[0019] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] Example

[0021] See Figure 1-3 As shown:

[0022] This utility model provides a cold storage transfer channel, including: a door opening section, a door-opening sampling section, a cold air conveying section, and a transfer box 40. The transfer box 40 is equipped with a sample conveying section 30, and both ends of the transfer box 40 are connected to the operating room and the storage compartment, respectively. The door opening section is installed at the end of the transfer box 40 located in the operating room, forming an automatic opening and closing structure with that end. The door-opening sampling section forms an automatic opening and closing structure with the end of the transfer box 40 located in the storage compartment and is connected to the conveying section 30. The cold air conveying section is connected to the transfer box 40 and inputs cold air into the transfer box 40 when the conveying section 30 conveys samples.

[0023] When samples need to be transferred, the cold air delivery section opens, and the operator then opens the door, places the sample on the delivery section 30, closes the door, and opens the door-opening sampling section. The delivery section 30 then transports the sample to the door-opening sampling section until the sample is removed. The door-opening sampling section then closes, and the cold air delivery section shuts down. Throughout the operation, because the door and door-opening sampling sections open alternately, and the cold air delivery section continuously replenishes the low-temperature airflow during sample transport by the delivery section 30, the outflow of cold air from the transfer box 40 is minimized, ensuring the temperature requirements during sample transfer and improving the quality of sample storage.

[0024] The door opening section includes a first door panel 10, a tilting motor 11, and a first support frame 12. The first support frame 12 is installed at one end of the transfer box 40 located in the operating chamber. The tilting motor 11 is installed on the first support frame 12. The bottom of the first door panel 10 is connected to the rotating shaft of the tilting motor 11, and under the drive of the tilting motor 11, it forms an opening and closing structure with the end of the transfer box 40 located in the operating chamber.

[0025] By setting the first door panel 10 and the transfer box 40 to a flip-type opening and closing structure, it is not only convenient for operators to take samples, but also the first door panel 10, which is in a horizontal state after flipping, can serve as a temporary storage platform for samples, thus facilitating operation by operators.

[0026] The sampling unit mainly consists of a second door panel 20, a lifting motor, a second fixed frame 21, and a robotic arm 50. The second fixed frame 21 is installed at one end of the transfer box 40 located in the storage chamber; both the lifting motor and the second door panel 20 are installed on the second fixed frame 21, and the lifting motor is connected to the second door panel 20, driving the second door panel 20 to slide along the vertical direction of the second fixed frame 21; the second door panel 20 and the transfer box 40 at one end of the storage chamber form an opening and closing structure.

[0027] The robotic arm 50 is installed on one side of the second fixed frame 21, docks with the conveying unit 30, and automatically grabs the samples being transported on the conveying unit 30.

[0028] By placing the second door panel 20 and the transfer box 40 at one end of the storage chamber to form a lifting and opening structure, space can be saved and the robotic arm 50 can easily grasp the sample. Thus, there will be no interference between the two, reducing the failure rate and improving the efficiency of stable sample delivery.

[0029] The cold air delivery unit includes an upper air duct valve 41 and a lower air duct valve 42. Both the upper air duct valve 41 and the lower air duct valve 42 are located in the storage compartment. The upper air duct valve 41 is installed on the top of the transfer box 40, and the lower air duct valve 42 is installed on the bottom of the transfer box 40. Both the upper air duct valve 41 and the lower air duct valve 42 are connected to the transfer box 40.

[0030] Cryopreservation box entry: After the upper air duct valve 41 is opened, the first door panel 10 opens, the conveyor 30 extends, and after the manual placement of the cryopreservation box containing the sample, the conveyor 30 retracts to the transfer box 40 and is set to the middle position. The first door panel 10 closes, the upper air duct valve 41 closes, and the lower air duct valve 42 opens. The second door panel 20 opens, the conveyor 30 extends into the storage room, and after the robotic arm 50 inside the storage room removes the cryopreservation box, the conveyor 30 retracts to the middle position, the second door panel 20 closes, and the lower air duct valve 42 closes.

[0031] Cryopreservation box removal: After the upper air duct valve 41 is opened, the second door panel 20 opens, the conveyor 30 extends into the storage room, the robotic arm 50 places the cryopreservation box inside the storage room, the conveyor 30 retracts to the middle position of the transfer box 40, and the second door panel 20 closes; the first door panel 10 opens, the conveyor 30 extends, the cryopreservation box is manually removed, the conveyor 30 retracts to the middle position of the transfer box 40, the first door panel 10 closes, the upper air duct valve 41 closes, and the lower air duct valve 42 is opened for a period of time and then closed.

[0032] The conveying unit 30 mainly consists of a first conveying guide rail 31, a second conveying guide rail 32, a sample box fixing frame 33, a first drive motor 34, a reset chain 35, and a second drive motor 36. The bottom of the first conveying guide rail 31 is slidably connected to the inner wall of the bottom of the transfer box 40 and slides along the length of the transfer box 40 under the drive of the second drive motor 36; the bottom of the second conveying guide rail 32 is slidably connected to the top of the first conveying guide rail 31 and slides along the length of the first conveying guide rail 31 under the drive of the first drive motor 34; the sample box fixing frame 33 is installed on the top of the second conveying guide rail 32.

[0033] This setup enables a double-layer sliding mechanism, with the second conveying rail 32 extending from both ends of the transfer box 40, allowing it to move a longer distance within a limited space, facilitating the placement of samples onto the sample box holder 33.

[0034] One end of the reset chain 35 is connected to the side wall of one end of the second conveying guide rail 32, and the other end is connected to the side wall of the middle part of the first conveying guide rail 31, thereby limiting the first conveying guide rail 31 from moving too far on the second conveying guide rail 32. This takes into account the requirements of sample conveying distance, and also avoids the instability of the center of gravity of the second conveying guide rail 32.

[0035] It also includes a channel support frame 43; the channel support frame 43 is installed in the operating room and connected to the bottom of the transfer box 40 to provide stable support for the transfer box 40.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
