[0046] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.

[0048] As shown in Figures 1 to 4 The utility model discloses a canned pre-rotation machine which is used for canning liquid in cryopreservation tubes 10 and sealing the liquid in the cryopreservation tubes 10 by screw caps 11, comprising: a rack 2, which is provided with a liquid storage groove 20 and a centrifugal disc 21, the liquid storage groove 20 is used for storing liquid to be canned, and the centrifugal disc 21 is used for sequentially transferring a plurality of screw caps 11 to an output port in an open-down posture; a conveying mechanism 3, which is arranged on the rack 2, and a storage tray 1 is movably arranged on the conveying mechanism 3, a plurality of cryopreservation tubes 10 can be placed in the storage tray 1 at equal intervals, so that the conveying mechanism 3 can transfer the storage tray 1 to a preset position; a canning mechanism 4, which is arranged on the rack 2, and a canning pipe head 40 is movably arranged on the canning mechanism 4, the liquid in the liquid storage groove 20 can be sequentially filled into the plurality of cryopreservation tubes 10 through the canning pipe head 40; a pre-rotation mechanism 5, a locking mechanism 6 and a screwing mechanism 7, which are arranged on the rack 2, a first clamping jaw 50 is movably arranged on the pre-rotation mechanism 5, the first clamping jaw 50 is used for grabbing the screw cap 11 of the output port and pre-rotating the screw cap 11 on the pipe opening of the cryopreservation tube 10, a second clamping jaw 70 is movably arranged on the screwing mechanism 7, and the locking mechanism 6 is used for limiting the displacement of the cryopreservation tube 10 relative to the storage tray 1, so that the second clamping jaw 70 can tighten the screw cap 11 on the cryopreservation tube 10.

[0049] The present scheme is mainly to sequentially fill liquid into the cryopreservation tubes 10, and to seal the liquid by screwing the caps 11 onto the cryopreservation tubes 10. Specifically, a large liquid storage tank (not shown in the figure) is arranged outside the rack 2, and the liquid can be delivered into the liquid storage tank 20 by the control system. The design of the liquid storage tank 20 ensures that the liquid remains stable during the filling process, and can accommodate a sufficient amount of liquid to meet the batch filling requirements. When the worker or the robot places the storage tray 1 carrying several cryopreservation tubes 10 (without liquid) into the conveying mechanism 3, the filling tube head 40 will absorb the liquid from the liquid storage tank 20 according to the programmed height and angle, and align with the top of each cryopreservation tube 10 to inject the accurately measured liquid into each cryopreservation tube 10, which ensures the consistency and quality of the final product. During the above process, the centrifugal disc 21 can be pre-loaded with a suitable amount of caps 11, which are specially designed to ensure that the opening faces downward to facilitate subsequent grabbing and installation. After the liquid filling operation is completed, and the storage tray 1 is pushed by the conveying mechanism 3 to the lower side of the pre-rotation mechanism 5, the first clamping jaw 50 of the pre-rotation mechanism 5 accurately grabs the cap 11 from the output port of the centrifugal disc 21 and preliminarily rotates it onto the corresponding cryopreservation tube 10. As the conveying mechanism 3 further pushes the storage tray 1 to the lower side of the screwing mechanism 7, the locking mechanism 6 can be started to firmly fix the cryopreservation tube 10 on the storage tray 1, preventing any unnecessary movement during the subsequent tightening process. As the second clamping jaw 70 of the screwing mechanism 7 takes over, it applies appropriate torque to the cap 11 to tightly close the cryopreservation tube 10, which ensures the quality of the seal and prevents sample leakage or external contamination. The finally filled and sealed cryopreservation tube 10 is moved with the storage tray 1 to the next processing point or directly packed and stored. The entire process realizes the full automation of the filling and sealing process, significantly improves the production speed, reduces manual intervention, and reduces labor intensity. By accurately controlling the liquid injection amount and the pre-rotation and final tightening force of the cap 11, the quality consistency of each product is ensured, and the safety and reliability of sample preservation are enhanced.

