[0002] Wire cutting and tinning are essential process steps in the manufacturing process of electronic products, especially airflow sensors. Traditionally, wire cutting and tinning are completed in two processes: manual wire cutting machine wire cutting and manual tinning. The two processes are inefficient, and in the process of manual tinning, it is difficult to ensure that the wire core penetrates the depth of the molten tin, resulting in problems such as inadequate tinning and tinning of the wire skin, which greatly causes material waste and manpower consumption, and greatly reduces the yield rate of products in the production and processing process.

[0003] Some existing production workshops use double-head automatic wire cutting and tinning equipment to realize automatic double-head tinning of cables, which greatly improves production efficiency and production yield and reduces labor costs. In order to ensure that the double-head tinning machine can effectively cut and strip the cables, the blades need to be polished and maintained regularly.
