Abstract
Description
Technical Field
[0001] This invention relates to the field of hydrogen fuel cell production technology, specifically to an assembly equipment for the production of automotive hydrogen fuel cells. Background Technology
[0002] Fuel cells, especially proton exchange membrane fuel cells, are the core power source for hydrogen fuel cell vehicles. The quality of their stack assembly directly determines the performance, efficiency, and lifespan of the cells. A fuel cell stack consists of dozens to hundreds of individual cells (membrane electrode and bipolar plate) stacked alternately. The assembly process requires extremely high alignment precision and uniform pressing force. Existing fuel cell production equipment, especially the stack assembly stage, generally suffers from the following technical defects: 1. Existing automated stacking equipment mostly uses robotic arms to pick up and place each cell one by one. Due to the positioning error of the robotic arm, the tolerance of the workpiece itself, and the micro-movement during the placement process, the slight misalignment of a single battery module will form a significant cumulative error after multiple layers are stacked, resulting in misalignment of the reaction gas flow channel and sealing failure, which in turn leads to a decrease in battery performance and leakage risk. Although some equipment has introduced a high-precision visual positioning system and a complex correction mechanism, it is still difficult to avoid the slight deviation caused by factors such as vibration, which affects the stacking accuracy. 2. When the stacked fuel cells are finally pressed and tightened, traditional presses only apply pressure in the vertical direction. Under high pressure, the soft membrane electrodes and seals inside the fuel cell will expand laterally, causing the middle of the entire fuel cell to bulge outward, i.e., "bulging" deformation. This deformation will result in insufficient sealing pressure at the edge of the fuel cell, while the central area may be damaged by excessive compression of the membrane electrodes, seriously impairing the consistency and reliability of the fuel cell. Summary of the Invention
[0003] The purpose of this invention is to provide an assembly device for the production of automotive hydrogen fuel cells, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an assembly equipment for the production of automotive hydrogen fuel cells, comprising a workbench, a gantry frame fixed on the workbench, a pressing mechanism for pressing hydrogen fuel cells installed on the gantry frame, and second cylinders symmetrically fixed on the workbench, the output end of the second cylinders being fixed to a support plate, the support plate being fixed on a movable frame, and a stacking mechanism installed on the movable frame; An alignment mechanism is used to automatically correct and align each hydrogen fuel cell assembly after stacking, and to provide lateral support when the hydrogen fuel cell assemblies are pressed together. The alignment mechanism is mounted on a mobile frame. A positioning mechanism is used to position the alignment mechanism during the pressing of hydrogen fuel cell components. The positioning mechanism is mounted on a movable frame.
[0005] Preferably, guide rails are symmetrically fixed on the upper surface of the worktable, and a fixed inclined block is fixed on the worktable. The upper surface of the inclined block is located directly below the pressing mechanism. The above structure can ensure the normal operation of the device.
[0006] Preferably, the pressing mechanism includes a first cylinder fixed on the gantry, and a fixed plate is fixed to the output end of the first cylinder, and a first inclined plate is fixed to the side of the fixed plate. The inclined angle of the first inclined plate is 45°. The extension and retraction of the first cylinder can provide a basic force for the movement of the fixed plate and the first inclined plate.
[0007] Preferably, the fixed plate and the vertical rod are slidably connected, and the lower end of the vertical rod is fixed to the pressure plate. A pressure sensor is fixed on the pressure plate, and a first spring is fixed between the pressure sensor and the fixed plate. Through the sliding action between the fixed plate and the vertical rod, the fixed plate can move relative to the pressure plate. Combined with the elastic action of the first spring, it can provide a basic force for the automatic reset of the fixed plate.
[0008] Preferably, the lower end face of the movable frame is symmetrically fixed with sliders, and the sliders are slidably connected to the guide rail. When the movable frame moves, the sliding guidance between the sliders and the guide rail can ensure the stability of the movable frame's movement.
[0009] Preferably, the stacking mechanism includes a motor fixed on a movable frame, and a threaded rod is fixed to the output end of the motor. The threaded rod is connected to the movable frame by a bearing, and the threaded rod is connected to the horizontal plate by a thread. A slide rod is fixed to the horizontal plate, and the slide rod is slidably connected to the movable frame. A support plate is fixed to the upper end of the slide rod. The motor drives the threaded rod to rotate, which, together with the threaded connection between the threaded rod and the horizontal plate, provides a basic force for the downward movement of the support plate. Combined with the sliding guide effect between the slide rod and the movable frame, the stability of the downward movement of the support plate can be ensured.
