Description

Technical Field

[0001] This utility model relates to the field of vehicle processing technology, specifically to a battery cell assembly structure for special vehicles. Background Art

[0002] The assembly of vehicle battery cells involves precision processes. First, positive and negative electrode materials, separators, and electrolytes are prepared. Next, the positive and negative electrode materials are coated onto metal foil, dried, and then cut. Subsequently, the positive and negative electrode sheets are stacked or wound, and electrolyte is injected. Pouch cells are encapsulated in flexible packaging materials, while rigid-shell cells are placed in a metal casing and sealed. During initialization, the cells undergo an initial charge-discharge activation. Afterward, multiple cells are connected in a specific manner to form modules and integrated into a battery pack with a cooling system and a battery management system. Finally, comprehensive functional and safety testing is conducted. This process ensures the safety and performance of the battery pack.

[0003] In the assembly process of battery cells, electrode fabrication is extremely important, as its quality affects the subsequent quality of the battery cell. Typically, battery cell fabrication involves preparing a slurry using active materials and uniformly coating it onto a metal foil. After coating, a drying process is performed to remove the solvent, leaving pure electrode material. However, the current method of preparing the slurry by coating the metal foil with active materials usually involves manual application, resulting in uneven slurry distribution and difficulty in controlling the material thickness on the metal foil surface, thus affecting the quality of the assembled battery cell. Utility Model Content

[0004] The purpose of this invention is to provide a battery cell assembly structure for special vehicles to solve the problems described in the background art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A battery cell assembly structure for special vehicles includes a smooth plate with multiple support columns at its bottom. A first horizontal plate is positioned between two adjacent support columns, and a drive motor is fixedly mounted on the first horizontal plate. The output end of the drive motor is connected to a lead screw, and the other end of the lead screw is rotatably connected to a second horizontal plate on the other side. A press is slidably connected to the top surface of the smooth plate, and the output end of the press passes through the smooth plate and is connected to an infusion tank. A nozzle is located at the bottom of the infusion tank, which is fitted onto the outer circumference of the lead screw. The infusion tank slides back and forth in the transverse direction of the lead screw. A placement plate is positioned between the support columns, and the placement plate is in contact with the nozzle.

[0007] A further technical solution is that the smooth plate is provided with a sliding strip hole, and the bottom of the press is provided with a slide rod, which is slidably connected to the inner side wall of the sliding strip hole.

[0008] A further technical solution is that the press is a pneumatic motor.

[0009] A further technical solution is that the nozzle has a limiting strip hole at its bottom, and the limiting strip hole is connected to the infusion tank.

[0010] A further technical solution is that the placement plate is hollow, a compressor is installed inside the hollow, the output end of the compressor is connected to multiple vent pipes, the top surface of the placement plate is provided with multiple vent holes, and the multiple vent pipes are respectively connected to the vent holes.

[0011] A further technical solution is that the support column is equipped with a lifting component that connects to both sides of the placement plate.

[0012] A further technical solution is that the lifting assembly includes a first worm gear, a first fixed wheel, a second worm gear, and a second fixed wheel. Lifting blocks are provided on both sides of the placement plate. The lifting blocks extend into the support column and are connected to the first fixed wheel and the second fixed wheel through a retractable chain.

[0013] The input ends of both the first worm gear and the second worm gear extend outside the support column. The input ends of the first worm gear and the second worm gear are connected by a transmission chain, and the input end of the first worm gear is connected to a drive source.

[0014] A further technical solution is that the driving source is a servo motor.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. After the metal foil is laid flat and stabilized on the top surface of the placement plate, the press is started. The press sprays the active substance slurry from the infusion tank from the nozzle. Then, the drive motor is started, which drives the lead screw to rotate, causing the infusion tank to slide on the lead screw. At the same time, as the lead screw rotates, the press slides on the smooth plate along with the lead screw, evenly spraying the active substance slurry onto the metal foil through the nozzle at its bottom. This allows for batch spraying of the active substance slurry onto the placement plate.

[0017] 2. Start the compressor. Its output end will draw in air through multiple vent pipes. When the metal foil is laid flat on the placement plate, the negative pressure generated by the vent holes will stably hold the metal foil in place, improving the stability of the metal foil.

