Description

Technical Field

[0001] This application belongs to the field of proton exchange membrane electrolysis for hydrogen production technology, specifically relating to a membrane electrode sealing system. Background Technology

[0002] In the process of industrializing the new energy industry, especially in the process of proton exchange membrane electrolysis of water to produce hydrogen, the membrane electrode, as the core functional component of proton exchange membrane electrolysis of water to produce hydrogen, has its structural integrity and packaging reliability directly affecting the energy conversion efficiency, long-term service life and safety performance of proton exchange membrane electrolysis of water to produce hydrogen.

[0003] The sealing process of the membrane electrode assembly (MEA) is a core step in its manufacturing process. It requires sealing the edges of the proton exchange membrane with a frame material to prevent electrolyte leakage, avoid reactant gas cross-contamination, and ensure the structural stability of the MEA during subsequent assembly processes and long-term battery operation. Therefore, the effectiveness of the sealing process directly affects the product quality of the MEA and the overall performance of proton exchange membrane electrolysis for hydrogen production, significantly impacting the feasibility of large-scale mass production.

[0004] However, the mainstream membrane electrode sealing equipment in the industry still generally adopts a single-machine, single-piece non-continuous production mode. The operation process of this mode is based on a single membrane electrode, and the processes of raw material feeding, membrane positioning, edge and membrane bonding, and curing are completed in sequence. After each membrane electrode is sealed, the equipment stops to unload the finished product, and then the next raw material feeding and positioning operation is carried out again.

[0005] This production model results in significant pauses between processes, making it impossible to form a continuous and smooth production flow. This leads to a substantial reduction in the effective operating time of equipment and limited capacity output per unit time, making it difficult to match the growing demand for large-scale, high-efficiency mass production of membrane electrodes in the industrialization process of proton exchange membrane electrolysis for hydrogen production. Summary of the Invention

[0006] In view of this, this application provides a membrane electrode sealing system, the main purpose of which is to build a production flow without interruption and realize the continuous operation of the sealing process.

[0007] To achieve the above objectives, this application mainly provides the following technical solutions:

[0014] The timing of the third mobile lifting component conforms to the second preset timing: after the first mobile lifting component returns from the continuous bonding and curing area to the first raw material processing area, the third mobile lifting component carries the proton exchange membrane finished product and moves along the second path from the second raw material processing area to the continuous bonding and curing area to achieve coordinated action with the first mobile lifting component.

[0015] Optionally, the first mobile lifting assembly, the second mobile lifting assembly, and the third mobile lifting assembly are all equipped with a liftable adsorption platform. The adsorption platform is a negative pressure adsorption structure and is used to switch between a first height position and a second height position under the action of the lifting mechanism.

[0016] The first height position is higher than the second height position;

The second transport mechanism is located adjacent to the stopping position of the second movable lifting assembly in the continuous bonding and curing area. The flipping mechanism is located on the side of the conveying mechanism away from the curing mechanism along the conveying direction of the conveying mechanism.

[0023] Optionally, the flipping mechanism includes a horizontal module, a vertical module, a flipping motor, a flipping spindle, and a flipping platform;

[0024] The horizontal module is arranged parallel to the conveying direction of the conveying mechanism, and the vertical module is vertically installed on the sliding end of the horizontal module. The vertical module can reciprocate along the conveying direction under the drive of the horizontal module. The flipping motor is fixed to the lifting end of the vertical module and can move up and down in the vertical direction under the drive of the vertical module. One end of the flipping main shaft is coaxially and fixedly connected to the output shaft of the flipping motor, and one side of the flipping platform is fixedly connected to the other end of the flipping main shaft, so that the flipping platform can rotate around the axis of the flipping main shaft under the drive of the flipping motor to achieve a flipping action of 0°-180°.

[0025] The flipping platform is also a negative pressure adsorption structure, which is used to fix the finished frame film product by negative pressure adsorption when the second conveying mechanism places the finished frame film product on the flipping platform.

[0026] Optionally, both the first and second transport mechanisms have at least five degrees of freedom, and both the first and second transport mechanisms are equipped with a gripping platform and a visual monitoring module at their ends. The gripping platform is also a negative pressure adsorption structure.

[0027] Optionally, both the first cutting mechanism and the second cutting mechanism have at least five degrees of freedom, and both the first cutting mechanism and the second cutting mechanism are equipped with a galvanometer processing module at their ends.

[0028] Optionally, the membrane electrode sealing system further includes a charging area;

[0029] At least some of the path markers also lead to the charging area, which has at least three battery swapping stations.

[0030] Optionally, the feed end of the curing mechanism is connected to the discharge end of the conveying mechanism, and the curing mechanism includes an active heating roller, a driven pressure roller, a temperature control module, and a pressure regulating module arranged opposite each other in the vertical direction;

[0031] The active heating roller has an internal electric heating element on its roller surface, and the temperature control module is electrically connected to the electric heating element to regulate the roller surface temperature of the active heating roller to a preset curing temperature.

[0032] The pressure regulating module is connected to the driven pressure roller and is used to drive the driven pressure roller to move closer to or away from the active heating roller in a vertical direction, so as to adjust the pressing pressure between the active heating roller and the driven pressure roller.

