Description
Technical field
The present invention relates to a kind of camera installation, particularly relate to stamped metal part and moulding connecting shaping structure in a kind of voice coil motor.
Background technology
As shown in Figure 1 and Figure 2, in the voice coil motor commonly used, lower cover 2 ' and terminal 3 ' process respectively, then by both assemblings together, concrete assemble method is:
1, at upper surface point viscose glue or the UV glue of lower cover 2 ';
2, terminal 3 ' is placed on lower cover 2 ' surface, the projection 22 ' on lower cover 2 ' is coordinated with the locating hole 31 ' in terminal 3 ' and installs;
3, following, shell fragment 1 ' is arranged on lower cover 2 ' surface, then sends into baking box or UV light irradiation makes adhesive curing, namely reach and terminal 3 ' is pre-fixed with on lower cover 2 '.Further, shell fragment 1 ' needs to weld with terminal 3 ', thus realizes conducting.Afterwards assembling parts remaining for voice coil motor is completed that (this has technique for habit, do not repeating at this), finally, load in shell 4 ' (as shown in Figure 3), because lower cover 2 ' side jagged 21 ' is for accommodating terminal 3 ', so, after loading shell, still jagged existence bottom product, at this moment, need at breach 21 ' some glue, then send into oven for solidifying, thus this breach is filled and led up.Because voice coil motor is very high to required precision, in above-mentioned production process, when terminal 3 ' pre-fixes with lower cover 2 ', after some glue, need feeding baking box to carry out baking to fix, because colloid has mobility, be transported in baking box from a glue station, transport process likely can produce shake, then terminal can offset, bad product will be produced, if just minimum skew, and after not detecting defective products fit on shell fragment, because shell fragment needs to drive optical lens to realize focusing, it can produce and move forward and backward, so, because the installation of terminal is not in place, shell fragment likely can be out of shape, even there is the problems such as focus operation has some setbacks.Thus affect the packaging efficiency of voice coil motor, stability and yields.Separately, fill and lead up in the operation of breach after product loads onto shell, need the upper a large amount of glue of point, glue likely can flow down along product sidewall, just needs artificial removal; Also there will be, a large amount of glue flows into voice coil motor along the inwall of shell, can cause interference to focus operation simultaneously; Certainly also there will be, after once putting glue baking-curing, also do not fill and lead up breach completely, need secondary to mend the situation of glue, cause complex process like this, production efficiency is low.
Summary of the invention
Stamped metal part and moulding connecting shaping structure in the voice coil motor that the object of the present invention is to provide a kind of product yielding and not easy to assembly.
For achieving the above object, technical solution of the present invention is:
The present invention is stamped metal part and moulding connecting shaping structure in a kind of voice coil motor, and it comprises lower cover, two terminals; Described lower cover offers groove and jack respectively in adjacent two bights, is arranged with locating dowel at the outer of groove; Described terminal is made up of connecting portion and insertion section, connecting portion is connected with insertion section is vertical, connecting portion offers locating hole, insertion section on two terminals is set in two jacks respectively, and the locating hole on terminal connection part is socketed in lower cover locating dowel and connecting portion covers on the groove notch of lower cover;
Cover under described and be provided with two locating dowels; Described terminal connection part offers locating hole, and two locating holes on terminal connection part are socketed in down in two locating dowels that cover respectively.
Described lower cover and two terminals are integrated component.
After adopting such scheme, the present invention due to by lower cover and terminal one-body molded, eliminate the technique pre-fixing an adhesive curing of lower cover in original technique and terminal, also eliminate after loading onto shell and put the technique that breach filled and led up by glue, greatly reduce the risk that product produces fraction defective, simultaneously, under cover and offer groove, during assembling, locating hole on terminal connection part is socketed in lower cover locating dowel and connecting portion covers on the groove notch of lower cover, two bights of lower shell fragment are welded on the end face of the terminal connection part be installed on lower cover bight respectively, because terminal connection part covers on the groove notch of lower cover, the heat produced when lower shell fragment and terminal soldering sheds by the groove of lower cover, lower cover is not yielding.
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.

Detailed description of the invention
As shown in Figure 4, Figure 5, the present invention is stamped metal part and moulding connecting shaping structure in a kind of voice coil motor, and it comprises lower cover 1 and two terminals 2.
Described lower cover 1 is rectangular, offers a groove 11 and a jack (not shown) respectively in adjacent two bights, is arranged with two locating dowels 13 at the outer of groove 11.
Described terminal 2 is made up of connecting portion 21 and insertion section 22.Connecting portion 21 is connected with insertion section 22 is vertical, connecting portion 21 offers two locating holes 211, insertion section 22 on two terminals 2 is set in two jacks of lower cover 1 respectively, and the locating hole 211 on terminal 2 connecting portion 21 is socketed in lower cover 1 locating dowel 13 and connecting portion 21 covers on groove 11 notch of lower cover 1.
Described lower cover 1 and two terminals 2 adopt insert injection molding method to be processed into integral member.
In voice coil motor production process, two described terminals 2 need be electrically connected with lower shell fragment 3, the processing method of the present embodiment is as follows: the profile of described lower shell fragment 3 is corresponding to the profile of lower cover 1, also be rectangle, lower shell fragment 3 snaps onto on lower cover 1, the end face of terminal 2 connecting portion 21 of two bights difference welded and installed on lower cover 1 bight of lower shell fragment 3.
As shown in Figure 6, after having assembled, finally, the present invention is loaded in shell 4.
As shown in Figure 4, Figure 5, the present invention is the processing technology of stamped metal part and moulding connecting shaping structure in a kind of voice coil motor, comprises the following steps:
1, adopt insert molding technology, by lower cover 1 and two terminals 2 one-body molded, that is, terminal 2 is placed in molding mold cavity as inserts, then injection mo(u)lding lower cover 1, like this, terminal 2 is just one-body molded with lower cover 1;
2, lower cover 1 glue, is bonded together lower shell fragment 3 with terminal 2;
3, lower shell fragment 3 adds tin with terminal 2 connecting portion 21;
4, lower shell fragment 3 welds with the connecting portion 21 of terminal 2.Like this, under welding when shell fragment 3 and terminal 2, because plumb joint temperature is very high, the temperature on its terminal 2 surface just can be dispelled the heat by groove 11, ensures that lower plastic cover 1 is unlikely to be out of shape by after high temperature.
Emphasis of the present invention is just: under cover the groove offered for dispelling the heat.
The above, be only present pre-ferred embodiments, the shape of groove can have multiple, therefore can not limit scope of the invention process with this, namely the equivalence done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
