Description

Technical Field

[0001] This utility model relates to a stacking fixture for electrolytic cell stacks. Background Technology

[0002] An electrolytic cell stack mainly consists of membrane electrode assemblies, electrode plates, top and bottom end plates, and fastening screws. In actual assembly, it is generally done manually. Since manual stacking relies on visual estimation to determine position, this method is difficult to guarantee accuracy. The bottom end plate is very heavy and difficult to place precisely, yet it needs to be accurately positioned in the center of the press. Any eccentricity will cause uneven pressure, affecting assembly and even the sealing performance of the stack after assembly, ultimately impacting the battery's output performance. Therefore, manual stacking is both inefficient and inaccurate. Furthermore, the lack of positioning for the top end plate and individual cells poses safety hazards during operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of low efficiency and poor precision in the existing technology that relies on manual stacking, and to provide an electrolytic cell stacking tool.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides an electrolytic cell stacking fixture, which includes a base, a fixing block and a locking block. The locking block and the fixing block are disposed on the base, and a receiving cavity is formed between the locking block and the fixing block, so that the receiving cavity is located in the middle area of ​​the base. The receiving cavity is used to place the cell stack base plate, and the locking block can slide along the surface of the base to fix the cell stack base plate in the receiving cavity.

[0006] In this solution, locking blocks and fixing blocks are installed on the base of the electrolytic cell stack loading fixture. A receiving cavity for placing the cell stack base plate is formed between the fixing block and the locking block, and the receiving cavity is located in the middle area of ​​the base. After the cell stack base plate is placed into the receiving cavity, it can be coarsely positioned by being pressed against the fixing block. Then, the locking block slides along the surface of the base to provide a lateral force to the cell stack base plate, thereby pushing the cell stack base plate against the fixing block to achieve precise positioning. At the same time, the cell stack base plate is locked between the locking block and the fixing block, achieving centered fixation of the cell stack base plate. This prevents eccentricity during subsequent assembly using a press and avoids affecting the performance of the cell stack.

[0007] Preferably, the locking block includes a first locking block and a second locking block. The first locking block is fixed on the base, and the second locking block is disposed between the first locking block and the fuel cell base plate. The first locking block and the second locking block each have mutually fitting inclined surfaces facing the fuel cell base plate. The second locking block can slide relative to the first locking block along the inclined surfaces.

[0008] In this design, a first locking block is fixedly mounted on the base, and a second locking block is embedded between the first locking block and the fuel cell stack base plate. Since both the first and second locking blocks have inclined surfaces that fit against each other and face the fuel cell stack base plate, the second locking block can slide downwards along the inclined surfaces while simultaneously sliding laterally towards the fuel cell stack base plate. This lateral sliding of the second locking block achieves the positioning and fixing of the fuel cell stack base plate. This structure simplifies the positioning and fixing of the fuel cell stack base plate, further improving stacking efficiency.

[0009] Preferably, both the first locking block and the second locking block are provided with a first bolt hole, the base is provided with a second bolt hole at a position corresponding to the first locking block, and the base is provided with a second bolt hole at a position corresponding to the second locking block, wherein the second bolt hole is an elongated hole.

[0010] In this design, the first bolt hole on the first locking block connects with the first bolt hole on the base to fix the first locking block. The first bolt hole on the second locking block connects with the second bolt hole on the base. Since the second locking block needs to move laterally relative to the first locking block, the space requirement for displacement can be met by making the second bolt hole an elongated hole. With this structure, the second locking block can slide along the inclined plane by tightening the bolts, further simplifying operation and improving stacking efficiency.

[0011] Preferably, the fixing block and / or the locking block are detachably connected to the base.

[0012] In this solution, by detachably connecting the fixing block or locking block to the base, the distance between the locking block or fixing block can be adjusted, thereby changing the size of the receiving cavity for placing the fuel cell base plate, thus adapting to fuel cell base plates of different sizes and improving the applicability of the tooling.

