Magnetic printing device

Abstract

The invention discloses a magnetic printing device, which includes a magnetic yoke, a coil, a power supply, a driving mechanism, and a control module. The two ends of the magnetic yoke are equipped with magnetizing poles. The two magnetizing poles are arranged opposite to each other along the Z axis and a magnetic printing work area is formed between the two magnetizing poles. The coil is arrangedon the magnetic yoke. The power supply provides the coil with currents in the forward and reverse directions so that magnetic fields in the forward and reverse directions are alternately generated inthe magnetic printing work area. The driving mechanism drives a workpiece to move along the X and Z axes in the magnetic printing work area. The control module instructs the power supply to output aforward or reverse current according to a magnetization pattern required by the workpiece, so that a forward or reverse magnetic field adaptive to the magnetization pattern is generated in the magnetic printing work area. The magnetic printing device provided by the present invention can magnetize the workpiece to form a multi-pole magnet and can magnetize a magnetic pole region with regular and irregular patterns. The magnetized multi-pole magnet has a small size and uniform magnetic pole distribution.

Description

technical field [0001] The invention relates to the field of magnetization technology, in particular to a magnetic printing device. Background technique [0002] A multi-pole magnet means that the magnet has multiple magnetic poles on one surface. The traditional multi-pole magnet is formed by splicing multiple magnets separately, which makes the overall size of the multi-pole magnet larger and it is difficult to make the pole angle accurately. It is difficult to achieve uniform quality of the entire magnetic ring, which makes the dynamic balance of the magnetic ring poor. [0003] Although there are multiple magnetizing yokes installed on the magnetic field generating device to realize multi-pole magnetization on the market, this method of multi-pole magnetization will cause a large circuit load and prone to uneven distribution of magnetic poles. .

[0003] Although there are multiple magnetizing yokes installed on the magnetic field generating device to realize multi-pole magnetization on the market, this method of multi-pole magnetization will cause a large circuit load and prone to uneven distribution of magnetic poles.

Moreover, the magnetic pole areas of different magnetic poles of multi-pole magnets on the market are all regular shapes, resulting in a small application range. When making magnetic poles in irregular areas, a correspondingly shaped yoke is required for magnetization, resulting in poor versatility. higher production costs
