Description

Technical Field

[0001] The utility model relates to the technical field of Halbach magnet groups, in particular to a cache transfer turntable of a Halbach magnet group. Background Art

[0002] The Halbach magnet group is a magnet structure with a special shape. Its design idea is to combine multiple magnets of the same shape but different magnetization directions into a ring magnet to enhance the uniformity and stability of the working surface or the center magnetic field. The permanent magnet motor using the Halbach magnet group structure has an air gap magnetic field that is closer to a sinusoidal distribution than the traditional permanent magnet motor. When the amount of permanent magnet material is the same, the air gap magnetic density is larger and the iron loss is smaller. In addition, the Halbach magnet group ring array is also widely used in permanent magnet bearings, magnetic refrigeration equipment, magnetic resonance equipment and other equipment. When preparing the Halbach magnet group, people need to use a turntable to transfer and transport the magnetic strip components that make up the Halbach magnet group.

[0003] However, the traditional turntable has the following disadvantages:

[0004] Common turntables on the market are all for transferring, picking up, placing and assembling single magnets, but it is difficult to hold, transfer and fix the position of Halbach magnet arrays. In addition, when assembling Halbach magnet groups, the magnet arrays are usually manually placed on metal sheets. There is no effective operation method, which reduces the assembly efficiency of Halbach magnet groups. Utility Model Content

[0005] The purpose of the utility model is to provide a cache transfer turntable of a Halbach magnet group to solve the problem mentioned in the background technology that the common turntables on the market are all for the transfer, placement and assembly of single magnets, while the retention, transfer and position fixation of the Halbach magnet array are difficult, and the Halbach magnet group is generally assembled by manually working the magnet array on the metal sheet, and there is no effective working method, which reduces the assembly efficiency of the Halbach magnet group.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Halbach magnet group cache transfer turntable, comprising a non-magnetic turntable body, a plurality of grooves are opened on the side of the non-magnetic turntable body, a plurality of metal strips are fixedly installed inside the grooves, a plurality of reverse magnet groups are glued and connected inside the metal strips, a plurality of non-magnetic cover plates located above the grooves are provided on the top of the non-magnetic turntable body, and the reverse magnet group mainly functions to attract the Halbach magnet group that enters and exits the non-magnetic turntable body for caching.

[0007] Preferably, fixing holes are provided on both sides of the top ends of the plurality of non-magnetic cover plates, and the user screws screws through the fixing holes to fix the non-magnetic cover plates on the non-magnetic turntable body.

[0008] Preferably, a steering hole is provided in the middle of the top end of the non-magnetic turntable body, and the non-magnetic turntable body is connected to the rotating shaft through the steering hole, so that the non-magnetic turntable body can be driven to rotate.

[0009] Preferably, four limiting holes arranged in a rectangular shape are provided on the top of the non-magnetic turntable body, and the non-magnetic turntable body is fixed at the installation location through the limiting holes.

[0010] Preferably, the bottom ends of several of the non-magnetic cover plates are in contact and connected with the side directly opposite to the non-magnetic turntable body. After the non-magnetic cover plates are in contact with the non-magnetic turntable body, the non-magnetic cover plates limit the height when feeding and discharging materials from the top.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting the grooves and dividing the turntable into a number of equal grooves, a corresponding magnet array with opposite polarity is adhered and fixed to the bottom of the groove, so that the Halbach magnet array can be sucked and held when pushed in, and a non-magnetic cover plate is provided on the upper edge of the groove to ensure the stability of the Halbach magnet when it is transferred in and out of the groove and to prevent any possible warping problems during the process.
