[0088] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0090] Specifically, the square plate input device 100 is used to input the square plate to be cut; the rear conveyor line 200 is located on the left side of the square plate input device 100; the first gantry robot 300 is straddling the square plate input device 100 and the rear conveyor line 200, used to grab the square plate from the square plate input device 100 and move it onto the rear conveyor line 200; the receiving device 400 is located on the rear side of the rear conveyor line 200, used to receive the square plate output by the rear conveyor line 200; the lateral movement device 500 is located on the rear side of the receiving device 400, used to move the square plate located on the receiving device 400 left and right; the corner cutting device 600 is located on the left side of the rear conveyor line 200, and it is connected to the square plate input device 100.

[0091] When the stacked square plates to be cut are placed on the square plate input device 100 and moved backward to the underside of the first gantry robot 300, the first gantry robot 300 grabs the square plates to be cut downward and transports them to the rear conveyor line 200, which then transports them to the receiving device 400. Subsequently, the lateral movement device 500 moves the square plates to be cut left and right on the receiving device 400, and cooperates with the toggle mechanism 700 and the corner cutting device 600 to complete the cutting of the four corners of the square plates. Then, the cut square plates are received by the front guide conveyor line 800 and transported forward to the working area of ​​the second gantry robot 1000. The second gantry robot 1000 grabs the cut square plates downward and transports them to the square plate output device 900, thus completing the automated operation of the entire square plate corner cutting process.

[0092] This application achieves a high degree of automation in the square plate corner shearing operation, significantly improving production efficiency and corner shearing stability. Furthermore, through modular design, each functional unit can be maintained and upgraded independently, significantly reducing equipment downtime and maintenance costs.

[0109] Furthermore, the lateral movement device 500 includes a lateral support 51, a movable connecting seat 52, a lateral movement drive mechanism 53, a left telescopic limit group 54, and a right telescopic limit group 55.

[0110] The movable connecting seat 52 is slidably connected to the upper side of the cross-bracing 51. The lateral movement drive mechanism 53 is located between the cross-bracing 51 and the movable connecting seat 52, and is used to drive the movable connecting seat 52 to move left and right. The lateral movement drive mechanism 53 mainly includes a rack, a drive motor, and a gear.

The left telescopic limit group 54 is located on the left side of the movable connecting seat 52, and its front end can extend and retract forward and backward. The right telescopic limit group 55 is located on the right side of the movable connecting seat 52, and its front end can extend and retract forward and backward. Both the left telescopic limit group 54 and the right telescopic limit group 55 can preferably be composed of a cylinder and guide rods located on both sides of the cylinder to satisfy the function of front and rear telescopic limit.

[0111] Furthermore, the actuating mechanism 700 includes a hinged actuating arm 71 and an actuating drive assembly 72.

The actuating drive assembly 72 is preferably a cylinder, and its right end is connected to the right side of the transverse support 41, and its left end is hinged to the left-lower extension 711. The hinge point between the hinged actuating arm 71 and the transverse support 41 is located between the left-lower extension 711 and the right transverse portion 712.

[0112] When the toggle drive assembly 72 drives the lower left extension 711 to rotate to the right, the right transverse part 712 rotates to the upper left to toggle the square plate located in the transverse groove 4101 to the left; otherwise, the hinged toggle arm 71 is reset.

[0113] Furthermore, the rear transmission line 200 includes a rear transmission line body 21, a tilting platform 22, a tilting drive group 23, a lowering barrier 24, and a lowering switch drive group 25.

The lowering switch drive group 25 is preferably a cylinder, located on the tilting platform 22, and connected to the lowering barrier 24, for driving the lowering barrier 24 to extend and retract.

[0115] When the flipping platform 22, which is in a horizontal position and carries a square plate, is driven by the flipping drive group 23 to flip backward by 72°, the lowering switch drive group 25 drives the lowering barrier 24 to retract, so that the lowering barrier 24 releases the obstruction of the square plate, and then the square plate can tilt and slide into the transverse groove 4101.

[0116] Furthermore, the transverse support 41 includes a front connecting plate 411, a rear connecting plate 412, a bottom support block 413, a connecting column 414, and a connecting fastening plate 415.

[0117] The rear connecting plate 412 is located behind the front connecting plate 411, and its upper side is higher than that of the front connecting plate 411. This ensures that the front opening of the transverse groove 4101 is upward, thereby guiding the square plate to slide smoothly into the transverse groove 4101 and preventing it from slid out. Multiple bottom support blocks 413 are spaced apart between the lower sides of the front connecting plate 411 and the rear connecting plate 412. The purpose of using multiple spaced bottom support blocks 413 is to meet the space requirements. The connecting column 414 connects to the right side of the front connecting plate 411 and the rear connecting plate 412; it mainly serves as a connecting support. The connecting fastening plate 415 is located on the right side of the longitudinal mounting box 62 and is connected to the front connecting plate 411 and the rear connecting plate 412, used to support and fasten the front connecting plate 411 and the rear connecting plate 412.

[0119] Furthermore, the upper left side of the front transverse connecting bracket 82 has a vertically extending and horizontally arranged upper left through groove 821, and the upper right side has a vertically extending and horizontally arranged upper right through groove 822.
