Description

Technical Field

[0001] The present invention belongs to the technical field of motor bipolar plate processing, and specifically relates to a battery bipolar plate processing device. Background Art

[0002] A fuel cell is an efficient and environmentally friendly power generation device. In a fuel cell, a bipolar plate is one of its core components, mainly performing multiple functions such as conducting electricity, conducting heat, distributing reaction gases, and supporting the battery structure. The performance and quality of the bipolar plate directly affect the overall performance of the fuel cell. Traditional fuel cell bipolar plate manufacturing processes include methods such as die pressing, laser cutting, and CNC machining. However, the aforementioned methods usually have problems such as long production cycles, high costs, and difficulty in achieving large-scale automated production.

[0003] Chinese Patent CN119388819A, announced on May 7, 2025, discloses a battery bipolar plate processing device. By setting a positioning mechanism between the thinning component and the embossing component, the problem of sheet offset during transmission in existing rolling equipment is effectively solved. In the positioning mechanism, the pushing member and the guiding portion can adjust and fix the position of the raw material, ensuring that the raw material is in an accurate position before entering the embossing component, avoiding offset phenomena, thereby improving the processing accuracy and production stability of the bipolar plate, ensuring that the flow channel embossing of each bipolar plate is consistent, and optimizing and improving the overall performance of the fuel cell. However, when thinning the sheet, the two ends of the sheet do not evenly extend outwards, resulting in unevenness at the two ends of the sheet, and thus the thinned sheet will have a phenomenon of thick edges and thin middle or cracking.

Detailed implementation manners

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a battery bipolar plate processing device, including a workbench 1, and a blanking groove 2 opened on the surface of the workbench 1. A sheet material master roll 3 is arranged on the top outer wall of the workbench 1, a feeding unit 4 is installed on the top outer wall of the workbench 1, and a plurality of pressing components 5 are arranged on the top outer wall of the workbench 1. The pressing component 5 includes a mounting frame 501 installed on the outer wall of the workbench 1. The mounting frames 501 are arranged at intervals in sequence along the conveying direction of the sheet material. A first pressing roller 503 and a second pressing roller 504 are installed on the outer wall of the mounting frame 501. A gap for the sheet material to pass through is provided between the first pressing roller 503 and the second pressing roller 504. A transmission block 6 is fixedly connected to one end outer wall of the second pressing roller 504. A plurality of edge trimming components 7 are arranged on the top outer wall of the workbench 1. The edge trimming component 7 includes a fixed block 701 installed on the outer wall of the workbench 1. The fixed blocks 701 are arranged at intervals in sequence along the conveying direction of the sheet material. A limiting plate 708 is fixedly connected to the outer wall of the fixed block 701. A driving rod 709 is fixedly connected to the outer wall of the limiting plate 708. A working box 705 is slidably connected to the outer wall of the driving rod 709. A turntable 710 adapted to the driving rod 709 is arranged on the outer wall of the working box 705. A cutting knife 712 is fixedly connected to the outer wall of the turntable 710. A linkage block 8 is fixedly connected to the outer wall of the driving rod 709. A transmission belt 9 adapted to the transmission block 6 is arranged on the outer wall of the linkage block 8.

[0027] During use, first pass the sheet on the master roll 3 of the sheet through the gap between the first pressure roller 503 and the second pressure roller 504 and enter the feeding unit 4. The gap sizes of multiple groups of the first pressure roller 503 and the second pressure roller 504 decrease successively along the conveying direction of the sheet, so that multiple groups of the first pressure roller 503 and the second pressure roller 504 can thin the sheet multiple times. Then connect the external power supply to start, and the feeding unit 4 conveys the sheet. At the same time, start the first pressure roller 503 and the second pressure roller 504 on the mounting frame 501 to extrude the sheet. The sheet will extend towards both ends under extrusion. At this time, the rotation of the second pressure roller 504 drives the transmission block 6 to rotate. The transmission block 6 drives the transmission belt 9 to rotate synchronously through the linkage block 8, thereby driving the driving rod 709 to rotate on the surface of the limiting plate 708. When the driving rod 709 rotates, it drives the turntable 710 to rotate on the surface of the working box 705, so as to drive the cutting knife 712 to trim both sides of the sheet, ensuring the flatness of both ends of the sheet. The cut-off scraps will fall into the inside of the blanking chute 2 and slide down through the slope at the bottom of the blanking chute 2, facilitating the collection of the scraps of the sheet.

