[0002] AGV (Automated Guided Vehicle) intelligent material handling robots are intelligent logistics equipment based on automatic navigation technology, mainly used in manufacturing, specialized industries, catering services, and food and pharmaceutical fields. They achieve autonomous movement through technologies such as magnetic strips, lasers, RFID, and SLAM. Magnetic strip navigation is the most common solution due to its low cost, while RFID navigation is an important supplementary solution due to its high precision and flexibility. QR code navigation is the second-generation mainstream technology, and laser and visual SLAM algorithm navigation, as the third-generation technology, can operate without ground handling. These robots possess automated material transportation, intelligent scheduling, and path planning functions, with load capacities ranging from 500-1000 kg to 300 tons.

[0003] In existing technologies, the material carrier trays of AGV intelligent handling robots are all smooth optical discs with anti-slip components on the surface of the trays. However, this method has poor material restraint during transportation, and materials are prone to falling during transportation, resulting in poor restraint and low safety. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing AGV intelligent handling robots use smooth optical discs on their material carriers with anti-slip components on the surface. However, this method has poor material restraint during transportation, leading to material falling and low safety. Therefore, this invention proposes a multi-station AGV handling device with safety protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an AGV multi-station handling device with safety protection, comprising an AGV trolley body, a bearing plate at the upper end of the AGV trolley body, an end groove at the upper end of the bearing plate, a sliding groove at the lower end of the end groove, an inner pull plate inside the sliding groove, an inner sealing rubber pad fixedly connected to the outer surface of the inner pull plate, assembly slots on both sides of the middle part of the upper end of the inner pull plate, permanent magnets fixedly connected inside the assembly slots, assembly openings on both sides of the middle part of the lower end of the sliding groove, electromagnets fixedly connected inside the assembly openings, and sealing rubber pads fixedly connected inside the end groove and at both the outer and inner edges of the inner pull plate, the thickness of the sealing rubber pad being greater than the thickness of the anti-slip rubber pad, and the upper end surface of the inner sealing rubber pad being below the anti-slip rubber pad.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up an electromagnet and an inner pull plate, when the material is being transported and carried, the material is squeezed, causing the sealing rubber pad to deform and fill the lower end of the material, forming a sealed space. Then, by changing the magnetic poles of the electromagnet, the permanent magnet is attracted, thereby moving the inner pull plate downward, reducing the air pressure below the material, and thus attracting the material onto the carrying plate, preventing the material from tilting, protecting the material, improving the stability of the material transport, and thus improving the safety of the transport. The anti-slip rubber pad, sealing rubber pad, and inner sealing rubber pad are used to protect the bottom of the material, improve the anti-slip effect, and increase the connection stability.

[0013] 2. In this utility model, the guide sleeve is used to increase the guiding effect on the guide rod and ensure the lifting stability of the bearing plate. The ventilation groove is used to ensure that gas can enter and exit below the inner pull plate, ensuring constant air pressure and stable movement of the inner pull plate. The bottom limit plate is used to limit the movement range of the inner pull plate to prevent it from detaching. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a multi-station AGV handling device with safety protection, including an AGV trolley body 1. A bearing plate 5 is provided at the upper end of the AGV trolley body 1. An end groove 11 is opened at the upper end of the bearing plate 5. A sliding groove 16 is opened at the lower end of the end groove 11. An inner pull plate 17 is provided inside the sliding groove 16. An inner sealing rubber pad 8 is fixedly connected to the outer surface of the inner pull plate 17. Assembly slots 22 are opened on both sides of the middle part of the upper end of the inner pull plate 17. A permanent magnet 18 is fixedly connected inside the assembly slots 22. Assembly openings 13 are fixedly connected on both sides of the middle part of the lower end of the sliding groove 16. An electromagnet 20 is fixedly connected inside the assembly openings 13. Sealing rubber pads 7 are fixedly connected inside the end groove 11 and at the outer and inner edges of the inner pull plate 17. The thickness of the sealing rubber pad 7 is greater than the thickness of the anti-slip rubber pad 6. The upper surface of the inner sealing rubber pad 8 is located below the anti-slip rubber pad 6.

[0019] The specific settings and functions of this embodiment are described in detail below. Through the arrangement of the electromagnet 20 and the inner pull plate 17, during the transport and handling of materials, the material's compression causes the sealing rubber pad 7 to deform, filling the lower end of the material and forming a sealed space. Subsequently, by changing the magnetic poles of the electromagnet 20, the permanent magnet 18 is attracted, thereby moving the inner pull plate 17 downwards, reducing the air pressure below the material, thus allowing the material to be attracted onto the carrying plate 5, preventing material tilting, protecting the material, improving the stability of material transport, and thus improving transport safety. The anti-slip rubber pad 6, sealing rubber pad 7, and inner sealing rubber pad 8 are used to protect the bottom of the material, improving the anti-slip effect and increasing connection stability.

[0020] Example 2: Figure 1 - Figure 5 As shown, an anti-slip rubber pad 6 is fixedly connected inside the end groove 11 and at the outer edge of the sealing rubber pad 7. Guide blocks 19 are fixedly connected to both sides of the lower middle part of the inner pull plate 17. The guide blocks 19 are slidably connected to the bearing plate 5. The lower end of the guide blocks 19 is fixedly connected to the bottom limit plate 15. A ventilation groove 21 is opened in the middle of the guide blocks 19. The lower end of the bearing plate 5 is fixedly connected to the guide rod 12. An electric telescopic rod 10 is fixedly connected to the middle of the AGV body 1. The output end of the electric telescopic rod 10 is fixedly connected to the lower end of the bearing plate 5. A drive wheel 2 is installed in the middle of the AGV body 1. Steering wheels 3 are installed at the four corners of the AGV body 1. A control panel 4 is installed on one side of the AGV body 1. A guide sleeve 9 is fixedly connected inside the AGV body 1. The guide rod 12 is slidably connected to the guide sleeve 9. The lower end of the assembly port 13 is fixedly connected to the bottom cover 14.

[0021] The overall effect of this embodiment is that the guide sleeve 9 is used to increase the guiding effect of the guide rod 12 and ensure the lifting stability of the bearing plate 5. The ventilation groove 21 is used to ensure that gas can enter and exit below the inner pull plate 17, ensuring constant air pressure and stable movement of the inner pull plate 17. The bottom limit plate 15 is used to limit the movement range of the inner pull plate 17 to prevent the inner pull plate 17 from detaching.

[0022] The usage and working principle of this device are as follows: When in use, this device is placed at multiple workstations for multi-station material handling. During handling, the robotic arm places the material on the carrier plate 5. When the material is placed in, the material squeezes and deforms the sealing rubber gasket 7, creating a sealed space at the bottom of the material. Then, the magnetic poles of the electromagnet 20 reverse, attracting the permanent magnet 18, which causes the inner pull plate 17 to move downward, creating a negative pressure in the sealed space at the bottom of the material and attracting the material. Then, the drive wheel 2 and the steering wheel 3 operate to move to the next workstation, where the robotic arm removes the material for transfer. At the same time, the electrodes of the electromagnet 20 reverse again, causing the inner pull plate 17 to move upward.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
