Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a cleaning device. Background Technology

[0002] In the production of lithium batteries, the coating process is one of the key steps. This process involves uniformly coating a liquid slurry onto a substrate, and then evaporating the solvent in the slurry by heating and drying, allowing the solid material to adhere to the surface of the substrate, ultimately forming the battery electrode. The coating process plays a crucial role in the stability and consistency of battery performance, and the back roller, as a support and transmission component, plays an indispensable role in this process.

[0003] The back roller is in direct contact with the electrode sheet, and its surface condition significantly affects the coating quality. During production, carbon powder, impurities, and other particles easily detach from the electrode sheet surface, and these substances often adhere to the back roller surface. As the coating process continues, these impurities gradually accumulate on the back roller surface, forming a foreign matter layer. These foreign matter not only reduces the smoothness of the back roller surface but also, during subsequent production processes, can fall onto newly coated electrodes due to the rotation of the back roller, causing defects such as granular protrusions and uneven coating on the electrode surface. Such defects severely affect the quality of the electrode sheet, thereby impacting the overall performance of the lithium battery and leading to batches of defective products.

[0004] Currently, there is no effective back roller cleaning solution in lithium battery production, making it impossible to remove accumulated impurities from the back roller surface in a timely manner. Due to the lag in the cleaning process, production lines often need to be stopped frequently for manual cleaning, resulting in low production efficiency. Furthermore, untimely cleaning can lead to prolonged quality fluctuations. In addition, when foreign objects adhere to the back roller surface, production personnel often fail to detect them immediately, leading to a large number of defective products and seriously affecting production stability.

[0005] Therefore, a new cleaning solution is urgently needed to address the problem of removing foreign matter from the back roller surface in order to ensure the smooth progress of the lithium battery coating process and the stability of electrode quality. Utility Model Content

[0006] In order to improve the problem that the accumulation of foreign matter on the back roller in the prior art cannot be removed in time, which affects the quality of the electrode sheet, increases the production defect rate, and reduces the production efficiency, this application provides a cleaning device.

[0007] The cleaning device provided in this application adopts the following technical solution:

[0008] A cleaning device includes a scraper assembly, a drive component, a fine-tuning component, and a dust collection component. The drive component is connected to the scraper assembly and is used to drive the scraper assembly forward and backward. The fine-tuning component is disposed on the scraper assembly and is used to fine-tune the position of the scraper assembly to the object to be cleaned. The dust collection component is disposed below the scraper assembly.

[0009] By adopting the above technical solution, through the design of the drive component and fine-tuning component, the scraper assembly can be accurately adjusted to the optimal position of the object to be cleaned, ensuring that the distance between the scraper assembly and the object to be cleaned is appropriate, avoiding damage to the object due to excessive tightness, or poor cleaning effect due to excessive looseness, thereby improving cleaning efficiency and quality; the dust collection component recovers the scraped foreign objects during the cleaning process, effectively avoiding the re-accumulation and diffusion of impurities, reducing possible pollution during the cleaning process, and ensuring stable material quality during the production process.

[0010] In one specific implementation, the scraper assembly includes a scraper holder, a scraper, and an adjustment bracket, with the scraper mounted on the scraper holder, the fine-tuning component mounted on the scraper holder via the adjustment bracket, and the drive unit connected to the adjustment bracket.

[0011] By adopting the above technical solution, the movement of the adjustment frame is controlled by the drive component, and the position of the scraper is finely adjusted by the fine-tuning component. This allows for accurate control of the distance between the scraper and the object to be cleaned, ensuring that the scraper works in the optimal contact state, reducing the friction between the scraper and the object surface, avoiding damage, and extending its service life.

[0012] In one specific implementation, the scraper is fixed to the scraper holder by a fixing block.

[0013] By adopting the above technical solution, the fixing block applies appropriate clamping force to a local position of the scraper, which solves the problem of deformation caused by excessive length of the scraper, ensuring that the scraper is always in the ideal shape during use and avoiding performance degradation caused by deformation.

[0014] In one specific implementation, the fixing blocks are provided in multiple form and are distributed at intervals along the length direction of the scraper.

[0015] By adopting the above technical solution, and using multiple fixing blocks spaced apart along the length of the scraper, it can be ensured that the scraper is subjected to uniform clamping force throughout its entire length. This uniform clamping force helps maintain the shape and stability of the scraper, avoids local deformation, and thus improves the uniformity of the cleaning effect.

[0016] In one specific implementation, the drive unit is located on the side of the adjustment frame away from the scraper frame, and the drive unit includes a cylinder, the extension rod of which is connected to the adjustment frame.

[0017] By adopting the above technical solution and using a cylinder as the driving method, the adjusting frame can complete a large displacement in a short time, with high efficiency and response speed. Furthermore, by placing the driving component on the side of the adjusting frame away from the scraper frame, not only is the spatial layout optimized, but the stability and reliability of the cylinder driving system are also ensured.

