Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen fuel cell processing equipment, and in particular to a processing equipment for hydrogen fuel cell membrane electrode. Background Art

[0002] Structurally, the fuel cell system mainly includes the stack, hydrogen supply system, air supply system, water and heat management system, control system, etc. Among them, the stack is the core component of the fuel cell system. It is composed of bipolar plates and membrane electrodes alternately stacked in a single cell series manner. Seals are embedded between each monomer, and the front and rear end plates are pressed and fastened with screws to form a composite. Its research and development and production have high technical barriers; the membrane electrode is mainly composed of three parts of materials: a proton exchange membrane with a catalytic layer, a gas diffusion layer, and a protective frame. Under the corresponding temperature and pressure, these materials are hot pressed into an all-in-one component, which undertakes all the electrochemical reactions of the fuel cell and determines the performance, life and cost of the stack. Therefore, high-performance, low-platinum-loading, low-cost, and long-life membrane electrodes are of great significance to accelerating the commercialization of hydrogen fuel cells.

[0003] It should be noted that when manufacturing the membrane electrode, it is necessary to stack a variety of hot pressing materials (such as a proton exchange membrane with a catalytic layer, a gas diffusion layer, and a protective frame) and then place them in a hot press. The membrane electrode is finally formed through hot pressing of a hot pressing plate. However, during the hot pressing process of the hot press, the hot pressing plate and the membrane electrode are open on all sides. This causes the temperature of the hot pressing plate and the membrane electrode to gradually increase from the outside to the inside. If the external temperature changes, the temperature difference will be more serious. This causes the hot pressing temperature of each part of the membrane electrode to be inconsistent during hot pressing, which in turn leads to the failure to guarantee the hot pressing quality of the membrane electrode, directly causing hidden dangers of failure in later hydrogen fuel cells and causing economic losses. In addition, due to the high temperature of the hot pressing plate, when impurities are scattered on the open hot pressing plate, some impurities will melt quickly, causing the impurities to adhere to the hot pressing plate and be difficult to remove, causing damage to the membrane electrode during hot pressing.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] Please refer to the attached manual Figure 1-14 , a processing device for a hydrogen fuel cell membrane electrode provided by an embodiment of the present invention comprises a hot press body 1, a liftable hot press plate 4 is installed in the hot press body 1, a feed seat 5 and an operation panel 11 are installed on the hot press body 1, a movable base 6 is slidably installed on the feed seat 5, a feed plate 2 is installed on the movable base 6, a discharge plate 3 is placed on the feed plate 2, and a hot pressing material 10 is placed on the discharge plate 3;

[0053] And it also includes a sealing and heat-insulating mechanism 7, which is sleeved on the discharge plate 3 and contacts the bottom side of the hot pressing plate 4, and the sealing and heat-insulating mechanism 7 seals and insulates the hot-pressed material 10 on the discharge plate 3; the sealing and heat-insulating mechanism 7 includes a positioning sleeve 701, which is sleeved on the discharge plate 3, and a limiting strip 711 is installed on one side of the positioning sleeve 701, and two stretching sliders 710 are slidably installed in the limiting strip 711, and the top sides of the two stretching sliders 710 are both installed with sealing covers 702, and an extrusion frame 704 is provided above the sealing cover 702, and the extrusion frame 704 contacts the bottom side of the hot pressing plate 4, and an insulation sleeve 703 is connected between the sealing cover 702 and the extrusion frame 704.

[0054] Furthermore, a processing device for a hydrogen fuel cell membrane electrode provided by an embodiment of the present invention further includes a cleaning and scraping mechanism 8, which is slidably mounted on the top side of the positioning sleeve 701, and is used to scrape and clean the bottom side of the hot pressing plate 4; the cleaning and scraping mechanism 8 includes a wedge-shaped scraping bar 801, and a connecting rod 805 is mounted on one side of the wedge-shaped scraping bar 801, and two receiving boxes 802 are mounted on the connecting rod 805, and the receiving boxes 802 are used to receive impurities scraped off the hot pressing plate 4;

[0055] In addition, in the embodiment of the present invention, it also includes an active heat dissipation mechanism 9, which is rotatably installed on the feeding seat 5, and is used to blow air to dissipate heat to the membrane electrode hot-pressed on the discharge plate 3; the active heat dissipation mechanism 9 includes a flip frame 901, which is rotatably installed on the feeding seat 5, and a cooling fan 902 is installed on the flip frame 901. The flipping of the flip frame 901 drives the cooling fan 902 to blow air to dissipate heat to the membrane electrode hot-pressed.

