Description

Technical Field

[0001] This utility model relates to a batch capping device for cryopreservation tubes, belonging to the field of cryopreservation tube processing technology. Background Technology

[0002] Cryopreservation tubes are containers used for cryopreserving biological samples (such as cells, tissues, bacteria, viruses, etc.). They are typically made of cryogenically resistant materials, such as polypropylene. Cryopreservation tubes can preserve samples for extended periods in ultra-low temperature environments such as liquid nitrogen, ensuring the samples' viability and stability. They are available in various sizes and capacities to meet different experimental needs. They are widely used in biomedical research, clinical testing, and other fields.

[0003] Currently, in low-temperature environments, the caps and bodies of cryovials may stick together due to condensation or sample leakage, making them difficult to open. This is especially true when hand strength is limited or unsuitable tools are used. Furthermore, many biological laboratories and biobanks store large quantities of cryovial samples. For example, large-scale cell culture experiments may require the simultaneous thawing of dozens or even hundreds of cryovials. Opening them one by one would be extremely time-consuming. For samples sensitive to time and environmental changes, failing to open them in batches could lead to inconsistencies due to excessively long opening intervals. Utility Model Content

This invention allows for the simultaneous opening of multiple cryovials in a short period of time, enabling rapid acquisition of the required samples and thus accelerating the experimental or testing process. Furthermore, it allows for the batch opening of a group of tissue sample cryovials, ensuring that all samples are exposed to the same environmental conditions at the same time, thereby better controlling experimental variables and making experimental results more comparable and accurate.

[0043] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a batch capping device for cryopreservation tubes, including an outer shell 1, a cryopreservation tube rack inlet and outlet 2 formed on the side of the outer shell 1, a central plate 3 provided inside the outer shell 1, and a cryopreservation tube rack drive clearance opening 4 formed at the bottom of the central plate 3; it also includes a cryopreservation tube rack inlet and outlet drive mechanism I, a capping lifting drive mechanism II, and a batch capping mechanism III for cryopreservation tubes.

[0045] The cryopreservation tube rack in / out drive mechanism I is located at the bottom inner side of the outer shell 1. The cryopreservation tube rack in / out drive mechanism I includes a cryopreservation tube rack tray 5, which passes through the cryopreservation tube rack drive clearance opening 4. A cryopreservation tube rack placement groove 6 is formed at the end of the cryopreservation tube rack tray 5. The cap lifting drive mechanism II includes a lifting drive motor 7 and a lifting slide rail 9. The lifting drive motor 7 is fixed on one side of the central plate 3, and the lifting slide rail 9 is fixed on the other side of the central plate 3.

[0046] The cryopreservation tube batch capping mechanism III is connected to the lifting slide rail 9 via the lifting slider 8. The cryopreservation tube rack entry and exit drive mechanism I transfers the cryopreservation tube rack in the cryopreservation tube rack placement slot 6 to the bottom of the cryopreservation tube batch capping mechanism III. The lifting drive motor 7 is also connected to the cryopreservation tube batch capping mechanism III via the lifting transmission belt (not shown). The lifting drive motor 7 drives the cryopreservation tube batch capping mechanism III to move up and down along the lifting slide rail 9 via the lifting transmission belt. The cryopreservation tube batch capping mechanism III moves downward to align with and unscrew the cryopreservation tube caps placed in the cryopreservation tube rack on the cryopreservation tube rack placement slot 6.

[0047] See Figure 3 , Figure 4 and Figure 5 In this embodiment, the cryopreservation tube rack entry and exit drive mechanism I further includes a cryopreservation tube rack entry and exit drive motor 10, a cryopreservation tube rack entry and exit drive rack 11, a cryopreservation tube rack entry and exit transmission slide rail 12, and a cryopreservation tube rack entry and exit transmission slider 13.

