[0027] Please see Figures 1 to 5 The present invention provides a technical solution: a power-type long-life battery positive electrode lead paste assembly structure, including an equipment box 1, a support platform 2, a conveying component, a paste application component, and a curing component.

[0028] The equipment box 1 contains a fixed control board, which is connected to the conveying component, the coating component, and the curing component. The control board controls the start and stop operations of these components. The control board may be, but is not limited to, a programmable logic controller (PLC) or an industrial computer.

[0029] Equipment box 1 is fixedly installed below support platform 2. The conveying component is installed on support platform 2, and the paste application component and curing component are also installed on support platform 2. The paste application component and the fixing component are both mounted above the conveying component. The function of support platform 2 is to support the conveying component, paste application component, and curing component, providing a stable support platform for the entire equipment to ensure the reliability and safety of the equipment during operation.

[0030] The coating assembly includes a support assembly, a mixing assembly, multiple feeding assemblies, and multiple coating rollers 7. The mixing assembly and each feeding assembly are mounted on the support assembly. The support assembly includes a support plate 9 and multiple support columns 8. The lower end of the support column 8 is fixedly connected to the support platform 2, and the upper end of the support column 8 is fixedly installed to the support plate 9.

[0031] The support components are used to support and fix the mixing components and each feeding component.

[0032] The stirring assembly includes a tank 10, a cover plate 11, a second servo motor 12, and a rotating rod 19. The tank 10 is fixedly mounted on top of a support plate 9. The cover plate 11 is detachably mounted on the tank 10. The second servo motor 12 is fixedly mounted on the cover plate 11. One end of the rotating rod 19 passes through the cover plate 11 and the two are rotatably connected. The output shaft of the second servo motor 12 is drively connected to the rotating rod 19. Multiple stirring rods 20 are fixedly connected to the outer wall of the rotating rod 19. Multiple feed pipes 13 are fixedly mounted on the cover plate 11, and the feed pipes 13 communicate with the interior of the tank 10.

[0033] The feed pipe 13 is used to transport the materials (including liquid and solid materials) for preparing lead paste, allowing the materials to enter the tank 10. After the second servo motor 12 is started, the output shaft of the second servo motor 12 drives the rotating rod 19 to rotate, and the rotating rod 19 drives each stirring rod 20 to rotate, and each stirring rod 20 stirs and mixes the materials in the tank 10.

[0034] The feeding assembly includes a conveying pump 14 and a feeding nozzle 17. The conveying pump 14 is fixedly mounted on the support plate 9. The medium inflow end of the conveying pump 14 is fixedly mounted to the tank 10 and the two are connected. The medium outflow end of the conveying pump 14 is fixedly mounted to the feeding nozzle 17 and the two are connected. Each coating roller 7 is rotatably mounted on the conveying component.

[0035] The transfer pump 14 includes, but is not limited to, a media pump or a gear pump. The transfer pump 14 draws lead paste from the tank 10 and delivers it to the discharge nozzle 17, through which the lead paste falls onto the positive electrode plate 24. The discharge nozzle 17 includes, but is not limited to, a filling nozzle.

[0036] During the conveying process of the positive electrode plate 24, the feeding component applies lead paste to the positive electrode plate 24, the coating roller 7 spreads the lead paste evenly on the positive electrode plate 24, and the curing component dries and cures the lead paste on the positive electrode plate 24.

[0037] The mixing component is used to thoroughly mix the lead paste inside the tank 10, ensuring its uniformity. The dispensing component conveys the mixed lead paste from the tank 10 and evenly coats it onto the positive electrode plate 24 through the dispensing nozzle 17. The coating roller 7 is rotatably mounted on the square tube 5 of the conveying component and is located above the conveyor belt 4. The first servo motor 6 is connected to the coating roller 7 for transmission. The coating roller 7's function is to evenly spread the lead paste on the positive electrode plate 24, ensuring uniform coating thickness. The curing component's main function is to dry and cure the lead paste applied to the positive electrode plate 24.

