At the same time, the fixed plate 105 moves downward along the direction of the telescopic rod 104 due to gravity, so that the two electromagnets 103 come into contact with the plate, and then the two electromagnets 103 are started. The electromagnets 103 adsorb the plate, and then the first self-locking cylinder 101 is started, and the piston end of the first self-locking cylinder 101 contracts, pulling the pull rope 107, and the pull rope 107 drives the fixed plate 105 to move upward, and the fixed plate 105 drives the plate to move upward through two electromagnets 103. A slot 7 is provided at the top of the bottom plate 8 and at the bottom of the loading and unloading assembly 1.

Both sides of the connecting plate 10 are provided with clamping assemblies 3 for fixing the plate, and the two clamping assemblies 3 are respectively arranged at the bottom of the laser cutting machine 2 and the loading and unloading assembly 1. A driving assembly 5 for driving the rotating shaft 11 to rotate is provided on the top of the bottom plate 8.

[0041] In particular, in the present invention, the clamping assembly 3 includes a frame 301 fixed to one side of the connecting plate 10 by bolts, two slide rails 303 are symmetrically arranged on the top of the frame 301, and the tops of the two slide rails 303 are symmetrically connected to two clamping plates 304 slidably connected through a slide, and a plurality of protrusions 305 are fixed to one side of the clamping plate 304 by bolts, and a two-way self-locking cylinder 302 fixedly connected to the frame 301 is provided on one side of the slide rail 303, and the two piston ends of the two-way self-locking cylinder 302 are respectively fixed to the two clamping plates 304, and a clamping assembly 6 for secondary fixing of the plate is provided on the top of one of the clamping plates 304, and the clamping assembly 6 includes two second fixing frames 602 fixed to the top of the clamping plates 304 by bolts and symmetrically arranged, and the top of the second fixing frame 602 The third self-locking cylinder 601 is fixed by bolts, and the piston end of the third self-locking cylinder 601 passes through the second fixing frame 602 and is fixed with a pressure plate 603 by bolts. The third self-locking cylinder 601 is started, and the piston end of the third self-locking cylinder 601 extends to drive the pressure plate 603 to contact the plate and form an extrusion state, thereby realizing secondary fixation of the plate, so that the plate will not shake during the cutting process. The top of the base plate 8 is provided with a plurality of support components 4 for auxiliary support of the frame 301. Two adjacent support components 4 are in contact with the frame 301. The support component 4 includes a first fixing frame 402 fixed to the top of the base plate 8 by bolts. The top of the first fixing frame 402 is provided with a plurality of evenly distributed grooves, and a plurality of grooves are rotatably connected to the frame 301 in the grooves. The contacting balls 401 greatly reduce the friction between the first fixing frame 402 and the frame 301 through the balls 401. The first fixing frame 402 supports the frame 301 so that the frame 301 will not be deformed due to gravity, thereby greatly improving the service life of the device. The two-way self-locking cylinder 302 is started, and the two piston ends of the two two-way self-locking cylinders 302 contract and simultaneously drive the two clamping plates 304 to move inwardly, so that the two clamping plates 304 contact the plate and form an extrusion state, thereby clamping the plate. At the same time, the plate is supported by multiple protrusions 305, thereby greatly improving the stability of clamping the plate.

The moving distance of the fixing frame 902 is limited by the first baffle 901 and the second baffle 903, thereby limiting the moving distance of the rack 502, so that when the fixing frame 902 contacts the first baffle 901 or the second baffle 903, the connecting plate 10 is always at the same angle.To ensure that the connecting plate 10 rotates 180 degrees each time, the second self-locking cylinder 503 is activated. The piston end of the second self-locking cylinder 503 extends, driving the rack 502 to slide to the left. The rack 502 drives the gear 501 to rotate clockwise, and the gear 501 drives the shaft 11 to rotate 180 degrees.

[0042] It should be noted that the first self-locking cylinder 101, the second self-locking cylinder 503, the third self-locking cylinder 601, the two-way self-locking cylinder 302, the electromagnet 103, etc. are existing technologies, and those skilled in the art can set them according to actual needs, which will not be described here.

