[0044] The technical solution of the present invention will be further explained below with reference to the examples and drawings.

[0045] After removal, the biological samples are stored in biological sample cryotubes. Multiple biological sample cryotubes are stored together in a storage box 1000, and the multiple storage boxes 1000 are stored in a sample storage tank 2000 for low temperature storage. A basket 3000 is provided in the sample storage tank 2000, and the multiple storage boxes 1000 are stored in the basket 3000, making storage and removal easy. The conventional low-temperature environment of the sample storage tank 2000 is provided by a nitrogen supply, i.e., a liquid nitrogen tank. To remove the biological sample cryotubes from the sample storage tank 2000, first open the lid 4000 of the sample storage tank 2000, remove the storage box 1000 from the basket, place the storage box 1000 in a transport box 701, and transport the sample using the transport box 701. Note that the sealing performance of the lid 4000 is important, and a lid-opening mechanism for removal may be provided to ensure a low-temperature environment within the sample storage tank 2000. Next, the sample storage tank is opened to remove the basket 3000, and the target cryotube is removed from the basket 3000. Of course, the storage and removal process is different from the above process, and will not be described in detail here.

[0046] Example 1 In the above operation process, the present invention discloses an unloading operation chamber 1 that can unload the sample storage tank 2000 in a sealed low-temperature environment, open the cover 4000, and then unload the cryotube from the basket 3000. This provides operation space in both the Z-axis and X-axis directions, and the unloading structure has a reasonable design, occupies little space, is low-cost, is intelligent and easy to operate, and has high sealing and heat retention properties.

[0047] This embodiment provides a removal operation room, which includes a multi-stage Z-direction removal arm 11 and an X-direction push system 12. The multi-stage Z-direction removal arm 11 is an arm that allows movement over multiple sections in the Z-axis direction. The multi-stage Z-direction removal arm 11 is provided with a removal member 111, which can move the removal member 111 in the Z-axis direction. The X-direction push system 12 is provided at a position corresponding to the removal member 111, and the X-direction push system 12 can push the lid 4000 or storage box 1000 of the sample storage tank 2000 removed by the removal member 111 to a predetermined position.

[0048] The multi-stage Z-direction take-out arm 11 (in this embodiment, the Z direction is the vertical direction, and the same will not be described in detail below) disclosed in this invention may be a Z-direction manipulator or a Z-direction drive arm, and is not limited thereto. Arms that realize multi-section and multi-distance movement are within the scope of protection of this invention. The cooperation of the multi-stage Z-direction take-out arm 11 and the X-direction push system 12 greatly reduces the occupied space, is low cost, is intelligent and easy to operate, and has high sealing and heat retention. In the prior art, three-axis manipulators are often designed, which not only occupy a large space but also have poor sealing and heat retention.

[0049] In this embodiment, as a preferred embodiment of the multi-stage Z-direction take-out arm 11, the multi-stage Z-direction take-out arm 11 includes a first Z-direction take-out arm 112, a second Z-direction take-out arm 113, and a lateral drive receiving arm 114; The lateral drive receiving arm 114 is mounted on the first Z-direction retrieval arm 112, and the first Z-direction retrieval arm can move the lateral drive receiving arm in the Z-axis direction. The second Z-direction retrieval arm 113 is mounted on the lateral drive receiving arm 114, and the lateral drive receiving arm can move the second Z-direction retrieval arm laterally in the X-axis direction. The retrieval member 111 is mounted on the second Z-direction retrieval arm 113, and the second Z-direction retrieval arm can move the retrieval member up and down in the Z-axis direction. The first Z-direction retrieval arm can move the lateral drive receiving arm vertically in the Z-direction, and the lateral drive receiving arm allows the second Z-direction retrieval arm to vertically move the operating movement portion of the first Z-direction retrieval arm. The second Z-direction retrieval arm itself has an operable vertical movement portion in the Z-axis direction, providing two sections of operating portions in the vertical direction of the Z-axis, thereby significantly increasing the depth and length of vertical operation. In addition, a lateral drive receiving arm is provided to move the second Z-direction fetch arm in the lateral X direction, thereby enabling the second Z-axis fetch arm to move in the X-axis direction. This design has a small footprint, high stability, and a wide operating distance.

