Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a turntable device and a method thereof. Background Art

[0002] A fuel cell is a power generation device that converts the chemical energy in a fuel directly into electrical energy through an electrochemical reaction. However, the voltage and output power that a single fuel cell (or fuel cell monomer) can provide are relatively low. In practical applications, multiple fuel cells are typically stacked together to form a fuel cell stack capable of achieving high voltage and high power output. Accordingly, a fuel cell stack is formed by stacking multiple fuel cell monomers together.

[0003] The fuel cell stack of a fuel cell needs to maintain structural stability during use to ensure that the fuel cell maintains a stable and continuous power output. The fuel cell stack of existing fuel cells is mostly fixed together by fastening means, such as screw fixing. However, when the fuel cell monomers stacked together are directly fixed together, it is easy to cause uneven force on various parts of the fuel cell stack. Uneven force on various parts of the fuel cell stack may affect the sealing performance and power transmission performance of the fuel cell stack, and ultimately affect the power output of the fuel cell stack. In addition, uneven force on various parts of the fuel cell stack may also cause the flow field plate of the fuel cell stack to deform due to excessive local force, and even cause damage to the proton exchange membrane, making the fuel cell stack unusable. Therefore, before being fixed, the existing fuel cell stack often needs to be pressed by a pressing machine so that the fuel cell monomers of the fuel cell stack are tightly stacked together to ensure the sealing performance of the fuel cell stack.

[0004] An existing fuel cell automatic stacking device generally includes a stacking mechanism, a removal mechanism, a manipulator and a control mechanism. The fuel cell automatic stacking device can move the stacking frame of the stacking mechanism through a guide rail set on a workbench, so that the tightening frame of the stacking frame of the stacking mechanism can be aligned with and press the fuel cell stack set on the mounting platform of the stacking mechanism, and then fix the compressed fuel cell stack together by screw fixing.

[0005] However, when the fuel cell automatic stacking device is fixed with screws, it is not only necessary to use professional tools (such as wrenches, etc.) to manually fix the compressed fuel cell stack together, resulting in low assembly efficiency and increased costs of the fuel cell stack; but in order to ensure the structural stability of the fuel cell stack, it is often necessary to use multiple pairs of screws to achieve the purpose of tightening, but this will aggravate the problem of uneven force because the tightening force of multiple screws is difficult to be consistent. In particular, once the tightening force of the same pair of screws is different, it is very easy to cause the fuel cell monomer to warp or deform, and the sealing performance of the fuel cell stack cannot be ensured. Summary of the Invention

[0006] An advantage of the present invention is that it provides a turntable device and method thereof, which can reduce the difficulty of bundling a fuel cell stack and help improve the assembly efficiency of the fuel cell stack.

[0007] Another advantage of the present invention is to provide a turntable device and method thereof, wherein, in one embodiment of the present invention, the turntable device can firmly bundle multiple compressed fuel cell monomers through bundling elements such as straps or ropes, so that each part of the fuel cell stack is evenly stressed.

[0009] Another advantage of the present invention is providing a turntable device and method thereof. In one embodiment of the present invention, the turntable device can be switched between a self-locking state and a free state to adapt to the specific needs of bundling fuel cell stacks. For example, when the drive device of the turntable device is not in operation, the turntable device is in the free state, allowing the reel to freely rotate forward to release the extended body of the bundling element. When the drive device of the turntable device is in operation, the turntable device is in the self-locking state, allowing the reel to rotate in the reverse direction under the drive device to reel in the extended body of the bundling element.

[0010] Another advantage of the present invention is that it provides a turntable device and method thereof, wherein, in order to achieve the above-mentioned objectives, the present invention does not require the use of expensive materials or complex structures. Therefore, the present invention successfully and effectively provides a solution that not only provides a simple turntable device and method thereof, but also increases the practicality and reliability of the turntable device and method thereof.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0060] In order to solve the problems or defects caused by the screw fixation of the existing fuel cell automatic stacking device, such as Figures 1 to 3 As shown, the present application provides an assembly line device for assembling a fuel cell stack, which can first stack a plurality of fuel cell monomers 801 into a fuel cell stack 800 at a stacking station through a stacking device 2; then transport the stacked fuel cell stack 800 to a bundling station through a conveying device 3; finally, after applying pressure to the fuel cell stack 800 to compact the plurality of fuel cell monomers through a bundling device 4, the fuel cell stack 800 is tightly bundled by a bundling element 70, so that each part of the fuel cell stack 800 is evenly stressed.

