Two-dimensional scanning micromirror based on electromagnetic driving

Abstract

The utility model relates to the field of two-dimensional code scanning micromirrors, and discloses a two-dimensional scanning micromirror based on electromagnetic drive, which comprises a base, the middle part of the base is movably connected with a cylinder body, the inner bottom of the cylinder body is fixedly connected with a partition plate, the middle part of the partition plate is provided with a bearing seat, the top end of the inner ring of the bearing seat is fixedly connected with a magnetic ring, and the top end of the inner ring of the bearing seat is fixedly connected with the magnetic ring. An aluminum cylinder is movably connected to the inner side, close to the magnetic ring, of the top of the partition plate, a guide rod is fixedly connected to the middle of the top end of the partition plate, the middle of the guide rod is slidably connected to the interior of the column body, a mounting plate is fixedly connected to the top end of the column body, and a two-dimensional code scanning micromirror is mounted in the middle of the top end of the mounting plate. According to the utility model, the focal length is adjusted by controlling the two-dimensional code scanning micromirror on the mounting plate to continuously move up and down in the cylinder in an electromagnetic driving manner, so that the two-dimensional code scanning micromirror can quickly complete the scanning work of a two-dimensional code, and convenience is brought to merchants and users.
