Description

Technical Field

[0001] This utility model relates to the field of cryopreservation box transfer technology, and more specifically, to a cryopreservation box return device. Background Technology

[0002] In fields such as biological sample storage, it is often necessary to transfer samples from cryopreservation boxes at different temperature environments within a refrigerator. Automated refrigerators typically include a sample storage chamber at -80°C and a retrieval chamber at -20°C. During sample transfer, a robotic arm or similar gripping device places the cryopreservation box onto a transfer platform in the -20°C retrieval chamber. The transfer device then moves the cryopreservation box and sample into the -80°C sample storage chamber, where a robotic arm or similar device retrieves the sample for storage, thus completing the sample transfer operation.

[0003] However, currently, after the cryopreservation box is picked up and placed on the transfer platform, the placement of the cryopreservation box may be inaccurate, and there are no corresponding repositioning or correction measures. When the cryopreservation box enters the storage chamber at the next temperature, it will affect the accuracy of picking up the cryopreservation box, which may lead to unstable picking or damage to the sample on the cryopreservation box, seriously affecting the accuracy and effectiveness of cryopreservation box storage and retrieval.

[0004] Therefore, it is necessary to provide a cryogenic container return device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a cryopreservation box return device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cryopreservation container repositioning device, mounted on a support frame, is used to reposition cryopreservation containers on the transfer platform, including: A positioning slot is provided at the upper end of the transfer platform; A support is provided on the support frame, and a return plate and a drive mechanism are provided on the support. The drive mechanism is used to drive the return plate to move horizontally. A limiting mechanism, detachably mounted on the support frame and at least one such mechanism, is used to limit the distance the positioning plate moves in cooperation with the drive mechanism.

[0007] Furthermore, the drive mechanism includes: A driving component is mounted on the support, and a push plate is provided at the output end of the driving component. The push plate is detachably connected to the return plate.

[0008] Furthermore, the positioning plate is provided with a moving rod, and the push plate is provided with a through hole adapted to the moving rod; An elastic element is movably sleeved on the outside of the moving rod, and the elastic element is located between the return plate and the push plate.

[0009] Furthermore, the end of the moving rod away from the return plate passes through the through hole and is threadedly connected to a stop cylinder.

[0010] Furthermore, the limiting mechanism includes: A side frame is installed on the support, and a limit hole is provided on the side frame; A blocking component, disposed on the side frame, is used to limit the movement distance of the push plate.

[0011] Furthermore, the side wall of the push plate is provided with an extension rod that is slidably adapted to the limiting hole, and the end of the extension rod is provided with an inner groove.

[0012] Furthermore, the blocking component includes: Two upright plates are provided on both sides of the limiting hole, and a screw rod adapted to the inner groove is provided between the two upright plates. Two nut seats are threadedly connected to the screw rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this solution, the cryopreservation box is placed in the positioning slot on the transfer platform, which provides initial positioning. Then, the drive mechanism drives the return plate to move the cryopreservation box. The other side of the cryopreservation box is gradually blocked by the inner wall of the positioning slot until the entire side of the cryopreservation box is against the inner wall of the positioning slot. At this point, the return correction of the cryopreservation box is completed. This process corrects the problem of possible positional offset or angular deflection of the cryopreservation box on the transfer platform, ensuring the accuracy of the cryopreservation box's position on the transfer platform. This ensures that the cryopreservation box is not affected by the grasping accuracy after being transferred to the storage chamber at the next temperature, avoiding unstable grasping or sample damage caused by inaccurate positioning, and significantly improving the storage and retrieval accuracy of the cryopreservation box.

[0014] 2. When the drive mechanism moves the return plate, the limiting mechanism can restrict the movement distance of the return plate, so that the return plate moves within a safe range, avoiding the situation where the return plate exceeds the safe range and damages the cryopreservation box due to malfunctions or errors. It has good performance. In addition, the limiting range of the return plate by the limiting mechanism can be changed, and it can be adjusted according to different situations, making it more applicable.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 A cryopreservation box repositioning device, installed on the support frame 1, is used to reposition the cryopreservation boxes 3 on the transfer platform 2, and includes: Positioning slot 4 is located at the upper end of transfer platform 2; Support 5 is mounted on support frame 1. Support 5 is equipped with return plate 6 and drive mechanism 7. Drive mechanism 7 is used to drive return plate 6 to move horizontally. The limiting mechanism 8 is detachably mounted on the support frame 1 and at least one such mechanism is provided to limit the distance the return plate 6 moves in cooperation with the drive mechanism 7.

