[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a cover opening device for accurately controlling and stably separating the cover of a cryopreservation tube, such as Figure 1-Figure 5 As shown, it includes an upper cover opening mechanism, which includes a brushless motor 1 and a transmission assembly 5. A cover removal mechanism 2 is installed at the bottom of the transmission assembly 5. The cover removal mechanism 2 includes a screw motor 21. The output shaft of the screw motor 21 is installed with a driving screw 23. A screw slider 24 is installed on the driving screw 23. Lifting rods 25 are installed at the bottom of both sides of the screw slider 24. A cover removal plate 27 is installed at the bottom of the lifting rod 25.

[0028] In this embodiment, the decapping mechanism 2 and the upper cover opening mechanism are fixed by a mounting base 3. The brushless motor 1 in the upper cover opening mechanism serves as a power source, providing a stable and lasting power output, thereby ensuring the smooth progress of the decapping operation. The transmission assembly 5 transmits the power of the brushless motor 1 to the decapping mechanism 2, thereby realizing the precise transmission and distribution of torque. The screw motor 21 in the decapping mechanism 2 drives the driving screw 23 to rotate, thereby driving the screw slider 24 to slide on the driving screw 23. The sliding of the screw slider 24 is converted into the lifting movement of the decapping plate 27 through the lifting rod 25, thereby realizing the precise control and stable separation of the cryopreservation tube cover. This design not only improves the decapping efficiency, but also ensures the stability and accuracy of the decapping process, and effectively avoids sample contamination and damage caused by human factors.

[0029] Specifically, a beam sensor 4 is installed at the bottom of the mounting seat 3. The present invention realizes accurate detection of the position of the cryopreservation tube. The beam sensor 4 can emit and receive light beams. When the cryopreservation tube is placed at the specified position, the light beam is blocked, and the sensor sends a signal, thereby triggering the opening operation. This design ensures that the opening device only operates on the correctly placed cryopreservation tube, thereby improving the accuracy and safety of the work.

[0030] Furthermore, the screw motor 21 is mounted on the mounting base 3 via a fixing plate 22. This design ensures the stability and reliability of the screw motor 21 during operation. The fixing plate 22 provides a solid support to prevent the motor from shifting due to vibration or external force, thereby ensuring the smooth rotation of the drive screw 23 and the accurate sliding of the screw slider 24.

[0031] Furthermore, the lifting rod 25 is connected to the mounting seat 3 via a linear bearing 26. This design enables the lifting rod 25 to maintain linear motion during the lifting process, reducing deviation and shaking. The linear bearing 26 provides a low-friction, high-precision guiding effect, ensuring the stability and accuracy of the cover removal plate 27 during the lifting process, thereby improving the cover opening effect.

[0032] Furthermore, the transmission assembly 5 includes a main shaft 51, an upper ratchet 55 is installed at the bottom end of the main shaft 51, a lower ratchet 56 is arranged at the bottom of the upper ratchet 55, a screwdriver 58 is installed at the bottom of the lower ratchet 56, and the upper ratchet 55 and the lower ratchet 56 cooperate with each other. The design of the transmission assembly 5 cleverly combines the main shaft 51, the upper ratchet 55, the lower ratchet 56 and the screwdriver 58 together to achieve the transmission and conversion of torque. The mutual cooperation of the upper ratchet 55 and the lower ratchet 56 enables the screwdriver 58 to accurately grasp and rotate the cryopreservation tube cover, thereby realizing the cover opening operation. This design ensures the stability and reliability of the cover opening process and improves work efficiency.

[0033] Furthermore, a limit sleeve 54 is provided on the upper part of the upper ratchet 55, and the limit sleeve 54 is slidably matched with the main shaft 51. A guide sleeve 57 is provided on the bottom of the lower ratchet 56, and the guide sleeve 57 is slidably matched with the main shaft 51. This design limits the sliding range of the upper ratchet 55 and the lower ratchet 56 on the main shaft 51, preventing them from being dislocated due to external forces. At the same time, the limit sleeve 54 and the guide sleeve 57 also provide a smooth guiding effect, reduce friction and wear, and extend the service life of the transmission component.

[0034] Furthermore, a driving gear 53 is installed on the upper part of the main shaft 51, and the driving gears 53 of the main shaft 51 are linked by the reversing gear 11, and the output shaft of the brushless motor 1 is rotatably connected to the top of one of the main shafts 51. This design enables the output torque of the brushless motor 1 to be evenly transmitted to each transmission component 5, ensuring that they work synchronously and coordinatedly. The introduction of the reversing gear 11 also realizes the reversing transmission of torque, so that the device can adapt to the requirements of opening the cover in different directions.

