Description

Technical Field

[0001] This utility model relates to the field of laboratory testing equipment, specifically to an integrated biological experimental well plate inlet / outlet chamber. Background Technology

[0002] In biological culture experiments, it is necessary to frequently place and remove well plates into and from the chamber. Currently available testing systems use a robotic arm to clamp the well plates into designated positions on the chamber, followed by manual opening of the chamber door and retrieval. Biological culture experiments are highly sensitive to environmental conditions, and human intervention can negatively impact these conditions. When hands are inside the equipment, they interfere with the stability of the experimental environment, altering key parameters such as temperature, humidity, and cleanliness. Under the same conditions, hand contact with the instrument can adversely affect the accuracy and reliability of drug sensitivity testing, leading to deviations in results and hindering the smooth progress of the experiment. Furthermore, reaching inside the instrument while it is operating poses safety hazards; pausing sampling interrupts the process and reduces the instrument's efficiency.

[0003] Some manufacturers control the entry and exit of the orifice plate through a drive device. For example, a structure for entering and exiting the orifice plate is disclosed in patent CN202421140489.8, which belongs to the field of blood culture instruments. It includes an orifice body, a drive mechanism, a sliding component, and a support. The orifice body includes a base plate. The support is slidably installed on the orifice body through the sliding component. The drive mechanism is installed on the base plate and is connected to the support through a transmission. The drive mechanism is located below the support and the driving direction of the drive mechanism is the same as the guiding direction of the sliding component. The support is provided with a receiving chamber.

[0004] The solution uses a drive mechanism to guide the sliding mechanism to automatically move the support into and out of the compartment. However, the compartment door cannot automatically open or close with the tray, and still needs to be opened or closed manually, so it cannot achieve fully automatic operation. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated biological experimental plate entry and exit chamber. Through the rebound component and sliding mechanism, the chamber door is automatically opened and closed during the entry and exit of the plate, eliminating the need for manual opening and closing by staff. This greatly reduces human intervention, improves work efficiency, avoids the influence of human hands on the experimental environment, and ensures the accuracy of the experiment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides an integrated biological experimental well plate inlet / outlet chamber, comprising:

[0008] frame;

[0009] A compartment door, which is rotatably mounted on the frame via a spring-loaded mechanism;

[0010] A tray is movably mounted on the frame, and a drive device is provided on the frame to drive the tray to move relative to the frame;

[0011] A sliding mechanism is provided on the tray, and the tray and the compartment door slide relative to each other through the sliding mechanism.

[0012] Preferably, the sliding mechanism is a roller, which is disposed on the support plate and used to abut against the compartment door.

[0013] Preferably, the spring-loaded component is a torsion spring.

[0014] Preferably, the frame is equipped with a perforated plate sensor, which is used to sense whether the perforated plate is being fed.

[0015] Preferably, the orifice plate sensor is an optocoupler sensor.

[0016] Preferably, the orifice plate sensor is electrically connected to an indicator light.

[0017] Preferably, a reset sensor is provided on the frame, which is used to sense whether the orifice plate has been reset.

[0018] Preferably, the frame is equipped with a barcode scanner, which is used to scan the information code on the perforated plate.

[0019] Preferably, the frame is provided with a slide rail, the pallet is provided with a rack, the drive device is provided with a gear, the pallet is disposed on the slide rail, and the rack meshes with the gear.

[0020] Preferably, the drive device is electrically connected to a manual induction switch.

[0021] This utility model has at least the following beneficial effects:

[0022] In this embodiment, the biological experimental plate enters and exits the chamber through a spring-loaded mechanism and a sliding mechanism, which enables the automatic opening and closing of the chamber door during the process of the plate entering and exiting. This eliminates the need for manual opening and closing by staff, greatly reducing human intervention, improving work efficiency, avoiding the impact of human hands on the experimental environment, and ensuring the accuracy of the experiment.

[0023] The pallet drives the door to rotate via rollers. The friction between the two is small, which reduces the driving force required and prevents damage to components due to friction, thus improving service life.

[0024] The perforated plate sensor monitors the situation on the pallet in real time. When the perforated plate is detected, the sensor will send a signal to provide accurate signal basis for subsequent operation procedures, thereby realizing the automated management and scheduling of the perforated plate.

[0025] During the orifice plate reset process, the reset sensor monitors it in real time. When it detects that the orifice plate has reached the starting position, it sends a stop signal to the drive device. Attached Figure Description

[0033] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-2 As shown, an embodiment of this utility model provides an integrated biological experimental plate inlet / outlet chamber, including a frame 1, a chamber door 2, a tray 4, and a sliding mechanism 6. The chamber door 2 is rotatably mounted on the frame 1 via a spring-loaded component 3; the tray 4 is movably mounted on the frame 1, and a driving device 5 is provided on the frame 1, which drives the tray 4 to move relative to the frame 1; the sliding mechanism 6 is provided on the tray 4, and the tray 4 and the chamber door 2 slide relative to each other through the sliding mechanism 6.

