Product Description

Product Description

 

Functionality Overview:

This advanced machinery is specifically designed for the automatic, conventional, or vacuum-based electrolyte injection in prismatic aluminum shell batteries. Its comprehensive operations encompass:

• Conveyor belt feeding with pre-filling barcode scanning.
• Short-circuit and Hi-pot (high potential) testing for quality assurance.
• Pre-filling weighing and defective product sorting.
• Automated fixture-based electrolyte injection, followed by sealing check.
• Sequential processing, including high and low voltage soaking, to enhance battery performance.
• Collection of residual liquid post-injection.
• Injection cup and nozzle cleaning mechanisms to maintain precision and hygiene.
• Post-injection weighing and conveying, with additional nozzle cleaning using DMC solvent.
• Application of liquid glue and plastic nail inspection.
• Final discharge of processed batteries onto the conveyor.

Our Advantages

Technical Innovations:

• Zero Pressure Difference Injection: Eliminates pressure discrepancies between battery interior and exterior during injection, safeguarding the battery shell from deformation.
• Efficiency Boost: Reduces soaking time, enhancing overall equipment productivity.
• Nitrogen Positive Pressure: Maintains 0.6MPa during injection to manage internal and external pressures optimally.
• Cleaning & Contamination Control: Incorporates pre-injection cup/nozzle cleaning and post-injection residual liquid collection systems to minimize cross-contamination risks.
• Precision Nozzle Design: Utilizes tapered nozzles to navigate battery inlet angles effectively, ensuring thorough cleaning.
• Scalable Production: Allows for the addition of injection units to match production demands without being bound by static process times.