[0056] It should be noted that, in the embodiment of the present invention, by setting the sealing and heat-insulating mechanism 7, when the hot-pressed material 10 is placed on the discharge plate 3, the two sealing covers 702 are closed and form a closed space with the two heat-insulating sleeves 703. When the feed plate 2 drives the discharge plate 3 to enter the hot press machine body 1, the hot-pressing plate 4 moves down and the extrusion frame 704 moves. At this time, the hot-pressed material 10 is in a closed space, so that the temperature in the closed space formed by the two sealing covers 702 and the two heat-insulating sleeves 703 can be more uniform, thereby ensuring the hot-pressing quality of the hot-pressing material 10 by the hot-pressing plate 4. In addition, by setting the cleaning and scraping mechanism 8, when the hot-pressing plate 4 moves down, the extrusion and pressing rod 815 moves, and the movement of the pressing rod 815 drives the rack 814 to move, and the rack 814 drives the gear 813 to rotate. Then, the power rod 808 is driven to rotate, and the rotation of the power rod 808 drives the rotating column 809 to rotate. The rotating column 809 rotates and squeezes the transfer rod 811 to move through the extrusion driving groove 812. The transfer rod 811 moves and drives the translation sleeve 804 to move. When the translation sleeve 804 moves, it drives the wedge-shaped scraper 801 to move. The wedge-shaped scraper 801 moves to scrape the bottom side of the hot pressing plate 4, and the wedge-shaped scraper 801 can also scrape the bottom side of the hot pressing plate 4 when returning to its position. After the hot pressing plate 4 hot presses the hot pressing material 10, if there are impurities adhering to the bottom side of the hot pressing plate 4, these impurities can be scraped off from the bottom side of the hot pressing plate 4, and the scraped residues fall into the receiving box 802 at the same time, so as to prevent the residues from falling on the hot pressing material 10 or the discharge plate 3, and affecting the quality of the hot pressing material 10.

[0057] It should be further explained that, through the setting of the active heat dissipation mechanism 9, when the feeding plate 2 is reset, the L-shaped frame 907 is squeezed to move, and the movement of the L-shaped frame 907 drives the tooth plate 906 to move, and the movement of the tooth plate 906 drives the driving gear column 905 to rotate, thereby driving the rotating shaft 904 to rotate, and the rotation of the rotating shaft 904 drives the flip frame 901 to flip, and then the flip frame 901 is flipped to the top of the discharge plate 3, and then the heat is dissipated for the membrane electrode hot-pressed on the discharge plate 3. It can not only dissipate the heat of the hot-pressed membrane electrode, but also avoid the problem of overheating of the membrane electrode and the discharge plate 3 to scald the staff when removing the hot-pressed membrane electrode.

[0058] For further information, please refer to the attached manual. Figure 3-7 , a processing device for a hydrogen fuel cell membrane electrode provided by an embodiment of the present invention, the sealing and heat-insulating mechanism 7 further includes four connecting cylinders 715, three connecting cylinders 715 are installed on three sides of the positioning sleeve 701, another connecting cylinder 715 is installed on the limiting bar 711, and a clamping frame 716 is movably installed in the connecting cylinder 715, and the clamping frame 716 is clamped on the feeding plate 2;

[0059] In addition, a pull-back spring 717 is installed on the inner wall of the connecting tube 715, and the other end of the pull-back spring 717 is installed on the clamping frame 716. It should be noted that in the embodiment of the present invention, when installing the positioning sleeve 701, the positioning sleeve 701 is clamped on the discharge plate 3, so that the four clamping frames 716 are squeezed and stretched by the surroundings of the discharge plate 3, and the clamping frames 716 move in the connecting tube 715 and pull the pull-back spring 717 to stretch. Therefore, when the positioning sleeve 701 is clamped on the discharge plate 3, the clamping frame 716 is clamped on the side of the discharge plate 3 under the pull-back force of the pull-back spring 717, so that the positioning sleeve 701 can be easily disassembled.

[0060] To be more specific, in the embodiment of the present invention, sliding grooves 705 are provided on both sides of the positioning sleeve 701, and sliding bars 706 are slidably installed in the sliding grooves 705, and the sliding bars 706 are installed on the extrusion frame 704; in addition, two downward pressing grooves 708 are provided on the top side of the positioning sleeve 701, and two extrusion push rods 707 are installed on the bottom side of the extrusion frame 704, and the bottom ends of the extrusion push rods 707 extend into the downward pressing grooves 708 and are installed with return springs 709, and the bottom ends of the return springs 709 are installed on the bottom inner wall of the downward pressing grooves 708. It should be noted that, in the embodiment of the present invention, when the hot pressing plate 4 continues to move downward and squeezes the extrusion frame 704, the extrusion frame 704 drives the slide bar 706 to slide, and the slide bar 706 slides vertically in the slide groove 705. At the same time, when the extrusion frame 704 moves downward, the extrusion push rod 707 moves downward in the lower pressing groove 708 and drives the return spring 709 to contract, thereby realizing the vertical movement of the extrusion frame 704. When the hot pressing plate 4 is reset, the rebound force of the return spring 709 can help the extrusion push rod 707 to reset, thereby driving the extrusion frame 704 to reset.

