Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, in particular to a cleaning device and a cleaning system. Background Art

[0002] During the tire production process, rubber and other residues will remain on the surface of the tire mold when the tire mold is vulcanized. If the mold continues to be used, it will affect the quality of the tire produced. Therefore, the tire mold needs to be cleaned regularly.

[0003] Laser cleaning is currently a common and efficient method for cleaning tire molds. In theory, the cleaning efficiency is highest when the laser is cleaned perpendicularly to the surface of the tire mold. However, due to the presence of various ribs and steel sheets in the tread blocks of the tire mold, the laser cannot clean every part of the tread block perpendicularly.

[0004] The cleaning device in the prior art can usually only vertically clean the tread block steel sheets and rib side walls with a specific spacing to height ratio. For the tread block steel sheets with a smaller spacing and a higher height, the spacing to height ratio is usually converted before cleaning. Although the rib side walls can also be cleaned, the cleaning effect will be reduced.

[0005] Therefore, there is an urgent need for a cleaning device that uses laser to clean pattern blocks and can meet multi-angle requirements and ensure cleaning effects. Summary of the invention

[0006] In view of this, the present invention provides a cleaning device and a cleaning system to solve the problem that the cleaning device in the prior art cannot meet the multi-angle requirements and ensure the cleaning effect.

[0007] In a first aspect, the present invention provides a cleaning device, comprising:

[0008] Cleaning head;

[0009] A first connecting structure, one side of which is fixedly connected to the cleaning head;

[0010] A first rotating assembly, connected to the other side of the first connecting structure, the first rotating assembly is used to drive the first connecting structure to rotate along a first axis;

[0011] a second connecting structure connected to the first rotating assembly;

[0012] A second rotating assembly, one end of which is connected to the second connecting structure, the second rotating assembly is used to drive the second connecting structure to rotate along a second axis, and the second axis is in a direction different from that of the first axis;

[0013] A first limiting component, provided on the first connecting structure and / or the second connecting structure, and used for limiting the rotation angle of the first connecting structure along the first axis;

[0014] And / or, a second limiting component is provided on the second rotating component and / or the second connecting structure, and is used to limit the rotation angle of the second connecting structure along the second axis.

[0015] Beneficial effects: By setting the first rotating component, the first rotating component can drive the first connecting structure to rotate along the first axis. Since the first connecting structure is fixedly connected to the cleaning head, the first rotating component can further drive the cleaning head to rotate along the first axis. By setting the second rotating component, the second rotating component can drive the second connecting structure to rotate along the second axis. Since the second connecting structure is connected to the first rotating component, the second rotating component can further drive the cleaning head to move along the second axis. Since the directions of the first axis and the second axis are different, the cleaning head can realize multi-angle rotation requirements under the drive of the first rotating component and the second rotating component, so that when the cleaning device is used to clean the tread block of the tire mold, no matter what shape the steel sheet of the tread block is, the cleaning head can be rotated to a direction perpendicular to its surface for cleaning to ensure the cleaning effect. At the same time, since there are many structures of the cleaning system for cleaning the tire mold, by setting the first limiting component and / or the second limiting component, the rotation angle of the cleaning head along at least one axis direction can be further limited to prevent the rotation angle from being too large to interfere with other structures of the cleaning system, and avoid the damage of the laser optical fiber caused by large-scale rotation, thereby improving the stability of laser cleaning.

[0016] In an optional embodiment, the first limiting component includes:

[0017] A first limiting structure, provided on the first connecting structure;

[0018] A second limiting structure is provided on the second connection structure, and the second limiting structure is provided in cooperation with the first limiting structure to jointly limit the rotation angle of the first connection structure along the first axis;

[0019] and / or,

[0020] The second limiting component comprises:

[0021] A third limiting structure, provided on the second connecting structure;

[0022] The fourth limiting structure is arranged on the second rotating assembly, and the fourth limiting structure is arranged in cooperation with the third limiting structure to jointly achieve the limitation of the rotation angle of the second connecting structure along the second axis.

[0023] Beneficial effect: By setting the first limiting component to include a first limiting structure and a second limiting structure, and the first limiting structure is arranged on the first connecting structure, and the second limiting structure is arranged on the second connecting structure, the first limiting structure and the second limiting structure cooperate together to achieve the limitation of the rotation angle of the first connecting structure, so that the limiting effect of the first limiting component is more reliable; by setting the second limiting component to include a third limiting structure and a fourth limiting structure, and the third limiting structure is arranged on the second connecting structure, and the fourth limiting structure is arranged on the second rotating component, the third limiting structure and the fourth limiting structure cooperate together to achieve the limitation of the rotation angle of the second connecting structure, so that the limiting effect of the second limiting component is more reliable.

