[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] In the existing automatic production system, the feeding process of hollow parts is usually completed by a special feeding station equipped with a U-shaped push plate. Such a traditional scheme generally relies on a composite motion of axial pushing and longitudinal lifting to realize the separation and feeding of the workpiece. First, the stacked hollow parts are sleeved on the guide column, and then the U-shaped push plate performs a series of complex actions such as pushing out a single workpiece horizontally, retreating and lifting to avoid, and resetting horizontally.

[0004] To realize the above-mentioned composite motion, the device needs to be equipped with multiple groups of driving units and corresponding precision guide mechanisms, resulting in a complex mechanical structure. The complex structure also makes the overall feeding station have a large floor area, which restricts the installation flexibility of the device in the workshop. The driving and moving parts of the existing device have large mass and obvious inertia impact, and the impact resistance of the mechanical frame and transmission parts is high. The feeding capacity is limited by the space required for single-station design and push plate avoidance. The storage capacity of a single feeding station is limited, which affects the feeding efficiency of the device. SUMMARY

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment provides a dual-platform loading device for hollow parts, such as... Figures 1-3 As shown, it includes: a workbench 1, on which two loading stations for hollow parts 14 are provided, which can simultaneously provide hollow parts 14 to the production line through the two loading stations, occupying little space, and improving loading efficiency while increasing the amount of material stored. The loading station includes a loading platform 2 and a loading module 3. The loading module 3 is located on one side of the loading platform 2. The loading platform 2 includes a rotating device 5. A rotating disk 6 is provided on the rotating seat 18 of the rotating device 5. The rotating disk 6 is annular, and rectangular teeth 20 are evenly arranged circumferentially along the edge of the rotating disk 6. Guide posts 7 are provided on the rectangular teeth 20 for placing hollow parts 14. A detection bracket 8 and a detection device 9 are arranged at the center of the rotating disk 6. The bottom end of the detection bracket 8 is fixedly mounted on a fixed shaft 19 at the center of the rotating seat 18. The fixed shaft 19 is fixedly connected to the housing of the rotating device 5. The loading module 3 includes a pusher 12. The rectangular teeth 20 are arranged above the center of the pusher 12 to avoid interference between the rotating disk 6 and the pusher 12 when rotating. The pusher 12 is used to push the hollow parts 14 on the guide posts 7 to the top of the guide posts 7 for easy gripping of the hollow parts 14. It can be understood that the rotating device 5 drives the ring. The rotating disk 6 rotates intermittently, with each rotation angle determined by the number of circumferentially evenly distributed rectangular teeth 20. This precisely transfers the rectangular teeth 20 of a guide post 7 already loaded with workpieces to the top of the pusher rack 12 of the loading module 3. Simultaneously, it rotates an empty workstation back to the loading area. Operators can replenish empty guide posts 7 in non-working areas while the equipment is running, without stopping the production line, reducing equipment waiting time and achieving near-continuous production. When the rotating disk 6 stops intermittently, sensors determine the number of hollow parts 14 currently at the workstation. The pusher rack 12 performs a pushing action, pushing the hollow parts 14 on the guide post 7 upwards along the guide post 7 until they are lifted to the top of the guide post 7. This precisely pushes the hollow parts 14 to a uniform height, providing a stable and consistent pick-up point for the gripping mechanism. This completely avoids the risk of gripping failure due to uneven placement of the hollow parts 14, significantly improving the success rate of automated gripping.

[0023] The rotating device 5 includes a driving gear and a driven gear. The driving gear is connected to the drive motor 16 via a drive shaft. The driven gear is mounted on the fixed shaft 19 via bearings. The rotating seat 18 is mounted on the driven gear and is fixedly connected to the rotating disk 6 via fasteners. Both the rotating device 5 and the drive motor 16 are mounted on the worktable 1. It can be understood that both ends of the fixed shaft 19 are fixed to the housing of the rotating device 5. Bearings are provided between the driven gear and the fixed shaft 19, allowing the driven gear to rotate around the fixed shaft 19. The driven gear is connected to the rotating disk 6 via flanges and fasteners. A detection bracket 8 is mounted on the fixed shaft 19, thus ensuring that the detection bracket 8 is fixed and the rotating disk 6 rotates, enabling the detection device 9 on the detection bracket 8 to monitor the hollow parts 14 on different guide columns 7 on the rotating disk 6.

[0024] The detection bracket 8 is a T-shaped structure composed of a vertical pole and a horizontal pole. The horizontal pole is connected to the fixed shaft 19 through a connector. Two detection devices 9 are provided on the vertical pole. The detection devices 9 are laser sensors used to detect the number of hollow parts 14 on the guide column 7. Both the vertical pole and the horizontal pole are made of profiles.

