Automatic Sticker Pasting Machine – 18700 & 21700 / 26700 / 32700 / 33140

A compact and efficient automatic sticker pasting machine designed for cylindrical lithium batteries, enabling fast and consistent barley paper application across multiple cell sizes with low noise and high reliability.

Technical Excellence

Automatic Sticker Pasting Machine – Cylindrical Cells (18700 to 33140)

The Automatic Sticker Pasting Machine for 18700–33140 cylindrical cells is a dedicated solution for applying insulating barley paper to finished lithium batteries in preparation for assembly or welding. Supporting a wide range of cell specifications—including 18650, 18700, 21650, 21700, 26650, 26700, 32650, 32700, and 33140—this machine offers strong versatility for manufacturers handling multiple battery formats.

The system uses manual feeding and manual receiving, making it suitable for flexible production environments and pilot lines. At the sticker station, the machine processes four batteries at a time, significantly improving efficiency while maintaining consistent placement accuracy. A pneumatic cylinder-driven knife mechanism ensures smooth, repeatable barley paper pasting without damaging the battery surface.

Designed for stable long-term operation, the machine delivers a device failure rate below 2% and a product loss rate under 0.1%, while operating at a low noise level of 48 dB. Its compact footprint allows easy integration into existing production layouts, making it a practical and cost-effective solution for cylindrical battery insulation processes.
