Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cell manufacturing and processing technology, and in particular to a processing equipment and processing method for manufacturing hydrogen fuel cells. Background Technology

[0002] A fuel cell is a power generation device that directly converts chemical energy into electrical energy. Its principle is to provide power to a car through the chemical reaction of hydrogen and oxygen, and ultimately produce water vapor that is emitted into the external environment. This device has many advantages, such as low pollution, low noise, and high efficiency. The core components of a hydrogen fuel cell include bipolar plates, proton exchange membranes, catalyst layers, and gas diffusion layers. Bipolar plates are generally rigid sheets, while proton exchange membranes are usually flexible sheets. The proton exchange membrane can conduct protons and prevent electrons from passing through. The catalyst layer accelerates the reaction rate of hydrogen decomposition and oxygen reduction, and the gas diffusion layer ensures that the gas can be evenly distributed on the catalyst layer. In recent years, as hydrogen fuel cells have developed towards higher voltage and higher power, it has become necessary to increase the number of bipolar plates in hydrogen fuel cells to improve the overall voltage and achieve higher power output. Current stacking technology involves stacking the plates one by one from bottom to top, and then pressing them together using a press on a stacking machine. However, increasing the number of plates inevitably leads to an increase in height, making it difficult to ensure that each layer of upper electrode plates is neatly placed, and causing misalignment in the fuel cell. Chinese patent application CN111613804A discloses a fuel cell processing device. However, when stacking fuel cells, the proton exchange membrane between the bipolar plates is a flexible membrane. Therefore, during the stacking process, the proton exchange membrane is prone to bending or curling, making accurate positioning impossible and hindering subsequent processing. This affects production efficiency in actual production. Therefore, this invention proposes a processing device and method for hydrogen fuel cell manufacturing to solve the problems existing in the prior art. Summary of the Invention

This processing equipment utilizes a base plate, a pressing worktable, a stacking mechanism, a hard sheet feeding mechanism, a flexible sheet feeding mechanism, a second hydraulic cylinder, and a push plate to automatically stack and press the battery cells, significantly increasing the processing speed of hydrogen fuel cells. Simultaneously, the device incorporates a stacking frame, an adjustment mechanism, a bottom support bar, a limiting plate, an inclined sliding surface, and suction holes to ensure accurate positioning of the stacked cells during the stacking process, preventing bending of the flexible sheets and guaranteeing the stacking effect of the device.

[0004] To achieve the purpose of this invention, the invention is implemented through the following technical solution: a processing equipment for manufacturing hydrogen fuel cells, including a base plate, a pressing worktable and a control panel, wherein a stacking structure is provided on the base plate directly below the pressing end of the pressing worktable, and a hard sheet feeding mechanism and a flexible sheet feeding mechanism are respectively provided on the left and right sides of the stacking mechanism. The stacking mechanism includes a stacking frame, an adjustment mechanism, a bottom support strip, a limiting plate, and an inclined sliding surface. The stacking frame is rectangular. The bottom plate is provided with an adjustment mechanism that drives the stacking frame to rise and fall. Each of the four sides of the stacking frame is provided with a slidingly mounted bottom support strip. The bottom surface of the bottom support strip is flush with the bottom surface of the stacking frame. A limiting plate is provided above the bottom support strip. An inclined sliding surface is provided at the inner end of the bottom support strip. Multiple suction holes are provided at the top of the bottom support strip. A sensor is provided on the bottom surface of the bottom support strip. The stacking frame has mounting grooves on its four outer sides near the bottom support bar. A first drive mechanism that drives the bottom support bar to move is fixed in the mounting groove. The first drive mechanism is also equipped with a second drive mechanism that drives the limiting plate to move.

[0005] A further improvement is that the first drive mechanism includes a first electric telescopic rod and a fixing plate. The first electric telescopic rod is fixed in the mounting groove, and the output end of the first electric telescopic rod is fixed with the fixing plate. The fixing plate is fixedly connected to the top surface of the outer end of the bottom support bar.

[0006] A further improvement is that the second driving mechanism includes a second electric telescopic rod, a movable plate, and a guide rod. One end of the second electric telescopic rod is fixedly connected to a fixed plate. The output end of the second electric telescopic rod is fixed with a movable plate. The movable plate is provided with a groove that matches the first electric telescopic rod. A guide rod is fixed between the movable plate and the limiting plate. The guide rod passes through the stacking frame and is slidably connected to the stacking frame. The movable plate is embedded in the mounting groove.

