Three-jaw positioning automatic focusing module

Abstract

The utility model discloses a kind of three-jaw positioning automatic focusing module, supporting plate, circular ring rotating module being set on supporting plate, central positioning plate being set on circular ring rotating module and being used for positioning lens module, positioning clamp jaw module for cooperating with the clamping lens focusing ring and being set on circular ring rotating module three groups of equal circumference distribution and lift driving module for being set on the upper of circular ring rotating module and being used for the relative separation of lower pressure push positioning clamp jaw module. Three groups of positioning clamp jaw module are set on circular ring rotating module to lens module clamping and fixing, positioning clamp jaw module is driven around center by circular ring rotating module to realize focusing to lens module, and lens module is positioned by central positioning plate, ensure that lens module keeps stable during focusing process, and three groups of positioning clamp jaw module are pushed away from the clamping of lens module by lift driving module lower pressure, to realize lens module assembly clamp.