[0061] However, since the binding element 70 is typically implemented as a long strap, steel cord, or steel ribbon, and is typically wound onto a reel for use, when using the binding element 70 to tightly bind the fuel cell stack 800, it is necessary to first manually rotate the reel forward to partially release the binding element 70 so that it wraps around the fuel cell stack 800, and then manually rotate the reel backward to wind the binding element 70, thereby tightening the binding element 70 to tightly bind the fuel cell stack 800. However, this manual rotation of the reel to tighten the binding element 70 requires a significant amount of labor, increasing labor costs. Furthermore, due to limited manpower, it is difficult to tighten the binding element 70 to meet the requirements of binding the fuel cell stack 800. In particular, the binding element 70 is typically made of metal or alloy materials. Preferably, the bundling element 70 is made of a metal or alloy material with a yield strength of not less than 206 MPa, which makes it more difficult for the bundling element 70 to be tightened manually, which may easily cause the fuel cell stack 800 to be unable to be tightly bundled together by the bundling element 70 .

[0062] In order to increase the tension on the bundling element 70, the present application can directly mount the reel to a drive device, so that the drive device can drive the reel to rotate in the opposite direction to roll up the bundling element 70, thereby tightening the bundling element 70 to meet the bundling requirements of the fuel cell stack 800. However, since the drive device often restricts the reel from rotating in the forward direction, it is difficult for the reel to rotate in the forward direction and the bundling element 70 cannot be released, which brings great trouble and confusion to bundling the fuel cell stack. Therefore, to solve this problem, the present application creatively proposes a turntable device and method thereof, which are suitable for use in the above-mentioned production line equipment for assembling fuel cell stacks to replace the traditional reel.

[0063] Referring to the accompanying drawings of the present invention Figures 2 to 7B According to an embodiment of the present invention, a turntable device is illustrated, which is used to bundle a fuel cell stack 800 by means of a bundling element 70. Specifically, the turntable device 1 may include a driving device 10, a scroll 20 and a one-way lock assembly 30. The scroll 20 is used to releasably receive the bundling element 70. The one-way lock assembly 30 is drivably connected to the driving device 10, and the scroll 20 is correspondingly arranged on the one-way lock assembly 30, wherein when the one-way lock assembly 30 is not driven by the driving device 10, the scroll 20 is used to rotate forwardly under the action of an external force to release the bundling element 70, wherein when the one-way lock assembly 30 is driven by the driving device 10 to rotate in the reverse direction, the scroll 20 is used to rotate in the reverse direction driven by the one-way lock assembly 30 to receive the bundling element 70. It can be understood that the "forward" in the forward rotation mentioned in this application refers to the direction in which the bundling element 70 can be released (such as Figure 4A Accordingly, the reverse rotation mentioned in this application refers to the direction in which the strapping element 70 can be rolled (eg, Figure 4A Clockwise as shown).

[0064] It is worth noting that Figure 4A and Figure 4BAs shown, the binding element 70 of the present application may include a first end 71, a second end 72, and an extension body 73 extending between the first end 71 and the second end 72. The second end 72 of the binding element 70 serves as a connection end and is wrapped around the scroll 20, while the first end 71 of the binding element 70 serves as a free end. The extension body 73 of the binding element 70 is adapted to wrap around the fuel cell stack 800. Thus, when the first end 71 of the binding element 70 is pulled to rotate the scroll 20 in the forward direction, the extension body 73 of the binding element 70 is released to wrap around the fuel cell stack 800. When the one-way lock assembly 30 is driven by the driving device 10 to drive the scroll 20 in the reverse direction, the extension body 73 of the binding element 70 is rolled and retracted, tightening the extension body 73 wrapped around the fuel cell stack 800, so that the fuel cell stack 800 is tightly bound together by the extension body 73 of the binding element 70.

