Description

Rotary disc device

Technical Field

The utility model relates to the technical field of fuel cells, in particular to a turntable device.

Background

A fuel cell is a power generation device that directly converts chemical energy in fuel into electrical energy through an electrochemical reaction. However, a single fuel cell (or fuel cell) can provide a lower voltage and lower output power. In practical applications, a plurality of fuel cells are generally stacked together to form a fuel cell stack capable of achieving high voltage and high power output. Accordingly, a fuel cell stack of a fuel cell is formed by stacking a plurality of fuel cell cells together.

The fuel cell stack of the fuel cell needs to maintain stable structure during use so as to ensure that the fuel cell maintains stable and continuous power output. The fuel cell stack of the existing fuel cell is usually fixed together by fastening means, such as screw fixing, the fuel cell units of the stacked fuel cell stack. However, when the fuel cells stacked together simply are directly fixed together, uneven stress is easily applied to each part of the fuel cell stack. The uneven stress on each part of the fuel cell stack may affect the sealing performance and the power transmission performance of the fuel cell stack, and ultimately the power output of the fuel cell stack. In addition, the uneven stress on each part of the fuel cell stack may cause the flow field plate of the fuel cell stack to deform due to the local over-stress, and even cause the damage of the proton exchange membrane, which results in the failure of the fuel cell stack. Therefore, the conventional fuel cell stack often needs to be pressed by a pressing machine before being fixed, so that the fuel cells of the fuel cell stack are tightly stacked together to ensure the sealing performance of the fuel cell stack.

An existing fuel cell automatic stacking device generally includes a stacking mechanism, a moving-out mechanism, a manipulator and a control mechanism, and the fuel cell automatic stacking device can move through a guide rail arranged on a workbench through a stacking rack of the stacking mechanism, so that a tightening rack of the stacking mechanism can align with a fuel cell stack arranged on a mounting table of the stacking mechanism and compress the fuel cell stack arranged on the mounting table of the stacking mechanism, and the compressed fuel cell stack is fixed together in a screw fixing manner.

However, when the fuel cell automatic stacking device is fixed by the screw, the compressed fuel cell stack is fixed together by manual operation with a special tool (such as a wrench), which results in low assembly efficiency and high cost of the fuel cell stack; in addition, in order to ensure the structural stability of the fuel cell stack, it is often necessary to use a plurality of pairs of screws for fastening, but this will aggravate the problem of uneven stress due to the difficulty in matching the fastening forces of the plurality of screws, and in particular, if the fastening forces of the plurality of screws are different, the fuel cell unit will be easily warped or deformed, and the sealing performance of the fuel cell stack cannot be ensured.

In order to solve the problems or defects caused by the screw fixation of the existing fuel cell automatic stacking device, as shown in fig. 1 to 3, the present application provides a flow line device for assembling a fuel cell stack, which can stack a plurality of fuel cell units 801 into a fuel cell stack 800 at a stacking station by a stacking device 2; the stacked fuel cell stack 800 is conveyed to a bundling station through a conveying device 3; finally, after the fuel cell stack 800 is pressed to compress the plurality of fuel cells by the bundling device 4, the fuel cell stack 800 is tightly bundled by the bundling member 70, so that the parts of the fuel cell stack 800 are uniformly stressed.

However, since the binding member 70 is generally implemented as a long band, a wire rope or a wire rope, so that the binding member 70 is generally wound on a reel for use, when the fuel cell stack 800 is tightly bound using the binding member 70, it is necessary to manually rotate the reel forward to partially release the binding member 70 for encircling the fuel cell stack 800, and manually rotate the reel backward to roll the binding member 70 for tightening the binding member 70 to tightly bind the fuel cell stack 800. However, this reverse rotation of the reels by manual rotation to tension the strapping element 70 requires a significant amount of labor and results in increased labor costs, and the strapping element 7070 is difficult to tension due to limited manpower to meet the requirements for strapping the fuel cell stack 800. In particular, the strapping element 70 is typically made of a metal or alloy material. Preferably, the strapping element 70 is made of a metal or alloy material having a yield strength of not less than 206Mpa, which makes the strapping element 70 more difficult to artificially tighten, easily causing the fuel cell stack 800 to be unable to be tightly bundled together by the strapping element 70.

