Description

Technical Field

[0001] This invention relates to the field of cell culture technology, and in particular to a dual-channel sample transfer device, a fully automated incubator, and a management system. Background Technology

[0002] An automated incubator is a biological incubator that can automatically transfer cultures. Compared to traditional incubators, the internal environment is more stable because the door does not need to be opened when taking or placing samples. Furthermore, all taking or placing actions in an automated incubator are controlled by a program and monitored by sensors, so the entire culture transfer process can be digitally recorded.

[0003] The typical use case for automated incubators is integration into an automated system, where the automated system provides motion commands and automatically stores and retrieves biological samples to be cultured in accordance with the biological culture requirements of the automated system. This means that biological samples can only flow according to a defined program flow.

[0004] However, the process of biological culture often involves many uncertainties, which require human intervention. To ensure the smooth and controllable operation of the process, automated systems tend to isolate the system from external operators to avoid human error or unauthorized operation, which results in low flexibility of the automated system.

[0005] In addition, the automatic incubator only uses a single channel for sample transfer, which results in low transfer efficiency and the inability to transfer samples in case of failure. Since there is no independent management system, the automatic incubator is not convenient to use independently, so the advantages of automatic incubator such as automatic transfer, low environmental disturbance and data history management cannot be fully realized independently. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects in the prior art, thereby providing a dual-channel sample transfer device, a fully automatic incubator and management system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dual-channel sample transfer device, the device comprising a first transfer channel mechanism, a second transfer channel mechanism, and a transfer unit;

[0009] The first transfer channel mechanism is located at a first position within the movement range of the transfer section and is used to import or export samples in a first manner.

[0010] The second transfer channel mechanism is located at a second position within the movement range of the transfer section, and is used to import or export samples via a first method;

[0011] The transfer unit is used to take a sample from the location of the culture sample and transfer it to the first transfer channel mechanism or the second transfer channel mechanism; it is also used to take a sample introduced by the first transfer channel mechanism or the second transfer channel mechanism and transfer it to the location of the culture sample.

[0012] In the aforementioned dual-channel sample transfer device, a dual-channel sample transfer architecture is realized through the first transfer channel mechanism and the second transfer channel mechanism. In conjunction with the transfer unit, the dual-channel parallel sample transfer operation of biological samples is realized, which significantly improves throughput efficiency. Furthermore, the first transfer channel mechanism and the second transfer channel mechanism achieve physical isolation between the two channels to avoid cross-interference.

[0013] In one embodiment, the first transfer channel mechanism includes a first sample tray, a first slider, a first guide, and an elastic component; the first guide is fixed to the bottom, and the first slider is slidably disposed on the first guide; one bottom side of the first sample tray is fixedly connected to the first slider, and one end side of the first sample tray is configured to cooperate with the elastic component.

[0014] With this configuration, the first sample tray serves as a sample carrying platform, allowing samples to be placed directly during import / export. The size of the first sample tray can be adapted to different petri dishes or containers. The first guide is fixed to the bottom, providing a precise linear sliding path for the first slider. The first slider is fixedly connected to the bottom of the first sample tray, ensuring that the first sample tray moves smoothly along the first guide, enabling the import or export of samples placed on the first sample tray. The low-resistance sliding of the first slider on the first guide allows the first sample tray to quickly extend or reset under the drive of the elastic component, shortening the single transfer cycle.

[0015] In one embodiment, the first transfer channel mechanism further includes a door cover, and the other end of the first sample tray is connected to the door cover.

[0016] With this configuration, the door cover acts as a physical barrier to the transfer channel in the first transfer channel mechanism, controlling the entry and exit of samples; at the same time, the door cover also acts as a pusher, allowing the user to directly control the movement of the first sample tray by pushing the front door cover during the sample import / export process.

[0017] In one embodiment, the elastic component includes an elastic element, an electrically controlled locking actuator, and a locking element;

[0018] The locking component is located at the end of the first sample tray. One side of the elastic component is fixedly connected to the locking component, and the other side is configured to cooperate with the electrically controlled locking actuator.

[0019] With this configuration, the elastic element is fixed to the locking element, and the electrically controlled locking actuator controls the engagement state of the locking element, so that when the power is off, the elastic element pushes the first sample tray outward; when the power is on, the electrically controlled locking actuator locks the first sample tray.