[0010] Preferably, the alignment mechanism includes a disc fixed on a threaded rod, and an arc-shaped block is fixed at an angle on the disc. The arc-shaped block and the roller form a rolling connection, and the roller bearing is connected to the frame. At the same time, the frame bearing is connected to a roller. The disc is rotated by the threaded rod. Combined with the sliding action between the arc-shaped block and the roller, it can provide a basic force for the movement of the frame, thereby providing a basic guarantee for the alignment and correction of the hydrogen fuel cell components after stacking.
[0011] Preferably, one end of the frame and the crossbar are fixed to each other, and the other end of the crossbar is fixed to the fixed frame. A guide rod is fixed on the fixed frame, and the guide rod is slidably connected to the support plate. A second spring is fixed between the support plate and the guide rod. When the frame moves the crossbar and the fixed frame, the sliding guidance between the guide rod and the support plate can ensure the stability of the fixed frame's movement. Combined with the elasticity of the second spring, it can provide a basic force for the automatic reset of the fixed frame, thereby ensuring the normal operation of the device.
[0012] Preferably, a top plate is fixed to the upper end of the fixing frame, and a round rod is fixed to the top plate. The round rod is slidably connected to the mounting plate, and a third spring is fixed between the mounting plate and the top plate. A round rod is connected to a bearing on the round rod, and the round rod is slidably connected to the first inclined plate. The distance between the lower end face of the top plate and the movable frame is equal to the thickness of the support plate. Through the action of the top plate, a basic force can be provided for the alignment and correction of the hydrogen fuel cell assembly after stacking. Through the sliding action between the round rod and the first inclined plate, lateral pressure can be provided for the pressing of the hydrogen fuel cell assembly after stacking, ensuring the normal pressing process.
[0013] Preferably, the positioning mechanism includes a ring disposed on the outside of the motor, with an inclined plate fixed on the ring and a rolling connection between the inclined plate and the roller. A support rod is fixed to the lower end of the ring, and the support rod is slidably connected to the movable frame. A base plate is fixed to the lower end of the support rod, and a fourth spring is fixed between the base plate and the movable frame. A round shaft is connected to the lower end face of the base plate via a bearing, and the round shaft is rollingly connected to the fixed inclined block. The rolling action between the round shaft and the fixed inclined block provides a basic force for the movement of the inclined plate. Combined with the rolling action between the inclined plate and the roller, it provides a basic guarantee for the positioning of the top plate. Furthermore, the elastic action of the fourth spring provides a basic guarantee for the automatic reset of the inclined plate, thereby ensuring the normal operation of the device.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This assembly equipment for the production of automotive hydrogen fuel cells, through the mechanical linkage between the stacking mechanism and the alignment mechanism (the motor drives the threaded rod to move the tray downward while driving the disk to rotate and trigger the top plate to move), ensures that the system automatically performs a correction action for each stacked battery module, thereby ensuring that each module is straightened after stacking. The subsequent stacked modules are all based on the aligned modules, resulting in extremely high flow channel alignment accuracy of the final fuel cell stack, effectively ensuring uniform gas distribution and sealing reliability. Moreover, the process is fully automated, requiring no manual intervention or complex visual inspection, thus better meeting actual production needs. 2. This assembly equipment for the production of automotive hydrogen fuel cells utilizes a secondary linkage between the pressing mechanism and the alignment mechanism (when the pressing head presses down, the first inclined plate acts on the round rod, and the top plate generates lateral pressure through the spring). This utilizes the vertical downward pressure required for pressing as a power source to synchronously and automatically generate a lateral constraint force proportional to it. The tighter the pressing, the greater the lateral constraint force, achieving dynamic and adaptive lateral support. This effectively prevents lateral deformation of the fuel cell stack during the pressing process, ensures uniform stress inside the fuel cell stack, and greatly improves the pressing quality and product consistency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-7 The present invention provides a technical solution: an assembly equipment for the production of automotive hydrogen fuel cells, including a workbench 1, a gantry frame 2 fixed on the workbench 1, a pressing mechanism 3 for pressing hydrogen fuel cells installed on the gantry frame 2, and second cylinders 4 symmetrically fixed on the workbench 1. The output end of the second cylinder 4 is fixed to a support plate 502. The support plate 502 is fixed on a movable frame 5, and a stacking mechanism 6 is installed on the movable frame 5. Alignment mechanism 7 is used to automatically correct and align each hydrogen fuel cell assembly after stacking, and also provides lateral support when the hydrogen fuel cell assembly is pressed together. Alignment mechanism 7 is mounted on mobile frame 5. The positioning mechanism 8 is used to position the alignment mechanism 7 during the pressing of the hydrogen fuel cell assembly. The positioning mechanism 8 is mounted on the movable frame 5.
