FineJoin uses industrial RFID technology in the photovoltaic industry to support full-process traceability, ushering in a new era of intelligent photovoltaics.
Against the backdrop of accelerating global energy transition, the photovoltaic industry is booming. The industry chain includes multiple links such as silicon materials, silicon wafers, cells, module production and processing, and supporting projects. China has become a major producer of solar cells. However, the photovoltaic industry is complex and special, with large product export demand and extremely high requirements from users for quality and traceability, which traditional management methods find difficult to meet. For example, the error rate in crystal pulling and ingot batching is high, and the rework rate in production stages such as furnace loading, squaring, slicing, and inspection is high, making it difficult to track costs and losses. In addition, the production process is highly dependent on equipment, requiring strict equipment maintenance, repair, auxiliary material control, and data control.
To address these pain points, Shanghai FineJoin Smart Technology Co., Ltd. has launched a full-process traceability application solution for photovoltaics, covering multiple production stages such as crystal pulling plants, slicing plants, and battery plants, achieving intelligent data collection and transparent management throughout the entire process.
Crystal Pulling Plant: Intelligent Management of Hybrid Production Mode
In the crystal pulling plant, the production process of silicon ingots combines the characteristics of process industry and discrete industry. Starting from the machining of silicon ingot cutting, the silicon ingot and pallet are bound via RFID. All subsequent processes use RFID data collection to achieve production process tracking and management, linking quality inspection data to individual ingots. This approach effectively integrates data from different process stages and improves the refinement of production management.
Slicing Plant: Dual-Frequency RFID Technology Ensures Efficient Production
The slicing workshop uses UHF RFID and HF RFID technologies respectively to address the differences in process environments between the front-end and back-end processes. UHF RFID ensures the sensing distance and recognition speed during the transfer of crystal holders, while HF RFID meets the precise identification and multi-basket requirements of the back-end basket transfer. By installing readers on each machine and chips on carriers, intelligent data collection throughout the entire process is realized, enabling real-time understanding of process beat balance and bottleneck processes, dynamic analysis, continuous improvement, and increased yield rate.
Battery Plant: RFID and PLC Synergy for Precise Traceability
The production process of cells is complex, involving multiple processes and multiple transfers. FineJoin, with RFID technology at its core, combines data collection systems and PLC to collect information from each workstation and interact with the MES system. It provides various types of RFID readers to suit different installation scenarios while ensuring the reliability of industrial cables and communication gateways. In addition, through strict testing of basket chips and improved chip packaging design, the risk of chip damage is effectively reduced, ensuring the accuracy and continuity of data collection.
