Description

Technical Field

[0001] This utility model relates to the field of MEA bonding technology, and more specifically, to an MEA bonding device. Background Technology

[0002] In the field of battery technology, the membrane electrode assembly (MEA) is the core component of fuel cells, and its importance is self-evident. The MEA is a key site for multiphase material transport and electrochemical reactions in energy conversion, involving complex three-phase interface reactions and mass and heat transfer processes. Its performance directly determines the overall performance of the fuel cell, including efficiency, power density, lifespan, and ultimately, production cost. Therefore, the MEA manufacturing process, especially the bonding process, is crucial to the quality and performance of fuel cells. However, existing MEA bonding devices still have significant technical bottlenecks and operational difficulties in several aspects, which seriously restrict the efficiency and quality of fuel cell production.

[0003] First, in the material loading stage, the existing operating procedures are often too complicated and cumbersome. Operators need to manually perform multiple steps, which is not only time-consuming and labor-intensive, but also prone to human error. The complicated material loading process not only reduces production efficiency, but also increases the risk of operational errors, which may lead to material waste or unstable product quality. In addition, frequent manual operation also increases the possibility of the production environment being contaminated, which is a serious hidden danger for MEA production that requires high cleanliness.

[0004] Secondly, some existing MEA bonding devices use suction adsorption for material loading. While this method achieves automation to some extent, it has significant technical limitations. The most prominent problem is the lack of flexibility in controlling the suction speed. A fixed suction speed cannot adapt to different types or sizes of MEA materials, nor can it be adjusted in a timely manner according to changes in environmental conditions (such as temperature and humidity). This rigid suction system may result in excessive or insufficient adsorption force, thereby affecting the integrity of the material or the positioning accuracy. For precision thin film materials such as proton exchange membranes, improper adsorption force may cause membrane deformation or damage, directly affecting the performance and lifespan of the MEA.

[0005] Furthermore, although some equipment manufacturers have recognized the importance of air extraction speed control and have attempted to introduce some control mechanisms, these solutions are often crude and imperfect. The structures of these control devices are usually quite simple, lacking fine-tuning capabilities and stability. In actual production, due to factors such as equipment vibration, temperature changes, or wear and tear of components caused by long-term operation, these simple control mechanisms are prone to failure or deviation. This means that even if the operator sets a suitable air extraction speed, it may change due to various factors during production, resulting in the actual adsorption effect not matching expectations. This instability not only affects the consistency and reliability of production but may also increase the frequency and cost of equipment maintenance. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides an MEA bonding device, which has the following advantages:

[0019] 1. The bonding device innovatively solves the problem of cumbersome material feeding operations in existing technologies. By designing a combination of fixed and movable platforms, along with the flexible layout of components such as rotating and movable frames, a high degree of automation in the MEA bonding process is achieved. The suction holes on the fixed and movable platforms cleverly utilize pneumatic principles, greatly simplifying the material feeding process. This design not only improves operational efficiency but also significantly reduces the possibility of human error. The introduction of the rotating frame allows the entire bonding process to be carried out continuously, further improving production efficiency. The design of the movable frame increases the flexibility of the device. This bonding device design not only solves the limitations of traditional material feeding methods but also improves the consistency of product quality.

[0020] 2. The innovative design of the adjustment device effectively solves the problem of inflexible air extraction speed control in existing technologies. By introducing components such as a rotating sleeve, fixed tube, flow tube, and sealing rod, a precise airflow adjustment system is formed. This design allows the operator to precisely control the air extraction speed through simple rotation. Multiple flow holes on the flow tube, combined with the movement of the sealing rod, provide the possibility of multi-level adjustment, allowing the air extraction speed to be finely adjusted according to the needs of different MEA materials. This adjustment mechanism not only improves the flexibility and adaptability of the air extraction system, but also greatly reduces the risk of MEA material damage due to improper adsorption force, thereby improving the reliability of the production process and product quality.

