[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. With their core advantages such as high energy density, long cycle life, low self-discharge rate, and environmental friendliness, they have become the core energy storage carrier in the global new energy field and are widely used in consumer electronics, new energy vehicles, energy storage power stations, aerospace and other fields.

[0003] The aluminum foil packaging machine for lithium battery electrode rolls is one of the key pieces of equipment in the back end of lithium battery production. It is specifically used to vacuum seal the core component of lithium batteries, the "electrode rolls," in aluminum foil bags.

Detailed Implementation

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1-7This application discloses an aluminum foil packaging machine for lithium battery electrode rolls. The machine includes a frame 1, which integrates a material rack, a heat sealing machine 2, a vacuum mechanism 5, a control cabinet 3, and an industrial control all-in-one computer 4. The control cabinet 3 is electrically connected to the industrial control all-in-one computer 4 for overall equipment operation control. The material rack carries the electrode rolls to be packaged. The heat sealing machine 2 is located inside the material rack and includes an upper cover 21, a wire groove 22, a foot pedal 23, a touch screen 24, a Y-axis module 25, a heating transformer 26, a Y-axis servo motor 27, a vacuum solenoid valve assembly 28, a bag opening tensioning assembly 29, a Z-axis servo motor 30, a vacuuming assembly 31, a heat sealing assembly 32, a bag opening pre-clamping assembly 33, a heat sealing control box 34, and a solenoid valve control box 35. The touch screen 24 is electrically connected to the industrial control all-in-one computer 4 for parameter setting and operating status display. The vacuum mechanism 5 is connected to the vacuuming assembly 31 of the heat sealing machine 2. The sealed connection includes a vacuum pump 52, sound insulation cotton 51, air intake assembly 53, vacuum tank 54, and negative pressure gauge 55. The sound insulation cotton 51 is wrapped around the outside of the vacuum pump 52, and the negative pressure gauge 55 is used to detect the vacuum level in real time. Among them, the bag opening tensioning assembly 29 is symmetrically arranged in two sets, each set including a linear guide rail 291, a tensioning cylinder 292, and two grippers 293. The grippers 293 are used to clamp the side of the aluminum foil bag. The bag opening pre-clamping assembly 33 includes a clamping adjustment cylinder 331 and a clamping silicone 332, which is used to pre-fix the bag opening of the aluminum foil bag. The vacuuming assembly 31 includes a vacuum nozzle 311, a vacuum detection nozzle 312, a vacuum sensor 313, a linear module 314, and a servo motor 315, which is used to realize the staged vacuuming operation of first fast and then slow speed. The heat sealing assembly 32 includes a heat sealing head 321 and a clamping cylinder 322. The heat sealing head 321 is electrically connected to the heating transformer 26, which is used to complete the heat sealing of the aluminum foil bag opening.During equipment operation, the electrode rolls to be packaged are placed on the rack on the frame 1. The control cabinet 3 and the industrial control all-in-one computer 4 are electrically connected to achieve overall control. The heat sealing machine 2 starts operation on the inner side of the rack. The touch screen 24 and the industrial control all-in-one computer 4 work together to complete parameter setting and status display. The vacuum mechanism 5 and the vacuum pumping component 31 are sealed and connected. The sound insulation cotton 51 wraps the vacuum pump 52 to reduce operating noise. After the electrode rolls are packaged in aluminum foil bags, in the two sets of symmetrically arranged bag opening tensioning components 29, the linear guide rail 291 works with the tensioning cylinder 292 to drive the two grippers 293 to clamp the sides of the aluminum foil bag. The clamping adjustment cylinder 331 of the bag opening pre-clamping component 33 pushes the clamping silicone 332 to pre-fix the bag opening. Then, the servo motor 315 of the vacuum pumping component 31 drives the linear module 314 to drive the vacuum nozzle 311 to approach the bag opening and perform a staged vacuuming operation with a fast speed followed by a slow speed. The vacuum detection nozzle 312 works with the vacuum sensor 313 to monitor the vacuum status. After reaching the target, the heat sealing head 321 of the heat sealing assembly 32 is powered by the heating transformer 26, and the clamping cylinder 322 pushes the heat sealing head 321 to complete the heat sealing of the bag opening. The Y-axis servo motor 27, Y-axis module 25, and Z-axis servo motor 30 assist the heat sealing assembly 32 in adjusting its position. The vacuum solenoid valve assembly 28, heat sealing control box 34, and solenoid valve control box 35 coordinately control the actions of each component. This step solves the problems of the existing lithium battery electrode roll aluminum foil packaging equipment, such as the decentralized layout, cumbersome process, uneven vacuum extraction, and poor bag opening treatment effect. By integrating the material rack, heat sealing machine 2, vacuum mechanism 5, etc. into the frame 1, the packaging process is simplified and the equipment integration is improved. The design of staged vacuuming avoids residual air in the bag. The coordinated cooperation of the bag opening tensioning assembly 29 and the bag opening pre-clamping assembly 33 enhances the bag opening fixation effect, effectively ensuring the sealing performance of the aluminum foil bag. At the same time, the design to adapt to different specifications of electrode rolls expands the applicability of the equipment.

