Fully Automatic Lithium Ion Battery Electrode Sheet Die Cutting Machine

Product Overview

This fully automatic die cutting system is engineered for forming power lithium battery electrode sheets produced by continuous coating processes. It combines automatic roll unwinding, electrode alignment, tab die cutting, CCD inspection, dust removal, dimensional checking, and automatic rewinding in one coordinated production platform. The result is a controlled, high-throughput process for converting coated roll material into accurately formed electrode sheets with tabs.

The equipment is suited to lithium ion battery electrode manufacturing lines where roll-to-roll material handling, repeatable geometry, low burr formation, and inspection coverage are operational priorities. It supports electrode sheet lengths from 150-500 mm, including the tab, and accommodates substantial feed rolls up to 750 mm outside diameter and 500 kg.

Built for continuous industrial operation, this unit combines a production speed of at least 35 m/min with a design speed of at least 45 m/min. Specified dimensional accuracy, rewinding consistency, mold durability, and a qualified-product rate of at least 99.5% help manufacturers maintain disciplined output under demanding production conditions.

Key Features

• Integrated Roll-to-Roll Processing: The equipment performs automatic unwinding, electrode correction, tab die cutting, inspection, dust removal, dimensional verification, and rewinding in a single process flow. This integrated arrangement supports efficient handling of continuously coated electrode rolls.

• Automatic Electrode Alignment: Built-in correction capability manages the position of the roll electrode sheet before tab forming. Stable material tracking is essential for maintaining the specified electrode geometry through the cutting and rewinding sequence.

• Tab Die Cutting Capability: This system is configured for electrode tab forming on roll electrode sheets used in power lithium battery production. It supports finished electrode lengths of 150-500 mm, with the tab included in the stated dimension.

• CCD Defect Inspection: CCD inspection is incorporated to identify defects during processing. In-line visual inspection supports closer process oversight while material remains in the continuous production path.

• CCD Dimensional Detection: The equipment also uses CCD-based size inspection to verify electrode dimensions. This inspection capability supports the specified electrode size accuracy of +/-0.2 mm and helps production teams monitor dimensional consistency.

• Controlled Burr Performance: The die cutting process is specified for longitudinal burrs of <=15 um and transverse burrs of <=10 um. These controlled limits address a critical electrode-processing concern where edge quality affects downstream cell assembly requirements.

• Long-Life Die Tooling: The mold is specified for more than 1 million cycles per use and more than 10 grinding operations. This durability supports sustained production use and provides a practical basis for managing tooling service intervals.

• High-Speed Production Design: Production speed is specified at >=35 m/min, with a design target of >=45 m/min. The system is therefore positioned for continuous electrode conversion operations that require both throughput and controlled processing.

• Orderly Automatic Rewinding: Automatic rewinding is included after the cutting and inspection stages, with rewinding neatness specified at +/-1 mm. This supports organized material collection and helps preserve usable roll condition for subsequent handling.

• Industrial Utility Configuration: The unit operates from AC380V+/-5%, three-phase 50Hz power and requires compressed air at 0.5-0.6Mpa. Its defined power and air-consumption requirements allow facilities to assess installation readiness before deployment.

Why Choose This Product

• Production-Focused Process Integration: This system brings unwinding, correction, tab forming, dual CCD inspection functions, dust removal, and rewinding into one equipment platform. The defined process scope helps manufacturers evaluate a complete electrode forming sequence rather than separate isolated operations.

• Precision for Electrode Geometry: A specified electrode sheet dimensional accuracy of +/-0.2 mm, combined with CCD dimensional detection, supports controlled formation of electrode sheets and tabs. The stated 150-500 mm electrode length range gives production teams a clear operating envelope.

• Edge-Quality Performance: Specified longitudinal and transverse burr limits address a core requirement in electrode sheet processing. Controlled burr performance helps focus attention on the quality of the cut edge as well as the final electrode dimensions.

• Durability for Continuous Operation: Mold life of more than 1 million cycles per use and more than 10 grinding operations reflects a design intended for repeated industrial processing. The specified production speed, qualified-product rate, and equipment failure rate provide measurable reference points for operational consistency.

• Installation-Ready Operating Data: Defined electrical supply, starting and operating power, compressed-air requirements, dimensions, ambient temperature range, and roll capacity enable procurement and engineering teams to assess facility compatibility with greater confidence.
