[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figures 1 - 10As shown in the figure, a modular designed robotic palletizing workstation provided by the present invention includes a working platform 1, on which a self-feeding pallet library 2, a pallet transfer mechanism 3, a palletizing robot 4 and a feeding conveyor line 5 are fixedly installed. The pallet transfer mechanism 3 includes a push plate mechanism 6, a pallet temporary storage table 7, a palletizing table 8 and a blanking table 9. The palletizing robot 4 includes a lifting structure 10, a multi-axis robotic arm 11 and an adsorption assembly 12. The lifting structure 10 fixedly installs the multi-axis robotic arm 11, and the multi-axis robotic arm 11 fixedly installs the adsorption assembly 12. The lifting structure 10 includes a first fixed frame 13, a lifting frame 14 and a driving device 15. The first fixed frame 13 is movably connected to the lifting frame 14 through a slide rail 16, the driving device 15 is drivingly connected to the lifting frame 14, and the lifting frame 14 fixedly installs the multi-axis robotic arm 11. The adsorption assembly 12 is provided with a plurality of suction cups 17. The push plate mechanism 6 includes a bracket 18, a first driving motor 19 and a push rod assembly 20. The bracket 18 movably installs the push rod assembly 20 through a smooth shaft 21. The bracket 18 is provided with a movable wheel 22. The first driving motor 19 is drivingly connected to the movable wheel 22 through a belt 23, and the belt 23 is fixedly connected to the push rod assembly 20. The pallet temporary storage table 7 and the palletizing table 8 are of the same structure, and both include a second fixed frame 24, a second driving motor 25 and a plurality of second roller shafts 26. The second fixed frame 24 movably installs the second roller shafts 26, and the second driving motor 25 is drivingly connected to the second roller shafts 26. The blanking table 9 includes a third fixed frame 27, a third driving motor 28 and a plurality of third roller shafts 29. The third fixed frame 27 movably installs the third roller shafts 29, and the third driving motor 28 is drivingly connected to the third roller shafts 29. The blanking table 9 is provided with a fork material port 30. A slide plate 31 is arranged between the pallet temporary storage table 7 and the palletizing table 8. The periphery of the working platform 1 is fixedly installed with a protective net 32. A control console 33 is placed beside the working platform 1.

[0031] Through the above technical solution, the present invention is based on the assembly of the working platform 1. On the working platform 1, a self-feeding pallet library 2, a pallet transfer mechanism 3, a palletizing robot 4 and a feeding conveyor line 5 are fixedly installed. By disassembling the self-feeding pallet library 2, the pallet transfer mechanism 3, the palletizing robot 4 and the feeding conveyor line 5 on the working platform 1, the disassembly process can be quickly completed. In this process, there is no need to disassemble each mechanism into scattered parts, reducing the disassembly and installation steps and the debugging process during later assembly, and improving the disassembly and assembly efficiency.

[0032] The pallet transfer mechanism 3 of the present invention includes a push plate mechanism 6, a pallet temporary storage table 7, a palletizing table 8 and a blanking table 9. When in the transfer position, the pallet transfer mechanism 3 is relatively large in volume. By disassembling the pallet transfer mechanism 3 into the push plate mechanism 6, the pallet temporary storage table 7, the palletizing table 8 and the blanking table 9, it is convenient for handling.

[0033] Embodiment 2:

[0034] As Figures 1 - 10As shown in the figure, the working platform 1 of the present invention is the basic structure of the entire system. Four main functional modules are fixedly installed on the working platform 1: the self-feeding pallet library 2, the pallet transfer mechanism 3, the palletizing manipulator 4, and the feeding conveyor line 5.

[0035] The self-feeding pallet library 2 is located on one side of the workstation and is responsible for storing and automatically conveying empty pallets. It includes a pallet storage area and a set of conveying mechanisms, which can send pallets into the system as needed. The pallet transfer mechanism 3 consists of four sub-modules: the push plate mechanism 6, the pallet temporary storage table 7, the palletizing table 8, and the discharging table 9. The push plate mechanism 6 is installed on one side of the pallet temporary storage table 7 and the palletizing table 8, and is used to push the pallet from the pallet temporary storage table 7 to the palletizing table 8. The pallet temporary storage table 7 is located at the exit of the self-feeding pallet library 2 and is used to temporarily store pallets to be used. The palletizing table 8 is located beside the pallet temporary storage table 7 and is the platform for actual palletizing operations. The discharging table 9 is located beside the palletizing table 8 and is used to place the palletized pallets.

