Semi-Automatic Cylindrical Battery Winding Machine



1.Equipment Function Description:

This machine is mainly used for precision winding of cylindrical lithium ion battery cells.

 

The working process is as follows: manually guide the positive and negative plates into the winding part respectively, stack them with the diaphragm, wind them according to the process requirements, automatically attach the termination tape, and the cell is automatically cut.

 

2.Equipment Functions and Features:

1) Single target threading needle structure is adopted.

2) Manual introduction of pole piece, automatic winding, automatic needle change, automatic pasting of termination tape and automatic blanking.

3) The adhesive tape is pasted horizontally (the termination tape is perpendicular to the pole ear), the adhesive tape is flat, and the adhesive position can be accurately controlled without straining the electric core; Glue sticking is stable and reliable.

4) The winding speed of winding needle is adjustable.

5) Active unwinding of two coil diaphragm, tension proximity switch control technology, which can automatically and smoothly adjust the tension in the winding process; The upper and lower tension can be adjusted.

6) Closure of diaphragm outsourcing.

7) The rolled out electric core shall be free of damage, core pulling and pole dislocation.

8) Easy operation, simple and fast adjustment and replacement of specifications.

 

3.Technological Process:

The equipment meets the winding process standard of cylindrical lithium-ion battery: the diaphragm completely wraps the negative sheet, and the negative sheet wraps the positive sheet. The process flow is as follows:

1) Diaphragm pre coiling: Adopting tooth cutter technology can save the length of pre coiling diaphragm;

2) Draw in the negative electrode: Manually guide the negative electrode sheet into the winding part;

Draw in the positive electrode: Manually guide the positive pole piece into the winding part;

3) Winding;

4) Shift station;

5) Cut off the diaphragm, paste the termination glue and blanking.

3) Applicable outer diameter of electric core (mm -20mm)

4) Equipment capacity: 5 ~ 10 pieces/min (according to pole piece length/width)

5) Winding accuracy;

 When ensuring that the pole piece meets the following conditions:

The width error of the pole piece is less than±0.2mm;

The "S" bending error of the pole piece is less than±1mm/500mm;

The tower shape error of diaphragm coil is less than±0.2mm;

The winding accuracy can meet: The diaphragm alignment error is less than±0.5mm; The alignment error of pole piece is less than±0.5mm;

It can realize the alignment of negative electrode wrapped with positive electrode and diaphragm wrapped with negative electrode, and the section of finished product is

±0.5mm.

6) Qualified rate: 98% (Excluding non equipment factors).
