[0028] See also Figure 3 In this embodiment, a telescopic cylinder 304 is provided in the electric control box 300. The telescopic cylinder 304 can drive its movable end 3041 to extend out of the electric control box and abut against the upper end surface of the workpiece to prevent the workpiece 200 from detaching from the positioning base 100. The telescopic cylinder 304 can drive its movable end 3041 to retract into the electric control box to release the restriction on the workpiece; the telescopic cylinder 304 is electrically connected to the main controller, and the main controller controls the telescopic action of the telescopic cylinder 304.
[0029] More specifically, in this embodiment, a sensor 305 is provided in the electric control box 300 to sense whether the workpiece 200 is in place. The sensor 305 is preferably a laser sensor. The laser is emitted from the electric control box 300 to the area on the positioning base 100 where the workpiece 200 is positioned. The sensor 305 is electrically connected to the main controller. When the sensor 305 senses that the workpiece 200 is placed on the positioning base 100, it sends a signal to the main controller, and the main controller controls the telescopic cylinder 304 to move. The movable end 3041 of the telescopic cylinder 304 extends and abuts against the upper surface of the workpiece 200 to limit the workpiece 200. In order to prevent the movable end 3041 of the telescopic cylinder 304 from causing wear on the surface of the workpiece 200, a rubber sleeve is provided on the movable end 3041 for buffering.
