[0020] like Figure 1 As shown, the present application discloses a dual-light path laser cleaning device 100 for a tire mold, which is mainly used for continuous laser cleaning of the side panels of the tire mold.

[0021] Specifically, the laser cleaning device 100 includes a driving mechanism 10, a laser cleaning mechanism 20, and at least one fixture platform 30. The driving mechanism 10 is used to drive the laser cleaning mechanism 20 to clean at multiple angles. The fixture platform 30 is used to place the tire mold to be cleaned. The driving mechanism 10 drives the laser cleaning mechanism 20 to move to a preset position and then cleans the tire mold. In the present application, the fixture platform 30 can drive the tire mold to rotate, and then cooperate with the driving mechanism 10 to adjust the relative position of the laser cleaning mechanism 20 and the tire mold.

[0022] In the present application, the driving mechanism 10 may be a robot arm or other multi-axis driving device, which can drive the laser cleaning mechanism 20 to move at multiple angles.