[0020] In one embodiment, the second transfer channel mechanism includes a first door assembly, a conveyor belt assembly, a second slider, a second sample tray, a second door assembly, and a housing;

[0021] An opening is provided on the side of the housing facing the transfer section;

[0022] The first door assembly is located inside the opening and is used to control its opening and closing state.

[0023] The conveyor belt assembly is located at the bottom of the housing and inside the first door assembly;

[0024] The second sliding member is slidably disposed on the conveyor belt assembly. The bottom side of the second sample tray facing the transfer section is connected to the second sliding member, and the other side is connected to the second door assembly.

[0025] In this configuration, the shell serves as a sample transfer channel, transferring samples from the automatic inner door opening facing the transfer section to the outlet on the other side. The first door assembly controls the opening and closing of the opening, and the second door assembly controls the opening and closing of the outlet. The second sample tray serves as a sample carrying platform, directly placing samples during import / export. The size of the second sample tray can be adapted to different petri dishes or containers. When importing / exporting samples on the second sample tray, the first door assembly and the second door assembly are alternately controlled to block the exchange of air between the inside and outside, ensuring unidirectional airflow isolation.

[0026] In one embodiment, the first door assembly includes a first motor, a rotating part, a drive wheel, a first door body, a drive slide, a guide pulley, a guide bar, and a guide groove;

[0027] The output end of the first motor is connected to one end of the rotating part, and the other end of the rotating part is provided with a drive wheel, which is fitted into a drive groove on the first door body.

[0028] The first door body is also provided with guide pulleys on both sides for positioning along the direction of movement;

[0029] The guide pulley is slidably mounted on the guide bar; the guide bar has at least one guide groove.

[0030] With this configuration, the first motor outputs rotational motion, and the rotating part converts the circular motion into linear displacement of the drive wheel. The drive wheel slides along the drive groove, pushing the first door body to rise and fall, thereby achieving smooth lifting and reliable sealing of the first door body. The curved design of the drive groove accurately converts the circular motion of the rotating part into the vertical displacement of the first door body, avoiding jamming. The lever effect of the rotating part amplifies the output force of the first motor by 3-5 times, allowing a small-power motor to drive the relatively heavy first door body, thereby reducing the size and power of the first motor. When the rotating part is in a vertical state, the first door body is fully open / fully closed, and gravity forms a self-locking mechanism to prevent the first door body from accidentally sliding and causing poor sealing. The guide grooves on both sides distribute the gravity load of the first door body, preventing single-point wear. The movement trajectory of the guide pulley can also be constrained to ensure that the first door body and the opening are completely fitted together.

[0031] In one embodiment, the second door assembly includes a second door hinge and a second door, and the other side of the second sample tray is connected to the second door via the second door hinge.

[0032] With this configuration, the second door assembly, through the mechanical linkage design between the second door body pivot and the second door body, forms a motion coupling with the second sample tray, which significantly optimizes operating efficiency, sealing reliability, and system safety.

[0033] In one embodiment, the conveyor belt assembly includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, a moving motor, and a second guide portion; the synchronous belt is wound between the first synchronous pulley and the second synchronous pulley, the moving motor is connected to either the first synchronous pulley or the second synchronous pulley, and the second sliding member is disposed on the synchronous belt and cooperates with the second guide portion.

[0034] With this configuration, the moving motor achieves accurate control of the sliding position of the second sample tray through frequency conversion control, and shortens the transfer time; the conveyor belt assembly can also achieve automatic sliding out or retraction of the second sample tray 204.

[0035] A fully automated incubator includes a chamber, a culture rack, a sample transfer device, and a sample management mechanism;

[0036] The enclosure is used to provide space for sample culture;

[0037] The culture carrier is housed inside the chamber and is used to culture the sample;

[0038] The sample transfer device is disposed inside the box and located on one side of the culture rack, and is used to transfer samples from the culture rack and to introduce samples into the culture rack.

[0039] The sample management mechanism is used to manage and record the operation permissions for transferring or importing samples using the sample transfer device; it is also used to manage and record the operation permissions for the opening and closing status of the box.

