Description

Technical Field

[0001] This application relates to the field of biological sample storage and delivery equipment technology, and in particular to an intelligent double-sided delivery window for automated delivery of biological samples. Background Technology

[0002] In biological laboratories, medical sample banks, and cryogenic cold chain storage scenarios, biological samples need to be transferred across regions in a low-temperature, clean, and sealed environment. As a core device for sample transfer between isolated areas, the transfer window's level of automation, sealing performance, and operational accuracy directly affect sample storage safety and transfer efficiency. Traditional transfer windows typically use manual opening and placement, requiring operators to frequently open the window and manually transfer samples. This is not only inefficient but also prone to causing cold air leakage from the low-temperature environment, prolonged cold exposure time for samples, and increased risk of cross-contamination.

[0003] With the development of automation technology, some pass-through windows have achieved electric opening and closing, but there are still defects such as redundant drive systems, low motion control precision, and lack of interlock protection mechanisms. Because the opening and closing of windows and doors and the translation of trays in traditional automation technology are mostly controlled by multiple independent motors, their linkage and synchronization are poor. Moreover, traditional control often uses open-loop control or a single limit switch, which makes it difficult to control the opening and closing of windows and doors and the extension position of trays, resulting in low motion control precision and easy to cause collisions or pinching damage. In addition, traditional pass-through windows mostly rely on manual intervention to open and close windows and doors, lacking a double-sided window and door interlock protection mechanism, which can easily lead to the simultaneous opening of both doors, causing air convection between clean and non-clean areas and destroying the sealed environment of the cavity.

[0019] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The following is combined with Figures 1-7 This application describes an intelligent double-sided transfer window for automated transfer of biological samples, as provided in the embodiments of this application.

[0021] Reference Figure 1-3As shown, this embodiment provides an intelligent double-sided transfer window for automated transfer of biological samples. The transfer window is fixedly installed on a clean / low-temperature isolation wall 1 via through-wall panels 2. It mainly includes a window body, double-sided transfer window doors 5, a window door drive assembly 8, a gear transfer assembly 9, and a control system. The window body is a frame structure enclosed by multiple through-wall panels 2, with an overall rectangular box structure, and is embedded inside the wall 1. The through-wall panels 2 completely surround the outer edge of the window body, serving to fix, seal, and protect the wall interface. The double-sided transfer window doors 5 are symmetrically arranged on both sides of the window body, facing different areas on both sides of the wall 1, to achieve double-sided transfer of biological samples across the wall.

[0022] Specifically, such as Figure 4 As shown, the window is a hollow rectangular cavity, and two sliding rail mounting plates 18 are fixed inside. The double-sided transfer windows 5 are symmetrically installed at the left and right ends of the window, specifically including a first window door and a second window door that open in opposite directions. The inner edges of the first window door and the second window door are surrounded by sealing strips 6, so that they can be pressed tightly against the window opening when the door is closed, so that a sealed cavity is formed inside the window.

[0023] Both sides of the first and second windows are equipped with hinged rods 7. The hinged rods 7 are arranged vertically or horizontally on the inside of the windows via corresponding hinge seats, and their other ends are hinged to the window drive assembly 8 via a pivot or hinge seat.

[0024] In some specific embodiments, the cover assembly is divided into an outer cover 3 and an inner cover 4. The outer cover 3 and the inner cover 4 are double-sealed and cover the outside of the window, forming the external protection and operation interface of the transfer window. The outer cover 3 has a power switch button integrated on the front for controlling the start and stop of the equipment; an NFC identification module 15 and a face recognition module 16 are arranged on the left side to realize identity verification and access control. At the same time, a power socket 11 and a network socket 12 are also provided at the bottom of the left side. The two interfaces are physically separated to realize the isolation of strong and weak current interfaces; a display screen 13 is installed on the right side, which can be used to display the temperature of the cavity inside the window, the status of the window and door, the transfer progress, fault information, etc. in real time. Below the display screen 13, there is a fan hood 14, which is a grid-shaped ventilation opening that is precisely aimed at the internal electrical heat source to form a directional heat dissipation air channel. A cooling fan can also be installed inside to enhance the heat dissipation effect; an electrical cabinet door 17 is also opened on the outer side of the outer cover. It is a detachable door panel structure for later maintenance of internal electrical components. The inner cover 4 and the outer cover 3 fit together vertically. The inner cover 4 also has an internal power switch button at the corresponding position to the external power switch button, enabling dual-sided operation control. Furthermore, the outer cover 3 integrates a voice control module for voice command recognition, facilitating remote control.

