Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a rotary fuel cell membrane electrode sealing assembly continuous packaging device. Background Art

[0002] A fuel cell is a power generation device that converts chemical energy directly into electrical energy through an electrochemical reaction. It has the characteristics of high energy conversion efficiency and environmental friendliness, and is considered to be the preferred clean and efficient power generation technology in the 21st century. The membrane electrode is the place where the electrochemical reaction occurs, and the chemical energy in the fuel is directly converted into electrical energy. The membrane electrode is the core component of the proton exchange membrane fuel cell, and the performance of the membrane electrode directly determines the service life of the battery. The membrane electrode packaging structure is usually a five-in-one structure composed of a multi-layer structure stacked by a cathode gas diffusion layer, a cathode catalyst layer, a proton exchange membrane, an anode catalyst layer, an anode gas diffusion layer, and two outermost sealing frames. The cathode catalyst layer, proton exchange membrane, and anode catalyst layer constitute the catalytic electrode (formed by uniformly coating the anode catalyst layer and cathode catalyst layer in an array on the flexible proton exchange membrane).

[0003] Currently, membrane electrode production is difficult to scale mainly because the three-in-one structure of the catalytic electrode is still a flexible carrier. After the membrane electrode, gas diffusion layer, and sealing frame form a stacked five-in-one packaging structure, it needs to be transported for hot pressing. During this transportation process, it is easy for layers to offset from each other. To reduce the offset error, most of the current membrane electrode five-in-one packaging structures are to sandwich the CCM and edge sealing materials between two layers of stainless steel plates with white paper or plastic film in the middle, and then place them on a hydraulic press for high-temperature pressing. The five-in-one components pressed by this method cannot achieve continuous packaging, and the packaging efficiency is low, and the yield rate is low.

[0004] The patent document with publication number CN110834283A discloses a five-in-one membrane electrode packaging fixture, which uses the fixture to position the five-in-one membrane electrode and then transfer it for hot pressing. This method is relatively simple in principle and practical, but the membrane electrode needs to be demolded after positioning and manually transferred to the hot pressing platform. During the entire process, the membrane electrode is prone to displacement, the yield is relatively low, and the efficiency is slow.

[0005] The patent document with publication number CN102956909B discloses a fixture for preparing fuel cell membrane electrodes and test samples. The hot pressing fixture designed by the patent uses positioning holes to position the proton exchange membrane and edge sealing materials, but it cannot solve the problem that the membrane cannot be laid flat. At the same time, the positioning holes of the fixture designed by the patent need to be fastened by bolts, and the repeated disassembly and assembly of the bolts is time-consuming and labor-intensive. The patent document with publication number CN103811770B discloses a fixture for preparing fuel cell membrane electrodes and its processing technology. The fixture designed by the patent uses dovetail clamps to fix the upper and lower cover plates. Although the operation is relatively simple, the clamping force of the dovetail clamp is small and it is difficult to firmly fix the membrane in the cover plate. At the same time, the products pressed out by the above patents have bubbles in the frame and the frame is easy to warp, resulting in poor flatness, uneven thickness and high defective rate of the five-in-one component. Summary of the Invention

[0006] In response to the technical problems raised above, a continuous packaging device for a rotary fuel cell membrane electrode sealing assembly is provided, which can ensure that the membrane electrode sealing assembly remains in a mutually limited state during the five-in-one process, and can realize continuous transportation until hot pressing molding, thereby ensuring the consistency of the finished product.

An MEA finished product storage box is provided on the frame body directly below the overlapping area of ​​the heating platform in the first lifting platform and the heating platform in the second lifting platform. The heating platform can be rotated to directly above the sealed frame storage box, the diffusion layer storage box, and the MEA finished product storage box.

[0011] Furthermore, the adsorption mechanism includes a diffusion layer vacuum adsorption area arranged in the heating platform, a sealed frame vacuum adsorption area surrounding the diffusion layer vacuum adsorption area, and a catalytic electrode vacuum adsorption area surrounding the sealed frame vacuum adsorption area. The diffusion layer vacuum adsorption area, the sealed frame vacuum adsorption area and the catalytic electrode vacuum adsorption area are respectively connected to the centrifugal fan through an air pipe to achieve single control, and an electromagnetic switch valve is provided on the air pipe.

[0012] Furthermore, the cutting mechanism includes a lifting support platform arranged on the frame body, and a die-cutting plate parallel to the conveying direction of the catalytic electrode is provided on the lifting support platform and located above the catalytic electrode. A die-cutting head for cutting the catalytic electrode is provided on a side of the die-cutting plate close to the catalytic electrode. At least one limiting column is provided near the corner end of the die-cutting plate, and limiting holes for fully inserting the limiting columns are provided on the heating platform. A knife groove for embedding the die-cutting head is provided on the heating platform.

[0013] Furthermore, both the sealed frame storage box and the diffusion layer storage box are provided with a limiting mechanism for the sealed frame and the diffusion layer.