[0040] In the aforementioned fully automated incubator, the sealed space of the chamber and the dual-channel transfer mechanism (first transfer channel mechanism and second transfer channel mechanism) of the sample transfer device form a physical-logical dual isolation, ensuring that the culture environment (temperature, humidity, CO2 concentration) is completely decoupled from external interference; furthermore, the transfer part of the sample transfer device is located on the side of the culture carrier, minimizing the gripping stroke and reducing the time spent on single sample transfer; and the sample management mechanism controls the opening and closing of the chamber to avoid environmental fluctuations caused by unauthorized operations.

[0041] A management system for a fully automated incubator, comprising: a user management module, a sample management module, an operation management module, and a data management module;

[0042] The user management module is used to create administrator accounts and ordinary user accounts; it is also used to automatically assign sample operation permissions according to the account level after identifying and verifying the identity and permissions of the current user. The sample operation permissions include the operation permissions of the first transmission channel mechanism, the second transmission channel mechanism, and the box.

[0043] The sample management module is used to establish the association between the sample and the account created by the user management module; it is also used to verify whether the current user has the right to operate the target sample after user identity recognition and permission verification; and it is also used to record the transfer path of the sample between the first transfer channel mechanism, the second transfer channel mechanism, the transfer section and the culture carrier.

[0044] The operation management module is used to control the operation of the first transmission channel mechanism, the second transmission channel mechanism, and the box according to the sample operation permissions corresponding to the current user's account level;

[0045] The data management module is used to record user operations, sample movement, and device status changes in real time; it is also used to query historical operation records and generate reports.

[0046] The aforementioned management system significantly improves the operational safety and efficiency of the fully automated incubator. The user management module implements tiered account access control, ensuring that only authorized users can operate the first transfer channel mechanism, the second transfer channel mechanism, or the incubator itself, effectively preventing unauthorized access and misoperation. The sample management module establishes a strong association between samples and users, accurately tracking the transfer path of samples between the transfer channel, transfer section, and culture rack after authorization verification, avoiding cross-contamination and supporting dual-channel parallel processing. The operation management module dynamically controls equipment operation based on permissions, optimizing the sample import / export process and improving throughput efficiency. Simultaneously, the data management module records user operations, sample movement, and equipment status changes in real time, and can query historical data to generate reports, enhancing the system's traceability, compliance, and management transparency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0062] This invention provides a dual-channel sample transfer device, which constructs a dual-channel parallel sample transfer architecture. On the one hand, it realizes dual-channel parallel sample transfer operation of biological samples, significantly improving throughput efficiency; on the other hand, it also realizes that the two channels are physically isolated to avoid cross-interference.

[0063] like Figure 1-7 As shown, specifically, the dual-channel sample transfer device includes a first transfer channel mechanism 100, a second transfer channel mechanism 200, and a transfer unit 300;

[0064] The first transfer channel mechanism 100 is located at a first position within the movement range of the transfer unit 300, and is used to import or export the sample 400 in a first manner;

[0065] The second transfer channel mechanism 200 is located at a second position within the movement range of the transfer unit 300, and is used to import or export the sample 400 in a second manner;

[0066] The transfer unit 300 is used to take the sample 400 from the position of the culture sample 400 and transfer it to the first transfer channel mechanism 100 or the second transfer channel mechanism 200; it is also used to take the sample 400 introduced by the first transfer channel mechanism 100 or the second transfer channel mechanism 200 and transfer it to the position of the culture sample 400.

[0067] It should be noted that the first method can be either a manual method or an automatic method, and the second method can be either a manual method or an automatic method.

[0068] The first transfer channel mechanism 100 and the second transfer channel mechanism 200 are located at any position within the movement range of the transfer unit 300, and can be adjusted according to the specific structural layout of the application.

[0069] The first transfer channel mechanism 100 includes a first sample tray 101, a first sliding member 102, a first guide member 103, and an elastic component 104; the first guide member 103 is fixed to the bottom, and the first sliding member 102 is slidably disposed on the first guide member 103; one side bottom of the first sample tray 101 is fixedly connected to the first sliding member 102, and one side end of the first sample tray 101 is configured to cooperate with the elastic component 104.

[0070] For example, the first sliding member 102 is a sliding block, the first guide member 103 is a guide rail, and the elastic member 1041 is a spring.