[0025] Two sets of window / door drive assemblies 8 are provided, located on opposite sides of the window. Each set of window / door drive assemblies 8 includes a motor 81, a drive slider 82, a drive sensor block 83, a first sliding guide rail 86, and a sensor groove 84 equipped with at least one position sensor 85. Specifically, as shown... Figure 5 and Figure 6 As shown, the first sliding guide rail 86 is located on the inner wall of the window. One end of the drive slider 82 is slidably mounted inside the first sliding guide rail 86 via a transmission slider 87, and is connected to the output end of the motor 81 via a lead screw. The drive sensing block 83 is fixedly mounted on the drive slider 82 and is slidably connected to the sensor groove 84, or its position is opposite to the sensor groove 84. Two transmission sliders 87 are slidably mounted on the first sliding guide rail 86, and the two sides of the first and second window doors are respectively hinged to the corresponding two transmission sliders 87 via hinged pull strips 7.

[0026] Specifically, the transmission slider 87 includes a first transmission slider and a second transmission slider. The first transmission slider is fixedly connected to the drive slider 82 via a connecting plate. The left and right sides of the same window door are respectively connected to the first transmission slider of one window door drive assembly 8 and the second transmission slider of the other window door drive assembly 8 via hinged pull bars 7. In actual operation, the motor 81 drives the lead screw to rotate, causing the drive slider 82 to move linearly along the arrangement direction of the first sliding guide rail 86, thereby causing the transmission slider to slide on the first slide rail. Through the linkage between the transmission slider 87 and the hinged pull bars 7, the linear motion is converted into the opening or closing action of the window door.

[0027] Multiple position sensors 85 are spaced apart along the direction of movement within the sensor slide 84, each electrically connected to the control system, with at least one sensor present. In this embodiment, each sensor slide 84 contains two position sensors 85, with the positions of the two position sensors 85 corresponding to the positions of the drive sensing block 83 when a window or door is fully open and when it is fully closed, respectively. The position sensor 85 located when the window or door is fully open is called the opening position sensor, and the position sensor 85 located when the window or door is fully closed is called the closing position sensor.

[0028] The specific control logic is as follows: First, when the drive sensing block 83 passes the opening position sensor under the drive slider 82, it means that the window has been fully opened. The control system receives the position signal transmitted by the opening position sensor and controls the corresponding motor 81 in the window drive assembly to stop. Then, the control system controls the gear transmission assembly 9 to drive the pallet to move towards this side window, thereby receiving or delivering the transfer box.

[0029] After the gear transmission assembly 9 retracts to its original position, the corresponding motor 81 of the side window drive assembly is reversed, which in turn drives the corresponding drive slider 82 to move in the opposite direction. Under the action of the hinge bar 7, the side window is pulled to close. When the drive sensor block 83 passes the closing position sensor under the action of the drive slider 82, it indicates that the side window is completely closed. After receiving the position signal transmitted from the closing position sensor, the control system can control the motor in the side window drive assembly to stop again and control the motor in the other side window drive assembly to start running. The above control logic is repeated to control the other side window drive assembly to open or close, and to detect whether it is fully open or closed. The control system will only control the motor in the other side window drive assembly to run when it detects a position signal from the closing position sensor on one side, thereby achieving a dual safety interlock of physical and electrical safety.

