Semi-Automatic Prismatic Cell Electrode Winding Machine
1. Equipment Function Description
This machine is primarily designed for the precision winding of prismatic lithium-ion battery cells.
The operational process is as follows: the operator manually loads cathode and anode sheets into the winding unit, places separators between them, and winds them as per the process specifications. After that, the machine automatically attaches the termination tape and ejects 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 equipment complies with the standard winding process for prismatic lithium-ion batteries, which specifies that the separator must fully enclose the anode, and the anode must wrap around the cathode.
Process steps:
1. Separator pre-winding: A serrated blade is used in conjunction with heated welding to cut the separator, shortening the pre-wound length. This prevents separator misalignment and surface scratches on the cells.
2. Anode insertion: Manually place the anode sheet into the winding section.
3. Cathode insertion: Manually place the cathode sheet into the winding section.
4. Perform winding.
5. Indexing rotation to switch stations.
6. Separator cutting, tape application, and cell ejection.
4. Equipment Structure
1. This equipment is composed of the winding unit, indexing unit, separator unwinding unit, electrode guiding unit, tape application unit, cell discharge unit, and control system.
2. Winding Unit (2 sets): consists of offset winding needles to ensure winding accuracy; winding needles are easy to replace.
3. Indexing Unit (1 set): for switching between winding and tape application stations.
4. Separator Unwinding Unit (2 sets): active unwinding with pneumatic tension adjustment control.
5. Electrode Guiding Unit (2 sets): single-side adjustment, easy to operate.
6. Tape Application & Discharge Unit (1 set).