To increase the tightening force on the strapping element 70, the present application may mount the reel directly to a driving device to rotate the reel in reverse to roll the strapping element 70 by the driving of the driving device, thereby tightening the strapping element 70 to meet the strapping requirements of the fuel cell stack 800. However, since the driving device tends to limit the forward rotation of the reel, so that the reel is difficult to rotate in the forward direction and cannot release the binding element 70, which causes great trouble and trouble in binding the fuel cell stack, the present application inventively proposes a turntable device that is suitable for being applied to the above-mentioned assembly line equipment for assembling the fuel cell stack to replace the conventional reel.

Referring to fig. 2 through 7B of the drawings accompanying this specification, a carousel apparatus according to an embodiment of the present invention is illustrated for bundling a fuel cell stack 800 by a bundling element 70. Specifically, the turntable device 1 may include a driving device 10, a rolling member 20 and a one-way lock assembly 30. The rolling member 20 is adapted to releasably receive the strapping element 70. The one-way lock assembly 30 is drivably connected to the driving device 10, and the rolling member 20 is correspondingly disposed on the one-way lock assembly 30, wherein when the one-way lock assembly 30 is not driven by the driving device 10, the rolling member 20 is used for rotating in a forward direction under an external force to release the binding element 70, and when the one-way lock assembly 30 is driven by the driving device 10 to rotate in a reverse direction, the rolling member 20 is used for rotating in a reverse direction under the driving of the one-way lock assembly 30 to receive the binding element 70. It is to be understood that reference herein to "forward" in a forward rotation is to a direction (counterclockwise as viewed in fig. 4A) in which the strapping element 70 can be released; accordingly, references herein to "reverse" in reverse rotation refer to a direction (clockwise as viewed in fig. 4A) in which the strapping element 70 can be rolled.

It is noted that, as shown in fig. 4A and 4B, the banding 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, wherein the second end 72 of the banding element 70 is wound around the rolling member 20 as a connection end, and the first end 71 of the banding element 70 is a free end, wherein the extension body 73 of the banding element 70 is adapted to be wound around the fuel cell stack 800. Thus, when the first end 71 of the tying element 70 is pulled to rotate the rolling member 20 in the forward direction, the extension body 73 of the tying element 70 is released for winding the fuel cell stack 800; when the one-way lock assembly 30 is driven by the driving device 10 to rotate the rolling member 20 in a reverse direction, the extension body 73 of the strapping element 70 is rolled to be received for tightening the extension body 73 wound around the fuel cell stack 800, so that the fuel cell stack 800 is tightly bundled together by the extension body 73 of the strapping element 70.

In other words, the turntable device 1 of the present application can be switched between a self-locking state and a free state in order to adapt to the specific requirements of the bundled fuel cell stack 800. That is, when the one-way lock assembly 30 is not driven by the driving device 10 to remain stationary, the turntable device 1 is in the free state, i.e., the rolling member 20 can freely rotate forward, so that the rolling member 20 can be rotated forward by pulling the first end 71 of the strapping element 70 to release the extension body 73 of the strapping element 70, so as to wind the fuel cell stack 800 with the extension body 73; when the one-way lock assembly 30 is driven by the driving device 10 to rotate reversely, the rotary table apparatus 1 is in the self-locking state, that is, the rolling member 20 can be driven by the one-way lock assembly 30 to rotate reversely to roll the extension body 73 of the bundling element 70, so that the extension body 73 is tightened to tightly bundle the fuel cell stack 800.

More specifically, as shown in fig. 5 to 7B, 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 rolling member 20, and one or more locking members 33, wherein the sleeve member 32 is rotatably sleeved 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 disposed 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 be relatively stationary, each of the locking members 33 is disposed in the free position 3101 of the corresponding self-locking groove 310, such that the sleeve member 32 can freely rotate forward relative to the axis of the rotating shaft 31, so that the rolling member 20 is also free to rotate positively with respect to the axis of the rotating shaft 31 to release the extension body 73 of the tying element 70; when the rotating shaft 31 is driven to rotate reversely by the driving device 10, each of the locking pieces 33 is driven by the rotating shaft 31 to rotate reversely around the axis of the rotating shaft 31 to generate a centrifugal force, and each of the locking pieces 33 is moved from the free position 3101 of the corresponding self-locking groove 310 to the self-locking position 3102 to abut between the rotating shaft 31 and the sleeve member 32 by the centrifugal force, so that the sleeve member 32 can rotate reversely with the rotating shaft 31, thereby driving the rolling member 20 to rotate reversely by the sleeve member 32 to roll the extension body 73 of the banding unit 70.

