Description
Technical field
The present invention relates to a kind of voice coil motors of miniature webcam, and in particular to a kind of component of voice coil motor.It is described micro-
Type camera can be assembled applied in the low profile electronics product such as mobile phone, tablet computer, smartwatch.
Background technology
In existing camera voice coil motor（VCM）In design, carrier is one of parts of most critical.In the carrier
Equipped with upper and lower first through hole, the eyeglass for assembling camera；The carrier periphery is arranged with coil, is corresponded in the yoke of motor
The coil is equipped with magnetite, constitutes when the coil is energized, and carrier can generate upper and lower directions displacement because of electromagnetic induction, to real
The zoom of existing camera, focusing；The top of the carrier or/and lower end surface there is also positioned shrapnel, for generating elasticity, ensure
In coil no power, carrier can restore to initial horizontality position.
As shown in Figure 1, 2, the carrier of existing design includes cylindrical pedestal 1 at present, and the periphery of pedestal 1 corresponds to coil and is equipped with
Coiling dispensing portion 3 and coiling loading end 4；Wherein, the bottom of carrier is surrounded by multiple plastic rubber surfaces 5.The load of the existing design
Body is contacted using carrier base plastic rubber surface 5 with magnetite in terms of controlling voice coil motor stroke, in this way the depth of parallelism to each plastic rubber surface 5
And the requirement of appearance is very high, and Machining Arc face 6 is needed, to increase the difficulty of mold processing, and in production process
Dispensing required precision it is very high；In addition, the structure design based on the existing carrier is carried when voice coil motor is by external impacts
The plastic rubber surface 5 of body is easy to deform because of the impact of external force, to reduce the reliability of voice coil motor.
In addition, in the design of existing voice coil motor, the lower surface of motor lower cover is equipped with groove, reserves the purpose of this groove
It is to meet the following group reload request that client carries out camera product.The design of groove whereby, Client Enterprise is to voice coil horse
It reaches and when holder is assembled, it is ensured that the assembly precision of the two, thus it is very high to this groove depth of parallelism and planarity requirements, in this way
Increase the difficulty of mold processing.
Therefore, above-mentioned the shortcomings of the prior art how is solved, is become as the project of the invention to be researched and solved.
Invention content
The object of the present invention is to provide a kind of components of voice coil motor.
In order to achieve the above objectives, the technical solution adopted by the present invention is：
A kind of component of voice coil motor, including a carrier and assembling are matched with the lower cover below the carrier；Wherein,
A first through hole is offered in the carrier along the vertical direction, the eyeglass for assembling camera；
The upper surface of the carrier is equipped with multiple first glue groove, and each first dispensing geosynclinal concave is set to the upper surface, by viscous
Close shrapnel on the one of connection positioning voice coil motor；
Wherein, at least three Stroke Control convex blocks are additionally provided on the upper surface of the carrier, each Stroke Control convex block is along institute
The circumferencial direction for stating first through hole is uniformly distributed one support terrace of composition, and the surface depth of parallelism of each Stroke Control convex block is consistent；
The stroke of carrier in above-below direction is limited by against the yoke of positioning voice coil motor；
One second through-hole is offered in the middle part of the lower cover, which is coaxially disposed with the first through hole；Wherein,
The upper surface of the lower cover is set there are four positioning column, multiple hot molten columns and a dust ring；Each positioning column is right respectively
Four angles of the upper surface are answered, the yoke is positioned for connecting；Each upward projection of the hot molten column, for welding positioning sound
The lower shrapnel of coil motor；The dust ring is arranged around second through-hole, with the second through-hole concentric；
The lower surface of the lower cover is set there are three bottom boss, and each bottom boss is arranged around second through-hole, and is in mutually 120
Angle arrangement is spent, the line for constituting three is a triangle.
Related content in above-mentioned technical proposal is explained as follows：
1. in said program, at least three Stroke Control convex blocks are uniformly distributed in circumferencial direction, the support day of a stabilization may make up
Face.Since the area of support terrace is larger, and it is not necessarily to Machining Arc face, therefore in the processing and production of mold compared with the prior art
It is easier to control, and is not likely to produce bad order；In addition it is not necessarily to dispensing herein in the production process of voice coil motor, therefore is not present
The bad problem of viscose glue.
2. in said program, each first glue groove is uniformly distributed in along the circumferencial direction of the first through hole on described
On end face.
3. in said program, multiple anti-rotation blocks, each anti-rotation block phase are also convexly equipped on the lateral wall of the carrier outwardly
Yoke positioning to voice coil motor, and each anti-rotation block is along the circumferential direction set to the surrounding of the carrier；It designs whereby,
Further reinforcement can be played to the structural strength of carrier, more preferably protect carrier when voice coil motor is by external impacts, make
It is hardly damaged.
4. in said program, wrapping post is convexly equipped with outwardly on the lateral wall of the carrier, the wrapping post is positioning voice coil
The line end of motor coil.
5. in said program, the dust ring is arranged around the second through-hole, play the role of the sealing carrier.
6. in said program, passing through the setting of three bottom boss, on the one hand, only need to ensure the surface of three bottom boss
The depth of parallelism and flatness, for the groove compared to previous entire lower surface, this case greatly reduce to the surface depth of parallelism and
The area of planarity requirements reduces the requirement to mold, reduces production cost；On the other hand, this by bottom boss
The design of protrusion, and " triangle " arrangement, Client Enterprise can also be convenient for voice coil motor and the other components of camera（Such as
Holder）Connection positioning, and the stability after positioning can be promoted.
7. in said program, the upper surface of the lower cover is additionally provided with anti-rotation convex block, which corresponds to the carrier and sets
It sets, is used for positioning carrier.
8. in said program, the lower surface of the lower cover is additionally provided with multiple PIN foot, for the other of electric property coupling camera
Component.
9. in said program, the lower surface of the lower cover is equipped with a bottom recesses, each bottom around second through-hole
Portion's boss is set in the bottom recesses.
The operation principle and advantage of the present invention is as follows：
Compared to existing technologies, of the invention：
One, it is uniformly distributed in circumferencial direction by least three Stroke Control convex blocks in carrier, may make up the support day of a stabilization
Face.Since the area of support terrace is larger, and it is not necessarily to Machining Arc face, therefore in the processing and production of mold compared with the prior art
It is easier to control, and is not likely to produce bad order；In addition it is not necessarily to dispensing herein in the production process of voice coil motor, therefore is not present
The bad problem of viscose glue.For the carrier of the present invention when voice coil motor is by external force collision, the area that carrier is impacted is larger, therefore
Deformation after shock is smaller, can effectively promote the reliability of voice coil motor, enables a customer to use with feeling more relieved；
Two, by the design of bottom boss in lower cover, the precision of client's assembling is neither influenced, it is good can also to effectively improve client's assembling
Rate, and the cost of mold processing can be reduced.