[0018] In one specific implementation, the fine-tuning component includes a screw and a knob. One end of the screw passes through the adjustment frame and is fixed to the scraper frame, while the other end is connected to the knob. The knob is located on the side of the adjustment frame away from the scraper frame. A nut is threaded onto the screw, and the nut abuts against the side of the adjustment frame near the scraper frame.

[0019] By adopting the above technical solution, the design has a simple operation method. The operator only needs to loosen the nut and rotate the knob to complete the adjustment. The operation steps are clear and easy to implement. The knob is located in an easy-to-operate position. No special tools are required when rotating it. The adjustment can be completed directly by manual rotation.

[0020] In one specific implementation, a scale marking structure is further included, which is arranged along the moving direction of the scraper assembly to indicate the moving position of the scraper.

[0021] By adopting the above technical solution, the scale marking structure can reflect the movement position of the scraper, helping the operator to accurately judge the position of the scraper, thereby reducing errors during fine-tuning.

[0022] In one specific implementation, the dust collection assembly includes a dust collection box and a negative pressure adsorption structure disposed within the dust collection box, the dust collection box being located below the scraper assembly.

[0023] By adopting the above technical solution and utilizing the design of the dust collection box and negative pressure adsorption structure, impurities removed by the scraper assembly can be adsorbed and collected, reducing the scattering of impurities, maintaining a clean working environment, efficiently collecting waste materials, avoiding the waste of time in manual cleaning, and improving the efficiency of the entire operation process.

[0024] In one specific implementation, the negative pressure adsorption structure is a centrifugal fan or a vacuum pump used to create a negative pressure environment inside the dust collection box.

[0025] By adopting the above technical solution, the negative pressure environment generated by the centrifugal fan or vacuum pump can effectively adsorb and collect the impurities removed by the scraper assembly, prevent the impurities from spreading outside the working area, effectively maintain the cleanliness and hygiene of the working environment, and improve the collection efficiency of impurities.

[0026] In one specific implementation, a pressure sensor and an alarm unit are also included. The pressure sensor is used to monitor the pressure applied by the scraper assembly to the object to be cleaned and outputs a signal to the alarm unit, which is used to issue an alarm when the pressure value exceeds a preset range.

[0027] By adopting the above technical solution, the pressure applied by the scraper assembly is monitored in real time, which avoids damage to the object being cleaned or the scraper assembly due to excessive or insufficient pressure. Excessive pressure may cause damage to the surface of the object or damage to the scraper assembly, while insufficient pressure may result in unsatisfactory cleaning results. The pressure sensor and alarm unit work together to avoid operational errors caused by excessive or insufficient pressure, thereby improving the safety and stability of operation.

[0028] In summary, the beneficial technical effects of this application are as follows: The cleaning device of this application has the function of accurately adjusting the distance between the scraper assembly and the object to be cleaned, ensuring the best cleaning effect without damaging the object or the scraper assembly; through the design of the drive component and the fine-tuning component, the scraper position can be adjusted efficiently, extending the scraper's service life and improving the cleaning quality; by using a dust collection component with a negative pressure adsorption structure, impurities in the cleaning process can be effectively recovered, preventing pollution diffusion and maintaining a clean working environment, thus increasing operational efficiency; furthermore, the combination of a pressure sensor and an alarm system improves operational safety and stability; the overall solution achieves a highly efficient, stable, safe, and environmentally friendly cleaning effect.

Detailed Implementation

[0032] Reference Figure 1 This application discloses a cleaning device that can be applied in the lithium battery production process, especially suitable for cleaning the back roller in the coating process. Specifically, it relates to a device that can efficiently clean the surface of the back roller 7 and recover impurities. The following describes this application in further detail with reference to the accompanying drawings.

[0033] The cleaning device includes a scraper assembly 1, a drive unit 2, a fine-tuning unit 3, and a dust collection unit 4. The drive unit 2 is connected to the scraper assembly 1 and is used to drive the scraper assembly 1 forward and backward. The fine-tuning unit 3 is located on the scraper assembly 1 and is used to fine-tune the position of the scraper assembly 1 to the back roller 7. The dust collection unit 4 is located below the scraper assembly 1.

[0034] During operation, the drive unit 2 is activated, which drives the scraper assembly 1 to move close to the back roller 7. Then, the position of the scraper assembly 1 to the back roller 7 is finely adjusted by the fine-adjustment component 3 to ensure that the distance between the scraper 12 and the back roller 7 is appropriate. When the scraper assembly 1 is cleaning, the scraped impurities are collected by the dust collection component 4. The dust collection component 4 effectively removes these impurities by adsorption or collection, preventing them from re-accumulating or contaminating the back roller 7, thereby ensuring the continuous and efficient operation of the equipment.

