Description

Technical Field

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

[0002] The bipolar plate, as the backbone of a fuel cell, is one of its main components, performing functions such as current conduction, fuel gas distribution, reaction heat dissipation, and ensuring the mechanical strength of the fuel cell. Most bipolar plates in fuel cells are rectangular thin sheets with complex surface structures. The front and back sides have dense gas distribution channels, and the interior has dense cooling water channels. They are also thin and soft, making them prone to deformation and dirt. Furthermore, the sizes of the plates vary depending on the operating power design and application scenarios of the stack. This combination of functional and dimensional requirements places significant restrictions on cleaning the plates.

[0003] Currently, there are no specialized cleaning tools (such as cleaning baskets) specifically tailored for bipolar plates. Conventional cleaning tools designed for plate- or sheet-like products can harbor dirt and cause damage when used on bipolar plates. They also struggle to meet the quality requirements for bipolar plate cleaning, often due to industry-specific limitations. Therefore, there is a need for cleaning tools that are suitable for plates of various sizes, effectively clean them, and prevent deformation and damage during cleaning.

[0004] Therefore, it is necessary to provide a new type of cleaning tool to solve the above problems existing in the prior art. Utility Model Content

[0023] (3) By setting multiple installation positions on the frame, the corresponding installation position can be selected to install the limit component according to the height specifications of the cleaning object, so that the same cleaning tool can be used for cleaning objects of various specifications; by designing the matching structure of the slide rod and the guide column, and setting the hanger on the slide rod, the distance between the hook and the bottom plate of the limit component can be flexibly adjusted, ensuring that the bottom of the cleaning object can be suspended through the aisle and located above the bottom plate, realizing multi-size fine adjustment of the cleaning tool for cleaning objects of different heights in the vertical direction, fully meeting the cleaning needs of the diverse sizes of plate-shaped cleaning objects, and improving the applicability and universality of the cleaning tool in multiple industries.

[0024] (4) By designing a hanger structure in which the loading part and the introduction part are movable and coordinated, the loading part can be pulled out from the introduction part to hang the cleaning object, and after hanging the cleaning object, the loading part can be returned to the introduction part, so that the cleaning object can be loaded into the frame along a predetermined path, which not only facilitates operation but also reduces the interaction between cleaning objects.

[0025] (5) By arranging multiple hangers in parallel and multiple limiting parts in conjunction with them, the production capacity and cleaning efficiency can be greatly improved, thereby reducing production costs.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0037] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0038] refer to Figure 1-Figure 3 The utility model provides a cleaning tool, which comprises a frame 1, a hanger 2 and a limiting component 3.

[0039] The frame 1 encloses a storage space 4. The front face of the frame 1 (the working face facing the drawing in the figure) has a loading window 41 that connects to the storage space 4. In other words, the frame 1 is a continuous frame-shaped structure, which encloses the storage space 4 within the frame structure. Furthermore, the storage space 4 is exposed on the front face of the frame 1, thereby forming the loading window 41 on the front face of the frame 1. After the cleaning object 5 is loaded and clamped into the storage space 4 through the loading window 41, the cleaning tool is placed in a cleaning station (e.g., a cleaning tank) to clean the cleaning object 5 clamped in the frame 1 of the cleaning tool.

[0040] Generally, the accommodating space 4 is also exposed on the back side of the frame 1, forming a circulation window for the cleaning liquid on the back side of the frame 1. It will be understood that the circulation window on the back side of the frame 1 is not used to load the cleaning object 5.

[0041] The hanger 2 is arranged on the frame 1 and is located in the accommodating space 4. For example, the hanger 2 can be arranged in the accommodating space 4 at a position close to the top of the frame 1 to effectively utilize the accommodating space 4.

[0042] The hanger 2 includes an inlet portion 21, a loading portion 22, and a hooking portion 23. The inlet portion 21 is mounted on the frame 1, the loading portion 22 is movably coupled to the inlet portion 21, and the hooking portion 23 is mounted on the loading portion 22. The loading portion 22 is configured to move on the inlet portion 21 to laterally load the plate-shaped cleaning object 5 hung on the hooking portion 23 into the receiving space 4 through the loading window 41. Lateral loading means loading the plate-shaped cleaning object 5 into the receiving space 4 with one side facing the loading window 41.