[0019] The stacking mechanism 6 includes a motor 601 fixed on the movable frame 5, and a threaded rod 602 is fixed at the output end of the motor 601. The threaded rod 602 is connected to the movable frame 5 by a bearing, and the threaded rod 602 is connected to the horizontal plate 603 by a thread. A slide rod 604 is fixed on the horizontal plate 603, and the slide rod 604 is slidably connected to the movable frame 5. A support plate 605 is fixed at the upper end of the slide rod 604. When using assembly equipment for the production of automotive hydrogen fuel cells, such as Figures 1-7 As shown, a robotic arm sequentially stacks the hydrogen fuel cell modules onto a pallet 605 (the dimensions of the hydrogen fuel cell modules and the pallet 605 are equal). During the stacking process of each hydrogen fuel cell module, after one module is placed, the motor 601 drives the threaded rod 602 to rotate one revolution. In conjunction with the threaded connection between the threaded rod 602 and the horizontal plate 603, the horizontal plate 603, the sliding rod 604, and the pallet 605 can be moved down a certain distance. With the sliding guide between the sliding rod 604 and the moving frame 5, the stability of the pallet 605's downward movement can be ensured. The downward distance of the pallet 605 is equal to the height of the hydrogen fuel cell module, thus ensuring that the stacking height of the next hydrogen fuel cell module remains unchanged after each stacking, so as to facilitate the subsequent stacking of hydrogen fuel cell modules. The alignment mechanism 7 includes a disc 701 fixed to a threaded rod 602, with an arc-shaped block 702 fixed at an angle on the disc 701. The arc-shaped block 702 and a roller 703 are in a rolling connection, and the roller 703 is bearing-connected to a frame 704. A roller 705 is also bearing-connected to the frame 704. The frame 704 is fixed to one end of a crossbar 706, and the other end of the crossbar 706 is fixed to a fixing frame 707. A guide rod 708 is fixed to the fixing frame 707, and the guide rod 708 is connected to the support plate 502. A sliding connection is established, with a second spring 709 fixed between the support plate 502 and the guide rod 708; a top plate 710 is fixed to the upper end of the fixed frame 707, and a round rod 711 is fixed on the top plate 710, with a sliding connection between the round rod 711 and the mounting plate 713, while a third spring 712 is fixed between the mounting plate 713 and the top plate 710; a round rod 714 is connected to the round rod 711 by a bearing, and the round rod 714 is rolled to the first inclined plate 303; the distance between the lower end face of the top plate 710 and the movable frame 5 is equal to the thickness of the support plate 605. During the stacking of hydrogen fuel cell components, such as Figures 1-7 As shown, when the motor 601 drives the threaded rod 602 to rotate one revolution to achieve height adjustment, the threaded rod 602 drives the disc 701 to rotate one revolution synchronously. The rotation of the disc 701 drives the arc block 702 to rotate. When the roller 703 contacts and rolls against the arc block 702, the frame 704, crossbar 706, fixing frame 707, and top plate 710 are moved under force. Combined with the sliding guidance between the guide rod 708 and the support plate 502, the stability of the movement of the frame 704, crossbar 706, fixing frame 707, and top plate 710 is ensured. When the roller 703 contacts the highest point of the arc block 702, the top plate 710 contacts the support plate 605. If the hydrogen fuel cell assembly is stacked on the support plate 605, then the top plate 710 is in contact with the hydrogen fuel cell assembly. When the hydrogen fuel cell assembly is tilted while stacked on the pallet 605, the top plate 710 can automatically correct and straighten it. After the disk 701 rotates one revolution, the top plate 710 separates from the pallet 605 to allow the stacked hydrogen fuel cell assembly to be lowered. Based on the above principle, automatic alignment and correction can be achieved after each hydrogen fuel cell assembly is stacked, thus ensuring the neatness of the stacked hydrogen fuel cell assembly for subsequent pressing. The stacking operation is completed by stacking multiple hydrogen fuel cell assemblies until the lower end of the pallet 605 contacts the moving frame 5. At this time, the lower end of the top plate 710 is flush with the upper end of the pallet 605. The upper surface of the workbench 1 is symmetrically fixed with guide rails 101, and a fixed inclined block 102 is fixed on the workbench 1, with the upper end of the inclined surface of the fixed inclined block 102 located directly below the pressing mechanism 3; the pressing mechanism 3 includes a first cylinder 301 fixed on the gantry frame 2, and a fixed plate 302 is fixed to the output end of the first cylinder 301, and a first inclined