Abstract
The invention discloses a production technology for rapid molding of a voice coil motor. The technology comprises the following steps that (1) a whole row of terminals is etched; (2) a single terminal is removed from the whole row of terminals; (3) the terminal serves and a mold insert and sent to a cavity of an injection die; (2) the injection die carries out secondary injection molding to prepare a lower cover with terminals; and (5) the voice coil motor is prepared by an existing method after preparation of the lower cover. The terminals are processed in the etching manner, a cold stamping die is not needed, processing time is short, the cost is lower, the etched terminals are flat-plate-shaped, a secondary injection molding process does not need pins for positioning, holes for fixing the pins do not form in the lower cover, a process of heating and backing glue is avoided, phenomena that steam reaches a lens via the holes and causes inclination of the lens and fuzzy images are avoided, and the product quality is high.
Description
Technical field
The present invention relates to a kind of camera installation, more particularly to a kind of production technology of the rapid shaping of voice coil motor.
Background technology
As shown in Figure 1A, Figure 1B, Fig. 1 C, the terminal commonly used is processed by the way of punching press, need to open up stamping die
Tool, Design of Dies, manufacture time it is longer, and, the terminal 10 ' for stamping out in inverted L-shaped, when secondary injection molding is carried out,
It is to place terminal 10 ' to install on slide block 1 ', and it is fixed with pin 2 ', therefore, on the product of lower cover 20 ' of injection mo(u)lding, meeting
There is the hole 201 ' for wearing pin 2 '.After voice coil motor 40 ' is assembled, in follow-up optical filter 30 ' and voice coil loudspeaker voice coil are crossed
In the assembling process of motor 40 ', glue was coated in into the bottom surface of optical filter 30 ', then the optical filter 30 ' of crossing for scribbling glue was superimposed on
The top surface of voice coil motor 40 ', then cross optical filter 30 ' and the feeding oven cooking cycle of voice coil motor 40 ' that are superimposed are fixed.Glue
During water heated baking, steam can reach camera lens by hole 201 ', and in heating process, because corresponding active force
Cause camera lens to incline, occur as paste phenomenon.
The content of the invention
It is an object of the invention to provide a kind of life of the rapid shaping of the high voice coil motor of with short production cycle, product quality
Production. art.
For achieving the above object, technical solution of the invention is：
The present invention is a kind of production technology of the rapid shaping of voice coil motor, is comprised the following steps：（1）Etch the end of entire row
Son；（2）Single terminal is broken from the terminal of entire row；（3）Send terminal as mold insert into molding mold cavity；（4）Note
Mould quadric injection mould, is obtained the lower cover with terminal；（5）Voice coil loudspeaker voice coil horse is made in the method assembling that lower cover is had after completing by habit
Reach.
Described terminal is in tabular, is vertically plugged on lower lid.
After using such scheme, because terminal of the present invention is processed by the way of etching, without the need for opening up Cold pressing die
Tool, process time is short, and cost is relatively low, and etches the terminal for coming in tabular, need not during secondary injection molding
Pin is positioned, lower cover will not form the hole for fixing pin, it is to avoid during glue heated baking, steam can pass through
Hole reaches camera lens, and because corresponding active force causes camera lens to incline in heating process, occurs, as the appearance of paste phenomenon, producing
The quality of product is high.
Below in conjunction with the accompanying drawings the present invention is further illustrated with specific embodiment.
Description of the drawings
Figure 1A is the axonometric drawing for commonly using terminal；
Figure 1B is the schematic diagram for commonly using terminal secondary injection molding；
Fig. 1 C are to commonly use the axonometric drawing that optical filter is superimposed on lower lid；
Fig. 2 is the front view of terminal of the present invention；
Fig. 3 is that the present invention crosses the axonometric drawing that optical filter is superimposed on lower lid.
Specific embodiment
As shown in Figure 2 and Figure 3, the present invention is a kind of production technology of the rapid shaping of voice coil motor, is comprised the following steps：
（1）The terminal 1 of entire row is etched, terminal 1 is in tabular,；
（2）Single terminal 1 is broken one by one from the terminal 1 of entire row；
（3）Send single terminal 1 as mold insert into molding mold cavity；
（4）Injection mold quadric injection mould, is obtained the lower cover 2 with terminal 1, and terminal 1 is vertically plugged on lower cover 2.
The lower cover 2 with terminal 1 for completing is then assembled into voice coil motor 4, and this part makes packaging technology and practises to be had
Technology, does not elaborate herein.
The voice coil motor 4 completed by the present invention, process time is short, and cost is relatively low；Also, in follow-up processing,
The bottom surface gluing of optical filter 3 will be crossed, cross optical filter 3 and be superimposed on voice coil motor 4, by what is be superimposed optical filter 3 and sound are crossed
Coil motor 4 is sent into oven cooking cycle and is fixed, and because terminal 1 is in tabular, is vertically plugged on lower cover 2, and lower cover 2 will not be formed and is used for
The hole of fixing pin, it is to avoid during glue heated baking, steam reaches camera lens by hole, and in heating process
Because corresponding active force causes camera lens to incline, occur as the appearance of paste phenomenon, the quality of product is high.
The above, only present pre-ferred embodiments, therefore the scope of present invention enforcement can not be limited with this, i.e., according to
The equivalence changes that scope of the present invention patent and description are made and modification, all should still belong to the model that patent of the present invention covers
In enclosing.