[0007] Further improvements include: the adjustment mechanism includes a threaded drive rod and a limiting rod; mounting seats are provided on both the left and right sides of the stacking frame; each mounting seat includes a threaded seat and a guide seat; the threaded seat and the guide seat are symmetrically arranged; the threaded seat is threadedly connected to the threaded drive rod; the guide seat is slidably connected to the limiting rod; both sets of threaded seats and guide seats are diagonally distributed; and baffles are provided on the top of both the threaded drive rod and the limiting rod.

[0008] Further improvements are made in that: the rigid sheet feeding mechanism and the flexible sheet feeding mechanism have the same structure, both including a bottom rotating platform, a robotic arm and a feeding seat. The bottom rotating platform is fixedly connected to the base plate, the robotic arm is rotatably mounted on the bottom rotating platform, and the feeding seat is detachably mounted on the robotic arm.

[0009] A further improvement is that the feeding seat includes a mounting block, a bidirectional electric telescopic rod, an adsorption seat, and a limiting frame. The mounting block is detachably connected to the robotic arm. A limiting frame is provided on the outer side of the lower end of the mounting block. The bidirectional electric telescopic rod is symmetrically provided at the lower end of the mounting block. Adsorption seats are fixed at both ends of the bidirectional electric telescopic rod. The adsorption seats are located inside the limiting frame and are slidably connected to the limiting frame.

[0010] A further improvement is that the pressing worktable includes a support column, a top plate, a first hydraulic cylinder, and a pressure plate. The support column is fixedly connected to the bottom plate, and the top plate is fixed to the top of the support column. The first hydraulic cylinder is located on the top plate at a position directly above the stacking frame, and the pressure plate is fixed to the output end of the first hydraulic cylinder.

[0012] The processing method for the aforementioned hydrogen fuel cell manufacturing and processing equipment includes the following steps: S1. First, the stacking frame is moved by the adjustment mechanism, thereby moving the stacking frame to the appropriate position; S2. Then, according to the stacking requirements, the flexible parts and rigid parts are alternately placed in the stacking frame by the rigid sheet feeding mechanism and the flexible sheet feeding mechanism, respectively, while the stacking frame supports a certain number of flexible parts and rigid parts. S3. At the same time, the stacking frame moves the fixed plate and the bottom support bar inward through the first electric telescopic rod, so that the bottom support bar can support the rigid or flexible sheets of different sizes. Meanwhile, the second electric telescopic rod pushes the moving plate, which in turn pushes the limiting plate to move through the guide rod, thereby limiting the flexible and rigid parts of different sizes from the side. S4. After a certain number of stacks are completed, the stacking frame is moved down by the adjustment mechanism and close to the bottom plate. The fixed plate and the bottom support bar are moved outward synchronously by the first electric telescopic rod. As the support bar moves outward, the hard and soft sheets stacked in the stacking frame slowly slide down to the bottom plate through the inclined sliding surface. Then the stacking frame is dropped and the stacking and unloading work is repeated. S5. After stacking is completed, the bottom support bar moves outward to the appropriate position, while the stacking frame moves to the top. At the same time, the loading seats on the rigid sheet loading mechanism and the flexible sheet loading mechanism rotate outward. At this time, the pressure plate is pushed by the first hydraulic cylinder to press the stacked flexible sheet and rigid sheet together, and the battery is fastened by screws through the fastening holes on the battery. S6. After pressing, the second hydraulic cylinder pushes the push plate to push out the fastened battery stack.

