Technical Field

[0001] This utility model relates to the technical field of tire production, and in particular to a laser cleaning device for aircraft tires. Background Technology

[0002] When performing noise reduction on tires, the inner lining (or inner wall) of the tire must first be cleaned, followed by noise reduction treatment (applying noise-reducing materials). Laser cleaning is commonly used, and existing laser cleaning equipment mainly consists of laser guns or laser generators. Existing technology publication number CN217616542U discloses a laser tire cleaning device, including a laser controller, upper tire gripper, lower tire gripper, a rotary table, a lifting gantry, an inlet conveyor belt, an outlet conveyor belt, and a lifting mechanism. The laser controller moves vertically / horizontally. The upper tire gripper is mounted on the lifting gantry and moves vertically along the gantry and radially along the tire. The lower tire gripper is fixedly connected to the rotary table and rotates with the rotary table and moves radially along the tire. The inlet and outlet conveyor belts are mounted on the rotary table via the lifting mechanism, moving synchronously vertically and horizontally. However, this method is cumbersome and complex when clamping and fixing the tire, affecting work efficiency. Utility Model Content
