Description

Technical Field

[0001] The utility model relates to the technical field of plate cleaning tools, in particular to a cleaning device. Background Art

[0002] Flexible graphite bipolar plates are a key component of fuel cell stacks. The primary process involves molding the expanded graphite raw plate. This stage primarily utilizes an integrated mold, which simultaneously completes the partial molding of the plate product and removes excess material. This can result in burrs remaining on the edges of the cuts. To prevent these burrs from dislodging and entering the flow channels during stack operation, potentially blocking them and affecting stack performance, the edges of the graphite plates must be deburred after impregnation to ensure their safety during use. Currently, manual cleaning of multiple plates is the standard practice.

[0003] However, since multiple plates are stacked together, when cleaning the inlet and outlet of the plates, the burrs are easily moved up and down with the cleaning tools, and then hidden in the gap between two adjacent plates. Manual rotation tools are required for cleaning, but it is difficult to clean them thoroughly, and the labor intensity is high and the cleaning efficiency is low. In addition, since flexible graphite plates are brittle and soft, they are easily worn when cleaned with general tools. Improper cleaning may also cause plate defects, leading to scrapping.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to solve the problem of low cleaning efficiency of the cleaning tools in the prior art for the inlet and outlet of the electrode plate, the utility model provides a cleaning device.

[0027] Please refer to Figures 1 to 6 As shown, applying the technical solution of the present invention, the cleaning device includes a placing tool 10 and a cleaning structure 20; the placing tool 10 has a accommodating space 11 for accommodating multiple electrode plates 1 stacked in sequence, and the placing tool 10 is provided with a cleaning port 12 connected to the accommodating space 11, and the inlet and outlet channels 2 on the multiple electrode plates 1 are connected to the cleaning port 12; the cleaning structure 20 includes a brush head component 21 that can be spirally moved in the vertical direction, the brush head component 21 includes a connecting member 210 and multiple brush bristles 211 that are spaced apart along the extension direction of the connecting member 210, and at least a portion of each brush bristle component 211 is arranged at a preset angle to the extension direction of the connecting member 210, so that the brush head component 21 extends into the inlet and outlet channel 2 and cleans the gap between two adjacent electrode plates 1 among the multiple electrode plates 1 located in the inlet and outlet channel 2.

[0028] Using the technical solution of this embodiment, multiple electrode plates 1 are stacked in sequence and placed at a designated position on a placement fixture 10, with the inlet and outlet channels 2 on the electrode plates 1 corresponding to the cleaning openings 12 on the placement fixture 10. The position of the cleaning structure 20 is adjusted to align with the edges of the electrode plates 1 on the placement fixture 10. In this way, the brush head component 21 of the cleaning structure 20 is controlled to extend into the cleaning opening 12 in a vertical spiral motion to clean the inlet and outlet channels 2 of the multiple electrode plates 1. Since each bristle member 211 is arranged at a certain angle to the connecting member 210, when the brush head component 21 spirals in the vertical direction, it drives the inclined bristle members 211 to penetrate between two adjacent electrode plates 1 during the up-down and rotation process, so that burrs located between the two adjacent electrode plates 1 are separated from the electrode plates 1 by the rotation of the bristle members 211, thereby achieving the purpose of removing hidden burrs, improving the performance and life of the fuel cell, and thus solving the problem of low cleaning efficiency of the electrode plate 1 inlet and outlet cleaning tools in the prior art.

[0029] In this embodiment, the inlet and outlet channels 2 of the electrode plates 1 are channels for fuel and coolant to enter and exit during the operation of the fuel cell stack.

[0030] like Figure 6 As shown, the bristle member 211 includes a connector 2110, first bristles 2111, and second bristles 2112. The connector 2110 is disposed on the connector 210. The first bristles 2111 and the second bristles 2112 are symmetrically disposed on opposite sides of the connector 2110. The first bristles 2111 and the second bristles 2112 are respectively disposed at a preset angle with the connector 210. The preset angle A satisfies the following conditions: 75°≤A≤85°. In the above configuration, the connector 2110 is circular, disposed around the axis of the connector 210 and perpendicular to the extension direction of the connector 210. The first bristles 2111 and the second bristles 2112 are respectively arranged in a conical structure around the axis of the connector 210 and symmetrically disposed on both sides of the connector 2110. In this way, during the up and down movement and rotation process, the first bristles 2111 and the second bristles 2112 can extend into the gap between two adjacent pole plates 1 at multiple angles to remove the burrs hidden therein.

[0031] Optionally, the connector 2110 , the first bristles 2111 and the second bristles 2112 are all long strip structures and are an integrally formed structure, and a plurality of bristle pieces 211 are sequentially arranged around the axis direction of the connector 210 .