[0043] The limit assembly 3 is mounted on the frame 1 and located in the receiving space 4 below the hanger 2. The limit assembly 3 includes limiters 31, which are located on either side of the loading path for the cleaning object 5. These limiters 31 are used to limit the bottom swing of the cleaning object 5 after loading, thereby preventing the cleaning object 5 from swinging violently toward the left or right side of the frame 1 during the cleaning process.

[0044] The cleaning object 5 can be a plate-shaped product with a mounting hole (opening). For example, the cleaning object 5 can be a bipolar plate 51 of a fuel cell. The top surface of the bipolar plate 51 typically has a structural opening (first structural opening 511) that allows the bipolar plate 51 to be mounted. The following describes an example of a cleaning tool according to the present invention being used to mount a bipolar plate 51 for cleaning.

[0045] Further references Figure 4. In some embodiments, the introduction portion 21 is a horizontally arranged strip, and one end of the strip of the introduction portion 21 faces the loading window 41. A horizontal introduction groove 211 is provided in the introduction portion 21 along the length direction of the strip, and a card slot 212 connected to the introduction groove 211 is also provided in the same direction on the bottom of the introduction portion 21. The width of the card slot 212 is smaller than the width of the introduction groove 211; and the introduction groove 211 and the card slot 212 have an introduction port on the first end of the introduction portion 21 facing the loading window 41. The loading portion 22 is a horizontally arranged strip, and a slider 221 is provided on the top of the loading portion 22 along the length direction of the strip. The slider 221 is used to be installed in the introduction groove 211 to form a sliding fit. The lateral dimension of the slider 221 is larger than the dimension of the card slot 212, and the lateral thickness of the bottom of the loading portion 22 below the slider 221 is smaller than the dimension of the card slot 212. When the loading part 22 is installed and matched with the introduction part 21, one end of the loading part 22 is inserted into the introduction groove 211 through the slider 221, so that one end of the loading part 22 enters the introduction groove 211 and the card slot 212 from the introduction port, and moves and cooperates with the introduction groove 211 and the card slot 212; at the same time, the bottom of the loading part 22 is exposed from the card slot 212 downward to the introduction part 21.

[0046] The hooking portion 23 includes two hooks, which are movably arranged on the exposed bottom of the loading portion 22 in sequence along the direction toward the loading window 41. That is, the two hooks are movably arranged on the exposed bottom of the loading portion 22 in sequence along the strip length direction of the loading portion 22.

[0047] In some embodiments, two horizontal through sliding grooves 222 are sequentially provided on the exposed bottom side surface of the loading portion 22 toward the loading window 41, that is, along the strip length direction of the loading portion 22, and each sliding groove 222 is used to movably load a hook.

[0048] The end of the loading portion 22 facing the loading window 41 may further be provided with a handle mounting hole 223 for mounting a handle (see FIG. Figure 7 The handle 2231 in the middle is provided to facilitate the extraction of the loading portion 22 or the return of the loading portion 22 to the introduction portion 21.

[0049] The present invention designs a hanger 2 structure in which the loading portion 22 and the introduction portion 21 are movably matched. The loading portion 22 can be pulled out from the introduction portion 21 to hang the bipolar plate 51. After the bipolar plate 51 is hung, the loading portion 22 is returned to the introduction portion 21, so that the bipolar plate 51 can be loaded into the frame 1 along a predetermined path. This not only facilitates operation but also reduces the interference between the bipolar plates 51 when hanging multiple bipolar plates 51.

