy while maximizing cost savings. Simultaneously, it performs fungal testing only on the cap and bottom, while testing the body for both fungi and bacteria. This optimized resource allocation allows for rapid localization of external contamination sources through cap and bottom fungal testing, avoiding the high costs of comprehensive testing. Comprehensive testing of the body ensures the safety and health of the core culture area, balancing accuracy and resource consumption, achieving efficient and comprehensive detection of microbial contamination within the glass bottle. The entire system achieves both automated operation, improving inspection efficiency, and comprehensive inspection of the glass bottle, enhancing accuracy.

[0046] In one specific embodiment, the structural composition of the central acquisition mechanism 21 is explained in detail as follows: Figure 2As shown, the middle collection mechanism 21 comprises a first imaging device 211 and a first separation cutoff device 212, which are respectively arranged on both sides of the conveying belt 3; one side of the first separation cutoff device 212 is provided with a first counting sensor, and when the first counting sensor counts to a first threshold value, the first separation cutoff device 212 is triggered to perform a separation cutoff action on the glass bottles on the conveying belt 3. Here, the first counting sensor is arranged in order to consider that when the middle collection mechanism 21 simultaneously detects multiple glass bottles, the same number of glass bottles can be operated each time to ensure the consistency and accuracy of the results; and in order to consider that when multiple glass bottles are simultaneously detected, the detection result can be traced back to which glass bottle or which glass bottles, so as to facilitate the quick finding of unqualified glass bottles; when the first counting sensor counts to the first threshold value, a signal is sent to the control area, and the control area receives the signal and then drives the first separation cutoff device 212 to act, wherein the first separation cutoff device 212 comprises a telescopic rod arranged on one side of the conveying belt, one end of the telescopic rod is connected to a driving mechanism, and the other end is connected with a baffle; when the telescopic rod is in a stretched state, the baffle is arranged vertically to the conveying belt; when the first separation cutoff device 212 starts to act, the driving mechanism drives the telescopic rod to stretch, so that the baffle is vertically arranged on the conveying belt, and plays a role in separating and stopping the glass bottles on the conveying belt, avoiding the glass bottles continuing to move forward on the conveying belt; when the middle collection mechanism 21 completes the collection, the first separation cutoff device 212 starts to restore the initial state: the driving mechanism drives the telescopic rod to contract, so that the baffle moves away from the conveying belt, and the glass bottles on the conveying belt 3 continue to move forward.

[0047] The first imaging device 211 comprises a workbench, the height of the workbench is higher than the height of the conveying belt; the workbench is provided with a clamping rotating part, a first imaging camera and a positioner, the clamping rotating part is connected with a driving part, and under the driving of the driving part, the clamping rotating part completes the clamping of the glass bottle, the self-rotation of the glass bottle, and the movement in the vertical direction and the horizontal direction.

[0048] Specifically, the clamping and rotating component includes a crossbeam mounted on the worktable, with several mechanical grippers connected to a drive source. Driven by the drive source, the mechanical grippers can grasp and release glass bottles; they can also move vertically to move the glass bottles; they can move horizontally to move the glass bottles closer to or away from the conveyor belt; and they can rotate the glass bottles to capture images while they are rotating. Connecting the mechanical grippers to the drive source to achieve these functions is a conventional technique, and its implementation principle will not be detailed here. Alternatively, one mechanical gripper can be connected to one drive source, with each gripper controlled independently, resulting in accurate movements, resistance to interference, and high stability; or several mechanical grippers can be connected to one drive source, reducing cost and component layout. The number of mechanical grippers is the same as the number of the first separation and cutoff device, so that when several glass bottles are separated and cut off, the mechanical grippers can simultaneously grab several glass bottles.

[0049] The working process of the first imaging device 211 is as follows: After the first separation and cutoff device 212 completes the separation and cutoff action, the clamping and rotating component grabs the glass bottle and lifts it vertically. While lifting it upward, it starts to rotate so that the glass bottle is in a state of rotation. When it is lifted and moved horizontally to the position of the locator, the locator sends a signal to the control area. The control area controls the first imaging camera to start taking pictures of the glass bottle and acquire images. After the pictures are taken, the clamping and rotating component stops rotating the glass bottle, then moves horizontally to directly below the conveyor belt, and then vertically downward to transport the glass bottle onto the conveyor belt for subsequent transport.