[0035] Furthermore, there are eight transmission assemblies 5, and the driving gears 53 of each adjacent transmission assembly 5 rotate through a reversing gear 11. This design enables the device to process multiple cryopreservation tubes at the same time, greatly improving the work efficiency. At the same time, the introduction of the reversing gear 11 enables each transmission assembly 5 to work closely and coordinately, ensuring the stability and accuracy of the opening process.

[0036] Furthermore, the top end of the main shaft 51 is mounted on the housing of the brushless motor 1 through a bearing 52. This design allows the main shaft 51 to remain stable and steady during rotation. The bearing 52 provides low-friction, high-precision support, reduces vibration and noise of the main shaft 51 during rotation, and thus improves the overall performance and service life of the device.

[0037] When the opening device for accurately controlling and stably separating the cryotube cover of the present invention is used, the device is first in an initial state, and all components are in a static or reset position. When the cryotube is placed in a specified position, the light beam emitted by the corresponding sensor 4 is blocked, and the sensor immediately sends a signal to trigger the opening operation.

[0038] The brushless motor 1, as a power source, starts working after receiving the signal from the sensor, and outputs stable and lasting power. The output torque of the brushless motor 1 is transmitted to the reversing gear 11 through the main shaft 51 and the driving gear 53 thereon, thereby realizing the linkage between the multiple transmission components 5. The reversing gear 11 not only transmits torque, but also realizes the reversal of torque, so that the device can adapt to the requirements of opening the cover in different directions.

[0039] The bottom end of the transmission assembly 5 is equipped with a decapping mechanism 2. When the torque is transmitted to the decapping mechanism 2, the screw motor 21 starts to work. The screw motor 21 drives the driving screw 23 to rotate, and the screw slider 24 on the driving screw 23 slides on the screw. The sliding motion of the screw slider 24 is converted into the lifting motion of the decapping plate 27 through the lifting rod 25, and the decapping plate 27 gradually approaches and contacts the cryopreservation tube cover.

[0040] Under the push of the lifting rod 25, the decapping plate 27 stably grasps the cryotube cover and lifts it upward to realize the decapping operation. During the decapping process, the upper ratchet 55 and the lower ratchet 56 cooperate with each other to ensure that the screwdriver 58 can accurately grasp and rotate the cryotube cover. The limit sleeve 54 and the guide sleeve 57 limit the sliding range of the upper ratchet 55 and the lower ratchet 56 on the main shaft 51, ensuring the stability and reliability of the decapping process. When the cryotube cover is fully opened, the decapping plate 27 returns to the initial position driven by the lifting rod 25, waiting for the next decapping operation.

[0041] Since there are eight transmission components 5 and each adjacent transmission component 5 is rotationally connected via a reversing gear 11, the device can process multiple cryopreservation tubes at the same time. When multiple channels are operated simultaneously, each transmission component 5 closely cooperates and works in coordination, ensuring the stability and accuracy of the opening process.

[0042] The device of the present invention can automatically detect the position of the cryopreservation tube and quickly start the opening operation after receiving the signal, which greatly improves the work efficiency and reduces the burden of manual operation. Through the precise coordination of the brushless motor, the transmission assembly and the cover removal mechanism, the cryopreservation tube cover is accurately controlled and stably separated, ensuring the stability and accuracy of the opening process. The device is designed with eight transmission assemblies, which can handle multiple cryopreservation tubes at the same time, further improving the work efficiency and ensuring the close coordination and coordination between the components when multiple channels are operated simultaneously.

[0043] The use of the through-beam sensor ensures that the device only operates on correctly placed cryopreserved tubes, avoiding the risk of misoperation and improving the safety and accuracy of work. Each component in the device has been carefully designed, such as the screw motor is installed on the mounting base through a fixed plate, ensuring stability and reliability during operation; the lifting rod is connected to the mounting base through a linear bearing, ensuring the stability and accuracy of the cover removal plate during lifting.

[0044] The design of the limit sleeve and guide sleeve limits the sliding range of the upper and lower ratchets on the main shaft, prevents dislocation, and provides a smooth guiding effect, reducing friction and wear, thereby extending the service life of the transmission component. The device can adapt to the needs of opening the cover in different directions, and the introduction of the reversing gear realizes the reversing transmission of torque, which enhances the adaptability and flexibility of the device.
