Description

Technical Field

[0001] The present invention relates to the technical field of logistics automation, in particular to a positioning AGV vehicle. Background Art

[0002] The AGV reads the QR code on the ground to obtain the coordinate information of the ground facing the QR code. The AGV reads and identifies the QR code through its own high-resolution telephoto camera. At the same time, the rotation of the QR code image in the camera coordinates is integrated with the electronic compass data to determine the precise direction of the AGV. The AGV can be completely positioned by combining the information encoded in the QR code and its position information in the image. Similarly, the AGV can obtain the positional relationship between the AGV and the goods by reading the QR code on the goods being transported.

[0003] However, during the operation of the AGV, there is often a deviation between the preset position and the actual position reached by the AGV, resulting in inaccurate position for transporting or picking up workpieces.

[0026] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0027] Embodiment: When in use, firstly energize the battery 31, and make the steel wire rope 8 slide on the first guide wheel 6 and the second guide wheel 7 by pulling the oil cylinder 5, thereby driving the lifting frame 3 to move up and down, and then adjusting the height of use. When the lifting frame 3 is in the ascending state, there is no gap between the left guide wheel 23 and the lifting frame 3, and the left guide wheel 23 is used to limit the lifting frame 3 and prevent shaking during walking. When the lifting frame 3 is descending, there is a gap between the right guide wheel 33 and the lifting frame 3, thereby leaving a certain space for the guide to avoid, and then the accurate position can be freely determined during the descent. When the rotation function is realized, the vehicle body 1 is moved to the base 11 position, so that the limit block 20 is embedded in the limit column 16, start the motor 12, so that the belt 15 drives the first rotating wheel 13 and the second rotating wheel 14 to rotate synchronously, so that the second gear 19 drives the first gear 18 to rotate, and then the base plate 4 rotates. When the lifting and rotation are completed, the positioning pin 10 under the vehicle body 1 is inserted into the positioning hole on the base plate 4 to determine the position and ensure that the base plate 4 returns to 0 degrees, while maintaining the overall flatness of the vehicle body 1. By setting the reducer 24 in the Mecanum wheel 2, the Mecanum wheel 2 hub replaces the RV reducer 24 housing, thereby reducing the manufacturing cost, improving the overall strength, and saving space. The shock-absorbing block 27 allows the vehicle body 1 to run smoothly during the working process.
