Furthermore, manual stacking is inefficient, labor-intensive, and prone to human error. To solve these problems, this invention provides a robotic stacking device that can perform stacking operations efficiently and accurately, reducing costs and labor intensity. Utility Model Content

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1 to 7 This utility model provides a robotic palletizing device, characterized in that it includes:

[0030] A pallet support 1 is provided for placing pallets. The pallet support 1 is provided with a pallet outlet 101. The pallet support 1 is provided with a lifting mechanism 2 and a blocking mechanism 3. The lifting mechanism 2 includes a lifting drive device 201 and a support member 202. The lifting drive device 201 is pulsatorically connected to the support member 202. The blocking mechanism 3 is located above the lifting mechanism 2. The blocking mechanism 3 includes a blocking drive device 301 and a blocking member 302. The blocking drive device 301 is pulsatorically connected to the blocking member 302. A first pallet conveyor belt 102 is provided at the lower part of the pallet support 1. The position of the first pallet conveyor belt 102 corresponds to the position of the pallet outlet 101.

[0031] The hopper 4 is used to hold material trays;

[0032] Conveying mechanism 5, the position of the tray outlet 101 corresponds to that of the conveying mechanism 5;

[0033] The robotic arm 6 includes a robotic arm 601 and a gripper mechanism 602. The robotic arm 601 is used to drive the gripper mechanism 602 to move to a first position and a second position. The first position corresponds to the position of the hopper 4, and the second position corresponds to the position of the conveying mechanism 5. The gripper mechanism 602 includes a gripper drive device 603 and a clamping plate 604. The gripper drive device 603 is connected to the clamping plate 604 in a transmission connection.

[0034] This utility model embodiment provides a robotic palletizing device, including a pallet support 1, a hopper, a conveying mechanism 5, and a robotic arm 6. In use, the pallet is first placed in the pallet support 1, and then the material tray is placed in the hopper 4. Initially, the blocking member 302 is located inside the pallet support 1 and abuts against the pallet. The lifting drive device 201 drives the support member 202 to rise, causing the support member 202 to abut against the pallet. Under the action of the blocking drive device 301, the blocking member 302 disengages from the pallet. The lifting drive device 201 then drives the support member 202 to descend. When the support member 202 descends to the point where the bottom of the second-to-last pallet is flush with the blocking member 302, the support member 202 stops descending. The blocking member 302 extends and abuts against the second-to-last pallet, serving to support it. The supporting member 202 continues to descend, allowing the bottom pallet to be placed stably on the first pallet conveyor belt 102. The first pallet conveyor belt 102 transports the pallet to the conveying mechanism 5. The robotic arm 6 grasps the pallet using the gripper mechanism 602 and places it on the pallet. The length of the clamping plate 604 matches the length of the seedlings and saplings to ensure stable clamping and prevent damage to the seedlings during clamping. When the pallet is filled with a layer of pallets, the conveying mechanism 5 moves the pallet to a designated position to complete the stacking operation, ensuring that the entire process is efficient and precise, improving production efficiency, and reducing costs and labor intensity.

[0035] In a further embodiment of this invention, the gripper mechanism 602 further includes a connecting plate 605, which is connected to the robotic arm 601. The gripper drive device 603 is disposed on the connecting plate 605. There are two grippers 604, which are distributed at both ends of the connecting plate 605.

[0036] In this embodiment, the gripper driving device 603 is a gripper driving cylinder. There are two gripper plates 604, which are distributed at both ends of the connecting plate 605. There are also two gripper driving cylinders, which are respectively connected to the two gripper plates 604. The two gripper plates 604 are respectively installed at both ends of the connecting plate 605. Through the synchronous action of the two gripper driving cylinders, the opening and closing of the gripper plates 604 are consistent, and the clamping force is evenly distributed, effectively preventing the material tray from tilting or slipping during transportation, and further improving the stability and safety of stacking.

[0037] In a further embodiment of this invention, a stop 606 is provided at the lower part of the clamping plate 604.

