Description

Technical Field

[0001] This utility model relates to the field of tire mold technology, specifically to an automated laser cleaning system for tire molds. Background Technology

[0002] Currently, there are two main methods for cleaning tire molds. The first method is to clean the tire mold manually. The mold is fixed in place, and a person holds a laser head to irradiate the surface of the mold and clean it. However, because the laser head and its connecting pipes are heavy and the speed of manual movement is unstable, the cleaned mold has color differences and ablation defects, resulting in poor cleaning effect.

[0003] The second method involves automatically cleaning tire molds. The laser head and fiber optic cable are fixed to a robotic arm, while the tire mold itself remains stationary. A motor drives the robotic arm and laser head, causing them to move and rotate simultaneously. The laser irradiates the mold surface, cleaning the tire mold. Because the tire mold is a ring-shaped component, the equipment, driving the laser head (including the fiber optic cable), needs to perform not only moving motions but also periodic forward and reverse rotations around the mold's ring surface. Directional rotation can damage the connecting fiber optic cables and control circuitry, resulting in complex equipment control, higher costs, and a higher risk of damage.

[0004] To address the aforementioned issues, an improved automated laser cleaning system for tire molds is now designed. Utility Model Content