[0014] Furthermore, a support plate is provided at the center position of the sealed frame storage box, a limit block for the through slot of the sealed frame to pass through is provided at the center position of the support plate, and a limit platform with the same shape as the limit block and for storing the diffusion layer is provided at the center position of the diffusion layer storage box.

[0015] Furthermore, the support plate and the limit platform are respectively connected by sliding up and down along the inner walls of the sealed frame storage box and the diffusion layer storage box, and the bottom of the sealed frame storage box and the diffusion layer storage box are fixed with support springs, and the top ends of the support springs are respectively fixedly connected to the bottoms of the support plate and the limit platform.

[0016] Furthermore, the conveying device includes at least two groups of catalytic electrode conveying racks, each of which includes rotating rollers for placing catalytic electrodes and telescopic columns fixedly connected to the rotating rollers. The rotating rollers are controlled by a stepping motor to realize step-by-step conveyance of the catalytic electrodes.

[0017] Furthermore, the sealed frame storage box, the diffusion layer storage box, and the MEA finished product storage box are all provided with opening grooves communicating with the interior of the sealed frame storage box, the diffusion layer storage box, and the MEA finished product storage box along their height directions.

[0018] Furthermore, a position sensor is provided in each of the heating platforms, a receiver connected to the position sensor signal is provided in each of the sealed frame storage boxes, and a color sensor for identifying the catalytic layer in the catalytic electrode is provided in the cutting mechanism.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The equipment of the present invention sequentially adsorbs the sealing frame and the diffusion layer through the adsorption mechanism and the first lifting platform, and then adsorbs and fits the catalytic electrode. At the same time, the heating platform on the second lifting platform sequentially adsorbs the sealing frame and the diffusion layer through the adsorption mechanism. Then the two heating platforms overlap at one point. Through the heating and pressurization of the heating platform, the five-in-one packaging is directly realized, and the continuous process of stacking, transportation, and packaging of the membrane electrode sealing assembly is realized. Under the action of the limiting mechanism, direct limiting is achieved during the stacking process, and it is ensured that there is no contact or movement during the transportation process, so that the membrane electrode sealing assembly maintains continuous transportation in a limited state, avoiding misalignment between layers, and finally directly realizing packaging without transfer, with beneficial characteristics such as packaging continuity and finished product consistency.

[0021] 2. The electrical components of the position sensor and receiver are provided in the equipment of the present invention and are connected to the circuit signal of the PLC system. The signal connection between the position sensor and the receiver can realize the automatic opening and closing of the adsorption mechanism in the heating platform, so that each heating platform on the first lifting platform completes a process in the correct order of adsorption sealing frame, diffusion layer, catalytic electrode and hot pressing, ensuring orderly and efficient work.

[0022] 3. The adsorption mechanism of the present invention includes a vacuum adsorption area for a sealing frame, a vacuum adsorption area for a diffusion layer, and a vacuum adsorption area for a catalytic electrode. Through a single-control connection with a centrifugal fan, the mechanism works in sequence according to the stacking order of the membrane electrode sealing assembly to realize the sequential adsorption and positioning of the sealing frame, the diffusion layer, and the catalytic electrode, thereby ensuring the uniformity of adsorption and precise positioning. At the same time, it can ensure that each layer of the membrane electrode sealing assembly has a higher adsorption pressure when being adsorbed, thereby optimizing the adsorption process and enhancing the adsorption in each area. Furthermore, by controlling the adsorption process of different areas, that is, the adsorption areas need to be opened in sequence according to the packaging order of the sealing assembly, thereby facilitating the control of the packaging order of the membrane electrode sealing assembly and further avoiding the occurrence of process confusion.

[0023] 4. The cutting mechanism of the present invention directly realizes the block cutting of the catalytic electrode, so that the catalytic electrode of fixed size is directly adsorbed on the heating platform. The process is fast and efficient. Under the action of the limiting holes and limiting columns, direct contact between the die-cutting head and the heating platform is avoided, avoiding mutual damage between the two.

[0024] 5. The limiting mechanism of the present invention directly adopts a simple structure of a limiting block and a limiting platform to limit the storage position of the sealing frame and the diffusion layer. Combined with the servo motor, the rotation angle of the heating platform is precisely controlled to ensure that the heating platform maintains the adsorption of the sealing frame and the diffusion layer at a unified central position. That is, the sealing frame and the diffusion layer can be limited at the central position of the heating platform, which solves the problem in the membrane electrode stacking positioning process and greatly improves the membrane electrode packaging efficiency.

[0025] 6. The sealed frame storage box and the diffusion layer storage box of the present invention are both provided with support springs, which can be extended and retracted according to the changes in the gravity borne on the support plate and the limit platform, respectively, to ensure that the heating platform can smoothly adsorb the sealed frame and the diffusion layer.

[0026] 7. The stepping motor of the present invention controls the catalytic electrode to realize step-by-step transmission, ensuring that the cutting mechanism can cut a larger area of ​​the catalytic electrode, avoiding inaccurate transmission positioning and uncontrollable cutting distance, which leads to waste of more catalytic electrodes.