[0035] Through the design of the drive component 2 and the fine-tuning component 3, the scraper assembly 1 can be accurately adjusted to the optimal position of the back roller 7, ensuring that the distance between the scraper assembly 1 and the back roller 7 is appropriate, avoiding damage to the back roller 7 due to excessive tightness or affecting the cleaning effect due to excessive looseness, thereby improving cleaning efficiency and quality; the dust collection component 4 recovers the scraped foreign objects during the cleaning process, effectively avoiding the re-accumulation and diffusion of impurities, reducing possible pollution during the cleaning process, and ensuring stable material quality during the production process.

[0036] In this embodiment, the scraper assembly 1 includes a scraper holder 11, a scraper 12 and an adjusting frame 13. The scraper 12 is mounted on the scraper holder 11. In this embodiment, the scraper 12 is arranged along the axial direction of the back roller 7. The material of the scraper 12 includes, but is not limited to, stainless steel, polyurethane or ceramic composite material.

[0037] The scraper 12 is fixed to the scraper holder 11 by fixing blocks 5. There are multiple fixing blocks 5, which are distributed at intervals along the length of the scraper 12. In this embodiment, the fixing blocks 5 include, but are not limited to, being connected to the scraper 12 and the scraper holder 11 by screws. The fixing blocks 5 apply appropriate clamping force to local positions of the scraper 12 to prevent the scraper 12 from deforming during use and to ensure the stability of the scraper 12 throughout the cleaning process. The design of multiple fixing blocks 5 ensures that the scraper 12 is subjected to uniform clamping force throughout its entire length, thereby avoiding local deformation.

[0038] The fine-tuning component 3 is located on the side of the scraper holder 11 away from the scraper 12. The fine-tuning component 3 is mounted on the scraper holder 11 via the adjusting frame 13. The fine-tuning component 3 adjusts the position of the scraper 12 relative to the adjusting frame 13, thereby adjusting the position of the scraper 12 to the back roller 7. The drive component 2 is located on the side of the adjusting frame 13 away from the scraper holder 11 and is connected to the adjusting frame 13. The drive component 2 is used to drive the entire scraper assembly 1 to move. By controlling the movement of the adjusting frame 13 through the drive and fine-tuning the position of the scraper 12 through the fine-tuning component 3, the distance between the scraper 12 and the object to be cleaned can be accurately controlled, ensuring that the scraper 12 works in the best contact state, reducing the friction between the scraper 12 and the object surface, avoiding damage, and extending the service life.

[0039] The fine-tuning component 3 includes two sets of screws 31 and a knob 32. In this embodiment, the two sets of screws 31 are respectively installed on both sides of the adjustment frame 13 to optimize the spatial layout and facilitate the implementation of fine-tuning operations. One end of the screw 31 passes through the adjustment frame 13 and is connected to the scraper frame 11. The other end of the screw 31 is connected to the knob 32. The knob 32 is located on the side of the adjustment frame 13 away from the scraper frame 11. A nut 33 is threaded onto the screw 31. The nut 33 abuts against the side of the adjustment frame 13 near the scraper frame 11.

[0040] By rotating the knob 32, the screw 31 undergoes a slight axial displacement, thereby adjusting the position of the scraper 12. When the knob 32 is rotated, the screw 31 moves along the thread direction to achieve the purpose of fine adjustment. The operator only needs to loosen the nut 33 and rotate the knob 32 to complete the fine adjustment operation. No special tools are required, making it easy to operate.

[0041] The driving component 2 is located on the side of the adjusting frame 13 away from the scraper frame 11. The driving component 2 includes a bracket 23 and a cylinder 21 mounted on the bracket 23. The telescopic rod 22 of the cylinder 21 is connected to the adjusting frame 13. Through the telescopic movement of the cylinder 21, the adjusting frame 13 can move within a large range, driving the scraper frame 11 and the scraper 12 to move back and forth. The cylinder 21, as the driving method, has a fast response speed and can complete a large displacement in a short time, with high efficiency and reliability.

[0042] In this embodiment, a control unit is also included. The control unit is electrically connected to the cylinder 21 and the motor 71 that drives the back roller 7 to rotate. The control unit can drive the cylinder 21 and the motor 71 to work at the same time, that is, it can drive the scraper assembly 1 and the back roller 7 to move synchronously.

[0043] The cleaning device also includes a scale marking structure 6, which is arranged along the moving direction of the scraper 12. In this embodiment, the scale marking structure 6 can be mounted on the bracket 23 and extends along the moving direction of the scraper 12 to indicate the moving position of the scraper 12. Through the scale marking structure 6, the operator can quickly determine the position of the scraper 12, ensure that the error is reduced during the fine adjustment process, and provide a clear standard reference for subsequent operations.