[0048] The cryopreservation tube rack in / out drive motor 10 is fixed to the side of the central plate 3, the cryopreservation tube rack in / out drive rack 11 is fixed to the bottom of the cryopreservation tube rack tray 5, and the drive end of the cryopreservation tube rack in / out drive motor 10 meshes with the cryopreservation tube rack in / out drive rack 11 through gears; the cryopreservation tube rack in / out transmission slide rail 12 is fixed to the bottom of the outer shell 1, and the cryopreservation tube rack in / out transmission slide rail 12 is connected to the cryopreservation tube rack tray 5 through the cryopreservation tube rack in / out transmission slider 13.

[0049] Specifically, the cryopreservation tube rack in / out drive motor 10 is fixed to the side of the central plate 3. The function of the cryopreservation tube rack in / out drive motor 10 is to provide power for the in / out movement of the cryopreservation tube rack by meshing the gear at the drive end with the cryopreservation tube rack in / out drive rack 11. The cryopreservation tube rack in / out drive rack 11 is fixed to the bottom of the cryopreservation tube rack tray 5, and the cryopreservation tube rack in / out transmission slide rail 12 is fixed to the bottom of the outer shell 1. It is connected to the cryopreservation tube rack tray 5 through the cryopreservation tube rack in / out transmission slider 13, which guides the in / out movement of the cryopreservation tube rack tray 5.

[0050] The cryopreservation tube rack tray 5 has a transmission clearance strip hole 14. The drive end of the cryopreservation tube rack entry and exit drive motor 10 passes through the transmission clearance strip hole 14 and then meshes with the cryopreservation tube rack entry and exit drive rack 11 through a gear. A clearance gap 15 is formed between the cryopreservation tube rack entry and exit drive motor 10 and the upper end face of the cryopreservation tube rack tray 5.

[0051] Specifically, the cryopreservation tube rack tray 5 has a transmission clearance slot 14. This design provides a channel for the drive end of the cryopreservation tube rack in / out drive motor 10 to mesh with the cryopreservation tube rack in / out drive rack 11. After the drive end of the cryopreservation tube rack in / out drive motor 10 passes through the transmission clearance slot 14, it meshes with the cryopreservation tube rack in / out drive rack 11 through gears, thereby driving the cryopreservation tube rack tray 5. The clearance gap 15 formed between the upper end face of the cryopreservation tube rack in / out drive motor 10 and the cryopreservation tube rack tray 5 prevents interference between the two cryopreservation tube rack trays during operation, ensuring the normal operation of the equipment.

[0052] See Figure 3 , Figure 4 and Figure 5 In this embodiment, the lifting drive motor 7 of the cap lifting drive mechanism II is a dual-shaft electric motor; the cap lifting drive mechanism II also includes a first transmission idler wheel 16, a first tension wheel 17, a second tension wheel 18, a second transmission idler wheel 19, and a transmission belt fixing seat 20; the first transmission idler wheel 16, the first tension wheel 17, and the second tension wheel 18 are all connected to the side of the central plate 3, and the second transmission idler wheel 19 is located at the bottom of the outer shell 1; one end of the lifting transmission belt is connected to the upper part of the transmission belt fixing seat 20, and the other end of the lifting transmission belt passes around the first transmission idler wheel 16, the first tension wheel 17, the drive wheel of the lifting drive motor 7, the second tension wheel 18, and the second transmission idler wheel 19 and then connects to the lower part of the transmission belt fixing seat 20.

[0053] Specifically, the lifting drive motor 7 of the capping and lifting drive mechanism II is a dual-shaft electric motor, providing power for the lifting and lowering of the cryopreservation tube batch capping mechanism III. The first transmission idler wheel 16, the first tensioning wheel 17, and the second tensioning wheel 18 are connected to the side of the central plate 3, and the second transmission idler wheel 19 is located at the bottom of the outer shell 1. The reasonable positional distribution ensures the normal operation of the capping and lifting drive mechanism II. Among them, one end of the lifting transmission belt is connected to the upper part of the transmission belt fixing seat 20, and the other end passes around the first transmission idler wheel 16, the first tensioning wheel 17, the drive wheel of the lifting drive motor 7, the second tensioning wheel 18, and the second transmission idler wheel 19 before connecting to the lower part of the transmission belt fixing seat 20, forming a complete lifting transmission system.