[0027] 8. The catalytic electrode conveying rack of the present invention can also be adjusted up and down by using the telescopic column, so as to facilitate the adjustment of the optimal distance between the catalytic electrode conveying rack and the cutting mechanism and the heating platform.

[0028] 9. The sealed storage box, diffusion layer storage box and MEA finished product storage box of the present invention are all provided with opening slots to facilitate the removal, placement and storage of the sealed frame, diffusion layer and MEA finished products.

[0029] 10. The equipment of the present invention uses continuously rolled catalytic electrodes and adopts a consistent cutting and hot pressing process, which can solve the problems of wrinkles and difficulty in flattening the catalytic electrodes during positioning and packaging. At the same time, it can be connected with roll-to-roll coating equipment, effectively improving the production efficiency of membrane electrodes.

[0030] Based on the above reasons, the present invention can be widely promoted in the fields of membrane electrode large-scale production and the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Example 1

[0050] The present invention provides a continuous packaging device for a rotary fuel cell membrane electrode sealing assembly. The membrane electrode sealing assembly 1 includes a catalytic electrode 1-1, two diffusion layers 1-2, and two sealing frames 1-3. The sealing frames 1-3 are each provided with a through-slot 1-3-1 at the center. The two diffusion layers 1-2 are respectively placed on both sides of the catalytic electrode 1-1 to form a membrane electrode. The sealing frames 1-3 are respectively placed on both sides of the diffusion layer 1-2 to seal the membrane electrode inside. The through-slot 1-3-1 is communicated with the non-coated surface of the diffusion layer 1-2. When the membrane electrode sealing assembly 1 is formed, the center lines of the catalytic electrode 1-1, the diffusion layer 1-2, and the sealing frame 1-3 all coincide. Figure 7 The present invention can ensure that the membrane electrode sealing assembly maintains a mutually limited state during the five-in-one process, and can realize continuous transportation until hot pressing and forming, thereby ensuring the consistency of the finished product.

[0051] This equipment includes a frame 2 and a PLC system, such as Figure 1 and Figure 2As shown, the frame body 2 is provided with a first lifting platform 3, a second lifting platform 4 and two groups of catalytic electrode conveying racks 5 for conveying the flexible coiled material original catalytic electrode 1-1, and the flexible coiled material original catalytic electrode 1-1 is coated with a catalytic layer 1-1-1 in a uniform array; the heating platform 7 of the second lifting platform 4 is higher than the heating platform 7 of the first lifting platform 3; the catalytic electrode conveying racks 5 all include rotating rollers 5-1 for placing the catalytic electrode 1-1, and the rotating rollers 5-1 are controlled by a stepping motor to realize the step-by-step conveyance of the catalytic electrode 1-1, and the catalytic electrode conveying racks 5 also include a telescopic column 5-2 fixedly connected to the rotating roller 5-1, and the two catalytic electrode conveying racks 5 realize the lifting movement through the telescopic column 5-2 to realize the overall height adjustment of the catalytic electrode 1-1 conveying line.

[0052] like Figure 1 and Figure 2 As shown, the first lifting platform 3 and the second lifting platform 4 are both provided with a circumferential array of process execution frames 6 driven by a servo motor and rotating around the lifting platform at a fixed angle. In this embodiment, four process execution frames 6 are provided on the first lifting platform 3, and three process execution frames 6 are provided on the second lifting platform 4. Each process execution frame 6 is rotatably provided with a heating platform 7 that is controlled to flip by a common motor. In this embodiment, a total of four heating platforms 7 are provided on the first lifting platform 3, namely, heating platform A, heating platform B, heating platform C, and heating platform D. A total of three heating platforms 7 are provided on the second lifting platform 4, namely, heating platform a, heating platform b, and heating platform c. Figure 1 and Figure 2 The heating platform 7 is equipped with a dynamic position sensor connected to the PLC system circuit signal, which assists the drive of the stepper motor to enable the PLC system to further identify the heating platform 7 and further control and adjust the position.

[0053] like Figure 3 and 4 As shown, the heating platform 7 is provided with an adsorption mechanism 8 for sequentially grabbing the packaging of the membrane electrode sealing assembly 1. The adsorption mechanism 8 includes a diffusion layer vacuum adsorption area 8-1 arranged in the heating platform 7, a sealing frame vacuum adsorption area 8-2 surrounding the diffusion layer vacuum adsorption area 8-1, and a catalytic electrode vacuum adsorption area 8-3 surrounding the sealing frame vacuum adsorption area 8-2. The diffusion layer vacuum adsorption area 8-1, the sealing frame vacuum adsorption area 8-2, and the catalytic electrode vacuum adsorption area 8-3 are respectively connected to the centrifugal fan 8-5 through the air pipe 8-4 to achieve single control, and the air pipe 8-4 is provided with an electromagnetic switch valve 8-6. The centrifugal fan 8-5 and the electromagnetic switch valve 8-6 are both connected to the PLC system circuit signal in this equipment, and the opening and closing processes of the diffusion layer vacuum adsorption area 8-1, the sealing frame vacuum adsorption area 8-2, and the catalytic electrode vacuum adsorption area 8-3 are controlled in sequence by the program of the PLC system.

