Description

Technical Field

[0001] This invention relates to the field of fuel cell manufacturing technology, and more specifically, to a MEA bonding and packaging production line. Background Technology

[0002] In the field of fuel cell manufacturing, the membrane electrode assembly (MEA) is one of the core components, and its performance directly affects the power generation efficiency, durability, and cost of the fuel cell. The MEA has a complex structure, encompassing a gas diffusion layer, a catalyst layer, and a proton exchange membrane. Precise and efficient bonding and encapsulation of these components is crucial to ensuring stable MEA performance. However, current MEA bonding and encapsulation production lines and methods have many shortcomings. In the bonding process, manual placement of the MEA modules is prone to misalignment, and it is difficult to automatically and accurately adjust the processing device based on the actual position of the material. Material placement deviations can easily lead to equipment malfunctions, severely impacting work efficiency, increasing labor costs, reducing production efficiency, and causing inconsistent product quality due to human factors. Regarding continuous production, continuous feeding is not possible, requiring batch operations, which is insufficient to meet the needs of large-scale industrial production. Summary of the Invention

The frame cutting and CCM cutting are carried out independently and in parallel. The traction suction plate pulls the frame to adjust its position on the second sliding suction plate and pulls the frame to the frame cutting head for positioning and cutting. After the frame is cut, it is automatically corrected and discharged to the frame discharge slide plate by the second discharge component. The transport device simultaneously removes the CCM and two frame pieces, and then moves the CCM and two frame pieces sequentially below the visual positioning device to obtain the position information of the CCM and the frame pieces; After the handling device identifies the location information, it moves the CCM and frame to the hot press device according to the location information.

[0021] like Figure 1 As shown, an embodiment of the present invention provides an MEA bonding and packaging production line, including a feeding mechanism, a bonding mechanism, and a conveying device 6. The feeding mechanism includes a CCM feeding and cutting device 1, a frame feeding and cutting device 2, and a vision positioning device 3. The CCM feeding and cutting device 1 is used to feed and cut CCM rolls, the frame feeding and cutting device 2 is used to feed and cut frame rolls, and the vision positioning device 3 is disposed between the CCM feeding and cutting device 1 and the frame feeding and cutting device 2 and is used to obtain the position information of the cut CCM or frame. The bonding mechanism includes a hot pressing device 4 and a cold pressing device 5. The hot pressing device 4 is used to hot-press and bond the CCM and the frame to form an MEA, and the cold pressing device 5 is used to cold-press and shape the MEA. The conveying device 6 is used to transfer the CCM or frame to the hot pressing device 4 according to the position information.

[0022] The aforementioned MEA bonding and packaging production line achieves continuous feeding and automatic cutting of roll materials through CCM feeding and cutting device 1 and frame feeding and cutting device 2, reducing manual intervention and improving production cycle time. The conveying device 6, combined with the vision positioning device 3, enables precise gripping and transfer of CCM and frame, avoiding the inefficiency caused by manual operation and significantly improving the automation level of the production line. The vision positioning device 3 obtains the position information of the cut CCM and frame in real time, ensuring accurate alignment of subsequent bonding processes, reducing defects such as misalignment and wrinkles, and improving the yield of MEA. The hot pressing device 4 and cold pressing device 5 complete the bonding and shaping of CCM and frame in steps, avoiding material deformation or stress residue caused by traditional single hot pressing, and ensuring the dimensional stability and electrochemical performance consistency of MEA.

[0023] like Figure 2As shown, in one embodiment, the feeding mechanism further includes a first processing table 7, a second processing table 8, and a connecting table 9. The first processing table 7 is provided with a CCM cutting waste frame 71, and the second processing table 8 is provided with a border cutting waste frame. The CCM feeding and cutting device 1 includes a CCM unwinding structure and a CCM cutting structure installed on the first processing table 7. The border feeding and cutting device 2 includes a border unwinding structure and a border cutting structure installed on the second processing table 8. The connecting table 9 connects the first processing table 7 and the second processing table 8, and the visual positioning device 3 is installed on the connecting table 9. By setting a CCM cutting waste box 71 on the first processing table 7 and a frame cutting waste box on the second processing table 8, the automatic collection and classification of cutting waste is achieved, avoiding waste accumulation that affects the production environment, and facilitating recycling and reducing material loss. The modular design of the first processing table 7, the second processing table 8 and the connecting table 9 allows the feeding and cutting processes of CCM and frame to be carried out in separate areas, avoiding mutual interference. At the same time, the connecting table 9 enables the two parts to work together, improving the compactness and rationality of the production line layout. Furthermore, the vision positioning device 3 is installed on the connecting table 9, which can simultaneously cover the positioning requirements after the cutting of CCM and frame, reducing repeated inspection steps and improving inspection efficiency.

