Louis@lithmachine.comSemi-Auto Lithium-Ion Battery Winding Machine for Prismatic Cells
1. Equipment Function Description
This machine is mainly used for the precise winding of prismatic lithium-ion battery cells.
The working process is as follows: the operator manually inserts the cathode and anode sheets into the winding unit, interleaves them with the separator, and winds according to the process requirements. The machine then automatically applies the termination tape and discharges the wound cell.
2. Equipment Functions and Features
1. Adopts dual winding needle structure.
2. Manual electrode loading – automatic winding – automatic needle change – automatic tape application – automatic cell discharge.
3. Termination tape is applied longitudinally (parallel to the tabs); the tape is applied smoothly with precise control, without pulling the cell; tape application is stable and reliable.
4. Winding needle speed is adjustable.
5. Two separator rolls with active unwinding; tension controlled via encoder feedback and high-precision proportional air valve to maintain constant tension; tension can be smoothly adjusted during winding.
(Tension control as shown in diagram:)
6. Equipped with electrode dust removal device.
7. Cell tail wrapping can be performed with electrode or separator.
8. The wound cell is free of damage, core pulling, or electrode misalignment.
9. Easy operation; size and specification adjustments are simple and quick.
3. Process Flow
This machine conforms to the standard winding process for prismatic lithium-ion batteries: the separator fully wraps the anode, and the anode wraps the cathode.
Process steps:
1. Separator pre-winding: uses heated welding with serrated blade to cut separator, reducing pre-wound length, avoiding separator stringing and surface marks on cells.
2. Insert anode: manually insert the anode sheet into the winding section.
3. Insert cathode: manually insert the cathode sheet into the winding section.
4. Winding.
5. Indexing rotation for station change.
6. Separator cutting, tape application, and cell discharge.
4. Equipment Structure
This equipment is made up of a winding unit, indexing unit, separator unwinding unit, electrode guiding unit, tape application unit, cell discharge unit, and control system.
Winding Unit (2 sets): It is equipped with offset winding needles to guarantee winding precision, and the winding needles can be replaced effortlessly.
Indexing Unit (1 set): It is used for switching between the winding station and the tape application station through indexing rotation.
Separator Unwinding Unit (2 sets): It adopts active unwinding, with tension adjusted and controlled by pneumatic means.
Electrode Guiding Unit (2 sets): It features single-side adjustment, making operation simple and convenient.
Tape Application & Discharge Unit (1 set).
