[0083] The support frame 251 extends in the left-right direction, and the left and right ends of the support frame 251 are respectively mounted on the left rear corner and the right rear corner of the frame 21;

[0084] The second lifting assembly 252 includes a lifting cylinder 2521 and two first guide rods 2522;

[0085] The lifting plate 253 extends in the left-right direction and is located below the support frame 251; the bottom ends of the two first guide rods 2522 are connected to the left and right ends of the lifting plate 253 at intervals; the top ends of the two first guide rods 2522 respectively penetrate the support frame 251 and protrude upward from the top surface of the support frame 251;

[0086] The lifting cylinder 2521 is installed on the top surface of the support frame 251 and is located between the two first guide rods 2522; the output end of the lifting cylinder 2521 extends downward, passes through the support frame 251, and is connected to the front surface of the lifting plate 253;

[0087] The second pushing assembly 255 includes a horizontal pushing cylinder 2551 and two second guide rods 2552;

[0088] The second push plate 254 extends in the left-right direction, and is located in front of the lifting plate 253 and below the support frame 251; the front ends of the two second guide rods 2552 are connected to the second push plate 254 at intervals on the left and right sides; the rear ends of the two second guide rods 2552 respectively penetrate the lifting plate 253 and protrude backwards from the rear plate surface of the lifting plate 253;

[0089] The horizontal push cylinder 2551 is installed on the rear surface of the lifting plate 253 and is located between the two second guide rods 2552; the output end of the horizontal push cylinder 2551 extends forward, passes through the lifting plate 253, and is connected to the rear surface of the second push plate 254;

[0090] The plate surface of the first push plate 241 and the plate surface of the second push plate 254 are perpendicular to each other;

[0091] The second push plate 254 is used to resist the rear surface of the plate to be processed so that the front and rear surfaces of the plate to be processed are positioned.

[0092] After the side positioning of the long side of the plate to be processed is completed, the lifting cylinder 2521 is started, and the lifting plate 253 and the second push plate 254 are driven by the lifting cylinder 2521 to lower along the two first guide rods 2522 and approach the top surface of the grid frame 1, so that the plate surface of the second push plate 254 and the rear end surface of the plate to be processed are at the same horizontal position, and then the horizontal push cylinder 2551 is started, and the second push plate 254 is driven by the horizontal push cylinder 2551 to push forward along the two second guide rods 2552 to the rear end surface of the plate to be processed, and the front end surface of the plate to be processed reaches To the set target position to complete the positioning of the front end face and the rear end face containing the short edge of the plate to be processed, and then shut down the horizontal pushing cylinder 2551, so that the horizontal pushing cylinder 2551 drives the second push plate 254 and the two second guide rods 2552 to retract, and then shut down the lifting cylinder 2521, so that the lifting cylinder 2521 drives the lifting plate 253 and the second push plate 254 to rise along the two first guide rods 2522 and reset, and then the plate to be processed and the grid frame 1 can be lifted together by the lifting mechanism and transported to the processing station to complete the processing of the plate to be processed.

[0093] After completing the positioning of the front end face and the rear end face containing the short sides of the plate to be processed, the lifting plate 253 and the second push plate 254 are reset in time to prevent the lifting plate 253 and the second push plate 254 from obstructing the lifting and taking of the grid frame 1 and the plate to be processed, and to prevent the lifting plate 253 and the second push plate 254 from blocking the next grid frame 1 and the next plate to be processed from entering the positioning operation area.

[0094] During the positioning process, the lifting plate 253 and the second push plate 254 block the next plate to be processed from entering the positioning operation area, thereby preventing the two plates to be processed from colliding and being damaged.

[0095] Furthermore, a positioning pin 26 is installed on the top surface of the frame 21;

[0096] A positioning sleeve 13 is installed on one side of the grid frame 1; the positioning sleeve 13 protrudes outward from the side of the grid frame 1, and the positioning pin 26 and the positioning sleeve 13 are arranged in a one-to-one correspondence;

[0097] The bottom surface of the positioning sleeve 13 is provided with a positioning groove which is recessed upwards;

[0098] The positioning pin 26 is used to extend into the positioning groove of the positioning sleeve 13;

[0099] The horizontal straight line where the vertices of the two positioning pins 26 are located is parallel to the right plate surface of the first positioning plate 12 .

