DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming an attraction surface of a sheet-like magnet, and uses a multi-pole magnetized sheet-like magnet to form a net-like magnetic pole on the surface without using a magnetizing facility. Provide a way.

2. Description of the Related Art Conventionally, when a multi-polar magnetized sheet magnet is used as a surface material of a board, a wall surface, or the like, and the multi-polar magnetized magnet is attracted and moved on its attracting surface, it is required to be a multiple of the magnetized pitch. Can be translated precisely in one of the vertical or horizontal directions, ie N ·
The S pole was limited to the direction orthogonal to the parallel linear magnetic poles alternately arranged in parallel.

On the other hand, when the magnet having the net-shaped magnetic poles is attracted to the attracting surface having the net-shaped magnetic poles, the magnet can be moved in parallel in the vertical and horizontal directions at precise intervals. When the magnet is attracted, it can slide smoothly in the vertical or horizontal direction. Therefore, magnets having net-shaped magnetic poles are used more widely and are more versatile than multi-pole magnetized magnets.

Conventionally, as a method of forming a net-shaped magnetic pole on a magnet surface, a method of magnetizing twice has been adopted. For example, after the primary magnetizing is performed on the sheet magnet at a magnetizing pitch of 2.5 mm, the direction of the magnet is changed by 90 degrees, and the secondary magnetizing is performed with a lower magnetic force than the primary magnetizing. That is, when magnetized in a lattice, a net-shaped magnetic pole is formed on the magnet surface.

In the above, an example in which primary and secondary magnetizations are performed by the same magnetization yoke as a method of forming a net-like magnetic pole has been described. However, the magnetic poles formed in the step of magnetizing the sheet magnet are orthogonal. There is also a method of arranging two magnetized yokes so as to perform primary and secondary magnetization.

FIG. 4 is a view showing the state of magnetic poles detected by applying a magnetic pole detection film to an attracting surface having net-shaped magnetic poles. FIG. 4 (A) is a full-scale plan view in the case of a magnetization pitch of 2.5 mm. (B) is a partially enlarged view.

When the magnet A having the net-shaped magnetic poles slides on the attracting surface having the net-shaped magnetic poles, the magnets A are repeatedly attached and repelled in both the vertical and horizontal directions as shown by arrows A to D. The translation can be performed precisely every multiple of the magnetic pitch. At this time, since the magnetic pole width is narrow, even if the repulsive action works, the attracting action with the next magnetic pole works immediately, so the magnet does not drop at the time of repulsion and translates at regular intervals like intermittent motion Can be.

Further, when the multi-polarized magnet B is slid in the longitudinal direction of the parallel linear magnetic poles on the attracting surface having the net-shaped magnetic poles, the magnets B slide smoothly without any displacement as running on the rails. By simply changing the direction of the magnet B, the magnet B can slide on the attracting surface in either the vertical or horizontal direction.

When the multi-pole magnetized magnet B slides, the narrow portion of the net-shaped magnetic pole on the attracting surface may correspond to the same pole, but since the magnetic flux density is extremely lower than that of the bulge portion,
In operation, it can slide smoothly without feeling any repulsive force (see FIG. 4B). Thus, the attracting surface having the net-shaped magnetic poles is compared with the attracting surface of multi-polar magnetized and the iron plate,
The magnet can be freely moved as needed.

[0010]

In order to form the net-shaped magnetic pole on the surface of the sheet-shaped magnet as described above, the primary and secondary magnetizing operations are performed by setting the parallel linear magnetic poles to be perpendicular to each other. I had to. For this reason, it is necessary to arrange two magnetized yokes having different magnetic pole forming directions, or to change the direction of the sheet magnet when only one magnetized yoke is used. It could be formed only at a certain place, and the net-shaped magnetic pole could not be easily formed from the viewpoint of work and equipment.

The present invention does not require a magnetizing facility, and provides a method capable of forming a net-shaped magnetic pole on the spot when an adsorption surface having a net-shaped magnetic pole is required at a construction site or product processing. Is what you do.

[0012]

According to the present invention, in order to solve the above-mentioned problems, two multipole-magnetized sheet-like magnets are replaced by parallel linear magnetic poles in which N and S poles are alternately arranged in parallel. By arranging and laminating the magnets in directions orthogonal to each other, it is possible to form an attraction surface having net-shaped magnetic poles formed on the surface of the magnet.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Two multi-pole magnetized sheet magnets having parallel linear magnetic poles in which N and S poles are alternately arranged in parallel are laminated. At this time, by arranging and laminating the magnetic poles so that the longitudinal directions thereof are orthogonal to each other, it is possible to form an attraction surface having a net-shaped magnetic pole on the surface. When forming an adsorption surface having a net-shaped magnetic pole on the surface of an object such as a wall surface, a board or a board, a net-shaped magnetic pole is formed when two sheet-shaped magnets are stacked one by one or before two sheet-shaped magnets are stacked. It is possible to adopt a method of laminating the materials.

Further, a sheet-like magnet may be laminated on a wall surface or a substrate with a magnetic material such as an ultra-thin iron foil interposed therebetween. Since it is desirable that the sheet-shaped magnet is in close contact with the substrate or the like, a magnetic material is provided as a means for eliminating irregularities on the contact surface with the magnet as much as possible so that efficient construction and assembly can be performed. When a magnetic material is interposed, the attraction force of the magnet can be increased by the yoke effect. When there are no irregularities on the surface of the wall surface or the substrate, it is not necessary to provide a magnetic body.

According to the method of the present invention, not only a net-shaped magnetic pole can be formed on the entire surface of a wall surface or a substrate, but also two magnet laminated portions can be formed only on a part of a wide surface. That is, the first sheet-like magnet is laminated only on a part of the wide surface,
The other part is to provide a height adjustment sheet or filler of the same thickness as the sheet magnet, and then partially form a net-shaped magnetic pole by laminating a second sheet magnet on the entire surface. Can be.

According to the method of the present invention, an attraction surface having a net-like magnetic pole can be formed from a ready-made multipolar magnetized sheet-like magnet in a place where there is no magnetizing equipment and no special equipment is required. An adsorption surface having a net-shaped magnetic pole can be formed on any flat surface or a curved surface such as a column, such as a board, a display board, and a game board.

According to the present invention, since the above-mentioned method is adopted, a multi-pole magnetized sheet can be easily formed in a place without magnetizing equipment without using any special equipment or cost for forming an adsorption surface. An attraction surface having a net-shaped magnetic pole can be formed from the magnet. As long as there is a ready-made multi-pole magnetized sheet magnet, a net-shaped adsorption surface can be formed anywhere, such as at a construction site, and is not limited to the entire surface such as a wall surface. It is also possible to form a net-shaped magnetic pole only on the surface.

Therefore, when one magnet is attracted and slid, a portion that can freely move in parallel at regular intervals or slide without stagnation, a portion that can not move at all, and a portion that can be made depending on the place or direction are placed on the same plane. It can be formed, depending on the application and usage, the attracting surface of the net-shaped magnetic pole and the attracting surface of multi-polar magnetized,
The operation of various magnets can be obtained by properly using an iron plate or the like, and the versatility for games and the like can be further expanded.
