Equipment Name |
Applicable Product |
Remarks |
|
Rotary automatic electrolyte filling machine |
Prismatic cells |
1-out-6 differential-pressure filling; pre-/post-filling scanning & weighing, MES data interface |
2.1 This equipment adopts differential-pressure filling for prismatic cells.
2.2 Process steps: manual barcode/QR scanning and weighing, manual place/remove cells to/from fixtures, automatic filling, differential-pressure hold (vacuum/pressurization), manual wipe residual electrolyte at the fill port and insert the sealing plug.
2.3 Installed inside a dry room. The operator side is open and protected by a safety light curtain; the other three sides use movable doors/windows.
2.4 Scan/weight data are stored in an industrial PC; the database is separate from the PLC. Post-scan/weight data are documented and viewable on the IPC monitor. The machine provides TCP/IP or RS-232 interfaces for data communication/networking and future expansion (ports reserved). Data can be exported via USB or uploaded to the MES.

I. Upper/Lower Enclosure
1. Upper/lower frames: square-tube, baked paint; door/window sheet-metal painted; view windows use PC transparent panels.
2. Infeed/outfeed isolate the interior from the exterior.
3. For use in a dry room; door/window sealing is not applied.
4. Foot-switch start at the console; light curtain at loading position.
5. Equipped with one vacuum tank and one pressure tank.
II. Rotary Fixture Mechanism
1. Two-station rotary table driven by motor + indexer; while one station is in filling/holding, the other allows manual load/unload without interference.
2. Fixture cavity is common; baffles are model-specific and must be replaced when changing cell models.
3. Operator loads/unloads cells into the fixture baffle.
III. Scanning & Weighing
1. One scanner and one electronic balance, shared pre/post filling.
2. Scan/weight data are bound to the IPC for automatic recording and analysis.
3. NG in scan/weight triggers software alarm; manual sorting.
IV. Electrolyte Supply System
1. Two electrolyte tanks: one for degassing/standing, one for filling; ≥ 5 L each.
2. Automatic refilling and automatic degassing functions.
V. Positive-Pressure System
3. External compressed air and nitrogen supplied by buyer.
4. Machine pressure tank stabilizes positive pressure.
5. 1-out-6 manifold, series-controlled lines.
VI. Vacuum System
1. External vacuum source supplied by buyer.
2. Machine vacuum tank stabilizes negative pressure.
3. 1-out-6 manifold, series-controlled lines.
VII. Filling Mechanism
1. Fill volume set on touchscreen; pump is a metering pump.
2. Six filling channels; up to 6 cells can be filled simultaneously.
3. Independent setpoints for vacuum and positive pressure; if actual values fall below/above setpoints, system automatically alternates vacuum/pressurize cycles.
4. Metering cups store electrolyte; nozzle seals to the cell fill port.
5. Differential-pressure filling with vacuum + positive-pressure operation.
6. Equipped with one intelligent piston pump that doses to six metering cups in sequence.
7. Vacuuming, pressurizing, venting, and liquid transfer are controlled by dedicated valves.
8. All wetted parts are corrosion-resistant materials.
9. Nozzle downforce adjustable; process requires ≥ 10 kgf per cell.
VIII. PLC Control System
1. PLC program controls the machine; parameters are set via touchscreen.
2. Functions include statistics & display of all alarms/faults, I/O and process states, other control/process/diagnostic information, real-time process data, throughput & FPY statistics, material info, and run/stop time.
