Problems solved by technology

[0004] However, manual bending of pins in the assembly process not only increases the process and cycle of the assembly process, but also cannot effectively control the position, angle and length of each bending. Bend the pins at the same position to the same angle and length, thereby reducing the yield rate and affecting the subsequent assembly of the voice coil motor

Abstract

The invention provides an elastic sheet bending device which comprises a bearing table, a bending element and a clamping element, wherein the clamping element is arranged between the bearing table and the bending element; the bearing table comprises a bearing surface and a side surface which is adjacent to the bearing surface; and the bending element comprises a main part and a press head which extends along one side of the main part. The length of the press head from the body to the direction of extending side is greater than the thickness of the clamping element, and the distance between the press head and the side surface is greater than the thickness of the elastic sheet to be bent. The invention also provides an elastic sheet bending method for bending elastic sheets by utilizing the elastic sheet bending device.

Description

technical field [0001] The present invention relates to the technical field of voice coil motors, in particular to a shrapnel bending device and a shrapnel bending method using the bending device. Background technique [0002] The voice coil motor has the advantages of small size, low power consumption and low price, and is suitable as an actuator in 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). [0003] A common voice coil motor mainly includes a fixed frame with openings at both ends, a movable tube with openings at both ends that is movably installed in the fixed frame, a shrapnel and is used to carry the fixed frame, movable tube and shrapnel. and a carrier fixed to the fixture. The movable barrel is used to install components such as lens barrels or zoom lense...