[0050] The central acquisition mechanism 21 uses the first separation and cutoff device 212 to cut off the glass bottles on the conveyor belt 3, preventing them from moving forward and positioning them in a specific position. This ensures that each glass bottle is in the same position and posture during shooting, providing a stable environment for shooting. Furthermore, the first imaging camera only starts to operate after the glass bottle is lifted to the position of the locator by the clamping and rotating component. The locator is set to provide the same detection reference point for each glass bottle, ensuring that the detection area is always located in the center of the field of view of the first imaging camera, further guaranteeing the stability during shooting.

[0051] Furthermore, the central acquisition mechanism 21 can have multiple first imaging cameras distributed at different locations, simultaneously capturing images of the glass bottle. This multi-camera setup allows for simultaneous imaging of different glass bottles, significantly improving acquisition efficiency through batch processing. Additionally, the multiple cameras can independently adjust parameters such as exposure time, gain, and spectral filtering based on the bottle's characteristics, including transmittance, color, and liquid level, ensuring optimal image quality for each bottle. Furthermore, damage to a single camera does not affect other cameras, enhancing the overall robustness of the detection process. More importantly, the multiple cameras can be designed for multispectral imaging, with complementary multispectral information overcoming the limitations of single-wavelength detection. For example, a near-infrared camera can penetrate the glass bottle wall to detect internal liquid levels, suspended matter, or microbial contamination (such as bacterial colonies); an ultraviolet camera can capture fluorescence reactions to detect fungal metabolites. Simultaneous acquisition by multiple cameras avoids the time difference required for multiple imaging operations in traditional single-spectral detection, ensuring strict alignment of multi-dimensional data.

[0052] In one specific embodiment, the number of both the middle collection mechanism 21 and the bottom collection mechanism 22 is set to at least two; and the number of glass bottles collected by a single middle collection mechanism 21 is greater than the number of glass bottles collected by a single bottom collection mechanism 22.

[0053] Specifically, in this embodiment, multiple middle acquisition mechanisms 21 and multiple bottom acquisition mechanisms 22 are set to enable simultaneous image acquisition of multiple glass bottles and multiple groups of glass bottles (multiple glass bottles as a group), which greatly improves the efficiency of the inspection process. At the same time, considering that bottle body imaging needs to be performed in a rotating state, while bottle bottom imaging only requires lifting the glass bottle to take pictures, the time for a single bottle body imaging is longer than the time for a single bottle bottom imaging. Therefore, the number of glass bottles acquired by a single middle acquisition mechanism 21 is greater than the number of glass bottles acquired by a single bottom acquisition mechanism 22, so that the production line rhythm is matched and the overall coordination of the production line rhythm is ensured.

[0054] In one specific implementation, such as Figure 3 As shown, the bottom acquisition mechanism 22 includes a gripping component 221 and a second imaging device 222, which are respectively disposed on both sides of the conveyor belt 3; the gripping component 221 is connected to the driving component, and under the drive of the driving component, the gripping component 221 completes the gripping of the glass bottle and the vertical movement.

[0055] Specifically, the gripping component 221 here can also be set as a mechanical claw, which is connected to the driving component to grip or release the glass bottle under the action of the driving component, as well as to perform vertical lifting and lowering movements. Since the bottom acquisition mechanism 22 is mainly for taking pictures of the bottom of the glass bottle, simply lifting the glass bottle is sufficient to take pictures of the bottom of the glass bottle.

[0056] The second imaging device 222 includes a second separation and cut-off device and a second imaging camera. A second counting sensor is provided on one side of the second separation and cut-off device. When the second counting sensor counts to a second threshold, it triggers the second separation and cut-off device to separate and cut off the glass bottle on the conveyor belt. The second imaging camera is connected to a moving component. Driven by the moving component, the second imaging camera moves to the bottom of the glass bottle and acquires an image of the bottom of the glass bottle.

[0057] The second counting sensor serves the same purpose as the first counting sensor: to ensure the consistency and accuracy of the results, and to trace back to the specific glass bottle(s). When the second counting sensor reaches the second threshold, its signal is sent to the control area. Upon receiving the signal, the control area then drives the second separation and cutoff device. The second separation and cutoff device includes a telescopic rod located on one side of the conveyor belt. One end of the telescopic rod is connected to the drive mechanism, and the other end is connected to a baffle. When the telescopic rod is in the extended state, the baffle is positioned perpendicular to the conveyor belt 3. When the second separation and cutoff device begins to operate, the drive mechanism drives the telescopic rod to extend, causing the baffle to be positioned perpendicularly on the conveyor belt 3, thus separating and cutting off the glass bottles on the conveyor belt 3 and preventing them from continuing to move forward on the conveyor belt 3. When the bottom acquisition mechanism 22 completes its acquisition, the second separation and cutoff device returns to its initial state: the drive mechanism drives the telescopic rod to retract, causing the baffle to move away from the conveyor belt, and the glass bottles on the conveyor belt 3 continue to move forward.

