20 世紀(jì)，隨著新能源產(chǎn)業(yè)的飛速發(fā)展，動力電池的商業(yè)應(yīng)用需求迅速增長，在應(yīng)用過程出現(xiàn)了一些正負(fù)極活性材料脫膜導(dǎo)致電池失效的案例，為了解決活性材料與箔材之間發(fā)生脫膜失效，企業(yè)逐步開始引入凹版印刷工藝（又稱凹版印刷、凹版涂布），以此來增加基材與極性材料的黏結(jié)力，從而提升電池的性能和產(chǎn)品安全。 

　　In the 20th century, with the rapid development of the new energy industry, the demand for commercial applications of power batteries has grown rapidly. In the application process, there have been some cases of positive and negative electrode active material delamination leading to battery failure. In order to solve the problem of delamination failure between active materials and foil materials, enterprises have gradually introduced gravure printing technology (also known as gravure printing or gravure coating) to increase the adhesion between the substrate and polar materials, thereby improving the performance and product safety of batteries. 

　　凹版印刷工藝在動力電池制造中的應(yīng)用主要體現(xiàn)在鋰離子電池電極的制造上。?凹版印刷能夠精確控制電極材料的涂布厚度和均勻性?，這對于電池的容量、充放電性能和循環(huán)壽命有著至關(guān)重要的影響。例如，凹版印刷機(jī)可以將活性物質(zhì)如鈷酸鋰、磷酸鐵鋰等與導(dǎo)電劑、粘結(jié)劑均勻混合后，印刷在集流體上，形成厚度精確、性能穩(wěn)定的正極極片。

　　The application of gravure printing technology in the manufacturing of power batteries is mainly reflected in the manufacturing of lithium-ion battery electrodes. Can gravure printing accurately control the coating thickness and uniformity of electrode materials? This has a crucial impact on the capacity, charge and discharge performance, and cycle life of batteries. For example, gravure printing machines can uniformly mix active materials such as lithium cobalt oxide and lithium iron phosphate with conductive agents and binders, and print them on current collectors to form positive electrode sheets with precise thickness and stable performance.

　　鋰電池生產(chǎn)里，凹版輥?zhàn)鳛橥坎辑h(huán)節(jié)的核心部件，其清潔度直接決定極片涂布質(zhì)量與電池性能。若輥面殘留油墨、雜質(zhì)，不僅會導(dǎo)致涂布不均，甚至可能引發(fā)電池短路風(fēng)險；臟污還會迫使產(chǎn)線頻繁換輥，拖慢生產(chǎn)節(jié)奏。因此，凹版輥清潔必須同時滿足微米級污垢清除、保護(hù)輥面鍍層與精度、適配產(chǎn)線效率三個核心需求。這時候，超聲波清洗的 “空化效應(yīng)”，成了打破困局的關(guān)鍵。

　　In the production of lithium batteries, the intaglio roller is the core component of the coating process, and its cleanliness directly determines the quality of electrode coating and battery performance. If there are residual ink and impurities on the roller surface, it will not only cause uneven coating, but may even pose a risk of battery short circuit; Dirt will also force the production line to frequently change rollers, slowing down the production pace. Therefore, the cleaning of gravure rollers must simultaneously meet the three core requirements of micron scale dirt removal, protection of roller surface coating and accuracy, and adaptation to production line efficiency. At this point, the cavitation effect of ultrasonic cleaning becomes the key to breaking the impasse.

　　超聲波清洗的“空化效應(yīng)是指高頻聲波在液體里激發(fā)無數(shù)小氣泡，氣泡爆破瞬間能釋放上千大氣壓的沖擊力，把輥面污垢震掉：可同時清洗版輥上網(wǎng)穴墨皮、涂料、膠料、灰塵、水珠等，既洗得干凈，又不會傷輥面鍍層和紋路精度。

　　The cavitation effect of ultrasonic cleaning refers to the high-frequency sound waves that excite countless small bubbles in the liquid. The burst of the bubbles can release an impact force of thousands of atmospheres, shaking off the dirt on the roller surface. It can also clean the ink, paint, rubber, dust, water droplets, etc. on the roller mesh holes at the same time. It can be cleaned thoroughly without damaging the coating and texture accuracy of the roller surface.