[0036] The feeding conveyor line 5 extends into the workstation and conveys the goods to be palletized into the system. The palletizing manipulator 4 is installed on the workstation and can cover the entire palletizing table 8 and the feeding conveyor line 5. It is responsible for grasping the goods on the feeding conveyor line 5 and accurately placing them on the pallets on the palletizing table 8.

[0037] During the operation of the equipment, the entire palletizing process is automatic. First, the self-feeding pallet library 2 sends an empty pallet into the pallet temporary storage table 7. The system will detect whether the pallet temporary storage table 7 is idle to ensure that no collision occurs. Then, the push plate mechanism 6 pushes the pallet from the temporary storage table to the palletizing table 8. At the same time, the feeding conveyor line 5 continuously conveys the goods to be palletized.

[0038] The palletizing manipulator 4 starts to work. According to the pre-set palletizing plan, it grasps the goods from the conveyor line and places them into the pallets on the palletizing table 8. This process will be repeated until the entire pallet on the pallet is completed. During this period, the control system will continuously monitor the palletizing process to ensure that each good is correctly placed.

[0039] When a pallet is palletized, the palletizing table 8 will automatically move the full pallet to the discharging table 9. At the same time, the system will instruct the push plate mechanism 6 to push the pallet from the temporary storage table to the palletizing table 8, and the self-feeding pallet library 2 will convey the next empty pallet to the temporary storage table to prepare for the next round of palletizing. Finally, the forklift operator will transfer the palletized pallets on the discharging table 9, completing the entire process.

[0040] This modular design makes the entire workstation easy to install, maintain, and adjust. Each module can be independently disassembled and replaced, which is convenient for transportation and upgrading. At the same time, the modular structure also improves the flexibility of the system and can be quickly adjusted and reconfigured according to different production requirements.

[0041] Embodiment III:

[0042] As shown Figures 1 - 10 in the figure, the palletizing robot 4 in the present invention is composed of three main parts: a lifting structure 10, a multi-axis robotic arm 11, and a suction assembly 12. This design enables the robot to move flexibly in three-dimensional space and precisely complete the palletizing task. The lifting structure 10 is installed on the workstation, which allows the entire robotic arm system to move vertically. The multi-axis robotic arm 11 is fixedly installed on the lifting structure 10 and is the core part of the palletizing robot 4. The multi-axis robotic arm 11 has 5 or more degrees of freedom, allowing the end effector to achieve almost any position and posture in space. Each joint is equipped with a high-precision servo motor and an encoder to ensure the accuracy and repeatability of the movement. The suction assembly 12 is installed at the end of the multi-axis robotic arm 11 and is the part that directly contacts the goods. It consists of multiple vacuum suction cups 17, which are connected to a powerful vacuum pump system. The number, size, and arrangement of the suction cups 17 are optimized according to the type of goods to be processed. The suction assembly 12 also includes a pneumatic pressure sensor for monitoring the suction state to ensure that the goods are firmly grasped.

[0043] During operation, the lifting mechanism first adjusts the overall height of the robotic arm so that it can reach goods and stacking positions at different heights. The multi-axis robotic arm 11 precisely controls the position and posture of the end suction assembly 12 to approach the target goods. When the suction assembly 12 contacts the surface of the goods, the vacuum system is activated to firmly grasp the goods. The robotic arm then lifts the goods and moves them to the designated position on the pallet through a series of pre-programmed actions. During this process, the multiple joints of the robotic arm work together to achieve complex trajectory movements and avoid collisions with the surrounding environment. After reaching the target position, the vacuum system releases the goods to complete a palletizing operation.

[0044] Throughout the process, the control system continuously monitors the position, speed, and acceleration of the robot to ensure the smoothness and accuracy of the movement. At the same time, the system also monitors the state of the suction assembly 12 to prevent the goods from accidentally falling off. By adjusting the height of the lifting structure 10, the robot can easily meet the palletizing requirements at different heights, greatly improving the adaptability and efficiency of the workstation.

