Ultra-thin VCM motor mounted in buckle type way

Abstract

The invention discloses an ultra-thin VCM motor mounted in a buckle type way. The ultra-thin VCM motor comprises a base; a power-on terminal is arranged on the surface of the upper end of the base; a lower spring piece is arranged at the upper end of the base; a dustproof ring is arranged between the lower spring piece and the base; contact type elastic piece electrodes are symmetrically arranged on the outer side of the dustproof ring; a carrier is arranged on the upper side of the lower spring piece; four corners at the upper end of the carrier have stepped structures; coils are arranged on the surface of the outer side of the carrier; magnets are correspondingly arranged on the outer sides of the coils; an upper spring piece is arranged on the upper side of the magnet; and a shell is arranged on the upper side of the upper spring piece. According to the ultra-thin VCM motor mounted in the buckle type way, the production technology is simplified, the cost is reduced, and the reduction of powder that is most concerned in the module is facilitated; by matching with the motor structure, a chip module can be directly implanted with a mobile phone main board in a patch manner; the use of FPC and sockets on the module is directly reduced; and due to the simplified technology and the reduction of manpower cost, the total cost of the module can be reduced by 20-30%.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a buckle-mounted ultra-thin VCM motor. Background technique [0002] The VCM is a motor that uses the magnetic field generated by the current flowing in the speaker's voice coil and the magnetic field generated by the permanent magnet to use the speaker's diaphragm. The advantage of the VCM is that it consumes less power, is smaller and cheap, and it has high precision in operation displacement, making it useful for adjusting the gap between the lens and the image sensor in the camera module. enough. [0003] VCM motor, also known as voice coil motor, is mainly used in camera modules as the core actuator in optomechanical integration. It has the function of carrying the lens and linearly and precisely moving the lens by changing the motor current, so as to realize the zoom function of the camera module for far focus and near focus. [0004] At present, the assembly process ...

AI Technical Summary

Problems solved by technology

[0004] At present, the assembly process of VCM motors and chip components in the industry is complicated, and the number of parts is large, resulting in high module costs; and the height of the motor is high, resulting in the height of the module is usually greater than 4.2mm, which restricts the thickness of the mobile phone, and rosin is easy to produce during welding. , tin beads and other foreign matter pollution, high module height phenomenon
