[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0047] The purpose of this invention is to provide a live cell workstation that can reduce the number of times the door is opened and closed, thereby reducing the impact on the internal environment of the incubator.

[0048] It should be noted that in this embodiment, the direction of X in the accompanying drawings is defined as the first direction.

[0049] To achieve the above objectives, the present invention provides the following technical solution:

[0050] Please see Figures 1 to 4 This embodiment provides a live cell workstation, including: a cabinet 100, a sterilization component, a turntable tray assembly 300, and a robotic arm assembly 400; the cabinet 100 has an internal receiving cavity, and two side walls of the cabinet 100 are respectively provided with an openable and closable door 110 and a transfer door 120, and a culture dish tray 130 is provided on the outside of the cabinet 100; the sterilization component is located at the bottom of the cabinet 100 and is used to spray sterilization spray into the receiving cavity; the turntable tray assembly 300 is rotatably disposed inside the receiving cavity and is used to place culture dishes; the robotic arm assembly 400 is installed inside the receiving cavity and is used to transfer culture dishes between the turntable tray assembly 300 and the culture dish tray 130, and the culture dishes pass through the transfer door 120.

[0051] In this embodiment, the interior space of the cabinet 100 is divided into two parts. One part is a receiving cavity for accommodating the turntable bracket assembly 300 and the robotic arm assembly 400. The inside of this receiving cavity serves as the incubation chamber of the workstation. The other part is a smaller cavity located at the bottom, which is used to install the disinfection component and the electrical control component. The disinfection component can spray disinfectant into the receiving cavity to sterilize and disinfect the receiving cavity, which serves as the incubation chamber. The electrical control component controls the operation and movement of each component in the entire workstation.

[0052] It should be noted that in this embodiment, a switch door 110 and a transfer door 120 are respectively provided on the front and right side walls of the cabinet 100. The switch door 110 is larger in size and protects the entire internal space of the cabinet 100. It is generally used to open when inspecting or maintaining internal components or cleaning the internal space of the cabinet 100. The transfer door 120 is smaller in size and is only opened when placing a culture dish into the receiving cavity or when removing a culture dish from the receiving cavity. Due to its smaller size, it has less impact on the inside of the receiving cavity each time it is opened. In addition, in this embodiment, a culture dish holder 130 is provided on the outside of the cabinet 100 near the transfer door 120 to facilitate the placement or removal of culture dishes. Of course, the positions of the switch door 110 and the transfer door 120 can be adjusted appropriately according to the actual situation, and their sizes can also be changed. However, it is necessary to ensure that the size of the transfer door 120 is small to prevent its opening or closing from affecting the environment inside the receiving cavity.

[0053] In this embodiment, the turntable bracket assembly 300 can specifically be a rotatable frame structure 410, which can rotate around the vertical direction and can hold several layers of culture dishes. At the same time, the robotic arm assembly 400 can transfer the culture dishes on the turntable bracket assembly 300. For example, it can transfer the culture dishes placed on the culture dish holder 130 to the receiving cavity and place them in an empty position on the turntable bracket assembly 300. The robotic arm assembly 400 can also transfer the cultured surface on the turntable bracket assembly 300 to the culture dish holder 130 outside the cabinet 100. Of course, during the above process, the transfer door 120 will be opened and closed after the robotic arm assembly 400 completes its action.

[0054] In other words, the cabinet 100 has a large-aperture door 110 and a transfer door 120 used only for transferring culture dishes. Inside the cabinet 100 are a sterilization assembly, a turntable tray assembly 300, and a robotic arm assembly 400. The turntable tray assembly 300 can hold several culture dishes, and the sterilization assembly continuously sterilizes and moisturizes the culture dishes within the container, thus ensuring a suitable environment for their survival. When it is necessary to place culture dishes into the cabinet 100 or remove them from the outside, this can be achieved through the robotic arm assembly 400 inside the container. Furthermore, the robotic arm assembly 400 only passes through the open transfer door 120 each time a culture dish is transferred. Component 400 can pass the culture dish through the open transfer door 120 and place it on the culture dish holder 130, or it can transfer the culture dish that has been placed on the culture dish holder 130 in advance through the transfer door 120 to the turntable holder assembly 300. In addition, after the transfer of the culture dish is completed, the transfer door 120 will be closed and will not be opened again. In this embodiment, the switch door 110 is only used for equipment maintenance or cleaning inside the cabinet 100. With this setting, it is not necessary to open the switch door 110 every time a culture dish is placed or taken out; only the smaller transfer door 120 needs to be opened. This can minimize the impact on the internal environment inside the cabinet 100, thereby affecting the culture of cells in the culture dish.