[0019] Reference Figures 1-7Vacuum tank 54 is sealed and connected to air intake assembly 53 via a pipe. The output end of vacuum pump 52 is fixedly connected to vacuum tank 54. Negative pressure gauge 55 is installed on top of vacuum tank 54. When vacuum mechanism 5 is running, vacuum tank 54 is sealed and connected to air intake assembly 53 via a pipe. The output end of vacuum pump 52 is fixedly connected to vacuum tank 54. After vacuum pump 52 starts, it stably supplies gas to vacuum tank 54. Negative pressure gauge 55 installed on top of vacuum tank 54 collects pressure data inside the tank in real time and feeds the data back to industrial control computer 4. Operators can view the vacuum status in real time through touch screen 24. When the pressure deviates from the set range, the operating parameters of vacuum pump 52 can be adjusted in time. This step solves the problems of untimely vacuum monitoring and inability to quickly detect pressure fluctuations in existing vacuum systems. The sealed connection between vacuum tank 54 and air intake assembly 53 ensures the stability of vacuum supply. The real-time feedback from negative pressure gauge 55 allows operators to accurately control the vacuum status, avoiding poor sealing and protection effect due to insufficient vacuum or damage to aluminum foil bags due to excessive vacuum, thus improving the reliability of vacuum sealing.

[0020] Reference Figures 1-7 The Y-axis servo motor 27 and the Y-axis module 25 work together to drive the heat-sealing assembly 32 to move precisely above the electrode roll along the Y-axis direction. The Z-axis servo motor 30 drives the heat-sealing assembly 32 to adjust its height along the Z-axis direction. Before the heat-sealing operation, the Y-axis servo motor 27 and the Y-axis module 25 work together. The Y-axis servo motor 27 outputs power to drive the Y-axis module 25 to move horizontally, thereby driving the heat-sealing assembly 32 to move precisely above the electrode roll. When there is a difference in the height of the electrode roll, the Z-axis servo motor 30 starts and outputs power to drive the heat-sealing assembly 32 to move precisely above the electrode roll. The heat-sealing assembly 32 moves up and down vertically until it is at the appropriate working height to match the opening of the aluminum foil bag. This step solves the problem of low positioning accuracy and inability to adapt to different heights of the existing heat-sealing assembly 32. The transmission cooperation between the Y-axis servo motor 27 and the Y-axis module 25 achieves precise horizontal positioning of the heat-sealing assembly 32. The lifting adjustment driven by the Z-axis servo motor 30 adapts to the packaging requirements of different heights of the aluminum foil bag, improving the accuracy of the heat-sealing operation and the compatibility of the equipment, and reducing problems such as missing seals and uneven sealing edges caused by positioning deviations.

