I. Introduction



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.

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.

6. Deviation correction control


It is composed of electrode and separator unwinding deviation correction, electrode's process deviation and pre winding deviation correction.


The deviation correction mechanism is composed of a detection element and an actuator. The photoelectric sensor is used to detect the reference edge of the electrode to determine whether the electrode is offset, and the deviation correction roller is controlled to swing back and forth or move to correct the deviation. The error correction status is displayed on the man-machine interface.


A. Unwinding deviation correction: the unwinding material shaft (material coil synchronization) and the deviation correction swing rod are used for synchronous overall deviation correction to ensure that the position of the unwinding electrode and separator is stable and within the allowable range.


B. Process deviation correction: at the position before feeding, the deviation correction roller swings back and forth to further ensure the accuracy of the electrode to the feeding position.


C. Correction before winding: under the electrode cutter, before winding (very close to the winding needle). Ensure that the alignment of the rolled out cell is within the range when the electrode enters the cell