[0055] In one possible implementation, the disinfection assembly includes: a water tank 210, a hydrogen peroxide atomizing device 220, and a circulation pump 230; the water tank 210 is used for storing humidified pure water; the hydrogen peroxide atomizing device 220 is connected to the water tank 210, and is used to store disinfectant and atomize it along with the introduced humidified pure water before discharging it into the receiving cavity; the circulation pump 230 is located on the connecting pipe between the water tank 210 and the atomizing device, and is used to pump the humidified pure water in the water tank 210 into the atomizing device; one end of the circulating air path is connected to the atomizing device, and the other end is connected to the inside of the receiving cavity, and the circulating air path is used to introduce the atomized disinfectant and humidified pure water into the receiving cavity for sterilization.

[0056] Specifically, such as Figure 1As shown, the disinfection assembly is located at the bottom of the cabinet 100. The water box 210 can hold an appropriate amount of water. The water box 210 is connected to the hydrogen peroxide atomizing device 220 through the circulation pump 230. The hydrogen peroxide atomizing device can store the disinfectant hydrogen peroxide and can atomize all the liquid passing through it. In this way, the water and liquid hydrogen peroxide in the water box 210 can be atomized into water vapor, and after mixing, they are evenly introduced into the cavity through the circulation air path set in the inner side wall of the cavity. The circulation air path is set along the inner side wall of the cavity and extends to the top of the cavity. In this way, the gaseous water mist and hydrogen peroxide can moisturize and sterilize the petri dishes on the turntable rack assembly 300 in the cavity, thereby ensuring a good environment in the cavity.

[0057] In one possible implementation, the inner wall of the receiving cavity is provided with a cell imaging device 500, which can observe and record the culture dish placed thereon, and the robotic arm assembly 400 can place the culture dish on the cell imaging device 500.

[0058] Understandably, to facilitate observation of the culture dishes without opening any doors, a cell imaging device 500 can be installed inside the containment cavity. The cell imaging device 500 is located in front of the robotic arm assembly 400. Whenever an experimenter needs to observe the culture dish, the robotic arm assembly 400 can transfer the culture dish from the turntable carrier assembly 300 to the platform of the cell imaging device 500 for imaging. The resulting image will be transmitted to an external computer. After the observation of the culture dish is completed, the robotic arm assembly 400 will return the culture dish to the turntable carrier assembly 300. With this setup, cells in the culture dish carrier can be observed and cell growth and experimental data recorded without opening any doors.

[0059] In one possible implementation, the robotic arm assembly 400 includes: a frame 410, a first guide rail 420, a tray assembly, and a drive motor 440; the frame 410 is installed into the cavity along a first direction; the first guide rail 420 is installed on the frame 410 along the first direction; the tray assembly is installed on the first guide rail 420 via a slide 430, and the tray assembly is rotatably connected to the slide 430 about the first direction for transferring petri dishes; the drive motor 440 is installed at the bottom of the frame 410, and its movable end is connected to a conveyor belt 450 for driving the slide 430 to move along the first guide rail 420.

[0060] Specifically, such as Figure 3 and Figure 4As shown, in this embodiment, the frame 410 is vertically arranged inside the receiving cavity, that is, extending along the first direction. Two parallel first guide rails 420 are laid on the side of the frame 410, and the first guide rails 420 also extend along the first direction. A slide 430 is installed on the first guide rails 420, and the slide 430 can move up and down along the first guide rails 420. In this embodiment, the movement of the slide 430 is achieved by a conveyor belt 450. A drive motor 440 is installed at the bottom of the frame 410, and a drive motor 440 is installed between the two first guide rails 420. A conveyor belt 450 is installed in the space, and the conveyor belt 450 is connected to the slide table 430. The lower end of the conveyor belt 450 is connected to the output shaft of the drive motor 440. That is, the rotation of the drive motor 440 drives the movement of the conveyor belt 450, which in turn drives the slide table 430 to move. It should be noted that in this embodiment, the tray assembly used to support the culture dishes is installed on the slide table 430 through an L-shaped connecting plate, thereby realizing the up and down movement of the tray assembly, so that the culture dishes at different heights on the turntable bracket assembly 300 can be lifted and transferred.

[0061] Furthermore, the tray assembly includes: a base 431 and a tray 432; the base 431 is horizontally mounted on the slide 430; the tray 432 is movably mounted on the base 431, and the tray 432 is used to support the petri dish and move it for transfer.

[0062] Understandably, when it is necessary to transfer the culture dish, the tray assembly is brought close to the culture dish, and then the tray 432 can be controlled to move along the base 431 to the bottom of the culture dish. Then the slide 430 moves upward, thereby lifting the culture dish from the turntable bracket assembly 300 to facilitate the subsequent transfer of the culture dish.