[0028] Please refer to Figure 3 As shown in Figure 3 , the pressure component 5 further includes a driving motor 502 installed on the outer wall of the workbench 1 and adapted to the first pressure roller 503. A connecting gear 505 is fixedly connected to the outer wall of one end of the first pressure roller 503. A fixed gear 506 adapted to the connecting gear 505 is arranged on the outer wall of the mounting frame 501. A connecting plate 507 is rotatably connected to the outer wall of the fixed gear 506. A transmission gear 508 adapted to the fixed gear 506 is arranged on the outer wall of the connecting plate 507. A linkage plate 509 is rotatably connected to the outer wall of one end of the connecting plate 507, and one end of the linkage plate 509 is rotatably connected to the second pressure roller 504. A linkage gear 510 adapted to the transmission gear 508 is arranged on the outer wall of one end of the second pressure roller 504. A hydraulic cylinder 511 adapted to the second pressure roller 504 is arranged on the inner wall of the mounting frame 501.

[0029] During use, first start the hydraulic cylinder 511 to push the second pressure roller 504 to slide on the surface of the mounting frame 501, thereby adjusting the gap size between the first pressure roller 503 and the second pressure roller 504. During this process, the second pressure roller 504 will push the connecting plate 507 to rotate through the linkage plate 509, thereby adjusting the position of the transmission gear 508, ensuring the meshing relationship among the fixed gear 506, the transmission gear 508 and the linkage gear 510. No matter where the second pressure roller 504 is located, when the driving motor 502 is started to drive the first pressure roller 503 to rotate, it will drive the fixed gear 506 to rotate synchronously through the connecting gear 505, and through the meshing among the fixed gear 506, the transmission gear 508 and the linkage gear 510, thereby driving the second pressure roller 504 to rotate synchronously with the first pressure roller 503.

[0030] Please refer to Figure 4 and Figure 5 , the trimming component 7 further includes a connecting rod 702 and a deburring mechanism mounted on the outer wall of the fixed block 701. A transmission rod 703 is rotatably connected to the outer wall of the fixed block 701. Threaded grooves 704 adapted to the work box 705 are provided at both ends of the transmission rod 703, and the grooving directions of the threaded grooves 704 at both ends are opposite. A hand wheel 706 is fixedly connected to the outer wall of one end of the transmission rod 703. A support block 711 adapted to the cutting knife 712 is provided on the outer wall of the work box 705, and there is a blanking gap between the support block 711 and the turntable 710. A baffle 707 is fixedly connected to the outer wall of the work box 705.

[0031] During use, first drive the transmission rod 703 to rotate through the hand wheel 706, and drive the two work boxes 705 to move towards the center of the plate through the threaded grooves 704 at both ends of the transmission rod 703. During this process, the connecting rod 702 will limit the work box 705 to ensure the stability of the work box 705 during movement and work. When the turntable 710 rotates, the cutting part of the plate is supported by the support block 711, so that the cutting knife 712 prevents the cutting part of the plate from deforming during cutting, thereby ensuring the cutting efficiency of the plate. The cut-off scraps fall onto the surface of the baffle 707 through the blanking gap between the support block 711 and the turntable 710, and then fall into the blanking groove 2 through the inclined surface of the baffle 707.

[0032] Please refer to Figures 6 - 8 , the deburring mechanism includes a grinding block 713 mounted on the outer wall of the turntable 710. Suction ports 714 are equidistantly arranged along the circumferential direction on the outer wall of the turntable 710. An air inlet 715 adapted to the suction port 714 is provided on the outer wall of the work box 705. An air inlet pipe 716 adapted to the air inlet 715 is provided on the inner wall of the work box 705. The air inlet pipe 716 includes an air inlet pipe body 7161. A first air outlet 7162 and a second air outlet 7163 are provided on the outer wall of one end of the air inlet pipe body 7161. A partition plate 720 adapted to the air inlet pipe 716 is provided on the inner wall of the work box 705, and the inner part of the work box 705 is separated into a first air suction chamber 721 and a second air suction chamber 722 through the partition plate 720. A dust suction structure is provided on the inner wall of the work box 705.