[0033] By employing the above technical solution, this application has at least the following beneficial effects:

[0034] The membrane electrode sealing system provided in this application, by setting a first raw material processing area and its configured first unwinding and tearing mechanism, first winding mechanism, and first cutting mechanism, can realize continuous feeding and processing of frame film raw materials. Simultaneously, a first moving lifting component and a second moving lifting component, respectively arranged on at least two parallel first paths between the first raw material processing area and the continuous bonding and curing area, move back and forth along their respective first paths according to a first preset timing sequence, sequentially transferring the continuously processed frame film products from the first raw material processing area to the continuous bonding and curing area, with the two components stopping at different positions in the continuous bonding and curing area. The second raw material processing area and its configured second unwinding and tearing mechanism, second winding mechanism, and second cutting mechanism can realize… The current continuous feeding and processing of proton exchange membrane raw materials involves a third movable lifting component positioned on a second path between the second raw material processing zone and the continuous bonding and curing zone. This component works in coordination with the first movable lifting component according to a second preset timing sequence, reciprocating along the second path to transfer the proton exchange membrane finished product continuously processed in the second raw material processing zone to the continuous bonding and curing zone. The component's stopping position in the continuous bonding and curing zone is the same as that of the first movable lifting component. The conveying mechanism configured in the continuous bonding and curing zone sequentially receives the frame membrane finished product from the first movable lifting component, the proton exchange membrane finished product from the third movable lifting component, and the frame membrane finished product from the second movable lifting component according to a third preset timing sequence. After forming a stacked structure, the membrane is conveyed to the curing mechanism for curing. It should be noted that, compared to the single-machine, single-piece, non-continuous production mode adopted by the mainstream membrane electrode sealing equipment in the current industry, this membrane electrode sealing system achieves continuous operation of feeding, processing, and transferring frame membrane raw materials and proton exchange membrane raw materials, as well as the formation and curing of the laminated structure, through the coordinated cooperation of various components. This eliminates the interruptions between processes, forms a continuous and smooth production flow, significantly increases the effective operating time of the equipment, and increases the output capacity per unit time. It can meet the large-scale and high-efficiency mass production requirements of membrane electrodes in the industrialization process of proton exchange membrane water electrolysis for hydrogen production. At the same time, it ensures the precise cooperation of various components during the membrane electrode sealing process, which helps to improve the structural integrity and encapsulation reliability of the membrane electrode, thereby ensuring the energy conversion efficiency, long-term operating life, and safety performance of proton exchange membrane water electrolysis for hydrogen production.

[0048] See also Figures 1 to 6 As shown, according to an embodiment of this application, a membrane electrode sealing system is provided, including a first raw material processing area 100, a second raw material processing area 200, and a continuous bonding and curing area 300. The first raw material processing area 100 is equipped with a first unwinding and tearing mechanism 4, a first winding mechanism 5, and a first cutting mechanism 6 for continuous feeding and processing of the frame film raw material. At least two parallel first paths are provided between the first raw material processing area 100 and the continuous bonding and curing area 300. A first movable lifting component and a second movable lifting component are movably provided on the at least two first paths, respectively. The first movable lifting component and the second movable lifting component are used to reciprocate along their respective first paths according to a first preset time sequence to sequentially transfer the frame film finished product continuously processed in the first raw material processing area 100 to the continuous bonding and curing area 300. The first movable lifting component and the second movable lifting component have different stopping positions in the continuous bonding and curing area 300. The second raw material processing area 200 is equipped with a second unwinding and tearing machine. The system comprises a second winding mechanism 8 and a second cutting mechanism 9, used for continuous feeding and processing of proton exchange membrane raw materials; at least one second path is provided between the second raw material processing area 200 and the continuous bonding and curing area 300, and a third movable lifting component is movably provided on the second path. The third movable lifting component and the first movable lifting component work together in accordance with a second preset timing sequence, moving back and forth along the second path to transfer the proton exchange membrane finished product continuously processed in the second raw material processing area 200 to the continuous bonding and curing area 300, and the stopping position of the third movable lifting component in the continuous bonding and curing area 300 is the same as the stopping position of the first movable lifting component; the continuous bonding and curing area 300 is equipped with a conveying mechanism 10 and a curing mechanism 11. The conveying mechanism 10 is used to sequentially receive the frame membrane finished product from the first movable lifting component, the proton exchange membrane finished product from the third movable lifting component, and the frame membrane finished product from the second movable lifting component in accordance with a third preset timing sequence to form a laminated structure and convey it to the curing mechanism 11.