[0038] In this embodiment, the lower part of the clamping plate 604 is provided with a stop 606. The stop 606 contacts the bottom of the material tray to prevent the material tray from moving during the clamping process, increase the clamping stability, ensure that the material tray remains horizontal during the handling process, reduce the damage to the material tray caused by shaking, further optimize the palletizing effect, and improve the reliability and safety of the overall operation.

[0039] In a further embodiment of this invention, the lifting mechanism 2 further includes a plurality of lifting guide rods 203, which are distributed around the lifting drive device 201. One end of each lifting guide rod 203 is connected to the support member 202, and the other end of each lifting guide rod 203 is connected to the tray bracket 1.

[0040] In this embodiment, the lifting mechanism 2 further includes a plurality of lifting guide rods 203, which are distributed around the lifting drive device 201. When the lifting drive device 201 drives the support member 202 to rise or fall, the lifting guide rods 203 extend and retract synchronously to ensure that the support member 202 rises and falls smoothly, avoids pallet displacement caused by tilting, and further ensures safe and efficient operation.

[0041] In a further embodiment of this invention, the lifting drive device 201 is a lifting drive motor, which is used to drive the support member 202 to lift and lower. The lifting drive motor is located below the first pallet conveyor belt 102.

[0042] In this embodiment, since the support member 202 needs to stop midway and wait for the blocking member 302 to extend and support the penultimate pallet during the descent of the pallet, a lifting drive motor is used as the lifting drive device 201. The lifting drive motor has a precise speed adjustment function to ensure that the support member 202 is stable and impact-free when stopping and starting, effectively avoiding pallet swaying due to inertia, improving operation accuracy and safety, and ensuring the smoothness and stability of the entire palletizing process.

[0043] In a further embodiment of this invention, the blocking member 302 includes a connecting arm 303 and a blocking arm 304. A hinge portion 305 is provided between the connecting arm 303 and the blocking arm 304. The hinge portion 305 is rotatably connected to a hinge member provided on the side wall of the tray support 1. The connecting arm 303 is drively connected to the blocking drive device 301. The blocking drive device 301 is used to drive the blocking member 302 to rotate to a first preset position and a second preset position. When the blocking member 302 is located in the first preset position, the blocking arm 304 extends into the storage space of the tray support 1. When the blocking member 302 is located in the second preset position, the blocking arm 304 disengages from the storage space of the tray support 1. The storage space is used to store a tray.

[0044] In this embodiment, the blocking drive device 301 is a blocking drive cylinder. The blocking drive cylinder drives the blocking member 302 to rotate to a first preset position and a second preset position by extending and retracting. Since the blocking support arm 304 moves by rotation rather than linear movement, the extension and retraction direction of the blocking drive cylinder does not need to be directly opposite the storage space of the tray support 1. This allows for flexible arrangement, saves space, and improves equipment utilization. The length of the blocking support arm 304 is greater than the length of the connecting support arm 303. This ensures that the blocking support arm 304 has sufficient support area to stabilize the tray when it extends into the storage space, while also reducing the extension and retraction stroke of the blocking drive cylinder, further saving space and improving equipment utilization.

[0045] In a further embodiment of this invention, a hopper conveyor belt 401 is provided on the hopper 4.

[0046] In this embodiment, a material hopper 4 is provided with a material hopper conveyor belt 401. The material hopper 4 conveyor belt is used to move the material tray to a suitable position so that the robotic arm 6 can grab the material tray, ensure continuous material transmission, reduce manual intervention, improve the degree of automation of operation, further optimize the production process, reduce the operation error rate, and enhance the overall operation efficiency and stability.

[0047] In a further embodiment of this invention, the conveying mechanism 5 is provided with a conveying frame 501 and a plurality of conveying rollers 502, and the plurality of conveying rollers 502 are evenly distributed on the conveying frame 501.

