An internal sandwich screening equipment for permanent magnet ferrite tiles

Abstract

A permanent magnet ferrite magnetic tile internal sandwich screening equipment, including a magnetic tile transmission device, a magnetic tile charging and demagnetizing tool, and a magnetic tile sandwich detection and shunting device, and the magnetic tile transmission device passes through the magnetic tile charging and demagnetizing tooling and the magnetic tile sandwich The detection and diversion device, one side of the magnetic tile sandwich detection and diversion device is provided with an outlet for sandwich defective products, and the outlet is connected to the storage container for sandwich defective products; the lower part of the tail end of the conveyor belt of the magnetic tile conveying device is provided with a qualified magnetic tile container. The present invention can quickly and automatically screen out defective sandwich products inside the magnetic tiles; the magnetic field source of the charging and demagnetizing tooling is NdFeB permanent magnet ferrite, which has a long service life and obvious energy-saving effect; the size of the charging and demagnetizing tooling can be adjusted according to the size of the magnetic tiles, Wide range of applications.

Description

technical field [0001] The invention relates to a screening device, in particular to a sandwich screening device inside a permanent magnet ferrite tile. Background technique [0002] The key production process of permanent magnet ferrite tiles is: ball milling-forming-sintering-grinding-cleaning-sorting. In the sintering process of the magnetic tile, the problem of the sandwich inside the magnetic tile is prone to occur when the sintering is improper, resulting in a significant drop in the magnetic flux performance of the magnetic tile. [0003] At present, there are two commonly used detection methods in the industry: one is the visual method. After breaking the magnetic tile, observe whether there is a sandwich on the fracture surface with the naked eye. This method is a destructive test and can only be used for random inspection and cannot be fully inspected; Another method is to test whether the magnetic flux value of the product is abnormally low after the magnetic til...

In the sintering process of the magnetic tile, the problem of the inner core of the magnetic tile is prone to occur when the sintering is improper, resulting in a significant drop in the magnetic flux performance of the magnetic tile

[0003] At present, there are two commonly used detection methods in the industry: one is the visual method. After breaking the magnetic tile, observe whether there is a sandwich on the fracture surface with the naked eye. This method is a destructive test and can only be used for random inspection and cannot be fully inspected; Another method is to test whether the magnetic flux value of the product is abnormally low after the magnetic tile is saturated and magnetized, so as to judge whether the magnetic tile has a sandwich. This method can conduct a full inspection of the abnormal batch of magnetic tiles, but the Method screening efficiency is very low and testing costs are high