[0049] The membrane electrode sealing system provided in the embodiments of this application, by setting a first raw material processing area 100 and its configured first unwinding and tearing mechanism 4, first winding mechanism 5, and first cutting mechanism 6, can realize continuous feeding and processing of frame film raw materials. At the same time, the first moving lifting component and the second moving lifting component, respectively set on at least two parallel first paths between the first raw material processing area 100 and the continuous bonding and curing area 300, move back and forth along their respective first paths according to a first preset time sequence, so that the frame film finished products continuously processed in the first raw material processing area 100 can be sequentially transferred to the continuous bonding and curing area 300, and the two stop at different positions in the continuous bonding and curing area 300; the second raw material processing area 200 and its configured second unwinding and tearing mechanism 7, second winding mechanism 8, and second cutting mechanism 6 can realize continuous feeding and processing of frame film raw materials. Mechanism 9 enables continuous feeding and processing of proton exchange membrane raw materials. A third movable lifting component, arranged on the second path between the second raw material processing area 200 and the continuous bonding and curing area 300, works in coordination with the first movable lifting component according to a second preset timing sequence, reciprocating along the second path. This allows the proton exchange membrane finished product continuously processed in the second raw material processing area 200 to be transferred to the continuous bonding and curing area 300, and its stopping position in the continuous bonding and curing area 300 is the same as that of the first movable lifting component. The conveying mechanism 10 configured in the continuous bonding and curing area 300 sequentially receives the frame membrane finished product from the first movable lifting component, the proton exchange membrane finished product from the third movable lifting component, and the frame membrane finished product from the second movable lifting component according to a third preset timing sequence. After forming a stacked structure, the membrane is conveyed to the curing mechanism 11 for curing. It should be noted that, compared to the single-machine, single-piece, non-continuous production mode adopted by the mainstream membrane electrode sealing equipment in the current industry, this membrane electrode sealing system achieves continuous operation of feeding, processing, and transferring frame membrane raw materials and proton exchange membrane raw materials, as well as the formation and curing of the laminated structure, through the coordinated cooperation of various components. This eliminates the interruptions between processes, forms a continuous and smooth production flow, significantly increases the effective operating time of the equipment, and increases the output capacity per unit time. It can meet the large-scale and high-efficiency mass production requirements of membrane electrodes in the industrialization process of proton exchange membrane water electrolysis for hydrogen production. At the same time, it ensures the precise cooperation of various components during the membrane electrode sealing process, which helps to improve the structural integrity and encapsulation reliability of the membrane electrode, thereby ensuring the energy conversion efficiency, long-term operating life, and safety performance of proton exchange membrane water electrolysis for hydrogen production.

[0050] The first raw material processing area 100 is responsible for preparing the frame film. Specifically, the first unwinding and tearing mechanism 4 unrolls the frame film raw material and tears off its protective film. Then, the first cutting mechanism 6 cuts the unrolled section of the frame film raw material to the required dimensions. Waste generated during this process is collected by the first winding mechanism 5. The finished frame film is then transported to the continuous bonding and curing area 300 via two parallel first paths by independent first and second moving lifting components. Since the first and second moving lifting components have the same receiving station in the first raw material processing area 100, to avoid collisions, they alternately reciprocate along their respective first paths according to a first preset timing sequence to receive the finished frame film, effectively preventing collisions. Here, the first preset timing sequence refers to the pre-set action time order and interval pattern of the first and second moving lifting components.

[0051] Specifically, when the initial positions of the first and second mobile lifting components are configured such that the first mobile lifting component is located in the first raw material processing area 100 and the second mobile lifting component is located in the continuous bonding and curing area 300, the linkage relationship between the first and second mobile lifting components conforms to the first preset timing sequence. The specific linkage process is as follows: when the first mobile lifting component carries the finished frame film along the corresponding first path from the first raw material processing area 100 to the continuous bonding and curing area 300, the second mobile lifting component will move along the corresponding first path from the continuous bonding and curing area 300 to the first raw material processing area 100 to receive the next batch of finished frame film; and when the first mobile lifting component returns from the continuous bonding and curing area 300 to the first raw material processing area 100 along the corresponding first path, the second mobile lifting component will carry the finished frame film along the corresponding first path from the first raw material processing area 100 to the continuous bonding and curing area 300. Here, to achieve orderly, efficient, and safe transfer operations, the first and second mobile lifting components stop at different positions in the continuous bonding and curing zone 300. This avoids positional conflicts when the first and second mobile lifting components hand over the finished frame membrane to the conveying mechanism 10, ensuring that the conveying mechanism 10 can sequentially receive the finished frame membrane from the first mobile lifting component, the finished proton exchange membrane from the third mobile lifting component, and the finished frame membrane from the second mobile lifting component according to the third preset timing sequence. This accurately completes the stacking of the three-layer membrane electrode structure and also reserves non-interfering operating space for the reciprocating movement of the first and second mobile lifting components, ensuring a continuous and smooth transfer process and further improving the system's operating efficiency.

[0052] Further, see Figure 2 As shown, two parallel first paths are provided between the first raw material processing area 100 and the continuous bonding and curing area 300. These two first paths are respectively set as path AB and path BD. The first moving lifting component responsible for transferring the finished frame film corresponds to path BD, while the second moving lifting component, which is also used for transferring the finished frame film, corresponds to path AB. Through this clear path correspondence, it is ensured that the first moving lifting component and the second moving lifting component can move along their respective dedicated paths during the transfer process, avoiding mutual interference.

[0053] The workflow of the second raw material processing area 200 is similar to that of the first raw material processing area 100, but it processes proton exchange membrane raw materials. Specifically, the second unwinding and tearing mechanism 7 unfolds the rolled proton exchange membrane raw materials and tears off the surface protective film. Then, the second cutting mechanism 9 cuts the unfolded section of the proton exchange membrane raw materials according to the required size. The waste generated in the process is recycled by the second winding mechanism 8. The proton exchange membrane finished product processed by these steps is transferred to the continuous bonding and curing area 300 by the third moving lifting component through the second path.