[0032] In order to prevent the bristles from damaging the electrode plate 1 while effectively cleaning the bristles, in this embodiment, the hardness and length of the first bristles 2111 and the second bristles 2112 are controlled within a certain range.

[0033] like Figure 4 and Figure 5 As shown, the cleaning structure 20 includes a support frame 22 and a connecting member 23; one end of the connecting member 23 is connected to the support frame 22, and the other end of the connecting member 23 is connected to the brush head member 21. At least a portion of the connecting member 23 is arranged to be movable in the horizontal direction to drive the brush head member 21 to move horizontally. In this way, driven by the connecting member 23, the brush head member 21 can move horizontally to a corresponding position, so that the brush head member 21 can be inserted into the cleaning port 12 for cleaning.

[0034] Specifically, the connecting component 23 includes a first connecting rod 230 and a second connecting rod 231 that are relatively rotatably connected in the horizontal direction. The end of the first connecting rod 230 away from the second connecting rod 231 is adjustably connected to the support frame 22 along the extension direction of the support frame 22, and the end of the second connecting rod 231 away from the first connecting rod 230 is connected to the brush head component 21. In the above arrangement, the first connecting rod 230 and the second connecting rod 231 are fixedly connected together by bolts, and one end of the first connecting rod 230 is fixedly connected to the support frame 22. The bolts can be adjusted according to cleaning needs to rotate the second connecting rod 231 in the horizontal direction relative to the first connecting rod 230, thereby driving the brush head component 21 to be adjusted to any position in the horizontal direction.

[0035] like Figure 4 and Figure 5 As shown, the cleaning structure 20 includes a movable component 24, which is connected to the connecting component 23. The movable component 24 includes an outer shell 240 and a rotating member 241 that is arranged in the outer shell 240 and can be spirally moved in the vertical direction. The brush head component 21 is connected to the rotating member 241 so that the rotating member 241 drives the brush head component 21 to move spirally in the vertical direction. In this way, by adjusting the connecting component 23 to drive the brush head component 21 to move horizontally to the top of the cleaning port 12, and then by controlling the rotating member 241 to spirally rotate in the vertical direction in the outer shell 240, the brush head component 21 is driven to extend into the cleaning port 12 and clean the gaps between the multiple plates 1.

[0036] Specifically, the rotating member 241 is a worm, the connecting member 23 is provided with a driving member 25, the output shaft of the driving member 25 is connected to a turbine 250, the outer shell 240 is provided with a mounting opening, the turbine 250 extends into the mounting opening and is meshed with the worm, so that the driving member 25 drives the brush head member to move spirally in the vertical direction. In the above arrangement, the driving member 25 is a micro motor, and the micro motor has two gears: forward gear and reverse gear. In this way, under the drive of the driving member 25, the turbine 250 and the worm are meshed and rotated, thereby realizing the up and down reciprocating motion of the brush head member 21, so as to clean the burrs on the upper and lower surfaces of the electrode plate 1 and the burrs in the gap between two adjacent electrode plates 1.

[0037] In this embodiment, there is a certain distance between the end of the rotating shaft of the rotating member 241 and the thread thereon.

[0038] In this embodiment, the first connecting rod 230 is connected to the support frame 22 via a clamp 26. The clamp 26 is secured to the support frame 22 via a fastening bolt. The shape and size of the clamp 26 match the support frame 22, allowing for free adjustment of the height of the brush head 21. This provides convenient and flexible operation, ensures the stability of the brush head 21 during operation, and enhances cleaning effectiveness. Furthermore, in actual use, the brush head 21 can be replaced by removing the clamp 26 as needed, facilitating maintenance and replacement.

[0039] Optionally, a slider is connected to one end of the first connecting rod 230, and a slide groove is provided along the extension direction of the support member, and the slider extends into the slide groove and is slidably connected. In this way, by controlling the slider at one end of the first connecting rod 230 to slide in the slide groove on the support frame 22, the brush head component 21 can be moved vertically to different height positions.

[0040] In this embodiment, the lengths of the first and second bristles 2111, 2112 are both predetermined, with the predetermined length L satisfying the following relationship: 5 mm ≤ L ≤ 8 mm. This ensures that when removing graphite burrs from the gap between two adjacent electrode plates 1, both the first and second bristles 2111, 2112 can reach the gap between the two electrode plates 1, effectively reaching and removing any remaining flaky burrs.

