MSK-110-A is a bench-top automatic single channel assembling machine for CR2032 or other series coin cells with 20mm Dia. The machine can automatically complete the coin cell assembly process by assembling in sequence, injecting electrolytes, and sealing cells. It uses a servo motor to drive the sealing process, ensuring stable and reliable pressure. MSK-110-AT is compatible with glove boxes or dry rooms.SPECIFICATIONS: Features Touchscreen control Automatic assembly: assemble in sequence, injection of electrolyte, and sealing of cells Suitable for use in glove boxes and dry rooms ( Double-sided glove box is recommended) Programmable amount of electrolytes and the number of injections Built-in vacuum pump Standard package is for assembling half coin cell, while full cell assembly can be completed by modified software Power Single Phase AC110V, or 220±10%V AC, 50/60 Hz, 200 W Assembling Sequence for Coin Cell For CR2032 coin cells, Positive Assembling Sequence: "cathode case, cathode disc, separator, anode disc, spacer, spring, and anode case". Assembly Time Approximately 40-65 seconds per cell (depends on the motor speed set) Loading Method Pre-load material manually, then assemble coin cell automatically Material Holding Tray ±0.1mm accuracy Assembling Accuracy Better than ±0.5mm Crimping Pressure Crimping pressure adjustable For the CR20 series coin cell, 500-700KG sealing pressure is recommended Consumables size: Postive Assembling Sequence for half cell) Positive 2032 case →Cathode Disc (15 mm)→ Separator (D19 mm, 1mm thick → Lithium Chip (16mm) → Spacer (15.8 x 1mm) → Belleville Washers →Negative 2032 case To get the desirable electrode and separator size, please consider the customized cutting die with MSK-T10. Pneumatic Pressure Input air pressure should be 60-80 psi. The connection tubing size is O.D. 8mm. An air compressor is highly recommended for pneumatic actions, but not included. pls order it from MTI or local stores) Note: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation.

Injection Pump Equipped with a peristaltic pump with adjustable Injection volume Electrolyte Injector One glass-made electrolyte injector is included Capacity: 100ml Max. Electrolyte injection times and position can be set in touch screen. Crimping Die CR2032 sealing die is included in the standard package; other sealing dies are available upon request 5000 sealing times Max. Operation Environment If any oxygen or humidity sensitive substances are used (eg: Li metal anode, solid or liquid electrolyte), a glovebox or dryroom is required. Single-chamber glovebox VGB-6-LD should be considered, but dual-chamber VGB-6-II-LD will leave more spaces for operation. Maintenance & Equipment Care Electrolytes are highly corrosive materials; therefore, the die set must be cleaned with ethanol after each experiment to avoid any corrosion damage. Please be aware that MTI is not liable for any losses/damages resulting from improper use, care, and maintenance, or abuse of the product. Application After coin cell assembly, the formation process is critical to forming the SEI layer and obtaining a stable OCV. Normally, at least 3-5 cycles are required. A flat rubber spring (CR20SPR-Rub) is beneficial to pressure distribution.