[0025] The rectangular tooth 20 has a first through hole at its center, and the guide post 7 has an internal threaded hole at its bottom end. The rectangular tooth 20 and the guide post 7 are connected by a fastener, which engages with the internal threaded hole on the guide post 7 through the first through hole. The rectangular tooth 20 also has a guide seat 15, which is annular. The guide post 7 is located at the center of the guide seat 15, and the inner ring of the guide seat 15 is clearance-fitted with the guide post 7. The guide seat 15 also has a threaded hole on the side closest to the rectangular tooth 20. The rectangular tooth 20 has a second through hole, and the rectangular tooth 20 and the guide seat 15 are connected by a fastener, which engages with the internal threaded hole on the guide seat 15 through the second through hole.

[0026] As a further implementation, the feeding module 3 also includes a fixed base 11, a lifting guide rail 13, and a lifting seat 10. One side of the lifting guide rail 13 is fixedly connected to the fixed base 11, and the lifting seat 10 is disposed on the other side of the lifting guide rail 13. The pushing frame 12 is disposed on the lifting seat 10. Photoelectric switch transmitters are disposed at both the upper and lower ends of the lifting guide rail 13, and photoelectric switch receivers are disposed on the lifting seat 10 via a bracket. The lifting guide rail 13 and the lifting seat 10 are driven by a servo mechanism, so that the lifting seat 10 moves up and down along the lifting guide rail 13. Understandably, when the photoelectric switch receiver of the lifting platform 10 passes the photoelectric switch transmitter at the upper end of the lifting guide rail 13 during the upward process, the servo mechanism stops driving the lifting platform 10 to move upward. When the lifting platform 10 moves downward and the photoelectric switch receiver passes the photoelectric switch transmitter at the lower end of the lifting guide rail 13, it indicates that the lifting platform 10 has reached the lowest point. This allows the lifting platform 10 to stop precisely at the highest and lowest points of the lifting guide rail 13. By receiving photoelectric signals, it can autonomously decide "when to stop" and "when to proceed with the next action" of the loading platform 2, reducing the reliance on manual intervention.

[0027] As a further implementation, the pusher 12 consists of two L-shaped supports. The distance between the two L-shaped supports is greater than the width of the rectangular teeth 20 and less than the diameter of the hollow component 14. This allows the pusher 12 to lift the hollow component 14 upward from below the rectangular teeth 20, without affecting the rotation of the rotating disk 6 or the lifting and lowering of the pusher 12. This allows the pusher 12 to lift the hollow component 14 upward from below the rectangular teeth 20, accurately pushing the hollow component 14 to a uniform height. This provides a stable and consistent pick-up point for the gripping mechanism, facilitating the subsequent gripping of the hollow component 14.

[0028] As a further implementation, the bottom of the workbench 1 is provided with an adjustable foot cup 4 to adjust the level of the workbench 1. In case the workbench 1 shakes or tilts, a guard plate 17 is provided at the upper edge of the workbench 1 to prevent tools, parts or other foreign objects from accidentally falling into the equipment operating area, causing the equipment to jam, stop or be damaged, and to prevent the operator from being caught or trapped, thus avoiding injury to the operator.

[0029] Example 2 This embodiment provides a method for operating a dual-platform loading device for hollow parts, including the following steps: Step 1: Monitor the number of hollow parts 14 on the guide post 7 using the detection device 9. If there are still hollow parts 14 on the guide post 7, that is, the guide post 7 is filled with hollow parts 14 or there are hollow parts 14 that have not been completely grabbed, then proceed to Step 2; if there are no hollow parts 14, that is, the hollow parts 14 on the guide post 7 have been completely grabbed, then proceed to Step 3. Step 2: The servo mechanism is activated, and the hollow part 14 is lifted by the pusher 12 on the lifting seat 10 until the photoelectric switch receiver on the lifting seat 10 passes the upper photoelectric switch transmitter on the lifting guide rail 13. Then the servo mechanism drives the lifting seat 10 to reset. When the lifting seat 10 moves down and the photoelectric switch receiver passes the lower photoelectric switch transmitter on the lifting guide rail 13, it indicates that the lifting seat 10 has been reset. After resetting, step 1 is executed. Step 3: The drive motor 16 drives the rotating device 5, and the rotating disk 6 rotates at a set angle, so that the adjacent rectangular teeth 20 rotate between the two L-shaped supports of the pusher frame 12. The angle of rotation of the rotating disk 6 is fixed each time. The specific angle is determined by the number of rectangular teeth 20 evenly distributed around the circumference. A rectangular tooth 20 that has been loaded with hollow part 14 is accurately transferred to the center position above the pusher frame 12 of the feeding module 3, and then step 1 is executed.

[0030] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
