The invention provides a spring sheet and a voice coil motor assembly. The spring sheet is provided with at least two positioning holes and at least one first dispensing groove, wherein the first dispensing groove communicates with the two adjacent positioning holes in the spring sheet. The voice coil motor assembly comprises the spring sheet and a magnet bearing frame, the magnet bearing frame is provided with at least two positioning columns, the positioning columns are inserted into the positioning holes in the spring sheet, and adhesive glue for fixedly connecting the spring sheet with the magnet bearing frame is accommodated in the first dispensing groove. According to embodiments of the invention, the spring sheet is provided with the dispensing groove communicating with the two adjacent positioning holes so that the dispensing space is extended, spilling glue is prevented from axially flowing to the inside of the magnet bearing frame along the magnet bearing frame, accordingly, the quality of products is not affected, and the spring sheet and the magnet bearing frame are bonded more firmly.
Description
technical field [0001] The invention relates to voice coil motor technology, in particular to a shrapnel and a voice coil motor assembly. Background technique [0002] The voice coil motor assembly generally includes a housing, a magnet carrier in the housing, a movable barrel accommodated in the magnet carrier, and two shrapnels installed at both ends of the magnet carrier; the movable barrel is used for assembly with the lens barrel And the outside is wound with wires, and the movable tube is suspended on two shrapnels and can move along the axial direction. Magnets are arranged on the magnet bearing frame for generating magnetic force with the wires outside the movable cylinder. [0003] Wherein, the four corners of each elastic sheet are usually provided with four positioning holes, and correspondingly, the four corners of the end face of the magnet carrier connected to the elastic sheet are provided with positioning posts, and the positioning posts are adapted to the p...