[0021] 3. The positioning mechanism cleverly solves the problem of fluctuating air extraction speed in existing technologies. By introducing a combination of positioning sleeve, positioning rod, positioning groove, and return spring, a stable and reliable locking system is formed. The cooperation between the positioning rod and positioning groove and other components can accurately lock the position of the rotating sleeve after adjustment. The design of the return spring ensures that the positioning rod can automatically return to its original position, increasing the convenience and reliability of operation. This multi-locking mechanism not only ensures the stability of the air extraction speed after adjustment, but also effectively prevents accidental adjustments caused by vibration or other external factors during equipment operation. This positioning mechanism design significantly improves the stability and reliability of the entire bonding device, ensuring the consistency of air extraction speed during MEA production, thereby guaranteeing the stability of product quality.

[0032] Please see Figures 1-6An MEA bonding device includes a base 1, characterized in that: a bonding device is provided on the base 1, the bonding device including a fixed platform 2, a movable platform 3, an adsorption hole 4, a rotating frame 5, and a movable frame 6. The fixed platform 2 is detachably mounted on the rotating frame 5, the movable platform 3 is located above the fixed platform 2, the rotating frame 5 is located above the base 1, the adsorption holes 4 are respectively opened above the fixed platform 2 and the movable platform 3, and an adjustment device is connected to one side of both the fixed platform 2 and the movable platform 3. The adjustment device includes a rotating sleeve 7, a fixed tube 8, a flow tube 9, a flow hole 10, a sealing rod 11, a rigid tube 12, an adapter 13, and an adapter rod 14. The two ends of the rotating sleeve 7 are rotatably connected to the fixed tube 8 and the rigid tube 12 respectively. The fixed tube 8 is respectively connected to one side of the fixed platform 2 and the movable platform 3, and is fixed... The tube 8 is connected to the adsorption holes 4 opened on the inner side of the fixed platform 2 and the movable platform 3 respectively. The flow tube 9 is fixedly installed inside the fixed tube 8. Multiple flow holes 10 are opened on the outer side of the flow tube 9. The sealing rod 11 is movably installed in the flow tube 9. The adapter 13 is installed inside the rotating sleeve 7. The adapter rod 14 is connected to one end of the sealing rod 11, and the adapter rod 14 and the adapter 13 are slidably connected. A positioning mechanism is provided on the outer side of the fixed tube 8. The positioning mechanism includes a positioning sleeve 15, a positioning rod 16, a positioning groove 17 and a return spring 18. The positioning sleeve 15 is movably sleeved on the outer side of the fixed tube 8 by threads. One end of the positioning rod 16 is connected to the outer wall of the rotating sleeve 7 through the return spring 18. The other end of the positioning rod 16 is inserted into the positioning groove 17. Multiple positioning grooves 17 are opened on the outer side of the fixed tube 8.

[0033] The other end of the adapter rod 14 is connected to a mating rod 19, and a mating sleeve 20 is provided inside the rigid tube 12. The inner wall of the mating sleeve 20 and the outer wall of the mating rod 19 are connected by threads.

[0034] Both the rigid tube 12 and the rotating sleeve 7 are connected to the inner side of the connecting rod 21. The mating sleeve 20 is fixedly connected to the inner wall of the rigid tube 12 through the connecting rod 21, and the mating sleeve 13 is connected to the inner wall of the rotating sleeve 7 through the connecting rod 21.