[0024] In an optional embodiment, the first limiting structure is a first limiting hole, the first limiting hole is arranged in an arc shape, and the second limiting structure is a limiting column;

[0025] And / or, the third limiting structure is a limiting column, the fourth limiting structure is a second limiting hole, and the second limiting hole is arranged in an arc shape.

[0026] Beneficial effect: By setting the first limiting structure as the first limiting hole, and the first limiting hole is an arc-shaped hole, the shape setting of the first limiting structure matches the rotation path of the first connecting structure, so that the setting of the first limiting structure will not affect the rotation of the first connecting structure; by setting the fourth limiting structure as the second limiting hole, and the second limiting hole is an arc-shaped hole, the shape setting of the fourth limiting structure matches the rotation path of the second connecting structure, so that the setting of the fourth limiting structure will not affect the rotation of the second connecting structure.

[0027] In an optional embodiment, a line connecting the midpoint of the first limiting structure and the center of the circle is taken as the first starting line, and the rotation angles of the second limiting structure relative to the first starting line in the clockwise and counterclockwise directions are 50° respectively;

[0028] And / or, taking a line connecting a midpoint of the fourth limiting structure and a center of a circle as a second starting line, a rotation angle of the third limiting structure relative to the second starting line in a clockwise direction and a counterclockwise direction is 35° respectively.

[0029] Beneficial effect: When the cleaning device is used to clean the tread blocks of the tire mold, the first connecting structure is equivalent to a rotation along the circumferential direction of the tread blocks. According to the size of the largest tread blocks commonly used, the rotation angle of the first connecting structure during cleaning can be obtained. Meanwhile, taking into account the placement error during cleaning of the tread blocks and the swing angle during cleaning of the outermost steel sheet of the tread blocks, the rotation angle of the cleaning head can be obtained. Then, the line connecting the midpoint of the first limiting structure and the center of the circle can be obtained as the first starting line. The clockwise and counterclockwise rotation angles of the second limiting structure relative to the first starting line are 50° respectively, that is, the line connecting the midpoint of the first limiting structure and the center of the circle is taken as the first starting line. The angle of the first limiting structure is -50° to 50°, so that the setting angle of the first limiting structure can satisfy the cleaning requirements. The demand is met without causing the rotation of the first connecting structure to interfere with other structures; since the cleaning device uses a laser cleaning device to clean the tire mold, the second connecting structure is equivalent to the rotation along the radial direction of the pattern block. Taking into account the swing angle when cleaning the outermost steel sheet of the pattern block and preventing the laser optical fiber from being damaged by a large-angle rotation, it can be obtained that the line connecting the midpoint of the fourth limiting structure and the center of the circle is the second starting line, and the clockwise and counterclockwise rotation angles of the third limiting structure relative to the second starting line are 35° respectively, that is, the line connecting the midpoint of the fourth limiting structure and the center of the circle is the second starting line, and the angle of the fourth limiting structure is -35° to 35°, so that the setting angle of the fourth limiting structure can not only meet the cleaning demand, but also will not cause the rotation of the second connecting structure to interfere with other structures.

[0030] In an optional embodiment, the first limiting assembly includes a first limiting structure and a second limiting structure, and the second limiting assembly includes a third limiting structure and a fourth limiting structure;

[0031] The second connection structure comprises:

[0032] a first connecting portion, the first connecting portion being fixedly connected to the second rotating assembly, and the third limiting structure being disposed on the first connecting portion;

[0034] Beneficial effect: By setting the second connecting structure to include a first connecting part and a second connecting part, and the extension directions of the first connecting part and the second connecting part are different, the first connecting part can be conveniently fixedly connected to the second rotating component, and the first rotating component can be conveniently arranged on the second connecting part, and the third limiting structure and the second limiting structure can be conveniently arranged respectively, so that the cleaning head can meet the requirements of multi-angle rotation while the overall structure is arranged more compactly.

[0035] In an optional embodiment, the first connecting portion and the second connecting portion are arranged in an L-shape, and the cleaning head is arranged in a space enclosed by the first connecting portion and the second connecting portion.

