Automatic Layout & Bussing Integrated Machine ALU-HBL
The Ooitech ALU-HBL Automatic Layout & Bussing Integrated Machine is an advanced all-in-one solution that combines cell string positioning, precision layout, and electromagnetic busbar welding into a single compact unit. Designed for modern half-cut and MBB solar module production lines, this machine receives strings directly from the tabber stringer and completes alignment, layout, and busbar soldering on the glass surface with exceptional accuracy and speed.
By integrating layout and bussing processes into one machine, the ALU-HBL significantly reduces the transfer distance between production steps, minimizes the risk of micro-cracks, and delivers a cycle time of approximately 40 seconds per glass panel. It supports a wide range of cell sizes from 156mm to 230mm and busbar configurations from 5BB to 28BB, making it fully compatible with PERC, TOPCon, HJT, and other mainstream cell technologies.
Whether you are building a new solar panel production line or upgrading an existing facility, the ALU-HBL offers the precision, throughput, and reliability required for high-quality module manufacturing from 5MW to 1GW capacity.

Technical Advantages
Integrated Design and High Throughput
The ALU-HBL combines the layout and bussing processes into a single machine, eliminating the need for separate equipment and reducing handling distance between steps. This integrated approach lowers the risk of micro-cracks during transfer and improves overall cycle time by approximately 20% compared to conventional separated systems.
Compact and Space-Saving Structure
The symmetrical layout design reduces the machine footprint by approximately 17% compared to traditional standalone units. The compact structure also supports mirror line installation, providing maximum flexibility for factory floor planning.
High-Precision Alignment System
An independent XYU correction platform driven by linear motors delivers positioning accuracy of ±0.1 mm. This ensures that every cell string and busbar is placed with exact precision, resulting in consistent module quality and reliable electrical connections.
Reliability and String Protection
The machine features a reduced contact area design for handling cell strings, which significantly lowers the breakage rate to ≤0.2‰. Integrated CCD inspection technology monitors string position in real time and detects missing ribbon faults instantly, preventing defective modules from advancing through the production line.
Smart Detection and Error Correction
Built-in point-solder and virtual-weld detection units automatically identify welding defects and trigger error correction without the need for secondary alignment. This intelligent feedback loop maintains production quality while maximizing throughput.
Advanced Busbar Preparation Unit
The dual pulling mechanism enables continuous busbar feeding and cutting for uninterrupted production. Optional features include laser black-paint removal and automatic punching, allowing the machine to handle various busbar specifications and preparation requirements in-line.
Wide Compatibility
The ALU-HBL supports cell sizes from 156mm to 230mm and busbar counts from 5BB to 28BB, making it suitable for manufacturing a broad range of solar modules including half-cut, MBB, PERC, TOPCon, and other advanced cell technologies.
