Currently, flow battery stacks are typically secured using a structure of screws, nuts, and springs. When the stack needs to be disassembled, the high spring force often damages the screw threads, making disassembly difficult and inefficient.

[0013] Furthermore, the auxiliary tooling for disassembling the fuel cell stack also includes a liquid collection tank disposed on the transfer platform, and the carrier is located in the liquid collection tank.

[0014] Furthermore, the support platform is provided with a clearance groove corresponding to the disassembly station to avoid the second transmission mechanism. The clearance groove is provided with a support component to support the second transmission mechanism. The support component includes a support seat in the clearance groove and a plurality of elastic support members spaced apart on the support seat. The second transmission mechanism is supported on the plurality of elastic support members. A transmission groove is connected to the outer side of the end of the transmission platform away from the disassembly station. The transmission groove is connected to the linear transmission mechanism. The transmission groove is provided with a clearance space to avoid the linear transmission mechanism.

[0015] Furthermore, the first transmission mechanism and / or the second transmission mechanism are smooth bars.

[0019] Compared with the prior art, one or more technical solutions in the embodiments of this utility model have at least one of the following beneficial effects:

[0020] The auxiliary tooling for disassembling the fuel cell stack in this embodiment only requires placing the fuel cell stack to be disassembled on the carrier. After the carrier is moved to the disassembly station on the disassembly platform by the linear transmission mechanism, the pressing mechanism drives the holding assembly to move toward the disassembly station. The holding assembly, in conjunction with the carrier, uses pre-tightening force to hold the fuel cell stack to be disassembled at the disassembly station. This overcomes the damage to the second screw threads caused by the spring force during fuel cell stack disassembly, which helps to reduce the disassembly difficulty of the second screw and second nut on the fuel cell stack and improve disassembly efficiency. At the same time, by using the holding assembly and the carrier to hold the fuel cell stack at the disassembly station with pre-tightening force, the overall force on the fuel cell stack can be more even during disassembly, effectively avoiding uneven force distribution during the removal of the second screw and spring on the fuel cell stack, which could lead to damage to the internal components of the fuel cell stack.

Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0044] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0045] Please refer to the following: Figures 1 to 8 The auxiliary tooling for disassembling the fuel cell stack provided in this embodiment of the invention will now be described. Please refer to the following references. Figure 1 , Figure 2 and Figure 3The auxiliary tooling for disassembling a fuel cell stack provided in this embodiment includes a disassembly stand 1, a support member 2, a linear transmission mechanism 3, a pressing assembly 4, and a pressing mechanism 5. The disassembly stand 1 has a disassembly station for operators to disassemble the fuel cell stack 50. The support member 2 is slidably mounted on the disassembly stand 1 along a first direction. The linear transmission mechanism 3 is mounted on the disassembly stand 1 and can drive the support member 2 to move along the first direction to the disassembly station on the disassembly stand 1. The pressing assembly 4 is slidably mounted on the disassembly stand 1 along a second direction. The pressing mechanism 5 is mounted on the disassembly stand 1 and connected to the pressing assembly 4. The pressing mechanism 5 can drive the pressing assembly 4 to move along the second direction toward the disassembly station, so that the pressing assembly 4, in conjunction with the support member 2, presses the fuel cell stack 50 at the disassembly station with a pre-tightening force. It should be noted that when the first direction is horizontal, the second direction can be vertical. Preferably, the second direction is perpendicular to the first direction, and the support member 2 can be, but is not limited to, a support platform that can support the fuel cell stack 50. The platform surface is parallel to the first direction and perpendicular to the second direction, which can improve the uniformity of force on the fuel cell stack 50 during disassembly.

[0046] When disassembling the fuel cell stack 50, the stack to be disassembled is first placed on the support member 2. Then, the linear transmission mechanism 3 moves the support member 2 to the disassembly station on the disassembly stand 1. Next, the pressure applying mechanism 5 is activated, driving the holding assembly 4 towards the disassembly station until the holding assembly 4, in conjunction with the support member 2, presses the fuel cell stack 50 at the disassembly station with a pre-tightening force, overcoming the spring force. The operator can then remove the second screw and second nut that serve as fasteners on the fuel cell stack 50 one by one, thus disassembling the fuel cell stack 50. After all the second screws and second nuts on the fuel cell stack 50 have been removed, the pressure applying mechanism 5 drives the holding assembly 4 to move away from the disassembly station, releasing the holding assembly 4 from its pressing effect on the fuel cell stack 50. Then, the linear transmission mechanism 3 moves the support member 2 from the disassembly station back to its initial position, making it convenient for the operator to remove the disassembled fuel cell stack 50 from the support member 2.

