Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular, to an automatic lid opener. Background Art

[0002] A cryotube is a commonly used medical container in medical and laboratory scientific research. In the era of translational medicine, a large-scale biobank is being built to provide personalized diagnosis and precision treatment for each person. It is necessary to store biological samples at ultra-low temperature for a long time. Cryopreservation can keep biological tissues such as blood, stem cells, and immune cells alive for a long time. In order to make the cryotube have good sealing performance and meet the requirements of sealed preservation of biological samples, the cryotube also has a tube cap adapted to the tube body, and the tube cap and the tube body are usually connected by threads.

[0003] In the related art, an opening mechanism is used to open or close the tube cap of the cryotube. The opening mechanism includes a motor and a drive shaft. Each motor corresponds to a drive shaft, and each drive shaft can extend into the corresponding cryotube and disassemble the tube cap of the cryotube. Specifically, the opening mechanism moves to the position of the tube cap of the sample tube at the opening position, then clamps and rotates the tube cap, thereby unscrewing the tube cap and clamping the tube cap and moving it to the waiting position for waiting. The opened sample tube is transported to the sampling position by a transport device for sampling and then returns to the opening and closing position. Finally, the opening mechanism clamps the tube cap and moves it to the opening and closing position and screws the tube cap back onto the sample tube to close the cap.

[0004] However, the opening mechanism in the related art needs to process a large number of cryotubes at one time, resulting in a large number of motors and drive shafts in the opening mechanism. Each cryotube needs to be provided with a motor and a drive shaft respectively to achieve the opening or closing operation, resulting in a complex structure for controlling multiple motors and unable to achieve automatic control of the opening mechanism.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0037] As Figures 1 to 6As shown in the figure, an embodiment of the present invention provides an automatic lid-opening machine, which includes a base 10, a frame 20, a first moving member 30, a lid-opening assembly 40, and a lid-removing assembly 50. The frame 20 is disposed on the base 10 and extends along a first direction. The first moving member 30 is movably disposed on the frame 20 along the first direction. The lid-opening assembly 40 includes a support frame 41, a first driving member 42, a first transmission unit 43, multiple groups of second transmission units 44, and multiple torque connectors 45 disposed on the support frame 41. The first transmission unit 43 includes multiple first transmission members 431. Each group of second transmission units 44 includes multiple second transmission members 441. The first driving member 42 is drivingly connected to the multiple first transmission members 431. Each first transmission member 431 is respectively drivingly connected to the multiple second transmission members 441 of a group of second transmission units 44. Each second transmission member 441 is correspondingly connected to a torque connector 45. The torque connector 45 has a lid-opening head. The lid-removing assembly 50 is disposed on the support frame 41. The lid-removing assembly 50 includes a second driving member 51 and a push plate 52. The second driving member 51 is drivingly connected to the push plate 52 to drive the push plate 52 to move along the first direction. The lid-opening head passes through the push plate 52.

[0038] Apply the automatic lid opener provided in this embodiment. The automatic lid opener includes a base 10, a frame 20, a first moving member 30, a lid opening assembly, and a lid retracting assembly 50. The frame 20 is disposed on the base 10 and extends in a first direction. The first moving assembly is movably disposed on the frame 20 along the first direction. The support frame 41 of the lid opening assembly is disposed on the first moving member 30, so that the lid opening assembly can be driven to move along the first direction under the action of the first moving member 30. The lid opening assembly includes a first driving member 42, a first transmission unit 43, multiple groups of second transmission units 44, and multiple torque connectors 45 disposed on the support frame 41. The first transmission unit 43 includes multiple first transmission members 431. Each group of second transmission units 44 includes multiple second transmission members 441. Since the first driving member 42 is drivingly connected to the multiple first transmission members 431, when the first driving member 42 operates, it can drive the multiple first transmission members 431 to transmit simultaneously. Since each first transmission member 431 can be drivingly connected to the multiple second transmission units 44, the first transmission member 431 can drive the multiple groups of second transmission members 441 to rotate simultaneously. And each group of second transmission units 44 is correspondingly connected to a torque connector 45. The opening head of the torque connector 45 is used to open or close the cap of the cryogenic tube. The first driving member 42 can drive the multiple first transmission units 43 to rotate and drive the multiple groups of second transmission units 44 to rotate. In this way, the first transmission unit 43 and the multiple groups of second transmission units 44 are used to achieve two-stage transmission, ensuring that the first driving member 42 can drive the multiple torque connectors 45 to open or close the caps, and ensuring that the lid opening assembly can open or close the caps of multiple cryogenic tubes. Specifically, when performing the lid opening operation, the lid opening assembly moves along the first direction under the action of the first moving member 30. In this way, the opening head of the torque connector 45 can cooperate with the cap of the cryogenic tube. Under the action of the first driving member 42, the first transmission unit 43, and the multiple groups of second transmission units 44, the multiple torque connectors 45 can be driven to rotate, ensuring the realization of the lid opening or closing operation. And, in order to ensure the separation of the opening head from the cap after closing the lid, a lid retracting assembly 50 is provided. The second driving member 51 is drivingly connected to the push plate 52 to drive the push plate 52 to move. In this way, after closing the lid, the push plate 52 moves downward, applying a force to the cap, and then the opening head can be separated from the cap, improving the degree of automatic control of the automatic lid opener.