[0050] In order to cooperate well with the X-direction pushing system, this embodiment further discloses a more specific form of the multi-stage Z-direction take-out arm, namely, the first Z-direction take-out arm includes a Z-direction driving sub-electric cylinder A115, a Z-direction driving sub-electric cylinder B116, a Z-direction rail A117, and a Z-direction rail B118, and the lateral driving receiving arm 114 includes a driving rail C119 and a driving electric cylinder C120, The Z-direction rails A117 and B118 are fixed vertically and symmetrically in the Z-axis direction within the removal operation chamber 1. Both ends of the drive rail C119 are slidably mounted on the Z-direction rails A and B, respectively. The Z-direction drive sub-electric cylinder A and Z-direction drive sub-electric cylinder B move both ends of the drive rail C119 up and down, respectively. The Z-direction rails A117 and B118 are symmetrically mounted, and the space between the Z-direction rails A and B provides the operating space for the X-direction push system 12. The position of the X-direction push system 12 can be determined according to the removal member, resulting in a more reasonable structural design. When the removal member removes the lid 4000 of the sample storage tank 2000, the removal position is between the Z-direction rails A and B. The X-direction push system is then positioned to push the lid to a predetermined position or into a lid storage area.

[0051] The second Z-direction take-out arm 113 is slidably mounted on the drive rail C119, the drive electric cylinder C120 drives the drive rail C119, the second Z-direction take-out arm 113 includes a Z-direction drive electric cylinder D121, and the Z-direction drive electric cylinder D121 is provided with a lifter 11, which is driven to move up and down.

[0052] The multi-stage Z-direction take-out arm 11 is provided on the sample storage tank 2000. The process for using the multi-stage Z-direction take-out arm to take out the lid or basket from the sample storage tank is as follows: Z-direction drive sub-electric cylinder A115 and Z-direction drive sub-electric cylinder B116 drive the drive rail C119 to move downward, which causes the second Z-direction take-out arm 113 mounted on the drive rail C119 to move downward. Of course, the drive electric cylinder C can also drive the second Z-direction take-out arm to move laterally on the drive rail C so that the take-out member mounted on the second Z-direction take-out arm moves laterally to an appropriate position. After the first Z-direction take-out arm moves, a second Z-direction take-out arm is provided to enable further take-out. The second Z-direction take-out arm is moved downward in the Z direction by the drive electric cylinder D, which causes the lifter to move downward and take out the lid of the sample storage tank.

[0053] Two embodiments of the removal member are disclosed herein. In one embodiment, the removal member 111 is provided with a positive electromagnetic member, a negative magnetic member on the top surface of the lid, and a negative magnetic member on the top surface of the basket. To remove the lid, the removal member moves downward to the top surface of the lid, and the positive and negative electromagnetic members cooperate to allow the removal member to remove the lid. To release the lid, the positive electromagnetic member is de-energized, allowing the lid to be released. Similarly, the removal of the basket by the removal member is also achieved by the positive and negative electromagnetic members working together.

[0054] In a preferred embodiment of the removal member of this embodiment, the multi-stage Z-direction removal arm 11 further includes an X-arm (not shown), which is attached to the second Z-direction removal arm 113 and can raise and lower the X-arm along the Z axis. The removal member is attached to the X-arm and can move the removal member along the X axis. The lower end of the removal member is provided with removal handles 1112 extending on both sides. As shown in FIG. 11 , a receiving groove 1113 is provided on the upper end surface of the lid 4000, which receives the removal handle 1112 in the X-axis direction and can limit removal from the receiving groove 1113 in the Z-axis direction.

