Electromagnetic induction coil panel and manufacturing process thereof

Abstract

The invention discloses an electromagnetic induction coil panel, which comprises a coil winding, a plastic bracket and a plurality of magnetic stripes, wherein the coil winding is wound in a wire casing on the upper surface of the plastic bracket; the plurality of magnetic stripes are arranged in a plurality of accommodation grooves formed on the lower surface of the plastic bracket respectively; and one or more positioning lug bosses are arranged on the two sides of each of the wire casing and the accommodation grooves, and are hot-pressed to embed the coil winding into the wire casing and partially wrap the magnetic stripes. The manufacturing process comprises the following steps of: 1, winding the coil winding in the wire casing on the upper surface of the plastic bracket; 2, clamping the magnetic stripes in the accommodation grooves on the lower surface of the plastic bracket; and 3, simultaneously heating the two surfaces of the plastic bracket to heat, soften and deform the positioning lug bosses on the two sides of each of the wire casing and the accommodation grooves, and pressing the lug bosses to embed the coil winding into the wire casing and integrate the coil winding and the wire casing and partially wrap the magnetic stripes. According to the manufacturing process, a process flow is simplified and working environment is clean and sanitary; and the coil panel has a secure and stable structure.

Description

technical field [0001] The invention relates to an electromagnetic induction coil disk and a manufacturing process thereof, and belongs to the improvement technology of the electromagnetic induction coil disk and the manufacturing process thereof. Background technique [0002] The electromagnetic induction heating cooker sold on the market at present, its coil disk includes coil winding, support and magnetic strip, when coil disk is assembled, coil winding is bonded in the wire slot on the upper surface of support by adhesive, and magnetic strip is glued by glue. The bonding agent is bonded in the accommodating groove on the lower surface of the bracket, and after the coil winding and the magnetic strip are bonded, the coil disk is baked and shaped. However, under the influence of factors such as transportation and high temperature, the coil windings and magnetic strips of the above-mentioned structure are prone to deformation and falling off, resulting in potential safety h...