[0054] Specifically, in some examples, the second path is an independent path that does not interfere with the two first paths; in another example, at least a portion of the second path overlaps with at least a portion of the two first paths. In this embodiment, to simplify the path layout and structural design of the system, at least a portion of the second path overlaps with at least a portion of the first path corresponding to the first mobile lifting component. It should be noted that, to avoid collisions between the third mobile lifting component and the first mobile lifting component in the overlapping path portion and to ensure the orderly conduct of their transfer operations, the third mobile lifting component and the first mobile lifting component operate according to a second preset timing sequence. Furthermore, when the third mobile lifting component and the first mobile lifting component operate according to the second preset timing sequence, to further simplify the path layout and structural design of the system, the third mobile lifting component and the first mobile lifting component have the same stopping position in the continuous bonding and curing area 300. Here, the second preset timing sequence refers to the pre-set action time order and interval pattern of the third mobile lifting component and the first mobile lifting component.

[0055] Furthermore, when the initial positions of the third moving lifting component and the first moving lifting component are configured such that the third moving lifting component is located in the second raw material processing area 200 and the first moving lifting component is located in the first raw material processing area 100, the linkage relationship between the third moving lifting component and the first moving lifting component conforms to the second preset timing sequence. Specifically, the linkage process is as follows: after the first moving lifting component returns from the continuous bonding and curing area 300 to the first raw material processing area 100, the third moving lifting component, carrying the proton exchange membrane finished product, moves along the second path from the second raw material processing area 200 to the continuous bonding and curing area 300 to achieve coordinated action with the first moving lifting component. See here. Figure 2 As shown, the third moving support component of the proton exchange membrane finished product corresponds to path CD, and the overlapping part of path CD and path BD is path DE.

[0056] The continuous bonding and curing zone 300 is the area where the membrane electrode sealing is completed. Within this zone, the conveying mechanism 10 sequentially receives the frame membrane product transferred from the first moving support component, the proton exchange membrane product transferred from the third moving support component, and the frame membrane product transferred from the second moving support component, according to a third preset timing sequence. This gradually forms a stacked structure of frame membrane, proton exchange membrane, and frame membrane stacked sequentially. Subsequently, the conveying mechanism 10 transports this stacked structure to the curing mechanism 11, where the curing mechanism 11 completes the curing and sealing process between the frame membrane and the proton exchange membrane, ultimately forming a structurally complete and reliably sealed membrane electrode product. Here, the third preset timing sequence refers to the time order and interval pattern pre-set for the conveying mechanism 10 within the continuous bonding and curing zone 300 to sequentially receive the finished products transferred from different components.

[0057] Specifically, when the continuous bonding and curing area 300 is further equipped with a first transport mechanism 12, a second transport mechanism 13, and a flipping mechanism 14, and the first transport mechanism 12 is located adjacent to the stopping positions of the first and third moving lifting components in the continuous bonding and curing area 300, the second transport mechanism 13 is located adjacent to the stopping position of the second moving lifting component in the continuous bonding and curing area 300, and the flipping mechanism 14 is located on the side of the conveying mechanism 10 away from the curing mechanism 11 along the conveying direction of the conveying mechanism 10, the action sequence of the first transport mechanism 12, the second transport mechanism 13, and the flipping mechanism 14 conforms to a third preset sequence. The specific linkage process is as follows: the first transport mechanism 12 first moves the frame film onto the first moving lifting component. After the product is transferred to the continuous bonding and curing area 300, the frame film product is adsorbed and placed on the stacking station of the conveying mechanism 10. At the same time, after the third moving lifting component transfers the proton exchange membrane product to the continuous bonding and curing area 300, the proton exchange membrane product is adsorbed and stacked on the bonding surface of the frame film product at the stacking station. The second transport mechanism 13, after the second moving lifting component transfers the frame film product to the continuous bonding and curing area 300, adsorbs the frame film product and places it on the flipping mechanism 14. The flipping mechanism 14, after the proton exchange membrane product is stacked on the bonding surface of the frame film product at the stacking station, flips the frame film product it carries and presses the bonding surface of the frame film product onto the upper surface of the proton exchange membrane product.

[0058] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 3 As shown, the first, second, and third mobile lifting components are all equipped with a liftable adsorption platform 15. The adsorption platform 15 is a negative pressure adsorption structure. The adsorption platform 15 is used to switch between a first height position and a second height position under the action of the lifting mechanism 16. The first height position is higher than the second height position. When the adsorption platform 15 is at the first height position, the adsorption surface of the adsorption platform 15 can fit against the sealing surface of the frame membrane material or proton exchange membrane material and form a negative pressure adsorption, so that the frame membrane material or proton exchange membrane material forms a tension plane. When the adsorption platform 15 is at the second height position, the adsorption platform 15 can drive the cut frame membrane product or proton exchange membrane product to move.

