Description
Technical Field
The invention relates to a motor rotor device, in particular to a motor rotor magnetic steel pasting device and a pasting method thereof.
Background
In the motor manufacturing industry, the rotor of the surface-mounted inner rotor permanent magnet motor consists of a shaft, a rotor disc and magnetic steel, wherein the magnetic steel is uniformly distributed on the rotor disc on the circumference, and for a longer rotor, the rotor is generally divided into a plurality of sections. The rotor processing of the surface-mounted inner rotor permanent magnet motor requires that the magnetic steel is uniformly distributed on the rotor disc by glue according to the circumference. The existing magnetic steel pasting modes generally have two modes, the first method is to use automatic magnetic steel pasting equipment, glue is applied to magnetic steel by the equipment, the magnetic steel is clamped, the first magnetic steel is pasted on a rotor disc in a pneumatic or electric mode, then the rotor disc is rotated by a certain angle by using an automatic indexing device, the second magnetic steel is pasted, and generally, a plurality of the equipment can be pasted at the same time in the circumferential direction. The automatic magnetic steel pasting device has the defects of complex structure, high manufacturing cost, complex manufacturing period and low cost in trial production and small batch. Meanwhile, if the magnetic steel is pre-magnetized, the second magnetic steel can be stuck after the glue is solidified after a period of time after the first magnetic steel is stuck due to the attraction force and the repulsion force between the magnetic steels, and for the rotor with multiple stages, the magnetic steel on the circumference is difficult to be stuck completely at one time, so that the efficiency cannot be improved.
The second method is to make the rotor disk into a sheet form, and laminate a plurality of sheets, because the sheets are directly punched by standard electrical steel, the thickness of the electrical steel is generally below 0.5m, and therefore, the thickness of the sheets is generally below 0.5 mm. The circumference of the punching sheet is provided with a convex groove which has the function of automatic indexing and can be directly stuck to the surface of the punching sheet after the magnetic steel is coated with glue. The disadvantage of rotor punching is the need for die opening, which is also costly in both pilot and small volume production stages. Meanwhile, as lamination coefficients exist in the punching sheets, for a longer rotor, all the punching sheets are required to be arranged on a shaft, and then the magnetic steel can be pasted after the two ends are tensioned by end plates, otherwise, the thickness of the punching sheet group in the tensioning process is reduced, so that the pasted magnetic steel is loose, and therefore the magnetic steel cannot be pasted in sections. For the pre-magnetized magnetic steel, the magnetic steel can be loosened after being fixed for a period of time due to the repulsive force of the axial front and rear magnetic steel, and the efficiency is low. Therefore, in the stages of trial production and small-batch production of the motor rotor, it is particularly necessary to design a magnetic steel pasting device and method which have the advantages of uniform magnetic steel distribution, low cost and high efficiency and can fast paste pre-magnetized magnetic steel.