[0015] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0016] according to Figures 1-6As shown, this embodiment proposes a processing equipment for manufacturing hydrogen fuel cells, including a base plate 1, a pressing worktable and a control panel. The base plate 1 is provided with a stacking structure directly below the pressing end of the pressing worktable. The left and right sides of the stacking mechanism are respectively provided with a hard sheet feeding mechanism and a flexible sheet feeding mechanism. The device is automatically controlled via the control panel on the base plate 1. The base plate 1 is used for placing hydrogen fuel cell materials, while the pressing worktable is used for pressing the materials together. The device is equipped with a rigid sheet feeding mechanism and a flexible sheet feeding mechanism. The rigid sheet feeding mechanism is used for feeding rigid materials, such as bipolar plates, while the flexible sheet feeding mechanism is used for feeding flexible materials, such as exchange membranes. The device is also equipped with a stacking mechanism for automatic stacking of rigid and flexible sheets, which greatly increases the overall automation of the device. The stacking mechanism includes a stacking frame 2, an adjustment mechanism, a bottom support bar 3, a limiting plate 4, and an inclined sliding surface 5. The stacking frame 2 is rectangular. The base plate 1 is provided with an adjustment mechanism that drives the stacking frame 2 to rise and fall. The four sides of the stacking frame 2 are provided with slidingly installed bottom support bars 3. The bottom surface of the bottom support bar 3 is flush with the bottom surface of the stacking frame 2. The bottom support bar 3 is provided with a limiting plate 4 above it. The inner end of the bottom support bar 3 is provided with an inclined sliding surface 5. The top of the bottom support bar 3 is provided with multiple sets of suction holes 6. The bottom surface of the bottom support bar 3 is provided with a sensor 7. In this device, the stacking frame 2 is used for stacking bipolar plates and exchange membranes. A bottom support bar 3 is installed at the bottom of the stacking frame 2 to support materials of different sizes. A limiting plate 4 is also installed to limit the size of materials from the side, ensuring neat stacking and preventing misalignment. During stacking, when the size of the bipolar plate and the exchange membrane are the same, partial stacking can be performed within the stacking frame 2. When the size of the bipolar plate and the exchange membrane are different, stacking is not performed in the stacking frame 2; each plate is placed individually. The end of the bottom support bar 3 is equipped with an inclined sliding surface 5. The outward movement of the flexible or rigid sheet, along with the sliding surface, further ensures the neatness of the stacked rigid and flexible sheets. During the stacking process, after the bottom support bar 3 has placed the rigid or flexible sheet, the stacking frame 2 is moved downward by adjusting the structure, causing the bottom support bar 3 to press on the stacked material sheets, thereby initially compressing the air between the flexible and rigid sheets, further increasing the stacking effect of the device. At the same time, the device is equipped with suction holes 6 on the bottom support bar 3 to further prevent the flexible sheet from bending or curling when placing it. The sensor ensures the accuracy of the bottom support bar 3's reset after each placement, thereby increasing the stacking effect of the device. The stacking frame 2 has mounting grooves 8 on its four outer sides near the bottom support bar 3. A first driving mechanism that drives the bottom support bar 3 to move is fixed in the mounting groove 8. The first driving mechanism is also equipped with a second driving mechanism that drives the limiting plate 4 to move.

[0017] The first drive mechanism includes a first electric telescopic rod 9 and a fixing plate 10. The first electric telescopic rod 9 is fixed in the mounting groove 8. The output end of the first electric telescopic rod 9 is fixed with the fixing plate 10. The fixing plate 10 is fixedly connected to the top surface of the outer end of the bottom support bar 3.

[0018] The first electric telescopic rod 9 pushes the fixed plate 10 to move, thereby driving the bottom support bar 3 to move, and thus adjusting the position of the bottom support bar 3.

[0019] The second driving mechanism includes a second electric telescopic rod 11, a movable plate 12, and a guide rod 13. One end of the second electric telescopic rod 11 is fixedly connected to the fixed plate 10. The output end of the second electric telescopic rod 11 is fixed with the movable plate 12. The movable plate 12 is provided with a groove 14 that is adapted to the first electric telescopic rod 9. The guide rod 13 is fixed between the movable plate 12 and the limiting plate 4. The guide rod 13 passes through the stacking frame 2 and is slidably connected to the stacking frame 2. The movable plate 12 is embedded in the mounting groove 8.

[0020] The second electric telescopic rod 11 pushes the moving plate 12 to move, and the guide rod 13 pushes the limiting plate 4 to move, thereby adjusting the position of the limiting plate 4.

[0021] The adjustment mechanism includes a threaded drive rod 15 and a limiting rod 16. Mounting seats are provided on both the left and right sides of the stacking frame 2. Each mounting seat includes a threaded seat 17 and a guide seat 18. The threaded seat 17 and the guide seat 18 are symmetrically arranged. The threaded seat 17 is threadedly connected to the threaded drive rod 15, and the guide seat 18 is slidably connected to the limiting rod 16. Both sets of threaded seats 17 and guide seats 18 are diagonally distributed. A baffle 19 is provided on the top of both the threaded drive rod 15 and the limiting rod 16.

[0022] Two sets of threaded drive rods 15 are provided and are driven by a motor to rotate synchronously. The rotation of the threaded drive rods 15 drives the stacking frame 2 to move up and down, thereby performing stacking work. At the same time, the limiting rods 16 limit the movement of the stacking frame 2 to ensure the stability of the movement of the stacking frame 2. The diagonal installation method can further ensure the stability of the movement of the stacking frame 2.

