Detailed Implementation

[0022] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model.

[0023] This application designs an automated low-temperature storage device, as shown in the attached document. Figure 1-2 As shown, it includes cabinet body 1, cabinet door 2, placement opening 3, storage cabinet 4, conveying mechanism 5, closing door 53, electric lifting screw 6, barcode scanner 7, and rotating mechanism 8;

[0024] Cabinet door 2 is located on the front of cabinet 1, and placement opening 3 is located on the back of cabinet 1. A barcode is affixed to the outside of the sample box.

[0025] The storage cabinet 4 is composed of multiple centrally symmetrical freezers. The storage cabinet 4 is rotatably connected to the inner wall of the cabinet body 1. The storage cabinet 4 is driven by a controller. The inner wall of the storage cabinet 4 has multiple vertically arranged slots for fixing the sample boxes.

[0026] The conveying mechanism 5 is located inside the placement opening 3, and the closed door 53 connected to the conveying mechanism 5 is located outside the placement opening 3.

[0027] The barcode scanner 7 and the electric lifting screw 6 are respectively installed on both sides of the conveying mechanism 5. The rotating mechanism 8 is connected to the electric lifting screw 6, and the electric lifting screw 6 is used to lift the rotating mechanism 8.

[0028] As attached Figure 3 As shown, the conveying mechanism 5 includes an electric slide rail 51, a connecting rod 52, and a synchronous belt 54;

[0029] The electric slide rail 51 is installed inside the cabinet 1. The slider part of the electric slide rail 51 is rotatably connected to the connecting rod 52. The end of the connecting rod 52 away from the electric slide rail 51 is rotatably connected to the closed door 53. The closed door 53 is used to close the placement opening 3.

[0030] The synchronous belt 54 is installed between the electric slide rail 51 and the electric lifting screw 6. The synchronous belt 54 is used to transport the sample box to the barcode scanner 7.

[0031] As attached Figure 4 As shown, the rotating mechanism 8 includes a tray 81, a drive motor 82, a telescopic motor 83, and a shovel 84;

[0032] The tray 81 is connected to the drive motor 82. The movement trajectory of the tray 81 is zigzag, which can be achieved by existing crank-connecting rod mechanisms or similar methods, so it will not be elaborated here. Compared with the arc-shaped rotation trajectory, it can save more internal space of the cabinet 1 and avoid the tray 81 getting stuck. The drive motor 82 drives the lifting and lowering through the electric lifting screw 6. The top of the tray 81 is movably connected to the shovel plate 84. The shovel plate 84 is driven to move forward and backward through the telescopic motor 83. The top outer periphery of the shovel plate 84 is provided with a rim, which is used to fix the sample box and prevent the sample box from falling off during the extension and retraction of the shovel plate 84. The width of the shovel plate 84 is slightly smaller than the width of the sample box, so that both sides of the sample box are located outside the shovel plate 84, making it easy for the sample box to be stuck in the slot.

[0033] The electric lifting screw 6 is equipped with a wiring protection sleeve on its outer side. The wiring parts of the drive motor 82 and the telescopic motor 83 are installed inside the wiring protection sleeve to prevent the wiring parts from being broken or damaged due to frequent rotation and lifting.

[0034] Working principle:

[0035] Warehouse entry:

[0036] S1: The electric slide rail 51 pushes the closed door 53 to open via the connecting rod 52, and then the sample box is placed in. After the sample box is placed in, the closed door 53 closes to reduce the loss of cold air.

[0037] S2: Synchronous belt 54 transports the sample box to the position of barcode scanner 7. Barcode scanner 7 scans and identifies the barcode on the sample box to determine the storage location of the sample box.

[0038] S3: The storage cabinet 4, which is used to store the sample box, rotates to the electric lifting screw 6. The telescopic motor 83 drives the shovel 84 to move radially to the position of the synchronous belt 54 and shovels up the sample box. Then the telescopic motor 83 drives the shovel 84 and the sample box to reset.

[0039] S4: Drive motor 82 drives tray 81 to move along the zigzag trajectory, moving tray 81, shovel 84 and sample box to the storage direction, and then electric lifting screw 6 drives tray 81 to rise to the storage position;

[0040] S5: The telescopic motor 83 pushes the shovel plate 84 into the storage cabinet 4, so that the sample box is stuck in the slot. Then the electric lifting screw 6 drives the tray 81 and the shovel plate 84 to descend slightly, so that the sample box is separated from the shovel plate 84. Then the shovel plate 84 and the tray 81 are reset in sequence until the tray 81 returns to the initial position to wait for the next sample box to enter, thus completing the warehousing process.

[0041] Outbound: Staff select the sample box to be retrieved via the control panel. The storage cabinet 4, which is used to store the sample box, rotates to the electric lifting screw 6. Then, the electric lifting screw 6 moves in the opposite direction to the inbound process. The sample box is removed by the extension and retraction of the shovel 84. This process is the reverse of the inbound steps. The barcode scanner 7 identifies the barcode on the sample box to prevent incorrect retrieval. If an incorrect sample box is retrieved, it is reset and retrieved manually. If the correct sample box is retrieved, it is transported via the synchronous belt 54. Finally, the sealing door 53 is opened to retrieve the sample box, thus completing the outbound process.

[0042] Inspection: After opening cabinet door 2, staff verify the number and number of sample boxes stored inside storage cabinet 4. When storage cabinet 4 is empty, sample boxes can be manually replenished. Manual removal and placement are also possible to facilitate the inspection of the equipment's working status. When the automatic inbound and outbound components malfunction or are damaged, manual removal and placement of sample boxes can be used to improve the equipment's applicability.

[0043] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
