Problems solved by technology

[0002] Due to the small size of the Φ10*2 product, the original magnetization process needs to pack the product into a long strip, and it takes 20 hours to magnetize after packaging 50,000 pieces. Magnetization is once every 5-7 strips, and it takes time to unpack the package. plenty of time
In addition, because the original product is long when it is magnetized, when it is placed in the magnetization coil for magnetization, in some cases, some products will be exposed to the magnetization coil, resulting in unsaturated magnetic field phenomenon.

Embodiment Construction

[0011] A detailed description will be given below of specific embodiments of the present invention.

[0012] Product specification: Φ10*2 630,000 pieces

[0013] Product grade: N40

[0014] Plating Type: Nickel Copper Nickel.

[0015] Due to the small size of the Φ10*2 product, the original magnetization process needs to pack the product into a long strip, and it takes 20 hours to magnetize after packaging 50,000 pieces. Magnetization is once every 5-7 strips, and it takes time to unpack the package. plenty of time.

[0016] The subsequent 580,000 pieces adopt the improved magnetization packaging method, which includes the following steps:

[0017] 1) Place the NdFeB small disc material in an open tin box;

[0018] 2) Then place the tin box in the magnetized coil for magnetization;

[0019] 3) The magnetized products are magnetically attracted to each other and form strips, which are directly packed into boxes.

[0020] The improved scheme has significantly improved the ...

Abstract

The invention relates to a magnetizing method for a neodymium-iron-boron product and particularly relates to a magnetizing packaging method for a small neodymium-iron-boron circular piece material. The method comprises the following steps of: 1) placing the small neodymium-iron-boron circular piece material in an open iron-skin box; 2) placing the iron-skin box in a magnetizing coil and magnetizing; and 3) directly bagging and boxing the magnetized products which are mutually adsorbed to be strip-shaped due to magnetism. According to the invention, the products are not wrapped to be strips by paper, so that a process of opening the paper package is omitted, and the working efficiency is slightly increased by about 30%. Although the paper for packaging the products is recycled, the paper is still lossy after being used for many times, and by the improvement, the paper package is omitted, so that the waste of paper is saved, and certain cost is reduced. The magnetized products are stored in a turnover box, and can be directly bagged and boxed, so that labour cost is saved, and the magnetizing is more adequate simultaneously.

Description

technical field [0001] The invention relates to a magnetizing method for NdFeB products. Background technique [0002] Due to the small size of the Φ10*2 product, the original magnetization process needs to pack the product into a long strip, and it takes 20 hours to magnetize after packaging 50,000 pieces. Magnetization is once every 5-7 strips, and it takes time to unpack the package. plenty of time. In addition, because the original product is long when it is magnetized, when it is placed in the magnetization coil for magnetization, in some cases, some products will be exposed to the magnetization coil, resulting in insufficient saturation and weak magnetic field. In this improvement, the product is placed in a circular tin box before magnetization. Since the tin box is completely covered by the coil, there will be no phenomenon of weak magnetism caused by unsaturated magnetization of the product during magnetization. Contents of the invention [0003] In order to sol...