　　針對寬幅凹版印刷機(jī)版輥清洗需求，科爾推出凹版輥超聲波清洗解決方案，將版輥固定、清洗、漂洗、吹干等功能模塊集成一體，適配單工位使用，便于與印刷機(jī)產(chǎn)線集成，助力凹版印刷產(chǎn)線解決版輥清潔難題。

　　In response to the cleaning needs of the plate rollers in wide gravure printing machines, Kohl has launched an ultrasonic cleaning solution for gravure rollers, which integrates functional modules such as plate roller fixation, cleaning, rinsing, and drying, suitable for single station use, easy to integrate with printing machine production lines, and helps solve the problem of plate roller cleaning in gravure printing production lines.

　　方案采用版輥固定支架與夾頭提供剛性支撐，避免清洗時輥面晃動，保障清潔均勻性；高頻聲波啟動后，空化效應(yīng)持續(xù)剝離污垢，覆蓋所有細(xì)微紋路；清洗液排出后，設(shè)備自動切換清水噴淋，沖凈殘留清洗劑；最后壓縮空氣風(fēng)刀啟動，快速吹掃輥面實(shí)現(xiàn)干燥，還能防止氧化銹蝕。整個過程由電控系統(tǒng)統(tǒng)籌，帶動輥面勻速轉(zhuǎn)動，360°無死角清潔，全程無需人工干預(yù)，單輥清洗時間≤30min。

　　The scheme adopts a plate roller fixed bracket and clamp to provide rigid support, avoiding the shaking of the roller surface during cleaning and ensuring uniform cleaning; After the high-frequency sound wave is activated, the cavitation effect continues to peel off dirt and cover all fine patterns; After the cleaning solution is discharged, the equipment automatically switches to clean water spraying to flush out residual cleaning agents; Finally, the compressed air blower is activated to quickly blow and dry the roller surface, while also preventing oxidation and corrosion. The entire process is coordinated by the electronic control system, which drives the roller surface to rotate at a constant speed and clean 360 ° without dead corners. There is no need for manual intervention throughout the entire process, and the cleaning time for a single roller is ≤ 30 minutes.

　　方案核心的超聲波發(fā)生系統(tǒng)，具備高頻率、高功率密度特性，可高效剝離版輥表面油墨、雜質(zhì)；清洗參數(shù)靈活可調(diào)，適配不同臟污程度、材質(zhì)版輥清洗，高效清潔不損傷版輥基體，保障后續(xù)印刷質(zhì)量。

　　The ultrasonic generation system at the core of the solution has high frequency and high power density characteristics, which can efficiently peel off ink and impurities on the surface of the plate roller; The cleaning parameters are flexible and adjustable, suitable for different degrees of dirt and materials of plate roller cleaning, efficient cleaning without damaging the plate roller substrate, ensuring subsequent printing quality.

　　同時，方案配置PLC控制系統(tǒng)，實(shí)現(xiàn)版輥推送、清洗液注入排出、漂洗水噴淋及吹干等動作的自動化流程。在實(shí)際應(yīng)用中，可穩(wěn)定配合產(chǎn)線節(jié)奏，簡化人工操作，提升版輥周轉(zhuǎn)效率。此外，方案采用水循環(huán)及回收設(shè)計，減少清洗液浪費(fèi)；無需大量化學(xué)溶劑（或降低溶劑使用量），降低對環(huán)境的污染，符合綠色工業(yè)生產(chǎn)要求，保障操作工人健康與工作環(huán)境安全。

　　At the same time, the scheme is equipped with a PLC control system to achieve automated processes such as plate roller pushing, cleaning solution injection and discharge, rinsing water spraying, and drying. In practical applications, it can stably coordinate with the production line rhythm, simplify manual operations, and improve the turnover efficiency of plate rollers. In addition, the plan adopts water circulation and recycling design to reduce the waste of cleaning solution; No need for a large amount of chemical solvents (or reducing solvent usage), reducing environmental pollution, meeting the requirements of green industrial production, and ensuring the health and safety of workers and the working environment.
