AI Technical Summary

Technical Problem

Existing enameled wire cutting equipment is difficult to meet the high-precision cutting requirements of enameled wire with a diameter of less than 0.5mm, resulting in large cutting errors and affecting the yield rate of electronic instruments.

Method used

An enameled wire cutting device is designed including a frame, a winding wheel, a wire extrusion assembly, a tension assembly and a cutting assembly. Through the fit of the extrusion lug set and the design of the wire structure, the straight transmission of the wire in the X-axis direction is ensured, and the jump errors in the Z-axis and Y-axis directions are reduced. The driving wheel and tensioner are used to precisely control the length of the wire and keep the wire tension constant.

Benefits of technology

The cut of the enameled wire with a diameter of 0.1mm to 0.2mm is achieved with a precision of 0.05mm, which is suitable for finer enameled wire and scenes with higher accuracy requirements, and improves the cutting accuracy and efficiency.

Abstract

The utility model discloses an enameled wire cutting device which comprises a machine frame, a winding wheel arranged on the machine frame and used for winding a plurality of turns of wire rods, a wire extruding assembly arranged on the machine frame and used for conveying the wire rods in the X-axis direction, a tensioning assembly arranged on the machine frame and used for keeping the tension of the wire rods constant, and a cutting assembly arranged on the wire outlet side of the wire extruding assembly. The wire extruding assembly comprises at least two wire extruding wheel sets, each wire extruding wheel set comprises a fixed wheel fixedly arranged on the rack and a pressing wheel arranged on the fixed wheel, the wire is pressed between the fixed wheels and the pressing wheels and moves straightly in the X-axis direction, the wire passes through the multiple wire extruding wheel sets, jumping of the wire in the Z-axis direction is effectively reduced, the wire outlet error is reduced, and the wire outlet quality is improved. The wire outlet precision is improved; the driving wheel is arranged on the fixed wheel, the wire feeding length can be accurately controlled according to the wire outlet requirement, and the wire outlet precision is further improved.