[0058] The working process of the second imaging device 222 is as follows: After the second separation and cut-off device completes the separation and cut-off action, the gripping component 221 grips the glass bottle and lifts it vertically. After lifting, the second imaging camera moves to the bottom of the glass bottle to start taking pictures and acquiring images. After the acquisition action is completed, the gripping component 221 places the lifted glass bottle on the conveyor belt 3, and the second separation and cut-off device returns to its initial state. The second imaging camera returns to its initial state (i.e., not below the glass bottle, but on the side of the conveyor belt 3), and the glass bottle continues to be transported on the conveyor belt 3.

[0059] In one specific embodiment, the top acquisition mechanism includes a third imaging device and a third counting sensor disposed above the conveyor belt 3. The third imaging device is an imaging camera. It should be noted that since capturing images of the top of the glass bottles is a routine and simple operation, and the glass bottles are conveyed vertically on the conveyor belt 3, no manipulation of the bottles is required. Image capture can be achieved simply during the conveying process. Therefore, compared to the middle acquisition mechanism 21 and the bottom acquisition mechanism 22, the top acquisition mechanism has a simpler structure, requiring only one imaging camera and one counting sensor to capture images of each glass bottle on the conveyor belt 3 as it arrives. The third counting sensor is used for counting, allowing identification of the specific bottle(s).

[0060] In one specific embodiment, the feeding area 1 includes a feeding platform, on which glass bottles are conveyed to the collection area 2 via a conveyor belt 3; the feeding platform includes a first conveyor belt and a second conveyor belt with opposite conveying directions, a first inclined block is provided between the end of the first conveyor belt and the second conveyor belt, and a second inclined block is provided between the end of the second conveyor belt and the transmission belt.

[0061] In this embodiment, the glass bottles are fed using a conveyor belt combined with their own gravity. This significantly reduces the horizontal footprint of the feeding platform. The transfer of glass bottles is achieved via the first and second tilting blocks, eliminating the need for additional motors, cylinders, or other power devices, thus saving costs. Gravity ensures consistent initial conditions for each slide, improving the repeatability of positioning accuracy. This feeding method reduces bottle jamming and blockages, and provides smooth transport. Compared to mechanical pushing, it reduces sudden speed changes and inertial impacts, making the bottles more stable and reducing the risk of collisions between them. Furthermore, the two tilting blocks have no moving parts, and wear is limited to the contact surface, resulting in long maintenance cycles and low maintenance costs.

[0062] Furthermore, the loading area 1 also includes a screw conveyor, which is mounted on the conveyor belt 3 so that glass bottles on the second conveyor belt can enter the conveyor belt 3 via the screw conveyor, with the conveying direction of the screw conveyor facing the collection area 2. This smoothly transitions the glass bottles from the second conveyor belt to the conveyor belt 3, ensuring that they face the collection area 2, avoiding jamming or accumulation caused by sudden changes in direction. While the inclined blocks rely solely on gravity to slide down, the screw conveyor provides power through active rotation, making the transfer of glass bottles more controllable, especially suitable for collection areas requiring precise positioning.

[0063] In one specific embodiment, a storage area is also included, which is connected to the collection area 2 via a conveyor belt 3. The storage area includes a defective area 4 and a qualified area 5. A rejection mechanism is provided on the conveyor belt 3 between the collection area 2 and the qualified area 5. The rejection mechanism is electrically connected to the control area. The control area sends the test results of each glass bottle to the rejection mechanism. The rejection mechanism is driven by the control area to reject defective glass bottles on the conveyor belt 3 and send them into the defective area 4.

[0064] The storage area further enhances the comprehensiveness of the automated production line inspection. Images acquired in acquisition area 2 are processed by the control area to identify defective and qualified glass bottles, which are then stored separately in designated areas. This reduces manual intervention in sorting, improves inspection efficiency, and lowers labor costs. Notably, after the image detection module in the control area sequentially detects fungi and / or bacteria on the bottle cap, body, and bottom, it outputs the corresponding test results for each bottle. Bottles containing fungi or bacteria are marked as defective, while those without are marked as qualified. Therefore, each bottle's result in the control area indicates whether it is qualified or defective. Defective bottles are rejected and moved to defective area 4, while qualified bottles are conveyed to qualified area 5 via conveyor belt 3.

