High-Precision Rotary Pouch Cell Electrolyte Filling Machine
1. Equipment Name: Rotary (indexing) pouch cell electrolyte filling machine.
2. Model: LITH-ZPD0104F-6
3. Application Scope: Applicable to pouch cell sizes (refer to the commonly used cell specifications listed for this machine).
4. Filling Accuracy: ±0.1 g (single pump-head filling accuracy ±0.02 g).
5. Throughput: 11,000–13,000 cells / 10 h (reference model: cell spec table). Actual throughput depends on cell capacity and process; faster electrolyte imbibition yields higher throughput.
6. Operating Mode: Manual loading into fixtures → automatic filling → degassing/absorption → vacuum pre-sealing → manual unloading (load/unload share the same station).
7. Color Scheme: Frame blue; enclosure off-white/grey baked finish; other parts natural (SUS304, aluminum alloy, and other components).
8. Required Utilities / Power:
l Compressed air: 0.6–0.8 MPa (by buyer).
l Vacuum: −0.08 to −0.095 MPa (by buyer).
l Dry gas (N₂): working pressure 1–50 kPa (by buyer).
l Supply voltage: AC 220 V, 50 Hz.
l Power: 4.5 kW.
9. Overall Size & Weight:
l Main body: L 3800 × W 1600 × H 1900 mm (incl. front/rear pass-through chambers).
l Total weight: 1.2 t.
The system performs manual load/unload, automatic electrolyte filling, automatic vacuum degassing (absorption), and automatic vacuum pre-sealing. An indexing turntable advances fixtures through each station for continuous cyclic operation.
Operator places cells into the fixture and presses the foot pedal; the turntable indexes to the filling station. After filling, the fixture indexes to the vacuum degassing box (time, vacuum level, and number of cycles adjustable). Upon completion, the fixture indexes to the vacuum pre-sealing station. After pre-seal, the fixture returns to the start position where the operator removes the cell and loads the next cell to continue the cycle.

Pouch cell size (mm) |
Remarks |

1 |
|
Good consistency of the cells external dimensions. Dimensional compatibility requirements for rectangular pouch cells (mm): the fixture can hold 4–8 cells; overall dimensional tolerance ±2.0 mm. When A ≤ 60 mm, up to 8 cells per fixture; when A ≥ 60 mm, up to 4 cells per fixture. Dimension A: ≤ 130 mm (including tabs). Dimension B: ≥ 20 mm (excluding side-seal width). Dimension C: 20–140 mm (±2 mm). Dimension D: ≥ 30 mm (within 30 mm below the cell’s gas bag opening, the gas bag must have no stamped depressions/dimples). Dimension E: 2–20 mm. |
l Envelope & Pass-throughs: Outer size L 3.8 m × W 1.6 m × H 1.9 m; clear internal space L 1.6 m × W 1.6 m × H 1.2 m. Front pass-through 900 × 400 × 400 mm; rear pass-through 550 × 400 × 400 mm. Inner door: cylinder with foot-pedal control; outer door: manual.
l Conveyor in Front Pass-through: To ensure continuous feeding, a belt conveyor is installed and foot-pedal controlled.
l Primary Materials: SUS304 sheet and box-section; vacuum chambers in anodized aluminum; load-bearing frame in 50×50×3.0 mm steel box (painted); upper sheet-metal in 1.5 mm stainless, outer surface baked finish.
l Windows & Glove Ports: 6 mm imported clear PC window with stainless outer frame, screw-fastened; glove rings in corrosion-resistant material with sealing gasket to the PC panel.
l Long-reach Gloves, Leveling Feet & Casters: One pair of acid/alkali-resistant long-reach gloves (2 pcs). Four leveling feet and four casters; feet to be fixed after installation.
l Fabrication & Joins: Bottom plate fully welded for airtightness; joints use sealing strip + screws/nuts; quick-access service doors provided.

Process Function |
Functional Requirements |
|
1 |
Manual Load / Unload |
Operating method: (i) Place cell in fixture and press foot pedal to start. (ii) Right-side locating; fixture allows adjusting opening up/down to match thickness & height. (iii) Fixture is adjustable to accommodate multiple sizes. Inspection: (i) Operator checks appearance and dimensions; reject nonconforming cells. Incoming-material requirement: (ii) Cells must conform to the approved drawings; the equipment does not measure product dimensions. Overall dimensional tolerance within ±2.0 mm for a given model; exceeding this may affect stability and throughput. |
|
2 |
Gas-bag opening & Filling |
Operating method: (i) Index to gas-bag opening + filling station. (ii) Automatic gas-bag opening and filling. (iii) Filling dose & speed set on HMI; only when gas-bag opening = OK will filling occur—preventing electrolyte from dripping on the fixture or cell if no cell is present or the bag is not opened. Inspection: Alarm & inhibit if a cell is missing or not placed. |
|
3 |
Vacuum Degassing (Absorption) |
Operating method: (i) Index to vacuum degassing station. (ii) Chamber lowers to seal; vacuum + N₂ back-fill in cycles. Cycles and stepwise vacuum level are HMI-settable. Inspection: After parameters are set, the program auto-checks vacuum level, time, and cycle count. |
|
4 |
Vacuum Pre-Sealing |
Operating method: (i) Index to pre-seal station. (ii) System auto-verifies that the cell has been filled; if yes, performs vacuuming and heated pre-sealing automatically. Inspection: After parameters are set, the program auto-checks vacuum level, sealing time, and sealing temperature; if the sealing step is disabled, no sealing occurs. |
1. Electrolyte storage & supply: Two electrolyte tanks for automatic supply, storage, filling, and constant-pressure degassing, with switchover; low-level alarm when a tank is empty.
2. Anti-sticking (anti-seizure) system: When idle for long periods, the filling pump auto-indexes at set intervals; no dripping at the needle. Prevents crystallization and pump seizure.
3. Power-loss holding: In case of power failure, the degassing box remains pressed down (prevents a pressure spike from cylinder retraction). After power is restored, the system detects the prior step and resumes to completion.
4. Auto sealing logic: The sealing station only seals cells that have completed filling; unfilled cells are not sealed.
5. Gas-bag NG judgment: Before filling, system determines gas-bag opening OK/NG; the needle descends and fills only when OK.
6. Glovebox lighting: DC 24 V LED strip lights, corrosion-resistant, HMI-controlled.
