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

[0045] After the biological sample is taken out, it is stored in a biological sample cryotube, and a plurality of biological sample cryotubes are stored together in a storage box 1000, and the plurality of storage boxes 1000 are stored in a sample storage tank 2000 to be stored at a low temperature. A basket 3000 is provided in the sample storage tank 2000, and the plurality of storage boxes 1000 are stored in the basket 3000, which makes it easy to store and take out. The low-temperature environment of the conventional sample storage tank 2000 is provided by nitrogen supply, i.e., a liquid nitrogen tank. When taking out the cryotube of the biological sample in the sample storage tank 2000, first, the lid 4000 of the sample storage tank 2000 is opened, the storage box 1000 is taken out of the basket, the storage box 1000 is placed in a transfer box 701, and the storage box 1000 is transferred by the transfer box 701. Note that the sealing property of the lid 4000 is important, and a lid opening mechanism for taking out may be provided to ensure a low-temperature environment in the sample storage tank 2000. Then, open the sample storage tank to take out the basket 3000, and take out the target cryotube 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, which can unload the cryotube from the basket 3000 after unloading the sample storage tank 2000 in a sealed low-temperature environment and opening the cover 4000. This provides operation space in both the Z-axis and X-axis directions, and the unloading structure is reasonably designed, occupies little space, is low-cost, 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 enables movement of multiple distance sections in the Z-axis direction, the multi-stage Z-direction removal arm 11 is provided with a removal member 111, the multi-stage Z-direction removal arm 11 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 vertical, and will not be described in detail below) disclosed in the present invention may be a Z-direction manipulator or a Z-direction drive arm, and is not limited thereto. Any arm that realizes multi-section and multi-distance movement is within the scope of protection of the present 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, many three-axis manipulators are 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 provided on the first Z-direction take-out arm 112, and the first Z-direction take-out arm can move the lateral drive receiving arm in the Z-axis direction; the second Z-direction take-out arm 113 is provided on the lateral drive receiving arm 114, and the lateral drive receiving arm can move the second Z-direction take-out arm laterally in the X-direction; the take-out member 111 is provided on the second Z-direction take-out arm 113, and the second Z-direction take-out arm can move the take-out member up and down in the Z-axis direction. The first Z-direction take-out arm can move the lateral drive receiving arm in the vertical direction, which is the Z-direction, so that the second Z-direction take-out arm can move the operation movement part of the first Z-direction take-out arm vertically by the lateral drive receiving arm. The second Z-direction take-out arm itself has an operable vertical movement part in the Z-axis direction, so that two sections of the operation part are obtained in the vertical direction of the Z-axis, thereby greatly improving the operation depth and length in the vertical direction. 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-direction fetch arm to move in the X-direction. This design has a small occupied space, high stability and a large operating distance.

[0050] In order to cooperate well with the X-direction push system, this embodiment further discloses a more specific form of the multi-stage Z-direction take-out arm. That is, 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 rail A117 and the Z-direction rail B118 are fixed vertically and symmetrically in the Z-axis direction in the removal operation chamber 1, and both ends of the drive rail C119 are slidably mounted on the Z-direction rail A and the Z-direction rail B, respectively, and the Z-direction driving sub-electric cylinder A and the Z-direction driving sub-electric cylinder B move both ends of the drive rail C119 up and down, respectively. The Z-direction rail A117 and the Z-direction rail B118 are mounted symmetrically, and the space between the Z-direction rail A and the Z-direction rail B is the operation space of the X-direction push system 12, and thus the arrangement position of the X-direction push system 12 may be determined according to the removal member, making the structural design more reasonable. When the lid 4000 of the sample storage tank 2000 is removed by the removal member, the removal position is between the Z-direction rail A and the Z-direction rail B, and thus the lid is pushed to a predetermined position or a lid storage area according to the arrangement position of the X-direction push system.

