Abstract

A miniature tilt-shift type optical anti-vibration voice coil motor structure facilitating production comprises a base, a shell, a lens carrier, three or more magnets, an elastic material, a coil carrier, coils and bosses, wherein the number of the coils and the number of the bosses are each equal to that of the magnets. The base and the shell are fixedly installed together, the lens carrier is installed on the coil carrier through the elastic material, the bosses are installed on the outer side of the coil carrier, each coil is wound around the corresponding boss, the magnets are fixedly installed on the lens carrier, and the magnets are arranged corresponding to the coils. Compared with previous technologies, the motor structure can be simplified effectively; meanwhile, the number of mechanical and electronic connection processes needed during production assembling can be reduced, the motor structure supports the process that the coils are directly wound around the coil carrier, mass production is facilitated, and even full automatic mass production can be achieved. Thus, compared with existing technologies, the motor structure can improve production efficiency and increase the percent of pass, reduce the number of assembling staff, reduce material cost and meanwhile enhance mechanical crashworthiness.

Description

technical field [0001] The invention discloses a voice coil motor, in particular a structure and an assembly method of a miniature shaft-shifting optical anti-vibration voice coil motor which are favorable for production. Background technique [0002] Nowadays, the technology of miniature optical anti-shake voice coil motor has been widely used in high-end mobile phones, which can effectively reduce the chance of taking blurred photos in low-light environments and disturbing shaking in videos. However, compared with general auto-focus motors, the design of anti-shake voice coil motors is more complicated, and the yield and efficiency of production are lower. Therefore, the technical description has not yet been popularized in middle-end and low-end mobile phones, and most mobile phone users still cannot enjoy the benefits brought by the anti-shake technology. [0003] Miniature optical anti-shake voice coil motors can be divided into three categories, their names and anti-s...
