Description

Technical Field

[0001] This invention belongs to the field of battery electrode production and processing technology, specifically a lithium-ion battery electrode production and processing equipment. Background Technology

[0002] Lithium-ion battery electrode production and processing equipment is used to process, cut, slit, and shape electrode materials (coated sheets for positive and negative electrodes) to ensure that the size, shape, and quality of the electrode meet the requirements of battery assembly. The role of the die-cutting machine in electrode production is to perform high-precision cutting of materials. It is usually used to cut electrode strips into specific shapes (such as rectangles, perforated shapes, strips, etc.) for subsequent assembly.

[0003] A Chinese patent with publication number CN116117927A discloses a continuous die-cutting machine for lithium battery electrodes, including a support frame, a feeding roller, a slitting assembly, and a die-cutting assembly. The support frame has a U-shaped cross-section, with the feeding roller installed on the left side inside the support frame, the slitting assembly installed in the middle of the support frame, and the die-cutting assembly installed on the right side inside the support frame. This invention can compress the battery electrode raw material, avoiding deviations in the electrode material size caused by material displacement. Simultaneously, the cutter holder can accurately perform die-cutting on the raw material. When the sliding plate moves inward, the die-cutting cutter holder first resets, ensuring that the pressure plate keeps the die-cut electrode material adhered to the lower die, preventing the electrode material from getting stuck between the die-cutting cutter holder and the pressure plate.

[0004] Existing die-cutting processes and equipment for new energy vehicle battery electrodes are not convenient for quickly adjusting the cutting size when producing lithium-ion battery electrodes. They lack flexibility in adjusting the cutting size, which limits the rapid adaptation to different specifications of electrodes and the improvement of production efficiency.

[0005] Therefore, the present invention provides a lithium-ion battery electrode production and processing equipment. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of the inconvenience of quickly cutting lithium-ion battery electrodes of different sizes, this invention proposes a lithium-ion battery electrode production and processing equipment.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: A lithium-ion battery electrode sheet production and processing equipment of the present invention includes a frame, a winding mechanism on the frame, an unwinding shaft on the frame, a tunnel fixedly connected to the top of the frame, an electric push rod on the tunnel, a concave frame inside the tunnel, and the telescopic end of the electric push rod fixedly connected to the top of the concave frame. A rotating rod is rotatably arranged inside the concave frame, a drive motor is fixedly arranged on the side of the concave frame, and the output end of the drive motor is fixedly connected to the end of the rotating rod. Cutting wheels are arranged in an array on the rotating rod, and a through groove corresponding to the cutting wheel is arranged inside the rotating rod. A sliding block is fixedly connected to the inner ring of the cutting wheel and passes through the through groove. A threaded rod is rotatably arranged inside the through groove, and the outer surface of the threaded rod is threadedly connected to the inner surface of the sliding block. Servo motors corresponding to the threaded rod are arranged in an array inside the rotating rod, and the output end of the servo motor is fixedly connected to the end of the threaded rod. An air jet mechanism for cooling the cutting wheel is arranged on the concave frame.

[0008] By sampling the above scheme, the unwinding shaft supports the wound lithium-ion battery electrode, allowing one end of the electrode to pass through the square frame and tunnel. Simultaneously, a rotating roller assists in the movement of the electrode, connecting it to the winding mechanism. The winding mechanism then winds the electrode, allowing it to move. The rotating roller further assists in this movement. During this movement, the drive motor rotates a rotating rod, which in turn rotates a cutting wheel. An electric push rod, via a concave frame, adjusts the positions of the rotating rod and the cutting wheel. Once the cutting wheel lowers and contacts the electrode, it performs cutting processing, facilitating the processing of the lithium-ion battery. The electrode sheets are processed into lithium-ion battery electrode sheets of different widths. When the cutting width needs to be adjusted, the servo motor drives the threaded rod to rotate. When the threaded rod rotates, the position of the sliding block is adjusted. When the sliding block moves, it drives the cutting wheel to move, thus adjusting the position of the cutting wheel. After the cutting wheel is moved to the predetermined position, the servo motor stops working, thereby achieving the purpose of adjusting the distance between adjacent cutting wheels. This facilitates the cutting and preparation of lithium-ion battery electrode sheets of different widths and improves the flexibility of lithium-ion battery electrode sheet production and processing equipment. When the rotating rod rotates, it drives the first fan to move and generate air force. The air force flows into the air jet mechanism. Through the air jet mechanism, the delivered air force flows over the surface of the cutting wheel, which can dissipate heat and cool the cutting wheel, and at the same time, it can clean the cutting wheel.

