Abstract
The utility model discloses a laser melting welding cooperation structure of voice coil motor, including base, terminal and back reed, the terminal setting in base and back and be connected through laser melting welding and back reed between the reed, back reed on be equipped with the rectangle through -hole, the through -hole be located the edge of terminal cooperation position, through -hole length and terminal length unanimity or be greater than the terminal width. Compared with the prior art, the beneficial effects of the utility model are that: can ensure the better product butt fusion of carrying on with this structure to and realize that visual inspection welds the effect, on the one hand can be better reach the welded effect, another aspect can confirm through the inspection that the welding effect prevents that rosin joint and welding defective products from flowing, stabilizes production efficiency, guarantees the quality of production product.
Description
Technical field
This utility model relates to electromagnetic technology field voice coil motor product, particularly relates to the laser fusion welding fit structure of a kind of voice coil motor.
Background technology
After in the voice coil motor (VCM) adopted in domestic and international minisize pick-up head at present and other micromachine, the welding manner of reed and terminal all adopts manual welding tin welding mode or adopts the connected mode of conductive silver glue, adopt this kind of conduction mode, it is necessarily required to bigger bonding area, plug-in type must be adopted to weld simultaneously, or two vertical cross-section welding, technique VCM being required day by day to microminiaturization, this kind of welding procedure takies larger area and solder joint is very big, take internal structural space, adopting manual work, welding difficulty and welding quality can not be guaranteed simultaneously.
Now with a kind of novel laser fusion welding technique, solder joint is little and can realize automatization's batch jobs, but the inspection of this method is cumbersome, it is impossible to find rosin joint or failure welding product in time.
Summary of the invention
The purpose of this utility model is to provide for the laser fusion welding fit structure of a kind of voice coil motor rational in infrastructure.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme: the laser fusion welding fit structure of a kind of voice coil motor, including base, terminal and rear reed, described terminal is arranged between base and rear reed and is connected with rear reed by laser fusion welding, it is characterized in that: described rear reed is provided with rectangular through holes, described through hole is positioned at the edge of terminal cooperation position, through hole length and the consistent in or greater than termination width of terminal length.
Further, as a kind of preferred version, described through hole outward flange is concordant with terminal outward flange, and through hole inward flange is at 1/4 width place of the width of terminal adapted space.
Terminal upper surface is square, is of a size of 0.5mm*0.5mm or length and width are all higher than 0.5mm.
Further, as a kind of preferred version, described terminal is fixed by burying forming and base.
Compared with prior art, the beneficial effects of the utility model are: may insure that by this structure and better carry out product welding, and realize visual examination welding effect; Can better reaching the effect of welding on the one hand, by inspection, another aspect can confirm that welding effect prevents rosin joint and failure welding product from flowing out, steady production efficiency, it is ensured that produce the quality of product.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, this utility model being further described, illustrative examples and explanation in this utility model are used for explaining this utility model, but are not intended as restriction of the present utility model.
The laser fusion welding fit structure of a kind of voice coil motor as shown in Fig. 1 Fig. 2 Fig. 3, including base 1, terminal 2 and rear reed 3, described terminal 2 is arranged between base 1 and rear reed 3 and is connected with rear reed 3 by laser fusion welding, it is characterized in that: described rear reed 3 is provided with rectangular through holes 4, described through hole 4 is positioned at the edge of terminal 2 cooperation position, through hole 4 length and terminal 2 length consistent in or greater than terminal 2 width. Terminal 2 upper surface is square, is of a size of 0.5mm*0.5mm or length and width are all higher than 0.5mm.
As a kind of preferred version, described through hole 4 outward flange is concordant with terminal 2 outward flange, and through hole 4 inward flange is at 1/4 width place of the width of terminal 2 adapted space.
As a kind of preferred version, described terminal 2 is fixed with base 1 by burying forming.
In actual production, the design of melting welding point is in the centre position of the square position of terminal 2, and such laser spots can better carry out melting welding, and the diameter of laser spots just covers 1/5 width ~ 1/6 width of rectangular through holes 4, conveniently carry out visualization, find rosin joint or bad welding in time.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every technology deformation made according to the technical solution of the utility model, each falls within protection domain of the present utility model.
