Abstract
The invention relates to the field of image pick-up equipment, and discloses an assembly method of a rotor in a voice coil motor. Firstly, a coil sleeves the upper part of a carrier, and the coil and the carrier are fixedly connected; then an outer ring spring of a lower spring is fixedly connected with the bottom of the carrier; finally an inner ring spring of the lower spring is fixedly connected with a tapping line of the coil through a resistance spot welding mode; the resistance spot welding basically comprises the steps of firstly lapping the tapping line on a spring piece of the inner ring spring, then pressing the tapping line through a spot welding head, electrifying the spot welding head, and finally melting and then welding the tapping line and the spring piece of the inner ring spring into a whole body through high temperature instantaneously produced by the electrified spot welding head. Compared with the prior art, the method has the advantages that tin wires and scaling powder are not required to be used, situations that the tine wires and the scaling powder are splashed and the soldering tin amount is not easy to master cannot be caused, the carrier cannot be scalded, the yield is high, the technology is simple, the efficiency is high, the phenomenon of misoperation caused by manual spot welding is also avoided, and false soldering and inveracious soldering cannot occur.
Description
Technical field
The present invention relates to apparatus for making a video recording field, particularly the assembly method of mover in a kind of voice coil motor.
Background technology
As Fig. 1, the mover of voice coil motor is by coil 1, carrier 2 and upper spring 3 form, upper spring 3 is made up of (as Fig. 2) interior coil spring 31 and cycle spring 32, when assembling mover, glue is first used to be fixedly connected with on the top of coil 1 with carrier 2, then the cycle spring 32 of lower spring 3 is being fixedly connected with the bottom glue of carrier 2, finally the tap line 11 of coil 1 and the spring leaf 311 of coil spring 31 in lower spring 3 are welded together, ensure current lead-through, this welding is generally that soldering connects, even if with electric iron high-temperature digestion solder stick, spring leaf 311 and coil 1 tap line 11 are welded together, ensure current lead-through, as shown in Figure 3.Easily cause following bad in the process of welding: solder horn scorches carrier 2(because carrier 2 is generally working of plastics), scolding tin 5 and scaling powder splash, scolding tin 5 amount is too much or how many, complex process and yield is low, efficiency is not high.
Summary of the invention
goal of the invention:for problems of the prior art, the invention provides the assembly method of mover in a kind of voice coil motor, do not need additionally to use solder stick and scaling powder, carrier can be avoided to be ruined, technique is simple, yield and efficiency higher.
technical scheme:the invention provides the assembly method of mover in a kind of voice coil motor, described mover is made up of coil, carrier and the lower spring with interior coil spring and cycle spring, and its assembly method comprises the following steps: S1: coil is enclosed within upper carrier peripheral and the two be fixedly connected with; S2: the cycle spring of lower spring is fixedly connected with the bottom of carrier; S3: coil spring in lower spring is fixedly connected with the tap line of coil; In described S3, described interior coil spring is fixedly connected with the mode of described tap line by resistance spot welding.
Further, in the described process interior coil spring and tap line are fixedly connected with by resistance spot welding, following sub-step is comprised: ridden over by described tap line on the spring leaf of interior coil spring; Described tap line is compressed with spot welding head; Be energized to described spot welding head; The high temperature produced instantaneously after the energising of described spot welding head welds together after being melted by the spring leaf of tap line and interior coil spring.
beneficial effect:in the present invention, in the process that the spring leaf of coil spring in the tap line of coil and lower spring is welded together, use the mode of resistance spot welding, spot welding head is directly pressed on tap line and spring leaf by the mode of this spot welding, then be energized, the high temperature that spot welding head produces instantaneously can weld together after tap line and the fusing of partial spring sheet, and technique is simple, and efficiency is high; Owing to not needing to use solder stick and scaling powder in whole process, so can not cause the situation of scolding tin and scaling powder splashing and the bad assurance of soldering tin amount, yield is higher; Spot welding head in this method is relative fixing with the position needing to weld, and can not scorch carrier, it also avoid the maloperation phenomenon of artificial spot welding, greatly reduce the fraction defective of this link; In addition, in pinpoint welding procedure, only need the parameter such as the voltage of point of adjustment welding machine, pressure, time just can adjust the bonding strength of tap line and spring leaf easily, ensure not dry joint and rosin joint.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
In the present invention, the mover of voice coil motor is by coil 1, carrier 2 and the lower spring 3 with interior coil spring 31 and cycle spring 32 form, when assembling, first coil 1 is enclosed within carrier 2 top peripheral, then with glue, the two is fixed, then with glue, the cycle spring 32 of lower spring 3 is fixedly connected with bottom carrier 2, finally the tap line 11 of coil 1 is ridden on the spring leaf 311 of interior coil spring 31, the spot welding head 4 of mash welder is aimed at tap line 11 to be pressed on spring leaf 311 by tap line 11 from the top down, by the time when pressure reaches preset pressure, mash welder is energized just to spot welding head 4, spot welding head 4 can obtain high temperature instantaneously, this high temperature is enough to tap line 11 and partial spring sheet 311 to melt, because spot welding head 4 also has certain pressure to the two while fusing, thus just achieve being welded and fixed between tap line 11 and spring leaf 311, ensure that the current lead-through between coil 1 and interior coil spring 31, as shown in Figure 4.
Above-mentioned embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to Spirit Essence of the present invention or modification, all should be encompassed within protection scope of the present invention.
