Description

Technical Field

[0001] The utility model relates to the technical field of magnetizers, and mainly relates to a transfer linkage type end face magnetizer. Background Art

[0002] A magnetizer is a device used to magnetize magnetic materials. It is widely used in electronics, electricity, machinery, and other fields, and is crucial in industrial production. Sometimes, magnetizing the end faces of components is necessary. For example, some drive motors require a magnetic terminal with multiple circumferentially arranged poles on the same end face. This change in pole position is used to calculate the number of motor revolutions.

[0003] Flat component end faces are mechanically clamped, making them inconvenient to clamp and subject to wear during the clamping process. Magnetizers have high design requirements, and any slight deviation can affect the actual magnetization direction, which in turn affects the component's back EMF waveform, leading to overall performance degradation. To ensure uniformity and stability of magnetization, the position and orientation of the component must be precisely positioned, and the magnetization time must also be controlled. Existing end face magnetizers are equipped with a pair of transfer assemblies. The first transfer assembly transfers the workpiece from the loading assembly to the magnetization assembly, and after magnetization, the second transfer assembly transfers the workpiece to the unloading assembly. This transfer process is time-consuming, and the magnetization time cannot be accurately controlled. Utility Model Content
