This document outlines the operational constraints for the Atomfair-BP4090 punching machine. It is intended for use within a glovebox or confined space, with specific material thickness and dimensional limitations.
- Material Thickness Constraint: The machine is designed to punch materials with a thickness range of 0.005 to 0.5 mm, and exceeding this range may cause damage or poor cut quality.
- Glovebox Compatibility Constraint: The machine's compact design allows it to pass through a glovebox transition chamber with a diameter of 360 mm, but it must be verified that the chamber opening is clear and unobstructed before insertion.
- Punching Size Constraint: The punching size is customizable from 3 mm to 50 mm, and the specific die must be selected or fabricated to match the required electrode or separator dimensions.
This procedure describes the safe and effective operation of the Atomfair-BP4090 for punching battery electrode sheets or separators. It covers setup, operation, and post-punching steps within a glovebox environment.
Required Equipment: Atomfair-BP4090 Punching Machine, Custom punch die (Φ3mm~Φ50mm), Battery material sheet (0.005~0.5mm thickness)
- Prepare the machine
Place the machine on a stable surface inside the glovebox, ensuring the transition chamber is clear and the machine is oriented for easy access. - Install the custom die
Select and install the appropriate punch die (Φ3mm~Φ50mm) onto the machine, ensuring it is securely fastened and aligned with the lower die. - Position the material
Place the battery material sheet (0.005~0.5mm thickness) onto the lower die, aligning the area to be punched with the punch center. - Execute the punch
Firmly and smoothly press the actuation handle to drive the upper punch down, cutting through the material with a single, controlled stroke. - Retract and remove
Release the handle to retract the punch, then carefully remove the punched piece and any scrap material from the die area. - Inspect the cut
Visually inspect the punched piece for burrs, indentations, or incomplete cuts, ensuring the edges are clean and the dimensions are within tolerance. - Clean the work area
Use a soft brush or cloth to remove any material debris from the die and machine surfaces, maintaining a clean and safe work environment.
What is the maximum punching thickness and what materials can the Atomfair-BP4090 handle?
The Atomfair-BP4090 can punch battery materials with a thickness range of 0.005 to 0.5 mm, including positive/negative electrode sheets and separator paper. This range is specified in the product's technical parameters, ensuring compatibility with standard thin-film battery components.
Can the Atomfair-BP4090 be used inside a glove box, and what are the space constraints?
Yes, the Atomfair-BP4090 is designed for confined space operation, with an ultra-compact size that allows it to pass through a glove box transition chamber with a diameter of Φ360mm. Its overall dimensions are L207mm × W200mm × H330mm, and it weighs 12 kg, making it suitable for integration into inert-atmosphere glove box lines.
What customization options are available for the punching die size on the Atomfair-BP4090?
The punching size is customizable from Φ3mm to Φ50mm according to customer requirements, as stated in the technical parameters. This allows the machine to accommodate various electrode and separator geometries for different battery cell formats.
The Atomfair-BP4090 is a compact, corrosion-resistant punching press engineered for precision blanking of thin battery electrode sheets and separator materials (0.005–0.5 mm), with a customizable die range of Φ3–50 mm and a 25 mm stroke. Its high-precision slide-rail guidance and glove-box-compatible footprint (Φ360 mm pass-through) make it suitable for confined, inert-atmosphere processing environments.
Positive
- High-precision burr-free punching: The upper punch mold is guided by high-precision slide rails, ensuring punching precision without burrs or indentations on processed materials, which is critical for electrode integrity.
- Glove-box compatible compact design: Ultra-compact dimensions (L207×W200×H330 mm) allow free passage through a Φ360 mm glove-box transition chamber, enabling confined-space operation under inert atmospheres.
Trade-offs
- Thin-material thickness limitation: Punchable thickness is restricted to 0.005–0.5 mm, so the BP4090 is not suitable for thicker electrode stacks or current collectors outside this range.
- Custom die tooling required: Punching size is customizable (Φ3–50 mm) but requires custom molds per application, adding lead time and cost for each specific electrode geometry.
