Automatic device and method for bundling metal filaments

Abstract

The invention relates to an automatic device for bundling metal filaments. The device is characterized by comprising a hopper assembly with a variable state, an excitation assembly, a wire guide witha wire guide hole inside, a mechanical clamping jaw capable of being opened and closed, and an alignment guider with a guide hole inside. Another technical solution of the invention is to provide an automatic method for bundling the metal filaments, and the method is characterized in that the device is adopted. Due to the adoption of the technical scheme, compared with the prior art, the device and the method have the following advantages and positive effects that the difficulties of low manual operation efficiency and high labor intensity are solved; by replacing different wire guides, beam brushes with various specifications can be manufactured; and the structure is simple and reliable, and the cost performance is high.

Description

technical field [0001] The invention relates to an automatic device for bundling metal filaments and an automatic method for bundling metal filaments using the device, in particular to the manufacture of conductive bundle brushes in the technical field of rotary electrical connection. Background technique [0002] In the field of rotating connections such as conductive slip rings, the conductive beam brush is one of the key components. The bundle brush is to gather several metal wires of the same length into a bundle, then insert one end into a metal round tube, and press the metal round tube with a certain force, so that one end of the wire bundle is fixed in the metal round tube. The diameter of the metal wire is a few tenths of a millimeter or less, and the length generally ranges from a few millimeters to tens of millimeters; the inner diameter of the metal tube is about 1mm, the wall thickness is about 0.2mm, and the length is generally several millimeters.

AI Technical Summary

Problems solved by technology

[0003] The existing vibrating discharge tray cannot operate such tiny metal wires. For the bundled bundles of metal filaments or similar metal filaments used for making conductive beam brushes, it is mainly done manually at present, which is difficult for workers to operate manually. The labor intensity is high and the work efficiency is very low, which is mainly reflected in the operation of the filaments: 1) Take a certain number of thin metal wires into a bundle by hand or by tweezers. Since the metal wires are very small, it is difficult to pick up and count and rely on skilled operation; 2) When manually inserting a bundle of filaments into a metal round tube, since the inner diameter of the round tube is only slightly larger than the outer diameter of the tow, and the end of the tow is easy to scatter, the insertion process is difficult and requires skilled operation or auxiliary tooling
