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 tensioning device. device, only one frameless microcoil can be wound at a time, and the production efficiency is low

And the tensioning device volume of existing frameless type microcoil winding machine is too large, can't be installed on the multi-axis frameless type microcoil winding machine simultaneously, can only be suitable for uniaxial frameless type microcoil winding machine, so that The production efficiency of the skeletonless microcoil winding machine is low, and it is difficult to realize mass production
