Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a laboratory material transfer device. Background Technology

[0002] Maintaining a sterile environment is a key factor in ensuring experimental success in aseptic biological laboratories. Traditional material transfer methods rely primarily on manual operation of transfer windows, which has several drawbacks. First, frequent personnel entry and exit increase the risk of bacterial and contaminant intrusion; even with automatic sterilization functions, the risk of contamination from human factors cannot be completely eliminated. Second, manual operation is inefficient, failing to meet the demands of high-throughput experiments, and carries the potential for human error, such as improper operation leading to material contamination or incorrect transfer.

[0003] In existing technologies, pass-through windows typically use ultraviolet sterilization or chemical disinfection to disinfect the surface of materials, but these methods cannot solve the problem of air pollution caused by personnel entering and exiting. Furthermore, traditional pass-through windows lack automation capabilities, and the material transfer process still requires manual intervention, failing to achieve truly unmanned operation. Therefore, we provide a laboratory material transfer device to address these issues. Utility Model Content

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0040] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figure 1 — Figure 10 The example shown.

[0042] This application provides a laboratory material transfer device, which includes a machine base 100. The machine base 100 has a first hopper 200 and a second hopper 300. Both the first hopper 200 and the second hopper 300 have a first opening and a second opening. A first closing door 400 is provided at the first opening, and a second closing door is provided at the second opening. A first conveying device for transferring and conveying materials is provided in the first hopper 200, and a second conveying device for transferring and conveying materials is provided in the second hopper 300.

[0043] See Figures 1 to 3 As shown, in this embodiment, the first hopper 200 has a first conveying device, the second hopper 300 has a second conveying device, and an AGV trolley is provided on one side of the machine 100 (inside the laboratory). A robotic arm is installed on the AGV trolley. The robotic arm is moved by the AGV trolley, so that the material picked up by the robotic arm is placed in a preset position.

[0044] Furthermore, the first hopper 200 is used to transport materials to the laboratory, and the second hopper 300 is used to collect materials that have been used from the laboratory. It can be understood that the first opening is an opening facing the direction of the laboratory robotic arm, and the second opening is an opening away from the direction of the laboratory robotic arm. The first sealing door 400 is used to open and close the first opening, and the second sealing door is used to open or close the second opening. The second opening of the first hopper 200 is used to place new unused materials into its interior to provide unused materials for the first conveying device. The second opening of the second hopper 300 is used to remove old materials (used materials) from its interior. That is, the first hopper 200 contains unused materials, while the second hopper 300 stores used materials.

[0045] In this embodiment, the second opening of the first hopper 200 is opened through the second sealing door, and new material is manually placed onto the first conveying device. Then, the second sealing door closes the second opening of the first hopper 200. When the required material is needed, the first sealing door 400 opens the first opening of the first hopper 200, and the AGV trolley moves the robotic arm to the position of the first opening of the first hopper 200. The first conveying device transports the required material to the position of the first opening of the first hopper 200, the robotic arm takes the material out of the first opening of the first hopper 200, and the AGV trolley transports the material gripped by the robotic arm to a predetermined position. Next, the AGV trolley and the robotic arm cooperate... The used material is conveyed to the first opening of the second silo 300. At this time, the first closing door 400 opens the first opening of the second silo 300, and the robotic arm places the used material into the second conveying device. After placement, the second conveying device conveys the used material to the second opening of the second silo 300. Then, the second closing door opens the second opening of the second silo 300, and the used material is manually removed from the second opening of the second silo 300. Next, the second closing door closes the second opening of the second silo 300. It is possible that the first opening and the second opening of the first silo 200 and the second silo 300 cannot be opened at the same time; only one opening can be opened at a time.

[0046] This application achieves automated material transfer in a sterile environment by setting up a first hopper 200 and a second hopper 300, avoiding the risk of contamination caused by manual operation. Furthermore, the cooperation between AGV carts and robotic arms improves the efficiency of material transfer and reduces the possibility of human error.