[0050] The conveying mechanism 3 comprises: a first conveying module 30 arranged on the rack 2 and movable below the filling mechanism 4, the liquid storage tank 20 being detachably connected to the first conveying module 30, so that the storage tray 1 in the first conveying module 30 can approach or move away from the liquid storage tank 20; a receiving module 31 and a second conveying module 32, the receiving module 31 being located between the first conveying module 30 and the second conveying module 32, and being used to receive the storage tray 1 and the several cryopreservation tubes 10 filled with liquid thereon, and to move to the second conveying module 32 after the pre-rotation of the cap 11, so that the cap 11 is tightened by the screwing mechanism 7 and then moved to the outside of the rack 2 through the second conveying module 32.

[0051] As Figures 1 to 4 shown, the conveying mechanism 3 in the present embodiment is divided into three parts: a first conveying module 30, a receiving module 31, and a second conveying module 32. The first conveying module 30 is provided with detachable connection points, allowing the liquid storage tank 20 to be quickly installed and removed. This design facilitates maintenance and replacement of different types of liquid or cleaning and disinfection. During the bottling process, the first conveying module 30 can adjust the distance between the storage tray 1 and the liquid storage tank 20 as needed to ensure that the bottling pipe head 40 can accurately align with each cryogenic tube 10. The storage tray 1 and the cryogenic tubes 10 thereon after bottling are taken over by the receiving module 31, which is located between the first conveying module 30 and the second conveying module 32. Therefore, the receiving module 31 not only moves the cryogenic tubes 10 under the pre-rotation mechanism 5 so that the first gripper 50 can smoothly grasp the cap 11 and perform pre-rotation, but also needs to move the cryogenic tubes 10 with pre-rotated caps 11 to the second conveying module 32 so that the second gripper 70 of the screwing mechanism 7 can apply appropriate torque to completely tighten the cap 11. The design of the entire conveying mechanism 3 greatly reduces the need for manual intervention (all links from bottling to final sealing can be completed automatically), significantly improves work efficiency, and reduces the possibility of human error, preventing the risk of sample loss or contamination due to instability.

[0052] The first conveying module 30, the receiving module 31, and the second conveying module 32 each include: an installation platform 330 on which a fixed frame 331 is arranged; an axis 332 and a plurality of rotating wheels 333, which are rotatably arranged on the fixed frame 331, and a conveying belt 334 connected between the rotating wheels 333 and the axis 332; limiting blocks 335 symmetrically arranged on the fixed frame 331, so that when the storage tray 1 is placed on the conveying belt 334, the two side walls movably abut against the limiting blocks 335; a drive motor 336 arranged on the installation platform 330, and the output end of the drive motor 336 is driven by a belt to drive the conveying belt 334, so that the conveying belt 334 can drive the storage tray 1 to move in a specified direction.

[0053] Preferably, each conveying module (the first conveying module 30, the receiving module 31, and the second conveying module 32) in the embodiment has a similar design, including a mounting platform 330, a fixed frame 331, a rotating shaft 332, a rotating wheel 333, a conveying belt 334, a limiting block 335, and a driving motor 336, which ensures consistency and interchangeability between the modules, simplifying maintenance and operation; specifically, when the driving motor 336 is turned on, the output end thereof can drive the rotating shaft 332 to rotate through belt transmission, and because the conveying belt 334 is connected between the rotating shaft 332 and the rotating wheel 333, the movement switching of the storage tray 1 under the different modules can be realized through the conveying belt 334 in the process of power transmission. In this process, the design of the limiting block 335 ensures that the storage tray 1 always maintains the correct path and position during the entire conveying process, improving the accuracy of the canning and sealing; preferably, the rotating shaft 332 and the rotating wheels 333 in the embodiment can be rotatably arranged on the fixed frame 331 through bearings (not shown in the figure), ensuring that they can freely rotate with minimal friction; in addition, the conveying belt 334 is made of wear-resistant material and has a smooth surface, reducing the friction between the conveying belt 334 and the storage tray 1, so that the storage tray 1 can move smoothly in the specified direction, avoiding the occurrence of jamming.

[0054] The canning mechanism 4 includes a horizontal linear guide rail 41 arranged on the rack 2, a vertical linear guide rail 42 connected to the output end of the horizontal linear guide rail 80, and an installation bracket 420 connected to the output end of the vertical linear guide rail 42. An air pump 43 is detachably connected to the installation bracket 420, and a canning pipe head 40 is connected to the air pump 43 to adsorb the liquid in the liquid storage groove 20 and can it into the cryopreservation tube 10.

