This integrated cutting, flattening, and bonding equipment is specifically developed for the post-processing of flow battery flow channel plates (graphite/plastic composite plates, carbon‑plastic plates, etc.). It consolidates three traditionally separate steps—precision cutting, high‑temperature flattening, and automatic bonding—into a single automated production line.
It addresses common industry pain points of separate processes, such as low efficiency, poor positioning accuracy, and bubbles/wrinkles caused by manual bonding. This equipment is key to achieving large‑scale, standardized production of flow battery stacks.
PRODUCT DESCRIPTION
1. Precision Cutting Module
Function: High-speed, burr-free cutting of coiled or large sheet flow channel plate materials into preset flow field patterns and external dimensions.
Features:
●High‑precision rotary die cutting or laser cold cutting for smooth edges without clogging microchannels.
●Cutting accuracy ±0.05 mm ensures precise alignment of flow channels and sealing grooves.
●Supports automatic punching of continuous roll stock and separate waste collection.
2. Automatic Flattening Module
Function: Eliminates internal stress and warpage from cutting to ensure flatness meets stack sealing requirements.
Features:
●Multi‑stage heating (hot pressing + cold setting): heating section softens resin matrix to relieve stress, cold setting section locks shape rapidly.
●Temperature control ±2°C, programmable pressure for plates of varying thickness (0.5–3 mm).
●Post‑flattening flatness ≤0.2 mm/m².
3. Precision Bonding Module
Function: High‑accuracy lamination of cut flow channel plates with flow frames, sealing gaskets, or electrode materials.
Features:
●Vision‑guided alignment: CCD recognition of fiducial marks and frame position for automatic correction.
●Roll lamination / press lamination: servo‑driven constant‑pressure rollers or vacuum lamination ensures bubble‑free, shift‑free adhesion.
●Optional adhesive application: pre‑coated adhesive film hot bonding or precision dispensing + bonding.
1. Highly integrated, compact footprint: Three processes in one machine, saves ~40% floor space vs. traditional separate units.
2. High consistency: Eliminates secondary positioning errors from manual handling/transfer, yield ≥99%.
3. Improved productivity: Controlled cycle time typically 15–30 sec/piece (depending on material/process).
4. Data traceability: MES interface for real‑time data collection (pressure, temperature, position) enabling full traceability.
1. Flow battery stack assembly line: Final finishing unit before cell stacking.
2. Bipolar plate manufacturers: Sizing, flattening, and seal/edge bonding of finished bipolar plates.
3. Energy storage system integrators: In‑house stack production for independent control of key component processing.
