[0030] Furthermore, both the first and second flipping areas include rollers 5, flipping frames 6, pressure frames 7, cylinders 8, and motors 9. The flipping frame 6 has a cuboid structure, and support plates 20 are fixedly installed on both sides of the flipping frame 6 to enhance the stability of the flipping frame 6 structure. Multiple rollers 5 are rotatably installed on both the flipping frame 6 and the pressure frame 7. The motor 9 is fixedly installed on the frame 1 and drives the flipping frame 6 to flip. The drive shaft 21 of the motor 9 is fixedly connected to the middle position of the support plate 20 on one side of the flipping frame 6, thereby driving the flipping frame 6 to flip 180°.

[0031] The flipping frame 6 is equipped with the pressure frame 7 inside. Two cylinders 8 are fixedly installed on both sides of the upper flipping frame 6. The output end of the cylinder 8 is fixedly connected to the connecting plate 22 on the pressure frame 7. The cylinder 8 is used to drive the pressure frame 7 to move up and down.

[0032] Furthermore, multiple U-shaped grooves 10 are provided on both sides of the pressure frame 7. The U-shaped grooves 10 are adapted to the rollers 5 on the flipping frame 6, so that the rollers 5 on the pressure frame 7 and the rollers 5 on the flipping frame 6 are staggered, making the pressure frame 7 fit more closely with the upper flipping frame 6, expanding the placement space of the tire 17, and meeting the needs of flipping and engraving tires of different specifications.

[0033] Furthermore, the engraving area includes a conveying device and a scanning engraving device. The conveying device is used to convey the tire 17 to the area below the scanning engraving device, and the scanning engraving device is used to scan and engrave the tire 17.

[0034] Furthermore, the conveying device includes a rotating shaft 11 and a transmission block 12. The rotating shaft 11 is rotatably mounted on the frame 1. A plurality of transmission blocks 12 are fixedly mounted on the rotating shaft 11. Each transmission block 12 includes a fixing frame 121 and a shuttle roller 122. The fixing frame 121 is sleeved on the rotating shaft 11, and the shuttle roller 122 is fixedly mounted on the fixing frame 121 and arranged in a ring array.

[0035] Compared to traditional rollers, the transmission block 12 can support and position the tire 17 from multiple directions, effectively limiting the swaying and offset of the tire 17 during the transmission process, ensuring the accurate position of the tire 17 in the engraving area, and improving the engraving quality.

[0036] Furthermore, the scanning and engraving device includes a support frame 13, a camera 14, and a laser 15. The camera 14 is a 3D camera. The support frame 13 is fixedly mounted on the frame 1. The camera 14 is mounted on the support frame 13 and arranged facing the rotating shaft 11. A robotic arm 16 is mounted on one side of the support frame 13. The laser 15 is fixedly mounted on the robotic arm 16 to engrave characters on the tire 17.

[0037] Furthermore, the robotic arm 16 is also equipped with a 2D camera 23, which is used to locate the tire DOT and to re-inspect the engraved tire 17 to ensure that the engraved content is intact and correct.

[0038] Furthermore, a fume purifier 18 is installed on the frame 1 on the side of the robotic arm 16. When the laser 15 is working, it vaporizes the material on the surface of the tire 17 through burning and etching, and the particles are dispersed into the air in a gaseous manner to form fume. The fume purifier 18 can prevent it from polluting the production environment, reduce equipment failure, and also prevent employees from inhaling harmful substances, thus protecting their health.

[0039] Furthermore, a guardrail 19 is fixedly installed on the outer side of the frame 1, which provides a good safety protection effect.

[0041] Furthermore, the conveyor roller 2, the drum 5, and the rotating shaft 11 all rotate under the combined action of the motor, chain, and sprocket.

[0042] The working principle is as follows:

[0043] The tire 17 to be engraved is sent by the MES to the front-end automated logistics system to be assigned to the conveying area. Under the action of the conveying roller 2 in the conveying area, it is conveyed forward. During the conveying process, the forming barcode on the tire 17 is read by the panoramic scanning dock 3 and uploaded to the MES. The MES sends it to the WMS system of the laser 15 to confirm the engraving position and content.

[0044] After confirmation, the tire 17 is transported to the first flipping area to determine whether the engraving position is on the upper or lower layer. If flipping is required after the determination, the cylinder 8 is started. The cylinder 8 drives the pressure frame 7 to press the tire 17 down. Then the motor 9 is started to drive the entire flipping frame 6 to flip 180°. After the flipping is completed, the cylinder 8 is started to drive the pressure frame 7 to move down so that it is on the same plane as the transmission block 12 of the engraving area. Then the tire 17 enters the engraving area along the roller 5 of the pressure frame 7.

[0045] After entering the engraving area, the 3D camera 14 takes a picture of the tire 17 to generate a three-dimensional scanning model, determine the tire sidewall angle, inner diameter and outer diameter of the tire, the 3D camera 14 finds the tire's unique identifier, and transmits it to the robot arm 16 via network interaction. Then, the 2D camera 23 on the robot arm 16 finds the tire's DOT, confirms the DOT coordinates, and transmits them to the 3D camera 14 to calculate the position to be engraved. The calculation result is sent to the robot arm 16, which drives the laser 15 to the designated position for engraving. After the engraving is completed, the 2D camera 23 is used for re-inspection to ensure that the engraved content is intact and correct.

[0046] After the carving inspection is passed, tire 17 is transported through the second turning area to the qualified channel conveyor line.