[0059] In this embodiment, the first mobile lifting assembly, the second mobile lifting assembly, and the third mobile lifting assembly are all equipped with a liftable adsorption platform 15. The adsorption platform 15 adopts a negative pressure adsorption structure and can switch between a first height position and a second height position under the drive of the lifting mechanism 16, with the first height position being higher than the second height position. When the adsorption platform 15 is at the first height position, its adsorption surface can adhere to the sealing surface of the frame membrane material or proton exchange membrane material and form a negative pressure adsorption. With the help of the negative pressure, the originally rolled frame membrane material or proton exchange membrane material is unfolded to form a flat tension plane, which effectively avoids the curling phenomenon that occurs during the cutting process due to the curling characteristics of these two materials. When the adsorption platform 15 is at the second height position, it can smoothly drive the cut frame membrane product or proton exchange membrane product to move. Since the material has formed a tension plane through negative pressure adsorption before cutting, the cut product can also maintain good flatness and will not curl. In addition, when the subsequent conveying mechanism 10 performs the stacking operation, it ensures that the frame membrane product and the proton exchange membrane product can be accurately aligned, avoiding the problem of low membrane electrode yield caused by curling of the rolled frame membrane material or proton exchange membrane material during and after cutting, and misalignment during subsequent stacking, thus improving the yield of membrane electrode production.

[0060] In the membrane electrode sealing system of this application, the first mobile lifting assembly, the second mobile lifting assembly, and the third mobile lifting assembly responsible for transporting the finished edge membrane are consistent in their mobile structure configuration, and are all composed of a vehicle platform and Mecanum wheels.

[0061] Specifically, the vehicle platform is the basic load-bearing structure of the mobile lifting assembly, used to install the liftable adsorption platform 15, providing a stable mounting carrier for adsorbing and fixing raw materials or finished products. Mecanum wheels, as the mobile actuation components of the mobile lifting assembly, are installed at the four corners of the bottom of the vehicle platform, enabling flexible movement in multiple directions. This ensures that the mobile lifting assembly can quickly adjust to the target position during material receiving, transfer, and unloading, avoiding collisions with other components and guaranteeing the accuracy and smoothness of the entire system's transfer operations.

[0062] A lifting mechanism 16 is fixedly installed on the upper surface of the vehicle platform, facing upwards. The drive end of the lifting mechanism 16 is connected to the adsorption platform 15, which is used to drive the adsorption platform 15 to move in the vertical direction, thereby realizing the switching of the adsorption platform 15 between a first height position and a second height position, ensuring the smooth progress of subsequent processes such as raw material cutting and finished product transfer. Here, the lifting mechanism 16 can be a linear drive structure such as an electric push rod, cylinder, hydraulic cylinder, or ball screw transmission mechanism. The specific choice can be made according to the different requirements of the membrane electrode sealing system for lifting speed, load capacity, and control precision. This application does not limit this.

[0063] Specifically, a negative pressure generator, such as a vacuum pump, is fixedly installed on the upward-facing surface of the vehicle platform to provide negative pressure. The adsorption platform 15, used to adsorb the raw materials for the frame membrane or proton exchange membrane, has a hollow structure with an internal cavity. Multiple adsorption holes are evenly distributed on the upper surface of the adsorption platform 15. One end of each adsorption hole connects to the cavity inside the adsorption platform 15, while the other end is directly exposed on the adsorption surface. In practical applications, the negative pressure generator can establish a sealed connection with the cavity of the adsorption platform 15 through an air pipe or internal flow channel. When the negative pressure generator starts working, it continuously draws air from the cavity of the adsorption platform 15, creating a stable negative pressure environment within the cavity. At this time, the multiple adsorption holes on the adsorption surface transmit the negative pressure from the cavity to the contact point between the adsorption surface and the raw material or finished product, thereby generating a uniform adsorption force and forming a fully functional negative pressure adsorption structure. This enables stable and firm adsorption of the frame membrane raw material, proton exchange membrane raw material, and corresponding finished products after cutting, effectively avoiding problems such as raw material wrinkling or finished product displacement caused by uneven local force during the adsorption process.

[0064] The vehicle platform is equipped with a drive motor at its bottom, which is connected to a Mecanum wheel drive. By driving the Mecanum wheel, the vehicle platform can be moved to the receiving station in either the first raw material processing area 100 or the second raw material processing area 200. Here, the receiving station in the first raw material processing area 100 refers to the area located below the unfolded section of the frame film raw material and corresponding to the cutting position of the first cutting mechanism 6. Figure 2 Point B in the middle. The receiving station of the second raw material processing area 200 refers to the area located below the proton exchange membrane raw material unfolding section, corresponding to the cutting operation position of the second cutting mechanism 9, such as... Figure 2 Point C in the middle.

[0065] Specifically, in the material receiving stage of actual application, the drive motor first drives the Mecanum wheel to rotate, thereby driving the vehicle platform to move to the material receiving station in the raw material processing area. During this process, it is necessary to ensure that the adsorption platform 15 on the vehicle platform is precisely aligned with the finished product output position of the cutting mechanism in the raw material processing area. After alignment, the lifting mechanism 16 is activated, and its power output end drives the adsorption platform 15 to rise from the second height position to the first height position, so that the adsorption surface of the adsorption platform 15 is in close contact with the lower surface of the raw material. Immediately afterwards, the negative pressure generator is activated to extract the air from the cavity of the adsorption platform 15, so that the adsorption surface generates a uniform adsorption force, causing the raw material to form a flat tension plane. At this time, the raw material processing area... The cutting mechanism begins cutting the raw material under tension. After cutting, the adsorption force firmly fixes the finished product on the adsorption platform 15, effectively preventing the finished product from shifting during subsequent transportation. At the same time, the continuous negative pressure adsorption keeps the finished product on a flat tension plane, which can eliminate the curling stress caused by the raw material being stored in rolls, laying a solid foundation for the precise alignment of the subsequent lamination process. After the finished product's adsorption state is stable and meets the subsequent operating conditions, the lifting mechanism 16 is started again, driving the adsorption platform 15 from the first height position to the second height position, thereby removing the finished product and lowering the overall center of gravity of the moving lifting component, preparing for the movement of the vehicle platform in the subsequent transportation stage.