[0050] Further references Figure 5In some embodiments, the hook includes a mounting portion 231 at an upper end and a hook portion 232 at a lower end. The mounting portion 231 is provided with a sliding shaft 2312. A first stopper 2311 is provided at the front end of the sliding shaft 2312. A second stopper 2315 is provided at the rear end of the sliding shaft 2312 near the hook portion 232. The hook portion 232 is connected to the second stopper 2315. A pressing block 2313 is sleeved on the sliding shaft 2312 between the first stopper 2311 and the second stopper 2315, and is slidably engaged with the sliding shaft 2312. A spring 2314 is sleeved on the sliding shaft 2312 between the pressing block 2313 and the second stopper 2315. The sliding shaft 2312 is configured to be inserted into the sliding groove 222. The first stopper 2311 and the pressing block 2313 are configured to be moved from opposite sides of the mounting portion 22. Under the elastic force of the spring 2314, the sliding shaft 2312 is elastically restrained in the sliding groove 222.

[0051] In some embodiments, the first stopper 2311, the second stopper 2315, and the pressing block 2313 are preferably circular. The rear end of the hook 232 is embedded or welded to the second stopper 2315. The front end of the hook 232 has a bend to prevent damage to the bipolar plate 51 during installation.

[0052] refer to Figure 4 and Figure 5 Combined with reference Figure 1 and Figure 3 . In some embodiments, the length of the sliding groove 222 in the horizontal direction is greater than the height in the vertical direction. The two sliding grooves 222 are independently arranged on the loading portion 22; and, a through hole 2221 is respectively provided on the opposite ends of the two sliding grooves 222. Among them, the aperture of the through hole 2221 is greater than the height of the sliding groove 222, and the diameters of the circular first stopper 2311, the second stopper 2315 and the pressing block 2313 on the hook are greater than the diameter of the sliding shaft 2312, and are coaxially arranged with the sliding shaft 2312. The diameter of the first stopper 2311 is smaller than the aperture of the through hole 2221, the diameter of the pressing block 2313 is larger than the aperture of the through hole 2221, and the diameter of the sliding shaft 2312 is smaller than the height of the sliding groove 222. The through hole 2221 is used for the passage of the first stopper 2311 on the sliding shaft 2312. Among them, after the sliding shaft 2312 passes through the through hole 2221 with the first stop block 2311 as the starting end, the sliding shaft 2312 is moved laterally out of the through hole 2221 toward the opposite end in the sliding groove 222, so that the first stop block 2311 and the clamping block 2313 elastically restrict the sliding shaft 2312 in the sliding groove 222 from both sides of the loading portion 22, so that when the hook portions 232 on the two hooks are hooked on the upper edge of the first structural opening 511 on the top surface of the bipolar plate 51 for hanging, the hook can realize self-positioning of the hook through its own adaptive sliding and rotation.

[0053] In some embodiments, the length of the sliding shaft 2312 is greater than the thickness of the sliding groove 222, that is, greater than the thickness of the loading portion 22, so that when the bipolar plate 51 is mounted on the hook, under the action of the gravity of the mounted bipolar plate 51 and the elastic force of the spring 2314, the sliding shaft 2312 can produce adaptive sliding and rotation in the sliding groove 222, thereby realizing adaptive fine-tuning of the hook when the bipolar plate 51 is mounted, facilitating the search for the optimal clamping position and clamping method, and allowing the hook to be elastically pressed in the sliding groove 222 by the first stop block 2311 and the clamping block 2313 to finally obtain positioning.

[0054] By designing a resilient fit between the hook and the sliding groove 222, the present invention allows the hook to adaptively slide and rotate within the sliding groove 222 according to the force applied to the hook when attaching the bipolar plate 51. This facilitates the hook's ability to automatically find the optimal clamping position and angle, thereby achieving self-positioning of the hook. Furthermore, using the hook to attach the bipolar plate 51 minimizes contact with the bipolar plate 51, thereby avoiding the drawbacks of dirt trapping and large-area contact between materials, reducing the incidence of damage, and achieving more effective cleaning.

