Automatic horn air leakage detection device and horn air leakage automatic detection method

Abstract

The invention relates to an automatic horn air leakage detection device and a horn air leakage automatic detection method. The solenoid valve, the controller is electrically connected with the solenoid valve; the outer wall of the casing is equipped with an alarm, a water level box, and a water level sensor is installed on the water level box; both the water level sensor and the alarm are connected to the controller; the top plate of the casing The lifting cylinder connected with the starting sensor is fixed, and the upper mold connected with the lifting cylinder is arranged under the top plate of the casing; the upper mold has a first accommodating cavity, and the solenoid valve is connected with a gas delivery pipeline and communicates with the first gas delivery pipeline through the gas delivery pipeline. The lower mold has a second accommodation cavity; the water level box is connected to the second accommodation cavity; the horn to be tested is placed above the opening of the second accommodation cavity and sealed by an inner sealing ring. It can automatically and accurately judge the airtightness of each horn, achieve the purpose of automatic detection of air leakage, and reduce labor intensity.

Description

technical field [0001] The invention relates to horn manufacturing equipment, in particular to a horn air leakage automatic detection device and a horn air leakage automatic detection. Background technique [0002] After the horn is glued and dried, the airtightness of the horn needs to be tested to ensure the quality of the horn. The traditional method is to press the speaker by the operator, put one end of the leather tube in the ear hole, and put the other end on the surface of the speaker, and listen to the airflow sound through the ear to determine whether there is air leakage. It takes more than 10 seconds to detect a speaker Time, this is a waste of manpower, and it is easy to make people tired during the operation, and the judgment standard is judged by human consciousness, which is prone to misjudgment. Contents of the invention [0003] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide an automatic speaker a...