[0047] The auxiliary tooling for disassembling fuel cell stacks provided in this embodiment of the invention, compared with the prior art, only requires placing the fuel cell stack 50 to be disassembled on the carrier 2. After the linear transmission mechanism 3 drives the carrier 2 to move to the disassembly station on the disassembly stand 1, the pressing mechanism 5 drives the holding assembly 4 to move toward the disassembly station. Relying on the holding assembly 4 and the carrier 2 to press the fuel cell stack 50 to be disassembled at the disassembly station with a pre-tightening force, the damage to the second screw threads caused by the spring force during the disassembly of the fuel cell stack 50 can be overcome. This helps to reduce the disassembly difficulty of the second screw and second nut on the fuel cell stack 50 and improve disassembly efficiency. At the same time, by pressing the fuel cell stack 50 at the disassembly station with a pre-tightening force through the holding assembly 4 and the carrier 2, the overall force on the fuel cell stack 50 can be more even during the disassembly process, effectively avoiding uneven force during the disassembly of the second screw and spring on the fuel cell stack 50, which could lead to damage to the internal components of the fuel cell stack 50.

[0048] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the auxiliary tooling for disassembling the fuel cell stack further includes multiple columns 6 mounted on the disassembly stand 1, a holding assembly 4 slidably mounted on the multiple columns 6, and a pressure applying mechanism 5 fixedly mounted on the multiple columns 6. In this embodiment, by arranging multiple columns 6 parallel and spaced apart on the disassembly stand 1, and slidably mounting the holding assembly 4 on the multiple columns 6, when the pressure applying mechanism 5 drives the holding assembly 4 to move along the second direction, the multiple columns 6 can guide the holding assembly 4 to move along the second direction. This improves the stability and reliability of the movement of the holding assembly 4, and ensures that the holding assembly 4 applies or releases force evenly to the fuel cell stack 50 to be disassembled, making the overall force on the fuel cell stack 50 more uniform during disassembly. It should be noted that the axial direction of the multiple columns 6 is parallel to the second direction, and the number of columns 6 can be three, four, or more. The specific number of columns 6 can be reasonably set according to actual usage needs and is not limited here.

[0049] Please refer to the following: Figure 1 , Figure 2 and Figure 3In some embodiments, the holding assembly 4 includes a slider 41 slidably mounted on multiple columns 6 and a holding block 42 connected to the slider 41. A pressure applying mechanism 5 is connected to the slider 41. In this embodiment, the pressure applying mechanism 5 can drive the slider 41 to move along a second direction, which in turn drives the holding block 42 to move along the second direction, allowing the holding block 42 to cooperate with the carrier 2 to hold the fuel cell stack 50 to be disassembled at the disassembly station with a pre-tightening force. It should be noted that the slider 41 has sliding holes through which the columns 6 pass. Each column 6 slides in contact with the inner wall of the corresponding sliding hole. Through the sliding cooperation between each column 6 and the corresponding sliding hole, the slider 41 is slidably mounted on multiple columns 6, and the slider 41 can be guided to move along the second direction by the multiple columns 6. It should also be noted that, to reduce friction between the sliding hole and the column 6, a sliding sleeve can be provided inside the sliding hole. The sliding sleeve can be slidably fitted onto the column 6 along the axial direction of the column 6.

[0050] Please refer to the following: Figure 1 , Figure 2 and Figure 8 In some embodiments, the disassembly stand 1 includes a support frame 11 supporting the linear drive mechanism 3 and a support platform 12 supporting the pressure application mechanism 5. The support frame 11 and the support platform 12 are fixedly connected. The support platform 12 is provided with a disassembly station. The pressure holding assembly 4 is slidably disposed on the support platform 12 at the position corresponding to the disassembly station via multiple columns 6 in a second direction. The pressure application mechanism 5 is mounted on the support platform 12 via multiple columns 6. The linear drive mechanism 3 is mounted on the support frame 11. The auxiliary tooling for disassembling the fuel cell stack also includes a first transmission mechanism 9 disposed on the support frame 11, a second transmission mechanism 10 disposed on the support platform 12, and a transmission platform 40 for transmission between the first transmission mechanism 9 and the second transmission mechanism 10. The transmission platform 40 is connected to the linear drive mechanism 3. The carrier 2 is disposed on the transmission platform 40. The second transmission mechanism 10 is connected to the first transmission mechanism 9. In this embodiment, the transfer platform 40 equipped with the carrier 2 slides in contact with the support frame 11 via the first transfer mechanism 9, and the transfer platform 40 equipped with the carrier 2 slides in contact with the support platform 12 via the second transfer mechanism 10. The linear transmission mechanism 3 can drive the transfer platform 40 equipped with the carrier 2 to slide from the support frame 11 to the disassembly station of the support platform 12, or the linear transmission mechanism 3 can drive the transfer platform 40 equipped with the carrier 2 to slide from the disassembly station of the support platform 12 to the support frame 11, thereby realizing the movement and conveying of the fuel cell stack 50 along the first direction. It should be noted that the first transfer mechanism 9 can be, but is not limited to, a gravity conveyor, and the second transfer mechanism 10 can be, but is not limited to, a gravity conveyor. For example, the first transfer mechanism 9 can also be a belt conveyor or a roller conveyor, and the second transfer mechanism 10 can also be a belt conveyor or a roller conveyor.

