Description

Technical Field

[0002] Laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece, causing the dirt, rust or coating on the surface to evaporate or peel off instantly, and quickly and effectively remove the surface attachments or surface coatings of the cleaning object, thereby achieving a clean process. Laser cleaning technology is a new technology based on the interaction effect between laser and matter. Unlike traditional mechanical cleaning, chemical cleaning and ultrasonic cleaning methods, laser cleaning does not require any CFC organic solvents that damage the ozone layer, is pollution-free, noise-free, harmless to the human body and the environment, and is a "green" cleaning technology.

[0037] As Figure 1 and Figure 2 shown, the present application discloses a dual - path laser cleaning device 100, and the laser cleaning device 100 cooperates with a transmission line 200. The laser cleaning device 100 is arranged on the transmission path of the transmission line 200, and the transmission line 200 is used to move the mold to be cleaned to the laser cleaning device 100, and the mold is cleaned by the laser cleaning device 100.

[0038] The cleaning device 100 includes a cleaning housing 10, and the transmission line 200 passes through the cleaning housing 10. The transmission line 200 can move the mold into the cleaning housing 10 and the mold is cleaned by the cleaning device 100. After the cleaning device 100 finishes cleaning the mold, the transmission line 200 can drive the mold away from the cleaning housing 10.

[0039] In the present application, the transmission line 200 can be one of a roller transmission device, a belt transmission device, and a chain transmission device, which is mainly used for transmitting the mold and can drive the mold to move within a spatial range. The specific structure and transmission method of the transmission line 200 are not limited in the present application.

[0040] Furthermore, a transmission fixture 210 is arranged on the transmission line 200, and at least one mold is placed on one transmission fixture 210. The transmission line 200 drives the mold to move through the transmission fixture 210. Specifically, when the transmission line 200 drives the transmission fixture 210 to drive in one direction, the transmission fixture 210 drives the mold to move synchronously, and the part of the mold to be cleaned is exposed from the transmission fixture 210. In the present application, four placement stations are arranged on the transmission fixture 210, and the transmission fixture 210 can place four molds at the same time. The transmission line 200 drives the molds to move to a preset position one by one through the transmission fixture 210 so that the cleaning device 100 can clean the corresponding positions of the molds.

[0041] In the present application, the mold is a tread block of a mold for processing a tire, and the tread block is used to generate a tread on the tire during tire processing. Transverse ribs and longitudinal ribs are provided on the tread block, and the cleaning device 100 is used to clean the side walls of the transverse ribs and the longitudinal ribs.

[0042] As Figure 2 and Figure 3 shown, further, the cleaning device 100 further includes a driving mechanism 20 and the optical path mechanism 30. The driving mechanism 20 and the optical path mechanism 30 are both arranged in the cleaning housing 10. The driving mechanism 20 is arranged in the cleaning housing 10 to drive the optical path mechanism 30 to move in the X-axis, Y-axis, and Z-axis directions. The optical path mechanism 30 is used to generate laser and perform laser cleaning on corresponding positions of the mold. In the present application, the driving mechanism 20 and the optical path mechanism 30 cooperate to perform laser cleaning on the mold at a preset position.

[0043] In the present application, a cleaning station is provided on the transmission line 200. The cleaning station is inside the cleaning housing 10 and directly below the optical path mechanism 30. The optical path mechanism 30 cleans the mold that has moved to the cleaning station. In the present application, the transmission line 200 drives the mold to move to the cleaning station, at which time the mold is located directly below the optical path mechanism 30. The optical path mechanism 30 identifies the specific position of the mold, and then the driving mechanism 20 and the optical path mechanism 30 cooperate to perform laser cleaning on the side walls of the transverse ribs and the side walls of the longitudinal ribs on the mold.

[0044] In this application, the driving mechanism 20 can drive the optical path mechanism 30 to move in the X-axis, Y-axis, and Z-axis directions. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other pairwise, thereby driving the optical path mechanism 30 to adjust its position within a certain spatial range. Specifically, the driving mechanism 20 includes a first slide table 21, a second slide table 22, and a third slide table 23. The first slide table 21 is fixedly connected to the cleaning housing 10 and drives the second slide table 22 to move in the X-axis direction. The second slide table 22 is used to drive the third slide table 23 to move in the Y-axis direction. The third slide table 23 drives the optical path mechanism 30 to move in the Z-axis direction through a connecting member. In this application, the first slide table 21, the second slide table 22, and the third slide table 23 can adopt existing electronic drive slide tables, lead screw drives, and belt drive devices on the current market, which are mainly used for linear driving of workpieces. Specifically in this application, the first slide table 21, the second slide table 22, and the third slide table 23 can move in the X-axis, Y-axis, and Z-axis directions respectively, thereby driving the optical path mechanism 30 to move within a certain spatial range, so that the optical path mechanism 30 can perform laser cleaning on the structures at different positions of the mold.

[0045] As Figure 4 and Figure 5 shown, the optical path mechanism 30 is arranged directly above the transmission line 200. The optical path mechanism 30 includes a first optical path rotation structure 31, a second optical path rotation structure 32, a first connecting frame 33, and an optical path component 34. The first optical path rotation structure 31 is connected to the driving mechanism 20 to drive the first connecting frame 33 to rotate in the R1-axis direction. The second optical path rotation structure 32 is arranged on the first connecting frame 33. The optical path component 34 is connected to the first connecting frame 33 and is rotationally connected to the first connecting frame 33 in the R2-axis direction. The second optical path rotation structure 32 is used to drive the optical path component 34 to rotate in the R2-axis direction. The plane where it rotates along the R1 axis is perpendicular to the plane where it rotates along the R2 axis. Specifically, the straight line where the R1 axis is located is parallel to the Y-axis direction, and the straight line where the R2 axis is located is parallel to the X-axis direction.

