Semi Automatic 18650 Battery Cell Electrode Winding Machine



tob technology

1. Machine and function Description

This machine is mainly used for the precision winding of core of the cylinder battery.

The working process is as follows

Manually guide the cathode and anode electrodes into the winding part, and separated stacking with the separator, and the winding will be carried out according to the requirements of the process, automatically attaching the termination tape, and the cell will automatically feed.

2. Function and Features

2.1 Adopt single needle counter winding needle structure.

2.2 Manual lead-in electrode, automatic winding, automatic change needle, automatic tape ending tape and automatic unloading.

2.3 The adhesive tape adopts the horizontal paste (the tape is perpendicular to the tab), the adhesive is flat, and the adhesive position can be controlled accurately without tightening the cell, the adhesive is stable and reliable.

2.4 Winding needle speed was adjustable.

2.5 Two rolls of separator active to unwinding, tension push switch control technology can adjust tension automatically during winding.

2.6 It has a dust removal device

2.7 Separator outer pack end

2.8 The cell after winding without damage, core pulling and electrode dislocation phenomenon.

2.9 Easy to operate,adjust and replace.

3. Working Process

The machine meets the technical standard of the cylindrical lithium ion battery cell winding: the separator is completely wrapped the negative electrode, and the negative electrode is wrapped in the positive electrode.

The process flow is as follows

3.1 Separator pre winding: the length of pre winding separator can be saved by using the Tooth cutter technology.

3.2 Winding the negative electrode: manually lead in the negative electrode into the winding part; winding the positive electrode: manually lead in the positive electrode into the winding part;

3.3 Winding

3.4 Shift position

3.5 Cut off the separator, and stick termination tape and unloading.

4. Main Device

4.1 The machine consists of winding device, changing position device, separator unwinding device, electrode guide device, adhesive device, feeding device and control system.

4.2 Winding device (2 sets) : it is composed of single head to ensure the accuracy of winding, and it is convenient to replace the winding needle.

4.3 Shift position device (1 set) : for the conversion of winding station and adhesive position.

4.4 Separator releasing device (2 sets) : the separator roll material is active to release and air pressure regulating control.

4.5 Electrode guide device (2 sets) : unilateral adjustment, convenient adjustment.

4.6 Glue and feeding device (1 set).