[0039] It should be noted that part of the structure of the first moving member 30 is movably disposed on the frame 20 or all of the structure of the first moving member 30 is movably disposed on the frame 20.

[0040] Wherein, the first direction is the height direction of the frame 20, so that the first moving member 30 is movably disposed along the height direction of the frame 20.

[0041] As Figure 2 shown, the lid-opening assembly 40 further includes a first transmission gear 46 and a plurality of second transmission gears 47. The first driving member 42 is drivingly connected to the first transmission gear 46. The first transmission gear 46 is drivingly connected to a plurality of first transmission members 431 of the first transmission unit 43. Each first transmission member 431 is drivingly connected to a second transmission gear 47. Each second transmission gear 47 is respectively drivingly connected to a plurality of second transmission members 441 of a second transmission unit 44. With the above structure, by providing the first transmission gear 46 and the plurality of second transmission gears 47, and drivingly connecting the first driving member 42 to the first transmission gear 46, the first transmission gear 46 can be drivingly connected to a plurality of first transmission members 431. In this way, when the first transmission gear 46 rotates, it can drive a plurality of first transmission members 431 to rotate simultaneously. And each first transmission member 431 is drivingly connected to a second transmission gear 47, so that the first transmission member 431 can rotate synchronously with the second transmission gear 47. The second transmission gear 47 is drivingly connected to a plurality of second transmission members 441, so that the second transmission members 441 connected to the torque connector 45 rotate synchronously with the second transmission gear 47. Furthermore, it can be realized that the lid-opening assembly 40 drives a plurality of torque connectors 45 to rotate simultaneously to perform the operations of opening or closing the caps of a plurality of cryotubes. By means of the first transmission gear 46 and the plurality of second transmission gears 47, the lid-opening assembly 40 can perform two-stage transmission, ensuring the automatic control of the operations of opening or closing the caps of a plurality of cryotubes.

[0042] In this embodiment, both the first transmission member 431 and the second transmission member 441 are gears. With the above structure, by making both the first transmission member 431 and the second transmission member 441 be gears, it is convenient to mesh the first transmission member 431 with the first transmission gear 46 and mesh the second transmission member 441 with the second transmission gear 47, facilitating the realization of synchronous rotation.

[0043] As Figure 1 and Figure 2 shown, the lid-opening assembly 40 includes multiple groups of first transmission units 43, and each group of first transmission units 43 is provided with a first driving member 42. With the above structure, by providing multiple first transmission units 43 and corresponding multiple first driving members 42 for the multiple first transmission units 43, it is convenient to realize the driving control of the first transmission units 43.

[0044] As Figure 2 and Figure 3As shown, the torque connector 45 includes a sleeve 455, an open cap structure, an elastic member 454, and a rotating shaft 453. The sleeve 455 includes a first cylinder body 451 and a second cylinder body 452 that are rotatably connected. The first end of the first cylinder body 451 can be connected to the driving part. The first cylinder body 451 can move relative to the second cylinder body 452 along the axis. An over-torque structure 48 is provided at the connection between the first cylinder body 451 and the second cylinder body 452. The open cap structure is provided at the second end of the second cylinder body 452. The elastic member 454 is sleeved on the first cylinder body 451 and abuts against the first cylinder body 451. The first end of the rotating shaft 453 is engaged with the second transmission member. The second end of the rotating shaft 453 extends into the first cylinder body 451. The first end of the elastic member 454 abuts against the rotating shaft 453, and the second end of the elastic member 454 abuts against the first end of the first cylinder body 451.

[0045] With the above structure, the torque connector includes a sleeve 455, an open cap structure, and an elastic member 454. The first end of the first cylinder body 451 is connected to the driving part, so that the driving part can drive the first cylinder body 451 to rotate. An over-torque structure 48 is provided at the connection between the first cylinder body 451 and the second cylinder body 452, and an open cap structure is provided at the second end of the second cylinder body 452, so that the first cylinder body 451 and the second cylinder body 452 have an open cap state and a closed cap state of rotating together. When the operation of closing the cap of the cryopreservation tube is required, in order to avoid excessive torque causing damage to the cryopreservation tube, when closing the cap using the over-torque structure 48, the over-torque structure 48 can separate the first cylinder body 451 and the second cylinder body 452 when the force between the tube cap of the open cap structure and the cryopreservation tube reaches the maximum. In this way, when the rotating shaft 453 rotates and the open cap structure is used to perform the operation of closing the cap, it can prevent excessive torque from damaging the cryopreservation tube. Moreover, the elastic member 454 is sleeved on the first cylinder body 451 and abuts against the first cylinder body 451. At this time, the elastic member 454 is in a compressed state, so that the elastic member 454 exerts a downward force on the first cylinder body 451, causing the first cylinder body 451 to abut against the second cylinder body 452. In this way, it can be ensured that the first cylinder body 451 and the second cylinder body 452 rotate together, which is convenient for opening the cap of the cryopreservation tube and can also prevent the first cylinder body 451 from detaching from the torque connector. Furthermore, it can be ensured that the torque connector can be used to perform the operation of opening or closing the cap, which can not only improve the operation efficiency and achieve automatic control, but also avoid excessive torque during closing the cap from damaging the cryopreservation tube.