[0061] Please continue to refer to the instruction manual Figure 3-7 , more specifically, in the embodiment of the present invention, the inner walls of both sides of the limiting strip 711 are both installed with pull-out springs 718, and the ends of the two pull-out springs 718 close to each other are respectively installed on the two stretching sliders 710;

[0062] In addition, two retraction grooves 712 are provided on the bottom side of the limiting strip 711, and U-shaped locking frames 713 are movably installed in the two retraction grooves 712. Locking slots 719 are provided on the bottom sides of the two open sliding blocks 710, and the two U-shaped locking frames 713 are respectively stuck in the two locking slots 719. A lifting spring 714 is installed on the bottom side of the U-shaped locking frame 713, and the bottom end of the lifting spring 714 is installed on the bottom inner wall of the retraction groove 712. It should be noted that, in the embodiment of the present invention, when the hot pressing plate 4 continues to move downward and squeezes the extrusion frame 704, the extrusion frame 704 drives the slide bar 706 to slide, and the slide bar 706 slides vertically in the slide groove 705. At the same time, when the slide bar 706 moves down into place, the U-shaped locking frame 713 is squeezed to move vertically in the retraction groove 712, and drives the lifting spring 714 to retract, thereby causing the U-shaped locking frame 713 to disengage from the locking slot 719. At this time, under the pulling force of the two pulling springs 718, the two stretching sliders 710 are reset, and the stretching sliders 710 pull the sealing cover 702 to expand, so that the hot pressing plate 4 can fully hot-press the hot pressing material 10 on the discharge plate 3.

[0063] For further information, please refer to the attached manual. Figure 9-13 In an embodiment of the present invention, a processing device for a membrane electrode of a hydrogen fuel cell is provided. A translation groove 803 is provided on the top side of a positioning sleeve 701. A translation sleeve 804 is slidably installed in the translation groove 803. A connecting rod 805 is movably installed in the translation sleeve 804. An extrusion spring 806 is installed at the bottom end of the connecting rod 805. The bottom end of the extrusion spring 806 is installed on the inner wall of the bottom side of the translation sleeve 804. It should be noted that, in the embodiment of the present invention, when the translation sleeve 804 moves, it moves horizontally in the translation groove 803, thereby driving the wedge-shaped scraper 801 to move. The wedge-shaped scraper 801 moves to scrape the bottom side of the hot pressing plate 4, and the wedge-shaped scraper 801 can also scrape the bottom side of the hot pressing plate 4 when returning to its position. Therefore, after the hot pressing plate 4 hot presses the hot pressing material 10, if there are impurities adhering to the bottom side of the hot pressing plate 4, these impurities can be scraped off from the bottom side of the hot pressing plate 4, and the scraped residues fall into the receiving box 802 at the same time, so as to prevent the residues from falling on the hot pressing material 10 or the discharge plate 3, affecting the quality of the hot pressing material 10.

[0068] For further information, please refer to the attached manual. Figure 2 and Fig.14, an embodiment of the present invention provides a processing device for hydrogen fuel cell membrane electrode, a rotating shaft 904 is rotatably installed on the feeding seat 5, and a flip frame 901 is sleeved on the rotating shaft 904; a driving gear column 905 is sleeved on the rotating shaft 904, and a tooth plate 906 is meshed on the driving gear column 905. It should be noted that in the embodiment of the present invention, when the feeding plate 2 is reset, the extrusion L-shaped frame 907 moves, the movement of the L-shaped frame 907 drives the tooth plate 906 to move, and the movement of the tooth plate 906 drives the driving gear column 905 to rotate, thereby driving the rotating shaft 904 to rotate, and the rotation of the rotating shaft 904 drives the flip frame 901 to flip, and then the flip frame 901 flips to the top of the discharge plate 3, thereby dissipating the heat of the membrane electrode formed by hot pressing on the discharge plate 3.