[0063] Furthermore, a first rotating motor 433 is provided on the lower side of the base 431. The first rotating motor 433 is used to drive the base 431 to rotate, so as to facilitate the transfer of the culture dish by the tray 432.

[0064] In this embodiment, to enable the rotation of the culture dish, a first rotation motor 433 is provided on the underside of the base 431 to control the overall rotation of the tray assembly. Specifically, after the tray assembly lifts the culture dish from the turntable support assembly 300 or the culture dish holder 130, it can be controlled to rotate to transfer the culture dish from the turntable support assembly 300 to the cell imaging device 500, or continue to rotate to transfer it to the culture dish holder 130 outside the cabinet 100. Of course, the first rotation motor 433 can rotate clockwise or counterclockwise to change the direction of transfer, and its specific rotation path is as follows. Figure 2 As shown in the image.

[0065] Once the tray assembly rotates to the desired position, the tray 432 extends along the length of the base 431, thereby moving the culture dish above the position of the turntable bracket assembly 300, the cell imaging device 500, or the culture dish bracket 130. Then, the slide 430 moves the tray assembly downwards, thus completing the transfer of the culture dish.

[0066] Furthermore, a second guide rail 434 is provided between the base 431 and the tray 432, and the tray 432 can move along the second guide rail 434; a second rotary motor 435 is also provided on the slide table 430, and a lever 436 is connected between the output shaft of the second rotary motor 435 and the tray 432, and the lever 436 can move along the second guide rail 434 under the drive of the second rotary motor 435.

[0067] In this embodiment, to facilitate the movement of the tray 432, a horizontal second guide rail 434 is laid in the middle of the base 431. At the same time, a second rotary motor 435 is installed on the slide table 430. The output shaft of the second rotary motor 435 also rotates around the first direction. A lever 436 is connected to the output shaft of the second rotary motor 435. The other end of the lever 436 is connected to the tray 432. In this way, when the second rotary motor 435 rotates, its output shaft will drive the tray 432 to move along the second guide rail 434 through the lever 436, so that the tray 432 can be inserted into or detached from the bottom of the culture dish.

[0068] In one possible implementation, a lifting module is provided on the side wall of the cabinet 100 near the transfer door 120. The lifting module includes a third guide rail installed on the side wall of the cabinet 100 and a movable slider that cooperates with the third guide rail. The transfer door 120 is fixedly connected to the movable slider. The lifting module also includes a lifting motor installed on the top of the cabinet 100 and a lifting screw threaded through the movable slider. The lifting screw is connected to the output shaft of the lifting motor.

[0069] In this embodiment, the lifting and lowering of the transfer door 120 is achieved by a lifting module installed on one side of the cabinet 100. This lifting module is a common moving module, which includes a third guide rail, a moving slider, a lifting screw, and a lifting motor. The lifting motor is installed on the top of the cabinet 100, and its output shaft is connected to the lifting screw. The lifting screw is threaded through the moving slider, and the moving slider is fitted to the third guide rail, which is also installed vertically. In this way, the lifting motor can control the up and down movement of the moving slider, and since the transfer door 120 is installed on the moving slider, the up and down movement of the transfer door 120 can be achieved.

[0070] In one possible implementation, the turntable tray assembly 300 includes a large, rotatable, circular turntable 310 and eight tray holders 320 detachably mounted on the circumference of the large turntable 310 for holding culture dishes.

[0071] Specifically, such as Figure 1 and Figure 2 As shown, a large circular turntable 310 is rotatably mounted at the bottom of the receiving cavity, and its rotation axis is vertical. On the upper side of the large turntable 310, eight tray racks 320 are evenly arranged. Each tray rack 320 has a multi-layer structure and can hold multiple layers of culture dishes. In this way, by controlling the rotation of the large turntable 310, the culture dishes to be transferred can be moved to the vicinity of the robotic arm assembly 400 for easy lifting.

[0072] In one possible implementation, the cabinet 100 includes a steel frame formed by welding several square steel pipes and sheet metal parts laid on the surface of the steel frame. Casters are also provided at the bottom of the cabinet 100.

[0073] Understandably, in this embodiment, the cabinet 100 is formed by welding several square steel pipes, and then several sheet metal parts are laid on its outer layer; at the same time, in order to facilitate the movement of the cabinet 100, casters with locking function are also provided at the bottom, so that the cabinet 100 can be moved to the expected position and then locked, thereby ensuring the stability of the cabinet 100.

[0074] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0075] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