[0033] During use, when the turntable 710 rotates to cut the sheet, the grinding block 713 will grind the cutting part of the sheet. The metal dust generated by grinding will be sucked into the inside of the air inlet pipe 716 from the air suction port 714 and the air inlet 715 through the dust suction structure. After the metal dust is sucked into the inside of the air inlet pipe body 7161, it will enter the inside of the working box 705. The inside of the working box 705 is separated into a first air suction chamber 721 and a second air suction chamber 722 by a partition plate 720. Therefore, the metal dust can be discharged into the inside of the first air suction chamber 721 through the first air outlet 7162 or into the inside of the second air suction chamber 722 through the second air outlet 7163.

[0034] Please refer to Figure 7 , Figure 9 and Figure 10 , the dust suction structure includes a limiting rod 717 installed on the inner wall of the working box 705. A limiting ring 718 is fixedly connected to the outer wall of one end of the limiting rod 717. A semi-gear 719 adapted to the limiting ring 718 is provided on the outer wall of the driving rod 709. A first piston plate 723 is slidably connected to the inner wall of the first air suction chamber 721. A first spring 724 adapted to the first piston plate 723 is provided on the inner wall of the first air suction chamber 721. A rack 725 adapted to the semi-gear 719 is provided on the outer wall of the first piston plate 723. A first spring piece 726 is fixedly connected to the inner wall of the first air suction chamber 721. A first plugging plate 727 adapted to the first air outlet 7162 is provided on the outer wall of the first spring piece 726. A second piston plate 728 is slidably connected to the inner wall of the second air suction chamber 722. A second spring 729 adapted to the second piston plate 728 is provided on the inner wall of the second air suction chamber 722. A nylon rope 730 adapted to the first piston plate 723 is provided on the outer wall of the second piston plate 728. A guide wheel 731 adapted to the nylon rope 730 is provided on the outer wall of the partition plate 720. A second spring piece 732 is fixedly connected to the inner wall of the second air suction chamber 722. A second plugging plate 733 adapted to the second air outlet 7163 is provided on the outer wall of the second spring piece 732. An exhaust port 734 adapted to the first air suction chamber 721 and the second air suction chamber 722 is provided on the outer wall of the working box 705. A filter screen 735 is provided on the inner wall of the exhaust port 734. A third spring piece 736 is fixedly connected to the outer wall of the working box 705. A third plugging plate 737 adapted to the exhaust port 734 is provided on the outer wall of the third spring piece 736.

[0035] During use, when the working box 705 moves on the surface of the connecting rod 702, it will push the limit ring 718 to move synchronously through the limit rod 717, thereby pushing the half gear 719 to slide on the surface of the driving rod 709, further ensuring the meshing between the half gear 719 and the rack 725. When the driving rod 709 rotates, it will drive the half gear 719 to rotate synchronously, and push the rack 725 to move upward through the meshing of the half gear 719 and the rack 725, so that the rack 725 pulls the first piston plate 723 to slide upward inside the first air suction chamber 721 and stretch the first spring 724. When the first piston plate 723 slides upward, it will cause a suction force in the first air suction chamber 721, and pull the first blocking plate 727 to rotate around the connection point of the first spring piece 726 and the partition plate 720 through the suction force, thereby releasing the limit on the first air outlet 7162, so that the metal dust enters the inside of the first air suction chamber 721 through the first air outlet 7162. When the rack 725 and the half gear 719 are in thrust meshing, the first spring 724 pulls the first piston plate 723 to reset under the action of force. During this process, the first piston plate 723 will pull the second piston plate 728 to slide inside the second air suction chamber 722 and stretch the second spring 729 through the nylon rope 730. When the second piston plate 728 slides upward, it will cause a suction force in the second air suction chamber 722, and pull the second blocking plate 733 to rotate around the connection point of the second spring piece 732 and the partition plate 720 through the suction force, thereby releasing the limit on the second air outlet 7163, so that the metal dust enters the inside of the second air suction chamber 722 through the second air outlet 7163. The guide wheel 731 can guide the nylon rope 730. When the first spring 724 and the second spring 729 pull the first piston plate 723 and the second piston plate 728 to reset under the action of force, the air inside the first air suction chamber 721 and the second air suction chamber 722 is squeezed and then passes through the filter screen 735 into the exhaust port 734, and pushes the third blocking plate 737 to rotate around the connection point of the third spring piece 736 and the working box 705, thereby releasing the limit on the exhaust port 734, so that the air can be discharged from the exhaust port 734.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
