[0034] 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.

[0035] Specifically, the laser cleaning device 100 includes a drive mechanism 10, a laser cleaning mechanism 20, and at least one jig platform 30. The drive mechanism 10 is used to drive the laser cleaning mechanism 20 to perform cleaning at multiple angles. The jig platform 30 is used to place the tire mold to be cleaned. The drive mechanism 10 drives the laser cleaning mechanism 20 to a preset position to clean the tire mold. In this application, the jig platform 30 can drive the tire mold to rotate, thereby cooperating with the drive mechanism 10 to adjust the relative position of the laser cleaning mechanism 20 and the tire mold.

[0036] In the present application, the driving mechanism 10 may be a robotic arm or other multi-axis driving device, capable of driving the laser cleaning mechanism 20 to move at multiple angles. In the present application, the driving mechanism 10 is explained by taking a multi-axis driving device as an example.

[0037] like Figure 2 As shown, the driving mechanism 10 includes a turntable 12, a first slide 13 and a second slide 14. The turntable 12 is fixed to the mounting shell 11.

Specifically, the mounting shell 11 can be the outer shell body of the equipment or other fixed platform, and the turntable 12 is fixed on the top surface of the mounting shell 11. The turntable 12 can be a rotary cylinder, a rotary motor or other devices, as long as it can drive the first slide 13 to rotate in the R1 axis. In this application, the R1 axis is a vertical axis perpendicular to the horizontal plane.

[0038] In the present application, the first slide 13 and the second slide 14 can be linear drive structures such as linear motors, screw drives, or belt drives, and are primarily used to drive the laser cleaning mechanism 20 to move within a linear range. The Y-axis and the Z-axis are perpendicular to each other. This application also involves an X-axis, which is perpendicular to both the Y-axis and the Z-axis.

[0039] When the laser cleaning mechanism 20 needs to be driven, the jig platform 30 will move to a preset position together with the tire mold, and the turntable 12, the first slide 13 and the second slide 14 will cooperate to adjust the relative position of the laser cleaning mechanism 20, so that the laser cleaning mechanism 20 moves to the working station, and then the tire mold is laser cleaned.

The tire mold can be placed on the rotating platform 33. The rotating drive device 32 can drive the tire mold to rotate through the rotating platform 33 to adjust the position of the tire mold relative to the laser cleaning mechanism 20.

[0042] In the present application, a plurality of position sensors 312 are provided on the bracket 31 , and the plurality of position sensors 312 are evenly distributed around the circumference of the rotating platform 33 to identify the position of the tire mold.

[0043] Furthermore, a plurality of universal wheels 311 are provided at the bottom end of the bracket 31 , and the bracket 31 can be moved by the universal wheels 311 to adjust the position of the fixture platform 30 , thereby improving the flexibility of the device.

[0044] In the present application, there are two jig platforms 30 , which can be used to place different tire molds or different mold side panels on the same tire mold, which is not specifically limited in the present application.

[0045] Furthermore, the laser cleaning mechanism 20 can be used to emit two cleaning lasers simultaneously, so as to clean the tire mold at the same time.

[0046] like Figure 4 Specifically, the laser cleaning mechanism 20 includes a fixed base 21, a first optical path component 25, a second optical path component 26, a first light source 23, and a second light source 24.

[0052] In the present application, the light emitted by the first light source 23 first passes through the first light guide hole 213, is then transmitted to the third light guide hole 2511 under the action of the first reflector 217, is then transmitted to the fourth light guide hole 2512 under the action of the third reflector 254, and is then transmitted to the first galvanometer mirror 253 under the action of the fourth reflector 255.
