Product Overview:
The Prismatic AL-Shell Battery Double Sealing Machine is an advanced automation solution tailored for the production of square aluminum-shell power lithium batteries utilized in electric vehicles (EVs). It seamlessly integrates a series of precise processes to ensure efficient and high-quality manufacturing, including vacuum-assisted variable liquid injection, precise weighing, quality control, and hermetic sealing.
Key Functionalities:
Automated Production Workflow:
The machine conducts a sequence of operations including barcode scanning linked with liquid injection, automated nail insertion, pre- and post-injection weight checks, defective product sorting, vacuum variable liquid filling under controlled atmospheres, high and low-pressure cycling for stabilization, residual fluid management, cup cleaning, and helium resealing – all while conveying batteries through the production line.
Enhanced Precision & Control:
Utilizes vacuum injection technology paired with a dual-stage pressure regulation system for optimal electrolyte filling, ensuring consistent filling levels and reducing the risk of battery deformation.
Robust Mechanical Design:
Employs heavy-duty rotary bearings to support the turntable, substituting traditional CAM mechanisms. This upgrade maintains turntable stability and precision cavity pressure during operation, enhancing product quality and longevity.
Innovative Clamping System:
Features an intelligent clamping mechanism on injection fixtures to secure batteries during processing, preventing deformation and ensuring accurate filling.
Ease of Maintenance & Operation:
Includes a wireless mobile HMI for real-time monitoring and simplified troubleshooting, promoting efficiency and reducing downtime.
Transparency & Monitoring:
Equipped with specialized glass injection cups, allowing clear visibility of the injection process for each station, facilitating immediate inspection and adjustments.
Enhanced Cleaning Mechanisms:
Pre-injection, a dedicated cleaning system for both cups and nozzles is integrated to enhance injection accuracy and prevent cross-contamination from residual substances.
Post-injection, a residual liquid collection system is appended to the nozzles to safeguard against electrolyte contamination of the battery shell.
Injection Nozzle Innovation:
Tapered inset injection nozzles are employed to eliminate potential injection nozzle steps, ensuring thorough cleaning at right-angle connections and preventing blockages or residue buildup.
This sophisticated machinery guarantees a streamlined, precise, and highly efficient manufacturing process for prismatic aluminum-shell EV batteries, contributing to enhanced performance and reliability in the rapidly evolving electric vehicle industry.
