Description

Technical Field

[0001] The present invention relates to the technical field of tire molds, specifically an automated laser cleaning system for tire molds. Background Art

[0002] Currently, there are mainly two ways to clean tire molds. First, the manual method is used to clean the tire molds. The mold is fixed, and the worker holds the laser head by hand. The laser irradiates the surface of the mold to clean the tire mold. Since the laser head and its connecting pipelines are heavy, and the speed of manual actions is unstable, there are color differences and ablation defects on the cleaned mold, and the cleaning effect of the mold is poor.

[0003] Second, the tire mold is automatically cleaned. The laser head and the optical fiber pipeline are fixed on the robotic arm. The tire mold is fixed. The robotic arm and the laser head are driven by a motor to move and rotate simultaneously. The laser irradiates the surface of the mold to clean the tire mold. Since the tire mold is an annular part, the equipment drives the laser head (including the optical fiber pipeline). In addition to moving, it also needs to make periodic forward and reverse rotational movements around the annular surface of the mold. The directional rotation will cause damage to the connected optical fibers and control lines. The equipment control is complex, the cost is relatively high, and it is easy to be damaged.

[0004] In view of the above problems, an improved automated laser cleaning system for tire molds is now designed. Summary of the Invention

[0005] The purpose of the present invention is to provide an automated laser cleaning system for tire molds to solve the problems raised in the above background art.

[0034] Working principle of the automatic laser cleaning system for tire molds:

[0035] During use, place the tire mold on the sliding rod 9, and then start the electric telescopic rod 23 to contract.

[0037] Then, start the robotic arm 4. The output end of the robotic arm 4 aligns the laser head 5 with the tire mold on the sliding rod 9, so that it performs laser cleaning on one point on the tire mold. After the tire mold rotates one circle, the output end of the robotic arm 4 moves the laser head 5 to align the laser head 5 with other points on the tire mold until the entire tire mold is cleaned.