[0055] refer to Figures 1-4 In some embodiments, a horizontal slide bar 25 is provided in the storage space 4, and vertical guide posts 111 are provided on the two side surfaces of the frame 1 on both sides of the window 41. Slide sleeves 251 are provided on both ends of the slide bar 25; the two ends of the slide bar 25 are movably mounted on the guide posts 111 on the corresponding sides through the slide sleeves 251. The hanger 2 is connected to the bottom of the slide bar 25 through the guide portion 21, so that the hanger 2 is suspended on the frame 1 and located in the storage space 4. By moving the slide bar 25 up and down along the guide posts 111, the relative height of the hanger 2 in the storage space 4 can be adjusted.

[0056] Furthermore, a threaded pin hole 2511 is provided on the side of the sliding sleeve 251. A threaded pin (or bolt) can be positioned in the threaded pin hole 2511. By tightening the threaded pin, the sliding rod 25 is secured to the guide post 111 at a predetermined height, thereby securing the hanger 2. Alternatively, a temporary clamp can be used to secure the sliding rod 25 to the guide post 111.

[0057] In some embodiments, the position-limiting assembly 3 further includes a horizontal base plate 32, with the position-limiting portion 31 disposed on the top surface of the base plate 32. Multiple pairs of mounting positions 12 are vertically disposed on the two side surfaces of the frame 1 on either side of the insertion window 41. The position-limiting assembly 3 is selectively mounted on one of the pairs of mounting positions 12 via the ends of the base plate 32. In other words, the height of the mounting positions 12 on the frame 1, as well as the number of positions 12, correspond to the dimensions of the bipolar plates 51. When a bipolar plate 51 of a certain size needs to be cleaned, the position-limiting assembly 3 is installed on the appropriate mounting position 12, and the height of the hanger 2 can be adjusted to achieve optimal control over the clamping dimensions.

[0058] By providing multiple mounting positions 12 on the frame 1, the present invention can select the corresponding mounting position 12 to install the limit assembly 3 according to the height specifications of the bipolar plate 51, so that the same cleaning tool can be used to clean bipolar plates 51 of various specifications. In addition, by designing the matching structure of the slide bar 25 and the guide column 111 and setting the hanger 2 on the slide bar 25, the distance between the hook and the bottom plate 32 of the limit assembly 3 can be flexibly adjusted, ensuring that the bottom of the bipolar plate 51 can be suspended through the aisle between two adjacent limit portions 31 and located above the bottom plate 32, thereby achieving multi-dimensional fine control of the cleaning tool for bipolar plates 51 of different heights in the vertical direction. Since it can fully meet the cleaning needs of the diverse sizes of the plate-shaped cleaning objects 5, the applicability and universality of the cleaning tool of the present invention in multiple industries are improved.

[0059] Figure 1 、 Figure 3 and Figure 9 The state in which the limit assembly 3 is installed on a pair of installation positions 12 (the first installation position 12 from the bottom) located at the bottom of the frame 1 is shown. Figure 10 and Figure 11 The figure shows the state where the limit assembly 3 is installed on other different installation positions 12 on the frame 1, wherein: Figure 10 The state of the limit component 3 installed on the second installation position 12 from the bottom is shown. Figure 11 The state where the limit assembly 3 is installed on the third installation position 12 from the bottom is shown.

[0060] In some embodiments, multiple hangers 2 are connected in parallel to the bottom of the slide bar 25 via their respective guide portions 21. Each hanger 2 is used to hang and load a single bipolar plate 51. Furthermore, multiple limiters 31 are arranged in parallel on the bottom plate 32. Any two adjacent limiters 31 are used to limit the bottom swing of a loaded bipolar plate 51. Figure 9The figure shows the state of multiple bipolar plates 51 being mounted on a cleaning tool using multiple hangers 2. This significantly increases the number of plates that can be clamped at a time, improving production capacity and cleaning efficiency, thereby reducing production costs. Furthermore, the design of the pull-out hangers 2, and their coordinated use with the stopper assembly 3, prevents interference between the bipolar plates 51 during clamping, effectively ensuring product cleaning safety. Figure 10 and Figure 11 The same display shows the state when multiple bipolar plates 51 are mounted. Figure 9 The only difference is the size of the bipolar plate 51 , and the limiting assembly 3 is installed on the frame 1 at the corresponding installation position 12 that is adapted to the size of the bipolar plate 51 .

