Product Overview
This manual lithium battery electrode sheet winding machine is designed to wind positive electrode sheets, negative electrode sheets, and separator material into finished cell cores. The equipment supports electrode winding for supercapacitors, cylindrical cells, and pouch lithium battery cells. Its adjustable material guide, winding support arrangement, and controlled rotation functions provide a practical platform for forming tightly wound cell structures in laboratory-scale cell fabrication work.
The unit is suited to battery research laboratories and development teams preparing flat or cylindrical electrode assemblies. Operators can set the guide channel to suit the electrode width, position the electrode leader at the winding needle, clamp it between the left and right needles, and use the foot valve to begin winding. The ability to change between round and square winding needle assemblies supports different cell formats within the stated dimensional limits.
Compact equipment dimensions, adjustable winding speed, and forward/reverse rotation make this system suitable where controlled manual operation is required. The winding support wheel helps maintain coil tightness during winding, while the added end support bracket is intended to improve cell-core winding precision. The mechanical arrangement keeps the operating sequence direct and accessible for repeated electrode-winding tasks.
Key Features
-
Adjustable Material Guide Channel: The guide-channel ruler plate can be adjusted vertically, horizontally, and front to back. This enables the guide position to be aligned with the electrode sheet width before winding begins.
-
Winding Support Wheel: A dedicated support wheel assists in maintaining winding tightness while the cell core is being formed. This feature supports controlled handling of the electrode and separator layers during the winding operation.
-
End Support Bracket: The added winding-tail support bracket is designed to improve cell-core winding precision. It provides additional support at the winding end during the formation of the electrode assembly.
-
Bidirectional Winding Motion: The winding mechanism can rotate in both forward and reverse directions. This gives the operator directional control during winding and during handling steps associated with the winding process.
-
Stepless Speed Adjustment: Winding speed is continuously adjustable from 0 to 170 revolutions per minute. Operators can select an appropriate rotation speed within the available range for the cell format and winding task.
-
Interchangeable Needle Configuration: Round and square winding needle assemblies can be changed to accommodate cylindrical and flat cell winding. Changing between flat-cell and cylindrical-cell operation requires changing the winding needle.
-
Foot-Valve Operation: The motor is actuated through the foot valve after the electrode leader is positioned and clamped. This operating method is integrated into the stated cell-winding procedure.
-
Compact Mechanical Layout: With an equipment size of L550 mm x 310 mm x 280 mm and a weight of 25 kg, the unit has a compact footprint. Its small overall size and straightforward operating arrangement support placement in laboratory electrode-processing areas.

Operating Procedure
| Stage | Procedure |
|---|---|
| Cell-core winding | Adjust the material-guide channel ruler plate so it matches the electrode sheet width. Place the electrode sheet into the guide channel, then position the leading end of the electrode sheet at the winding needle. Push the right needle inward so it engages with the left needle and clamps the electrode sheet. Press the foot valve to rotate the motor and complete winding. After winding, push the right needle away and remove the cell core. |
| Round needle replacement | Insert the left round needle into the bearing and tighten the coupling screw. Position the electrode sheet, then engage the right round needle with the left round needle to perform winding. |
| Square needle replacement | Insert the square winding-needle component into the bearing and tighten the coupling screw. Loosen and remove the support-wheel bracket from the two screws at the bottom to prevent interference. To adjust square-needle width, loosen the square-needle locking screw, set the required width, and retighten the screw. |
Configuration Considerations
The applicable flat-cell dimensions are defined by length, width, and maximum thickness. Before winding a flat cell, the guide-channel ruler plate should be adjusted to correspond with the electrode sheet width. The guide plate provides adjustment in up/down, left/right, and front/back directions, allowing the electrode sheet path to be positioned before the winding sequence starts.
For cylindrical cells, the applicable size is within Phi35 x L90 mm. The standard round winding needle is Phi3 mm. The round-needle procedure requires the left needle to be inserted into the bearing and secured by tightening the coupling screw. The right round needle is then engaged with the left round needle after the electrode sheet has been positioned.
For flat-cell winding, the square winding-needle assembly is installed in the bearing and secured at the coupling. The square-needle width can be adjusted by loosening its locking screw, setting the width, and tightening the screw again. The support-wheel bracket is removed from its two bottom screws during square-needle replacement to avoid interference with this configuration.
The winding mechanism provides adjustable speed from 0 to 170 revolutions per minute and can rotate forward or reverse. These controls are available alongside the guide-position adjustments and needle changes described above. The winding support wheel is used to maintain winding tightness, while the winding-tail support bracket is included to improve the precision of the wound cell core.
