1. Four-station indexing turntable.
2. 1-out-1 cell fixture (illustration may show 1-out-2; for reference only).
3. Turntable support mechanism.
4. Fixture opening at the loading position; manual loading/unloading.
1. After cell is in position, the filling chamber lowers to press and seal against the baseplate.
2. Chamber evacuation; an aluminum-foil opening manipulator opens the gas bag to prepare for filling.
3. Filling needle descends into the gas bag and filling starts.
4. Vent to atmosphere; filling chamber rises; the fixture indexes to the next station.
5. Independent filling system injects the electrolyte.
6. The vacuum filling station is equipped with an electrolyte storage tank and degassing device to remove bubbles. The pump is above the storage tank; during long stops, pump & storage tank form a dedicated circulation loop.
7. The main inlet has a manual shut-off valve and can connect to the customer’s electrolyte supply line.
8. Filling-chamber vacuum: rated −80 to −85 kPa with real-time monitoring & alarm. Chamber sealing performance: ≤ −5 kPa / 60 s.
9. Time from atmosphere to rated vacuum ≤ 4 s; vacuum hold not required. (Plant must provide vacuum source ≥ 350 m³/h, vacuum −101 to −80 kPa.)
10. Max fill mass ≤ 1000 g. No cylinders inside the vacuum chamber; observation window provided.
1. Chamber lifting mechanism.
2. Gas-bag shaping mechanism.
1. After fixture is in position, the sealing chamber lowers to press and seal against the baseplate.
2. Completes evacuation → sealing → vent.
3. Sealing chamber rises; the fixture indexes forward.
4. Atmosphere to rated vacuum ≤ 4 s; vacuum hold 3 s. Sealing-chamber vacuum rated −85 kPa, with real-time monitoring & alarm.
5. Perform sealing after vacuum hold completes.
6. Independent sealing head for each cell; head material NAK80.
7. Max sealing-head working temperature 220 °C; max temperature difference across the head ±5 °C; real-time temperature monitoring & alarm.
8. Each sealing-head cylinder equipped with a digital pressure gauge; set a pressure window—alarm if out of range.
9. Stroke sensor on each sealing-head cylinder—alarm if not in position.
Power
l Three-phase five-wire AC380 V, 50 Hz, voltage fluctuation +10% / −10%; max start power 3 kW.
Compressed Air
l 0.6–0.8 MPa, pressure fluctuation ±1%; dry, oil-free, filtered, regulated.
l Consumption: 0.3 m³/h.
Machine Specifications
1. Weight: ≈ 1.5 t.
2. Overall size: L 2.0 m × W 1.85 m × H 2.2 m (incl. electrical cabinet; excludes service aisles).
3. Appearance: Aluminum parts natural anodized; all stainless external parts matte stainless. No metal-to-metal collision in moving parts. Cylinders may use copper; all other exposed/connector parts No-Copper. Paint smooth/glossy; color PANTONE – International Standard Warm Gray 1C.
Environment
1. Ambient temperature 25 °C ± 3 °C.
2. Relative humidity 10–30% RH; dry, well-ventilated; no acidic/alkaline corrosives.
3. Protective grounding required.
4. Floor load > 500 kg/m².
5. Within one week after contract signing, the Seller will provide foundation & layout drawings.
Machine composition: four-station fixture turntable; filling subsystem (storage + filling); vacuum degassing; vacuum sealing; frame & guarding; control system.