[0051] Please refer to the following: Figure 1 , Figure 2Figures 6(a) and 6(b) show that in some embodiments, the auxiliary tooling for disassembling the fuel cell stack also includes a collection tank 20 disposed on the transfer platform 40, with the support member 2 located in the collection tank 20. During the disassembly of the fuel cell stack 50 held on the support member 2, the residual electrolyte inside the fuel cell stack 50 will collect in the collection tank 20, effectively preventing electrolyte pollution of the environment and corrosion of the equipment. It should be noted that, in order to ensure that the residual electrolyte inside the fuel cell stack 50 on the support member 2 flows into the collection tank 20, the projected area of ​​the support member 2 on the collection tank 20 is smaller than the area of ​​the collection tank 20. In other embodiments, to facilitate the collection or recycling of electrolyte, the collection tank 20 is provided with an outlet 30 for electrolyte outflow, and the outlet 30 is connected to the collection tank through a pipe.

[0052] Please refer to the following: Figure 1 , Figure 4 and Figure 5 In some embodiments, the support platform 12 is provided with a clearance groove 13 at the position corresponding to the disassembly station to avoid the second transmission mechanism 10. The clearance groove 13 is provided with a support component 7 for supporting the second transmission mechanism 10. The support component 7 includes a support seat 71 disposed in the clearance groove 13 and a plurality of elastic support members 72 spaced apart on the support seat 71. The second transmission mechanism 10 is supported on the plurality of elastic support members 72. Please refer to Figure 6(b) and... Figure 9A transmission groove 401 is connected to the outer side of the end of the transmission platform 40 away from the disassembly station. The transmission groove 401 is connected to the linear transmission mechanism 3. An avoidance space is provided above the inside of the transmission groove 401 to avoid the linear transmission mechanism 3. The transmission groove 401 does not contact the first transmission mechanism 9. In this embodiment, when the linear transmission mechanism 3 drives the transmission platform 40 to move onto the second transmission mechanism 10, and the pressing mechanism 5 drives the holding assembly 4 to press against the fuel cell stack 50 to be disassembled on the carrier 2, the avoidance groove 13 of the support platform 12 avoids the second transmission mechanism 10 due to the contraction and buffering of the elastic support 72. This causes the transmission platform 40 supporting the carrier 2 to drop a certain height, and the transmission platform 40 can then contact the supporting planes 14 on both sides of the avoidance groove 13 on the support platform 12. This allows the supporting planes 14 on both sides of the avoidance groove 13 on the support platform 12 to support the transmission platform 40, reducing the force on the second transmission mechanism 10 and effectively preventing the second transmission mechanism 10 from being damaged due to excessive pressure. When the holding assembly 4 releases its holding effect on the disassembled fuel cell stack 50 on the carrier 2, the elastic support 72 returns to its original state, thus lifting the second transmission mechanism 10. This causes the transmission platform 40, supported on the second transmission mechanism 10, to rise to a certain height and disengage from the support planes 14 on both sides of the clearance groove 13 on the support platform 12, ensuring that the transmission platform 40 can move seamlessly between the first transmission mechanism 9 and the second transmission mechanism 10. It should be noted that the elastic support 72 can be, but is not limited to, a spring. The number of elastic support 72 can be one, two, or more. The specific number of elastic support 72 can be reasonably set according to actual usage needs and is not limited here. Since the transmission groove 401 is located on the outside of the transmission platform 40, the transmission platform 40 can be transmitted to the second transmission mechanism 10 through the transmission groove 401. Because the upper part of the transmission groove 401 has a clearance space to avoid the linear transmission mechanism 3, when the transmission platform 40 descends on and together with the second transmission mechanism 10, the transmission groove 401 connected to the linear transmission mechanism 3 can descend synchronously with the transmission platform 40. When the holding assembly 4 releases its holding effect on the electrode stack 50 on the bearing member 2, the elastic support member 72 returns to its original state and lifts the second transmission mechanism 10, so that when the transmission platform 40 supported on the second transmission mechanism 10 rises to a certain height, the transmission groove 401 rises synchronously with the transmission platform 40. The transmission groove 401 can be made of I-beams and welded to the transmission platform 40.

