[0035] like Figure 1 and Figure 2 As shown, the present application discloses a single-light path laser cleaning device for tire molds, which is used for laser cleaning the upper side plate mold 200 and the lower side plate mold 300 of the tire. In the present application, the upper side plate mold 200 has two surfaces to be cleaned, one is the top surface of the upper side plate mold 200, and the other is the inner side surface of the upper side plate mold 200. The inner side surface of the upper side plate mold 200 is the pattern block; the surface to be cleaned on the lower side plate mold 300 is the bottom surface of the lower side plate mold 300. The cleaning device can realize laser cleaning of the top surface, pattern block and bottom surface of the upper side plate mold 200 and the need to replace different equipment, and the degree of automation is high.

[0036] Furthermore, the cleaning equipment includes a first driving mechanism 10, a second driving mechanism 20 and an optical path mechanism 30. The first driving mechanism 10 is used to drive the second driving mechanism 20, and the second driving mechanism 20 is used to drive the optical path mechanism 30. The first driving mechanism 10 and the second driving mechanism 20 cooperate to drive the optical path mechanism 30 to change position in multiple directions to enhance the flexibility of the optical path mechanism 30. After moving to a preset position, the optical path mechanism 30 can realize laser cleaning of the upper plate mold 200 and the lower plate mold 300.

[0037] In the present application, when the cleaning equipment cleans the upper plate mold 200 and the lower plate mold 300, the optical path mechanism 30 is located between the upper plate mold 200 and the lower plate mold 300. After the cleaning equipment completes the laser cleaning of one of the molds, it moves to other preset positions under the action of the first drive mechanism 10 and the second drive mechanism 20, and then continues to clean the other mold under the action of the first drive mechanism 10 and the second drive mechanism 20.

[0038] In the present application, when the cleaning device is working, the upper plate mold 200 is arranged directly above the lower plate mold 300, and the optical path mechanism 30 is located between the upper plate mold 200 and the lower plate mold 300 when working.

[0039] Specifically, the first driving mechanism 10 drives the second driving mechanism 20 to move at least in the Y-axis direction, so as to move the optical path mechanism 30 between the upper plate mold 200 and the lower plate mold 300 through the second driving mechanism 20 .

[0040] Please continue to see Figure 3 Furthermore, the first drive mechanism 10 includes a horizontal drive device 11, which includes a first telescopic shaft 111. The output end of the first telescopic shaft 111 is connected to the second drive mechanism 20 and can drive the second drive mechanism 20 in the Y-axis direction. In the present application, the first telescopic shaft 111 can be at least one of an electric cylinder, an electric slide, a linear motor, etc., as long as it can be used to drive the second drive mechanism 20 in the Y-axis. The specific structure is not limited in this application.

[0041] Furthermore, the horizontal drive device 11 also includes a second telescopic shaft 112, the output shaft of which is connected to the first telescopic shaft 111, and the second telescopic shaft 112 can drive the first telescopic shaft 111 on the Y-axis. Specifically, the second telescopic shaft 112 can have the same structure as the first telescopic shaft 111, or a different structure. The second telescopic shaft 112 can be at least one of an electric cylinder, an electric slide, a linear motor, etc., as long as it can be used to drive the first telescopic shaft 111 on the Y-axis. The specific structure is not limited in this application.

[0042] In the present application, the driving accuracy of the first telescopic shaft 111 is different from the driving accuracy of the second telescopic shaft 112. Specifically, the driving accuracy of the first telescopic shaft 111 is greater than the driving accuracy of the second telescopic shaft 112. When the mold needs to be laser cleaned, the optical path mechanism 30 can be moved to a preset position through the second telescopic shaft 112, and then the first telescopic shaft 111 can accurately drive the optical path mechanism 30 according to the overall driving requirements of the equipment, thereby improving the position accuracy of the optical path mechanism 30 and thus improving the cleaning accuracy.