It should be noted that when the driving device 10 stops driving the rotating shaft 31 to stop the rotating shaft 31, 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, and 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 received in the self-locking groove 310 of the rotating shaft 31, so that the sleeve member 32 can still freely rotate positively with respect to the axis of the rotating shaft 31, and thus the rolling member 20 can also freely rotate positively with respect to the axis of the rotating shaft 31 to release the extending body 73 of the binding element 70.

Preferably, each of the locking grooves 310 has an inclined bottom surface 311, wherein the inclined bottom surface 311 of the locking groove 310 extends obliquely inward along the direction of the reverse rotation of the rotating shaft 31, so that the depth of the 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 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 10 to drive the locking member 33 to rotate reversely around the axis of the rotating shaft 31, the locking member 33 slides along the inclined bottom surface 311 under its own centrifugal force to move away from the axis of the rotating shaft 31, so that the locking member 33 is abutted between the sleeve member 32 and the inclined bottom surface 311 of the locking groove 310 to generate a frictional force, thereby causing the sleeve member 32 to rotate reversely around the axis of the rotating shaft 31 under the frictional force, so as to drive the rolling member 20 to rotate reversely.

In other words, the inclined bottom surface 311 of each of the self-locking grooves 310 extends obliquely from the self-locking position 3102 to the free position 3101 in 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 smaller than the depth of the self-locking groove 310 at the free position 3101, so that each of the locking pieces 33 moves from the free position 3101 of the corresponding self-locking groove 310 to the self-locking position 3102 to abut between the inclined bottom surface 311 of the self-locking groove 310 and the sleeve member 32 by the centrifugal force.

Illustratively, in an example of the present application, as shown in fig. 7A and 7B, the inclined bottom surface 311 of each of the latching grooves 310 may be implemented as an inclined plane 3111 to ensure that the inclined bottom surface 311 of each of the latching grooves 310 continuously extends obliquely from the latching position 3102 to the free position 3101 in a direction of reverse rotation of the rotation shaft 31.

Of course, in another example of the present application, as shown in fig. 8A and 8B, the inclined bottom surface 311 of each self-locking groove 310 may also be implemented as a concave curved surface 3112 to reduce the depth variation of the self-locking groove 310 near the free position 3101, which helps to guide the locking element 33 to move from the free position 3101 to the self-locking position 3102 under the action of centrifugal force. It is understood that the concave surface 3112 may be implemented as a circular arc surface or a non-circular arc surface, which is not described herein again.

It is worth mentioning that, according to the above embodiment of the present application, as shown in fig. 6 to 7B, the locking piece 33 of the one-way lock assembly 30 of the dial device 1 may have, but is not limited to, a cylindrical structure in which the diameter of the locking piece 33 is smaller than the depth of the self-locking groove 310 at the free position 3101 and is larger than the depth of the self-locking groove 310 at 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 abutted between 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 reversely through the rotating shaft 31 and the locking member 33, and further drive the rolling member 20 to rotate reversely around the axis of the rotating shaft 31; on the other hand, it can be ensured that when the locking element 33 is in the free position 3101 of the self-locking groove 310, the locking element 33 does not clampingly abut between the sleeve member 32 and the inclined bottom surface 311, so that the sleeve member 32 can freely rotate relative to the axis of the rotating shaft 31, and thus the rolling member 20 can freely rotate around the axis of the rotating shaft 31 in the forward direction.

Preferably, the plurality of self-locking grooves 310 in the one-way lock assembly 30 are axisymmetrically arranged on the outer circumference of the rotating shaft 31.

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 sleeved on the rotating shaft 31, and simultaneously avoid the problem of shaking or swinging between the sleeve member 32 and the rotating shaft 31 due to a large gap.

