Abstract

The invention belongs to the technical field of winding wire quality detection, and particularly relates to a winding wire insulating layer ring cutting device and a ring cutting system applying the same. The ring cutting device comprises a rack, a locking assembly and a ring cutting assembly are arranged on the rack, the locking assembly comprises two sets of clamping jaws, and the two sets of clamping jaws are coaxial so that a winding wire can penetrate in the axial direction of the clamping jaws and be clamped by the clamping jaws; the two sets of clamping jaws are rotationally assembled on the rack; the ring cutting assembly comprises a ring cutting knife, and a cutting edge of the ring cutting knife points to a section of winding wire between the two sets of clamping jaws; and the ring cutting assembly further comprises an elastic pressurizing part which is used for applying loading force towards the winding wire direction to the ring cutting knife so as to cut through an insulating layer. According to the ring cutting device, the working efficiency of ring cutting operation of the winding wire insulating layer can be improved, and meanwhile the quality of finished products obtained after ring cutting can also be effectively guaranteed. The ring cutting system further comprises a current detection device, so that the automation degree of the whole ring cutting process and the accuracy of later detection are further improved.

AI Technical Summary

Problems solved by technology

At present, the traditional ring cutting method is mainly manual cutting, that is, the operator holds a thin blade around the winding flat wire to cut the insulation layer, which is not only inefficient and time-consuming, but also has the following problems: First, the cutting direction Can not guarantee

When the thin blade circles the flat wire, it is often unable to form a perfect closed loop due to the vibration of the wire body or manual cutting errors.

Second, the cutting depth cannot be guaranteed, resulting in scratches on the surface of the conductor with different depths, which greatly affects the accuracy of later experimental data

Third, the thin blades are matched with thin flat wires, and it is easy to scratch your hands if you are not careful during operation, which poses a great safety hazard

Obviously, the above-mentioned manual circumcision method can no longer meet the high-quality and high-precision detection requirements of copper flat wires in the current high-speed development of industrial technology, and it needs to be solved urgently.