[0009] Preferably, a controller is fixedly installed on the side of the frame, a control module is installed inside the rotating rod, and the control module is electrically connected to the servo motor. A battery corresponding to the servo motor is arranged in an array inside the rotating rod, and the battery is electrically connected to the servo motor. A guide shaft is installed through the sliding block, and the end of the guide shaft is fixedly connected to the inner wall of the through groove. The controller is used to control the operation of the lithium-ion battery electrode production and processing equipment. A rotating roller to assist the movement of the battery electrode is installed inside the frame.

[0010] By adopting the above scheme, the controller is electrically connected to the electronic equipment on the lithium-ion battery electrode production and processing equipment, which can control the cutting and production of lithium-ion battery electrodes. The controller can remotely control the operation of the control module, and then the control module can control the operation of the servo motor, which will drive the threaded rod to rotate.

[0011] Preferably, the winding mechanism includes a winding rod, a stepper motor, and a bracket. The winding rod is rotatably connected to the inside of the bracket, the bracket is fixedly connected to the side of the frame, and a stepper motor is fixedly installed on the side of the bracket, with the output end of the stepper motor fixedly connected to the end of the winding rod.

[0012] By adopting the above scheme, after one end of the lithium-ion battery electrode is fixedly connected to the winding rod, controlling the stepper motor to work will drive the winding rod to rotate. The rotation of the winding rod can wind up the lithium-ion battery electrode, thereby enabling the lithium-ion battery electrode to move for cutting and processing.

[0013] Preferably, guide cylinders are symmetrically arranged at the top of the tunnel, and the guide cylinders are located on one side of the electric push rod. A guide rod is inserted inside the guide cylinder, and one end of the guide rod is fixedly connected to the top of the concave frame.

[0014] Preferably, a support block is provided inside the frame, and the support block is located directly below the cutting wheel. The top of the support block is provided with a groove corresponding to the cutting wheel.

[0015] By adopting the above scheme, when the electric push rod moves the concave frame, it will drive the guide rod to move. The guide rod and the guide cylinder will make the concave frame move smoothly, which can guide the concave frame and make it easy to cut the lithium-ion battery electrode sheets.

[0016] Preferably, the jetting mechanism includes a flow divider, which is located directly above the cutting wheel, and jet holes are arranged in an array on the flow divider.

[0017] Preferably, a bellows is embedded inside the concave frame, a first fan is installed inside the bellows, an impeller inside the first fan is fixedly connected to a rod, and the end of the rod is fixedly connected to the end of the rotating rod, and the output end of the first fan is connected to the diversion channel through a pipe.

[0018] Preferably, a square frame is fixedly installed inside the frame, and the square frame is located on one side of the unwinding shaft, and a load-bearing block is fixedly installed inside the square frame.

[0019] Preferably, the square frame is equipped with an array of air ducts, and the air ducts are equipped with an array of nozzles. An exhaust fan is installed inside the square frame, and the output end of the exhaust fan is connected to the air ducts through a pipe.

[0020] Preferably, the square frame has a storage slot inside, and the storage slot is located on one side of the load-bearing block. An intercepting net is fixedly installed inside the storage slot. A sliding groove is installed inside the storage slot, and a sealing plate passes through the sliding groove. A waste trough is fixedly connected to the side of the sealing plate, and the waste trough is located on one side of the intercepting net.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The lithium-ion battery electrode production and processing equipment of the present invention facilitates the adjustment of cutting size and improves cutting efficiency through the setting of a threaded rod. When adjusting the cutting width, the operation of the servo motor drives the threaded rod to rotate. When the threaded rod rotates, the position of the sliding block is adjusted. When the sliding block moves, it drives the cutting wheel to move, which can adjust the position of the cutting wheel. After the cutting wheel is moved to the predetermined position, the servo motor stops working, thereby achieving the purpose of adjusting the distance between adjacent cutting wheels. This facilitates the cutting and preparation of lithium-ion battery electrodes of different widths and improves the flexibility of the lithium-ion battery electrode production and processing equipment.