[0046] In the present application, by providing the first optical path rotation structure 31 and the second optical path rotation structure 32, the optical path assembly 34 can be driven to rotate in the directions of the R1 axis and the R2 axis. After being combined with the drive mechanism 20, five-axis drive of the optical path assembly 34 can be achieved, improving the precision of the optical path assembly 34 and enabling different positions of the mold to be cleaned through the optical path assembly 34. Moreover, when it is necessary to clean the side walls of the horizontal ribs and vertical ribs of the pattern block, the optical path assembly 34 is driven on the X axis, Y axis, Z axis, R1 axis, and R2 axis, thereby ensuring the precision during the cleaning of the horizontal ribs and vertical ribs.

[0047] Furthermore, the optical path assembly 34 includes a first light source 35 and a first optical path device 341 that cooperate with each other, and a second light source 36 and a second optical path device 342 that cooperate with each other; the first light source 35 and the second light source 36 are arranged on the first connecting frame 33, the first optical path device 341 and the second optical path device 342 are rotationally connected to the first connecting frame 33, and the second optical path rotation structure 32 can drive the first optical path device 341 and the second optical path device 342 to rotate in the direction of the R2 axis. In the present application, by providing two optical path devices and two light sources, with one optical path device corresponding to one light source, laser cleaning of two opposite side walls of the horizontal ribs and vertical ribs can be achieved, improving the cleaning efficiency. Moreover, under the action of five-axis drive, the cleaning precision can also be ensured.

[0048] In the present application, both the first optical path device 341 and the second optical path device 342 are rotationally connected to the first connecting frame 33, and the second optical path rotation structure 32 can drive the first optical path device 341 and the second optical path device 342 to rotate synchronously in the direction of the R2 axis.

[0049] In the present application, the first optical path rotation structure 31 and the second optical path rotation structure 32 have the same structure, both including a drive motor and corresponding rotating connectors. By driving the rotating connectors to rotate, the drive motor can drive the first connecting frame 33 to rotate around the R1 axis and drive the optical path assembly 34 to rotate in the direction of the R2 axis.

[0050] Specifically, the first connecting frame 33 includes a first connecting portion 331, a second connecting portion 332, and a third connecting portion 333. The first connecting portion 331 is rotatably connected to the first optical path rotating structure 31. The second connecting portion 332 and the third connecting portion 333 are located on the same side of the first connecting portion 331 and are oppositely arranged. The first optical path device 341 and the second optical path device 342 are arranged between the second connecting portion 332 and the third connecting portion 333. The second optical path rotating structure 32 is used to drive the first optical path device 341 and the second optical path device 342 to rotate between the second connecting portion 332 and the third connecting portion 333. The first optical path device 341 is rotatably connected to the second connecting portion 332, the second optical path device 342 is rotatably connected to the third connecting portion 333, and the first optical path device 341 and the second optical path device 342 are connected by a connecting plate 334. The second optical path rotating structure 32 can drive the first optical path device 341 to rotate around the R2 axis, and the first optical path device 341 drives the second optical path device 342 to rotate synchronously through the connecting plate 334. In this application, the first connecting frame 33 is a metal profile. The first connecting portion 331 is connected to the first optical path rotating structure 31, and the first optical path rotating structure 31 can drive the first connecting portion 331 to rotate in the R1 axis direction, thereby driving the entire first connecting frame 33 to rotate. In this application, the first optical path rotating structure 31 can drive the first connecting frame 33 to rotate between 0 and 360 degrees. The second optical path rotating structure 32 can drive the first optical path device 341 and the second optical path device 342 to rotate synchronously in the R2 axis direction. Specifically, the second optical path rotating structure 32 can drive the first optical path device 341 and the second optical path device 342 to rotate between 0 and 360 degrees. Specifically, the first optical path device 341 and the second optical path device 342 are fixedly connected by a connecting plate 334. Therefore, when the second optical path rotating structure 32 drives the first optical path device 341 to rotate along the R2 axis direction, the first optical path device 341 can drive the second optical path device 342 to rotate synchronously through the connecting plate 334.

[0051] In this application, the first optical path device 341 and the second optical path device 342 are arranged at intervals, and the first optical path device 341 and the second optical path device 342 can perform laser cleaning on two side walls of the horizontal rib or two side walls of the vertical rib.

The light recognition device 37 is located between the first optical path device 341 and the second optical path device 342, and the light recognition device 37 acts on the mold at the cleaning station. The light recognition device 37 moves synchronously with the optical path assembly 34. In this application, when the transmission line 200 drives the mold to move to the cleaning station, the light recognition device 37 can recognize the specific position of the mold. A corresponding software control algorithm is set in the entire cleaning device, and the actions of the driving mechanism 20 and the optical path mechanism 30 can be controlled according to the position and related shape information of the mold recognized by the light recognition device 37, so as to perform laser cleaning on the horizontal ribs and vertical ribs on the mold through the first optical path device 341 and the second optical path device 342.

[0053] In this application, the light recognition device 37 is a light sensor, which can be a scanning device, etc., and is not limited here.

The first light source 35 is connected to a corresponding laser, and the laser emits laser light through the light source. After the first light source 35 emits laser light, it is transmitted to the second light channel 336 under the action of the first reflector 38, and then transmitted to the first optical path device 341 through the second light channel 336, and the laser cleaning of the mold is realized through the first optical path device 341.

The fourth optical channel 338 penetrates through the third connecting portion 333 and communicates with the second optical path device 342. In the present application, the central axis of the third optical channel 337 and the central axis of the fourth optical channel 338 are vertically distributed. The third optical channel 337 and the fourth optical channel 338 communicate with each other. One end of the third optical channel 337 and one end of the fourth optical channel 338 communicate with each other.