[0065] In other words, the turntable device 1 of the present application can be switched between a self-locking state and a free state to adapt to the specific needs of bundling the fuel cell stack 800. That is, when the one-way lock assembly 30 is not driven by the drive device 10 to remain stationary, the turntable device 1 is in the free state, i.e., the scrolling member 20 can freely rotate in the forward direction, so that by pulling the first end 71 of the bundling element 70, the scrolling member 20 can rotate in the forward direction to release the extension body 73 of the bundling element 70 so that the extension body 73 can be wrapped around the fuel cell stack 800. When the one-way lock assembly 30 is driven by the drive device 10 to rotate in the reverse direction, the turntable device 1 is in the self-locking state, i.e., the scrolling member 20 can be driven by the one-way lock assembly 30 to rotate in the reverse direction to roll the extension body 73 of the bundling element 70 so as to tighten the extension body 73 to tightly bundle the fuel cell stack 800.

[0066] More specifically, if Figures 5 to 7BAs shown, the one-way lock assembly 30 of the turntable device 1 of the present application may include a rotating shaft 31 relatively fixedly connected to the driving device 10, a sleeve member 32 relatively fixedly connected to the scroll member 20, and one or more locking members 33, wherein the sleeve member 32 is rotatably mounted on the rotating shaft 31, and the rotating shaft 31 has one or more self-locking grooves 310, wherein the one or more locking members 33 are respectively placed in the one or more self-locking grooves 310 of the rotating shaft 31, and each of the self-locking grooves 310 has a free position 3101 and a self-locking position 3102, wherein when the rotating shaft 31 is not driven by the driving device 10 to remain relatively stationary, each of the locking members 33 is in the free position 3101 of the corresponding self-locking groove 310, so that the sleeve member 32 can be relatively fixed to the rotating shaft 31. The axis of the rotating shaft 31 rotates freely in the forward direction, so that the rolling member 20 can also rotate freely in the forward direction relative to the axis of the rotating shaft 31 to release the extended body 73 of the bundling element 70; and when the rotating shaft 31 is driven by the driving device 10 to rotate in the reverse direction, each locking member 33 is driven by the rotating shaft 31 to rotate in the reverse direction around the axis of the rotating shaft 31 to generate centrifugal force, and each locking member 33 moves from the free position 3101 of the corresponding self-locking groove 310 to the self-locking position 3102 under the action of the centrifugal force to abut between the rotating shaft 31 and the sleeve member 32, so that the sleeve member 32 can rotate in the reverse direction with the rotating shaft 31, thereby driving the rolling member 20 to rotate in the reverse direction through the sleeve member 32 to roll the extended body 73 of the bundling element 70.

[0067] It is worth noting that when the driving device 10 stops driving the rotating shaft 31 so that the rotating shaft 31 stops rotating, the one or more locking members 33 will be relatively stationary with respect to the axis of the rotating shaft 31 without generating centrifugal force. At this time, each locking member 33 loses the centrifugal force and moves from the self-locking position 3102 to the free position 3101 to be accommodated in the self-locking groove 310 of the rotating shaft 31, so that the sleeve member 32 can still freely rotate in the positive direction relative to the axis of the rotating shaft 31, thereby allowing the rolling member 20 to also freely rotate in the positive direction relative to the axis of the rotating shaft 31 to release the extending body 73 of the bundling element 70.

[0068] Preferably, each of the self-locking grooves 310 has an inclined bottom surface 311, wherein the inclined bottom surface 311 of the self-locking groove 310 extends inwardly along the direction of the reverse rotation of the rotating shaft 31, so that the depth of the self-locking groove 310 gradually increases along the direction of the reverse rotation of the rotating shaft 31, that is, the inclined bottom surface 311 of the self-locking groove 310 gradually approaches the axis of the rotating shaft 31 along the direction of the reverse rotation of the rotating shaft 31, so that when the rotating shaft 31 is driven by the driving device 1 When the locking member 33 is driven to rotate in the opposite direction around the axis of the rotating shaft 31, the locking member 33 slides along the inclined bottom surface 311 under the action of its own centrifugal force to move away from the axis of the rotating shaft 31, so that the locking member 33 is pressed against between the sleeve member 32 and the inclined bottom surface 311 of the self-locking groove 310, thereby generating friction. As a result, the sleeve member 32 rotates in the opposite direction around the axis of the rotating shaft 31 under the action of the friction force, thereby driving the scrolling member 20 to rotate in the opposite direction.