[0071] The first transfer channel mechanism 100 also includes a door cover plate 105, and the other end of the first sample tray 101 is connected to the door cover plate 105.

[0072] The elastic component 104 includes an elastic element 1041, an electrically controlled locking actuator 1042, and a locking element 1043;

[0073] The locking member 1043 is disposed at the end of the first sample tray 101. One side of the elastic member 1041 is fixedly connected to the locking member 1043, and the other side is configured to cooperate with the electrically controlled locking actuator 1042.

[0074] For example, the electrically controlled locking actuator 1042 is an electrically controlled retractor.

[0075] When the first transfer channel mechanism 100 is in the locked state, the electrically controlled locking actuator 1042 remains energized and tightly engages with the locking actuator 1043, so the first sample tray 101 remains in the initial state, and at the same time, the door cover 105 is in the closed state.

[0076] When sample 400 needs to be imported, the electrically controlled locking actuator 1042 is de-energized and separates from the locking member 1043. The first sample tray 101 moves outward along the first guide member 103 under the elastic force of the elastic member 1041. When it moves to the end of the first guide member 103, the current user places sample 400 on the first sample tray 101. Then, the current user gently pushes the door cover 105, causing the first sample tray 101 to reset inward along the first guide member 103. At the same time, the electrically controlled locking actuator 1042 is re-energized. Under manual pushing, the locking member 1043 re-engages with the electrically controlled locking actuator 1042, and the first sample tray 101 returns to its initial state. Afterward, the transfer unit 300 takes sample 400 from the first sample tray 101 and transfers it to the position of the culture sample 400.

[0077] When sample 400 needs to be transferred out, the transfer unit 300 takes sample 400 from the position of culture sample 400 and transfers it to the first sample tray 101. Then, the electrically controlled locking actuator 1042 is de-energized and separates from the locking member 1043. The first sample tray 101 moves outward along the first guide member 103 under the elastic force of the elastic member 1041. When it moves to the end of the first guide member 103, the current user takes sample 400 from the first sample tray 101. Then, the current user gently pushes the door cover 105, so that the first sample tray 101 resets inward along the first guide member 103. At the same time, the electrically controlled locking actuator 1042 is re-energized. Under manual pushing, the locking member 1043 re-engages with the electrically controlled locking actuator 1042, and the first sample tray 101 returns to its initial state.

[0078] The second transfer channel mechanism 200 includes a first door assembly 201, a conveyor belt assembly 202, a second sliding member 203, a second sample tray 204, a second door assembly 205, and a housing 206;

[0079] The housing 206 has an opening 2061 on the side facing the transfer part 300;

[0080] The first door assembly 201 is located inside the opening 2061 and is used to control its opening and closing state;

[0081] The conveyor belt assembly 202 is disposed at the bottom of the housing 206 and located inside the first door assembly 201;

[0082] The second sliding member 203 is slidably disposed on the conveyor belt assembly 202. The bottom side of the second sample tray 204 facing the transfer part 300 is connected to the second sliding member 203, and the other side is connected to the second door assembly 205.

[0083] A sterilization section 207 is provided inside the housing 206 facing the second sample tray 204, and the second sample tray 204 after the sample 400 is transferred is sterilized by the sterilization section 207.

[0084] The sterilization unit 207 automatically disinfects the surface of the second sample tray 204 after the sample 400 is transferred, eliminating the risk of cross-contamination.

[0085] For example, the sterilization section 207 uses a sterilization lamp.

[0086] The first door assembly 201 includes a first motor 2011, a rotating part 2012, a drive wheel 2013, a first door body 2014, a drive slide 2015, a guide pulley 2016, a guide bar 2017, and a guide groove 2018;

[0087] The output end of the first motor 2011 is connected to one end of the rotating part 2012, and the other end of the rotating part 2012 is provided with a drive wheel 2013. The drive wheel 2013 is fitted into the drive groove 2015 on the first door body 2014.

[0088] The first door body 2014 is also provided with guide pulleys 2016 on both sides for moving in the direction of movement;

[0089] The guide pulley 2016 is slidably disposed on the guide bar 2017; the guide bar 2017 has at least one guide groove 2018.