[0021] Reference Figures 1-7The gripper 293 is an elastic structure with an anti-slip rubber pad fixedly installed on its inner wall. The tensioning cylinder 292 slides in conjunction with the linear guide rail 291, which can drive the gripper 293 to move smoothly along the linear guide rail 291. The clamping silicone 332 is fixed to the output end of the clamping adjustment cylinder 331, and its surface is provided with anti-slip texture. During the bag opening clamping operation, the gripper 293 of the bag opening tensioning assembly 29 adopts an elastic structure. The anti-slip rubber pad fixed on its inner wall increases the friction with the side of the aluminum foil bag. The tensioning cylinder 292 slides in conjunction with the linear guide rail 291. When the tensioning cylinder 292 extends or retracts, it drives the gripper 293 to move smoothly along the linear guide rail 291, realizing a stable clamping of the side of the aluminum foil bag, and at the same time, pre-clamping the bag opening. The clamping adjustment cylinder 331 of the clamping component 33 pushes the clamping silicone 332 at the output end to adhere to the opening of the aluminum foil bag. The anti-slip texture on the surface of the clamping silicone 332 further enhances the clamping stability and prevents the bag opening from shifting. This step solves the problems of existing bag opening clamping mechanisms, such as insecure clamping, easy bag opening shifting, and easy damage to the aluminum foil bag. The elastic structure of the gripper 293 and the anti-slip rubber pad enhance the clamping stability and prevent damage to the aluminum foil bag. The sliding cooperation between the tensioning cylinder 292 and the linear guide 291 ensures the smoothness of the clamping action. The anti-slip texture of the clamping silicone 332 further improves the pre-clamping effect, effectively preventing bag opening shifting during vacuuming and heat sealing, and ensuring the packaging quality.

[0022] Reference Figures 1-7 The servo motor 315 is driven by the linear module 314 to precisely move the vacuum nozzle 311. The vacuum sensor 313 works in conjunction with the vacuum detection nozzle 312 to detect the vacuum level inside the aluminum foil bag. The heat sealing control box 34 can adjust the heating temperature and heat sealing time of the heat sealing head 321. During the vacuuming operation, the servo motor 315 is driven by the linear module 314. After the servo motor 315 starts, it drives the linear module 314 to run, driving the vacuum nozzle 311 to precisely move to the corresponding position at the opening of the aluminum foil bag. 312 is attached to the inner wall of the aluminum foil bag. The vacuum sensor 313 works with the vacuum detection nozzle 312 to collect the vacuum level data inside the bag. When the vacuum level reaches the set threshold, the vacuum sensor 313 sends a start signal to the heat sealing control box 34. During the heat sealing operation, the operator can adjust the heating temperature and heat sealing time of the heat sealing head 321 through the heat sealing control box 34. This step solves the problems of inaccurate positioning of the existing vacuum component 31, inaccurate vacuum level detection, and heat sealing parameters that cannot be adapted to different aluminum foil bags, thus improving the adaptability of the equipment and the consistency of heat sealing quality.

[0023] Reference Figures 1-7The solenoid valve control box 35 is electrically connected to the vacuum solenoid valve assembly 28, clamping cylinder 322, tensioning cylinder 292, and clamping adjusting cylinder 331, respectively; the bottom of the frame 1 is equipped with anti-slip pads; the upper cover 21 is made of transparent acrylic material; the industrial control all-in-one computer 4 has a built-in data storage module; during equipment operation, the solenoid valve control box 35 is electrically connected to the vacuum solenoid valve assembly 28, clamping cylinder 322, tensioning cylinder 292, and clamping adjusting cylinder 331, respectively, and precisely controls the action sequence of each pneumatic component according to the preset program; the bottom of the frame 1... Anti-slip foot pads increase friction with the ground, improving the stability of the equipment during operation; the upper cover 21 of the heat sealing machine 2 is made of transparent acrylic material, allowing operators to observe the sealing process in real time through the upper cover 21; the data storage module built into the industrial control all-in-one computer 4 automatically records parameters such as vacuum degree, heat sealing temperature, and heat sealing time for each sealing process, and supports data export through external devices to achieve quality traceability of the production process. This step solves the problems of chaotic pneumatic component action sequence, poor operational stability, inconvenient observation of the sealing process, and inability to trace production parameters in existing equipment.

