AI Technical Summary

Technical Problem

In the existing transformer glue wrapping process, there are problems such as bubbles, lax bonding, raised edges of the finishing section of the glue wrapping and shifting the core I-sheet.

Method used

The EI transformer core glue wrap system is adopted, including a turntable and floating platform. By precisely controlling the movement of linear arms, adsorption blocks, cutting blades and rollers, the tape is tightly adsorbed, wound and cut, ensuring the tight fit of the glue wrap and no curling edges.

Benefits of technology

The problem of lax edges and bonding of the ending section of the glue is solved, reducing the problem of lax bubbles and laminating, and ensuring that the glue is tightly fitted on the outer periphery of the transformer core.

Abstract

The invention discloses an EI type transformer iron core rubber coating system, comprising a horizontal turntable and a floating platform, wherein the horizontal turntable is mounted on a turntable support; a transformer mounting seat is fixed on the upper side of the turntable, and a transformer clamping groove is arranged on the upper side of the transformer mounting seat; a coil skeleton at the lower part of the transformer to be rubber coated can be clamped into the transformer clamping groove; after the rubber coating process of a transformer of the invention is completed, the rubber coating on the outer periphery of the iron core of the transformer is tightly adhered to the outer peripheral surface of the iron core.