[0046] It should be noted that the over-torque structure 48 means that: during the process of opening the cap, the over-torque structure 48 does not function. During the process of closing the cap, if the torque between the first cylinder body 451 and the second cylinder body 452 is greater than the set value, the first cylinder body 451 and the second cylinder body 452 are separated; if the torque between the first cylinder body 451 and the second cylinder body 452 is less than the set value, the first cylinder body 451 and the second cylinder body 452 are connected.

[0047] Among them, by connecting the first end of the rotating shaft 453 to the driving part, the driving part can drive the rotating shaft 453 to rotate. The second end of the rotating shaft 453 extends into the first end of the first cylinder 451 and is in anti-rotation fit with the first cylinder 451, so that the first cylinder 451 can be driven to rotate synchronously. The first end of the elastic member 454 abuts against the rotating shaft 453, and the second end of the elastic member 454 abuts against the first cylinder 451, which is convenient for the elastic member 454 to cooperate with the first cylinder 451. Under the action of the over-torque structure 48, when the frozen tube needs to be opened, the first cylinder 451 and the second cylinder 452 rotate synchronously and play the role of opening the cover under the action of the opening structure. When the frozen tube needs to be closed, the first cylinder 451 and the second cylinder 452 rotate synchronously, and under the action of the over-torque structure 48, when the tube cap of the frozen tube is tightly closed, the first cylinder 451 is separated from the second cylinder 452, so that the second cylinder 452 does not rotate. Under the action of the force applied to the first cylinder 451 by compressing the elastic member 454, the first cylinder 451 does not separate from the second cylinder 452, which can play the role of closing the cover and avoid damage to the frozen tube.

[0048] As Figures 3 to 5 shown, the over-torque structure 48 includes a first gear 481 and a second gear 482. The first gear 481 is arranged on the second end of the first cylinder 451, and the first gear 481 is arranged along the circumferential direction of the first cylinder 451. The second gear 482 is arranged on the first end of the second cylinder 452, and the second gear 482 is arranged along the circumferential direction of the second cylinder 452. The first gear 481 and the second gear 482 are meshed with each other.

[0049] In this embodiment, the first set of teeth 481 has a plurality of first teeth protruding from the first cylinder 451. The first teeth include a first inclined side and a first vertical side. The first end of the first inclined side and the first end of the first vertical side are both connected to the first cylinder 451. The second end of the first inclined side is connected to the second end of the first vertical side. The second set of teeth 482 has a plurality of second teeth protruding from the second cylinder 452. The second teeth include a second inclined side and a second vertical side. The first end of the second inclined side and the first end of the second vertical side are connected. The second end of the second inclined side and the second end of the second vertical side are both connected to the second cylinder 452. The first inclined side is in contact with the second inclined side, and the first vertical side is in contact with the second vertical side. With the above structure, by providing a plurality of first teeth and a plurality of second teeth, the first inclined side of the first teeth is in contact with the second inclined side of the second teeth, and the first vertical side is in contact with the second vertical side. In this way, when opening the lid of the cryotube, the first cylinder 451 can rotate along the first direction, and the first vertical side abuts against the second vertical side, thereby driving the second cylinder 452 to rotate. When closing the lid of the cryotube, the first cylinder 451 rotates along the second direction, and the first inclined side abuts against and is in contact with the second inclined side. Since there is a force decomposition between the first inclined side and the second inclined side, the force between the first set of teeth 481 and the second set of teeth 482 is decomposed into a force upward along the inclined plane and a force tangent to the direction of motion. Since there is a force between the mouth of the cryotube and the tube cap, this force is greater than the force tangent to the direction of motion, that is, the force driving the rotation of the second cylinder 452. In this way, the first teeth of the first set of teeth 481 can move along the second teeth of the second set of teeth 482, causing the first cylinder 451 to separate from the second cylinder 452. However, due to the elastic force of the elastic member 454 of the torque connector, after the first cylinder 451 and the second cylinder 452 are separated, the elastic member 454 applies a downward force to continue to engage the first set of teeth 481 and the second set of teeth 482, thus preventing the first cylinder 451 from separating from the second cylinder 452.

[0050] In this embodiment, there is a first angle between the first inclined side and the first vertical side, and a second angle between the second inclined side and the second vertical side. Both the first angle and the second angle are acute angles. With the above structure, by setting both the first angle and the second angle as acute angles, it is convenient for the first cylinder 451 to separate from the second cylinder 452.

[0051] In this embodiment, a communication hole is provided on the second transmission member. The first end of the rotating shaft 453 passes through the communication hole and is in non-rotating fit with the communication hole. A clamping boss is provided on the rotating shaft 453, and the cross-sectional dimension of the clamping boss is larger than that of the communication hole. The clamping boss is clamped on the second transmission member.