[0013] Preferably, the electrolytic cell stacking fixture further includes a plurality of side positioning components, which are distributed around the periphery of the receiving cavity. Each side positioning component includes a chassis, a first support frame, and a second support frame. The first support frame is disposed on the chassis, and the second support frame is disposed on the side wall of the first support frame and extends outward toward the receiving cavity from the side surface of the first support frame. The second support frame is used to abut against the cell stack to position the cell stack.

[0014] In this design, side positioning components are arranged around the periphery of the receiving cavity. The first support frame of each side positioning component supports a second support frame. The position of the battery stack is determined by the distance the second support frame extends beyond the side wall of the first support frame towards the receiving cavity. The second support frames of several side positioning components form a space for placing the battery stack in the height direction of the receiving cavity. Therefore, this structure can effectively position the battery stack, improving installation efficiency and accuracy.

[0015] Preferably, a third support frame is provided on the second support frame, the top of the third support frame protrudes from the top of the second support frame, and the top of the third support frame is provided with a placement surface for placing the top plate of the fuel cell stack.

[0016] In this scheme, by setting a third support frame and making its top exceed the top of the second support frame, the placement height of the top plate can be higher than that of the fuel cell stack. On the one hand, this can provide support for the top plate of the fuel cell stack and improve the safety of stacking; on the other hand, it can place the top plate of the fuel cell stack at a height higher than that of the fuel cell stack to meet the needs of stacking.

[0017] Preferably, the second support frame has a guide rail on its side wall in the vertical direction, and the third support frame is disposed on the guide rail.

[0018] In this solution, by setting a vertical guide rail on the side wall of the second support frame, the third support frame can be moved vertically relative to the second support frame along the guide rail, thereby further adjusting and raising the height of the third support frame, so that the tooling can be matched with fuel cell stacks of different heights, further improving the applicability of the tooling.

[0019] Preferably, the portion of the placement surface near the first support frame extends upward to form a protrusion, which is used to snap the top plate of the fuel cell stack onto the top of the third support frame.

[0020] In this design, by setting a protrusion on the placement surface, the top plate of the fuel cell stack can be snapped onto the third support frame, preventing the top plate of the fuel cell stack from slipping and causing damage, thus improving the safety of stacking.

[0021] Preferably, the side positioning component further includes a guide block, the guide block being disposed on one side of the chassis and the side positioning component being tightly attached to the guide block;

[0022] And / or, the chassis is provided with positioning holes, and the chassis is connected to the base by pins passing through the positioning holes.

[0023] In this design, a guide block is used to hold the side positioning component close to it, and the position of the guide block is used to determine the position of the side positioning component. Positioning holes are provided on the chassis to further determine the position of the side positioning component, thereby improving the accuracy of the fuel cell stack top plate installation. This structure improves the accuracy of the side positioning component's position, thus improving the accuracy of the fuel cell stack top plate installation.

[0024] Preferably, a reinforcing rib is provided between the chassis and the first support frame.

[0025] In this design, by setting reinforcing ribs between the chassis and the first support frame, the support strength of the first support frame can be improved, thereby improving the stability of the stack top plate during stacking.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] This utility model discloses an electrolytic cell stacking fixture. A locking block and a fixing block are installed on the base of the fixture, forming a cavity between the locking and fixing blocks to accommodate the cell stack base plate. The cavity is located in the middle of the base. After the cell stack base plate is placed in the cavity, it is roughly positioned against the fixing block. Then, the locking block slides along the base surface, providing a lateral force to the base plate, thus precisely positioning it against the fixing block. Simultaneously, the base plate is locked between the locking and fixing blocks, achieving centered fixation. This prevents eccentricity during subsequent press assembly, avoiding any impact on the cell stack's performance. Attached Figure Description

[0058] Top plate of fuel cell stack 8 Detailed Implementation

[0059] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0060] This embodiment provides an electrolytic cell stacking fixture 100, such as... Figures 1-7 As shown, it includes a base 1, a fixing block 2 and a locking block 3. The locking block 3 and the fixing block 2 are disposed on the base 1, and a receiving cavity 4 is formed between the locking block 3 and the fixing block 2, so that the receiving cavity 4 is located in the middle area of ​​the base 1. The receiving cavity 4 is used to place the fuel cell base plate 5. The locking block 3 can slide along the surface of the base 1 to fix the fuel cell base plate 5 in the receiving cavity 4.

