1.Equipment Overview

This machine is used for winding cylindrical 18650 battery cells.

2.Operation Procedure

1. Manual feeding of positive and negative electrode sheets and separators

2. Dust removal of electrode sheets and static electricity removal of separators

3. Introduction to the winding section and winding according to process requirements

4. Affixing termination tape

5. Automatic unloading of finished products

3.Equipment Technical Parameters

Material Requirements

1. The width error of the electrode sheet is less than ±0.1mm;

2. The "S" bending error of the electrode sheet is less than 0.5mm/1000mm, and there should be no curling;

3. The tower shape error of the separator material roll is less than ±0.2mm, and there should be no curling.

4.Main Component Configuration

1. This equipment is composed of separator unwinding device, electrode sheet guiding device, winding device, workstation conversion device, gluing device, unloading device and control system, etc. The details are as follows:

2. Separator unwinding device (two sets): Composed of separator unwinding mechanism, tension control mechanism, transition wheel, etc.

3. Electrode sheet guiding device (two sets): Composed of guiding plates and electrode sheet dust removal device whose position and width can be adjusted as needed.

4. Gluing device (one set): Pneumatic clamping, pulling, cutting and transfer of tape, roller gluing.

5. Unloading device (one set): Receiving box (standard).

5.Equipment Features

1. Single winding needle structure is adopted, and the winding needle diameter can be replaced.

2. Manual introduction of electrode sheets, automatic winding, automatic termination tape sticking and automatic unloading.

3. The gluing position can be precisely controlled and the battery cell will not be tightened; gluing is stable and reliable.

4. The linear speed of the separator and electrode sheet feeding is relatively constant, which means that the constant tension is achieved during the winding process, ensuring that the battery cell is wound neatly and uniformly.

5. It has an electrode sheet dust removal device.

6. The wound battery cell is free of damage, core pulling and electrode sheet misalignment.

7. It has output statistics function.

8. The whole machine runs stably, the control is reliable and the operation is convenient.