[0090] The opening 2061 is located on the vertical surface of the housing 206, so the first door 2014 is also located in the vertical direction. The guide strip 2017 is located on both sides of the first door 2014, and the guide groove 2018 is located on the side facing the first door 2014. The guide pulley 2016 is fitted in the guide groove 2018.

[0091] The drive slide 2015 is arranged horizontally on the upper side of the first door body 2014, and the length of the rotating part 2012 is equal to the distance between the drive slide 2015 and the first motor 2011.

[0092] When the first door assembly 201 is in a sealed state, the first door body 2014 completely covers the opening 2061, and an airtight seal is formed by the inner door seal.

[0093] When it is necessary to open the opening 2061, the first motor 2011 rotates clockwise, driving the rotating part 2012 to rotate clockwise. The drive wheel 2013 slides to the left along the drive groove 2015. After sliding to the end of the leftward movement, the rotating part 2012 lifts the opening 2061 until the rotating part 2012 is in an upward vertical state (at this time, the drive wheel 2013 is in the center position of the drive groove 2015), which means that the opening 2061 is fully opened.

[0094] When it is necessary to close the opening 2061, the rotating part 2012 is in an upward vertical state (at this time, the drive wheel 2013 is in the center position of the drive groove 2015). The first motor 2011 rotates clockwise, driving the rotating part 2012 to rotate clockwise. The drive wheel 2013 slides to the right along the drive groove 2015. After sliding to the end of the rightward movement, the rotating part 2012 gradually lowers the opening 2061 until the rotating part 2012 is in a downward vertical state (at this time, the drive wheel 2013 is in the center position of the drive groove 2015), which means that the opening 2061 is completely closed.

[0095] It should be noted that the opening 2061 can also be opened by rotating the first motor 2011 clockwise and closed by rotating the first motor 2011 counterclockwise; or, the opening 2061 can be opened by rotating the first motor 2011 counterclockwise and closed by rotating the first motor 2011 clockwise.

[0096] The second door assembly 205 includes a second door pivot 2051 and a second door 2052. The other side of the second sample tray 204 is connected to the second door 2052 via the second door pivot 2051.

[0097] When the second sample tray 204 extends outward, the second door 2052 rotates counterclockwise along the second door pivot 2051, so that the second door 2052 is in an open state.

[0098] When the second sample tray 204 retracts inward, the second door 2052 rotates clockwise along the second door pivot 2051, so that the second door 2052 is in a closed state.

[0099] The conveyor belt assembly 202 includes a first synchronous pulley 2021, a second synchronous pulley 2022, a synchronous belt 2023, a moving motor 2024, and a second guide part 2025; the synchronous belt 2023 is wound between the first synchronous pulley 2021 and the second synchronous pulley 2022, the moving motor 2024 is connected to either the first synchronous pulley 2021 or the second synchronous pulley 2022, and the second sliding member 203 is disposed on the synchronous belt 2023 and is configured to cooperate with the second guide part 2025.

[0100] The mobile motor 2024 drives either the first synchronous wheel 2021 or the second synchronous wheel 2022 to rotate counterclockwise, thereby driving the second sliding member 203 to move outward along the second guide portion 2025, and at the same time the second sample tray 204 extends outward.

[0101] The mobile motor 2024 drives either the first synchronous wheel 2021 or the second synchronous wheel 2022 to rotate clockwise, thereby driving the second sliding member 203 to move inward along the second guide portion 2025, and at the same time the second sample tray 204 retracts inward.

[0102] When the second transfer channel mechanism 200 is in the locked state, the second slider 203 is located on the far right of the conveyor belt assembly 202, so the second sample tray 204 also remains in the initial state. At the same time, the second door assembly 205 and the first door assembly 201 are in the closed state.

[0103] When sample 400 needs to be imported, the conveyor belt assembly 202 rotates counterclockwise, causing the second slider 203 to move to the left. At the same time, the second sample tray 204 extends outward, and the second door assembly 205 gradually opens. The user places sample 400 on the second sample tray 203 (at this time, the first door assembly 201 is in the closed state). Then, the conveyor belt assembly 202 rotates clockwise, causing the second sample tray 203 to reset inward, and the first sample tray 101 returns to its initial state. After that, the conveyor belt assembly 202 stops operating, and the second door assembly 205 and the first door assembly 201 are in the closed state. The first door assembly 201 gradually opens until the opening 2061 is fully open. The transfer part 300 passes through the opening 2061 to take sample 400 from the second sample tray 203 and transfer it to the position of the culture sample 400. After the sample is taken away, the first door assembly 201 closes, thus completely closing the opening 2061.