[0024] In summary, when the lithium battery electrode roll aluminum foil packaging machine disclosed in this application is in use, the electrode roll to be packaged is placed on the rack on the frame 1 during operation. The control cabinet 3 and the industrial control all-in-one computer 4 are electrically connected to achieve overall control. The heat sealing machine 2 starts operation on the inner side of the rack. The touch screen 24 and the industrial control all-in-one computer 4 work together to complete parameter setting and status display. The vacuum mechanism 5 and the vacuum pumping component 31 are sealed and connected. The sound insulation cotton 51 wraps the vacuum pump 52 to reduce operating noise. After the electrode roll is packaged in an aluminum foil bag, in the two sets of bag opening tightening components 29 symmetrically arranged, the linear guide rail 291 cooperates with the tightening cylinder 292 to drive the two grippers 293 to clamp the side of the aluminum foil bag. The clamping adjustment cylinder 331 of the bag opening pre-clamping component 33 pushes the clamping silicone 332 to pre-fix. At the bag opening, the servo motor 315 of the vacuum assembly 31 drives the linear module 314 to bring the vacuum nozzle 311 close to the bag opening, performing a staged vacuuming operation with a fast speed followed by a slow speed. The vacuum detection nozzle 312, in conjunction with the vacuum sensor 313, monitors the vacuum status. Once the vacuum level meets the standard, the heat sealing head 321 of the heat sealing assembly 32 is powered by the heating transformer 26, and the clamping cylinder 322 pushes the heat sealing head 321 to complete the heat sealing of the bag opening. The Y-axis servo motor 27, the Y-axis module 25, and the Z-axis servo motor 30 assist the heat sealing assembly 32 in adjusting its position. The vacuum solenoid valve assembly 28, the heat sealing control box 34, and the solenoid valve control box 35 work together to control the actions of each component. When the vacuum mechanism 5 is running, the vacuum tank 54 maintains a sealed connection with the air intake assembly 53 through a pipe. The output end of vacuum pump 52 is fixedly connected to vacuum tank 54. After vacuum pump 52 starts, it stably supplies gas to vacuum tank 54. The negative pressure gauge 55 installed on the top of vacuum tank 54 collects the pressure data inside the tank in real time and feeds the data back to industrial control computer 4. The operator can view the vacuum status in real time through touch screen 24. When the pressure deviates from the set range, the operating parameters of vacuum pump 52 can be adjusted in time. Before heat sealing operation, Y-axis servo motor 27 and Y-axis module 25 form a transmission cooperation. Y-axis servo motor 27 outputs power to drive Y-axis module 25 to move horizontally, thereby driving heat sealing component 32 to move precisely above the pole roll. When there is a difference in pole roll height, Z-axis servo motor 30 starts and outputs power to drive heat sealing component 32 vertically. The device is raised and lowered until the heat-sealing assembly 32 and the aluminum foil bag opening are at the appropriate working height. During the bag opening clamping operation, the gripper 293 of the bag opening tensioning assembly 29 has an elastic structure, and the anti-slip rubber pad fixed on its inner wall increases the friction with the side of the aluminum foil bag. The tensioning cylinder 292 slides and engages with the linear guide rail 291. When the tensioning cylinder 292 extends and retracts, it drives the gripper 293 to move smoothly along the linear guide rail 291, achieving a stable clamping of the side of the aluminum foil bag. At the same time, the clamping adjustment cylinder 331 of the bag opening pre-clamping assembly 33 pushes the clamping silicone 332 at the output end to fit against the aluminum foil bag opening. The anti-slip texture on the surface of the clamping silicone 332 further enhances the clamping stability and prevents the bag opening from shifting. During the vacuuming operation, the servo motor 315 is connected to the linear module 314 for transmission.After the servo motor 315 starts, it drives the linear module 314 to run, which in turn moves the vacuum nozzle 311 precisely to the corresponding position at the opening of the aluminum foil bag. The vacuum detection nozzle 312 is in contact with the inner wall of the aluminum foil bag. The vacuum sensor 313 works with the vacuum detection nozzle 312 to collect the vacuum level data inside the bag. When the vacuum level reaches the set threshold, the vacuum sensor 313 sends a start signal to the heat sealing control box 34. During the heat sealing operation, the operator can adjust the heating temperature and heat sealing time of the heat sealing head 321 through the heat sealing control box 34. During the operation of the equipment, the solenoid valve control box 35 is connected to the vacuum solenoid valve. Component 28, clamping cylinder 322, tensioning cylinder 292, and clamping adjusting cylinder 331 are electrically connected, precisely controlling the timing of each pneumatic component's action according to a preset program. Anti-slip pads at the bottom of the frame 1 increase friction with the ground, improving equipment stability during operation. The upper cover 21 of the heat sealing machine 2 is made of transparent acrylic, allowing operators to observe the sealing process in real time. The built-in data storage module of the industrial control all-in-one computer 4 automatically records parameters such as vacuum degree, heat sealing temperature, and heat sealing time for each sealing operation, supporting data export via external devices to achieve quality traceability throughout the production process.