[0055] When the removal member 111 is driven or indirectly driven by the second Z-direction removal arm 113 to reach a position where it can remove the lid 4000, the removal handle 1112 at the bottom end of the removal member is on the same horizontal line as the receiving groove 1113 in the X-axis direction, and the X-arm drives the removal member, i.e., drives the removal handle 1112 to move in the X-axis direction, so that the removal handle 1112 enters the receiving groove 1113 in the X-axis direction. Furthermore, since the removal handle limits the receiving groove in the Z-axis direction, the removal handle removes the lid in the Z-axis direction. Of course, the removal process involves moving the lid upward by the second Z-direction removal arm and the first Z-direction drive arm, allowing lateral movement in the X-axis direction by the lateral drive receiving arm, and placing the removed lid at the target position.

[0056] In order to store or retrieve the lids effectively and rationalize an efficient and low-cost structure, in the present invention, the retrieval operation room is provided with an X-direction pushing system 12, which pushes the lids 4000 retrieved by the multi-stage Z-direction retrieval arm 11 to a predetermined position, and here, a design structure called a lid storage area 13 is disclosed for the predetermined position.

[0057] In the preferred X-direction push system 12 of this embodiment, the X-direction push system 12 includes an X-direction push member 121 and a lid storage area 13, and the X-direction push member 13 and the lid storage area 13 are arranged opposite each other. Here, "oppositely arranged" means that the arrangement positions of the X-direction push member 12 and the lid storage area 13 in the X-axis direction allow the X-direction push member 12 to push the lid 4000 or storage box 1000 removed by the removal member 111 into the lid storage area 13. Of course, here, the X-direction push member 121 may also be configured to push the lid removed by the removal member to a predetermined position. This is within the above scope as long as it is arranged so as not to interfere with opening the lid of the sample storage tank and removing the basket or storage box. Because the receiving and removal handle is not limited in the X-axis direction by the preferably provided receiving groove of the removal member, the X-direction push member of the X-direction push system does not need to be arranged in any other direction, as long as it is capable of pushing in the X-axis direction. In this way, costs and structural design space are significantly reduced.

[0058] In a further preferred embodiment of the X-direction pushing system 12 of this embodiment, the X-direction pushing system 12 includes an X-direction pushing member 121 and a lid storage area 13, and the X-direction pushing member 121 and the lid storage area 13 are respectively provided on both sides of the multi-stage Z-direction taking-out arm 11 in the X-axis direction, and the X-direction pushing member 121 can push the lid or storage box taken out by the taking-out member into the lid storage area or a predetermined position.

[0059] The X-direction push member 121 includes a push base holder 122, a push drive motor 123, an X-axis moving push plate 124, and a push guide rod 125. The push base holder 122 is fixed to the underside of one side of the multi-stage Z-direction take-out arm 11. The push drive motor 123 and the push guide rod 125 are fixed to the push base holder 122. The X-axis moving push plate 124 is driven by the push drive motor 123 to move along the push guide rod 125. The X-axis moving push plate 124 can move and extend from one side to the other side of the multi-stage Z-direction take-out arm 11, close to the lid storage area 13.

[0060] A receiving and storing opening 131 is provided on the side of the lid storing area 13 close to the X-axis moving pushing plate 124 .

[0061] When a cryotube needs to be removed from the sample storage tank 2000, the multi-stage Z-direction removal arm 11 uses the removal member to remove the lid 4000 to a position corresponding to the X-direction push member 121. The push drive motor 123 drives the X-axis moving push plate 124 to move it via the push guide rod 125. As a result, the X-axis moving push plate 124 penetrates downward from one side of the multi-stage Z-direction removal arm 11 and pushes the lid 4000 into the lid storage area 13 on the other side of the multi-stage Z-direction removal arm 11. Thus, the lid 4000 is pushed into the lid storage area 13. This not only removes and stores the lid, but also facilitates the removal of a basket or sample storage box from the sample storage tank by the multi-stage Z-direction removal arm. Of course, a receiving storage opening is opened on the side of the lid storage area closer to the X-axis moving push plate, so the lid is pushed into the lid storage area by the X-direction push member and then received from the receiving storage opening.