plate 303 is fixed to the side of the fixed plate 302, with the inclined surface of the first inclined plate 303 having an inclination angle of 45°; the fixed plate 302 and the vertical rod 304 are slidably connected, and the lower end of the vertical rod 304 is fixed on the pressure plate 306, and a pressure sensor 305 is fixed on the pressure plate 306, with a first inclined plate 305 fixed between the pressure sensor 305 and the fixed plate 302. Spring 307; Slider 501 is symmetrically fixed on the lower end face of the movable frame 5, and slider 501 is slidably connected to guide rail 101; Positioning mechanism 8 includes a ring 801 disposed outside motor 601, and inclined plate 802 is fixed on ring 801, and inclined plate 802 is slidably connected to roller 705. At the same time, support rod 803 is fixed at the lower end of ring 801, and support rod 803 is slidably connected to movable frame 5. Base plate 804 is fixed at the lower end of support rod 803, and a fourth spring 805 is fixed between base plate 804 and movable frame 5. At the same time, a round shaft 806 is connected to the lower end face of base plate 804 by bearing, and round shaft 806 is slidably connected to fixed inclined block 102. After multiple hydrogen fuel cell components are stacked, such as Figures 1-7 As shown, multiple hydrogen fuel cell modules are stacked on the pallet 605. During pressing, the extension of the second cylinder 4 drives the support plate 502, the moving frame 5, the stacking mechanism 6, the stacked hydrogen fuel cell modules, the alignment mechanism 7, and the positioning mechanism 8 to move backward. Combined with the sliding action between the slider 501 and the guide rail 101, the stability of the device's movement is ensured. When the device moves backward, the circular shaft 806 rolls into contact with the inclined surface of the fixed inclined block 102. Further backward movement of the device allows the circular shaft 806 to be forced to drive the base plate 804, support rod 803, and other components. As the ring 801 and the inclined plate 802 move upward, when the inclined plate 802 contacts the roller 705, the roller 705 is driven by force to move the frame 704, the crossbar 706, the fixing frame 707 and the top plate 710. When the roller 806 rolls to the uppermost side of the inclined surface of the fixed inclined block 102, the rolling action between the roller 705 and the inclined plate 802 makes the top plate 710 contact the hydrogen fuel cell assembly stacked on the stacking mechanism 6, thereby achieving the limiting effect of the stacked hydrogen fuel cell assembly. At this time, the stacked hydrogen fuel cell assembly is located directly below the pressure plate 306. During the pressing process, the first cylinder 301 extends, causing the fixed plate 302, the first inclined plate 303, and the pressure plate 306 to move downwards. When the pressure plate 306 contacts the stacked hydrogen fuel cell assembly, the first inclined plate 303 contacts the round rod 714. Through the continuous extension of the first cylinder 301, the fixed plate 302 can move relative to the pressure plate 306. With the sliding guide effect between the fixed plate 302 and the vertical rod 304, the stability of the movement of the fixed plate 302 can be ensured. At this time, the first spring 307 is compressed. Through the elastic effect of the first spring 307, the pressure plate 306 can apply pressure to the stacked hydrogen fuel cell assembly, thereby realizing the pressing effect of the stacked hydrogen fuel cell assembly. The pressure sensor 305 can detect the pressure to ensure the normal progress of the pressing process. When the fixed plate 302 moves relative to the vertical rod 304, the first inclined plate 303 continues to move downward relative to the round rod 714. Combined with the rolling action between the round rod 714 and the first inclined plate 303, the mounting plate 713 is forced to move relative to the top plate 710. Combined with the sliding action between the mounting plate 713 and the round rod 711, the stability of the mounting plate 713's movement is ensured. At this time, the third spring 712 contracts under force. Through the elastic action of the third spring 712, the top plate 710 applies pressure to the sides of the stacked hydrogen fuel cell assembly. The force effectively ensures the limiting effect on the sides of the stacked hydrogen fuel cell components during the pressing process, thereby avoiding problems such as bulging deformation or misalignment between components during the pressing process, effectively ensuring production quality. Furthermore, since the inclination angle of the first inclined plate 303 is 45°, when the elastic coefficient and size of the third spring 712 and the first spring 307 are the same, it can be ensured that the downward pressing force and the side pressing force are equal, thus better meeting the actual use requirements.