[0043] The first driving mechanism 10 also includes a vertical driving device 12 and a turntable device 13. The vertical driving device 12 is connected to the second telescopic shaft 112 and can drive the second telescopic shaft 112 in the Z-axis direction; the output end of the turntable device 13 is connected to the vertical driving device 12, and the turntable device 13 can drive the vertical driving device 12 to rotate around the R4 axis; the R4 axis is parallel to the Z axis. In the present application, the turntable device 13 is installed in a preset position or device, and the vertical drive device 12 is fixed to the output shaft of the turntable device 13. The turntable device 13 can drive the vertical drive device 12 to rotate around the R4 axis to adjust the position of the vertical drive device 12. In the present application, one end of the first telescopic shaft 111 is connected to the optical path mechanism 30, and the other end of the first telescopic shaft 111 is connected to one end of the second telescopic shaft 112, that is, connected to the output end of the second telescopic shaft 112. The end of the second telescopic shaft 112 away from the first telescopic shaft 111 is connected to the output end of the vertical drive device 12. When the turntable device 13 drives the vertical drive device 12 to rotate around the R4 axis, the vertical drive device 12 can drive the horizontal drive device 11 to rotate synchronously. In the present application, the vertical drive device 12 is used to drive the horizontal drive device 11 to move in the Z-axis direction, and then drive the second drive mechanism 20 and the optical path mechanism 30 to synchronize positions through the horizontal drive device 11. Specifically, the vertical drive device 12 and turntable device 13 are not only used to drive the optical path mechanism 30 to a preset position via the horizontal drive device 11, but also cooperate with other drive mechanisms to drive the optical path mechanism 30 when the optical path mechanism 30 cleans the mold, allowing the optical path mechanism 30 to laser clean the corresponding position of the mold according to the preset cleaning data. Specifically, the straight line on which the R4 axis is located is perpendicular to the Y axis within the spatial range.

[0044] In the present application, the turntable device 13 can be a rotating motor, a turntable cylinder, etc., or a structure in which a motor drives a rotating shaft to rotate, etc., which is not specifically limited in the present application.

[0045] Furthermore, the vertical drive device 12 is one of a linear motor, a screw drive mechanism, and an electric slide, which is not specifically limited in this application.

[0046] Furthermore, the first drive mechanism 10 also includes an electric flat cart 14, to which the turntable device 13 is fixed. The electric flat cart 14 can drive the displacement of the cleaning device. The electric flat cart 14 is an automatically driven trolley that can be used to drive the first drive mechanism 10 to move to a certain position on a certain plane. The electric flat cart 14 is an existing drive trolley and can be selected from existing commercial equipment to meet the needs of the entire cleaning device. The specific structure will not be described in detail in this application.

[0047] like Figure 3 As shown, in the present application, the second driving mechanism 20 is located between the upper plate mold 200 and the lower plate mold 300, and the second driving mechanism 20 includes a first rotating component 21, a second rotating component 22 and a third rotating component 23. The first rotating component 21 can drive the second rotating component 22 to rotate in the R1 axis direction; the second rotating component 22 can drive the third rotating component 23 to rotate in the R2 axis direction; the third rotating component 23 can drive the optical path mechanism 30 to rotate in the R3 axis direction; the straight line where the R1 axis is located, the straight line where the R2 axis is located, and the straight line where the R3 axis is located are perpendicular to each other in the projection perpendicular to the Y axis direction; a laser emission port 321 is provided on the optical path mechanism 30, and the optical path mechanism 30 is used to perform laser cleaning on the upper plate mold 200 and the lower plate mold 300.

[0048] In the present application, the first rotating assembly 21, the second rotating assembly 22, and the third rotating assembly 23 cooperate with each other to form a three-axis mechanical drive device, which drives the optical path mechanism 30 in the R1 axis, R2 axis, and R3 axis directions respectively. In addition, the first driving mechanism 10 and the second driving mechanism 20 cooperate to drive the optical path mechanism 30 in the R1 axis, R2 axis, R3 axis, Y axis, Z axis, and R4 axis directions, thereby improving the cleaning accuracy of the optical path mechanism 30. In the present application, the straight line on which the R2 axis is located is parallel to the straight line on which the R4 axis is located.

[0049] In the present application, the first rotating assembly 21, the second rotating assembly 22 and the third rotating assembly 23 have the same structure. Specifically, they all include a driving motor and a rotating shaft. The driving motor drives the rotating shaft to rotate to achieve rotational drive.

