Description
Technical field
The present invention discloses a kind of anti-shake CD-ROM drive motor, particularly a kind of coil production method of screw seat in anti-shake CD-ROM drive motor.
Background technology
The structure of anti-shake CD-ROM drive motor is all to have independently coil on four diagonal angles, each coil is independently switched on, by the size control of electric current, the hoisting depth of screw seat is adjusted, carry out the angular deflection of screw seat and camera lens, the object of deflection is because in photographic process, because the shake of hand causes camera lens to depart from target, camera lens need to carry out angular deflection adjustment and find target, and camera lens is by the Current Control of coil on motor, carry out the deflection of angle, produce anti-shake effect.Therefore, the quality of coil and the quality of installation directly affect the anti-trembling function of motor.
The end of a thread and spring welding meeting is in the past because of camber of spring or cause both loose contacts, need to utilize tin cream to make bridge, both is connected, but can in the time falling on the ground, cause broken string or disconnected weldering.Processing step for the wire winding of each screw seat in prior art is as follows:
The first step: separate single coiling, altogether to prepare four coils;
Second step: be stained with glue on four diagonal angle boss of screw seat;
The 3rd step: utilization is manual four single line coils, sticks respectively on four diagonal angle boss;
The 4th step: utilize the black glue fixed coil of manual point;
The 5th step: screw seat is put in baking box and toasted, and the manual the end of a thread of repairing of recycling, puts the end of a thread in metallic channel into.
The problem of its existence mainly comprises: 1, supplier need to be equipped with a large amount of personnel and is engaged in single group coil and is assembled on screw seat; 2, cost is relatively costly, is difficult to that cost is low subtracts, and screw seat is bad and scrappage is higher; 3, production capacity is very low, fails to reach production in enormous quantities needs.
There is following problem in the coil production technique of present anti-shake CD-ROM drive motor, causes the anti-shake function of motor be affected or lose anti-trembling function completely, and this problem comprises:
1. the laminating of coil and screw seat adopts by hand, and yield is low, and efficiency is low, and cost of labor is high:
Present production technology is the coil groups that coil winding machine first lays out elliptical shape, then by hand each coil groups is buckled in to the button line boss on the secondary diagonal angle of lens mount four, then fills glue, and coil groups is fixed on boss.Recycling is manual to be guided to the end of a thread of each coil groups in the wire lead slot of lens mount separately, and preparation and spring weld.One has 4 coil groups and 8 the end of a thread, and this group technique is not only consuming time, and in lead-in wire process employee's the end of a thread that easily fractures, cause defective products.
2., easily there is dry joint or rosin joint in the tight welding of coil and spring join dependency the end of a thread and spring:
Each the end of a thread of coil groups is guided to and is prepared in wire casing and spring welds, and the end of a thread and spring in wire casing still maintain a certain distance, and to be that the machining accuracy of groove is low avoid spring with the end of a thread to object, and spring can be developed in the plane of screw seat.Owing to having space between the end of a thread and spring, so will lean on the bridge of tin cream as both, both are welded together.Because differ in space, the unsteadiness of welding procedure and tin cream are more weak after solidifying, and depend merely on tin cream and make the mode of both bridges and can easily cause dry joint or rosin joint as welding, i.e. failure welding, cannot conduct electricity.
Summary of the invention
For the coil of screw seat in the above-mentioned of the prior art anti-shake CD-ROM drive motor of mentioning, adopt artificial installation, efficiency is low, and easily there is the shortcoming of dry joint or rosin joint, the invention provides the coil production method of screw seat in a kind of new anti-shake CD-ROM drive motor, its adopt automatic coil winding machine by enamelled wire automatic winding to four jiaos of boss of screw seat, simplified processing step, and the end of a thread also can be more closely and spring contact, do not need through tin cream as bridge.
The technical scheme that the present invention solves its technical problem employing is: a kind of coil production method of screw seat in anti-shake CD-ROM drive motor, the method is to be respectively equipped with automatic winding terminal in the upper and lower surface at four jiaos of places of screw seat, be respectively equipped with convex closure at four sides of screw seat, form coil by automatic coil winding machine automatic winding on automatic winding terminal and convex closure, automatic coil winding machine by coiling after the end of a thread end directly on the wrapping post of screw seat, then the reserved spring of keeping away a hole is anchored on fixed leg, then carries out a tin cream, welding operation.
The technical scheme that the present invention solves its technical problem employing further comprises:
Described method step is as follows:
(1), utilize automatic coil winding machine enamelled wire on four jiaos one upper wrapping post above screw seat, and leave first the end of a thread at upper wrapping post place;
(2), utilize automatic coil winding machine that enamelled wire is continued to be wrapped on a convex closure;
(3), utilize automatic coil winding machine that enamelled wire is continued to be wrapped on the lower wrapping post that the upper wrapping post with step (1) below screw seat is corresponding, and leave second the end of a thread;
(4), repeating step (1) is to (3), till all winding enamelled wire on the wrapping post of four jiaos of screw seats;
(5), 8 the end of a thread respectively around to the wrapping post of 4 of screw seat top and bottom;
(6), between the position of 8 the end of a thread and wrapping post, put glue;
(7), on screw seat and below all stick spring;
(8), go up tin creams corresponding to 8 reserved hole place's points of keeping away of upper lower spring;
(9) utilize laser to weld in 8 tin cream places;
(10), complete automatic winding and welding procedure.
The invention has the beneficial effects as follows: realize automatic winding, avoided hand winding operation, therefore can directly reduce cost of labor, reduce component unit price.The end of a thread, around the fixing pillar of screw seat, can avoid the end of a thread broken string bad in assembling camera lens process, and spring and screw seat are bonding more firm.Automatic winding mode is faster more than five times than hand winding speed, therefore can shorten the process time, cost-saving, improves the level of bidding.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