[0066] Furthermore, in the frame membrane material structure involved in this embodiment, the lower surface of the frame membrane material is a sealing surface that achieves the sealing function, and it is directly attached to the adsorption surface of the adsorption platform 15 to ensure subsequent adsorption stability; while the upper surface of the frame membrane material is a bonding surface used to bond with the proton exchange membrane finished product in the subsequent processing stage and play a docking role, providing a basis for material docking in subsequent processes.

[0067] In the above embodiments, see Figure 3 As shown, the first mobile lifting assembly, the second mobile lifting assembly, and the third mobile lifting assembly are all equipped with an image acquisition module 17. The image acquisition module 17 is used to identify path markers, and at least some of the path markers form paths that guide to the first raw material processing area 100, the second raw material processing area 200, and the continuous bonding and curing area 300.

[0068] Here, the image acquisition module 17 can provide real-time and accurate path guidance for each mobile lifting component by recognizing path markers. This ensures that the first and second mobile lifting components accurately travel back and forth between the first raw material processing area 100 and the continuous bonding and curing area 300 along their respective first paths, and also ensures that the third mobile lifting component accurately shuttles between the second raw material processing area 200 and the continuous bonding and curing area 300 along the second path, effectively avoiding the risk of collisions caused by path deviation. At the same time, this guidance also ensures that each mobile lifting component accurately arrives at the receiving and unloading stations, thereby providing a reliable guarantee for the smooth receiving and transfer of the finished edge membrane and proton exchange membrane, as well as the accurate alignment of the subsequent stacked structure. This further improves the stability and efficiency of the continuous operation of the entire membrane electrode sealing system and reduces production interruptions or product defects caused by path deviations.

[0069] The unloading station refers to the position within the continuous bonding and curing zone 300 where each moving lifting component is used to transfer finished products, specifically the positions corresponding to the first and third moving lifting components. Figure 2 Point D in the diagram, and the corresponding point of the second moving lifting component. Figure 2 Point A in the diagram.

[0070] The image acquisition module 17 can be a camera equipped with a color sensor and a vision sensor, as long as it can meet the function of recognizing path markers. This application does not limit its specific model or type. From the perspective of installation and functional adaptation, in actual application scenarios, the image acquisition module 17 needs to be fixedly installed on the vehicle platform of each mobile lifting component, and its monitoring end should be set facing the surface of the carrier where the path marker is located. The carrier can be the ground, etc.

[0071] The path markers can be color blocks, QR codes, barcodes, etc. Color blocks are colors that contrast sharply with the surface color of the carrier, used to distinguish paths through color differences. QR codes can embed path numbers, location coordinates, target workstations, etc., facilitating accurate acquisition of positioning data by the image acquisition module 17. Barcodes can form codes through combinations of stripes of different widths and spacings, used to determine the component's movement distance and direction in real time. It should be noted that the above path marker formats only need to be effectively adapted to the image acquisition module 17 and meet the system's path guidance and workstation positioning requirements; this application does not impose a unique limitation on their specific forms.

[0072] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 4As shown, the flipping mechanism 14 includes a horizontal module 18, a vertical module 19, a flipping motor 20, a flipping main shaft 21, and a flipping platform. The horizontal module 18 is arranged parallel to the conveying direction of the conveying mechanism 10. The vertical module 19 is vertically installed on the sliding end of the horizontal module 18, and the vertical module 19 can reciprocate along the conveying direction under the drive of the horizontal module 18. The flipping motor 20 is fixed to the lifting end of the vertical module 19, and the flipping motor 20 can be lifted and lowered in the vertical direction under the drive of the vertical module 19. One end of the flipping main shaft 21 is coaxially fixedly connected to the output shaft of the flipping motor 20, and one side of the flipping platform is fixedly connected to the other end of the flipping main shaft 21, so that the flipping platform can rotate around the axis of the flipping main shaft 21 under the drive of the flipping motor 20 to achieve a flipping action of 0°-180°. The flipping platform is also a negative pressure adsorption structure, which is used to fix the finished frame film product by negative pressure adsorption when the second conveying mechanism 13 places the finished frame film product on the flipping platform.

