Battery Manufacturing EquipmentACEY-SP1200 prismatic module stacking and compression station
ACEY-SP1200 lines up finished prismatic cells and compresses them before the module is strapped. A servo motor and planetary reducer drive a screw module over a 1200 mm stroke, with a 500 KG maximum load setting. It handles cells 50–250 mm long and suits module assembly after cell production.

Where it sits: module assembly
ACEY describes a screw module driven by a servo motor through a planetary reducer, with a pressure controller and live stroke and force settings. The table gives a 1200 mm extrusion stroke and a cell range of 50–250 mm length, 20–100 mm width and 100–300 mm height. Tell ACEY how your cells will be oriented and ask which machine axis matches each cell dimension, and whether your full module fits within the compression travel.
The introduction mentions stacking, pressing and bundling. Automatic loading and the exact strapping tools are not described. Ask for an operating sequence from loose cells to a restrained module that marks every manual step, separator, end plate and strap. Cell sorting before the press and busbar welding after it are separate machines in ACEY's range.

Force units and safe cell loading
The page gives a maximum stacking load of 500 KG with a control error of 0.1 KG, while the introduction says more than 500 KG. Both use mass units for a force. Ask ACEY to state the force in newtons or another defined unit, together with the sensor range, calibration and the allowed working load.
Your cell maker's compression limits should set the fixture design. Check platen contact, end-plate stiffness, room for cell swelling and how load spreads across the cell faces. Ask ACEY to show its software limits, hardware limits and load threshold working, including recovery after a stop. Watch how the press reacts to a wrong force setting before it touches real cells.

Accept the compressed module, not just a press cycle
ACEY gives an example of 50 groups per hour with ten cells per group and a 'grafting rate' of at least 98%. Ask ACEY to define 'grafting rate', and treat both figures as examples until your own module has run. Time a trial covering cell loading, separators, pressing, strapping and removal. Set accepted module dimensions and decide whether to measure relaxation after the press releases.
ACEY lists 1 kW at AC 220 V/50 Hz, no compressed air, dimensions of 2370 × 500 × 1400 mm and a mass of 400 kg. Plan working space around that footprint for cell handling and strap installation. If several cell lengths or module layouts will share the press, ask for a format change demonstration and stored recipes. Positioning accuracy matters most where cells must line up for the later busbar step.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the complete module fit? | The page lists cells of 50–250 × 20–100 × 100–300 mm and a 1200 mm stroke. | Approve a module drawing showing orientation, end plates and strap access. |
| What load is safe and measurable? | The page gives a 500 KG maximum and also says more than 500 KG. | Get the force unit in writing and check it against your cell maker's limits. |
| What is the accepted production cycle? | The page gives 50 groups per hour of ten cells as an example. | Time loading through strap removal and measure the finished module. |
Equipment questions
Does 'stacking' mean building electrodes inside a cell?
No. SP1200 stacks cells that are already sealed in their cases into a module. Electrode stacking, separator placement, electrolyte filling and cell sealing happen earlier, on cell-making machines.

Still to confirm
- The force unit behind the 500 KG load and 0.1 KG control error, and the allowed working load for your cells.
- What 'grafting rate' means and how the 98% figure is measured.
- Which bundling tools and handling steps are automatic on the delivered station.
- Accepted module dimensions and cycle time on your own cells.