[0054] like Figure 1 、 Figure 2 and 5 As shown, the frame body 2 is also provided with a cutting mechanism 9 for acting on the catalytic electrode 1-1, and the cutting mechanism 9 includes a lifting support platform 9-1 arranged on the frame body 2, and a die-cutting plate 9-2 parallel to the conveying direction of the catalytic electrode 1-1 is provided on the lifting support platform 9-1 and located above the catalytic electrode 1-1, and a die-cutting head 9-3 for realizing block cutting of the catalytic electrode 1-1 is provided on the side of the die-cutting plate 9-2 close to the catalytic electrode 1-1, that is, the die-cutting head 9-3 is composed of four blades that can form a frame shape, and the center line of the frame-shaped blade also coincides with the center line of the die-cutting plate 9-2. During the stepping transmission of the stepping motor, the catalytic electrode 1-1 can convey the catalytic layer 1-1-1 in the catalytic electrode 1-1 to the bottom of the die-cutting head 9-3, so that the die-cutting head 9-3 can realize the overall block cutting of the catalytic electrode 1-1; at the same time, in order to accurately control The cutting mechanism 9 is responsible for cutting the catalytic electrode 1-1. A color sensor for identifying the catalytic layer 1-1-1 in the catalytic electrode 1-1 is provided in the die-cutting plate 9-2 of the cutting mechanism 9. Specifically, color sensors connected to the PLC system circuit signal are respectively provided at the four corner ends of the die-cutting plate 9-2. The presence of the color sensor can facilitate the regulation of the step-by-step transmission rate and step-by-step frequency of the catalytic electrode 1-1, so that each catalytic electrode 1-1 is coincident with the center line of the die-cutting head 9-3 under the action of step-by-step transmission. During operation, when all four color sensors recognize the catalytic layer 1-1-1 of the catalytic electrode 1-1, it indicates that the catalytic electrode 1-1 is in the position where it coincides with the center line of the die-cutting head 9-3. At this time, the signal is transmitted to the PLC system, and the die-cutting head 9-3 starts die-cutting through program control. Specifically, when the heating platform rotates to the position directly below the cutting mechanism 9, the catalytic layer 1-1-1 on the catalytic electrode 1-1 is transferred to the position directly below the cutting mechanism 9. After both positions are reached, the PLC system receives feedback and then starts the cutting process. The first lifting platform 3 is rotated at a fixed angle and a fixed frequency by a stepper motor, and the PLC system can control the process of the first lifting platform 3. The PLC system can control the transmission frequency of the catalytic electrode 1-1 and position the catalytic layer 1-1-1 on the catalytic electrode 1-1. When all the color sensors recognize the catalytic layer 1-1-1, feedback is sent to the PLC system, and the PLC system can know that both steps are in place, that is, the catalytic layer 1-1-1 on the catalytic electrode 1-1 is transferred to the position directly below the cutting mechanism 9, and the heating platform is transferred directly below the catalytic layer 1-1-1 of the catalytic electrode 1-1 and is located directly below the cutting mechanism 9.

In this embodiment, four limiting posts 9-4 are provided, evenly distributed near the corner end of the die-cutting plate 9-2. Correspondingly, the heating platform 7 is provided with limiting holes 9-5 for the limiting posts 9-4 to be fully inserted. This device realizes the positioning and debugging between the die-cutting plate 9-2 and the heating platform 7 through the structure of the limiting holes 9-5 and the limiting posts 9-4 to ensure the precise positioning of the two. The heating platform 7 is provided with a knife groove 7-1 for the die-cutting head 9-3 to be embedded.

[0056] In this equipment, the heating platform 7 in the first lifting platform 3 can be moved in sequence while rotating to the bottom of the catalytic layer 1-1-1 in the catalytic electrode 1-1, that is, the center line of the heating platform 7 coincides with the center line of the catalytic layer 1-1-1 of the catalytic electrode 1-1, and then the catalytic electrode 1-1 can be cut and then adsorbed; at the same time, the heating platform 7 in the first lifting platform 3 can achieve a one-to-one complete overlap with the heating platform 7 in the second lifting platform 4. When the two heating platforms 7 completely overlap, the hot pressing process of the membrane electrode sealing assembly 1 is realized.

[0057] like Figure 1 and Figure 2 As shown, at the same time, a sealed frame storage box 10 for storing sealed frames 1-3 and a diffusion layer storage box 11 for storing diffusion layers 1-2 are provided on the frame body 2 below the first lifting platform 3 and the second lifting platform 4 and in sequence along the rotation direction thereof. A MEA finished product storage box 12 is provided directly below the point where the heating platform 7 in the first lifting platform 3 and the heating platform 7 in the second lifting platform 4 completely overlap one to one on the frame body 2. The heating platform 7 can be rotated to the position directly above the sealed frame storage box 10, the diffusion layer storage box 11, the MEA finished product storage box 12, and directly below the die-cutting head 9-3 in the cutting mechanism 9 according to the angle setting of the servo motor, that is, the heating platform 7 can be rotated to the point where its center line overlaps with the center lines of the sealed frame storage box 10, the diffusion layer storage box 11, the MEA finished product storage box 12, and the die-cutting head 9-3 in the cutting mechanism 9.

[0058] In order to make the position between the diffusion layer 1-2 and the sealing frame 1-3 more accurate, the sealing frame storage box 10 and the diffusion layer storage box 11 are both provided with a limiting mechanism 13 for the sealing frame 1-3 and the diffusion layer 1-2. The limiting mechanism 13 includes a support plate 13-1 arranged at the center position of the sealing frame storage box 10, a limiting block 13-2 for the through slot 1-3-1 of the sealing frame 1-3 to pass through is provided at the center position of the support plate 13-1, and a limiting platform 13-3 with the same shape as the limiting block 13-2 and for storing the diffusion layer 1-2 is provided at the center position of the diffusion layer storage box 11, and the length of the limiting platform 13-3 is 1.5mm. The width is 1-2mm larger than the length and width of the limit block 13-2; at the same time, the support plate 13-1 and the limit platform 13-3 are respectively connected by sliding up and down along the inner wall of the sealed frame storage box 10 and the diffusion layer storage box 11, and the bottom of the sealed frame storage box 10 and the diffusion layer storage box 11 are fixed with a support spring 14, and the top of the support spring 14 is respectively fixedly connected to the bottom of the support plate 13-1 and the limit platform 13-3, and the sealed frame storage box 10, the diffusion layer storage box 11, and the MEA finished product storage box 12 are provided with an opening groove 15 along their height direction that communicates with the inside of the sealed frame storage box 10, the diffusion layer storage box 11, and the MEA finished product storage box 12, such as Figure 6 shown.

[0059] In order to realize the automation of each process in this equipment, a position sensor (not shown in the figure) connected to the PLC system circuit signal is provided in the heating platform 7, and a receiver connected to the position sensor signal is provided in the sealing frame storage box 10. That is, when the position sensor receives the signal from the receiver, the PLC system program controls the adsorption mechanism 8 of the heating platform 7 to open, so as to realize the adsorption of the sealing frame 1-3. The adsorption mechanisms 8 of the other heating platforms 7 are all in a closed state, and the sealing frame storage box 10 is the starting position of this process, thereby ensuring that each heating platform 7 can realize the adsorption of the sealing frame 1-3 and the diffusion layer 1-2 in turn during the intermittent rotation at a constant angle, thereby avoiding process confusion.

[0060] Example 2

[0061] Based on Example 1, the present invention further provides a continuous packaging process for a rotary fuel cell membrane electrode sealing assembly continuous packaging device, comprising the following steps:

[0062] S1. Stack the sheet-like diffusion layers 1-2 on the limiting platform 13-3 in the diffusion layer storage box 11. The center lines of the sheet-like diffusion layers 1-2 in the storage state coincide with the center lines of the diffusion layer storage box 11 and the limiting platform 13-3. Cut the sealing frame 1-3 into the required size, and cut out the through-slot 1-3-1 in the center. Then, place a large number of sealing frames 1-3 on the support plate 13-1 in the sealing frame storage box 10. At the same time, the through-slots 1-3-1 of the sealing frames 1-3 all pass through the limiting block 13-2, and the adhesive surface layer of the sealing frames 1-3 faces downward. At the same time, place the flexible coiled catalytic electrode 1-1 coated with the catalytic layer 1-1-1 in the catalytic electrode conveying rack 5 and wait for conveyance.

[0063] S2, the first lifting platform 3, and the second lifting platform 4 all realize synchronous and unidirectional intermittent circular rotation under the angle parameter setting of the servo motor, such as Figure 8 As shown, there are four heating platforms A\B\C\D on the first lifting platform 3, so they are rotated clockwise with a rotation angle of 90° per step, and the four heating platforms A\B\C\D are arranged in a counterclockwise order. There are three heating platforms a\b\c on the second lifting platform 4, so they are rotated clockwise with a rotation angle of 120° per step, and the three heating platforms a\b\c are arranged in a counterclockwise order. The heating platform A and the heating platform a directly above the sealed frame storage box 10 are the starting ends. When the heating platform A and the heating platform a are rotated to the positions directly above the two sealed frame storage boxes 10 respectively, when the position sensors in the heating platform A and the heating platform a receive the receiver signals from the sealed frame storage box 10, the PLC system controls the sealed frame vacuum adsorption area 8-2 of the heating platform A and the heating platform a to be continuously open, and the adsorption mechanisms 8 in the other heating platforms 7 are all in a closed state.

