Description

Technical Field

[0001] The invention belongs to the technical field of welding strip processing equipment, and more specifically, relates to a welding strip cutting mechanism. Background Art

[0002] In the photovoltaic field, the cutting of welding ribbons is an important part of component manufacturing. Welding ribbons are used to connect solar cells to conduct current and achieve electrical energy output. During the production process, since the welding ribbons need to be welded to the cells, their surfaces are usually coated with substances such as flux. However, these fluxes may adhere to the cutter during the cutting process, accelerating the wear of the cutter and affecting the cutting accuracy, thereby increasing production costs and reducing the quality of welding ribbon cutting. Existing solder strip cutting equipment usually cuts the solder strip directly, but fails to effectively isolate the influence of substances such as flux on the cutter. Due to the residual flux, the cutter surface is prone to scale, which increases the friction during the cutting process and shortens the life of the cutter. In addition, the existing cutting equipment lacks an effective diversion device and cannot effectively discharge the flux and impurities, thus affecting the continuity and efficiency of cutting and the life of the cutter. In view of the above problems, a solder strip cutting mechanism with a diversion function is needed to reduce the influence of flux on the cutter, extend the service life of the cutter, and improve the cutting quality of the solder strip.