[0036] Beneficial effect: By arranging the first connection part and the second connection part into an L shape, the cleaning head can be arranged in the enclosed space of the first connection part and the second connection part, so that the cleaning head can be arranged close to the second connection structure, making the overall structure of the cleaning device more compact.

[0037] In an optional embodiment, the first rotating assembly includes:

[0040] In an optional embodiment, an escape space is provided at one end of the second connection portion close to the first connection portion;

[0041] The cleaning device includes a third connecting structure, which is arranged at the avoidance space. The first driving assembly is arranged on one side of the third connecting structure, and the transmission assembly is arranged on the other side. The first output shaft is passed through the third connecting structure.

[0042] Beneficial effect: By setting an avoidance space at one end of the second connection part close to the first connection part, the third connection structure can be set in the avoidance space, which facilitates the connection between the third connection structure and the first drive assembly and the transmission assembly, and can reasonably utilize the space, so that the cleaning device occupies a smaller space.

[0043] In an optional embodiment, the transmission assembly includes:

[0044] A first synchronous pulley connected to the first output shaft;

[0045] A second synchronous belt pulley is connected to the first connecting structure, and along the vertical direction, the height of the second synchronous belt pulley is lower than the height of the first synchronous belt pulley;

[0046] A synchronous belt is wound around the first synchronous pulley and the second synchronous pulley.

[0047] Beneficial effect: By configuring the transmission component in the form of a synchronous pulley and a synchronous belt, it is convenient to respectively configure the first rotating component and the first connecting structure at different positions, thereby enabling rational use of space. At the same time, the height of the second synchronous pulley is configured to be lower than that of the first synchronous pulley, thereby forming a height difference between the first synchronous pulley and the second synchronous pulley. The space formed by the height difference can be utilized to configure other structures, thereby making the overall structure of the cleaning device more compact.

[0049] A tensioning structure is arranged at the avoidance space, and the tensioning structure is arranged on one side of the third connecting structure, and is used to drive the third connecting structure to move under the action of an external force to tension the synchronous belt;

[0053] In an optional embodiment, the second rotating assembly includes:

[0054] A second driving assembly has a second output shaft, wherein the second output shaft is fixedly connected to the second connecting structure;

[0055] A first mounting seat is provided with a mounting channel, the second output shaft is passed through the mounting channel, and the fourth limiting structure is provided on a side of the first mounting seat close to the second connecting structure.

[0056] Beneficial effect: By configuring the second rotating assembly to include a second driving assembly and a first mounting seat, the first mounting seat is convenient for assembling the second driving assembly and can be used in conjunction with a fourth limiting structure to make the overall structure of the cleaning device more compact.

[0078] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0079] When cleaning tire molds, cleaning devices in the prior art can usually only vertically clean the tread block steel sheets and rib sidewalls with a specific spacing to height ratio. At this time, the spacing d of the steel sheets and the height h of the steel sheets need to satisfy d / h>tan20°, such as Figure 1 As shown in the figure. For the tread block steel sheets with smaller spacing and higher height, the spacing and height ratio is usually converted before cleaning. Although the side wall of the rib can be cleaned, the cleaning effect will be reduced. Figure 2As shown, when actually cleaning the tread blocks, if you want to achieve a clean and efficient cleaning without dead angles, you must clean the tread blocks in at least four directions, namely, four directions parallel to the cavity of the tread blocks and perpendicular to the cavity of the tread blocks, to clean the tire mold surface and the side walls of the tread blocks to the maximum extent possible, so as to reduce cleaning dead angles and splicing marks between the tread blocks.

[0080] In order to solve this technical problem, a cleaning device is disclosed in the prior art, which includes a cleaning head, a first-axis rotating device and a second-axis rotating device. The first-axis rotating device and the second-axis rotating device are connected by an adapter plate, and the cleaning head is connected to the power output end of the first-axis rotating device. The rotation axis direction of the first-axis rotating device is perpendicular to the rotation axis direction of the second-axis rotating device, so that the cleaning head can be driven to rotate in multiple directions, thereby achieving efficient cleaning of the workpiece. However, the specific structure of the first-axis rotating device and the second-axis rotating device is not disclosed, and the inventor found that in actual use, if the cleaning head can rotate at multiple angles, it is easier to interfere with other structures of the cleaning system during the rotation process, which is inconvenient to use.

