The large-tonnage servo press for flow battery stack assembly is key equipment specifically developed to overcome the core bottlenecks in the large-scale manufacturing of flow batteries.
It features a heavy-duty closed-frame construction and all-digital servo drives, capable of precisely delivering hundreds of tons of stable, controllable pressure. This ensures uniform compression at the microscopic interface and precise overall thickness control at the millimeter level across the super-large stacking surface, encompassing hundreds of bipolar plates, electrodes, and seals within the stack.
PRODUCT DESCRIPTION
Core Advantages and Functional Features
1. High-Precision Servo Control
●Closed-Loop Control: Built-in high-precision pressure sensors and grating scales/magnetic scales provide real-time feedback on pressure and displacement data.
●Full Closed-Loop Pressing: Supports "Pressure Control," "Position Control," and "Segmented Pressure/Position Control" modes. For example, position control can be used for rapid approach in the initial pressing stage, switching to pressure control for slow compression upon contacting the workpiece to prevent damage to fragile electrode materials.
●Multi-Point Pressure Holding Uniformity: For large-format stacks, the servo pump and precision hydraulic circuit design ensure uniform pressure distribution across the entire worktable surface, preventing "sagging" or localized over-pressing after stack assembly.
2. Large Tonnage and High-Rigidity Structure
●Frame Structure: Utilizes an integral steel plate welded construction or a pre-stressed wire winding structure (for ultra-large tonnages), optimized through finite element analysis, offering extremely high rigidity and eccentric load resistance to ensure minimal deformation under heavy loads.
●Guide System: Equipped with extended high-precision column guides or 8-way rail guides to ensure the perpendicularity and repeatability of the slide motion.
3. Intelligent Process and Data Traceability
●Recipe Management: The PLC control system stores pressing process parameters for multiple stack types, supporting one-click changeover without manual readjustment.
●Data Recording: Records displacement-pressure curves in real-time during the pressing process and uploads data to the MES system. Supports pressure monitoring at critical points (e.g., pressure value when the seal compression reaches a specified position), enabling full lifecycle traceability with "one stack, one file."
●Self-Diagnostics: The system monitors oil temperature, oil level, filter blockage, and motor overload in real-time, displaying alarm information in Chinese.
4. Energy Efficiency and Environmental Friendliness
●Servo Hydraulic System: Compared to traditional fixed-displacement pump presses, the servo system adjusts motor speed and flow based on actual demand. During standby and pressure-holding phases, the motor barely rotates, achieving comprehensive energy savings of 30%-70%.
●Low Noise: Reduces the use of relief valves, maintains low oil temperature, and typically keeps operating noise below 75 decibels.
●Cleanliness: Employs high-standard sealing to meet the cleanliness requirements of battery manufacturing workshops (e.g., Class 100,000 or Class 10,000 cleanroom standards).
5. Safety Protection
●Safety Light Curtain: The work area is equipped with a light curtain protection system, immediately stopping the machine if an operator's limb enters the hazardous area.
●Dual-Button Start: Requires simultaneous two-hand operation to prevent accidental activation.
●Hydraulic Safety Lock: The upper die is fitted with a hydraulic self-locking device to prevent slide descent during power outages or hose failures.
Optional Configurations
●Automatic Feeding/Unloading System: Equipped with heavy-duty roller conveyors or AGV interfaces for automated stack transfer.
●Centering Positioning Mechanism: Multi-directional hydraulic or pneumatic manipulators assist in precise alignment of stack components before pressing.
●In-Line Inspection: Integrated thickness measurement and insulation resistance testers measure stack height and insulation performance immediately after pressing.
●Temperature Control System: Optional heating platens and temperature control systems for stacks requiring thermal curing processes.
