Description

Technical Field

[0001] This utility model relates to the technical field of petri dish filling, specifically to a lid opening mechanism and a filling mechanism. Background Technology

[0002] In the research and cultivation of microorganisms, it is usually necessary to place the microorganisms in petri dishes. The culture medium in the petri dishes can provide the necessary nutrients and environmental conditions for the growth, reproduction and metabolism of microorganisms, thereby promoting their rapid reproduction and metabolism.

[0003] Before adding culture medium to a petri dish or introducing microorganisms into the culture medium, it is necessary to use grippers to open the lid of the petri dish. Using grippers can prevent contamination of the microorganisms or culture medium inside the petri dish due to direct human contact, which would affect the research or cultivation of microorganisms.

[0004] However, when the lid and bottom shell of the petri dish are firmly sealed together, the bottom shell is easily lifted along with the lid when using the grippers to remove it, resulting in failure to open the petri dish and greatly affecting the success rate of microbial research and culture. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a cover opening mechanism is provided.

[0006] The lid-opening mechanism is used to open a vessel having a bottom shell and a lid that fits onto the bottom shell. The mechanism includes a worktable, a gripper assembly, and a pressing assembly. At least one support block is provided at the worktable. The gripper assembly is used to grip the bottom shell and / or the lid, and the bottom shell is driven onto the support block by the gripper assembly. The pressing assembly is configured to move toward or away from the bottom shell on the support block. Before the gripper assembly moves the lid away from the bottom shell, the pressing assembly moves toward the bottom shell on the support block until it abuts against the side wall of the bottom shell, pressing the bottom shell against the support block to limit the displacement of the bottom shell.

[0007] The opening mechanism of this invention, when it is necessary to open the lid of a vessel, allows the gripper assembly to hold the vessel and place the bottom shell of the vessel onto the support block. Then, the pressing assembly cooperates with the support block to create a clamping force on the bottom shell. By limiting the displacement of the bottom shell, the gripper assembly is prevented from lifting the bottom shell along with the lid, effectively ensuring the reliability and success rate of the opening mechanism. Furthermore, when applied to the research and cultivation of microorganisms, this opening mechanism can effectively improve the success rate of microbial research and cultivation.

[0008] For example, the outer contour of the support block is adapted to the inner contour of the bottom shell, and when the bottom shell is fitted onto the support block, at least a portion of the structure of the support block is embedded in the bottom shell.

[0009] For example, the pressing component includes a driving member and a pressing member. The pressing member is driven by the driving member to move toward or away from the bottom shell on the support block, so that the pressing member abuts against or disengages from the side wall of the bottom shell.

[0010] For example, the pressing member has at least two pressing parts arranged side by side, which abut against the side wall of their respective bottom shells under the action of the driving member.

[0011] According to another aspect of the present invention, a filling mechanism is also provided, including an installation platform, a liquid supply component, a filling component, and a cap opening mechanism as claimed in any one of the claims. The installation platform has a first region and a second region arranged in parallel. The liquid supply component, the filling component, the worktable, and the pressing component are all disposed on the first region, and the gripper component is disposed on the second region.

[0012] For example, the liquid supply assembly includes a liquid supply rack, a first liquid supply pipe, a second liquid supply pipe, and a pump body. The first liquid supply pipe is hung on the liquid supply rack, and its two ends are respectively connected to the liquid supply source and the inlet end of the pump body. The two ends of the second liquid supply pipe are respectively connected to the outlet end of the pump body and the filling assembly.

[0013] For example, the liquid supply frame includes a first frame and a second frame. The first frame is supported above the liquid supply source by the second frame, and the first frame is provided with a fixing clip that is detachably connected to the first liquid supply pipe.

[0014] For example, the filling assembly includes a filling needle, a support block located below the filling needle, and the filling needle is connected to the outlet end of the pump body via a second supply pipe.

[0015] For example, the filling mechanism also includes a mounting component, the pump body is mounted above the mounting platform via the mounting component, a receiving cavity is formed within the mounting component, and a power supply component that provides electrical power to the pump body is located within the receiving cavity.

[0016] For example, the filling mechanism also includes a plurality of limiting plates disposed on the mounting component, the plurality of limiting plates enclosing a storage cap space, and the cap being clamped and transferred into the storage cap space by a gripper assembly.