It should be noted that, since friction is inevitably generated between the rotating shaft 31, the sleeve member 32 and the locking member 33 due to mutual movement, especially when the rotating disc apparatus 1 is in the self-locking state, the locking member 33 completely depends on the friction to drive the sleeve member 32 to rotate in the opposite direction, the rotating shaft 31, the sleeve member 32 and the locking member 33 of the present application can be made of, but not limited to, materials with certain hardness and rigidity, such as steel or alloy, which helps to prolong the service life of the rotating disc apparatus 1.

According to the above-mentioned embodiments of the present application, the driving device 10 may be, but is not limited to, implemented as a device, such as a motor or a motor, capable of driving the rotating shaft 31 to rotate reversely. In addition, the rotating shaft 31 may be directly or indirectly mounted to the output shaft of the driving device 10, which is not described in detail herein.

In the above-mentioned embodiment of the present application, as shown in fig. 4A and 5, the rolling member 20 of the rotary plate device 1 may be, but is not limited to be, implemented as a rolling plate 21 for rollably receiving the strapping element 70, wherein the rolling plate 21 is relatively fixedly mounted to the sleeve member 32 of the one-way lock assembly 30, so that the rolling plate 21 can be synchronously rotated with the sleeve member 32.

Preferably, the reel 21 is removably 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 bundling element 70 on the reel 21 is released, the empty reel 21 is detached from the sleeve member 32, and the reel 21 wound with the bundling element 70 is attached to the sleeve member 32, so that the fuel cell stack 800 can be continuously bundled by the turntable device 1.

Illustratively, as shown in fig. 7A and 7B, 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 matched with 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, and 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 groove 321 and the limiting block 211 may also be exchanged, or the reel 21 and the sleeve member 32 may be detachably fixed together by a method such as a screw, and the details of the present application are omitted.

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 may be, but is not limited to, made of a material such as plastic, which contributes to reducing the overall weight of the carousel device 1 and thus 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 may be integrally connected, that is, the reel 21 and the sleeve member 32 may be integrally machined by a material such as steel or alloy.

Further, in the above-described embodiment of the present application, the inclined bottom surface 311 of each of the self-locking grooves 310 extends obliquely inward from the outer circumferential wall of the rotation shaft 31 in the direction of reverse rotation of the rotation shaft 31 to form the self-locking groove 310 having a wedge structure, so that the depth of the starting point of the self-locking groove 310 cannot be utilized because it is much smaller than the diameter of the locking piece 33. In order to ensure that the depth of the end point of the self-locking groove 310 is greater than the diameter of the locking element 33 and to avoid the depth of the self-locking groove 310 from changing too much, the inclined bottom surface 311 of the self-locking groove 310 has to be set long enough, so that it is difficult to set more self-locking grooves 310 on the rotating shaft 31, and the number of the self-locking grooves 310 is small, which easily affects the working stability of the one-way lock assembly 30 and thus the working stability of the rotary plate device 1.

In order to solve the above problem, fig. 9A and 9B show a first modified embodiment of the turntable device 1 according to the above embodiment of the present application. The carousel device 1 according to this variant embodiment of the present application differs from the above-described embodiment of the present application in that: the latching groove 310 of the rotation shaft 31 of the one-way lock assembly 30 has a front side 312 and a rear side 313, and the inclined bottom 311 of the latching groove 310 extends from the front side 312 to the rear side 313 obliquely inward along the direction of reverse rotation of the rotation shaft 31 to form the latching groove 310 having a trapezoid-like structure such that the starting point depth of the latching groove 310 is close to the diameter of the locking piece 33 to fully utilize the inclined bottom 311 of the latching groove 310, which helps to shorten the length of the inclined bottom 311 of the latching groove 310, so that as many latching grooves 310 as possible are provided on the rotation shaft 31, thereby improving the operational stability of the rotary disc apparatus 1. It is understood that the reverse rotation direction of the rotation shaft 31 of the present application refers to a direction from the front side 312 of the self-locking groove 310 to the rear side 313 of the self-locking groove 310.

