[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present 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.

[0033] like Figures 1 to 5As shown, the repair and pressing equipment of the present invention includes: a support component 10, the support component 10 is arranged on a support base, and a pressing detection area 110 is arranged above the support component 10; a pressing component 20, the pressing component 20 is arranged on the support component 10 and is at least partially located above the pressing detection area 110, so as to press or depress the battery stack located in the pressing detection area 110; and a detection component 30, the detection component 30 is arranged on the support component 10 and is at least partially located in the pressing detection area 110, so as to detect the battery stack after pressing.

[0034] In this way, the repair and pressing equipment of the present invention integrates the pressing component 20 and the detection component 30 on the same equipment and is located above the support component 10, so that the key processes such as disassembly of the battery stack, replacement of the membrane electrode and bipolar plate, pressing and airtightness testing are integrated into the same equipment, and the airtightness test is performed immediately after the battery stack is pressed, which can instantly verify the performance of the battery stack, ensure the pressing effect, and avoid ineffective work in subsequent processes, such as manual tightening and transportation, thereby saving resources and time, avoiding the need to transport the battery stack between different processes, significantly improving production efficiency, reducing the labor intensity of operators, and improving production rhythm; more effectively reducing the damage and contamination that the battery stack may suffer during the transportation process, improving the quality and consistency of the finished product of the battery stack, especially for large battery stacks, avoiding problems such as decreased sealing performance that may be caused during complex transportation processes, and efficiently solving the problems of multi-process decentralized processing of fuel cell stacks in the prior art, resulting in waste of production space, low transportation efficiency and risk of battery stack damage.

[0035] Preferably, the repair and pressing equipment of the present invention can move the stacked battery stack to the pressing inspection area 110 to press the stacked battery stack, and can also depressurize the unqualified battery stack after pressing in the pressing inspection area 110.

[0036] like Figure 2 As shown, the detection component 30 includes a detection plate 310, which is slidably disposed on the support component 10. A plurality of detection channels 320 are disposed on the detection plate 310. Each detection channel 320 includes a detection inlet and a detection outlet. The detection inlet is used to connect with an external supply component, and the detection outlet is used to communicate with the battery stack located on the detection plate 310, so as to introduce a variety of detection media into the battery stack through the plurality of detection channels 320 for detecting the air tightness of the battery stack after press-fitting. Through the plurality of detection channels 320 disposed on the detection plate 310, the detection component 30 can sequentially or simultaneously introduce one or different types of detection media, such as compressed air, hydrogen or inert gas, into the battery stack, so as to comprehensively evaluate the air tightness of the battery stack under different conditions and ensure its reliability and safety in the actual working environment.

[0037] Preferably, each detection inlet and detection outlet of each detection channel 320 in the present invention is provided with a sealing ring to cooperate with the detection plate 310 and the protrusions on the bottom plate of the battery stack to achieve sealing of the battery stack.

[0038] Preferably, the multiple detection channels 320 include: a hydrogen detection channel 321, the detection inlet of the hydrogen detection channel 321 is the hydrogen inlet 3211, and the detection outlet of the hydrogen detection channel 321 is the hydrogen outlet 3212; an air detection channel 322, the detection inlet of the air detection channel 322 is the air inlet 3221, and the detection outlet of the air detection channel 322 is the air outlet 3222; a water detection channel 323, the detection inlet of the water detection channel 323 is the water inlet 3231, and the detection outlet of the water detection channel 323 is the water outlet 3232. By using hydrogen, air and water as detection media, the equipment can comprehensively evaluate the air tightness and water tightness of the fuel cell stack under different working environments. The hydrogen detection channel 321 focuses on the air tightness of the hydrogen circulation system, the air detection channel 322 can be used to detect the sealing performance in a non-fuel environment, and the water detection channel 323 is aimed at the water system of the fuel cell stack to ensure that it will not leak under water partial pressure; the design of multiple detection channels 320 in the present invention makes the repair and pressing equipment more flexible during maintenance and optimization.

