Abstract

The invention relates to a base assembly, a voice coil motor and a manufacturing method of the voice coil motor, the base assembly comprises a base, a metal circuit and a reed, the base comprises a plastic base formed at a time, the plastic base comprises a top surface and a bottom surface, and the reed comprises an inner fixing part, an outer fixing part and a deformation part. The base further comprises a plastic block formed on the plastic base through secondary injection molding, and the plastic block wraps the outer fixing part so that the outer fixing part can be embedded between the bases. According to the seat assembly, the reed is firstly positioned on the plastic base so as to be welded with the metal circuit embedded in the plastic base, and then the plastic block is molded in a secondary injection molding manner, so that the plastic block covers the outer fixing part of the reed; therefore, the stable fixation between the external fixing part and the plastic base and the stable electrical connection between the external fixing part and the metal circuit are realized.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a base assembly, a voice coil motor and a manufacturing method thereof. Background technique [0002] The existing voice coil motor usually includes a base, a metal circuit embedded in the base, a lower reed electrically connected to the metal circuit, a coil, and a magnetic structure interacting with the coil. With the development of miniaturization requirements of electronic equipment, the structure of miniature digital cameras is becoming more and more miniaturized, and the requirements for the driving structure of the voice coil motor-camera module are also getting higher and higher, especially for cameras used in smart phones Components, due to the frequent use of mobile phones, thinner technical requirements, and accidents such as falling and bumping are more likely to occur during use, so the requirements for the stability and reliability of voice coil motors for mo...
