Abstract
The utility model discloses a magnetic component for among hall element, including nylon spare and inlay the permanent magnet of dress in nylon spare, the corner of permanent magnet is provided with the corner locating piece, and the position that nylon spare corresponds permanent magnet corner locating piece is provided with the recess that matches and adorn, still inlay in the nylon spare to be equipped with and be used for assembling the metal insert on other rotatable parts with magnetic component. The utility model discloses mould plastics permanent magnet and metal insert in the nylon bag plastomer to setting up the locating piece through the corner at the permanent magnet, making the permanent magnet can the accurate positioning, mechanical structure firmly need epoxy bonding technological problem when having solved original assembly permanent magnet, has saved epoxy solidification technology simultaneously, has practiced thrift material cost, has reduced manual work and equipment cost, has improved production efficiency and product percent of pass.
Description
Technical field
The utility model relates to technical field of manufacturing semiconductors, the magnet assembly that particularly a kind of supporting Hall element uses.
Background technology
Hall element is a kind of Magnetic Sensor based on Hall effect, is used for detecting magnetic field and variation thereof, can in the various occasions relevant with magnetic field, use. Therefore, when Hall element work, need to have externally-applied magnetic field, the generation in magnetic field adopts the permanent magnet of rare earth material conventionally; Under normal circumstances, adopt the magnet assembly that Hall element secure fit is made up of permanent magnet to adopt the mode of rotating or move to carry out work.
Magnet assembly, in rotation or moving process, need to move or drive together motion by miscellaneous part together with miscellaneous part. As shown in Figure 1, permanent magnet is assemblied in nylon the structure of traditional magnetic assembly, is then coated with unimolecule epoxy resin 5 in permanent magnet surfaces, then covers cover plate 4, and entirety is put into curing oven, makes it into as a whole. Traditional process using be mechanical assembly structure, this kind of version is insecure, need to fill with unimolecule adhering with epoxy resin, but epoxy resin cure production efficiency is low, the baking oven equipment needing is with to take the artificial time more, not only assembling technology procedure more complicated is cumbersome, and has strengthened production cost; In addition, epoxy resin overflows and also can cause defective work to produce.
Summary of the invention
The utility model technical issues that need to address are to provide the magnet assembly that a kind of making for Hall element is simple, production efficiency is high, with low cost, high to improve its product percent of pass.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
For the magnet assembly of Hall element, comprise nylon part and be inlaid in the permanent magnet in nylon part, the corner of described permanent magnet is provided with corner locating piece, and the position of the corresponding permanent magnet of nylon part corner locating piece is provided with mutually equipped groove; In described nylon part, be also embedded with for magnet assembly being assembled to the metal insert on other rotatable parts.
The above-mentioned magnet assembly for Hall element, described permanent magnet middle part offers strip relief hole.
The above-mentioned magnet assembly for Hall element, described nylon part forms nylon bag plastomer by the disposable injection moulding of nylon material.
Owing to having adopted above technical scheme, the obtained technological progress of the utility model is as follows.
The utility model is injection-moulded in permanent magnet and metal insert in nylon bag plastomer, and by the corner at permanent magnet, locating piece is set, permanent magnet can accurately be located, the not firm adhering with epoxy resin technical barrier that needs of frame for movement while having solved original assembling permanent magnet, saved Epoxy Resin metallization processes simultaneously, save material cost, reduced artificial and equipment cost, improved production efficiency and product percent of pass.
Brief description of the drawings
Fig. 1 is the structural representation of traditional magnetic assembly;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the right view of permanent magnet described in the utility model.
Wherein: 1. metal insert, 2. nylon bag plastomer, 3. permanent magnet, 4. cover plate, 5. epoxy resin, 6. corner locating piece, 7. pressure relief vent.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of magnet assembly for Hall element, its structure as shown in Figure 2, comprise nylon part, metal insert 1 and permanent magnet 3, one end of metal insert 1 and whole permanent magnet 3 are inlaid in nylon part, and metal insert is for being assembled to other rotatable parts by magnet assembly.
The structure of permanent magnet 3 as shown in Figures 2 and 3, matrix is rectangular structure, the edge of permanent magnet is provided with corner locating piece 6, and the position of the corresponding permanent magnet of nylon part corner locating piece 6 is provided with mutually equipped groove, to ensure that magnet assembly permanent magnet in manufacturing process can accurately locate.
In the present embodiment, nylon part forms nylon bag plastomer 2 by the disposable injection moulding of nylon material. Permanent magnet 3 middle parts offer strip relief hole 7, prevent in nylon material injection moulding process be squeezed power and chipping of permanent magnet. The utility model entire body adopts injection moulding mode, parts is installed and firmly can be had again good barrier propterty, has improved production efficiency, has saved production cost, has reduced product disqualification rate.