[0017] For example, the filling mechanism further includes a flipping component disposed on the mounting member, the flipping component having a first state that locks the cap to the bottom shell and a second state that unlocks the cap to the bottom shell, the flipping component driving the container to rotate circumferentially in the first state.

[0018] For example, the flipping assembly includes a limiting member and a flipping platform for holding the bottom shell, the limiting member being close to the flipping platform to lock the cover to the bottom shell, and the limiting member being far from the flipping platform to unlock the cover from the bottom shell.

[0019] For example, the filling mechanism also includes a material rack and a cooling rack, both disposed on the second region, and located on opposite sides of the gripper assembly.

[0020] For example, a liquid injection port is formed on the cooling rack, and a liquid injection chamber communicating with the liquid injection port is formed inside the cooling rack.

[0029] To make the objectives, technical solutions, and advantages of this utility model more apparent, exemplary embodiments according to this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein. Based on the embodiments of this utility model described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this utility model.

[0030] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0031] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0032] One embodiment of this utility model provides a lid-opening mechanism. This mechanism can limit the displacement of the bottom shell 11 to prevent the gripper assembly 3 from lifting the bottom shell 11 along with the lid, effectively ensuring the reliability and success rate of the lid-opening mechanism. The following will describe in detail one lid-opening mechanism according to an embodiment of this utility model with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2As shown, the opening mechanism is used to open the lid of the vessel 1, which has a bottom shell 11 and a lid that fits onto the bottom shell 11. The opening mechanism includes a worktable, a gripper assembly 3, and a pressing assembly 4. At least one support block 2 is provided at the worktable. The gripper assembly 3 is used to grip the bottom shell 11 and / or the lid, and the bottom shell 11 is driven onto the support block 2 by the gripper assembly 3. The pressing assembly 4 is configured to move toward or away from the bottom shell 11 on the support block 2. Before the gripper assembly 3 moves the lid away from the bottom shell 11, the pressing assembly 4 moves toward the bottom shell 11 on the support block 2 until it abuts against the side wall of the bottom shell 11, pressing the bottom shell 11 against the support block 2 to limit the displacement of the bottom shell 11.

[0034] The number of support blocks 2 can be multiple, and multiple support blocks 2 are spaced apart on the worktable, so that multiple containers 1 can be opened at the same time, effectively improving the opening efficiency of the opening mechanism.

[0035] The aforementioned gripper assembly 3 can be mounted on a worktable. Specifically, the gripper assembly 3 can be a six-axis robotic arm, which can flexibly grip the bottom shell 11 and / or lid of the vessel 1 to hold and transfer the vessel 1 onto the support block 2. After the vessel 1 is placed on the support block 2, the pressing assembly 4 can move towards the bottom shell 11 to engage with the outer wall of the support block 2 to grip the bottom shell 11 of the vessel 1. At this time, when gripping the lid of the vessel 1, the gripper assembly 3 can avoid lifting the bottom shell 11 as well. After opening the lid of the vessel 1, the pressing assembly 4 can move away from the bottom shell 11 to release the bottom shell 11 and facilitate subsequent operations.

[0036] The opening mechanism of this invention, when it is necessary to open the lid of the vessel 1, allows the gripper assembly 3 to hold the vessel 1 and place the bottom shell 11 of the vessel 1 onto the support block 2. Then, the pressing assembly 4 cooperates with the support block 2 to form a clamping force on the bottom shell 11. By limiting the displacement of the bottom shell 11, the gripper assembly 3 can prevent the bottom shell 11 from being lifted along with the lid, effectively ensuring the reliability and success rate of the opening mechanism. Furthermore, when applied to the research and cultivation of microorganisms, this opening mechanism can effectively improve the success rate of microbial research and cultivation.

[0037] In some embodiments, such as Figure 2 As shown, the outer contour of the support block 2 is adapted to the inner contour of the bottom shell 11. When the bottom shell 11 is fitted onto the support block 2, at least a portion of the structure of the support block 2 is embedded in the bottom shell 11.

[0038] The lower edge of the bottom shell 11 can extend away from the lid to form an annular boss 12. The contour of the inner cavity of the annular boss 12 can be constructed as the inner contour of the bottom shell 11. When the bottom shell 11 of the vessel 1 is fitted onto the support block 2, the support block 2 can be embedded in the inner cavity of the annular boss 12 to firmly and stably fix the vessel 1 onto the support block 2.