[0024] In one embodiment, the CCM unwinding structure includes a CCM unwinding roller group and a CCM film take-up roller group. The CCM unwinding roller group is used for winding the CCM roll material, and the CCM film take-up roller group is used for winding the CCM protective film. The frame unwinding structure includes a frame unwinding roller group and a frame film take-up roller group. The frame unwinding roller group is used for winding the frame roll material, and the frame film take-up roller group is used for winding the frame protective film. The coordinated design of the CCM unwinding roller group and the CCM film take-up roller group allows for the simultaneous unwinding of the CCM roll material and recovery of the protective film, achieving a continuous supply of CCM material and significantly improving production efficiency. Similarly, the combined use of the frame unwinding roller group and the frame film take-up roller group enables the unwinding of the frame material and the recovery of the protective film, ensuring continuous and uninterrupted operation of the production line. The independent protective film take-up ensures that the protective film of the CCM and the frame is peeled off smoothly and evenly, avoiding material stretching deformation or contamination that may occur with traditional manual film tearing, and guaranteeing the material quality of subsequent cutting and laminating processes.

[0025] like Figure 2 and Figure 4As shown, in one embodiment, the CCM cutting structure includes a first sliding suction plate 11, a CCM cutting component 12, a first discharge component 13, and a retraction component 14. The first sliding suction plate 11 is used to absorb and place the CCM roll. The first sliding suction plate 11, the CCM cutting component 12, and the first discharge component 13 are all slidably mounted on the first processing table 7. The retraction component 14 is fixedly mounted on the first processing table 7. A CCM cutting head 121 is slidably provided on the CCM cutting component 12. The CCM cutting head 121 is provided with a first cutting blade and a first vision camera for acquiring CCM correction angle information. A first correction component 131 that can be raised and lowered relative to the first sliding suction plate 11 is slidably provided on the first discharge component 13. The first correction component 131 is used to identify the CCM correction angle information and to correct the CCM after cutting. A first correction suction plate 132 for absorbing CCM is rotatably mounted on the first correction component 131. Thus, by providing a first sliding suction plate 11, the reciprocating sliding of the first sliding suction plate 11 can pull and position the CCM roll material to the CCM cutting component 12 for cutting. At the same time, the first sliding suction plate 11 can accurately adsorb and position the CCM roll material, avoiding material displacement during the cutting process and ensuring cutting stability. By providing a first correction component 131, the first correction component 131, combined with the detection data of the first vision camera, automatically adjusts the position and angle of the CCM, eliminating the offset or twisting during material feeding, and ensuring that the cut CCM meets the positioning requirements of the subsequent bonding process. By providing a material ejection component 14, when the CCM protective film is peeled off the surface of the CCM roll material, the material ejection component 14 works in conjunction with the first sliding suction plate 11 to keep the CCM flat and fixed during the peeling process, preventing material displacement or deformation caused by the peeling operation.

[0026] Specifically, the CCM cutting assembly 12 is also equipped with a first dust removal component. This component removes debris and dust generated during cutting in real time, reducing the wear rate of the first cutting blade.

[0027] like Figure 4 and Figure 5As shown, in one embodiment, the unloading assembly 14 includes an abutment 141, an unloading suction plate 142, and a fixed frame 143 fixedly mounted on the first processing table 7. The abutment 141 is detachably mounted on the fixed frame 143 and is provided with a peeling piece 1411 for abutting the CCM protective film. The unloading suction plate 142 is slidably mounted on the fixed frame 143 and can be raised and lowered relative to the fixed frame 143. The unloading suction plate 142 is located above the first sliding suction plate 11. Thus, by providing an abutment member 141, which is detachable and can be replaced with peeling strips 1411 of different specifications, precise contact with the protective film is ensured. The mechanical contact between the peeling strip 1411 and the protective film, combined with vacuum adsorption, achieves gradual peeling of the protective film. At the same time, the peeling angle and force can be precisely controlled to ensure that the surface structure of the CCM functional layer is not damaged. By providing a material ejection suction plate 142, the material ejection suction plate 142 adjusts the adsorption force on the protective film in real time during the lifting process, offsetting the tensile stress generated by the peeling of the protective film and preventing the CCM from bending and deforming after the protective film is peeled off.

