<p>A glass-wiping device comprises a machine body (1) and a control unit. The machine body (1) is provided with an edge detection unit (100), the edge detection unit (100) comprises a sensor switch (101, 101') and an action element (102). The action element (102) is provided at a lower end thereof with a contact leg (1021, 1021') that presses against the surface of a glass (200). When the contact leg (1021, 1021') leaves the surface of the glass (200), the action element (102) correspondingly generates a displacement and triggers the sensor switch (101, 101'); the sensor switch (101, 101') transmits a switch signal to the control unit; the control unit controls, on the basis of the switch signal, the glass-wiping device to cease running or to change the running direction. The glass-wiping device has a simple structure, reduced costs, high sensitivity and great controllability, and effectively implements the detection of the edge of a plate glass.</p> |