[0081] To this end, the applicant has proposed a cleaning device to solve the problem that the cleaning device in the prior art cannot meet the multi-angle requirements and is likely to interfere with other structures during actual use.

[0082] Combine the following Figures 3 to 14 , describing an embodiment of the present invention.

[0083] According to an embodiment of the present invention, on the one hand, a cleaning device is provided, comprising:

[0084] Cleaning head 1;

[0085] A first connecting structure 2, one side of which is fixedly connected to the cleaning head 1;

[0086] A first rotating assembly 3, connected to the other side of the first connecting structure 2, and used to drive the first connecting structure 2 to rotate along the first axis;

[0087] A second connecting structure 4 connected to the first rotating assembly 3;

[0088] A second rotating assembly 5, one end of which is connected to the second connecting structure 4, and the second rotating assembly 5 is used to drive the second connecting structure 4 to rotate along a second axis, and the direction of the second axis is different from that of the first axis;

[0089] A first limiting component, provided on the first connecting structure 2 and / or the second connecting structure 4, and used to limit the rotation angle of the first connecting structure 2 along the first axis;

[0090] And / or, a second limiting component is provided on the second rotating component 5 and / or the second connecting structure 4, and is used to limit the rotation angle of the second connecting structure 4 along the second axis.

[0091] The cleaning device in this embodiment is used to clean the tread blocks of the tire mold, and the cleaning head 1 is a laser cleaning head to achieve the cleaning of the tire mold by laser. As a convertible embodiment, the cleaning device can also be used to clean other workpieces to be cleaned, and there are no excessive restrictions here. As a convertible embodiment, the cleaning head 1 can also be a cleaning head of other forms, which can be actually selected here according to the cleaning effect of the workpiece to be cleaned.

[0092] By setting the first rotating component 3, the first rotating component 3 can drive the first connecting structure 2 to rotate along the first axis. Since the first connecting structure 2 is fixedly connected to the cleaning head 1, the first rotating component 3 can further drive the cleaning head 1 to rotate along the first axis. By setting the second rotating component 5, the second rotating component 5 can drive the second connecting structure 4 to rotate along the second axis. Since the second connecting structure 4 is connected to the first rotating component 3, the second rotating component 5 can further drive the cleaning head 1 to move along the second axis. Since the directions of the first axis and the second axis are different, the cleaning head 1 can move between the first rotating component 3 and the second rotating component 5, the multi-angle rotation requirement is realized, so that when the cleaning device is used to clean the tread block of the tire mold, no matter what shape the steel sheet of the tread block is, the cleaning head 1 can be rotated to a direction perpendicular to its surface for cleaning to ensure the cleaning effect. At the same time, since there are many structures of the cleaning system for cleaning the tire mold, by setting the first limit component and / or the second limit component, the rotation angle of the cleaning head 1 along at least one axial direction can be further limited to prevent the rotation angle from being too large to interfere with other structures of the cleaning system, and avoid the damage of the laser optical fiber due to large rotation, thereby improving the stability of laser cleaning.

[0093] In this embodiment, the extension direction of the first axis is perpendicular to the extension direction of the second axis. As a convertible implementation, the extension direction of the first axis and the extension direction of the second axis may be arranged at other angles to each other, rather than being arranged perpendicularly.

[0094] Specifically, the first connection structure 2 and the second connection structure 4 in this embodiment are both connection plates. As a convertible implementation, the first connection structure 2 and the second connection structure 4 may be connection blocks, or one of the first connection structure 2 and the second connection structure 4 may be a connection plate and the other may be a connection block, or the first connection structure 2 and the second connection structure 4 may be other forms of connection members, and no further restrictions are made here.

[0095] The cleaning device in this embodiment includes a first limit assembly and a second limit assembly, which can limit the rotation angle of the cleaning head 1 along the first axis and the second axis to prevent interference with other structures. As a convertible implementation, the cleaning device can also include only the first limit assembly, or the cleaning device can include only the second limit assembly.

