Revolutionize Small Cylindrical Battery Manufacturing with Automation

As demand for electric tools, portable energy storage, and smart home devices grows,

 small cylindrical batteries (18650, 21700, 26650) are at the forefront of innovation.

 Guangdong Songke’s New Energy Small Cylindrical Battery Pack Production Line 

offers end-to-end automation for high-consistency, high-efficiency production.

Core Processes & Technical Highlights

Process Key Features

Automatic Feeding Compatible with 18650/21700/26650 batteries; ±0.5mm 

precision positioning via vibratory bowl + robotic arm.

CCD Polarity Detection Vision system inspects electrode

 orientation with ±0.02mm accuracy; automatically rejects defects.

Laser Welding & Spot Welding Welding resistance <2mΩ; 

bonding strength ≥80N; eliminates cold soldering risks.

Modular Pack Assembly Automated bracket locking, busbar welding, 

and insulation film wrapping; cycle time as low as 15 seconds/piece.

Safety Protocols Explosion-proof design + smoke alarm system; compliant with CE/UL safety standards.

5 Core Advantages Over Traditional Lines

Flexibility for Diverse Formats

Supports battery diameters 18–26mm and lengths 14–35mm; 

rapid customization for high-capacity models (e.g., 26650).

Full Automation, Lower Costs

Reduces manual labor by 60%; daily output up to 5,000pcs with yield ≥99.5%.

Data-Driven Quality Control

Barcode scanning + MES system tracks voltage, internal resistance, 

and position; meets IATF 16949 traceability requirements.

Scalable Architecture

Expandable with pack testing (e.g., charge/discharge, thermal runaway) and AGV logistics integration.

Sustainable Production

Energy consumption reduced by 40%; certified under EU RoHS environmental standards.

Application Scenarios

✅ E-Bikes/E-Scooters: Lightweight packs for extended range

✅ Portable Energy Storage: Outdoor power stations, home backup systems

✅ Smart Devices: Drones, robotic vacuum cleaners, and IoT terminals

Customer Testimonial

“Our delivery cycles shortened by 40%, and customer complaints 

dropped 70% after adopting Songke’s production line!”