[0064] S3, the first lifting platform 3, and the second lifting platform 4 are all completely lowered at the same time, and the heating platform A and the heating platform a realize the adsorption of the sealing frame 1-3. At the same time, the PLC system records the heating platform with the sealing frame 1-3 adsorbed.

[0065] S4, after both heating platform A and heating platform a adsorb the sealing frame 1-3, they rise at the same time, and then both continue to rotate at the same time. The heating platform A and heating platform a adsorbed with the sealing frame 1-3 rotate to the top of the two diffusion layer storage boxes 11 respectively, and the heating platform B and heating platform b rotate to the position directly above the two sealing frame storage boxes 10 respectively. The position sensors in heating platform B and heating platform b receive the receiver signal from the sealing frame storage box 10; the first lifting platform 3 and the second lifting platform 4 both descend at the same time, and the PLC system controls the recorded diffusion layer vacuum adsorption area 8-1 in heating platform A and heating platform a to open, so as to realize the adsorption of the diffusion layer 1-2, that is, the sealing frame 1-3 and the diffusion layer 1-2 are adsorbed on both heating platform A and heating platform a; at the same time, the sealing frame vacuum adsorption area 8-2 in heating platform B and heating platform b is controlled to open, so as to realize the adsorption of the sealing frame 1-3; the PLC system records again.

[0066] S5, after heating platform A and heating platform a adsorb the diffusion layer 1-2, heating platform B and heating platform b adsorb the sealing frame 1-3, they rise at the same time, and then continue to rotate to the next workstation at the same time, and then descend as a whole again, so that the remaining heating platforms 7 at the rear can realize the material absorption process, wherein heating platform B and heating platform b are controlled to adsorb the diffusion layer 1-2, and heating platform C and heating platform c are controlled to adsorb the sealing frame 1-3, and heating platform A of the first lifting platform 3, which is transferred to the catalytic electrode 1-1 and located directly below the die-cutting plate 9-2, flips 180° during the descent process until the diffusion layer 1-2 and the sealing frame 1-3 are facing upward, and the catalytic electrode vacuum adsorption area 8-3 in the heating platform A is opened; when heating platform B and heating platform b complete the adsorption of the diffusion layer 1-2, and heating platform C and heating platform c complete the adsorption of the sealing frame 1-3, the first lifting platform 3 and the second lifting platform 4 both rise as a whole, and the first lifting platform 3 raises the heating platform A to a position close to and directly below the catalytic electrode 1-1. After the heating platforms on the second lifting platform 4 are all raised to a position higher than the heating platforms of the first lifting platform 3, they stop rotating under the control of the PLC system and are in a waiting state. That is, at this time, the rotation of the second lifting platform 4 needs to wait for a process time at the first lifting platform 3. The specific waiting time can be calculated by the PLC system program according to the actual debugging stage; at the same time, the catalytic electrode 1-1 starts to be transported. After the heating platform A with the sealing frame 1-3 and the diffusion layer 1-2 adsorbed thereon reaches the die-cutting plate 9-2, the catalytic electrode 1-1 is further transported so that the catalytic layer 1-1-1 thereon is located directly below the die-cutting head 9-3. After all color sensors sense the catalytic layer 1-1-1 on the catalytic electrode 1-1 and the PLC system receives feedback, the die-cutting process is carried out (in the control stage, this waiting time can be recorded by the PLC system and the step transmission frequency of the catalytic electrode 1-1 can be set accordingly).

[0067] S6. After all the color sensors in the die-cutting board 9-2 sense the catalytic layer 1-1-1 on the catalytic electrode 1-1, the die-cutting board 9-2 is driven down by the lifting support platform 9-1 to achieve block cutting of the catalytic electrode 1-1 at this position. The cut catalytic electrode 1-1 is adsorbed on the heating platform A and covers the sealing frame 1-3 and the diffusion layer 1-2.

[0068] S7. The heating platform A on the first lifting platform 3, on which the sealing frame 1-3, the diffusion layer 1-2 and the catalytic electrode 1-1 are adsorbed, rotates to the position directly below the heating platform a on the second lifting platform 4 described in S5, on which the sealing frame 1-3 and the diffusion layer 1-2 are adsorbed (at the same time, the heating platform B on which the sealing frame 1-3 and the diffusion layer 1-2 are adsorbed rotates to the position directly below the catalytic electrode 1-1). The second lifting platform 4 descends rapidly to achieve complete overlap between the heating platform A and the heating platform a. The two heating platforms achieve five-in-one hot pressing packaging between the sealing frame 1-3 and the diffusion layer 1-2 on the second lifting platform 4 and the catalytic electrode 1-1, the diffusion layer 1-2 and the sealing frame 1-3 on the first lifting platform 3. The hot pressing temperature is 100°C and the time is 30s, completing the membrane electrode sealing assembly 1.