[0061] Thus, by setting a locking block 3 and a fixing block 2 on the base 1 of the electrolytic cell stack loading fixture 100, a receiving cavity 4 for placing the cell stack base plate 5 is formed between the fixing block 2 and the locking block 3, and the receiving cavity 4 is located in the middle area of ​​the base 1. After the cell stack base plate 5 is placed into the receiving cavity 4, it can be roughly positioned by being close to the fixing block 2. Then, by sliding the locking block 3 along the surface of the base 1, a lateral force is provided to the cell stack base plate 5, thereby pushing the cell stack base plate 5 against the fixing block 2 to achieve precise positioning. At the same time, the cell stack base plate 5 is locked between the locking block 3 and the fixing block 2, so that the cell stack base plate 5 is centered and fixed, so that no eccentricity will occur during subsequent assembly using the press, thus avoiding affecting the performance of the cell stack.

[0062] In this embodiment, the fixing block 2 and the locking block 3 can be one or more pieces. Preferably, there are multiple fixing blocks 2 and locking blocks 3, and the fixing blocks 2 and locking blocks 3 form the outer contour of the fuel cell base plate 5, that is, the receiving cavity 4 is the outer contour of the fuel cell base plate 5. The specific number of fixing blocks 2 and locking blocks 3 can be adjusted according to the actual size of the fuel cell base plate 5, and this embodiment does not limit it. The locking block 3 can slide along the surface of the base 1, which means that the locking block 3 can move laterally along the chassis 61. When the chassis 61 is placed horizontally, it moves in the horizontal direction.

[0063] Specifically, such as Figure 2 As shown, the locking block 3 includes a first locking block 31 and a second locking block 32. The first locking block 31 is fixed on the base 1, and the second locking block 32 is disposed between the first locking block 31 and the fuel cell base plate 5. The first locking block 31 and the second locking block 32 each have mutually fitting inclined surfaces 33 facing the fuel cell base plate 5. The second locking block 32 can slide relative to the first locking block 31 along the inclined surface 33.

[0064] Thus, by fixing the first locking block 31 to the base 1 and embedding the second locking block 32 between the first locking block 31 and the fuel cell stack base plate 5, and since the first locking block 31 and the second locking block 32 are provided with inclined surfaces 33 that fit together and face the fuel cell stack base plate 5, the second locking block 32 can slide downward along the inclined surface 33 while simultaneously sliding laterally toward the fuel cell stack base plate 5. This lateral sliding of the second locking block 32 achieves the positioning and fixing of the fuel cell stack base plate 5. This structure simplifies the positioning and fixing of the fuel cell stack base plate 5, further improving stacking efficiency.

[0065] In this embodiment, first bolt holes 34 are provided on both the first locking block 31 and the second locking block 32. The base 1 has a first bolt hole 34 at a position corresponding to the first locking block 31, and a second bolt hole 35 at a position corresponding to the second locking block 32. The second bolt hole 35 is an elongated hole. An elongated hole refers to a hole with a rectangular or oblong opening, allowing the bolt to move laterally during downward screwing. The first bolt hole 34 on the first locking block 31 connects with the first bolt hole 34 on the base 1 to fix the first locking block 31. The first bolt hole 34 on the second locking block 32 connects with the second bolt hole 35 on the base 1. Since the second locking block 32 needs to move laterally relative to the first locking block 31, making the second bolt hole 35 an elongated hole satisfies the space requirements for the second locking block 32's movement. With this structure, the second locking block 32 can slide along the inclined surface 33 by tightening the bolt, further simplifying the operation and improving stacking efficiency.