[0045] Embodiment 4:

[0046] As Figures 1 - 10As shown in the figure, the lifting structure 10 of the present invention is composed of three main parts: a first fixed frame 13, a lifting frame 14, and a driving device 15. It allows the multi-axis robotic arm 11 to move freely in the vertical direction, significantly expanding the working range. The first fixed frame 13 is the foundation of the entire lifting structure 10 and is firmly installed on the main structure of the workstation. On both sides inside the fixed frame, linear slide rails 16 are installed. The lifting frame 14 is a movable frame structure that cooperates with the slide rails 16 on the fixed frame. Sliders matching the slide rails 16 are installed on the lifting frame 14 to reduce friction and improve the motion accuracy. An installation platform is provided on the lifting frame 14 for fixing the multi-axis robotic arm 11. The driving end of the driving device 15 is connected to the lifting frame 14 to provide lifting power. Its driving methods include rack and pinion transmission, ball screw transmission, or hydraulic cylinder drive. Taking rack and pinion transmission as an example, a rack is installed on the fixed frame and meshes with the pinion connected to the lifting frame 14. A high-precision servo motor drives the pinion to rotate through a reducer, thereby driving the entire lifting frame 14 to move up and down. The driving device 15 is also equipped with a braking system to ensure that it can stop quickly and lock the position in case of power failure or emergency.

[0047] During actual operation, the control system will precisely control the movement of the driving device 15 according to the requirements of the palletizing task. When the height needs to be adjusted, the servo motor starts and drives the lifting frame 14 to move along the slide rails 16 of the fixed frame through the rack and pinion mechanism. The position of the lifting frame 14 is real-time fed back to the control system through a high-precision encoder to form a closed-loop control and ensure the position accuracy.

[0048] Example Five:

[0049] As Figures 1 - 10 shown in the figure, the adsorption component 12 of the present invention is directly responsible for grasping and releasing goods. The adsorption component 12 is provided with a plurality of suction cups 17, and this design greatly improves the adsorption stability and adaptability. The adsorption component 12 is made of lightweight but high-strength materials, such as aluminum alloy or engineering plastics, to reduce the load at the end of the robotic arm. At the bottom of the component, a plurality of suction cups 17 are evenly distributed. The number, size, and arrangement of these suction cups 17 are optimized according to the type of goods to be processed. Each suction cup 17 is connected to a vacuum system. The vacuum system includes a central vacuum pump and distribution pipes. The vacuum pump can quickly generate a strong negative pressure and distribute it to each suction cup 17 through the pipes. Between the suction cup 17 and the pipes, solenoid valves or pneumatic valves are installed to control the adsorption and release of each suction cup 17. The suction cup 17 itself is made of soft but wear-resistant materials, such as silicone or special rubber. This material can adapt to minor surface unevenness and provide a good sealing effect.

[0050] In actual operation, when the robotic arm moves the adsorption component 12 to the surface of the goods, the control system activates the vacuum system. Multiple suction cups 17 simultaneously contact the surface of the goods and form a seal. The vacuum pump quickly evacuates the air between the suction cups 17 and the goods, generating a strong adsorption force. This multi-point adsorption method not only increases the total adsorption force but also improves the stability of grasping.

[0051] To improve the intelligence and safety of the system, the adsorption component 12 is also equipped with a variety of sensors. For example, each suction cup 17 is equipped with a pressure sensor to monitor the adsorption state. If a certain suction cup 17 loses adsorption force, the system can immediately detect it and take corresponding measures. In addition, proximity sensors can be used to precisely control the distance between the suction cup 17 and the surface of the goods to ensure the best contact state.

[0052] When releasing the goods, the control system instructs the vacuum valve to open, quickly releasing the negative pressure. To ensure the goods are placed smoothly, some designs introduce a small amount of positive pressure air during the release process to help quickly separate the suction cup 17 and the surface of the goods.