[0069] S8. After completing S8, the second lifting platform 4 begins to rise and closes its adsorption mechanism 8, moving away from the first lifting platform 3. The heating platform A carrying the membrane electrode sealing assembly 1 in the first lifting platform 3 quickly flips 180° counterclockwise during the rising process of the second lifting platform 4, and at the same time closes the adsorption mechanism 8 therein, so that the packaged membrane electrode falls into the MEA finished product storage box 12 directly below it.

[0070] S9. The first lifting platform 3 then descends, controlling heating platform C to adsorb the diffusion layer 1-2 and heating platform D to adsorb the sealing frame 1-3. Heating platform B, which adsorbs the sealing frame 1-3 and diffusion layer 1-2, flips 180° during descent, so that both the diffusion layer 1-2 and the sealing frame 1-3 face upward. The catalytic electrode vacuum adsorption area 8-3 in heating platform B is opened. Simultaneously, the second lifting platform 4 rotates 120° before descending. Heating platform B, which adsorbs the sealing frame 1-3 and diffusion layer 1-2, rotates to directly above the MEA finished product storage box 12. Heating platform C adsorbs the diffusion layer 1-2, and heating platform A adsorbs the sealing frame 1-3. The first lifting platform 3 and the second lifting platform 4 are both raised as a whole. The first lifting platform 3 raises the heating platform B to a position close to and directly below the catalytic electrode 1-1. After the heating platforms on the second lifting platform 4 are raised to a position higher than the heating platform of the first lifting platform 3, they stop rotating under the control of the PLC system and enter a waiting state. The catalytic electrode 1-1 begins to be transported. After the heating platform B with the sealing frame 1-3 and the diffusion layer 1-2 adsorbed thereon reaches the die-cutting plate 9-2, the catalytic electrode 1-1 is further transported so that the catalytic layer 1-1-1 thereon is directly below the die-cutting head 9-3. After all color sensors sense the catalytic layer 1-1-1 on the catalytic electrode 1-1 and the PLC system receives feedback, the die-cutting process is carried out. Step S6 is repeated, and the cut catalytic electrode 1-1 is adsorbed on the heating platform B and covers the sealing frame 1-3 and the diffusion layer 1-2.

[0071] S10. The heating platform B on the first lifting platform 3, which has the sealing frame 1-3, diffusion layer 1-2, and catalytic electrode 1-1 adsorbed thereon, rotates to a position directly below the heating platform B on the second lifting platform 4 described in S9, which has the sealing frame 1-3 and diffusion layer 1-2 adsorbed thereon (simultaneously, the heating platform C, which has the sealing frame 1-3 and diffusion layer 1-2 adsorbed thereon, rotates to a position directly below the catalytic electrode 1-1). The second lifting platform 4 rapidly descends, completely aligning the heating platforms B and B, achieving a five-in-one hot-pressing package at a temperature of 100°C for 30 seconds, completing the membrane electrode sealing assembly 1. Repeat S8, and the packaged membrane electrode on heating platform B falls into the MEA finished product storage box 12 directly below it.

[0072] S11. The first lifting platform 3 then descends, controlling heating platform D to adsorb the diffusion layer 1-2 and heating platform A to adsorb the sealing frame 1-3. Heating platform C, which adsorbs the sealing frame 1-3 and diffusion layer 1-2, flips 180° during its descent so that both the diffusion layer 1-2 and the sealing frame 1-3 face upward, and the catalytic electrode vacuum adsorption area 8-3 in heating platform C is opened. Simultaneously, the second lifting platform 4 rotates 120° before descending. Heating platform C, which adsorbs the sealing frame 1-3 and diffusion layer 1-2, rotates to directly above the MEA finished product storage box 12. Heating platform A adsorbs the diffusion layer 1-2, and heating platform B adsorbs the sealing frame 1-3. The first lifting platform 3 and the second lifting platform 4 are both raised as a whole. The first lifting platform 3 raises the heating platform C to a position close to and directly below the catalytic electrode 1-1. After the heating platforms on the second lifting platform 4 are raised to a position higher than the heating platform of the first lifting platform 3, they stop rotating under the control of the PLC system and enter a waiting state. The catalytic electrode 1-1 begins to be transported. After the heating platform C with the sealing frame 1-3 and the diffusion layer 1-2 adsorbed thereon reaches the die-cutting plate 9-2, the catalytic electrode 1-1 is further transported so that the catalytic layer 1-1-1 thereon is directly below the die-cutting head 9-3. After all color sensors sense the catalytic layer 1-1-1 on the catalytic electrode 1-1 and the PLC system receives feedback, the die-cutting process is carried out. Step S6 is repeated, and the cut catalytic electrode 1-1 is adsorbed on the heating platform C and covers the sealing frame 1-3 and the diffusion layer 1-2.