[0066] Specifically, the fixing block 2 and / or locking block 3 are detachably connected to the base 1.

[0067] Thus, by detachably connecting the fixing block 2 or the locking block 3 to the base 1, the distance between the locking block 3 or the fixing block 2 can be adjusted, thereby changing the size of the receiving cavity 4 for placing the fuel cell base plate 5, so as to adapt to fuel cell base plates 5 of different sizes and improve the applicability of the tooling.

[0068] In this embodiment, the fixing block 2 and the locking block 3 can be connected to the base 1 by screw holes or bolts, or by pin holes. In other embodiments, those skilled in the art can also use other detachable connection methods.

[0069] Specifically, such as Figure 3 and Figure 4 As shown, the electrolytic cell stack assembly 100 also includes several side positioning components 6. The several side positioning components 6 are distributed around the periphery of the receiving cavity 4. The side positioning components 6 include a chassis 61, a first support frame 62 and a second support frame 63. The first support frame 62 is disposed on the chassis 61, and the second support frame 63 is disposed on the side wall of the first support frame 62 and extends out of the side surface of the first support frame 62 toward the receiving cavity 4. The second support frame 63 is used to abut against the cell stack 7 to position the cell stack 7.

[0070] Thus, as Figure 6As shown, by arranging side positioning components 6 around the periphery of the receiving cavity 4, the first support frame 62 of the side positioning components 6 provides support for the second support frame 63. The position of the battery stack 7 is determined by the distance by which the second support frame 63 extends outward from the side wall of the first support frame 62 toward the receiving cavity 4. A space for placing the battery stack 7 is formed between the second support frames 63 of several side positioning components 6 in the height direction of the receiving cavity 4. Therefore, this structure can effectively position the battery stack 7, improving installation efficiency and accuracy.

[0071] In this embodiment, as Figure 5 As shown, the side positioning component 6 along the periphery of the receiving cavity 4 means that the side positioning component 6 is disposed outside the receiving cavity 4 and along the boundary of the receiving cavity 4. The first support frame 62 can be disposed vertically or at an angle on the chassis 61. Preferably, the first support frame 62 is disposed vertically on the chassis 61, which can provide better support. The second support frame 63 preferably extends perpendicularly to the first support frame 62, so that the battery stack 7 can be directly against the second support frame 63, which facilitates precise positioning of the battery stack 7. The number of side positioning components 6 can be one or more, preferably multiple and distributed, so as to form a more complete space for placing the battery stack 7 in the height direction of the receiving cavity 4. The specific number can be adjusted according to the actual size of the battery stack, which is not limited in this embodiment.

[0072] Specifically, such as Figure 7 As shown, a third support frame 64 is provided on the second support frame 63. The top of the third support frame 64 protrudes from the top of the second support frame 63. The top of the third support frame 64 is provided with a placement surface 641, which is used to place the top plate 8 of the fuel cell stack.

[0073] Thus, by setting up a third support frame 64 and making its top exceed the top of the second support frame 63, the placement height of the top plate can be higher than that of the fuel cell stack 7. On the one hand, this can provide support for the top plate 8 of the fuel cell stack, improving the safety of stacking; on the other hand, it can place the top plate 8 of the fuel cell stack at a height higher than that of the fuel cell stack 7 to meet the needs of stacking.

[0074] In this embodiment, a vertical guide rail can be provided on the side wall of the second support frame 63, and the third support frame 64 is disposed on the guide rail. By providing a vertical guide rail on the side wall of the second support frame 63, the third support frame 64 can move vertically relative to the second support frame 63 along the guide rail, thereby further adjusting and raising the height of the third support frame 64. This allows the fixture to be matched with fuel cell stacks of different heights, further improving the applicability of the fixture. In other embodiments, the guide rail can also be disposed on the first support frame 62.

