[Prior Art] The voice coil motor has the advantages of small size, low power consumption, and low price, and is suitable as an actuator for camera modules (such as digital cameras, mobile phones, digital video cameras, etc.) (see Design of a voice) Coil motor used in the focusing system of a digital video camera, Magnetics, IEEE Transactions on Volume 41, Issue 10, Oct. 2005 Page(s): 3979-3981). A common voice coil motor mainly includes a fixed frame with two ends open, a movable loading tube that is movably mounted at both ends of the fixed frame, a spring piece, and is used for carrying the fixed frame, the movable loading tube and the elastic piece. And a carrier fixed to the holder. The movable barrel is used to mount components such as a lens barrel or a zoom lens in the lens module.

In the process of making the shrapnel, the body and the lead are usually formed on the same plane, and the pin is bent by hand relative to the body during the subsequent assembly process, and the bent shrapnel and other components are assembled into a voice coil motor. However, the use of artificial bending pins in the assembly process not only increases the process and cycle of the assembly process, but also effectively controls the position, angle and length of each bending. It is difficult to ensure that the same type of shrapnel made by different workers is 201018979 Bend the same angle to the same position in the same position and ώ, do the month > ^ and length, thereby reducing the yield rate, affecting the subsequent assembly of the voice coil motor. In view of this, it is necessary to provide a shrapnel bending device and a shrapnel bending method which can effectively improve the production efficiency and bending quality of the shrapnel. SUMMARY OF THE INVENTION A method of bending a shrapnel will be described below with reference to specific embodiments.

At the same time, the semi-cylindrical bulge: causes the shrapnel to have a certain over-curve, so that the ram has a certain resilience to ensure its bending angle. Qin (4) The bullet of this technical solution; ^ folding device _ two compression elastic; advance::: elastic smashing can simultaneously bend a plurality of elastic pieces, improve the bending efficiency 'and can effectively guarantee the bending quality of the same type of shrapnel . Referring to FIG. 2 to FIG. 6', the embodiment of the present technical solution further provides a method for bending a f-folded elastic piece by using a shrapnel f-folding device (10), which comprises the following steps: setting 1〇ίΓ Providing the material buckling elastic piece 200 and the elastic ridge folding piece 210 as described above, the to-be-bent elastic piece 200 includes a body 210, a pin 220 extending to the body π, β 夕, and a side connected to the body 210 and located on the opposite side of the leg 220 The foot is 23 〇. The field body body 210 can be designed as a plate of any shape according to the need, and the pins 220 匕 and the external circuit are connected to each other, and the side legs are scraps in the process of punching a plurality of pieces of shrapnel. The body 210, the pin 22 〇 is disposed coplanar with the trim 23 。. In this embodiment, the body 210 is a square plate body having a receiving through hole 211 and an elastic portion 212 surrounding the receiving through hole 211. The through hole 211 is received for light to pass through and to enter a driven component (such as a lens module). The four corners of the body 210 are respectively provided with guide holes 213 for the positioning post 148 to pass through and position the body 210. The pin 220 needs to be bent 90 degrees from the connection between the body 210 and the pin 220 to obtain the shrapnel that is required to be fabricated in this embodiment. Of course, only the indenter pin 220 can be indented as needed. In the second step, the elastic piece 200 to be bent is placed on the boring stage 14 of the elastic piece bending device 100. Referring to FIG. 3, the body 210 of the elastic sheet 200 to be bent is placed in the bearing surface 142 of the stage 14, and the four guiding holes 213 of each elastic piece 200 are respectively fixed and fixed through the four positioning posts 148 of each group. The pin 220 extends from the bearing surface 142 to the side of the stage 14 having a recess 146. In the third step, the clamping member 20 is pressed to fix the body 210 of the elastic piece 200 to be bent. φ Referring to Fig. 4, the two first guide holes 26 at both ends of the clamp member 20 are respectively opposed to the two guide posts 16, and the clamp member 20 is fitted to the guide post 16. Since the stage 14 and the holding member 20 are both magnetic materials, and the clamping member 20 is inserted into the guide post 16, the loading table 14 and the holding member 20 can press and fix the elastic sheet 200 to be bent by the action of the magnetic force. The fourth step is to insert the bending member 30 into the pin 220 of the bending elastic piece 200. Referring to FIG. 5, the two second guiding holes 36 at the two ends of the bending member 30 are respectively opposed to the two guiding columns 16, respectively. The bend 30 is nested into the guide post 16.

The (four) folding member 3G and the clamping member 20, = the rear elastic piece 300 are sequentially taken, as shown in FIG. In the end, it is necessary to remove the single piece of shrapnel from the two-voice motor of the shrapnel 3 (9). In addition, there is no edge: the folding method bends its pins. Compared with the prior art, the elastic piece folding device and the method of the present invention have the following advantages: First, the pressing piece of the loading table and the clamping member is pressed to be the elastic piece and the pressing head of the folding piece is used for the same type of elastic piece. Uniformly = fold, to ensure that the bending position, angle and length of the shrapnel are the same as the bending quality of the shrapnel; secondly, it can improve the efficiency of the shrapnel production at the same time.