[0041] In this embodiment, both the first and second bristles 2111, 2112 are made of nylon. As the first and second bristles 2111, 2112 are inserted into the gap between two adjacent plates 1 to remove burrs, the nylon material's flexibility allows it to adapt to the surface characteristics of the flexible graphite bipolar plates 1 and prevent wear or damage to the plates 1 during the cleaning process, thereby ensuring the integrity and performance of the plates 1. Furthermore, nylon has excellent wear resistance and toughness, capable of withstanding the friction and pressure during the cleaning process. Compared to other hard materials, it wears more slowly, extending the life of the cleaning tool and reducing the cost of frequent tool replacement.

[0042] like Figures 1 to 3As shown, the placement tool 10 includes a first mounting plate 13 and a second mounting plate 14 connected in parallel to each other. Cleaning ports 12 are provided at both ends of the first mounting plate 13 and the second mounting plate 14, respectively. The cleaning ports 12 on the first mounting plate 13 and the second mounting plate 14 are respectively connected to the inlet and outlet channels 2 on the plurality of electrode plates 1; wherein the cross-sectional area of ​​the cleaning port 12 is smaller than the cross-sectional area of ​​the inlet and outlet channels 2. With the above arrangement, the shape of the cleaning port 12 is the same as that of the inlet and outlet channels 2, and the size of the cleaning port 12 is slightly smaller than that of the inlet and outlet channels 2, so that the brush head component 21 can pass through all the electrode plates 1. In addition, it can ensure that the brush head component 21 is in closer contact with the edge of the electrode plate 1 when passing through the cleaning port 12, which helps the first bristles 2111 and the second bristles 2112 of the brush head component 21 to better enter the gap between two adjacent electrode plates 1 and thoroughly remove the remaining burrs, thereby improving the cleaning efficiency and effect of the brush member 211.

[0043] Specifically, the placement tool 10 further includes a first baffle 15 and a second baffle 16. The first mounting plate 13 and the second mounting plate 14 respectively have adjacent first and second side edges. The first baffle 15 is respectively connected to the two first side edges, and the second baffle 16 is respectively connected to the two second side edges to enclose the accommodating space 11. In this way, multiple electrode plates 1 are placed in the accommodating space 11, and the first baffle 15 and the second baffle 16 respectively block the multiple electrode plates 1 to ensure that the inlet and outlet channels 2 on the multiple electrode plates 1 are accurately aligned with the cleaning ports 12 on the first mounting plate 13 and the second mounting plate 14, respectively. Moreover, when the brush head component 21 rotates at high speed and moves up and down, the electrode plates 1 can be kept stable to prevent displacement or vibration of the electrode plates 1 during the cleaning process, thereby avoiding the problem of incomplete cleaning or damage to the electrode plates 1 due to position offset during the cleaning process.

[0044] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0045] The cleaning device includes a placement tool 10 and a cleaning structure 20; the placement tool 10 has a accommodating space 11 for accommodating multiple electrode plates 1 stacked in sequence, and the placement tool 10 is provided with a cleaning port 12 connected to the accommodating space 11, and the inlet and outlet channels 2 on the multiple electrode plates 1 are connected to the cleaning port 12; the cleaning structure 20 includes a brush head component 21 that can be spirally moved in the vertical direction, the brush head component 21 includes a connecting member 210 and multiple brush bristles 211 that are spaced apart along the extension direction of the connecting member 210, and at least part of each brush bristle component 211 is arranged at a preset angle to the extension direction of the connecting member 210, so that the brush head component 21 extends into the inlet and outlet channel 2 and cleans the gap between two adjacent electrode plates 1 among the multiple electrode plates 1 located in the inlet and outlet channel 2. In the above arrangement, multiple electrode plates 1 are stacked in sequence and placed on the placement fixture 10 at a specified position, and the inlet and outlet channels 2 on the electrode plates 1 correspond to the cleaning openings 12 on the placement fixture 10. The position of the cleaning structure 20 is adjusted to align with the edges of the electrode plates 1 on the placement fixture 10. In this way, the brush head component 21 of the cleaning structure 20 is controlled to extend into the cleaning opening 12 in a vertical spiral motion to clean the inlet and outlet channels 2 of the multiple electrode plates 1. Since each brush member 211 is arranged at a certain angle to the connecting member 210, when the brush head component 21 spirals in the vertical direction, it drives the inclined brush members 211 to penetrate between two adjacent electrode plates 1 during the up and down movement and rotation process, so that the burrs between the two adjacent electrode plates 1 are separated from the electrode plates 1 by the rotation of the brush members 211, thereby achieving the purpose of removing hidden burrs, thereby solving the problem of low cleaning efficiency of the cleaning tools in the prior art for the inlet and outlet of the electrode plates 1.
