I. Core Functions: Full-Process Automation and High-Precision Control

圓柱鋰電池自動(dòng)包塑機是鋰電廠(chǎng)實(shí)現高效生產(chǎn)、保障產(chǎn)品質(zhì)量的核心設備，其核心功能體現在以下三方面：

Automatic plastic wrapping machines for cylindrical lithium batteries are core equipment for lithium battery factories to achieve efficient production and ensure product quality. Their core functions are reflected in the following three aspects:

全流程自動(dòng)化生產(chǎn)

Full-Process Automated Production

設備整合了包塑、封口、PACK組裝等工序，實(shí)現從電芯到成品電池包的連續生產(chǎn)。以中步擎天CTC-80S系列為例，其采用集成PLC、傳感器、步進(jìn)電機等自動(dòng)化技術(shù)，支持多型號電芯（如18650、21700）快速切換，兼容性覆蓋動(dòng)力電池、儲能電池等主流需求。設備節拍可達800PC/H（單工序），若整合全流程，單線(xiàn)日產(chǎn)能可突破1.9萬(wàn)支（按8小時(shí)計算），顯著(zhù)減少人工干預。

The equipment integrates processes such as plastic wrapping, sealing, and PACK assembly to achieve continuous production from cells to finished battery packs. Taking the Zhongbu Qingtian CTC-80S series as an example, it uses integrated automation technologies such as PLC, sensors, and stepper motors, supports rapid switching between multiple cell models (e.g., 18650, 21700), and its compatibility covers mainstream demands like power batteries and energy storage batteries. The equipment cycle time can reach 800 PC/H (single process). If the entire process is integrated, the daily capacity of a single line can exceed 19,000 units (calculated based on 8 hours), significantly reducing manual intervention.

包塑機通過(guò)伺服電機精準控制包塑厚度，結合在線(xiàn)測厚系統實(shí)時(shí)反饋數據，確保每顆電池的包塑層厚度偏差≤±0.02mm。例如，某頭部電池廠(chǎng)引入該設備后，電池包塑層一致性提升40%，因材料浪費導致的成本降低15%。

The wrapping machine precisely controls the wrapping thickness through servo motors, combined with real-time data feedback from an online thickness measurement system, ensuring the wrapping layer thickness deviation of each battery is ≤±0.02mm.
