Title:
MAGNETIC FORMING DEVICE FOR PREPARING ELECTROMAGNETIC SHIELDING SEALING STRIP
Document Type and Number:
WIPO Patent Application WO/2022/206018
Kind Code:
A1
Abstract:
Disclosed in the present invention is a magnetic forming device for preparing an electromagnetic shielding sealing strip, comprising an electric control cabinet, a case, a semi-closed yoke, a conductive coil, and a height adjustment assembly. A bridge rectifier, a transformer, a touch screen, an ammeter, a silicon controlled rectifier, and a PLC controller are provided in the electric control cabinet; the case semi-covers the semi-closed yoke; the whole semi-closed yoke is approximately C-shaped, and comprises an upper yoke, a lower yoke, and a connecting yoke that are horizontally arranged; the height adjustment assembly comprises a positioning frame, a guide rod/guide sleeve assembly, a screw rod/screw sleeve assembly, and a distance adjustment plate movably connected to the lower end of a screw rod. The magnetic forming device can pull ferromagnetic conductive particles by controlling the magnetic flux intensity of a magnetic field by means of the current size; an electric control parameter can be rapidly obtained by performing mathematical modeling and fitting by means of a linear regression model after regulating a current parameter and a yoke distance parameter and performing multiple sets of sampling training; and an electromagnetic shielding sealing strip having an approximate "Δ" shape or approximate "n" shape is obtained according to the change in current intensity, and has wide applicability.