[0096] like Figure 5 and Figure 6 As shown, the first limiting assembly includes: a first limiting structure 201, which is arranged on the first connection structure 2; a second limiting structure 4021, which is arranged on the second connection structure 4, and the second limiting structure 4021 is arranged in cooperation with the first limiting structure 201, and cooperates together to achieve the limitation of the rotation angle of the first connection structure 2 along the first axis. By setting the first limiting assembly to include the first limiting structure 201 and the second limiting structure 4021, and the first limiting structure 201 is arranged on the first connection structure 2, and the second limiting structure 4021 is arranged on the second connection structure 4, the first limiting structure 201 and the second limiting structure 4021 cooperate together to achieve the limitation of the rotation angle of the first connection structure 2, so that the limiting effect of the first limiting assembly is more reliable. As a convertible embodiment, a limiting structure may be provided only on the first connecting structure 2 or only on the second connecting structure 4. For example, a limiting structure, such as a limiting column, may be provided only on the second connecting structure 4 at a position corresponding to the maximum rotation angle of the first connecting structure 2. When the outer surface of the side wall of the first connecting structure 2 rotates to contact with the limiting column, the rotation angle of the first connecting structure 2 is limited. Of course, a limiting column may also be provided only on the first connecting structure 2 at a position corresponding to the maximum rotation angle. When the limiting column rotates to contact with the outer surface of the side wall of the second connecting structure 4, the rotation angle of the first connecting structure 2 is limited.

[0097] Specifically, the first limiting structure 201 is a first limiting hole, the first limiting hole is arranged in an arc shape, and the second limiting structure 4021 is a limiting column. By setting the first limiting structure 201 as the first limiting hole, and the first limiting hole is an arc hole, the shape setting of the first limiting structure 201 matches the rotation path of the first connecting structure 2, so that the setting of the first limiting structure 201 will not affect the rotation of the first connecting structure 2. As a convertible implementation, it is also possible that the first limiting structure 201 is a limiting column, the second limiting structure 4021 is a limiting hole, or the first limiting structure 201 and the second limiting structure 4021 are other limiting structures arranged in cooperation with each other, and no excessive restrictions are made here.

[0098] In this embodiment, the line connecting the midpoint of the first limiting structure 201 and the center of the circle is taken as the first starting line, and the rotation angles of the second limiting structure 4021 relative to the first starting line in the clockwise and counterclockwise directions are 50° respectively. When the cleaning device cleans the tread blocks of the tire mold, the first connecting structure 2 is equivalent to the rotation along the circumferential direction of the tread blocks. According to the size of the largest tread blocks commonly used, such as the size of 380mm×400mm in length×width, the rotation angle of the first connecting structure 2 during cleaning can be obtained, which is generally about 54.7°. Taking into account the placement error when cleaning the tread blocks and the swing angle when cleaning the outermost steel sheet of the tread blocks, the swing angle is generally 20°, and the rotation angle of the cleaning head can be obtained. Then, it can be obtained that the line connecting the midpoint of the first limiting structure 201 and the center of the circle is the first starting line, and the clockwise and counterclockwise rotation angles of the second limiting structure 4021 relative to the first starting line are 50° respectively, that is, the line connecting the midpoint of the first limiting structure 201 and the center of the circle is the first starting line, and the angle of the first limiting structure 201 is -50° to 50°, so that the setting angle of the first limiting structure 201 can meet the cleaning requirements without causing interference to other structures caused by the rotation of the first connecting structure 2. As a changeable implementation, the angle of the first limiting structure 201 may also be set to other angles, and no further restrictions are imposed here.

[0099] Similar to the first limit component, such as Figure 7 and Figure 8 As shown, the second limiting assembly in this embodiment includes: a third limiting structure 4011, which is arranged on the second connection structure 4; a fourth limiting structure 5011, which is arranged on the second rotation assembly 5, and the fourth limiting structure 5011 is arranged in cooperation with the third limiting structure 4011, and cooperates together to achieve the limitation of the rotation angle of the second connection structure 4 along the second axis. By setting the second limiting assembly to include the third limiting structure 4011 and the fourth limiting structure 5011, and the third limiting structure 4011 is arranged on the second connection structure 4, and the fourth limiting structure 5011 is arranged on the second rotation assembly 5, the third limiting structure 4011 and the fourth limiting structure 5011 cooperate together to achieve the limitation of the rotation angle of the second connection structure 4, so that the limiting effect of the second limiting assembly is more reliable. As a convertible embodiment, it is also possible to set the limiting structure only on the first connection structure 2 or only on the second connection structure 4.