Preferably, the front side 312 and the rear side 313 of the self-locking groove 310 each extend in a radial direction of the rotation shaft 31, and a radial length of the front side 312 of the self-locking groove 310 is smaller than a diameter of the locking piece 33, and a radial length of the rear side 313 of the self-locking groove 310 is larger than a diameter of the locking piece 33, such that a length of the front side 312 of the self-locking groove 310 is equal to a starting point depth of the self-locking groove 310, and a length of the rear side 313 of the self-locking groove 310 is equal to a finishing point depth of the self-locking groove 310. In other words, the free position 3101 of the self-locking slot 310 of the present application is located adjacent to the back side 313 of the self-locking slot 310, and the self-locking position 3102 of the self-locking slot 310 is located adjacent to the front side 312 of the self-locking slot 310, such that when the locking element 33 is in the free position 3101 of the self-locking slot 310, the locking member 33 is completely received in the self-locking groove 310, to prevent the locking member 33 from contacting the sleeve member 32 to generate unnecessary friction, and when the locking member 33 is moved to the self-locking position 3102 of the self-locking groove 310 by the centrifugal force, the locking element 33 is partially exposed outside the self-locking groove 310 to generate a frictional force against the sleeve member 32, so that the sleeve member 32 rotates reversely around the axis of the rotating shaft 31 under the action of friction force, and the rolling member 20 is driven to rotate reversely around the axis of the rotating shaft 31.

It should be noted that when the driving device 10 drives the rotating shaft 31 to rotate reversely so that the locking member 33 is located at the self-locking position 3102 of the self-locking groove 310, the locking member 33 is abutted between the sleeve member 32 and the rotating shaft 31, and at this time, if the driving device 10 stops driving the rotating shaft 31 to rotate reversely and pulls the bundling member 70 so that the rolling member 20 drives the sleeve member 32 to rotate normally, the locking member 33 will easily stay at the self-locking position 3102 of the self-locking groove 310 under the friction force provided by the sleeve member 32 to prevent the rolling member 20 from rotating normally, thereby affecting the normal operation of the turntable device 1.

Therefore, in order to solve this problem, fig. 10 to 11B show a second modified embodiment of the turntable device 1 according to the above-described embodiment of the present application. Compared to the above-described first variant embodiment according to the present application, the carousel device 1 according to this variant embodiment of the present application differs in that: the unidirectional lock assembly 30 further comprises one or more reset elements 34, wherein each reset element 34 is disposed between the latching groove 310 and the locking element 33, respectively, for providing a reset force to the locking element 33, so that the locking element 33 moves from the latching position 3102 of the latching groove 310 to the free position 3101 when the driving device 10 stops driving the rotating shaft 31 to rotate reversely, so as to prevent the locking element 33 from staying at the latching position 3102 of the latching groove 310 when the driving device 10 stops driving, thereby ensuring the normal operation of the rotary plate device 1. It is understood that the reset force provided by the reset element 34 to the lock 33 in this application does not prevent the lock 33 from moving under centrifugal force to the self-locking position 3102, i.e., the lock 33 can move under centrifugal force from the free position 3101 to the self-locking position 3102.

More specifically, in an example of the present application, as shown in fig. 11A and 11B, the reset element 34 of the one-way lock assembly 30 may be implemented as an elastic element 341, wherein the elastic element 341 is correspondingly disposed between the front side 312 of the self-locking groove 310 and the lock 33, and when the lock 33 is at the self-locking position 3102 of the self-locking groove 310, the elastic element 341 is elastically deformed (e.g., compressed) to apply an elastic force to the lock 33, so that the lock 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 reversely rotate. For example, in this example of the present application, the elastic element 341 may be, but is not limited to being, implemented as a compression spring.

Of course, in another example of the present application, the elastic member 341 may be disposed between the rear side surface 313 of the self-locking groove 310 and the locking member 33, and when the locking member 33 is at the self-locking position 3102 of the self-locking groove 310, the elastic member 341 is elastically deformed (e.g., stretched) to apply an elastic force to the locking member 33, so that the locking member 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 reversely. For example, in this example of the present application, the elastic element 341 may be, but is not limited to being, implemented as a tension spring.

In addition, in other examples of the present application, the reset element 34 of the one-way lock assembly 30 may also be implemented as a magnetic element (not shown in the drawings), so that the magnetic force (including a magnetic attraction force or a magnetic repulsion force) applied to the lock 33 by the magnetic element is used as the reset force, and the lock 33 can still move 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 reversely.

s113: and when the rotating shaft is driven by the driving device to rotate reversely, each locking piece 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 against between the rotating shaft and the sleeve piece, so that the sleeve piece can rotate reversely along with the rotating shaft.