[0047] In this embodiment, the machine 100 is also equipped with a manual compartment 900. The manual compartment 900 also has a first opening and a second opening. A first closing door 400 is provided at the first opening, and a second closing door is provided at the second opening. The manual compartment 900 is also equipped with a lighting lamp and a sterilizing lamp. Special items such as books, tweezers, and pens are passed through the manual compartment 900. The items passing through the manual compartment 900 are sterilized and disinfected. It is understood that in order to ensure the isolation of the laboratory from the external environment, the first opening and the second opening of the manual compartment 900 cannot be opened at the same time.

[0048] In this embodiment, the materials are pipette tips, cell flasks, and a dish (six-well dish). Of course, other material transfer devices can be customized as needed, which are not limited here.

[0049] like Figure 11As shown, in this embodiment, both the first hopper 200 and the second hopper 300 have an inner liner (101). The inner liner (101) has a first opening and a second opening. A lighting lamp (102) and a sterilizing lamp (103) are installed on the inner wall of the inner liner (101). The first sealing door (400) opens or closes the first opening of the inner liner (101), and the second sealing door opens or closes the second opening of the inner liner (101). It can be understood that in order to ensure a sterile environment, any items entering the first hopper 200 and the second hopper 300 need to be sterilized. Sterilization treatment requires sterilizing and disinfecting both new materials placed in the first silo 200 and used materials. To achieve this, sterilization lamps are installed inside the first silo 200 and the second silo 300. Specifically, the sterilization lamps can be ultraviolet lamps, which can be installed on the inner top walls of the first silo 200 and the second silo 300 to irradiate from top to bottom. In another embodiment, multiple ultraviolet lamps can be installed, or they can be installed in other locations, such as on the side arms of the first silo 200 and the second silo 300.

[0050] It is understood that both the first and second conveying devices are located within the inner liner 101 of the first hopper 200 and the second hopper 300. The inner liner 101 separates the first and second conveying devices from the outside, preventing foreign objects from entering and contaminating the items being conveyed. Combined with the first sealing door 400 closing the first opening and the second sealing door closing the second opening of the inner liner 101, the items conveyed by the two conveying devices are completely isolated from the external environment. When both openings are closed, the interior of the inner liner 101 is a completely isolated space, and the germicidal lamp 102 sterilizes its interior, maintaining a sterile environment inside the inner liner 101. It should be noted that the manual storage compartment 900 also has an inner liner 101.

[0051] In order to facilitate the observation of the conveying of materials in the first hopper 200 and the second hopper 300, lighting lamps are installed in both the first hopper 200 and the second hopper 300 to provide the light required for observation.

[0052] For example, lighting fixtures can use LED lights or fluorescent lights, which are characterized by high brightness, low energy consumption and long life, and can provide stable lighting effects.

[0053] The first closed door 400 includes two side plates 410, a door panel 420, a linear drive 430, and a grating 440. The side plates 410 are provided with guide rails 411 on their sides. The door panel 420 is located between the two side plates 410. Guide wheels 421 are provided on both sides of the door panel 420. The guide wheels 421 extend at least partially into the guide rails 411. The linear drive 430 is fixedly installed on the machine base 100. The telescopic end of the linear drive 430 is connected to the door panel 420. The grating 440 is fixedly installed on one side of the two side plates 410 that are close to each other.

[0054] In another embodiment, the structure of the second closed door can be the same as or different from that of the first closed door 400. For example, the structure of the second closed door can be a manual opening or closing method. Here, the structure of the second closed door can be the same as that of the first closed door 400.

[0055] See Figure 4 As shown, when it is necessary to close the first opening of the first hopper 200 and the second hopper 300, the door panel 420 is driven to move downward by the linear drive 430. In order to ensure the stable movement of the door panel 420, the trajectory required for the movement of the door panel 420 is opened on the side plate 410, and guide wheels 421 are installed on both sides of the door panel 420 so that the guide wheels 421 extend into the guide rail 411. Thus, when the linear drive 430 drives the door panel 420 to move, the guide wheels 421 and the guide rail 411 cooperate to move downward stably and prevent the trajectory from changing.

