Description

1

Enclosure / guarding

1

l 40×40 square-tube + Q235 welded frame; clean exterior lines; local stiffeners for stability.

l Ergonomic layout with adequate operation/maintenance space; transparent acrylic viewing windows; internal cabling in cable ducts.

l All fixed pipelines are corrosion-resistant; fittings in electrolyte-risk areas are stainless steel.

l Infeed buffer length 1316.5 mm; outfeed buffer length 575 mm.

2

Rotary-table fixtures

4

l Operator places cells into rotary fixtures (1-out-1).

l Indexer-driven table; surface covered with SUS304 for corrosion resistance and easy cleaning.

l Quick changeover with graduated scales on adjustments.

l Fixtures use AL6061 + SUS304 (corrosion-resistant, easy to clean).

3

Atmospheric filling mechanism

1

l Atmospheric filling to cells; gas-bag actuation by vacuum with independent vacuum circuits for chamber and suction cup. No fill when fixture is empty. Fill timeout protection—stops pump immediately if no “fill complete” signal to PLC to avoid contamination.

l Gas-bag opening by stepper motor, stroke set on HMI.

l Waste-liquid box provided.

l EPDM suction cup.

l One needle ↔ one pump; fill mass set on HMI; changeover fill mass set on HMI as well.

4

Vacuum degassing mechanism

1

l Performs vacuum degassing after filling (time adjustable).

l Vacuum ≤ −90 kPa;

l Hold time & cycle count adjustable;

l Vacuum manifold (distributor) included.

5

Vacuum sealing mechanism

1

l Performs vacuum sealing (time adjustable), vacuum to −95 kPa.

l Chamber with quick clamps & guide bearings for rapid removal/maintenance.

l Vacuum manifold included.

l Sealing temperature RT–250 °C adjustable, 1 set of sealing heads.

6

Electrolyte tank system

1

l Two tanks: storage & filling; auto refilling.

l Storage tank supports stirring and vacuuming to mitigate bubbles and prevent underfill/dripping.

l One-key return of electrolyte during product change to reduce operator errors and speed changeover.

l Tank material: SUS304L;

l Seals: EPDM.

l Each storage tank ≥ 5 L with level sensors; if level does not change during feeding, alarm.

7

Control system

1

l PLC-based motion control.

l Alarms for temperature, air pressure, reset; machine runs only when set temperature & pressure are reached.

l Sealing-head temperature set via temperature controller with PV/SV display.

l Auto / Semi-auto / Manual modes with interlocked memory and reliable interlocks between dependent actions. Anti-mis-step foot switch prevents misoperation.
