Problems solved by technology
Due to the characteristics of sintering and molding of ferrite sheets, the pressure distribution is uneven, which will cause slight differences in the thickness direction of ferrite sheets; The bending of the ferrite sheet, the double-sided adhesive tape, and the protective film are not tightly combined, and bubbles and wrinkles will be generated during the film covering process, which affects the quality of the product film, resulting in a decrease in the overall product performance and a reduction in the product’s durability.

Abstract
The invention discloses a membrane coating device for ferrite sheets. The membrane coating device comprises a membrane material supplying unit, a membrane coating unit and a substrate supplying unit; the membrane coating unit comprises a magnetic roller, the membrane material supplying unit conveys a first membrane material and enables the first membrane material to be wound on the magnetic roller in a coating mode, the substrate supplying unit sequentially conveys the ferrite sheets and enables the ferrite sheets to sequentially make contact with the magnetic roller, and under the magnetic attraction action of the magnetic roller and the viscosity action of the first membrane material, the ferrite sheets pass through the magnetic roller in a closely attached mode, and the first membrane material is closely pressed to the surface of one side of each ferrite sheet in a coating mode. By arranging the magnetic roller and enabling the first membrane material to be wound on the surface of the magnetic roller in the coating mode, the ferrite sheets and the magnetic roller are closely attached together through the magnetic attraction principle in the process that the ferrite sheets pass through the magnetic roller, therefore, the first membrane material is closely pressed to the surfaces of the ferrite sheets in the coating mode, bubbles generated in the membrane coating process are extruded to be removed, and then the membrane coating quality of the ferrite sheets is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of sheet coating equipment, in particular to a ferrite sheet coating device. Background technique [0002] In recent years, radio frequency identification technology (RFID) and short-range wireless communication technology (NFC) have been more and more widely used, and more and more companies have joined the team of R&D and production of NFC smartphones and NFC wearable devices. middle. The ferrite sintered sheets used in the above technologies are in great demand and have high requirements. How to achieve rapid packaging and obtain a perfect product appearance is very important. [0003] Existing ferrite sheets are usually synthesized by solid-phase synthesis sintering process. Since the sintered ferrite sheet has a large size and a small size in the thickness direction, it is brittle and prone to brittle fracture of the ferrite sheet. Therefore, in the preparation process, it is usually necessary to carr...
