Description

Technical Field

[0001] This utility model relates to the field of battery electrode roll-on adhesive technology, specifically a high-efficiency automated module for rolling-on adhesive on battery electrodes. Background Technology

[0002] In the field of new energy battery manufacturing, the tabs are key components that connect the positive and negative electrodes of the battery to the external circuit. The bonding quality between the tabs and the PP adhesive directly affects the sealing performance, structural stability and service life of the battery. In order to ensure the safety and reliability of the battery during use, the PP adhesive needs to be tightly bonded to the surface of the tab metal sheet through the roll bonding process to form an effective protective and insulating structure. Therefore, the bonding strength between the tab metal sheet and the PP adhesive is the core quality indicator of this production process. However, there is a common key technical problem in the existing production process of adhesive for bonding tab metal sheets: during transportation, storage and early processing, the surface of the tab metal sheet is prone to adsorbing dust, powder and other impurities from the environment. If these tiny impurities are not effectively cleaned, they will get stuck between the PP adhesive and the tab metal sheet during the bonding process, damaging the contact interface between the two. This results in the PP adhesive and the tab metal sheet not being firmly bonded, causing problems such as delamination and edge lifting, which seriously affects the quality and stability of battery products, and may even cause safety hazards such as battery short circuits and leakage. In the battery manufacturing industry, the adhesive application process for the metal tabs mainly relies on manual operation or semi-automatic equipment. Manual adhesive application has problems such as low bonding accuracy, poor adhesive layer flatness, and weak adhesion. In addition, manual operation is inefficient and labor-intensive, making it difficult to meet the needs of large-scale industrial production. Furthermore, manual operation is prone to waste of adhesive materials due to human factors, increasing production costs. While existing semi-automatic adhesive application equipment has improved production efficiency to some extent, it still suffers from several technical shortcomings: First, most of the equipment uses a single-station feeding structure, requiring the machine to be stopped and the tray replaced when the adhesive is used up, leading to production interruptions, low equipment utilization, and severely impacting production cycle time. Second, the adhesive is prone to loosening and wrinkling during transport, resulting in poor adhesion between the adhesive layer and the tab metal sheet during application, easily causing quality problems such as bubbles and edge lifting. Third, the surface of the tab metal sheet easily absorbs dust and impurities from the environment. If adhesive is applied directly without effective cleaning, the bonding strength between the adhesive layer and the metal sheet will be significantly reduced, affecting product reliability. Existing equipment lacks efficient synchronous cleaning and dust extraction mechanisms, resulting in poor cleaning effects. Fourth, the heating temperature, pressing force, and conveying speed of the adhesive are difficult to precisely control during the application process, making it difficult to balance application efficiency and bonding quality, and unable to flexibly adjust process parameters according to different production scenarios. Fifth, the cleaning components of some equipment are inconvenient to disassemble and assemble, and dust accumulates on the surface after long-term use, affecting the cleaning effect and resulting in high maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide an automated module for high-efficiency roll-on adhesive application of battery electrodes, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automated module for high-efficiency roll-on adhesive for battery electrodes, comprising a support frame, with feeding motors on both sides of the top of the support frame, and the output shaft of the feeding motors extending forward through the support frame and fixedly connected to a material tray. A tape feed roller is provided on the front surface of the support frame below the material tray, and a counterweight is provided on the right side of the front surface of the support frame to the tape feed roller. A pressing assembly is provided on the right side of the support frame, and a material support frame is provided at the inlet of the pressing assembly, with the side wall of the material support frame fixedly connected to the support frame. A support plate is provided at the inlet of the material support frame, and a rotating roller is rotatably connected inside the support plate. A cleaning roller is detachably connected to the outer wall of the rotating roller. A drive assembly is provided at the top of the support plate, and a groove plate is provided on the outer wall of the cleaning roller, with both sides of the groove plate connected to the support plate. A connecting pipe is fixed at the top of the groove plate.

[0005] Preferably, the connecting pipe is a corrugated pipe, and the other end of the connecting pipe is connected to the vacuum cleaner.

[0006] Preferably, slots are provided at all four corners of the outer wall of the rotating roller, and the slots are used for the installation and removal of the cleaning roller.

[0007] Preferably, the clamping assembly includes a first clamping roller, which is disposed at the bottom right side of the support frame, and a second clamping roller is disposed at the top of the first clamping roller.

[0008] Preferably, the first pressing roller and the second pressing roller are the same, and the first pressing roller and the second pressing roller correspond to each other.

[0009] Preferably, the first and second pressing rollers are composed of a cylinder and a pressing roller, with the cylinder providing power for the pressing roller to move up and down.