[0039] like Figure 3 As shown, the repair press-fitting equipment includes a limit assembly 40, which is arranged above the detection assembly 30 and fixedly connected to the detection assembly 30. The limit assembly 40 includes a limit space 410 for limiting the stack, and the size of the limit space 410 is adjustable. The adjustable design of the limit space 410 can accurately adapt to fuel cell stacks of different sizes and models, ensuring that the stack can be stably maintained in the optimal position during the press-fitting and testing process, avoiding improper press-fitting or inaccurate test results caused by size mismatch, and enhancing the adaptability of the equipment to a variety of stacks.

[0040] Preferably, the fuel cell stack of the present invention needs to be fixed in the limiting assembly 40 during the disassembly and press-assembly process before operation can begin, so as to prevent the entire stack from deforming.

[0041] Preferably, the repair and pressing equipment includes: two first limiting components 420, the two first limiting components 420 are arranged on the detection plate 310 at intervals along the length direction of the detection plate 310 of the detection assembly 30, and at least a part of the first limiting components 420 is movably arranged in a direction close to or away from the limiting space 410; two second limiting components 430, the two second limiting components 430 are arranged at intervals along the width direction of the detection plate 310, and at least a part of the second limiting components 430 is movably arranged in a direction close to or away from the limiting space 410. The adjustable movement of the first limiting components 420 and the second limiting components 430 enables the equipment to accurately align fuel cell stacks of different sizes, and can provide limiting in both the length direction and the width direction, thereby ensuring the stable state of the stack during detection and pressing, ensuring the physical stability of the stack during high-voltage testing, pressing and transportation, and avoiding the displacement or overturning of the stack due to external force or improper operation, thereby effectively improving the operational safety of the production site and reducing potential industrial accidents.

[0042] Preferably, each first limiting component 420 includes a fixed plate 421, a telescopic part 422 and a moving part 423 which are connected in sequence along a direction close to the limiting space 410. The fixed plate 421 is fixedly connected to the detection plate 310, and the telescopic part 422 is telescopically arranged along a direction close to or away from the limiting space 410 to drive the moving part 423 to adjust the length of the limiting space 410. The telescopic characteristics of the telescopic part 422 allow the moving part 423 to be precisely adjusted in a direction close to or away from the limiting space 410, thereby accurately controlling the length of the limiting space 410 and ensuring that battery stacks of different sizes can be properly limited and aligned to prevent them from displacement during detection and pressing.

[0043] Preferably, each second limiting component 430 includes two rotating parts 431, and the two rotating parts 431 are respectively rotatably mounted on the fixed plates 421 of the two first limiting components 420 to rotate in a direction close to or away from the limiting space 410. The rotation characteristics of the rotating parts 431 allow the second limiting component 430 to dynamically adjust the size of the limiting space 410 along the width direction, so as to adapt to battery stacks of different widths, and then finely adjust the position of the battery stack to ensure the best alignment of the battery stack in the limiting space 410, thereby improving the flexibility of the equipment.

[0044] Specifically, the moving part 423 includes a first limiting column 4231, which is arranged perpendicular to the detection plate 310; and / or the rotating part 431 includes a connecting door 4311 and a second limiting column 4312 installed on the side of the connecting door 4311 close to the limiting space 410, and the second limiting column 4312 is arranged perpendicular to the detection plate 310; the design of the first limiting column 4231 and the second limiting column 4312 can achieve precise limiting of the battery stack and ensure its stability in the length and width directions. The setting of the first limiting column 4231 and the second limiting column 4312 perpendicular to the detection plate 310 effectively prevents lateral displacement of the battery stack and improves the accuracy and reliability during the airtightness test and pressing process.

[0045] In the present invention, the first limiting column 4231 is connected to the telescopic member 422, so that the first limiting column 4231 can adjust the length of the limiting space 410 under the drive of the telescopic member 422; and the second limiting column 4312 is installed on the rotatable connecting door 4311. Through the adjustment of the connecting door 4311, the width of the limiting space can be flexibly changed, so as to quickly adapt to battery stacks of different sizes, thereby improving the production flexibility of the equipment.

[0046] Furthermore, each second limiting component 430 includes a rotating lock 432, one end of which is connected to one of the two rotating members 431, and the other end of the rotating lock 432 is used to connect to or separate from the other of the two rotating members 431 to lock or unlock the positions of the two rotating members 431.