[0030] In another embodiment, when only one position sensor is installed, the position sensor is centrally located at the center of the first and second windows. In this case, the windows can be precisely controlled by independent electric or hydraulic push rods. That is, the window drive assembly 8 is no longer used to drive the windows, and the motor 81 can be removed. The drive slider 82 is connected to the support plate 95 via a connecting rod, and is moved by the support plate 95. Initially, both windows are closed, the support plate 95 retracts into the window, and the drive sensing block 83 faces the position sensor. When the support plate 95 moves to one side, the drive sensing block 83 leaves the sensing range. At this time, the control system loses the position information at the position sensor, and the control system controls the independent push rod on that side to open the window. This allows the gear transmission assembly 9 to extend the support plate 95 outwards. When the support plate 95 retracts the received transfer box 10 into the window, the position sensor will detect the position information of the drive sensing block again, and the control system can then control the window on that side to close. Subsequently, under the control of the control system, the gear transmission assembly 9 will drive the pallet 95 to move towards the window on the other side, and repeat the above control logic to transfer the transfer box 10. The window control logic and opening sequence are pre-set and will not be elaborated here.

[0031] In some specific embodiments, such as Figure 6 and Figure 7As shown, the gear transmission assembly 9 is installed between the two slide rail mounting plates 18, including a meshing gear 91 and a rack 92, a gear fixing bracket 93 for fixing the gear, and a gear drive motor for driving the gear. The gear 91 is precision-machined, achieving a transmission accuracy of 0.1mm to precisely control the transmission distance. A support plate 95 is fixed above the rack 92, and two second sliding rails 96 are fixed to the bottom of the support plate 95, located on both sides of the rack 92. The support plate 95 slides on the two slide rail mounting plates 18 via the two second sliding rails 96. A drag chain 94 is also installed on one side of the gear fixing bracket 93 or one of the second sliding rails 96 to accommodate and guide the follower cable, preventing the cable from tangling or wearing during reciprocating motion.

[0032] In some specific embodiments, the control system includes a control module and a communication module. The control module establishes a handshake communication protocol with the external handling robot through the communication module and can perform bidirectional interaction of sample status data with the upper-level LIMS / MES system. Furthermore, the control system can verify the operator's or robot's permissions based on the recognition results of the NFC and facial recognition modules, and record and transmit operation logs. To further enhance the device's anti-pinch and status monitoring capabilities, foreign object detection light curtains and door status sensors can be installed at windows and doors to improve its operational accuracy.

[0033] In addition, for applications in low-temperature environments, a micro-heating defrosting strip can be added to the inside of the window and the corresponding slide rail to prevent low-temperature condensate from frosting and blocking the normal operation of the window and door drive assembly 8 and the gear transmission assembly 9.

[0034] The intelligent double-sided transfer window provided in this application achieves precise closed-loop control of window opening and closing and tray displacement through the mechanical linkage and coordinated control of the window door drive assembly 8 and gear transmission assembly 9, utilizing the cooperation of the drive sensing block 83 and multiple position sensors 85 within the sensor slide 84. This reduces the possibility of mechanical impact and improves transmission stability. Simultaneously, the logical interlocking design of the control system ensures that only one window can be opened at a time, effectively maintaining the isolation between the low-temperature and clean environments. Furthermore, by integrating NFC, facial recognition, and robot handshake communication protocols, high-security automatic transfer and data traceability are achieved in unattended scenarios. The micro-heating defrosting strips installed on the inner side of the window and the slide rails eliminate the risk of transmission jamming caused by condensation and frost under low-temperature conditions. The external cover adopts a strong and weak current physical isolation and directional heat dissipation air duct design, enhancing the safety and reliability of the electrical system.

[0035] The working process of the pass-through window in this application in an unattended scenario is as follows: The external handling robot sends a transfer request signal. After the control system verifies the authorization, it controls the target side window door drive assembly 8 to open the window door, and the gear transmission assembly 9 drives the pallet 95 to extend. After the robot places the transfer box 10 on the pallet 95, the gear transmission assembly 9 drives the pallet 95 and the transfer box 10 to retract into the window, and the drive sensor block 83 triggers the closing station sensor, and the window door on that side closes automatically. Subsequently, the other side window door opens, the pallet 95 extends, and the transfer box is handed out, completing the cross-area transfer. The entire process can operate fully automatically in a closed loop, thereby reducing manual intervention.

[0036] This application enables automatic sample reception, transfer, and delivery through the linkage of the control system and the handling robot, eliminating the need for manual intervention and adapting to unattended low-temperature sample transfer scenarios.
