Description

Technical Field

[0001] The utility model relates to the technical field of automated storage and transportation, in particular to an automated sample library cryobox storage, positioning and fixing mechanical structure, which is suitable for the storage and positioning of cryoboxes in the fields of biological samples, medical samples, etc. Background Art

[0002] In existing automated sample libraries, cryopreservation boxes are often not firmly positioned in the storage position, which can easily cause the box to be bumped and moved by other automated components during storage, resulting in displacement and skewness. The displacement and skewness of the storage position of the cryopreservation box can cause problems such as tube drop, tube jam, and box jam during storage and transportation, affecting subsequent access and identification, and increasing the risk of sample damage. Therefore, a cryopreservation box storage positioning mechanical structure is urgently needed to reduce the risks caused by factors such as displacement and skewness of the cryopreservation box during automated storage. Summary of the invention

[0003] The utility model provides an automated sample library cryopreservation box storage and positioning mechanical structure to solve the above problems. The technical solutions adopted are as follows:

[0004] An automated sample library cryopreservation box storage positioning mechanical structure includes a positioning device and a transport device. The positioning device is composed of a block 1, a guide rail 2, a card block 3, a card slot 4, a spring 5, and a slider 6. The transport device is composed of a cryopreservation box limit block 7, a card block top plate 8, a telescopic support plate 9, a transport box mechanism installation support plate 10, and a telescopic drive servo motor 11. The telescopic drive servo motor 11 controls the action flow of the transport device, places the cryopreservation box on the positioning device, and the positioning device automatically clamps and fixes the cryopreservation box.

[0005] The beneficial effects of the utility model are as follows: the utility model can accurately and quickly determine the position of the cryobox through a mechanical structure, and clamp and fix the cryobox, thereby solving the problems of tube drop, tube jam, and box jam during storage and transportation of samples caused by offset and skew of the storage position of the cryobox, and has high practical value and application value.

[0011] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0012] like Figure 1 As shown, the utility model comprises a positioning device and a transfer device.

[0013] like Figure 2 , Figure 3 , Figure 4 As shown, the positioning device is composed of a stopper 1, a guide rail 2, a clamping block 3, a clamping groove 4, a spring 5, and a slide block 6.

[0014] like Figure 5 As shown, the conveying device is composed of a freezing box limit block 7, a card block top plate 8, a telescopic support plate 9, a transfer box mechanism mounting support plate 10, and a telescopic driving servo motor 11.

[0015] When the frozen box is stored, the telescopic support plate 9 installed on the support plate 10 of the transport box mechanism is driven by the telescopic driving servo motor 11 of the conveying device to move forward, and a card block top plate 8 is provided on the top of the telescopic support plate 9. A spring 5 is installed at the front end of the frozen box storage position of the positioning device, and a sliding card block 3 is placed in front of the spring 5. The card block 3 is sent to install the guide rail 2 and the slider 6. When the card block is pushed by the card block top plate, it moves through the slider and the guide rail. Blocks 1 are installed on both sides of the card block 3, and a frozen box slot 4 is set at the rear end of the frozen box storage position of the positioning device. The card block top plate 8 pushes the card block 3 to move backward. When the card block 3 is pushed to the position flush with the block 1, the conveying device moves downward to place the frozen box on the frozen box storage position. The card block 3 pushes the frozen box to the frozen box slot 4 under the thrust of the spring 5, and the frozen box is clamped and fixed.

[0016] A freezing box guide limit block 7 is installed on the telescopic support plate 9 of the conveying device to prevent the freezing box from deviating in the conveying direction and correct the conveying position of the freezing box.

[0017] When the freezing box is taken out, the block top plate 8 pushes the block 3 to move backward, and the freezing box guide limit block 7 pushes the freezing box away from the slot 4, releasing the freezing box from being clamped and fixed by the slot 4 and the block 3, thereby taking the freezing box out of the positioning device.

[0018] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
