The two clamping frames 271 are spaced apart from each other. A clamping cylinder 28 is connected to a clamping frame 271. The two clamping cylinders 28 respectively drive the two clamping frames 271 to move closer to each other to clamp the cardboard.

[0029] In this embodiment, a plurality of second conveying rollers 31 are rotatably connected to the second conveying frame 3. The plurality of second conveying rollers 31 extend along the length direction of the second conveying frame 3. A second drive motor 32 is provided on the second conveying frame 3.

[0032] In this embodiment, a fourth servo motor 35 is provided on the top of the second conveyor frame 3. The fourth servo motor 35 is connected to a drive shaft 351. Both ends of the drive shaft 351 are connected to a second chain. A second chain is connected to a lifting frame 33. A roller 332 is rotatably connected to the lifting frame 33. The roller 332 rolls up and down on the second conveyor frame 3.

[0033] In this embodiment, cardboard trays are stacked sequentially from top to bottom, and these cardboard trays are supported by two support brackets 34.

[0034] In this embodiment, the specific cardboard stacking process is as follows: First, adjust the distance between the two adjustment frames 12 according to the width specifications of the cardboard. In this process, the adjustment frame 12 is pushed to slide on the first conveyor roller 11 until it moves to the set position and the two conveyor belts 121 are activated. Then, the cardboard is placed piece by piece on the first conveyor roller 11 and the cardboard is clamped and conveyed by the two conveyor belts 121 until the cardboard is conveyed to the discharge end of the first conveyor frame 1.

[0035] At this time, the first servo motor 22, the second servo motor 24, and the third servo motor 26 are started respectively. The first servo motor 22 drives the first chain 221 to convey, and the first chain 221 drives the lifting seat 211 and the two clamping frames 271 to move up and down. The second servo motor 24 drives the second screw 241 to rotate, so as to drive the translation seat 231 and the two clamping frames 271 to move left and right. The third servo motor 26 drives the third screw 261 to rotate, so as to drive the sliding seat 251 and the two clamping frames 271 to move back and forth until the two clamping frames 271 move to the discharge end of the first conveying frame 1. Then, the two clamping cylinders 28 are started, and the two clamping cylinders 28 drive the two clamping frames 271 to move closer to each other until the two clamping frames 271 clamp the cardboard together. Then, the first servo motor 22, the second servo motor 24, and the third servo motor 26 are controlled to transfer the cardboard to the cardboard tray on the second conveying roller 31 for stacking.

[0036] Once the cardboard tray is stacked, the fourth servo motor 35 is activated. The fourth servo motor 35 drives the transmission shaft 351 to rotate, thereby driving the second chain conveyor. This causes the two lifting seats 33, the two support frames 34, and the cardboard tray stack to move up and down until the cardboard tray at the bottom falls onto the second conveyor roller 31. Then, the fourth servo motor 35 is stopped, and the third drive motor 341 is activated. The third drive motor 341 drives the transmission wheel 342 to rotate, cooperating with the slider 343 in the sliding groove 331, causing the support frame 34 to move outward, so that the support frame 34 leaves the cardboard tray at the bottom. Then, the fourth servo motor 35 is controlled to move the two support frames 34 to the cardboard tray above the bottom cardboard tray. Finally, the third drive motor 341 is controlled to drive the two support frames 34 to jointly support the cardboard tray above the bottom cardboard tray.

[0037] At this time, the second drive motor 32 is started, which drives multiple second conveyor rollers 31 to rotate, so as to move the unloaded cardboard tray to the set position, so that the transfer robot can transfer and stack the cardboard.