[0100] like Figure 1 , Figure 3 and Figure 6 As shown, when the grid frame 1 is mounted on the top surface of the frame 21 by the lifting mechanism, the two positioning sleeves 13 on one side of the grid frame 1 are firstly made to face the two positioning pins 26 respectively, and the movement of the grid frame 1 is limited by the two positioning pins 26, so as to avoid displacement of the grid frame 1 due to being touched during the positioning process of the plate to be processed, thereby ensuring that the relative position of the plate to be processed and the grid frame 1 during the positioning process will not change due to the displacement of the grid frame 1.

[0101] It should be noted that, since the position of the above frame 21 is fixed, it is only necessary to know the coordinates of the frame 21 and the hoisting mechanism moves to the same position to put down the grid frame 1 each time, so as to complete the positioning of the grid frame 1.

[0102] The grid frame 1 of the prior art has no positioning parts and is not accurately placed manually. If a mobile robot is used for placement, a complex algorithm is required to control the moving trajectory of the grid frame 1 to achieve accurate positioning to ensure that the long side of the grid frame 1 is parallel to the first push plate 241.

[0103] Specifically, the first lifting assembly 232 includes an upper supporting plate 2321, a lower supporting plate 2323 and a plurality of airbags 2322;

[0106] like Figure 1 and Figure 4 As shown, when the mounting frame 231 needs to be raised, the compressed air pump is turned on and the multiple air bags 2322 are inflated at the same time, so that the upper support plate 2321 can lift the mounting frame 231 upward; conversely, when the mounting frame 231 needs to be lowered, the multiple air bags 2322 are exhausted at the same time, and the air bags 2322 compressed by the weight of the mounting frame 231 continue to shrink, causing the upper support plate 2321 to drop, and driving the mounting frame 231 to drop.

[0107] The installation frame 231 is lifted and lowered by inflating and deflating the airbag 2322, which has good stability, can prevent the installation frame 231 from shaking during the lifting process, can prevent the rotating wheel group 221 and the supporting wheel group 243 from shifting during the lifting process, and ensure the positioning accuracy of the plate to be processed.

[0108] Furthermore, the transmission mechanism 22 is configured with a driving assembly 222 and two rotating wheel sets 221;

[0112] like Figure 1 and Figure 4 As shown, the first driving motor 2220 is used to drive the driving wheel 2223, and the driving wheel 2223 and the multiple driven wheels 2222 drive the belt 2221 and the multiple rotating wheels 2211 to rotate synchronously, so that the moving plate to be positioned has better stability.

[0113] Further, the first pushing assembly 242 includes a second driving motor 2420, a transmission rod 2425, two mounting plates 2421, two transmission gears 2423, two pushing rods 2424 and four guide blocks 2422;

[0114] The guide block 2422 is provided with a guide hole 24221, and the guide hole 24221 penetrates the guide block 2422 from left to right; the push rod 2424 extends in the left-right direction, and the bottom of the outer peripheral surface of the push rod 2424 is provided with a plurality of tooth grooves 24241, and the plurality of tooth grooves 24241 are arranged in sequence along the length direction of the push rod 2424;

[0118] The left end of the push rod 2424 passes through the two opposite guide holes 24221 in sequence and is connected to the first push plate 241 ; the transmission gear 2423 meshes with the multiple tooth grooves 24241 at the bottom of the corresponding push rod 2424 .

[0119] like Figure 1 and Figure 5 As shown, the second driving motor 2420 drives the transmission rod 2425 to rotate, and drives the two push rods 2424 to move left and right along the corresponding guide holes 24221 through the two transmission gears 2423, thereby driving the first push plate 241 to move left and right synchronously.

[0120] Preferably, the positioning groove is in a conical shape that is smaller at the top and larger at the bottom;

[0121] The positioning pin 26 is a cone installed vertically, and a semi-sphere 261 is installed on the top of the positioning pin 26.
