This device utilizes high-precision sensors, QR code recognition, wireless communication, and other technologies to accurately and quickly locate material pallets, ensuring that AGVs can accurately and flawlessly handle materials. This is crucial for improving production efficiency, reducing labor costs, and ensuring safety.

[0003] According to the search of China Utility Model Publication No.: CN211495528U, an AGV material pallet positioning device is disclosed. The utility model realizes the precise positioning of the AGV material pallet in five directions of front, back, left, right and height through the above-mentioned pallet guide positioning mechanism 200, pallet receiving mechanism 300 and mechanical positioning mechanism 400. The repeated positioning accuracy can reach ±2mm, so as to meet the accuracy requirements of the robot directly grabbing the pallet and loading the material bin.

Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4The utility model provides an embodiment: an AGV material tray positioning device, including a base 1 and a positioning mechanism 3, a tray 2 is arranged on the upper side of the base 1, the positioning mechanism 3 is arranged above and inside the base 1, a protective frame 301 is arranged in front of the tray 2, a glass 302 is arranged on the outside of the protective frame 301, an infrared locator 303 is arranged inside the protective frame 301, a motor 305 is arranged inside the base 1, and a telescopic rod 313 is arranged on the outside of the motor 305.

[0026] Specifically, the protective frame 301 is made of stainless steel, and the glass 302 is connected to the protective frame 301. The glass 302 is explosion-proof glass. Stainless steel is strong and corrosion-resistant. The explosion-proof glass 302 provides good protection for the internal locator, and the transparent glass material will not affect the positioning effect.

[0027] Specifically, two groups of infrared locators 303 are provided. The side of the infrared locator 303 is electrically connected to the processor 304. The processor 304 is internally provided with a signal transmitter. The infrared locator 303 scans and locates the transporter, transmits the signal to the processor 304 for storage and conversion, converts the optical signal into an electrical signal, and transmits it through the signal transmitter to control the angle and position of the cargo pallet 2 to be transported, so that the cargo is accurately oriented towards the transporter, thereby preventing transportation errors caused by the uneven placement of the cargo.

[0028] Specifically, the side of the motor 305 is electrically connected to a signal receiver 306, and the signal receiver 306 is electrically connected to the processor 304. The top of the motor 305 is connected to a turbine rod 307. The signal receiver 306 receives a signal to control the start of the motor 305, driving the rotation of the turbine rod 307. The device has a high degree of automation.

[0029] Specifically, the side of the turbine rod 307 is meshed with the first bevel gear 308, and the side of the first bevel gear 308 is meshed with the second bevel gear 309. When the turbine rod 307 rotates, it drives the rotation of the first bevel gear 308, and then drives the rotation of the second bevel gear 309. This gear set transmission method has less kinetic energy loss and higher transmission efficiency. At the same time, due to the different weights of the goods, this transmission method can provide a higher torque capacity, the device has a long practical life, and is easy to maintain.

[0030] Specifically, the top of the second bevel gear 309 is connected to the first gear 310, the top of the first gear 310 is connected to the second gear 311, the outer side of the second gear 311 is meshed and connected to the rotating disk 312, and the rotating disk 312 and the tray 2 are fixed structures. When the second bevel gear 309 rotates, it drives the first gear 310 and the second gear 311 to rotate, and the second gear 311 drives the rotating disk 312 to rotate. The setting of the first gear 310 can help balance the load in the system, so that the force applied to the rotating disk 312 is more uniform, reducing vibration and impact, and at the same time playing a good supporting role.

[0031] Specifically, four groups of telescopic rods 313 are provided, and the telescopic rods 313 are electrically connected to the processor 304. When the height of the goods to be transported is inconsistent with the height of the transporter, the processor 304 sends a signal to the telescopic rods 313, and the telescopic rods 313 are extended to change the height of the pallet 2. It is suitable for different types of transporters and avoids the problem of inability to transport due to inconsistent heights.

[0032] Working principle: First, place the goods on the surface of pallet 2, and the infrared locator 303 starts to scan the position of the transporter. When the angle is incorrect, the signal is transmitted to the processor 304 for storage, conversion and transmission. The signal receiver 306 receives the signal to control the motor 305 to start, driving the rotation of the turbine rod 307. When the turbine rod 307 rotates, it drives the rotation of the first bevel gear 308, and then drives the rotation of the second bevel gear 309. When the second bevel gear 309 rotates, it drives the rotation of the first gear 310 and the second gear 311. The second gear 311 drives the rotation of the rotating disk 312 and pallet 2 to align the pallet 2 with the transporter. When the goods to be transported are inconsistent with the height of the transporter, the processor 304 sends a signal to the telescopic rod 313, and the telescopic rod 313 is extended to change the height of the pallet 2.