[0073] In this embodiment, the horizontal module 18, vertical module 19, flipping motor 20, flipping spindle 21, and flipping platform work together to achieve both position adjustment and 180° flipping of the frame membrane product, as well as pressing down. These functions work in tandem to provide reliable support for the membrane electrode stack assembly. Specifically, the horizontal module 18 can drive the vertical module 19 and subsequent components to move flexibly along the conveying direction of the conveying mechanism 10. The vertical module 19 can drive the flipping motor 20 and related components to achieve vertical lifting and lowering. Together, they can precisely adjust the spatial position of the flipping platform, ensuring that it can accurately receive the frame membrane product placed by the second transport mechanism 13 and precisely align the flipped frame membrane product with the proton exchange membrane product surface on the conveying mechanism 10. The flipping motor 20 drives the flipping spindle 21 to rotate the flipping platform, stably completing the 180° flipping of the frame membrane product, meeting the adhesion direction requirements of the frame membrane product and the proton exchange membrane product in the membrane electrode stack structure. Simultaneously, the negative pressure adsorption structure used in the flipping platform can firmly fix the frame membrane product in place using negative pressure. The frame membrane is designed to prevent displacement, slippage, or wrinkling during position adjustment and flipping, ensuring its flatness and positional accuracy at all times. Furthermore, the vertical module 19 drives the flipping platform to move the flipped frame membrane downwards, completing the pressing operation. This ensures a tight fit between the frame membrane and the proton exchange membrane below, enhancing the initial bonding and preventing air bubbles or gaps between layers. This guarantees uniform contact and full reaction between the frame membrane and the proton exchange membrane during subsequent curing and sealing processes, thereby improving the sealing performance and structural stability of the membrane electrode assembly. This further ensures the overall performance of the membrane electrode. During the pressing process, the negative pressure adsorption of the flipping platform continues to function, keeping the frame membrane flat and stable, preventing displacement or deformation due to force, and effectively guaranteeing bonding accuracy.

[0074] Both the horizontal module 18 and the vertical module 19 can be linear modules. In this case, the sliding end of the horizontal module 18 and the lifting end of the vertical module 19 are both slide cylinders.

[0075] Specifically, in this embodiment, to further improve the stability and load-bearing capacity of the flipping mechanism 14 in the horizontal direction and ensure the accuracy of the position adjustment of the finished frame membrane, the horizontal module 18 is composed of two parallel linear modules. These two parallel linear modules are arranged in the same direction as the conveying direction of the conveying mechanism 10, and each linear module is equipped with a corresponding slide cylinder. The two slide cylinders move synchronously, jointly carrying and driving the vertical module 19 and the subsequently connected flipping motor 20, flipping main shaft 21, and flipping platform to move smoothly along the conveying direction. This avoids the offset or shaking problems that may occur when a single linear module is carrying the load, and the coordinated drive of the two modules makes the horizontal position adjustment more stable and reliable, providing stronger structural support for the subsequent accurate acceptance of the finished frame membrane and precise alignment of the finished proton exchange membrane. In terms of vertical driving and adjustment, the vertical module 19 is also composed of two parallel linear modules. It is vertically mounted on the two slide cylinders of the horizontal module 18 and keeps synchronous with the two slide cylinders. The connection ensures that when the horizontal module 18 moves the vertical module 19, the vertical module 19 maintains a stable vertical posture. Of the two linear modules in the vertical module 19, one linear module's slide cylinder is fixedly connected to the tilting motor 20 as its power output end, while the other linear module's slide cylinder is connected to the tilting spindle 21. Simultaneously, the tilting motor 20 is also connected to the tilting platform via the tilting spindle 21; that is, one end of the tilting spindle 21 is rigidly connected to the output shaft of the tilting motor 20, and the other end is fixed to one side of the tilting platform. The two slide cylinders... The cylinder synchronous drive jointly drives the flipping motor 20, the flipping main shaft 21, and the flipping platform to rise and fall smoothly in the vertical direction, achieving precise control of the height of the flipping platform. It can rise to a position matching the feeding height of the second conveying mechanism 13 when receiving the finished frame membrane, and can also descend to a height to fit with the finished proton exchange membrane on the conveying mechanism 10 after the finished frame membrane is flipped. It can also provide stable and balanced downward pressure during the fitting process to ensure that the finished frame membrane and the finished proton exchange membrane are tightly fitted. The flipping motor 20 is the power source for realizing the 180° flipping of the finished frame membrane. Its output shaft accurately transmits the rotational power to the flipping platform through the flipping main shaft 21, ensuring that the flipping platform completes the flipping action within the range of 0° to 180° synchronously and smoothly with the flipping main shaft 21, meeting the requirements of the fitting direction of the finished frame membrane in the membrane electrode stack structure.The flipping platform, as the component directly supporting the finished frame membrane, has the same structure as the adsorption platform 15, and will not be described in detail here. When the second conveying mechanism 13 places the finished frame membrane onto the flipping platform, the platform generates a uniform adsorption force through its own structure, firmly fixing the finished frame membrane to the surface. This design not only prevents the finished frame membrane from shifting, slipping, or wrinkling during horizontal movement, vertical lifting, and flipping, ensuring its flatness and positional accuracy, but also allows the finished frame membrane to maintain a stable posture when pressed down after flipping, ensuring precise alignment and tight adhesion with the proton exchange membrane, laying a good foundation for the subsequent curing and sealing process.

[0076] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 5 As shown, the first transport mechanism 12 and the second transport mechanism 13 both have at least five degrees of freedom, and the ends of the first transport mechanism 12 and the second transport mechanism 13 are equipped with a gripping platform 23 and a visual monitoring module 24. The gripping platform 23 is also a negative pressure adsorption structure.

