Abstract
The invention provides a manufacturing device and manufacturing method for molding inductor elements, and an application. The manufacturing device mainly includes a mold and at least one magnetic force generation unit, especially, the mold has at least one accommodating groove to accommodate coils; after the accommodating grooves are filled with molding materials mixed with ferromagnetic powder, magnetic force can be provided to the accommodating grooves by utilizing molding modules; and each molding material monomer can move downward in the accommodating grooves under the effect of the magnetic force, so that a molding effect can be achieved. The using of any molding tools is not needed during the whole process of generating molding inductors by applying the manufacturing device or method, so that friction force generated between the molding materials and the inner walls of the accommodating grooves can be greatly reduced; and damage to enameled wires of the coils caused by excessivepressure of the molding tools cannot occur.
Description
technical field [0001] The present invention relates to the technical field of passive components, in particular to a manufacturing device and method for molding inductive components using magnetic force instead of conventional mold pressure and its application. Background technique [0002] Inductors are one of many circuit components, and their main functions include: preventing electromagnetic wave interference, shielding electromagnetic radiation, filtering noise in current, and suppressing instantaneous current and stabilizing current. In terms of structure, it can be divided into wire-wound, molding, multilayer, and thin-film. At present, molded inductors are widely used in precision electronic products, such as smart phones, mobile devices, Netcom, and automotive electronics. [0003] Figure 1A and Figure 1B A process schematic showing a molded inductor. Passive component engineers who are familiar with the design and manufacture of molded inductors should know t...