[0039] In the above embodiment, when the bottom shell 11 of the vessel 1 is fitted onto the support block 2, at least a portion of the support block 2 can be embedded in the bottom shell 11, so that the outer side walls of the pressing component 4 and the support block 2 can respectively form surface contact with the bottom shell 11, effectively improving the firmness and stability of the pressing component 4, thereby ensuring that when the gripper component 3 clamps the cover, the bottom shell 11 can be firmly fixed on the support block 2.

[0040] In some embodiments, such as Figure 2 As shown, the pressing component 4 includes a driving member and a pressing member 41. The pressing member 41 is driven by the driving member to move towards or away from the bottom shell 11 on the support block 2, so that the pressing member 41 abuts against or disengages from the side wall of the bottom shell 11.

[0041] The aforementioned driving component can be connected to the pressing component 41 to drive the pressing component 41 to move towards or away from the bottom shell 11 on the support block 2. The driving component can be a cylinder or other device that can drive the pressing component 41 to move. This application does not specifically limit the type of driving component.

[0042] In the above embodiments, the pressing member 41 can be driven by the driving member to move towards or away from the bottom shell 11, so as to flexibly adjust the relative positional relationship between the pressing member 41 and the bottom shell 11, effectively improving the flexibility and convenience of using the pressing component 4.

[0043] In some embodiments, such as Figure 2 As shown, the pressing member 41 has at least two pressing parts 411 arranged in parallel, and the pressing parts 411 abut against the side wall of their respective bottom shell 11 under the drive of the driving member.

[0044] The end of the pressing member 41 near the vessel 1 can be bent upward or downward to form a pressing part 411. The pressing part 411 can be plate-shaped, and the plate-shaped pressing part 411 can form a surface contact when it abuts against the bottom shell 11.

[0045] When there are two pressing parts 411 on the pressing member 41, the shape of the pressing member 41 can be Y-shaped. The two pressing parts 411 can be formed at the two branch ends of the Y-shaped pressing member 41 respectively. In this way, the bottom shells 11 of the two vessels 1 can be limited by one pressing member 41 at the same time.

[0046] In the above embodiments, the pressing member 41 may have at least two pressing parts 411 arranged in parallel. When the driving member drives the pressing member 41 to move towards the bottom shell 11, the multiple pressing parts 411 on the pressing member 41 can act on the corresponding bottom shell 11 at the same time, thereby pressing a batch of bottom shells 11 at the same time, effectively improving the driving efficiency of the driving member and the opening efficiency of the opening mechanism.

[0047] According to another aspect of this utility model, such as Figure 1 As shown, a filling mechanism is also provided, including an installation platform 5, a liquid supply component 6, a filling component 7, and a cap opening mechanism as claimed in any one of the claims. The installation platform 5 has a first region 51 and a second region 52 arranged in parallel. The liquid supply component 6, the filling component 7, the worktable, and the pressing component 4 are all disposed on the first region 51, and the gripper component 3 is disposed on the second region 52.

[0048] When the filling mechanism is used in microbial research and culture, the liquid supply component 6 can heat the culture medium to liquefy its components. The filling component 7 can drip the liquid culture medium into the vessel 1 after the lid of the vessel 1 is opened by the lid opening mechanism.

[0049] The aforementioned liquid supply component 6 can be located beside the cap opening mechanism. Specifically, multiple positioning posts 53 can be provided on the first area 51 of the mounting platform 5. The multiple positioning posts 53 can enclose and form a positioning space that matches the outer contour of the bottom of the liquid supply component 6. In this way, when the liquid supply component 6 is placed in the aforementioned positioning space, displacement of the liquid supply component 6 can be effectively avoided.

[0050] The filling component 7 can be positioned above the capping mechanism, so that when the capping mechanism opens the cap of the container 1, the filling component 7 can directly drip the culture medium, reducing the movement path of the filling component 7.

[0051] like Figure 4 As shown, the filling mechanism may also include a positive pressure laminar flow hood 130 installed above the installation platform 5. The positive pressure laminar flow hood 130 can filter the air inside the filling mechanism to ensure the cleanliness of the air inside the filling mechanism.

[0052] In this invention, the liquid supply component 6, the filling component 7, the worktable, and the pressing component 4 can all be set on the first area 51, while the gripper component 3 can be set on the second area 52. By setting the gripper component 3 on the side of each component, the gripping operation can be completed conveniently and flexibly at the side of the workstation. While optimizing the layout of the filling mechanism, the filling efficiency of the filling mechanism is also effectively improved.

