Introduction

Energy storage is an essential component in the development of the new energy industry. A complete energy storage system typically comprises energy receiving devices, storage devices, and energy output devices. Central to this system is the energy storage cabinet, which houses critical components such as control systems, batteries, inverters, and sheet metal structures. The quality and cost of the sheet metal structure and casing significantly affect the performance and application of energy storage products.

In recent years, the energy storage industry has experienced explosive growth. As the core carrier of the energy storage system, the manufacturing efficiency and quality of the cabinet are paramount. Han’s Laser has developed the MLU series automated sheet metal forming solution to meet the growing demands of energy storage cabinets. Designed for fabricating key components like cabinet bases, side panels, doors, and box frames, the MLU series integrates an intelligent material warehouse, laser cutting, bending, and laser welding, creating a seamless production process. This solution enables manufacturers to overcome capacity bottlenecks, rapidly respond to high-volume orders, and gain a competitive edge in the new energy sector.

Smart Storage: The First Step Toward Intelligent Manufacturing

The MLU series production line can be equipped with a range of intelligent storage options, including raw material carts and multi-column vertical smart material warehouses, with customizable shelf configurations. These compact, multi-layer storage systems occupy only a fraction of the space required by traditional warehouses—just one-fifth of the area. Equipped with functions such as weighing, height limitation, sheet separation, and thickness measurement, the intelligent warehouse ensures a safe and efficient start to the automation process.

From raw material storage to finished product interim storage, the warehouse can handle daily throughput of over 100 tons, continuously supplying high-quality raw materials to the laser cutting process. This achieves “darkroom storage,” where materials are handled without manual intervention, ensuring smooth and automated operation.

Precision Cutting: Elevating Smart Manufacturing Efficiency

Once raw materials are automatically fed from the smart warehouse, a robotic arm integrates the material loading and unloading process, swiftly placing the material into the laser cutting machine. The Han’s Laser cutting machine, known for its classic gantry structure, offers exceptional stability and durability. With outstanding performance in cutting precision, efficiency, yield, and sheet metal utilization, it ensures smooth, clean-cut edges that require no secondary processing. This enables a seamless transition to the bending process, exemplifying the true “cut-to-bend” connection.

Vision Sorting: Precision and Efficiency Combined

After laser cutting, the visual sorting robotic arm takes over. Equipped with industrial-grade high-resolution cameras and deep learning algorithms, the arm accurately identifies the contours and positions of each workpiece in real-time, enabling efficient sorting. The system can automatically classify and stack parts according to size or order requirements, ensuring high sorting accuracy and flexibility to adapt to a variety of production scenarios.

Bending Unit: Balancing Precision and Speed

For complex bending tasks, such as those required for energy storage cabinet door panels and supports, Han’s Laser bending machine integrates advanced technologies. With repeat positioning accuracy of ±0.01mm, it ensures consistent bending angles and precision across all cabinet components.

The bending unit combines a CNC press brake with a robotic arm that features visual capabilities. This allows for real-time scanning of workpieces, quickly recognizing their contours and dimensions. The robotic arm adapts its grabbing strategy and selects the appropriate bending program, ensuring accurate material alignment and bending. This solution supports 24/7 continuous production, enabling the fast-switching of small batches and multiple product types, reducing manual labor, improving productivity, and significantly cutting costs.

Laser Welding: Creating High-Reliability Structures

In the cabinet frame assembly stage, laser welding equipment excels. Integrating Han’s self-developed laser sources, oscillating laser welding heads, and control systems, these machines provide high-quality, stable welding over long durations. The resulting welds are smooth and aesthetically pleasing, with minimal thermal distortion, often requiring no further processing. This drastically reduces post-production time, enhances efficiency, and contributes to a more streamlined manufacturing process.

Conclusion

Han’s Laser MLU series automated sheet metal forming solution integrates laser cutting machines, bending machines, laser welding machines, and production line scheduling control systems, all deeply fused through Han’s proprietary technologies. This system enables automated production scheduling, reducing the need for human supervision, saving labor and space costs, and significantly enhancing automation levels and production efficiency in workshops. By upgrading the manufacturing process for energy storage cabinets, Han’s Laser sets a new standard for intelligent production in the industry, providing a key driver for the advancement of smart manufacturing in the new energy sector.
