As shown in fig. 5, in this embodiment, an elastic blocking piece 7 is additionally installed on the cylindrical cam 304 during operation, the elastic blocking piece 7 is fixedly installed in the first cam groove 308 and the second cam groove 309, the specific installation position of the elastic blocking piece 7 in the first cam groove 308 and the second cam groove 309 is determined by specific working conditions, and the installation position of the elastic blocking piece 7 depends on the height difference between the stone plate processing equipment and the assembly line conveying equipment.

The working principle is as follows: the operation principle of the suction cup 604 is that compressed air is input into the hose line 606 by an air compressor, and the compressed air flows into the vacuum generator line 608 through the metal hard line 605 and flows out from the other end of the vacuum generator 603, so that the air in the whole suction cup line 607 is pumped out downstream, and a vacuum environment is formed in the suction cup line 607, so that the suction cup 604 sucks the stone plate. Before the device is used, the height of the base module 1 is firstly adjusted through the hydraulic lifter 101 according to the height of the stone processing device, and the height is adjusted to the extent that the sucker 604 in the grabbing module 6 can just and happily completely suck the stone plate surface when the cam column 501 moves downwards to the bottommost part of the first cam groove 308. The elastic stop 7 is then mounted (welded or glued) in the first cam groove 308 and the second cam groove 309 at a suitable height position according to the height of the conveyor belt, so that the lowest end of the gripping module 6 that is sucking the stone slab is slightly higher than the conveyor belt when the cam column 501 moves upwards to the position of the elastic stop 7. When the work starts, the stepping motor 2 drives the cam to rotate counterclockwise, at this time, the cam column 501 and the cam support column 502 have a tendency to move downward in the first cam groove 308 and the second cam groove 309, but because of the spring support in the spring support plate 405, the whole lifting module 5 cannot move downward, at this time, the torque is enough to drive the rotating module 4, so that the device starts to rotate counterclockwise, but because of the existence of the auxiliary rod 103, the rotation is limited, at this time, the stepping motor 2 continues to rotate, after the operation of the rotating module 4 is forced to stop, the cam column 501 and the cam support column 502 start to slide downward in the first cam groove 308 and the second cam groove 309 along two cam groove tracks, the process that the lifting module 5 drives the grabbing module 6 to move downward is completed (the compressor is in the working state in the whole process), when the cam column slides to the bottom end of the first cam groove 308, at this time, the suction cup 604 in the grabbing module 6 is completely pressed, the stone plate is firmly sucked by the suction cup 604. At the moment, the stepping motor 2 starts to rotate reversely, because the friction factor of the first thrust roller bearing 303 is smaller than that of the bottom of the supporting and connecting seat 302, the additional spring is supported upwards, the cam column 501 starts to slide upwards along the first cam groove 308, the lifting module 5 rises, the cam column 501 stops moving when the cam column 501 slides to the position of the elastic retaining sheet 7, the stepping motor 2 continues to rotate, the whole cam starts to drive the lifting module 5, the rotating module 4 and the grabbing module 6 to rotate together under the driving of the torque of the stepping motor 2, the stepping motor 2 stops rotating after rotating to 180 degrees, the air compressor stops supplying air for 1-2 seconds, the sucking disc 604 removes force, the stone plate falls onto the plane of the conveying belt conveyor, the stepping motor 2 starts to rotate backwards to complete the moving process of the stone plate, at the moment, the spring lifting module 5 pushes upwards, the cam column 501 still stays at the original position, the stepping motor 2 drives the rotating module 4 to rotate back to the initial position, and the second grabbing process is started.

For those skilled in the art, based on the teachings of the present invention, changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