[0104] When sample 400 needs to be transferred out, the transfer unit 300 takes sample 400 from the position of culture sample 400. At the same time, the first door assembly 201 is in the open state and the second door assembly 205 is in the closed state. The opening 2061 is fully open, and the sample is transferred through the opening 2061 to the second sample tray 203. After that, the first door assembly 201 is closed, that is, the opening 2061 is completely closed. The conveyor belt assembly 202 rotates counterclockwise, driving the second slider 203 to move to the left. At the same time, the second sample tray 204 extends outward, and the second door assembly 205 gradually opens. The current user takes away the sample 400 placed on the second sample tray 203. After that, the conveyor belt assembly 202 rotates clockwise, causing the second sample tray 203 to reset inward. The first sample tray 101 returns to its initial state. After that, the conveyor belt assembly 202 stops operating, and the first door assembly 201 is in the closed state.

[0105] It should be noted that the transfer unit 300 achieves three-dimensional spatial positioning through a joint structure, accurately grasping the sample 400; the first transfer channel mechanism 100 and the second transfer channel mechanism 200 are within the movement radius of the transfer unit 300.

[0106] For example, the transfer unit 300 employs a robotic arm.

[0107] The transfer unit 300 is provided with a monitoring scanning dock 301 on its side. Before and after each sample 400 is picked up by the transfer unit 300, the monitoring scanning dock 301 can scan the unique code on the sample 400 to confirm whether the obtained sample is the required sample and record it.

[0108] This invention also provides a fully automated incubator that ensures complete decoupling of the culture environment (temperature, humidity, CO2 concentration) from external interference, effectively avoiding environmental fluctuations caused by unauthorized operations, thereby achieving efficient, stable and safe biological sample culture and transfer.

[0109] like Figure 8-10 As shown, specifically, the fully automated incubator includes a chamber body 500, a culture rack 600, a sample transfer device, and a sample management mechanism 700;

[0110] The box 500 is used to provide space for the culture of sample 400;

[0111] The culture carrier 600 is set inside the box 500 and is used to culture the sample 400;

[0112] The sample transfer device is disposed inside the housing 500 and located on one side of the culture carrier 600, and is used to transfer the sample 400 from the culture carrier 600 and to introduce the sample 400 into the culture carrier 600.

[0113] The sample management mechanism 700 is used to manage and record the operation permissions for transferring or importing samples 400 by the sample transfer device; it is also used to manage and record the operation permissions for the opening and closing status of the box 500.

[0114] The sample transfer device adopts the structure of the above embodiment.

[0115] The culture carrier 600 is located inside the box 500, and the transfer part 300 is located on the left side of the culture carrier 600. The transfer part 300, the first transfer channel mechanism 100 and the second transfer channel mechanism 200 are arranged in a triangle so that the distance from the transfer part 300 to any channel is the same. The rotation radius of the transfer part 300 covers the entire area, reducing the time consumed for single sample transfer.

[0116] A third door 501 and a fourth door 502 are provided on one side of the box 500;

[0117] The third door 501 serves as an inner sealing door and is located on one side of the housing 500;

[0118] The fourth door 502 serves as an external sealing door, located on one side of the housing 500 and outside the third door 501, and also functions as a management door.

[0119] After the third door 501 is opened, the interior of the chamber 500 is completely exposed to the outside air, and the chamber 500 can exchange with the outside gas. At this time, the current user can perform maintenance on the interior of the chamber 500 or process the sample 400 on the culture carrier 400 of the chamber 500, including the transfer of the sample 400 on the culture carrier 400, the removal of the sample 400, and the addition of the sample 400.

[0120] The fourth door 502 is the outer safety door of the housing 500, which serves to restrict door opening and provide insulation; the fourth door 502 is only opened when the system allows it to be opened.

[0121] The sample management mechanism 700 includes a first sensor 701, a second sensor 702, an electric lock 703, a reader 704, and an interactive interface 705.

