Description

Halbach magnet automatic feeding machine

Technical Field

The utility model relates to an automatic Halbach magnet feeding machine, and belongs to the technical field of Halbach arrays.

Background

Halbach Array (Halbach Array) is a magnet structure that is an engineered near-ideal structure with the goal of producing the strongest magnetic field with the least amount of magnets. In 1973, the american scholars Mallianson discovered a unique permanent magnet structure when performing assembly experiments on the permanent magnet structure, and called it "Magnetic current". He was not aware of the utility of this structure at that time. In 1979, Klaus Halbach, an american scholars, discovered this special permanent magnet structure and gradually perfected it to finally form the so-called "Halbach" magnet when it used the magnetic field generated by various permanent magnet structures to make electron acceleration experiments. The Halbach magnetic ring combines the radial arrangement and the parallel arrangement of the magnets, if the end effect is neglected and the magnetic permeability of the surrounding magnetic conductive material is regarded as infinite, the permanent magnet structure finally forms a single-side magnetic field (one-side field), which is a remarkable characteristic of Halbach. This feature indicates that the Halbach magnet has a good application value in linear motors.

The halbach magnetic assembly generally comprises a main magnet and a guiding magnet, and the main magnet is one more than the guiding magnet, when the halbach magnetic assembly is assembled, for example, the following figure is taken as an example, three main magnets are pushed onto a tool plate by a simple pusher (the remaining two guiding magnets cannot be directly pushed onto the tool plate due to different magnetizing directions), two guiding magnets need to be manually placed between the two main magnets, as shown in fig. 8, and then the subsequent assembly step is carried out. The halbach magnet assembly is basically realized by semi-automatic or manual placement due to mutual repulsion of the polarities of the magnets, when the magnets are placed manually, the guiding magnets repel and float upwards, and when the width and the height of the guiding magnets are close, the possibility of overturning the guiding magnets exists.