[0061] Combined with reference Figure 6 . In some embodiments, the limiting portion 31 includes a diamond-shaped limiting block 311 horizontally arranged on the bottom plate 32. Among them, any two adjacent limiting blocks 311 are relatively arranged through their respective corresponding top angles, and an aisle 35 is formed between the two adjacent limiting blocks 311, through which the bottom of the bipolar plate 51 passes when the bipolar plate 51 is loaded. That is, the aisle 35 is located on the loading path of the bipolar plate 51. The minimum gap between any two adjacent limiting blocks 311 is slightly larger than the thickness of the bipolar plate 51, so as to prevent the bipolar plate 51 from producing obvious deflection and shaking. The limiting block 311 can be mounted on the top surface of the bottom plate 32 by fasteners.

[0062] In some embodiments, the distance between the two farther-distance upper and lower top corners (top corners in the front-to-back direction) of the diamond-shaped limit block 311 that is not used to form the aisle 35 is greater than the width of the bottom plate 32, so that the diamond-shaped limit block 311 is exposed on both sides of the bottom plate 32 to shorten the length of the bottom surface of the aisle 35, which is beneficial to avoid hiding dirt in the aisle 35.

[0063] Furthermore, the distance between the hook and the bottom plate 32 satisfies the requirement that when the bipolar plate 51 mounted on the hook passes through the aisle 35, there is a gap greater than zero between the bottom end of the bipolar plate 51 and the bottom plate 32. Thus, the bell mouths formed by the two adjacent diamond-shaped stoppers 311 at both ends of the aisle 35 can guide the cleaning liquid in and out of the aisle 35 during cleaning, allowing the cleaning liquid to flow through the gap between the bottom end of the bipolar plate 51 and the bottom plate 32, thereby cleaning the bottom of the bipolar plate 51 located in the aisle 35 and preventing dirt from accumulating in the aisle 35.

[0064] Furthermore, the edges of the diamond-shaped stopper 311 can be rounded to prevent damage to the bipolar plate 51 caused by contact. Furthermore, a friction-reducing protective coating can be added to the edge surface of the diamond-shaped stopper 311 to better prevent damage to the bipolar plate 51.

[0065] The present invention designs a diamond-shaped limit block 311 on the bottom plate 32 of the limit assembly 3, which can limit the swing amplitude of the bipolar plate 51 after hanging, thereby preventing violent shaking during the process. At the same time, it can also minimize the contact between the bipolar plate 51 and the bipolar plate 51, thereby effectively protecting against damage and facilitating the flow of the cleaning liquid in the aisle 35 between the limit blocks 311, thereby avoiding the problem of dirt hiding at the bottom of the bipolar plate 51.

[0066] refer to Figure 3 In some embodiments, fixing seats 33 are provided at both ends of the bottom plate 32 for mounting fixing rods 34. After the bipolar plate 51 is installed in the frame 1, the fixing rods 34 are configured to pass through the second structural opening 512 on the bottom surface of the bipolar plate 51 from above the stopper 31 and be mounted on the fixing seats 33 to limit the upward movement of the bipolar plate 51. When the stopper 311 is used in conjunction with the fixing rods 34, the bipolar plate 51 can be positioned both horizontally and vertically, preventing the bipolar plate 51 from shaking violently or falling during cleaning.