[0035] In this embodiment, when the inhalation speed needs to be adjusted, firstly, rotate the positioning sleeve 15 so that it moves along the thread on the outer wall of the fixed tube 8. Then, the outer side of the positioning rod 16 will lose the limitation of the positioning sleeve 15. Then, hold the rigid tube 12 with one hand and rotate the rotating sleeve 7. The rotating sleeve 7 will drive the positioning rod 16 to move. Then, the side wall of the positioning groove 17 will squeeze the end of the positioning rod 16. Since the edge of the positioning groove 17 and the end of the positioning rod 16 are both designed with rounded corners, one end of the positioning rod 16 will slide out of the positioning groove 17, and the other end of the positioning rod 16 will pull the return spring 18 to stretch. At the same time, the rotating sleeve 7 will drive the adapter 13 to rotate through the connecting rod 21 connected to the inner wall. Due to the special structural design of the adapter rod 14 and the adapter 13, the adapter 13 will drive the adapter rod 14 to rotate. Then, the adapter rod 14 will drive the sealing rod 11 and the mating rod 19 connected at both ends to rotate. Since the mating rod 19 and the mating sleeve 20 are connected by threads, and the mating sleeve 20 is connected by threads... The connecting rod 21 and the rigid tube 12 are fixedly connected. Then, the mating rod 19 moves spirally along the threaded inner wall of the mating sleeve 20. The mating rod 19 drives the adapter rod 14 to slide along the adapter sleeve 13. The adapter rod 14 then drives the blocking rod 11 to slide in the flow tube 9. The number of flow holes 10 on the side wall of the flow tube 9 that are blocked will change, thus changing the volume of gas passing through and thus changing the pumping speed. After the change is appropriate, the rotation of the rotating sleeve 7 is stopped, so that the return spring 18 drives one end of the positioning rod 16 to engage in the corresponding positioning groove 17. Then, the positioning sleeve 15 is rotated in the opposite direction, so that the positioning sleeve 15 resets along the threaded outer side of the fixed tube 8. Then, the inner wall of the positioning sleeve 15 limits the outer end of the positioning rod 16 again, so that the positioning rod 16 will not move. Then, the positioning rod 16 and the positioning groove 17 cooperate to limit the rotation of the rotating sleeve 7, so that the rotating sleeve 7 will not rotate, thus ensuring the stability of the structure and ensuring that the adjusted pumping speed will not change.

[0036] Please see Figures 1-3 As a further implementation of the overall equipment: a fixed frame 22 is provided on the outer side of the base 1, and a movable frame 6 is rotatably mounted on the fixed frame 22. A cylinder 23 is detachably provided at the top of the movable frame 6, and a piston rod 24 is connected to the output end of the cylinder 23. The bottom end of the piston rod 24 is connected to the top of the movable platform 3.

[0037] A central sleeve 25 is connected below the rotating frame 5, and a mounting frame 26 is connected below the central sleeve 25. An air pump 27 is detachably installed on the inner side of the mounting frame 26 and above the movable platform 3.

[0038] The output end of the air pump 27 located above the movable platform 3 is connected to a connecting pipe 28. Here, the output end of the air pump 27 is connected to the rigid pipe 12 located on one side of the movable platform 3 through the connecting pipe 28. The output end of the air pump 27 located inside the mounting bracket 26 is connected to a delivery pipe 29. The delivery pipe 29 connected to the output end of the air pump 27 passes through the central sleeve 25 and is connected to the rigid pipe 12 located on one side of the fixed platform 2.

[0039] Both the central sleeve 25 and the movable frame 6 are fitted with driven wheels 30 on the outer side of their bottom ends. A driving wheel 31 is provided on one side of the driven wheel 30. The driving wheel 31 meshes with the driven wheel 30. A motor 32 can be detachably installed on both the fixed frame 22 and the base 1.

[0040] Both the base 1 and the fixed frame 22 are detachably equipped with a reducer 33. The input end of the reducer 33 is connected to the output end of the motor 32, and the output end of the reducer 33 is connected to the drive wheel 31.

