Solutions for PV module intelligent manufacturing

As a leading overall solution provider of intelligent manufacture in the global PV industry, LEAD always adheres to the concept of innovation, constantly upgrades and makes breakthroughs with the most advanced technologies, which promotes to move towards Industrial Era 4.0. LEAD provides PV module stringers, screen printing shingling stringers, Half-cell bussing machine and cell production line turnkey solutions, meanwhile, it has in-depth layout of TOPCon/XBC/HJT/perovskite and other PV intelligent manufacturing solutions, and keeps R&D for the next potential generation of PV Technology . Currently, LEAD has established strategic partnerships with Top-ranked PV companies.

LEAD provides customers with customized solutions, ensures quick responses to customers’ necessity, and help each customer achieve target production capacity in a short time. We provide different types of stringers: stringers integrated with laser cutting, XBC stringers, and 0BB stringers, compatiple with different processes such as TOPCon,XBC and HJT. At the same time, LEAD developed the industry’s first intelligent solution for GW-level TOPCon production with Eta≥26.5%, which makes a TOPCon smart factory with high efficiency. Combined with the self-developed MES system, production data can be inspected throughout the life cycle, which helps achieve an efficient management.

Whole Line Planning & Designing Capability

1. Lead has a professional and large group of process R&D team which makes it capable to takes all essential aspects into consideration at the very beginning, and professional in providing customers with turnkey solutions as well as a whole set of equipment for the production line with ensured efficiency and yield.

2. Complete turnkey production line configuration; processing equipment, automation equipment, logistics equipment, and inspection equipment are integrated and seamlessly connected.

3.Standardized design: Unified equipment standard and modular design, high interchangeability of parts of the production line reduces maintenance difficulty and reduce unnecessary spare parts categories. The appearance, interior, wiring, layout and lighting standards of all equipment are neat and consistent.

4. LEAD provides turnkey production line with high intelligence, including the pseudo-ID of wafers, rapid tracing of defective products, load information monitoring of robot cylinders, advance maintenance and preparation of spare parts, and it is also with high potential for upgrading.

1. Providing a production line with equipment from different suppiers. The yield rate and effeiency depends on the customers’ own technical level. Slow start-up and ramp-up which waste a lot of manpower and material resources from customers.

2. Only one processing section of the production line is self-made, leaving most of the equipment to be outsourced. Due to interest relationships, the customer needs to take the lead, making coordination and management difficult, and the docking response efficiency is low.

3. Because the designs and standards of different manufacturers are not unified, the mechanisms are not interchangeable; at the same time, the appearance, interior decoration, wiring, layout and lighting of the equipment are not uniform.

4. Informatization and intelligent upgrading of the production line is hard to realize due to poor compatibility and low integration between the industrial software of each manufacturer’s equipment.

Whole Line Efficiency

The capacity of each prodtion section is reasonably designed. The designed production capacity of a single line is 210 thousand pcs/day, and the stable throughput is 200 thousand pcs/day.

The designed production capacity of a single line is 185 thousand pcs/day, and the stable throughput is 180 thousand pcs/day.