[0069] Please continue to refer to the instruction manual Figure 2 and Fig.14 , further specifically, in the embodiment of the present invention, an L-shaped frame 907 is installed on the tooth plate 906, and the L-shaped frame 907 is movably installed on the feeding seat 5, and the feeding plate 2 is reset to push the L-shaped frame 907 to move;

[0070] In addition, a switch 903 and a return spring 908 are installed on the inner wall of the feed seat 5, the other end of the return spring 908 is installed on the L-shaped frame 907, and the switch 903 is electrically connected to the heat dissipation fan 902. It should be noted that in the embodiment of the present invention, when the feed plate 2 is reset, the L-shaped frame 907 is squeezed to move, thereby driving the return spring 908 to be stressed, and at the same time squeezing and triggering the switch 903, so that the heat dissipation fan 902 is automatically started, so that when the feed plate 2 is reset, the heat dissipation fan 902 is automatically started to blow air and dissipate heat for the hot-pressed membrane electrode, which can not only dissipate heat for the hot-pressed membrane electrode, but also avoid the problem of overheating of the membrane electrode or the discharge plate 3 to scald the staff when the hot-pressed material 10 is removed.

[0071] In summary, the working principle of a processing device for a hydrogen fuel cell membrane electrode provided by an embodiment of the present invention is:

[0072] When the hot pressing material 10 is placed on the discharge plate 3, the two sealing covers 702 are closed and form a closed space with the two insulation sleeves 703. When the feeding plate 2 drives the discharge plate 3 to enter the hot press machine body 1 and the hot pressing plate 4 moves down, the hot pressing material 10 is still in the closed space and the temperature can be maintained, so that the temperature in the closed space formed by the two sealing covers 702 and the two insulation sleeves 703 can be more uniform, thereby ensuring the hot pressing quality of the hot pressing material 10 by the hot pressing plate 4; when the hot pressing plate 4 continues to move down and squeezes the extrusion frame 704, the extrusion frame 704 drives the slide bar 706 to slide, and the slide bar 706 slides vertically in the slide groove 705. At the same time, when the extrusion frame 704 moves down, the top When the lever 707 is in the downward position, the lever 707 moves downward in the downward pressure groove 708, and drives the return spring 709 to contract, thereby realizing the vertical movement of the extrusion frame 704. The extrusion frame 704 drives the slide bar 706 to slide, and the slide bar 706 slides vertically in the slide groove 705. When the slide bar 706 moves down to the right position, the U-shaped locking frame 713 moves vertically in the retraction groove 712, and drives the lifting spring 714 to retract, thereby making the U-shaped locking frame 713 disengage from the locking slot 719. At this time, under the pulling force of the two pulling springs 718, the two stretching sliders 710 are reset, and the stretching sliders 710 pull the sealing cover 702 to expand, thereby making the hot pressing plate 4 can fully hot press the hot pressing material 10 on the discharge plate 3.

[0073] Furthermore, when the hot pressing plate 4 moves downward, the pressing rod 815 is squeezed to move, and the pressing rod 815 moves to drive the rack 814 to move, and the rack 814 drives the gear 813 to rotate, thereby driving the power rod 808 to rotate, and the rotation of the power rod 808 drives the rotating column 809 to rotate, and the rotating column 809 rotates to squeeze the transfer rod 811 through the extrusion driving groove 812 to move, and the transfer rod 811 moves horizontally in the connecting hole 810, thereby driving the translation sleeve 804 to move, thereby realizing the horizontal movement of the translation sleeve 804; similarly, when the rotation column 809 is reset, the translation sleeve 804 is driven to reset through the rotation column 809. When the translation sleeve 804 moves, it moves horizontally in the translation groove 803, thereby driving the wedge-shaped scraper 801 to move. The wedge-shaped scraper 801 moves to scrape the bottom side of the hot pressing plate 4, and the wedge-shaped scraper 801 can also scrape the bottom side of the hot pressing plate 4 when returning to its original position. Therefore, after the hot pressing plate 4 hot presses the hot pressing material 10, if there are impurities adhering to the bottom side of the hot pressing plate 4, these impurities can be scraped off from the bottom side of the hot pressing plate 4, and the scraped residues fall into the receiving box 802 at the same time, so as to prevent the residues from falling on the hot pressing material 10 or the discharge plate 3, affecting the quality of the hot pressing material 10;

[0074] Furthermore, when the feeding plate 2 is reset, the L-shaped frame 907 is squeezed to move, and the movement of the L-shaped frame 907 drives the tooth plate 906 to move, and the movement of the tooth plate 906 drives the driving gear column 905 to rotate, thereby driving the rotating shaft 904 to rotate, and the rotation of the rotating shaft 904 drives the flip frame 901 to flip, thereby making the flip frame 901 flip to the top of the discharge plate 3, and at the same time squeezing and triggering the switch 903, so that the cooling fan 902 is automatically started, so that when the feeding plate 2 is reset, the cooling fan 902 is automatically started to blow air to dissipate heat for the hot-pressed membrane electrode, thereby dissipating the heat of the hot-pressed membrane electrode and avoiding the problem of overheating of the membrane electrode or the discharge plate 3 and scalding the staff when removing the hot-pressed material 10.