[0054] See Figure 6 , Figure 7 , Figure 8 and Figure 9In this embodiment, the batch capping mechanism III for cryopreservation tubes includes a batch capping mounting stand 21, a batch capping mounting top plate 22, a batch capping transmission support plate 23, a capping drive motor 24, and a capping assembly 25. The upper part of the batch capping mounting stand 21 is connected to the batch capping mounting top plate 22, the transmission belt fixing seat 20 is connected to the outer side of the top of the batch capping mounting stand 21, and the batch capping transmission support plate 23 is connected to the inner side of the middle part of the batch capping mounting stand 21, with the batch capping transmission support plate 23 located below the batch capping mounting stand 21. The capping drive motor 24 is located at the upper end of the batch capping mounting top plate 22. The capping drive motor 24 is connected to the capping assembly 25, which passes through the batch capping mounting top plate 22 and the batch capping transmission support plate 23.

[0055] Specifically, the capping drive motor 24 serves as the power source, generating rotational power when it starts. This power is transmitted to the capping assembly 25 via the motor shaft. Since the capping assembly 25 passes through the batch capping mounting top plate 22 and the batch capping transmission support plate 23, the rotational motion of the capping drive motor 24 can be effectively transmitted to all parts of the capping assembly 25, providing power for the capping operation. Specifically, the capping assembly 25 begins to rotate under the drive of the capping drive motor 24, and the batch capping mounting stand 21 provides a supporting structure for the entire capping process. The batch capping mounting top plate 22 connected to the upper part of the batch capping mounting stand 21 and the batch capping transmission support plate 23 connected to the inner side of the middle part together ensure that the capping assembly 25 rotates in a stable position.

[0056] See Figure 9 and Figure 10 In this embodiment, the capping assembly 25 includes a capping end gear 26, a gear drive shaft 27, a gear body 28, a clutch shaft 29, and a capping head 30. The capping end gear 26 meshes with the drive end gear of the capping drive motor 24. The upper end of the gear drive shaft 27 is connected to the capping end gear 26, and the lower part of the gear drive shaft 27 passes through the batch capping mounting top plate 22 and connects to the top of the gear body 28. The gear body 28 and the top clutch groove 31 of the clutch shaft 29 cooperate. The clutch shaft 29 passes through the batch capping transmission support plate 23, and the capping head 30 is connected to the lower end of the clutch shaft 29.

[0057] Specifically, the power of the cap-driving motor 24 is transmitted to the cap-end gear 26 in the cap-driving assembly 25 via the drive-end gear. This gear meshing method ensures efficient power transmission and allows for appropriate conversion of speed and torque. The cap-end gear 26 is connected to the upper end of the gear drive shaft 27, and the gear drive shaft 27 rotates when the cap-end gear 26 rotates. The lower part of the gear drive shaft 27 passes through the batch cap mounting top plate 22 and connects to the top of the gear body 28, thus transmitting power from the cap-end gear 26 above the top plate to the gear body 28.

[0058] The top clutch groove 31 of the gear body 28 and the clutch shaft 29 engages, enabling clutch control of the capping assembly 25 during operation. For example, when the capping head 30 needs to be replaced or the equipment needs to be debugged, the clutch structure can be controlled to disengage the capping head 30 from the power unit. The clutch shaft 29 passes through the batch capping transmission support plate 23, ensuring the stability of the clutch shaft 29 during rotation. The position of the clutch shaft 29 is accurately fixed in the support structure of the device.

