Introduction

With the rapid development of electric vehicles (EVs) and energy storage systems, the demand for high-quality battery components has continued to increase. Aluminum battery covers, battery shells, and other structural parts require extremely high standards for material flatness, surface protection, feeding accuracy, and production efficiency.

To meet these manufacturing requirements, Coil Processing Equipment has become an essential solution for automated battery component stamping production.

YouYi Precision provides advanced Coil Processing Equipment for new energy battery components, integrating automatic decoiling, precision leveling, servo feeding, and stamping automation technologies. The complete system helps EV battery manufacturers achieve stable, efficient, and continuous aluminum coil processing from raw material to finished stamped components.

Challenges of Aluminum Coil Processing for EV Battery Components

In new energy battery manufacturing, aluminum materials are widely used because of their lightweight properties, corrosion resistance, and excellent forming performance. However, aluminum coil stamping also creates higher requirements for production equipment.

During battery shell and cover stamping, manufacturers need to solve several challenges:

1. High Requirements for Material Flatness

Uneven aluminum coils may cause unstable feeding, forming defects, and dimensional inconsistencies during stamping.

A high-precision leveling process is essential to remove coil stress and ensure smooth material feeding.

2. Protection of Aluminum Surface Quality

Battery aluminum shells usually require strict surface quality control. Scratches, dents, or pressure marks during coil processing may affect the appearance and performance of final battery components.

Therefore, the coil processing system must provide stable material handling and precise leveling without damaging the aluminum surface.

3. Continuous High-Speed Production

With increasing demand for EV batteries and energy storage systems, manufacturers require automated production lines that can reduce manual operations and improve production efficiency.

A complete EV Battery Stamping Equipment solution helps achieve continuous coil-to-part manufacturing.

Complete Coil Processing Equipment Solution for Battery Aluminum Shell Stamping

To meet the production requirements of new energy battery components, YouYi Precision developed a complete HTC-1600 Coil Processing Equipment consisting of:

· 15-ton automatic decoiler

· Precision straightener leveler

· Servo feeder

· High-speed stamping press

The complete system realizes automatic processing from coil loading, decoiling, leveling, feeding, to stamping forming.

15-Ton Automatic Decoiler for Stable Heavy Coil Unwinding

The front-end of the production line adopts a large automatic decoiler designed for heavy aluminum coil processing.

It can handle aluminum coils up to 15 tons, meeting the requirements of wide and heavy coil materials used in new energy battery production.

The equipment is equipped with:

· Loading cart

· Pressure arm

· Supporting arm

These designs ensure safer coil loading and stable unwinding operation.

The main shaft adopts a hydraulic expansion structure, which improves coil clamping stability and effectively reduces problems such as coil loosening and material deviation during operation.

Stable decoiling provides a reliable foundation for subsequent precision leveling and feeding processes.

Precision Straightener Leveler Improves Aluminum Material Quality

For battery aluminum shell stamping, material flatness directly affects product accuracy and forming quality.

The Coil Processing Equipment is equipped with a precision coil straightener featuring a flip-open leveling head design.

Key advantages include:

· Stable leveling adjustment

· Easy maintenance

· Reduced aluminum surface damage

· Improved material flatness

The straightener uses 11 precision leveling rollers and is suitable for aluminum materials with:

· Material width: 100-1600mm

· Material thickness: 1.0-2.06mm

The flip-open structure allows operators to easily clean aluminum powder and impurities inside the rollers, reducing scratches and pressure marks during processing.

This design is especially suitable for high-quality aluminum shell and battery cover stamping applications.

Servo Feeding System Ensures High-Precision Continuous Stamping

The feeding system is equipped with a servo roll feeder combined with servo motor drive and PLC control technology.

During EV battery stamping production, feeding accuracy directly affects:

· Product dimensional consistency

· Material utilization

· Stamping stability

The servo feeding system provides:

· Accurate feeding control

· Synchronized operation with stamping presses

· Reduced material waste

· Stable continuous production

A transition bridge is installed between the straightener and servo feeder, enabling automatic material transfer without manual lifting, improving automation efficiency and reducing labor requirements.

Advantages of Coil Processing Equipment for New Energy Battery Manufacturing

Compared with traditional single-machine processing methods, an integrated Aluminum Coil Processing Equipment provides significant advantages:
