However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0013] See Figure 1 and Figure 2 This utility model relates to an automatic material handling device that enhances flipping stability, comprising a base 1, a rotary drive assembly, a first drive assembly, a second drive assembly, and a flexible material handling assembly.

[0015] The rotary drive assembly is controlled by a servo motor, enabling precise rotation at multiple angles to meet the requirements for flipping at different angles during the production of riveted boxes, ensuring that the workpiece can accurately reach the designated position.

[0016] The flexible material handling assembly is equipped with multiple layers of suction cups, which can gently grip the workpiece, avoiding scratches or other damage and improving the product yield. At the same time, the use of multiple layers of suction cups also increases the device's adaptability to workpieces of different shapes and sizes.

[0017] The design of the guide column and linear bearing in the first drive assembly ensures that the flexible material handling assembly moves in a straight line during the push-pull process, improving the accuracy and stability of the action and avoiding workpiece damage or device failure caused by motion deviation.

[0022] The speed reduction of the servo motor is reduced by the speed reducer 4, while the torque is increased, enabling the rotating shaft 14 to rotate smoothly and powerfully. The application of the speed reducer not only improves the transmission efficiency of the drive system, but also enhances the load capacity of the device, ensuring stable operation even when flipping heavy workpieces.

[0023] The first driving mechanism includes a rotating base 2, a receiving cylinder 5, a guide shaft 7, and a connecting base plate 8. The rotating base 2 is fixedly mounted on the rotating shaft 14. A counterweight is installed on one side of the rotating base 2, and the receiving cylinder 5 is installed on the other side. A guide shaft 7 is installed on the rotating base 2 on the upper and lower sides of the receiving cylinder 5, and is parallel to the receiving cylinder 5. Each guide shaft 7 is guided by a linear bearing 6 installed on the rotating base 2.

[0025] A counterweight is installed on one side of the rotating base 2 to balance the weight distribution of the rotating base 2 and its components. This balancing design helps reduce vibration and swaying during rotation, improves the overall operational stability of the device, and extends the service life of the equipment.

[0026] Guide shafts 7 are respectively set on the upper and lower sides of the receiving cylinder 5 to form a double guide column structure. This design can further enhance the stability of the movement of the connecting base plate 8, disperse the stress during the movement, prevent deformation or damage caused by single-point force, and improve the reliability and durability of the device.

[0027] The receiving cylinder 5 serves as the main power source for pushing and pulling, providing stable and powerful pushing and pulling actions. The cylinder's telescopic rod is connected to the connecting base plate 8, enabling it to quickly and accurately drive the flexible material handling assembly to perform material handling and feeding operations, meeting the cycle time requirements of the production process.

[0028] The front ends of the telescopic rod of the receiving cylinder 5 and the guide shaft 7 are both connected to the connecting base plate 8, ensuring the synchronicity of the pushing and pulling actions. This design allows the connecting base plate 8 to remain stable during movement, avoiding motion errors or component damage caused by asynchrony. The connecting base plate 8 is equipped with a product contouring support plate 17, which can support the product from the bottom when the receiving cylinder 5 extends, ensuring the stability of the product during the flipping process.

[0029] The first drive mechanism, through reasonable design and component selection, achieves advantages such as precise linear motion control, enhanced structural stability, efficient push-pull capability, compact structural design, reliability and durability, and ease of adjustment and maintenance, providing an important guarantee for the efficient operation of the automatic material handling device that can enhance the stability of the flipping mechanism.

[0030] The second drive assembly includes a rotating arm 9, a rotating arm cylinder 12, and a pin 16. A rotating arm 9 is respectively provided at the bottom end on both sides of the connecting base plate 8. Each rotating arm 9 is rotatably connected to the connecting base plate 8 through the pin 16. The rotating arm 9 is driven by the corresponding rotating arm cylinder 12.

[0031] The rotating arm 9 is driven by the rotating arm cylinder 12, enabling rapid and precise rotation. The extension and retraction of the cylinder can flexibly control the swing angle of the rotating arm, meeting the material handling and release requirements of different workpieces and improving the adaptability and flexibility of the device.

[0032] The design of the rotating arm 9 enables the flexible material handling assembly to operate at multiple angles, achieving not only horizontal material handling and feeding but also vertical adjustment to accommodate workpieces of different heights, further enhancing the versatility of the device.

[0033] The rotary arm cylinder 12 serves as a power source, providing stable and powerful driving force. The extension and retraction of the cylinder is transmitted to the rotary arm 9 via the pin 16, enabling rapid rotation and meeting the speed and efficiency requirements of the production process.

[0034] Each rotating arm 9 is equipped with an independent rotating arm cylinder 12, ensuring synchronous movement of the two rotating arms. This design avoids motion errors caused by inconsistent power transmission, improving the accuracy and reliability of the device.

[0035] The second drive assembly, through the combined design of the rotating arm 9, the rotating arm cylinder 12 and the pin shaft 16, achieves advantages such as flexible rotational movement, stable rotational connection, efficient power transmission, reliability and durability, easy adjustment and maintenance, and enhanced safety, providing an important guarantee for the efficient operation and stable operation of the automatic material handling device that can enhance the stability of the flipping.

[0036] The cylinder body of the rotating arm cylinder 12 is hinged to the top of the connecting base plate 8, and the telescopic rod of the rotating arm cylinder 12 is hinged to the rotating arm 9.