[0059] Since the capping head 30 is connected to the lower end of the clutch shaft 29, when power is transmitted to the capping head 30, the capping head 30 can perform the capping operation on the cryovial cap. The specific structure of the capping head 30 can vary depending on the type and size of the cryovial cap. For example, for round cryovial caps, the capping head 30 has a groove that matches the edge of the cryovial cap or a rubber ring with high friction to ensure that it can effectively grip the cryovial cap.

[0060] In this embodiment, the number of capping assemblies 25 is M×N, where M is the number of columns and N is the number of rows; every four capping assemblies 25 are equipped with a capping drive motor 24, and the drive end gear of one capping drive motor 24 simultaneously meshes with the capping end gears 26 of four adjacent capping assemblies 25.

[0061] Specifically, the efficient power distribution is achieved by using one capping drive motor 24 to drive four adjacent capping assemblies 25. Through the meshing of the drive end gear and the four capping end gears 26, the rotational power of the capping drive motor 24 can be simultaneously transmitted to multiple capping assemblies 25. Similar to a central power source providing power to multiple surrounding work units, this reduces the number of capping drive motors 24 used, lowering equipment costs and energy consumption. The capping assemblies 25 are arranged in an M×N matrix, with one capping drive motor 24 configured for every four capping assemblies 25, resulting in a more compact and rational layout of the entire device. This layout allows for the placement of more capping assemblies 25 within a limited space, improving production efficiency. Here, M and N are positive integers and can be flexibly designed according to requirements.

[0062] Since one capping drive motor 24 drives four capping assemblies 25 simultaneously, as long as the rotational speed of the capping drive motor 24 is stable, the four capping assemblies 25 can rotate synchronously. This ensures that all capping assemblies 25 driven by the same capping drive motor 24 perform capping operations at the same speed and torque, thus improving the consistency of product quality.

[0063] See Figure 6 , Figure 7 and Figure 8In this embodiment, the batch capping mechanism III for cryopreservation tubes further includes a cap removal assembly 32. The cap removal assembly 32 includes a cap removal motor mounting plate 33, a cap removal drive motor 34, a first cap removal adapter plate 35, a second cap removal adapter plate 36, a cap removal plate body 37, and cap removal upper and lower guide rails 38. The cap removal motor mounting plate 33 is connected to the front of the batch capping mounting stand 21, and the cap removal drive motor 34 is connected to the cap removal motor mounting plate 33. The first cap removal adapter plate 35 is connected to the drive end of the cap removal drive motor 34, and the second cap removal adapter plate 36 is connected to the first cap removal adapter plate 35. The cap removal plate body 37 is connected to the lower end of the second cap removal adapter plate 36, and the capping head 30 is located below the cap removal plate body 37. The clutch shaft 29 passes through the cap removal plate body 37 and is inserted into the capping head 30. The cap removal upper and lower guide rails 38 are connected to the side of the batch capping mounting stand 21, and the second cap removal adapter plate 36 is connected to the cap removal upper and lower guide rails 38 through the cap removal upper and lower sliders 39.

[0064] Specifically, the cap removal motor mounting plate 33 is connected to the front of the batch capping mounting stand 21, providing a stable mounting base for the cap removal drive motor 34. This layout allows the cap removal drive motor 34 to be tightly integrated with the entire cryopreservation tube batch capping mechanism III, enhancing stability through the support structure of the batch capping mounting stand 21. The cap removal drive motor 34 is mounted on the cap removal motor mounting plate 33, providing power to the cap removal assembly 32. Starting from the drive end of the cap removal drive motor 34, power is transmitted sequentially through the first cap removal adapter plate 35 and the second cap removal adapter plate 36. The design of the first cap removal adapter plate 35 and the second cap removal adapter plate 36 helps to adjust the direction of power transmission, enabling the power to be accurately and effectively transmitted to the cap removal plate body 37.