[0047] The use of the rotating lock 432 provides a locking and unlocking function for the position of the rotating member 431. When the rotating lock 432 is in a locked state, it ensures that when the battery stack is pressed, the rotating lock 432 can be connected to both rotating members 431 to fix the position of the battery stack. When the rotating lock 432 is in an unlocked state, the rotating lock 432 is connected to one rotating member 431 and separated from the other rotating member 431. When the detection component 30 is located in the rework area 120 for manual stacking of battery stacks, the position of the rotating member 431 can be quickly adjusted to adapt to battery stacks of different sizes, thereby improving the level of safe operation, simplifying the operation process, and reducing the difficulty of operation.

[0048] like Figure 4As shown, the press-fitting assembly 20 includes: a press-fitting support body 210, which is arranged above the support assembly 10, and the press-fitting support body 210 includes a accommodating space 220 located above the press-fitting detection area 110; a pressure head 230, which is arranged in the accommodating space 220 and located above the battery stack, and a driving component 240, wherein the driving component 240 is arranged on the press-fitting support body 210 and is driven and connected to the pressure head 230 to drive the pressure head 230 to move in a vertical direction to tighten or loosen the battery stack. Through the driving connection between the driving component 240 and the pressure head 230, the lifting and lowering of the pressure head can be accurately controlled, thereby realizing accurate tightening or loosening of the battery stack, so that the battery stack reaches the required height, ensuring close contact between the internal components of the battery stack such as the membrane electrode and the bipolar plate, and improving the performance and reliability of the battery stack.

[0049] The design of the accommodation space 220 above the press-fit support body 210 in the present invention provides sufficient operational flexibility to accommodate fuel cell stacks of different sizes and stacking heights, which enables the device to handle fuel cell stacks of different models.

[0050] like Figure 1 As shown, a rework area 120 is arranged above the support component 10, and the rework area 120 is spaced apart from the press-fitting inspection area 110; a slide rail assembly 130 is also arranged on the support component 10, and the slide rail assembly 130 extends between the rework area 120 and the press-fitting inspection area 110, and a plurality of slider assemblies are arranged below the inspection component 30, and the plurality of slider assemblies are spaced apart on the slide rail assembly 130, so that the inspection component 30 can be movably arranged on the slide rail assembly 130, and the battery stack located on the inspection component 30 can be switched between the press-fitting inspection area 110 and the rework area 120; the separation design of the rework area 120 and the press-fitting inspection area 110 allows the battery stack to efficiently switch between the two areas, so that the rework operation and the press-fitting inspection can be carried out independently and orderly, the production process is optimized, the production interruption time is reduced, and the production efficiency is improved; and the combined use of the slide rail assembly 130 and the slider assembly provides smooth movement of the inspection component 30, so that the transportation operation of the battery stack is more flexible and convenient. Operators can easily move the battery stack from one area to another without interrupting the production process, which simplifies the operation process and reduces the difficulty of operation.

[0051] like Figure 5As shown, the repair and pressing equipment also includes: a protective component 50 and an operating panel 60. The protective component 50 is covered on the supporting component 10, and the operating panel 60 is installed on the protective component 50. The cover design of the protective component 50 forms a closed or semi-closed working environment, which effectively isolates the operating part of the equipment from the external environment, reduces the risk of accidental contact between the operator and the moving parts or high-voltage parts, and improves the operating safety. In addition, the installation position of the operating panel 60 is designed on the protective component, which is convenient for the operator to operate the equipment within a safe distance, further enhancing safety.

[0052] like Figure 5 As shown, the repair and pressing equipment also includes: a placement table 70, which is arranged on one side of the support assembly 10, and is used to place the bipolar plate and the membrane electrode. The design of the placement table 70 is to prevent the mixing of the membrane electrode and the bipolar plate during the disassembly and replacement process. The disassembled bipolar plates and membrane electrodes need to be placed on the placement table in order. During the replacement process, the membrane electrode and the bipolar plates need to be stacked on the fuel cell stack in the original order, providing an orderly placement space for the bipolar plates and the membrane electrode, helping to prevent material confusion and misoperation, and reducing the need for rework and inspection.