[0067] Further references Figure 8 . In some embodiments, the fixing seat 33 includes a main body 333, and the main body 333 is provided on both ends of the base plate 32. The main body 333 can be a rectangular block. A mounting groove 3311 with a bottom located in the main body 333 is provided on the top of the main body 333, and the mounting groove 3311 passes through the side surfaces of the main body 333 facing the two ends of the base plate 32. The other two side surfaces of the main body 333 facing the front and back directions of the frame 1 are provided with through holes 3312 that pass through two opposite groove walls of the mounting groove 3311, and a nut 331 aligned with the through hole 3312 is provided on the side surface of the main body 333 facing the outer side of the groove wall on the side of the insertion window 41, and a knob 332 is provided in the nut 331. In addition, through holes 341 are correspondingly provided on both ends of the fixing rod 34. After the bipolar plate 51 is installed, the fixing rod 34 is passed through the second structural opening 512 on the bottom of the bipolar plate 51, and the two ends of the fixing rod 34 are placed in the installation groove 3311, so that the through hole 341 on the fixing rod 34 is aligned with the through hole 3312 on the body 333, and the knob 332 is rotated to screw the knob 332 relative to the nut 331, so that the front end of the knob 332 passes through the through hole 3312 and the through hole 341 to fix the fixing rod 34 on the fixing seat 33. Figure 8 The state before the fixing rod 34 passes through the second structural opening 512 on the bottom of the bipolar plate 51 is shown, which can be used in conjunction with the reference Figure 3 Understand it.

[0068] refer to Figures 1-4In some embodiments, the frame 1 is a rectangular frame 1. The frame 1 includes a rectangular bottom frame 14 and a rectangular top frame 13. The four corners of the bottom frame 14 are provided with columns 11, and the top frame 13 is connected to the tops of the four columns 11 through the four corners.

[0069] There are two slide bars 25, each parallel to the other. Each slide bar 25 is secured to the left and right upright posts 11, serving as guide posts 111, by means of sleeves 251 at each end. The guide portion 21 is positioned perpendicular to the two slide bars 25, with at least one end of the guide portion 21 facing the insertion window 41 positioned within the side of the corresponding slide bar 25 facing the insertion window 41. This means that this end of the guide portion 21 should avoid protruding beyond the corresponding slide bar 25.

[0070] Furthermore, a plurality of crosspieces 121 (beams) serving as mounting locations 12 are provided between the two uprights 11 on the two sides of the frame 1, corresponding to the two sides of the insertion window 41. The crosspieces 121 are provided with mounting screw holes, and corresponding mounting holes are provided at both ends of the base plate 32 of the position-limiting assembly 3. The base plate 32 can be mounted on the desired crosspieces 121 (mounting locations 12) by inserting bolts 1211, serving as fastening bolts, from top to bottom, sequentially through the mounting holes on the base plate 32 and the mounting screw holes on the crosspieces 121.

[0071] Furthermore, a limit plate 24 is provided on the frame 1. Two limit slots 241 are provided on the bottom edge of the limit plate 24. The bottoms of the limit slots 241 are located in the limit plate 24, and the limit slots 241 extend through the surface of the limit plate 24. At the same time, two capped limit pins 252 are provided on the side of a slide bar 25 near the loading window 41. The second end of the introduction portion 21 facing away from the loading window 41 has a stopper to prevent the slider 221 from sliding out of the introduction portion 21 (or, the second end of the introduction portion 21 facing away from the loading window 41 is a closed end). The depth of the limit slot 241 is greater than the distance between the capped limit pin 252 and the bottom of the introduction slot 211. After the bipolar plate 51 is installed, the end of the slider 221 on the loading portion 22 facing the loading window 41 is located within the introduction port of the introduction portion 21. The limiting plate 24 is then mounted on the side of the slide bar 25 by engaging the limiting groove 241 on the limiting plate 24 with the pin of the capped limiting pin 252. In this position, the bottom edge of the limiting plate 24 is lower than the top of the slider 221, thereby blocking and limiting the end of the slider 221. This prevents the loading portion 22 from slipping out of the introduction portion 21 during use of the cleaning tool, causing the bipolar plates 51 to fall out and be damaged.

