Ultrathin coil tool jig, preparation method and preparation equipment thereof

Abstract

The invention discloses an ultra-thin coil tool jig, a preparation method and preparation equipment thereof. The ultra-thin coil tool jig comprises a locking piece, a cover plate, a mold core, a moldsleeve, a bottom plate and a heat conduction piece. One end of the locking piece penetrates through the cover plate to be detachably connected with the mold core, the mold core is sleeved with the mold sleeve, jackscrews used for locking and unlocking the position between the mold sleeve and the mold core are arranged on the peripheral side of the mold sleeve, the bottom plate is fixedly connectedwith the side, away from the cover plate, of the mold sleeve, and the mold core is connected with an external heat source through the heat conduction piece. In the coil winding state, the mold sleeveis matched with the mold core through the jackscrew and used for adjusting and locking the distance between the cover plate and the mold sleeve, the distance between the cover plate and the mold sleeve is the winding breadth of the coil, and the mold core is a winding center shaft of the coil; and in a coil pressing state, the jackscrew is in an unlocked state, and the cover plate and / or the bottom plate are / is a pressing plate used for pressing the wound coil. The method has the technical characteristic of high production efficiency, and the prepared coil has the advantages of small thickness, strong universality, good heat dissipation performance, low cost and the like.

Description

technical field

[0001] The invention belongs to the technical field of coil preparation, and in particular relates to an ultra-thin coil tooling fixture, a preparation method and a preparation device. Background technique