[0044] In actual cleaning work, first start cylinder 21. The telescopic rod 22 of cylinder 21 extends to drive the adjustment frame 13 to move closer to the back roller 7, which drives the scraper frame 11 and scraper 12 to move closer to the back roller 7, completing a large displacement, so that the scraper 12 is roughly close to the surface of the object to be cleaned. Then stop the operation of cylinder 21 and enter fine adjustment work.

[0045] The position of the scraper 12 is finely adjusted by the fine-tuning component 3. First, loosen the nut 33, and then drive the screw 31 to move by rotating the knob 32. The screw 31 drives the scraper holder 11 and the scraper 12 to move until the scraper 12 reaches the optimal contact state with the object to be cleaned. During this process, the accurate position of the scraper 12 can be checked by the scale marking structure 6, so that the operator can quickly judge the current position of the scraper 12 and ensure the accuracy of the fine-tuning operation.

[0046] In this embodiment, to ensure that the pressure applied by the scraper 12 to the back roller 7 is within a preset range and to avoid equipment damage or poor cleaning effect due to excessive or insufficient pressure, the cleaning device also includes a pressure sensor and an alarm system (not shown in the figure). The pressure sensor is located on the back roller 7 and is used to monitor the pressure applied by the scraper 12 to the back roller 7 in real time and transmit the pressure data to the alarm unit. When the monitored pressure value exceeds the preset range, the alarm unit issues an alarm to prompt the operator to adjust the cleaning status in time. This design can ensure the safety and stability of operation and prevent equipment damage or poor cleaning effect due to operational errors.

[0047] The dust collection assembly 4 includes a dust collection box 41 and a negative pressure adsorption structure (not shown in the figure) disposed in the dust collection box 41. The dust collection box 41 is located below the scraper 12 and is used to collect the impurities removed by the scraper 12. The negative pressure adsorption structure is a centrifugal fan or a vacuum pump, which is used to create a negative pressure environment inside the dust collection box 41, thereby effectively adsorbing and collecting the impurities scraped off by the scraper 12 and preventing the impurities from scattering.

[0048] During operation, the dust collection component 4 uses negative pressure adsorption to draw impurities into the dust collection box 41, reducing the spread of waste in the working environment, maintaining the cleanliness of the production environment, thereby effectively improving the waste collection efficiency, avoiding the waste of manual cleaning time, and ensuring the efficient operation of the equipment.

[0049] The implementation principle of this application embodiment is as follows: During the cleaning process, the operator only needs to start the cylinder 21. The telescopic rod 22 of the cylinder 21 extends to drive the adjustment frame 13 to move, which in turn drives the scraper frame 11 and the scraper 12 to move closer to the back roller 7, completing a large displacement, so that the scraper 12 is approximately close to the surface of the object to be cleaned, and then the operation of the cylinder 21 is stopped, and fine-tuning is started.

[0050] The position of the scraper 12 is finely adjusted by the fine-tuning component 3. First, loosen the nut 33, and then drive the screw 31 to move by rotating the knob 32. The screw 31 drives the scraper holder 11 and the scraper 12 to move until the scraper 12 reaches the optimal contact state with the object to be cleaned. During this process, the accurate position of the scraper 12 can be checked by the scale marking structure 6, so that the operator can quickly judge the current position of the scraper 12 and ensure the accuracy of the fine-tuning operation. During the cleaning process, the impurities scraped off by the scraper 12 are sucked into the dust collection box 41 by the negative pressure adsorption structure, keeping the working environment clean.

[0051] During this process, the pressure sensor monitors the pressure applied by the scraper 12 to the back roller 7 in real time and transmits the pressure data to the alarm unit; when the monitored pressure value exceeds the preset range, the alarm unit issues an alarm to prompt the operator to adjust the cleaning status in time.

[0052] This application improves the cleaning efficiency and quality of the back roller 7 by accurately controlling the distance between the scraper 12 and the back roller 7. Through the synergistic action of the drive component 2, the fine-tuning component 3, and the dust collection component 4, it ensures that the scraper 12 can clean the back roller 7 under optimal contact conditions, while avoiding the re-accumulation or diffusion of impurities and maintaining a clean production environment. In addition, the design of the pressure sensor and alarm system further ensures the safety of the equipment, preventing equipment damage or poor cleaning effect due to abnormal pressure. This device has high cleaning efficiency, stability, and reliability, and can reduce manual cleaning costs while ensuring efficient cleaning. It effectively improves the problem of the accumulation of foreign matter on the back roller 7 that cannot be removed in time in the prior art, thereby ensuring the smooth progress of the lithium battery coating process and the stability of electrode quality, and improving production quality and efficiency.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