[0072] Combined with reference Figure 7 One clamping step of the cleaning tool of the present invention is:

[0073] Step S1: First, according to the height of the bipolar plate 51 , select an appropriate installation position 12 and install the limit assembly 3 . Figure 7 In this example, the bipolar plate 51 has the largest height dimension, so the lowest mounting position 12 is selected for installation of the limit assembly 3. Simultaneously, the clearance height between the bottom end of the mounted bipolar plate 51 and the base plate 32 of the limit assembly 3 is calculated. If necessary, this clearance is adjusted by adjusting the height of the slide bar 25 to ensure that the bottom end of the bipolar plate 51 does not contact the base plate 32 when the bipolar plate 51 is installed and does not escape from the limit portion 31. Then, grasping the handle, pull the loading portion 22 on the hanger 2 out of the introduction portion 21 to an appropriate length, so that the exposed loading portion 22 is located outside the loading window 41 and the hook is in a safe position in the sliding groove 222 away from the through-hole 2221 (this means positioning the hook as close as possible to the end of the sliding groove 222 away from the through-hole 2221). Next, vertically mount a bipolar plate 51 on the hook through the first structural opening 511 on the top. The hook will adaptively adjust to the optimal mounting position.

[0074] Step S2: Support the bipolar plate 51 and push the loading portion 22 back into the introduction portion 21 using the handle 2231. During this process, assistance is required to guide the bottom of the bipolar plate 51 into the aisle 35 between two adjacent stoppers 311 on either side of the loading path. During this process, the bipolar plate 51 remains naturally suspended on the hook until the loading portion 22 is fully pushed back into the introduction portion 21, completing the loading of one bipolar plate 51.

[0075] Next, the subsequent bipolar plates 51 can be loaded into the frame 1 one by one in the above manner. Figure 9 .

[0076] Step S3: Install the limiting plate 24 on the side of the slide bar 25 to block and limit the slider 221 of the loading portion 22 in the introduction portion 21 to prevent the loading portion 22 from slipping out of the introduction portion 21 .

[0077] If the fixing rod 34 structure is not used, the clamping of the bipolar plate 51 is completed. At this time, the cleaning tool with the bipolar plate 51 can be placed in the cleaning station for cleaning.

[0078] Furthermore, if the fixed rod 34 structure is adopted, the following steps may be further included:

[0079] Step S4: After the bipolar plates 51 are installed in the frame 1, the fixing rods 34 are passed from above the stopper 31 through the second structural opening 512 on the bottom surface of the bipolar plates 51. The fixing rods 34 are then mounted on the fixing base 33 to restrict the upward movement of the bipolar plates 51. At this point, the cleaning tool containing the bipolar plates 51 can be placed in the cleaning station for cleaning.

[0080] According to the above steps, the same cleaning tool can be used to clamp other bipolar plates 51 of different sizes. For example, by adjusting the limit assembly 3 to be located at the uppermost mounting position 12, the bipolar plate 51 with the smallest height dimension can be clamped in the frame 1, as shown in FIG. Figure 11 Alternatively, by adjusting the limit assembly 3 to be located at a middle mounting position 12, the bipolar plate 51 with a height dimension between the maximum and minimum can be clamped in the frame 1, as shown. Figure 10 shown.

[0081] In summary, the present invention provides a hanger 2 and a limit assembly 3 located below the hanger 2 in the storage space 4 within the cleaning fixture frame 1, and provides a loading portion 22 with a hanging portion 23 that can move relative to the introduction portion 21 on the hanger 2. When the plate-shaped cleaning object 5 (bipolar plate 51) hung on the hanging portion 23 is laterally moved and loaded into the storage space 4, the limit assembly 3 is provided with limit portions 31 located on both sides of the loading path to limit the bottom swing amplitude of the cleaning object 5, which can effectively prevent deformation and damage to the cleaning object 5. The open design of the limit portion 31 facilitates the flow of the cleaning liquid and prevents the problem of dirt accumulating at the bottom of the cleaning object 5. The cleaning fixture of the present invention achieves multifunctional and flexible application for clamping of various sizes. Using the cleaning fixture of the present invention can effectively reduce residual dirt after cleaning, improve the cleaning quality, and thus improve the cleaning yield.

[0082] While the embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations may be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the claims. Furthermore, the present invention described herein may have other embodiments and may be implemented or carried out in a variety of ways.