[0069] In other words, the inclined bottom surface 311 of each self-locking groove 310 extends obliquely from the self-locking position 3102 to the free position 3101 along the direction of reverse rotation of the rotating shaft 31, and the depth of the self-locking groove 310 at the self-locking position 3102 is less than the depth of the self-locking groove 310 at the free position 3101, so that each locking member 33 moves from the free position 3101 of the corresponding self-locking groove 310 to the self-locking position 3102 under the action of centrifugal force to abut between the inclined bottom surface 311 of the self-locking groove 310 and the sleeve member 32.

[0070] For example, in one example of the present application, Figure 7A and Figure 7B As shown, the inclined bottom surface 311 of each self-locking groove 310 can be implemented as an inclined plane 3111 to ensure that the inclined bottom surface 311 of each self-locking groove 310 extends continuously and obliquely from the self-locking position 3102 to the free position 3101 along the direction of reverse rotation of the rotating shaft 31.

[0071] Of course, in another example of this application, Figure 8A and Figure 8B As shown, the inclined bottom surface 311 of each self-locking groove 310 can also be implemented as a concave curved surface 3112 to reduce the depth change of the self-locking groove 310 near the free position 3101, thereby helping to guide the locking member 33 to move from the free position 3101 to the self-locking position 3102 under the action of centrifugal force. It is understandable that the concave curved surface 3112 can be implemented as a circular curved surface or a non-circular curved surface, which will not be further described in this application.

[0072] It is worth mentioning that, according to the above embodiments of the present application, Figures 6 to 7B As shown, the locking member 33 of the one-way lock assembly 30 of the turntable device 1 can be but is not limited to having a cylindrical structure, wherein the diameter of the locking member 33 is smaller than the depth of the self-locking groove 310 in the free position 3101, and larger than the depth of the self-locking groove 310 in the self-locking position 3102. In this way, on the one hand, it can be ensured that when the locking member 33 is in the self-locking position 3102 of the self-locking groove 310, the locking member 33 can be pressed against the inclined bottom surface 311 of the self-locking groove 310 and the sleeve member 32, so as to drive the sleeve member 32 to rotate in the opposite direction through the rotating shaft 31 and the locking member 33, thereby driving the scrolling member 20 to rotate in the opposite direction around the axis of the rotating shaft 31; on the other hand, it can be ensured that when the locking member 33 is in the free position 3101 of the self-locking groove 310, the locking member 33 will not be clamped against between the sleeve member 32 and the inclined bottom surface 311, so that the sleeve member 32 can rotate freely relative to the axis of the rotating shaft 31, thereby ensuring that the scrolling member 20 can freely rotate in the positive direction around the axis of the rotating shaft 31.

[0073] Preferably, the plurality of self-locking grooves 310 in the one-way lock assembly 30 are axially symmetrically arranged on the outer periphery of the rotating shaft 31 .

[0074] More preferably, the inner diameter of the sleeve member 32 is slightly larger than the outer diameter of the rotating shaft 31, so as to ensure that the sleeve member 32 can be coaxially mounted on the rotating shaft 31 while avoiding the problem of shaking or swinging due to a large gap between the sleeve member 32 and the rotating shaft 31.

[0075] It is worth noting that since friction is inevitably generated between the rotating shaft 31, the sleeve member 32 and the locking member 33 due to their mutual movement, especially when the turntable device 1 is in the self-locking state, the locking member 33 relies entirely on friction to drive the sleeve member 32 to rotate in the opposite direction. Therefore, the rotating shaft 31, the sleeve member 32 and the locking member 33 of the present application can be made of, but are not limited to, materials with a certain hardness and rigidity such as steel or alloy, which helps to improve the service life of the turntable device 1.