[0053] In some embodiments, such as Figures 1 to 3As shown, the liquid supply assembly 6 includes a liquid supply rack 61, a first liquid supply pipe (not shown in the drawing), a second liquid supply pipe (not shown in the drawing), and a pump body 62. The first liquid supply pipe is hung on the liquid supply rack 61, and both ends of the first liquid supply pipe are connected to the liquid supply source and the inlet end of the pump body 62, respectively. Both ends of the second liquid supply pipe are connected to the outlet end of the pump body 62 and the filling assembly 7, respectively.

[0054] The first supply pipe connects the liquid source to the pump body 62, and the second supply pipe connects the pump body 62 to the filling assembly 7. These two supply pipes ensure a continuous flow path between the liquid source and the filling assembly 7, and the pump body 62 can extract liquid culture medium, thus ensuring the filling efficiency of the filling assembly 7. Specifically, the first and second supply pipes can be flexible hoses, and the pump body 62 can be a peristaltic pump.

[0055] The number of pump bodies 62 can correspond to the number of liquid supply components 6, so that each liquid supply component 6 can have a corresponding pump body 62, such as... Figure 3 As shown, the number of pump bodies 62 can be two, and the two pump bodies 62 can be connected with... Figure 1 The two liquid supply components 6 in the middle are in one-to-one correspondence.

[0056] In the above embodiments, the first liquid supply pipe and the second liquid supply pipe can be mounted above the installation platform 5 via the liquid supply rack 61. This ensures that the liquid culture medium in the liquid supply source can flow to the filling component 7, while also preventing the first liquid supply pipe and the second liquid supply pipe from being directly laid on the installation platform 5, which would cause interference and entanglement between the first liquid supply pipe and the second liquid supply pipe. This effectively improves the neatness and aesthetics of the filling mechanism, reduces safety hazards, and ensures the stable and efficient operation of the filling mechanism.

[0057] In some embodiments, such as Figures 1 to 3 As shown, the liquid supply rack 61 includes a first frame 611 and a second frame 613. The first frame 611 is supported above the liquid supply source by the second frame 613. The first frame 611 is provided with a fixing clip 612 that is detachably connected to the first liquid supply pipe.

[0058] The second frame 613 can be vertically mounted on the installation platform 5, and the first frame 611 can be connected to the second frame 613 so that it can be mounted above the liquid supply source via the second frame 613.

[0059] The number of the aforementioned fixing clips 612 can be multiple, and the multiple fixing clips 612 can be spaced apart along the length direction of the first frame 611. The fixing frame can be used to clamp the first liquid supply pipe to ensure that the first liquid supply pipe can be installed above the liquid supply source.

[0060] In the above embodiment, the first frame 611 may be equipped with a fixing clip 612 that is detachably connected to the first liquid supply tube. This eliminates the need for complex tools and cumbersome procedures; the first liquid supply tube can be quickly fixed simply by clamping it with the fixing clip. Furthermore, when the first liquid supply tube is damaged or blocked, the detachable fixing clip 612 can easily remove the first liquid supply tube from the first frame 611, effectively ensuring the efficiency of inspection, repair, or replacement. In addition, the fixing clip 612 is adaptable to various specifications of first liquid supply tubes, enabling the fixing of different specifications of first liquid supply tubes and effectively expanding the applicability of the liquid supply system.

[0061] In some embodiments, such as Figures 1 to 3 As shown, the filling assembly 7 includes a filling needle 71, a support block 2 located below the filling needle 71, and the filling needle 71 is connected to the outlet end of the pump body 62 through a second liquid supply pipe.

[0062] The filling assembly 7 may further include a drive mechanism connected to the filling needle 71. This drive mechanism can move the filling needle 71 along the X, Y, and Z axes of a Cartesian coordinate system. Specifically, when the filling needle 71 moves along the X and Y axes, it can accurately move above the container 1. When the filling needle 71 moves along the Z axis, it can approach the bottom shell 11 of the container 1, ensuring high-speed dripping while avoiding the generation of air bubbles, effectively guaranteeing the filling effect of the filling assembly 7.