[0035] The workflow for the integrated biological experimental plate entering and exiting the chamber in this embodiment is as follows: First, the robotic arm places the plate 16 from the previous process onto the tray 4. After appropriate processing, the operator issues a removal command, and the drive device 5 drives the tray 4 and the plate 16 on the tray 4 to move towards the chamber door 2. When the tray 4 moves a certain distance, the sliding mechanism 6 on the tray 4 abuts against the chamber door 2. The tray 4 continues to move forward, and the sliding mechanism 6 slides relative to the chamber door 2. The chamber door 2 rotates and opens under the push of the sliding mechanism 6. When the tray 4 moves to a predetermined distance, it stops moving, and the robotic arm removes the plate 16. After confirmation by the operator, a reset command is issued, and the drive device 5 drives the tray 4 to move in the opposite direction to return to the starting position. During the return process, the sliding mechanism 6 gradually disengages from the chamber door 2, and the chamber door 2 rotates back to its initial state under the traction of the return spring 3.

[0036] In this embodiment, the integrated biological experimental plate enters and exits the chamber through the spring-loaded component 3 and the sliding mechanism 6, realizing the automatic opening and closing of the chamber door 2 during the entry and exit of the tray 4. This eliminates the need for manual opening and closing by staff, greatly reducing human intervention, improving work efficiency, avoiding the impact of human hands on the experimental environment, and ensuring the accuracy of the experiment.

[0037] In a preferred embodiment, the sliding mechanism 6 is a roller mounted on the support plate 4 to abut against the compartment door 2. The support plate 4 pushes the compartment door 2 to rotate via the roller. The friction between the two is small, reducing the driving force required and preventing damage to components due to friction, thus improving service life. Multiple rollers can be provided to ensure that the compartment door is always in contact with the rollers.

[0038] In a preferred embodiment, the spring-loaded component 3 is a torsion spring. Torsion springs are easy to install and remove, inexpensive, and offer high cost-effectiveness.

[0039] In a preferred embodiment, a perforated plate sensor 7 is installed on the frame 1. The perforated plate sensor 7 is used to detect whether the perforated plate 16 is being loaded. The perforated plate sensor 7 monitors the status of the tray 4 in real time. When the perforated plate 16 is detected, the perforated plate sensor 7 sends a signal, providing accurate signal basis for subsequent operation processes, thereby realizing automated management and scheduling of the perforated plate 16. The perforated plate sensor 7 can be an optocoupler sensor. For optocoupler sensors, a detection port 15 needs to be opened on the tray 4 for the perforated plate sensor 7 to perform detection. Figure 3 As shown in the image.

[0040] In a preferred embodiment, the perforation plate sensor 7 is electrically connected to the indicator light 8. Two indicator lights 8 can be provided, representing the presence and absence of the perforation plate respectively, thereby reminding the staff to perform the corresponding operations.

[0041] like Figure 4 As shown, in a preferred embodiment, a reset sensor 9 is provided on the frame 1. The reset sensor 9 is used to sense whether the orifice plate 16 has been reset. During the reset process of the orifice plate 16, the reset sensor 9 monitors it in real time. When it detects that the orifice plate 16 has reached the starting position, it sends a stop signal to the drive device 5.

[0042] In a preferred embodiment, a barcode scanner 10 is installed on the frame 1. The barcode scanner 10 is used to scan the information codes on the perforated plates 16. For perforated plates 16 exiting the chamber, the barcode scanner 10 verifies the information to ensure that the information of the exiting perforated plates 16 is accurate. For perforated plates 16 entering the chamber, the barcode scanner checks the information to prevent errors or the inclusion of non-compliant perforated plates 16. This comprehensive approach ensures the accuracy of the perforated plate 16 information and lays a solid foundation for the precise implementation of the experimental process.

[0043] In a preferred embodiment, the frame 1 is provided with a slide rail 11, the tray 4 is provided with a rack 12, and the drive device 5 is provided with a gear 13. The tray 4 is mounted on the slide rail 11, and the rack 12 meshes with the gear 13. The drive device 5 can be a stepper motor, which drives the gear 13 and the rack 12 to ensure that the device can stably perform entry and exit operations according to preset requirements.

[0044] In a preferred embodiment, the drive unit 5 is electrically connected to the manual sensor switch 14. The switch controlling the operation of the drive unit 5 can be a manual sensor switch, installed on the door 2, or a switch can be installed on the equipment control interface.

[0045] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