[0023] 2. The lithium-ion battery electrode production and processing equipment of the present invention facilitates the cleaning and cooling of the cutting blade through the set diversion groove and air jet hole. When the rotating rod rotates, it drives the first fan to move and generate wind. The wind flows into the air jet mechanism. After the wind flows into the diversion groove, it flows to the surface of the cutting wheel through the air jet hole, which can clean and cool the cutting wheel and ensure the cutting effect of the cutting wheel.

[0024] 3. The lithium-ion battery electrode production and processing equipment of the present invention facilitates the cleaning treatment of lithium-ion battery electrodes through the setting of an exhaust fan, an interception net, and a waste tank. The exhaust fan generates airflow, which flows into the air duct and is directed to one side by the nozzle. When the lithium-ion battery electrode slides inside the square frame, the airflow carries the impurities adsorbed on the surface of the lithium-ion battery electrode into the collection tank. The interception net filters and intercepts the flowing impurities. When the airflow stops, the intercepted impurities fall into the waste tank for collection. Pulling the sealing plate moves the waste tank, thereby removing the collected debris and achieving the purpose of cleaning the lithium-ion battery electrode. Attached Figure Description

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 9As shown in the embodiment of the present invention, a lithium-ion battery electrode production and processing equipment includes a frame 1, a winding mechanism and an unwinding shaft 3 on the frame 1, a tunnel 8 fixedly connected to the top of the frame 1, an electric push rod 9 on the tunnel 8, a concave frame 10 inside the tunnel 8, and the telescopic end of the electric push rod 9 fixedly connected to the top of the concave frame 10. A rotating rod 13 is rotatably mounted inside the concave frame 10, and a drive motor 15 is fixedly mounted on the side of the concave frame 10, with the output end of the drive motor 15 fixedly connected to the end of the rotating rod 13. The array is fitted with a cutting wheel 14. The rotating rod 13 has a through groove 17 corresponding to the cutting wheel 14. The inner ring of the cutting wheel 14 is fixedly connected with a sliding block 19, and the sliding block 19 passes through the through groove 17. A threaded rod 21 is rotatably arranged inside the through groove 17, and the outer surface of the threaded rod 21 is threadedly connected to the inside of the sliding block 19. The rotating rod 13 has an array of servo motors 22 corresponding to the threaded rod 21, and the output end of the servo motor 22 is fixedly connected to the end of the threaded rod 21. The concave frame 10 is equipped with an air jet mechanism for cooling the cutting wheel 14.

[0038] When cutting lithium-ion battery electrodes using lithium-ion battery electrode production and processing equipment, the unwinding shaft 3 supports the wound lithium-ion battery electrode, allowing one end of the electrode to pass through the square frame 30 and tunnel 8. Simultaneously, the rotating roller 4 assists in the movement of the lithium-ion battery electrode, connecting it to the winding mechanism. The winding mechanism moves to wind the lithium-ion battery electrode, thus allowing it to move. The rotating roller 4 further assists in this movement. During this movement, the drive motor 15 rotates the rotating rod 13, which in turn rotates the cutting wheel 14. The electric push rod 9, through the concave frame 10, adjusts the positions of the rotating rod 13 and the cutting wheel 14. After the cutting wheel 14 moves down and contacts the lithium-ion battery electrode, it can perform cutting processing, facilitating the separation and processing of the lithium-ion battery electrodes. To produce lithium-ion battery electrode sheets of different widths, when the cutting width needs to be adjusted, the servo motor 22 is controlled to rotate the threaded rod 21. When the threaded rod 21 rotates, the position of the sliding block 19 is adjusted. When the sliding block 19 moves, it drives the cutting wheel 14 to move, thus adjusting the position of the cutting wheel 14. After the cutting wheel 14 is moved to the predetermined position, the servo motor 22 stops working, thereby achieving the purpose of adjusting the spacing between adjacent cutting wheels 14. This facilitates the cutting and preparation of lithium-ion battery electrode sheets of different widths, improving the flexibility of the lithium-ion battery electrode sheet production and processing equipment. When the rotating rod 13 rotates, it drives the first fan 28 to move and generate wind. The wind flows into the air jet mechanism, and the air jet mechanism causes the delivered wind to flow over the surface of the cutting wheel 14, which can dissipate heat and cool the cutting wheel 14. At the same time, it can clean the cutting wheel 14, extend the service life of the cutting wheel 14, and ensure the cutting effect of the cutting wheel 14.

