Description

Method for producing coil of screw seat in anti-shake drive motor

Technical field

The invention discloses an anti-shake drive motor, in particular to a coil production method of a screw seat in an anti-shake drive motor.

Background technique

The anti-shake drive motor has four independent coils on each corner. Each coil is independently energized. Through the control of the current, the lifting height of the screw seat is adjusted, and the angle of the screw seat and the lens is deflected. The purpose is because during the photography process, the lens is deflected from the target due to the shaking of the hand, the lens needs to be adjusted by the angle offset to find the target, and the lens is controlled by the current of the coil on the motor to deflect the angle to produce an anti-shake effect. Therefore, the quality of the coil and the quality of the installation directly affect the anti-shake function of the motor.

In the past, the wire ends and springs were welded due to spring deformation or poor contact between the two. It is necessary to use solder paste as a bridge to connect the two, but it will cause wire breakage or broken welding when falling. The process steps of the winding process for each screw seat in the prior art are as follows:

The first step: independent single winding, a total of four coils to be prepared;

Step 2: glue the glue on the four diagonal bosses of the screw seat;

The third step: manually attach four single-line coils to the four diagonal bosses;

The fourth step: using a manual point of black glue to fix the coil;

Step 5: Put the screw seat into the oven for baking, and then use the manual repair of the thread to put the thread into the wire slot.

The main problems include: 1. The supplier needs to be equipped with a large number of personnel to assemble a single set of coils on the screw seat; 2. The cost is relatively expensive, it is difficult to reduce the cost, the screw seat is poor and the scrap rate is high; 3. The production capacity is very high. Low, failed to meet the needs of mass production.

Now, the coil production process of the anti-shake drive motor has the following problems, causing the anti-shake function of the motor to be affected or completely losing the anti-shake function, including:

1. The coil and the screw seat are assembled by hand, with low yield, low efficiency and high labor cost:

The current production process is that the winding machine first winds out the elliptical coil group, then manually fastens each coil group to the buckle line boss on the four opposite corners of the lens holder, and then fills the glue to fix the coil group. On the boss. Then, the wire ends of each coil group are manually guided into the lead slots of the lens holder to prepare for welding with the spring. There are a total of 4 coil sets and 8 wire ends. This group of processes is not only time-consuming, but also easy to break the wire ends during the lead process, resulting in defective products.

2. The connection between the coil and the spring depends on the tight welding of the wire head and the spring, which is prone to false welding or cold welding:

Each wire head of the coil set is led into the wire groove to be welded with the spring, and the wire end and the spring in the wire groove are still kept at a certain distance, so that the processing precision of the groove is low and the wire head avoids the spring, so that the spring can be flattened on the screw On the plane of the seat. Since there is a gap between the wire end and the spring, the solder paste is used as a bridge between the two to weld the two together. Because of the different gaps, the instability of the soldering process and the weakness of the solder paste after curing, the solder paste alone can be used as a bridge to easily cause false soldering or soldering, that is, poor soldering and inability to conduct electricity.

Summary of the invention

In view of the above-mentioned prior art anti-shake drive motor in the anti-shake drive motor, the coil is manually installed, has low efficiency, and is prone to false welding or soldering. The present invention provides a new anti-shake drive motor. The coil housing coil production method uses an automatic winding machine to automatically wrap the enameled wire onto the four-corner boss of the screw seat, which simplifies the process steps, and the wire head can also be in closer contact with the spring, and does not need to pass the solder paste as a bridge.

The technical solution adopted by the present invention to solve the technical problem is: a method for producing a coil of a screw seat in an anti-shake driving motor, wherein the upper and lower surfaces of the four corners of the screw seat are respectively provided with an automatic winding column, and the screw seat 4 Each side of the side is provided with a convex hull, and the coil is automatically wound on the automatic winding bobbin and the convex hull by an automatic winding machine, and the automatic winding machine directly winds the end of the winding end on the winding bobbin of the screw seat. Then, the spring that has reserved the avoidance hole is fastened to the fixed column, and then the solder paste and the welding operation are performed.

The technical solution adopted by the present invention to solve the technical problem thereof further includes:

The method steps described are as follows:

(1) using an automatic winding machine to wind the enameled wire onto an upper winding post at the four corners of the screw seat, and leaving a first wire end at the upper winding column;

(2) using an automatic winding machine to continue winding the enameled wire on a convex hull;

(3) using an automatic winding machine to continue winding the enameled wire around the lower winding post corresponding to the upper winding column in step (1) below the screw seat, and leaving a second thread head;

(4), repeat steps (1) to (3), all the windings on the four corners of the screw seat are wrapped around the enameled wire;

(5), the eight wire ends are respectively wound onto the lower four wire bobbins on the screw seat;

(6), glue between the position of the 8 thread ends and the bobbin;

(7), a spring is attached to the top and bottom of the screw seat;

(8), corresponding to the upper and lower springs of the eight reserved holes to point the solder paste;

(9) using a laser to weld at 8 solder pastes;

(10) Complete the automatic winding and welding process.

The invention has the beneficial effects that the automatic winding is realized, the manual winding operation is avoided, and the labor cost can be directly reduced, and the unit price of the parts can be reduced. The fixed column of the wire head surrounding the screw seat can avoid the wire breakage failure during the assembly of the lens, and the spring and the screw seat are more firmly bonded. The automatic winding method is more than five times faster than the manual winding speed, so the process time can be shortened, the cost can be saved, and the bidding level can be improved.