[0041] More specifically, when the equipment is needed, the GDL is first transported via a conveyor located on one side of one of the fixed frames 22. Then, the motor 32 installed above the fixed frame 22 is turned on. After being reduced in speed by the reducer 33, the motor 32 drives the drive wheel 31 to rotate. The drive wheel 31 then drives the driven wheel 30, which in turn rotates, thereby rotating the movable frame 6. When the movable platform 3 located below the movable frame 6 moves directly above the transported GDL, the motor 32 is turned off. Then, the cylinder 23 installed at the top of the movable frame 6 is turned on, causing the piston rod 24 connected to the output end of the cylinder 23 to lower the movable platform 3. When the lower end of the movable platform 3 is in contact with the GDL, the movable platform 3 is opened. The air pump 27 installed on the platform evacuates air through the connecting pipe 28, causing the movable platform 3 to suck up the GDL through the suction hole 4. Then, the above steps are reversed to reset the movable platform 3. Then, the cylinder 23 is opened again, causing the piston rod 24 connected to the output end of the cylinder 23 to drive the movable platform 3 and the sucked GDL to descend. When the GDL descends above the fixed platform 2, the air pump 27 above the movable platform 3 is turned off, so that the movable platform 3 no longer sucks up the GDL. Then, the air pump 27 in the mounting bracket 26 corresponding to the fixed platform 2 is turned on, causing the air pump 27 to evacuate air through the delivery pipe 29, so that the suction hole 4 opened above the fixed platform 2 sucks up the GDL. Then, the movable platform 3 is operated to advance... Reset the machine, then turn on the motor 32 mounted on the base 1. After being reduced in speed by the reducer 33, the motor 32 drives the drive wheel 31 to rotate. The drive wheel 31 then drives the driven wheel 30 mounted on the outer side of the through sleeve 25 to rotate. The through sleeve 25 then drives the mounting bracket 26 and the rotating bracket 5 to rotate. This causes the air pump 27 mounted on the inner side of the mounting bracket 26 and the fixed platform 2 mounted on the top of the rotating bracket 5 to rotate with the through sleeve 25. When rotating to the next station, briefly stop the motor 32 here, and then perform a dispensing operation above the GDL using an external dispensing device. Then turn on the motor 32 again, causing the fixed platform 2 to move the GDL to another station. Then repeat the above steps to pass the MEA through this station. An external conveyor transports the MEA, causing the movable platform 3 corresponding to this workstation to attract and reset the MEA, aligning it with the GDL. Then, the cylinder 23 above the movable frame 6 is activated, and the piston rod 24 connected to the output end of the cylinder 23 lowers the movable platform 3 and the attracted MEA, allowing the MEA and GDL to adhere. After adhesion, the movable platform 3 resets, and the motor 32 mounted on the base 1 is activated again, causing the rotating frame 5 to move the adhered GDL and MEA one workstation. An external baking device then dries the adhesive, and the motor 32 on the base 1 again moves the rotating frame 5 one workstation.Then, the GDL and MEA to be bonded are adsorbed by the movable table 3 and other components corresponding to this workstation. Simultaneously, the corresponding air pump 27 installed inside the mounting bracket 26 is turned off, so that the fixed table 2 no longer adsorbs the GDL and MEA. Then, through the cooperation of the movable table 3 and other corresponding components, the bonded GDL and MEA are placed on an external reverse conveyor, which then transports them to the next process.

[0042] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the suction speed, first rotate the positioning sleeve 15, causing it to move along the thread on the outer wall of the fixed tube 8. Then, the outer side of the positioning rod 16 will lose the limitation of the positioning sleeve 15. Then, hold the rigid tube 12 with one hand and rotate the rotating sleeve 7. The rotating sleeve 7 will drive the positioning rod 16 to move. Then, the side wall of the positioning groove 17 will squeeze the end of the positioning rod 16. Since the edge of the positioning groove 17 and the end of the positioning rod 16 are both designed with rounded corners, one end of the positioning rod 16 will slide out of the positioning groove 17, and the other end of the positioning rod 16 will pull the return spring 18 for stretching. At the same time, the rotating sleeve 7 will drive the adapter 13 to rotate through the connecting rod 21 connected to the inner wall. Due to the special structural design of the adapter rod 14 and the adapter 13, the adapter 13 will drive the adapter rod 14 to rotate. Then, the adapter rod 14 will drive the sealing rod 11 and the mating rod 19 connected at both ends to rotate. Since the mating rod 19 and the mating sleeve 20 are connected by threads, and the mating sleeve 20 is fixedly connected to the rigid tube 12 via connecting rod 21. Then, the mating rod 19 moves spirally along the threaded inner wall of the mating sleeve 20. The mating rod 19 drives the adapter rod 14 to slide along the adapter sleeve 13. The adapter rod 14 then drives the blocking rod 11 to slide in the flow tube 9. The number of flow holes 10 on the side wall of the flow tube 9 that are blocked will change, thus changing the volume of gas passing through and thereby changing the pumping speed. After the change is appropriate, the rotation of the rotating sleeve 7 is stopped, so that the return spring 18 drives one end of the positioning rod 16 to engage in the corresponding positioning groove 17. Then, the positioning sleeve 15 is rotated in the opposite direction, so that the positioning sleeve 15 resets along the threaded outer side of the fixed tube 8. Then, the inner wall of the positioning sleeve 15 limits the outer end of the positioning rod 16 again, so that the positioning rod 16 will not move. Then, the positioning rod 16 and the positioning groove 17 cooperate to limit the rotation of the rotating sleeve 7, so that the rotating sleeve 7 will not rotate, thus ensuring the stability of the structure and ensuring that the adjusted pumping speed does not change.