[0048] In this embodiment, the conveying mechanism 5 is provided with a conveying frame 501 and a plurality of conveying rollers 502. Through the coordinated rotation of the plurality of conveying rollers 502, the pallet is transported smoothly. The conveying frame 501 provides stable support and ensures that the conveying rollers 502 operate synchronously, avoiding the pallet from shifting during the transport process. This can prevent the pallet placed on the pallet from slipping or being damaged due to unstable transport, thereby improving the safety and stability of the pallet during the transport process.

[0049] In a further embodiment of this invention, the conveying mechanism 5 is provided with a second pallet conveyor belt 503 and a conveyor belt lifting device 504. The position of the second pallet conveyor belt 503 corresponds to the position of the first pallet conveyor belt 102. The second pallet conveyor belt 503 is located between the two conveyor rollers 502. The conveyor belt lifting device 504 is used to drive the second pallet conveyor belt 503 to move to a third preset position and a fourth preset position. When the second pallet conveyor belt 503 is located at the third preset position, the second pallet conveyor belt 503 is located above the conveyor rollers 502. When the second pallet conveyor belt 503 is located at the fourth preset position, the second pallet conveyor belt 503 is located below the conveyor rollers 502.

[0050] In this embodiment, the conveying mechanism 5 is equipped with a second pallet conveyor belt 503 and a conveyor belt lifting device 504. The conveyor belt lifting device 504 is a conveyor belt lifting cylinder, which can precisely control the height of the second pallet conveyor belt 503. Initially, the second pallet conveyor belt 503 is located at a third preset position. When the first pallet conveyor belt 102 transmits the pallet from the pallet outlet 101 and enters above the conveyor roller 502, the pallet is smoothly received. Subsequently, the conveyor belt lifting cylinder actuates, lowering the second pallet conveyor belt 503 to a fourth preset position, allowing the pallet to fall smoothly onto the conveyor roller 502, ensuring a smooth transition. After the pallet falls smoothly onto the conveyor roller 502, and the conveyor roller 502 transfers the pallet to the palletizing station, the conveyor belt lifting cylinder actuates again, raising the second pallet conveyor belt 503 back to the third preset position, ready to receive the next pallet. By setting up the second pallet conveyor belt 503 and the conveyor belt lifting device 504, the pallet transfer process becomes smoother and more stable, reducing the failure rate and achieving seamless connection of the production process, which greatly improves the overall operating efficiency of the production line.

[0051] In a further embodiment of this invention, the conveying mechanism 5 is provided with a lifting baffle 505 and a baffle driving device 506. The lifting baffle 505 is located between the two conveying rollers 502. The baffle driving device 506 is used to drive the lifting baffle 505 to move to a fifth preset position and a sixth preset position. When the lifting baffle 505 is located at the fifth preset position, the lifting baffle 505 is located above the conveying roller 502. When the lifting baffle 505 is located at the sixth preset position, the lifting baffle 505 is located below the conveying roller 502.

[0052] In this embodiment, the conveying mechanism 5 is equipped with a lifting baffle 505 and a baffle driving device 506. Initially, the lifting baffle 505 is located at the fifth preset position. The pallet, transferred from the pallet support 1 to the conveying mechanism 5, is driven by the conveying roller 502 and conveyed along the conveyor frame 501 to the palletizing station. When the pallet comes into contact with the lifting baffle 505, indicating that the pallet has reached the designated position, the robotic arm 6 places the material tray onto the pallet. Once the pallet is filled with one layer of material trays, the baffle driving device 506 activates, lowering the lifting baffle 505 to the sixth preset position, allowing the pallet to smoothly slide to the next process. After the pallet leaves the palletizing station, the lifting baffle 505 is immediately raised to the fifth preset position, ready to receive a new pallet. This process repeats, and the precise control of the lifting baffle 505 ensures that the pallet accurately reaches the designated position and that the material tray is accurately and stably placed on the pallet, preventing the material tray from falling or being damaged during transfer and ensuring the smooth operation of the production process.