[0062] In addition to the multi-stage Z-direction take-out arm 11 and the X-direction pushing system 12, the system further includes a Y-direction receiving system 14. The provision of the Y-direction receiving system 14 allows for more efficient reception of storage boxes that have been transported directly or indirectly by a transfer box. In a preferred embodiment, the Y-direction receiving system 14 receives the storage box 1000 and transports the storage box 1000 to a corresponding position on the X-direction pushing system 12. The provision of the Y-direction receiving system 14 makes it possible to receive the storage box 1000 in the Y-axis direction, and also enables operation of the take-out operation chamber 1 in the Y-axis direction, facilitating reception of the storage box.

[0063] In a further preferred embodiment of this embodiment, the Y-direction receiving system 14 includes a Y-direction rail 141, a Y-direction moving tray 142, and a box storage receiving channel 143, wherein the Y-direction rail 141 extends in the Y-axis direction and is arranged below the push base holder 122, the box storage receiving channel 143 is slidably arranged on the Y-direction rail 141, the box storage receiving channel 143 has a predetermined length in the X-axis direction, and the Y-direction moving tray 142 is slidably arranged on the box storage receiving channel 143 in the X-axis direction.

[0064] The Y-direction receiving system 14 further includes a box storage push member 15, which is arranged at a position corresponding to the box storage receiving channel 143 and can push the Y-direction moving tray 142 in the box storage receiving channel 143.

[0065] The box preservation push member 15 includes a box preservation push driving motor 151 and a box preservation push plate 152, the box preservation push driving motor 151 is provided on the lower end surface of the push base holder 122, the box preservation push plate 152 is slidably provided on the lower end surface of the push base holder 122, and the box preservation push driving motor 151 drives the box preservation push plate 152 to extend and retract in the X-axis direction.

[0066] In this embodiment, the Y-direction moving tray 142 receives the storage box 1000 that has been connected to the outside and transported. Here, a gripper 5000 may be provided in the removal operation chamber to grip the target storage box 1000 onto the Y-direction moving tray 142. Other gripping methods are also possible, but are not limited thereto. It is clear that when the Y-direction moving tray 142 receives the target storage box, a driving member is provided to drive the box storage receiving channel 143 for driving by the driving member, and this will not be described in detail here. The Y-direction moving tray 142 moves in the Y-axis direction by the box storage receiving channel 142, and the target storage box moves to a position corresponding to the box storage push member 15. The box storage push drive motor 151 of the box storage push member 15 drives the box storage push plate 152 to push the target storage box to a predetermined position in the X-axis direction.

[0067] Before the target storage box is pushed by the box storage push plate 152, the multi-stage Z-direction removal arm 11 removes the lid 4000 of the sample storage tank 2000, and the X-direction push system 12 pushes the lid 4000 into the lid storage area 13. The multi-stage Z-direction removal arm 11 then moves downward in a similar manner, causing the removal member 111 to move into the sample storage tank 2000 and remove the basket 3000. While the arrangement of the removal member has been described above, the upper end surface of the basket is also configured in accordance with the removal of the removal member. Preferably, the upper end surface of the basket is also configured without restriction in the X-axis direction. The structure and arrangement of the receiving groove 1113 for restricting the removal handle 1112 in the Z-axis direction are not described in detail here, as the removal process is the same as described above. The removal member removes the basket to a position corresponding to the box storage push member 15, and the box storage push drive motor 151 drives the box storage push plate 152, which moves in the X-axis direction and pushes the target storage box into the basket. As shown in FIG. 4 , the basket disclosed herein has multiple basket receiving trays 6 that can be received in the X-axis direction and are arranged vertically in an array, and the box storage push plate pushes the basket into the target basket receiving tray 6. Once the basket is received in the target basket receiving tray 6, the multi-stage Z-direction removal arm 11 lowers the basket to its initial state, thus achieving the purpose of storing the target storage box.

[0068] In a preferred embodiment of the box preservation push plate 15 of this embodiment, the box preservation push plate 15 includes a first box preservation push sub-plate 153, a second box preservation push sub-plate 154, and a box preservation push head 155. The upper end surface of the first box preservation push sub-plate 153 is slidably mounted on the lower end surface of the push base holder 122. One end of the first box preservation push sub-plate 153 and one end of the second box preservation push sub-plate 154 are fixed at a right angle, and the other end of the second box preservation push sub-plate 154 and the box preservation push head 155 are fixed at a right angle, so that the box preservation push plate 152 has an inverted "Z" shape. As described above, the X-direction push system 12 and the box preservation push member 15 are rationally arranged to be compact in structure, which is more convenient for the pushing operation of the X-direction push system 12 and the box preservation push member 15.

