Whether the subsequent automotive glass to be treated is lightly dusty or complex stains mixed with oil films, offset and scale can be effectively treated. This fundamentally ensures that the final cleanliness of the glass can reach the same high standard no matter how the initial state of the glass is fluctuated.
The mechanical arm 3 has at least one of a first working mode for grabbing and placing the automobile glass on the storage rack 1 onto the dirt simulation assembly 2 to form reference glass and grabbing and placing the formed reference glass onto the conveying assembly 4, and a second working mode for grabbing and placing the automobile glass on the storage rack 1 directly onto the conveying assembly 4.