[0122] A first sensor 701 is installed on the inner side of the housing 500 near the third door 501 to monitor the opening and closing status of the third door 501.

[0123] The first sensor 701 collects the physical displacement signal of the third door 501 in real time, converts it into an electrical signal and transmits it to the sample management mechanism 700; if the first sensor 701 detects that the third door 501 is abnormally opened, it triggers the sample management mechanism 700 to start emergency measures to avoid sample inactivation.

[0124] A second sensor 702 and an electric lock 703 are installed on the inner side of the housing 500 near the fourth door 502. The second sensor 702 monitors the opening and closing status of the fourth door 502, and the electric lock 703 controls the locking or opening of the fourth door 502.

[0125] The second sensor 702 monitors the displacement of the fourth door 502, and the electric lock 703 receives instructions from the sample management mechanism 700 to lock / unlock.

[0126] The side of the housing 500 is also equipped with a reader 704, which identifies sample information and user information in the form of barcodes, QR codes, numbers, text, special patterns, NFC identification tags, Bluetooth, etc., and converts the identified physical information into digital IDs and transmits them to the sample management agency 700.

[0127] The side of the enclosure 500 is also provided with an interactive interface 705, through which device information is displayed and functions are interacted with by the current user.

[0128] The interactive interface 705 can plot the cultivation parameter curves (temperature / humidity / O2) in real time, and automatically pop up a warning when the threshold is exceeded; it can also reduce the error rate by 60% through visual operation guidance.

[0129] The interactive interface 705 is a touch screen display.

[0130] The working process of the fully automatic incubator of this invention:

[0131] The process of importing sample 400 through the first transfer channel mechanism 100:

[0132] The electrically controlled locking actuator 1042 and locking member 1043 separate, so that the first sample tray 101 extends along the first guide member 103 under the push of the elastic member 1041. The user places the sample 400 on the first sample tray 101. The user pushes the door cover 105, that is, pushes back the first sample tray 101. The electrically controlled locking actuator 1042 and locking member 1043 re-engage, and the door cover 105 is in the closed state, blocking the inside and outside of the box 500. At this time, the sample 400 is transferred from the transfer part 300 to the culture carrier 600.

[0133] The process of exporting sample 400 through the first transfer channel mechanism 100:

[0134] Sample 400 is transferred from transfer part 300 to first sample tray 101. Then, the electronically controlled locking actuator 1042 and locking member 1043 separate, so that the first sample tray 101 extends along the first guide member 103 under the push of elastic member 1041. User sample 400 is taken off from the first sample tray 101. The current user pushes back the first sample tray 101, and the electronically controlled locking actuator 1042 and locking member 1043 re-engage.

[0135] The process of importing sample 400 through the second transfer channel mechanism 200:

[0136] The conveyor belt assembly 202 rotates counterclockwise, moving the second sample tray 204 along the second guide section 2025 out of the housing 206. At the same time, the second door assembly 205 opens while the first door assembly 201 is closed, meaning the inside and outside of the housing 500 are not connected. The user places the sample 400 on the second sample tray 204. The conveyor belt assembly 202 rotates clockwise, moving the second sample tray 204 along the second guide section 2025 back into the housing 206. Simultaneously, the second door assembly 205 closes while the first door assembly 201 remains closed. At this point, the sample 400 is sealed inside the housing 206. With the first door assembly 201 open and the second door assembly 205 closed, the inside of the housing 500 is interconnected. The sample 400 moves from the opening 2061 through the transfer section 300 to the culture rack 600. The first door assembly 201 is closed, and the ultraviolet sterilization lamp is turned on to sterilize the second sample tray 204.

[0137] The process of exporting sample 400 through the second transfer channel mechanism 200:

[0138] The first door assembly 201 is open and the second door assembly 205 is closed, allowing communication within the housing 500. Sample 400 is moved by the transfer unit 300 and placed on the second sample tray 204. The first door assembly 201 is closed and the second door assembly 205 is still closed. The second sample tray 204 moves along the second guide 2025 and extends out of the housing 206. Simultaneously, the second door assembly 205 is open while the first door assembly 201 is closed, meaning there is no communication between the inside and outside of the housing 500. The user removes sample 400 from the second sample tray 204. The conveyor belt assembly 202 rotates clockwise, and the second sample tray 204 moves along the second guide 2025 and retracts into the housing 206. At the same time, the second door assembly 205 is closed and the first door assembly 201 is still closed. The ultraviolet sterilization lamp is turned on to sterilize the second sample tray 204.