[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 a lifter 11 is provided on the Z-direction drive electric cylinder D121, and the lifter 11 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, and the process of taking out the lid or basket of the sample storage tank using the multi-stage Z-direction take-out arm is as follows: The Z-direction driving sub-electric cylinder A115 and the Z-direction driving sub-electric cylinder B116 drive the driving rail C119 to move downward, so that the second Z-direction take-out arm 113 provided on the driving rail C119 moves downward. Of course, the driving electric cylinder C can also drive the second Z-direction take-out arm to move laterally on the driving rail C so that the take-out member provided on the second Z-direction take-out arm moves to an appropriate position in the lateral direction. After the first Z-direction take-out arm moves, a second Z-direction take-out arm is provided to enable further take-out, and the second Z-direction take-out arm moves downward in the Z direction by the driving electric cylinder D, so that the lifter moves downward to 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 an anode electromagnetic member, the lid top surface is provided with a cathode magnetic member, and the basket top surface is provided with a cathode magnetic member. When removing the lid, the removal member moves downward to the top surface of the lid, and the anode electromagnetic member and the cathode magnetic member work together to allow the removal member to remove the lid. To release the lid, the anode electromagnetic member is de-energized, allowing the lid to be released. Similarly, the removal of the basket by the removal member is also performed by the anode electromagnetic member and the cathode magnetic member 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 provided on the second Z-direction removal arm 113, which can raise and lower the X-arm along the Z axis, the removal member is provided on the X-arm, which can move the removal member along the X axis, and the lower end of the removal member is provided with removal handles 1112 extending on both sides, and 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 the removal handle 1112 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 the position for removing the lid 4000, the removal handle 1112 at the lower 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. Also, 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 is to move the lid upward by the second Z-direction removal arm and the first Z-direction drive arm, and enable the lateral movement in the X-axis direction by the lateral drive receiving arm, and place the removed lid at the target position.

[0056] In order to store or retrieve the lids well, and to rationalize an efficient and low-cost structure, in the present invention, the retrieval operation room is provided with an X-direction push 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 of 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 to each other. Here, "arranged opposite to each other" means that the arrangement position of the X-direction push member 12 and the arrangement position of the lid storage area 13 in the X-axis direction allow the X-direction push member 12 to push the lid 4000 or the storage box 1000 taken out by the take-out member 111 to the lid storage area 13. Of course, here, the X-direction push member 121 may push the lid taken out by the take-out member to a predetermined position. As long as it is arranged so as not to prevent the lid of the sample storage tank from being opened and the basket or the storage box from being taken out, it is within the above range. Since the receiving and taking-out handle is not limited in the X-axis direction by the receiving groove of the preferably arranged take-out member, the X-direction push member of the X-direction push system does not need to be arranged in other directions, and it is sufficient that it can be pushed in the X-axis direction. In this way, the cost and design space are significantly reduced.

[0058] In a further preferred embodiment of the 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, the X-direction push member 121 and the lid storage area 13 are respectively provided on both sides of the multi-stage Z-direction take-out arm 11 in the X-axis direction, and the X-direction push member 121 can push the lid or storage box taken out by the take-out member to 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 respectively 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, and 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 push plate 124 .

[0061] When it is necessary to take out the cryotube in the sample storage tank 2000, the multi-stage Z-direction take-out arm 11 takes out the lid 4000 to a position corresponding to the X-direction push member 121 by using the take-out member, and the push drive motor 123 drives the X-axis moving push plate 124 to move it by the push guide rod 125, so that the X-axis moving push plate 124 penetrates downward from one side of the multi-stage Z-direction take-out arm 11 and pushes the lid 4000 to the lid storage area 13 on the other side of the multi-stage Z-direction take-out arm 11, and thus the lid 4000 is pushed to the lid storage area 13. This allows the lid to be taken out and stored, and also facilitates the take-out of the basket or sample storage box in the sample storage tank by the multi-stage Z-direction take-out arm. Of course, since the receiving storage port is opened on the side of the lid storage area close to the X-axis moving push plate, the lid is pushed to the lid storage area by the X-direction push member and then received from the receiving storage port.

[0062] In addition to the multi-stage Z-direction take-out arm 11 and the X-direction push system 12, the Y-direction receiving system 14 is further included.

When the Y-direction moving tray 142 is received by the target storage box, a driving member is provided to drive the box storage receiving channel 143 for driving by the driving member, so that a detailed description is not given 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, and the box storage push driving 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 take-out arm 11 takes out 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, and then the multi-stage Z-direction take-out arm 11 moves downward by the same operation, so that the take-out member 111 moves into the sample storage tank 2000 to take out the basket 3000. The arrangement of the take-out member has been described above, but the upper end surface of the basket is also provided according to the take-out of the take-out member. Preferably, the upper end surface of the basket is also provided in the X-axis direction without any restriction. As for the structure and arrangement of the receiving groove 1113 for restricting the take-out handle 1112 in the Z-axis direction, the take-out process is the same as that described above, so it will not be described in detail here. The take-out member takes out 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 is a basket receiving tray 6 that can be received in the X-axis direction and is vertically arranged in an array, and the box storage push plate pushes the basket into the target basket receiving tray 6. When the basket is received in the target basket receiving tray 6, the multi-stage Z-direction take-out arm 11 lowers the basket to an initial state, thus achieving the purpose of storing the target storage box.