[0019] When in use, the cryopreservation box 3 is placed on the transfer platform 2 by a robotic arm or other equipment. At this time, the cryopreservation box 3 can be placed in the positioning slot 4, which can provide a preliminary positioning effect for the cryopreservation box 3 and is more conducive to the subsequent return operation of the cryopreservation box 3.

[0020] Then, the drive mechanism 7 starts and drives the positioning plate 6 to move horizontally towards the cryopreservation box 3. When the positioning plate 6 contacts the cryopreservation box 3, it continues to move, eventually pushing the cryopreservation box 3 to move. Finally, the other side of the cryopreservation box 3 will be blocked by the inner wall of the positioning groove 4 until the entire side of the cryopreservation box 3 is in contact with the inner wall of the positioning groove 4. At this time, the positioning correction of the cryopreservation box 3 is completed. In this process, the problem of positional offset or angular deflection of the cryopreservation box 3 on the transfer platform 2 is corrected, so that the position of the cryopreservation box 3 on the transfer platform 2 can be guaranteed to be accurate. This ensures that the accuracy of grasping the cryopreservation box 3 will not be affected after it is transferred to the storage chamber of the next temperature. It avoids the phenomenon of unstable grasping or sample damage caused by inaccurate position, significantly improves the storage and retrieval accuracy of the cryopreservation box 3, and has high practicality.

[0021] After the drive mechanism 7 moves the return plate 6 to return the cryopreservation box 3 to its original position, the drive mechanism 7 then moves the return plate 6 back away from the cryopreservation box 3, so as not to affect the subsequent transfer operation of the cryopreservation box 3.

[0022] When the drive mechanism 7 moves the return plate 6, the limiting mechanism 8 restricts the movement distance of the return plate 6. That is, the return plate 6 is stopped when it reaches the limit of the safe distance, ensuring that the return plate 6 moves within a safe range. This prevents malfunctions or errors from causing the return plate 6 to exceed the safe range and damage the cryopreservation box 3, thus improving the safety and stability of the return device when correcting the return of the cryopreservation box 3, resulting in good performance. Furthermore, the limiting range of the return plate 6 by the limiting mechanism 8 can be changed, allowing adjustment of the safe range of movement of the return plate 6 under different circumstances, thus broadening its applicability.

[0023] In this embodiment, preferably, please refer to [reference needed]. Figure 2-4 and Figure 6 The drive mechanism 7 includes: The drive unit 71 is mounted on the support 5. The output end of the drive unit 71 is provided with a push plate 72, which is detachably connected to the return plate 6.

[0024] Specifically, the driving component 71 in this application can be a cylinder or an electric telescopic cylinder, etc. The driving component 71 can extend or retract the push plate 72, that is, drive the push plate 72 to move horizontally, and the push plate 72 will drive the return plate 6 to move, thus realizing the extension and retraction operation of the return plate 6.

[0025] In this embodiment, preferably, please refer to [reference needed]. Figure 2-4 and Figure 6 The return plate 6 is provided with a moving rod 9, and the push plate 72 is provided with a through hole 10 that is adapted to the moving rod 9. An elastic element 11 is movably sleeved on the outside of the moving rod 9. The elastic element 11 is located between the return plate 6 and the push plate 72. The elastic element 11 in this application can be a spring.

[0026] With this design, when the return plate 6 is connected to the push plate 72, the moving rod 9 on the return plate 6 passes through the through hole 10 on the push plate 72, and at this time the elastic element 11 is located between the return plate 6 and the push plate 72.