[0077] The first handling mechanism 12 and the second handling mechanism 13 can be robotic arms with multi-axis motion capabilities. Specifically, they can perform translational movements along the X-axis, Y-axis, and Z-axis, as well as rotational movements around at least two rotational axes. Through the combination of these five or more degrees of freedom, they can complete the precise gripping, transfer, and placement of the finished frame membrane or proton exchange membrane.

[0078] The gripping platform 23 can adopt the same structure as the adsorption platform 15 and the flipping platform. It generates negative pressure through uniformly distributed adsorption holes to smoothly adsorb the finished edge membrane or proton exchange membrane, avoiding squeezing damage or edge wrinkles to the thin film products. At the same time, it ensures that the finished edge membrane or proton exchange membrane remains flat and taut during the handling process, providing a basis for accurate alignment during subsequent stacking.

[0079] The visual monitoring module 24 employs an industrial camera paired with an image recognition algorithm to collect real-time information such as the position coordinates and angular deviations of the finished frame membrane or proton exchange membrane. By feeding this data back to the control system, the movement trajectory of the conveying mechanism is dynamically corrected, compensating for minor positional errors when the moving lifting component stops. This ensures that the gripping platform 23 can accurately align with the adsorption area of ​​the finished frame membrane or proton exchange membrane, or precisely place the finished frame membrane or proton exchange membrane at the stacking station of the conveying mechanism 10 during placement, thereby improving the positioning accuracy of the entire transfer and handover process.

[0080] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 6As shown, the first cutting mechanism 6 and the second cutting mechanism 9 both have at least five degrees of freedom, and the ends of the first cutting mechanism 6 and the second cutting mechanism 9 are both equipped with galvanometer processing modules 25.

[0081] The first cutting mechanism 6 and the second cutting mechanism 9 can also be robotic arms with multi-axis motion capabilities, which can flexibly adjust the cutting position, angle and posture to ensure that the cutting operation can be carried out accurately.

[0082] The galvanometer processing module 25 includes a picosecond laser and a galvanometer scanning system. The picosecond laser is used to generate a high-energy-density ultrashort pulse laser beam, and the galvanometer scanning system is used to control the deflection path and focusing position of the laser beam. The two work together to achieve non-contact precision cutting of the edge membrane material or proton exchange membrane material, with no thermal damage or burrs at the cutting edge, meeting the precision requirements of subsequent processes such as lamination, thereby improving the production quality and efficiency of the entire membrane electrode sealing system.

[0083] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the membrane electrode sealing system also includes a charging area 400; at least part of the path markings also lead to the charging area 400, which is equipped with at least three battery swapping stations 26.

[0084] The path formed by the path markers not only leads to the first raw material processing area 100, the second raw material processing area 200 and the continuous bonding and curing area 300, but also extends to the charging area 400, providing clear path guidance for each mobile lifting component to reach the charging area 400.

[0085] The charging area 400 is equipped with at least three battery swapping stations 26, the number of which is matched with the number of mobile support components in the membrane electrode sealing system. When the mobile support component is low on power, it can autonomously move to the battery swapping station 26 along the path leading to the charging area 400 to quickly replenish its energy by swapping the battery, without having to wait for a long time to charge, thus avoiding the interruption of the continuous operation of the entire system due to the depletion of power of a single component.

[0086] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the feed end of the curing mechanism 11 is connected to the discharge end of the conveying mechanism 10. The curing mechanism 11 includes an active heating roller, a driven pressure roller, a temperature control module, and a pressure adjustment module arranged opposite each other in the vertical direction. The roller surface of the active heating roller has an electric heating element built in it. The temperature control module is electrically connected to the electric heating element and is used to adjust the roller surface temperature of the active heating roller to a preset curing temperature. The pressure adjustment module is connected to the driven pressure roller and is used to drive the driven pressure roller to move closer to or further away from the active heating roller in the vertical direction to adjust the pressing pressure between the active heating roller and the driven pressure roller.

[0087] The curing mechanism 11 has its feed end connected to the discharge end of the conveying mechanism 10, forming a continuous processing flow to ensure that the laminated structure conveyed by the conveying mechanism 10 can directly enter the curing mechanism 11. Its core components include an active heating roller and a driven pressure roller arranged vertically opposite each other, as well as a matching temperature control module and pressure regulation module. The active heating roller has an electric heating element inside its surface, and the temperature control module is electrically connected to this element; the pressure regulation module is connected to the driven pressure roller and can drive it to move vertically.

[0088] Specifically, when the laminated structure enters the curing mechanism 11, the active heating roller generates heat through its built-in electric heating element. The temperature control module precisely regulates the roller surface temperature to the preset curing temperature, providing suitable temperature conditions for the curing reaction of the frame membrane and the proton exchange membrane. Simultaneously, the pressure regulating module drives the driven pressure roller closer to the active heating roller, applying a preset pressing pressure to the laminated structure passing between them. Under the synergistic effect of temperature and pressure, the frame membrane and the proton exchange membrane can fully contact and undergo a curing reaction, achieving a tight seal and ultimately forming a structurally stable and reliably packaged membrane electrode product. It should be noted that the setting of the curing temperature and pressing pressure needs to be comprehensively determined based on the material characteristics of the frame membrane used for sealing the membrane electrode, the temperature and pressure resistance limits of the proton exchange membrane, and the actual production requirements for curing efficiency and sealing performance. This application does not impose any limitations on these aspects.

[0089] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0090] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
