Meanwhile, the control panel 11 controls the linear module 13 to drive the infrared distance sensor 15 to move linearly, so as to detect the whole metal plate, and realize the automatic detection function of the automatic detection tool on the metal plate.

[0033] If the distance data after detection is different from the data of other positions, the control panel 11 receives a signal to control the marker electric push rod 41 to work, and under the action of the marker electric push rod 41, the marker pen 44 is driven to move downward, so that the marker pen 44 is in contact with the sheet metal to automatically mark the sheet metal, which facilitates subsequent leveling processing.