[0139] This invention also provides a management system that can significantly improve the operational safety and efficiency of fully automated incubators.

[0140] like Figure 11 As shown, specifically, the management system includes: a user management module, a sample management module, an operation management module, and a data management module;

[0141] The user management module is used to create administrator accounts and ordinary user accounts; it is also used to automatically assign sample operation permissions according to the account level after identifying and verifying the identity and permissions of the current user. The sample operation permissions include the operation permissions of the first transmission channel mechanism 100, the second transmission channel mechanism 200, and the box 500.

[0142] It is also used to create a super administrator account with the highest privileges. The super administrator's privileges include creating administrator accounts and ordinary user accounts, retrieving, viewing, deleting, and modifying any data in the system, and allowing arbitrary functional operations on the device.

[0143] The sample management module is used to establish the association between sample 400 and the account created by the user management module; it is also used to verify whether the current user has the right to operate the target sample after user identity recognition and permission verification; it is also used to record the transfer path of sample 400 between the first transfer channel mechanism 100, the second transfer channel mechanism 200, the transfer unit 300 and the culture carrier 400.

[0144] The operation management module is used to control the operation of the first transmission channel mechanism 100, the second transmission channel mechanism 200, and the box 500 according to the sample operation permissions corresponding to the current user's account level;

[0145] The data management module is used to record user operations, sample movement, and device status changes in real time; it is also used to query historical operation records and generate reports.

[0146] The user management module is used to establish a hierarchical account system (super administrator / administrator / regular user), verify permissions through identity recognition (such as QR code / NFC scanning of reader 704), and dynamically allocate sample operation permissions.

[0147] The super administrator has the highest privileges and the privileges to create administrators and ordinary users. Administrators have full privileges (including operation of the first transmission channel mechanism 100, the second transmission channel mechanism 200, and the box 500); ordinary users are limited to manual channels (such as the elastic sliding operation of the first transmission channel mechanism 100).

[0148] After a user logs in by scanning a QR code, the system automatically unlocks the conveyor belt assembly 202 of the second transmission channel mechanism 200, but prevents it from opening the fourth door 502 (i.e., the management door) outside the box 500.

[0149] The sample management module is used to establish a strong binding relationship between the sample 400 and the user, enabling full lifecycle tracking; it associates each sample 400 with the creator's account through a unique code (such as a QR code); after permission verification, the system verifies whether the user can operate the target sample (e.g., user A can only transfer the samples he / she created); it also records the entire path of the sample 400 from import to export (e.g., "sample Y: first transfer channel mechanism 100 → transfer unit 300 → culture carrier 600 position 3"); and it maps the transfer path to the data management module in real time to generate a visual trajectory map to help optimize the grabbing logic of the transfer unit 300.

[0150] The operation management module dynamically controls device operation based on permissions, optimizes the sample import / export process, schedules the corresponding transmission channel based on the user's permission level, and also integrates sensor (such as the inner door monitoring sensor 701) feedback status. Abnormal operations (such as unauthorized opening of the box 500) automatically interrupt the process and record it.

[0151] For ordinary users: only the elastic component 104 of the first transfer channel mechanism 100 is triggered (power failure releases the sample tray), making the operation simple and quick.

[0152] Super Administrator / Administrator: Can initiate the fully automatic process of the second transmission channel mechanism 200 (such as the opening and closing linkage of the first door component 201 and the movement of the synchronous belt 2023).

[0153] The data management module is used to record operation, sample and equipment data in real time and supports full-chain auditing.

[0154] User operation log: such as "User B operated the second transfer channel mechanism 200 to import sample Z at 10:00 on 2025-08-18".

[0155] Sample movement record: path data (such as the coordinates and timestamps of the sample from channel 200 through transfer unit 300 to carrier 600).

[0156] Generate customized reports on demand (such as the "Daily Operation Audit Report"), and support exporting to PDF / Excel formats, covering permission compliance (such as the matching degree between user operations and permissions) and sample traceability chain.

[0157] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