[0050] Furthermore, the straight line where the R1 axis is located is parallel to the Y axis, the straight line where the R2 axis is located is parallel to the Z axis; the straight line where the R3 axis is located is parallel to the X axis, and the X axis, Y axis and Z axis are perpendicular to each other. Through the above structure, the multi-axis rotation drive of the optical path mechanism 30 is realized, driving the optical path mechanism 30 to rotate in multiple directions.

[0051] like Figure 1 and Figure 4 As shown, in the present application, the optical path mechanism 30 is used to cooperate with the light source mechanism 40, and the laser emitted by the light source mechanism 40 is emitted through the laser emission port 321 of the optical path mechanism 30 to achieve laser cleaning of the mold.

[0052] Specifically, the light source mechanism 40 includes a light source body (not shown), a first light guide 41, a first reflector 42, a second light guide 43, a second reflector 44 and a third light guide 45, wherein the light source body is fixedly connected to the first rotating component 21, the first light guide 41 is hollow, the first light guide 41 connects the light source body and the first reflector 42, the first reflector 42 is fixed in the second rotating component 22, the light emitted by the light source body can be transmitted to the first reflector 42 through the first light guide 41, and the light is reflected to the second light guide 43 by the first reflector 42, the second light guide 43 is hollow, the second light guide 43 connects the first reflector 42 and the second reflector 44, the second light guide 43 transmits the light to the second reflector 44, the light is reflected by the second reflector 44, and then transmitted to the optical path mechanism 30 through the third light guide 45, and then emitted through the laser emission port 421.

[0053] In the present application, the first light guide member 41 is coaxially distributed with the R1 axis, the second light guide member 43 is coaxially distributed with the R2 axis, and the third light guide member 45 is coaxially distributed with the R3 axis. When the first rotating component 21, the second rotating component 22 and the third rotating component 23 are driven to rotate, the transmission of light will not be affected, thereby ensuring the accuracy of light transmission and improving the cleaning effect.

[0055] like Figure 5 and Figure 6As shown, further, the optical path mechanism 30 includes an optical path housing 31, a third reflector 33, a fourth reflector 34, a cleaning field mirror 35 and a protective shell 32. The third reflector 33 and the fourth reflector 34 are both fixed in the optical path housing 31. The optical path housing 31 is connected to the third rotating assembly 23. The third light guide 45 is a straight hole provided in the optical path housing 31. The third light guide 45 connects the second reflector 44 and the third reflector 33. The light reflected by the second reflector 44 is transmitted to the third reflector 33 through the third light guide 45. Then the third reflector 33 reflects it to the fourth reflector 34. The fourth reflector 34 transmits it to the cleaning field mirror 35. After passing through the cleaning field mirror 35, it is emitted from the laser emission port 321. In the present application, the protective shell 32 is fixedly connected to the optical path housing 31, and the cleaning field mirror 35 is fixed in the protective shell 32. The protective shell 32 protects the cleaning field mirror 35. The laser emission port 321 is located at one end of the protective shell 32 .

[0056] The optical path mechanism 30 further includes a laser rangefinder and / or a red light pen 36. The laser rangefinder and the red light pen 36 are used to identify the cleaning position on the mold and the shape of the mold. Based on the shape of the mold, the control terminal in the device generates a cleaning plan for the mold.

[0057] like Figure 7 As shown, in order to clearly describe the cleaning position of the mold in this application, the state of the upper side plate mold 200 and the lower side plate mold 300 during cleaning is described. Specifically, the upper side plate mold 200 is open downward and includes an upper cleaning surface 210 and a side cleaning surface 220. The upper cleaning surface 210 is the top plate of the upper side plate mold 200, and the side cleaning surface 220 is the side surface of the upper side plate mold 200.

[0058] The lower plate mold 300 is opened upward, and includes a lower cleaning surface, which is distributed parallel to the upper cleaning surface 210. The first driving mechanism 10 and the second driving mechanism 20 cooperate to drive the laser emission port 321 toward the lower cleaning surface to clean the lower cleaning surface.

The cleaning equipment can clean the upper side panel mold 200 and the lower side panel mold 300 in a sequence according to a pre-set program. Alternatively, the cleaning equipment can automatically generate motion control data based on position and shape information detected by a sensor device, such as a rangefinder or red light pen, and move according to a self-generated coordinate system to achieve mold cleaning. The specific control method is not limited in this application; any structural feature that meets the requirements of this application constitutes a protective structure.
