Automatic Filling Line for LiPF6 Electrolyte | Automated Cleaning and Filling

Product highlights of Automatic filling line for LiPF6 electrolyte:

• Dry air management system – dew point ≤ -50°C, continuous monitoring with automatic purge

• Robot-assisted handling – six-axis cobot for container alignment, nozzle insertion, and capping

• Filling repeatability ±0.1 g – gravimetric control with electromagnetic force restoration sensor

• Zero liquid spillage – nozzle features a spring-loaded seal and vacuum suck-back

• Anti-static design – all components grounded to prevent ignition of solvent vapors

• Batch traceability – 2D barcode reader integrates with MES

The core technology of automatic filling line for LiPF6 electrolyte:

The line employs a gravimetric fill-in-place method using a high-resolution load cell mounted under a tiltable container platform. A PLC commands a diaphragm metering pump with variable speed drive, executing a two-phase fill: bulk fill at 80% flow rate, then trim fill at reduced speed to approach target weight. After reaching setpoint, the nozzle retracts into a purge station where a solvent spray cleans its exterior. The collaborative robot then transfers the container to a capping station where a torque-controlled spindle applies a pre- sterilized PTFE liner cap. An inline capacitance sensor verifies proper seating. All cycle data, including fill weight, humidity, and operator ID, are uploaded to a local SQL database.