[0055] As Figure 1 and Figure 3As shown, when the worker or the robot places the storage tray 1 loaded with several cryopreservation tubes 10 on the conveying belt 334, the preparation for the filling operation can be started, at this time, the horizontal linear guide rail 41 drives the vertical linear guide rail 42 and the mounting bracket 420 thereon to approach the liquid storage tank 20 according to the program instructions, so as to ensure that the filling tube head 40 can reach above the liquid storage tank 20, thereby providing a guarantee for the accuracy and stability when the liquid is sucked; with the vertical linear guide rail 42 driving the mounting bracket 420 to move downward, the filling tube head 40 enters the liquid storage tank 20; at this time, the air pump 43 starts to suck a predetermined amount of liquid into the filling tube head 40 through the negative pressure effect, and after the suction is completed, the filling tube head 40 carrying the liquid leaves the liquid storage tank 20 through the cooperation of the vertical linear guide rail 42 and the horizontal linear guide rail 41, and the filling operation is completed under the condition that the filling tube head 40 and the cryopreservation tube 10 are aligned. As can be seen, the combination of horizontal and vertical linear guide rails 42 provides additional degrees of freedom, so that the filling tube head 40 can realize more fine position adjustment in sufficient space, further improving the precision in the filling process and reducing the occurrence of errors. Moreover, the transfer operation of the liquid can be automatically completed by the air pump 43 without manual intervention, greatly improving the work efficiency and reducing the possibility of human error.

[0056] The pre-rotation mechanism 5 and the screwing mechanism 7 each further comprise: a linear guide rail 80 horizontally mounted on the rack 2, an output end of the linear guide rail 80 being connected with a mounting frame 800; a driving member 81 and a lifting plate 82, the driving member 81 being arranged on the mounting frame 800, the mounting frame 800 being provided with a guide rail 83 in the vertical direction, a side wall of the lifting plate 82 being connected to an output end of the driving member 81, and a guide block 84 being mounted on the lifting plate 82 and movably connected to the guide rail 83; a rotating air cylinder 85 and a clamping air cylinder 86, the rotating air cylinder 85 being arranged on the lifting plate 82, an output end of the rotating air cylinder 85 being connected with the clamping air cylinder 86, the first clamping jaw 50 or the second clamping jaw 70 being arranged at an output end of the clamping air cylinder 86, so that the first clamping jaw 50 or the second clamping jaw 70 can grab the rotating cover 11 and drive it to rotate relative to the cryopreservation tube 10.

[0057] As Figure 1 and Figure 4As shown, the pre-rotation mechanism 5 and the screwing mechanism 7 in the embodiment both adopt the same structure and working principle, except that the operation steps to be achieved are different. Specifically, when the conveying belt 334 conveys a plurality of cryopreservation tubes 10 (including the storage tray 1) with liquid to the lower side of the pre-rotation mechanism 5, the first clamping jaw 50 can be used to grab the cap 11 of the output port of the centrifugal disc 21 and moved to the upper side of the cryopreservation tube 10 to be sealed, under the cooperation of the linear guide rail 80 and the driving member 81. When the driving member 81 is started again and pushes the lifting plate 82 to move downward along the guide rail 83, the clamping cylinder 86 and the first clamping jaw 50 on it can touch the cap 11 of the cryopreservation tube 10, and the rotation cylinder 85 can drive the rotation of the clamping cylinder 86 and the first clamping jaw 50, so that the cap 11 can be pre-rotated on the cryopreservation tube 10. This operation realizes the simple screwing of the cap 11 on the cryopreservation tube 10 (i.e. not completely tightened), which is beneficial to avoid misjudgment when the first clamping jaw 50 directly tightens the cap 11 (i.e. mistakenly thinking that there is still liquid leakage when tightening). Only after the locking structure fixes the cryopreservation tube 10, the screwing mechanism 7 with the same structure can be used to drive the second clamping jaw 70 to completely screw the cap 11 on the cryopreservation tube 10 after grabbing it. As can be seen, for the pre-rotation mechanism 5, the rotation angle is small, which ensures the preliminary fixation of the cap 11; for the screwing mechanism 7, a greater torque is applied to ensure that the cap 11 tightly seals the cryopreservation tube 10, thereby ensuring the high quality and consistency of the product.

