This flexible graphite bipolar plate production line covers the complete process flow, including molding, impregnation treatment, and adhesive dispensing lamination. Centered around an automated system, the line achieves precise inter-process coordination and automated material transfer, effectively overcoming the efficiency bottlenecks and quality fluctuations associated with traditional segmented production. It ensures an end-to-end process—from graphite raw materials to sealed finished products—that is highly efficient, stable, and controllable.
PRODUCT DESCRIPTION
Flexible Graphite Plate Pressing Line: Specialized equipment primarily used for pressing expanded graphite plates into shape, performing visual inspections, cutting and stacking, and loading into baskets for fuel cell bipolar plate manufacturing. Expanded graphite plates are manually placed onto transfer carts and conveyed to the feeding station. A six-axis robot then uses suction to lift the plates to the pressing station. The pressed graphite plates become single-plate components. After visual inspection, defective items are rejected, while qualified products are loaded into baskets and transported via carts to the impregnation workshop.
Flexible Graphite Bipolar Plate Impregnation Production Line: Primarily used for impregnating bipolar plates, encompassing processes including impregnation, cleaning, rinsing, water bath curing, drying, and cutting.
Flexible Graphite Bipolar Plate Dispensing and Laminating Production Line: Includes basket unloading, cage loading, visual inspection, flatness inspection, adhesive dispensing and lamination, laser marking, barcode scanning, robotic workstation, pressure-holding station, central control, sealing A-side dispensing, sealing A-side curing, sealing B-side dispensing, sealing B-side curing, inspection/unloading and stacking, and airtightness testing.
This production line is specifically designed to meet the demand for large-scale, high-quality manufacturing of fuel cell core components. Its key advantages are as follows:
1. Precision and Quality Assurance
Utilizing a high-rigidity structure, precision transmission, and an optical alignment system, it achieves critical tolerances of flow channel machining within ≤±0.01mm and a surface roughness of Ra <0.8μm. This fundamentally ensures the gas tightness, electrical conductivity, and durability of the bipolar plates. Combined with machine vision-based in-line full inspection and constant temperature and humidity environmental control, the line guarantees product consistency and maintains a stable yield rate of over 99%.
2. Efficiency with Flexibility
Through production cycle optimization and multi-station parallel integration, it delivers high capacity with an annual output of XX million plates per line while significantly reducing work-in-process waiting time. The modular design supports quick changeovers, enabling flexible adaptation to the production of multiple models and sizes.
3. Intelligence and Reliability
The entire line is equipped with an MES (Manufacturing Execution System) for real-time production data monitoring, process optimization, and full-process traceability. Core components are sourced from top international brands, and the line features a centralized dust removal and powder recovery system. This ensures long-term stable operation of the equipment while achieving clean production and effective cost control.
