One side of the gripping motor plate is fixedly connected to one side of the connecting plate. The other side of the gripping motor plate is fixedly connected to one side of the connecting shaft. The other side of the connecting shaft is rotatably connected to the gripping telescopic motor.

[0011] Furthermore, the stacking assembly also includes a transfer plate with one end connected to the ear plate pin, and the other end of the transfer plate is fixedly connected to the outer surface of the movable rod through the connecting slot.

The limiting groove 7 communicates with the transmission channel 6. The limiting groove 7 is opened in the connecting frame plate 5. The moving component also includes two telescopic motors 14 fixedly connected to the bottom sides of the connecting plate 11. The extension shaft end of the telescopic motor 14 is fixedly connected to one end of a telescopic rod 12. The other end of the telescopic rod 12 is fixedly connected to the upper surface of the gripping frame 13. Two slide rails 25 are fixedly connected to the lower surfaces of both sides of the gripping frame 13.

[0027] See Figure 4 and Figure 5The stacking assembly includes two dual-axis motors 16, each fixedly connected to the inner walls of the gripping slot 15. The two output ends of each motor 16 are connected to one end of a guide screw 17, with the two guide screws 17 rotating in opposite directions. The other end of the guide screw 17 is rotatably connected to one inner wall of the gripping slot 15. One end of a guide fixing block 18 is threaded onto the outer surface of the guide screw 17. The other end of the guide fixing block 18 is fixed to the connecting plate 24. The stacking assembly also includes two sliders 23, each fixedly connected to both sides of the connecting plate 24. Block 23 is slidably connected to slide rail 25. One side of the surface of connecting plate 24 is fixedly connected to one side of gripping motor plate 30. The other side of gripping motor plate 30 is fixedly connected to one side of connecting shaft 31. The other side of connecting shaft 31 is rotatably connected to gripping telescopic motor 26. The extension shaft end of gripping telescopic motor 26 is connected to one end of gripping telescopic rod 27. The other end of gripping telescopic rod 27 is fixedly connected to one end of ear plate 28. The stacking assembly also includes a transmission plate 32, one end of which is pin-connected to ear plate 28. The other end of transmission plate 32 passes through a through groove. 29 is fixedly connected to the outer surface of the movable rod 33. The connecting slot 29 is opened on the connecting plate 24. A stabilizing plate 39 is fixedly connected to the outer surfaces of both sides of the movable rod 33. The stabilizing plate 39 is fixedly connected to the lower surface of the connecting plate 24. The stacking assembly also includes two gripping auxiliary plates 34, one end of which is fixedly connected to the outer surfaces of both sides of the movable rod 33. The other end of the gripping auxiliary plates 34 is fixedly connected to the fixed plate 35. Several grippers 36 are fixedly connected to the fixed plate 35. An abutment plate 37 is fixedly connected to one side surface of the fixed plate 35. In conjunction with the gripper 36, the stacking assembly also includes an auxiliary telescopic motor 19 fixedly connected to the upper surface of the gripping frame 13. The extension shaft end of the auxiliary telescopic motor 19 is connected to one end of the auxiliary slide rod 21. The other end of the auxiliary slide rod 21 passes through the gripping frame 13 to the gripping slot 15 and is fixedly connected to the auxiliary plate 22. One end of an auxiliary slide rod 21 is fixedly connected to each side of the upper surface of the auxiliary plate 22. The other end of the auxiliary slide rod 21 passes through the gripping slot 15 to the outside of the gripping frame 13. The auxiliary plate 22 cooperates with the abutment plate 37 and the gripper 36.

[0028] When materials need to be clamped, the gripping telescopic motor 26 is started, causing the gripping telescopic rod 27 to pull the ear plate 28 to move outward. Then, the ear plate 28 pulls the transfer plate 32, causing the movable rod 33 to rotate and rotate inward with the movable rod 33 as the axis. When the movable rod 33 moves, it drives the fixed plate 35 to rotate simultaneously through the gripping auxiliary plate 34. When the fixed plate 35 rotates, it grips and clamps the materials through several claws 36 and the abutment plate 37, thus facilitating stacking operations. The auxiliary telescopic motor 19 is started, causing the auxiliary telescopic rod 20 to push the auxiliary plate 22 to move downward. The auxiliary sliding rods limit the auxiliary plate 22, so that the auxiliary plate 22 clamps the materials from above for a second time to prevent them from falling during the stacking process.

[0029] When faced with materials of different sizes, the dual-axis motor 16 is started, causing the guide screws 17 on both sides to drive the two guide fixing blocks 18 to slide in opposite directions. Then, the fixing blocks 18 drive the connecting plate 24 to move outward at the same time. Because of the auxiliary limit between the slider 23 and the slide rail 25, the connecting plate 24 moves smoothly without deviation. When the two connecting plates 24 move away from each other, they drive the two sets of grippers 36 and the abutment plate 37 below to widen the distance between them, thereby clamping larger materials.

[0030] When the stacking assembly needs to be moved, the two telescopic motors 14 are activated to move the two telescopic rods 12 up and down. The second transmission motor 9 is activated to move the connecting plate 11 in the X-axis direction via the screw 10. The auxiliary limit between the limiting plate 8 and the limiting groove 7 prevents the connecting plate 11 from shifting during movement. Thus, the connecting plate 11 moves in the X-axis direction via the two sets of transmission motors 29 and the screw 10. Then, the screw 10 moves the stacking assembly in the X-axis direction. The two transmission motors 38 are activated to rotate the two screws 4. Then, the screws 4 move the frame plate 5 in the Y-axis direction. Then, the frame plate 5 moves the stacking assembly below in the Y-axis direction. This achieves the movement of the stacking assembly in three axes to meet the needs of all-round stacking operations.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