[0058] The fixing frame 331 is also provided with a anti-falling cylinder 331a, and the output end of the anti-falling cylinder 331a is connected with an anti-falling plate 331b. The anti-falling plate 331b is used to prevent the storage tray 1 from falling off the conveying belt 334.

[0059] Further preferably, as shown in Figure 2 When the first conveying module 30 moves the cryopreservation tube 10 carrying liquid into the receiving module 31, the output end of the anti-falling cylinder 331a extends and lifts the anti-falling plate 331b to Figure 2 the right end of the receiving module 31, that is, the conveying belt 334 in the receiving module 31 can effectively limit the storage tray 1 from falling off the conveying belt 334 during the movement of the storage tray 1, and at the same time, the blocking force applied to the two sides of the storage tray 1 by the limiting block 335 can ensure that the storage tray 1 will not easily deviate from the track or fall off the conveying belt 334 even if it is subjected to vibration or uneven force during the conveying process, thereby greatly improving the stability of the equipment.

[0060] Further preferably, as shown in Figure 1 , Figure 2 and Figure 4As shown, the embodiment is also provided with at least three parallel driving line rails 23 on the rack 2, the output end of the driving line rail 23 is connected with a support plate, each support plate is provided with a mounting platform 330, therefore, the first conveying module 30, the receiving module 31 and the second conveying module 32 in the above can adjust the position according to the actual situation, reasonably use the overall layout in the rack 2, and enhance the flexibility of the pre-rotating machine.

[0061] Further preferably, the first conveying module 30, the receiving module 31 and the second conveying module 32 can be aligned or staggered between the two adjacent. In other words, the first conveying module 30 can be moved to a position away from the canning pipe head 40 by using the driving line rail 23, effectively avoiding the phenomenon of corrosion damage caused by the residual liquid dropping on the conveying belt 334, and being beneficial to prolong the service life of the module; and the receiving module 31 and the second conveying module 32 can adjust the relative position of the two in the rack 2 by relying on the driving line rail 23, so as to ensure that the pre-rotated cap 11 and the cryopreservation tube 10 can be stably and accurately transferred to the second conveying module 32, and the stable tightening operation of the cap 11 by the second clamping jaw 70 cooperating with the rotating cylinder 85 is ensured.

[0062] The locking mechanism 6 includes a clamping cylinder 60 and a locking block 61, and the rack 2 is provided with an extension plate 22, the clamping cylinder 60 is arranged on the extension plate 22 and symmetrically distributed on both sides of the second conveying module 32; the locking block 61 is connected to the output end of the clamping cylinder 60, and a locking groove 610 is formed on the locking block 61, and the two locking grooves 610 can be respectively movably attached to the outer wall of the cryopreservation tube 10 when they are close to each other.

[0063] Further preferably, as shown, Figure 4 When the storage tray 1 carrying the cryopreservation tube 10 filled with liquid is sent to the preset screwing station by the second conveying module 32, the control system sends a command to the clamping cylinder 60, and then pushes the locking block 61 to move towards the cryopreservation tube 10 through the output end, as the two symmetrically distributed locking blocks 61 approach each other, and the locking groove 610 on the locking block 61 accurately fits the outer wall of the cryopreservation tube 10, ensuring the close fit of the two, effectively limiting the displacement of the cryopreservation tube 10 in all directions, and providing protection for the smoothness and stability of the cap 11 when being tightened on the cryopreservation tube 10. Preferably, the embodiment can also add a lifting cylinder (not shown in the figure) on the basis of the above structure to lift the height of the clamping cylinder 60 and the locking block 61 in the vertical direction, so that the cryopreservation tube 10 can realize the tightening operation of the cap 11 without detaching from the storage tray 1, effectively preventing the phenomenon of the cryopreservation tube 10 being broken due to excessive force during the tightening process.

[0064] Further preferably, the embodiment is further provided with a liquid pumping device (not shown in the figure) on the rack 2, through which liquid in an external liquid storage tank (not shown in the figure) can be delivered into the liquid storage groove 20, and the whole operation process does not need manual intervention, which provides convenience for the tube head 40 to absorb liquid from the liquid storage groove 20, and improves the overall work efficiency.

[0065] It should be noted that the driving member 81 in the embodiment can be replaced by other driving devices such as a stepping motor and a servo motor. In addition, the structure and working principle of the centrifugal disc 21 in the embodiment are the same as those of the prior art, and will not be described here.
