10. The working method of the corner cutting equipment for producing and processing the PVC template is characterized by comprising the following steps of:

the method comprises the following steps: an output shaft of a first motor (3) drives a first screw rod (8) to rotate, the first screw rod (8) is matched with a first screw rod nut (7) to drive a translation plate (6) to move, the translation plate (6) moves along a first slide rail (4) on a cross beam (2) through a first slide block (5) at the bottom, then a mounting frame (24) is driven to move to one side far away from a connecting beam (10), and a plurality of PVC templates are stacked on a sucker (37) on a bottom symmetrical plate (33);

step two: the piston rod of the first air cylinder (27) contracts, so that the centering plate (28) at the bottom is driven to ascend through the connecting seat (271), the centering plate (28) at the bottom drives the rotating plate (32) to rotate along the central shaft (322) through the hexagonal pull rod (31), the rotating plate (32) drives the centering plate (28) at the top to descend through the hexagonal pull rod (31) at the other side, the two centering plates (28) move oppositely, the four limiting plates (36) are driven to move oppositely through the symmetrical plates (33), the suckers (37) of the upper limiting plate (36) are in contact with the PVC template at the top, then the piston rod of the second air cylinder (34) pushes the limiting plates (36), the limiting plates (36) drive the telescopic rods (35) to extend, and the suckers (37) on the limiting plates (36) press and fix the PVC template;

step three: the output shaft of the first motor (3) rotates, the two translation plates (6) drive the mounting rack (24) to move towards the connecting beam (10), further moving the stacked PVC templates to the position below the cutting position of the laser cutting head (23), driving a second screw rod (12) to rotate by an output shaft of a second motor (11), driving a mounting plate (14) to move by the second screw rod (12) matching with a second screw rod nut (13) so as to drive the laser cutting head (23) to move, cutting the uppermost PVC template, driving a third screw rod (18) to rotate by an output shaft of a third motor (17), driving a lifting plate (20) to descend by the third screw rod (18) matching with a third screw rod nut (19), driving the lifting plate (20) to descend along a third slide rail (22) on the mounting plate (14) through a third slide block (21), and then the laser cutting head (23) is driven to descend, and the laser cutting head (23) cuts the next PVC template.
