Method for manufacturing magnet module

Abstract

The present invention relates to a method for manufacturing a magnet module. A method for manufacturing a magnet module, according to an embodiment of the present invention, may comprise injection-molding a magnet module comprising a plurality of non-magnetized magnets arranged in a straight line and magnetizing the non-magnetized magnets mounted on the injection-molded magnet module. The injection-molding may comprise mounting non-magnetized magnets on a first portion of a mold consisting of at least two casts having inner portions molded to fit the outer appearance of a magnet module, the first portion forming a frame of the magnet module, injecting resin in a liquid state into the mold, and separating, when the resin is hardened, the mold from the hardened resin, thereby injection-molding the magnet module frame. In addition, before the resin in a liquid state is injected into the mold, a metal plate may be mounted on a second portion of the mold, the second portion forming the baseof the magnet module. Pins for fixing the non-magnetized magnets may protrude from the at least two casts. Accordingly, the manufacturing process of a magnet module is simplified, thereby increasingthe manufacturing efficiency.

Description

technical field [0001] The present invention relates to a method of manufacturing a magnet module, and more particularly, to a method of manufacturing a magnet module used in a linear motor and composed of a plurality of magnets arranged in a forward direction by injection molding. Background technique [0002] A linear motor, that is, a linear motor, has a structure in which thrust is generated between a mover and a stator that face each other in a straight line. In the permanent magnet linear motor, a permanent magnet is arranged on either side of the mover and the stator, and a multi-phase alternating current is applied to the other side, so that the electromagnetic force acts between the two to generate a thrust in a certain direction. [0003] Most of the existing linear motors adopt a structure in which the magnetic flux from the salient pole of the armature core passes through the permanent magnet and forms a closed magnetic circuit through the magnetic core to genera...

Problems solved by technology

[0009] However, since the magnetic force of the permanent magnet is very strong, two magnets stick to each other, and the magnets stuck to each other are difficult to detach, so there is a process of confirming the magnetization direction which is rather cumbersome and the sticky coating applied to the inside of the opening or the edge of the magnet. The escape of the mixture causes the appearance of the assembled magnet module to be rough and other problems, so that there are many working procedures related to the assembly of the magnet module, which is not only cumbersome, but also reduces the working efficiency
