Magnetic core blank for OLED backlight source

Abstract

The invention discloses a magnetic core blank for an OLED backlight source. The blank comprises a blank bottom plate, a middle column arranged on the upper surface of the blank bottom plate and side columns symmetrically arranged on the two sides of the middle column, the middle column extends in the width direction of the blank bottom plate, and the side columns are located at the two ends of theblank bottom plate in the length direction. A transition section is arranged between the outer side walls of the side columns and the blank bottom plate and comprises an arc-shaped section and a vertical section from top to bottom, and the arc-shaped section is bent inwards from top to bottom. According to the magnetic core blank, the transition section is arranged, so that a gap is formed between the side columns and the blank bottom plate, better impurity removal of the blank is facilitated in the sintering process, meanwhile, flowing of airflow is facilitated, the magnetic core blank is heated more uniformly in the sintering process, and meanwhile, in the pressing process, die damage and blank edge generation caused by direct chamfering can be reduced, rubber coating and assembling offormed products are facilitated, rubber belts are not prone to being cut, the working efficiency is improved, and meanwhile the reject ratio is reduced.

Description

Technical field[0001]The invention relates to the technical field of magnetic core blanks, in particular to a magnetic core blank for OLED backlight sources.Background technique[0002]Magnetic core components are important components of LED or OLED backlights. In order to meet the current ultra-thin requirements, the magnetic core must be thinner. The magnetic core needs to be fired in a fixed mold during production. In the prior art, the magnetic core blank During the pressing process, the bottom of the part is usually right-angled or beveled. During the pressing process, the mold is easily damaged, the life is short, and the finished blank is easy to produce blank front. Therefore, how to improve the quality of the product and extend Mold life is a problem that those skilled in the art are committed to solving.Summary of the invention[0003]The purpose of the present invention is to overcome the shortcomings of the prior art and provide a magnetic core blank for OLED backlight.[0004...

AI Technical Summary

Problems solved by technology

[0002] The magnetic core part is an important part of the LED or OLED backlight source. In order to meet the current ultra-thin requirements, the magnetic core must be thin to a certain extent. When the magnetic core is produced, it needs to be fired in a fixed mold. In the prior art, the magnetic core blank During the pressing process, the bottom is usually at right angles or chamfered. During the pressing process, the mold is vulnerable, the life is short, and the blank is easy to produce a blank front. Therefore, how to improve the quality of the product and prolong the Die life is a problem that those skilled in the art are committed to solving
