A key device in photovoltaic module production, primarily used to apply reflective film strips onto the module glass to enhance sunlight utilization and improve the module’s photoelectric conversion efficiency.
1.Precise film layup: Equipped with a high-precision servo system, the film placement center deviation and straightness deviation are both controlled within ±0.2 mm, effectively preventing performance degradation caused by uneven film application. The peel strength after film strip attachment exceeds 1 N/cm, ensuring firm adhesion and preventing issues such as edge lifting or detachment.
2.Efficient production: Integrates core technologies including glass conveyance, precision positioning, film strip guiding, intelligent feeding, precise cutting, hot air heating, and pressure control. The single-cycle film layup tact time is ≤12 seconds, meeting high-speed production demands and significantly improving line efficiency. Overall product yield is ≥99.9%, and uptime is ≥99.5%, ensuring stable and reliable equipment operation under long-term, high-intensity use.
3.Compatibility with various specifications: Compatible with mainstream photovoltaic modules in the industry and supports multiple specifications of reflective film. It adapts to edge film layup processes, meeting the stringent requirements of high-efficiency cell module manufacturing such as PERC, TOPCon, HJT, and BC.
4.Secondary utilization of sunlight: By applying reflective film strips onto the glass, filling the cell gaps and string gaps in the module, and utilizing the microstructures on the substrate along with the total internal reflection principle at the glass-air interface, sunlight incident on the gap areas is secondarily utilized, improving overall sunlight utilization.
5.Intelligent inspection: Equipped with a film appearance inspection function that monitors the layup effect in real time, accurately identifying defects such as wrinkles, excessive length/shortness, missing strips, or misalignment. This prevents defective products from entering subsequent processes and enhances overall production efficiency.
6.Edge layup: Some equipment can be optionally equipped with an edge layup function, applying reflective film strips in the gaps between cells and the frame to further enhance sunlight utilization.
Reflective film layup at the gap between the edge of solar cells and the frame to further increase utilization of incoming sunlight to ≥ 99%.