[0063] The aforementioned drive mechanism may employ various types of drive mechanisms known in the art or that may emerge in the future, including but not limited to motor drive mechanisms, cylinder drive mechanisms or electric cylinder drive mechanisms, and this application does not specifically limit them.

[0064] When the drive mechanism moves the filling needle 71, the filling needle 71 will only pull the second liquid supply tube synchronously, while the first liquid supply tube located at the inlet end of the pump body 62 can always remain stationary, thus ensuring the tightness and firmness of the connection between the first liquid supply tube and the pump body 62.

[0065] In the above embodiment, the liquid culture medium can flow to the filling needle 71 through the second supply tube, and then drip into the vessel 1 through the filling needle 71. The filling needle 71 can precisely control the amount of culture medium dripped, thereby ensuring the success rate of microbial culture and research.

[0066] In some embodiments, such as Figures 1 to 3 As shown, the filling mechanism also includes a mounting component 8. The pump body 62 is mounted on the mounting platform 5 via the mounting component 8. A receiving cavity is formed inside the mounting component 8, and a power supply component that provides power to the pump body 62 is located inside the receiving cavity.

[0067] The aforementioned mounting component 8 can be mounted on the mounting platform 5 via the support arm 81. The pump body 62 can be mounted on the outer wall of the mounting component 8. The mounting component 8 can have a through hole that communicates with the accommodating cavity. The power supply component located in the accommodating cavity can pass through the through hole and connect to the pump body 62.

[0068] The aforementioned power supply components can specifically refer to wires or cables, etc., and this application does not make any specific limitation in this regard.

[0069] In the above embodiment, the pump body 62 can be mounted above the mounting platform 5 via the mounting bracket 8, thus avoiding occupying additional space on the mounting platform 5. Furthermore, the power supply unit providing power to the pump body 62 can be concealed within the receiving cavity, further enhancing the neatness and aesthetics of the filling mechanism.

[0070] In some embodiments, such as Figure 2 As shown, the filling mechanism also includes multiple limiting plates 9 disposed on the mounting component 8. The multiple limiting plates 9 enclose a cap storage space 91, and the cap is clamped and transferred into the cap storage space 91 by the gripper assembly 3.

[0071] The multiple limiting plates 9 may include at least a base plate and side plates disposed on the base plate, and the three side plates may cooperate with the outer side wall of the mounting member 8 to form the aforementioned storage cover space 91.

[0072] In the above embodiment, when the gripper assembly 3 holds the lid to open the container 1, the gripper assembly 3 can transfer the lid and temporarily store it in the lid storage space 91, so that the gripper assembly 3 can continue to perform other operations, effectively improving the utilization rate of the gripper assembly 3.

[0073] In some embodiments, such as Figure 2 As shown, the filling mechanism also includes a flipping component 10 disposed on the mounting component 8. The flipping component 10 has a first state that locks the cap to the bottom shell 11 and a second state that unlocks the cap to the bottom shell 11. In the first state, the flipping component 10 drives the container 1 to rotate circumferentially.

[0074] In its first state, the flipping assembly 10 can apply forces to the lid and the bottom shell 11 respectively, so that the two are securely fastened together. In its second state, the flipping assembly 10 can remove the aforementioned forces, and the lid can be easily opened by releasing the lid and the bottom shell 11. The flipping assembly 10 can be connected to a rotating mechanism 140, which can drive the flipping assembly 10 to rotate, thereby causing the vessel 1 to rotate circumferentially.

[0075] After liquid culture medium is poured into the bottom shell 11 of the vessel 1, the culture medium can slowly cool and solidify into a solid state. At this time, the gripper assembly 3 can reattach the lid of the vessel 1 to the bottom shell 11 and place the vessel 1 at the flipping assembly 10. The flipping assembly 10 can put the vessel 1 in the first state and drive the vessel 1 to rotate 30 degrees, 90 degrees, 180 degrees or 360 degrees in the circumference, so that the gripper assembly 3 can perform subsequent operation steps.

[0076] In the above embodiments, the flipping component 10 can switch between a first state and a second state. In the first state, the flipping component 10 can drive the container 1 to rotate circumferentially so that the container 1 can have different rotation angles, thereby facilitating the filling operation of the filling mechanism and effectively improving the practicality and flexibility of the filling mechanism.

