Stator coil binding device

Abstract

The invention discloses a stator coil binding device, and belongs to the technical field of coil binding machines. An existing coil binding device can only bind a binding coil on a copper coil of a stator at a time, and if a plurality of binding coils need to be bound on the copper coil at a time, the operation cannot be finished, so that the coil binding efficiency is low. A coil clamping mechanism can clamp the binding coil and cut the tail coil part of the previous binding coil to carry out the next round of coil binding, so that the plurality of coils can be bound on the same copper coil at a time, and the coil binding efficiency is high. A fixed connection piece abuts against the edge, not provided with the coil, of the stator or / and the side wall of the stator, so that the stator is fixed; the fixed connection piece is not in contact with the coil, so that the deformation of the coil cannot be caused, and a coil hooking gap in the lower end part of the coil is not influenced; the structure is simple and practical; the scheme is feasible; the prejudice of the prior art is broken; and the conception is ingenious. A pressing piece which can abut against the binding coil is arranged on a pole in a penetrating mode; and the friction resistance provided by the pressing piece is utilized for controlling the tension of coil binding, so that a relatively stable coil binding tension force can be provided.

Description

technical field [0001] The invention relates to a stator wire binding device, which belongs to the technical field of wire binding machines. Background technique [0002] Chinese patent (Notice No. CN206743066U) discloses a motor stator wire binding device, including a binding wire up and down drive mechanism, a crochet needle advance and retreat mechanism, a crochet needle rotation mechanism, a thread head up and down mechanism, a thread head swing mechanism and a control device; The above-mentioned control device is electrically connected with the upper and lower driving mechanism of the binding thread, the advance and retreat mechanism of the hook thread needle, the rotation mechanism of the hook thread needle, the upper and lower mechanism of the thread outlet and the swing mechanism of the thread outlet.

Problems solved by technology

[0003] The above scheme can only bind one winding coil on the stator copper coil at a time. If it is necessary to bind multiple winding coils on the copper coil at one time, it cannot be completed, resulting in low binding efficiency; at the same time, the above scheme does not disclose how to ensure the tension of the binding wire. The tightening force meets the requirements of the wire binding machine, resulting in unclear scheme or lack of necessary technical features
