Abstract

The invention discloses a device and a method for avoiding sintering adhesion of a magnetic core. The device for avoiding sintering adhesion of the magnetic core comprises a vibration disc, a heat preservation cover located above the vibration disc, a material guide groove located in one side of the vibration disc, a heater located below the heat preservation cover and a material collecting barrel. The vibration disc comprises a rack, a tray fixedly installed at the upper end of the rack, a vibrator fixedly installed on the lower end face of the tray, and a discharging groove fixedly installedon the outer side wall of the rack and communicated with the tray. And a buffer piece is arranged in the middle of the tray. The method for avoiding sintering adhesion of a magnetic core comprises the following steps: 1) pouring aluminum powder into the vibration disc; 2, conveying the magnetic core to the middle part of the tray to be in contact with aluminum powder; 3, vibrating and dischargingby the magnetic core through the vibrating disc; 4, entering sintering furnace for sintering. The device and method for avoiding sintering adhesion of the magnetic core have the advantages of being simple in structure, convenient to operate, low in cost, high in efficiency and high in product percent of pass.

Description

technical field [0001] The invention relates to the technical field of preparation of electronic components, in particular to a device and method for avoiding magnetic core sintering and adhesion. Background technique [0002] High-performance nickel-zinc soft magnetic ferrite core components have the characteristics of low loss, high saturation magnetic flux density and high efficiency at high frequencies, and various inductors, transformers, choke coils, filter Inverters, inverters, etc., are widely used in smart home appliances, communications, electric light sources, automotive electronics, photovoltaic new energy and other fields. [0003] At present, the production process of nickel-zinc ferrite cores generally includes powder making, molding, sintering, grinding, sorting, and packaging. In order to reduce the production cost, the magnetic core generally adopts stack firing or stack firing during the sintering process to improve the sintering efficiency. However, dur...
