All-Vanadium Redox Flow Battery Stack Assembly Line

Main Components

This assembly line consists of fully functional physical modules and an intelligent software management system, ensuring full-process control from material handling to finished product output.

1. Material Pre-treatment System

●Component Processing Unit: Performs automatic cleaning, plasma treatment, or preheating on key components such as end plates, insulating plates, current collector plates, bipolar plates, separators, and gaskets.

●Bipolar Plate Processing Module: Integrated with bipolar plate hot-melting or welding equipment, and equipped with online inspection functions to ensure plates are defect-free.

●Automatic Feeding System: Automatically transports various materials to designated stations according to the production takt time.

2. Core Assembly Equipment

(1) Automatic Dispensing and Film Lamination Unit:

●Automatic Dispensing: Applies high-precision, quantitative adhesive to gasket grooves or designated areas.

●Automatic Film Lamination: Achieves automatic positioning and lamination of the separator onto the electrode frame, preventing contamination or wrinkling caused by manual contact.

(2) Automatic Stacking System: Utilizes high-precision robots or gantries to pick and place layers sequentially according to a preset stacking sequence (e.g., bipolar plate, separator, gasket).

(3) Stack Assembly System and Servo Hydraulic Press: Provides high-precision press-fit force control and displacement monitoring, ensuring tight contact between stack components and uniform compression.

(4) Auxiliary Mechanisms:

●Stack Turning Mechanism: Enables 180-degree turning of the stack during assembly, facilitating bipolar stacking or double-sided assembly.

●Rotary Conveyor and Lifting Devices: Enable flexible material flow within the line, connecting different stations and optimizing plant floor space layout.

3. Intelligent Control and Inspection System

●Stacking Recipe Management System: A core software platform that stores and recalls stacking recipes for different stack types (e.g., layer count, pressure, temperature, adhesive path), enabling rapid changeovers.

●CCD Vision Inspection System: Performs online inspections at critical stations (e.g., after dispensing, during stacking), automatically judging adhesive path integrity, component positioning accuracy, and foreign matter intrusion.

●Air Tightness Test Station: Simulates battery operating conditions to perform leak detection on semi-finished or finished stacks during the assembly process.

Main Functional Features

1. Full-Process Automation
The line possesses the capability for automatic dispensing, automatic film lamination, automatic stacking, and automatic inspection of individual components. From feeding to press-fitting, manual intervention is minimized throughout the process, ensuring the consistency and cleanliness of stack assembly.

2. High-Precision Vision Guidance and Inspection
Integrated with advanced CCD vision systems, used not only to guide robots for precise picking and placement of delicate separators and bipolar plates but also for real-time inspection of:

●Adhesive line width, thickness, and continuity (judgment conditions can be freely set).

●Edge alignment of various components.

●Surface defect identification.

3. Intelligent Press-Fitting and Data Traceability

●Servo Press Control: Achieves closed-loop control of pressure and displacement via a servo hydraulic press, ensuring uniform force distribution on the stack.

●Data Traceability System: Features test result collection, statistical analysis, and traceability functions. Each finished stack has a unique "ID" linked to all its process data during assembly (e.g., pressure curve, torque values, air tightness results), facilitating quality management and future maintenance.
