Tensioning device of frameless micro-coil winding machine

Abstract

The invention discloses a tensioning device of a frameless micro-coil winding machine. The device comprises a rack, a bracket fixed on the rack, a mounting platform, a first flat plate, a second flatplate, a wire inlet mechanism and a wire outlet mechanism, a guide rail and a first motor are arranged on the mounting platform; a moving block is arranged on the guide rail; the moving block is connected with a first motor; the first flat plate is vertically arranged and fixedly arranged on the bracket; the second flat plate is vertically arranged and fixedly arranged on the moving block; the wire inlet mechanism comprises n wire inlet assemblies, each wire inlet assembly comprises a rotating part, a bobbin shaft, a bobbin and a first guide wheel, the wire outlet mechanism comprises an electric control servo proportional valve and n wire outlet assemblies, and each wire outlet assembly comprises an air cylinder, a rotating arm, a cam bearing follower, a second guide wheel, a third guide wheel, a fourth guide wheel and a fifth guide wheel. The device has the advantages of being compact in structure, small in size and capable of being used for a multi-axis coil winding machine, improving the production efficiency of the frameless micro-coil and achieving large-batch production of the frameless micro-coil.

Description

technical field [0001] The invention relates to a tensioning device, in particular to a tensioning device for a frameless microcoil winding machine. Background technique [0002] The enameled wire used in the frameless microcoil is a self-adhesive polyamideimide enameled wire, which is formed by utilizing the self-adhesive property of the self-adhesive polyamideimide enameled wire. Self-adhesive polyamideimide enameled wire has a temperature resistance rating of 220°C, but its cross-sectional area is only 0.0036mm 2 ~0.034mm 2 between. Self-adhesive polyamide-imide enameled wire is different from ordinary enameled wires wound around motors or transformer coils, and has unique material properties. Therefore, a unique tensioning device is required to ensure self-adhesive polyamide-imide The tension of the amine enameled wire during the winding process is straight. [0003] The tensioning device of the existing frameless microcoil winding machine is generally realized by an...

Problems solved by technology

The pay-off method of the mechanical tensioner or the electronic tensioner is passive and free, so the volume of the mechanical tensioner or the electronic tensioner is relatively large, and the installation layout is not compact enough

The multi-axis frameless microcoil winding machine needs to install multiple tensioning devices to realize the tensioning and straightening of multiple coil winding processes, and the production efficiency is high. The single-axis frameless microcoil winding machine can only install one