[0076] According to the above embodiment of the present application, the driving device 10 can be implemented as, but not limited to, a device such as an electric motor or a motor capable of driving the rotating shaft 31 to rotate in the opposite direction. In addition, the rotating shaft 31 can be directly or indirectly mounted to the output shaft of the driving device 10, which will not be described in detail in this application.

[0077] In the above embodiments of the present application, Figure 4A and Figure 5As shown, the rolling member 20 of the turntable device 1 can be, but is not limited to, implemented as a reel 21 for rolling and storing the strapping element 70, wherein the reel 21 is relatively fixedly mounted to the sleeve member 32 of the one-way lock assembly 30 so that the reel 21 can rotate synchronously with the sleeve member 32.

[0078] Preferably, the reel 21 is detachably mounted to the sleeve member 32 of the one-way lock assembly 30, so that the reel 21 can be replaced as needed. For example, when the binding elements 70 on the reel 21 are all released, the empty reel 21 can be removed from the sleeve member 32 and the reel 21 with the binding elements 70 wound around it can be mounted on the sleeve member 32 to continue bundling the fuel cell stack 800 using the turntable device 1.

[0079] For example, Figure 7A and Figure 7B As shown, the outer peripheral wall of the sleeve member 32 of the one-way lock assembly 30 is provided with one or more limiting grooves 321, and the inner peripheral wall of the reel 21 is provided with one or more limiting blocks 211 that match the limiting grooves 321, wherein when the reel 21 is sleeved on the sleeve member 32, each limiting block 211 is embedded in the corresponding limiting groove 321, so that the reel 21 is relatively stationary with respect to the sleeve member 32, so that the reel 21 and the sleeve member 32 can rotate synchronously. Of course, in other examples of the present application, the positions of the limiting grooves 321 and the limiting blocks 211 can also be interchanged, or the reel 21 and the sleeve member 32 can be detachably fixed together by means such as screws, etc., which will not be described in detail in this application.

[0080] It is worth noting that, precisely because the reel 21 of the present application is relatively stationary with respect to the sleeve member 32, the reel 21 of the present application can be made of, but is not limited to, materials such as plastic, which helps to reduce the overall weight of the turntable device 1, thereby reducing the power consumption of the drive device 10. Of course, in other examples of the present application, the reel 21 and the sleeve member 32 can also be integrally connected, that is, the reel 21 and the sleeve member 32 can be integrally processed from materials such as steel or alloy.

[0081] Furthermore, in the above-described embodiment of the present application, the inclined bottom surface 311 of each self-locking groove 310 extends obliquely inward from the outer peripheral wall of the rotating shaft 31 along the direction of counter-rotation of the rotating shaft 31, thereby forming the self-locking groove 310 with a wedge-shaped structure. As a result, the starting depth of the self-locking groove 310 is much smaller than the diameter of the locking member 33 and cannot be utilized. However, in order to ensure that the ending depth of the self-locking groove 310 is greater than the diameter of the locking member 33 while preventing the depth of the self-locking groove 310 from varying too much, the inclined bottom surface 311 of the self-locking groove 310 must be sufficiently long. Therefore, it is difficult to provide more self-locking grooves 310 on the rotating shaft 31. The small number of self-locking grooves 310 can easily affect the operating stability of the one-way lock assembly 30, and thus the operating stability of the turntable device 1.

[0082] In order to solve the above problems, the attached Figure 9A and Figure 9B A first variant embodiment of the turntable device 1 according to the above-mentioned embodiment of the present application is shown. Compared to the above-mentioned embodiment of the present application, the turntable device 1 according to this variant embodiment of the present application is different in that the self-locking groove 310 of the rotating shaft 31 of the one-way lock assembly 30 has a front side 312 and a rear side 313, and the inclined bottom surface 311 of the self-locking groove 310 extends inwardly from the front side 312 to the rear side 313 along the direction of reverse rotation of the rotating shaft 31, forming the self-locking groove 310 with a trapezoidal structure. The starting depth of the self-locking groove 310 is close to the diameter of the locking element 33 to fully utilize the inclined bottom surface 311 of the self-locking groove 310, which helps to shorten the length of the inclined bottom surface 311 of the self-locking groove 310 so that as many self-locking grooves 310 as possible are provided on the rotating shaft 31, thereby improving the operating stability of the turntable device 1. It can be understood that the reverse rotation direction of the rotating shaft 31 in the present application refers to the direction from the front side 312 of the self-locking groove 310 to the rear side 313 of the self-locking groove 310 .

