This pneumatic crimping machine must be supplied with dry inert gas (argon or nitrogen) when operated inside a glove box to avoid contamination. The sealing pressure must not exceed 1 MPa, and the exhaust must be vented externally to preserve the inert atmosphere.
- Gas Source Requirement: Use only dry argon or nitrogen for glove box operation; compressed air is not recommended due to moisture and oxygen content.
- Pressure Limit: Maximum sealing pressure is 1 MPa with recommended setting of 0.9 MPa to prevent mechanical damage.
- Exhaust Configuration: The exhaust port must be connected via a KF40 fitting to an external line to avoid contaminating the glove box atmosphere.
- Battery Jam Handling: The built-in screw-spring ejector in the upper die allows safe removal of jammed batteries without manual force.
- Short Circuit Protection: The machine incorporates built-in short circuit protection during crimping to prevent electrical hazards.
This procedure covers the safe setup and operation of the pneumatic crimping machine for button cell assembly. Follow these steps to ensure proper crimping and avoid damage to the cell or machine.
Required Equipment: Dry inert gas cylinder (argon or nitrogen) with regulator, KF40 exhaust fitting and tubing, Button cell components (case, electrode, electrolyte, etc.), Standard sealing mold (CR20 or as required)
- Connect gas supply
Connect the inert gas cylinder to the machine inlet using a suitable regulator and tubing. - Connect exhaust line
Attach a KF40 fitting to the exhaust port and route the tubing to an external vent. - Set sealing pressure
Adjust the manual regulating valve to 0.9 MPa using the pressure gauge. - Position the button cell
Place the assembled button cell into the lower die with the open side facing up. - Actuate crimp cycle
Activate the pneumatic system to lower the upper die and crimp the cell at the set pressure. - Retrieve crimped cell
Release the pressure and use the built-in ejector if the battery is stuck to remove it safely. - Inspect crimp quality
Verify the cell sealing height is within specification and check for any signs of deformation or leaks.
How does the sealing pressure accuracy of ±0.5% affect the consistency of coin cell crimping across different electrode materials?
The sealing pressure must be precisely controlled to ensure uniform crimp seals without damaging cell components. The manual regulating valve provides a maximum of 1 MPa with recommended 0.9 MPa and accuracy ±0.5%, which is critical for maintaining consistent seal height and preventing short circuits due to excessive pressure. The high-precision positioning ring on the lower die further controls sealing height to avoid damage.
Can the Atomfair-PBC721 accommodate both CR20 series cells and larger CR30 cells without changing the entire crimping assembly?
The standard sealing mold is for CR20 series, but optional molds are available for other sizes, including decrimping molds for CR16, CR20, CR24, and CR30 series. This means the machine can accommodate different cell sizes by swapping molds, though the sealing mold is specific to one size at a time. The compact dimensions (L220×W220×H420 mm) allow it to fit inside a Φ360 glove box antechamber, facilitating integration into inert atmosphere environments.
What are the specific gas supply and exhaust requirements for operating this pneumatic crimper inside a glove box?
The machine requires a gas source from an argon or nitrogen cylinder (or compressed air, but not recommended in a glove box). It consumes approximately 480 ml per crimping. The exhaust port is a special fitting connectable via KF40, which allows external exhaust to protect the glove box atmosphere from contamination. No electricity is needed, ensuring safe operation in inert environments.
The Atomfair Pneumatic Button Cell Crimping Machine combines precision sealing height control with a compact, pneumatically-driven design suitable for glove box integration, though it requires an inert gas supply for such environments and careful manual pressure calibration.
Positive
- Precise sealing height control: High-precision positioning ring on lower die controls sealing height to prevent damage from excessive pressure, enabling consistent crimping quality.
- Glove box compatible with inert gas: Dual gas supply allows use of argon or nitrogen, and external exhaust protects glove box atmosphere; compact size fits Φ360 antechamber for in-situ operation.
Trade-offs
- Inert gas mandatory for glove box: Compressed air is not recommended inside a glove box; argon or nitrogen must be supplied to maintain atmosphere integrity and avoid contamination.
- Manual pressure regulation required: Sealing pressure is set via a manual regulating valve with ±0.5% accuracy, demanding careful operator calibration to maintain the recommended 0.9MPa setting.
