Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to an automatic vibration device for microphones. Background Technique

[0002] With the continuous progress of science and technology and the improvement of people's requirements for product quality, vibration testing, as an important product testing method, has gradually been widely applied. Vibration tests are applicable to products in various industrial fields, including but not limited to electronic devices, automotive parts, aerospace, communication equipment, etc. During transportation and use, products are affected by vibration, which may cause internal components to loosen, fall off, and be damaged, thus affecting the reliability and safety of the products. Through vibration tests, the performance of products in a vibration environment can be evaluated and improved to ensure the normal operation of the products.

[0003] The same is true for microphones. After production, vibration tests are required for evaluation. Currently, most of the testing methods use manual methods for product placement and removal, and the vibration frequency is relatively fixed. After repeating such simple labor hundreds of times, the data is not saved, and people are prone to fatigue. During this period, some operators only focus on improving speed while ignoring quality for work efficiency, vibrate the products randomly a few times, or even do not conduct vibration tests at all, posing quality hazards to the products.

[0052] First, the microphone to be detected is transported from Channel 1 on one side through the conveyor belt. After reaching the opening of Channel 1, the transplant module 2 at this position is activated to suck the microphone and place it temporarily on the top of the carrier 74. When three microphones to be detected are accumulated on the top of the carrier 74, the transplant module 1 is activated to grab and place the three microphones on the top of the carrier 74 at one time on the top of the placement table 21. Subsequently, the clamping mechanism clamps the three microphones. After the fixation is completed, the vibration test device 20 is activated to start the vibration test. After the test is completed, the transplant module 1 grabs and places the three microphones on the top of the carrier 74 on the other side at one time, and then the transplant module 2 on this side sucks and places the microphones on the top of the corresponding carrier 74 one by one on the conveyor belt outside Channel 1 on this side.