[0039] Furthermore, a controller 2 is fixedly installed on the side of the frame 1, a control module 16 is installed inside the rotating rod 13, and the control module 16 is electrically connected to the servo motor 22. A battery 18 corresponding to the servo motor 22 is arranged in an array inside the rotating rod 13, and the battery 18 is electrically connected to the servo motor 22. A guide shaft 20 is installed through the sliding block 19, and the end of the guide shaft 20 is fixedly connected to the inner wall of the through groove 17. The controller 2 is used to control the operation of the lithium-ion battery electrode production and processing equipment. A rotating roller 4 for assisting the movement of the battery electrode is installed inside the frame 1.

[0040] The controller 2 is electrically connected to the electronic equipment on the lithium-ion battery electrode production and processing equipment, and can control the cutting production of lithium-ion battery electrodes. The controller 2 can remotely control the operation of the control module 16, and then the control module 16 can control the operation of the servo motor 22. The operation of the servo motor 22 will drive the threaded rod 21 to rotate.

[0041] The servo motor 22 is model 80ST-M03520Z1 with a rated speed of 2000 r / min. The cutting wheel 14 is made of tungsten carbide as the base material and cobalt as the binder, with a hardness of 89-92 HRA and excellent wear resistance. It is suitable for medium and high speed cutting. The air jet hole 26 has a diameter of 5 mm.

[0042] Furthermore, the winding mechanism includes a winding rod 5, a stepper motor 6, and a bracket 7. The winding rod 5 is rotatably connected to the inside of the bracket 7. The bracket 7 is fixedly connected to the side of the frame 1. The stepper motor 6 is fixedly installed on the side of the bracket 7, and the output end of the stepper motor 6 is fixedly connected to the end of the winding rod 5.

[0043] After one end of the lithium-ion battery electrode is fixedly connected to the winding rod 5, the stepper motor 6 is controlled to drive the winding rod 5 to rotate. The rotation of the winding rod 5 can wind up the lithium-ion battery electrode, which in turn can move the lithium-ion battery electrode for cutting and processing.

[0044] Furthermore, guide cylinders 12 are symmetrically arranged on the top of tunnel 8, and the guide cylinders 12 are located on one side of the electric push rod 9. A guide rod 11 is inserted inside the guide cylinder 12, and one end of the guide rod 11 is fixedly connected to the top of the concave frame 10.

[0045] When the electric push rod 9 moves the concave frame 10, it will drive the guide rod 11 to move. The guide rod 11 and the guide cylinder 12 cooperate to make the concave frame 10 move smoothly. This can guide the concave frame 10 and make it move smoothly, which is convenient for cutting lithium-ion battery electrode sheets.

[0046] Furthermore, a support block 23 is provided inside the frame 1, and the support block 23 is located directly below the cutting wheel 14. The top of the support block 23 is provided with a groove 24 corresponding to the cutting wheel 14.

[0047] The support block 23 facilitates the movement of the lithium-ion battery electrode sheet. When the cutting wheel 14 cuts the lithium-ion battery electrode sheet, the groove 24 provides cutting space for the cutting wheel 14.

[0048] Furthermore, the jetting mechanism includes a flow divider 25, which is located directly above the cutting wheel 14, and jet holes 26 are arranged in an array on the flow divider 25.

[0049] After the first fan 28 operates and generates airflow, it enters the diversion groove 25 and then flows through the jet hole 26 to the surface of the cutting wheel 14, which can clean and cool the cutting wheel 14 and ensure the cutting effect of the cutting wheel 14.

[0050] Furthermore, a bellows 27 is embedded inside the concave frame 10, and a first fan 28 is installed inside the bellows 27. The impeller inside the first fan 28 is fixedly connected to a rod 29, and the end of the rod 29 is fixedly connected to the end of the rotating rod 13. The output end of the first fan 28 is connected to the diversion channel 25 through a pipe.

[0051] The concave frame 10 provides installation space for the bellows 27, and the bellows 27 provides installation space for the first fan 28. When the rotating rod 13 rotates, it will drive the first fan 28 to work through the rod body 29 to generate wind power. The wind power flows through the pipe and enters the diversion trough 25.

[0052] When the rotating rod 13 drives the first fan 28 to move and generate wind, compared with the traditional solution that relies on an independent motor power supply to drive the fan, this design does not require an additional power supply during the rotation process, thereby avoiding the accumulation of heat sources and achieving the goal of energy saving.

[0053] Furthermore, a square frame 30 is fixedly installed inside the frame 1, and the square frame 30 is located on one side of the unwinding shaft 3. A load-bearing block 31 is fixedly installed inside the square frame 30.

