A non-contact dynamic angular displacement detecting method for detecting the sheet metal structure of household appliance

Aiming at the problem of vibration detection in the factory production line, a dynamic angular displacement detection method based on laser displacement sensor is proposed. This article takes the air conditioner as an example. The dynamic angular displacement detection method is used to detect the dynamic angular displacement of a certain point of the air conditioning external unit. The results show that the test point in the region of the axial fan speed abnormal air conditioning external unit is more violent twist, In the case of axial fan blades installed incorrectly, the twist of the air conditioner is relatively gentle. The dynamic angular displacement test method can effectively detect the fault phenomenon.