[0053] Embodiment Six:

[0054] As Figures 1 - 10 shown, the push plate mechanism 6 of the present invention includes a bracket 18, a first drive motor 19, and a push rod assembly 20. The bracket 18 is welded from steel and has a rectangular frame structure. The bracket 18 is equipped with a smooth shaft 21 made of high-precision ground steel. The push rod assembly 20 includes a push rod and a slider. The slider is sleeved on the smooth shaft 21 through a bearing and can slide freely along the smooth shaft 21. The push plate is fixedly connected to the slider and moves together with the slider. A first drive motor 19 is installed on one side of the bracket 18, and a driving wheel is installed on the motor shaft. A driven wheel is installed on the other side of the bracket 18, and a belt 23 is tensioned between the driving wheel and the driven wheel. The belt 23 is a synchronous belt and is fixedly connected to the slider of the push rod assembly 20.

[0055] When the push plate mechanism 6 works, the first drive motor 19 starts, driving the belt 23 to move through the driving wheel. The belt 23 drives the push rod assembly 20 fixedly connected to it to move along the smooth shaft 21. The smooth shaft 21 ensures that the push rod assembly 20 moves in a straight line without deviation. The push plate moves with the push rod assembly 20, pushing the card plate on the card plate storage table 7 to the palletizing table 8 position. After the pushing is completed, the first drive motor 19 reverses, driving the push rod assembly 20 back to the initial position, waiting for the next push.

[0056] Embodiment Seven:

[0057] As Figures 1 - 10As shown, the pallet temporary storage table 7 and the palletizing table 8 of the present invention are the same mechanism, both of which include a second fixed frame 24, a second driving motor 25 and a number of second roller shafts 26. The second fixed frame 24 is welded by section steel and has a square frame structure. The second fixed frame 24 is provided with a plurality of bearing seats for installing the second roller shafts 26. The second roller shafts 26 are made of high-strength steel and the surfaces are hardened to enhance wear resistance. Each end of each second roller shaft 26 is installed on the bearing seat through a bearing and can rotate freely. A second driving motor 25 is installed on one side of the second fixed frame 24, and a sprocket is installed on the motor shaft. A sprocket is also installed at one end of each second roller shaft 26. All the sprockets are connected by a chain to form a chain drive system. The second driving motor 25 is connected to all the second roller shafts 26 through chain drive and can drive all the roller shafts to rotate simultaneously.

[0058] When the pallet temporary storage table 7 and the palletizing table 8 need to move the pallet, the second driving motor 25 is started, and all the second roller shafts 26 are driven to rotate synchronously through chain drive. The pallet placed on the roller shafts moves forward under the frictional force of the roller shafts. When the pallet reaches the specified position, the second driving motor 25 stops and the pallet stops moving.

[0059] The modular design of the pallet temporary storage table 7 and the palletizing table 8 enables them to be installed and disassembled as independent units. Each tabletop has its own second fixed frame 24, second driving motor 25 and roller shaft system, forming a complete functional module. When maintenance or replacement is required, only the fixing bolts need to be loosened, and the entire tabletop module can be removed from the workstation. This design greatly simplifies the maintenance and replacement process and reduces the downtime.

[0060] Since the pallet temporary storage table 7 and the palletizing table 8 adopt the same modular structure, they can be interchangeably used. This standardized design increases the flexibility of the workstation and facilitates adjusting the workstation layout according to actual needs. For example, the number of pallet temporary storage tables 7 can be increased or decreased according to production requirements, or the relative positions of the pallet temporary storage table 7 and the palletizing table 8 can be adjusted.

[0061] Embodiment Eight:

[0062] As Figures 1 - 10As shown in the figure, the blanking table 9 of the present invention includes a third fixing frame 27, a third driving motor 28, and a plurality of third roller shafts 29. The third fixing frame 27 is welded by steel sections and has a square frame structure. The third fixing frame 27 is provided with a plurality of bearing seats for installing the third roller shafts 29. The third roller shafts 29 are made of high-strength steel and the surfaces are hardened to enhance wear resistance. Each end of each third roller shaft 29 is installed on the bearing seat through a bearing and can rotate freely. A third driving motor 28 is installed on one side of the third fixing frame 27, and a sprocket is installed on the motor shaft. A sprocket is also installed at one end of each third roller shaft 29. All the sprockets are connected by a chain to form a chain drive system. The third driving motor 28 is connected to all the third roller shafts 29 through the chain drive and can drive all the roller shafts to rotate simultaneously. A fork insertion port 30 is provided on one side of the blanking table 9 to facilitate the forklift to pick up the pallet.