[0056] A linear drive unit 430 is fixedly mounted on the machine base 100. The telescopic end of the linear drive unit 430 is connected to the door panel 420, and the automatic opening and closing of the door panel 420 is achieved through the telescopic movement of the linear drive unit 430. A grating 440 is fixedly mounted on one side of the two side panels 410 that are close to each other, so as to detect when the robot arm enters the first hopper 200 or the second hopper 300. When the grating 440 detects the robot arm or a foreign object passing through the first hopper 200, the linear drive unit 430 stops driving the door panel 420 to move, so as to prevent the door panel 420 from damaging the robot arm or itself, and to prevent motion interference.

[0057] In this embodiment, the guide rail 411 is a groove, and the guide wheel 421 can be made of wear-resistant material to ensure smooth movement within the guide rail 411. The linear drive component 430 can take various forms such as an electric actuator or a pneumatic actuator, and its telescopic end can be connected to the door panel 420 by bolts, welding, or other methods. The grating 440 can take various forms such as an infrared grating 440 or a laser grating 440, and its installation position can be adjusted according to the specific layout of the laboratory.

[0058] Both the first and second conveying devices include a cell bottle conveying device 500. The cell bottle conveying device 500 includes a linear drive module 510, a driven plate 520, and a carrier plate 530. The driven plate 520 is fixedly installed on the drive end of the linear drive module 510. The carrier plate 530 is disposed on the driven plate 520 and has a plurality of placement slots 531.

[0059] Since the cell flask delivery devices 500 of the first and second delivery devices are the same, their working principles are the same. Here, we will take the first delivery device as an example to illustrate how it provides cell flasks to the laboratory.

[0060] Please see Figure 4 and Figure 5 As shown, when the laboratory needs cell flasks, the linear drive module 510 drives the driven plate 520 to move. Since each cell flask is located in each placement slot 531 on the carrier plate 530, the carrier plate 530 is placed on the driven plate 520. Therefore, each cell flask on the carrier plate 530 is driven by the linear drive module 510 to move along a preset direction.

[0061] It should be noted that the cell culture flask can also be other items, such as petri dishes, test tubes, etc. Understandably, the shape of the placement tank 531 also needs to be changed accordingly depending on the different items.

[0062] For example, the linear drive module 510 can use components that can realize linear drive, such as electric linear actuators, pneumatic linear actuators, motor lead screw linear modules, linear motor modules, and motor synchronous belt linear modules. No specific limitation is made here.

[0063] The driven plate 520 has a positioning groove 521 on its upper surface that is adapted to the carrier plate 530, and the carrier plate 530 is disposed in the positioning groove 521; handles 540 are provided on both sides of the carrier plate 530.

[0064] Please continue reading. Figure 4 and Figure 5 As shown, the upper surface of the driven plate 520 has a positioning groove 521 adapted to the carrier plate 530. The size and shape of the positioning groove 521 match the bottom of the carrier plate 530, allowing the carrier plate 530 to be accurately embedded in the positioning groove 521. The positioning groove 521 can be rectangular, circular, or other geometric shapes to accommodate carrier plates 530 of different shapes. The depth of the positioning groove 521 should be appropriate to ensure that the carrier plate 530 can be placed stably in the positioning groove 521 without wobbling. Furthermore, the inner wall of the positioning groove 521 can be provided with a cushioning material, such as a rubber pad, to reduce vibration and impact when the carrier plate 530 is placed.

[0065] By setting a positioning groove 521 on the driven plate 520 that is compatible with the carrier plate 530, the stable positioning of the carrier plate 530 on the driven plate 520 is ensured, avoiding the carrier plate 530 from shifting or sliding during the conveying process, thus improving the accuracy and reliability of material transfer. Furthermore, the positioning between the carrier plate 530 and the positioning groove 521 makes it easier to separate the carrier plate 530 from the positioning groove 521. Simply lifting the carrier plate 530 is sufficient to separate the carrier plate 530 from the positioning groove 521, facilitating the loading and unloading of new and old materials.

