Abstract
The invention provides an assembling process for a voice coil motor assembly coil and an elastic sheet. The voice coil motor assembly coil and an elastic sheet comprises a coil bracket, a coil which winds the coil bracket, and two opposite lower elastic sheets which fit each other on the upper part of the coil bracket. The edge of the upper flange of the coil bracket is provided with at least two opposite projected pins in the radial direction. The starting end and the tail end of the coil respectively wind the two opposite projected pins. The two lower elastic sheets are respectively welded with the coils on the two projected pins. When the coil winds the coil bracket, the coil is wound on the projected pins for positioning and then the coil is wound along the coil bracket, thereby preventing starting-end wire offset, realizing no requirement for manual secondary wire pulling-out and effectively reducing manufacture cost. Furthermore the lower elastic sheets realize automatic equipment operation for fitting on the coil bracket, thereby realizing flat soldering with the coil which winds on the projected pins, obtaining higher binding firmness between the lower elastic sheets, preventing breakage, ensuring high product quality of the voice coil motor assembly, realizing welding and assembling of automatic equipment and greatly improving production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 2 to 5, the present invention has disclosed the package assembly of a kind of voice coil motor assembly coil and shell fragment, this voice coil motor assembly comprises that the pad 3, of a shell 1, a fixed magnets 2 is engaged in upper shell fragment 4, a coil brace 5 of pad 3, is wrapped in coil 6 on coil brace 5, is fixed on upper cover 9 after being engaged in 7, twice shell fragments of twice shell fragments relative on coil brace 57 and terminal 8 welding. Upper shell fragment 4 outer rings, magnet 2 and pad 3 and twice shell fragment 7 outer rings form fixation kit; Form mobile component and be wound with the coil brace 5 of coil 6 and twice shell fragment 7 inner rings and upper shell fragment 4 inner rings; Shell 1 forms chamber with accommodating listed each parts with upper cover 9.
Key of the present invention is: this coil brace 5 is a sleeve, can be square or circular, its top and bottom form respectively convex edge 51, lower convex edge 52, supporter 53 for being wound around for coil 6 between 51Yu Xia convex edge, upper convex edge 52, wherein go up and in 51 outer rims of convex edge, be radially provided with two at least relative protruding pin 511, the initiating terminal 61 of coil 6 is wrapped in respectively on two relative protruding pin 511 with ending end 62, twice shell fragments 7 respectively with two protruding pin 511 on coil welding.
In this embodiment, be example taking coil brace 5 as square sleeve, on its four limits, be equipped with a protruding pin 511, and be even configuration, to reach balanced action.
Wherein a protruding pin 511 forms a short slot 512 along its root, the bottom land of this short slot 512 is concordant with supporter 53, this protruding pin 511 with short slot 512 just forms the initiating terminal that coil 6 winds the line, in the time implementing coiling, the end of a thread of coil 6 initiating terminals 61 is located after being first wound around a circle or multi-turn on this protruding pin 511, avoid the skew of initiating terminal 61 the end of a thread, be wound around along supporter 53 again, because of the setting of short slot 512, can ensure that coil 6 carries out can be close to supporter 53 in the time that supporter 53 is wound around, ensure the compactibility that coil 6 is wound around, after pitch of the laps 6 has been wound around, its ending end 62 can be wrapped on another protruding pin 511 relative with the protruding pin 511 of initiating terminal, and the winding of carrying out again a circle or multi-turn simultaneously on this protruding pin 511 realizes fixing.
The packaging technology of voice coil motor assembly coil of the present invention and shell fragment, its concrete steps are:
Step 1, coil 6 is wrapped on coil brace 5, the initiating terminal 61 of coil 6 is wrapped in respectively on the two protruding pin 511 that coil brace 5 is relative with ending end 62;
Step 2, the coil brace 5 that is wound with coil 6 is packed in smelting tool, its upper surface carries out partial points glue, so that fixing lower shell fragment 7;
Step 3, adopt automation equipment to be contained in the upper surface of coil brace 5 on two relative lower shell fragments 7, twice shell fragment 7 is laminated on respectively on the two protruding pin 511 that coil brace 5 is relative, toasts and pre-fixes;
Step 4, take out and be placed in welding equipment completing the coil brace 5 that pre-fixes lower shell fragment 7, in twice shell fragments 7 and the position that two protruding pin 511 contact, descend the contact position of shell fragment 7 and coil 6 to carry out a tin cream;
Step 5, scolding tin or laser weld reinforcing on tin cream, just completed the assembling of voice coil motor assembly coil and shell fragment.
Certainly, above-mentioned steps 2, without setting, just pre-fixes without toasting in step 3, directly the coil brace 5 that laminates lower shell fragment 7 is carried out to a tin cream and also can.
In described step 5, carry out laser weld and can further realize and do not occur quick-fried tin problem, when welding by tin cream point the position in needs welding, with area and the position of CCD camera scanning tin cream, scanned rear employing segmented temperature and welded.
The control of described segmented temperature is to be set to two-part temperature: first paragraph temperature is to be set to 0-170 DEG C, and this section of temperature adopts the continuous light temperature that slowly raises, and object first slowly gasifies rosin; Second segment temperature is to be set to more than 240 DEG C, and this section of temperature adopts pulsed light moment high temperature to reach the temperature of tin sweat(ing) liquefaction welding, thereby completes the action of whole welding.
In sum, the package assembly of voice coil motor assembly coil of the present invention and shell fragment, by being provided with two relative protruding pin 511 on the coil brace 5 being wound around at coil 6, make coil 6 in the time being wound on coil brace 5, can first be wrapped on protruding pin 511 and carry out again along the winding of coil brace supporter 53 behind location, avoid the skew of initiating terminal 61 the end of a thread, without the operation of carrying out as artificial secondary is taken out the end of a thread in prior art, also be wrapped on another protruding pin 511 with the end 62 that finishes up season, make the assembly processing of coil and shell fragment simple, effectively reduce cost of manufacture; The lower shell fragment 7 of order is realized automation equipment cooperation on coil brace 5, develop soldering with the coil being wrapped on protruding pin 511, and realize the welding assembly of automation equipment, greatly enhance productivity, because the contact area of the coil on protruding pin 511 and lower shell fragment 7 is large, therefore the joint between the two is more firm, there will not be the problem of disconnection, ensures voice coil motor assembly product quality.
In addition, adopt the laser segmented formula welding of sound, avoid occurring quick-fried tin problem, further promote voice coil motor assembly product quality.
The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
