[0002] AGV (Automated Guided Vehicle) intelligent handling robots are intelligent logistics equipment based on automatic navigation technology, mainly used in manufacturing, special industries, catering services, and food and pharmaceutical fields. They achieve autonomous movement through technologies such as magnetic strips, lasers, RFID, and SLAM. Among these, magnetic strip navigation is the most common solution due to its low cost, while RFID navigation has become an important supplementary solution due to its high precision and flexibility.

[0003] In existing forklift-type AGV robots, the forks insert into the bottom of the pallet to lift and transport the goods to their destination. During transport, due to the different centers of gravity of different goods and the inertia caused by turning and speed changes, the goods and pallets shift, affecting the stability of the transport and making them prone to tipping over. Therefore, designing an inbound / outbound AGV robot to address this problem is a current challenge. Utility Model Content

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 4The AGV robot shown includes a robot body 1, a fork arm 2 slidably connected to one side of the robot body 1, and the fork arm 2 is fixedly connected to a lifting component on the robot body 1. A connector 3 is fixedly connected to the outer wall of the fork arm 2, and a pressure block 4 is slidably connected inside the connector 3. A first spring 5 is fixedly installed inside the pressure block 4. The first spring 5 is fixedly installed inside the connector 3. A support assembly is used to assist the fork arm 2 in supporting and limiting the pallet of goods. The support assembly is connected to the fork arm 2, the connector 3, and the pressure block 4.

[0016] like Figures 2 to 4 As shown, the support assembly includes a groove 6 formed on one side of the pressure block 4. The groove 6 consists of an inclined section and a straight groove section. A slide rod 7 is slidably connected inside the groove 6. A connecting rod 8 is fixedly connected to one end of the slide rod 7. The connecting rod 8 is slidably connected inside the connector 3. A toothed plate 9 is fixedly connected to one end of the connector 3. A first gear 10 meshes with one side of the toothed plate 9. A support arm 11 is fixedly connected to the top of the first gear 10. The support arm 11 is rotatably connected to the outer wall of the connector 3. The top of the support arm 11 is rotatably connected to... A support plate 12 is fixedly installed on the outer wall of the fork arm 2. A second spring 13 is fixedly installed inside the toothed plate 9. One end of the second spring 13 is fixedly connected to a slider 14. The slider 14 is slidably connected inside the toothed plate 9. A pressure rod 15 is provided on one side of the slider 14. The pressure rod 15 is inserted into the inside of the toothed plate 9. The pressure rod 15 is threadedly connected to the inside of the connecting rod 8. A second gear 16 is fixedly connected to the end of the pressure rod 15 away from the slider 14. A rack 17 is fixedly installed on the side of the pressure block 4 where the groove 6 is opened.

[0017] Working principle: When the robot body 1 moves the fork arm 2 to the bottom of the pallet and controls the fork arm 2 to rise and lift the goods and pallet, the pressure block 4 inside the connector 3 on one side of the fork arm 2 will first contact the bottom of the pallet, so that the pressure block 4 is pressed into the interior of the connector 3. Then the pressure block 4 squeezes the first spring 5 to contract and drives the slide rod 7 to move through the slide groove 6. The slide rod 7 drives the connecting rod 8 to slide along the interior of the connector 3. The connecting rod 8 drives the first gear 10 to rotate through the toothed plate 9. The rotation of the first gear 10 will drive the support arm 11 to rotate and unfold. When the slide rod 7 slides to the connection between the inclined section and the straight section of the slide groove 6, the support arm 11 is driven to rotate to a state perpendicular to the fork arm 2, assisting the fork arm 2 in lifting the pallet. It works with the fork arm 2 to increase the support range of the pallet, prevent the pallet from sliding relative to the fork arm 2 during transportation, improve the stability of the fork arm 2 during transportation, and prevent the pallet from tipping over during transportation, which would cause damage to the goods on the pallet. Furthermore, when the slide rod 7 slides to the connection between the inclined section and the straight section of the slide groove 6, the slide rod 7 drives the second gear 16 to move to the bottom of the rack 17 via the connecting rod 8. As the pressure block 4 continues to descend, the slide rod 7 slides along the straight section of the slide groove 6, causing the rack 17 to mesh with the second gear 16 and drive the second gear 16 to rotate. This causes the second gear 16 to drive the pressure rod 15 to enter the interior of the connecting rod 8 through the thread, thereby locking and fixing the slider 14. This fixes the relative position of the slider 14 and the toothed plate 9, and limits the rotation of the first gear 10 by the toothed plate 9, preventing the support arm 11 from rotating and affecting the support and fixation of the pallet. It should be noted that since the support arm 11 rotates when the fork arm 2 is not in contact with the pallet, this prevents the support arm 11 from rotating. Friction is generated with the pallet during rotation, which improves the flexibility of the support arm 11 during rotation and avoids friction damage. At the same time, when the robot body 1 transports the pallet to the end point and is about to put the pallet down, the fork arm 2 will drive the pallet to gradually descend. When the fork arm 2 drives the pallet to a certain extent, the pallet will be supported by the ground. At this time, the fork arm 2 continues to descend, which will cause the pressure block 4 to gradually lose its compression, so that the first spring 5 can push the pressure block 4 to reset. Then, the pressure block 4 drives the slide rod 7 to reset through the slide groove 6, and drives the second gear 16 to rotate and reset through the rack 17. The slide rod 7 drives the toothed plate 9 through the connecting rod 8 to push the first gear 10 and the support arm 11 to rotate and reset. The second gear 16 drives the pressure rod 15 to stop clamping and fixing the slider 14 and the toothed plate 9, and the support assembly resets to wait for the next work. Furthermore, when the support arm 11 is blocked by the pallet before rotating to be perpendicular to the fork arm 2, and the toothed plate 9 cannot drive the first gear 10 to rotate, the toothed plate 9 will move away from the first gear 10, causing the slider 14 to retract into the interior of the toothed plate 9 and compress the second spring 13 to retract, so that the toothed plate 9 no longer meshes with the first gear 10, allowing the toothed plate 9 to continue moving and avoid jamming. After the toothed plate 9 and the slider 14 are locked together, the rotation of the first gear 10 can be limited, preventing the support arm 11 from driving the first gear 10 to rotate and affecting the support limit of the pallet, so as to achieve the effect of avoiding the pallet, thereby adapting to pallets of different sizes and improving the applicability of the AGV robot. It should be noted that due to the setting of the second spring 13 and the slider 14, the toothed plate 9 will always be against the outer wall of the first gear 10.