[0083] Preferably, the front side surface 312 and the rear side surface 313 of the self-locking groove 310 both extend along the radial direction of the rotating shaft 31, and the radial length of the front side surface 312 of the self-locking groove 310 is less than the diameter of the locking element 33, and the radial length of the rear side surface 313 of the self-locking groove 310 is greater than the diameter of the locking element 33, so that the length of the front side surface 312 of the self-locking groove 310 is equal to the starting depth of the self-locking groove 310, and the length of the rear side surface 313 of the self-locking groove 310 is equal to the ending depth of the self-locking groove 310. In other words, the free position 3101 of the self-locking groove 310 of the present application is located at a position adjacent to the rear side surface 313 of the self-locking groove 310, and the self-locking position 3102 of the self-locking groove 310 is located at a position adjacent to the front side surface 312 of the self-locking groove 310. In this way, when the locking member 33 is in the free position 3101 of the self-locking groove 310, the locking member 33 is completely accommodated in the self-locking groove 310 to prevent the locking member 33 from contacting the sleeve member 32 and generating unnecessary friction. When the locking member 33 moves to the self-locking position 3102 of the self-locking groove 310 under the action of centrifugal force, the locking member 33 is partially exposed outside the self-locking groove 310 to abut against the sleeve member 32 to generate friction, so that the sleeve member 32 rotates in the opposite direction around the axis of the rotating shaft 31 under the action of friction, thereby driving the scrolling member 20 to rotate in the opposite direction around the axis of the rotating shaft 31.

[0084] It is worth noting that when the driving device 10 drives the rotating shaft 31 to rotate in the opposite direction so that the locking member 33 is in the self-locking position 3102 of the self-locking groove 310, the locking member 33 is pressed between the sleeve member 32 and the rotating shaft 31. At this time, if the driving device 10 stops driving the rotating shaft 31 to rotate in the opposite direction, and pulls the bundling element 70 to make the rolling member 20 drive the sleeve member 32 to rotate forward, the locking member 33 will easily remain in the self-locking position 3102 of the self-locking groove 310 under the action of the friction force provided by the sleeve member 32, thereby preventing the rolling member 20 from rotating forward, thereby affecting the normal operation of the turntable device 1.

[0085] Therefore, in order to solve this problem, the attached Figures 10 to 11BA second variant embodiment of the turntable device 1 according to the above embodiment of the present application is shown. Compared to the above first variant embodiment of the present application, the turntable device 1 according to this variant embodiment of the present application is different in that: the one-way lock assembly 30 further includes one or more reset elements 34, wherein each reset element 34 is correspondingly arranged between the self-locking groove 310 and the lock element 33, and is used to provide a reset force to the lock element 33, so that the lock element 33 moves from the self-locking position 3102 of the self-locking groove 310 to the free position 3101 when the driving device 10 stops driving the rotating shaft 31 to rotate in the reverse direction, so as to prevent the lock element 33 from remaining in the self-locking position 3102 of the self-locking groove 310 when the driving device 10 stops driving, thereby ensuring the normal operation of the turntable device 1. It can be understood that the reset force provided by the reset element 34 for the lock 33 in the present application will not prevent the lock 33 from moving toward the self-locking position 3102 under the action of centrifugal force, that is, the lock 33 can move from the free position 3101 to the self-locking position 3102 under the action of centrifugal force.

[0086] More specifically, in an example of the present application, Figure 11A and Figure 11B As shown, the reset element 34 of the one-way lock assembly 30 can be implemented as an elastic element 341, wherein the elastic element 341 is correspondingly disposed between the front side surface 312 of the self-locking groove 310 and the lock element 33, and when the lock element 33 is in the self-locking position 3102 of the self-locking groove 310, the elastic element 341 elastically deforms (e.g., is compressed) to apply an elastic force to the lock element 33, so that the lock element 33 moves from the self-locking position 3102 of the self-locking groove 310 to the free position 3101 when the driving device 10 stops driving the rotating shaft 31 to rotate in the reverse direction. For example, in this example of the present application, the elastic element 341 can be implemented as, but is not limited to, a compression spring.