[0054] The frame 1 provides installation space for the square frame 30, and the square frame 30 provides installation space for the load-bearing block 31. When the lithium-ion battery electrode slides inside the square frame 30, the load-bearing block 31 facilitates the smooth movement of the lithium-ion battery electrode.

[0055] Furthermore, the square frame 30 is equipped with an array of air ducts 32, and the air ducts 32 are equipped with an array of nozzles 33. The square frame 30 is equipped with an exhaust fan 34, and the output end of the exhaust fan 34 is connected to the air duct 32 through a pipe.

[0056] The square frame 30 provides installation space for the air duct 32. The exhaust fan 34 generates airflow when it is working. After the airflow enters the air duct 32, it will flow to one side through the nozzle 33. After the airflow passes over the surface of the lithium-ion battery electrode, it can remove the impurities adsorbed on the surface of the lithium-ion battery electrode.

[0057] Furthermore, the square frame 30 is provided with a storage slot 35 inside, and the storage slot 35 is located on one side of the load-bearing block 31. An interception net 36 is fixedly installed inside the storage slot 35. A sliding groove 37 is provided inside the storage slot 35. A sealing plate 38 passes through the sliding groove 37. A waste trough 39 is fixedly connected to the side of the sealing plate 38, and the waste trough 39 is located on one side of the interception net 36.

[0058] After the wind flows over the surface of the lithium-ion battery electrode, it carries the impurities adsorbed on the surface of the lithium-ion battery electrode into the collection tank 35. The intercepting net 36 can filter and intercept the flowing impurities. When the wind stops flowing, the intercepted impurities will fall into the waste tank 39 for collection. Pulling the sealing plate 38 can move the waste tank 39, thereby cleaning up the collected debris.

[0059] Working principle: First, when cutting lithium-ion battery electrodes using lithium-ion battery electrode production and processing equipment, the unwinding shaft 3 supports the wound lithium-ion battery electrode, allowing one end of the electrode to pass through the square frame 30 and tunnel 8. Simultaneously, the rotating roller 4 assists in the movement of the lithium-ion battery electrode, connecting it to the winding mechanism. After one end of the electrode is fixedly connected to the winding rod 5, the stepper motor 6 drives the winding rod 5 to rotate. The rotation of the winding rod 5 winds up the lithium-ion battery electrode, thus allowing it to move. The rotating roller 4 also assists in the movement of the electrode. When the lithium-ion battery electrode moves, the drive motor 15 operates, causing the rotating rod 13 to rotate. The rotation of the rotating rod 13 then drives the cutting wheel 14 to rotate. The electric push rod 9, through the concave frame 10, can adjust the positions of the rotating rod 13 and the cutting wheel 14. After the cutting wheel 14 moves down and contacts the lithium-ion battery electrode, it can perform cutting processing, facilitating the separation and processing of lithium-ion battery electrodes into different widths. When the cutting width needs to be adjusted, the servo motor 22 operates, causing the threaded rod 21 to rotate. The rotation of the threaded rod 21 adjusts the position of the sliding block 19. When the sliding block 19 moves, it drives the cutting wheel 14 to move, allowing for position adjustment of the cutting wheel 14. After the cutting wheel 14 is moved to the predetermined position, the servo motor 22 stops working, thereby achieving the purpose of adjusting the spacing between adjacent cutting wheels 14. This facilitates the cutting and preparation of lithium-ion battery electrode sheets of different widths, improving the flexibility of lithium-ion battery electrode sheet production and processing equipment. When the rotating rod 13 rotates, it drives the first fan 28 to move and generate wind. The wind flows into the air jet mechanism and then into the diversion groove 25. Through the air jet holes 26, the wind flows to the surface of the cutting wheel 14, which can clean and degrade the cutting wheel 14. Temperature treatment ensures the cutting effect of the cutting wheel 14. The exhaust fan 34 generates wind, which flows into the air duct 32 and is directed to one side by the nozzle 33. When the lithium-ion battery electrode slides inside the square frame 30, the wind flows over the surface of the lithium-ion battery electrode and carries the impurities adsorbed on the surface of the lithium-ion battery electrode into the collection tank 35. The intercepting net 36 can filter and intercept the flowing impurities. When the wind stops flowing, the intercepted impurities will fall into the waste tank 39 for collection. Pulling the sealing plate 38 can move the waste tank 39, thereby cleaning the collected debris.
