Product Description

I.Functional overview: 
    This machine is mainly used for precision winding of 21700 batteries. The working process is as follows: the positive and negative plates are manually introduced into the winding part, stacked with the separator, and wound according to the process requirements, the termination tape is automatically attached, and the battery core is automatically discharged.
II.Basic Parameters:
    1.Space:1500 mm(L)×1300mm(D)×1500mm(H);
2.Power:220 VAC±5,single phase,1 KW;
3.air source:5~7 kgf/cm²,100 l/min;
4.No corrosive gas,liquid,explosive gases
III.Technical parameters:

1. Diameter of Winding Needle:φ3.5mm or φ 4.0mm 
2. Separator width:40-70 mm;
3. Electrode width:38-68 mm;
4. Electrode length:400-1500 mm;
5. Tape width:30-80 mm;
6. Winding accuracy: separator and anode,anode and cathode electrode aligning, the error is less then±0.5 mm

Request for materials:
A,The error width for electrode is less then 0.1mm;
B,The electrode's "S" bending error is less then 0.5mm/1000mm,And there shall be no become warped edge phenomenon;
C,Separator materials tower error is less then±0.2mm,And there shall be no become warped edge phenomenon;

1. PCB equipment:6-10 PPM (Related to the length of the electrode and artificial feeding speed;

   IV Process performance
1. Adopt single winding needle structure, the diameter of the winding needle can be replaced.
2. Manual introduction of pole piece, automatic winding, automatic needle change, automatic tape termination and automatic blanking;
3. The glue application position can be accurately controlled without tightening the battery core; the glue application is stable and reliable;
4. The winding needle winding adopts the latest original variable-angle speed rotation technology, so that the linear velocity of the diaphragm and pole piece feed is relatively constant, that is, the purpose of constant tension during the winding process is achieved, and the winding of the battery core is neat and consistent.
5. The four-volume diaphragm is unwinding actively, and the diaphragm tension signal is detected in real time by the encoder connected to the tension swing arm shaft. After being processed by the PLC, the diaphragm unwinding stepper motor actively follows the tension change and changes the speed to unwind to achieve the diaphragm tension. Constant purpose. At the same time, supplemented by the  latest cylinder tension control technology, it can automatically and smoothly adjust the tension during the winding process.
6. The above-mentioned variable-angle speed winding technology, encoder detection tension diaphragm unwinding and variable speed following technology, auxiliary cylinder tension automatic adjustment technology, and the core deformation rate control are extremely low.
7. With pole piece dust removal device.
8. There is no damage to the rolled-out battery core, core pulling and dislocation of pole piece.
9. With output statistics function.
10. The whole machine runs stably, the control is reliable, and the operation is convenient.