[0087] Of course, in another example of the present application, the elastic element 341 may be correspondingly disposed between the rear side surface 313 of the self-locking groove 310 and the locking element 33, and when the locking element 33 is in the self-locking position 3102 of the self-locking groove 310, the elastic element 341 elastically deforms (e.g., is stretched) to apply an elastic force to the locking element 33, so that the locking element 33 moves from the self-locking position 3102 of the self-locking groove 310 to the free position 3101 when the driving device 10 stops driving the rotating shaft 31 to rotate in the reverse direction. For example, in this example of the present application, the elastic element 341 may be, but is not limited to, implemented as a tension spring.

[0088] In addition, in other examples of the present application, the reset element 34 of the one-way lock assembly 30 can also be implemented as a magnetic element (not shown in the figure), so that the magnetic force (including magnetic attraction force or magnetic repulsion force) applied by the magnetic element to the lock member 33 serves as the reset force, and the lock member 33 can still move from the self-locking position 3102 of the self-locking slot 310 to the free position 3101 when the driving device 10 stops driving the rotating shaft 31 to rotate in the opposite direction.

[0089] According to another aspect of the present application, Figure 12 and Figure 13 As shown, the present application further provides a method for manufacturing a turntable device, specifically, as Figure 12 As shown, the manufacturing method of the turntable device may include the steps of:

[0092] S130: A scrolling member is correspondingly provided on the one-way lock assembly, wherein when the one-way lock assembly is not driven by the driving device, the scrolling member is used to rotate forward under the action of an external force to release the bundling element, and when the one-way lock assembly is driven by the driving device to rotate in the reverse direction, the scrolling member is used to rotate in the reverse direction driven by the one-way lock assembly to accommodate the bundling element.

[0093] It is worth noting that Figure 13 As shown, the step S110 of the manufacturing method of the turntable device of the present application may include the following steps:

[0094] S111: Disposing one or more self-locking grooves on the rotating shaft, wherein each self-locking groove has a free position and a self-locking position, and the rotating shaft is adapted to be relatively fixedly connected to the driving device;

[0095] S112: correspondingly disposing one or more locking elements in the corresponding self-locking grooves; and

[0096] S113: A sleeve member is rotatably mounted on the rotating shaft, wherein when the rotating shaft is not driven by the driving device to remain relatively stationary, each locking member is in the free position of the corresponding self-locking groove, so that the sleeve member can freely rotate in the positive direction relative to the axis of the rotating shaft, and when the rotating shaft is driven by the driving device to rotate in the reverse direction, each locking member is driven by the rotating shaft to generate centrifugal force, and moves from the free position to the self-locking position under the action of the centrifugal force to abut between the rotating shaft and the sleeve member, so that the sleeve member can rotate in the reverse direction with the rotating shaft.

[0097] According to another aspect of the present application, Figure 14 and Figure 15 As shown, the present application can further provide a method for using the turntable device. Specifically, as Figure 14 As shown, the method for using the turntable device may include the steps of:

[0098] S210: Pulling a bundling element releasably received in a rolling member so that the rolling member rotates forward to release the bundling element; and

[0099] S220: driving a one-way lock assembly to rotate in the reverse direction via a driving device, so that the rolling member rotates in the reverse direction driven by the one-way lock assembly to receive the binding element.

[0101] S221: driving a rotating shaft of the one-way lock assembly to rotate in the opposite direction by the driving device, wherein the rotating shaft has one or more self-locking slots, and each of the self-locking slots has a free position and a self-locking position;

[0102] S222: driving one or more locking members correspondingly disposed in the one or more self-locking grooves via the rotating shaft to generate centrifugal force;

[0103] S223: Under the action of the centrifugal force, each locking element is moved from the free position of the corresponding self-locking groove to the self-locking position to abut between the rotating shaft and the sleeve element; and

[0104] S224: Drive the sleeve member through each locking member to rotate in the opposite direction along with the rotating shaft.
