Gelon Battery Equipment Cylinder cell lithium battery production line Auto-Semiauto winding machine

I. Introduction

Feature:

1. Full cam control is adopted for the pulling and pushing needle and reversing. The equipment is stable, with high efficiency and low failure rate.

2. The electrode adopts three-way deviation correction control: unwinding , process and pre-winding to ensure product quality.

The equipment winds the positive and negative electrode pieces and diaphragms of lithium-ion battery elements around the battery cells after passing through mechanisms such as dust removal, tension control, quality inspection, length measurement, traveling deviation correction, static electricity elimination, etc; After the completion of the production of the cell, the short-circuit test, defective discharge and transmission from the conveyor belt.

II.Specifications

1. Winding method:

A. 3 position winding with 3 winding needles.

B. Needle diameter Ø 3.5 (or customized (Ø 3.5 - Ø 8.0))

C. Winding diameter: Φ 18 - Φ 23mm (applicable to 18650, 21700, etc.)

D. Number of tabs: 1-2 for both cathode and anode, or all tabs

E. Exposed Tabs length: 8-25mm

2.Winding accuracy

A. Alignment of cathode and anode : ± 0.3mm

B. Alignment between electrode and separator: ± 0.3mm

Note: cathode and anode are corrected 3 times respectively (unwinding correction, process correction and pre-winding correction)

C.Alignment of two layers of separator: ± 0.5mm

3.Winding capacity

1. Production capacity

Production speed : ≥ 20 ppm within 1200mm long Anode; (21700 cells)

Crop mobilization rate ≥ 95%

mobilization rate = {total production / (startup time - necessary deduction time) × Theoretical production speed of equipment} × 100%, necessary deduction time: downtime caused by non equipment reasons, such as production preparation time for refueling and belt connection.

2. Qualification rate ≥ 98%

Qualification rate = total number of good products / (total production - necessary deduction) × 100%(except for poor materials)

It is necessary to deduct the quantity of defective products caused by non equipment factors, such as poor tape connection, out of tolerance of foil length, defective missing tabs, etc.

Tension of cathode and anode : 20N adjustable (settable)

Diaphragm tension: 10N adjustable (settable)

IV. Equipment installation and commissioning

1. Power supply: single phase AC220V ± 10% 50Hz

2. Air supply: 0.5-0.7mpa (when the air supply is 0.5MPa,

the required flow is 300NL / min)

3. Use environment (according to JISB3502)

A.Working temperature: 0-55 ℃

B. In the drying room, there must be no corrosive gas or combustible environment, and no harsh environment of dust

4. Dimension: 2850 X 2050 X 1800mm (Customized)

5. Color: silver (Customized)

6. Weight: About 3000kg (≤ 750KG / m2).

7. Power: 12KW

8.Noise: ≤ 75db (excluding dust suction fan)
