A method of laser forming ferrite products from glue surface of ferrite material

Abstract

The invention relates to a method for forming a ferrite product from the glue face of a ferrite material through lasers. The glue face of the ferrite material is cut through the lasers, and the ferrite product is formed. Before laser cutting, a PET film of the surface of the ferrite material is glued with a layer of PET single-face silica gel protective film, the glue layer is glued with a layer of PET release protective film after the single-face gel protective film of the ferrite material is peeled off, and the PET release protective film is cut into the ferrite product through the lasers. Compared with the prior art, by the adoption of the method, the cut ferrite surface is free of dirt, scratches, iron leakage, particles, burnt edges and other bad phenomena of the appearance, and the surface of the ferrite product is same as the surface of the ferrite material before cut without any change after the PET single-face silica gel protective film is peeled off; and during laser cutting, the PET single-face silica gel protective film is not cut through, the PET single-face silica gel protective film is peeled off after laser cutting, and waste, generated during laser cutting, in holes is bonded to the PET single-face silica gel protective film to be removed together, and the process is saved.

Description

technical field [0001] The invention relates to a method for forming a ferrite product, in particular to a method for laser forming a ferrite product from the rubber surface of a ferrite material. Background technique [0002] Ferrite is a metal magnetic material with ferromagnetism. Because of its large resistivity and high dielectric properties, ferrite materials can isolate the absorption of the antenna magnetic field by metal materials and increase the magnetic field strength of the antenna. Effectively increase the communication sensing distance, and the ferrite material has the characteristics of low cost, good temperature stability, strong hardness, and good corrosion resistance. Therefore, it has been widely used in the field of short-range wireless communication in recent years. [0003] Existing ferrite material structures such as figure 1 As shown, it includes a ferrite layer 3, a surface PET film 4 consolidated on the upper surface of the ferrite layer 3, an adh...

Problems solved by technology

However, when conventional laser cutting ferrite products including the method disclosed in the comparative patent, after the ferrite material is laser cut, due to the ultra-high temperature of the laser, iron filings, foreign matter and dirt will be left on the surface of the ferrite. dirt, etc., it is necessary to manually wipe the foreign matter and dirt on the surface with a dust-free cloth or a brush. On the one hand, it is easy to cause scratches on the ferrite surface, iron leakage, and unclean particle foreign matter treatment, which will increase the defect rate. On the other hand, it is necessary to increase the surface treatment process after cutting, the production efficiency is too low, and the production link and production cost are increased.