[0023] The rigid sheet feeding mechanism and the flexible sheet feeding mechanism have the same structure, both including a bottom rotating platform 20, a robotic arm 21 and a feeding seat. The bottom rotating platform 20 is fixedly connected to the base plate 1. The robotic arm 21 is rotatably mounted on the bottom rotating platform 20, and the feeding seat is detachably mounted on the robotic arm 21.

[0024] The loading base includes a mounting block 22, a bidirectional electric telescopic rod 23, an adsorption seat 24, and a limiting frame 25. The mounting block 22 is detachably connected to the robotic arm 21. A limiting frame 25 is provided on the outer side of the lower end of the mounting block 22. The bidirectional electric telescopic rod 23 is symmetrically provided on the lower end of the mounting block 22. Adsorption seats 24 are fixed at both ends of the bidirectional electric telescopic rod 23. The adsorption seats 24 are located inside the limiting frame 25 and are slidably connected to the limiting frame 25.

[0025] The rotating table can drive the robotic arm 21 to rotate, enabling the device to automatically perform stacking work. The robotic arm 21 is a multi-axis robotic arm, and its end is equipped with a detachable loading seat, which allows it to be used flexibly. The loading seat is equipped with a mounting block 22 for installation and removal, while the bidirectional electric telescopic rod 23 is used to drive the adsorption seat 24 to move, thereby picking up and stacking materials of different sizes. The limiting frame 25 is set to ensure the stability of the movement of the adsorption seat 24.

[0026] The pressing workbench includes a support column 26, a top plate 27, a first hydraulic cylinder 28, and a pressure plate 29. The support column 26 is fixedly connected to the base plate 1. The top plate 27 is fixed to the top of the support column 26. The first hydraulic cylinder 28 is located on the top plate 27 at a position directly above the stacking frame 2. The pressure plate 29 is fixed to the output end of the first hydraulic cylinder 28.

[0027] By activating the first hydraulic cylinder 28, the pressure plate 29 is pushed down, thereby pressing the electromagnetic laminations together.

[0028] The inner side of the support column 26 is provided with a push plate 30, and the support column 26 is provided with a second hydraulic cylinder 31 that pushes the push plate 30 to move. The outer side of the support column 26 is provided with an L-shaped frame 32 for fixing the second hydraulic cylinder 31. The L-shaped frame 32 is fixedly connected to the base plate 1, and the bottom of the push plate 30 is slidably connected to the top surface of the top plate 27.

[0029] By activating the second hydraulic cylinder 31, the push plate 30 is pushed out to push out the tightly pressed battery stack, facilitating subsequent work.

[0030] The processing method for hydrogen fuel cell manufacturing equipment described above includes the following steps: S1. First, the stacking frame 2 is moved by the adjustment mechanism, thereby moving the stacking frame to the appropriate position; S2. Then, according to the stacking requirements, the flexible parts and rigid parts are alternately placed in the stacking frame 2 by the rigid sheet feeding mechanism and the flexible sheet feeding mechanism respectively, while the stacking frame 2 supports a certain number of flexible parts and rigid parts. S3. At the same time, the stacking frame 2 drives the fixing plate 10 and the bottom support bar 3 to move inward through the first electric telescopic rod 9, so that the bottom support bar 3 can support the rigid or flexible sheets of different sizes. Meanwhile, the second electric telescopic rod 11 pushes the moving plate 12, which in turn pushes the limiting plate 4 to move through the guide rod 13, thereby limiting the flexible and rigid parts of different sizes from the side. S4. After a certain number of stacks are completed, the stacking frame 2 is moved down by the adjustment mechanism and close to the bottom plate 1. The first electric telescopic rod 9 drives the fixed plate 10 and the bottom support bar 3 to move outward synchronously. As the support bar moves outward, the hard and soft sheets stacked in the stacking frame 2 slowly slide down to the bottom plate 1 through the inclined sliding surface 5. Then the stacking frame is dropped and the stacking and unloading work is repeated. S5. After stacking is completed, the bottom support bar 3 moves outward to a suitable position, while the stacking frame 2 moves to the top. At the same time, the loading seats on the hard sheet loading mechanism and the flexible sheet loading mechanism rotate outward. At this time, the first hydraulic cylinder 28 pushes the pressure plate 29 to press the stacked flexible sheet and hard sheet together, and the battery is fastened with screws through the fastening holes on the battery. S6. After pressing, the second hydraulic cylinder 31 pushes the push plate 30 to push out the fastened battery stack.