[0028] like Figure 2 and Figure 3 As shown, in one embodiment, the frame cutting structure includes a second sliding suction plate 21, a frame traction cutting component 22, and a second discharge component 23, all slidably mounted on a second processing table 8. The second sliding suction plate 21 is used to adsorb and place the frame roll material. The frame traction cutting component 22 includes a slidably disposed frame cutting head 222 and a traction suction plate 221 that can be raised and lowered relative to the second sliding suction plate 21. The frame cutting head 222 is provided with a second cutting blade and a second vision camera for acquiring frame correction angle information. The second discharge component 23 is slidably provided with a second correction component 231 that can be raised and lowered relative to the second sliding suction plate 21. The second correction component 231 is used to identify the frame correction angle information and to correct the frame after cutting. The second correction component 231 is rotatably mounted with a second correction suction plate 232 for adsorbing the frame. Thus, by providing the second sliding suction plate 21, the frame roll material can be accurately adsorbed and positioned, avoiding material displacement during the cutting process and ensuring cutting stability; by providing the traction suction plate 221, the reciprocating sliding of the traction suction plate 221 can pull and position the frame roll material onto the second sliding suction plate 21 for adsorption and fixation, facilitating subsequent cutting of the frame roll material using the second cutting blade; by providing the second correction component 231, the second correction component 231, combined with the detection data of the second vision camera, automatically adjusts the position and angle of the frame, eliminating offset or distortion during material feeding, ensuring that the cut frame meets the positioning requirements of the subsequent bonding process.

[0029] Specifically, the border traction cutting assembly 22 is also equipped with a second dust removal component. This component removes debris and dust generated during cutting in real time, reducing the wear rate of the second cutting blade.

[0030] Preferably, both the first and second dust removal components are hair dryers or air knives. The high-speed airflow generated by the hair dryer or air knife can quickly remove debris and dust generated during the cutting process, avoiding contamination of the CCM or frame surface and ensuring the cleanliness of the interface in subsequent bonding processes.

[0031] like Figure 2 As shown, in one embodiment, the visual positioning device 3 includes a third vision camera 31, a CCM (Chip CM) ejector slide 32, a frame ejector slide 33, and a support frame 34 mounted on the connecting table 9. The third vision camera 31 is mounted on the support frame 34 and is used to acquire the position information of the CCM or frame after cutting. A first guide rail is provided on the first processing table 7, extending to one end of the connecting table 9. A second guide rail is provided on the second processing table 8, extending to the other end of the connecting table 9. The CCM ejector slide 32 is slidably mounted on the first guide rail, and the frame ejector slide 33 is slidably mounted on the second guide rail. The third vision camera 31, fixed on the support frame 34, acquires the position information of the CCM or frame after cutting in real time, ensuring accurate identification and positioning of the material position, effectively reducing human intervention errors, improving processing accuracy, reducing defects such as misalignment and wrinkles, and improving the yield of MEA (Metal-on-Apart Materials).

[0032] Specifically, both the first and second guide rails are arranged horizontally. By extending the first and second guide rails to both ends of the connecting table 9, the CCM discharge slide plate 32 and the frame discharge slide plate 33 can move flexibly between different processing tables (first and second processing tables 8) and the connecting table 9, realizing independent conveying and coordinated positioning of the CCM and the frame, and optimizing the efficiency of the production process.

[0033] like Figure 1 and Figure 9 As shown, in one embodiment, the handling device 6 includes a mounting platform 61, a rotating base 62, a handling robot 63, and a handling fixture 64. The rotating base 62 is rotatably mounted on the mounting platform 61, the handling robot 63 is fixedly mounted on the rotating base 62, and the handling fixture 64 is detachably connected to the handling robot 63. The handling robot 63 has multiple handling suction plates 641 spaced circumferentially. By providing the rotating base 62, which is rotatably mounted on the mounting platform 61, the handling robot 63 can flexibly adjust its working direction to adapt to the material handling needs of different workstations, improving the adaptability of the production layout and the efficiency of operation. By providing the handling fixture 64, the detachable design of the handling fixture 64 supports rapid changeover, adapting to the handling needs of different specifications of CCM and frame, and multiple handling fixtures 64 can simultaneously handle the handling of CCM, frame, and MEA, effectively improving production efficiency.

