Description

Technical Field

[0001] This utility model belongs to the field of inductor manufacturing technology, specifically relating to a lead wire cutting device. Background Technology

[0002] In the field of modern electrical equipment manufacturing, flat wire vertical winding technology is widely used in the production of high-precision windings, such as the windings for core components like drive motors in new energy vehicles, high-frequency transformers, and servo motors. As a key structure connecting the flat wire winding to the external circuit, the cutting quality of the wire leads directly determines the winding's installation accuracy, electrical connection reliability, and overall operational stability. With the industry's increasing demand for miniaturization, efficiency, and high reliability in electrical equipment, higher requirements are being placed on the cutting precision of flat wire leads. This requires not only strict control of length tolerances but also ensuring consistency in geometric parameters such as the perpendicularity of the lead end face and the flatness of the cut, to avoid potential hazards such as overheating and short circuits caused by poor contact.

[0003] In existing technologies, traditional flat wire lead cutting processes mainly rely on manual cutting tools or simple semi-automatic equipment. This approach has significant drawbacks: firstly, manual operation is limited by visual errors and variations in hand strength control, making it difficult to achieve stable control with millimeter-level precision. Actual lead length errors generally exceed ±0.5mm, far from meeting the winding consistency requirements of high-end equipment. Secondly, differences in operator skill levels and batch-to-batch equipment maintenance can lead to problems such as tilted cuts, burrs, and flattening deformation, severely affecting the quality stability of subsequent welding or crimping processes. Especially in large-scale production scenarios, the low efficiency and high defect rate of traditional processes have become bottlenecks restricting the capacity improvement of automated production lines.