[0065] The cap removal plate body 37 is connected to the lower end of the second cap removal adapter plate 36 and is positioned above the capping head 30. The clutch shaft 29 passes through the cap removal plate body 37 and is inserted into the capping head 30, creating conditions for the cap removal operation. When the cap removal drive motor 34 operates, it moves the cap removal plate body 37 via the first cap removal adapter plate 35 and the second cap removal adapter plate 36. The cap removal plate body 37 can apply force to the capping head 30 connected to the clutch shaft 29, thereby disengaging the capping head 30 from the cryopreservation tube cap and completing the cap removal function.

[0066] The cap removal guide rails 38 are connected to the side of the batch capping mounting stand 21, and the second cap removal adapter plate 36 is connected to it via the cap removal slider 39. This strictly limits the movement trajectory of the second cap removal adapter plate 36 and its connected components, ensuring that it can only move in the vertical direction. During the cap removal process, regardless of the power provided by the cap removal drive motor 34, the cap removal assembly 32 can move precisely up and down under the guidance of the cap removal guide rails 38, effectively avoiding swaying and deviation during movement, and greatly improving the stability and accuracy of the cap removal operation.

[0067] In summary, the cryopreservation tube rack in / out drive motor 10 of this utility model is fixed to the side of the central plate 3. The function of the cryopreservation tube rack in / out drive motor 10 is to provide power for the in / out movement of the cryopreservation tube rack by meshing the gear at the drive end with the cryopreservation tube rack in / out drive rack 11. The cryopreservation tube rack in / out drive rack 11 is fixed to the bottom of the cryopreservation tube rack tray 5, and the cryopreservation tube rack in / out transmission slide rail 12 is fixed to the bottom of the outer shell 1. It is connected to the cryopreservation tube rack tray 5 through the cryopreservation tube rack in / out transmission slider 13, which guides the in / out movement of the cryopreservation tube rack tray 5. The cryopreservation tube rack tray 5 has a transmission clearance strip hole 14. The drive end of the cryopreservation tube rack in / out drive motor 10 passes through the transmission clearance strip hole 14 and then meshes with the cryopreservation tube rack in / out drive rack 11 through the gear. A clearance gap 15 is formed between the cryopreservation tube rack in / out drive motor 10 and the upper end face of the cryopreservation tube rack tray 5. A transmission clearance slot 14 is formed on the cryopreservation tube rack tray 5. This design provides a channel for the drive end of the cryopreservation tube rack in / out drive motor 10 to mesh with the cryopreservation tube rack in / out drive rack 11. After the drive end of the cryopreservation tube rack in / out drive motor 10 passes through the transmission clearance slot 14, it meshes with the cryopreservation tube rack in / out drive rack 11 through gears to drive the cryopreservation tube rack tray 5. The clearance gap 15 formed between the upper end face of the cryopreservation tube rack in / out drive motor 10 and the cryopreservation tube rack tray 5 prevents interference between the cryopreservation tube rack tray 5 during operation and ensures the normal operation of the equipment. The lifting drive motor 7 of the capping lifting drive mechanism II is a dual-shaft electric motor, providing power for the lifting of the cryopreservation tube batch capping mechanism III. The first transmission idler wheel 16, the first tensioning wheel 17, and the second tensioning wheel 18 are connected to the side of the central plate 3, and the second transmission idler wheel 19 is located at the bottom of the outer shell 1. The reasonable positional distribution ensures the normal operation of the capping lifting drive mechanism II. The lifting transmission belt is connected at one end to the upper part of the transmission belt fixing seat 20, and at the other end, it passes over the first transmission idler pulley 16, the first tension pulley 17, the drive wheel of the lifting drive motor 7, the second tension pulley 18, and the second transmission idler pulley 19 before connecting to the lower part of the transmission belt fixing seat 20, forming a complete lifting transmission system. The capping drive motor 24 serves as the power source, generating rotational power when it starts. This power is transmitted to the capping assembly 25 via the motor shaft. Since the capping assembly 25 passes through the batch capping mounting top plate 22 and the batch capping transmission support plate 23, the