How to realize the automatic edge finding technology of Li Xing laser cutting machine?

Because the plate may be skewed when placed manually on the workbench of the laser cutting machine, when the control system of the laser cutting machine automatically senses the tilt angle and origin of the plate, the control system automatically senses the tilt angle and origin of the plate, and accordingly adjusts the cutting program to adapt to the angle and position of the plate, so as to carry out edge-finding cutting and avoid waste. The principle of automatic edge finding combined with images is simple:

Starting from point P, the laser cutting head will automatically measure three points on two vertical sides of the plate: P 1, P2, P3, and automatically calculate and find out the inclination angle a and the origin of the plate according to this, and then cut.

Therefore, the importance of automatic edge finding technology to laser cutting machine is highlighted. The further development of automatic edge finding technology is that the edge end of the plate is accurately found by capacitance sensor ranging, and the slope of the included angle between the plate and the axis of the machine tool is automatically calculated and memorized by the numerical control system. As long as the worker presses the "find edge" button, the system will automatically rotate the XY axis of the machine tool according to the slope accuracy of the plate during cutting, so as to ensure that the cutting X direction is parallel to the long straight edge direction of the plate.