[0079] The process of removing the storage box from the 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 by using the multi-stage Z-direction removal arm and the X-direction push system. Next, the basket is removed to the target position by the multi-stage Z-direction removal arm, where the target position means removing the storage box storage stand of the target storage box linked to the basket to the position corresponding to the return unit. At this time, the return member drive motor moves the return push plate on the X-axis toward the target storage box, and the return unit pushes the target storage box to 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 return member of the storage box. When the Y-direction moving tray receives the target storage box, it moves in the Y-axis direction through the box storage receiving channel and moves to a position where it is easy to be gripped by the gripper, the gripper grips the target storage box and transports it into the transfer box, and the transfer box 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 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, takes out and connects the lid of the sample storage tank, and in the process of taking out and connecting the lid, a lid take-out port is opened on the end face of the lid storage case close to the take-out member, that is, a lid take-out port is opened on the upper end face of the lid storage case, so that 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, 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, and 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 take-out handle is engaged with the receiving groove, the lid storage driving member drives the lid storage case back along the forward path, and the take-out member is driven by the multi-stage Z-direction take-out arm to couple the lid with the sample storage tank, thus completing the process. Of course, the process of storing and taking out the storage box also includes the coupling of the lid after the storage and take-out are completed.

[0081] Example 2 In the prior art sample storage system, in terms of the storage and withdrawal process, the design of the withdrawal structure of the sample storage tank is not reasonable, the cost is high, and multiple instruments cannot be connected, the industrialized storage and withdrawal line from the sample library cannot be realized, and the use of the cold chain of the entire industrialized storage and withdrawal line cannot be ensured.

[0082] This embodiment provides an intelligent sample storage and removal system, which includes a transfer joint member 7, any 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, a seal joint port 18 is provided in the removal operation chamber 1, 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 seal joint port 18.

[0083] The operation process of the transfer structure of this embodiment is as follows. When a biological sample is taken out of one sample storage tank, the cryotube containing the biological sample is put into the storage box, then the storage box is put into the transfer box, and the storage box is transferred by the transfer box. Since the transfer box itself has a cold storage function, a low-temperature environment is also ensured in this process. The transfer box is moved to the rotating joint member, and the transfer joint member transfers the transfer box, and the opening of the transfer box is joined to the seal joint port of the take-out operation chamber. The take-out operation chamber opens the transfer box in the take-out operation chamber, and after opening the lid, the target storage box is stored in the take-out operation chamber. A seal joint port is provided at the seal joint port, and a seal tape of the opening of the transfer box is provided at the opening of the transfer box, which can be joined to the seal tape of the seal joint port to seal each other, and when these two are joined, a seal is realized and the stability of the low-temperature environment is ensured.

[0084] Throughout the 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. In addition, a transfer joint is provided to facilitate the joining and unloading of multiple sample storage tanks, realizing an industrialized storage and unloading line and ensuring the use of the cold chain throughout the process.

The joint driving member 7 can drive the transfer box to seal and join the opening of the transfer box to the sealing joint port. Here, the connecting drive member drives the transfer box to seal and connect the opening of the transfer box to the sealing joint port, and uses the removal operation chamber to seal and remove the target storage box in the transfer box, thereby ensuring the use of the cold chain throughout the process. Therefore, there is no need for a complex transfer joint member, and there is no 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 provided between them. This reliably ensures the use of the cold chain throughout the process.

Here, the upper ends of the joining lifting frame are two free ends that are not connected, and the free ends are higher than the moving rail, so that the lifting support plate is higher than the moving rail. The lifting support plate is provided on the lifting support plate at the two free ends that are not connected, and the two lifting support plates support the lifting support plate vertically but do not limit the movement of the lifting support plate on the moving rail 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, the moving trolley can be used to move the lifting support plate to the appropriate position, the transport box is placed on the lifting support plate, and then the moving trolley can be used to move the lifting support plate with the transport box placed on it to the two lifting receiving plates, and then the joining lifting frame can be used to perform the seal joining operation.