[0027] Subsequently, when the push plate 72 moves the return plate 6, after the return plate 6 contacts the cryopreservation box 3, the push plate 72 continues to move. At this time, the return plate 6 and the elastic element 11 are compressed, and the elastic element 11 undergoes compression deformation, which can buffer part of the force transmitted from the push plate 72 to the return plate 6. This allows the return plate 6 to exert an elastic squeezing effect on the cryopreservation box 3, which can avoid the hard squeezing of the cryopreservation box 3 by the return plate 6, thus preventing damage to the cryopreservation box 3. This can better protect the cryopreservation box 3 and the samples on it, improve its service life and reduce damage.

[0028] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 6 The end of the moving rod 9 away from the return plate 6 passes through the through hole 10 and is threadedly connected to the stop cylinder 12.

[0029] With this design, when the moving rod 9 on the return plate 6 passes through the through hole 10 on the push plate 72, the stop cylinder 12 is screwed to the end of the moving rod 9, thereby limiting the moving rod 9 and preventing it from disengaging from the through hole 10, that is, preventing the return plate 6 from disengaging from the push plate 72.

[0030] Furthermore, by rotating the stop cylinder 12 to different positions on the moving rod 9, the position of the return plate 6 at the other end of the push plate 72 can be changed, thus changing the distance between the return plate 6 and the push plate 72. This allows the distance the return plate 6 can move to be adjusted without adjusting the parameters of the drive component 71. This can be adjusted according to the actual situation, making it more convenient for staff to operate, saving time and effort, and providing high flexibility and efficiency.

[0031] In addition, when the distance between the return plate 6 and the push plate 72 is adjusted, the initial state of the elastic element 11 will also change, thereby adjusting the buffering force of the return plate 6 on the cryopreservation box 3, which is highly flexible and has a good effect.

[0032] In this embodiment, preferably, please refer to [reference needed]. Figure 2-6 The limiting mechanism 8 includes: Side frame 81 is installed on support 5, and limit hole 82 is provided on side frame 81; The blocking component 83, located on the side frame 81, is used to limit the movement distance of the push plate 72.

[0033] Specifically, when installing the limiting mechanism 8, the side frame 81 is fixed to the support 5, and the driving component 71 drives the push plate 72 to move and return the cryopreservation box 3 to its original position. The blocking component 83 will block the push plate 72 to prevent it from moving outside the safe range due to failure or error, thus preventing the occurrence of larger failure accidents and improving the protection of the cryopreservation box 3.

[0034] Furthermore, the limiting range of the push plate 72 by the blocking component 83 can be changed, thereby adjusting the safe range of movement of the push plate 72 under different conditions, making it more widely applicable.

[0035] In this embodiment, preferably, please refer to [reference needed]. Figure 2-6 The side wall of the push plate 72 is provided with an extension rod 13 that is slidably adapted to the limiting hole 82, and the end of the extension rod 13 is provided with an inner groove 14.

[0036] Specifically, when installing the side frame 81, first ensure that the extension rod 13 passes through the limiting hole 82 of the side frame 81, such as... Figure 3-5 As shown in the figure, when the push plate 72 moves, it will drive the extension rod 13 to move along the limiting hole 82. The blocking component 83 will restrict the position of the extension rod 13, so that the extension rod 13 moves within a safe range, avoiding malfunction or damage to the cryopreservation box 3.

[0037] In this embodiment, preferably, please refer to [reference needed]. Figure 4-6 The blocking component 83 includes: Two upright plates 831 are located on both sides of the limiting hole 82. A screw 832 adapted to the inner groove 14 is provided between the two upright plates 831. Two nut seats 833 are threadedly connected to the screw 832.

[0038] Specifically, when the extension rod 13 passes through the limiting hole 82 of the side frame 81, the inner groove 14 of the extension rod 13 is simultaneously fitted onto the screw 832, and the extension rod 13 is positioned between the two nut seats 833. That is, the extension rod 13 will only move between the two nut seats 833, thus the forward and backward movement of the extension rod 13 is restricted by the two nut seats 833.

[0039] Furthermore, the position of the nut seat 833 on the screw 832 can be changed by rotating the nut seat 833, thereby changing the blocking position on the extension rod 13. It can be adjusted according to different situations, making it highly flexible.
