Abstract
The invention discloses a magnetic assembly for a Hall element. The magnetic assembly comprises a nylon part and a permanent magnet embedded into the nylon part, wherein corner positioning blocks are arranged at the corners of the permanent magnet, and the nylon part is provided with matched grooves corresponding to the corner positioning blocks of the permanent magnet; and a metal insert for assembling the magnetic assembly onto other rotating component is further embedded into the nylon part. The permanent magnet and the metal insert are injected into a nylon plastic package, and positioning blocks are arranged at the corners of the permanent magnet, so that the permanent magnet can be accurately positioned, the technical problem that epoxy resin is needed for sticking due to infirm mechanical structure when the permanent magnet is assembled in the past is solved, meanwhile, an epoxy resin curing process is saved, the material cost is reduced, the manpower and equipment costs are reduced, and the production efficiency and the product yield are improved.
Description
Technical field
The present invention relates to technical field of manufacturing semiconductors, the magnet assembly of particularly a kind of supporting Hall element use.
Background technology
Hall element is a kind of Magnetic Sensor based on Hall effect, is used for detecting magnetic field and change thereof, can use in the various occasion relevant with magnetic field.Therefore, need externally-applied magnetic field during Hall element work, the generation in magnetic field adopts the permanent magnet of rare earth material usually; Under normal circumstances, the magnet assembly adopting Hall element secure fit to be made up of permanent magnet adopts the mode of rotation or movement to carry out work.
Magnet assembly, in rotation or moving process, needs to move together with miscellaneous part or by miscellaneous part together brought into motion.As shown in Figure 1, permanent magnet is assemblied in nylon the structure of traditional magnetic assembly, and be then coated with unimolecule epoxy resin 5 in permanent magnet surfaces, then cover cover plate 4, entirety puts into curing oven, makes it into as a whole.What traditional technique adopted is 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 oven equipment needed is with to take manual time more, not only assembling technology procedure more complicated is cumbersome, and increases production cost; In addition, epoxy resin overflows and unacceptable product also can be caused again to produce.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of, magnet assembly that production efficiency high, with low cost simple for the making in Hall element, high to improve its product percent of pass.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
For the magnet assembly in Hall element, the permanent magnet comprising nylon part and be inlaid in nylon part, the corner of described permanent magnet is provided with corner locating piece, and the position of nylon part corresponding permanent magnet corner locating piece is provided with groove equipped mutually; The metal insert for being assembled to by magnet assembly on other rotatable parts is also embedded with in described nylon part.
Above-mentioned for the magnet assembly in Hall element, offer strip relief hole in the middle part of described permanent magnet.
Above-mentioned for the magnet assembly in Hall element, described nylon part forms nylon bag plastomer by the disposable injection moulding of nylon material.
Owing to have employed above technical scheme, the invention technological progress is as follows.
Permanent magnet and metal insert are injection-moulded in nylon bag plastomer by the present invention, and locating piece is set by the corner at permanent magnet, permanent magnet is accurately located, solve physical construction when originally assembling permanent magnet and loosely need adhering with epoxy resin technical barrier, eliminate epoxy resin cure technique simultaneously, save material cost, reduced artificial and equipment cost, improve production efficiency and product percent of pass.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional magnetic assembly;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the right view of permanent magnet of the present invention.
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.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
A kind of for the magnet assembly in 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 nylon part corresponding permanent magnet corner locating piece 6 is provided with groove equipped mutually, to ensure that magnet assembly permanent magnet in manufacturing process can accurately be located.
In the present embodiment, nylon part forms nylon bag plastomer 2 by the disposable injection moulding of nylon material.Offer strip relief hole 7 in the middle part of permanent magnet 3, prevent permanent magnet in nylon material injection moulding process to be squeezed power and chipping.Entire body of the present invention adopts injection molding manner, parts is installed and firmly can have good barrier propterty again, improve production efficiency, saved production cost, reduce product disqualification rate.
Claims (3)
1. for the magnet assembly in Hall element, comprise nylon part and be inlaid in the permanent magnet (3) in nylon part, it is characterized in that: the corner of described permanent magnet (3) is provided with corner locating piece (6), the position of corresponding permanent magnet corner locating piece (6) of nylon part is provided with groove equipped mutually; The metal insert (1) for being assembled to by magnet assembly on other rotatable parts is also embedded with in described nylon part.