[0100] Specifically, the third limiting structure 4011 is a limiting column, and the fourth limiting structure 5011 is a second limiting hole, and the second limiting hole is arranged in an arc shape. By setting the fourth limiting structure 5011 as the second limiting hole, and the second limiting hole is an arc hole, the shape setting of the fourth limiting structure 5011 matches the rotation route of the second connection structure 4, so that the setting of the fourth limiting structure 5011 will not affect the rotation of the second connection structure 4. As a convertible implementation, it is also possible that the third limiting structure 4011 is a limiting hole, and the fourth limiting structure 5011 is a limiting column, or the third limiting structure 4011 and the fourth limiting structure 5011 are other limiting structures arranged in cooperation with each other, and no excessive restrictions are made here.

[0101] In this embodiment, the line connecting the middle point of the fourth limiting structure 5011 and the center of the circle is taken as the second starting line, and the rotation angle of the third limiting structure 4011 relative to the second starting line along the clockwise and counterclockwise directions is 35 degrees respectively. Since the cleaning device for cleaning the tire mold adopts a laser cleaning device, the second connecting structure 4 is equivalent to the rotation along the radial direction of the pattern block. Considering the swing angle when cleaning the outermost steel sheet of the pattern block, which is generally 20 degrees, and preventing the laser optical fiber from being damaged by large-angle rotation, it can be obtained that the line connecting the middle point of the fourth limiting structure 5011 and the center of the circle is taken as the second starting line, and the rotation angle of the third limiting structure 4011 relative to the second starting line along the clockwise and counterclockwise directions is 35 degrees respectively, that is, the line connecting the middle point of the fourth limiting structure 5011 and the center of the circle is taken as the second starting line, and the angle of the fourth limiting structure 5011 is -35 degrees to 35 degrees, so that the setting angle of the fourth limiting structure 5011 can meet the cleaning requirements and will not cause the rotation of the second connecting structure 4 to interfere with other structures. As a convertible implementation, the angle of the fourth limiting structure 5011 may also be set to other angles, and no further restrictions are imposed here.

[0107] Specifically, the first drive assembly in the present embodiment includes a first drive mechanism 301 and a first reduction mechanism 302. The first drive assembly is arranged on the second connection part 402 near the end of the first connection part 401, and is located above the first connection part 401. The extension direction of the first drive assembly is the same as the extension direction of the first connection part 401, so that the first connection part 401 can be used as a support seat of the first drive assembly, which plays a good supporting role for the first drive assembly without the need to set a separate support seat, making the overall structure of the cleaning device simpler. As a convertible embodiment, it is also possible that a separate support seat is set below the first drive assembly, rather than directly setting the first drive assembly above the first connection part 401. As a convertible embodiment, it is also possible that the first drive assembly only includes the first drive mechanism 301, but does not include the first reduction mechanism 302.

[0108] In this embodiment, the first driving mechanism 301 can be a motor, the first speed reduction mechanism 302 can be a speed reducer, and the first output shaft is the output shaft of the speed reducer.

By setting the height of the second synchronous pulley 304 lower than the height of the first synchronous pulley 303, a avoidance space 403 can be set on the second connection portion 402, which is convenient for placing the third connection structure 6, and at the same time, it is convenient to set the first rotating component 3 and the first connection structure 2 at different positions, so that the space can be reasonably used. At the same time, the height of the second synchronous pulley 304 is set lower than the height of the first synchronous pulley 303, so that a height difference is formed between the first synchronous pulley 303 and the second synchronous pulley 304. Other structures can be set in the space formed by the height difference, so that the overall structure of the cleaning device is more compact. As a convertible embodiment, it is also possible that the heights of the first synchronous pulley 303 and the second synchronous pulley 304 are set to be the same, or the height of the second synchronous pulley 304 is higher than the height of the first synchronous pulley 303.

At the same time, the shielding drive can drive the shielding member away from the laser displacement sensor 7 before the cleaning work starts, so as to expose the laser displacement sensor 7 and prevent the shielding member from affecting the normal use of the laser displacement sensor 7.

[0125] Specifically, the second drive assembly in this embodiment includes a second drive mechanism 502 and a second reduction mechanism 503. The extension direction of the second drive assembly is the same as the extension direction of the second axis. The second reduction mechanism 503 is fixedly connected to the first mounting seat 501, which provides a good support for the second reduction mechanism 503.

By providing a cleaning device that can rotate at multiple angles, the cleaning device can drive the cleaning head 1 to rotate at multiple angles, thereby achieving cleaning of different parts of the tread blocks, thereby improving the cleaning effect.