[0077] In some embodiments, such as Figure 2 As shown, the flipping assembly 10 includes a limiting member 101 and a flipping platform 102 for holding the bottom shell 11. The limiting member 101 is close to the flipping platform 102 to lock the cover to the bottom shell 11, and the limiting member 101 is far away from the flipping platform 102 to unlock the cover from the bottom shell 11.

[0078] The aforementioned flipping platform 102 can be used to support the bottom shell 11 of the vessel 1, and the limiting member 101 can be disposed above the flipping platform 102. Figure 2 As shown, a positioning boss 1021 can be formed on the upper edge of the top corner of the flipping platform 102. When the bottom shell 11 is placed on the flipping platform 102, the positioning boss 1021 can limit the displacement of the bottom shell 11 on the flipping platform 102.

[0079] The aforementioned limiting member 101 can be plate-shaped. The plate-shaped limiting member 101 forms a surface contact with the cover, effectively ensuring the stability of the contact between the two.

[0080] The limiting member 101 can move towards the flipping platform 102 to cooperate with the flipping platform 102 to clamp the lid and bottom shell 11 of the vessel 1. At this time, the flipping assembly 10 can be in the first state. The limiting member 101 can move away from the flipping platform 102 to release the lid and bottom shell 11 of the vessel 1. At this time, the flipping assembly 10 can be in the second state.

[0081] In the above embodiments, the cooperation between the limiting member 101 and the flipping platform 102 not only allows the flipping component 10 to switch flexibly between the first state and the second state, but also simplifies the structure of the flipping component 10 and reduces the manufacturing difficulty and failure rate of the flipping component 10.

[0082] In some embodiments, such as Figure 1As shown, the filling mechanism also includes a material rack 110 and a cooling rack 120, both of which are disposed on the second region 52 and are located on opposite sides of the gripper assembly 3.

[0083] The aforementioned material rack 110 can vertically stack multiple containers 1 without culture medium added, and the gripper assembly 3 can grip the containers 1 in the material rack 110 sequentially from top to bottom. The cooling rack 120 can be provided with multiple cooling positions. The gripper assembly 3 can place the containers 1 with culture medium added into the cooling positions on the cooling rack 120 to reduce the temperature of the culture medium inside the containers 1 through natural heat dissipation. Because the containers 1 are placed horizontally during the cooling process, the culture medium in the containers 1 can dissipate heat evenly, effectively ensuring the flatness of the culture medium after cooling.

[0084] The aforementioned material rack 110 and cooling rack 120 can be set on the second area 52, so as to have a certain distance from the first area 51 where the liquid supply component 6, filling component 7 and cap opening mechanism are located. This can optimize the layout of the filling mechanism and avoid interference between the gripper component 3 in picking up and placing the container 1 and in holding the container 1 to open the cap.

[0085] Multiple positioning posts 53 can also be provided on the first area 51 of the installation platform 5. The multiple positioning posts 53 can enclose and form a positioning space that matches the outer contour of the bottom of the material rack 110. In this way, when the material rack 110 is placed in the positioning space, displacement of the material rack 110 can be effectively avoided.

[0086] like Figure 1 As shown, the side wall of the aforementioned material rack 110 can be vertically extended. This not only facilitates the operation of the gripper assembly 3 in holding the container 1, but also allows the user to easily observe and replenish the container 1 when it is missing from the material rack 110. The aforementioned material rack 110 can be equipped with a handle 1101, which the user can pull to easily pick up and put down the material rack 110.

[0087] In the above embodiments, the material rack 110 can be used to store the vessel 1 without culture medium, while the cooling rack 120 can be used to collect the vessel 1 with culture medium. By configuring the material rack 110 and the cooling rack 120, the practicality of the filling mechanism can be further improved. Furthermore, the material rack 110 and the cooling rack 120 can be located on opposite sides of the gripper assembly 3, allowing the gripper assembly 3 to perform precise operations in the corresponding areas according to different operating steps. This effectively improves the layout rationality of the filling mechanism, while also increasing filling efficiency and space utilization.

[0088] In some embodiments, a liquid injection port (not shown) is formed on the cooling rack 120, and a liquid injection chamber communicating with the liquid injection port is formed inside the cooling rack 120.

[0089] In the above embodiments, clean water or coolant can flow into the injection chamber through the injection port on the cooling rack 120 to absorb the heat in the culture medium, thereby quickly reducing the temperature of the culture medium and further improving the filling efficiency of the filling mechanism.
