Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode production equipment technology, and in particular to a stretching and wrinkle removal device based on electrode production. Background Technology
[0002] In the production of lithium batteries, capacitors, and other products, electrodes are a crucial component, and their quality directly affects the product's performance and lifespan. During electrode production, after processes such as coating and drying, wrinkles are prone to appearing. These wrinkles lead to uneven electrode thickness and surface roughness, affecting not only the electrode's appearance but also causing problems in subsequent winding and assembly processes, reducing product yield and increasing production costs.
[0003] Existing stretching and wrinkle removal devices based on electrode production suffer from uneven stretching force adjustment, which can easily lead to localized overstretching or understretching of the electrode, failing to completely eliminate wrinkles. Temperature control during wrinkle removal is inaccurate; excessively high temperatures can damage the electrode coating, while excessively low temperatures result in poor wrinkle removal. The lack of a flattening structure that coordinates with stretching and wrinkle removal makes it easy for wrinkles to reappear after removal. Furthermore, the devices have poor adaptability to electrode thicknesses, requiring frequent component replacements and impacting production efficiency. Debris is easily generated during electrode transport, and its accumulation can scratch the electrode surface. Utility Model Content

[0036] The effects achieved by the above components are as follows: by setting the rubber head 49 to slide in contact with the lower flattening roller 45, it is ensured that the roller surface debris is fully scraped off; the inclination of the scraper 48 guides the scraped debris to slide down to the debris opening, avoiding debris scattering; the debris opening provides a channel for the debris to enter the collection box, ensuring that the debris is collected in a concentrated manner; the feeding rack 5 guides the electrode sheet to be processed to accurately enter the stretching assembly 2, and the receiving rack 6 collects the electrode sheet that has completed stretching, wrinkle removal and flattening, realizing continuous operation of electrode sheet production and improving production efficiency.
[0037] Working principle: By setting up a stretching component 2 and a wrinkle removal component 3, the hydraulic actuator 22 of the stretching component 2 drives the adjusting frame 23 to rise and fall along the guide rod 27, adjusting the spacing of the stretching rollers 26 to adapt to electrode sheets of different thicknesses. The displacement sensor 24 monitors the position of the adjusting frame 23 to ensure accurate spacing of the stretching rollers 26. The motor A 25 drives the stretching rollers 26 to rotate, uniformly stretching the electrode sheet and eliminating wrinkles, solving the problem of uneven stretching in existing devices. Inside the heating box 34 of the wrinkle removal component 3, the heating wire 36 heats up, causing the heating tube 35 to generate heat, which heats and removes wrinkles from the stretched electrode sheet. The temperature sensor 37 monitors the temperature inside the heating box 34 in real time, and the temperature control board 38 adjusts the temperature to avoid excessively high temperatures damaging the electrode sheet or excessively low temperatures affecting the wrinkle removal effect. The frame 33 slides along the limiting groove 32 to adjust the position of the heating box 34, ensuring that the electrode sheet is fully heated and improving the wrinkle removal effect. The telescopic device 42 of the flattening structure 4 drives the lifting frame 43 to rise and fall along the positioning rod 44, adjusting the spacing of the flattening rollers 45 to flatten the wrinkled electrode sheet and prevent wrinkles from forming again. Motor B 46 drives the flattening rollers 45 to rotate, assisting in the electrode sheet conveying. The rubber head 49 of the scraper 48 slides along the flattening rollers 45 to clean the roller surface debris. The debris falls into the debris collection box 47 through the debris port to avoid scratching the electrode sheet.