[0045] S1: The plate is moved to the position of the slot 7 using a cart, and then the first self-locking cylinder 101 is activated. The piston end of the first self-locking cylinder 101 extends, and at the same time, the fixed plate 105 moves downward along the direction of the telescopic rod 104 due to gravity, so that the two electromagnets 103 come into contact with the plate, and then the two electromagnets 103 are activated. The electromagnets 103 adsorb the plate, and then the first self-locking cylinder 101 is activated. The piston end of the first self-locking cylinder 101 contracts, pulling the pull rope 107. The pull rope 107 drives the fixed plate 105 to move upward. The fixed plate 105 drives the plate upward through the two electromagnets 103, and the plate is lifted to the middle position of one of the frames 301;

[0046] S2: Then the two-way self-locking cylinder 302 is started.

At the same time, the plate is supported by the multiple protrusions 305. After clamping, the two electromagnets 103 are turned off, so that the electromagnets 103 are separated from the plate;

[0047] S3: Then, the two third self-locking cylinders 601 on the top of the clamping plate 304 on one of the frames 301 are activated.

[0049] S5: Then start the laser cutting machine 2 to cut the plate. While cutting, start the first self-locking cylinder 101 again. The piston end of the first self-locking cylinder 101 extends. At the same time, the fixed plate 105 moves downward along the direction of the telescopic rod 104 due to gravity, so that the two electromagnets 103 come into contact with the plate. Then start the two electromagnets 103. The electromagnets 103 adsorb the plate. Then start the first self-locking cylinder 101. The piston end of the first self-locking cylinder 101 contracts, pulling the pull rope 107. The pull rope 107 drives the fixed plate 105 to move upward. The fixed plate 105 drives the plate upward through the two electromagnets 103, and the plate is lifted to the middle position of the other frame 301.

[0050] S6: Then the two-way self-locking cylinder 302 is started, and the two piston ends of the two two-way self-locking cylinders 302 contract and simultaneously drive the two clamping plates 304 to move inwards toward each other, so that the two clamping plates 304 contact the plate and form a squeeze state, thereby clamping the plate. At the same time, the plate is supported by multiple protrusions 305. After clamping, the two electromagnets 103 are turned off, so that the electromagnets 103 are separated from the plate. The plate cutting at the bottom of the laser cutting machine 2 is completed;

[0051] S7: Then, the two third self-locking cylinders 601 on the top of the clamping plate 304 on the other frame 301 are activated. The piston ends of the two third self-locking cylinders 601 extend to drive the two pressing plates 603 to contact the plate, thereby forming an extrusion state.

[0052] S8: Start the second self-locking cylinder 503. The piston end of the second self-locking cylinder 503 contracts, driving the rack 502 to slide to the right. The rack 502 drives the counterclockwise gear 501 to rotate. The gear 501 drives the connecting plate 10 through the rotating shaft 11. The connecting plate 10 drives the two frames 301 to rotate 180 degrees counterclockwise at the same time, and the other frame 301 holding the plate is rotated to the bottom of the laser cutting machine 2. At the same time, the cut plate is rotated to the bottom of the electromagnet 103, and then the laser cutting machine 2 is started to cut the plate.

[0053] S9, while cutting, the electromagnets 103 are activated, and the two electromagnets 103 are attracted to the cut plate, and then the piston ends of the third self-locking cylinder 601 and the two third self-locking cylinders 601 extend and respectively drive the two pressing plates 603 to fall out of contact with the plate;

[0054] S10: Then start the two-way self-locking cylinder 302, the two piston ends of the two two-way self-locking cylinders 302 extend and at the same time drive the two clamps 304 to move outwards toward each other, so that the two clamps 304 fall off and contact with the plate, so that the cut plate is released from the fixation, and then the first self-locking cylinder 101, the piston end of the first self-locking cylinder 101 extends, and at the same time the fixed plate 105 moves downward along the direction of the telescopic rod 104 due to gravity, and the plate falls onto the cart, and then the electromagnet 103 is turned off, and this reciprocating cycle is repeated.