[0010] Preferably, the drive assembly consists of a motor and a pulley assembly. The motor is fixed to the top of the support plate. A first pulley is sleeved on the outer wall of the motor's output shaft. The first pulley is connected to a second pulley via a belt. The second pulley is fixed to the outer wall of the rotating roller and is used to transmit the motor's power to the rotating roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This automation module features two material trays on the left and right, along with matching feeding motors. It adopts a "single-station operation with the other station on standby" design. When the material in the current working tray is almost depleted, it can directly switch to the standby station for feeding without stopping the machine to wait for material replacement. This design completely solves the production interruption problem caused by material replacement in the traditional single-tray structure, effectively reduces equipment downtime, significantly improves the overall utilization rate of the equipment, ensures the continuity of the production process, and provides support for large-scale and efficient production. The tape feed roller area has a slight heating function, which can pre-treat the PP adhesive to improve the tape's adhesion and subsequent bonding effect. On the other hand, the counterweight continuously applies tension to the tape to ensure that the tape remains straight and taut throughout the rolling process, avoiding problems such as bonding misalignment and wrinkles caused by tape slack. The dual design works together to effectively improve the consistency and stability of the bonding between the tape and the tab metal sheet, and reduce the bonding failure rate. The material support rack can perform adjustable temperature heating on the tab metal sheet to adapt to different bonding process requirements, creating conditions for tight bonding between the tape and the metal sheet. At the same time, the drive component drives the cleaning roller to roll and clean the surface of the tab metal sheet. Combined with the dust collection structure composed of the groove plate, connecting pipe and dust collection equipment, it can adsorb the dust on the surface of the cleaning roller in real time, ensuring that the cleaning roller is always clean and avoiding dust residue affecting the bonding firmness. The synergistic realization of cleaning and heating functions solves the problem of weak bonding caused by dust and unsuitable temperature in the traditional rolling process from the source, significantly improving the product bonding quality. The clamping assembly consists of a first clamping roller and a second clamping roller, which are positioned at the top and bottom respectively. The roller speed can be flexibly adjusted, allowing for targeted adjustment of clamping parameters according to different working conditions such as electrode specifications and tape type in actual production, thereby maximizing production efficiency. At the same time, the cylinder-driven extrusion roller design can uniformly compact the bonded tape, further strengthening the bonding strength between the tape and the electrode tab metal sheet, preventing delamination during later use, and improving the product's structural stability and service life.

[0015] Please see Figure 1-4 This utility model provides a technical solution for an automated module for high-efficiency roll-on adhesive application of battery electrodes: an automated module for high-efficiency roll-on adhesive application of battery electrodes includes a support frame 1. The support frame 1 serves as the load-bearing foundation of the entire automated module and has good load-bearing capacity and anti-deformation performance. Feeding motors 2 are provided on both sides of the top of the support frame 1, and the output shaft of the feeding motor 2 extends forward through the support frame 1 and is fixedly connected to a material tray 3. There are two material trays 3, one on the left and one on the right. During operation, only one station needs to work. When the material is almost used up, the other station is switched to supply material, thereby realizing material change without stopping the machine and improving the utilization rate of the equipment. A tape feed roller 4 is provided on the front surface of the support frame 1 below the material tray 3. The area of ​​the tape feed roller 4 can slightly heat the tape and can sense the presence or absence of material. A counterweight 5 is provided on the right side of the tape feed roller 4 on the front surface of the support frame 1. The counterweight 5 is used to keep the tape in a straight and taut state during the roll-on process. A pressing assembly is provided on the right side of the support frame 1. A material support frame 8 is provided at the feed inlet of the pressing assembly, and the side wall of the material support frame 8 is fixedly connected to the support frame 1. The material support frame 8 can transport the tab metal sheet and heat it to a suitable temperature before rolling, and the temperature is adjustable, thereby achieving a better bonding effect for rolling. A support plate 9 is provided at the feed inlet of the material support frame 8. The support plate 9 is U-shaped and provides support for the rotating roller 10. The rotating roller 10 is rotatably connected inside the support plate 9. A cleaning roller 11 is detachably connected to the outer wall of the rotating roller 10. The cleaning roller 11 has a cylindrical structure. The length of the cleaning roller 11 is adapted to the width of the electrode plate, and the brush density is evenly distributed along the axial direction to ensure cleaning without dead angles. The top of the support plate 9 is equipped with a drive component. The outer wall of the cleaning roller 11 is provided with a groove plate 13, and the two sides of the groove plate 13 are connected to the support plate 9. The groove plate 13 is arc-shaped and has a cavity inside. Multiple air suction holes are opened on the surface. The top of the groove plate 13 is fixed with a connecting pipe 14. The connecting pipe 14 is a corrugated pipe, and the other end of the connecting pipe 14 is connected to a vacuum cleaner. The four corners of the outer wall of the rotating roller 10 are provided with slots for the installation and removal of the cleaning roller 11.

[0016] The clamping assembly includes a first clamping roller 6, which is located at the bottom right side of the support frame 1. A second clamping roller 7 is located at the top of the first clamping roller 6. The first clamping roller 6 and the second clamping roller 7 are identical and correspond to each other. The first clamping roller 6 and the second clamping roller 7 are composed of a cylinder and a squeeze roller. The cylinder provides the power for the squeeze roller to move up and down. As the tab metal sheet moves, the first clamping roller 6 and the second clamping roller 7 synchronously and evenly attach the tape to the surface of the tab sheet. Since the roller speed is adjustable, production efficiency can be maximized according to the actual production situation.

[0018] Working Principle: When a high-efficiency automated module for rolling adhesive application of battery electrodes is first used, the feeding motor 2 starts working, driving the material tray 3 to rotate. As the tray 3 rotates, the PP adhesive on its surface is conveyed to the conveyor roller 4, where it is heated. After heating, the adhesive is kept taut by a counterweight 5 until it adheres to the electrode tab metal sheet. While the tray 3 is working, the electrode tab metal sheet moves to the right via the material support frame 8. When it passes the cleaning roller 11, the rotation of the motor 12, in conjunction with the pulley assembly, transmits power from the motor 12 to the rotating roller 10. The rotating roller 10 then drives the cleaning roller 11 simultaneously. The dust on the surface of the tab metal sheet is rotated and cleaned to prevent the adhesive from sticking firmly when it is bonded to the PP adhesive. During the cleaning process, an external vacuum cleaner is used to apply suction through the connecting pipe 14 and the groove plate 13 to remove the dust from the surface of the cleaning roller 11. This keeps the surface of the cleaning roller 11 clean. After cleaning, the tab metal sheet is moved to the right by the material support 8 and bonded to the PP adhesive. After bonding, the bonding position is pressed firmly by the cooperation of the first pressing roller 6 and the second pressing roller 7 to ensure that the PP adhesive is firmly bonded to the tab metal sheet.