[0066] In this embodiment, handles 540 are provided on both sides of the carrier plate 530, making the carrier plate 530 easier to operate and handle during transportation. The handles 540 can improve the operator's control over the carrier plate 530, reducing inconvenience and errors during transportation. The handles 540 can be implemented in various ways. For example, as a preferred embodiment, the handles 540 can be designed to be foldable, so that they can be folded away when not in use, saving space. Furthermore, the material of the handles 540 can be a material with anti-slip properties, such as rubber or silicone, to increase the safety and comfort of operation. In addition, the installation position and angle of the handles 540 can also be adjusted according to actual needs to adapt to the usage habits of different operators.

[0067] Both the first and second conveying devices include a gun head conveying device 600. The gun head conveying device 600 includes a mounting frame 610, on which a conveyor belt 620 is mounted. The power input end of the conveyor belt 620 is connected to a rotary drive component 630. A positioning sensor 640 is mounted on the end frame of the mounting frame 610. Guide plates 650 located on both sides of the conveyor belt 620 are mounted on the frame of the mounting frame 610.

[0068] See Figure 7 As shown, when pipette tips are needed inside the laboratory, the rotary drive 630 drives the conveyor belt 620 to rotate. The conveyor belt 620 moves the box containing the pipette tips to the predetermined position. When the positioning sensor 640 detects the box containing the pipette tips, it can determine that the box has reached the predetermined position, and the rotary drive 630 stops driving the conveyor belt 620 to rotate.

[0069] To prevent the box from shifting position during movement, guide plates 650 are installed on both sides of the conveyor belt 620 to guide it.

[0070] For example, the rotary drive 630 can be a servo motor or a stepper motor to provide precise power control. The positioning sensor 640 can be a photoelectric sensor or a laser sensor to ensure high-precision positioning.

[0071] The first conveying device includes a vessel feeding conveying device 700, which includes a first conveying line 710. A first fixing frame 720 is provided at one end of the first conveying line 710. The first fixing frame 720 has a first clearance groove 721. A first shell 730 is provided on the first fixing frame 720. The first shell 730 has a first receiving cavity inside, which communicates with the first clearance groove 721. A through groove 731 is provided on the bottom edge of the first shell 730, which communicates with the first receiving cavity. A first lifting member 740 is provided below the first fixing frame 720. A clamping cylinder 750 is fixedly installed on the first fixing frame 720, and a clamping block 751 is installed at the clamping end of the clamping cylinder 750.

[0072] See Figure 2 and Figure 8 As shown, it should be noted that multiple vessels are stacked sequentially from top to bottom in the first receiving cavity of the first shell 730. If there are no other obstructions, they will fall downwards under gravity. In the initial state, the first lifting member 740 lifts upwards, causing the second to last vessel to be lifted to the position of the through groove 731. Then, the clamping cylinder 750 drives the clamping block 751 to move. The clamping block 751 passes through the through groove 731 to the position of the second to last vessel and clamps it. At this time, the second to last vessel and the vessels above it will not fall downwards. Next, the lifting end of the first lifting member 740 moves downwards to return to the initial position (located below the conveying surface of the first conveyor line (710)). Since the last container is no longer lifted by the first lifting member 740, it will fall onto the first conveyor line 710. The first conveyor line 710 will transport the container to the first opening position of the first hopper 200, where it will wait to be gripped and transferred by the robotic arm. When a new container is needed again, the gripping cylinder 750 will move the gripping block 751 to release the gripping state. Then, with the cooperation of the first lifting member 740 and the gripping cylinder 750, the above operation will be repeated so that the last container is transported onto the first conveyor line 710 and then transported again to the first opening position by the first conveyor line 710 to wait to be moved and transferred.

