Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
See also Fig. 1, the assembled fixture 10 that first embodiment of the invention provides comprises the plummer 104 of magnetic conductive part 106 and this magnetic conductive part 106 of carrying.
Plummer 104 has a surface 1041, is provided with four location structures 105 on surface 1041, and location structure 105 is symmetrically distributed about the center of plummer 104, and it is used for fixing voice coil motor to be assembled.
Be appreciated that location structure 105 can also be two, preferably, the center of these two relative plummers 104 of location structure is symmetrically distributed, though this structure has only been fixed two in the summit, four right angles of voice coil motor,, just can not influence assembling effect as long as fixed.
Voice coil motor to be assembled is a fixed mount 20 at this moment, and fixed mount 20 is support bodys that are cuboid.This fixed mount 20 has four sidewalls perpendicular to carrier-table surface 1041, and these four sidewalls surround a containing cavity 201, and in the assembling process, magnetic conductive part 106 is positioned at this containing cavity 201.Offer one on each sidewall and put magnetic portion, therefore having four puts magnetic portion 202,204,206,208, and each is put magnetic portion and is used to place magnetic element, for example magnet.
Magnetic conductive part 106 can be made by the magnetic stainless steel material, has low magnetic resistance, is cylindric.The effect of magnetic conductive part 106 is the repulsion of offsetting in assembling process between magnetic element, and it is positioned at the zone that four location structures 105 are limit, and it can be fixed in carrier-table surface 1041 in modes such as welding, splicing.
Preferably, can establish the fixed part of the size match of a size and magnetic conductive part 106 in carrier-table surface 1041, for example groove etc. so that magnetic conductive part 106 is arranged in this fixed part, is convenient to substitute this magnetic conductive part 106.Preferably, this fixed position is in the center in the zone that four location structures 105 are limit, so that magnetic conductive part 106 can be positioned at the center of containing cavity 201.
If there is not magnetic conductive part 106, after having assembled a magnetic element, for example, after magnetic element 21 inserted magnetic portion 202, magnetic element 22 is sticked when putting magnetic portion 204 or put magnetic portion 206 or put magnetic portion 208, because the repulsion between magnetic element 21 and the magnetic element 22 is difficult to be assembled into correct position with magnetic element 22, will cause the 3rd magnetic element, the 4th magnetic element assembling difficulty like this.Magnetic conductive part 106 can be subdued the repulsion between the relative or adjacent magnetic element, makes magnetic element be easy to assembling.
During assembling, can earlier magnetic conductive part 106 be fixed in plummer 104, be that the center utilizes location structure 105 to place fixed mount 20 with this magnetic conductive part 106 again, again magnetic element 21 is attached at the magnetic portion 202 of putting of fixed mount 20, again all the other magnetic elements are inserted magnetic portion 204,206,208; Perhaps, also can earlier fixed mount 20 be placed plummer 104, again magnetic conductive part 106 be placed the center of containing cavity 201, magnetic element is installed again.
See also Fig. 2, the assembled fixture 10 that the assembled fixture 11 that second embodiment of the invention provides and first embodiment provide is basic identical, difference is: magnetic conductive part 107 is cuboids, also can be a square, its size be to be advisable in the zone that can be positioned over four location structures 105 and limited.
See also Fig. 3, the assembled fixture 10 that the assembled fixture 30 that third embodiment of the invention provides and first embodiment provide is basic identical, and difference is: assembled fixture 30 has a pedestal 102, and pedestal 102 has a surface 1021.Plummer 104 is positioned at base-plates surface 1021.
Four sliding parts 31,32,33,34 that the surface 1021 of pedestal 102 also is provided with four sections identical slide rails 301 and can moves along this slide rail, wherein, four sections slide rails 301 all point to plummer 104.
Because four sliding parts are basic identical, be that example describes therefore with sliding part 31.
Sliding part 31 comprises slide unit 302 and thimble seat 303, and wherein, slide unit 302 can slide along slide rail 301, and slide unit 302 has a surface 3021, and thimble seat 303 is located at slide unit surface 3021.
During assembling, earlier magnet 21 is placed magnetic portion 202, slide unit 302 is shifted to the magnetic portion 202 of putting along slide rail 301, just props up magnet 21 up to the top of thimble 304, and at this moment, slide unit 302 is no longer mobile.
At magnet 21 with put the joint millet cake glue of magnetic portion 202, for example use ultraviolet glue then.After adhesive curing, slide unit 302 is removed.
The magnet of four direction is installed and can be carried out simultaneously.
Preferably, the junction surface of thimble 304 and thimble seat 303 is provided with spring assembly 3041, and spring assembly 3041 is sheathed on the periphery of part thimble in a tubular form, and links to each other with thimble seat 303.
Pressure when spring assembly 3041 can cushion thimble 304 and touches mutually with magnet 21 makes thimble 304 to slow down the pressure of colliding along its axial shrinkage, in order to avoid fixed mount 20 is damaged.Certainly, the degree of this contraction is unlikely to make thimble 304 and its magnet that will prop up to be separated.
See also Fig. 4, the assembled fixture 30 that assembled fixture 40 that fourth embodiment of the invention provides and the 3rd embodiment provide is basic identical, difference is: the sliding part 41 of assembled fixture 40 also comprises second thimble 406 that be arranged in parallel with first thimble 404, two thimbles are located at slide unit 402, all point to and samely put magnetic portion, and thimble 404,406 is not all established spring assembly.
Other three sliding parts are identical with the structure of sliding part 41.
See also Fig. 5, the assembled fixture 30 that assembled fixture 50 that fifth embodiment of the invention provides and the 3rd embodiment provide is basic identical, and difference is: each sliding part 51 of assembled fixture 50 all has first thimble 504 and second thimble 505 that is parallel to each other; Also comprise four stopper sections 61 that structure is identical in addition, and stopper section 61 corresponding sliding parts 51.
Draw-in groove 611 and draw-in groove 612 are divided into the both sides of slide rail 301, and stop part 613 is a rod shaped structure, have first end 6131 and second end 6132.
It is free end that first end 6131 is fixed in draw-in groove 611, the second ends 6132 rotationally, can be placed in the draw-in groove 612.
During assembling, first thimble 504 and second thimble 505 are propped up after the magnet 21, second end 6132 of stop part 613 is placed in the draw-in groove 612, to stop slide unit 302 to moving away from the direction of putting magnetic portion.
Finish when a glue, determine magnetic element 21 be fixed in put magnetic portion after, free end 6132 is lifted, make sliding part 51 along slide rail 301 away from plummer.
Four magnetic elements can be assembled simultaneously.
In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
