Description

A device for anti-magnetic pole reverse installation

technical field

The utility model belongs to the technical field of electronic devices, in particular to a device for preventing reverse magnetic pole installation.

Background technique

In electronic devices, magnetic materials are widely used. Magnet block is a relatively common magnetic material part. Regarding the assembly of magnets, in some cases, the product is assembled and then put into the magnetization system for magnetization. Its small size will not affect magnetization or use. However, after some products are assembled, the entire volume has become very large or irregular, and it cannot be magnetized. Therefore, it is necessary to magnetize it before assembly. After the magnet is magnetized, N poles and S poles will be generated. There are clear requirements for the direction of the magnetic poles, but the naked eye cannot distinguish which end is the N pole and which end is the S pole. Therefore, the accurate identification of the magnet polarity becomes a cumbersome process in the assembly of electronic devices, which restricts the assembly efficiency.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The concrete realization of the present utility model is described in detail below in conjunction with specific embodiment:

Please refer to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of anti-magnetic pole anti-installation device, comprises a base plate 10, and this base plate 10 is provided with the positioning groove 20, and the positioning groove 20 is opposite to the carrier 40 of the magnet 30 to be assembled. Matching means that the carrier 40 can just be placed into the positioning groove 20 , and its edge abuts against the edge of the positioning groove 20 . As shown in Figure 3, the carrier 40 is used to assemble the magnet, and its surface is provided with a hole 50 for installing the magnet, and the positioning groove 20 is provided with a groove 60 facing the hole 50 one by one, in each groove 60 is provided with a fixed magnet 70, the magnetic pole direction of the fixed magnet 70 is consistent with the magnetic pole direction of the magnet 30 to be assembled, that is, for any acupuncture point 50, the N pole of the fixed magnet 70 in the corresponding groove 60 is the same as that of the magnet to be assembled. The N poles of the magnet 30 have the same orientation, and the S poles of the fixed magnet 70 and the S pole of the magnet 30 to be assembled have the same orientation. Wherein, the height of the fixed magnet 70 is less than or equal to the depth of the groove 60 . Of course, both the substrate 10 and the carrier 40 are made of non-magnetic materials.

As shown in Figure 4, the device for anti-magnetic pole installation provided by this embodiment is provided with a groove 60 in the positioning groove 20, its position is directly opposite to the acupuncture point 50 on the carrier 40, and the polarity direction of the fixed magnet 70 in the groove 60 It is consistent with the polarity direction of the magnet 30 to be assembled, that is, the polarity direction of the fixed magnet 70 is preset as a standard direction. When the magnet is assembled on the carrier 40, take the magnet 30 to be assembled, and align its arbitrary pole with the acupuncture point 50. When it is close to the acupuncture point 50, if repulsion occurs, it means that the fixed magnet 70 at this place is compatible with the magnet to be assembled. The direction of the magnetic poles of 30 is opposite. For example, when the S pole is assembled downward, if the corresponding fixed magnet 70 has the S pole facing upward, the same-sex repulsion between the S pole and the S pole will occur, and then the fixed magnet can be easily judged. 70 is opposite to the magnetic pole direction of the magnet 30 to be assembled, and the assembly direction is wrong. At this time, the reverse assembly of the magnet will cause the opposite sex of the S pole and the N pole to attract each other, and then complete the correct assembly. The attraction or repulsion felt during assembly is more obvious, so this assembly method is easier to achieve correct assembly, and can significantly improve work efficiency. In addition, the height of the fixed magnet 70 is less than or equal to the depth of the groove 60, the fixed magnet 70 will not protrude out of the groove 60 and scratch the carrier 40, and can ensure that the carrier 40 is flat and easy to assemble the magnet.

In this embodiment, the height of the fixed magnet 70 should not be too small, because too small a height of the magnet will increase the distance from the magnet 30 to be assembled, causing the force between the magnet 30 to be assembled and the fixed magnet 70 to be insignificant. It is not easy to identify the right and wrong pole installation. Preferably, the height of the fixed magnet 70 is greater than 2/3 of the depth of the groove 60 and less than or equal to the depth of the groove 60 .

Further, for the convenience of placing and removing the carrier 40 , the depth of the positioning groove 20 of the substrate 10 is smaller than the thickness of the carrier 40 . Preferably, the depth of the positioning groove 20 is about two-thirds of the thickness of the bearing member 40 . If the depth is too large, it is difficult to remove the carrier 40, and if the depth is too small, the carrier 40 is easy to slide and difficult to locate.

In this embodiment, the size of the fixed magnet 70 is approximately equal to or similar to the size of the magnet 30 to be assembled. The size of the fixed magnet 70 in the direction parallel to the surface of the substrate is 1/2 to 2 times the size of the magnet 30 to be assembled in the direction parallel to the surface of the carrier. In the case of the same size, the interaction is more obvious, and if the difference is large, it will cause interference. In this embodiment, it is further preferred that the radial dimensions (dimensions parallel to the surface of the substrate and the carrier) of the two are equal. The fixed magnet 70 can be a cylindrical magnet, and the groove 60 can also be set in a cylindrical shape slightly larger than the size of the fixed magnet 70 .

The anti-magnetic pole anti-installation device has a simple structure and is convenient to use, and the magnetic pole judgment is fast and accurate, and it is easy to correct when an assembly error occurs, effectively improving work efficiency, and is suitable for the magnetic material assembly process in the mass production of electronic devices.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