[0053] Preferably, the operation panel 60 is the core control center of the equipment, which integrates comprehensive control and monitoring functions, is intuitively designed and easy to operate. The operator can clearly monitor various operating parameters of the equipment through the operation panel 60, including key indicators such as pressing force and airtightness test results, and control and adjust the equipment in real time to ensure the efficiency and accuracy of the production process.

[0054] In addition, an advanced alarm system is integrated into the operation panel 60. At any stage of the equipment operation, such as during the press-fitting operation or the airtightness test, once it is detected that the press-fitting force of the battery stack does not meet the preset standard or the airtightness test result is lower than the qualified threshold, the operation panel 60 will immediately activate the alarm function, alert the operator through obvious sound and light signals, and automatically stop further operation of the equipment to prevent the continued production of unqualified products and avoid damage to the equipment or personnel due to operating errors.

[0055] Specifically, a plurality of rollers are provided at the bottom of the support assembly 10, and the rework press equipment can be moved by the rollers.

[0056] Preferably, a grating-type safety sensor is also provided in the protective component 50. When the equipment is being pressed and tested for air tightness, if a person accidentally touches the battery stack or enters the monitoring area of ​​the protective component 50, the grating-type safety sensor responds immediately and sends an interrupt signal to the control panel. At this time, after the program on the control panel receives this signal, it executes the emergency stop mechanism and suspends the program, effectively preventing injury to the operator and potential damage to the battery stack.

[0057] The working process of the repair and pressing equipment of the present invention is as follows:

[0058] For fuel cell stacks that only need to be stacked and assembled, the detection assembly 30 and the limit assembly 40 need to be moved to the rework area 120 via the slide rail assembly 130, and the stack is manually stacked in the limit space 410 of the limit assembly 40 in the rework area 120. After the stacking is completed, the detection assembly 30, the limit assembly 40 and the stack are moved into the press-fitting inspection area 110 via the slide rail assembly 130, so as to be press-fitted and tested for air tightness via the press-fitting assembly 20 and the detection assembly 30. For fuel cell stacks with qualified air tightness, the limit space 410 needs to be opened and the entire stack needs to be tightened and fixed manually using a manual tightening gun. The fixed fuel cell stack is moved from the press-fitting inspection area 110 to the rework area 120 via the slide rail assembly 130 for offline.

[0059] For the fuel cell stack that needs to be disassembled and replaced with bipolar plates and membrane electrodes, after the stack is placed in the limit space 410 of the limit assembly 40 that reaches the rework area 120, first, it needs to be moved into the press-fit detection area 110 for pressure relief operation, and then the program is set on the operation panel 60. At this time, the driving component 240 applies a force to the fuel cell stack. After this force is applied, the fuel cell stack is relieved of pressure by the driving component 240. At this time, the long screw installed on the stack is manually removed, and then the fuel cell stack is returned from the press-fit detection area 110 to the rework area 120; secondly, after returning to the rework area 120, the stack is manually disassembled and replaced. During the disassembly process, the bipolar plates and membrane electrodes are placed on the display table 70 in order. Finally, the fuel cell stack with disassembled and replaced bipolar plates and membrane electrodes is moved from the rework area 120 to the press-fit inspection area 110 again. The driving component 240 presses the stack according to the program set by the operation panel 60. After the press-fitting is completed, the air tightness of the stack is tested according to the set program. The fuel cell stack with qualified air tightness is tightened and fixed by manually using a manual tightening gun. The fixed fuel cell stack is braked from the press-fit inspection area 110 to the rework area 120 via the slide rail assembly 130 to be taken offline.

[0060] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0061] The repair and pressing equipment of the present invention includes: a support component 10, which is arranged on a support base surface, and a pressing detection area 110 is arranged above the support component 10; a pressing component 20, which is arranged on the support component 10 and is at least partially located above the pressing detection area 110, so as to press or depress the battery stack located in the pressing detection area 110; and a detection component 30, which is arranged on the support component 10 and is at least partially located in the pressing detection area 110, so as to detect the battery stack after pressing.
