At present, the dual-camera focusing device for mobile phones in the market requires the combination of two single focus motors to achieve the dual-camera effect, but its structural design is more complicated, the product is not easy to be formed, and the accuracy cannot be guaranteed.
A reporter from Science and Technology Daily recently learned from Baotou Jiangxin Micromotor Co., Ltd. that a high-precision zoom motor for cameras based on new permanent magnet materials has begun mass production. This motor can effectively solve the above difficulties. This kind of automatic zoom motor independently developed by the company has a side length of 8.5 mm and a thickness of 2.9 mm. It is only the size of a nail cover and requires 19 processes to complete. It has reached the domestic leading level.
Baotou Jiangxin Micro-motor Co., Ltd.'s research and development team finally developed a spring-loaded sheet for this dual-camera autofocus device. The structure is simpler and the design is reasonable. The integrated design makes the product easy to process and shape. Out of space.
Xu Deguang, general manager of the company, told reporters: "This new camera micro-automatic zoom motor adds high-row permanent magnet materials. Its core technology is to use magnets and coils to generate kinetic energy and drive the motor to move up and down within 30 microns. The computer chip automatically captures the sharpest image and fixes the focus. It is a very precise electronic instrument. "
After the technology is formed, in order to make the VCM motor (that is, the voice coil motor is a device that converts electrical energy into mechanical energy and realizes linear and limited swing angle movement), the closing is more accurate and the qualification rate is higher. The company's research and development team also introduced International advanced equipment, realizing 10 automatic production line assembly line operations, using laser scanning operation and visual automatic operation to control the error within 1 micron.
After the company's staged projects are all in production, it can achieve an annual output of 100 million autofocus motors for mobile phone cameras. Industry experts believe that this new zoom motor has a broad application prospect, not only for mobile phone cameras, but also for electronic education products, children's watches, car systems, drones, smart robots and smart home products.