[0073] For example, the first conveyor line 710 can be a synchronous belt conveyor, and the corresponding motor drives the rotation. The first lifting member 740 can be composed of a lifting plate and a cylinder, that is, the cylinder drives the lifting plate to rise and fall. The clamping cylinder 750 is a clamping cylinder. The clamping block 751 has two clamping ends located on the clamping cylinder 750 respectively. The shape of the through groove 731 is the same as that of the clamping block 751. Specifically, the shape of the through groove 731 should be slightly larger than that of the clamping block 751, so that the clamping block 751 can be more easily inserted into the first shell 730 to clamp and fix the penultimate vessel, preventing the penultimate and subsequent vessels from falling.

[0074] Please continue reading. Figure 8 As shown, in order to facilitate the artificial replenishment of the vessel in the first shell 730, the first shell 730 has an opening and closing door, and new vessels can be added to the interior of the first shell 730 by opening the opening and closing door.

[0075] The second conveying device includes a vessel discharge conveying device 800, which includes a second conveying line 810. A second fixed frame 820 is provided at one end of the second conveying line 810. The second fixed frame 820 has a second clearance groove 821. A second lifting member 830 is provided below the second fixed frame 820. The telescopic end of the second lifting member 830 can extend into the second clearance groove 821. A one-way material passing structure 840 is provided on the sidewall of the second clearance groove 821 in the opposite direction. A second shell 850 is provided above the second fixed frame 820. The second shell 850 has a second receiving cavity, which communicates with the second clearance groove 821.

[0076] See Figure 3 and Figure 9 As shown, before the vessel feeding conveyor 700 provides new vessels, the used vessels need to be counted and conveyed to the vessel discharging conveyor 800. The vessel discharging conveyor 800 collects the used vessels. Specifically, the AGV trolley transports the used vessels held by the robotic arm to the first opening of the second hopper 300. Then, the first opening of the second hopper 300 is opened through the first closing door 400, and the robotic arm transports the used vessels onto the second conveyor line 810. The second conveyor line 810 then transports the old vessel to the second clearance groove 821. The second lifting member 830 lifts the old vessel at the position of the second clearance groove 821 upwards. As the old vessel is lifted upwards, it will be lifted into the second shell 850. Under the action of the one-way material conveying structure 840, it will not fall downwards. It can be understood that the one-way material conveying structure 840 only allows the old vessel to be lifted upwards from below into the second shell 850, and does not allow the old vessel in the second shell 850 to fall downwards.

[0077] Furthermore, to facilitate the manual removal of the old vessel from the second shell 850, the second shell 850 has an opening and closing door, through which the second shell 850 can be opened or closed, thereby facilitating the removal of the old vessel.

[0078] In one embodiment, the second lifting member 830 may consist of a cylinder and a lifting plate, i.e., the cylinder drives the lifting plate to move up and down.

[0079] The unidirectional material handling structure 840 includes mounting grooves 841 formed on the two opposite side frames of the second lifting member 830, and a flap 842 is rotatably mounted in the mounting grooves 841.

[0080] See Figure 9 and Figure 10 As shown, in order to allow the old vessel to enter the second shell 850 only from the bottom in one direction, an installation groove 841 is provided on the side wall opposite to the second clearance groove 821, and a flap 842 is rotatably installed in the installation groove 841. The flap 842 extends to support the old vessel in the second shell 850 and prevent it from falling downward. It can be understood that in the initial state, the bottom of the flap 842 is in contact with the bottom surface of the installation groove 841, thereby providing support for the old vessel.

[0081] The working process of this utility model is as follows: First, the second openings of the first hopper 200 and the second hopper 300 are opened through the second sealing door. The required materials are placed in the first hopper 200 and the old materials are removed from the second hopper 300. Then, the second sealing door closes the second openings of the first hopper 200 and the second hopper 300. When new materials are needed, the first sealing door 400 opens the first opening of the first hopper 200. The AGV and the robotic arm work together to remove the new materials from the first hopper 200 and move them to the predetermined location in the laboratory. When old materials need to be transported to the second hopper 300, the first sealing door 400 opens the first opening of the second hopper 300. The AGV and the robotic arm holding the old materials work together to transport the old materials to the second hopper 300, thus realizing the collection of old materials.