[0069] In this embodiment, in a further preferred embodiment of the Y-direction receiving system 14, the Y-direction receiving system 14 includes a Y-direction drive motor 144, a Y-direction rotation shaft screw 145, and a box storage receiving channel receiving nut 146, the Y-direction drive motor 144 rotatably drives one end of the Y-direction rotation shaft screw 145, and the other end of the Y-direction rotation shaft screw 145 is rotatably mounted on an end of the Y-direction rail 141 away from the push base holder 122, The box storage receiving channel receiving nut 146 is fixed to one end of the box storage receiving channel 143, and the Y-direction rotation shaft screw 145 is engaged with the box storage receiving channel receiving nut 146; The Y-direction drive motor is drivably installed below the connection point between the first box storage push sub-plate and the second box storage push sub-plate, and the box storage receiving channel can be moved to a position corresponding to the box storage push head.

[0070] The Y-direction drive motor 144 rotates the Y-direction rotary shaft screw 145, so that the box storage receiving channel receiving nut 146 moves linearly in the Y-axis direction along the Y-direction rotary shaft screw 145, and the Y box storage receiving channel 143 moves linearly in the Y-axis direction. In this way, the Y-direction moving tray 142 receives the target storage box and moves it in the Y direction to the corresponding position of the box storage push head 155, and the storage box is pushed into the basket by the box storage push head 155.

[0071] To further improve the stability of the low-temperature environment of the target storage box during removal, this embodiment preferably provides the following embodiment: The Y-direction receiving system 14 further includes a cryostat 16, which is disposed below the box storage receiving channel 143 or fixed to the lower end surface of the box storage receiving channel 143, has a receiving cavity therein, and a plurality of nitrogen inlet holes 161 are disposed on the upper end surface of the cryostat 16, which communicate with the receiving cavity, and the receiving cavity of the cryostat 16 is communicated with a nitrogen supply tube. The receiving cavity is disposed within the cryostat 16 and communicates with the nitrogen supply tube, so that the nitrogen supply tube supplies nitrogen to the receiving cavity of the cryostat 16. Because the nitrogen inlet holes are disposed, liquid nitrogen spills from the nitrogen inlet holes, continuously maintaining the low temperature of the box storage receiving channel 143.

[0072] In a more preferred embodiment of this embodiment, the cryostat is box-shaped, cylindrical, or hemispherical. The specific structure of the cryostat is not limited here. As shown in FIG. 2, the cryostat is a rectangular box, and the box storage receiving channel is provided in the rectangular box.

[0073] In this embodiment, preferably, an embodiment of a lid storage area is further disclosed, and the lid storage area 13 includes a lid storage case 132 and a lid storage drive member 133, and a receiving storage opening 131 is opened on a side of the lid storage case 132 close to the X-direction push member 121, and a lid removal opening 134 is opened on an end face of the lid storage case 132 close to the removal member, The lid storage drive member 133 can move the lid storage case 132 in the X-axis direction. In cooperation with the X-direction push system 12, the lid storage drive member moves the lid storage case in the X-axis direction to more stably receive the lid in the lid storage area.

[0074] Specifically, in a preferred embodiment of the lid storage drive member 133, the lid storage drive member 133 includes a storage drive base 135, a storage drive rail 136, and a storage drive rack 137; The storage drive base 135 is fixed within the removal operation chamber and is located below the other side of the multi-stage Z-direction removal arm 11, the storage drive rail 136 is provided on the storage drive base 135, and the storage drive rack 137 has one end slidably mounted on the storage drive rail 136 and the other end fixed to the lid storage case 132.

