Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a continuous packaging device for a rotary fuel cell membrane electrode sealing assembly. 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 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 frame multilayer structures stacked together, in which the cathode catalyst layer, the proton exchange membrane, and the anode catalyst layer constitute the catalytic electrode (formed by uniformly coating the anode catalyst layer and the cathode catalyst layer in an array on the flexible proton exchange membrane).

[0003] At present, the membrane electrode is difficult to mass produce 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 packaging. During this transportation process, it is easy for layers to offset each other. In order 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 positioned membrane electrode needs to be demolded 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 fuel cell membrane electrode and test sample preparation fixture. The hot pressing fixture designed by it positions the proton exchange membrane and edge sealing material through positioning holes, 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 it 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 fuel cell membrane electrode preparation fixture and its processing technology. The fixture designed by it 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 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 components. Summary of the invention

[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 with 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 in 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 the limited state, avoiding misalignment between layers, and finally directly realizing packaging without transfer, which has beneficial characteristics such as packaging continuity and finished product consistency.

[0021] 2. The electrical components of the position sensor and the receiver are arranged in the equipment of the present invention, and are connected with 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, thereby ensuring orderly and efficient work.

[0022] 3. The adsorption mechanism of the present invention comprises 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 the precise positioning effect. 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, opening the adsorption areas in sequence according to the packaging order of the corresponding sealing assembly, it is convenient to control the packaging order of the membrane electrode sealing assembly, thereby 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, the direct contact between the die-cutting head and the heating platform is avoided, thereby 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, and is combined with the servo motor to accurately control the rotation angle of the heating platform to ensure that the heating platform's adsorption of the sealing frame and the diffusion layer is maintained at a uniform 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 change of 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 stepper 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 according to the telescopic column, so as to facilitate the adjustment of the optimal distance between 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 grooves, which are convenient for taking out, placing and storing 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 comprises a catalytic electrode 1-1, two diffusion layers 1-2 and two sealing frames 1-3. The sealing frames 1-3 are provided with through slots 1-3-1 at the center positions. The two diffusion layers 1-2 are respectively placed on the two sides of the catalytic electrode 1-1 to form a membrane electrode. The sealing frames 1-3 are respectively placed on the two sides of the diffusion layer 1-2 to seal the membrane electrode inside. The through slots 1-3-1 are communicated with the non-coated surface of the diffusion layer 1-2. After 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 frames 1-3 are all coincident. Figure 7 The present invention can ensure that the membrane electrode sealing components maintain 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.

[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 telescopic columns 5-2 fixedly connected to the rotating rollers 5-1, and the two catalytic electrode conveying racks 5 realize lifting and lowering movement through the telescopic columns 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 process execution frame 6 driven by a servo motor and rotating around the lifting platform at a fixed angle in a circular array. 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 controlled by a common motor to flip. 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 driving 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 an 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 the 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 through 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 stepping transmission rate and stepping frequency of the catalytic electrode 1-1, so that each catalytic electrode 1-1 coincides with the center line of the die-cutting head 9-3 under the action of stepping transmission. During operation, when the four color sensors all identify the catalytic layer 1-1-1 of the catalytic electrode 1-1, it indicates that the catalytic electrode 1-1 is at 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 to position the catalytic layer 1-1-1 on the catalytic electrode 1-1. When all color sensors recognize the catalytic layer 1-1-1, feedback is given 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 to the position directly below the catalytic layer 1-1-1 of the catalytic electrode 1-1 and is located directly below the cutting mechanism 9.

[0055] like Figure 5As shown, at least one limiting column 9-4 is provided near the corner end of the die-cutting plate 9-2. In this embodiment, four limiting columns 9-4 are 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 columns 9-4 to be fully inserted. The device realizes the positioning and debugging between the die-cutting plate 9-2 and the heating platform 7 through the structures of the limiting holes 9-5 and the limiting columns 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 tool head 9-3 to be embedded.

[0056] In the present device, the heating platform 7 in the first lifting platform 3 can be moved in sequence to the bottom of the catalytic layer 1-1-1 in the catalytic electrode 1-1 during rotation, that is, at this time, 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, after which 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, and a MEA finished product storage box 12 is provided directly below the heating platform 7 in the first lifting platform 3 and the heating platform 7 in the second lifting platform 4 on the frame body 2 where a one-to-one complete overlap is achieved. The heating platform 7 can be rotated according to the angle setting of the servo motor 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, that is, the heating platform 7 can be rotated to the position where its center line coincides 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, and a limiting block 13-2 for the through groove 1-3-1 of the sealing frame 1-3 to pass through is arranged at the center position of the support plate 13-1. A limiting platform 13-3 with the same shape as the limiting block 13-2 and for storing the diffusion layer 1-2 is arranged 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 connected to the inside of the sealed frame storage box 10, the diffusion layer storage box 11, and the MEA finished product storage box 12 along their height direction. 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 frames 1-3, and the adsorption mechanisms 8 of the other heating platforms 7 are all in a closed state. 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 frames 1-3 and the diffusion layer 1-2 in turn during the intermittent rotation at a constant angle, so as to avoid process confusion.

The center line of the sheet diffusion layer 1-2 in the storage state coincides with the center line of the diffusion layer storage box 11 and the limiting platform 13-3. Cut the sealing frame 1-3 into the required size, cut out the through slot 1-3-1 in the center, and 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 rubber surface layer of the sealing frames 1-3 faces downward. At the same time, place the flexible coil 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 it rotates clockwise with a rotation angle of 90° per step, and the four heating platforms A\B\C\D are arranged in counterclockwise order. There are three heating platforms a\b\c on the second lifting platform 4, so it rotates clockwise with a rotation angle of 120° per step, and the three heating platforms a\b\c are arranged in 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 rotate 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 opened, and the adsorption mechanisms 8 in the other heating platforms 7 are all in a closed state.

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 are respectively rotated to the top of the two diffusion layer storage boxes 11, and the heating platform B and heating platform b are respectively rotated to the top of the two sealing frame storage boxes 10, and the position sensors in the 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 are both lowered at the same time, and the PLC system controls the recorded heating platform A and the diffusion layer vacuum adsorption area 8-1 in the heating platform a to open, so as to realize the adsorption of the diffusion layer 1-2, that is, the heating platform A and the heating platform a are adsorbed with the sealing frame 1-3 and the diffusion layer 1-2; at the same time, the sealing frame vacuum adsorption area 8-2 in the heating platform B and the 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 both adsorb the diffusion layer 1-2, heating platform B and heating platform b both adsorb the sealing frame 1-3, they rise at the same time, and then continue to rotate to the next station 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 is flipped 180° during the descent process so that the diffusion layer 1-2 and the sealing frame 1-3 are facing upward, and the catalytic electrode vacuum adsorption area 8-3 in 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 makes the heating platform A rise to the position close to the bottom of the catalytic electrode 1-1, and 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, and then 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, and 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 transmitted, and after the heating platform A with the sealing frame 1-3 and the diffusion layer 1-2 adsorbed arrives at the die-cutting plate 9-2, the catalytic electrode 1-1 is further transmitted so that the catalytic layer 1-1-1 thereon is located directly below the die-cutting head 9-3, and the die-cutting process is performed after all color sensors sense the catalytic layer 1-1-1 on the catalytic electrode 1-1 and the PLC system receives feedback (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.