[0037] The flexible material handling assembly includes multiple suction cups 10 and multiple suction cup connectors 11. The multiple suction cup connectors 11 are mounted on the front end of the connecting base plate 8 and on the rotating arm 9. Each of the multiple suction cup connectors 11 has a multiple suction cup 10 connected to a vacuum pump. Using multiple suction cups as the material handling tool allows for gentle clamping of workpieces through vacuum adsorption. When encountering products with curved surfaces or uneven surfaces, the multiple suction cups can better conform to the product surface, making material handling more stable. This flexible material handling method avoids scratches, indentations, and other damage to the workpiece surface that may be caused by traditional mechanical clamps. It is especially suitable for riveted box-shaped workpieces with high surface precision requirements, effectively improving the product qualification rate.

[0038] The multi-layer suction cup 10 can be adjusted and selected for workpieces of different shapes, sizes, and materials, exhibiting excellent versatility and adaptability. For example, reliable adsorption can be achieved for flat workpieces, curved workpieces, or workpieces with holes by selecting appropriate multi-layer suction cup shapes and sizes.

[0039] A bearing 15 is installed between the rotating shaft 14 and the motor mounting bracket 3.

[0040] This utility model is an automatic material handling device that can enhance the stability of flipping. Its working principle is based on the coordinated work of a rotary drive component, a first drive component, a second drive component, and a flexible material handling component, as detailed below: 1. Initial state Device preparation: The device is in the initial position. The flexible material handling assembly, including the multiple layers of suction cups 10 and the multiple layers of suction cup connectors 11, as well as the multiple layers of suction cups on the rotating arm 9, are all in the material handling position, waiting for the workpiece to arrive.

[0041] System startup: The control box sends a startup signal, and all drive components are ready.

[0042] 2. Material handling process Rotary drive component action: The servo motor drives the rotating shaft 14 to rotate through the reducer 4, causing the rotating base 2 to rotate to the material picking position.

[0043] A bearing 15 is installed between the rotating shaft 14 and the motor mounting bracket 3 to ensure smooth rotation and reduce wear.

[0044] The first drive component operates as follows: the telescopic rod of the receiving cylinder 5 extends, pushing the connecting base plate along the guide column towards the material-receiving position. The guide column is guided by the linear bearing 6, ensuring that the connecting base plate moves smoothly in a straight line and avoiding deviation or wobbling. A counterweight is installed on one side of the rotating base 2 to balance the weight distribution of the rotating base and its components, reducing vibration during rotation.

[0045] Flexible material handling component operation: The multi-layer suction cup 10 generates a vacuum through a vacuum pump to adsorb the workpiece. The multi-layer suction cup 10 is mounted on the multi-layer suction cup connector 11, enabling it to gently grip the workpiece and avoid damage. The multi-layer suction cup 10 can be adjusted and selected according to workpieces of different shapes, sizes, and materials, exhibiting good versatility and adaptability.

[0046] The action of the multiple suction cups on the rotating arm: The multiple suction cups on the rotating arm 9 also generate a vacuum through a vacuum pump, which assists the flexible material handling component in adsorbing the workpiece, further improving the stability and reliability of material handling.

[0047] 3. Flipping process Rotary drive component operation: The servo motor precisely adjusts the rotation angle according to the control signal, driving the rotating shaft to rotate, causing the rotating base 2 to rotate to the flip position. The rotation angle and speed of the rotating shaft can be precisely controlled according to production requirements, ensuring that the workpiece can accurately reach the designated position.

[0048] The second drive component operates as follows: the telescopic rod of the rotary arm cylinder 12 extends or retracts, driving the rotary arm 9 to rotate around the pin 16. The swing angle of the rotary arm 9 can be adjusted according to the shape of the workpiece and the flipping requirements, enabling multi-angle flipping operations.

[0049] Each rotating arm 9 is equipped with an independent rotating arm cylinder 12 to ensure synchronous movement of the rotating arms on both sides and avoid motion errors caused by inconsistent power transmission.

[0050] The multiple suction cups 10 on the rotating arm 9 continue to adsorb the workpiece during the flipping process, ensuring that the workpiece will not fall off during the flipping process.

[0051] 4. Feeding process The first drive component operates as follows: the telescopic rod of the receiving cylinder 5 retracts, pulling the connecting base plate along the guide column towards the feeding position. The design of the guide column and linear bearing 6 ensures the linear movement of the connecting base plate during the push-pull process, improving the accuracy and stability of the action.

[0052] Flexible material handling component operation: After the multi-layer suction cups 10 reach the feeding position, the vacuum pump releases the vacuum, and the workpiece is released to the designated position. The suction and release actions of the multi-layer suction cups 10 are rapid and can be completed in a short time, improving the overall production efficiency of the device.

[0053] The action of the multiple suction cups on the rotating arm: After the workpiece reaches the feeding position, the multiple suction cups on the rotating arm 9 also release the vacuum to ensure that the workpiece can be smoothly placed in the designated position.

[0054] 5. Repetitive actions The rotary drive assembly, the first drive assembly, and the second drive assembly work together to return the device to its initial position. Each drive assembly is precisely adjusted according to the control signal to ensure that the device can repeat the action according to the preset rhythm.

[0055] Cyclic operation: By repeating the above steps, continuous automatic material picking, multi-angle flipping, and precise feeding can be achieved to meet the cycle time requirements of the production process.

[0056] This invention relates to an automatic material handling device that enhances rotational stability. It adds several layers of suction cups 10 and a product-contouring support plate 17 to the rotating arm 9. The suction cups 10 can more stably hold workpieces with irregular shapes, while the product-contouring support plate can hold the product during rotation, thus enhancing rotational stability and significantly reducing the likelihood of the product falling during rotation. This further improves the stability, flexibility, and rotational performance of the material handling device, while maintaining advantages such as high-efficiency automated operation, high precision and flexibility, stability and reliability, cost-effectiveness, and integration and controllability. This device effectively solves the problem of products easily falling during rotation in traditional equipment and has broad application prospects.
