Description

Technical Field

[0001] This utility model belongs to the technical field of welding strip processing equipment, and more specifically, relates to a welding strip cutting mechanism. Background Technology

[0002] In the photovoltaic industry, ribbon cutting is a crucial step in module manufacturing. The ribbon is used to connect solar cells to conduct current and generate electricity. During production, because the ribbon needs to be soldered onto the cells, its surface is usually coated with flux and other substances. However, this flux may adhere to the cutting blade during the cutting process, accelerating blade wear and affecting cutting accuracy, thus increasing production costs and reducing the quality of the ribbon cutting.

[0003] Existing solder strip cutting equipment typically cuts the solder strip directly without effectively isolating the influence of flux and other substances on the cutting blade. Flux residue easily forms deposits on the cutting blade surface, increasing friction during the cutting process and shortening blade life. Furthermore, existing cutting equipment lacks an effective flow guiding device, failing to effectively remove flux and impurities, thus affecting the continuity and efficiency of cutting and the blade's lifespan. Therefore, a solder strip cutting mechanism with a flow guiding function is needed to reduce the impact of flux on the cutting blade, extend its lifespan, and improve the cutting quality of the solder strip.