[0075] The storage drive base 135 is provided above the lid storage case 132, and a first storage sub-drive rail 138 and a second storage sub-drive rail 139 are provided symmetrically on both sides of the upper end surface of the storage drive base 135, respectively. On the upper end surface of the storage drive base 135, two rows of drive direction channels 1310 in the X-axis direction are provided on both sides outside the first storage sub-drive rail 138 and the second storage sub-drive rail 139, respectively. The storage drive rack 137 includes a storage drive sliding plate 1311, a first storage drive clamping plate 1312, and a second storage drive clamping plate 1313, and the storage drive sliding plate 1311 is slidably mounted on the first storage sub-drive rail 138 and the second storage sub-drive rail 139. The upper end of the first storage drive clamping plate is fixed vertically to one side of the storage drive sliding plate, and the lower end of the first storage drive clamping plate passes through the drive direction channel on one side and is fixed to the lid storage case. The upper end of the second storage drive clamping plate is fixed vertically to the other side of the storage drive sliding plate, and the lower end of the second storage drive clamping plate passes through the drive direction channel on the other side and is fixed to the lid storage case.

[0076] The storage drive base 135 is disposed above the lid storage case 132, allowing the lid storage case to be better connected to the X-axis pushing system. A storage drive motor is disposed on the storage drive base, and the storage drive motor drives the storage drive sliding plate to move in the X-axis direction, causing the first storage drive clamping plate and the second storage drive clamping plate to move in the X-axis direction, and the lid storage case to move in the X-axis direction. The upper end of the first storage drive clamping plate is fixed vertically to one side of the storage drive sliding plate, and the lower end of the first storage drive clamping plate passes through the drive direction channel on one side and is fixed to the lid storage case, making the overall structure compact and stable, improving the stability of the drive lid storage case, and further improving the cooperation between the X-axis pushing system and the lid removed by the removal member.

[0077] In a further preferred embodiment of this embodiment, the removal operation chamber 1 further includes a storage box return member 17, which is arranged opposite the box storage push plate 15, and which includes a return push plate 171, which is extendable and retractable along the X axis.

[0078] The storage box return member 17 includes a return member base plate 172 and a return member drive motor 173. The return member base plate 172 is provided below the lid storage case 132 at a position opposite the box storage push member 17, the return push plate 171 is driven by a return member drive motor 173 and is slidably provided on the return member base plate 172, and a return section 174 is provided on the side of the return push plate 171 closer to the box storage push head 155.

[0079] The process of removing a storage box from a sample storage tank will be further described below. First, the lid of the sample storage tank is removed and stored in the lid storage area using a multi-stage Z-direction removal arm and an X-direction push system. Next, the multi-stage Z-direction removal arm removes the basket to the target position, where the target position refers to removing the storage box storage stand of the target storage box linked to the basket to a position corresponding to the return unit. At this time, the return member drive motor moves the return push plate along the X-axis toward the target storage box, and the return unit pushes the target storage box onto the Y-direction moving tray. Of course, before this, the Y-direction moving tray moves to a position corresponding to the return unit of the storage box's return member. After receiving the target storage box, the Y-direction moving tray moves in the Y-axis direction through the box storage receiving channel to a position where it can be easily grasped by the gripper. The gripper then grasps the target storage box and transports it into the transfer box, which then moves the target storage box. When the target storage box is placed inside the transport box, the lid opening mechanism places the open box lid of the transport box on the transport box and seals it.

[0080] After the multi-stage Z-direction take-out arm and the box storage and return member work together to take out the target storage box, the multi-stage Z-direction take-out arm returns the basket to the sample storage tank and takes out and connects the lid of the sample storage tank. During the lid removal and connection process, a lid removal opening is opened on the end face of the lid storage case closest to the take-out member, that is, on the top end face of the lid storage case. When connecting the lid, the take-out member first moves to a position corresponding to the lid in the horizontal direction of the X-axis, that is, to a position where the take-out handle of the take-out member corresponds to the receiving groove of the lid in the horizontal direction of the X-axis. At this time, the lid storage drive member drives the lid storage case to move toward the take-out member, so that the lid of the lid storage case moves in the X-axis direction. When the take-out handle enters the receiving groove, the take-out member can take out the lid of the sample storage tank in the Z-axis direction. When the removal handle is engaged with the receiving groove, the lid storage drive member drives the lid storage case back along the forward path, and the removal member is driven by the multi-stage Z-direction removal arm to couple the lid to the sample storage tank, thus completing the process. Of course, the process of storing and removing the storage box also involves coupling the lid after the storage and removal are completed.

