Embodiment
To combine accompanying drawing below, the present invention will be done further explain.
See also Fig. 1 and Fig. 2, the assembly fixture for voice coil motor 400 that first embodiment of the invention provides comprises base 500 and lid 600.
Body 50 have a surface 501 with one with surperficial 501 relative another surperficial 505.Three support columns 502 are positioned at surface 501, and the line of three support column posts 502 roughly is an equilateral triangle, and the center of this equilateral triangle overlaps with the center of body 50.
Each foot 504 has an end face 5041, and a pair of foot 504 wherein also has a location hole 5042 respectively, and this location hole 5042 is positioned at the end face 5041 of this a pair of foot 504.Foot 504 is perpendicular to body surface 501.
Two pairs of location structures 503 are perpendicular to base body surface 501, and are positioned at the intersection of body surface 501 and foot 504, and every pair of location structure is the diagonal angle and distributes.Location structure 503 is a triangular prism structure with right angle groove; Triangular prism is drilled to right angle groove towards the drift angle at body 50 centers along the direction perpendicular to body surface 501; This right angle groove matches with waiting the angle of assembling voice coil motor, thereby reaches the effect of stationary tone coil motor.In actual production, this place, right angle is not strict right angle, but a rounding.
Body 60 have a surface 601 and with 601 relative another surface, surface 605.Lid pin 604 has an end face 6041, and wherein a pair of lid pin has an angle 6042 respectively, and this angle 6042 is positioned at the end face 6041 of this a pair of angle 6042.Lid pin 604 is perpendicular to body surface 601.
Two pairs of location structures 603 are perpendicular to body surface 601, and are positioned at the intersection of body surface 601 and lid pin 604.The structure of location structure 603 is identical with the location structure 503 of base 500.
Two magnet grooves 606 are positioned at surface 605.Magnet groove 606 is used to place magnet, the consistent size of magnet size of being placed and magnet groove, and place two blocks of magnet of base 500 and place the placement of two blocks of magnet of lid 600 should make that lower magnet attracts each other.
Because all being gummeds, each spare part of voice coil motor to be assembled forms; Its stress that can bear is limited; Therefore present embodiment is respectively equipped with two magnet grooves in base 500 and lid 600, and each magnet groove is equipped with a magnet, after lid 600 and base 500 assemble completion; Just can magnet be positioned in the magnet groove; Utilize the attraction between two magnet of two magnet and base 500 of lid 600, evenly apply pressure to lid plate and the lower cover of waiting to assemble voice coil motor, avoid waiting to assemble voice coil motor and in assembling process, produce the phenomenon that part is impaired or get loose because of the maximum stress of going beyond gummed.
Because be provided with the cause of lower magnet; Present embodiment three support columns 502 that provide on the base 500 be cooperate wait to assemble on the voice coil motor upper cover plate can support place and install; Its installing purpose is that the voice coil motor after assembling is accomplished is conveniently taken off, and can not make in its positioner that sinks into base because of the magnetic pull traction.
The setting that is appreciated that angle and location hole can be exchanged, that is, base 500 has angle and lid 600 has location hole.The quantity of angle and location hole and shape also are not limited to can design according to actual needs shown in the embodiment.
The magnet groove that is appreciated that base 500 and lid 600 can be one, three or other numbers, and its shape size is design according to actual needs all.
In addition, the quantity of support column also can or be established two, four according to the actual conditions omission.
Please referring to Fig. 3; The base 500 that the base 700 that second embodiment of the invention provides and first embodiment provide is roughly the same; Its difference is: foot 704 has a side surface 7041 towards the body center, and this side surface 7041 is provided with location structure 703.
Accordingly, the setting of the location structure of the lid 800 that provides of present embodiment is provided with consistent with the location structure of base 700.
Below, be the number of assembling steps that example is explained voice coil motor particularly with the first embodiment of the invention.
Please, utilize the step of assembly fixture for voice coil motor 400 assembling magnetic elements to comprise in the lump referring to Fig. 4 and Fig. 5:
At first, with waiting to assemble on the support column 502 that voice coil motor 10 places base 500;
Secondly, angle 6042 is stretched into location hole 5042 and can accommodate the receiving space of waiting to assemble voice coil motor so that lid 600 engages formation one with base 500.Simultaneously, lid 600, base 500, lid pin 604 and foot 504 limit four magnetic element assembly sections 121 jointly;
Once more, four blocks of magnet 11 are put into the magnet groove of base 500 and lid 600 respectively;
Once more, with magnetic element 12 through magnetic element assembly section 121 with wait to assemble voice coil motor 10 gummeds;
At last, lid 600 is taken off, the voice coil motor that takes out the assembling completion gets final product.
In addition, for the person of ordinary skill of the art, can make other various corresponding variations according to technical scheme of the present invention and technical conceive, and all these variations should be included in all within the present invention's scope required for protection.