[0073] S12. The heating platform C on the first lifting platform 3, which has the sealing frame 1-3, diffusion layer 1-2, and catalytic electrode 1-1 adsorbed thereon, rotates to a position directly below the heating platform C on the second lifting platform 4 described in S11, which has the sealing frame 1-3 and diffusion layer 1-2 adsorbed thereon (simultaneously, the heating platform D on which has the sealing frame 1-3 and diffusion layer 1-2 adsorbed thereon rotates to a position directly below the catalytic electrode 1-1). The second lifting platform 4 rapidly descends, completely aligning the heating platforms C and D, achieving a five-in-one hot-pressing package at a temperature of 100°C for 30 seconds, completing the membrane electrode sealing assembly 1. Repeat S8, and the packaged membrane electrode on heating platform C falls into the MEA finished product storage box 12 directly below it.

[0074] S13. The first lifting platform 3 then descends, controlling heating platform A to adsorb the diffusion layer 1-2 and heating platform B to adsorb the sealing frame 1-3. Heating platform D, which adsorbs the sealing frame 1-3 and diffusion layer 1-2, flips 180° during descent so that both the diffusion layer 1-2 and the sealing frame 1-3 face upward, and the catalytic electrode vacuum adsorption area 8-3 in heating platform D is opened. Simultaneously, the second lifting platform 4 rotates 120° before descending. Heating platform A, which adsorbs the sealing frame 1-3 and diffusion layer 1-2, rotates to directly above the MEA finished product storage box 12. Heating platform B adsorbs the diffusion layer 1-2, and heating platform C adsorbs the sealing frame 1-3. The first lifting platform 3 and the second lifting platform 4 are both raised as a whole. The first lifting platform 3 raises the heating platform D to a position close to and directly below the catalytic electrode 1-1. After the heating platforms on the second lifting platform 4 are raised to a position higher than the heating platform of the first lifting platform 3, they stop rotating under the control of the PLC system and enter a waiting state. The catalytic electrode 1-1 begins to be transported. After the heating platform D with the sealing frame 1-3 and the diffusion layer 1-2 adsorbed thereon reaches the die-cutting plate 9-2, the catalytic electrode 1-1 is further transported so that the catalytic layer 1-1-1 thereon is directly below the die-cutting head 9-3. After all color sensors sense the catalytic layer 1-1-1 on the catalytic electrode 1-1 and the PLC system receives feedback, the die-cutting process is carried out. Step S6 is repeated, and the cut catalytic electrode 1-1 is adsorbed on the heating platform D and covers the sealing frame 1-3 and the diffusion layer 1-2 directly above.

[0075] S14. The heating platform D on the first lifting platform 3, which has the sealing frame 1-3, diffusion layer 1-2, and catalytic electrode 1-1 adsorbed thereon, rotates to the position directly below the heating platform a on the second lifting platform 4 described in S13, which has the sealing frame 1-3 and diffusion layer 1-2 adsorbed thereon (simultaneously, the heating platform A on which the sealing frame 1-3 and diffusion layer 1-2 are adsorbed rotates to the position directly below the catalytic electrode 1-1). The second lifting platform 4 descends rapidly, achieving complete overlap between heating platform D and heating platform a, and completing the five-in-one hot pressing packaging. The hot pressing temperature is 100°C, and the time is 30 seconds, completing the membrane electrode sealing assembly 1. Repeat S8, and the packaged membrane electrode on heating platform D falls into the MEA finished product storage box 12 directly below it. Repeat the above steps to finally achieve continuous packaging of the fuel cell membrane electrode.

[0076] S10. After the continuous packaging is completed, the first lifting platform 3 and the second lifting platform 4 open the adsorption mechanism 8 at the same time to cool the platform. When the heating platform A of the first lifting platform 3 and the heating platform a of the second lifting platform 4 run to the top of the two sealed frame storage boxes 10, they return to the initial position, close the adsorption mechanism 8, and the entire equipment stops working, waiting for the next continuous packaging of the fuel cell membrane electrode.

[0077] During the above working process, the PLC system controls the opening and closing and sequential actions of all components throughout the process, ensuring that the adsorption function on each heating platform 7 is turned on and adsorbed in the order of the sealing frame 1-3, the diffusion layer 1-2, and the catalytic electrode 1-1, that is, ensuring that the sealing frame 1-3, the diffusion layer 1-2, and the catalytic electrode 1-1 can all be adsorbed on each heating platform 7 in turn. At the same time, the coordinated control between the PLC system and various sensors can adjust and control the stepping rotation speed, stepping frequency, and lifting direction / height of the first lifting platform 3 and the second lifting platform 4 according to the actual number of heating platforms 7, so as to realize the correct operation of multiple processes.

[0079] In this embodiment, four process execution frames 6 are provided on the first lifting platform 3, and four process execution frames 6 are provided on the second lifting platform 4. Each process execution frame 6 is provided with a rotating heating platform 7 that is flipped and controlled by a common motor. There are four heating platforms 7 on the first lifting platform 3, namely heating platform A, heating platform B, heating platform C, and heating platform D. There are four heating platforms 7 on the second lifting platform 4, namely heating platform a, heating platform b, heating platform c, and heating platform d.