[0026] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0027] See Figures 1 to 6 This utility model provides a battery cell assembly structure for special vehicles, including a smooth plate 1, with multiple support columns 2 at the bottom of the smooth plate 1. A first horizontal plate 3 is provided between two adjacent support columns 2, and a drive motor 4 is fixedly mounted on the first horizontal plate 3. The output end of the drive motor 4 is connected to a lead screw 5, and the other end of the lead screw 5 is rotatably connected to a second horizontal plate 6 on the other side. A press 7 is slidably connected to the top surface of the smooth plate 1, and the output end of the press 7 passes through the smooth plate 1 and is connected to an infusion tank 8. A nozzle 9 is provided at the bottom of the infusion tank 8, and the infusion tank 8 is sleeved on the outer circumference of the lead screw 5. The infusion tank 8 slides back and forth in the lateral direction of the lead screw 5. A placement plate 10 is provided between the support columns 2, and the placement plate 10 is in contact with the nozzle 9.

[0028] Specifically, after the metal foil is laid flat and stabilized on the top surface of the placement plate 10, the press 7 is activated. The press 7 sprays the active substance slurry from the infusion tank 8 from the nozzle 9. Then, the drive motor 4 is started, which drives the lead screw 5 to rotate, causing the infusion tank 8 to slide on the lead screw 5. At the same time, as the lead screw 5 rotates, the press 7 slides on the smooth plate 1 along with the lead screw 5, uniformly spraying the active substance slurry onto the metal foil with the nozzle 9 at its bottom. This allows for the batch spraying of the active substance slurry onto the placement plate 10.

[0029] Preferably, the smooth plate 1 has a sliding strip hole 11, and the bottom of the press 7 has a slide rod 12, which is slidably connected to the inner wall of the sliding strip hole 11. The press 7 is a pneumatic motor.

[0030] A pneumatic motor is used as the power source to provide sufficient power to the infusion tank 8, facilitating the spraying of the active substance slurry from the nozzle 9. At the same time, when the lead screw 5 rotates, it drives the pneumatic motor to slide through the sliding bar hole 11 via the slide rod 12, thereby achieving uniform spraying of the active substance slurry.

[0031] Preferably, the nozzle 9 has a limiting strip hole 13 at the bottom, and the limiting strip hole 13 is connected to the infusion tank 8.

[0032] The limiting strip hole 13 is used to limit the amount of active material slurry output by the nozzle 9, to prevent excessive output of active material slurry, which would result in a thicker coating and affect the coating quality of the metal foil.

[0033] Preferably, the placement plate 10 is hollow, and a compressor 14 is installed inside the hollow. The output end of the compressor 14 is connected to multiple vent pipes 15. The top surface of the placement plate 10 is provided with multiple vent holes, and the multiple vent pipes 15 are respectively connected to the vent holes.

[0034] The compressor 14 is used to compress air to generate negative pressure. When the compressor 14 is started, the multiple vent pipes 15 at its output end complete the intake of air, and air is also generated in the vent holes. When the metal foil is laid flat on the placement plate 10, the negative pressure generated by the vent holes stably holds the metal foil in place, improving the stability of the metal foil's flatness.

[0035] In a preferred embodiment, the support column 2 is equipped with a lifting assembly connected to both sides of the placement plate 10. The lifting assembly includes a first worm gear 16, a first fixed wheel 17, a second worm gear 18, and a second fixed wheel 19. Lifting blocks 20 are provided on both sides of the placement plate 10, extending into the support column 2 and connected to the first fixed wheel 17 and the second fixed wheel 19 via a retractable chain 23. The input ends of the first worm gear 16 and the second worm gear 18 extend outside the support column 2. The input ends of the first worm gear 16 and the second worm gear 18 are connected via a transmission chain 21, and the input end of the first worm gear 18 is connected to a drive source 22. The drive source 22 is a servo motor.

[0036] It should be noted that the lifting assembly is used to lift the placement plate 10, which facilitates the separation of the placement plate 10 from the nozzle 9, and allows for the subsequent placement of metal foil, thereby improving space efficiency.

[0037] Specifically, the servo motor is started, driving the first worm gear 16, which in turn drives the second worm gear 18 to rotate via the transmission chain 21. The first and second worm gears 16 and 18, along with the first and second fixed wheels 17 and 19, retract the chain 23. The retracting chain 23 causes the lifting block 20 to rise, bringing the placement plate 10 into contact with the nozzle 9, facilitating the subsequent application of the active substance slurry to the nozzle 9. The servo motor then reverses, causing the placement plate 10 to descend, allowing workers to place the metal foil on its top surface.

[0038] It is worth noting that the inherent transmission ratio of the first worm gear 16 and the second worm gear 18 means that when the worm stops rotating, the worm gear also stops rotating due to its inherent transmission ratio, preventing the lifting block 20 from sliding up and down within the support column 2. This allows the placement plate 10 to be suspended at the position where the worm stops rotating, making it easier to control the lifting height of the placement plate 10.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
