Description

Technical Field

[0001] This utility model relates to the field of new energy equipment manufacturing, and in particular to a lithium battery production roller press. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They are characterized by high energy density, long lifespan, and low self-discharge rate, and are widely used in consumer electronics, new energy vehicles, energy storage systems, and other fields.

[0003] The lithium battery production roller press mainly consists of a roller system (usually a double roller with a high-precision surface treatment), a drive system (motor and reducer linked), a pressure regulation system (hydraulic or servo device controls the extrusion pressure), a feeding and discharging device, and an online detection system (such as a laser thickness gauge). Its working principle is that the drive system drives the rollers to rotate, introducing the positive and negative electrode sheets from the feeding end into the gap between the rollers. The pressure regulation system applies precise and controllable mechanical pressure, so that the electrode sheets achieve uniform thickness and increased density during the extrusion process. At the same time, the online detection device monitors the thickness accuracy in real time to ensure that the electrode sheets meet the high specifications required for lithium battery production.

[0004] In existing technologies, after the rolling rollers roll out the batteries, they cannot be stabilized, often resulting in displacement and instability. Furthermore, impurities such as electrode fragments, metal dust, and oil stains often remain on the surface of the rolling rollers, causing various adverse effects on equipment performance and product quality. The roller surface damage detection system also frequently malfunctions. In existing technologies, after the rolling rollers roll out the batteries, a clamping mechanism stabilizes them to prevent displacement, and a cleaning roller brush cleans the surface of the rolling rollers. Therefore, a lithium battery production roller press is proposed to solve the above problems. Utility Model Content

At the same time, the clamp is firmly inserted inward, thereby achieving the goal of clamping and stabilizing the battery when it is crushed out of the crushing wheel to prevent displacement.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a lithium battery production roller press, comprising two mounting columns 1. One mounting column 1 houses two motors a2 internally, each motor a2 driving two rotating shafts 4. The two rotating shafts 4 connect to two rolling rollers 3 on the outer left side of the battery rolling surface. A sliding block a5 is fixedly connected to the top of the mounting column 1. The sliding block a5 is used to assemble a sliding shaft 6, which is internally slidably connected to the sliding shaft 6. The reciprocating motion of the sliding shaft 6 drives an external sliding block b7. A cleaning roller brush 8 is fixedly connected to the bottom of the sliding shaft 6 to clean the surfaces of the two rolling rollers 3. A slider bearing a9 is fixedly connected to the bottom of the slider bearing a9, and a sliding block a10 is slidably connected inside the slider bearing a9. Block a10 is internally fixedly connected to a rotating column a11, which slides back and forth on a sliding shaft 6. The rotating column a11 is externally slidably connected to a sliding block a12, which drives the block to swing left and right. The sliding block a12 allows the sliding block b13 to slide inside it. The sliding block b13 is internally rotatably connected to a rotating rod column b14. The rotating rod column b14 causes the sliding block b13 to rotate during sliding. The external rotating rod column b14 is connected to a slider bearing shaft b15, which fixes the sensing shaft 16. The sensing shaft 16 is internally fixedly connected to a mounting column 1. A motor b18 is internally fixedly connected to one of the mounting columns 1. The drive end of the motor b18 is fixedly connected to the left side of the sensing shaft 16. The bottom of the sliding block a12 is fixedly connected to a rotating column c17, which provides a support point for the sliding block a12 during rotation.

[0031] Reference Figures 1 to 4A base plate 29 is fixedly connected to the bottom of the mounting column 1. A fixing plate 28 is fixedly connected to the top of the cylinder b30 device, which is supported by the base plate 29. The cylinder b30 is fixedly connected inside the fixing plate 28. A cylinder column a27 is fixedly connected to the drive end of the cylinder b30. A sliding block b25 is slidably connected to the bottom of the base plate 29. A movable slider 26 is slidably connected to the outside of the sliding block b25, providing a support point for the cylinder column a27. The movable slider 26 is fixedly connected to a support outside the sliding block b25, allowing it to slide back and forth. The column 24 is internally fixedly connected to a rotating column e23 for pushing. The rotating column e23 is externally rotatably connected to two connecting plates 22. The two connecting plates 22 are internally fixedly connected to two rotating columns d21 that slide inward. The rotating columns d21 cause the clamps 20 to move inward and stabilize the object. The two clamps 20 are externally fixedly connected to two clamps 20. The two clamps 20 are internally slidably connected to a positioning slider 19 that allows the clamps 20 to move on the positioning slider 19. The cleaning roller brush 8 is externally rotatably connected to the outside of the rolling wheel 3.

[0032] Working principle: The motor a2 inside the mounting column 1 drives the rotating shaft 4 to rotate and compact the roller 3. A sliding shaft 6 is inside the sliding block a5. At the bottom of the sliding block b7 is a sliding bearing a9, which contains a sliding block a10. When the rotating column a11 inside the sliding block a10 rotates, it drives the external bearing block a12 to slide. Simultaneously, a sliding block b13 slides in the middle of the bearing block a12. The rotating rod column b14 rotates, and a rotating column c17 at the bottom of the sliding bearing a15 rotates. A sensing shaft 16 inside the sliding bearing a15 connects to the motor b18, which drives the roller to rotate. The cylinders reciprocate on the surface of the sliding shaft 6, thereby driving the cleaning roller brush 8 on the sensing shaft 16 to clean the surface of the crushing wheel 3. The cylinder b30 is fixed on the fixed plate 28. The cylinder b30 and the cylinder column a27 drive the moving slider 26 at the bottom of the bearing slider b25 to slide back and forth. During the back and forth sliding, the connecting plate 22 on the rotating column e23 connected to the support column 24 is pushed forward. At the same time, the clamp 20 on the rotating column d21 slides on the positioning slider 19. At the same time, the clamp 20 slides inward until the battery base plate 29 crushed by the crushing wheel 3 is stabilized.
