Problems solved by technology

[0003] In the field of magnetization of NdFeB permanent magnets, the existing technology generally adopts manual magnetization for permanent magnets. Generally, 3 people are needed, one person is responsible for magnetization, and one person is responsible for inspecting the magnetized pieces piece by piece. Whether the magnetic sheet is qualified or not requires one person to be responsible for extracting the qualified magnetic sheet. The existing technology not only has many workers, but also has high labor intensity and low production efficiency.

Embodiment Construction

[0048] The present invention will be further described below in conjunction with specific embodiments, but it should be noted that the embodiments of the present invention are only used to illustrate the technical solutions of the present invention, and not to limit the present invention.

[0049] It needs to be pointed out that the following description is based on the circular NdFeB permanent magnet as an example. For example, preferably, the outer diameter of the circular permanent magnet is 13.4mm, the inner diameter is 5.8mm, and the thickness is 0.5-2mm . But those skilled in the art should realize that the present invention is not limited thereto, and the device and method of the present invention can also magnetize permanent magnets of other arbitrary shapes, such as rectangles, triangles, trapezoids or other irregular shapes. Of course, the present invention can also be applied to other permanent magnets except NdFeB.

Abstract

The invention provides automatic magnetizing apparatus and method of two poles of a magnetic sheet. The magnetizing apparatus comprises a main stand, a charging part, a feeding part, a loading magnetic head fixing part, an upper magnetic head fixing part and a taking-out part, wherein the main stand is used for supporting each part of the apparatus; the charging part is installed on the main stand and is used for storing the magnetic sheet to be magnetized; the feeding part is installed on the main stand and is used for conveying the magnetic sheet to be magnetized to a magnetizing region from the charging part; the loading magnetic head fixing part is installed on the main stand and is provided with a lower magnetic head, and the magnetizing region for magnetizing the magnetic sheet to be magnetized is arranged at the middle part of the lower magnetic head; the upper magnetic head fixing part is provided with an upper magnetic head and is used for pressing the magnetic sheet conveyed by the feeding part between the upper magnetic head and the lower magnetic head, and the magnetic sheet to be magnetized can be magnetized in the state; and the taking-out part is used for taking out the magnetized magnetic sheet through a taking-out apparatus and putting the magnetized magnetic sheet into a storing apparatus of the loading magnetic head fixing part. The invention realizes the automatic magnetization of the two poles of the magnetic sheet, improves the production efficiency, and saves the manual labor and the cost.

Description

technical field [0001] The invention belongs to the field of magnetization of permanent magnets. More specifically, the invention relates to a device for bipolar automatic magnetization of a magnetic sheet and a magnetization method using the device. Background technique [0002] In recent years, the application and development of neodymium iron boron (NdFeB) permanent magnet materials is very rapid. NdFeB permanent magnet materials are mainly made of rare earth metals such as neodymium (Nd), iron and boron through powder metallurgy process. As the strongest magnetic material at present, it has been widely used in electroplating devices, machinery, medical treatment, automobiles and many other fields, and its application prospects are very broad. [0003] In the field of magnetization of NdFeB permanent magnets, the existing technology generally adopts manual magnetization for permanent magnets. Generally, 3 people are needed, one person is responsible for magnetization, an...