[0034] Preferably, the handling robot 63 is a multi-axis manipulator. This is prior art, and its specific settings and installation methods will not be described in detail.

[0035] like Figure 1 and Figures 6-8 As shown, in one embodiment, the hot pressing device 4 includes a hot pressing table 41 and an upper suction plate 42 and a first lower suction plate 43 arranged vertically within the hot pressing table 41. The upper suction plate 42 can be raised and lowered relative to the hot pressing table 41, and a vacuum hot pressing space is formed between the upper suction plate 42 and the first lower suction plate 43. The cold pressing device 5 includes a cold pressing table 51, a feeding table 52, a lifting assembly 53, and a second lower suction plate 54. The cold pressing table 51 is connected to the feeding table 52, and the lifting assembly 53 is installed on the cold pressing table 51. Inside, the top of the lifting assembly 53 is provided with a lifting plate 531, which can be raised and lowered relative to the cold pressing table 51. The second lower suction plate 54 is fixed on the top of the lifting plate 531, and a cold pressing space is formed between the second lower suction plate 54 and the top of the cold pressing table 51. The unloading table 52 is provided with a finished product cassette 521 that can be raised and lowered relative to the unloading table 52. Multiple limiting strips 522 are protruding around the finished product cassette 521, and the multiple limiting strips 522 and the finished product cassette 521 cooperate to form a unloading space. The hot pressing space formed by the upper suction plate 42 and the first lower suction plate 43 can uniformly heat and pressurize the MEA, ensuring the stability and consistency of the hot pressing process and improving product quality. At the same time, the upper suction plate 42 can be raised and lowered relative to the hot pressing table 41, which facilitates the adjustment of the hot pressing gap and pressure and improves the flexibility of the process. The cold pressing table 51 cooperates with the unloading table 52 to enable the hot-pressed MEA to cool and solidify quickly in the cold pressing space, preventing deformation and ensuring the dimensional accuracy of the product. The finished product cassette 521 cooperates with the limiting strip 522 to form an unloading space, which can automatically collect and neatly stack finished products, reduce manual sorting time, and improve production efficiency.

[0036] like Figure 1 As shown, specifically, it also includes a vacuum assembly 44 connected to the hot pressing device 4. This creates a negative pressure environment for the hot pressing device 4, simultaneously applying temperature and pressure to achieve high-quality composite of the MEA. Vacuum hot pressing is existing technology and will not be described in detail here.

[0037] In another embodiment, there are two hot pressing devices 4, and the two hot pressing devices 4 are connected to each other. The two hot pressing devices 4 operate alternately to achieve continuous production.

[0038] like Figure 1 As shown, the MEA bonding and packaging production line further includes a power control cabinet 10, which is electrically connected to the feeding mechanism, bonding mechanism, and conveying device 6. This achieves efficient collaboration and intelligent control of the various modules on the MEA bonding and packaging production line.

[0039] The above embodiments form a complete "hot pressing-cold pressing-unloading" process by having the cold pressing device 5 and the hot pressing device 4 work together, thereby optimizing the production line layout and improving the overall level of automation.

[0040] A manufacturing method for an MEA bonding and packaging production line includes the following steps: S1. Feed the CCM roll material and the edge roll material onto the CCM feeding and cutting device 1 and the edge feeding and cutting device 2 respectively, and lay the CCM and the edge flat onto the first sliding suction plate 11 and the second sliding suction plate 21 for adsorption. S2. The first sliding suction plate 11 slides and pulls the CCM to the CCM cutting component 12 for positioning and cutting. Then, the cut CCM is automatically corrected and discharged to the CCM discharge slide plate 32 through the first discharge component 13. S3. The frame cutting and CCM cutting are carried out independently and in parallel. The traction suction plate 221 pulls the frame to adjust its position on the second sliding suction plate 21 and pulls the frame to the frame cutting head 222 for positioning and cutting. Then the cut frame is automatically corrected and discharged to the frame discharge slide plate 33 through the second discharge component 23. S4. The conveying device 6 simultaneously removes the CCM and the two frame pieces, and moves the CCM and the two frame pieces to below the visual positioning device 3 in sequence to obtain the position information of the CCM and the frame pieces. S5. After the handling device 6 identifies the position information, it moves the CCM and the frame to the hot pressing device 4 according to the position information. First, it places one frame on the first lower suction plate 43, then places another frame on the upper suction plate 42, and finally stacks the CCM on the top of the frame of the first lower suction plate 43 to complete the hot pressing and bonding to form MEA.
