Dual-Head Roll-to-Roll Laser Drilling Equipment The Dual-Head Roll-to-Roll Laser Drilling Equipment is an advanced manufacturing system designed for high-precision, high-throughput laser drilling on flexible substrates in continuous roll-to-roll (R2R) production processes. This equipment integrates dual laser drilling heads with synchronized motion control, enabling rapid and precise micro-hole patterning on materials such as polymers, thin metals, and composite films. It is widely used in industries including electronics, energy storage, medical devices, and flexible circuits, where fine perforations or microvias are critical for functionality. Key Features 1. Dual-Laser Head Configuration The system incorporates two independently controlled laser heads, allowing simultaneous drilling operations on a moving web. This dual-head setup significantly improves throughput while maintaining high accuracy. Each head can be equipped with different laser sources (e.g., UV, IR, or ultrafast lasers) to accommodate diverse material requirements. 2. Roll-to-Roll Continuous Processing The equipment supports continuous feeding of flexible substrates from an unwinding module to a rewinding module, ensuring uninterrupted production. Precision tension control and web alignment systems maintain substrate stability during high-speed drilling, minimizing positional errors. 3. High-Speed Precision Drilling With advanced galvanometer scanners and high-repetition-rate lasers, the system achieves micron-level hole diameters (ranging from 10 µm to several hundred microns) at speeds exceeding thousands of holes per second. Real-time feedback systems adjust laser parameters dynamically to ensure consistent hole quality. 4. Automated Vision and Alignment Integrated vision systems with pattern recognition and auto-alignment capabilities compensate for substrate distortions or misalignments. This ensures accurate hole placement even on deformable or stretchable materials. 5. Flexible Process Control User-friendly software allows customizable drilling patterns, pitch adjustments, and multi-layer processing. Parameters such as laser power, pulse duration, and focal position can be optimized for different materials. 6. Multi-Material Compatibility The system is adaptable to various materials, including polyimide (PI), PET, copper foils, and battery separators. Optional gas assist modules reduce thermal damage and debris accumulation during drilling. Applications - Flexible Electronics: Creating microvias in flexible printed circuits (FPCs) and touch panels. - Energy Storage: Precision drilling of separator films for lithium-ion batteries to enhance ion flow. - Medical Devices: Producing breathable membranes or filtration components. - Packaging: Perforating films for controlled permeability. Advantages - High Productivity: Dual-head operation doubles output compared to single-head systems. - Superior Accuracy: Sub-micron positioning repeatability ensures uniform hole quality. - Scalability: Modular design supports integration with additional laser heads or in-line inspection systems. This equipment represents a cutting-edge solution for industrial-scale laser micro-drilling, combining speed, precision, and versatility for next-generation manufacturing needs.