[0043] When the equipment is needed, the GDL is first transported via a conveyor located on one side of one of the fixed frames 22. Then, the motor 32 installed above the fixed frame 22 is turned on. After being reduced in speed by the reducer 33, the motor 32 drives the drive wheel 31 to rotate. The drive wheel 31 then drives the driven wheel 30, which in turn rotates, thereby rotating the movable frame 6. When the movable platform 3 located below the movable frame 6 moves directly above the transported GDL, the motor 32 is turned off. Then, the cylinder 23 installed at the top of the movable frame 6 is turned on, causing the cylinder 23 to lower the movable platform 3 via the piston rod 24 connected to its output end. When the lower surface of the movable platform 3 is in contact with the GDL, the valve installed on the movable platform 3 is turned on. Air pump 27 draws air through connecting pipe 28, causing movable platform 3 to suck up GDL through suction hole 4. Then, the above steps are reversed to reset movable platform 3. Then, cylinder 23 is opened again, causing piston rod 24 connected to the output end of cylinder 23 to drive movable platform 3 and the sucked GDL to descend. When GDL descends above fixed platform 2, air pump 27 above movable platform 3 is turned off, so that movable platform 3 no longer sucks up GDL. Then, air pump 27 in mounting bracket 26 corresponding to fixed platform 2 is opened, causing air pump 27 to draw air through delivery pipe 29, causing suction hole 4 above fixed platform 2 to suck up GDL. Then, movable platform 3 is operated to reset. Then, turn on the motor 32 installed on the base 1, so that after the reduction action of the reducer 33, the motor 32 drives the drive wheel 31 to rotate. Then, the drive wheel 31 drives the driven wheel 30 sleeved on the outside of the through sleeve 25 to rotate. Then, the through sleeve 25 drives the mounting frame 26 and the rotating frame 5 to rotate, so that the air pump 27 installed on the inside of the mounting frame 26 and the fixed platform 2 installed on the top of the rotating frame 5 follow the rotation of the through sleeve 25. When rotating to the next station, briefly stop the motor 32 here, and then perform a dispensing operation above the GDL using an external dispensing device. Then turn on the motor 32 again, so that the fixed platform 2 drives the GDL to move to another station. Then, repeat the above steps to pass the MEA through the side of this station. An external conveyor transports the MEA, causing the movable platform 3 corresponding to this workstation to attract and reset the MEA, aligning it with the GDL. Then, the cylinder 23 above the movable frame 6 is activated, and the piston rod 24 connected to the output end of the cylinder 23 lowers the movable platform 3 and the attracted MEA, allowing the MEA and GDL to adhere. After adhesion, the movable platform 3 resets, and the motor 32 mounted on the base 1 is activated again, causing the rotating frame 5 to move the adhered GDL and MEA one workstation. An external baking device then dries the adhesive, and the motor 32 on the base 1 moves the rotating frame 5 one workstation again.Then, the GDL and MEA to be bonded are adsorbed by the movable table 3 and other components corresponding to this workstation. Simultaneously, the corresponding air pump 27 installed inside the mounting bracket 26 is turned off, so that the fixed table 2 no longer adsorbs the GDL and MEA. Then, through the cooperation of the movable table 3 and other corresponding components, the bonded GDL and MEA are placed on an external reverse conveyor, which then transports them to the next process.
