[0044] Through the above technical solution, the structure and function of the grabbing assembly are further improved, and the other two sides of the plate 210 can be aligned. When the grabbing assembly grabs the plate 210 and moves it onto the carrier plate 180, the second hydraulic cylinder 280 drives the mobile frame 290 to descend, and finally the pallet 560 abuts against the upper surface of the plate 210 stacked on the transfer frame 190 and located on the top layer (assuming that other plates 210 are already stacked and stacked on the transfer frame 190 at this time); at this time, the plate 210 to be stacked is separated from the plate 210 stacked on the transfer frame 190 and located on the top layer by only the pallet 560; then the first driving component drives the first connecting arm 470 and the second connecting arm 480 to approach each other, so that the two gear vertical plates 550 connected to the first connecting arm 470 abut against each other. One side of all the plates 210 is connected to, and the two shifting vertical plates 550 connected to the second connecting arm 480 abut against the other side of all the plates 210; then all the second driving components are started simultaneously to drive the pallet 560 to translate in a direction away from the plates 210, so that the pallet 560 is pulled out between the plates 210, thereby stacking the topmost plates 210 on top of the other plates 210 to complete the stacking of the plates 210, and in this stacking process, the shifting vertical plates 550 connected to the first connecting arm 470 and the shifting vertical plates 550 connected to the second connecting arm 480 limit the plates 210 on both sides, thereby ensuring that the plates 210 are aligned.

[0045] In addition, the alignment assembly further includes a slide rail 660, a slider 670, a third support plate 680, a fourth support plate 690, a sixth screw rod 710, a third rotating shaft 720, a third motor 730, a third gear 740, a fourth gear 750 and a limiting component; the slide rail 660 is disposed on the base 130; the extension direction of the slide rail 660 is perpendicular to the abutment plate 170; the slider 670 is slidably connected to the slide rail 660; the abutment plate 170 is connected to a side of the slider 670 close to the bearing plate 180; the third support plate 680 is vertically connected to the base 130, and The third support plate 680 is located on the side of the slide rail 660 away from the bearing plate 180; the fourth support plate 690 is connected to the slider 670, and the fourth support plate 690 is located between the third support plate 680 and the abutment plate 170; the third support plate 680 and the fourth support plate 690 are both parallel to the abutment plate 170; the limiting component includes a limiting baffle 780 for abutting against the lower part of the abutment plate 170, and a contact switch (unnumbered) is provided on the side of the limiting baffle 780 close to the abutment plate 170; the limiting baffle 780 is located between the abutment plate 170 and the second limiting vertical plate 150.

[0047] Through the above technical solution, the structure of the alignment assembly is further improved; whenever a new plate 210 is stacked on the carrier plate 180, the third motor 730 is started to drive the sixth screw rod 710 to rotate, thereby driving the slide rail 660 to translate, thereby driving the plate 170 to move in the direction close to the second limit vertical plate 150, so that the plate 170 abuts against one side of the plate 210 (at this time, the lower part of the plate 170 abuts against the contact switch of the limit baffle 780 and triggers the contact switch. After receiving the signal that the contact switch is triggered, the controller controls the third motor 730 to stop, thereby preventing the plate 170 from excessively moving and damaging the plate 210), and the second limit vertical plate 150 abuts against the other side of the plate 210. In this way, the stacked plates 210 can be aligned by relative clamping. After alignment, the third motor 730 is started again to drive the sixth screw rod 710 to rotate, thereby driving the plate 170 to translate in the direction away from the second limit vertical plate 150, so that the subsequent new plates 210 can be stacked.