rotational motion of the capping drive motor 24 can be effectively transmitted to all parts of the capping assembly 25, providing power for the capping operation. The capping assembly 25 begins to rotate under the drive of the capping drive motor 24, and the batch capping mounting stand 21 provides a support structure for the entire capping process. The batch capping mounting stand 21, with its upper part connected to the batch capping mounting top plate 22 and its inner middle part connected to the batch capping transmission support plate 23, together ensures that the capping assembly 25 rotates in a stable position. The power of the capping drive motor 24 is transmitted to the capping end gear 26 in the capping assembly 25 through the drive end gear.This gear meshing method ensures efficient power transmission and allows for appropriate conversion of speed and torque. The capping end gear 26 is connected to the upper end of the gear drive shaft 27. When the capping end gear 26 rotates, the gear drive shaft 27 also rotates. The lower part of the gear drive shaft 27 passes through the batch capping mounting top plate 22 and connects to the top of the gear body 28, thus transmitting power from the capping end gear 26 above the top plate to the gear body 28. The gear body 28 engages with the top clutch groove 31 of the clutch shaft 29. This clutch structure allows for clutch control of the capping assembly 25 during operation. For example, when it is necessary to replace the capping head 30 or perform equipment debugging, the capping head 30 can be separated from the power unit by controlling the clutch structure. The clutch shaft 29 passes through the batch capping transmission support plate 23, ensuring the stability of the clutch shaft 29 during rotation. The position of the clutch shaft 29 is accurately fixed in the support structure of the device. Since the capping head 30 is connected to the lower end of the clutch shaft 29, when power is transmitted to the capping head 30, the capping head 30 can perform the capping operation on the cryopreservation tube cap. The specific structure of the capping head 30 can vary depending on the type and size of the cryopreservation tube cap. For example, for round cryopreservation tube caps, the capping head 30 has a groove that matches the edge of the cryopreservation tube cap or a rubber ring with high friction to ensure that it can effectively grip the cryopreservation tube cap. The cap removal motor mounting plate 33 is connected to the front of the batch capping mounting stand 21, providing a stable mounting base for the cap removal drive motor 34. This layout allows the cap removal drive motor 34 to be tightly integrated with the entire cryopreservation tube batch capping mechanism III, and the stability is enhanced by the support structure of the batch capping mounting stand 21. The cap removal drive motor 34 is mounted on the cap removal motor mounting plate 33 and provides power to the cap removal assembly 32. Starting from the drive end of the cap removal drive motor 34, the power is transmitted sequentially through the first cap removal adapter plate 35 and the second cap removal adapter plate 36. The design of the first cap removal adapter plate 35 and the second cap removal adapter plate 36 helps to adjust the direction of power transmission, enabling power to be accurately and effectively transmitted to the cap removal plate body 37. The cap removal plate body 37 is connected to the lower end of the second cap removal adapter plate 36 and is positioned above the capping head 30. The clutch shaft 29 passes through the cap removal plate body 37 and is inserted into the capping head 30, creating conditions for the cap removal operation. When the cap removal drive motor 34 operates, it moves the cap removal plate body 37 through the first cap removal adapter plate 35 and the second cap removal adapter plate 36. The cap removal plate body 37 can apply force to the capping head 30 connected to the clutch shaft 29, thereby disengaging the capping head 30 from the cryopreservation tube cap and completing the cap removal function.This invention allows for the simultaneous opening of multiple cryovials in a short period of time, enabling rapid acquisition of the required samples and thus accelerating the experimental or testing process. Furthermore, it allows for the batch opening of a group of tissue sample cryovials, ensuring that all samples are exposed to the same environmental conditions at the same time, thereby better controlling experimental variables and making experimental results more comparable and accurate. This not only improves efficiency but also reduces errors caused by manual operation, making the entire experimental process more standardized and precise.

[0068] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
