Automatic testing device for vibrating motor production

Abstract

The invention discloses an automatic testing device for vibrating motor production. The automatic testing device for vibrating motor production comprises a feeding belt, a testing jig and an NG box, the feeding belt is installed at one end of a rack, and a discharging belt is installed at the other end of the rack. When vibrating motors are placed on limiting grooves of motor positioning plates atone ends of testing supports, fourth air pressure rods begin to extend to drive the bottom ends of fixed chucks connected with connecting lugs to move to two ends, then the fixed chucks are driven torotate in the limiting grooves, meanwhile after the vibrating motors are fixed in motor positioning grooves with the help of spring assistance, positive and negative pole testing fixtures are connected with the vibrating motors for performance detection, the waveform, rotating speed, current and noise of the vibrating motors are detected in sequence, automatic testing can be completed when performance testing is conducted on the vibrating motors, personnel and testing stations are saved, the working efficiency of the vibrating motors is greatly improved in performance testing, and the misjudgment phenomenon caused by non-in-place pressing during artificial pressing for testing is eliminated.

Description

technical field [0001] The invention relates to the field of vibration motor production equipment, in particular to an automatic testing device for vibration motor production. Background technique [0002] The vibration motor is a brushed DC motor. There is an eccentric wheel on the motor shaft. When the motor rotates, the center point of the eccentric wheel is not on the center of rotation of the motor, so that the motor is in a state of continuous loss of balance. Vibration is caused by inertia. After the production of the vibration motor is completed, its performance is tested, and the products that fail the performance test are rejected. [0003] In the performance testing process of the existing vibration motors, multiple testing stations and personnel are required to manually press the vibration motors to perform performance testing operations. The equipment personnel occupy a lot of space. During the test, one hand needs to press the vibration motor, and the other han...
