Description

Technical Field

[0001] The present invention relates to a sample storage system, and in particular to a fully enclosed automatic sample storage system. Background Art

[0002] Sample storage is widely used in medical, chemical, biological, nuclear and other technical fields, and it is often necessary to centrally store and manage various samples. Generally speaking, if the storage environment requirements for samples are not high, samples can be stored in conventional storage rooms or cabinets, and the access method can be manual or automatic.

[0003] In actual applications, many samples have higher requirements for the storage environment. For example, they have specific requirements for temperature, cleanliness, vacuum, etc. The samples cannot be stored in conventional simple storage rooms or storage cabinets, but require a specific structural design for the storage space equipment to meet application requirements.

[0004] There are many application requirements for low-temperature preservation in traditional sample storage systems. Generally, an independent low-temperature preservation container is set up, and other related components such as a manipulator are used to achieve efficient automatic sample storage and retrieval functions. This type of system does not need to remain sealed during the storage and retrieval operation, but directly opens the storage space. The short-term temperature rise will not have an adverse effect on the low-temperature environment of the storage space. After the storage and retrieval operation is completed, the storage space is closed to seal it from the outside world to ensure low-temperature preservation. For example, the invention patent application with application number "202010128976.2" and name "A sample storage library and sample storage method" includes a sorting library and a storage library. The sorting library is equipped with a temporary storage rack, a scanning device, a test tube capping device, a test tube recovery device, a second manipulator, and a third manipulator. The storage library is equipped with a storage rack and a fourth manipulator, and the storage library is connected to the sorting library. The beneficial effects of this application are: the sample storage, out-of-stock, capping and recovery processes do not require manual intervention, and the sample can be fully automatically stored, which improves the efficiency of test tube storage. The storage repository applied for is a low-temperature storage facility, which needs to be isolated from the outside world. However, during the process of storing or retrieving samples, the storage repository is directly opened for easy operation.

[0005] However, the above-mentioned traditional sample storage system with low-temperature preservation cannot meet the requirements for the cleanliness and vacuum degree of the storage environment, because there is no sealed protection structure during the storage and access process, which will cause external dust to enter the storage space and pollute the internal environment, or cause external air to enter the storage space and increase the air pressure.

[0006] Therefore, there is currently no automated sample storage system that can keep the internal space sealed throughout the sample storage and retrieval process and can store a large number of samples, and it cannot meet the application requirements for the cleanliness and vacuum degree of the storage environment. Summary of the Invention

[0007] The object of the present invention is to provide a fully enclosed automated sample storage system that maintains the internal space sealed throughout the process of accessing samples and can meet the cleanliness and vacuum requirements of the storage environment.

[0041] Such as Figures 1-7As shown, the environmental cleanliness and vacuum degree in the sample storage chamber 1 are both pre-treated as required. When storing samples, taking the example that multiple sample reagent tubes 17 are placed in the sample box 16 here, first select the save option through the touch screen 2. The controller controls the outer sealing door 5 to open and the inner sealing door 10 to close. Then place the sample box 16 in the sample box installation groove 32 of the sample box installation part 19 of the sample transport plate 18. After placing it properly, the proximity sensor 27 sends a signal. The controller controls the outer sealing door 5 to close. At this time, both the transfer cavity 7 and the space where the sample picking and placing area is located are filled with external air. Then control the vacuum pump 24 to start, and pump out the gas in the transfer cavity 7 and the space where the sample picking and placing area is located outside the sample storage chamber 1. After it reaches the required vacuum degree, stop the operation of the vacuum pump 24. Then open the inner sealing door 10, and then start the sample transport motor 20. Under the transmission of the transmission screw and the transmission nut, the sample transport plate 18 moves backward until it is close to the installation table 25. Then turn off the sample transport motor 20, start the scanner 22 to collect and save the sample information, then start the manipulator 12, clamp the sample box 16 and place it in the corresponding compartment of the sample storage cabinet 11. Then start the sample transport motor 20 to make the sample transport plate 18 move forward until it returns to the initial position, and then close the inner sealing door 10, thus realizing the reset of the entire device and completing the storage process of one sample.

[0042] When taking out samples, first select the take-out option through the touch screen 2. The controller controls the inner sealing door 10 to open. Then start the sample transport motor 20, move the sample transport plate 18 backward until it is close to the installation table 25. Then turn off the sample transport motor 20, and then start the manipulator 12, clamp the sample box 16 from the corresponding compartment of the sample storage cabinet 11 and place it in the sample box installation groove 32 of the sample box installation part 19 of the sample transport plate 18. Then start the scanner 22 to collect and save the sample information. Then start the sample transport motor 20 to make the sample transport plate 18 move forward until it returns to the initial position. Then close the inner sealing door 10, and then open the outer sealing door 5. After the user takes away the sample box 16, the proximity sensor 27 sends a signal. The controller controls the outer sealing door 5 to close. Then control the vacuum pump 24 to start, and pump out the gas in the transfer cavity 7 and the space where the sample picking and placing area is located outside the sample storage chamber 1. After it reaches the required vacuum degree, stop the operation of the vacuum pump 24, realizing the reset of the entire device and completing the take-out process of one sample.

[0043] The above storage and retrieval of the sample box 16 are also applicable to the access operations of the sample reagent tubes 17 in the sample box 16. Only a vacuum chuck 31 is selected when the manipulator 12 holds them, and the other processes are the same. Meanwhile, during the sample replacement process, referring to the above storage process, after depositing, the sample box 16 to be retrieved is placed into the sample box installation groove 32 of the sample box installation part 19 of the sample transport plate 18 by the manipulator 12. The method for replacing the sample reagent tubes 17 is similar.

[0044] The above embodiments are only the preferred embodiments of the present invention and do not limit the technical solutions of the present invention.