[0038] Specifically, the conveying components include a first servo motor 6, a conveyor belt 4, at least two rotating rollers, and at least two square tubes 5. Both square tubes 5 are fixedly mounted on the support platform 2, and are parallel to each other. The two ends of each rotating roller are rotatably connected to the two square tubes 5, and are parallel to each other. The conveyor belt 4 is wound around the outer walls of the two rotating rollers with the largest spacing. The first servo motor 6 is fixedly mounted on one of the square tubes 5 and is driven by each rotating roller. A chain drive is used between the first servo motor 6 and each rotating roller. A coating roller 7 is rotatably mounted on the square tube 5 and is located above the conveyor belt 4. The first servo motor 6 is driven by the coating roller 7.

[0039] The main function of the conveying component is to transport the positive electrode plate 24, allowing it to pass through processes such as coating and curing. After the first servo motor 6 starts, it drives each rotating roller to rotate, which in turn drives the conveyor belt 4 to rotate, causing the positive electrode plate 24 above it to move. Simultaneously, the first servo motor 6 drives the coating roller 7 to rotate, which presses the lead paste on the positive electrode plate 24 to make the lead paste more uniform and ensure the uniformity of the coating thickness.

[0040] Specifically, the feeding assembly also includes a feeding cylinder 15, a feeding pipe 16, and a crossbar 18. The feeding cylinder 15 is fixedly installed on the support plate 9. The medium outlet end of the conveying pump 14 is fixedly installed and connected to the feeding cylinder 15. The upper end of the feeding pipe 16 is fixedly installed and connected to the feeding cylinder 15. The lower end of the feeding pipe 16 is fixedly installed and connected to the feeding nozzle 17. The two ends of the crossbar 18 are fixedly connected to (or detachably installed on) two support columns 8 respectively. The feeding nozzle 17 is installed on the crossbar 18.

[0041] The pump 14 draws lead paste from the tank 10, and the lead paste flows sequentially through the discharge cylinder 15, discharge pipe 16, and discharge nozzle 17 before exiting. A crossbar 18 supports the discharge nozzle 17; adjusting the height of the crossbar 18 allows for adjustment of the height of the discharge nozzle 17.

[0042] Specifically, the curing components include a curing chamber 3, a fan 22, and a steam pipe array 23. The curing chamber 3 is fixedly installed on the support platform 2 and is positioned above the conveying components. The steam pipe array 23 is fixedly installed on the lower inner wall of the curing chamber 3 and is located above the conveyor belt 4. The fan 22 is fixedly installed on the upper inner wall of the curing chamber 3, with the airflow outlet of the fan 22 facing the steam pipe array 23. An air inlet 21 is provided on the top wall of the curing chamber 3.

[0043] In actual implementation, a steam generator produces steam, which is then channeled into the steam pipe array 23. The steam pipe array 23 heats up, thereby heating the interior of the curing chamber 3. After the fan 22 starts, it blows hot air towards the positive electrode plate 24 and the lead paste, drying the lead paste and curing it onto the positive electrode plate 24. Through the action of the fan 22 and the steam pipe array 23, the curing components provide suitable curing conditions for the lead paste, promoting the formation and stability of lead dioxide, thereby improving battery performance.

[0044] The control board is electrically connected to the first servo motor 6, the second servo motor 12, each delivery pump 14, the fan 22, and the steam generator. The control board controls the start and stop of the first servo motor 6, the second servo motor 12, each delivery pump 14, the fan 22, the steam generator, etc., to meet the needs of automated control.

[0045] In use, the positive electrode plate 24 is first conveyed to the bottom of the paste-coating component via a conveying component. The stirring assembly in the paste-coating component then operates; the second servo motor 12 drives the rotating rod 19 to rotate, which in turn drives the stirring rod 20 to thoroughly stir the lead paste, ensuring its uniformity. The stirred lead paste is then pumped from the tank 10 by the delivery pump 14 and evenly applied to the positive electrode plate 24 through the discharge nozzle 17. The coating roller 7 smooths the lead paste on the positive electrode plate 24, ensuring uniform coating thickness. Subsequently, the positive electrode plate 24 enters the curing component, where the fan 22 and steam pipe 23 operate to provide suitable curing conditions for the lead paste, promoting the formation and stabilization of lead dioxide. After curing, the positive electrode plate 24 completes the assembly process, thus achieving a highly efficient and precise assembly of positive electrode lead paste for power-type long-life batteries.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
