Technical Field

[0001] The utility model relates to the technical field of vibration motor production, in particular to a rotor installation mechanism used for vibration motor production. Background Art

[0002] A vibration motor is a motor that can convert electrical energy into mechanical energy. Its working principle is based on the principle of electromagnetism. That is, under the action of a magnetic field, an electric current is passed through the coil, so that the vibration device composed of a magnetic core, a coil and a load vibrates at a high frequency under the action of the magnetic field, thereby realizing the conversion of electrical energy into mechanical energy. In the production process of a vibration motor, the installation of the vibration motor rotor is an important process.

[0003] For example, the disclosed utility model provides "a mobile phone motor rotor assembly device", and its announcement number is: CN209200882U. The patent includes a bottom shell, and a first servo motor is installed at the center of the inner surface wall at the top of the bottom shell. The rotor feeding plate is driven by the second servo motor to rotate at a fixed angle, and the rotor located inside the rotor upper barrel can fall into the rotor slot. The two clamping mechanisms are driven downward by the first electric cylinder, and one of them will assemble the clamped rotor into the stator to complete the transfer work.
