Multi-lens micro-motion device module

Abstract

The invention discloses a multi-lens micro-motion device module, and relates to the technical field of optical module manufacturing. The module comprises a shell, a main lens, an auxiliary lens, a lens holder, a main coil, an auxiliary coil and a magnetic ring. The main lens and the auxiliary lens are embedded into the lens holder. The main coil and the auxiliary coil are fixed on the outer surface of the lens holder. The magnetic ring is fixed on the inner surface of the shell. According to the micro-motion device module, an optical structure and a mechanical structure are combined together. The optical structure employs the two or more lenses, and clear imaging is achieved. The mechanical structure employs the two coils to replace an elastic sheet, and the micro-motion device does not rebound when the optical structure moves during imaging. Undesirable exterior and optical phenomena are avoided during manufacturing of finished products, the number of production steps and the labor investment are reduced, the production efficiency and the rate of qualified products are improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of optical module manufacturing, in particular to a multi-mirror micro-motion device module. Background technique [0002] In recent years, the application of optical modules has become more and more widespread, such as mobile phones, computers, and cameras, as well as our closely related electronic products. With the increasingly widespread use of these products, the optical module manufacturing industry has developed rapidly. In addition to the image processor, the micro-movement module is also very important to determine the imaging quality of the optical module when framing. [0003] At present, the micro-motion device module most used in production is a structure designed separately from the optical structure part and the mechanical structure part. During the production process, the two need to be assembled together by hand or by other means. In the assembly process, a lot of manpower and labor are requ...