[0053] Please refer to the following: Figure 1 , Figure 2 , Figure 7 and Figure 9In some embodiments, the linear transmission mechanism 3 includes a first screw 32 rotatably mounted on the disassembly frame 1, a first nut 33 screwed onto the first screw 32, and a rotary handle 31 connected to the first screw 32. The first nut 33 has a transmission block 331, and the first nut 33 is slidably connected to the support frame 11. The transmission block 331 is connected to the transmission groove 401 and can drive the carrier 2 to move along a first direction. A clearance space is provided above the transmission groove 401 to accommodate the transmission block 331. The axial direction of the first screw 32 is parallel to the first direction. By rotating the rotary handle 31, the first nut 33 and the first screw 32, under the action of the thread, can drive the carrier 2 mounted on the transmission table 40 to move along the axial direction of the first screw 32. Figure 1 As shown, the linear transmission mechanism 3 is located between the two first transmission mechanisms 9. Figure 9 This diagram illustrates the movement of the transmission platform 40 towards the disassembly station driven by the first nut 33. Since the transmission platform 40 is slidably mounted on the two first transmission mechanisms 9, and the transmission groove 401 has a clearance space above it to avoid the transmission block 331, the top of the transmission block 331 does not contact the top of the transmission groove 401. As the transmission block 331 moves towards the disassembly station under the action of the first nut 33, the end of the transmission block 331 facing the disassembly station presses against the transmission groove 401, causing the transmission groove 401 and the transmission platform 40 to move. When the transmission platform 40 descends on the second transmission mechanism 10 and together with it, the clearance space inside the transmission groove 401 allows the transmission groove 401 to descend along with the transmission platform 40. When the transmission block 331 moves away from the disassembly station under the action of the first nut 33, the end of the transmission block 331 away from the disassembly station presses against the transmission groove 401, causing the transmission groove 401 and the transmission platform 40 to move. It should be noted that the linear transmission mechanism 3 can also be replaced by a linear module, which automatically drives the first screw 32 to rotate, so that the first nut 33 drives the transmission table 40 to move along the axial direction of the first screw 32.

[0054] Please refer to the following: Figure 3 , Figure 4 and Figure 5In some embodiments, the auxiliary tooling for disassembling the fuel cell stack further includes a stop assembly 8 for stopping the second transmission mechanism 10. The stop assembly 8 includes a first stop 81 located at one end of the second transmission mechanism 10 and a second stop 82 located at the other end of the second transmission mechanism 10. When the holding assembly 4 releases the holding effect on the fuel cell stack 50 on the carrier 2, the elastic support 72 returns to its original state to support the second transmission mechanism 10. The first stop 81 stops and limits one end of the second transmission mechanism 10, while the second stop 82 stops and limits the other end of the second transmission mechanism 10, so that the transmission plane of the second transmission mechanism 10 is flush with the transmission plane of the first transmission mechanism 9, thereby ensuring that the transmission platform 40 can move seamlessly between the first transmission mechanism 9 and the second transmission mechanism 10.

[0055] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In some embodiments, the pressure applying mechanism 5 includes a support base 51 supported and fixed on the disassembly stand 1 and a linear drive mechanism 52 mounted on the support base 51. The linear drive mechanism 52 is connected to the holding assembly 4. The linear drive mechanism 52 includes a linear module, an electric cylinder, an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. Specifically, the support base 51 is supported and fixed on the support platform 12 of the disassembly stand 1 by multiple columns 6. The linear drive mechanism 52 is connected to the slider 41 of the holding assembly 4. The linear drive mechanism 52 can drive the slider 41 to move in a second direction. The slider 41 then drives the holding block 42 to move in the second direction, so that the holding block 42 can cooperate with the carrier 2 to press the fuel cell stack 50 to be disassembled at the disassembly station with a pre-tightening force.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
