Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading equipment, and in particular to an automatic loading and unloading equipment for testing a vibration motor. Background Art

[0002] Before leaving the factory, micro vibration motors are usually placed in a soundproof shielding box to test noise-related data during the motor vibration process. The soundproof shielding box requires the noise of the external environment to be lower than 55db, so the test is usually carried out in a silent room.

[0003] Chinese patent application CN110899153A discloses an automatic testing device for vibration motor production, including a feeding belt, a feeding belt, a testing jig and an NG box. The automatic testing device realizes the conveying of the vibration motor by the feeding belt and the feeding belt, and drives the vacuum suction nozzle to move by the conveyor belt on the translation frame to realize the transfer operation of the vibration motor, so as to realize the detection of the working noise and other performance of the vibration motor. However, the device still has the following problems:

[0004] 1. The device's conveying equipment and mobile equipment for the vibration motor make the external environmental noise greater than 55db when the vibration motor is tested for noise, affecting the noise test results;

[0005] 2. If a commercially available industrial six-axis or four-axis robot is used for automated loading and unloading, a double-claw structure is usually used, with one claw used to grab the product to be tested and the other claw used to grab the tested product; if the robot meets the production cycle requirements, the noise usually has to reach 80db, which does not meet the noise requirement of less than 55db; if the robot is slowed down to control the noise within 55db, the production cycle will exceed 15S and the test efficiency will be low.
