Semi Automatic Cylindrical Battery Cell Grooving Machine

Product Overview

This semi-automatic grooving equipment is a specialized benchtop system engineered for precise outer-casing grooving on cylindrical battery cells and specialized capacitors. By automating the radial indenting process prior to electrolyte injection and crimping, this equipment creates a uniform, high-precision structural indentation that seats sealing O-rings and internal safety components with exact mechanical consistency.

Engineered primarily for battery research laboratories, prototyping facilities, and pilot-scale manufacturing lines, this system accommodates a versatile range of cylindrical steel housings including 18650, 21700, and 26650 formats, as well as aluminum capacitor housings up to 30 mm in outer diameter. Its intuitive programmable architecture ensures rapid transitions between different cell form factors while maintaining minimal setup time and maximum repeatability.

Built to withstand demanding laboratory and cleanroom chemical environments, this unit integrates an advanced PLC touchscreen interface with anti-corrosive physical controls. Rugged mechanical construction, combined with durable precision tooling rated for over one million cycles, delivers reliable, high-yield operation under rigorous continuous fabrication schedules.

Key Features

• Intelligent PLC Touchscreen Interface: The integrated touch-panel control system provides an intuitive interface for configuring and monitoring critical grooving parameters in real time, streamlining operational workflows and simplifying routine diagnostic maintenance.
• Electrolyte and Moisture-Resistant Hardware: Physical operational controls feature sealed metallic waterproof pushbuttons engineered to resist moisture ingress and prevent corrosive chemical degradation caused by accidental electrolyte contact.
• Digital Display Speed Regulation: An integrated digital speed governor allows operators to fine-tune rotational spindle speeds with high accuracy, ensuring optimal circumferential consistency across varying case materials and wall thicknesses.
• Adjustable High-Precision Grooving Tooling: The grooving mechanism enables micrometer-level depth adjustments between 1.2 mm and 2.0 mm with a tight machining tolerance of ±0.1 mm, delivering dimensional stability across extensive production batches.
• Ultra-Durable Tooling Blade Life: Fabricated from hardened wear-resistant tooling alloys, the high-precision grooving blades achieve an operational service life exceeding 1,000,000 processing cycles before requiring replacement or re-grinding.
• Multi-Format Cylindrical Compatibility: Designed with interchangeable tooling stations capable of handling standard commercial steel cylindrical housings—including 18650, 21700, and 26650—as well as custom aluminum capacitor shells with diameters up to Φ30 mm.
• Optimized Pilot-Scale Output: The semi-automated cycle provides efficient pneumatic feed-in and mechanical rotation, achieving sustained production throughputs of up to 400 units per hour without sacrificing dimensional precision.
• Compact Benchtop Footprint: Measuring only 740 mm by 250 mm by 350 mm, this self-contained system maximizes valuable cleanroom and laboratory bench space while maintaining rigid mechanical stability during high-speed rotation.
