Body 32, the outside of the carrier 32 is wound with coil 33, and the upper and lower side of the carrier 32 is respectively arranged with shell fragment 35 and lower bullet
Piece 34, is additionally provided with shell fragment lid 36 on the upper shell fragment 35, the outside of the coil 33 is provided with magnet assembly（Do not show in figure
Go out）, the magnet assembly（Not shown in figure）Outside be provided with yoke 37.
Embodiment 5
As shown in figure 5, a kind of inclination angle regulation method of voice coil motor, comprises the steps：
Step 1：Inclination maneuver seat and the pad 2 described in embodiment 2 described in embodiment 1 is provided；
Step 2：The pad 2 is adsorbed on the pedestal 11 of the Inclination maneuver seat, the spherical push rod 12 passes through it
Through hole；
Step 3：In one layer of viscose 4 of surface-coated of the pad 2；
Step 4：The spherical push rod 12 is adjusted to into suitable height, and voice coil motor is placed on into the spherical push rod
On 12 sphere, voice coil motor is set to contact with viscose 4；
Step 5：The angle of adjustment voice coil motor, makes the optical axis of voice coil motor perpendicular to pad 2；
Step 6：Viscose 4 between the pad 2 and voice coil motor is solidified.
Voice coil motor is all inevitably present the mistake on assembly error, or the design of each component during assembling
Difference, carrier 32 and non-perpendicular to base 31, when base 31 is placed in the horizontal plane, between the axis and vertical axes of carrier 32
There is a small inclination alpha, cause to there is also inclination alpha between the optical axis of voice coil motor and vertical axes.The technical program is by sound
Coil motor is placed on the sphere of the spherical push rod 12, and voice coil motor can make 360 ° of rotations on sphere, be given by active
One angle beta of voice coil motor is given, the optical axis of voice coil motor is made perpendicular to pad 2, the i.e. axis of carrier 32 and vertical overlapping of axles, its
Middle α=β；After having corrected the inclination alpha of voice coil motor, then the viscose 4 between voice coil motor and pad 2 is solidified, so as to complete
Into whole adjustment process.
Wherein, step 5 includes：
Step 5.1：One reflecting mirror 5, bottom of its reflecting surface towards voice coil motor are installed in the carrier 32 of voice coil motor；
Step 5.2：Collimator 6 is set in the bottom of spherical push rod 12, collimator 6 to the reflecting mirror 5 launches light, light
The reflected mirror 5 of line returns to collimator 6 after reflecting；
Step 5.3：The angle of adjustment voice coil motor, the incident ray and reflection light for making reflecting mirror 5 overlaps.
In an assembling process inevitably its carrier 32 can produce inclination alpha, and inclination alpha very little to voice coil motor, typically
Not over 30 points, i.e., less than half degree；Generally, if inclination alpha will be taken as waste product more than 20 points, the meaning of adjustment is lost
Justice, by taking the voice coil motor of a 8.5mm*8.5mm specification as an example, when the inclination alpha of its carrier 32 is 20 timesharing, after having corrected, its
The difference in height at the two ends of base 31 is 0.05mm, has no idea to distinguish with naked eyes and microscope, with existing technology for, only
The grade of collimator 6 can be adopted, and accurately equipment just can be detected.
As described above, after having corrected the inclination alpha of voice coil motor, its two ends of base 31 is with difference in height, i.e. base 31
There is an angle beta and pad 2 between, but difference in height is extremely small, because viscose 4 is uncured front with mobility, therefore,
In adjustment process, when 31 extruding pad 2 of base, uncured viscose 4 be enough to the gap filled up between base 31 and pad 2,
And make up the difference in height at the two ends of base 31.
Wherein, step 3 includes：
Step 3.1：In the through hole periphery coating heat-curable glue of the pad 2；
Step 3.2：In one layer of optic-solidified adhesive of heat-curable glue periphery coating.
Wherein, step 6 includes：
Step 6.1：Photocuring is carried out to the optic-solidified adhesive；
Step 6.2：Heat cure is carried out to the heat-curable glue.
Because after pad 2 and base 31 are bonded, ultraviolet light is difficult to enter between pad 2 and base 31, so first to pad
Periphery between piece 2 and base 31 is shaped using photocuring, then inside is finally fixed using heat cure.
Preferably, the viscose in step 3 is the dual-purpose glue of photo-thermal curing, then step 6 includes：
Step 6.1：Photocuring is carried out to the outer peripheral areas of the dual-purpose glue of the photo-thermal curing；
Step 6.2：Heat cure is carried out to the interior zone of the dual-purpose glue of the photo-thermal curing.
Preferably, the pad 2 is non-magnet material, in order to avoid to the magnetic fields inside voice coil motor.
Embodiment 6
A kind of assemble method of voice coil motor, comprises the steps：
Step 1：Each part of voice coil motor is fitted together, complete voice coil motor is formed；
Wherein, the voice coil motor is the voice coil motor described in embodiment 4, including base 31 and is arranged on the base 31
On carrier 32, the outside of the carrier 32 is wound with coil 33, and the upper and lower side of the carrier 32 is respectively arranged with shell fragment 35
With lower shell fragment 34, shell fragment lid 36 is additionally provided with the upper shell fragment 35, the outside of the coil 33 is provided with magnet assembly（In figure
It is not shown）, the magnet assembly（Not shown in figure）Outside be provided with yoke
Step 2：Using the inclination angle regulation method described in embodiment 5, the inclination angle of voice coil motor is adjusted.

As shown in fig. 6, a kind of voice coil motor, the bottom of the voice coil motor is pasted with a pad 2, the pad by viscose 4
Piece 2 has through hole, and the optical axis of the voice coil motor is perpendicular to the pad 2.
The concrete structure of the voice coil motor includes base 31 and the carrier 32 being arranged on the base 31, the carrier
32 outside is wound with coil 33, and the upper and lower side of the carrier 32 is respectively arranged with shell fragment 35 and lower shell fragment 34, the upper bullet
Shell fragment lid 36 is additionally provided with piece 35, the outside of the coil 33 is provided with magnet assembly（Not shown in figure）, the magnetic group
Part（Not shown in figure）Outside be provided with yoke.
Wherein, there is an angle beta between the voice coil motor and pad 2, i.e., have an angle between described base 31 and pad 2
β, the inclination alpha between the axis and vertical axes of carrier 32 is corrected by the angle beta, makes the optical axis and vertical axes weight of voice coil motor
Close, wherein β=α.
The viscose 4 includes being located at the heat-curable glue of the through hole periphery of the pad 2 and positioned at heat-curable glue periphery
Optic-solidified adhesive.
In the curing process, due to after pad 2 and base 31 are bonded, ultraviolet light be difficult to enter pad 2 and base 31 it
Between, so first being shaped using photocuring to the periphery between pad 2 and base 31, then inside is carried out most using heat cure
After fix.
