Problems solved by technology

With the development of the times and the advancement of mobile phone camera technology, the size of the voice coil motor is getting smaller and smaller, and the effective stroke requirements of the voice coil motor are getting higher and higher, which in turn requires the thickness of the lens frame to be thinner and thinner, but thin The strength of the optimized lens holder itself will be reduced, and the torque will not meet the specifications, which will affect the locking effect of the lens, thereby affecting the reliability of the module

Abstract

The present invention proposes a voice coil motor, including a base, a casing, a lower elastic piece, a lens holder, a coil, a magnet, an upper elastic piece, an upper cover pressing plate and pins, the lower elastic piece, the lens holder, the coil, and the magnet , the upper elastic piece and the upper cover pressing plate are sequentially arranged between the base and the shell, the stitches are arranged on the base, the lens holder and the coil are integrally formed, and the coil is wound around on the outer side of the lens holder. The invention also proposes a manufacturing method of the voice coil motor.

Description

technical field [0001] The invention relates to a motor, especially a voice coil motor and a manufacturing method thereof. 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 electronic products (such as digital cameras, mobile phones, digital video cameras, etc.). With the development of the times and the advancement of mobile phone camera technology, the size of the voice coil motor is getting smaller and smaller, and the effective stroke requirements of the voice coil motor are getting higher and higher, which in turn requires the thickness of the lens frame to be thinner and thinner, but thin The strength of the optimized lens holder itself will be reduced, and the torque will not meet the specifications, which will affect the locking effect of the lens and further affect the reliability of the module. Contents of the invention [0003] In view of the above situatio...
