Photovoltaic cell sintering furnace mesh belt

The photovoltaic cell sintering furnace mesh belt is a type of heat-resistant conveying component specifically used for the continuous transport of solar cells during high-temperature sintering, curing, and metallization processes. Its design focuses on ensuring uniform heating of the cells in high-temperature zones, maintaining stable positioning, and achieving an accurate conveying path. This mesh belt is primarily made from flexible metal wires suitable for high-temperature and corrosive atmospheres, with commonly used materials including AISI 314 and Cr20Ni80. These heat-resistant alloys maintain strong mechanical performance and oxidation resistance under continuous heating and thermal cycling, reducing risks such as metal fatigue, elongation, or surface oxidation. As a result, the mesh belt can retain reliable conveying performance even during long-term operation.To meet the high precision requirements of photovoltaic cell positioning, the mesh belt adopts a balanced weave structure combined with a crimped cross-rod embossing process, ensuring tighter coordination between spiral rods and cross wires. This design minimizes lateral deviation caused by thermal expansion and enhances overall flatness. The welded positioning pins on the belt surface are another key feature of this structure. These pins undergo titanium-coating treatment to enhance wear resistance and corrosion resistance. During production, the pins are arranged according to cell dimensions and furnace transport pitch, and are accurately welded to the mesh belt using TIG welding. This ensures that each solar cell remains stably positioned throughout the sintering process, preventing tilting, slipping, or uneven heating.