[0063] When the pallet with the stacked goods is moved from the palletizing table 8 to the blanking table 9, the third driving motor 28 is started, and all the third roller shafts 29 are driven to rotate synchronously through the chain drive. In cooperation with the palletizing table 8, the pallet placed on the roller shafts moves towards the fork insertion port 30 under the frictional force of the roller shafts. When the pallet reaches the position of the fork insertion port 30, the third driving motor 28 stops and the pallet stops moving. The forklift operator can fork away the pallet through the fork insertion port 30.

[0064] The modular design of the blanking table 9 enables it to be installed and disassembled as an independent unit. The entire blanking table 9 includes a third fixing frame 27, a third driving motor 28, and a roller shaft system, forming a complete functional module. When maintenance or replacement is required, simply loosen the fixing bolts and the entire blanking table 9 module can be removed from the workstation. This design greatly simplifies the maintenance and replacement process and reduces the downtime.

[0065] The modular design also improves the flexibility of the blanking table 9. For example, the position and direction of the blanking table 9 can be adjusted according to actual needs to adapt to different factory layouts and logistics routes. If it is necessary to increase the blanking capacity, additional blanking table 9 modules can also be easily added.

[0066] Embodiment Nine:

[0067] As Figures 1 - 10As shown, a slide plate 31 is provided between the pallet temporary storage station 7 and the stacking station 8 of the present invention. The slide plate 31 is made of metal material, and the surface is polished to reduce friction. The length of the slide plate 31 is slightly greater than the width of the pallet. The two ends of the slide plate 31 are respectively fixed to the adjacent edges of the pallet temporary storage station 7 and the stacking station 8 to form a smooth transition area. The upper surface of the slide plate 31 is kept horizontal with the upper surfaces of the pallet temporary storage station 7 and the stacking station 8 to ensure that the pallet will not tilt or get stuck during the transfer process. The setting of the slide plate 31 allows a certain distance to be maintained between the pallet temporary storage station 7 and the stacking station 8, and such a design effectively prevents mutual interference between the two workbenches during operation. When the push plate mechanism 6 pushes the pallet from the pallet temporary storage station 7 to the stacking station 8, the slide plate 31 plays a role of receiving and guiding. When the pallet slides over the slide plate 31, due to the smooth surface, the friction force is greatly reduced, so that the pallet can be smoothly transferred from the pallet temporary storage station 7 to the stacking station 8. The installation of the slide plate 31 is detachable and fixed to the pallet temporary storage platform 7 and the stacking platform 8 by bolts. This design is convenient for daily maintenance and cleaning, and can also be easily replaced when the slide plate 31 is worn or damaged. A supporting structure can be set under the slide plate 31 to enhance its load-bearing capacity and ensure that it will not deform or sink during long-term use.

[0068] Embodiment ten:

[0069] like Figures 1 - 10 As shown, a protective net 32 is fixedly installed on the periphery of the working platform 1 of the present invention. The protective net 32 adopts a metal grid structure with a small grid spacing, which can effectively prevent foreign objects from entering the working area. The height of the protective net 32 covers the height of the entire workstation. The bottom of the protective net 32 is fixed to the edge of the working platform 1 by bolts. The installation of the protective net 32 adopts a modular design and consists of a plurality of grid units of standard sizes. This design allows the protective net 32 to be flexibly assembled according to the actual size of the workstation, and is also convenient for future maintenance and replacement. Each grid unit is connected by a quick connector, which not only ensures the stability of the structure, but also facilitates disassembly and assembly. The surface of the protective net 32 is rust-proofed and sprayed, which not only enhances durability but also improves appearance. The spray color selects a bright warning color, such as yellow or orange, to enhance the warning effect. Warning signs and safety instructions are also installed at appropriate positions of the protective net 32 to remind staff to pay attention to safety.

[0070] Embodiment eleven:

[0071] like Figures 1 - 10As shown in the figure, a control console 33 is placed beside the working platform 1 of the present invention. The control console 33 adopts a vertical design, and its height is suitable for the operator to stand and operate. A large-sized touch screen is provided on the front of the control console 33 as the main human-machine interaction interface. To meet the needs of different operators, the height of the control console 33 can be finely adjusted. By adjusting the length of the support legs, the height of the control console 33 can be adjusted within a certain range to meet the comfort requirements of operators of different heights.

[0072] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