[0081] Example 2 In the prior art sample storage system, in terms of the storage and withdrawal process, the withdrawal structure of the sample storage tank is not reasonably designed, which is costly. In addition, multiple devices cannot be connected, making it impossible to realize an industrialized storage and withdrawal line from the sample library and ensuring the use of the cold chain throughout the industrialized storage and withdrawal line.

[0082] This embodiment provides an intelligent sample storage and removal system, which includes a transfer joint member 7, one of the removal operation chambers 1 described in the above embodiment 1, and a sample storage tank 2000, wherein the removal operation chamber 1 is sealed to the upper end of the sample storage tank 2000, and a sealing joint port 18 is provided in the removal operation chamber 1, and the transfer joint member 7 is provided on one side of the outside of the sample storage tank 2000, and the transfer joint member 7 can receive a transfer box 701 and drive the transfer box 701 to join the opening of the transfer box to the sealing joint port 18.

[0083] The operation process of the transfer structure of this embodiment is as follows: When a biological sample is removed from a sample storage tank, the cryotube containing the biological sample is placed in a storage box, which is then placed in a transfer box, and the storage box is transported using the transfer box. Because the transfer box itself has a cooling function, a low-temperature environment is maintained during this process. The transfer box is moved to the rotating joint, and the transfer joint is used to transport the transfer box, and the opening of the transfer box is joined to the sealing joint of the removal operation chamber. The removal operation chamber opens the transfer box in the removal operation chamber, and after opening, the target storage box is stored in the removal operation chamber. A sealing tape is provided at the sealing joint, and a sealing tape is provided at the opening of the transfer box, which can be joined to the sealing tape at the sealing joint. When these two are joined, a seal is achieved, ensuring a stable low-temperature environment.

[0084] Throughout this process, the target storage box is exposed to a low-temperature environment whether it is in the transfer box or in the unloading operation room with the lid open. Furthermore, the transfer joints are provided to facilitate the connection and unloading of multiple sample storage tanks, realizing an industrialized storage and unloading line and ensuring the use of a cold chain throughout the process.

[0085] The industrialized sample storage and extraction line is composed of multiple sample storage tanks, each equipped with the extraction operation room described in Example 1. Direct extraction, transfer, and direct storage and extraction throughout the entire industrialized line are performed in a very low-temperature environment, facilitating management and extraction of the industrialized line. It is also easy to connect two or more sample storage tanks. Considering the above-mentioned beneficial effects, a preferred embodiment of a transfer connection member 7 is provided in this example. The transfer connection member 7 includes a moving rail 702, a moving trolley 703, and a connection drive member 704. The moving rail 702 is installed on one side of the outer surface of the sample storage tank 2000, and the moving trolley 703 is installed on the moving rail 702, and the moving trolley 703 can move a transfer box along the moving rail 702. The connection drive member 7 can drive the transfer box to seal and connect the opening of the transfer box to the sealing joint. In this case, the connecting drive member drives the transfer box to seal and connect the opening of the transfer box to the sealing joint port, and the removal operation chamber is used to seal and remove the target storage box from the transfer box, thereby ensuring the use of the cold chain throughout the process. This eliminates the need for complex transfer joint members, and also eliminates the need for the entire transfer joint member to have a sealing structure, because when two or more sample storage tanks need to be connected, a transfer joint member is installed between them. This reliably ensures the use of the cold chain throughout the process.

[0086] In a more preferred embodiment of this embodiment, the moving rail 702 is C-shaped, U-shaped, or concave-shaped, as shown in Figure 3. Such a configuration facilitates direct removal or storage of the sample storage tank, and the moving rail is C-shaped, U-shaped, or concave-shaped, which facilitates the connection of two or more sample storage tanks.