[0065] Specifically, in this embodiment, a conveyor belt is provided between the defective area 4 and the conveyor belt 3. The rejection mechanism is located on one side of the conveyor belt 3. Specifically, the rejection mechanism includes a pusher, which is connected to a drive mechanism, which is connected to a control area. When the control area detects the acquired image, it provides information about the defective glass bottle. Subsequently, the drive mechanism drives the pusher to push the defective glass bottle from the conveyor belt 3 onto the conveyor belt, where it enters the defective area 4. To ensure production line efficiency, multiple sets of defective areas 4 can be set up, each set of defective areas 4 connected to the conveyor belt 3 by a conveyor belt, and several rejection mechanisms are also provided, with one rejection mechanism corresponding to one conveyor belt.

[0066] In one specific implementation, such as Figure 4 As shown, the qualified area 5 includes a storage rack 51 set on one side of the conveyor belt 3. A storage platform 52 is set on the storage rack 51. The surface of the storage platform 52 is flush with the surface of the conveyor belt 3. A gripping device 53 is set above the storage platform 52. The gripping device 53 is used to grip qualified glass bottles on the conveyor belt 3 and put them onto the storage platform 52.

[0067] Specifically, in this embodiment, the structure of the qualified area 5 is described in detail: the basic framework of the qualified area 5 is a storage rack 51, on which a storage platform 52 is provided. The storage platform 52 is flush with the surface of the transmission belt 3, which reduces positioning errors. Furthermore, the flush design eliminates height differences, so the gripping device 53 does not need to be adjusted in the vertical direction and can move directly along the horizontal path to the top of the glass bottle, significantly shortening the path and time of the gripping action. The gripping device 53 can be a robotic arm, a vacuum suction cup, or a gripper, etc.

[0068] Of course, to further improve the automation of the qualified zone 5, a storage tray is also installed on the storage platform. One storage tray can hold a group of glass bottles, and the number of glass bottles can be determined according to the actual situation. A fourth counting sensor and a third separation and cutoff device are installed on one side of the conveyor belt 3 corresponding to the qualified zone 5. The core of the fourth counting sensor is for counting, and the third separation and cutoff device has the same structure as the first separation and cutoff device. When the fourth counter counts to the fourth threshold, the third separation and cutoff device starts to operate, cutting off the glass bottles entering the qualified zone 5. Then, the gripping device 53 grabs the glass bottles in the qualified zone 5 and puts them onto the storage tray on the storage platform 52 to complete the batch operation. When the storage tray is full of glass bottles, the full storage tray can be unloaded to the unloading area by the tray lifting mechanism, and the empty storage tray is placed on the storage platform.

[0069] In one specific embodiment, a method of using a system for collecting samples from the inside of a glass bottle containing plant seedlings as described in any of the above claims includes the following steps:

[0070] S1: Load the glass bottles through loading area 1;

[0071] S2: When the glass bottles in the feeding area 1 are conveyed to the collection area 2 by the conveyor belt 3, the top, body and bottom of the glass bottles are photographed in sequence to obtain the collected images.

[0072] S3: The collected images of the bottle top, bottle body, and bottle bottom are sent to the image detection module in the control area to perform fungal detection on the bottle top and bottom, as well as fungal and bacterial detection on the bottle body.

[0073] S4: After inspecting the images of the bottle top, body, and bottom, glass bottles containing fungi or bacteria are marked as unqualified glass bottles, while glass bottles without fungi or bacteria are marked as qualified glass bottles; unqualified glass bottles enter unqualified area 4, and qualified glass bottles enter qualified area 5.

[0074] The automated acquisition method in this embodiment combines the distribution characteristics of fungi or bacteria inside the glass bottle with the structural characteristics of the fungi or bacteria themselves to detect different microbial species in different images. Ultimately, it achieves high accuracy, comprehensiveness, and efficiency in the identification of bacteria and fungi inside the glass bottle in an automated manner, making it suitable for the detection of large-scale, large-volume glass bottles.

[0075] The examples described herein are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the design concept of the present invention shall fall within the protection scope of the present invention.