[0075] Specifically, such as Figure 3 and Figure 7As shown, the portion of the placement surface 641 near the first support frame 62 extends upward to form a protrusion 642, which is used to snap the top plate 8 of the fuel cell stack to the top of the third support frame 64.

[0076] Thus, by providing a protrusion 642 on the placement surface 641, the top plate 8 of the fuel cell stack can be snapped onto the third support frame 64, preventing the top plate 8 of the fuel cell stack from slipping and causing damage, thereby improving the safety of the stacking process.

[0077] In this embodiment, the protrusion 642 refers to the portion of the placement surface 641 that extends upward near the first support frame 62, causing the top plate 8 of the fuel cell stack to abut against the protrusion 642, thereby fixing the position of the top plate 8. Preferably, the protrusion 642 extends upward perpendicular to the placement surface 641, which is beneficial for accurately positioning the top plate 8 of the fuel cell stack.

[0078] Specifically, such as Figures 4-7 As shown, the side positioning component 6 also includes a guide block 65, which is disposed on one side of the chassis 61 and the side positioning component 6 is tightly attached to the guide block 65; and / or, the chassis 61 is provided with a positioning hole 66, and the chassis 61 is connected to the base 1 by a pin passing through the positioning hole 66.

[0079] Thus, by setting the guide block 65, the side positioning component 6 is tightly attached to the guide block 65, and the position of the side positioning component 6 is determined by the position of the guide block 65. By setting the positioning hole 66 on the chassis 61, the position of the side positioning component 6 can be further determined, further improving the installation accuracy of the fuel cell stack top plate 8. With this structure, the accuracy of the position of the side positioning component 6 can be improved, thereby improving the installation accuracy of the fuel cell stack top plate 8.

[0080] In this embodiment, the guide block 65 can be one or more pieces. Preferably, there are two guide blocks 65. The positions of the two guide blocks 65 are determined on the base 1 of the fixture, and the side positioning component 6 is set tightly between the two guide blocks 65 to more accurately position the side positioning component 6. The base 61 of the side positioning component 6 has positioning holes 66, and the base 1 of the fixture also has corresponding positioning holes 66. The components are connected by pins to achieve the effect of auxiliary positioning.

[0081] Specifically, a reinforcing rib 67 is provided between the chassis 61 and the first support frame 62.

[0082] Thus, by setting a reinforcing rib 67 between the chassis 61 and the first support frame 62, the support strength of the first support frame 62 can be improved, thereby improving the stability of the stack top plate 8 during stacking.

[0083] In this embodiment, a reinforcing rib 67 may also be provided between the first support frame 62 and the second support frame 63.

[0084] The electrolytic cell stack loading fixture 100 is used as follows: First, the cell stack base plate 5 is manually placed on the base 1, and the fixing block 2 is used for rough positioning. Then, the locking block 3 is used to lock the base plate 5 and simultaneously perform fine positioning so that the cell stack base plate 5 is located in the middle position of the base 1. Next, the side positioning component 6 is installed, and the guide block 65 and positioning hole 66 are used to determine the position. The cell stack 7 is manually positioned and placed into the fixture using the side positioning component 6. After checking the number of cell stack 7 and placing them all, the cell stack top plate 8 is manually placed on the side positioning component 6 and positioned. After the installation and fixing are completed, the side positioning component 6 is removed and the locking block 3 is loosened. Finally, the electrolytic cell stack is lifted out.

[0085] The advantages of using the electrolytic cell stack assembly fixture 100 are that it improves safety during electrolytic cell stack assembly and ensures consistency in the position of the stack cells 7, thereby enhancing the sealing between each cell 7 and improving the overall performance of the electrolytic cell stack. Furthermore, the fixture is easy to operate, improving the efficiency and accuracy of manual stacking.