[0087] In a more preferred embodiment of this embodiment, the joining drive member 704 includes a joining drive motor 705, a joining vertical rail 706, and a joining lifting frame 707, and the joining drive motor 705 drives the joining lifting frame 707 to move up and down along the joining vertical rail 706; The moving rail 702 is provided on the upper end of the connecting vertical rail 706, and both of them are provided in a T-shape or an inverted L-shape. One end of the moving rail 702 passes through the connecting lifting frame 707, The upper end of the joining lifting frame 707 is two free ends that are not connected, and a lifting support plate 708 is provided at each of the two free ends, and a lifting support plate 709 is provided between the two lifting support plates 708, and the transport box 701 can be placed or installed on the lifting support plate 709.

[0088] As shown in FIG. 5, in the initial state, the lifting support plate 709 is positioned to easily receive a transport box. When the transport box is moved and placed on the lifting support plate, the joining drive motor drives the joining lifting frame to rise along the joining vertical rail, thereby raising the lifting support plate and sealing the transport box to the sealing joint port of the unloading operation room. Here, the upper ends of the joining lifting frame are two unconnected free ends that are higher than the moving rails, making the lifting support plate higher than the moving rails. The lifting support plate is attached to lifting support plates at the two unconnected free ends, which support the lifting support plate vertically but do not limit the lifting support plate's movement on the moving rails by the moving trolley. If the transport box transported from outside is not suitable to be placed directly on the position corresponding to the joining lifting frame, a moving trolley can be used to move the lifting support plate to the appropriate position, and after placing the transport box on the lifting support plate, the moving trolley can be used to move the lifting support plate with the transport box on it to the two lifting receiving plates, and then the joining lifting frame can be used to perform the seal joining operation.

[0089] In a more preferred embodiment of this embodiment, the lifting support plate 709 is provided with a transfer box limiting plate 710, which can limit the position of the transfer box. In this configuration, the lifting support plate can receive the transfer box more accurately.

A power contact plate 804 is provided on the moving rail 702 at a position below the trolley base corresponding to the electrical connection board.

[0091] A trolley positioning post 805 is provided on the upper surface of the trolley base of the movable trolley, and a positioning hole corresponding to the trolley positioning post 805 is provided in the lifting support plate 709. When the movable trolley needs to be moved individually, the connecting drive motor raises the lifting support plate 709 a predetermined distance, causing the trolley positioning post to disengage from the positioning hole in the lifting support plate, and the movable trolley slides on the movable rail through the trolley slide slot, electrically connecting the electrical connection board electrically connected to the trolley battery at the bottom of the trolley base to the power contact plate. A power supply structure is connected to the power contact plate itself, so that the trolley battery is charged by the power contact plate.

[0092] In a more preferred embodiment of this embodiment, the moving trolley further includes a distance measuring sensor 806, a single-chip computer 807, a trolley motor 808, and a trolley wheel 809, and the distance measuring sensor 806 is provided on the lower end surface of the trolley base 8; The single-chip computer is electrically connected to the distance sensor and the trolley motor, and controls the distance sensor and the trolley motor. The trolley motor drives the trolley wheels to move along the moving rail. The distance sensor measures the position of the trolley movement and makes the trolley movement path more accurate. The trolley motor drives the trolley wheels to move on the moving rail, thereby realizing the movement of the trolley on the moving rail.

[0098] The lid-opening drive member drives the lid-opening small rod, one end of which is rotatably connected to the other end of the lid-opening large rod, and one end of which is rotatably connected to the lid-opening fixed base. Therefore, when the lid-opening drive member is driven, the lid-opening disk moves to the box lid of the transfer box, the lid-opening positioning rod attached to the lid-opening disk is inserted into the transfer box positioning hole, and the lid-opening electromagnetic positive member attracts the electromagnetic negative member of the box lid of the transfer box, thereby moving the lid-opening large rod and the lid-opening small rod to open the box lid of the transfer box. Of course, when the box lid of the transfer box needs to be connected to the transfer box by moving the lid-opening large rod and the lid-opening small rod, the power supply to the lid-opening electromagnetic positive member is turned off, and the box lid of the transfer box is released from the lid-opening electromagnetic member and connected.
