Automatic Lithium Polymer Battery Electrode Winding Machine For Pouch Cell

1. Device function description

This machine is mainly used for precision winding of square lithium ion battery cells. The working process is as follows: Manually introduce the cathode and anode plates into the winding part, separate from the separator, winding according to the process requirements, automatically attach the termination tape, and automatically discharge the battery.

2. Equipment features and function

2.1 Double-needle structure

2.2 Manual introduction of electrode sheet, automatic winding, automatic needle changing, automatic end tape and automatic discharging.

2.3 The tape is longitudinally glued (the end tape is parallel to the Tab), the glue is flat, the glue position can be precisely controlled and the battery core is not tightened; the glue is stable and reliable

2.3 Needle winding speed is adjustable

2.4 Two-volume separator active unwinding, encoder speed control technology, high-precision air proportional valve control constant tension, can automatically adjust the tension smoothly during the winding process; (tension control as shown

2.5 With electrode dust removal device

2.6 Electrode outsourcing or separator outsourcing

2.7 The coiled battery has no damage, core pulling and electrode misalignment

2.8 Easy to operate, easy to adjust and change specifications

3. Specification

3.1 Width for separator: 25-100MM Needle: 15-60mm electrode width: 23-98mm

3.2 Material specification requirements (unit: mm)

3.3 Ability: 5~10 pcs/min (depending on the width of the needle, the length/width of the pole piece)

3.4 Winding accuracy

When ensuring that the electrode meets the following conditions:

The width error of the electrode is less than ±0.2mm
