Description

Automatic acoustic test box of assembly line
Technical Field
The invention relates to a sound insulation device which can provide low background noise and is applied to a production line for automatic acoustic testing.
Background
Acoustic testing generally requires providing a test environment with low background noise to meet the signal-to-noise ratio required for acoustic testing. The most ideal environment for acoustic testing is typically a professional acoustic laboratory, such as an anechoic or reverberation room. However, because the construction cost of the professional acoustic laboratory is too high and the occupied area is too large, the test demander often does not have the condition for constructing the professional acoustic laboratory.
The acoustic test box is a substitute product of a professional acoustic laboratory, and can achieve the effect similar to that of the professional acoustic laboratory through reasonable sound insulation and sound absorption treatment. The traditional acoustic test box usually needs testers to manually put in and take out equipment to be tested and manually open and close a box door, so that the test time is too long, and the requirement of large-batch acoustic tests cannot be met. Particularly, for acoustic tests on various production lines, high sound insulation and automatic tests need to be simultaneously met, and higher requirements are provided for sound insulation treatment of the test box.
In conclusion, the existing test box cannot simultaneously realize higher sound insulation and pipeline automatic acoustic test.

the two silencing channels are arranged on two side surfaces of the sound insulation box body and are opposite to the door opening of the automatic opening and closing door;
the monitoring camera is arranged on the silencing channel;
the conveying belt is positioned in the box body of the sound insulation box and the sound attenuation channel and can convey equipment to be subjected to acoustic testing;
the inner surface of the sound insulation box body adopts a phononic crystal sound absorption structure, and a corresponding local coupling resonant cavity can be selected according to the frequency characteristic of noise to be reduced, so that the noise reduction effect is improved;
the noise elimination channel is constructed by using a phononic crystal, and a corresponding local coupling resonant cavity can be selected according to the frequency characteristic of noise to be reduced, so that the noise reduction effect is improved;
the monitoring camera is used for monitoring equipment to be subjected to acoustic testing on the upstream of the assembly line. The monitoring camera can control the opening and closing of the automatic opening and closing door through a circuit, and can control the running and the stopping of the conveyor belt;
the automatic opening and closing door can be controlled to be opened and closed by an electric door shaft, and the automatic opening and closing door can be opened at 90 degrees to the maximum extent;
before the equipment to be tested enters the sound insulation box body, the automatic opening and closing door is in an opening state, the conveyor belt is in a running state, after the equipment to be tested enters the sound insulation box body, the automatic opening and closing door is closed, and the conveyor belt is in a pause running state. After the test is finished, the automatic opening and closing door is opened, the conveyor belt runs, and the equipment to be tested is sent out;
the effect is illustrated as follows: the noise reduction amount of the equipment to be tested in and out of the channel is improved through the noise elimination and reduction of the noise elimination channel and the sound insulation and noise reduction of the automatic opening and closing door; the sound absorption is realized through the phononic crystal structure of the sound insulation box body, so that the noise reduction of the box body is improved; in conclusion, the invention aims of high sound insulation and streamline automatic acoustic testing are achieved at the same time.
