5 daysSemi-Automatic Electrolyte Filling Machine for Cylindrical Cells
1.1 This equipment is mainly used on a semi-automatic assembly line for cylindrical cells inside a glove box, for electrolyte filling and pressurized degassing (vacuum pressurization).
1.2 Process flow: Pre-fill manual weighing → Manual loading (place cells onto tray) → Electrolyte filling → Pressurized degassing → Manual removal of cylindrical cells → Post-fill manual weighing.

Description |
|
1 |
Tray |
1 |
1) Tray is fixed inside the equipment. 2) For changeover, only the cup set and tray need replacement. |
|
2 |
Filling |
1 |
1) After filling, no dripping from the filling needle is allowed. 2) Storage-tank pressure is automatically controlled; the system de-gasses the electrolyte and has low-level detection with automatic replenishment. 3) Main filling line includes bubble-purge function. 4) A stainless-steel filter ≥ 200 mesh is installed before the pump (in the filling tank). 5) Filling-needle height is settable. |
|
3 |
Degassing |
1 |
1) Degassing time can be set 10–30 min as needed. 2) Isobaric (equal-pressure) degassing: evacuate the degassing chamber and the cells; cycle count configurable per process. 3) Vacuum regulation range: up to −95 kPa. 4) Pressure control accuracy ±5%; positive/negative pressure drop ≤ 2 kPa/min. |
|
4 |
Electrolyte tank system |
1 |
1) Two tanks: one for motor-assisted degassing/settling, one for filling. 2) Tanks placed in a sealed dry environment. 3) Automatic electrolyte feeding. 4) Four dedicated drip trays for liquid collection. 5) After liquid discharge, residual electrolyte in pipelines and buffer tank ≤ 500 g. Each filling tank has two level-sensing points; software can select/switch the detection position to ensure residual < 500 g in tank. |
|
5 |
Glove box |
1 |
1) Cylinder-actuated transition-chamber door. 2) Transparent PETG viewing windows. 3) Transition chamber ≈ 400 × 400 × 400 mm. 4) Each section top requires one Ø110 inlet and one Ø110 outlet. 5) Each section top reserves a 100 × 100 mm square port for internal electrical installation; fastened by screws and sealed with sealant. 6) Six lamp holders in total. 7) Main frame: 40-mm SUS square-tube welded structure. 8) Box & base plate: 2 mm SUS304 welded; outer surface brushed finish. |

Control system |
1 |
Industrial PC + PLC as the control core for all machine motions. |
1. Structural materials prioritized as aluminum and stainless steel or plated anti-corrosion to ensure no rust/oxidation.
2. Quick tray removal for maintenance (remove one machine tray within 35 min).
3. Workbench shall have electrolyte drainage grooves and a collection tank; cable ducts on the workbench shall be aluminum.
4. After bubbles occur, electrolyte discharge is convenient, routed to the collection tank.
5. Electrical cabinet made of stainless steel, polished matte; stainless-steel screws and nuts.
6. Main machine frame uses square tube with baked-paint finish; other parts consider anti-corrosion and wear-resistance; ensure no rust/oxidation.
7. Neat routing for cables and pipelines; overall coordination; drag chains used for long-travel motion.
8. The machine is mounted under an upper rack; the filling area is sealed. The rack glass uses anti-corrosion PC transparent panels. The top is connected to the plant exhaust to quickly extract electrolyte/DMC odors and keep humidity inside/outside consistent.
9. HMI modules shall be clear and user-friendly for operators.
