The invention discloses an automatic test system for vibration motor production. An annular pressing plate is pushed to get close to a vibration motor so that a piston plate and an annular pressing plate clamp and fix the vibration motor. Thus, air enters the air bag through an air guide hole. An air bag expands and is clamped into an air bag groove, connection between a sound insulation cover anda fixed base is achieved. An two-dimensional code is scanned through a two-dimensional code collecting and lighting unit, and specification parameters of the vibration motor are automatically obtained. The electric push rod is controlled to push, so that the sound insulation plug-in blocks the jack to insulate sound. An exposed conductive metal part of a motor power supply wire is contacted with a conductive elastic sheet. Meanwhile, a noise sensing unit reaches the center of the annular pressing plate and collects noise generated by the vibration motor, and the noise sensing unit is matched with the sound insulation cover and the sound insulation inserting piece which are made of the sound absorption materials, so that interference caused by internal sound wave reflection can be reduced while external noise is isolated, and pickup accuracy is improved.
Description
technical field [0001] The invention relates to the field of automatic testing of motors, in particular to an automatic testing system for vibration motor production.
